Further, as the time belt 9 rotates at regular intervals in accordance with the rotational force of the carriage motor 4b, the carrier 4 of the carriage mechanism 4a moves left and right.

The carrier 4 to be moved is guided and moved by the guide shaft 5. As the carrier 4 is moved in this way, ink is sprayed onto the paper supplied by the rotational force of the line feed motor 3a in the ink cartridge 6 (shown in FIG. 1) mounted on the carrier 4. Done.

After the ink cartridge 6 performs the left and right reciprocating motion once on the carrier 4, the ink cartridge 6 again prints the next line of paper according to the rotational force of the carriage motor 4b. At this time, the paper is moved by the rotational force of the line feed motor 3a.

This operation may be repeated to complete the print job, or when the power is turned off, the carriage mechanism 4a may prevent the cartridge from exposing the head of the ink cartridge 6 to the home assembly 8. While pushing the rib (Rib) of the head capping (Capping) operation is made.

This head capping operation will be described in detail with reference to the accompanying drawings.

FIG. 3 is an exploded view illustrating in detail the home assembly of the conventional inkjet printer shown in FIG. 2. As shown, the carriage mechanism 4a (shown in FIG. 2) is used to prevent the head from clogging the head exposure of the ink cartridge 6 (shown in FIG. 1). While moving the head cap 8a up and down by a capping motor (not shown) which drives the cap 8a, the nozzle (not shown) of the head of the ink cartridge 6 is moved. Capping operation is performed to prevent clogging. In addition, the ink on the head of the ink cartridge 6 is removed by the wiper 8c. The home assembly 8 is fixed to the main frame 8e through the fixing component 8d.

At this time, since a capping operation is performed by friction between the carriage mechanism 4a and the ribs 8b of the home assembly 8, noise occurs and capping occurs. There is a problem that the manufacturing cost increases when producing a product as a motor is used.

Accordingly, an object of the present invention is to provide a low noise home capping device for reducing noise due to head capping by modifying a home assembly in order to solve the above problems.

The present invention for this purpose, the head for ejecting ink, the cap is slightly inclined to block the nozzle inlet of the head and the wiper to wipe the ink and the frictional force during the movement of the head Characterized in that composed of a Home Assembly (Rib) for forming a rib (Rib) for.
