Then, the winning ball cover 11 of the game board 3 faces the space area S surrounded by the mechanism board 4 in a U-shape. In the lower half 4 </ b> B of the mechanism plate 4, a winning ball collecting basket 18 is opened upward to receive all winning balls discharged from the winning ball cover 11. The received winning balls are sent to a winning ball processing device (not shown) in the lower half 4B and discharged out of the machine.
[0010]
The mechanism plate 4 is pivotally supported by a hinge tool interposed between the mechanism plate 4 and the crosspiece member 6. As described above, the mechanism plate 4 of this embodiment is divided into the upper half 4A and the lower half 4B, and a hinge structure as shown in FIG. That is, the hinges A, B, and C are fixed metal fittings 19A, 19B, and 19C that are screwed to the crosspiece member 6 of the front frame 2, and rotary metal fittings 20A, 20B-1, that are screwed to the mechanism plate 4 side. Each of 20B-2 and 20C is rotatably coupled. Each of the fixing brackets 19A, 19B, and 19C includes a mounting substrate 21 that is screwed to the side surface of the crosspiece member 6 and a horizontal arm plate 22 that protrudes from the mounting substrate 21, and the fixing bracket 19A is attached to the horizontal arm plate 22. Are formed with a bearing hole 23, a shaft cylinder 24 protruding downward on the fixing bracket 19 </ b> B, and an upward short shaft 25 on the fixing bracket 19 </ b> C.
[0011]
The rotary fittings 20A and 20B-1 are attached to the upper half 4A, and the rotary fittings 20B-2 and 20C are attached to the lower half 4B. Each of the rotating brackets 20A, 20B-1, 20B-2, and 20C includes an attachment board 26 for screwing to the mechanism plate 4, an arm rod 27 projecting vertically from the attachment board 26, and the arm rod 27 And a bearing plate 28 formed at the tip. Then, rotating shafts 29 and 29 project downward from the bearing plate 28 of the rotating metal fittings 20A and 20B-1 of the upper half 4A, and the rotating shafts 29 and 29 are bearings of the fixing metal fitting 19A. The hole 23 is loosely fitted into the cylindrical hole of the shaft cylinder 24 of the fixing bracket 19B. On the other hand, a rotation shaft hole 30 is formed in the bearing plate 28 of the rotation fittings 20B-2 and 20C of the lower half 4B, and the shaft cylinder 24 of the fixing fitting 19B is fixed to the rotation shaft hole 30. The short shaft 25 of the metal fitting 19C is loosely fitted. The shaft cylinder 24 of the fixing bracket 19B is formed slightly longer than the short shaft 25 of the fixing bracket 19C. Therefore, first, the rotating metal fitting 20B-2 is fitted to the shaft cylinder 24, and the lower half 4B is lifted until the bearing plate 28 is attached to the base portion of the shaft cylinder 24. In this state, the rotating metal fitting 20B-2 is placed on the axis of the short shaft 25. If the lower half body 4B is lowered by aligning the rotation shaft hole 30 of 20C, the rotation fittings 20B-2 and 20C cannot be removed while being engaged with the shaft cylinder 24 and the short shaft 25, respectively.
[0012]
By adopting the above hinge structure, the mechanism plate 4 can rotate the upper half body 4A and the lower half body 4B independently of each other. Further, by adopting a configuration in which one fixing bracket 19B is shared by the rotating bracket 20B-1 of the upper half 4A and the rotating bracket 20B-2 of the lower half 4B, the efficiency of the fixing bracket mounting work can be improved. Cost burden can be reduced. In addition, the code | symbol 31 in a figure is a fastener for locking the mechanism board 4 to a closed position.
[0013]
Thus, the interference avoidance means employed in the first embodiment between the mechanism plate 4 and the outer frame 1 has the structure of hinges A, B, and C. That is, as shown in FIG. 7, the conventional hinge device 104 rotates the mechanism plate 105 with the front frame 102 closed because the rotation center of the mechanism plate 105 is set inside the rear edge of the outer frame 101. Attempting to do so causes the outer frame 101 and the mechanism plate 105 to immediately interfere with each other. Therefore, as shown in FIGS. 1 and 4, the horizontal arm plates 22 of the fixing brackets 19A, 19B, and 19C and the arm rods 27 of the rotating brackets 20A, 20B-1, 20B-2, and 20C are respectively extended backward. Thus, the rotation center of the mechanism plate 4 is moved to the outside of the outer frame 1. As a result, as shown in the two-dot chain line in FIG. 1, the mechanism plate 4 can be rotated directly from the back of the outer frame 1 to the workable opening angle even when the front frame 2 is closed. Of course, the mechanism plate 4 (upper half body 4A, lower half body 4B) can be removed from the crosspiece member 6 by rotating to this position.
[0014]
[Example 2]
FIG. 6 is a cross-sectional plan view of the main part of the pachinko machine showing the second embodiment. The interference avoiding means of the second embodiment is in the structure of the outer frame 1. That is, the concave portion 32 for avoiding interference is formed in the outer frame 1 without changing the rotation center of the mechanism plate 4 from the conventional position. By doing so, the rotation side end portion of the mechanism plate 4 and the outer frame 1 do not interfere with each other as shown by a two-dot chain line in FIG. 6, so that the mechanism plate 4 can be rotated even when the front frame 2 is closed. In addition, in order to clarify the recessed part 32, one form of the recessed part 32 was indicated on the outer frame 1 in FIG.
[0015]
Although the present invention has been described with reference to the first and second embodiments, the present invention is of course not limited to the above-described embodiments. For example, the following (1) to (3) can be considered as specific examples of other variations.
(1) Although the mechanism plate 4 of the first embodiment has been divided into an upper half body 4A and a lower half body 4B, the mechanism plate is divided into three parts or a general one-piece structure. It can also be applied to mechanism plates.
(2) In addition to the structure of the hinge tool shown in the first embodiment, for example, a short shaft and a long shaft project from the upper and lower surfaces of the bearing plate 28 of the fixing bracket 19B, and the rotating bracket 20A of the upper half 4A The same rotation shaft hole as the rotation fittings 20B-2 and 20C of the lower half 4B may be formed in 20B-1. Further, two fixing brackets 19B are separated for the upper half body 4A and the lower half body 4B, bearing holes are formed in the bearing plates 28 of all the fixing brackets, and the rotating bracket for the lower half body 4B is further formed. The same rotation shaft as that of the rotation fittings 20A and 20B-1 of the upper half 4A may be provided on 20B-2 and 20C.
(3) Since the present invention enables the mechanism plate 4 to be rotated with the front frame 2 closed, the front frame inevitably does not overlap the back surface of the game plate 3. 2 can be closed. Therefore, there is a possibility that the front plate 2 may be closed without carelessly forgetting to close the mechanism plate 4, or the mechanism plate 4 may naturally rotate during play due to a lock failure. Therefore, it is conceivable to add a sensor for detecting that the mechanism plate 4 is in the closed position to the present invention. That is, a sensor such as a micro switch or a reed switch is installed at the points indicated by reference numerals X and Y in FIG. 3 and an electrical signal is sent to the control device that the mechanism plate 4 is in the closed position. If it is not in the closed position, the game is interrupted as a malfunction of the operating environment, or it is set so as to notify the manager to that effect. For example, when a micro switch is used as the sensor, the switch body is fixed to the back surface of the mechanism plate 4 so that the actuator piece is brought into contact with the back surface of the game board 3 or the back surface of the crosspiece member 6. When a reed switch is used as a sensor, the reed switch may be fixed to the back surface of the mechanism plate 4 and a small permanent magnet may be attached to the back surface of the game board 3 or the back surface of the crosspiece member 6. By adopting such a configuration, it is possible to prevent troubles such as forgetting to close the mechanism plate 4 due to carelessness as described above and natural rotation of the mechanism plate 4 due to a lock failure. Needless to say, the mechanism plate 4 in this case may be a single-sheet structure or a multi-segment structure. However, in the case of a multi-division structure, it is desirable to detect the closed position for each of the divisions.
