Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to the structure of a cash register, and more particularly to one that facilitates function switching and maintenance of electronic circuits housed inside.

[Conventional technology]

Conventionally, there have been devices of this type as shown in FIGS. 1 and 2. In FIGS. 1 and 2, 1 is a chassis, 2 is a sub-chassis, and 3 is a cash box, and the sub-chassis 2 is fixed to this cash box 3. 4 is a front panel, which is screwed to chassis 1; 5 is a screw, and the chassis 1 is attached to the sub-chassis 2 with this screw 5. Reference numeral 6 denotes an electronic circuit, which is housed within the subchassis 2.

In such a device, by removing the front panel 4, loosening the screws 5, and removing the chassis 1, functions of the electronic circuit 6 can be changed and maintenance can be performed depending on the purpose of use.

[Problem that the invention seeks to solve]

Since the conventional cash register is constructed as described above, in order to change the function or perform maintenance on the electronic circuit 6 housed in the sub-chassis 2, the screw 5 is removed and the chassis 1 is removed. After the switching and maintenance are completed, it is necessary to attach the chassis 1 to the sub-chassis 2 using the screws 5, which takes time. Particularly when a breakdown occurs, a quick response is desired, but this requirement has not been met.

SUMMARY OF THE INVENTION An object of the present invention is to provide a cash register that can quickly perform function switching and maintenance of electronic circuits, and can protect electronic circuits by having a dust-proof and drip-proof structure.

[Means to solve problems]

The cash register according to the present invention has a chassis connected to one end of a subchassis by a hinge,
A locking mechanism is provided at the other end to lock the subchassis and the chassis, and the locking mechanism can be locked and unlocked from the front of the cashbox by removing a trolley that is detachably installed in front of the cashbox. It is something.

[Effect]

In the cash register of this invention, by unlocking the lock mechanism, the chassis can be opened around the hinge, and after locking, the electronic circuit can be accessed from the outside by attaching the drawer to the cash register. It is designed to be sealed tightly.

An embodiment of the present invention will be described below with reference to the drawings. In FIGS. 2, 3, and 4, 7 is a drawer, which is housed in the cash box 3 and can be easily attached and detached. 8 is a sub-chassis fixed to the storage frame of the drawer 7, and 9 is a hinge, which connects the chassis 1 and the sub-chassis 8, and the chassis 1 can be opened by lifting the hinge 9 as a fulcrum. 10 is a stay that prevents the chassis 1 from opening too much when lifted and opened, and
Its role is to keep it open. 11
is a guide pin that is fixed to chassis 1.
Reference numeral 12 denotes a lock, which together with the guide pin 11 constitutes a lock mechanism. When the lock 12 is slid with the chassis 1 closed, the lock 12 catches on the guide pin 11 as shown in FIGS. 5 and 6, so that the chassis 1 can be easily fixed to the sub-chassis 8. . 13 is a spacer, which is fitted into the elongated hole 12c of the lock 12.
The movement of 2 is restricted. 14 is a spring that applies a load to the lock 12;
is prevented from moving by vibration, etc. 15 is a screw for fixing the spacer 13 to the sub-chassis 8.

In order to open the chassis 1 in such a device, the following procedure is used. First, pull out the drawer 7 and remove it from the cash box 3. Next, insert your finger into the hole where the drawer 7 was housed in the cash register 3, and slide the 12b portion of the lock 12 protruding into the cash register 3, so that the lock 12 locks into the guide pin 11.
It deviates from the When the chassis 1 is lifted in this state, the stay 10 works and the chassis 1 can be opened.

Further, when the chassis 1 is closed and locked with the sub-chassis 2 and the trolley 7 is attached to the cash box 3, the electronic circuit 6 is sealed from the outside. Therefore, the electronic circuit 6 can be protected from dust, water droplets, etc.

〔Effect of the invention〕

As described above, according to the present invention, the chassis can be easily opened without tools, so the functions and maintenance of the electronic circuits housed inside can be quickly performed. It has the effect of protecting the circuit.

[Brief explanation of drawings]

Fig. 1 is an exploded perspective view showing the structure of a conventional cash register, Fig. 2 is a perspective view showing the external appearance of a cash register common to the conventional cash register and an embodiment of the present invention, and Fig. 3 is an embodiment of the present invention. In the perspective view showing an example, I shows the state where the chassis is not lifted.
Figure 4 is an enlarged sectional view taken along the - line in Figure 3, Figure 5.
The figure is a top view of FIG. 4, and FIG. 6 is a side sectional view A and a plan view B showing the relationship between the guide pin and the lock. In the figure, 1 is a chassis, 3 is a cash box, 7 is a drawer, 8 is a sub-chassis, 9 is a hinge, 10 is a stay, 11 is a guide pin, and 12 is a lock. Note that the same reference numerals in the figures indicate the same or corresponding parts.

Claims (1)
