Abstract (en)

[origin: EP0765751A1] The present invention relates to an ink jet recording apparatus which comprises: a recording head (7) being communicated with an ink tank via an ink supply member and being responsive to a print signal for spouting ink drops from nozzle openings to recording paper (6), capping means (80) abutting against a front of said recording head (7) for holding the nozzle openings in an airtight state, and suction means (13) for supplying negative pressure to said capping means (80) and sucking ink in said capping means (80) into a waste ink tank (30), said suction means (13) being formed as a peristaltic pump comprising an elastic tube and a plurality of rollers for rotating and driving a motor driving a paper feed roller (20) in one direction, thereby pressing against the tube for suction operation and rotating and driving the motor in another direction, thereby releasing pressure of pressing the tube for losing pump action, wherein after the suction process terminates, the rotation in said another direction is executed at a lower speed than the rotation in said one direction. <IMAGE>
