摘要:
An image reading apparatus capable of increasing the detection accuracy of the size of an original and eliminating the need for an image sensor dedicated to detection of the size of an original. A first reading unit has a first light source disposed on one side of a conveyance path of an original for emitting light to one surface of the original. A second reading unit has a second light source disposed on the other side of the conveyance path for emitting light to be received by the first reading unit, an optical opening for causing the light emitted from the second light source and subsequently received by the first reading unit to pass therethrough toward the first reading unit. The original is detected on the basis of the resultant output of the first reading unit upon receipt of the light emitted from the second light source.

A sheet feeding apparatus has a pair of feeding roller and separating roller an inter-shaft distance changing mechanism for the pair of rollers, and sheet detecting means, and a sheet fed is rammed against the surface on which the feeding roller and the separating roller overlap each other to thereby correct skew feeding, and the feeding roller and the separating roller are moved away from each other to thereby feed the sheet. When the passage of the fed sheet between the feeding roller and the separating roller is detected the feeding roller and the separating roller assume a state in which sheet feeding is impossible. By the above-described operation being performed for each sheet, the correction of skew feeding and the separation of a sheet are effected by the feeding roller and the separating roller.

An image processing apparatus which feeds a placed original, reads image information on the original by a reading unit, and forms an image on the original by an ink-jet printing head arranged on a downstream side along the original feed direction has an add-on processing part for changing the image information read by the reading unit in correspondence with the image to be formed by the ink-jet printing head.

A film feeding apparatus which feeds a film wound on a supply reel to a take-up means and rewinds the film on the supply reel, comprising: a driving shaft for removably receiving and holding the supply reel on which the film is wound and for rotating the reel; a driving means for rotating the driving shaft in a normal or reverse direction; a judging means for judging a rewinding direction of the film wound on the reel held by the driving shaft; and a control means for controlling the driving means to change a rotational direction of the driving shaft in response to the rewinding direction judged by the judging means, when the film is rewound.

An image recording apparatus which projects an image of an image carrier to a screen and records the projected image to a recording medium comprises projection means for projecting an index on the screen, displacing means for displacing the index along the screen, and control means for controlling an image area to be recorded on the recording medium in accordance with a position of the index on the screen.

A film transport apparatus comprises a rotary member for abutting against a rolled film wound on a reel held on a cartridge to drive the film forwardly, a separating device arranged upstream of the rotary member with respect to a direction of rotation of the film for separating a leading end of the film, and a pressing device arranged downstream of the rotary member with respect to the direction of rotation of the film for abutting against the rolled film to press the film.
