Carriage apparatus
A carriage guide surface for guiding a carriage traveling in a main scan direction, and a main scan direction regulating unit and a sub-scan direction regulating unit which position a print medium, are provided on the same member.
1. A carriage apparatus capable of mounting a processing unit which is configured to perform predetermined processing with respect to a sheet, the apparatus comprising:
a positioning unit configured to be able to abut against an end portion of the sheet and position the sheet in a direction orthogonal to a scanning direction of the carriage,
a guide unit configured to guide the carriage so as to be capable of moving forward and backward in the scanning direction of the carriage, wherein the guide unit includes a guide surface abutting on the carriage and regulating a position in a direction orthogonal to the scanning direction of the carriage, the guide surface having a surface perpendicular to a surface of the sheet positioned by the positioning unit; and
a biasing unit configured to bias the carriage against the guide surface,
wherein the positioning unit and the guide unit are integrally formed.
2. The carriage apparatus according to claim 1 , wherein the processing unit is a print unit configured to perform printing by ejecting liquid onto the sheet.
3. The carriage apparatus according to claim 1 , wherein the processing unit is a read unit configured to read an image printed on the sheet.
4. The carriage apparatus according to claim 1 , wherein the guide unit is capable of moving forward and backward on different paths.
5. The carriage apparatus according to claim 1 , further comprising a sheet biasing unit configured to bias the sheet with respect to the positioning unit.
6. The carriage apparatus according to claim 1 , further comprising a pressing unit configured to press the sheet in a direction perpendicular to a surface of the sheet that is subjected to processing by the processing unit.
7. The carriage apparatus according to claim 1 , wherein a correction unit configured to correct an inclination of the carriage is disposed in the guide unit.
8. A carriage apparatus capable of mounting a processing unit which is configured to perform predetermined processing with respect to a sheet, the apparatus comprising:
a positioning unit including an abutting portion for abutting an end portion of the sheet and positioning the sheet in a direction perpendicular to a scanning direction of the carriage; and
a guide unit configured to guide the carriage so as to be capable of moving forward and backward in the scanning direction of the carriage,
wherein at least a part of the guide unit is disposed vertically below the abutting portion.
