Scanner

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.

In a sheet feeding device having a forwardly rotating conveying rotary member and a reversely rotating separating rotary member, and for separating and conveying sheets one by one by a sheet separating portion comprised of these two rotary members, the setting of an appropriate center distance when a sheet is separated and conveyed with the center distance between the conveying rotary member and the separating rotary member fixed is effected smoothly within a short time, and a first sheet feeding mode for effecting sheet feeding while automatically adjusting the center distance for each sheet by a center distance changing device and a controller and a second sheet feeding mode for effecting sheet feeding with the center distance fixed can be arbitrarily selected, and when the setting of the center distance during the selection of the second sheet feeding mode is to be effected, the execution of the center distance setting standard operation (adjusting operation) of detecting the center distance automatically adjusted when one or any plurality of sheets are fed in the first sheet feeding mode, and displaying the set value of the center distance based on the result of the detection on a displaying portion is possible.

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 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.

A film carrier includes a roll carrier for supplying and returning a rolled film between a supply reel and a take-up reel to retrieve any frame on the film, and a fiche carrier for holding a sheet film and capable of retrieving any frame on the film. A pedestal portion, including guides, shifts the roll carrier and the fiche carrier in the same plane between respective predetermined retard positions and respective application positions.

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.

Film transport apparatus

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.

Film feeding apparatus

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.
