Abstract

PURPOSE:To prevent jam generation by providing a cover with an exposed hole for sheet introduction over an entire part opposed to a writing table and a cutter, in freely detachable manner. CONSTITUTION:A recording sheet 6 which is allowed to pass through a printing part 9 in such a state that the sheet is stored in a sheet retaining part 7 is automatically transported and then is allowed to come out of a gap between a cutter 20 and a writing table 10. After that, one of the recording sheets 6a is caused to be wound around a sheet winding shaft 11 without a slack, while the other recording sheet 9b is cut using a cutter 16. The rest of work to do is only to place a cover 5 on a main ECR system 3. Subsequently, when attaching the cover 5, the recording sheet 6 does not become slacked as it is not touched by hand. In addition, the generation of a paper jam is prevented because an exposed hole for sheet introduction 23 is opened at a part opposed to the writing table 10.

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a printer that prints on two sheets of long recording paper.

BACKGROUND ART This type of printer uses an electronic cash register (hereinafter referred to as E) because it is convenient to issue one recording paper as a receipt and save the other recording paper as a journal.
(abbreviated as CR). What is shown in FIGS. 4 and 5 is an example. First, the printer 1 includes a printer mechanism section 4 housed inside an ECR main body 3 placed on a drawer 2, and a cover 5 that is detachable from the ECR main body 3. Note that this cover 5 also constitutes a part of the outer casing of the ECR main body 3.

Here, as the printer mechanism section 4, the ECR main body 3 is provided with a paper holding section 7 that holds two sheets of elongated recording paper 6 wound into a roll. A guide path 8 is formed to guide the pulled out recording paper 6 along a predetermined path. This guide path 8 is provided with a printing section 9 whose exit 9a is directed upward, and a writing table 10 that guides one of the recording sheets 6a that has exited the exit 9a. This writing table 10 is a flat member whose one end is located near the exit 9a of the printing section 9, and whose overall shape is slightly inclined from horizontal. And the writing table 1
A paper winding shaft 11 for winding up one of the face recording papers 6a guided to the ECR body 3 is detachably attached to the ECR main body 3. The paper winding shaft 11 is positioned so that the writing table 0 and one of the recording papers 6a are in close contact with each other over a certain area. Note that the other recording paper 6b that has exited the outlet 9a of the printing section 9 is conveyed upward as it is.
A forest-like recess 12 is formed to face the writing table 10 with a slight gap therebetween. A paper exposure hole 13 is formed in the recessed portion 12 at a portion facing the writing table 10, and an outlet 9 of the printing portion 9 is formed.
A slit-shaped paper insertion hole 14 is formed directly above a. A separator 5 is formed on the edge of the paper insertion hole 14 on the side closer to the writing table 10, and a cutter 16 is attached on the opposite side. Here, this cutter 16 is the separator]
It is positioned so that it is higher than 5.

In such a structure, the recording paper 6 is pulled out from the paper holding section 7, guided along a predetermined guide path 8, and subjected to printing at a printing section 9 along the way. After printing, the recording paper 6 that comes out of the exit 9a of the printing section 9 moves along its path. That is, one recording paper 6a is wound around the paper winding shaft 11 and advances while being in close contact with the writing table 10, while the other recording paper 6b is separated from the other recording paper 6a by the separator 15 and is inserted. Insert through hole 14 and proceed upward. Therefore, the recording paper 6a wound around the paper winding shaft 11 is stored as a journal, and the paper insertion hole 1
The recording paper 6b through which the paper 4 has been inserted is pulled forward by the cashier's hand, cut by the cutter 16, and issued as a receipt. Note that the writing table 1. of the recording paper 6a.
The portion in contact with O is exposed to the outside through the paper exposure hole 13 of the cover 5. Therefore, n8 of this recording paper 6a
Additions or corrections can be made to parts.

On the other hand, the procedure for setting the recording paper 3 in the printer 1 is as follows. First, remove the cover 5 from the ECR main body 3. Then, the recording paper 6 wound into a roll is thrown into the paper holding section 7, and the end thereof is guided to the printer 9 and pulled out from the outlet 9a.

Next, the recording paper 6a that had been wound inside is wound around the paper winding shaft 11 that had been previously removed from the ECR main body 3, and the paper winding shaft 11 is attached to the ECR main body 3 again. At this time, make sure that the recording paper 6a does not sag. Then, without inserting the recording paper 6b wound on the outside into the insertion hole I4, attach the cover 5 to the ECR main body 3,
The extra recording paper 6b is pulled forward and cut by the cutter 16, and the setting of the recording paper 6 here is completed.

Problem to be Solved by the Invention However, when setting the recording paper 6 in the printer 1, it is necessary to hold the recording paper 6b by hand in order to push one of the recording papers 6b through the paper insertion hole 14 of the cover 5. Sometimes the recording paper 6b is pulled. As a result, the recording paper 6a wound around the paper winding shaft 11 becomes slack, and the recording paper 6a becomes wavy between the cover 5 attached to the ECR main body 3 and the writing table ]O, which may cause a jam. It has the disadvantage of being.

In addition, in order to avoid such jams, when attaching the cover 5 to the ECR main body 3, it is necessary to prevent the recording paper 6a wound around the paper winding shaft 11 from slackening. is required. Therefore, there is a drawback that setting the recording paper 6 into the printer 1 is complicated.

Furthermore, since the cutter 16 is attached to the edge of the paper insertion hole 14, there is a drawback that the operation of inserting the recording paper 6b into the paper insertion hole 14 is dangerous.

Means for Solving the Problems The invention as set forth in claim 1 includes: a printing unit that prints on two sheets of long recording paper pulled out from a paper holding unit; A cutter for cutting the recording paper, and a writing table having one end located near the exit of the printing section and closely contacting the other recording paper wound on the paper winding shaft with a certain area, A cover having a paper insertion exposure hole formed in the entire portion facing the writing table and the cutter is detachably provided.

According to a second aspect of the invention, the cutter and writing table of the first aspect of the invention are integrally formed, and are rotatably provided with one end as a fulcrum.

In the invention described in claim 1, the path of the recording paper after printing by the printing section is divided into two directions. One of the recording sheets is wound around a paper winding shaft, and the portion that is in close contact with the writing table is exposed to the outside through the paper exposure hole, and is used for additions or corrections. The other recording paper advances straight as it is and is subjected to cutting by a cutter. On the other hand, when setting recording paper, remove the cover, wrap one recording paper that comes out from between the cutter and writing table through the printing section around the paper winding shaft without any slack, and then set the other recording paper on the cutter. Just cut it out and attach the cover. Therefore, since the cover does not touch the recording paper at times, it does not cause the recording paper to sag. Furthermore, since there is a paper insertion exposure hole in the part facing the writing table, this part jams are prevented from occurring. Furthermore, the cover is easy to attach, and furthermore, since the cutter is not touched when setting the recording paper, operational safety is ensured.

In the invention set forth in claim 2, the cutter and the writing table rotate integrally with respect to the apparatus main body. Therefore, if the recording paper gets stuck between the printing section and the cutter or writing table when setting the recording paper, the recording paper can be easily taken out by rotating the cutter and the writing table.

Embodiment A first embodiment of the present invention will be explained based on FIGS. 1 and 2. Note that the same parts as those shown in FIGS. 4 and 5 are designated by the same reference numerals, and explanations thereof will be omitted (the same applies hereinafter). First, in the printer mechanism section 4, there is a
A cutter 20 is attached. Therefore, a small gap 21 is formed between the cutting edge 20a of the cutter 20 and the end of the writing table 10.
