Description

[Detailed Description of the Invention] This invention relates to a label issuing device that has an improved main body case composed of a metal mounting frame and a vacuum-formed thermoplastic cover.

FIG. 1 shows a label issuing device, and 1 is a main body case that houses a printer.

A display 2, a keyboard section 3, and a label issuing section 4 are attached to the upper front half of the main body case 1.

Reference numeral 5 denotes a weighing section, and a receiver sends a weight signal corresponding to the weight of the article placed on the plate to the printer control circuit in the main body case 1.

The printer is then driven based on this control circuit to perform predetermined printing on the label.

By the way, if the main body case 1 is manufactured from the same material, it will be expensive, so the flat mounting frame 6 on which the label issuing unit 4 etc. are mounted is molded from a metal material, and the other parts (cover) 7 are made of a metal material. The frame 6 and the cover 7 are formed by vacuum forming thermoplastic plastic.

However, in the case of the conventional printer, during use, the case 1 is heated due to heat generated by each drive unit, printer control mechanism, etc. of the printer housed in the case 1.
When the temperature reaches above ', the cover 7 has a higher coefficient of thermal expansion than the frame 6, so the cover 7 is fixed to the thermoformed waist frame 6 with screws 8... as shown in Figs. 2 and 3. The part other than the part that is attached is separated from the frame 6,
There was a problem in that the waveform warped and the appearance of the device deteriorated.

This idea was made based on the above circumstances, and its purpose was to reduce production costs.
Another object of the present invention is to provide a label issuing device that can prevent deterioration in appearance due to thermal deformation.

That is, in this invention, as shown as an embodiment in FIGS. 4 to 6, a main body case 11 that houses the printer has a flat metal mounting frame 12 and a thermoplastic cover 13 formed by vacuum forming. It consists of
In a label issuing device in which a label issuing unit is attached to the mounting frame 12, the upper edge 14 and both side edges 15, 15 of the mounting frame 12 are bent inward, and the frame 12 is attached to the cover 13. When the cover upper part 16 is located inside the corner portions 16a, 16
a to the upper edge sides 14a, 14a of the frame 12, and lower end portions 17a, 17a of the cover side parts 17.17 to the lower ends 15 of the frame 12, respectively.
a, 15a with screws 18..., and
A covering member 20 is attached to the protruding edge 19 of the cover 13 to cover the gap created between the frame 12 and the cover 13.

That is, even if a gap occurs between the frame 12 and the cover 13, if the gap is caused by thermal deformation of the cover 13, it will be in the shadow of the covering member 20 and will not be visible from the outside. It is something.

Note that the lower part of the case 11 is attached to a bottom plate (not shown).

Further, the covering member 20 is made of plastic and has a U-shaped cross section.

Therefore, in the label issuing device having the above configuration, since the frame 12 is located inside the cover 11, objects can be prevented from hitting the frame 12, and the number of fixing points between the frame 12 and the cover 11 can be reduced. Therefore, the portion 16a near the corner of the upper cover 18,
16a and both upper edge portions 14a, 14 of the frame 12.
a and each lower end portion 17 of the cover both sides 17.17
a, 17a and the lower ends 15a, 15 of both side edges of the frame 12
It is possible to have a configuration in which only the four locations a are fixed.

Furthermore, since the frame 12 and the cover 13 are fixed at the four locations mentioned above, even if the cover 13 is thermally deformed, the warpage at the intermediate portion between the fixed parts will be relatively smooth, and the appearance of the device will be extremely improved. It won't make things worse.

Moreover, since the covering member 20 is attached to the protruding edge 19 of the cover 13, the gap created between the fixing parts of the cover 13 and the frame 12 due to thermal deformation of the cover 13 is covered by the covering member 20. 20, and in this respect, the appearance of the device can also be maintained in a good condition.

As explained above with reference to the embodiments, in the label issuing device of this invention, the main body case is composed of a metal mounting frame and a thermoplastic cover, so that manufacturing costs can be reduced. In addition, it is possible to prevent the appearance from deteriorating due to thermal deformation.
