Abstract: A printer-processor is provided with a paper feed path that is constituted of a plural number of pairs of conveyer rollers, and a feedback path that branches off the paper feed path to feed a sheet of recording paper back to an upstream position of the paper feed path that is placed before an image recording section. For both-side printing, the paper sheet is first conveyed in a forward direction through the image recording section, to record an image on one side. After being conveyed further in the forward direction along the paper feed path to go past a branching section to the feedback path, the paper sheet is conveyed backward into the feedback path. Thus, the conveying direction through the image recording section is unchanged regardless of which side of the paper sheet is served for the image recording.

Abstract: A movable guide is switchable between a guide position for regulating a flexure of a cut paper, and a release position for allowing the flexure of the cut paper. The movable guide is disposed between an exposure feed-roller pair and a guiding/carrying roller pair, which is switchable between a nip state for nipping the cut paper and a release state for releasing the nip thereof. When an anterior end of the cut paper reaches the guiding/carrying roller pair during image recording, this roller pair is changed from the release state to the nip state. A speed of the cut paper carried by the guiding/carrying roller pair is reduced. After that, rotation of the guiding/carrying roller pair is accelerated to carry the cut paper.

Abstract: In an image scanner, an optical image is formed on a CCD image sensor through a lens unit from rays traveling through a picture frame placed in a film carrier, so image signals are picked up from the picture frame. The image signals are corrected with shading correction data that are read out from a memory in accordance with the magnification of the lens unit. The memory previously stores shading correction data for frequently used magnification steps. Shading correction data for less frequently used magnification are previously stored in a hard disc. If the lens unit is set at a magnification for which the memory does not store suitable shading correction data, the suitable shading correction data are read out from the hard disc, and written on the memory.

Abstract: A negative film setter has film holders for having set therein films to be fed. Each of the film holders has both a detecting sensor for detecting whether a film is set therein and a lamp which is lit when a film is set in a film holder and which is not lit when a film is not set therein. Therefore, a user can determine at a glance whether or not films are set in the film holders, thus allowing the user to skillfully set a plurality of films at film setting sections. Accordingly, due to detection by the detecting sensor, the negative film setter can recognize in which film holder a film is set, and films can be fed in a sequential order.

Abstract: An area CCD scanner (image reader) comprises an LED unit (light source), an area CCD and an image-forming lens. The LED unit includes a large number of light emitting elements of each color of blue, green, red and infrared. Light emitted from the LED unit and having passed through a photographic film is received by the area CCD and is converted into an electric signal, which is outputted as photographic image data. When the light source is inspected, a focal point of the image-forming lens is adjusted to a light emitting surface of the LED unit. Then, the LED unit is turned on without setting the photographic film to receive the light thereof with the area CCD. On the basis of the obtained electric signal, a light-emission state of the LED unit is shown on a display.
