Description

[Detailed explanation of the invention] [Summary] The printer's pre-print paper, print paper outlet, and post-print paper winding area are all covered by a cover, and the inner wall of the cover is provided with soundproof ribs and drip-proof ribs. By making the cover removable or openable, the printing noise of the printer is reduced and the drip-proofness of the printing paper is improved.

[Industrial application field]

This invention is a hand-held terminal (Hand
Regarding the printer printing paper section of Held Terminal-HHT).

[Conventional technology]

FIG. 4 is a sectional view of a conventional printer. In the figure, 31 is the printer, 32 is paper before printing, 33 is a print paper outlet, and 34 is paper after printing.

Conventional HHT printers generally did not have a soundproof or drip-proof structure. For example, as shown in FIG. 4, a printer head (not shown) of a printer 31 prints on a paper 32 before printing, such as a roll paper, and then outputs the paper 34 after printing as is from a paper outlet 33.

[Problem that the invention attempts to solve]

In this way, conventional HHT printers are soundproof and
Since a drip-proof structure was not provided and the printing paper outlet 33 was exposed, the noise generated when the printer head of the printer 31 struck the paper to print was a problem.

Further, since the printed paper 34 exits from the print paper outlet 33 in an exposed state as shown in FIG. 4, there are problems such as ink smearing or paper tearing when wet with water or the like. Particularly in compact printers, which are convenient in size, paper often gets wet due to rain.

In addition, Utility Model Application Publication No. 60-69660 devises a cover that winds up the paper after printing, but it is not sufficiently soundproof or drip-proof.

In order to solve the above-mentioned problems, the present invention aims to provide a soundproof and drip-proof structure that reduces the printing sound of a printer and improves the drip-proof property of printing paper.

[Means for solving problems]

The purpose of the above is to provide a cover that can be attached to the printer and covers the printer's unprinted paper, the printing paper outlet that prints and outputs the paper, and the winding part that stores the printed paper, and the inner wall of the cover has irregularities. A plurality of soundproofing ribs with a soundproofing rib are placed along the moving direction of the printing paper within the width of the paper after printing, and soundproofing ribs are sandwiched on both sides where the paper passes after printing to prevent unevenness deeper than the unevenness of the soundproofing ribs. This is achieved by providing a printer printing paper section of a hand-held terminal, characterized in that drip ribs are provided respectively along the direction of paper movement after printing, and the cover is openable and closable by means of a hinge. Ru.

[Effect]

The soundproof and drip-proof structure of the HHT printer of the present invention is as shown in FIG. By covering 15 and 15 together with cover 16,
Since it covers all parts of the printer 11 where printing noise is generated and parts connected thereto, it has a soundproofing effect, and also has a drip-proofing effect on the paper 12 before printing and the paper 14 after printing.

Furthermore, by providing the inner wall of the cover 16 with soundproof ribs 17 and drip-proof ribs 18, it is possible to reduce the vibration of the paper due to printing, that is, to reduce the generation of printing noise, and to reduce the paper feeding friction of the paper after printing. At the same time, the drip-proof effect can be enhanced.

By making the cover 16 openable and closable or detachable, the unprinted paper 12 and the printed paper 14 inside the cover 16 can be easily taken out and replaced.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

Figure 1 is a sectional view of the soundproof/dripproof structure of the embodiment of the present invention (with the cover closed), Figure 2 is a sectional view of the soundproof/dripproof structure of the embodiment of the present invention (with the cover open), and Figure 3 is FIG. 2 is a perspective view (when the cover is open) of the soundproof and drip-proof structure of the embodiment of the present invention.

In the figure, 11 is the printer, 12 is the paper before printing, 13 is the printing paper outlet, 14 is the paper after printing, 15 is the winding part, 16 is the cover, 17 is the soundproof rib, 18 is the drip-proof rib, and 19 is the cutter. , 20
is a hinge, and 21 is a paper cover.

The embodiment of the present invention is implemented as a soundproof and drip-proof structure for a small printer of a hand-held terminal.

As shown in FIG. 1, the soundproof and drip-proof structure of the embodiment of the present invention is as shown in FIG. The removed portion 15 is covered with a cover 16, and the printer 1 is
It is attached to the tip of 1. Here, the paper cover 2 further covers the roll paper portion of the paper 12 before printing.
1 is mounted so as to be rotatable in the direction of arrow B in FIG. When the cover 16 is closed, the drip-proof ribs 18 placed on both sides press and fix the paper cover 21, so that it does not open or close unnecessarily (see FIG. 3).

As shown in FIG. 3, the inner wall of the cover 16 is formed with uneven soundproof ribs 17 and drip-proof ribs 18. The soundproof ribs 17 serve to weaken the vibrations of printing transmitted to the paper, and also to reduce the contact area of the paper to reduce friction and improve the slippage of the paper.
The soundproof ribs 17 include a plurality of ribs with shallow irregularities formed in the paper width range along the direction in which the paper moves. The drip-proof ribs 18 are deeply uneven ribs formed on both sides through which the paper passes, and even if water droplets enter through the gap in the cover 16, these ribs block them and prevent the paper etc. from getting wet. Further, the cover 16 is configured to be openable and closable using a hinge 20.

The soundproof and drip-proof structure constructed as described above was used in the following manner.

First, attach the cover 16 to the hinge 2 as shown in FIG.
0 in the direction of arrow C, and then open the paper cover 21 in the direction of arrow B to set the pre-print paper 12 in the printer 11. The paper cover 21 and cover 16 are closed, and printing is started in the state shown in FIG. The roll paper of the pre-print paper 12 is supplied to the printer 11 while rotating in the direction of arrow A, and the paper printed by the printer 11 comes out from the print paper outlet 13. At this time, the vibration of the printer head is transmitted to the paper and resonates, making the printing sound louder.
However, the whole thing is covered with the cover 16,
The printed paper is stored in the winding section 15 along the moving path shown by the dotted line, but since it moves along the soundproof ribs 17 along the way, the soundproof ribs 17 weaken the vibrations transmitted to the paper. Reduce noise. In addition, the unevenness of the drip-proof ribs 18 also has a soundproofing effect, so that the sound can be further reduced.

Even when the printer is used outdoors in rainy weather, the cover 16 is provided over the printer part.
Furthermore, since drip-proof ribs 18 are formed on the inside, it is possible to reliably prevent water from entering and prevent paper and machinery from getting wet.

After printing, open the cover 16 and remove the winding section 1.
The printed paper 14 stored in the holder 5 can be easily taken out.

In the embodiment of the present invention, the cover 16 is configured to be openable and closable using the hinge 20, but it may also be configured such that the cover 16 can be attached and detached to take out the paper 14 after printing.

[Effect of idea]

As described above, the soundproof and drip-proof structure of the HHT printer of the present invention makes it possible to reduce the printing noise of the printer and to improve the drip-proofness of printing paper, etc.
