Inkjet apparatus
An inkjet apparatus includes, a carriage, mounting a head that discharges ink, configured to reciprocally move with respect to a sheet that receives the ink, a sensor unit, attached to the carriage, configured to read information from the sheet, and a rectifying skirt, attached to the carriage, having a rectifying surface that faces the sheet. The sensor unit is disposed above the rectifying skirt.
1. An inkjet apparatus comprising:
a carriage configured to move with a recording head mounted thereon, the recording head having a discharge port surface on which a plurality of discharge ports is provided;
a platen configured to support a sheet at a position facing the recording head;
a rectifying skirt provided at at least one of front and rear of the carriage in a moving direction of the carriage, and having a rectifying surface at a side facing the platen; and
a sensor attached to the carriage and configured to read information on the sheet supported by the platen, the sensor being provided at an opposite side away from the platen with respect to the rectifying skirt, and the sensor reading the information on the sheet through a hole formed in the rectifying skirt.
2. The inkjet apparatus according to claim 1 , wherein the sensor has an air inlet and sensing holes, and wherein, when the carriage moves, an air current arises in the sensor which is taken in from the air inlet and escapes from the sensing holes.
3. The inkjet apparatus according to claim 1 ,
wherein the rectifying skirt is provided at both the front and rear of the carriage in the moving direction of the carriage; and
wherein the sensor is provided at the opposite side away from the platen with respect to the rectifying skirt of either one.
4. The inkjet apparatus according to claim 1 , wherein a nozzle surface of the recording head and the rectifying surface is at approximately the same height from the sheet.
5. The inkjet apparatus according to claim 1 , wherein an end of the rectifying skirt contacts an abutting portion of the recording head, and wherein the rectifying surface extends from under the abutting portion to an outside of the carriage in a direction of the movement.
6. The inkjet apparatus according to claim 5 , wherein the rectifying skirt is supported by the carriage so that an orientation of the rectifying skirt is allowed to slightly change in a state where the recording head is not mounted on the carriage.
7. The inkjet apparatus according to claim 1 , wherein the rectifying surface has grooves formed thereon each extending in a direction intersecting with a nozzle array of the recording head.
8. An inkjet apparatus comprising:
a carriage, mounting a head that discharges ink, configured to reciprocally move with respect to a sheet;
a sensor unit, attached to the carriage, and configured to read information from the sheet; and
a rectifying skirt, attached to the carriage, having a rectifying surface that faces the sheet,
wherein the rectifying skirt has a hole formed between the head and the sensor unit in a direction of the reciprocal movement.
9. The inkjet apparatus according to claim 8 , further comprising an air inlet for taking in air when the carriage moves toward a predetermined one side in which the sensor unit is posterior to the head, and
wherein the air taken in from the air inlet escapes partially from the hole toward the sheet.
10. The inkjet apparatus according to claim 9 , wherein the sensor unit has an air inlet and sensing holes, and wherein, when the carriage moves toward the predetermined one side, an air current arises in the sensor unit which is taken in from the air inlet and escapes from the sensing holes.
