More specifically, the structure is such that the drive is not overloaded when a movable device provided on the medal drop table is clogged with medals, and the device does not wear even after long-term use. It was designed for the purpose of simplifying the process.

(Means for Solving the Problems) A medal game device of the present invention is a medal dropping game device for dropping coin-shaped medals onto a medal dropping plate, and is fixed to a pivot provided at right angles to the medal dropping plate. A swinging part for receiving and swinging out a medal, a boss fixed to the pivot protruding to the back side of the medal drop board, a swing bar having one end rotatably pivotally attached to the pivot, and provided on the boss A pair of guides pivotally attached to a support shaft to clamp the swing bar from both sides, a biasing means for biasing the swing bar by the pair of guides, and the swing bar. Drive means for swinging to the left and right around the pivot axis.

(Operation) To explain the operation of the present invention, the swinging rod pivotally attached to the pivot is swung by the drive means provided on the back side of the medal drop board. Then, the swing rod pushes either one of the left and right sides of the pair of guides holding the swing rod in the swinging direction. The guide is rotatably pivotally attached to a support shaft provided on a boss fixed to the pivot shaft, and is biased by a biasing means so as to clamp the swing rod. A swinging part fixed to the pivot is provided on the medal drop board surface, and the swinging part and the boss are fixed by the pivot, and when no load is applied to the swinging part,
The swing rod swings the guide in accordance with the swing by the driving means, and since the guide holds the swing rod and urges it, the support shaft of the guide is swung in the opposite direction as it is to rotate the boss. The oscillating portion is also rotated to oscillate.

Next, if some load is applied to the swing part and it does not move,
When the swing rod swings to the left and right, the boss fixed to the swinging portion via the pivot does not move, and the support shafts of the pair of guides that sandwich and swing the swing rod also remain fixed. Here, since the swing bar moves in the swing direction by the swing of the drive means, the guide on the swing direction side overcomes the biasing force of the biasing means and is pushed out around the supporting shaft to swing the swing bar. Then, the drive means is rocked.

Is arranged so that it can swing freely. The oscillating portion 3 has walls on both sides and has a wide upper opening and a narrow lower opening so that coin-shaped medals can pass through.

A switch operation bar 5 is projected in a long hole 4 in the lower center of the medal drop board 1 so as to be retractable from the medal drop board.

Above the long hole 4, a pair of wings 6 is arranged so as to be openable and closable with a distance slightly wider than the diameter width of the medal. The medal drop board 1 is provided with a large number of pins 7 at intervals larger than the diameter width of the medal in order to flip the medal falling from above and change the falling direction of the medal.

On the medal drop board, a transparent plate (not shown) is provided over the entire surface of the medal drop board parallel to the medal drop board with a distance slightly larger than the thickness width of the medal from the surface of the medal drop board.

The medals dropped by the player on the medal dropping game device are
It rolls down on the deceleration path 2 from above the medal drop board 1 and enters the swing section 3 through the upper opening of the swing section 3. The swinging unit 3 swings to the left and right by a drive device, and the medals that have entered the swinging unit 3 fall while being changed in the falling direction according to the swinging of the swinging unit 3 and ejected from below the swinging unit 3. Is done. This causes a change in the drop of the medal, and disperses the movement of the medal after that.

Here, the drive device of the swinging portion 3 will be described with reference to FIGS. 2 and 3. A drive unit for a swinging unit is provided on the back side of the medal drop board 1, and an arm 12 fixed to a rotation shaft of a motor 11
Has a link 13 rotatably arranged at its tip. At the other end of the link 13, a long joint 14 and a swing rod 15 which are rotatably provided are rotatably provided. The joint 14 is rotatably connected to the swing bar 15 of the swinging part 3 which is remote from the motor 11.

The end of the swing bar 15 is rotatably attached to a pivot 16 provided so as to penetrate the medal drop table 1 at a right angle. A disc-shaped boss 17 is fixed to the pivot 16 between the swing bar 15 and the medal drop board on the back side of the medal drop board 1. The pivot 16 is fixed to the swinging portion 3 on the medal drop board surface side.

A pair of guides 18 having a substantially U shape are provided on the boss 17 and the pivot 16 is provided.
Separately from the above, it is rotatably attached to the support shaft 19. The guides are paired and hold the swing bar 15, and springs 20 are stretched near the tips of both guides to urge the swing bar in the sandwiching direction.

Stoppers that come into contact with the swing rod are located inside the tips of both guides.
21 are attached respectively and are in contact with the side surface of the swing rod 15.

The motor 11 is attached to the back surface of the medal drop board 1 with a bracket 22 so that the rotating shaft is perpendicular to the medal drop board 1.

In the embodiment having the above-described configuration, description will be made assuming that a large load is not applied to the rocking portion 3.

When the motor 11 rotates, the joint 14 reciprocates left and right through the arm 12 and the link 13. As a result, the swing rods 15 connected to each other swing around the respective pivots 16.

Then, the swing rod 15 swings left and right around the pivot 16, and when the swing rod 15 swings to the right, for example, the swing rod 15 contacts the stopper 21 of the right guide pivotally supported by the boss 17 and pushes it to the right. . Since the guide 18 urges the swing rod 15 to be sandwiched, the stopper 21 is pushed by the swing rod 15 and moves to the right, and the guide 18 leans to the right with the swing rod sandwiched. At this time, since the guide 18 tilts to the right around the pivot 16, the guide shaft
19 moves to the left position and rotates the boss 17 clockwise. As a result, the pivot 16 fixed to the boss 17 rotates to the right,
The swinging part 3 fixed to 16 swings to the right and swings. As a result, the medals that have fallen along the deceleration path 2 enter through the upper opening of the swinging unit 3, change the falling direction toward the swinging direction of the lower opening, and drop the medal drop board 1. The same applies when the swing bar 15 swings to the left.

Next, description will be made assuming that the swing unit 3 does not move due to a medal jam. As a case where the clogging of medals occurs, there is a case where the medals inserted by the player are bent or the medals are different in size and thickness and are caught in the swinging unit 3. In this case, a large load is applied to the operation of the swing unit 3.

In FIG. 3, when the motor 11 rotates, the joint 14 reciprocates left and right through the arm 12 and the link 13, and the joint 14 is on the right side, the connected swing bar 15 It will swing to the right around each pivot 16.

Here, when the left swinging part 3 is swung to the left and does not move due to clogging of medals or the like, the swing bar 15 contacts the stopper 21 of the right guide and pushes it to the right. Boss 17 in this state
Is fixed to the pivot 16 and does not move with the swing part,
The support shaft 19 of the guide provided on the boss 17 is located on the lower right side.
The guide 18 on the left side, which is pivotally supported on the
It remains in a state of abutting against and tilting to the left.

However, since the swing rod 15 is tilted to the right, the stopper of the right guide that abuts the swing rod 15 is pushed to the right. Then, the guide 18 urges the swing bar 15 to be clamped,
The right guide 18 pushed by the swing bar 15 moves to the right against the bias of the spring 20. Then both guides 18 and 18 are spindles 19.
It moves against the spring 20 stretched between the guides to the left and right around the center.

As a result, even if an accident such as a clogging of medals occurs in the swinging unit 3 and the player cannot move, the drive unit does not stop moving, and the motor 11 is not heavily burdened.
The same applies when the swing bar 15 swings to the left.

In the above description, the spring 20 is stretched near the tips of both guides 18, 18, but it is sufficient that the spring is biased in the direction of sandwiching the swing rod 15, and the spring 20 is wound around the pivot 16 so that both guides 18, 18 are wound. It may be a winding spring that urges.

In FIG. 2, on the back side of the medal drop board 1 above the wing 6 is a solenoid 31, and between the movable plate 32 having a substantially T shape and the medal drop board 1 located at the opposite side of the solenoid 31. A spring 33 is arranged to urge the movable plate 32 downward. The movable plate 32 is connected to a boss 34 fixed to the rotating shaft of the wing 6, and the movable plate 32 moves up and down to open and close the wing 6. When the movable plate 32 is on the lower side, the wing 6 is closed, and both wings of the wing 6 are parallel to each other with a distance slightly larger than the diameter width of the medal. When the solenoid 31 is energized, the movable plate 32 is pulled upward against the spring 33, and the movable plate 32 opens the wing 6 by rotating the boss in the direction in which both wings of the wing open.

(Effect of the Invention) In the present invention as described above, since the swing bar swings the swinging part to the left and right through the pair of guides and the spring, the swinging part is jammed and does not move. However, a large load is not applied to the drive system, and a load such as burning of the motor is not applied. In addition, since the pair of guides and springs hold the swing rod that moves the swinging part, there are no wear parts and sufficient movement can be expected for long-term use, and the pivot can be attached during assembly of the drive system. It has excellent effects such as being easy.
