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 includes a lamp, a CCD array, an image density adjustor, first and second shutter drivers, first and second shutters, an image area discriminating circuit, and a microcomputer. The lamp illuminates an image and retrieval information of a microfilm having the image and the retrieval information at the side of the image. The CCD array receives light from the image and the retrieval information on the microfilm illuminated by the lamp. The image density adjustor, first and second shutter drivers, and first and second shutters cooperate with each other to record the image of the microfilm on a recording medium. The image area discriminating circuit discriminates the image from the retrieval information according to an output from the CCD array. The microcomputer controls the image density adjustor and the first and second shutter drivers so as not to record the retrieval information on the recording medium according to an output from the image area discriminating circuit.

Image recording apparatus for recording only the image area of a film

There is disclosed an image forming apparatus capable of image formation under optimum image forming conditions in response to the detected image density. The image forming apparatus has image forming unit for forming an image corresponding to an original on a recording material, detector for detecting the image density of the original, and controller for controlling the operable condition of said image forming unit to regulate the copy density in response to the image density detected by said detector said controller includes memory storing control data for the operable condition of said image forming unit in response to the detected image density, and is adapted to make an access to said memory in response to the detection signal of said detector and to control said operable condition according to control data obtained by said access.

Microfilm reader-printer

Disclosed is a reader-printer capable of being changed over between a reader mode in which the light image of an original is projected onto a screen and a printer mode in which the light image of the original is projected onto a photosensitive medium. The reader-printer has first optical means for forming a first optical path for projecting the light image onto the screen and second optical means for forming a second optical path for projecting the light image onto the photosensitive medium. The second optical means includes a first mirror and a second mirror. The first mirror is movable so that it is positioned outside the first optical path during the reader mode and is positioned in the first optical path during the printer mode. The second mirror is movable with the first mirror. When the first mirror is being moved between a first position and a second position, the light from the original is detected by light detecting means, and when the first mirror is positioned in the first optical path, the light image is reflected by the first mirror and then reflected and guided to the photosensitive medium by the second mirror.

Reader-printer

This invention provides an apparatus for reproducing image from a microfilm, in which a microfilm having a negative or positive image is illuminated by illuminating image and projecting thus illuminated microfilm image onto a photosensitive member. The reproducing apparatus is provided with a charger for positively or negatively charging the surface of the photosensitive member, measuring device for measuring the light intensity from thus illuminated microfilm, and charge controller for selecting the polarity of charge to be given to the photosensitive member in response to the result of measurement by the measuring device thereby providing a positive reproduced image regardless whether the image on the microfilm is negative or positive. In another embodiment the apparatus is provided with development controller for selecting toner for image development on the photosensitive member in response to the result of measurement by the measuring device.
