Abstract
A supply apparatus including: a supply member that contacts a print medium and feeds out the print medium; a drive transmission unit configured to transmit rotation of a drive shaft to the supply member; and an arm member that supports the supply member and the drive transmission unit and rotates around a predetermined axis, wherein a contacting position between the supply member and the print medium is switched to any position of an upstream side or a downstream side in the feeding-out direction depending on a rotating position of the arm member.
Claims23
A supply apparatus comprising:
- a first supply member that contacts a print medium at a first position and feeds out the print medium;
- a second supply member that contacts the print medium at a second position located upstream of the first position in the feeding-out direction and feeds out the print medium;
- a drive transmission unit configured to transmit rotation of a drive shaft to the first supply member and the second supply member;
- an arm member that supports the first supply member, the second supply member and the drive transmission unit and rotates around a predetermined axis, and
- a control unit that switches contacting state between a first contacting state in which the first supplying member contacts with the printing medium and the second supplying member does not contact with the printing medium and a second contacting state in which the first supplying member does not contact with the printing medium and the second supplying member contacts with the printing medium.
A method for supplying a print medium in a supply apparatus including a first supply member that contacts a print medium at a first position and feeds out the print medium, a second supply member that contacts the print medium at a second position located upstream of the first position in the feeding-out direction and feeds out the print medium;
- a drive transmission unit configured to transmit rotation of a drive shaft to the first supply member and the second supply member, and an arm member that supports the first supply member, the second supply member and the drive transmission unit and rotates around a predetermined axis, comprising the step of:
- switching, by a control unit, a contacting state between a first contacting state in which the first supplying member contacts with the printing medium and the second supplying member does not contact with the printing medium and a second contacting state in which the first supplying member does not contact with the printing medium and the second supplying member contacts with the printing medium.
A supply apparatus comprising:
- a first supply member that contacts a print medium and feeds out the print medium;
- a second supply member that contacts the print medium and feeds out the print medium;
- a support member that supports the first supply member and the second supply member;
- a separation inclined surface that applies a resistance on a front end of the print medium fed out by the first supply member or the second supply member;
- and
- a control unit that switches a contacting state between a first contacting state in which the first supplying member contacts with the printing medium at a first position and the second supplying member does not contact with the printing medium and a second contacting state in which the first supplying member does not contact with the printing medium and the second supplying member contacts with the printing medium at a second position that is farther away than the first position in a distance from the separation inclined surface.
A printing apparatus comprising:
- a first supply member that contacts a print medium at a first position and feeds out the print medium;
- a second supply member that contacts the print medium at a second position located upstream of the first position in the feeding-out direction and feeds out the print medium;
- a drive transmission unit configured to transmit rotation of a drive shaft to the first supply member and the second supply member;
- an arm member that supports the first supply member, the second supply member and the drive transmission unit and rotates around a predetermined axis;
- a control unit that switches a contacting state between a first contacting state in which the first supplying member contacts with the printing medium and the second supplying member does not contact with the printing medium and a second contacting state in which the first supplying member does not contact with the printing medium and the second supplying member contacts with the printing medium;
- and
- a printing unit that performs a print on the print medium supplied from the supply apparatus.
A supply apparatus comprising:
- a supply member that contacts a print medium and feeds out the print medium;
- a support member that supports the supply member;
- a separation inclined surface that applies a resistance to a front end of the print medium fed out by the supply member;
- and
- a control unit that switches a contacting state between a first contacting state in which the supplying member contacts with the printing medium at a predetermined position and a second contacting state in which the supplying member contacts with the printing medium at a position further from the separation inclined surface than the predetermined position by changing a rotating direction of a drive shaft.
A supply apparatus comprising:
- a supply member that contacts a print medium and feeds out the print medium;
- a drive transmission unit configured to transmit rotation of a drive shaft to the supply member;
- an arm member that supports the supply member and the drive transmission unit and rotates around a predetermined axis, and
- a control unit that switches a contacting state between a first contacting state in which the supplying member contacts with the printing medium at a predetermined position and a second contacting state in which the supplying member contacts with the printing medium upstream of the predetermined position in the feeding-out direction by changing a rotating direction of the drive shaft.
