Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a sheet guide structure of a printer for guiding cut sheets and continuous paper.

[Conventional technology]

The sheet guide of the conventional printer is shown in FIGS.
As shown in (c), the sheet guide 31 and the separator 32 have different shapes, and the sheet guide and the separator that can be used in common (c) require an operation to bring them into their respective states. There was a problem due to the noise due to the vibration of the mechanical body from the push-type tractor unit 33 and the paper discharge unit 34 and the noise due to the wire impact of the printing unit.

[Problems to be solved by the invention]

However, in the above-mentioned conventional technology, at least two parts such as a sheet guide for guiding single-cut sheets and a separator for guiding continuous sheets are required, which is accompanied by storage when not in use by a user, operability when mounting, and increase in the number of parts Cost increase is a problem. As for the sheet guide and separator that can be used in common, it is necessary to operate to set each state, and structurally there are problems such as difficulty in simplification due to the restriction of the shape of the mounting part of the housing. It was In addition, the opening shape of the paper insertion and ejection section is not uniform, and noise due to wire impact during printing is radiated from the opening, but it is difficult to always take uniform noise countermeasures. There is a problem that noise is emitted due to the vibration of the mechanical body due to the opening of the housing main body of the push type tractor portion for continuous paper feeding.

Therefore, the present invention solves such a problem, and its purpose is to make the separator for continuous paper and the sheet guide for single-cut paper completely identical to reduce the number of parts, and to store and install it for users. The purpose is to eliminate the troublesomeness and reduce the noise by radiating noise by reducing the number of openings.

[Means for solving problems]

In the printer according to the present invention, the continuous paper inserted from the rear of the printer is sent to the printing unit by the push tractor, and the printed continuous paper is discharged from the upper surface of the printer. A first inclined surface portion (3b) that constitutes a guide surface along the paper guide that guides to the paper guide, and guides the cut paper and the continuous paper after printing, which are inserted into the paper guide.
Is connected to the continuous paper insertion port (5) at the rear of the printer, and the continuous paper discharged along the first slope is inserted into the continuous paper. It is characterized by comprising a sheet guide which has a second inclined surface portion (3a) which guides to the rear of the printer with a gap, and which is arranged so as to cover above the push tractor.

〔Example〕

An example of one embodiment of the present invention is shown in FIG. A print head 2a, a platen 2b, a paper guide 2c are provided inside a housing 1a and a cover 1b which form the printer, and a push-type tractor 2d is provided at the rear thereof.
A mechanical body having is attached. The sheet guide 3 is attached to the housing 1a of this printer. This sheet guide 3
Is the first sheet guide for the cut sheet guide having an angle along the paper guide 2c between the sheet guide 2c and the platen 2b.
Slope 3b and the first slope 3b for guiding the discharged paper to the rear when the continuous paper is used, through the curved portion to the second slope 3b.
Has a slope 3a. Further, the side portion of the sheet guide 3 is covered with a hole to prevent noise emitted from the tractor portion or the like.

For continuous paper, push the tractor 2d from the continuous paper insertion slot 5.
Is set to. Single-cut sheets are for inserting and discharging single-cut sheets 4
The printed and set paper is ejected from the paper ejection port 4 through the ejection path 8 from here. When using continuous paper, the continuous paper set in the push-type tractor 2d is guided by the paper guide 2c to the printing unit 2a, and is discharged from the paper discharge port 4 after printing, and the continuous paper path 2 is moved to the sheet guide second part. It is discharged to the rear along the slope 3a. Further, a sound absorbing material 6 is attached to the inner side surface of the sheet guide 3 to have a sound absorbing effect.

FIG. 2 is a perspective view of the embodiment shown in FIG. 1, and shows a state in which continuous paper is inserted through the insertion port 5 and discharged through the discharge port 4.

[Effect of device]

The sheet guide of the printer according to the present invention has an end portion located at the rear of the continuous paper insertion port (5) at the rear of the printer, and with the continuous paper into which the continuous paper discharged along the first slope portion is inserted. Since there is a second beveled portion (3a) that guides the printer toward the rear of the printer with a space between them, the continuous paper that is about to be inserted and the discharged continuous paper are in contact with each other and both are in close contact with each other due to static electricity or the like. With a simple structure, it is possible to prevent a trouble that the printer is pulled into the printer in this state. Further, since the first slanted portion serves as the guide surface of the cut paper and the guide surface of the continuous paper after printing, and can be a single component, the number of parts is reduced and the operability is improved. Further, since the sheet guide is arranged so as to cover above the push tractor, noise generated from the printer can be effectively blocked.
