ABSTRACT:
A service station device of a head for inkjet printer placed out of a printing area includes a wiper for cleaning the head, an operating lever operated by a carriage part moved to a service area, an elastic member for returning the operating lever when the carriage part is moved to a printing area, a rotating force transmitting part for changing the movement of the operating lever into a rotating force to transmit it, and a cap part reciprocating by the rotating force to be in contact with a head surface by ascending when the carriage part is moved to the service area. Here, a driving part for driving the wiper and cap is formed by a cleaning part having a wiper gear, the operating lever and the wiper, and a closing part having a cap gear, a vertical rack and the cap. A carriage moved side to side is utilized during printing to sequentially carry out the cleaning and closing functions. Thus, the structure is simplified and the assembling operation is shortened to improve the manufacturing efficiency while economizing the cost. Also, the simplified driving part enables to contrive minimization of the printer, and the stroke span of the driving part becomes short to reduce the cleaning and closing operation time, thereby devising fast printing operation and providing the inkjet printer with improved function.
