US 2021/0300067 A1 · PRINT MEDIUM FEEDING DEVICE

Abstract

A print medium feeding device removes a second sheet from a print medium that is in a state in which a first sheet, the second sheet, a the third sheet are superposed, superposes the first sheet and the third sheet, and feeds the first sheet and the third sheet to a printing device. The print medium feeding device includes: a first roller configured to come into contact with the third sheet and to be driven to rotate by movement of the third sheet; a second roller configured to come into contact with the first sheet and to be driven to rotate by movement of the first sheet; a roll-up member disposed upstream of the first roller and configured to roll up the second sheet; and a transmission mechanism configured to transmit a rotational force of the first roller to the roll-up member.

Dependent claims

A print medium feeding device configured to feed a print medium including a first sheet, a second sheet, and a third sheet to a printing device, the print medium being in a state in which the first sheet, the second sheet, and the third sheet are superposed, the print medium feeding device being configured to remove the second sheet from the print medium to superpose the first sheet and the third sheet, and to feed the first sheet and the third sheet that are superposed to the printing device, the print medium feeding device comprising:

a first roller configured to come into contact with the third sheet and to be driven to rotate by movement of the third sheet;
a second roller disposed at a position facing the first roller, and configured to come into contact with the first sheet and to be driven to rotate by movement of the first sheet;
a roll-up member disposed upstream of the first roller in a conveyance direction of the first sheet and configured to roll up the second sheet;
and
a transmission mechanism configured to transmit a rotational force of the first roller to the roll-up member.

2 more elements

a housing;
a mounting portion provided in the housing and configured to detachably mount the printing device;
an accommodation portion provided in the housing and configured to accommodate the print medium;
a guide mechanism disposed between the mounting portion and the accommodation portion and configured to sandwich the first sheet and the third sheet, the guide mechanism including a first roller configured to be driven to rotate by movement of the first sheet and the third sheet that is caused by a printing operation of the printing device;
a roll-up member disposed between the first roller of the guide mechanism and the accommodation portion and configured to roll up the second sheet;
a transmission mechanism configured to transmit a rotational force of the first roller to the roll-up member;
a first guide member provided in a first conveyance path, the first conveyance path extending from the accommodation portion to the first roller and being configured to allow the first sheet to be conveyed along the first conveyance path such that the first sheet moves on a first side in an orthogonal direction orthogonal to a longitudinal direction of the roll-up member;
and
a second guide member provided in a second conveyance path and a third conveyance path, the second conveyance path extending from the accommodation portion to the roll-up member and being configured to allow the second sheet to be conveyed along the second conveyance path, the third conveyance path extending from the accommodation portion to the first roller and being configured to allow the third sheet to be conveyed along the third conveyance path such that the third sheet moves on a second side opposite to the first side in the orthogonal direction with respect to the roll-up member.
