Abstract
An inkjet printer 1 has an ink path 35 communicating with a printhead 12, and a choke unit 46 for closing the ink path 35. The choke unit 46 includes a diaphragm valve 75 that is part of the wall of the ink path 35, a disc moving mechanism 76, and a drive motor 47 as the drive source. The disc moving mechanism 76 moves the diaphragm valve 75 between a closed-channel position 75A in contact with an opposite wall part (bottom 67a of the cavity 67) of the wall opposite the diaphragm valve 75, and an open-channel position 75B separated from this opposite wall part. The disc moving mechanism 76 is located outside the ink path 35.
Claims5
An inkjet printer comprising:
- a printhead;
- an ink path arranged to connect the printhead to an ink cartridge;
- a diaphragm valve, the diaphragm valve forming a part of a wall of the ink path, the diaphragm valve including an annular rib disposed at center thereof;
- a disc moving mechanism configured to move the diaphragm valve, between a closed-channel position where the annular rib of the diaphragm valve is in contact with an opposite wall part opposite the diaphragm and interposes on the ink path and an open-channel position where the diaphragm is retracted from the opposite wall part, the disc moving mechanism moving the diaphragm from outside of the ink path;
- and
- a drive motor that drives the disc moving mechanism.
