Description

  The present invention relates to a configuration of a push button type switch device used in a gaming machine or the like.

  Conventionally, a slot machine or a pachinko machine as a gaming machine has a push button type switch device that is pushed by a player. For example, in a slot machine, a plurality of push button type switch devices arranged corresponding to a plurality of reels are provided, and an operator presses these switch devices to perform operations such as bet input and reel stop. Is done. For each operation, the operation state can be visually recognized by turning on a light emitting element provided on the lower surface side (inner surface side) of the push button portion in the switch device. In a pachinko machine, a switch device is used as a mode changeover switch for changing a game mode and the like, so that the presentation content, BGM, and the like of the liquid crystal display device are changed by pressing the switch device in each game. It has become.

  As a push button type switch device, for example, in the one described in Patent Document 1, a case as a switch main body is integrally formed on the inner periphery of a trunk portion having an oval space in plan view and its vertically middle portion. A substrate mounting portion. The circuit board is screwed to the surface (upper surface) of the substrate mounting portion. Three light emitting diodes are provided on the front surface (upper surface) of the circuit board at appropriate intervals in the longitudinal direction, and a photo interrupter protrudes downward from the rear surface (lower surface) of the circuit board at the center in the longitudinal direction. Is provided. The photo interrupter arranged so that the light emitting element and the light receiving element face each other in the horizontal direction is projected downward through a through hole formed in the substrate mounting portion.

  On the other hand, the push button member has a front surface portion that is touched by an operator's finger and a movable body that is connected and fixed to the lower surface side of the front surface portion. The movable body includes a first arm projecting upward from four corners of the outer periphery of the flat plate portion, an engaging claw formed at the tip (upper end) of each first arm, and a longitudinal direction on the long side of the flat plate portion A second arm projecting upward in the central portion, a long hole formed in the flat plate portion through which the photo interrupter can pass downward, and between the light emitting element and the light receiving element in the central portion of the long hole. And a light-shielding portion that is arranged and can block inspection light.

  The four first arms of the movable body protrude upward along the inner periphery of the case body through holes formed in the substrate mounting portion, and the engaging claws of each first arm engage with the front portion of the push button member. It is fitted and fixed in the hole. Two opposing second arms are provided with a vertically long guide groove, and the side surface of the projecting portion projecting from the inner peripheral surface of the body portion is in sliding contact with the guide groove in the vertical direction. Thus, when the push button member is pushed into the case, the protrusion is guided in the guide groove.

A compression coil spring that urges the movable body and thus the push button member upward (non-operating position) is interposed between the back cover that closes the lower end of the body portion of the case and the movable body. With such a configuration, in the non-operation position, the light shielding portion in the movable body is positioned between the light emitting element and the light receiving element, and the inspection light is blocked and the OFF state can be detected. On the other hand, when the push button member is pushed into the case, the light-shielding portion comes off between the light-emitting element and the light-receiving element as the movable body descends against the biasing force of the compression coil spring, and receives the inspection light. Thus, the ON state can be detected.

That is, since the guide grooves of the two second arms provided opposite to the central portion in the longitudinal direction of the movable body of the push button member are in sliding contact with the protrusions protruding from the inner periphery of the case body, When the operator pushes in one end portion (one corner) of the push button member in the longitudinal direction, the push button member, and thus the movable body is inclined so that the side on which the pushing force is applied is first lowered, and the protrusion and guide groove The sliding surface between them will be kinked. Therefore, there is a problem that the push button member cannot be lowered smoothly, or that the push button member, and hence the movable body, cannot be lowered uniformly as a whole. In the former case, there is a problem that the durability of the switch device is inferior, for example, when the sliding surfaces of the projection and the guide groove are roughened, or in the severe case, the projection or the second arm is damaged.

  In the latter case, the amount of displacement is negligible even if the light shielding portion is hardly displaced. Therefore, even if the push button member is pushed by the players, the push operation may not be detected.

  The present invention has been made to solve the above-described conventional problems, and is a switch device that can easily perform a push operation of the switch device, has durability, and can reliably detect the push operation. Is intended to provide.

As shown in FIGS. 3 (a), 3 (b), 4 (a) to 5 (b) and 7, the guide support member 6 is made of a synthetic resin having high bending strength and wear resistance. The first link member 61 and the second link member 62 are crossed in an X shape in a side view, and are pivotally supported at 63 pivot pins so that the cross depression angle can be varied.

  As can be understood from the perspective view of FIG. 7, the first link member 61 in the guide support member 6 integrally connects the pair of arm portions 611 and 612 and the end portions of the pair of arm portions 611 and 612. The connecting pieces 613, 614 and a pair of pin portions 64a, 64b, 65a, 65b projecting laterally outward are provided at both ends of the respective arm portions 611, 612. The arm portions 611 and 612 are respectively provided with pivot pins 63 and 63 at midway portions in the longitudinal direction, for example, at a half point (center portion) between the pair of pin portions 64a and 64b (65a and 65b). It projects integrally outward.

  Similarly, the second link member 62 includes a pair of arm portions 621 and 622, connecting pieces 623 and 624 that integrally connect the ends of the pair of arm portions 621 and 622, and the arm portions 621 and 621, respectively. A pair of pin portions 66 a, 66 b, 67 a, and 67 b that protrude laterally inward are provided at both ends of 622. Further, the arm portions 621 and 622 are provided with pivot pins 63 and 63 at midway portions in the longitudinal direction, for example, at a half position (center portion) between the pair of pin portions 66a and 66b (67a and 67b). A pair of pivot holes 68 into which are fitted are formed.

  In the through hole 70 surrounded by the pair of arm portions 621 and 622 and the pair of connecting pieces 623 and 624 in the second link member 62, the pair of arm portions 611 and 612 in the first link member 61 are a pair of pins. It can be inserted together with the parts 65a and 65b. The pivot pins 63 and 63 may be configured separately from the arm portions 611 and 612, and after being assembled in an X shape in a side view, the pivot pins 63 and 63 may be rotatably mounted in the pivot holes 68 and 68.

  A compression coil spring, which is a biasing means 7 described in detail later, can be inserted into the through hole 69 between the pair of arm portions 611 and 612 in the first link member 61 and the through hole 70 in the second link member 62.

  A pair of pin portions at one end of the arm portion of one of the first link member 61 and the second link member 62 is pivotally supported on the bottom plate 32 of the outer case 3 so as to be rotatable only. The pair of pin portions at the other end of the arm portion of the one link member is slidably supported on the lower surface of the base portion 5 facing the bottom plate 32 of the outer case 3. A pair of pin portions at one end of the arm portion of the other link member is pivotally supported on the lower surface of the base portion 5 of the push button member 2 so as to be rotatable only, and a pair of pins at the other end of the arm portion of the other link member The portion is slidably supported by the bottom plate 32 of the outer case 3.

  In the first embodiment (see FIGS. 2 to 8), the pair of pin portions 67 a and 67 b at one end of the arm portions 621 and 622 in the second link member 62 are substantially provided on the surface of the bottom plate 32 in the outer case 3. It is pivotally supported by a pivotal support portion 321 that has a three-quarter cutout circular hole and is detachable and only rotatable (see FIG. 3A). A pair of pin portions 66 a and 66 b at the other ends of the arm portions 621 and 622 in the second link member 62 are slid in the horizontal direction by a hook-shaped locking portion 511 provided on the lower surface of the bottom plate portion 51 of the base portion 5. It is supported so that it can move and rotate and cannot be removed downward (see FIGS. 3A and 8A).

  On the other hand, the pair of pin portions 65a and 65b at one end of the arm portions 611 and 612 in the first link member 61 can only be rotated by the pivot portion 512 provided on the lower surface of the bottom plate portion 51 of the base portion 5 in the push button member 2. It is pivotally supported by. The pair of pin portions 64 a and 64 b at the other end of the arm portions 611 and 612 in the first link member 61 slides in the horizontal direction by the same hook-shaped locking portion 322 provided on the surface of the bottom plate 32 of the outer case 3. Further, it is pivotable and is supported so as not to be disengaged upward (see FIGS. 3A and 8A).

  The compression coil spring which is the urging means 7 includes an upward plate-shaped spring receiver 323 provided on the surface of the bottom plate 32 of the outer case 3 and a downward plate-shaped spring receiver 513 provided on the lower surface of the bottom plate portion 51 of the base 5. (See FIG. 3A, FIG. 3B, FIG. 4A, FIG. 4B, etc.).

  Then, as shown in FIGS. 1D, 3A, and 3B, the locking piece 325 can be bent in the vertical direction through the notch groove 324 in the bottom plate 32 of the outer case 3. A locking claw 326 is integrally provided upward at the tip of the locking piece 325. On the other hand, a regulating groove 71 is formed in a recessed manner on the lower surface of the connecting piece 613 on one side (the side close to the bottom plate 32) of the first link member 61 in the guide support member 6. Since the base 5 is pressed so as to move upward by the urging means 7, the crossing depression angle between the first link member 61 and the second link member 62 in the guide support member 6 increases. When the crossed depression angle is a predetermined maximum value (preset value), the locking claw 326 collides (contacts) with the restriction groove 71, and the first link member 61 does not rotate any more and is pushed. The structure which can regulate the raising position of the button member 2 is employ | adopted. Such a restricting means may be provided in the bottom plate portion 51 in the base portion 5 of the push button member 2.

  According to said structure, in the non-operation state in which the player (operator) is not pushing the front part 21 of the pushbutton member 2, FIG. 3 (a), FIG. 4 (a), FIG. 5 (a), FIG. As shown in a) and FIG. 8A, the push button member 2 is pushed upward by a compression coil spring as the urging means 7. In this state, as described above, the pair of pin portions 65a, 65b, 67a, 67b of the first link member 61 and the second link member 62 in the guide support member 6 are centered on the portions of the pivot portions 512, 321, respectively. The pin portions 64a, 64b, 66a, 66b at the other end move in the horizontal direction at the locations of the hook-shaped locking portions 322, 511. Thus, the push button member 2 rises in a horizontal state.

  When the cross depression angle between the first link member 61 and the second link member 62 is a predetermined maximum value, the position where the upper surface of the front surface portion 21 of the push button member 2 protrudes slightly from the upper surface of the flange portion 312 in the outer case 3 Stop at. Even in this state, it is assumed that a small initial biasing force by the biasing means 7 is acting.

  In this non-operating state, the bottom plate portion 51 of the base portion 5 in the push button member 2 is in a raised position relative to the circuit board 4 at a fixed height position in the outer case 3. Therefore, as shown in FIGS. 3A, 6A, and 8A, the detected object 10 protruding from the upper surface of the bottom plate portion 51 is changed from the light emitting element 11a that is the sensor means 11 to the light receiving element 11b. The detection light in the horizontal direction to is blocked. In this state, an OFF signal is output. Then, a determination element (not shown) provided on the circuit board 4, a connection terminal 41 that is an end of the circuit board 4 and is located outside the lid body 13, and a wiring (not shown) An OFF signal can be sent to an external controller or the like via a signal line).

  When the player (operator) pushes the front surface portion 21, the guide support member 6 is pushed downward against the urging force of the urging means 7 at the bottom plate portion 51 in the base portion 5 of the push button member 2. As a result, the pair of pin portions 65a, 65b, 67a, 67b of the first link member 61 and the second link member 62 rotate around the locations of the pivot portions 512, 321, respectively, and the other pin portion 64a, 64b, 66a, 66b move in the horizontal direction at the locations of hook-shaped locking portions 322, 511. Therefore, the crossing depression angle between the first link member 61 and the second link member 62 becomes small (FIG. 3B, FIG. 4B, FIG. 5B, FIG. 6B and FIG. 8B). reference).

  Accordingly, the push button member 2 is lowered together with the base portion 5, and the front surface portion 21 sinks to substantially the same height as the upper surface of the flange portion 312 of the outer case 3 (FIGS. 3B, 4B, and 5B). FIG. 6 (b) and FIG. 8 (b)). Since the detection target 10 provided on the upper surface of the bottom plate portion 51 of the base portion 5 is positioned below the horizontal detection light path from the light emitting element 11a serving as the sensor means 11 to the light receiving element 11b, the light receiving element 11b Receives detection light and outputs an ON signal. Then, a determination element (not shown) provided on the circuit board 4, a connection terminal 41 that is an end of the circuit board 4 and is located outside the lid body 13, and a wiring (not shown) An ON signal can be sent to an external controller or the like via a signal line).

  By pushing and releasing the push button member 2 as described above, the entire push button member 2 including the base portion 5 is lowered and raised inside the outer case 3. At this time, the push button member is moved by the above-described movement of the first link member 61 and the second link member 62 of the guide support member 6 disposed between the base portion 5 of the push button member 2 and the bottom plate 32 of the outer case 3. 2, the push button member 2 moves up and down (advances and retreats) without tilting, so that the side surfaces of the front surface portion 21 and the base portion 5 are moderately aligned with the inner surface of the side wall portion 31 of the outer case 3. Even if the clearance is left, the push button member 2 can move up and down very lightly (lightly) without being rubbed against each other. Further, since the base portion 5 of the push button member 2 is also lifted and lowered in a substantially horizontal state, there is an effect that the detected body 10 can be accurately blocked and released from the detection light of the sensor means 11.

  In the above-described embodiment, the location where only the pair of pin portions of the first link member 61 and the second link member 62 of the guide support member 6 can be rotated, and the slidable support portion (engagement) of the other pair of pin portions. It is also possible to dispose the portion of the stop portion) in the opposite direction to the illustrated one.

  As a modification of the first embodiment, the sensor means 11 provided on the lower surface of the circuit board 4 has a light emitting element and a light receiving element that are relatively horizontally spaced apart from each other with a downward-opening gap formed in one block body. When the photo interrupter is used, the gap is parallel to the direction in which the circuit board 4 is inserted from the opening 313 of the outer case 3 and is in the vertical direction, and the upper surface of the bottom plate portion 51 of the base 5 is accordingly changed. The object to be detected (shielding plate) 10 ′ protruding from the above is also formed so as to be insertable from below. That is, as shown in FIGS. 3 (a), 3 (b), 4 (a), and 4 (b), the detected body (shielding plate) 10 'has a thickness that allows passage through the gap. It has a vertically long flat plate shape.

  In 2nd Embodiment shown to Fig.9 (a) and FIG.9 (b), the basic form of the pushbutton member 2 and the outer case 3 is the same as 1st Embodiment.
