An ink jet recording apparatus according to Claim 59, wherein said cap member has a site arranged on said adhering member, and a hole portion communicated to the sucking means for suction of ink.
Claim 82
Dependent Claim 19 words
An ink jet recording apparatus according to Claim 59, wherein said recording head discharges ink by utilizing heat energy.
Claim 83
Dependent Claim 150 words
An ink jet recording apparatus equipped with an ink suction pump which performs discharge recovery treatment for maintaining the ink within the discharge port under a predetermined state by sucking ink from the discharge port of a recording head, wherein said ink suction pump is an ink suction pump which has a cylinder and a piston moving in a reciprocal fashion relative to said cylinder therein and performs suction of said ink and discharge of said sucked ink as accompanied with said reciprocal movement, an annular contact portion forming a route for said discharge, which, in the actuation according said suction, blocks the route for discharging said ink, and maintains a predetermined interval by separation in the actuation according said discharge, is provided at either the end surface of said piston or the end surface of the pushing member which pushes said end surface in the actuation of said suction.
Claim 84
Dependent Claim 150 words
An ink jet recording apparatus equipped with an ink suction pump which performs discharge recovery treatment for maintaining the ink within the discharge port under a predetermined state by sucking ink from the discharge port of a recording head, wherein said ink suction pump is an ink suction pump which has a cylinder and a piston moving in a reciprocal fashion relative to said cylinder therein and performs suction of said ink and discharge of said sucked ink as accompanied with said reciprocal movement, an annular contact portion forming a route for said discharge, which, in the actuation according said suction, blocks the route for discharging said ink, and maintains a predetermined interval by separation in the actuation according said discharge, is provided at either the end surface of said piston or the end surface of the pushing member which pushes said end surface in the actuation of said suction.
Claim 85
Dependent Claim 99 words
An ink suction pump having a cylinder and a piston which moves in a reciprocal fashion relative to said cylinder therein, which performs suction of ink and discharge of said ink sucked, wherein an annular contact portion forming a route for said discharge, which, in the actuation according said suction, blocks the route for discharging said ink, and maintains a predetermined interval by separation in the actuation according said discharge, is provided at either the end surface of said piston or tne end surface of the pushing member which pushes said end surface in the actuation of said suction.
Claim 86
Dependent Claim 99 words
An ink suction pump having a cylinder and a piston which moves in a reciprocal fashion relative to said cylinder therein, which performs suction of ink and discharge of said ink sucked, wherein an annular contact portion forming a route for said discharge, which, in the actuation according said suction, blocks the route for discharging said ink, and maintains a predetermined interval by separation in the actuation according said discharge, is provided at either the end surface of said piston or tne end surface of the pushing member which pushes said end surface in the actuation of said suction.
Claim 87
Dependent Claim 47 words
An ink jet recording apparatus according to Claim 64 or an ink suction pump according to Claim 65, wherein said annular contact portion is a rib provided on the end surface of said piston concentrically with said end surface, and the cross-section of said rib is semicircular.
Claim 88
Dependent Claim 48 words
An ink jet recording apparatus according to Claim 64 or an ink suction pump according to Claim 65, wherein said annular contact portion is a rib provided on the end surface of said pushing member concentrically with said end surface, and the cross-­section of said rib is semicircular.
Claim 89
Dependent Claim 19 words
An ink jet recording apparatus according to Claim 64, wherein said recording head discharges ink by utilizing heat energy.
