η.

[Industrial Field of Application] The present invention relates to a payout device such as a banknote deposit/withdrawal device, and more particularly to an improvement in the structure of a shutter opening/closing mechanism of a payout section for banknotes, etc.

Banknote deposit/withdrawal devices are used as part of streamlining counter operations at banks and other financial institutions, and shacks are installed at the slots of bill deposit/withdrawal devices where customers can deposit and withdraw banknotes themselves. A mechanism is used to open and close this shutter.

The current mechanism for opening and closing shutters uses a mechanism that opens and closes by driving one end of the shutter, so the shutter does not operate smoothly, and when it is closed, there is a problem in which the shutter cannot be placed in the correct position. ing.

Under the above circumstances, there is a need for a shutter opening/closing mechanism that can smoothly open and close the shutter and can position the shutter at an accurate position in the closed state.

[Conventional technology]

A conventional shutter opening/closing mechanism will be explained with reference to FIG.

As shown in the plan view of FIG. 2 (al), the conventional shutter opening/closing mechanism has an oblong hole 21a at one end of the shutter 21, and a stand 2 that engages with the oblong hole 21a at the tip. The lever 3 is provided so as to share a rotation center with the gear 4.

The tip of the lever 3 is bent outward, and the stand 2
is provided at the tip thereof, and is placed at the right end of the oblong hole 21a, so that even if the shutter 21 is attempted to be moved downward in the figure, that is, in the opening direction, the shutter cannot be moved. .

Both sides of the shutter 21 are bent downward, and two groove rollers 5 are provided at the bent portion on the side where the oblong hole 21a is provided, as shown in the figure, and a round rail 6 provided on the main body is provided.
It has a structure that allows you to slide on it.

As shown in the left side view of FIG. 2 (bl), the bent portion on the opposite side has a structure in which the shutter 21 is moved to open and close by the rotation of four rollers 7 provided on the main body.
The fully open position of the shutter 21 is detected by the optical sensor 17 and the drive is stopped.

As shown in the side view of FIG. 2 (C1), shutters 1 to 8 are provided on both sides of the shutter 21.
It has a structure that restricts vertical and horizontal movement of the shutter 21.

With this structure, the shutter 21 can be moved by the stand 2 that engages with the oblong hole 21a at one end of the shutter 21 as shown in FIG. 2 (Fl).
In the plan view, the shutter 21 is moved downward to open the inlet until it reaches the position of the optical sensor 7, and then moved upward to close the inlet. Since this is done only on one side, it is difficult to open and close smoothly and various problems occur.

[Problem to be solved by the invention]

In the conventional shutter opening/closing mechanism described above, the shutter is driven by only one side of the shutter, and the roller has a structure that only supports the weight of the shutter and cannot regulate the left and right sides. Since this is done using only the grooved rollers and round rails, there is a problem that the shutter does not open and close smoothly, and the top cover and shutter may come into contact and rub. There has been a problem in that the shutter stop position is inaccurate due to play between the two, and a gap is created on the opposite side of the diagonal line farthest from the shutter drive position when the shutter is closed.

The object of the present invention is to provide a shutter opening/closing mechanism that can be installed simply and easily under the following circumstances, and that can smoothly drive the shutter and stop it at an accurate position. It is.

[Means to solve the problem]

The shutter opening/closing mechanism of the present invention includes a shutter having a plurality of oval holes, a lever having a stand that engages with one of the oval holes, and a gear sharing a rotation center with the lever.
A gear that meshes with this gear and shares an intermediate shaft with the pulley,
Hel 1-, which transmits the rotation of this pulley to other pulleys;
The lever is configured to include a lever that rotates about the axis of the pulley, and a stud that is provided at the tip of the lever and engages with the other oblong hole provided in the shutter.

[Effect]

That is, in the present invention, as shown in FIG.
A gear 4 is provided which shares the center of rotation with the lever 3 which has been rotated.

A gear 9 that meshes with the gear 4 is provided, and the gear 9 and the pulley 11 are connected by an intermediate shaft 10.

On the other hand, a slider pulley 13 is provided which shares a rotation center with a lever 15 having a stand 16 at its tip which engages with the other oblong hole 1b of the shutter 1.

Since the pulley 13 and the pulley 11 are connected by a belt 12, when the gear 4 is rotated in the direction of the arrow shown in the figure, the lever 3 is rotated and the shutter 1 is moved as shown in the figure by the connection between the stud 2 and the oblong hole 1a. At the same time as it moves downward, this rotation is transmitted to the stand 16 via the gear 9, the intermediate shaft 10, the pulley 11, the lever 12, the pulley 13, the shaft 14, and the lever 15, and the stand 16 and the oval The connection of the holes 1b makes it possible to move the shutter 1 to the lower blade in the figure.

〔Example〕

An embodiment of the present invention will be described below with reference to FIG.

A plan view of an embodiment of the present invention is shown in FIG. 1 (al), and a side view is shown in FIG. 1 fbl.

As shown in Fig. 1 (al), the shutter has a first plurality of oval holes 1a and 1b, and the lever 3, which has a stud 2 at its tip that engages with one of the long holes P] 7Lla, and the center of rotation are connected to each other. A shared gear 4 is provided, and a gear 9 that meshes with this gear 4 is provided.

Next, as shown in FIG. A lever 15 is provided with the pivot point 14 of this pulley 1 as the center of rotation, a stud 16 is provided at the tip of this lever 15, and this stan F'1G is inserted into the other oblong hole 1b of the shack 1. I agree with that.

With this configuration, when the gear 4 is rotated in the direction of the arrow shown in the figure, the lever 3 is rotated and the stud 2 and the oblong hole 1d are connected to move the shutter ■ downward in the figure. At the same time, this rotation causes gear 9, intermediate shaft lO
, is transmitted to the stand 16 via the pulley 11, belt 12, pulley 13, shaft 14, lever 15, and the stud 1
6 and the oblong hole 1b, it becomes possible to move the shutter l downward in the figure.

This synchronized engagement between the two sets of studs and the oblong hole makes it possible to move the shutter by driving both ends of the shutter, allowing for smooth opening and closing of the shutter and accurate positioning. This makes it possible to stop the shutter.

Furthermore, in the past, the opening of the Nyatta was prevented only by the engagement between one stand 2 and the oblong hole 21a, but in the present invention, the stands on both sides and the oblong hole are secured. It is possible to stably prevent the shutter from opening.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, by using a shutter opening/closing mechanism with an extremely economical structure, it is possible to smoothly and accurately perform the opening/closing operation of the shutter, and it is possible to stably prevent the shutter from opening. It is possible to provide a shutter opening/closing mechanism that can be expected to significantly improve reliability.
