Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an instant photocopying apparatus for copying manuscripts, original drawings, photographs, and the like.

[Conventional technology] Traditionally, original pictures (here, "original pictures" refer to manuscripts, photographs).

Refers to things that are copied by a copying device, such as original paintings. ) has been done using a camera and a close-up device.

There were also devices that read an image once using a scanner-type image league using COD, etc., and then output the image data using a thermal printer or the like.

[Problem to be Solved] However, in the former case, the settings of the camera, close-up device, lighting, etc. are extremely complicated, and the quality of the copy changes significantly due to the influence of the lighting. Furthermore, the magnification changes depending on the photographing distance, and it is difficult to provide a uniform magnification over the entire surface of the copy due to lens aberrations and the like. Furthermore, the device was large and had poor operability.

In the latter case, a reading section and a printer section are required.
The configuration was complicated and the load on the circuit was large.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide an instant photocopy system which is simple in construction, easy to operate, produces high-quality copies, can be made compact, and does not require elaborate circuitry. The goal is to provide equipment.

[Means for Solving the Problems] In order to achieve the above object, an instant photocopying apparatus according to the present invention includes a photosensitive surface and a mark that forms an inverted image of the image formed on the photosensitive surface as a visible image. an instant photographic photosensitive material having a screen, the photosensitive surface facing parallel to the original image, and an erect real image located between the original image and the photosensitive surface, with a narrow area of the original image on the photosensitive surface; a drive means for moving the optical means parallel to the original image; a light source for illuminating the original image; and a light shielding means for preventing unnecessary light from reaching the photosensitive surface. are doing.

[Example] Hereinafter, an example of the present invention will be described in detail based on the drawings.

First, I will explain the principle. As shown in the IIA diagram, the instant photographic photosensitive material a is arranged parallel to the plane of the original image. An optical means C is provided between the instant photographic photosensitive material a and the original image to form an image of a narrow band-like area of the original image on the instant photographic photosensitive material a, and the optical means C moves the original image by means of a moving means (not shown). It is designed to move parallel to the surface of the screen. A light source C for illuminating the original image is provided between the instant photographic photosensitive material a and the original image. Therefore, when the optical means C is moved, for example, from the left end to the right end, as the optical means C moves, small areas of the original image are successively projected and imaged onto the instant photographic photosensitive material a through the optical means C,
As a result, the original image is copied onto the instant photographic photosensitive material a. d is a light blocking means, which blocks light other than the projection light from the optical means C.

Instant photographic materials applicable to the present invention include:
There are peel-off type and mono-sheet type.

In the case of the peel-off type instant photographic photosensitive material shown in FIG. 1B, assuming that the original image is rFJ, a mirror inversion image of rFJ is formed as a latent image on the photosensitive surface a1 by optical means. This inverted image is further inverted and brought into close contact with the printing surface a2, and a developer is applied to form a visible image that is an inverted latent image.

In addition, in the case of the mono-sheet type instant photographic photosensitive material shown in FIG. An image is formed.

Inside the winding vibrator 27,
A coil spring 31 is connected between the shaft 28 and the shaft 29 in a state in which it is wound a certain amount to apply tension to the light-shielding film 34. The shaft 29 is fixed to the belt pulley 21 via an extension rod 30.

As shown in the second figure, a pair of light-shielding film guides 32, 32 are provided parallel to the carrier 14 and at a wider interval than the opposite sides of the opening 2d, and the light-shielding film 34 has one end connected to the winding vibrator. 27° 27, and the other end is fixed to the carrier 14 via an angle 33.

The light-shielding film 34 is wound around the winding means 26, 26 a predetermined number of times in consideration of the movement range of the carrier 14.

In the attached state, the coil spring 31 applies a counterclockwise rotational force to the winding vibrator 27 on the left side in FIG. 3, and a clockwise rotational force to the right side winding vibrator 27 in FIG.

The light shielding film 34 functions to shield the photosensitive film 9C from light except for the projection portion of the rod lens array 15. Note that when the carrier 14 is in a standby state located at the left end or right end in FIG. 2, the projection portion of the rod lens array 15 is out of the opening 2d, and the entire surface of the photosensitive film 9C is shielded from light by the light shielding film 34.

A copy area indicator 1137 consisting of four lines is attached to the outer surface of the case 2 as shown in the fifth figure.

[Effect] The instant photographic copying apparatus of the present invention forms an image of the original image directly on the photosensitive surface of the instant photographic photosensitive material, which is placed parallel to the original image, using an optical means that moves parallel to the original image. Therefore, compared to the case where the signal is first converted into an electric signal, the structure is extremely simple and does not require a complicated circuit, and can be made into a small and handy type. In addition, when using a close-up device, it is possible to copy easily without the need for complicated adjustments in the installation of the close-up device, and furthermore, the optical means can be moved along the original image to sequentially copy onto the photosensitive surface. Therefore, it is possible to obtain copies with uniform magnification over the entire surface of the instant photographic photosensitive material.
