Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to an image forming apparatus using a photosensitive recording medium.

[Prior Art] Conventionally, this type of device has not been equipped with a mechanism to determine the manufacturing date of the photosensitive recording sheet, and after the photosensitive recording sheet is stored in the device, the user has to check the quality guarantee period. It was not possible to determine.

[Problem 8 to be solved by the invention] However, even after the quality has deteriorated over time and the performance no longer meets the requirements for image formation, the user is unable to discern this and continues to use the device. The use of this apparatus has the disadvantage that, in addition to the photosensitive recording sheet, necessary image forming media such as developer paper are wasted.

The present invention has been made to solve the above-mentioned problems, and aims to make users aware of the deterioration in the quality of photosensitive recording sheets and to eliminate wasteful use of image forming media such as color developer paper. .

[Means for Solving the Problems] In order to achieve this object, the image forming apparatus of the present invention includes a reading means for reading the date of manufacture of the photosensitive recording sheet. It also includes surface water means for displaying data read by the reading means. Furthermore, when the photosensitive recording sheet exceeds the quality guarantee period, a means for automatically stopping the exposure mechanism of the apparatus is provided.

[Function] According to the present invention having the above-described configuration, it is possible to avoid erroneous exposure and wasteful use of image forming media such as developer paper using a photosensitive recording sheet whose performance has fallen short of the performance required for image formation due to aging. There's nothing to do.

[Example] Hereinafter, in order to explain the present invention more specifically, an example will be given and explained.

FIG. 2 is a schematic cross-sectional view of a photosensitive and pressure-sensitive copying machine that is capable of full-color copying and incorporates the winding device of the present invention. The photosensitive paper (consisting of microcapsule paper and color developer paper) that enables such copying is disclosed in Japanese Patent Application Laid-Open No. 58-8873.
This has been proposed in Publication No. 9, etc., and will not be described in detail here.

As shown in the figure, the photosensitive and pressure-sensitive copying machine 40 is composed of an original platen glass 2 and an original platen cover 1, the top plate of which is movable in the horizontal direction.A desired current copy is placed face down on the original platen glass 2. Can be placed in any condition. A light source consisting of a halogen lamp 3 extending in a direction perpendicular to the moving direction of the document table glass 2 and a semi-cylindrical reflecting mirror 4 arranged to surround it is fixed to the upper right side of the copying machine 40. Light is irradiated in a line toward the document table glass 2.

Therefore, the light emitted from the halogen lamp 3 can sequentially illuminate the entire surface of the document table glass 2 from the left end to the right end by moving the document table glass 2 in the left-right direction. The light emitted from the light source passes through the transparent original platen glass 2 and is reflected by the original placed on it. A document table cover 1 is provided to cover the document table.

In addition, in order to use the light emitted from the halogen lamp 3 to irradiate the original with high efficiency, a beam full color 5 is placed to the left of the light source to reflect the light that does not go directly to the original and use it again to irradiate the original. .
