W O 93/26112 21 1 ~ 7 3 0 P~r/US93/04963 Apparatus for Accepting and Ret~inin~ an Information Card Field of the Invention Generally, this invention relates to informs.tinn card ch~mhers also known as smart card readers and more specifir~11y, a low profile information card rh~mher having a simr1ifie~ n~ing contact configuration.
R~rk~l oulld of the Invention Typically, the type of apparatus described herein are lefe,,ed to as card readers and are used in aprlic~tinnc such 2 0 as telephone billing, h~nking, rin~m~ and mas6 transportation applic~tion~. Recently, the information card ch~mhers are used to allow writing of inform~tior- to the inform~tion cards. The information cards may contain integrated circuits, _icroprocessors, or mPmOry.
2 5 One app1ir~tion of these information card r~h~mher6 is in the radiotelephone market. Inform~tion card rh~mhers are used to read radiotelephone subscriber illentificsltiQn information from an information card typically in the European market. As radiotelephones hecome smaller and 3 0 portable a need arises for a low profile integral inform~tion W O 93/26112 PC~r/US93/04963 211~730 card rh~qmher which can make electrical cont-q.-~t to read and write information to and from inforrnqtion cards.
Previously, radiotelephnnes have included integrated inform~tion card rh~q~mhers using a wiping cont~ct S configuration for the low profile char~q,cteriRtics. In a wiping cQn~-qct configuration, the information card is inserted directly on top of the electncal cont-qcts of the informAti(~n card rh-qmher, cql1~inf~ the front of the informqtion card to wipe the electrical contqr t~. Upon full insertion of the information 1 0 card, the cont-q-cts of the informqtion card rest on the cont-qcts of the inform~tion card rh-qlmher. On cQnt-q-ctc having a gold plq-ting resulting from an electro-electroless pl~ting process, after 10 to 12,000 cycles the gold plAtin~ of the wiping cQntq~
will be removed, mAking CQ~t-q-Ct between the inform~tiQn card 1 5 rh-q-mh~sr and the infor n-qtinn card unreli~hle There is a need for an alternative low profile information card rh-qmh-er which will be reliable beyond 15,000 cycles up to 100,000 cycles.
Sllmmqry of the Invention The present invention encompq-~ses an information card rhqmher. The infor_ation card chamber accepts, retains and mAkes electrical CQr t~ct to an information card. The information card rh~mher makes electrical cont~ct to the 2 5 information card when the information card is properly inserted. The electrical cont~cts are located on the lower platform of the infonnation card rh~ m her. Upon inserting the information card into the information card rh~mher, the inform~tion card is trAn~lAte-l away from the electrical 3 0 cnn~cts. Prior to being fully inserted, the infonmation card is trAn~lAte~l towards the electrical contacts. The two 2 11 -~ 4 7 3 0 tr~nQl~t~n~l device~ allow an inform~tion card to be inserted into the inform~t;orl card rhs~mh~r without eYr~s~ive wiping of t_e elecl~rical cQntqC~ by the inform~tion card.

The tr~n~ onal devices create a l~n~in~ cont~ct configuration in a printed circuit board based product with minim~l volume and weight. In the past, only wiping cont~ctQ
2 5 were used in such a ~mall area. Thus, the nl~mher of cycles is ~ o~ed beyond 15,000 and up to 100,000 cycles in a low profile integrable information card rh~mher.

l 5 FIGS. 2A, B, and C, illustrate the insertion of the inform-stinn card 105 into the inform-o-tion card çhAmher 107 cQntsinefl within the radiotele~h~ne 101 as illustrated in FIG. 1. The inform-shon card rh~mher 107 has at least two platfonns 211, 213 contsining the tro-ngl~stinn 2 0 devices and electncal cQnt-oct4~ In addition to these two platfonns, 211, 213, a third platform _ay be lorete~ o~l.osi~,e the entrance to the informAtion card rh-smher 107, however, the third platfor_ is not necesssry to the invention disclosed herein and it is not illustrated. In the preferred çmho~lim~nt cantilevered springs were chosen forthetr~n~lAtional devices.
However, other trAn~lAti~nAl devices including inrline~l planes and torsional springs _ay be used in a ~imilAr fiA~hion and would still be considered to be within the scope of the invention disclosed herein.
3 ~ In FIG. 2A, the information card 105 has approached the first cAnt~levered spring 201 and has A
~-lhgequently tr~nRl~t~ away from the electrical c( nt~cts 205.
FIG. 2B illustrates inserting the. information card 105 further into the ;..fo...'.~*on card ~h~mher 107. The ~f~ tinn card 105 i8 tr~nsl~te~l by the first c~n~;levered spring 201, clearing the set of electrical contacts 205, thus, avoiding wiping the i~form~tion card 105 on the electncal cQn~ 205.
FIG. 2C illustrate the position of the information card 105 in the inform~t;Qn card ~~h~mher 107 when the 1 0 inform~t;nn card 105 is ~.J~e~ly inserted. Here, the card has , -~he~l gecon~ c~ntilevered spring 203. T'ne sec~n~
~n~ilevt:led spring tr~nsl~tes the information card 105 towards a set of electrical cQnt~cts 205 such that the inform~tion card 105 essPnt;~lly lands on top of the electrical 1 5 cQnts~ct 205 with only a short wiping required to m~int~in a cle~ning function to remove any Q~id~t~on on eit_er the set of cQnt~ct~ 205 or the cQnt~ on the i~o~ ;Qn card 105.
The spring constant of the second r~nt.~levered spring (k2) is greater than the spring constant of the first c~nt~levered 2 0 spring (kl), such that the second c~nt;levered spring 203 ovt:~col,.es the tr~nRl~tion of the first c~ntilp~vered spring 201.
This difference in spring constants allows ~lo~er cQnt~t and pressure between the cQnt~S of the inform~t;on card 105 and the set of electrical cont~cts 205 as required by GSM
2 5 spel ific~tion 11.11.
The set of electrical contacts 205 are illustrated in FIGS. 2A-C
as only one electrical contact, however, different configurations are possible. The set of electrical contacts 205 could be two rows of contacts or multiple contacts on the width of the card. A third 3 0 c~ntilevered spring 207 iB optional and is used to trP.nQl~te the first end of the inform~tion card 105 removing any moment -. ~
created by the se~n~ ~nt~levered spring 203 and the set of electrical cQnt~( tQ 206. In the preferred embo~limPnt~, the spnng oQ~lQt~nt, R of 'che third c~ntilevered spnng 207 would be less than that of the secQn~ cantilevered spring 203. The third - 5 r-ont~levered spring 207 becQmes pertinent to the ~iesign when the emho~limant inrhl~av two row_ of electrical cont-oct6 and a inform-o-t;sn card 105. Then, the third co-nt~levered spring 207 allows l~lO~r electrical c~n~ct between the e lect~ic~l c~nt~rt~ of the information card to both rows of the 1 0 e lec~ic-ql cQnto~t~ of the inform~tion csrd rhomh~r. As illustrated in FIG. 2C, the forces F1 and F2 acting through distance ~ D1 achieve a momentum M1 on the information card 105 grest enough to insure electricsl con~8ct between all of the electricsl con~ovct~ of the inform~tion card snd the electric. l 1 S con~qct~ of the inform-ot~on csrd ch~mhar. Otherwise, the momentum in the information card 105 may cause only one row of the electrical cont~cts to be ~lol elly cQnnecte~l When the inform~;on card 105 is properly inserted as illustrated in FIG. 2C, the electrical contacts of the 2 0 information card 105 rest with the a~l~lo~l;ate amount of pre6sure on the set of electrical contacts 205. This electrical connec~ion couples the main microprocessor 209 to the information card 105 allowing data to be wl;ll~ll to or read from the information card 105 by the microproces60r 209. In 2 5 the ~ feLled embotlimant the information card 105 cf~ntSlinR a read only memory and the inform~ion is only read from the inform~tion card 105 by the main microproces60r 209.
- However, another equally sufficient çmbo~limant information card 105 may cont~in microprocessors, integrated circuits and 3 0 read and write memory such that it may perform many more . .., ~
7 2 ~-147 ~ O
filn~iona. Thug, the connect;onc _ade to the infor~n~t;Qn card may be read, write and power connections, etc.
FIGS. 3A-C illustrate an alternative embodiment of an il~ol~ti~n card r.h~mhP~r 107 cont~inP~ unt~in a - 5 r~liotele~hnn-p~ 101. Here, t_e insertion of the inforrn~qtior~ card 105 into t_e illrol~ ti~n card ch~mherlO7 is j~lPn~ir~l to that illustrated and descrihed in ~?IG. 2 and the l lece~ text. The only difference iB the implçm~Pnts~ n-of an inClinetl plane 301 inPte~~ of the tird r~ntilevered 8pring207 as described in the p~ce~ ~ paragraph. Here, the in~ ne~3 plane provides the same ~mr~;on as the third ~nt~levered spring 207,trs~n~ ti~
the first inserted end of the inform~tion card 105 away from the set of electrical contacts 205, removing the momentum on the inform~ti~n card 105 created by the secQn(l c~ntile.vered spring 203 and the set of electrical cont~cts 205.

as only one electrical contact, however, different configurations are possible. The set of electrical contacts 205 could be two rows of contacts or multiple contacts on the width of the card. A third 3 0 c~ntilevered spring 207 iB optional and is used to trP.nQl~te the first end of the inform~tion card 105 removing any moment -. ~
created by the se~n~ ~nt~levered spring 203 and the set of electrical cQnt~( tQ 206. In the preferred embo~limPnt~, the spnng oQ~lQt~nt, R of 'che third c~ntilevered spnng 207 would be less than that of the secQn~ cantilevered spring 203. The third - 5 r-ont~levered spring 207 becQmes pertinent to the ~iesign when the emho~limant inrhl~av two row_ of electrical cont-oct6 and a inform-o-t;sn card 105. Then, the third co-nt~levered spring 207 allows l~lO~r electrical c~n~ct between the e lect~ic~l c~nt~rt~ of the information card to both rows of the 1 0 e lec~ic-ql cQnto~t~ of the inform~tion csrd rhomh~r. As illustrated in FIG. 2C, the forces F1 and F2 acting through distance ~ D1 achieve a momentum M1 on the information card 105 grest enough to insure electricsl con~8ct between all of the electricsl con~ovct~ of the inform~tion card snd the electric. l 1 S con~qct~ of the inform-ot~on csrd ch~mhar. Otherwise, the momentum in the information card 105 may cause only one row of the electrical cont~cts to be ~lol elly cQnnecte~l When the inform~;on card 105 is properly inserted as illustrated in FIG. 2C, the electrical contacts of the 2 0 information card 105 rest with the a~l~lo~l;ate amount of pre6sure on the set of electrical contacts 205. This electrical connec~ion couples the main microprocessor 209 to the information card 105 allowing data to be wl;ll~ll to or read from the information card 105 by the microproces60r 209. In 2 5 the ~ feLled embotlimant the information card 105 cf~ntSlinR a read only memory and the inform~ion is only read from the inform~tion card 105 by the main microproces60r 209.
- However, another equally sufficient çmbo~limant information card 105 may cont~in microprocessors, integrated circuits and 3 0 read and write memory such that it may perform many more . .., ~
7 2 ~-147 ~ O
filn~iona. Thug, the connect;onc _ade to the infor~n~t;Qn card may be read, write and power connections, etc.
FIGS. 3A-C illustrate an alternative embodiment of an il~ol~ti~n card r.h~mhP~r 107 cont~inP~ unt~in a - 5 r~liotele~hnn-p~ 101. Here, t_e insertion of the inforrn~qtior~ card 105 into t_e illrol~ ti~n card ch~mherlO7 is j~lPn~ir~l to that illustrated and descrihed in ~?IG. 2 and the l lece~ text. The only difference iB the implçm~Pnts~ n-of an inClinetl plane 301 inPte~~ of the tird r~ntilevered 8pring207 as described in the p~ce~ ~ paragraph. Here, the in~ ne~3 plane provides the same ~mr~;on as the third ~nt~levered spring 207,trs~n~ ti~
the first inserted end of the inform~tion card 105 away from the set of electrical contacts 205, removing the momentum on the inform~ti~n card 105 created by the secQn(l c~ntile.vered spring 203 and the set of electrical cont~cts 205.
