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] 1 is a perspective view showing a cleaning device in the inkjet printer of this example and an inkjet head mounted on a carriage at a position facing the cleaning device. FIG. 2 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 inkjet head 2 is mounted on the carriage 82 with the nozzl...

Abstract

The invention provides a cleaning device for a ink-jet printer. The device comprises a cleaner rod of a flexible scraper for wiping a nozzle surface of an ink-jet head, a locking rod for locking the ink-jet head 2 and a clutch lever. While converting the rotary motion of the clutch lever into the reciprocating motion of the cleaner rod and the locking rod through a cam mechanism, the rotary force is transmitted to the clutch lever through a friction transmission route and a gear meshing transmission route. The gear meshing transmission route is formed under the condition of wiping the flexible scraper arranged on the front end of the cleaner scraper by an auxiliary flexible scraper and moving at the same time. Because under the condition of wiping the flexible scraper by the auxiliary flexible scraper, through the meshing type transmission route, the driving force can be transmitted to the cleaner scraper, the flexible scraper can be moved 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 nozzle. [0004] A general...
