Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a printer such as a serial printer having an improved printer cover.

[0002]

[Prior art]

 Some recently developed printers have multiple paper feed openings in consideration of user friendliness. Especially, as shown in Fig. 5, 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. 5 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. Reference numeral 2 is a paper discharge opening, 6 is a carriage, 7 is a frame, and 8 is a window.

In some conventional printers, as shown in FIG. 5, no cover is attached to any of the paper feed openings 1a, 1b, and 1c.

Further, as seen in the actual flat sheet 3-81747 of FIG. 6, there is a case where a paper feed opening cover 16 having a paper guide rib 16b provided in parallel with the paper feeding direction is attached to the front paper feed opening 1b. It was In FIG. 6, reference numeral 9 is a paper sheet, 9a is a continuous paper perforation, 13 is a printer case, 16c is a cover hinge, and 16d is a cover fixing claw.

[0008]

[Problems to be solved by the device]

 However, in a printer without a cover for the paper feed opening as shown in FIG. 5, 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. Even in this case, the printing sound always leaks to the front of the printer, and the noise emission to the operator in front of the printer increases.

As shown in FIG. 6, even when the paper feed opening cover 16 is attached to the printer case 13 with the front paper feed opening 1b being closed, sound is generated from the upper and lower gaps of the paper feed opening cover 16. Leakage occurs and sound insulation is not sufficient. If a sound absorbing material is attached to the cover 16 in order to improve the sound insulation, there is a problem that the sound absorbing material has a large frictional resistance on the surface and the feedability is deteriorated.

In view of the above points, the present invention has an object to provide a printer having a paper feed opening cover with a simple structure and sufficient sound insulation and paper feedability.

[0011]

[Means for Solving the Problems]

 In order to solve the above problems, the printer of the present invention is a printer having a paper feed opening in front of the printer case, in which a printer cover that can be opened and closed is installed in the paper feed opening, and the printer is provided on the back side of the printer cover. It is characterized by the provision of ribs that have a minute gap from the printer case when the cover is closed.

[0012]

【Example】

 Embodiments of the present invention will be described below with reference to the drawings.

FIG. 2 is a sectional view of the printer of FIG. 1. 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 plate 11, is fed by the platen 3 and the roller 5, and is ejected from the paper ejection 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 paper 9 (numbers, letters, etc., as well as dots). A wide range of concepts including graph printing etc.) In FIG. 1, reference numeral 7 is a frame, 12 is a paper guide plate, 16 is a paper feed opening cover, and 16b is a paper guide rib.

2 is a perspective view of the front paper feed opening of the printer of the present invention, FIG. 3 is a cross-sectional view of the front paper feed opening 1b showing the paper feed opening cover 16 in an open state, and FIG. 3 is a sectional view showing a state in which the paper feed opening cover 16 is closed in FIG. 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. In combination with the hinge 13a on the printer case 13 side provided at the opposite position, it serves as the rotation axis of the paper feed opening cover 16. The paper feed opening cover 16 is provided with a cover fixing claw 16d, and when the paper feed opening cover 16 is closed, it is engaged with the printer case 13 by utilizing the elastic deformation of the cover fixing claw 16d. In the figure, 9a is a continuous paper perforation, 16a is a sound insulation rib, 16b is a paper guide rib, 16c is a cover hinge, and 16d is a cover fixing claw.

On the back surface of the paper feed opening cover 16, a plurality of paper guide ribs 16b are provided in parallel with the paper feed direction, and a sound insulation rib 16a, which is a feature of the present invention, is provided vertically to the paper guide rib 16b. There is. The sound insulation ribs 16a are provided at the upper and lower ends of the paper feed opening cover 16 one by one. As shown in FIG. 4, the sound insulation rib 16a is arranged at a position having a minute gap 17 with respect to the printer case 13 when the paper feed opening cover 16 is closed.

Next, the operation and effect of the above-described components will be described.

First, when the paper is fed from the front opening 1b, the paper feeding opening cover 16 opens downward as shown in FIG. 3, which impedes the view and operation of the user when setting the paper. Never becomes. Further, the contact surface of the paper guide rib 16b with the paper 9 is formed smoothly, so that the perforation 9a of the continuous paper is not caught and the paper feeding property is good. Further, in the present invention, since the sound absorbing material is not used, the cost is low, and the paper feeding property is not deteriorated due to the friction load of the sound absorbing material.

Next, when paper is fed from a place other than the front opening 1b, that is, when the paper is used with the paper feeding opening cover 16 closed, as shown in FIG. Since the sound insulation rib 16a is provided so as to have a minute gap 17 with the printer case 13, the gap between the paper feed opening cover 16 and the printer case 13 can be reduced. Therefore, sound leakage from the gap between the paper feed opening cover 16 and the printer case 13 can be prevented, and sufficient sound insulation can be provided.

[0019]

[Effect of device]

 According to the present invention, a cover is provided in the opening for feeding paper from the front, and a rib is provided inside the paper feed opening cover, which has a minute gap with the printer case when the feed opening cover is closed. This makes it possible to reduce the gap between the paper feed openings. Therefore, it is possible to prevent sound leakage from the gap, and thus it is possible to obtain sufficient sound insulation. Further, since the above-mentioned effect can be obtained without using the sound absorbing material, the structure is simple, and the paper feeding property is not deteriorated due to the frictional load of the sound absorbing material.
