Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printing device.

[0002]

2. Description of the Related Art FIG. 3 and FIG. 4 show a schematic structure of a conventional printer. In these figures, 1 is a main body case,
The printing unit 2 and the writing table 5 are provided in the main body case 1.
The paper take-up reel 11 and the like are housed.

The printing section 2 is composed of a platen 3 and a print head 4. The roll paper P is supplied to the printing unit 2 through the paper insertion port 9.

The paper take-up reel 11 is means for winding the roll paper P printed by the printing section 2, and is detachably supported by the support frames 15, 15. As shown in FIG. 4, the paper take-up reel 11 has a take-up core portion 13 having a length corresponding to the width of the roll paper P, and flange portions 12 attached to both ends of the take-up core portion 13. 12 and end shafts 14, 14 projecting outward from the flanges 12, 12. The upper ends of the support frames 15 and 15 receive U for receiving the end shafts 14 and 14 of the paper take-up reel 11.
Character-shaped notches 15a, 15a are formed.

Further, the writing table 5 serves as a base for manually correcting erroneous printing and the like, and is arranged between the printing section 2 and the paper take-up reel 11. The writing table 5 is rotatably supported by the main body case 1 via a support shaft 6, and is held by a stopper 7 at a position shown by a solid line in FIG. In FIG. 4, 5a
Is a mounting hole for mounting the writing table 5 to the support shaft 6.

[0006]

By the way, in the above-mentioned conventional printing apparatus, miniaturization is required in order to expand the field of use. In order to respond to such requests,
Large paper take-up reel 11 among the components of the printer
It is conceivable to reduce the accommodation space of. But,
This makes it difficult to remove the paper take-up reel 11 and makes it difficult to handle.

In view of the above circumstances, it is an object of the present invention to provide a printing apparatus which can be miniaturized and improved in handleability.

[0008]

A printer according to the present invention is a printer provided with a writing table between a printing section housed in a main body case and a paper take-up reel. A pair of L-shaped holding members, each of which is rotatably supported at an interval larger than the length of the paper take-up reel, are provided, and the writing table is provided on each short side of both holding members. A bearing portion for rotatably and detachably carrying each end shaft of the paper take-up reel is provided on the long side.

[0009]

In the present invention having the above structure, the paper take-up reel can be taken out of the main body case by rotating the respective L-shaped holding members with the writing table by hand. As a result, the paper take-up reel can be easily removed.

As described above, since the paper take-up reel can be taken out of the main body case by using the L-shaped holding member,
It is not necessary to separately provide a space for removing the paper take-up reel in the main body case, and the accommodation space can be reduced accordingly.

Therefore, it is possible to achieve improvement in handleability while achieving miniaturization.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 1 and 2, the printing apparatus according to the present embodiment includes a main body case 1, a printing unit 2, a writing table 5, a paper take-up reel 11, and a pair of L-shaped holding members that are characteristic parts of the present apparatus. It is configured to include 21, 21. The same components as those shown in FIGS. 3 and 4 are designated by the same reference numerals, and the description thereof will be omitted or simplified.

Here, the L-shaped holding members 21 and 21 are
The length of the paper take-up reel 11 (both collars 1
2 and 12) are spaced apart from each other and are rotatably supported, and the writing table 5 is provided on each short side 22 thereof and each long side 23 thereof.
Further, bearing portions 24, 24 for rotatably and detachably holding each end shaft 14 of the paper take-up reel 11 are provided.

In this embodiment, in order to increase the structural strength and improve the manufacturability, the L-shaped holding member 21,
21 and the writing table 5 are integrally molded.
Further, each L-shaped holding member 21 is formed so that the opening of the U-shaped bearing portion 24 is held upward at the position shown by the solid line in FIG. 1 during printing. In FIG. 1, 27 is a stopper for holding each L-shaped holding member 21 at the position shown by the solid line in FIG. Further, in FIG. 2, 16 and 16 are mounting holes for mounting both holding members 21 and 21.

Next, the operation will be described. When the L-shaped holding members 21 and 21 are rotated to the position shown by the chain double-dashed line in FIG. 1 with the writing table 5 by hand, the paper take-up reel 11 is taken out above the main body case 1. As a result, the paper take-up reel 11 can be easily taken out.

Thus, the L-shaped holding members 21 and 21
Since the paper take-up reel 11 can be taken out of the main body case 1 by using the
There is no need to provide a special space for removing 1 by hand, and the accommodation space can be reduced accordingly.

According to this embodiment, however, a pair of L-shaped holding members 21, which are rotatably supported in the main body case 1 with a space larger than the length of the paper take-up reel 11 and each of which is rotatable. 21 is provided, the writing table 5 is provided on each short side 22 of both holding members 21 and 21, and each end shaft 14 of the paper take-up reel 11 is rotatably and detachably carried on each long side 23. Since the bearings 24, 24 are provided, the paper take-up reel 11 can be taken out of the main body case 1 by rotating both holding members 21, 21 using the writing table 5. As a result, the paper take-up reel 1 is provided in the main body case 1.
It is not necessary to provide a special space for removing 1 by hand, and the accommodation space can be reduced accordingly.

Further, since the L-shaped holding members 21 and 21 and the writing table 5 are integrally formed, it is possible to increase the structural strength and improve the manufacturability.

Further, since the bearing portion 24 of each holding member 21 is formed in a U shape so that the opening faces upward during printing, the paper take-up reel 11 is securely and rotationally resistant while maintaining the ease of attachment and detachment. Paper roll P
Can be wound up smoothly.

[0020]

According to the present invention, a pair of L-shaped holding members that are rotatably supported in the main body case are provided at intervals larger than the length of the paper take-up reel and are rotatable.
Since the writing table is provided on each short side of both holding members and the bearing portion for rotatably supporting each end shaft of the paper take-up reel is provided on each long side, the writing table can be held by hand. By rotating both holding members, the paper take-up reel can be taken out from the main body case. As a result, it is not necessary to separately provide a space for removing the paper take-up reel in the main body case, and the accommodation space can be reduced accordingly.
