Problems solved by technology

As a result, compared with the case where the two levers are moved by the power source through the respective power transmission paths, it is necessary to increase the stroke amount more than necessary, which is disadvantageous for the miniaturization of the cleaner device itself.

Embodiment Construction

[0065]Embodiments of an ink-jet printer equipped with a cleaning device applicable to the present invention will be described below with reference to the accompanying drawings.

[0066] Since the overall configuration of the inkjet printer is the same as that of conventionally known continuous inkjet printers, illustrations and descriptions of this part are omitted in this specification. Only the carriage carrying the cleaning device and the inkjet head is shown and described below.

[0067] figure 1 It is a perspective view showing a cleaning device in the inkjet printer of this example and an inkjet head mounted on a carriage facing the cleaning device, figure 2 It is an exploded perspective view showing main parts of the cleaning device.

[0068] First, referring to these figures, the overall configuration of the inkjet head 2 and the cleaning device 10 in the inkjet printer 1 of this example will be described. The nozzle face 3 of the inkjet head 2 is mounted on the ca...

Abstract

A cleaning device for cleaning an ink jet printer. The cleaning device includes the cleaner lever with an elastic blade which can reciprocate for wiping a nozzle surface of an ink-jet head, a lock lever for fixing the printing head and a clutch lever provided with a gear part engaging with the levers. A butting cam part can shift rotary movement of the clutch lever to reciprocating movement of the cleaner leverand the lock lever, at the same time, transfer motive power to the clutch lever by transfering routes of friction and gear engagement. Route of gear engagement is formed as follows: in one side of the gear, an elastic blade wipes the elastic blade wipes mounting on the front patr of the cleaner blade, and another side of the gear keeps moving. Due to the the sub-elastic blade wipes the elastic blade and based on the route of gear engagement, motive power can be transfered to the clutch lever. Thus, the elastic blade can move smoothly.

Description

field of invention [0001] The invention relates to a cleaning device for wiping the nozzle surface of an inkjet head in an inkjet printer, and an inkjet printer with the cleaning device. Background technique [0002] An inkjet printer is a device that discharges ink droplets from the nozzles of an inkjet head to print on recording paper. Once clogging occurs in each ink nozzle, the printing quality will deteriorate, and even printing will become impossible. Ink nozzle clogging occurs when the ink in the ink nozzle dries up, its viscosity increases, or when paper dust adheres to the nozzle surface formed by the ink nozzle arrangement. [0003] Therefore, the inkjet printer is generally equipped with a cleaning device, and the carriage carrying the inkjet head is regularly moved to the cleaning device at a position outside the printing range, and the cleaning device wipes the nozzle surface and makes the viscosity increase. Ink is expelled from the n...
