Abstract
A recording apparatus having a printing head, comprises a support having heating elements, a film being contacted the support to face the elements and having nozzle holes on a region facing the elements, an ink holder, arranged near the holes and on one of opposing surfaces of the film and the support, for holding externally supplied ink, and a vibrator for vibrating the support to supply ink to the holes from the ink holder through a gap between the opposing surfaces of the film and the support. In another embodiment a drive unit may reciprocally move the nozzle member in the alignment direction. In a further embodiment the drive unit may reciprocally move the film and spacer relative to the support and the ink supplier.
Claims28
A recording apparatus having a printing head, comprising:
- a heating means support member having a plurality of heating means;
- a film member which is in contact with said heating means support member to face said plurality of heating means and has a plurality of nozzle holes on a region facing said heating means;
- an ink holding portion, arranged near said plurality of nozzle holes and on one of opposing surfaces of said film member and said heating means support member, for holding externally supplied ink;
- and
- vibration generating means for vibrating said heating means support member to supply ink to said plurality of nozzle holes from said ink holding portion through a gap between the opposing surfaces of said film member and said heating means support member.
A recording apparatus having a printing head, comprising:
- a heating means support member having a plurality of heating means which are aligned in line;
- a nozzle member which is in contact with said heating means support member to face said plurality of heating means, has a plurality of nozzle grooves, which are open to its end face, on a region facing said heating means, and is movable in the alignment direction of said plurality of heating means;
- nozzle member drive means for reciprocally moving said nozzle member in the alignment direction;
- and
- ink supply means for supplying ink to said plurality of nozzle grooves.
A recording apparatus having a printing head, comprising:
- a heating means support member having a plurality of heating means;
- a film member which is in contact with said heating means support member to face said plurality of heating means, and has a plurality of nozzle holes on a region facing said heating means;
- a spacer member which is in contact with said film member on a side opposite to said heating means support member, is arranged near said plurality of heating means of said heating means support member, and has a predetermined thickness;
- reciprocal drive means for reciprocally moving said film member and said spacer member relative to said heating means support member;
- and
- ink supply means for supplying ink to said plurality of nozzle holes of said film member, and
- wherein said reciprocal drive means reciprocally moves said film member and said spacer member relative to said heating means support member, so as to reliably supply ink from said ink supply means to all of said plurality of nozzle holes of said film member, said plurality of heating means are selectively heated during the reciprocal movement, and ink ejected from the plurality of nozzle holes corresponding to the selected heating means is caused to become attached to a recording paper sheet, which is in contact with said spacer member and is separated from the surface of said film member by a predetermined distance by said spacer member, thereby performing a printing operation.
A recording apparatus having a printing head, comprising:
- a heating means support member having a plurality of heating means;
- a film member which is in contact with said heating means support member to face said plurality of heating means, and has a plurality of nozzle holes on a region facing said heating means;
- a spacer member which is in contact with said film member on a side opposite to said heating means support member, is arranged near said plurality of heating means of said heating means support member, and has a predetermined thickness;
- reciprocal drive means for reciprocally moving said film member and said spacer member relative to said heating means support member;
- ink supply means for supplying ink to a gap between said film member and said heating means support member;
- and
- ink storage means for storing the ink supplied from said ink supply means in the gap.
