Patent JP-S5970576-A (JP)
Title: Ink jet recorder
Inventor: ITOU TOORU
IPC: B41J2/175
Filed: 1982-10-15
Abstract: PURPOSE:To prevent an ink from wastefully flying out of a head nozzle and air from being sucked into the nozzle, by a method wherein a pipe proximate to a head is constituted of a soft elastic material in a bent pipe form to absorb pressure variations, and resistance is given to a rapid flow of an ink. CONSTITUTION:When intermittent feeding is started or stopped, an inertial force due to acceleration is exerted on the ink 3 contained in the head 5 or a pipe 11. By the inertial force, positive and negative pressure variations are induced in the ink 3 in the pipe 11 and the head 5. On the other hand, a coil form pipe 15 is provided at an intermediate part of the pipe 11 in proximity to the head 5, and pressure varitions are absorbed by flexure of an elastic member constituting the pipe 15. In addition, the ink 3 tending to move the pipe 11 under inertia receives a large flow resistance in the coil form pipe 15 since the movement due to inertia is more rapid than the normal feed of the ink for printing, and movement of the ink 3 is hindered.
