Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a soundproof cover for a printer, and in particular to its use 1.
1. Regarding the structure of the anti-8 cover with excellent operability.

[FE Ming's technical blue version] Conventionally, printers have had problems with the noise generated when paper is fed by a tractor device or when printing is performed by a printing mechanism. Soundproof covers are used as a countermeasure to this problem. Figure 1 shows the structure of a conventional printer. The soundproof cover 1 is a top cover 3 provided on the top of the printer body 2.
One end thereof was joined to the upper surface of the tractor device 4, and the tractor device 4 was installed so as to be covered therewith.

(Problems with Back I; 1 Technology) In conventional printers with such a configuration, when replacing the ribbon or setting paper, it is necessary to remove the soundproof cover 1 and then remove the top cover 3. The drawback was that the operability was very poor.

[Purpose of the invention] The present invention has been made in view of the above points.

To provide a soundproof cover for a printer with good operability, which allows paper setting, ribbon replacement, etc. to be easily performed without removing the soundproof cover from the printer.

"Summary of the Invention" The present invention provides a pair of detachable mounting brackets on both sides of a tractor device of a printer, and attaches a soundproof cover rotatably via a fulcrum formed at one end of the mounting bracket. The desired purpose is achieved by configuring the horn bar to be attached to the inside of the opening formed on the top surface of the top cover that covers the top of the printer! This is Koshino.

[Embodiments of the Invention] Hereinafter, an embodiment of a soundproof cover for a printer according to the present invention will be described with reference to the drawings.

An embodiment of the present invention is shown in FIGS. 2 and 3.

In this figure, parts that are not shown in FIG. 1 and that are the same as those in the conventional example are not designated by the same numbers. Inside the printer body 2 are a ribbon cassette 5 containing an ink ribbon 5a and this ink ribbon 5.
A print head 7 that prints on the paper 6 via the paper 6, and a platen 8 that is provided opposite to the print head 7 and that wraps the paper 6 around the paper 6. Further, a tractor device 4 is provided on the upper part of the printer main body 2, and a sprocket 9 is housed in the tractor device 4, and the sprocket 9 is placed on the right side of the protrusion 9a. C1 and wind it around the platen 8 (,
H) The paper 6 and the paper sheets 1 to 9 are rotated to feed the paper.

A part of the top and side surfaces of the upper part of the Zolinta tree (A2) are covered with a top cover 3, and this 1~
Openings 3a are formed at positions where the tongue cover 3 contacts the 1 to 4 parts. Therefore, both sides of the tractor device 4 are located inside the top cover 3. Further, the top non-bar 3 rotates around a rotating shaft 2a provided in the printer body 2 to open the inside of the printer body 2.

Two pins 4 are provided on both sides of the tractor device 4, respectively.
a, 4b are implanted, and these two pins 4a, 4
A pair of mounting brackets 10 are provided on both sides of the tractor device 4, each having notches 10a and 10b that can be freely fitted into the mounting brackets 10a and 11b. A pin IOC is planted in one end of the J bracket 10 on the opposite side of the notches 10a and 10b, and is fitted into a hole in the mounting part 1a that is stepped on one end of the soundproof cover 1. The soundproofing material 1b is affixed to the entire back surface of the soundproofing cover 1, and covers the upper part of the tractor device 4 so that the soundproofing material 1b can be rotatably supported. Prevents noise and leakage to the outside.

Next is an embodiment of the present invention configured as described above.

The operation will be explained below with reference to FIGS. 4 and 5. When setting paper, close the soundproof cover 1 as shown in Figure 4.
When you pull the
Centered at c, [Shibogoo bar 1 rotates and sprocket 9
appears. Next, the lower projections 9a of the sprocket 9 are fitted into the holes formed on both sides of the paper 60, and the platen 8
6 rolls from the bottom () and then fit the upper protrusions 9a of the sprocket 9 into the holes on both sides of the paper 6. When the paper setting is completed in this way, lift the soundproof cover 1 and tilt it backwards. Then, it rotates around the pin 10c of the mounting bracket 10, so that a part of the tractor device 4 is covered.

When replacing the ribbon, as shown in FIG. 5, the top cover 3 is rotated about the rotating shaft 2a, lifted and tilted backward, and the upper part of the printer main body 2 opens, allowing the ribbon cassette to be replaced. At this point, since the tractor device 4 and the soundproof cover 1 are located inside the opening 3a formed in the upper part of the top horn bar 3, the soundproof cover 1 remains placed on the tractor device 4. The top cover 3 can be rotated.

After the ribbon replacement is completed, fold the top cover 3 forward and return it to its original position.
The inside of can be opened. In addition, the pair of mounting fittings 10 that rotatably support the soundproof horn bar 1 can be attached to the tractor device together with the soundproof cover 1 by attaching and removing the notches 10a and 110b formed in the fittings 10 from the pins 4a and 4b, respectively. It is important to be able to put on and take off.

[Effects of the Invention] As described above, the present invention is such that the soundproof cover of the printer is rotatably attached to the tractor device via the connecting fitting, and can be opened and closed back and forth inside the opening of the top cover. This eliminates the need to remove the soundproof cover when opening and closing the top cover when replacing the paper ribbon.
The effect is significant as the operability is significantly improved.
