Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printer device having a print part cover panel which covers a print part of the printer device and is provided with a guide part for discharging recording paper.

[0002]

2. Description of the Related Art In recent years, a printer used as an output device such as an information processing device can usually be opened and closed above a printing portion in order to replace an ink ribbon or take a measure when a recording paper is jammed. It has a panel.

A conventional printer device having such a printing section cover panel will be described below with reference to the drawings. FIG. 3 shows a cross section of a conventional printer device. In FIG. 3, reference numeral 12 is a printer unit having a printing unit for printing on the recording paper 13, and reference numeral 20 is a printing unit cover panel which is attached to the printer device so as to be openable and closable and covers the printing unit. As shown in FIG. 4, the printing portion cover panel 20 has a plurality of recording paper guide ribs 21 on the back surface thereof at intervals, and the end surface thereof serves as a recording paper guide surface 22. The guide surface 22 serves as a paper guide when ejecting the recording paper.

The operation of the printer configured as above will be described below. In FIG. 3, after the recording paper 13 is inserted from the lower side and printed by the printing unit of the printer unit 12, the leading end of the recording paper 13 comes into contact with the guide surface 22 of the printing unit cover panel, and along the guide surface 22. It is guided toward the opening and discharged.

As the structure of the paper guide portion of the printing unit cover panel, there are structures shown in FIGS. 5 and 6 in addition to the structure shown in FIG. In FIG. 5, reference numeral 30 is a printing portion cover panel, 31 is a guide surface, and a concave portion 32 is provided on the outer surface of the upper surface.
Have. Further, in FIG. 6, reference numeral 40 is a printing portion cover panel, 42 is a guide surface, and 41 is an undercut portion formed by a mold. All of these structures are intended to achieve both the purpose of smoothly guiding the leading edge of the recording paper and the prevention of uneven thickness during resin molding.

[0006]

However, in the above-mentioned conventional printer device, in the printing portion cover panel having the structure shown in FIG. 4, since there are a plurality of recording paper guide ribs 21, it is difficult to align the molds. There was a problem such as a paper jam near the die matching section 23. Further, in the structure shown in FIG. 5, there is a recess 32 in the outer appearance of the upper surface of the printing section cover panel 30, which causes a problem of not only impairing the appearance but also accumulating dust. Further, in the structure shown in FIG. 6, since the undercut portion 41 is formed, a large inclined pin is required due to the mold structure, which is complicated.

The present invention solves the above-mentioned conventional problems, maintains the paper discharge accuracy, does not impair the appearance, and
The purpose is to simplify the mold structure.

[0008]

In order to achieve this object, a printer device of the present invention is provided with a printing section for feeding and discharging a recording sheet for printing, and an openable and closable mount for covering the printing section. A plurality of hollow portions are formed in the appearance surface that is visually recognized when closed, the guide surface that guides the leading edge of the recording paper when the recording paper is discharged, and the uneven thickness portion that is sandwiched between the appearance surface and the guide surface. It is provided with a panel for a printing part cover which is individually provided and integrally molded.

[0009]

With this structure, the smoothness of the guide surface at the time of discharging the recording paper is maintained, the appearance of the panel for the printing section cover is not impaired, and the mold structure is simple and the shape is excellent in strength. Has become.

1 is a perspective view of a printing unit cover panel of a printer apparatus according to an embodiment of the present invention, and FIG. 2 is a sectional view of the printer apparatus. In FIG. 1 and FIG. 2, reference numeral 10 denotes an integrally molded panel for a printing unit cover, which has an outer surface 11 having no unevenness, and the recording paper 13 printed at the printing unit of the printer unit 12 when the recording paper 13 is discharged. It has a smooth guide surface 14 with no unevenness for guiding. In addition, appearance 1
1. A plurality of hollow portions 18 are formed in the uneven thickness portion 17 sandwiched between the guide surfaces 14. A gas injection hole 1 for supplying gas during molding in order to form this hollow portion 18.
A plurality of 9 are provided on the surface 16. The gas injection hole 19
May be provided on another surface. However, when it is provided on the guide surface 14, since it guides the recording paper 13, it must be made so as not to be convex with respect to the guide surface 14.

Since the operation of the printer of the present invention is the same as that of the conventional example, the description thereof will be omitted.

As described above, in this embodiment, the outer surface, the guide surface for guiding the leading edge of the recording paper when the recording paper is ejected, and the uneven thickness portion formed between the outer surface and the guide surface are hollow. By providing the print section cover panel integrally provided with a plurality of sections, the print section cover panel can be formed into a simple shape without damaging the guide surface and the appearance surface.

[0013]

As described above, according to the present invention, the printing section cover panel can guide the recording paper with a smooth surface without unevenness, and the discharge of the recording paper can be stabilized while the external appearance is uneven. It is possible to create a shape that does not have dust, and there is no accumulation of dust. In addition, the provision of the hollow portion increases the strength of the printing portion cover panel. Furthermore, the mold structure can be simplified.
