Abstract

PROBLEM TO BE SOLVED: To provide a paper feeder for feeding a cut paper as well as a roll paper by using a holder. SOLUTION: A holder 6 is fitted to the tip of a roll paper 1 supported by a support mechanism 2 and also the curl of the tip is corrected and set to a tray 3 and the paper feeding from the tray 3 to a printer 7 is started by the print operation of an operator and the rotation of a pick up roller 4 is started by a control means 5 and the roller paper 1 set to the tray 3 is introduced to the printer 7 and at the same time, the roll paper 1 is led upto a carriage 71 by a main roller 72 started its rotation. Therefore, when the roll paper 1 is fed as being held to the holder 3, a paper feed amount with a longer size than the vertical width of the holder 6 is fed out after controlling the main roller 72 and a printing is carried out after taking out the holder 6 from the roll paper 1.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a paper feeder,
In particular, the present invention relates to a paper feeder that feeds roll paper from a tray similar to cut paper.

[0002]

2. Description of the Related Art In a conventional paper feeder, after a roll paper is returned into a support mechanism, a cut paper inserted into a manual feed unit is fed, and the roll paper and the cut paper are fed by a single paper feeder. Alternatively, or cut paper from the tray,
As shown in FIG. 2, a roll 3 feeds the roll paper from a manual path provided separately, and a tray 3 for setting the cut paper, and a pickup roller 4 for sending out the cut paper set on the tray 3. A main roller 72 for feeding the cut sheet sent from the pickup roller 4 and a carriage 7 having a printing means for printing on the cut sheet.
The printer unit 107 includes a printer unit 107, a roll paper 1, a support mechanism 2 that supports the roll paper 1, a pickup roller 4, a main roller 72, and a control unit 5 that controls the carriage 71.

When printing a cut sheet, the cut sheet is set on the tray 3 and printing is performed according to an operator's instruction. When the control means 5 rotates the pickup roller 4 and the main roller 72, the cut sheet is moved from the tray 3. The cut sheet is sent to the carriage 71 and printing is started. On the other hand, in the case of printing on the roll sheet 1, the roll sheet 1 is manually inserted into the carriage 71 and printing is started by an instruction of the operator.

[0004]

However, a conventional paper feeder which does not have a manual paper feed path cannot feed roll paper from a tray like a cut sheet or a postcard. There was a problem that a paper guide mechanism had to be provided.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a paper feeding device capable of feeding roll paper from a tray in the same manner as feeding cut paper.

[0006]

In order to solve the above-mentioned problems, a paper feeder according to the present invention comprises a sheet formed of roll paper / cut paper, a tray for setting the paper, and When the roll paper is set, a holder having one or two sides adhered / welded to the leading end of the roll paper, a pickup roller for feeding the roll paper or cut paper set on the tray, and a pickup roller And control means for controlling the pickup roller so that the holder sandwiched between the leading ends of the roll paper is sent out only when the roll paper is sent out.

[0007]

Next, a sheet feeding device according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a configuration diagram (A) of a sheet feeding device according to an embodiment of the present invention, and a sectional view (B) when roll paper is set in a holder.

A sheet feeding device according to an embodiment of the present invention comprises:
As shown in FIG. 1, a support mechanism 2, a roll paper 1 supported by the support mechanism 2, and a holder 6 having one or two sides bonded / welded to the leading end of the roll paper 1
And a tray 3 for setting the roll paper 1 or cut paper having the holder 6 sandwiched at the leading end thereof;
, A pickup roller 4 for feeding the roll paper 1 or cut paper, a main roller 72 for feeding the roll paper 1 or cut paper sent from the pickup roller 4, and printing for printing on the roll paper 1 or cut paper. A printer unit 7 having a carriage 71 on which means is mounted, and a control for controlling the pickup roller 4 so that when the roll paper 1 is sent out by the pickup roller 4, the holder 6 sandwiched between the leading ends of the roll paper 1 is sent out. And means 5.

Further, the holder 6 of the paper feeder according to the embodiment of the present invention is made of a material such as polyester, vinyl chloride or paper and has a thickness of about 100 μm and a vertical width approximately equal to the vertical width of the tray 3. Are two sheets having the same length and width as the width of the roll paper 1 bonded or welded on one or two sides.

Next, the operation of the paper feeder according to one embodiment of the present invention will be described with reference to the drawings.

As shown in FIG. 1B, the operation of the paper feeder according to the embodiment of the present invention is as follows. The holder 6 is sandwiched between the leading end of the roll paper 1 supported by the support mechanism 2 and the leading end curl is performed. Is set on the tray 3, and as shown in FIG. 1A, the feeding operation from the tray 3 to the printer unit 7 starts a printing operation by the operator, and the control unit 5
Then, the pickup roller 4 starts rotating, and the roll paper 1 set on the tray 3 is guided to the printer unit 7. At the same time, the roll paper 1 is guided to the carriage 71 by the main roller 72 which is starting to rotate.

Accordingly, when the roll paper 1 is fed while being sandwiched by the holder 3, the main roller 72 is operated by the operator performing the same operation as printing of cut paper or the like.
Is controlled, the paper feed amount corresponding to the dimension longer than the vertical width of the holder 6 is sent out, and after the holder 6 is removed from the roll paper 1, printing on the roll paper 1 is started by an operator's operation.

[0014]

As described above, according to the paper feeding apparatus of the present invention, in a horizontal printer apparatus having no manual paper feeding path, roll paper is supplied from a tray in the same manner as cut paper and postcards. Paper can be fed, paper can be fed regardless of the degree of roughness of the cut state of the roll paper tip, and a roll paper feed guide mechanism is not required.
