Description

[Detailed Description of the Invention] The present invention relates to a writing table □ for guiding the recording paper of a printer after printing and for writing additions, corrections, etc. by hand.

The purpose of this invention is to make the writing table movable in a compact space, open the entrance part of the paper guide widely when inserting the supply roll paper, make it easier to see, and improve the ease of inserting the supply roll paper. There is a particular thing.

Another object of the present invention is to improve operability when replacing roll paper by automatically opening and closing the writing table depending on the presence or absence of roll paper.

Still another object of the present invention is to provide a writing stand for a printer that is simple in structure, has an extremely small number of parts, is inexpensive, and is compact.

In conventional writing stands, the writing stand makes it difficult to see the entrance of the paper guide, making it difficult to insert call paper.

In addition, the size of the writing stand was small and it was difficult to write.

The present invention eliminates these drawbacks, and one embodiment will be described in detail with reference to FIGS. 1 and 2.

FIG. 1 is a side view of the casing showing a state in which the roll paper is not wound up.

The supply roll paper 1 is a roll-shaped paper on which characters, symbols, etc. are printed.

The paper guide 2 is fixed to the printer in order to guide the supply roll paper 1.

The paper guide 3 is also for guiding the supply roll paper 1, and guides the supply roll paper 1 so that it is fed by the paper feed roller 4.

The paper feed roller 4 is connected to a drive device of the printer and is rotatable.

The paper press roller 5 is engaged with the paper feed roller 4 and always presses down the paper feed roller 4, so that it can rotate following the rotation of the paper feed roller 4.

The guide plate 6 is for guiding the supply roll paper 1 sent out by the paper feed roller 4 and the paper presser roller 5, so as to pass between the platen 7 and the head 8.

The platen 7 serves as a pedestal for the supplied roll paper 1 when printing is performed on the supplied roll paper 1 by the head 8 .

The head 8 prints desired characters, symbols, etc. on the supplied roll paper 1.

The writing table 9 can rotate in the directions of arrows A and B using a support shaft 10 as a fulcrum, and in FIG.
2, the second
It is positioned at the position of

In this state, the gap C between the writing table 9 and the paper guides 2 and 3 appears wide, so it is easy to insert the roll paper 1, and it is easy to use in a compact space compared to conventional ones. can be improved.

FIG. 2 is a side view of the roll paper 1 being wound around the winding shaft 13.

The winding force of the winding shaft 13 is made stronger than the spring force of the spring member 11, and when the roll paper is set, the tension of the roll paper between the paper feed roller and the winding shaft resists the urging force of the spring member. The writing table 9 automatically rotates in the direction of the arrow A about the support shaft 10, and is positioned by the perpendicular pin 12 at a first position approaching the recording paper insertion slot of the printer.

When the supply roll paper 1 is to be replaced again, the take-up shaft 13 is removed and the paper guide section returns to its wide waiting state.

According to the above-mentioned invention, by making the writing table more compact than conventional writing tables and having a sufficiently large space, it is possible to correct the contents printed on journal paper by cashiers at supermarkets, etc. Very easy to write when adding.

Moreover, it solves the problem of the entrance part of the paper guide being difficult to see, and since the writing table opens and closes automatically depending on the presence or absence of roll paper, it is easy to insert roll paper and the replacement of roll paper is quick. It has the characteristics that it can be done reliably in a short period of time, and is widely applicable.

Claims (1)

[Scope of utility model registration request] A printing means for printing characters, symbols, etc. on the paper and a writing table for writing on the paper by hand are provided between a pair of feed rollers that sandwich the paper and a winding member that winds up the paper. In the arranged printer, a fulcrum shaft rotatably supports between a first position approaching the paper insertion opening of the printer such as the writing stand and a second position moving away from the printer;
and a spring member that biases the writing table in the direction of the second position, and during normal printing, the feeding roller and the winding member 1. A writing stand for a printer, characterized in that the writing stand is held in the first position by tension of the sheet of paper against the biasing force of the spring member to enable writing.
