To be combined into the chest shape and constitute slide 12 as the last shell 27 and the lower casing 28 of synthetic resin.Be formed with a pair of fastener 27b that makes the outstanding upward opening 27a of operating body 18 and be fastened on the rising portions 28c of lower casing 28 at last shell 27.In addition, on four angles of last shell 27, alternately form guide protrusions 27c and the columned recess 27d that front end is a dome shape, this guide protrusions 27c is inserted in the locking groove 1e of housing 1 slidably, and this columned recess 27d disposes drive pin 14 and back-moving spring 15.On the other hand, be formed with driving projection 28a at lower casing 28, slide protrusion 28b, a pair of rising portions 28c, a pair of variform installing hole 28d and the 28e of pair of notches portion, wherein, it is outstanding downwards and be inserted in first and second slide plates 6 from the central portion of bottom surface to drive projection 28a, 8 slotted hole 6a, 8a, slide protrusion 28b is hemispherical expansion at the place, four angles of bottom surface, a pair of rising portions 28c is fastened on the fastener 27b of shell 27, embed the installation projection 23a of the frame 23 that rotary electrical unit 11 is arranged among a pair of installing hole 28d, the 28e of pair of notches portion is used for avoiding the interference with helical spring 13.And, can obtain the mobile unit 30 of blocking by following manner, that is: movable substrate 10 lift-launchs of rotary electrical unit 11 will be installed on lower casing 28, afterwards, last shell 27 lift-launchs that make operating body 18 pass opening 27a are fastened on movable substrate 10 and with lower casing 28, thereby movable substrate 10 is clamped between last shell 27 and the lower casing 28, to keep movable substrate 10 and rotary electrical units 11 (with reference to Figure 14) with slide 12.Slide 12 is carried on support unit 2 slidably via the slide protrusion 28b on four angles, bottom surface, so the resistance to sliding of this mobile unit 30 is little, thereby can successfully slide mobile to X, Y direction with respect to housing 1.Here, the situation that slide protrusion 28b is arranged at lower casing 28 is illustrated, but also this slide protrusion 28b can be arranged on four angles of last shell 27 sides that constitute slide 12.In addition, in housing 1, on slide 12, be equipped with following blade fin 16, can guide the slip of mobile unit 30 to move.In addition, be inserted in slidably guide protrusions 27c roughly that the groove of cross shape is locking groove 1e, therefore, if mobile unit 30 is to directions X, the Y direction mobile ormal weight that slides, then guide protrusions 27c contacts with the inwall of locking groove 1e, and then can move sliding and be limited.In addition, utilize locking groove 1e and guide protrusions 27c, the slip moving direction that comprises the mobile unit 30 of movable substrate 10 can be limited in directions X and Y direction, and it is mobile to slide beyond this four direction.
Helical spring 13 as conductive component is to have elasticity and implemented the silver-plated spring of nickel bottom on the wire rod of phosphor bronze.For described helical spring 13, an end be the upper end pass the through hole 10d of movable substrate 10 and solder in the 10a of spine, the other end be the bottom pass the through hole 19c of fixing base 3 and solder in the 22c of spine.Therefore, by rotary encoder portion 24, the push-button switch portion 25 detected signals of rotary electrical unit 11, can carry to the 22c of spine of fixing base 3 via the 10a of spine and helical spring 13, and take out to external circuit from terminal 21.This helical spring 13 comprises that the both ends coil diameter is roughly certain, is present in the part between fixing base 3 and the movable substrate 10 in the helical spring 13, is that the slip of following movable substrate 10 is moved and the variant part 13a of strain.In addition, as shown in Figure 8, this helical spring 13 is in no load condition when the not operation of operating body 18, with orthostatism with electric and mechanical connection between movable substrate 10 and the fixing base 3.Here, in the present embodiment, on a sidepiece of movable substrate 10 and the other side, 3 helical springs 13 are set respectively, and are mounted to the position relation of line symmetry.That is, corresponding with each portion of terminal 26 of rotary electrical unit 11 respectively a plurality of helical springs 13 are disposed at the rotation that clips operating body 18 and opposed position with dispersity.In view of the above, can form following structure, that is: when the slide of operating body 18, because acting on the elastic force (counter-force) of the helical spring 13 between fixing base 3 and the movable substrate 10 is disperseed evenly by height, so can movable substrate is parallel mobile with respect to fixing base 3 when operation, and movable substrate 10 is difficult to run-off the straight.
So spring 15 elastic force-applying upward because drive pin 14 is reset is the cam surface 1d Elastic Contact of the front end face of the dome shape of this drive pin 14 and housing 1.Therefore, as shown in figure 12, when the not operation of operating body 18, the leading section of drive pin 14 enters the penetralia of cam surface 1d, and keeps with being stabilized, thereby mobile unit 30 remains in assigned position with the state that does not rock.In addition, when the slide because of operating body 18 makes mobile unit 30 slips mobile, as shown in figure 16, on one side compression reseting spring 15 is on one side with the most inboard extraction from cam surface 1d of the leading section of drive pin 14, therefore, if remove this slide power, then the elastic force of back-moving spring 15 is given as security the deep that is back to cam surface 1d with the leading section of drive pin 14, thereby makes mobile unit 30 automatically restore to as shown in figure 12 initial position.
Blade fin 16 is to overlook down to be the roughly synthetic resin of rectangular shape, forms and the opposed slotted hole 16a of housing 1 central opening 1b.This blade fin 16 carries slidably on slide 12, with the frame 23 of rotary electrical unit 11 only can be inserted among the slotted hole 16a to the Y direction state that moves that slides.In addition, the both ends of the long side direction of blade fin 16 are respectively to be the bend 16b of the L word shape of lower side bending to fixing base 3 sides, and form outstanding laterally projection 16c on these a pair of bend 16b.And each the projection 16c that is arranged at the 16b of pair of curved portion can make blade fin 16 successfully slide mobile to directions X respectively by the opposed parallel pair of inner wall face guiding of housing 1.Therefore, when mobile unit 30 is slided when mobile to directions X, blade fin 16 also slides integratedly and moves, thereby suppresses rocking of operating body 10.In addition, when mobile unit 30 is slided when mobile to the Y direction, though slide 12 is slided with respect to blade fin 16, lead-frame body 23 is mobile owing to the internal face that utilizes being parallel to each other of slotted hole 16a to extend, so can suppress rocking of operating body 18.
Below, the action of the composite operation type input apparatus of such formation is described.At first, if the action during to slide describes, then when the not operation of operating body 18, shown in Figure 15 (b), the driving projection 28a of lower casing 28 pass support unit 2 rectangular aperture 2a central portion and be inserted in each slotted hole 6a, 8a, first slide plate 6 is positioned at the central authorities of directions X and second slide plate 8 is positioned at the central authorities of Y direction.Under this state, if with operating body 18 to the directions X slide, then drive projection 28a and push the sidepiece of slotted hole 6a to same direction, shown in Figure 15 (a), first slide plate 6 is followed mobile unit 30 and is slided to directions X and to move.Therefore, the contact position (contact condition) with respect to the first fixed contact 22a on the fixing base 3 of the son 5 that slides changes, and detects the contact switching signal, can read this detection signal from the terminal 21 of regulation.But, move to directions X along slotted hole 8a owing to drive projection 28a, thus the not variation of the position of second slide plate 8, thereby the relative position of the son 7 and second fixed contact 22b that slides does not change.
Equally, under the state of Figure 15 (b) expression, with operating body 18 during to Y direction slide, push the sidepiece of slotted hole 8a owing to drive projection 28a to same direction, shown in Figure 15 (c), second slide plate 8 is followed mobile unit 30 and is slided to the Y direction and to move, accompany with it, the contact position with respect to the second fixed contact 22b (contact condition) of slip 7 changes, and detects the contact switching signal, can read this detection signal from the terminal 21 of regulation.At this moment, move to the Y direction along slotted hole 6a, so the position of first slide plate 6 does not change owing to drive projection 28a.
In addition, if making mobile unit 30 so slides mobile to directions X or Y direction, both ends were soldered in each helical spring 13 of movable substrate 10 and fixing base 3 about then slide power also affacted, as shown in figure 17, because the variant part 13a of each helical spring 13 between two substrates 3,10 be strain also, so both ends (solder portion) do not have service load fully up and down, thereby can freely make each helical spring 13 along with the slip of movable substrate 1 is moved and moved.
Here, if slide mobile to directions X or Y direction mobile unit 30, as mentioned above, then while making back-moving spring 15 compression with the deep extraction (with reference to Figure 16) of the leading section of drive pin 14 from cam surface 1d, if so remove slide power, then the elastic force of back-moving spring 15 presses on the deep of cam surface 1d with the leading section of drive pin 14, thereby mobile unit 30 is automatically reset to initial position.
Below, the action during to rotary manipulation describes.Be installed on the movable substrate 10 if will have the rotary electrical unit 11 of operating body 18, make operating body 18 rotary manipulations, then can utilize the rotary encoder portion 24 that is arranged in the rotary electrical unit 11 to detect its rotation amount and direction of rotation.This detection signal is transported to the spine 10a corresponding with movable substrate 10 via the portion of terminal 26 of the regulation of rotary electrical unit 11, therefore, via the helical spring 13 of solder in the conductivity of the 10a of this spine, the detection signal in the time of can reading rotary manipulation from the terminal 21 of the regulation of fixing base 3.
Below, if the action during to push describes, then can utilize the push that is arranged on the push-button switch portion 25 detecting operation bodies 18 in the rotary electrical unit 11.This detection signal is transported to the spine 10a corresponding with movable substrate 10 via the portion of terminal 26 of the regulation of rotary electrical unit 11, therefore, can be via the helical spring 13 of solder in the conductivity of the 10a of this spine, the detection signal when the terminal 21 of the regulation of fixing base 3 reads rotary manipulation.
