Description

[Detailed description of the invention] [Field of industrial application] The present invention is a pachinko machine in which all the parts of the ball pulling device are assembled into a case body, and the case body is attached to the inside of the mechanism plate. This relates to the installation structure of a ball removing device in a machine.

[Prior Art] In conventional pachinko machines, the ball extraction device parts are arranged on the surface of a mechanism plate to which a series of back parts such as the prize ball ejecting mechanism are attached, so it is necessary to perform some kind of repair on the back parts. If this is not the case, your hand may touch the ball removing device parts and accidentally remove the ball.
Alternatively, a situation may arise in which repairs cannot be made without removing these device parts. Furthermore, the positional relationship of the back parts differs depending on the manufacturer, and therefore, the back parts may get in the way and make it difficult to install the ball removing device.

The present applicant has proposed that by arranging the ball removing device parts in the space forming the safe ball collecting part inside the mechanism plate, repair and inspection of other back parts can be easily carried out, and moreover, it can be done without being obstructed by these back parts. Japanese Utility Model Publication No. 57-42471 has already proposed a ball-removing structure for a pachinko machine that can be easily attached to any type of machine.

[Problems to be Solved by the Invention] The ball extractor structure of this pachinko machine is such that each ball extractor component is directly assembled to a mechanism plate, etc., which makes the work extremely troublesome and time-consuming. Furthermore, it is not easy to replace parts when a failure occurs.

[Means for solving the problem] An engaging part is provided on the sliding body that receives the tip of the swinging bottom piece provided in the ball extraction opening of the lead-out gutter, and the engaging part is located inside the mechanism plate. Assembling the ball punching device parts such as a rotatable actuating plate having a protrusion and an interlocking member for rotating the actuating plate into the case body,
Attach this case body to the inside of the mechanism plate, and
The protruding portion of the actuating plate is engaged with the engaging portion of the sliding body.

[Operation] When the actuating plate is rotated, the sliding body is pushed by the protrusion and moves rearward, and the tip of the swinging bottom piece is released from being supported by the sliding body and becomes free. The weight of the ball causes the swinging bottom piece to rotate downward, opening the ball removal opening and allowing the ball to be removed.

[Example] In the figure, 1 is a pachinko machine main body, 2 is a game board, and 3 is a mechanism plate that is attached to the back side of the game board 2 so that it can be opened and closed, and has a ball tank on the outside upper part. 4 is installed, and a lead-out gutter 5 is installed in an inclined manner at the bottom of the ball tank 4 to guide the balls in the ball tank 4 to a prize ball case 6. As shown in FIG. 5, the inner side of the mechanism plate 3 forms a safe ball gathering portion 7 as a concave surface separated from the back surface of the game board 2 at a constant interval. As shown in FIG. 6, the outlet gutter 5 has a ball removal opening 8 at the bottom of the flow path, and a pair of swinging bottom pieces 9, 9 bent into a substantially shape are provided in the ball removal opening 8.
is rotatably supported by a shaft 10. The swinging bottom pieces 9, 9 have a restoring force that always returns to the position shown by the solid line in FIG. is held in the desired position.

The sliding body 12 is slidably held with one side edge facing a groove 13 formed in the outer wall of the outlet gutter 5 and the other side edge facing a long groove hole 14 bored in the mechanism plate 3. be done. Further, the sliding body 12 has a side piece 15 located in a space forming the safe ball gathering part 7 inside the mechanism plate 3.
A U-shaped engaging portion 17 is formed by protruding protrusions 16, 16 on the
is formed.

Reference numeral 18 denotes a box-shaped case body with an open side surface corresponding to the inner surface of the mechanism plate 3, and a rotatable operating plate 19 and a ball removal device such as an interlocking member for rotating the operating plate 19 are mounted on the box-shaped case body. Parts are assembled all at once. The actuating plate 19 is attached to the case body 1 as shown in FIG.
The right upper end is pivotally supported by a shaft 20 protruding from the inner lower part of the sliding member 8, and a protrusion 21 that can engage with the engaging portion 17 of the sliding body 12 is provided on the shaft 20. Reference numeral 22 denotes a solenoid as an interlocking member, which is fixed at a position above the actuating plate 19 with screws or the like. A connecting body 25 having a through groove 24 is attached to the lower end of the plunger 23 of the solenoid 22, and another protrusion 26 provided on the actuating plate 19 is inserted into the through groove 24 and connected, and is wound around the plunger 23. This applies the downward force of the spring 27 to the operating plate 19. Reference numeral 28 is an interlocking lever whose substantially central portion is supported by the case body 18 through a shaft 29, and one end of which faces the lower surface of a circular flange 30 provided at the upper end of the plunger 23 of the solenoid 22. Reference numeral 31 denotes an operating lever, the lower end of which is pivotally supported on the case body 18 by a horizontal shaft 32 so as to be able to swing back and forth.
Connect the arm 33 and the other end of the interlocking lever 28 with the link 3
4 to connect them in an interlocking manner.

Thus, the case body 18 in which the ball removing device parts are assembled as described above has its open side surface applied to the inner surface of the space forming the safe ball gathering portion 7 of the mechanism plate 3, and the protrusion of the operating plate 19 21 is engaged with the engaging portion 17 of the sliding body 12 and attached using screws or the like.
As a result, the sliding body 12 is always placed in a position where it receives the tips of the swinging bottom pieces 9, 9, as shown by the solid line in FIG. Further, the upper end of the operating lever 31 is positioned to protrude outward from the mechanism plate 3.

3 In this embodiment, when the solenoid 22 is energized, the plunger 23 is attracted upward against the spring 27, and the actuating plate 19 rotates as shown by the chain line in FIG. In order to move the swinging bottom pieces 9 in the direction, the support of the tips of the swinging bottom pieces 9, 9 by the sliding body 12 is released and the swinging bottom pieces 9, 9 are in a free state. As a result, due to the weight of the ball, the swinging bottom pieces 9, 9 rotate downward as shown by the chain line in FIG. You can remove the ball by doing so. When the ball removal is completed, the swinging bottom pieces 9, 9 move back to the solid line position in FIG.
By re-energizing and moving the sliding body 12, the swinging bottom pieces 9, 9 can be held in a position that closes the opening 8 for removing balls. Furthermore, when the operating lever 31 is pressed in the state shown by the solid line in FIG. 7, the interlocking lever 28 swings upward via the connecting rod 34 as shown by the chain line in the same figure, thereby pulling the plunger 23 of the solenoid 22 upward. , you can extract the ball in the same way as above.

FIG. 8 shows another embodiment different from the embodiment described above, in which the interlocking lever 28 and the actuating plate 19 are made mechanically interlockable by using an interlocking body 35 instead of the solenoid 22. be. In this embodiment, when the operation lever 31 is pushed, the interlocking body 35 is pulled upward via the interlocking rod 34 and the interlocking lever 28, and the ball can be removed in the same manner as described above. In FIG. 8, the same parts as in FIGS. 1 to 7 are denoted by the same reference numerals.

[Effects of the invention] The back structure of the pachinko machine can be improved by attaching the ball extracting device parts to the case body in the space that forms the safe ball gathering area inside the mechanism plate. In addition to being simple, the arrangement of the ball punching device is extremely easy since troublesome mutual positioning of parts is unnecessary, and replacement of parts in the event of failure is also extremely easy.
