Description

  The present invention relates to a push button switch such as a cross button switch that receives various selection inputs from a player in a gaming machine, for example.

  Conventionally, various types of gaming machines have been provided with various effects in order to enhance entertainment, but these effects were automatically generated according to the progress of the game. In recent years, the entertainment of various gaming machines is further improved by accepting the player's selection operation and determination operation for these effects.

  As one of means for accepting various selection inputs of such players, there are push button switches of various shapes. The player can select or determine an effect by pressing the push buttons of these push button switches.

  By the way, when the player presses the push button, static electricity charged to the player may enter the push button switch. Then, when static electricity that has entered the push button switch reaches the control board of the gaming machine, it may cause malfunction or failure of various gaming machines. Thus, for example, a countermeasure against static electricity as disclosed in Patent Document 1 has been proposed for the push button switch.

  In the push button switch described in Patent Document 1, static electricity flows from the push button by connecting an elastic member that holds the push button so that the push button can be pressed and a conductive portion of the operation panel to which the push button switch is attached by a ground member. Can be released to the conductive portion of the operation panel. However, in Patent Document 1, it is necessary to separately provide a conductive portion on the operation panel as well as the ground member not related to the switch function.

JP 2006-66098 A

  In view of the above problems, an object of the present invention is to provide a push button switch that can prevent discharge of static electricity.

The present invention includes at least one push button that allows a player to press down, a substrate that outputs a signal for pressing the push button, and a pressing member that is placed on the substrate and elastically supports the push button so that the push button can protrude and retract. A push button switch configured with a switch case that accommodates each member, wherein the push member is formed of an elastic material having an insulating property, and an elastic support portion that elastically supports the push button, and the substrate The flat surface facing portion facing the push button side surface and the side facing portion facing the side surface of the substrate are integrally formed.
The pressing member can be made of an insulating rubber-based material or an insulating soft resin material.

  According to the present invention, a push button switch that can prevent electrostatic discharge can be configured.

  Specifically, when static electricity is discharged by a player approaching or touching a push button switch, the static electricity flows toward the substrate which is a conductive member so as to crawl the surface of each member. However, the static electricity accumulated in the player is not discharged by extending the distance of the path through which static electricity flows from the push button to the substrate, the so-called creepage distance. For example, in order not to discharge 30 kv of static electricity, the creepage distance is preferably 30 mm or more.

  Therefore, by providing the pressing member with the side facing portion that covers the side surface of the substrate, the path when static electricity flows is transmitted from the push button to the elastic supporting portion and the plane facing portion of the pressing member, and further to the side facing portion. It can be a path that reaches the substrate via the front surface and the back surface.

In other words, by using a path that passes through the front and back surfaces of the side facing portion, it is possible to extend the creeping distance from the push button to the substrate via the pressing member, thereby preventing the discharge of static electricity charged to the player. Can do.
In addition, since the creepage distance can be extended while keeping the linear distance between the push button and the board short, the push button switch can prevent static discharge and can be made thin with a reduced overall length. it can.

  Therefore, the push button switch provided with the side facing portion that covers the side surface of the substrate on the pressing member can prevent electrostatic discharge.

  As an aspect of the present invention, the board is accommodated and held, and has a board mounting member fitted and fixed to the switch case, and an opening and retractable opening of the push button, and fitted and fixed to the switch case. And a button cover, and the switch case can be formed with an intrusion guide portion that allows insertion of the elastic support portion and the push button of the pressing member and guides the push button in and out.

  According to the present invention, the push button switch can more reliably prevent electrostatic discharge.

  Specifically, the substrate can be assembled at a predetermined position of the substrate mounting member. Then, by inserting the elastic support portion of the pressing member placed on the substrate into the intrusion guide portion of the switch case, the pressing member can be assembled to the switch case at an appropriate position and orientation. Furthermore, the pressing member and the board can be assembled at an appropriate position and orientation by fitting the board mounting member and the switch case.

  Moreover, the push button can be assembled at an appropriate position and orientation with respect to the switch case by being inserted into the guide part of the switch case. The button cover and the switch case are fitted, and the button cover can be assembled at an appropriate position and orientation with respect to the switch case by the opening of the button cover.

  By assembling in this way, the pressing member can be assembled in an appropriate position and orientation without providing a special opening such as a positioning hole for determining a mounting position with respect to the substrate or the switch case. For this reason, it is possible to prevent the creepage distance from being shortened by the opening such as the positioning hole. That is, it is possible to more reliably prevent the static electricity accumulated in the player from being discharged. Furthermore, since the pressing member is not provided with an opening such as a positioning hole, durability against pressing can be improved.

  Therefore, the creeping distance can be reliably ensured by a pressing member that does not have an opening such as a positioning hole, so that the push button switch can more reliably prevent electrostatic discharge.

  According to the present invention, it is possible to provide a push button switch that can prevent electrostatic discharge.

Then, a nut 90 is screwed into the case screw thread portion 57 of the switch case 50 from the bottom surface side of the switch main body 21 to fix the switch main body 21 to the lower plate 5.

  In the cross button switch 20 attached to the lower plate 5 in this way, a path when static electricity charged to the player is discharged and static electricity flows into the cross button switch 20 will be described with reference to FIG.

  FIG. 9 is an explanatory diagram for explaining a path when static electricity flows in the cross button switch 20. Further, in FIG. 9, illustration of the lower plate 5, the switch case 50, and the nut 90 is omitted for simplification.

  As shown in FIG. 9, it is assumed that the fingertip F of the charged player approaches or contacts the left button 43, for example. At this time, when static electricity is discharged from the fingertip F of the player, as static electricity flows from the left button 43 to the substrate 70, first, the static electricity crawls the surface of the left button 43 as shown by an arrow L1. And flows from the gap between the button cover 30 and the left button 43 toward the inside of the cross button switch 20.

  Then, the static electricity that has entered the cross button switch 20 through the gap between the button cover 30 and the left button 43 flows further into the button shaft 43b from the collar 43a as indicated by the arrow L2. .

  Furthermore, as indicated by an arrow L3, static electricity flows along the surface of the pressing member 60 and follows a path reaching the substrate body 71 of the substrate 70 that is a conductive member.

  More specifically, static electricity flows toward the plane facing portion 61 so as to crawl the surface of the elastic support portion 63 of the pressing member 60. And the static electricity which reached | attained the plane facing part 61 flows along the upper surface side plane of the plane facing part 61, flows into the side facing part 62, and then flows to the bottom face direction on the outer peripheral surface of the side facing part 62. Further, the static electricity is folded back at the bottom surface side end portion of the side surface facing portion 62, flows along the inner peripheral surface of the side surface facing portion 62 toward the substrate 70, and follows a path reaching the substrate body 71 of the substrate 70.

  As described above, the cross button switch 20 having the above-described configuration capable of extending the path when static electricity flows can prevent electrostatic discharge.

  Specifically, when the charged fingertip F of the player is discharged close to or in contact with the cross button switch 20, static electricity flows toward the substrate 70, which is a conductive member, so as to crawl the surface of each member. . However, the accumulated static electricity is not discharged by extending the creeping distance from the cross button 40 to the substrate 70.

  Therefore, by providing the pressing member 60 with the side facing portion 62, the path when static electricity flows is transmitted from the cross button 40 to the elastic support portion 63 and the plane facing portion 61 of the pressing member 60, and further to the side facing portion. A path reaching the substrate 70 via the outer peripheral surface and the inner peripheral surface of 62 can be used.

  That is, a creeping distance from the cross button 40 to the substrate 70 via the pressing member 60 (arrows L1, L2, and L3 in FIG. 9) is set as a path that passes through the outer peripheral surface and the inner peripheral surface of the side facing portion 62. ) Can be extended for a long time, so that the discharge of static electricity charged to the player can be prevented.

  Furthermore, since only the creepage distance can be extended while the linear distance between the cross button 40 and the substrate 70 is suppressed, the cross button switch 20 can prevent discharge of static electricity and can be reduced in thickness and reduced in length. can do.

  Therefore, the cross button switch 20 having the pressing member 60 provided with the side facing portion 62 that covers the side surface of the substrate 70 can prevent electrostatic discharge.

  In addition, the board 70 includes a board attachment member 80 that fits and fixes to the switch case 50 and a button cover 30 that fits and fixes to the switch case 50, and the switch case 50 includes an elastic support portion for the pressing member 60. 63 and the cross button 40 are allowed to be inserted, and the cross-button switch 20 can more reliably prevent the discharge of static electricity by forming the guide tube portion 54 that guides the cross-button 40.

  Specifically, the substrate 70 can be assembled to the substrate attachment portion 82 of the substrate attachment member 80. Then, by inserting the elastic support portion 63 of the pressing member 60 placed on the substrate 70 into the guide tube portion 54 of the switch case 50, the pressing member 60 is assembled to the switch case 50 at an appropriate position and orientation. be able to. Furthermore, when the board mounting member 80 and the switch case 50 are fitted, the pressing member 60 and the board 70 can be assembled at an appropriate position and orientation.

  Further, the cross button 40 can be assembled to the switch case 50 at an appropriate position and orientation by being inserted into the guide tube portion 54 of the switch case 50. Then, the button cover 30 and the switch case 50 are fitted, and the button cover 30 can be assembled to the switch case 50 at an appropriate position and orientation by the opening X of the button cover 30.

  By assembling each member in this way, the pressing member 60 can be assembled at an appropriate position and orientation without providing a special opening such as a positioning hole for determining the mounting position with respect to the substrate 70 or the switch case 50. it can. For this reason, it is possible to prevent the creepage distance from being shortened by the opening such as the positioning hole. That is, it is possible to more reliably prevent the static electricity accumulated in the player from being discharged. Furthermore, since the pressing member 60 is not provided with a special opening such as a positioning hole, durability against pressing can be improved.

  Therefore, the creeping distance can be reliably ensured by the pressing member 60 that is not provided with an opening such as a positioning hole, so that the cross button switch 20 can more reliably prevent electrostatic discharge.

  Further, since the cross button 40 and the elastic support portion 63 of the pressing member 60 are inserted into the guide tube portion 54, when the player presses the cross button 40, the cross button 40 can smoothly appear and disappear.

  Further, the pressing member 60 can be supported by inserting the supporting protrusion 64 of the pressing member 60 into the protruding portion 59 of the switch case 50. Thereby, when the player presses the cross button 40, it is possible to prevent the elastic support portion 63 of the pressing member 60 from falling due to a change in balance.

  In the present embodiment, the four-way cross button 40 is used. However, the present invention is not limited to this, and an appropriate number of buttons may be used depending on the application. For example, a configuration in which an up / down or left / right two-way button, one button, or a combination of a two-way or four-way button and one button may be used.
