Abstract
A security system for a gaming device prevents a door on the gaming device from being opened during a power failure so as to prevent tampering with the controls of the gaming device when no power is supplied to the system. When power is supplied to the system, a processor logs the time of occurrence of detected door openings in a nonerasable programmable memory so as to provide a record thereof. The information is stored in a sequential manner in accordance with the time of occurrence of the door opening events so that the microprocessor can verify the information stored. If any anomalies are detected in the stored information, the microprocessor (10) can prevent operation of the gaming device or generate alarms.

~EST MO~E FOR CA~RYING QUT T~ INVENTION
A gaming device lO as illustrated in Figs. 1 and 2 includes a cabinet 12 and a door 14 through which access to the controls, generally designated 16, of the gaming devic~ may be hadO Th~ door 14 includes a lock 18 that is unlocked by a key 20 rotatirl5~ a lock tang 22 about an axis 24 of the lock 18 in a direction towards a plunger 26 of a solenoid 30 28 so as to all~w the door 14 tu be opened when the plung~r 26 i~ in a compr~s~ed position. ThQ
~301anoid 28 i~ mount~d to an inner wall of the cabinet 12 ~y a bracket 32 so that when th~ plunger 26 is in an extended position, t~e plun~er 26 3~ inter~eres with the rotation of the lock tang ~.
~ ore particularly/ when power i8 ~upplied to the solenoid 28 via a pair of leads 34, the solenoid W093/182S6 PCT~US93/01282 213170~ 4 28 applies a force on the plunger 26 to pull the plunger 26 in towards the body of the solenoid 28, overcoming the force of a spring 30 that biases the plunger 26 towards the cabinet 12 of the gaming device. When the plunger 26 is pulled in towards the body of the solenoid 28, the plunger 26 is not in an interfering relationship with the lock tang 22. Therefore when power is applied to the solenoid 28, the lock tang 22 can be rotated by the key 20 past the plunger 26 to open the door 14. During a power failure, the golenoid 28 does not exert a force on the plunger 26 so that the plunger 26 i~
biased by the spring 30 towards the cabinet 12.
When the plunger 26 is biased towards the cabinet 12 during a power failure, the plunger 26 interfere8 with the lock tang 24 so as to prevent ~he door 14 from being opened by the key 20 durixlg the pow~r failure.
~ n order to monitor the op~ning of thQ door 14 20 while power is applied to the gaming device 10 and thus to the solen~id 28, the gamins device 10 includes a door opan switch 40 a~ depict~d in Fig.
2. The door ope~ switch 40 may be any witch that - is com~only used to detect the opening of a door and 2S which provid~^e a signal that may ~e coupled to a processor such as the microprocessor 42 of the gaming devic:e lo. The microproc~sor 42 control~
the operation of the gaming de~ice 10 in accordance with ~oftware and data respecti~Ply stored in a ~ON
~0 44 and a R~ 46. ~ore particularly, the ; microproces~or 42 c:ontrol~ a video display ~ whic~
~ nterfac:e~ with a pl~yer to present a game in response to th~ d~po~it OI the corr~ct coins as d~tect~d by a coin det~ctor 50.
The microprocessor 42 al~o opera~e~ in accord~nce with a routine su~ as depictsd in ~ig. 3 to record t~e time of occurrence of each door open event detected by the switch 40. The microprocessor W093/18256 2 1 3 1 7 n 7 2 1 3 17 0 7 PCT/US93/012X2 42 records this information in a PROM 52 in a nonvolatile fashion to obviate the need to provide a printed record~ The information recorded in the PROM 52 can also be protected by a password and check sum. Because the information stored in the PROM 52 is machine readable, the microprocessor 42 may transfer the information stored in the PROM 52 via a communication interface 54 ~uch as an RS232 interface or the like to a central ~tation 56 which monitor~ the operation of one or more gaming devices. Further, the microproces30r operating in accordance with the routine depicted in Fig. 4 checks the records stored in the PROM 52 indicating the time of occurrence of each door open event to verify the records. If anomaliec are discovered in the ~tored record~, the microprocessor 42 can prevent continued operation of the ga~ing device and/or generate alarm signals. It is not~d th2t although a P~OM i~ depicted for the me~ory 52, other nonera~able programmable ~emories may be utilized ~uch as a WORM, i.e., ~ write once read many ~2mory.
As shown in Fig. 3, the microprocessor 42 proceeds from a block 60 to a block 62 upon receipt of a door open signal from the d~or open switch 40.
At block 62, the microproc~ssor 42 increments a PR~M
address pointer to a next sequential address. At block ~4 the microprocessor 42 cets the pr~sent address pointer equal to the addresæ incremented to at bloc~ 62 and at block 66, the microproce~sor 42 s~ores the present address pointer. At block 68 the microproces~or ~2 records the date and time of the - de~ected door opening in thQ PRO~ 52 at th2 addr~s~
of the present address pointer. Thus, the microprocessor 42 in a~cordance with th~ routine dep~ctad in Fig. 3 re~ord~ th~ ti~ o~ occurrenc~ of each door opening in a sequential mann~r ~n the PROM
52. This allows the microprocessor 42 operating in accordance with the routine depicted in Fig. 4 to WO93/182~6 2 1 3 1 7 0 7 PCT/US93/01282 verify the information stored in the PROM 52 to determine if the information stored is indeed sequential and in the past.
More particularly, the microprocessor 42 at a block 72 first initializes a vaxiable y to 3.
Thereafter, at block 74, the microprocessor 42 reads the date and time information stored at the address in PROM 52 and at block 76 reads the date and time information stored at ~he next s~quential PROM
address ~1- Therea~t~r, the microproc~ssor 42 at block 78 determine~ whether the date stored at the address * is earlier than the date stored at the next sequential location. If it is, the microprocessor proceeds to block 86 to increment y 15 80 that the data stored at the next equential PRO~
address can be verified against the data stored at the preceding PROM address. If the microprocessor 10 deter~in~ a~ block 78 that the date storQd at the addre 8 ~ i~ not earlier than the date stored at the next sequential address, the microprocessor proceeds to block 80 to determine whether the date stored at the address ~ is e~ual to the date stored at that next sequential address. If the microprocessor determin~s at block 80 that tha two date~ are not ~ual, th~. microprocessor lO proceeds to block 82 to set an alarm fla~ to which the microprocessor 42 ~y respond to by haltin~ the operation of the ~a~ing device or by generating an alar~ ~ignal. If the microproce.sor 42 determines at block 80 that the t~o dates being ao~pared are equal, the microprocesæor proceeds to block 84 to determine w~ether ~he ti~e stored at the addre~s i8 ~arlier than ~he time stored at the next s~qu~ntial address. If the time stored at the addr~s~ * i~ not earlier than the ti~e ~tored at the next sequential address, the ~icroprocessor 42 proceeds to block 82 to set the alarm flag.
Otherwise, the microprocessor 42 proceeds to block 86 to increment the variable y. After incrementing the variable y at block 86, the microprocessor 42 proceed~ to block 88 to determine whether all of the information stored in the ~ROM 52 has been checked and if ~o, the microprocessor 42 exits the routine at block 90.
Because access to the controls 16 of the gaming device lO i8 prevented via the door 14 during a power failure, the controls 16 cannot be tampered with unless the door 14 and cabinet 12 ar~
physically damaged in a way that is readily, visually apparent. There~ore, oE~eration of the ga~ing device 10 will be halted if the controls have been tampered with during a power failure. When 15 power is ~upplied to the gaming device 10, th~
microprocessor 42 monitors th~ door opening ~vents and logs the tLme of occurrence in a man~er to readily indicate possible tampering with the gaming device. Becau~e the informatlon is logged in a machine readable form a~ opposed to on paper, th~
infor~ation can readily be transferred to a central monitoring station. Further, the microproces~or 42 can itself veri~y the data due to the seguential nature in which the data is ~tored ~o as to prevent op~ration of the ga~ing device lO or to generate alarms if any anomalies are detected.
Many modi~ications and variations of the pres~nt in~ention are poæsible in light of the above teachings. Thus it iB to be understQod that, within 3 0 the scop~ o~ the appended claims, the invention may be practiced otherwise than aæ described hereinabove.
In accordance with the present invention, the disadvantages of prior security systems for gaming devices, a~ discussed above, have been o~ercome.

If the microprocessor determin~s at block 80 that tha two date~ are not ~ual, th~. microprocessor lO proceeds to block 82 to set an alarm fla~ to which the microprocessor 42 ~y respond to by haltin~ the operation of the ~a~ing device or by generating an alar~ ~ignal. If the microproce.sor 42 determines at block 80 that the t~o dates being ao~pared are equal, the microprocesæor proceeds to block 84 to determine w~ether ~he ti~e stored at the addre~s i8 ~arlier than ~he time stored at the next s~qu~ntial address. If the time stored at the addr~s~ * i~ not earlier than the ti~e ~tored at the next sequential address, the ~icroprocessor 42 proceeds to block 82 to set the alarm flag.
Otherwise, the microprocessor 42 proceeds to block 86 to increment the variable y. After incrementing the variable y at block 86, the microprocessor 42 proceed~ to block 88 to determine whether all of the information stored in the ~ROM 52 has been checked and if ~o, the microprocessor 42 exits the routine at block 90.
Because access to the controls 16 of the gaming device lO i8 prevented via the door 14 during a power failure, the controls 16 cannot be tampered with unless the door 14 and cabinet 12 ar~
physically damaged in a way that is readily, visually apparent. There~ore, oE~eration of the ga~ing device 10 will be halted if the controls have been tampered with during a power failure. When 15 power is ~upplied to the gaming device 10, th~
microprocessor 42 monitors th~ door opening ~vents and logs the tLme of occurrence in a man~er to readily indicate possible tampering with the gaming device. Becau~e the informatlon is logged in a machine readable form a~ opposed to on paper, th~
infor~ation can readily be transferred to a central monitoring station. Further, the microproces~or 42 can itself veri~y the data due to the seguential nature in which the data is ~tored ~o as to prevent op~ration of the ga~ing device lO or to generate alarms if any anomalies are detected.
Many modi~ications and variations of the pres~nt in~ention are poæsible in light of the above teachings. Thus it iB to be understQod that, within 3 0 the scop~ o~ the appended claims, the invention may be practiced otherwise than aæ described hereinabove.
