Abstract

PURPOSE:To reduce printing noise by arranging a printing head at a position behind the edge of a paper insertion port which is blocked by paper straddling a platen and a guide, in opposition to the platen. CONSTITUTION:A paper insertion port 1a located above a printing head 2 is covered by paper 4 which straddles a platen 3 and a guide 1a, and the paper 4 shuts off a printing noise generated by printing. As a result, the volume of the printing noise which leaks from the paper insertion port 1a to the outside is reduced and thus the noise can be muffled to a low level. In the meantime, the printing head 2 and ink ribbon are replaced by opening an attachment cover, and a printing position is checked by a checking mirror.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an impact printer.

[Prior Art] As shown in FIG. 2, conventional printers of this type have a built-in platen 3 facing the paper insertion slot 1a opened on the top side of the printer main body 1, A sheet of paper 4 guided along an inclined guide 1b provided on one side of the edge is wound around the circumferential surface of the platen 3. The print head 2 for rough printing is arranged at a position in front of the platen 3,
A maintenance front cover 7 is attached to the printer body 1 above the print head 2.

[Problems to be Solved by the Invention] In the conventional printer described above, the print head 2 is located in front of the platen 3, so the printing sound is caused by the paper insertion [11a
There is a drawback that leakage is likely to occur from the gap between the front cover 7 and the front cover 7, and noise is generated.

An object of the present invention is to provide an impact printer that solves the above problems.

[Means for Solving the Problems] In order to achieve the above object, the impact printer of the present invention includes a guide provided facing the paper insertion slot and provided on one side of the rim of the insertion slot. The paper has a platen around which paper guided along the platen is wrapped, and a print head that prints on the paper wrapped around the platen, and the print head is connected to the platen so that the paper straddles the platen and the guide. It is arranged at the rear position on the edge side of the paper insertion slot which is closed by the paper slot.

[Example] Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a sectional view showing one embodiment of the present invention.

In Figure 1, there is a paper slot 1 on the top of the printer body 1.
A is opened, a platen 3 is built in facing the paper insertion opening 1a, and a guide 1b for roughly guiding the paper 4 is provided adjacent to and inclined toward the platen 3.

The print head 2 for rough printing is disposed at a rear position on the edge side of the paper insertion opening 1a which is closed by the paper 4 that straddles the platen 3 and the guide 1bk. Further, a print position confirmation mirror 6 for checking the print position by the print head 2 at the rear position of the platen 3 through the paper insertion port 1a, and a print head attachment/detachment cover 5 are provided.

In the embodiment, a paper inlet 1a located above the print head 2 is covered with a paper 4 that spans a platen 3 and a guide 1a, and the paper 4 blocks the printing noise generated during printing. , the amount of printing sound leaking to the outside from the paper insertion port 1a is reduced, and noise can be suppressed to a low level. On the other hand, the print head 2 is replaced with an ink ribbon (not shown) by opening the cover 5, and the printing position is checked using the confirmation mirror 6.

``Effects of the Invention'' As explained above, the present invention has the effect of lowering printing noise compared to conventional printers by locating the print head at the rear of the apparatus than the platen.
