Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the structure of printer assemblies such as line printers and serial printers, and more particularly to the structure of printer desks that reduce noise generated by printers.

Conventionally, this type of printer console 10 has a line printer, a serial printer, etc. 11 as shown in FIG.
However, the structure was such that unprinted paper 12 and printed paper 12' were placed directly on the floor. Therefore, this structure has the drawback that the noise generated from the printer is propagated through the printing paper 12, 12' or is radiated around the apparatus through the exhaust port (at the rear or bottom of the apparatus) for cooling the apparatus. .

SUMMARY OF THE INVENTION An object of the present invention is to provide a printer console having a structure that reduces the noise generated by the printer.

Another object of the present invention is to eliminate the drawbacks of the conventional printer by providing a housing for accommodating unprinted paper and printed paper, and a dedicated duct provided within the housing for discharging noise generated by the printer. An object of the present invention is to provide a printer assembly.

According to the present invention, there is provided a printer including a cooling fan provided at the upper part of the housing and generating a cooling air flow toward the bottom of the housing, and an outlet for the cooling air flow formed at the bottom of the housing. , a passageway opening formed on a mounting surface of the printer at a position facing the discharge port, a first passageway communicating with the passageway opening and extending toward opposite side plates below the mounting surface; and the first passageway. A printer assembly is obtained, characterized in that it has a soundproof table having a duct having a second passage communicating with the first passage in a perpendicular direction and discharging the discharged airflow to the outside.

Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 29 shows an embodiment of the present invention. Figure 2a
, this printer console 20 is configured to mount a line printer or serial printer 11, and has side plates 21 and 22 attached to both sides, and a front door 23 attached to the front and back.
and rear door 24 constitute a casing, the inside of which is sealed from the outside.

The interior of the housing 20 accommodates unprinted paper 25 and printed paper 25', and is provided with a dedicated discharge duct 26 for discharging air that has cooled the interior of the printer 11 to the outside. There is.
The front door 23 is provided with a hinge (not shown) at one end so that it can be opened and closed. Furthermore, this front door 23 is provided with, for example, a glass 27 so that the inside of the housing, that is, the state in which paper is being used can be seen. Similarly, the side plates 21 and 22 are also provided with glass 28 so that the inside of the housing can be seen. Furthermore, the side plates 21 and 22 are connected to the duct 2.
An exhaust port 29 is provided so that the exhaust air from 6 is discharged to the outside (in the direction of arrow 30). Note that the exhaust from the exhaust duct 26 is through the rear door 24.
It may be discharged to the side, in which case the rear door 24 is provided with a discharge port (not shown).

FIG. 2b shows a cross section of the main part of the printer console with a printer mounted thereon, and FIG. 2c shows a cross section of the printer console along line A-A'. In FIGS. 2b and 2c, the printer 11 is provided with an insertion section 13 for inserting unprinted paper 25 and an ejection section 14 for discharging printed paper 25', which are further fed by a cooling fan 15 inside the printer. Exhaust port 16 for discharging air
is provided.

The printer console 20 includes a paper insertion section 13, a paper ejection section 14, and a cooling air exhaust port 16 of the printer 11.
Paper passage opening portions 31 and 32 and exhaust passage opening portions 33 are provided correspondingly to the paper passage openings 31 and 32, respectively.

The exhaust duct 26 is connected to the exhaust passage opening 33, extends toward the side plates 21 and 22 of the housing, and further extends toward the rear along the side plates 21 and 22.
The exhaust side of the exhaust duct 26 is connected to an exhaust port 29 near the rear of both side plates 21 and 22.

In this way, the printer console 20 allows the noise generated by the printer 11 to pass through the exhaust duct 26 to the exhaust port 29.
The noise is attenuated due to the exhaust passage having a 90° bend. Further, in the printer console 20, the noise generated by the printer 11 passes through the paper path openings 31, 32 and is transmitted to the paper sheets 25, 25, and is generated as noise, but the inside of the housing 20 is sealed from the outside. The generated noise is not radiated outside.

Note that when the printer console 20 is equipped with the printer 11, a rubber gasket 34, for example, is provided between the printer console and the printer, and an airtight cover 35 is provided at the rear of the printer where printed paper is discharged. This prevents the noise generated by the printer from leaking directly to the outside.

As explained above, the present invention has the effect of reducing the noise of a desk-top printer by arranging the entire printing paper within a housing and exhausting the paper through a duct.
