An imaging section of an image reading apparatus is mainly constituted of an image forming lens unit, a lens barrel, a holder plate and a CCD area scan sensor. The image forming lens unit is held in the lens barrel that is mounted to a bottom side of the holder plate. The CCD area scan sensor is mounted on a top side of the holder plate. Piezoelectric elements are mounted on the holder plate, for moving the imaging section in two directions that are orthogonal to each other, and 45 degrees to film lengthwise and widthwise directions respectively. For the pixel shift, the image forming lens unit is moved together with the CCD area scan sensor, so the required accuracy of movement is not so strict.

An image reading apparatus includes a diffusion box unit comprising a plurality of diffusion boxes, which each correspond to different sizes of photographic films, and controls the unit in such a manner that the diffusion box, which corresponds to the size of a film whose image is to be read, is positioned on an optical axis of a light source. Accordingly, the responsibility imposed upon an operator can be reduced and the error of choosing a wrong diffusion box can be prevented.

Without using a zoom lens, an image reading device in which image data of an image whose magnification has been changed can be obtained appropriately is provided at a low price. This image recording device moves and adjusts variable focal length lenses, on the one hand, and a photographic element (66), on the other hand, relative to one another, and separately. Accordingly, an original image whose magnification is changed by using variable focal length lenses is formed on the photographing element (66) by moving and adjusting the variable focal length lenses and the photographic element (66) integrally. As a result, image data can be read.

A photographic printer is loaded with two webs of photographic paper, and produces photographic prints by exposure thereto. Initially, the photographic paper is advanced from two photographic paper rolls in parallel. Those two are combined together to constitute a photographic paper roll unit. The photographic paper is cut to obtain photographic paper sheets, on which an image frame is formed. In one embodiment, the photographic paper roll unit includes a single axial core which extends through axial holes of the two photographic paper rolls positioned at an interval L1, and is fitted thereon. The photographic paper rolls include a spliced region for splicing two consecutive photographic paper strips to one another. The spliced region is detected from a single one of the two photographic paper rolls in combination.

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. While the paper sheet is being switched back at the branching section, another paper sheet may be fed into the paper feed path for recording another image thereon through the single image recording section.

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.

A CCD scanner is provided with a regulating circuit, which stores electric-current set values of LED elements of respective colors. The regulating circuit also stores desired values corresponding to optimum light amounts of the LED elements of the respective colors. By utilizing the electric-current set value and the desired value, binary search is performed for the LED elements every color. During the binary search, the light amount of the LED element is regulated, and an electric-current value thereof is determined so as to obtain the optimum light amount. By using the determined electric-current value, the LED element is turned on to read an image.

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.

A photographic printer carries paper sheets in two rows. A skew correcting unit is disposed at a passage of the paper sheets. The skew correcting unit comprises a pre-resist roller pair, a resist roller pair, carrying guides, and pressing mechanisms for moving the carrying guides in an approaching direction to the paper sheet and in a separating direction there from. When correcting the skew of the paper sheet, the pressing mechanism is actuated to move the carrying guide toward a deflection portion of the deflected paper sheet. In virtue of this, an anterior end of the paper sheet is pressed against the resist roller pair. Even if the paper sheet has stiffness, the skew thereof is quickly and accurately corrected.

A photo digitizer records image data of an image frame. In the photo digitizer, a DVD recorder writes the image data to a DVD medium for respectively image frames obtained by reading from photo film. The DVD recorder writes information of piece number of plural film pieces to the DVD at addresses where the image frames are associated with respectively one of the film pieces. The film pieces constitute the photo film. Furthermore, a display panel displays image frames of photo film. A controller reads image data of the image frames from a DVD, and reads information of piece number of a film piece from the DVD. The display panel is controlled to arrange the image frames per the film piece.
