Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cover for a serial printer.

[0002]

[Prior art]

 Some recently developed printers have multiple paper feed openings in consideration of user friendliness. Especially, as shown in Fig. 4, the front of the printer has good operability for the user. Many things can be seen to be fed from. The printer shown in FIG. 4 is capable of inserting paper 9 through the front paper feed opening 1b and the lower paper feed opening 1c in addition to the paper 9 that is inserted through the paper feed opening 1a at the rear of the printer, which has been conventionally used.

The paper 9 supplied from the rear paper feed opening 1 a is guided to the paper guide 10 and inserted between the platen 3 and the print head 4 to perform printing. The paper 9 on which printing has been completed is ejected to the outside of the printer case 13 through the paper ejection opening 2.

The sheet 9 fed from the front paper feed opening 1b is guided into the printer along the paper guide plate 11, and is guided to the paper guide plate 12 via the upper side of the lower paper feed opening 1c. Reach between the platen 3 and the print head 4.

Similarly, the sheet 9 inserted from the lower sheet feeding opening 1c hits the sheet guide plate 11, is guided by the sheet guide plate 12 between the platen 3 and the print head 4, and is printed. The paper is discharged from the paper discharge opening 2 to the outside of the printer case 13. In some conventional printers, as shown in FIG. 4, no cover is attached to any of the paper feed openings 1a, 1b, and 1c.

Further, as seen in Japanese Utility Model Laid-Open No. 3-81747 in FIG. 5, there has been a paper feed opening cover 16 provided with a paper guide rib 16b in the front paper feed opening 1b.

[0007]

[Problems to be solved by the device]

 However, in the printer described above that does not have a cover for the paper feed opening, even when the paper 9 is fed from other than the front paper feed opening 1b, that is, when the front paper feed opening 1b is not used. However, the print sound always leaks to the front of the printer, which increases noise emission to the operator located in front of the printer.

[0008] In addition, in the case of the actual Kaihei 3-81747, even if the paper feed opening cover 16 is attached to the front paper feed opening 1b as shown in FIG. 5, the paper feed opening cover 16 alone provides sufficient acoustic energy. The sound insulation was not sufficient because it could not be attenuated. It is easy to attach a sound absorbing material to the cover 16 in order to improve the sound insulation, but the sound absorbing material has a large surface frictional resistance, so that the paper feedability is poor, and it is not possible to achieve both sound insulation and paper feedability. It was difficult.

In view of the above points, the present invention has an object to obtain a paper feed opening cover 16 having sufficient sound insulation and paper feedability in the front paper feed opening 1b.

[0010]

[Means for Solving the Problems]

 In order to solve the above problems, the printer cover of the present invention is a printer that can feed paper from the front, and a printer cover that can be opened and closed is installed at the paper feed opening in front of the printer, and multiple paper guide ribs are provided on the back surface. It is characterized by having a sound absorbing material.

【Example】

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

FIG. 1 is a sectional view of a printer to which the present invention is applied. The printer case 13 has a rear paper feed opening 1a for feeding the 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 usage 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.

2 and 3 are a sectional view and a perspective view of the front paper feed opening 1b of the present invention. 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. The paper feed opening cover 16 is provided with a hinge 16d, which, in combination with a hinge 13a on the printer case 13 side provided at the opposite position, serves as a rotation axis of the paper feed opening cover 16. The paper feed opening cover 16 is provided with a cover fixing claw 16e, and the paper feed opening cover 16 is opened and closed by engaging with the printer case 13 using elastic deformation of the cover fixing claw 16e. The actual operation can be closed by putting a finger on the cover handle 16f 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.

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 supplying material 20 is attached between the plurality of paper guide ribs 16b. .

First, when the paper is fed from the front opening 1b, the paper feeding opening cover 16 opens downward, so that it does not hinder the user's view or 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 are not in 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 1b, the sound absorbing material 20 is attached to the back surface of the paper feeding opening cover 16, so that the paper feeding opening cover 16 should be used in a closed state. Since the sound source 20 absorbs the sound wave energy, sufficient sound insulation can be provided.

[0017]

[Effect of device]

 According to the present invention, a cover is provided in the opening for feeding paper from the front, ribs for guiding the paper and a sound absorbing material are provided inside the feed opening cover, and the paper guiding rib is higher than the sound absorbing material. It is possible to achieve both paper feedability and sound insulation at the front paper feed opening.
