[0018]
In this pachinko gaming machine 10, a predetermined prepaid card, which is a power card, is inserted into the card insertion slot 1a of the ball lending machine 1 arranged adjacent to the side (of course, cash can be inserted). When a rental ball lending operation, which will be described later, is performed on the front, the lending ball is lent out to the upper ball tray 15 from the payout opening 29, while the backside of the upper ball tray 15 is known depending on the amount of operation of the handle 17 by the player. Is activated to fire a game ball into the game area. For example, when a game ball enters one of the start winning port, the general winning port, and the big winning port on the game board, the gaming ball is paid out from the payout port 29 to the upper ball receiving tray 15. When the game ball passes the passing gate, the normal symbol variation display by the two-color alternate lighting of the normal symbol display LED is executed, and when the variation stops in a predetermined stop mode, the start winning tulip opens. When a game ball is won at the start winning opening, a special symbol variation display game is executed on the symbol display device, and a game is performed in which the opening / closing door of the big winning opening is opened / closed in the front / rear direction according to the stop mode. It is like that. On the other hand, as shown in FIG. 2, the detection means 50 is provided in the right end side in the figure of the base door 11 and the door 12 with a window.
[0019]
When both the base door 11 and the door 12 with a window are closed, the detection means 50 is pressurized from both sides in the door opening / closing direction R and detects the pressurization state. When either one or both are open, the pressure from one or both sides is released, and the pressure release state is detected. The detection means 50 detects the open / close state of the base door 11 and the window. The open / close state of the door 12 can be detected.
[0020]
Specifically, the detection means 50 includes a plunger 51 (movable member) supported by the base door 11 via a bearing sleeve 55 and a mounting plate 56, and an E-ring 57 locked to the rear end portion of the plunger 51. And a washer 58, a spring 52 that is an elastic member contracted between the washer 58 and the mounting plate 56, and a switch that is supported by the window door 12 at a height and a left-right position that can contact the front end of the plunger 51. 53.
[0021]
The plunger 51 has a front end portion whose diameter is larger than the inner diameter of the bearing sleeve 55, and is attached to the rear end portion of the E-ring 57 so as to be separated from the base door 11 in the door opening / closing direction. It can move in the axial direction between (the rear stop position shown in FIG. 4B and FIG. 5) and the other stop position (front stop position shown in FIG. 3). Further, the spring 52 is a biasing means that biases the plunger 51 to one stop position via an E-ring 57 and a washer 58 as shown in FIG. 5, and can cause the plunger 51 to protrude from the base door 11. Further, when the plunger 51 is pressurized forward by closing the base door 11, the spring 52 is compressed accordingly, and the plunger 51 moves to the front side (the other stop position side). Is to be tolerated. The spring 52 may be another elastic body, for example, one having rubber elasticity or an elastic body such as a leaf spring.
[0022]
Further, the switch 53 is a push switch that can be switched ON / OFF, for example, by depressing the operation unit 53a that can be moved in and out, and the plunger 51 that is in contact with the machine frame 100 is shown in FIG. As shown in the figure, when the base door 11 is stopped at the other stop position (immersion position), the operating portion 53a is pushed by the plunger 51 as the window door 12 is closed, and the ON / OFF switching operation is performed. It has become so. Note that the switch 53 incorporates a spring (not shown) that constantly biases the operating portion 53a to the protruding side so as to return the operating portion 53a to a predetermined protruding position.
[0023]
In the opening / closing detection mechanism of the door opening / closing device of this embodiment configured as described above, when both the base door 11 and the window door 12 are closed, the plunger 51 of the detecting means 50 is added from both sides in the door opening / closing direction. While being pressed, the switch 53 is operated in the immersion direction, and the pressure state is detected by the switch 53.
[0024]
On the other hand, when either one or both of the base door 11 and the door 12 with a window are open, the pressure applied to the plunger 51 of the detection means 50 from one side or both sides is released. That is, when the windowed door 12 is opened from the closed state shown in FIG. 6A as shown in FIG. 6B, the operation portion 53a of the switch 53 returns to the protruding state, and the plunger by the spring in the switch 53 While pressing from the front side to 51 is released, the switch 53 is switched to ON or OFF.
[0025]
Further, as shown in FIG. 6C, when the base door 11 is opened, the plunger 51 separated from the machine casing 100 moves to the rear side by the urging force of the spring 52, and the front side and the rear side to the plunger 51. Pressurization from the side is released, and at the same time, the switch 53 is switched to OFF or ON.
[0026]
In the present embodiment, the pressure state in the front-rear direction and the pressure release state with respect to the plunger 51 are detected in this way, so that the base door 11 and the door with window 12 are individually opened and closed by the single detection means 50. The state can be detected, and it is possible to reduce the number of parts and the number of assembly steps. In addition, the plunger 51 is attached to the inner base door 11 and it is only necessary to urge the plunger 51 to one stop position by the spring 52, and the configuration can be simplified. In addition, when the base door 11 is open, the switch 53 and its harness can be prevented from being exposed to the outside.
[0027]
Furthermore, since an elastic member such as a spring 52 is interposed between the base door 11 and the machine casing 100, the opening operation can be easily performed even with the base door 11 which is mounted with a game board or a back mechanism and is heavy. It opens immediately to a certain extent and is easy to operate.
[0028]
Moreover, the impact when the heavy base door 11 is closed can be sufficiently mitigated, and rattling of the base door 11 in the closed state can be suppressed.
[0029]
On the other hand, since the door 12 with a window is lighter than the base door 11, the same effect as the case of the base door 11 can be expected even with a spring in the switch 53.
[0030]
(Other embodiments)
FIG. 7 is a cross-sectional view of an essential part showing a pachinko gaming machine provided with a door opening and closing device according to another embodiment of the present invention.

It is comprised with the load sensor (for example, consisting of a resistor distortion gauge) which is interposed between the member 75 and the to-be-pressurized member 76. Instead of the load sensor, a pressure sensor, a pressure switch, or the like may be used.
[0033]
The load detection element 71 must be able to detect pressure applied from both sides of the door opening / closing direction, but since simple pressure can be applied by the first elastic member 73 and the second elastic member 74, the second door and The configuration on the machine casing 100 side can be simplified.
[0034]
Also in this embodiment, the same effect as the above-described embodiment can be expected. In the present embodiment, the elastic members 73 and 74 are interposed between the door 12 with a window and the base door 11 and between the base door 11 and the machine casing 100, respectively. When the door 12 is opened, the door 12 is immediately opened to the extent that the opening operation is easy, and the operability is good. In addition, the impact when the door is closed can be mitigated by the elastic members 73 and 74, and rattling of the base door 11 and the window door 12 in the closed state can be suppressed.
[0035]

It can also be applied to other gaming machines and devices having a plurality of doors that are opened and closed. In addition, the door here is not limited to a normal door through which an object or a person enters or exits, but may be a plurality of rotating bodies that are supported by a hinge mechanism and are opened and closed to relatively approach and separate on the free end side. Good. Furthermore, the number of doors in the door opening / closing device is not limited to two, and may be three or more doors. For example, a pressurized unit 60 including a plunger 51 and a spushing 52 according to an embodiment is provided in each door, and the switch 53 is turned on / off when any of the doors is opened (the operation unit 53a protrudes). Can be configured.
[0036]
【The invention's effect】
According to the present invention, when both the first door and the second door are closed, the detection means pressurizes from both sides in the door opening / closing direction to detect the pressurization state, and either the first door or the second door is detected. When one or both of them are open, the pressure from one or both sides of the detection means is released and the pressure release state is detected, so that the first door and the first door are detected by a single detection means. Individual open / closed states of the two doors can be detected. As a result, opening / closing detection of a plurality of doors can be performed with a small number of opening / closing detection means, and the number of parts and assembly man-hours can be reduced, thereby reducing the manufacturing cost and improving the reliability.
