BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a withdrawal device used in a cash register drawer or the like.

0002

[Prior Art] As a conventional example of a drawer device,
The structure of the device disclosed in Japanese Patent No. 311595 will be explained based on FIGS. 8 and 9. First, as illustrated in FIG. 8, this withdrawal device is a cash box 1 formed at the bottom of a cash register (not shown).
A guide rail 2 and a guide roller 3, which are elongated in the front-rear direction, are attached to both inner surfaces of the main body box 4, and the guide rollers 3 are attached to both outer surfaces of the drawer 5, which is slidably housed in the main body box 4. A guide rail 6 that engages with the guide rail 2 is formed, and a guide roller 7 that engages with the guide rail 2 is attached.

[0003]Furthermore, in this cash box 1,
A stopper guide 10 having a concave portion 9 formed of two convex portions 8 formed approximately at the center of the inner surface is attached to one inner surface of the main body box 4, and a stopper roller abuts against the inner surface of the stopper guide 10. 11 is attached to the outer surface of the drawer 5. Here, the stopper guide 10 is formed of a plate spring or the like and is supported inside the main body box 4 so as to be freely displaceable by its own elastic force, and as illustrated in FIG. roller 11
is designed to be removably locked.

In addition, in this cash box 1, a locking mechanism 12 that engages with the drawer 5 in a freely approaching and separating manner according to the control of the cash register main body, and a spring 13 that causes the drawer 5 to protrude are provided inside and rearward of the main body box 4. It is being

With this configuration, in this cash box 1, when the lock mechanism 12 is released and the drawer 5 is projected from the main box 4 by the elastic force of the spring 13, the stopper roller 11 is inserted into the recess 9 of the stopper guide 10. By locking, the drawer 5 is stopped midway. By doing this, the protruding drawer 5 is prevented from colliding with the worker's body, and the drawer 5 that is stopped in this state can be freely moved in and out manually.

[0006]

[Problems to be Solved by the Invention] In the cash box 1 described above, in order to temporarily stop the drawer 5 protruding from the main body box 4 midway, the stopper roller 11 of the drawer 5 can be freely engaged and detached from the recess 9 of the stopper guide 10. It is designed to be locked in place.

[0007] However, in this cash box 1,
As mentioned above, since the stopper guide 10 is made of an elastic material such as a plate spring so that the stopper roller 11 can be freely engaged and detached, the convex portion 8 may be worn out or deformed over time, causing the stopper guide 10 to deteriorate. Stopper roller 1 for recess 9 of
The locking of item 1 may be weak.

Furthermore, in this cash box 1, as described above, the elongated stopper guide 10 is formed of an elastic material and is supported in a movable manner.
The position of the stopper roller 11 may change, causing a failure in the locking of the stopper roller 11.

[0009] Therefore, in the above-described cash box 1, when the cash box 1 is used for a long period of time, the drawer 5 protruding from the main box 4 may not stop temporarily in the middle, reducing the durability and reliability of the device.

[Means for Solving the Problems] In a drawer device in which a drawer with an open top is inserted from the front into a main box with an open front and slidably stored therein, a guide roller is provided on one of the main box and the drawer. It is rotatably mounted, and a recess into which a part of the guide roller enters is formed on the other side when the drawer is opened by a predetermined amount, and the recess and the guide roller are elastically engaged by their own weight or an elastic body. I set it to match.

[0011]

[Function] The engagement between the guide roller provided in the main box and the drawer and the recess is such that a part of the guide roller enters, so aging changes such as wear and deformation of the recess are reduced. Since the drawer can be stopped in a partially opened state, the drawer will not collide with the operator when the drawer is opened, and the banknotes will not be exposed to a large extent.

Embodiment A first embodiment of the present invention will be explained based on FIGS. 1 to 4. Components that are the same as those described with reference to FIGS. 8 and 9 are designated by the same reference numerals, and description thereof will be omitted. First, in the drawer 14, which is the drawer device of this embodiment, as illustrated in FIG. and the recess 15 of the stopper guide 16
A stopper roller 17 that is removably engaged with the drawer 5 is attached to the outer surface of the drawer 5 via a support mechanism 18.

Here, as shown in FIG. 3, this support mechanism 18 connects one end of a plate spring 19 bent into a trapezoid and having the stopper roller 17 attached to the center thereof with a bolt 20 to the outer surface of the drawer 5. and fix the other end with a long hole (not shown).
It has a structure in which the stopper roller 17 is movably supported and pressed against the stopper guide 16 in a state where the stopper roller 17 is biased outward. .

In such a configuration, this drawer 14
Similar to the above-described cash box 1, the drawer 5 protruding from the main box 4 is stopped midway by the stopper roller 17 being engaged with the recess 15 of the stopper guide 16.

In this drawer 14, the stopper roller 17 is elastically supported by a support mechanism 18 so as to be removably engaged with the recess 15 of the stopper guide 16, and the stopper guide 16 is made of an elastic material. Since this is not necessary, changes over time such as wear and deformation of the recessed portion 15 of the stopper guide 16 are reduced. Moreover, with this drawer 14,
As described above, the stopper roller 17 is movable by the support mechanism 18, so the stopper guide 16 is fixedly installed inside the main body box 4, and the elongated stopper guide 16 is made of an elastic material and is movable. Since no support is required, there is no possibility that the position of the recessed portion 15 will change due to aging and that the stopper roller 17 will not lock properly.

Therefore, in this drawer 14, the durability and reliability of the mechanism for temporarily stopping the drawer 5 protruding from the main body box 4 are improved.

In this embodiment, the drawer 14 is illustrated in which the recess 15 is formed by curving the stopper guide 16, but the present invention is not limited to the above structure.
As illustrated in FIG. 4, it is also possible to implement a drawer device (not shown) in which a pseudo recess 22 is formed by cutting out a part of the stopper guide 21.

A second embodiment of the present invention will be explained based on FIGS. 5 to 7. The same parts as in the previous embodiment are designated by the same reference numerals, and the description thereof will be omitted. In this embodiment, a guide roller 3 is rotatably attached to the inner surface of the main body box 4, and the guide roller 3 is attached to the upper edge 23 of a guide rail 6 that is engaged with the guide roller 3, with the drawer 5 being opened by a predetermined amount. A recess, that is, a notch 24, into which a portion of the roller 3 fits is formed.

In such a configuration, the guide roller 3
, the upper edge 23 of the guide rail 6 of the drawer 5 is in pressure contact with the drawer 5 due to its own weight, and when the locking mechanism 12 is activated by the drawer opening command, it moves forward by the force of the spring 13. When the drawer 5 is opened a certain amount, the guide roller 3 engages with the notch 24 and the drawer 5 is stopped. Therefore, even if the opening speed is high, the opening dimension is small, so there is no possibility of collision with the operator. Moreover, the banknote storage section is not left wide open and is safe. When it is necessary to open the drawer 5 wide, the guide roller 3 is removed from the notch 24 by lifting the tip of the drawer 5 a little while pulling it out, thereby making it free and opening the drawer 5 wide.

Next, what is shown in FIG. 7 is a modified example,
An inclined portion 25 is formed at the edge of the notch 24. Therefore, the drawer 5 should be fully opened while having a sufficient function of stopping the drawer 5 at a certain position, and
The drawer 5 can be easily closed.

[0021]

Effects of the Invention As described above, the present invention provides a drawer device in which a drawer with an open top is inserted from the front into a main box with an open front and is housed in a slidable manner. Since a roller is rotatably attached to one side and a recess is formed on the other side to engage the roller at a position where the drawer is opened by a predetermined amount, the engagement between the roller provided in the main box and the drawer and the recess is as follows. Since a portion of the roller is inserted into the recess, aging such as wear and deformation of the recess is reduced, and this allows the drawer to be stopped when it is opened halfway, so when the drawer is opened, the drawer cannot be opened by the operator. This has the advantage that the banknotes will not collide with each other, and the banknotes will not be exposed to a large extent.
