Description

[Detailed description of the invention] (a) Industrial application field The present invention mainly relates to a drawer device used in a cash register.

(B) Prior Art In a drawer device used in a cash register, for example, as disclosed in Japanese Utility Model Application Publication No. 174686/1980, guide rails are provided on both inner surfaces of the lower case, and an arm protruding from the rear side of the body of a coin storage box that is inserted and removed from the lower case is provided with rollers that are guided by the guide rails. In most cases, however, the rollers can be inserted above the guide rails of the lower case. Therefore, if the rollers are mistakenly inserted above the guide rails, there is a risk of damaging the guide rails and the inner surface of the top plate of the lower case, and there are problems such as the rollers being difficult to remove if pushed in forcefully.

(c) Purpose of the invention The purpose of the invention is to prevent incorrect insertion of a drawer into the upper part of the rail.

(d) Structure of the invention The structure of the invention is to have a rail with a roughly U-shaped cross section and guide grooves formed on both side walls of a box body that has a storage chamber inside and is open at the front. The drawer is fixed facing each other, and is detachably inserted into the storage chamber through the opening, and has an arm pivoted to the rear of the drawer provided with a drawer case, with rollers rotating in the guide groove facing rearward. In the projecting type, the front end of the upper wall of the rail is bent upward so that the distance between the end and the top surface of the storage chamber is smaller than the vertical width of the arm, and the distance between the upper wall is adjusted to the distance between the arms. It is made by making the interval smaller than that of .

(e) Effect When inserting a drawer into the storage chamber, even if you try to insert the drawer arm between the rail and the storage chamber top plate, the distance between the front end of the upper wall of the rail and the storage chamber top plate will be smaller than the vertical width of the arm. This configuration ensures that the above-mentioned erroneous insertion is prevented.

(F) Embodiment First, an embodiment of the present invention will be explained based on FIG. 1. 1 is a drawer device used for a cash register, and a box 4 has a storage chamber 3 with an opening 2 at the front.
It mainly consists of a drawer 5 which can be put in and taken out from the opening 2 in the storage chamber 3 of the box body, and a ring-shaped hook 6 is installed at the rear approximately in the center of the rear plate 5' of the drawer. A locking mechanism 7 is fixed to the bottom plate 4' of the box body 4 in a position opposite to this hooking metal fitting. In the storage section 8 of the drawer 5, a drawer case 10 made of resin and having a plurality of storage grooves 9, 9, . . . for storing various types of money is removably stored.

Also, on both side walls 4'', 4'' in the storage chamber 3, a second
As shown in the figure, a pair of rails 12, 12 with guide grooves 11, 11 integrally formed by bending a band-shaped sheet metal into a substantially U-shaped cross section are fixed with the guide grooves 11, 11 facing each other. There is.

On the other hand, rollers 13, 1 rolling in the guide grooves 11, 11 at the tips are provided on both sides of the rear of the drawer 5.
A pair of arms 14, 14 which are pivotally connected to each other are opposed to each other and protrude rearward.

And the upper walls 15, 15 of the rails 12, 12
As shown in FIG. 5, the front ends 15', 15' have a distance C between the ends and the top surface 4 of the storage chamber 3.
It is bent upward so that it is smaller than the vertical width d of the arms 4 and 14, and the distance b between the upper walls 15 and 15 is narrower than the distance a between the arms 14 and 14.

The locking mechanism 7 is mainly composed of a cam plate 16 which is rotationally driven by a hook 6 when the drawer 5 is pushed in and locks the drawer 5 in the pushed position, and a plunger 17 which releases the lock of the cam plate. It is composed of

When attaching or detaching the drawer 5, when the drawer 5 is removed from the storage chamber 3 of the box body 4 as shown in FIG. This is done by inserting it into 11.
On the other hand, if the tips of the arms 14, 14 are mistakenly inserted into the space above the rails 12, 12 as shown in FIG.
The distance b between the upper walls 15, 15 of the rails 12, 12
In addition to setting it larger than rail 12,
The distance c between the front ends 15', 15' of the upper walls 15, 12 of 12 and the top surface 4 of the storage chamber 3 is determined by
Because it is formed to be shorter than the vertical width d of
15' and prevents insertion deeper than this.

(g) Effects of the invention The structure of the invention prevents the arm provided at the rear of the drawer from being incorrectly inserted into the space above the rail, prevents damage to the box, rail, arm, etc. due to incorrect insertion, and prevents damage to the box, rail, arm, etc. due to incorrect insertion. There is no need to separate the drawer device and the cash register in order to remove the drawer.
