Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a serial printer or the like having an improved printer cover.

[0002]

[Prior art]

 Some recently developed printers have multiple openings in consideration of user friendliness. Especially, even at the paper feed opening, it is easy for the user to feed from the front of the printer. Many things can be seen on paper.

Some conventional printers have a paper feed opening cover 16 attached to the front paper feed opening 1b as seen in Japanese Utility Model Laid-Open No. 3-81747 shown in FIG. In FIG. 4, the paper feed opening cover 16 has a paper guide rib 16b, a cover hinge 16c, and a cover fixing claw 16d, and is installed at a predetermined cover angle 16a. The paper 9 is provided with continuous perforations 9a. Reference numeral 13 is a printer case, and 1b is a front paper feed opening.

[0004]

[Problems to be solved by the device]

 However, in the printer shown in FIG. 4, when the paper feed opening cover 16 is used with the paper feed opening cover 16 closed, even if the paper feed opening cover 16 is attached to the front paper feed opening 1b, sound leaks from the gap of the paper feed opening cover 16. And the sound insulation was not sufficient. In order to reduce the sound leakage, it is necessary to improve the dimensional accuracy of the printer case 13 and the paper feed opening cover 16, which reduces the yield of parts. Even if it could be machined with high accuracy, it is difficult to maintain the airtightness because the member is deformed by the opening and closing operation.

In view of the above points, an object of the present invention is to provide a printer provided with a printer cover having a sufficient sound insulating property at the opening at low cost.

[0006]

[Means for Solving the Problems] In order to solve the above problems, a printer of the present invention is a printer in which an openable / closable printer cover is installed in a printer case opening, and the printer cover is provided on the back surface of the printer cover. A sound absorbing material is provided so as to contact the printer case in a closed state.

【Example】

 An embodiment of the present invention will be described with reference to FIGS. 1, 2 and 3.

FIG. 1 is an explanatory view of an embodiment of the printer of the present invention, and shows a sectional view of a printer in which a paper feed opening cover 16 which is a printer cover is applied to a front paper feed opening 1b. The printer case 13 has a rear paper feed opening 1a for feeding paper 9, a front paper feed opening 1b, and a lower paper feed opening 1c, which can be arbitrarily selected by the user depending on the use environment. The paper 9 inserted through each paper feed opening moves along the paper guide 10 and the paper guide plates 11 and 12, and is fed by the platen 3 and the roller 5 and discharged from the paper discharge opening 2. A print head 4 is arranged so as to face the platen 3, and the print head 4 is mounted on a carriage 6 that can reciprocate in the axial direction of the platen 3 and prints on a sheet 9. Reference numeral 7 is a frame, 16 is a paper feed opening cover, and 16b is a paper guide rib.

2 and 3 are explanatory views of the printer of the present invention, showing a cross-sectional view and a perspective view of the front paper feed opening 1b in which the paper feed opening cover 16 as a printer cover is installed. . A lower opening paper feed opening cover 16 is attached to the printer case 13 so as to be openable and closable in the front paper feed opening 1b. A hinge 16c is provided on the paper feed opening cover 16 and serves as a rotation axis of the paper feed opening cover 16 in combination with a hinge 13a on the printer case 13 side provided at an opposite position. The sheet feeding opening cover 16 is provided with a cover fixing claw 16d, and the sheet feeding opening cover 16 is opened and closed by engaging with the printer case 13 by utilizing elastic deformation of the cover fixing claw 16d.

A plurality of paper guide ribs 16b protruding from the sound absorbing material 20 are provided on the back surface of the paper feed opening cover 16, and the sound absorbing material 20 is attached between the plurality of paper guiding ribs 16b. Further, the sound absorbing material 20 is extended to the outer edge of the back surface of the paper feed opening cover 16 where the paper feed opening cover 16 and the printer case 13 are in contact with each other. It is deformed by compression until it engages with the case 13 and closes the front paper feed opening 1b. Since the sound absorbing agent 20 is formed of a sponge and has a large elastic deformation amount, high dimensional accuracy is not required between the paper feed opening cover 16 and the printer case 13. Therefore, the processing cost of the paper feed opening cover 16 and the printer case 13 can be suppressed.

The actual opening / closing operation can be closed by placing the finger on the cover handle 16e and pulling it toward you to open it, and pressing the surface of the paper feed opening cover 16 against the printer case 13 to close it.

When the paper is fed from the front opening 1b, the paper feeding opening cover 16 opens downward so that the user does not obstruct the view and operation when setting the paper. Further, the contact surface of the paper guide rib 16b with the paper 9 is formed smoothly, and the perforation 9a of the continuous paper is not caught, and the paper feeding property is good. Since the paper guide rib 16b is located at a position sufficiently higher than the sound absorbing material 20, the paper 9 and the sound absorbing material 20 do not come into contact with each other, and the sound absorbing material 20 does not deteriorate the sheet feeding property.

Next, when the paper is fed from other than the front opening 1 b, the paper feeding opening cover 16 is closed and used, and the sound absorbing member 20 attached to the back surface of the paper feeding opening cover 16 causes the sound wave of noise to be generated. Energy is absorbed. Further, since the sound absorbing material 20 extended to the outer edge of the paper feed opening cover 16 functions as a sound insulating packing in the gap between the printer case 13 and the paper feed opening cover 16, the paper feed opening 1b is completely sealed. , Prevent the noise inside the printer case 13 from radiating from the front of the printer.

Reference numeral 11 is a paper guide plate.

In the present embodiment, the sound absorbing material 20 also has a function as a sound insulation packing, so that the assembling cost can be reduced.

[0016]

[Effect of device]

 According to the present invention, the sound absorbing material is provided at the position where the cover on the back of the printer cover and the printer case are in contact with each other, and the sound absorbing agent is brought into contact with the printer case. Can be made. Moreover, since the sound absorbing material is used, high dimensional accuracy is not required for the printer cover and the printer case, which facilitates processing.
