DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image recording apparatus and an automatic development processing apparatus, and more particularly to an image recording apparatus for exposing a long strip of photosensitive material to form an image when an operator gives an instruction. The present invention relates to an image recording apparatus capable of rapidly cutting a photosensitive material therein, and an automatic development processing apparatus including the image recording apparatus.

[0002]

2. Description of the Related Art In recent years, automatic developing apparatuses utilizing digital exposure have been widely used.

The automatic developing device generally includes an image recording device that forms an image (latent image) by exposing photographic paper, and a processor (developing process) that develops a photosensitive material on which a latent image is formed by the image recording device. Device).

In the image recording apparatus, a negative image on a photographic film is photoelectrically read by an image reading apparatus and converted into image data, and a photosensitive material such as photographic paper is scanned by recording light modulated based on the image data. Exposure to record a latent image. The photographic paper on which the latent image has been formed by the image recording device is developed by the processor and discharged as a print (photograph).

FIG. 12 shows an example of the image recording apparatus.

Is a loading unit 38 in which a magazine 26 containing rolled photographic paper A is mounted, an exposure unit 30 for scanning and exposing the photographic paper A to form a latent image, and a magazine 26 mounted in the loading unit 38. The photographic paper A is pulled out of the photographic paper A and is conveyed toward the exposure unit 30 while punching holes in the photographic paper A to correspond to the position information (so-called frame information) for each print and the number of photographic films. An image position information punching unit 28 for forming image position information such as position information (so-called sort information);
Located on the downstream side of the exposure unit 30, the photographic paper A on which a latent image is formed by the exposure unit 30 by the print head 102 by using the print head 102 to record various photographic information such as the date of photographing the original film, the number of the original film, and the frame number. A printing unit 32 that prints on the back side of the latent image, in other words, a back printing, and a printing paper A that is located downstream of the printing unit 32 and that temporarily stores the exposed and printed photographic paper A and temporarily stores the image recording device 23 and the developing device (see FIG. (Not shown).

A first cutter section 112 is provided between the printing section 32 and the reservoir 34, and a second cutter section 124 is provided downstream of the reservoir 34.
