Abstract

<P>PROBLEM TO BE SOLVED: To accurately detect the opened/closed state of an opening/closing body opened/closed with respect to a base body, with low-cost constitution. <P>SOLUTION: In a Pachinko machine 10, the open side end of an inner frame 14 is provided with an opening/closing detecting switch 104 for detecting the opened/closed state of the inner frame 14, and an outer frame 12 is provided with an opening/closing detecting part 120 corresponding to the opening/closing detecting switch 104. Since a connection distance between the opening/closing detecting switch 104 and a base mounted to the inner frame 14 is shortened, wiring handling of a lead wire of the opening/closing detecting switch and connection work of a connector are facilitated to cut down a manufacturing cost. Further, the stroke amount of a push button 108 to the opening/closing angle of the inner frame 14 is increased to enlarge a margin of a detection range of the opening/closing detecting switch 104. The open state can thereby be accurately detected even when the inner frame 14 is opened only slightly. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  The present invention relates to a gaming machine provided with detection means for detecting an open / closed state of an open / close body provided on a base body so as to be openable / closable.

In gaming machines such as pachinko machines, the open / close state of the open / close body is detected in order to prevent the open / close body such as the inner frame (front frame) provided on the base body such as the outer frame from being opened and closed illegally. There is a technique in which a switch (limit switch) as a detecting means is attached to a base and the switch is operated (released / pressed) by opening and closing an opening / closing body (see, for example, Patent Document 1).
JP 2000-325636 A

  However, in the configuration of the above technique, in order to connect the lead wire of the switch attached to the base to the substrate of the opening / closing body, etc., it must be routed to the connection destination via the rotation support shaft side of the opening / closing body, The wiring route of the lead wire becomes complicated and the wiring distance is extended, so that the wiring process becomes complicated. In addition, by providing a switch, which is an electronic component, on the base, inspection items in the unit, for example, an operation check of the switch, and the like increase, resulting in an increase in manufacturing cost.

  On the other hand, if the switch is arranged near the rotation support shaft of the opening / closing body in order to shorten the wiring distance of the lead wire, the stroke amount of the switch with respect to the opening / closing angle of the opening / closing body is reduced, and the detection range margin is reduced. For this reason, for example, when the opening / closing body is slightly opened, there is a possibility that the release amount of the switch becomes small and the open state cannot be detected correctly.

  In view of the above facts, an object of the present invention is to provide a gaming machine capable of accurately detecting an open / closed state of an opening / closing body opened / closed with respect to a base body with an inexpensive configuration.

  In order to solve the above-mentioned problem, an invention according to claim 1 is provided with a base, an opening / closing body provided on the base so as to be openable and closable, and an opening side end of the opening / closing body. And a detection unit that detects an open / close state, and a determination unit that is provided in the open / close body and is connected to the detection unit and determines an open / close state of the open / close body based on detection information from the detection unit. Yes.

  According to the first aspect of the present invention, in order to prevent the opening / closing body from being illegally opened with respect to the base body, a detecting means for detecting the opening / closing state of the opening / closing body is provided at the open side end of the opening / closing body, The determination means provided on the body is connected to the detection means, and the determination means is configured to determine the open / closed state of the opening / closing body based on detection information from the detection means.

  As described above, by providing the opening / closing body with the detection means for detecting the open / closed state of the opening / closing body, the connection distance between the detection means and the determination means is shortened, so that wiring processing and connection work are facilitated. In addition, the number of inspection items of the detection means in the manufacturing process can be reduced as compared with the configuration in which the detection means is provided on the base. Thereby, manufacturing cost can be suppressed and an inexpensive configuration can be obtained.

  In addition, by providing the detection means at the open end of the opening / closing body, the margin of the detection range of the detection means with respect to the opening / closing angle of the opening / closing body is increased, for example, even when the opening / closing body is opened slightly. Can be detected accurately.

  According to a second aspect of the present invention, in the gaming machine according to the first aspect, the detection means is a switch that detects an open / closed state of the opening / closing body by pressing and releasing the pressing portion against the base body. The base has an impact absorbing means for absorbing an impact acting on the pressing portion when the opening / closing body is closed.

  In the invention according to claim 2, the switch as the detecting means detects the open / closed state of the opening / closing body by the pressing portion being pressed and released from the base. In such a press-type switch, for example, when the pressing portion is pressed against the high-rigidity portion of the base body, an impact is applied to the pressing portion every time the opening / closing body is closed, and there is a concern that the durability may be lowered. Is done. In addition, the open side end with a large distance from the rotation support shaft is likely to have a greater impact force when the opening / closing body is closed than the base end side end with a small distance from the rotation support shaft. If it is arranged at the open end, durability tends to be disadvantageous.

  On the other hand, if it is said structure, since the impact which acts on a press part at the time of closure of an opening-and-closing body will be absorbed by the impact-absorbing means which a base | substrate closes, durability of a switch can be prevented. In addition, the life can be extended even in the configuration in which the switch is arranged at the open end of the opening / closing body.

  According to the gaming machine of the present invention, the open / closed state of the opening / closing body that is opened / closed with respect to the base body can be accurately detected with an inexpensive configuration.

  Hereinafter, a gaming machine according to an embodiment of the present invention will be described with reference to the drawings.

(Inner frame open / close detection mechanism)
Next, in the pachinko machine 10 described above, an open / close detection mechanism according to the present embodiment that detects the open / closed state of the inner frame 14 as an open / close body provided on the outer frame 12 serving as a base body so as to be opened / closed will be described.

  5 to 7 show an open / close detection mechanism 100 according to the present embodiment provided on the inner frame 14 and the outer frame 12 of the pachinko machine 10.

  As shown in FIG. 5, the inner frame 14 is formed with a switch mounting opening 102 in the vicinity of the lower end on the right side when viewed from the front side. The switch mounting opening 102 is formed on the back side of the switch mounting opening 102. As shown in FIGS. 6 and 7, an open / close detection switch 104 is attached.

  The open / close detection switch 104 according to the present embodiment is a general-purpose push switch in which a push-type push button 108 is assembled to the switch body 106. The switch body 106 is in an attitude in which the push button 108 faces backward. It is attached to the back surface of the frame 14. As shown in FIG. 2, the lead wire 110 of the open / close detection switch 104 is routed upward along the back surface of the inner frame 14, and the connector 112 provided at the tip is substantially at the center of the back surface of the inner frame 14. Is connected to the connector 116 of the main control board 114 provided on the main control board 114.

  When the pachinko machine 10 is installed in the pachinko hall island facility, the main control board 114 is electrically connected to the hall computer and transmits various information to the hall computer. The information transmitted to the hall computer includes information indicating the open / close state of the inner frame 14 based on the electrical signal (ON / OFF signal) input from the open / close detection switch 104.

  On the other hand, in the outer frame 12, an opening / closing detection unit 120 is provided at a predetermined position of the lower decoration 16 corresponding to the opening / closing detection switch 104.

  The open / close detection unit 120 is a rectangular plate-like body that is erected on the rear right side of the upper surface of the lower decoration 16, and is provided integrally with the lower decoration 16, and has an upper edge and left and right side edges. It is reinforced by the circumferential rib 122 formed continuously.

  A metal leaf spring 124 made of stainless alloy (SUS) or the like is attached to the front surface of the open / close detection unit 120. The leaf spring 124 includes a fixing portion 126 fixed to the open / close detection portion 120 and a free end portion 128 bent in a substantially V shape with respect to the fixing portion 126 and elastically deformable in the front-rear direction. The free end 128 is disposed so as to contact the push button 108 of the open / close detection switch 104.

  Next, the operation of this embodiment will be described.

  In the pachinko machine 10 according to the present embodiment, when the opened inner frame 14 as shown in FIGS. 5 and 6 is closed to the outer frame 12, the inner frame 14 approaching the outer frame 12 hits the outer frame 12. A little before, the push button 108 of the open / close detection switch 104 contacts the free end 128 of the leaf spring 124 provided in the open / close detection unit 120. Then, when the inner frame 14 is abutted against the outer frame 12 and closed, the free end 128 of the leaf spring 124 is elastically deformed backward as shown in FIG. The push button 108 is pushed into the switch body 106, and the open / close detection switch 104 is turned on.

  In this switch ON state, an ON signal is input from the open / close detection switch 104 to the main control board 114, and the main control board 114 determines that the inner frame 14 is closed and transmits the information to the hall computer.

  When the inner frame 14 is released from the closed state, the push button 108 is released from the free end 128 of the leaf spring 124, the push button 108 protrudes from the switch body 106, and the open / close detection switch 104 is turned off. It becomes.

  In this switch OFF state, an OFF signal is input from the open / close detection switch 104 to the main control board 114, and the main control board 114 determines that the inner frame 14 is open and transmits the information to the hall computer.

  As a result, the open / closed state of the inner frame 14 in the pachinko machine 10 can be grasped on the hall side, and the inner frame 14 can be prevented from being opened by an unauthorized act and the pachinko machine 10 can be prevented from being illegally operated. .

  In the present embodiment, since the opening / closing detection switch 104 for detecting the opening / closing state of the inner frame 14 is provided in the inner frame 14, the connection distance between the opening / closing detection switch 104 and the main control board 114 is shortened, and the lead wire 110. Wiring processing and connection work of the connector 112 are facilitated. Further, for example, compared with the case where the open / close detection switch 104 is provided in the outer frame 12, the inspection items of the open / close detection switch 104 in the manufacturing process can be reduced. Thereby, the manufacturing cost of the pachinko machine 10 is suppressed, and the opening / closing detection mechanism 100 having an inexpensive configuration can be realized.

  Further, the opening / closing detection switch 104 is provided at the opening side end of the inner frame 14, that is, at a position farthest from the hinge portions 18 and 20 constituting the rotation support shaft of the inner frame 14, thereby opening and closing the inner frame 14. The stroke amount of the push button 108 with respect to the angle increases, and the margin of the detection range by the open / close detection switch 104 increases. Thereby, for example, even when the inner frame 14 is opened a little, the open state can be accurately detected.

  In particular, in the present embodiment, the open / close detection switch 104 is disposed near the lower end of the inner frame 14 on the open side, that is, near the corner of the inner frame 14. By providing this, it is possible to minimize the influence on the layout of the inner frame mounting component and the reduction of the installation space. Furthermore, by providing the opening / closing detection unit 120 integrally with the lower decoration 16, the configuration is simplified as compared with the case where such an opening / closing detection unit is configured separately and attached to the outer frame 12 or the lower decoration 16. can do.

  Further, when a push switch is used as the open / close detection switch 104 as in the present embodiment, for example, when the push button 108 is directly pressed by a highly rigid portion such as a part of the frame of the outer frame 12, the inner frame 14. Each time the button is closed, an impact is applied to the push button 108, and there is a concern that the durability may be lowered. In addition, the open side end portion having a large distance from the rotation support shaft tends to have a larger impact force when the inner frame 14 is closed than the base end side end portion having a small distance from the rotation support shaft. In the configuration in which the open / close detection switch 104 is arranged at the open end as in the embodiment, the durability of the open / close detection switch 104 tends to be disadvantageous compared to the configuration arranged at the base end.

  On the other hand, if the plate spring 124 is provided in the opening / closing detection unit 120 as described above, an impact that acts on the push button 108 when the inner frame 14 is closed is absorbed by the plate spring 124. It is possible to prevent a decrease in the durability of the 104, and in particular, as in the present embodiment, a longer life can be achieved even in a configuration in which the open / close detection switch 104 is disposed at the open end of the inner frame 14.

  As mentioned above, although this invention was demonstrated in detail by the specific embodiment mentioned above, this invention is not limited to it, Various other forms can be implemented within the scope of the present invention.

  For example, in the above-described embodiment, a push switch is used as the open / close detection switch 104 as detection means for detecting the open / close state of the inner frame 14 with respect to the outer frame 12, but a limit switch or the like may be used. Further, the impact absorbing means for absorbing the impact acting on the push button 108 of the open / close detection switch 104 when the inner frame 14 is closed is constituted by a metal leaf spring 124. In addition, it may be configured by an elastic member such as a spring or an elastomer.

  The present invention is not limited to the pachinko machines described above, and can also be applied to other gaming machines such as a pachislot machine having an opening / closing body that is opened and closed with respect to a base body and various amusement machines.
