Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic device such as a POS terminal, an electronic register, etc. to which an optional unit can be attached.

[0002]

2. Description of the Related Art As an electronic register which is an example of the above electronic equipment, as shown in FIG. 5, an input keyboard 2 is provided at the front of a cabinet 1, and a display 3 and a print unit 4 are provided at the rear thereof. In the standard specification, as shown in FIG. 5, the printer unit 4 is provided with a paper feed mechanism 6 for receiving the receipt paper 5 at the rear thereof.

If necessary, the paper feed mechanism 6 can be replaced with an optional unit 7 using a two-plate pressure sensitive paper as shown in FIG.

In order to mount the optional unit 7, for example, as shown in FIGS. 7 and 8, an opening 9 which can be opened and closed by a cover 8 is provided at the rear of the cabinet 1 composed of upper and lower cabinets 1a and 1b. Inside the opening 9, a screw stopper 10 of the cover 8 and a screw stopper 12 for mounting the lower cabinet 11 of the option unit 7 were provided.

[0005]

However, in the above-mentioned conventional option unit mounting structure, the opening 9 is attached when the cover 8 is attached or detached and the option unit 7 is attached or detached.
It is necessary to disassemble the cabinet 8 in order to expose the inner screw-fastening portions 10 and 12, so that disassembling and assembling is troublesome, and the printer portion 4 is disassembled, which may cause an unnecessary failure. was there.

It is an object of the present invention to easily and easily attach an optional unit without disassembling the cabinet.

[0007]

In order to achieve the above object, the present invention forms an opening provided with a screw fixing portion for attaching an optional unit at an end portion of a cabinet, and has an outer shape along the outer shape of the cabinet. In an electronic device configured to detachably attach the configured cover to a cabinet to close the opening, slide guide means including a guide groove and a ridge is provided at a joint portion between the opening and the cover. And an elastic engaging means that engages with the slide guide means in a direction intersecting with the cover attaching / detaching direction, and a slide corresponding to the slide guide means provided in the opening at the joint portion of the option unit with respect to the opening. The guide means is provided.

[0008]

According to the above construction, for example, as shown in FIG.
Vertical protrusions that form slide guide means are formed on the left and right inner surfaces of the opening 9 formed in the cabinet 1 of the device body, and slides corresponding to the protrusions are formed on the left and right outer surfaces of the cover that closes the opening. The guide groove as the guide means is formed vertically, and the cover is formed by forming concave and convex engaging portions that elastically engage in the inner depth of the opening and the front edge of the cover from the front-rear direction. Can be attached to and detached from the cabinet without tools.

Further, as shown in FIG. 2, by forming guide grooves as slide guide means corresponding to the projections of the opening on the front left and right outer surfaces of the lower cabinet of the optional unit, the lower cabinet is formed. Can be easily positioned, loaded into the opening, and screwed to the screw stopper in the opening.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An optional unit mounting portion of a printer unit 4 of the present invention when applied to the electronic register shown in FIG. 5 is shown in FIGS.

Upper and lower cabinets 1a which can be separated into upper and lower parts,
An opening 9 for attaching the option unit 7 is formed at the rear end of the cabinet 1 made of 1b, opening rearward and upward.

A protrusion 13 (slide guide means) that extends vertically is provided at a position near the rear of the left and right inner surfaces of the opening 9, and a screw stop 12 for attaching an optional unit is provided upright at the inward position. Has been done. Further, a rear wall 14 of the upper cabinet 1a is located in the upper inner part of the opening 9, and an engaging portion 15 having a concave and convex shape is provided at a lower end edge thereof in a rearward direction.

The opening 9 is closed from the rear and the upper side by a cover 8 fitted and attached to the opening 9.

The cover 8 has an outer shape that conforms to the outer shape of the lower cabinet 1b, and has guide grooves 16 (slide guide means) which are fitted and inserted into the protrusions 13 from above on the left and right outer surfaces thereof. At the same time, an engaging portion 17 that engages with the engaging portion 15 from the rear is formed on the front end edge of the cover 8.

Therefore, the cover 8 is positioned forward and backward by the fitting of the protrusion 13 and the guide groove 16, and the vertical movement is prevented by the engagement of the engaging portions 15 and 17 from the front and rear. Is attached to the cabinet 1 to close the opening 9.

2 and 4 show the case where the option unit 7 is attached to the opening 9 from which the cover 8 has been removed.

The lower cabinet 11 of the option unit 7 is set to a size that fits into the opening 9, and hollow rectangular screw mounting seats 18 are provided on the left and right of the front end of the optional unit 7 so as to correspond to the screw stoppers 12. Guide grooves 19 (slide guide means) corresponding to the protrusions 13 of the opening 9 are provided on the left and right outer surfaces of the cabinet 11.
Therefore, the lower cabinet 11 is fitted into the opening 9 from above by the guide of the protrusion 13 and the guide groove 19 so that the screw mounting seat 18 matches the screw fixing portion 12, and these are connected by the screw 20 to lower the lower cabinet 11. The cabinet 11 can be connected to the cabinet 1.

The present invention can be implemented by being modified into the following forms.

(1) The slide guide means on the left and right inner surfaces of the opening 9 is used as a guide groove, and the slide guide means of the cover 8 and the lower cabinet 11 of the option unit are formed as ridges.

(2) The slide guide direction of the slide guide means (guide groove and ridge) is configured in the front-rear direction so that the cover 8 and the lower cabinet 11 of the option unit are fitted into the opening 9 from the rear side, and the front end of the cover 8 is formed. The engaging portions 15 and 17 are configured to elastically engage the lower end of the rear wall 14 of the upper cabinet 1a in the vertical direction.

Although the above embodiments have been described by applying to an electronic cash register, the present invention is not limited to an electronic cash register, and can of course be applied to a bank terminal and other POS terminals.

[0022]

As described above, according to the present invention, the cover can be easily removed without a tool, and the option unit can be easily attached to the opening where the cover is removed without disassembling the cabinet. As a result, it is possible to prevent unnecessary breakdown of the interior mechanism due to disassembly of the cabinet.
