Abstract

PROBLEM TO BE SOLVED: To prevent an unfavorable carrying of a continuous recording paper from generating by providing a space part in which a folding line of the continuous recording paper can be set aside, at the front end on the internal surface of an upper surface plate which becomes a guiding surface for the carrying of the continuous recording paper. SOLUTION: This recording paper holder 5 comprises a flat box-shaped recording paper housing part 5a which houses a recording paper 4, and a recording paper guiding part 5b which stands upward at the rear end part of the recording paper housing part 5a. A first form 6 of the recording paper 4 being housed in the recording paper housing part 5a, is made to pass a carrying passage 7 of the recording paper guiding part 5b, and is fed to a platen roller 1 from a suction port 8 at the rear upper end of a printer 2. The upper surface plate 12 of the recording paper housing part 5a is formed into a shape wherein the front end part is bent upward to form a space part 13, and a folding line 14 which is the border between a second form 10 and a third form 11 of the recording paper 4, can take shelter. Therefore, the elastic force of the recording paper 4 due to the folding, is not applied to the internal surface 22a.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper holder for a portable terminal having a printer for performing printing by winding a foldable continuous recording paper around a platen roller, and more particularly to a paper holder for storing a foldable continuous recording paper therein. And a paper holder on which a portable terminal is mounted on a top plate to supply continuous recording paper from behind a platen roller.

[0002]

FIG. 3 is a sectional view showing an example of a conventional paper holder.

As shown in FIG. 3, a portable terminal 3 having a printer 2 which accommodates a foldable continuous recording paper (recording paper) 4 therein and wraps the recording paper 4 around a platen roller 1 to perform printing. A conventional paper holder 1 mounted on a face plate 22 to supply recording paper 4 from behind the platen roller 1
5 is a flat box-shaped paper storage unit 15 for storing the recording paper 4
a portable terminal 3 is mounted on the upper surface plate 22 of the paper storage unit 15a, and the portable terminal 3 is mounted on the upper surface plate 22 of the paper storage unit 15a. 3 is fixed in close contact with the paper guide 15b, and the first sheet 6 of the recording paper 4 stored in the paper storage 15a is passed through the transport path 17 of the paper guide 15b, and Suction port 8 at upper rear
To the platen roller 1 to be mounted between the platen roller 1 and the print head 9.

The portable terminal 3 prints on the first sheet 6 by the print head 9 of the printer 2 and conveys the recording paper 4 by rotating the platen roller 1. The succeeding second sheet 10 is conveyed in the direction of arrow A while being in contact with the inner surface 22a of the upper plate 22.

[0005]

In the conventional paper holder 15 as described above, since the inner surface 22a of the upper plate 22 is flat, when the recording paper 4 is conveyed, the second sheets 10 and 3 The fold 14, which is a boundary between the sheet 11 and the sheet 11, comes into strong contact with the inner surface 22a of the upper plate 22 due to the elasticity of the folding of the recording paper 4, and this causes resistance of the transportation of the recording paper 4 to cause transportation failure. There is a problem that there is.

[0006]

A paper holder according to the present invention comprises:
A portable terminal having a printer that accommodates a foldable continuous recording paper inside and has a printer that winds and transports the continuous recording paper around a platen roller on an upper surface plate is mounted, and supplies the continuous recording paper from behind the platen roller. A space portion for retracting a fold of the continuous recording paper is provided at a front end portion of an inner surface of the upper surface plate serving as a guide surface for conveying the continuous recording paper. The length of the portion is a value that can sufficiently reduce the contact resistance of the fold of the continuous recording paper.

[0007]

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a sectional view showing an embodiment of the present invention.
FIG. 2 is an enlarged sectional view of a portion B in the embodiment of FIG.

In FIG. 1, a paper holder 5 holds a recording paper 4
And a sheet guide portion 5 that rises upward at the rear end of the sheet storage portion 5a.
b. The portable terminal 3 mounted on the top plate 12 of the sheet storage portion 5a is the same as the portable terminal shown in FIG. 3, and therefore detailed description of its configuration and operation will be omitted.

The configuration of the paper guide section 5b of the paper holder 5 is the same as the configuration of the paper guide section 15b of FIG. 3, and the first sheet 6 of the recording paper 4 stored in the paper storage section 5a is transferred to the paper guide section. The printer 2 is supplied to the platen roller 1 from a suction port 8 at the rear upper end of the printer 2 after passing through a transport path 7b.

As shown in FIG. 2, the upper surface plate 12 of the sheet storage section 5a has a front end portion bent upward to form a space portion 13, and the second sheet of the recording paper 4 is formed. The fold 14, which is the boundary between the 10 and the third form 11, can be retracted. In the paper holder 5 configured as described above, when the recording paper 4 printed on the first sheet 6 by the print head 9 of the printer 2 of the portable terminal 3 is conveyed by the platen roller 1, the recording paper 4 is The second sheet 10 is conveyed in the direction of arrow A while being in contact with the inner surface 12a of the upper surface plate 12, but at this time the fold line 14 is retracted into the space portion 13 so that the inner surface 2 of the upper surface plate 22 is retracted.
No contact is made with the inner surface 22a, so that the elasticity due to folding of the recording paper 4 does not act on the inner surface 22a. For this reason, the conveyance resistance of the recording paper 4 is reduced, and it is possible to prevent occurrence of conveyance failure.

When the recording paper 4 is conveyed to some extent and an appropriate length of the third sheet 11 can come into contact with the top plate 12, the elasticity of the fold 14 becomes small. However, since the conveyance resistance is small, no conveyance failure occurs. The length of the space 13 is set to such a value that the contact resistance of the fold 14 can be sufficiently reduced.

[0013]

As described above, in the paper holder of the present invention, continuous recording is performed by bending the front end of the upper surface plate of the paper storage portion upward to form a space for retracting the fold of the continuous recording paper. There is an effect that it is possible to reduce the conveyance resistance generated by the fold of the paper contacting the inner surface of the upper plate, and thus it is possible to prevent the occurrence of a conveyance failure of the continuous recording paper.
