Abstract
A rotary blade cuts a photosensitive/pressure-sensitive recording medium by when slides in a widthwise direction of the recording medium. At this time, one terminal of an optical fiber moves ahead of the rotary blade while radiating an optical beam on a portion of the recording medium, so that microcapsules of the recording medium in the exposed portion are all hardened by react to the optical beam. Therefore, mechanical stress generated by the rotary blade does not rupture the microcapsules.
Claims14
An image forming device comprising:
- an image forming unit;
- a cutting unit that cuts a recording medium, the cutting unit comprising a frame extending in a first direction, a holder supported on the frame and reciprocally movable along the frame within a moving region defined by a first end and a second end, and a rotary blade rotatable mounted on the holder, the rotary blade cutting the recording medium having a width in the first direction by moving along the holder while rotating;
- and
- a cleaning member that is positioned in the vicinity of the frame and cleans the cutting unit when the cutting unit comes into contact with the cleaning member,
- wherein the cleaning member holds an agent that is transferred to the cutting unit when the cutting unit comes into contact with the cleaning member, the agent upon being supplied to the cutting unit forming a thin film of the agent on the cutting unit and performing one of preventing a foreign material from clinging to the cutting unit and dissolving tacky material contained on the recording medium.

An image forming device comprising:
- an image forming unit;
- a cutting unit that cuts a recording medium containing an adhesive material while sliding across the recording medium, the cutting unit comprising a frame extending in a first direction, a holder supported on the frame and reciprocally movable along the frame within a moving region defined by a first end and a second end, and a rotary blade rotatable mounted on the holder, the rotary blade cutting the recording medium having a width in the first direction by moving along the holder while rotating;
- and
- a supply unit that holds one of an agent that prevents a foreign material from clinging to the cutting unit and an agent that dissolves the adhesive material contained in the recording medium, the supply unit transferring the agent onto the cutting unit when the cutting unit comes into contact with the supply unit so as to form a thin film of the agent on the cutting unit.

An image forming device comprising:
- a transport unit that transports a photosensitive/pressure-sensitive recording medium in a first direction;
- a frame extending in a second direction perpendicular to the first direction;
- a cutting unit that is slidably supported on the frame and cuts down the photosensitive/pressure-sensitive recording medium by sliding along the frame;
- and
- a first exposure unit that radiates white light onto a portion of the photosensitive/pressure-sensitive recording medium, the first exposure unit being attached to the cutting unit such that when the cutting unit slides in the second direction, the first exposure unit moves with and ahead of the cutting unit while radiating the white light onto the portion of the photosensitive/pressure-sensitive recording medium.
2 more elements
An image forming device comprising:
- an image forming device;
- a transporting unit that transports in a first direction a pressure-sensitive recording medium having a thickness in a second direction perpendicular to the first direction;
- and
- a cutting unit that cuts the pressure-sensitive recording medium in a third direction perpendicular to the first direction and at an angle of between 30 degrees and 60 degrees with respect to the second direction.
