[Problems to be solved by the device]

 However, the clutch mechanism operates according to the outer diameter and the thickness of the coin, but if the outer diameter and the thickness are the same, there is a problem that the counterfeit coin will also operate. Yes, and the coin had to be firmly fixed to the clutch mechanism. Furthermore, after the handle has been rotated once or rotated by a predetermined angle, the operation of the handle is stopped, and the capsule ejection disc also stops operating after the prescribed number (usually one) of capsules have been dispensed. There was nothing more than that, the steering wheel was spinning idle.

An object of the present invention is to provide a clutch structure in which the authenticity of coins can be easily discriminated, the coins need only be inserted, and the handle can be continuously rotated even after the prize is paid out.

[0005]

In order to achieve the above object, a clutch structure used in a prize dispenser of the present invention includes a handle, a first gear provided on the handle shaft, and a first gear. A second gear, which is connected to the gear by a crank member and always meshes with each other, and a third gear, which is engageable with and disengageable from the second gear as the crank member swings about the handle rotation shaft. Gear, a prize discharging means interlocking with the third gear, and a fixed and movable clutch plate on the handwheel rotating shaft that are in surface contact with each other. As the handle rotates, the movable clutch A structure in which the lever provided on the plate rotates and abuts on the coin inserted on the crank member, whereby the crank member swings and the second gear meshes with the third gear And At the same time, regardless of whether the handle is rotated or not, the coin is removed from the placing portion, so that the crank member swings toward the lever side by the spring, and the second gear moves to the third position. It is characterized in that the structure is separated from the gear.

According to the above structure, when the coin is inserted and the handle is rotated, the lever is rotated to push down the coin, so that the crank member swings and the second gear meshes with the third gear. , The rotation of the lever can be stopped, but the handle rotates as it is, the rotational force is transmitted in the order of the first gear, the second gear, and the third gear, and the prize is discharged by being linked to the prize discharging means. Be paid out. After paying out the prize, by removing the coin, the crank member is pulled up to the lever side by the spring and the second gear is disengaged from the third gear, so the rotational force of the handle is not transmitted to the prize discharging means. . Therefore, you can continue to rotate the handle even after paying out the prize.

[0007]

[Embodiment of device]

 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a structural view showing an example of an embodiment of the present invention, FIG. 2 is a view taken in the direction of arrow A in FIG. 1, and FIG. 3 is a perspective view for explaining the outline of the present embodiment. In these figures, the same reference numerals are given to the same structural parts as those in the example of FIG.

First, the outline of the present embodiment will be described with reference to FIG. When the handle 10 is turned, the directly connected gear 11 rotates, the gear 11 and the gear 12 always mesh with each other, and the gear 12 also rotates. When a coin (coin or medal) is inserted, the gear 12 swings in the direction of the arrow a in the figure around the shaft center of the gear 11 as the handle 10 rotates clockwise. It is supposed to mesh with. Therefore, the rotation of the handle 10 is transmitted to the gear 13, and the ejection disc 4 is rotated from the shaft 13a through the gear box 8 to dispense the prize capsule 5. When no coin is inserted, the gear 12 is disengaged from the gear 13 by the force in the b direction.

Next, one embodiment of the clutch structure of the present invention will be described in detail with reference to FIGS. 1 and 2. In these figures, the handle 10, the gear 11 and the shaft 20 are connected by a set screw or the like. One hole 22 of the crank 21 is loosely inserted into the boss portion of the gear 11, so that the crank 21 can swing slightly by performing a pendulum motion. The gear 12 is loosely inserted into the other hole 23 of the crank 21. Therefore, the gear 12 is engaged with the gear 13 by the swing of the crank 21 while keeping the meshed state with the gear 11. It is designed to leave.

A compression disk 24 is fixed to the shaft 20 of the handle 10 and a compression spring 25 is attached around the shaft 20. The compression spring 25 compresses to generate a frictional force, and After rotating the lever 26, it also generates a restoring force. A lever 26 is provided between the compression disc 24 and the compression spring 25. Friction materials 27 are adhered to the contact surfaces of the lever 26 and the compression disk 24, respectively. When the handle 10 is rotated, the lever 26 rotates in the same direction as the handle 10 due to the friction with the compression disk 24. However, when a certain resistance is generated, the lever 26 is stopped and only the handle 10 can be rotated.

On the other hand, a "U" -shaped sheet metal member 28 is combined with the end of the crank 21 on the gear 12 side, and a "U" such that the coin 1 is placed on the sheet metal member 28. A guide 29 which forms a V-shaped groove and serves as a side plate of the groove is provided. The guide 29 is provided with a hinge 30 provided at an end extending in the direction opposite to the mounting portion of the coin 1. It is fixed to the chassis 31 by.

A spring 32 is provided between the lever 21 and the crank 21 to which the “U” shaped sheet metal member 28 is attached. Further, stoppers 33 and 34 are provided above and below the lever 26, respectively, to restrict the turning range of the lever 26. The screw 35 is a screw for determining the degree of the crank 21.

The operation of the clutch structure shown in FIGS. 1 and 2 will now be described. As shown in FIG. 1, two coins 1 are inserted, sandwiched in the U-shaped groove by the guide 29, and placed on the "U" shaped sheet metal member 28. Now, when the handle 10 is turned in the direction of arrow c in the figure (clockwise in this case), a force is generated in the lever 26 in the direction of arrow a, and the tip portion pushes down the coin 1. Therefore, the crank 21 generates a force in the arrow d direction, and the gear 12 meshes with the gear 13.

Further, when the handle 10 is further rotated, the rotation operation of the lever 26 is stopped, but the rotational force is transmitted in the order of the gear 11, the gear 12, the gear 13, and the shaft 13a, and the ejection disc 4 shown in FIG. Around, the capsule 5 is dispensed.

The rotation of the ejection disc 4 has to be unidirectional in function, but in the present invention, it has been achieved mechanically well, and a part such as a one-way clutch needs to be provided on the handle shaft. There is no.

Even if a coin is inserted, when the handle is turned in the opposite direction (counterclockwise), the gear 12 and the gear 13 are separated from each other, and the capsule 5 is not paid out. Simultaneously with the payout of the capsule 5, the U-shaped guide 29 opens in the direction of arrow e, and the coin 1 drops. In this embodiment, the hinge 30 of the U-shaped guide 29 is opened by the rotation of the ejection disc 4, but details thereof will be omitted.

When the coin 1 drops, even if the handle 10 is rotated, the lever 26 further rotates in the direction of the arrow a and comes into contact with the stopper 34 to stop, and at the same time, the crank 32 is pulled up by the spring 32 and the gear 21 is pulled up. Since the gear 12 is disengaged from the gear 13, the rotational force of the handle 10 is not transmitted to the ejection disc 4. Therefore, the prize capsule 5 is not paid out.

According to the clutch structure of the above embodiment, it is possible to separately provide a coin authenticity discriminating device. In addition, the handle can be continuously rotated even after the prize is paid out, and the rotating force of the handle can be used for other purposes.
