Description

[Detailed Description of the Invention] Technical Field The present invention relates to a withdrawal device used in electronic cash registers and the like used for sales management and money management in stores and the like.

BACKGROUND ART A drawer device generally includes a drawer and a drawer receiver that receives the drawer. When this withdrawal device is used in an electronic cash register, the drawer corresponds to a cash register, and the withdrawal receiver corresponds to the main body of the electronic cash register. Hereinafter, in order to simplify the explanation, an example of an electronic cash register will be explained.

Conventionally, the cash box of an electronic cash register has a movable part in which money is stored and a fixed part that houses the movable part, and the movable part is moved by the elastic force of a spring provided in the fixed part. I'm letting you do it. Therefore, depending on the amount of money stored in the moving part,
The moving speed of the moving parts changes. Therefore, when the amount of money is small, the movable part may hit the operator's body strongly. Furthermore, it is difficult to appropriately determine the moving speed of the movable part.

Purpose An object of the present invention is to provide a drawer device that can prevent the drawer from protruding from the drawer holder at high moving speeds.

Structure of the invention The present invention comprises a drawer, a drawer receiver for receiving the drawer, and a first drawer provided in the drawer receiver and acting in a direction to cause the drawer to pop out outward from the drawer receiver.
A spring 10, a protrusion 2 formed on the drawer, and a pin 6a that is connected to the drawer holder for angular displacement, one end of which comes into contact with the protrusion 2 when the drawer moves outward, and the protrusion 2 a coiled second lever 4 which is connected at one end to the lever 4 and urges said one end of the lever 4 towards the drawer;
a spring 5; and a plurality of hook portions 9 provided on the drawer holder and spaced apart along the moving direction of the drawer.
a, 9b, 9c, and the other end of the second spring 5 is selectively hooked on one of the hook parts 9a, 9b, 9c.
9b and 9c.

Function According to the present invention, the first spring 10 is provided in the drawer holder, the first spring acts in a direction to cause the drawer to pop out outward, the protrusion 2 is formed on the drawer, and the protrusion 2 is formed on the drawer. The one end is biased toward the drawer by the second spring 5, so that when the drawer moves outwardly, the one end of the lever 4 contacts the protrusion. Climb over the protrusion 2. This prevents the drawer from projecting outwards at high speeds of movement. Therefore, the drawer does not collide with the operator's body with great force, and is safe.

Further, in the present invention, one end of the second spring 5 is connected to the lever 4, and the other end is selectively pulled to one of the plurality of hooks 9a, 9b, and 9c provided on the drawer receiver. I made it so that it can be hung,
The force with which one end of the lever 4 contacts the protrusion can be adjusted. Therefore, it becomes possible to adjust the speed at which the drawer moves outward.

Furthermore, according to the present invention, the second spring 5 is coil-shaped, and existing commercially available springs can be used, making it easy to mass-produce.

Embodiment FIG. 1 is a block diagram of an embodiment of the present invention, and FIG. 2 is a block diagram showing a state in which the movable part 1 is moved in the direction of arrow A. A protruding part 2 is provided on the side surface of the movable part 1 of the cash box. This movable part 1 is normally housed in a fixed part 8, and is moved in the direction of arrow A by the spring force of a spring 10 when a command to open the cash box is issued. The lever 4 is rotatably fixed to the fixed part 8 by a pin 6a. A roller 3 is rotatably fixed to the lever 4 by a pin 3a, and one end of a spring 5 is fixed to the lever 4 by a pin 5a. One end of a hook 7 is fixed to the other end of the spring 5, and the other end of the hook 7 is hooked into a hole 9b provided in the fixing part 9 and fixed. The lever 4 rotates clockwise about the pin 6a by the elastic force of the spring 5, but is biased by the projection 6 provided on the fixing part 8 at the position shown in the figure and stops. When the hook 7 is hooked on the other hole 9a, the spring bias on the lever 4 increases, and when the hook 7 is hooked on the hole 9c, the spring bias on the lever 4 is decreased.

When the movable part 1 moves in the direction of arrow A in response to a command to open the cash box, the protruding part 2 hits the roller 3 on the way, and the roller 3 attempts to push the protruding part 2 away. At this time, as the spring 5 provided on the lever 4 expands and contracts, the roller 3 moves under pressure. When the protruding part 2 passes over the roller 3, the movable part 1 is already slowly moving in the direction of the arrow A in a decelerated state and obtains the effect of two-stage deceleration. When the operator closes the movable part 1 of the cash box after depositing and withdrawing money, the protruding part 2 comes into contact with the roller 3 again. At this time, the roller 3 and lever 4 are configured to move only in the direction of arrow B due to the protrusion 6. In this way, the movable part 1 returns to its original state, and the cash box becomes closed.

In order to adjust the deceleration effect of the movable part 1, a hook 7 is provided at one end of the spring 5, and the hook 7 is hooked into a plurality of holes 9 made in the fixed part 8, and the spring pressure is adjusted by changing the hole position. is possible.

As described above, according to the present invention, one end of the lever 4 contacts and climbs over the protrusion 2 formed on the drawer, so that the drawer is prevented from protruding outward at a large movement speed. Therefore, the body of the drawer operator etc. will not be collided with a large force and is safe.

Moreover, in the present invention, the other end of the second spring 5, whose one end is connected to the lever 4, can be selectively pulled to one of the plurality of hooks 9a, 9b, and 9c provided on the drawer receiver. Since it is hung, it is possible to adjust the force with which the one end of the lever 4 and the protrusion come into contact with each other, thereby making it possible to adjust the moving speed of the drawer. This makes it possible to realize a drawer device that is easy to use.

Furthermore, according to the invention, the second spring 5 is coiled and is therefore commercially available;
Excellent for mass production.
