Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an opening / closing mechanism for a cash box used as a cash register and various other cash management machines.

[0002]

[Prior Art]

 Conventionally, this type of cash box is composed of a drawer portion 12 for storing money and a cash box body 11 for housing the drawer portion 12 as shown in FIGS. 5 (a) and 5 (b). The drawer is locked in the main body by the locking mechanism. When this locking mechanism is released, the rail 14 of the drawer 12 slides on the roller 13 by the restoring force of the coil spring 17 and is pushed out. The left and right protrusions 15 provided on the outer surface 12b of the bottom plate of the drawer 12 collide with the two left and right leaf springs 16 provided on the inside of the bottom surface of the cache box body 11, respectively, so that they are in the normal position. The leaf spring 16 has a mechanism to stop by bending and pressing the convex portion 15.

[0003]

[Problems to be solved by the device]

 With such a conventional cash box opening / closing mechanism, the drawer must be stopped once during the movement to the open state. This is convenient, for example, when inserting and removing only coins, but it is not preferable when frequently inserting and removing banknotes stored in the rear portion of the drawer. However, in order to avoid this stop, it takes time and effort to remove the leaf spring that constitutes the opening / closing mechanism, and there is a drawback that it cannot be done easily.

[0004]

[Means for Solving the Problems]

 In the opening / closing mechanism of the cash box of the present invention, a female screw is provided on the bottom plate of the cash box main body substantially below the center of the leaf spring, and the female screw is engaged with the female screw and the tip of the leaf spring presses the leaf spring from below. The feature is that a thumbscrew that can change the deflection height is provided.

[0005]

[Action]

 By turning the knob of the thumbscrew protruding downward from the bottom plate of the cash box body and advancing the screw by a prescribed amount, the tip of the thumbscrew presses the leaf spring and bends the center of the leaf spring upward by a prescribed amount. You can This allows the leaf spring to collide with the convex portion on the outer surface of the bottom plate of the drawer portion while the drawer portion is moving, and stop the drawer portion during the full opening. If the knob is turned in the opposite direction and the screw is retracted and placed, the collision can be avoided during movement of the drawer, and the drawer can be switched to a fully open system without stopping halfway.

【Example】

 Next, an embodiment of a cash box opening / closing mechanism of the present invention will be described with reference to the drawings.

FIG. 1 is a partially cutaway plan view showing an embodiment of a cash box opening / closing mechanism of the present invention.

FIG. 2 is a partially cutaway side view of FIG. 1, and FIG. 3 is a partially broken front view of FIG.

FIG. 4A is a partially cutaway side view showing the open state of the drawer portion 2 of FIG. 2, and FIG. 4B is a bottom plate outer surface 2 b of the drawer portion 2 of the leaf spring 6 of FIG. 4A. 4C is a partially enlarged view of the case where it is in contact with the convex portion 5 provided in FIG. 4, and FIG. 4C is a partially enlarged view of the case where the leaf spring 6 and the convex portion 5 of FIG. 4A are not in contact.

As shown in FIGS. 1 to 3, in the present opening / closing mechanism, rails 4 provided on both sides of a drawer 2 for storing money slide on a roller 3 attached to a cash box body 1. By moving, the drawer 2 moves horizontally with respect to the main body 1 in the direction of arrow A. The compression coil spring 7 is mounted between the spring receiver 1a fixed to the cash box body in a compressed state and the rear surface 2a of the drawer portion so as to constantly push the drawer portion 2 in the direction of the arrow B, that is, in the open state. There is. Further, in order to hold the drawer portion 2 in a closed state against the pressing force of the coil spring 7, a locking projection 2c is provided on the rear surface 2a of the drawer portion 2, and inside the cash box body 1, A locking mechanism 8 including an electromagnet 8a, a locking portion 8b, a swinging portion 8c and a cam portion 8d is provided.

On the outer surface 2b of the bottom plate of the drawer portion 2, rigid convex portions 5 are provided at two places on the left and right. Inside the bottom surface of the cash box body 1, two leaf springs 6 are provided on the left and right, and their positions are directly below the passage of the projection 5 when the drawer 2 moves. Furthermore, a female screw 1b is provided on the bottom plate of the cash box main body 1 substantially at the center of the leaf spring 6 so that the convex portion 5 and the leaf spring 6 can be engaged at a predetermined position when the drawer portion 2 moves. There is provided a thumbscrew 9 which can be screwed into the bottom plate, penetrates the bottom plate, and presses the leaf spring 6 to change the deflection height of the leaf spring 6. A lock nut 9a (see FIGS. 4B and 4C), a bending lever (not shown) attached to the knob, or the like can be considered as the loosening prevention means of the knob screw 9.

Next, the operation of this mechanism will be described. When the knob screw 9 is pinched and turned and the screw 9 is advanced by a predetermined amount, the tip of the screw 9 presses the leaf spring 6 to bend it by a predetermined amount. Thereby, the leaf spring 6 collides with the convex portion 5 of the bottom plate outer surface 2 b of the drawer portion 2 while the drawer portion 2 is moving, and the drawer portion 2 can be stopped on the way to full opening. (Hereinafter, this state will be referred to as the first open state.) If the knob is turned in the opposite direction and the thumbscrew 9 is retracted, this collision does not occur, and thus the drawer 2 stops halfway. Without doing so, it is possible to switch to a method in which the maximum open state can be achieved at once.

The locking mechanism 8 and the coil spring 7 are generally used. When the locking mechanism 8 that was operating in the closed state of the pull-out portion 2 is released, the restoring force of the coil spring 7 pushes the pull-out portion 2 from the rear surface 2a, so that the rail 4 on the side surface thereof is rolled by the roll 3 Glide up to open. At that time, as described above, it is possible to select a desired one of the two methods as to whether or not the drawer portion 2 is fully opened at once by the operation of the knob.

Further, with reference to FIGS. 4A to 4C, the setting of the coil spring 7 and the leaf spring 6 will be described in detail.

The restoring force of the coil spring 7 is set to an appropriate strength, and the bending height of the two leaf springs 6 provided inside the bottom surface of the cash box body 1 is increased by advancing the thumbscrew 9, It is so arranged as to come into contact with the convex portion 5 provided on the outer surface 2b of the bottom plate of the drawer portion 2. In order to reliably maintain this contact, the above-mentioned lock nut 9a is provided and is operated. As a result, the operation of the rail 4 sliding on the roll 3 is stopped by the leaf spring 6 pressing the convex portion 5. That is, the drawer portion 2 once stops at this position and becomes the first open state (see FIG. 4B). Next, in order for the convex portion 5 to get over the leaf spring 6, it is necessary to apply a force larger than the restoring force of the coil spring 7 which is adjusted in advance. In other words, the restoring force of the coil spring 7 is set to the lower limit of the force that pushes out the pull-out portion 2 until the convex portions 5 come into contact with the leaf springs 6, respectively, and the convex portions 5 get over the leaf springs 6. It should be set within the range with the maximum extruding force as the upper limit. Therefore, it is possible to set a large allowable range for the weight of the money receiving portion in the drawer portion 2 and the variation of the restoring force of the coil spring 7, and to make the drawer portion 2 in the first opening regardless of the amount of the stored items. You can surely open up to the state.

Further, the moving distance of the drawer portion 2 to the first open state can be arbitrarily set by the positional relationship between the position of the convex portion 5 and the leaf spring 6. Further, in the first open state, if the operator pulls the drawer portion 2 by hand, the convex portion 5 can get over the leaf spring 6, so that the drawer portion 2 can be easily pulled out to the maximum open state. is there. When the drawer portion 2 is closed, the operator manually pushes the drawer portion 2 so that the convex portion 5 again rides over the leaf spring 6 and retracts to a predetermined position, and the locking mechanism. It is held closed by 8.

When it is desired to move the drawer portion 2 between the closed state and the maximum opened state at once, it is already sufficient to retract the knob screw 9 so that the leaf spring 6 and the convex portion 5 do not come into contact with each other. As mentioned above.

[0018]

[Effect of the device]

 As described above, according to the present invention, a female screw is provided on the bottom plate of the cash box body, and a knob screw for screwing the female screw on the bottom plate of the cash box main body presses the leaf spring on the inside of the bottom surface. It is possible to arbitrarily select and operate either the method of stopping at or the method of performing all opening and closing operations all at once, and it is possible to easily switch this selection, so that the cash box can be efficiently operated as desired. There is an effect that can be operated.
