Embodiment Construction

[0069] A first embodiment of the present invention will be described below with reference to FIGS. 1-6.

[0070] As shown in FIG. 1 , an ink jet type recording device 11 as a liquid jet device has a frame 12 , a platen 13 suspended across the frame 12 , and an unillustrated paper feed mechanism equipped with a feed motor 14 . The platen 13 is a supporting mechanism for supporting the paper P, and the fed paper P driven by the feeding motor 14 is guided toward the top surface. The feed motor 14 drives unshown rollers to feed the paper P supported on the platen 13 in the direction of the arrow Y shown in FIG. 1 . A waste liquid tank 40 holding used ink is provided under the platen 13 .

[0071] A drive pulley 19 and a driven pulley 20 are fixed to the frame 12 . A reversible carriage motor 18 is coupled to a drive pulley 19 . A timing belt 17 extends around a pair of pulleys 19 and 20 . The bracket 16 is fixed to a timing belt 17 . In addition, a guide 15 extending parallel...

Abstract

A nozzle protecting device 30 of an ink jet type recording apparatus has a cap 46 which covers nozzles of a recording head and a cap support member 47 which is connected to the cap 45 via a spring member 80. The distance between the cap 46 and the cap support member 47 can be changed by elastic deformation of the spring member 80. A vent hole 54 is formed in the cap 46. A valve seat 56 which covers the terminal portion of the vent hole 54 is provided. A valve body 58 is rotatably attached to the lower portion of the cap 46. The valve body 58 selectively abuts on and parts from the valve seat 56 in accordance with the distance between the cap 46 and the cap support member 47. As a result, the inside of the cap 46 is opened and closed to air via the vent hole 54.

Description

[0001] This application is a divisional case of the invention with the application number 03804476.5, the filing date being July 8, 2003, and the invention name being the rotor, drive conversion device, cleaning device, wiping device and liquid injection device. technical field [0002] The present invention relates to a rotor, a drive switching device, a cleaning device, a wiping device and a liquid ejecting device comprising these devices. Background technique [0003] As a conventional liquid ejecting device that ejects liquid to a target, for example, an inkjet type printer that prints graphics or the like by ejecting ink droplets onto a page. This type of printer has a carriage member having a recording head and a platen supporting an object such as paper. The recording head has a plurality of nozzles that eject ink. The paper is guided between the recording head and the platen, and ink is ejected onto the paper from the nozzles. In order to prevent ink from clogging ...
