Portable image-forming device

A portable image-forming device, comprising:

• a housing in which an instant film is mountable;
• an exposure member, disposed in an inside of the housing, to move along a longitudinal direction of the housing;
• a pressurizing member, provided on one side of the exposure member, to pressurize the instant film such that a developing agent included in the instant film develops an exposed portion of the instant film;
• and
• a moving member to move the exposure member and the pressurizing member within the housing along the longitudinal direction of the housing,
• wherein the exposure member, the pressurizing member, and the moving member are integrally formed as a single body, such that movement of the moving member causes movement of the exposure member and the pressurizing member.

A portable image-forming device, comprising:

• a housing;
• an exposure member to expose an instant film disposable in an inside of the housing to a light radiating from a portable display device;
• a shading member to operate in association with the exposure member and to shield the instant film;
• a traction unit, connected to the exposure member, to move the exposure member to a pre-exposure position;
• a developing agent-spreading member including a plurality of rollers to spread a developing agent provided in the instant film over an exposed portion of the instant film;
• a driving unit, including a motor, to indirectly transmit power to the exposure member through the shading member and to directly transmit power to the developing agent-spreading member;
• a battery to supply power to the driving unit;
• a first sensor disposed at the pre-exposure position adjacent to the plurality of rollers to sense a position of the exposure member at a first position at which the exposure member starts exposure;
• and
• a second sensor disposed at a post-exposure position adjacent to the motor to sense a position of the exposure member at a second position at which the exposure member completes the exposure.

A portable image-forming device, comprising:

• a housing to accommodate an electronic device which displays an image;
• a traction unit to be engaged with the electronic device and to move in a first direction toward a pre-exposure position when the electronic device is inserted into the housing in the first direction;
• an exposure member to be engaged with the traction unit when the traction unit moves in the first direction and to move in the first direction along with the traction unit, to be released from the traction unit in response to the traction unit reaching the pre-exposure position, and when the exposure member is released from the traction unit, to move in a second direction, opposite of the first direction, toward a post-exposure position;
• and
• a developing agent spreader to spread a developing agent to a portion of an instant film exposed to light by the exposure member, the instant film being mountable in an inside of the housing.
