Further, the slidable contact members 37a to 37d themselves are also formed in a plate spring shape, and are configured to slidably contact with each other by pressing the slidable contact members 37a to 37d themselves against the shaft mounting portion 50 by an urging force.

  Therefore, by attaching the pivoting portion 50 of the opening / closing panel member 17 to the pivoted portion 37 of the front frame 3, the pivoting portion upper portion 50a that is insulated when the opening / closing panel member 17 is detached from the pivoting portion 37 is removed. The shaft attachment portion lower portion 50c is electrically connected to the shaft attachment portion 37 and the sliding contact members 37a to 37d. As a result, the shaft attachment detection unit 55 can detect that the shaft attachment portion 50 is conducted to the shaft attachment portion 37.

  In the present embodiment, the sliding contact members are arranged at the upper part of the pivoted part 37, two at the side part, and one at the lower part as in the sliding contact members 37a to 37d. For example, two pieces may be provided only on the side portion, and other numbers of sliding contact members may be used.

  Further, the sliding members 37a to 37d are plate springs for pressing against the shaft mounting portion 50, but the present invention is not limited thereto. For example, between the shaft mounting portion hinge shaft 30 and the shaft mounting portion upper hole 51 and the shaft mounting portion. Between the lower hole 39 and the shaft-mounting portion lower shaft 52b, a washer such as a spring washer or a bearing made of a conductive material (for example, metal) is interposed, and a bearing or the like. By electrically connecting the upper surface portion, the lower surface portion of the pivoted portion 37 and the pivoted portion lower shaft 52b, the pivoted portion upper portion 50a and the pivoted portion lower portion 50c may be electrically connected.

  Next, an electrical configuration for firing control of the launching device 402 and detection of opening of the open / close panel member 17 will be described.

  FIG. 7 is a block diagram of the launch control device 400 and the open / close panel member 17 according to the first embodiment of this invention. FIG. 8 is an explanatory diagram of the open / close detection switch 175a according to the first embodiment of this invention.

  In the present embodiment, by connecting the connector 409 connected to the launch control device 400 and the connector 179 included in the open / close panel member 17, the launch control device 400 and the open / close panel member 17 are electrically connected. The

  The launch control device 400 is a control device that controls the launch of the game ball by the launch device 402 based on the operation of the launch operation unit 19 by the player, and includes a CPU 401, a ROM 402, a RAM 403, an interface 404, a bus 405, and a connector 409. The launch control device 400 functions as a launch restriction unit.

  The CPU 401 is an arithmetic processing unit that includes a calculation unit and controls the launching of the game ball by the launching device 402. The ROM 402 is a memory that stores invariant information for launch control such as a program for executing control processing and control data. The RAM 403 is a memory used as a work area during control.

  The interface 404 is an input / output port through which the launch control device 400 transmits and receives signals to and from other devices.

  The connector 409 can be connected to the connector 179 on the open / close panel member 17 side. By connecting the connector 409 and the connector 179, the firing control device 400, the shaft attachment detector 55, the opening detection switch 175a, the touch detection switch 191a, and the firing operation detection switch 19a arranged on the open / close panel member 17 are connected. The electromagnet 183 of the ball feeding mechanism 18 and the rotary solenoid 104 of the launching device 402 are connected.

  The bus 405 includes an address bus and a data bus that the CPU 401 uses for reading and writing data. The CPU 401, ROM 402, RAM 403, and interface 404 are connected by a bus 405.

  On the open / close panel member 17, a shaft attachment detector 55, an open / close detection switch 175 a, a touch detection switch 191 a, a firing operation detection switch 19 a, an electromagnet 183 provided in the ball feed mechanism 18, and a rotary solenoid 104 provided in the launch device 402 are disposed. The

  The shaft attachment detection unit 55 detects that the open / close panel member 17 is mounted on the front frame 3 as described with reference to FIG. 6.

  As shown in FIG. 8, the opening / closing detection unit 175 includes a wall portion 175b having a rectangular cross section, and is formed so as to surround the four sides of the recess 175c by the wall portion 175b. The opening detection unit 175 includes an opening detection switch 175a in an inner recess 175c surrounded by the wall 175b.

  The open / close detection switch 175a is a detection member that is provided inside the recess 175c of the open / close detection unit 175 and detects that the open / close panel member 17 is open. The open / close detection switch 175a includes a switch body 175a1 and a push button 175a2. The open / close detection switch 175a is closed when the push button 175a2 is not pressed and is opened when the push button 175a2 is pressed.

  The push button 175a2 is in contact with the protruding member 35 disposed on the front frame 3 when the open / close panel member 17 is closed. For this reason, when the open / close panel member 17 is opened, the push button 175a2 is not pressed by the protruding member 35, so the open / close detection switch 175a is closed. However, when the open / close panel member 17 is closed, the push button 175a2 is pressed by the protruding member 35. Thus, the open / close detection switch 175a is opened. Accordingly, the open / close detection switch 175a can detect that the protruding member 35 is in contact with the open / close detection switch 175a.

  Further, as shown in FIG. 8, the push button 175a2 of the open / close detection switch 175a is covered with a wall portion 175b. As a result, when a game shop clerk or the like is working with the open / close panel member 17 in an open state, a part of the body accidentally touches the open detection switch 175a, causing the launching device 402 to malfunction. Is prevented.

  The touch detection switch 191a detects that the player's hand is touching the firing operation unit 19 based on a change in capacitance.

  The firing operation detection switch 19a uses a variable resistor to detect that the firing operation unit 19 has been turned by the player.

  As described above, the electromagnet 183 drives the ball feeding member 182 included in the ball feeding mechanism 18 to send the game ball to the launching device 402. In addition, as described above, the rotary solenoid 104 drives the bullet member 102 included in the launching device 402 and bullets the game ball.

  The shaft attachment detection unit 55 and the open / close detection switch 175a are connected in series to constitute the circuit 17a. For this reason, when the open / close panel member 17 is pivotally attached to the front frame 3 and the axial attachment detection unit 55 becomes conductive, the open / close detection switch 175a is normally closed. The entire 17a is closed.

  When the pivoted open / close panel member 17 is closed, the open / close detection switch 175a is opened by being pressed by the projecting member 35, so that the circuit 17a is opened.

  Further, the circuit 17b configured by the touch detection switch 191a is closed via the human body when it is detected that the player touches the firing operation unit 19, and the player If it is not detected that the firing operation unit 19 is touched, it is opened.

  Next, the operation of the launch control device 400 of the present embodiment will be described.

  A detection signal for detecting a rotation operation and a rotation operation amount of the player's shooting operation unit 19 output from the shooting operation detection switch 19 a is input to the shooting control device 400 via the interface 404.

  Based on the detection signal from the firing operation detection switch 19a, the firing control device 400 controls the electromagnet 183 according to the turning operation and the rotary solenoid 104 according to the turning operation amount.

  However, even if the firing operation detection switch 19a detects a turning operation, if at least one of the circuit 17a is closed or the circuit 17b is open, the firing control device 400 is an electromagnet. 183 and the rotary solenoid 104 are not operated. As a result, the game ball is not fired from the launching device 402.

  As described above, in the first embodiment, when the open / close panel member 17 is detected to be opened from the front frame 3 by the open / close detection switch 175a that detects the open state of the open / close panel member 17, Since the control device 400 does not actuate the electromagnet 183 and the rotary solenoid 104 for launching the game ball by the launch device 402, the launch device 402 does not operate while the open / close panel member 17 is open, so that the game ball is inadvertently launched. It will not be done.

  That is, when the open / close panel member 17 is pivotally attached but in the open state, the launching device 402 does not operate, so that the game ball is accidentally fired when the front frame 3 is opened and maintenance work is performed. Trouble can be prevented.

  In addition, since an opening / closing detection switch 175a is provided in a recess 175c formed by the wall portion 175b at a position where the protruding member 35 of the front frame 3 is inserted, an attendant touches the opening / closing detection switch 175a during work. Can be prevented.

  The open / close panel member 17 includes locking portions 171 and 176 for engaging with the front frame 3, and the front frame 3 is engaged with the locking receiving portion 36 and the locking portion 176 that engage with the locking portion 171. Since the engaging portions 171 and 176 are arranged in the vicinity of the open / close detecting portion 175 provided on the open / close panel member 17, the open / close panel is operated by the action of the engaging portions 171 and 176. When the member 17 is closed, the relative position between the open / close detection switch 175a and the protruding member 35 is stabilized, and the contact between the open / close detection switch 175a and the protruding member 35 is reliably detected by the open / close detection switch 175a.

  Further, the open / close panel member 17 is configured as a unit including the firing operation unit 19, and a shaft mounting portion 50 for pivotally mounting on the front frame 3, and the shaft mounting portion 50 pivots on the front frame 3. A shaft attachment detection unit 55 for detecting that the shaft attachment detection unit 55 is not attached. When the shaft attachment detection unit 55 detects that the shaft attachment unit 50 is not attached to the front frame 3, the opening / closing detection unit opens and closes the shaft attachment detection unit 55. Even when it is detected that the panel member 17 is released from the front frame 3, it is possible to launch a game ball by the launching device 402, so that when the open / close panel member 17 is not attached to the front frame 3, it is unitized. The inspection for operating the launching device 402 with the single open / close panel member 17 becomes possible.

  That is, in the design stage where the open / close panel member 17 is developed, or in the production process or inspection process of the open / close panel member 17 in the factory, the operation of the launch operation unit 19 and the launch device 402 provided in the open / close panel member 17 is inspected. In some cases, the connector 179 of the open / close panel member 17 is inserted into the connector 409 of the firing control device for inspection (a control device equivalent to the fire control device 400). 17 is not attached to the front frame 3 by the shaft attaching portion 50, so that the firing device 402 can be operated by the operation of the firing operation portion 19 regardless of the detection state of the open / close detection switch 175 a.

  Therefore, since the opening / closing panel member 17 provided with the launching device 402 and the firing operation unit 19 as a unit can be inspected by a single unit of the opening / closing panel member 17 without being attached to the front frame 3, Time work can be made more efficient.

  Further, the front frame 3 includes a U-shaped pivoted portion 37 made of a conductive material (for example, metal) that engages with the pivoted portion 50 of the open / close panel member 17. The shaft attachment portion 50 of the open / close panel member 17 is formed with a shaft attachment portion upper portion 50a and a shaft attachment portion lower portion 50c made of a conductive material (for example, metal) that are insulated from each other at both ends. Then, when the pivoting portion 50 is inserted into the pivoted portion 37, the pivotal portion upper portion 50 a and the pivotal portion lower portion 50 c formed at both ends of the pivotal portion 50 a are connected via the pivoted portion 37. It becomes a conductive state. As a result, since the state where the shaft mounting portion 50 is mounted on the front frame 3 is detected, it has a function of detecting the shaft mounting state. In addition, when the pivoted portion 37 is made of metal, it can be provided with conductivity and durability can be increased, which is more economical in design.

(Second Embodiment)
Next, a second embodiment will be described.

  In the second embodiment, the configuration of the open / close detection switch 175a has a simple structure with contacts 175a3 and 175a4 including two plates of conductive material (for example, metal), and the protruding member 35 is made of a conductive material (for example, It is made of metal) and is different in that it is configured to be fitted when the open / close panel member 17 is closed. In addition, the same code | symbol is attached | subjected to the structure which performs the same effect | action as 1st Embodiment, and the description is abbreviate | omitted.

  The electrical configuration of the firing restriction of the launching device 402 and the detection of the opening of the open / close panel member 17 according to the second embodiment will be described.

  FIG. 9 is an explanatory diagram of the open / close detection switch 175a according to the second embodiment of this invention. FIG. 10 is a block diagram of firing control and open detection of the launch control device 400 and the open / close panel member 17 according to the second embodiment of the present invention.

  As shown in FIG. 9, the open / close detection switch 175a of the present embodiment is provided inside a recess 175c included in the open / close detection unit 175, and detects that the open / close panel member 17 is open. The open / close detection switch 175a includes contacts 175a3 and 175a4 made of a conductive material (for example, metal).

  In the open / close detection switch 175a, the contacts 175a3 and 175a4 are insulated when the detection object is not touching, and a conductive material (for example, metal) disposed on the front frame 3 when the open / close panel member 17 is closed. The protruding member 35 is configured to be fitted and contactable. In other words, the continuity detection unit is configured by the contacts 175a3 and 175a4, and the contact action unit of the protruding member 35 is fitted and brought into contact with the continuity detection unit.

  For this reason, when the open / close panel member 17 is closed, the open / close detection switch 175a can conduct between the contacts 175a3 and 175a4 by inserting the protruding member 35 having conductivity between the contacts 175a3 and 175a4. The open / close detection switch 175a is closed. In this way, the firing control device 400 can detect the open state of the open / close panel member 17 based on the conductive state of the open / close detection switch 175a.

  Further, as shown in FIG. 9, the contacts 175a3 and 175a4 of the open / close detection switch 175a are covered with a wall portion 175b provided in the open / close detection unit 175, and are further opened / closed depending on whether or not the insulated contacts 175a3 and 175a4 are conductive. In this configuration, the open state of the panel member 17 is detected.

  As a result, when the human body touches the contacts 175a3 and 175a4, the resistance value is larger than when the protruding member 35 made of a conductive material comes into contact. Since it is easy to discriminate from the case of the game, when a store clerk or the like of the game hall is working with the open / close panel member 17 in an open state, a part of the body accidentally touches the open detection switch 175a and the launching device Troubles in which the 402 malfunctions are prevented.

  In the present embodiment, as shown in FIG. 10, the shaft attachment detection unit 55 and the open / close detection switch 175a constitute a circuit 17c and a circuit 17d, respectively.

  The circuit 17c is in a closed state when the axis attachment detection unit 55 detects the axis attachment of the opening / closing panel member 17 to the front frame 3, and the axis attachment detection unit 55 detects the axis attachment of the opening / closing panel member 17 to the front frame 3. If not detected, it will be open.

  When the open / close panel member 17 is closed, the contacts 175a3 and 175b4 of the open / close detection switch 175a and the projecting member 35 are brought into contact with each other, and the circuit 17d is closed. On the other hand, when the open / close panel member 17 is opened, the open / close detection switches 175a3 and 175a4 are insulated, and the circuit 17d is opened.

  Next, the operation of the launch control device 400 of the present embodiment will be described.

  A detection signal for detecting a rotation operation and a rotation operation amount of the player's shooting operation unit 19 output from the shooting operation detection switch 19 a is input to the shooting control device 400 via the interface 404. Based on the detection signal from the firing operation detection switch 19a, the firing control device 400 controls the electromagnet 183 according to the turning operation and the rotary solenoid 104 according to the turning operation amount.

  However, as in the first embodiment, even if the firing operation detection switch 19a detects a turning operation, if the circuit 17b is open, the firing control device 400 includes the electromagnet 183 and the rotary solenoid 104. Do not operate. As a result, the game ball is not fired from the launching device 402.

  Furthermore, in addition to this, the firing control device 400 is configured such that both the circuit 17c and the circuit 17d are open, or the circuit 17c and the circuit 17d are both opened, even if the firing operation detection switch 19a detects the turning operation. Even when it is closed or filled, the electromagnet 183 and the rotary solenoid 104 are not operated, and the game ball is not fired.

  As described above, in the second embodiment, since the opening / closing panel member 17 is detected based on whether or not the insulated contacts 175a3 and 175a4 are conductive, even if the human body touches the contacts 175a3 and 175a4. Since the resistance value is larger than that of the projecting member 35 made of a conductive material, it is easy to distinguish between the case where the projecting member 35 is in contact with the contacts 175a3 and 175a4 and the case where the human body is touched. As a result, for example, when an attendant is performing maintenance work with the open / close panel member 17 in an open state, a part of the body may accidentally touch the open detection switch 175a, causing a problem that the launching device 402 malfunctions. Is further reduced.

  Further, since the open / close detection switch 175a is configured by the contacts 175a3 and 175a4 which are two conductive materials (for example, metal plates), the effects of the present invention can be realized with a simple configuration.

  The embodiment disclosed this time is illustrative in all points and is not restrictive. The scope of the present invention is shown not by the above description of the invention but by the scope of claims, and is intended to include all modifications within the scope and meaning equivalent to the scope of claims.
