DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image recording operation control device capable of holding an optical image obtained by a photographing lens as a visible image and reading the visible image.

[0002]

2. Description of the Related Art Conventionally, silver halide photographic materials have been widely used as materials for recording optical images. Silver halide photographic materials have features such as high light sensitivity and resolution, and are also economical, but not only are the development processes complicated,
There is also a disadvantage that a visible image cannot be obtained simultaneously with shooting. Although a dry development method has been developed to simplify the development processing, it is impossible to immediately develop the image, that is, obtain a visible image at the time of photographing, even with this development method.

On the other hand, as a non-silver salt photographic material, an electrophotographic material, a diazo photographic material, a free radical photographic material and the like are known. However, none of these photographic materials has characteristics such as silver halide photographic materials and can be developed immediately. Since electrophotographic materials can be dry-developed and an electrostatic latent image obtained by exposure can be immediately developed with toner or the like, they have been widely used mainly in copiers.

In recent years, in such an electrophotographic technique, a photographic material, such as a silver halide photographic material, in which a recording medium itself is directly electronically developed and the developed visible image is immediately obtained, has been developed. Is coming. Such an electronically developed recording medium is referred to as an electro-developing recording medium in this specification.

For example, JP-A-5-2280 discloses a recording medium in which an electrostatic information recording medium and a charge holding medium are combined. The electrostatic information recording medium comprises a photoconductive layer and an inorganic oxide layer. And the charge holding medium has a liquid crystal display element. With this configuration, when the electrostatic information recording medium is exposed while a voltage is applied to the electrostatic information recording medium and the charge holding medium, charges corresponding to the amount of incident light are generated on the electrostatic information recording medium. Since the strength of the electric field applied to the liquid crystal display element arranged opposite to the electrostatic information recording medium changes according to the generated charges, an image corresponding to the light amount distribution is displayed on the liquid crystal display element, that is, the image is developed. .

Japanese Patent Application Laid-Open No. 5-150251 discloses a dispersion type liquid crystal display element in which an image displayed on the liquid crystal display element is retained even when an electric field applied to the liquid crystal display element is removed.

[0007]

When an image developed on such a liquid crystal display element is detected by a line sensor or the like, a light source is provided on one side of the liquid crystal display element, and the other side of the liquid crystal display element is provided on the other side. A line sensor is disposed in the scanner, and light transmitted by the light source is read by the line sensor via a scanner optical system. That is, the light source is arranged on the optical axis of the scanner optical system. However, if the light source is located at a position close to the electro-developing recording medium during the shooting operation, vignetting occurs,
There is a possibility that the exposure amount in the electro-developing recording medium becomes insufficient.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an image recording operation control device capable of always performing proper exposure on a recording medium without causing vignetting during a photographing operation.
