Abstract

A portable image-forming device includes a housing, an exposure member for exposing an instant film disposed inside of the housing by means of a light radiating from the screen of a portable display device, a shading member linked in movement with the exposure member so as to shade the instant film, a traction member connected to the exposure member so as to move the exposure member to a pre-exposure position, and a developing-agent-spreading member for spreading a developing agent, which is provided on the instant film, over the entire instant film. The traction member and the developing-agent-spreading member are manually operated by a user.

First claim

1 . A portable image-forming device, comprising:
a housing; an exposure member configured to expose an instant film disposable in an inside of the housing to a light radiating from a portable display device; a manually operable traction unit connected to the exposure member and configured to move the exposure member between a pre-exposure position and a post-exposure position; and a manually operable developing agent-spreading member configured to spread a developing agent provided in the instant film over an exposed portion of the instant film.

2 . The device as claimed in claim 1 , wherein the exposure member comprises:
a lens array; a frame configured to support the lens array; and a shutter slidably engaged with the frame, wherein the shutter closes the lens array in response to the exposure member moving to the pre-exposure position and opens the lens array in response to the exposure member moving from the pre-exposure position to the post-exposure position.

3 . The device as claimed in claim 2 , wherein the frame comprises a plurality of contact protrusions formed to be in contact with the shutter.

4 . The device as claimed in claim 1 , further comprising a shading member configured to operate in association with the exposure member so as to shield the instant film,
wherein the shading member includes an opaque film having an elastic force and comprises a first shading film and a second shading film respectively connected to a front end and a rear end of the exposure member, and the first shading film and the second shading film are disposed in the housing such that a part of each of the first shading film and the second shading film is configured to be in a rolled state and another part of each of the first shading film and the second shading film is configured to be in an unrolled state.

5 . The device as claimed in claim 1 , wherein the traction unit comprises:
a lever configured to move the exposure member to the pre-exposure position or the post-exposure position; an elastic member configured to elastically support the lever; and a locking member configured to lock or release the lever at the pre-exposure position of the exposure member, wherein the lever is connected to a front end of the exposure member by a first string and connected to a rear end of the exposure member by a second string.

6 . The device as claimed in claim 1 , further comprising:
a damping unit configured to elastically support the exposure member in a direction in which the exposure member moves from the post-exposure position to the pre-exposure position.

7 . The device as claimed in claim 1 , wherein the traction unit further comprises an instant film-setting member configured to introduce a front end of the instant film into the developing agent-spreading member by applying a force to a rear end of the instant film in response to the exposure member moving from the pre-exposure position toward the post-exposure position.

8 . 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 and configured to move along a longitudinal direction of the housing; a pressurizing member provided on one side of the exposure member and configured 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 configured 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.

9 . The device as claimed in claim 8 , further comprising:
a display fixing unit disposed on an upper side of the housing and configured to fix a portable display device to the housing.

10 . The device as claimed in claim 9 , further comprising:
a middle plate disposed between the display fixing unit and the housing and provided with an input window corresponding to at least a portion of a screen of the portable display device, wherein the middle plate is hinge-engaged with the housing and provided with a fixing protrusion configured to fix the instant film to the housing.

11 . The device as claimed in claim 8 , wherein
the exposure member includes:
a lens array;
a lens supporting unit to support the lens array; and
a shading plate fixed to the lens supporting unit and configured to cover the instant film,
the pressurizing member includes at least one pressure roller, and the lens supporting unit includes at least one roller groove in which the at least one pressure roller is rotatably inserted, the at least one roller groove disposed in parallel to the lens array.

12 . The device as claimed in claim 11 , wherein
the moving member comprises a handle disposed on one side of the lens supporting unit of the exposure member, and the shading plate is disposed on another side of the lens supporting unit of the exposure member, and the handle has a length corresponding to a length of the shading plate.

13 . A portable image-forming device, comprising:
a housing; an exposure member configured to expose an instant film disposable in an inside of the housing to a light radiating from a portable display device; a shading member configured to operate in association with the exposure member and configured to shield the instant film; a traction unit connected to the exposure member and configured to move the exposure member to a pre-exposure position; a developing agent-spreading member including a plurality of rollers configured to spread a developing agent provided in the instant film over an exposed portion of the instant film; a driving unit configured to indirectly transmit power to the exposure member through the shading member and to directly transmit power to the developing agent-spreading member; and a battery to supply power to the driving unit.

14 . The device as claimed in claim 13 , wherein
the housing includes an upper housing which includes a plurality of sensors to sense the exposure member at a first position at which the exposure member starts exposure and to sense the exposure member at a second position at which the exposure member completes the exposure, and the exposure member includes a shutter to hide or expose a lens array disposed in the exposure member, the shutter configured to expose the lens array at the first position and to hide the lens array at the second position.

15 . The device as claimed in claim 13 , wherein
the housing includes an upper housing and a lower housing being hinge-engaged with the upper housing and opening or closing a lower side of the upper housing, and the upper housing is provided with at least one sensor to sense whether the lower housing opens or closes the lower side of the upper housing.

16 . A portable image-forming device, comprising:
a housing configured to accommodate an electronic device which displays an image; a traction unit configured to be engaged with the electronic device and to move in a first direction toward a pre-exposure position while the electronic device is inserted into the housing in the first direction; an exposure member configured 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
