A roll feeding device, including: a support shaft (10), equipped with a longitudinal axis (Y) and provided to support one or more rolls (C), which includes a first end (11) and a second end (12); one or more pusher arms (20), movable along a direction parallel to the longitudinal axis (Y) in both directions, each of which is movable between an active position, in which it is arranged alongside a roll (C) and can come into contact with it during a movement parallel to the longitudinal axis (Y), and an inactive position.

Provided is a glass roll (1), including: a winding core (2); a film body (F), which is taken up into a roll shape by the winding core (2), and includes a glass film (3) and a scattering prevention film (7) having a smaller width than the glass film (3); and flanges (8) which are mounted to the winding core (2), and which are arranged on both sides of the film body (F) in a width direction. The film body (F) includes a detachable displacement prevention film (6) on a termination end portion side of the glass film (3) in a take-up direction. The displacement prevention film (6) includes a wide portion (6a) having a lager width than the glass film (3).

A printing apparatus is configured to perform in a first mode in which a second driving unit drives a second spool to feed out a sheet from a roll to a printing unit via a second guide, the printing unit performs printing on the fed sheet, and a basket unit receives the printed sheet printed on by the printing unit, and a second mode in which a first driving unit drives a first spool to feed the out the sheet from a roll to the printing unit via a first guide, the printing unit performs printing on the fed sheet, and the second driving unit drives the second spool to wind up the printed sheet printed by the printing unit as a roll.

A winding device includes a winding shaft that rotates and winds a print medium conveyed from a printing device having a conveyance roller that conveys the print medium, a gear, and a motor driving the conveyance roller and the gear. The winding device also includes a power transfer mechanism to connect to the gear and transfer power to the motor, and a lever disposed between the winding shaft and the conveyance roller in a conveyance path in a configuration in which the winding device is connected to the printing device. The lever may be moved between a first position in which the print medium bends and a second position in which the print medium bends at a shallower angle than at the first position.

A paper compartment in which roll paper can be held has an opening positioned along the second axial end of the roll paper and a wall positioned along the first axial end of the roll paper in the axial direction. The paper loading member can be removably installed in the paper compartment through the opening. The paper loading member has a flange and a roll support member that projects from the flange and is inserted into the paper. When roll paper is held in the paper compartment, the paper loading member is installed in the paper compartment with a first side of the flange contacting the first axial end of the paper, and the roll support member is inserted into the roll paper. When the paper loading member is installed in the paper compartment, the first side of the flange faces the opening.

A media guide is provided for use in printer. Media guide includes main body portion having internal bore configured to be disposed around media spindle and guide member connected to main body portion. Guide member is configured to extend outwardly from main body portion to extended position and to retract toward main body portion to collapsed position. Method for using media guide is also provided. Media guide is disposed on media spindle such that media spindle extends through internal bore of main body portion and is positioned and locked at selected position along length of media spindle. When media roll is disposed on media spindle, guide member is extended to extended position. When media roll is configured to be one of loaded onto or unloaded from media spindle, guide member is retracted to collapsed position.

A material strip collection mechanism coiling fed material strip on a reel includes a vertically positioned reel bracket rotatable about a vertical axis between a first configuration and a second configuration. The mechanism further includes a first arm holding the reel and a second arm each rotatable to drive the reel and coil the material strip on the reel. With the reel bracket in the first configuration, the first arm is in a material strip collection position to allow the material strip to be coiled on each empty reel held by the first arm to form a full reel, while the second arm is in a standby position to allow the full reel held by the second arm to be replaced with a new empty reel.
