Description

[Detailed description of the invention] Industrial application field The present invention relates to a silencer box for printers that houses printers used in office printing equipment such as computers and word processors, and blocks the noise produced during printing. .

BACKGROUND OF THE INVENTION Among printers conventionally used as office printing devices, impact printers emit a loud and harsh sound when printing. Therefore, the printer is housed in a box to muffle the noise during printing, but in conventional noise-muffling boxes, the main body of the box is made of plywood with a thickness of about 20 mm, and urethane foam is pasted on the inside of the box. is generally known.

Problems that the invention aims to solve As mentioned above, when the box body was made of plywood with a thickness of about 20 mm, there was a problem that the overall weight would be heavy and the box would be large. As the box becomes larger, the installation space for the printer becomes a problem, so it is desired to make it as small as possible. Also,
Due to the thick board of the box body, heat dissipation is poor.
There is a problem in that when a printer is operated for a long time, heat tends to accumulate inside the box. There is a problem in that when heat builds up inside the box, it adversely affects the printer.

This invention solves these problems,
The purpose of this invention is to reduce the size of the silencing box, improve heat dissipation, and improve the silencing effect.

Means for Solving the Problem In order to solve this problem, the present invention includes a bottomed box main body having an opening at the upper end from near the rear end to the front end, and a box that is pivoted on the box main body and has an opening at the upper end. The lid body that opens and closes the opening is made of thick paper such as cardboard, and a sound insulating material made of foamed resin is attached to the inner surface of the box body and the lid body, and the lid body has a transparent window that allows the inside to be seen through. A plate is provided, and a reinforcing material having a U-shaped cross section for warping prevention is fitted onto the front and rear ends of the cardboard constituting the lid over almost the entire length in the left and right width directions.

Function: This structure is made of thick paper such as cardboard and sound insulating material attached to its inner surface, so it is thinner than the conventionally used plywood, making it lighter in overall weight and smaller in size. .
Furthermore, by reducing the thickness, heat dissipation can be improved. Furthermore, since both front and rear ends of the lid are fitted with reinforcing materials having a U-shaped cross section to prevent warping, the contact between the top opening on the box body side and the lid can be maintained over the entire circumference. It can be done evenly, prevents sound from leaking to the outside, and can be expected to have a sufficient sound deadening effect. Furthermore, since the main body box has a bottom, even if the printer is installed protruding from the stand, no sound will leak from the bottom. Furthermore, since the lid is provided with a transparent window plate, it is possible to see inside the box and check the operating status of the printer during printing.
