Description

  The present invention provides a pachinko machine in which a glass door through which a game board can be visually observed is supported so as to be openable and closable with respect to the main body frame, and the main body frame is supported so as to be openable and closable with respect to the machine frame. The present invention relates to a door opening / closing detection device applied to a pachinko machine.

  In general, a pachinko machine has a vertical rectangular machine frame (outer frame) installed in an island facility of a game arcade, and a main body frame (front surface) attached to the machine frame in a door-like manner via a hinge portion. Frame), a game board housed inside the main body frame, and a glass door attached to the front of the main body frame via another hinge portion so as to be opened and closed, and formed at the center of the glass door A transparent plate that allows viewing of the game board is attached to the opening. A liquid crystal display device, which is one of the electrical components, is attached to the back of the main body frame, and a control processing device (control board) that controls the game as other electrical components, and a prize ball by a prize ball payout device A payout board for controlling payout, a power supply board for supplying power to each part, an external terminal board for outputting various information relating to the pachinko machine such as the number of winning balls and the open / closed state of the door to the hall computer of the game hall are attached.

  In a pachinko machine that is roughly configured in this way, usually a detection switch is provided on each of the back and front of the main frame to prevent the player from opening the glass door and main frame without permission. The open / close state of the main body frame relative to the machine frame and the open / close state of the glass door relative to the main body frame are individually detected based on the output signals of these two detection switches. However, since the open / closed state of the glass door and the body frame must be detected using separate detection switches, the installation space for these detection switches becomes large, and the wires that electrically connect each detection switch to the external terminal board There is a problem that the routing of the harnesses becomes complicated, resulting in high cost and reduced reliability.

  Therefore, conventionally, when both the glass door and the main body frame are closed, pressure is applied from both sides in the door opening and closing direction to detect the pressure state, and either one or both of the glass door and the main body frame are opened. A detection means for detecting the pressure release state by releasing the pressure from one side or both sides, and detecting the open / close state of the glass door and the open / close state of the main body frame by the detection means. A machine has been proposed (see, for example, Patent Document 1). This detection means includes a mounting plate fixed to the free end opposite to the hinge portion in the main body frame, a plunger supported by the mounting plate so as to be movable in the front-rear direction via a bearing sleeve, and elastically moving the plunger backward. It consists of an urging spring and a push switch attached to the back of the glass door at a position where it can abut against the front end of the plunger. It is a unitized part.

  In a pachinko machine using such a detection means, when both the glass door and the main body frame are closed, the plunger protrudes forward against the biasing force of the spring by the rear end abutting against the machine frame. Therefore, the actuator of the push switch is pushed in contact with the front end of the plunger, and either an on / off signal is output from the push switch. On the other hand, when the main body frame is opened with respect to the machine frame, the plunger moves rearward due to the urging force of the spring when the rear end thereof is separated from the machine frame, and accordingly, the actuator is moved to the return spring built in the push switch. Since the projection is energized, an on / off switching signal is output from the push switch. In addition, when the glass door is opened with respect to the closed body frame, the actuator moves away from the front end of the plunger protruding forward, and in this case as well, the actuator is biased by the return spring built in the push switch. An on / off switching signal is output from the push switch. Therefore, it is possible to detect individual open / close states of the glass door and the main body frame by using a single detection means including a plunger, a push switch, and the like.

Japanese Patent No. 4159724

  However, in the conventional pachinko machine disclosed in Patent Document 1, a unit part integrated with a mounting plate incorporating a plunger, a spring, and the like is attached to the free end side of the main body frame, and the plunger is attached to the free end side of the glass door. Because the detection means is configured by attaching a push switch that can be moved toward and away from the front end, the parts installation space for the detection means is distributed to both the main body frame and the glass door, and unit parts and push switches can be installed individually. There was a problem that the work of attaching to the position was troublesome. In addition, the push switch, which is a detection switch, must be electrically connected to the external terminal board provided on the back side of the body frame using a wire harness, but the push switch is installed on the free end side of the glass door. Therefore, it is necessary to route the wire harnesses from the free end side of the glass door to the external terminal board of the main body frame via the hinge part on the base end side, and the routing route of the wire harnesses becomes very complicated. There was also a problem of end.

  The present invention has been made in view of the actual situation of the prior art, and the first object thereof is to individually detect the open / closed state of the glass door and the main body frame by a single open / close detection means provided on the main body frame.

Hereinafter, the operation of the door opening / closing detection device 30 will be described mainly with reference to FIGS. 7 and 8.

  In the pachinko machine P according to the present embodiment, since the main body frame 2 is closed with respect to the machine frame 1 and the glass door 3 is closed with respect to the main body frame 2 in a normal state, FIG. ), The operating blade pieces 32b and 33b of the lower rotating lever 32 and the upper rotating lever 33 of the door opening / closing detection device 30 are in contact with the front surface of the machine frame 1 and the rear surface of the glass door 3, respectively. 32b and 33b stop at a position where they overlap each other against the urging force of the torsion coil spring 34 (this is referred to as an initial position). In this case, as shown in FIG. 8 (a), the inclined surfaces 32c and 33c of the lower rotary lever 32 and the upper rotary lever 33 are in contact with each other with their topmost parts close to each other, and the upper first position Since the driving lever 35b of the detection switch 35 is pressed by the operating blade piece 33b of the upper rotation lever 33 that has moved to the position, either the on / off signal indicating the door closed state is output from the detection switch 35.

  As shown in FIG. 7B, when the main body frame 2 is opened with respect to the machine frame 1 while rotating about the first hinge mechanism, the operating blade piece 32b hits the front surface of the machine frame 1 until then. The lower rotating lever 32 that has been in contact with the torsion coil spring 34 is rotated in the direction of the arrow Q1 by the urging force of the torsion coil spring 34, and the lower rotating lever 32 stops when the operating blade piece 32b comes into contact with one stopper protrusion 31c. When the lower rotating lever 32 rotates by a predetermined angle (about 90 degrees) from the initial position in this way, the inclined surface 32c of the lower rotating lever 32 is inclined to the upper rotating lever 33 as shown in FIG. It rotates about 90 degrees with respect to the surface 33c, and both the inclined surfaces 32c, 33c are displaced to a position where the top of each other is slidably contacted with the flat portion of the other side. Move down to about the second position by about half. As a result, the operating blade piece 33b of the upper rotating lever 33 moves downward with respect to the detection switch 35, so that the pressing of the drive lever 35b by the operating blade piece 33b is released, the detection switch 35 is switched, and the detection switch 35 is switched. Outputs a switching signal indicating the door open state.

  Further, as shown in FIG. 7C, when the glass door 3 is opened with respect to the main body frame 2 while rotating around the second hinge mechanism, the operating blade piece 33b is moved to the back of the glass door 3 until then. The upper rotary lever 33 stops when the upper rotating lever 33 that has been in contact with the rotation of the torsion coil spring 34 rotates in the direction of the arrow Q2 by the biasing force of the torsion coil spring 34 and the operating blade piece 33b comes into contact with the other stopper projection 31d. When the upper rotation lever 33 rotates by a predetermined angle (about 90 degrees) from the initial position in this way, the inclined surface 33c of the upper rotation lever 33 becomes the inclined surface of the lower rotation lever 32 as shown in FIG. Rotate about 90 degrees with respect to 32c, and both inclined surfaces 32c and 33c are displaced to a position where the top of each other is in sliding contact with the flat portion of the other side. Move down to about the second position by about half the size. As a result, the operating blade piece 33b of the upper rotating lever 33 moves downward with respect to the detection switch 35, so that the pressing of the drive lever 35b by the operating blade piece 33b is released, the detection switch 35 is switched, and the detection switch 35 is switched. Outputs a switching signal indicating the door open state.

  As described above, in the pachinko machine P according to the present embodiment, the door opening / closing detection device 30 capable of detecting the opening operation of the main body frame 2 with respect to the machine frame 1 and the opening operation of the glass door 3 with respect to the main body frame 2 is the main body. The door opening / closing detection device 30 installed in the frame 2 includes a base member 31 having a support shaft 31a extending in the vertical direction, a lower rotation lever 32 supported by the support shaft 31a so as to be rotatable and vertically movable, and The upper rotating lever 33, the torsion coil spring 34 that urges both the rotating levers 32 and 33 toward the machine frame 1 and the glass door 3 in opposite directions and the vertical movement of the upper rotating lever 33 are switched. And the inclined surfaces 32c and 33c for converting the relative rotational motion of the lower rotary lever 32 and the upper rotary lever 33 into the vertical motion. Therefore, the open / closed state of the glass door 3 and the main body frame 2 can be individually detected by a single door open / close detection device 30 installed in the main body frame 2, and between the detection switch 35 and the external terminal board 22. The wire harnesses for connecting the cables can be easily routed only on the main body frame 2 side. Further, the door opening / closing detection device 30 can be handled as one unit component by incorporating the rotary levers 32, 33, the torsion coil spring 34, and the detection switch 35 into the base member 31 to form a unit. In addition to simplifying the parts management and parts transportation before attaching to the pachinko machine, the attaching work to the pachinko machine P can be easily performed.

  In the above embodiment, the inclined surfaces 32c and 33c are formed on the opposing surfaces of the lower rotating lever 32 and the upper rotating lever 33, but either one of the inclined surfaces is changed to a protrusion, and this protrusion You may make it contact | abut to the other party inclined surface. In addition, the tapered shape of the inclined surfaces 32c and 33c can be changed as appropriate. For example, the inclined surfaces 32c and 33c can have a continuous tapered shape without a flat portion in the middle, or three at every 120 degrees on the upper end surface of the lower rotation lever 32. The inclined surface 32 c may be formed continuously, and the same inclined surface 33 c may be formed on the lower end surface of the upper rotation lever 33.

  In the above embodiment, the detection switch 35 called a micro switch is operated by the vertical movement of the upper rotation lever 33. However, other detection switches such as a seesaw switch and a push switch may be used instead of the micro switch. It is also possible to use an optical or magnetic detection element instead of the detection switch.

  Moreover, although the case where the door opening / closing detection device 30 is attached to the lower right corner of the main body frame 2 has been described in the above embodiment, the door opening / closing detection device 30 is installed anywhere on the free end side of the main body frame 2. For example, the door opening / closing detection device 30 can be attached to the upper right corner of the main body frame 2 to shorten the routing route of the wire harnesses.
