Abstract

(57) [Summary] [Purpose] To enable even an inexperienced person to safely and easily clean ink stains on the circumferential surface of a platen roller in an inkjet printer. [Structure] A cleaning member is mounted on a carriage that can freely reciprocate in the direction of the rotational axis of the platen roller, and can be switched between a cleaning state in which it is in contact with the circumferential surface of the platen roller and a non-cleaning state in which it is separated from the circumferential surface of the platen roller. It is provided.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a cleaning device for an inkjet printer.

0002

[Conventional technology]

An inkjet printer that prints characters, figures, etc. by ejecting ink from a tiny nozzle. For example, where to load A4 size paper into the printer If you accidentally set B5 size paper, or if the paper exceeds the paper width, If you set the character spacing in the dimensions, the plate in areas that extend beyond the paper width may Ink is printed on the print roller.

0003 When printing is done on the platen roller in this way, the back side of the next paper to be fed will be Conventionally, the platen roller was rotated by hand to prevent it from getting dirty. Wipe off the ink adhering to the roller surface by applying cleaning paper or cloth to the ing.

[Problem that the idea aims to solve]

However, the cleaning work described above is quite troublesome for those who are not used to it. Furthermore, there is a risk of injuring fingers and fingers when moving hands in narrow spaces, so there is room for improvement. It was.

[0005] The present invention has been developed in view of the above circumstances, and is designed to make the platen roller safe. The purpose of the present invention is to provide a cleaning device that can be easily cleaned.

[0006]

[Means to solve the problem]

In order to achieve the above purpose, the present invention reciprocates in the direction of the rotation axis of the platen roller. A movable carriage is in a cleaning state in contact with the circumferential surface of the platen roller. and a non-cleaning state where the platen roller is separated from the circumferential surface. It is characterized by the provision of a replaceable cleaning member.

[0007]

[Effect]

According to the above characteristic configuration, the cleaning member is switched to the cleaning state. Rotate the platen roller and move the carriage in the direction of the rotation axis of the platen roller. The peripheral surface of the platen roller is cleaned by moving the platen roller to the position shown in FIG.

[0008]

【Example】

Hereinafter, embodiments of the present invention will be described based on the drawings. Figure 1 shows the printing section, Figure 2 1 shows the outline of an inkjet printer, and in these figures, 1 is the printer. The printer case 2 is a platen roller suspended horizontally on the side plate. A guide plate 3 and a pinch roller 4 are provided correspondingly.

[0009] 5 is a paper feed table, 6 is a paper feed roller, and 7 and 8 are for conveying the paper to the platen roller 2 side. It is a pair of guide plate and registration roller, and 9 is for ejecting paper with characters, figures, etc. printed on it. This is a pair of ejection rollers that take out the paper onto the tray 10.

0010 Reference numeral 11 indicates two keys horizontally suspended on the printer side plate in parallel with the platen roller 2. At the carriage stay, the rotation axis of the platen roller 2 is rotated along the carriage stay 11. A carriage 12 is horizontally suspended so as to be able to reciprocate in the linear direction, and this carriage 12 has a , a built-in ink type print cartridge 14 equipped with a print head 13 is connected to the print head 13. The head 13 is attached to the platen roller 2 in such a manner that it can be replaced freely. 15 is a carriage moving means, and a pair of pulleys 16 and 17, one of which is connected with a motor M, An endless toothed belt 18 is wound, and the carriage 12 is attached to a part of this belt 18. It consists of connecting.

[0011] 19 is a cleaning device attached to the side of the print cartridge 14, as shown in Figure 3. As shown in FIG. A cleaning member 21 such as felt is provided on the slide member 20 on which the , a pin b inserted through the elongated hole a is provided on the side of the cartridge case 22, The cleaning member 21 is in a cleaning state in which it is in contact with the circumferential surface of the platen roller 2. Automatically switches between X and non-cleaning state Y where the platen roller 2 is spaced It is currently configured.

0012 23 is a locking means for holding the cleaning member 21 in two states X and Y; Two recesses are formed in the attachment surface of the slide member 20 to the cartridge case 22. A ball d that forms an inlet c and is selectively engaged with the recess c; A spring e is provided in the cartridge case 22 to urge the rod d toward the recessed portion c. It consists of

[0013] Returning to Figure 1, 24 in the figure is a cleaner installed along with the cleaning device 19. Switch the cleaning member 21 to the cleaning state X using the cleaning operation switch. Then, when the switch 24 is turned on, the pin is held for a predetermined cleaning time. The chiller roller 4 is separated from the platen roller 2, and the platen roller 2 is rotated. At the same time, the carriage 12 moves back and forth, thereby mechanically moving forward. Ink stains on the circumferential surface of the platen roller 2 are cleaned.

[0014] In the embodiment, the cleaning device 19 is installed integrally with the print cartridge 14. , the carriage 12 can be indirectly switched to the above two states X and Y. Therefore, when the print cartridge 14 is replaced, the cleaning device 19 is also replaced. The configuration is such that it can be replaced, but the cleaning device 19 can be switched to two states X and Y. It may also be configured to be freely provided on the carriage 12 itself.

[0015] In this case, the cleaning member 21 may have an endless configuration, for example, and the cleaning member 21 may have an endless configuration. The cleaning action portion of the leaning member 21 may be configured to be sequentially changeable. desirable.

[0016] Further, when the cleaning operation switch 24 is turned on, reversibly, The cleaning member 21 is automatically switched to the cleaning state X. Alternatively, the rotation of the platen roller 2 and the movement of the carriage 12 may be controlled manually. It is also possible to take a form of cleaning that is carried out on a temporary basis.

[0017]

[Effect of the idea]

As explained above, the inkjet printer cleaning device according to the present invention According to and move the carriage in the direction of the rotation axis of the platen roller. This allows even inexperienced users to safely and easily remove ink stains from the surrounding surface of the platen roller. Can be easily cleaned.
