Abstract
A printing head includes a reserving portion that reserves a predetermined amount of ink. A supply system of an ink jet printer is configured so that an ink housing portion constituting an ink supply source intermittently supplies ink to the reserving portion using appropriate timings. The housing portion housing ink to be supplied to the head is located, acrossing an area where a printing is performed onto a sheet by the head, in a space opposite to a space in which the head is scanned. The housing portion is moved to or from the scanning space of the head so as to be joined to the head as required for an ink supply. That is, ink is intermittently supplied properly by moving the ink supply side to the joint position without moving the head. This provides an ink jet printer that does not affect the mounting accuracy of the head.
