DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an OA
The present invention relates to a soundproof cover for a device. The printer device is provided with a soundproof cover covering the opening in order to reduce the noise generated inside from leaking out of the opening such as the printer paper passage.

[0002]

2. Description of the Related Art FIG. 8 shows a configuration in which a soundproof cover is arranged in a conventional OA device. FIG. 8A shows the case without the soundproof cover.

In FIG. 1, reference numeral 101 denotes an OA device (printer). Reference numeral 102 denotes a noise source (printing device).

[0004] Reference numeral 103 denotes an opening, which is a printing paper 104.
Outlet. 104 is a printing paper. For example, the printing paper 104 is supplied from the rear (the left side in the drawing) of the OA device 101, printed by the printing device 102, and discharged to the front (the right side in the drawing). In the printer 101, the printing device 102 generates noise when printing, so that the entire device is covered with a cover and is sound-insulated. However, printing paper 10
Since there is an opening 103 for discharging the nozzle 4, the noise generated in the noise source (printing device) 102 leaks out from the opening 103, and the sound insulation is not perfect.

FIG. 8B shows a case where a soundproof cover is provided. In the figure, the same numbers as those in FIG. 8A have the same configuration. Numeral 110 denotes a soundproof cover for insulating noise leaking from the opening 103.
