Abstract
A feed tray configured to accommodate a roll, in which a sheet-shaped medium is rolled in a roll shape, the feed tray includes: a support portion configured to contact an outer peripheral surface of a lower portion of the roll at two support positions with a lower end of the roll being interposed therebetween and to rotatably support the roll; and a path having an inlet disposed between the two support positions and configured to guide the sheet-shaped medium unrolled from the roll. The two support positions are shifted from each other in an upper-lower direction.
Claims25
A feed tray for use with an image forming apparatus, the feed tray configured to accommodate a roll, in which a sheet-shaped medium is rolled in a roll shape, the feed tray comprising:
- a support portion, comprising two support rollers each configured to contact an outer peripheral surface of a lower portion of the roll at a different one of two support positions with a lower end of the roll being interposed therebetween and to rotatably support the roll;
- a member, contactable with the roll, and arranged at a location downstream with respect to the two support rollers in a direction in which the sheet-shaped medium unrolled from the roll is fed, the member configured to limit a loosening of the roll;
- and
- a path having an inlet disposed between the two support positions and configured to guide the sheet-shaped medium unrolled from the roll,
- wherein the two support positions are shifted from each other in an upper-lower direction.
A feed tray for use with an image forming apparatus, the feed tray configured to accommodate a roll, in which a sheet-shaped medium is rolled into a roll shape, the feed tray comprising:
- a support portion configured to rotatably support the roll and comprising a support base;
- and
- a contact member configured to contact at least a part of an outer peripheral surface of a lower portion of the roll and to restrict a movement of the roll in a rotation direction,
- wherein the contact member is disposed in a recessed portion at a center of the support portion in an axial direction of a rotation of the roll.
An image forming apparatus comprising:
- a feed tray configured to accommodate a roll, in which a sheet-shaped medium is rolled in a roll shape, the feed tray comprising:
- a support portion, comprising two support rollers each configured to contact an outer peripheral surface of a lower portion of the roll at a different one of two support positions with a lower end of the roll being interposed therebetween and to rotatably support the roll;
- a member, contactable with the roll, and arranged at a location downstream with respect to the two support rollers in a direction in which the sheet-shaped medium unrolled from the roll is fed, the member configured to limit a loosening of the roll;
- and
- a path having an inlet disposed between the two support positions and configured to guide the sheet-shaped medium unrolled from the roll,
- wherein the two support positions are shifted from each other in an upper-lower direction,
- a conveyance mechanism configured to convey the sheet-shaped medium of the roll accommodated in the feed tray;
- an image forming device configured to form an image on the sheet-shaped medium conveyed by the conveyance mechanism;
- and
- a housing configured to accommodate the conveyance mechanism and the image forming device, the feed tray being attachable to and removable from the housing.
An image forming apparatus comprising:
- a feed tray configured to accommodate a roll, in which a sheet-shaped medium is rolled into a roll shape, the feed tray comprising:
- a support portion configured to rotatably support the roll and comprising a support base;
- and
- a contact member configured to contact at least a part of an outer peripheral surface of a lower portion of the roll and to restrict a movement of the roll in a rotation direction,
- wherein the contact member is disposed in a recessed portion at a center of the support portion in an axial direction of a rotation of the roll,
- a conveyance mechanism configured to convey the sheet-shaped medium of the roll accommodated in the feed tray;
- an image forming device configured to form an image on the sheet-shaped medium conveyed by the conveyance mechanism;
- and
- a housing configured to accommodate the conveyance mechanism and the image forming device, the feed tray being attachable to and removable from the housing.
