Abstract

PURPOSE:To easily feed paper without damaging soundproof effect by forming a guide member guiding the paper supplied from an opening part to the gap between a soundproof wall and a paper stand to a soundproof cover. CONSTITUTION:A paper stand 4 has the rib 4b crossing a paper feed route and the chevron-shape rib 4b having an apex at the end part of the rib 4a and extending to the upper and lower ends thereof formed to the surface opposed to a paper stand 3 thereof. A gap capable of permitting paper to pass is formed between the rib 4a and the opposed part of the rib 4a of the paper stand. In the printer thus constituted, since sound is isolated by the size of the end part of the rib 4a and that of the rib 4a of the paper stand, soundproof effect is not lowered even when a paper supply and discharge port 4c is widened.

Description

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

Conventional technology A conventional printer will be explained below.

FIG. 3 is a cross-sectional view of a future technology printer.

In FIG. 4, 21 indicates a print head 22 or a platen 23.
24 is a front cover that is removably attached to the top of the printing gutter of the housing, and 25 is set in a horizontal position when using continuous sheets, and against a horizontal surface when using single sheets. A paper stand that locks in a position rotated by a certain angle e, 26 has an opening 26 at the upper end for feeding paper.
This is a soundproof cover having a.

SUMMARY OF THE INVENTION However, in the above-mentioned conventional configuration, if the gap between the upper end of the soundproof cover and the facing portion of the paper stand is narrowed to improve the soundproofing effect, it becomes difficult to feed paper.

Means for Solving the Problems In order to solve the above-mentioned conventional problems, the present invention has an opening through which paper is fed, and guides the paper fed from the opening to the gap between the paper stand and the soundproof wall. The guide member was formed into a soundproof cover.

According to the present invention, with the above-described configuration, paper can be fed smoothly even if the gap between the soundproof wall and the paper stand is narrowed.

Embodiment FIGS. 1(a) and 1(b) are cross-sectional views of the paper feeding and discharging section of a printer according to an embodiment of the present invention when a single sheet is used and when a continuous sheet is used, respectively, and FIG. 2 is a section of the same printer. FIG.

In FIG. 1, 1 is a casing, 2 is a front cover, and 3 is a paper stand, which are the same as the conventional technology, so their explanation will be omitted. The paper stand 4 is formed with a rib 4a that crosses the paper conveyance path and a mountain-shaped rib 4b that extends to the upper and lower ends, with the end of the rib 4a being the apex, on the surface facing the paper stand 3. Further, there is a gap 4d between the rib 4a and the opposite portion of the paper stand to allow paper to pass through.

In a printer configured as follows, depending on the size of the end of the rib 4a and the rib 4a of the paper stand 4,
Even if the paper feed/discharge port 4c is widened, the soundproofing effect does not deteriorate. In addition, when paper is fed from the paper feed/discharge port 4C, the rib 4b
Therefore, even if the gap 4b is formed narrowly, the paper can be fed and discharged smoothly.

Effects of the Invention The present invention has an opening through which paper is supplied, and a guide member for guiding the paper supplied from the opening to the gap between the soundproof wall and the paper stand is formed in the soundproof cover. Even if the gap between the paper sheet and the opposing portion is narrow, the paper can be fed smoothly, and paper feeding can be facilitated without impairing the soundproofing effect.
