Embodiments of the present invention will be described below with reference to the drawings.
A button switch (hereinafter simply referred to as “switch 1”) according to an embodiment of the present invention will be described with reference to FIGS.
The perspective view of FIG. 1A shows an enlarged view of a portion where the switch 1 is incorporated in the operation panel of the gaming machine. As described above, the switch 1 exposes the first button 10 and the second button 20 arranged on the upper surface of the housing 30 from the panel surface 2 and connects to the external wiring 3 at a position that cannot be seen under the panel surface 2. Has been.
With this configuration, the switch 1 is used to operate the game machine when the player pushes the first button 10 and the second button 20.

The outer periphery of the exposed portion of the upper surface of the housing 30 has an elliptical shape, and the illuminated first push face plate 11 is circular and has a larger area than the second push face 21 (see FIG. 2). .
By configuring the exposed surface of the switch 1 in this manner, the first button 10 and the second button 20 are geometrically arranged in a small area and in close contact with each other, and the housing 30 for housing them is arranged. The occupied area inside the panel surface 2 can be reduced, resulting in space saving.

The external wiring 3 has a distal end portion connected to the switch 1 and a proximal end portion (not shown) connected to a control device (not shown) of the game machine to supply power for illuminating the first button 10. A signal indicating the on / off state of the first button 10 and the second button 20 is transmitted to the control device.
By illuminating the first button 10 in this way, even if the buttons 10 and 20 of the switch 1 are configured to have a small area, an erroneous operation with other switches (not shown) is prevented, and an operation is suggested to the player. More decorative effects. In addition, although the illumination type button switch 1 is used, only one external wiring 3 is required, thereby improving the maintainability of the game machine.

The perspective view of FIG. 1B shows a state where the switch 1 is removed from the panel surface 2.
As shown in the figure, the switch 1 has a housing 30 engaged with the opening 2 a of the panel surface 2 and fixed by a fastening member 50. The switch 1 configured as described above can be easily attached to and detached from the panel surface 2 and the maintainability of the game machine is improved.

  The housing 30 constitutes the main body of the switch 1, and is divided into a flange part 31, a storage part 32, a threaded surface 33, and an electrical part 40 in appearance. The housing 30 configured in this manner accommodates the first button 10 and the second button 20 in the interior thereof, so that these exposed surfaces (push surfaces) are pushed by the player's fingers. Support bullets.

The flange portion 31 is provided in a flange shape on the outer periphery of the upper surface of the housing 30 so as to lock the opening 2a of the panel surface 2 from the upper side in the drawing.
As will be described in detail later, the storage portion 32 stores the first button 10 and the second button 20 in a displaceable manner therein. Further, in the storage portion 32, the horizontal cross section of the outer periphery of the portion connected to the heel part 31 is substantially coincident with the opening 2a of the panel surface 2, and the horizontal cross section of the other portion is narrower than the opening 2a. Yes. Thereby, the switch 1 can be engaged only by inserting from the outer side of the panel surface 2 toward the opening 2a.

Further, a threaded surface 33 is provided on the side peripheral surface of the storage portion 32, and the switch 1 is fixed by sandwiching the opening 2a with the flange portion 31 when the nut 52 is inserted.
Thus, by turning the nut 52 in the forward / reverse direction, the switch 1 inserted in the panel surface 2 can be easily fixed / released, which contributes to improvement in maintainability of the switch 1.

  The electrical unit 40 is formed on the lower surface of the housing 30, and a light source 44 (see FIG. 2) that detects the on / off state of each of the first button 10 and the second button 20 and illuminates the first button 10. This is a portion where light is emitted and the connection terminal 4 provided at the tip of the external wiring 3 is detachably connected. By configuring the electrical component 40 in this way, electronic components and electrical circuit systems are integrated, contributing to space saving and improvement in maintainability.

The fastening member 50 includes a nut 52 and a pedestal 51.
The pedestal 51 is interposed between the panel surface 2 and the nut 52, and is provided with a pair of elastic contact pieces 53 so as to face each other at a position where the major axis of the ellipse in a plan view intersects with the peripheral edge thereof. Yes.
As shown in a side view of the pedestal 51 in FIG. 1 (c), the elastic contact piece 53 has a side end formed by two notches provided on the periphery of the pedestal 51 facing the panel surface 2. In addition, the tip facing upward is formed higher than the peripheral edge so as to abut against the panel surface 2.

  By configuring the pedestal 51 in this way, the elastic contact piece 53 that contacts the panel surface 2 is elastically deformed by tightening the nut 52, and the stress generated by this elastic deformation is applied to the nut 52 and the threaded surface 33. The reverse rotation of the nut 52 is prevented by acting. Thereby, even if a player repeatedly strikes the switch 1, the switch 1 is less likely to be loosely fixed to the panel surface 2 and nevertheless the ease of attachment / detachment is not sacrificed.

  Further, in the process of tightening the nut 52 to fix the switch 1 to the panel surface 2, the state in which the tip of the elastic contact piece 53 is lifted from the panel surface 2 is changed to the contact state, and the peripheral edge of the pedestal 51 is further changed. When shifting to a state in which the entirety abuts against the panel surface 2, the rotational torque of the nut 52 changes stepwise. As a result, in an actual game machine, the lower part of the panel surface 2 of the switch 1 often becomes a blind spot, but the operator can touch the panel surface of the switch 1 with the tactile sensation of the fingertip that rotates the nut 52 without visual confirmation. 2 can be confirmed. This contributes to improving the maintainability of the game machine.

In the present invention, the method of fixing the switch 1 to the panel surface 2 is not limited to that achieved by the cooperation of the fastening member 50 and the threaded surface 33 as shown in FIG. The switch fixing method applied to the current game machine can be adopted as appropriate.
For example, although not shown in the drawing, a protrusion that protrudes and protrudes elastically is provided on the side peripheral surface of the storage portion 32 in FIG. 1B, and at the same time the switch 1 is inserted into the opening 2a, this protrusion is in the drawing of the opening 2a.

Returning to FIG. 2, the description will be continued.
The electrical unit 40 includes a substrate 45, a holding member 46, a holding piece 34 extending from the storage unit 32, and a light shielding wall 75 (see FIGS. 3B and 3C).

The holding pieces 34, 34 are a pair of (two) curved surface pieces that extend from the storage portion 32 toward the bottom surface of the housing 30 and are opposed to each other so as to have a notch 35.
The substrate 45 is formed so that the outer peripheral shape is inscribed in the holding piece 34, and the protruding portion 48 is engaged with the notch 35 to fix the relative position in the rotation direction with respect to the housing 30. Further, the substrate 45 includes a light source 44, a first detector 41, a second detector 42, and a connector 43 on the substrate 45.

The first detector 41 is a U-shaped electronic component in which two rods stand upright in parallel, and is soldered directly to a printed wiring on the substrate 45. The first detector 41 is in an off state in which a light beam emitted from a light emitting element (not shown) arranged on one rod is received by a light receiving element (not shown) arranged on the other rod; A signal corresponding to an on state in which a light beam is blocked with a shutter interposed between the rods is output.
The first detector 41 configured as described above detects the on / off state of the first button 10 in correspondence with the detection / non-detection of the first shutter 68 provided on the moving element 60 that is displaced in the vertical direction. To do.

The second detector 42 is also the same electronic component as the first detector 41, and the second shutter 20 provided on the guide piece 23 is made to detect / not detect and the second button 20 is turned on / off. An off state is detected.
The light source 44 is also an electronic component that is directly soldered to the printed wiring on the substrate 45 and illuminates the first push face plate 11.

As shown in FIGS. 3B and 3C, the light shielding wall 75 is a partition wall that partitions the first storage chamber 70 and the second storage chamber 80 in the housing 30 further extending toward the bottom. The front end abuts on the substrate 45 and partitions the space between the light source 44 and the second detector 42.
By configuring the light shielding wall 75 in this manner, the substrate 45 is stably fixed to the housing 30 and is also blocked by the moving element 60 when the first button 10 is switched between the on state and the off state. The light from the flickering light source 44 does not reach the second detector 42. Thereby, the reliability of the detection operation of the ON state / OFF state of the second button 20 is improved.

  As described above, the main body portion of the switch 1 is entirely configured by fitting integrally molded products, including the casing 30, the first button 10, the second button 20, and the like, which are its component parts. That is, it does not include a joined portion obtained by joining two or more members separated separately by an adhesive or brazing (excluding electronic components). In general, the durability of such a joint portion decreases. However, since the switch 1 of the present embodiment has a structure that does not include such a joint portion, it can be said that the durability is high. Furthermore, since the component parts such as the fitted housing, the first button, and the second button can be reversibly disassembled, a button switch excellent in maintainability is provided. In addition, even in a game arcade where a large number of game machines to which the switch 1 of the present invention is attached are installed, the switch 1 can be finely disassembled in element parts, so that repairs can be easily performed in parts. Therefore, the number of repair parts stocked can be reduced.

  Next, the operation of the switch 1 will be described with reference to FIGS. Here, FIG. 3C is a longitudinal sectional view in which two buttons are both in the OFF state in the XX section of FIG. 3A, and FIG. 3D is a diagram in which both the buttons are in the ON state. FIG.

(Operation of the first button)
First, in the off state where the first push face plate 11 is not bushed as shown in FIG. 3 (c), the first elastic member 14 is elastic and the first and second spring contact surfaces 66 are in contact with both ends. A stress acts on the guide piece 72 in a direction to widen these intervals. Then, the acting force of the first resilient member 14 is canceled by the reaction force of the first locking portion 73 with which the first locking piece 64 abuts, and the first push face plate 11 slightly protrudes from the flange portion 31. Still at position. In this state, the first detector 41 does not detect the first shutter 68 and outputs an off-state signal.

Next, in the ON state shown in FIG. 3 (d), in which the first push face plate 11 is bushed with the fingertips in the direction opposite to the impact of the first impact member 14, the first push face plate 11 The acting force that acts is canceled out by the reaction force of the first abutment surface 71 against which the abutment rod 63 abuts, and the first push face plate 11 stops at a position where the surface of the heel portion 31 is aligned. In this state, the first detector 41 detects the first shutter 68 and outputs an on-state signal.
In addition, the luminous intensity of the first push face plate 11 illuminated by the light emission of the light source 44 varies greatly in the relative positional relationship between the light source 44, the reflective face 61, and the first push face plate 11 regardless of whether the light intensity is on or off. Not so stable.

(Operation of the second button)
First, in the off state in which the second push surface 21 is not bushed as shown in FIG. 3 (c), the second elastic member 25 is elastic and the back surface of the second push surface 21 that is in contact with both ends thereof. A stress acts on the bottom of the spring accommodating hole 85 (FIG. 3A) in a direction to widen these intervals. Then, the acting force of the second resilient member 25 is canceled by the reaction force of the second locking portion 82 with which the second locking piece 22 abuts, and the second push surface 21 is flush with the flange portion 31. Stand still at the position. In this state, the second detector 42 does not detect the second shutter 24 and outputs an off-state signal.

Next, in the ON state shown in FIG. 3 (d) in which the second push surface 21 is bushed with the fingertip in the direction opposite to that of the second elastic member 25, the second push surface 21 The acting force of the acting fingertip is canceled by the reaction force of the second abutting surface 81 against which the back surface of the second push surface 21 abuts, and the second push surface 21 stops at a position slightly depressed from the heel part 31. In this state, the second detector 42 detects the second shutter 24 and outputs an on-state signal.
Further, the light emitted from the light source 44 is shielded by the light shielding wall 75 and does not reach the second detector 42. Thereby, the second detector 42 does not malfunction even if the light leaking from the light source 44 flickers as the adjacent first push face plate 11 repeats the ON state / OFF state.

  In the above description, the button switch 1 has been illustrated as an example in which two buttons (the first button 10 and the second button 20) are housed in one housing 30, but the present invention is not limited to this. The case where three or more buttons are stored in one housing 30 is also included.
