Description

DETAILED DESCRIPTION OF THE INVENTION [Technical field of BJ] The present invention relates to a structure for preventing paper jamming in a coin return slot.

[Prior art]

For example, public telephones, vending machines, etc. are equipped with coin storage devices, and are configured to make it possible to make calls or take out products by sorting and collecting inserted coins.

The above-mentioned coin storage device is provided with a coin return mechanism that returns selected defective coins and spurious coins and returns surplus coins after the operation of the main device is completed.

This coin return mechanism consists of a coin return track that is continuous with the coin sorting mechanism and the coin return track, and a coin return port that is provided at the lower end of this track and opens to the side of the casing. is normally closed by a flapper that can be opened and closed inward, and the user can push the flapper open inward to take out the returned coins stored inside.

By the way, in the conventional structure of the coin return opening of the above-mentioned coin return mechanism, returned coins are temporarily stored by stuffing paper, etc. at the back of the coin return opening, especially at the open end of the return track, and then the coins are stolen. This sometimes led to the death of the emperor who stole the garden. In particular, such problems are serious in equipment and devices intended for export, and it is necessary to take appropriate countermeasures.

This can be briefly explained using the conventional example shown in Fig. 1.
The coin return port indicated by the reference numeral 1 in the figure is equipped with a coin return container 4 disposed below the coin return track 3 in the main equipment casing 2, and this container 4 is attached to the inner surface of the casing 2. It is fixedly installed and a part of the front part is on the side of the housing (generally the lower front side of the housing 2).
It is opened to The opening 5 is shaped so that it can be opened and closed within the container 4 by a flapper 6 whose upper part 6a is rotatably supported inwardly by a support shaft T. is wound around the support shaft 7 and is normally biased in the closing direction by a spring 8.

However, according to the conventional structure described above, the coin return container 4 has a coin return track 3 provided inside the housing 2 at a certain distance, and also has a function to temporarily store coins to be returned and a flapper. In order to ensure the push-open operation of the flapper 6, it has a slightly wider volume space with depth, and when the flapper 6 is pushed open from the outside as shown by the phantom line in the figure The back side of container 4, especially the hard part:
? This made it possible to commit malicious acts such as theft by stuffing paper or the like into the open end of the j-return track 3.

As a coin return 1 yen structure that can prevent such paper jamming, etc., for example, as disclosed in Japanese Utility Model Application Publication No. 57-161083, a shielding door that is rotated in conjunction with this is provided inside the Fuji brim. Conventionally, there have been proposed devices in which the coin return path can be shielded with this shielding door. However, in such a conventional structure, since the opening amount of the flapper is small, it is necessary to have a large coin reservoir near the opening so that coins can be easily taken out, which increases the depth of the container. This becomes a big obstacle in making the installation space within the main equipment more efficient and downsizing it, and there is a desire for a more practical structure to prevent paper jamming.

[Summary of the invention]

The present invention has been made in view of the above-mentioned circumstances.The present invention has been made in view of the above-mentioned circumstances. With a simple structure that allows the flapper to engage and rotate, the return track is closed by the shutter when the flapper is in motion, thereby preventing paper jamming and reducing the risk of theft or tampering. The present invention provides an inexpensive structure for preventing paper jamming in the coin return slot, which can prevent unusability of the device and problems that occur when the machine is unusable. This will be explained in detail.

Figures 2 to 4 (a) and 4 (b) show an embodiment of the paper jam prevention structure of the coin return slot according to the present invention. The hidden parts are given the same numbers and their explanations are omitted.

Now, according to the present invention, the shutter 10 that can open and close the lower end D+10 end of the coin return track 3 facing the upper end on the back side of the coin return container 4 can be rotated in a direction perpendicular to the flapper 6. support and this shutter 10 with 72 brim 6

Together with the seven flaps 6, they are urged in the closing direction by a spring 15. Then, the arcuate surface portion 1 of this engaging member 14
A pair of retaining grooves 16.16 are provided as retaining portions along the opening/closing direction of the flapper 6 at positions corresponding to the engaging protrusions 10b, 10b on the outer surface of the shutter 10.10 when the shutter 10.10 is in the closed state. is formed. These retaining grooves 16.1
6 has one end opening at the side edge of the shutter 10 and 10, and has a length corresponding to the amount of rotation of the flapper 60.

In addition, in the figure, 17 is a stopper piece protruding from the inside of the return container 4, and 6b is a stopper piece that is engaged with the stopper piece 6b to close the flapper 6.
In this embodiment, a notch 14d etc. is formed so that the front end of the engaging member 14 engages with the back surface of the seven flap 6.

In such a configuration, the flapper 6 is normally operated as shown in FIGS. 3(a) and 4(a).
The opening 5 of the container 4 is closed, and at this time the engaging member 14 is also urged toward the opening 5 by the spring 15 together with the flapper 6. Further, the shutters 10, 1θ are opened by their own weight so that their engaging protrusions 1Qb, 10b are in contact with the rear side edge of the engaging member 14. Of course, a spring or the like may be provided to bias these shutters 10, 10 in the opening direction.

On the other hand, when the flapper 6 is pressed inward and opened, the retaining portion 14 is also rotated in conjunction with this, and the retaining protrusion 10b is engaged with the rear side edge of the flapper 6.

The shutter 0.10 is rotated in the closing direction by the shutter 10b. At this time, the retaining protrusions 10b of these shutters.

The engagement position between 10b and the rear side edge of the engaging member 14 is at the fourth position.
As shown in the center of the figure (,), it moves toward the center. These engaging protrusions 10b, 10b engage D' of the retaining portion wing 14 when the shutter 0.10 is in the closed state.

〔Effect of the invention〕

As explained above, according to the paper jam prevention structure of the coin return slot according to the present invention, the shutter that engages with the flapper to open and close the lower end frontage of the coin return track is rotated in a direction perpendicular to the flapper. Since the structure is movably supported, the return track is closed with a shutter when the flapper opens, and this prevents paper from being stuffed into this area, thereby preventing theft accidents. It can be prevented, and
Since the rotation directions of the flapper and shutter are different, the internal space can be increased, making the whole device smaller and more compact, and it can also be easily applied to existing models without major design changes. Furthermore, even if there is a change in the connection part with the return track side, it can be easily dealt with, and has various excellent effects.

Further, according to the present invention, the bottom of the member that is integrally provided on the side of the seventh flap and engages with the shutter is formed into an arcuate surface, and the retaining portion that does not interfere with the opening and closing of the seventh flap is formed on this arcuate surface. In addition to the above-mentioned effect, by forming the flapper, it is possible to prevent troubles such as paper stuffing on the back side of the flapper, and this has a great effect in guaranteeing the operation of the main equipment.
