Abstract

PURPOSE:To reduce noise while enhancing printing quality by reducing the vibration of printing paper, by forming a printing stand into a cylindrical form having a hollow part and providing a large number of fine suction apertures to the surface thereof and further providing a suction means in a state communicated with the hollow part of the printing stand. CONSTITUTION:A printing stand 1 is positioned in opposed relation to a printing head 3 and performs the function for pressing printing paper from the back side thereof when a printing head 3 applies printing on the printing paper 5 through an ink ribbon 4 within the movable range of the printing head 3. A large number of fine suction apertures 6 are provided to the contact surface with the printing paper 5 of the printed stand 1 and air is sucked into the printing stand 1 through the suction apertures 6 by the suction means 2 connected to the hollow part of the printing stand 1. By this method, the printing paper 5 is sucked to the printing stand 1. At the time of printing, the printing paper 5 is vibrated by the impact of the printing, the printing paper 5 is vibrated by the impact of the printing head 3 but the vibration of a printing paper 5 is weakened by proper sucking from the printing stand 1.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a printing stand for a serial printer.

[Conventional technology]

Conventional serial printers have a structure in which a print head and a print stand sandwich print paper and an ink ribbon.

[Problems to be solved]

However, with the conventional configuration, there was a problem in that during printing, the printing paper moved in the gap between the print head and the printing stand, generating noise and deteriorating print quality.

Solution to Problem c] The present aAFi solves the above problems, and is a serial printer in which the print head is pressed against the printing stand via an ink ribbon and printing paper to perform predetermined printing on the printing paper. The printing stand is formed into a cylindrical shape having a hollow part, and a large number of fine suction holes are provided on the surface thereof, and a suction means communicating with the hollow part of the printing stand is attached.

[Effect]

The present invention uses a suction means to suck the hollow part of the knot-shaped printing stand, and sucks air toward the inside of the printing stand through a large number of fine suction holes on the surface of the printing stand, thereby moving the printing paper onto the printing stand. The suction reduces the vibration of the printing paper, reduces noise, and improves printing quality.

〔Example〕

Next, an example thereof will be described with reference to FIGS. 1 and 2.

FIG. 1 is a perspective view of a serial printer to which an embodiment of the print stand for a serial printer according to the BAVc of the present invention is applied, and FIG. 2 is a perspective view of a 7-real printer to which another embodiment of the above-mentioned print stand is applied.

In FIG. 1, the printing stand 1 is located in a position facing the printing head 3, and when the printing head 3 prints on the printing paper 5 via the ink ribbon 4 within the movable range of the printing head 3, the printing bed 1 is positioned opposite to the printing head 3. It plays the role of pressing from the back side. That is, printing stand 1
A large number of fine suction holes 6 are provided in the contact surface with the upper printing paper 5, and air is sucked into the printing table 1 through the suction holes 6 by the suction means 2 connected to the hollow part of the printing table 1. It is sucked inward. As a result, the printing paper 5 is attracted to the printing table l. 7 is a guide cx that guides the printing paper.
-9.

When the print head 3 prints on the print paper 5, the print paper 5
vibrates due to the impact from the print head 3, but the movement of the print paper 5 is weakened by moderate suction from the print table 1.

Next, FIG. 2 shows another embodiment of the printing stand. This printing stand 8 is a combination of the printing stand 1 and the guide roller 7 shown in FIG. 1. Therefore, the print head 3
When printing on the printing paper 5, the printing paper 5 is attracted by the printing table 8, its vibrations are weakened, and it is properly guided. In this way, by providing the printing table 1 or 8 with the function of sucking the printing paper 5, vibrations can be reduced and high quality printing can be achieved.

〔effect〕

As explained above, since the present invention is provided with means for suctioning the print paper on the printing table, this suction can reduce the amount of photographing of the print paper, reduce noise, and improve print quality. .
