Abstract

PURPOSE:To copy an original picture beautifully irrelevantly to whether the original picture is transmissive or nontransmissive by irradiating the top surface of the original picture with light when the original picture is nontransmissive and irradiating the reverse surface of the original picture with the light when the original picture is transmissive. CONSTITUTION:When the original picture 18 is nontransmissive, a fluorescent tube 68 is turned on and the then the top surface of the original picture 18 is irradiated partially through a transparent plate 24 below a rod lens array 52. The reflected light from the original picture 18 is made incident on the rod lens array 52, part to part, as a carrier 48 moves, so that a latent image is formed on a photosensitive film 40c. When the original picture 18 is transmissive, on the other hand, a fluorescent tube 98 is turned on and then the reverse surface of the original picture 18 is irradiated through a light guide plate 100 and a transparent plate 92. Then the transmitted light from the original picture 18 is made incident on the rod lens array 52, part to part, as the carrier 48 moves to form a latent image on the photosensitive film 40c. Consequently, the original picture is copied beautifully irrelevantly to whether the original picture is transmissive or nontransmissive.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an instant photocopying apparatus for copying original images such as manuscripts and photographs.

[Prior Art] As a copying device for copying original images such as manuscripts and photographs, the present applicant has proposed an instant type copying device that has a photosensitive surface and a printing surface that forms a visible image as an inverted image of the image formed on the photosensitive surface. Instant photographic copying apparatuses using photosensitive materials have been proposed (Japanese Patent Application No. 1-331617, Japanese Patent Application No. 1-331618, and Japanese Patent Application No. 1-333628).

According to this device, an optical means is placed facing the surface of the original image and forms an image of a narrow area of the original image as an erect real image on the photosensitive surface of an instant photographic photosensitive material facing parallel to the original image. The copying apparatus moves the original image sequentially onto the photosensitive surface of an instant photographic photosensitive material, and has the following advantages compared to other copying apparatuses. In other words, since the original image is directly imaged onto the photosensitive surface of the instant photosensitive material using optical means, it requires a more complex circuit than a copying device that reads the image using a scanner-type image reader or the like and outputs the image data using a thermal printer or the like. The configuration is extremely simple, and can be made into a small/X-hand type. Also, compared to the case of copying using a close-up device, complicated adjustments etc. are not required and copying can be performed easily. Furthermore, since the original image is sequentially imaged by moving the optical means, copies with uniform magnification can be obtained.

[Problems to be Solved by the Invention] However, in this device, the surface of the original image is irradiated with light, and the reflected light is imaged on the photosensitive surface of the instant photographic photosensitive material by optical means. However, there was a problem in that it was not possible to make clear copies of transparent original images such as positive film.

SUMMARY OF THE INVENTION An object of the present invention is to provide an instant photocopying apparatus that can neatly copy an original image regardless of whether it is transparent or non-transparent.

[Means for Solving the Problems] In order to achieve the above object, the instant photocopying device according to the present invention includes a main body of the device disposed facing the front surface of the original painting, and a main body disposed facing the back surface of the original painting. The main body of the device includes a backlight device and a backlight device.
An instant photographic photosensitive material has a photosensitive surface and a printing surface that forms a visible image as an inverted image of the image formed on the photosensitive surface, and the photosensitive surface faces parallel to the original image, and the original image and the photosensitive surface are an optical means located therebetween for imaging a narrow area of the original image as an erect real image on the photosensitive surface of the instant photographic photosensitive material;
a driving means for moving the optical means parallel to the original image; a first illumination means for irradiating light onto the surface of the original image when the original image is a non-transparent original image; and a photosensitive surface of the instant photographic photosensitive material. The backlight device is provided with a light shielding means for preventing unnecessary light from entering the backlight device, and the backlight device is provided with a second illumination means for irradiating light onto the back side of the original image when the original image is a transparent original image. The configuration was as follows.

[Function] In the present invention having the above configuration, the main body of the device is disposed facing the front surface of the original picture, and the backlight device is disposed facing the back surface of the original picture, and when copying the original picture, the instant photosensitive material is illuminated by the light shielding means. While preventing unnecessary light from entering the photosensitive surface, the optical means is moved parallel to the original image to sequentially image the original image on the photosensitive surface of the instant photographic photosensitive material, thereby copying the original image.

Here, when the original image is a non-transparent original image, the surface of the original image is irradiated with light by the first illumination means, and the reflected light is imaged on the photosensitive surface of the instant photographic photosensitive material by the optical means.

On the other hand, when the original image is a transparent original image, the second illumination means illuminates the back side of the original image, and the transmitted light is imaged on the photosensitive surface of the instant photographic photosensitive material by the optical means.

Therefore, regardless of whether the original image is non-transparent or transparent, it can be beautifully copied.

On the other hand, inside the case 20, as shown in FIGS. 2 and 3, a pair of guide shafts 46 are provided on both sides in parallel with the bottom plate 20a of the case 20. Carrier 48 is the attachment. Both guide shafts 46 pass through holes and U-shaped grooves (see FIG. 3) provided at both ends of the carrier 48, and the carrier 48 is guided by the guide shafts 46 and can move parallel to the bottom plate 20a of the case 20. It becomes. Therefore, the carrier 48 can move parallel to the original image 18.

A long groove 50 is formed in the center of the carrier 48.
A rod lens array 52 constituting optical means is held within this long groove 50. The rod lens array 52 is capable of forming an erect, same-size image of a strip-shaped area of the original image 18 on the photosensitive film 40c of the instant film 40. Note that, as the rod lens array 52, for example, there is a self-consideration lens array (trade name).

A portion of an endless timing belt 58 is fixed to the carrier 48 at the left end in FIG. 3 with a mounting screw 56 via a mounting bracket 54. As shown in FIG. The timing belt 58 is wound around a belt pulley 62 that is pivotally supported by a bearing 60 (shown in FIG. 2), which will be described later. The belt pulley 62 is configured to rotate in conjunction with the rotation of a drive motor 66, which is a drive means and is fixed to the case 20 via a gear train 64. Therefore, by rotating the drive motor 66 in forward and reverse directions, the carrier 48 can be moved back and forth. Note that a limit switch (not shown) is provided on the movement path of the carrier 48 to restrict the movement range of the carrier 48.

Furthermore, a fluorescent tube 68 constituting the first illumination means is attached to the carrier 48.

A slit-shaped aperture (not shown) is provided on the outer periphery of the fluorescent tube 68 to face the downwardly facing portion of the rod lens array 52, so as to increase the illuminance of a small area of the original image 18 to be copied. It is set.

Further, inside the case 20, bearings 60 are provided at the upper and lower parts of the left and right side parts in FIG. It is supported by a shaft.

To explain in detail, a shaft 76 is attached to one end of the winding vibrator 74.
is firmly fixed thereto, and a shaft 78 is rotatably loosely fitted to the other end of the winding vibrator 74. The shaft 78 is fixed to the belt pulley 62 via an extension rod 82. One end of the light-shielding film 70 is fixed to the winding vibrator 74, 74, and the other end of the light-shielding film 70 is fixed to the carrier 48 via an angle 86, and is parallel to the carrier 48 and extends through the opening 26. The middle portion of the light-shielding film 70 is wound around a pair of light-shielding film guides 84, 84 provided at a wider interval than the opposing sides of the light-shielding film 70. The light-shielding film 70 is wound around the winding vibrator 74, 74 a predetermined number of times in consideration of the movement range of the carrier 48. Inside the take-up vibrator 74, a coil spring 80 is connected between a shaft 76 and a shaft 78 in a state in which it is wound tightly by a certain amount in order to apply tension to the light-shielding film 70. That is,
The coil springs 80 bias the winding vibrators 74 on both the left and right sides in FIG. 2 in opposite rotational directions, thereby applying tension to the light-shielding film 70.

As a result, the light-shielding film 70 shields the photosensitive film 40C of the instant film 40 except for the projection portion of the rod lens array 52.

Note that when the carrier 48 is in a standby state located at the left end or right end in FIG. 1, the projection portion of the rod lens array 52 is removed from the opening 26, and the entire surface of the photosensitive film 40c is shielded from light by the light shielding film 70.

(Configuration of the backlight device 14) The backlight device 14 is provided with a box-shaped case 88 as shown in FIG. Opposite hinge 16
One end of the is attached.

The case 88 has a window hole 90 formed in the upper plate 88a. A transparent plate 92 is fixed to the window hole 90, and the original picture 18 is placed on this transparent plate 92. The transparent plate 92 is made of transparent glass, transparent acrylic resin, or the like, and is capable of transmitting light. This transparent plate 92 is arranged so that an unreasonable load is not applied to the original image 18 by recessing it slightly from the -1- plane of the ``1'' plate 88a on the side where the hinge is attached.

In this case 88, the hinge 16 is attached to the end opposite to the side, and the magnet 92 is attached to the upper plate 88a. The magnet 92 attracts an iron piece 94 attached to the lower surface of the bottom plate 20a of the case 20 of the device main body 12,
It is used to fix the device main body 12.

Inside the case 88, a fluorescent tube 98 constituting a second illumination means is provided, and a light guide plate 100 that emits light from the fluorescent tube 98 is provided. The fluorescent tube 98 is connected to a power source (not shown) provided inside the case 88, and is turned on by operating a switch (not shown) different from the switch of the fluorescent tube 68 of the device main body 12. In addition, around the fluorescent tube 98, there is a fluorescent tube 98.
A light shielding plate 101 covering a part of the light guide plate 8 is provided to prevent the light from the fluorescent tube 98 from leaking to areas other than the light guide plate 100.

The light guide plate 100 faces the transparent plate 92 and is configured to emit surface light directly below the transparent plate 92. This light guide plate 100 has minute irregularities 102 formed on the surface facing the transparent plate 92, so that surface light is emitted with uniform illuminance. Further, on the outer periphery of the light guide plate 100, a reflective film 104 is formed by vapor deposition or plating on a portion other than the portion where light enters from the fluorescent tube 98 and the portion facing the transparent plate 92. The reflective film 104 reflects the unevenness 102 of the light incident from the fluorescent tube 98.
This is to prevent leakage from other sources and increase lighting efficiency.

Next, the operation will be explained.

When the original image 18 is non-transparent, the fluorescent tube 68
The fluorescent tube 68 is turned on by operating a switch (not shown). Then, the surface of the original image 18 is partially illuminated through the transparent plate 24 at the lower part of the rod lens array 52. Next, a start switch (not shown) is operated to start the drive motor 66. Then, the carrier 48 moves toward the right, for example, from the standby position at the left end in FIG. The reflected light enters the rod lens array 52 and forms an image on the photosensitive film 40c, forming a latent image. At this time, as the carrier 48 moves, the light shielding film 70 is pulled out from the left winding means 72, and the light shielding film 70 is wound up by the right winding means 72, and the light shielding film 70 removes unnecessary material from the photosensitive film 40C. The incidence of light is reliably prevented. Then, the carrier 48 reaches the right end position and the photosensitive film 40c of the instant film 40
When the latent image is formed on the entire surface of the carrier 48, the limit switch is activated and the carrier 48 is stopped.

Thereafter, when the tongue piece 40a of the instant film 40 is pulled out, the developer 40d is applied between the printing film 40b and the photosensitive film 40c, and development is completed in about one minute, for example. This results in a beautiful copy.

On the other hand, when the original image 18 is transparent, a switch (not shown) of the fluorescent tube 98 is operated to turn on the fluorescent tube 98. Then, the original image 18 is illuminated from the back side through the light guide plate 100 and the transparent plate 92. Next, when a start switch (not shown) is operated to start the drive motor 66, the carrier 48 moves in the same manner as when the original image 18 is non-transparent. Then, as the carrier 48 moves, transmitted light from the original image 18 successively enters the rod lens array 52 and forms an image on the photosensitive film 40c, forming a latent image. As a result, when the tongue piece 40a of the instant film 40 is pulled out after the carrier 48 is stopped, a beautiful copy can be obtained in the same way as when the original image 18 is non-transparent.
