[Problems to be solved by the device]

However, in the above-described conventional auxiliary printing apparatus, the lamp 2 is arranged above the case 1 and the light of the lamp 2 is directly applied to the printing paper 10 to perform printing, so that the printing paper 10 is printed. Since the amount of light to be emitted differs between the portion directly below the lamp 2 and the portion deviated from the lamp 2, it is not possible to uniformly irradiate the photographic paper 10 with light, and the printing due to the variation in the amount of light is caused. There is a problem that uniform printing cannot be performed due to variations in density and the like.

The distance between the lamp 2 and the photographic printing paper 10 is usually about 70 to 100 mm.
There is a demand for a small auxiliary baking device with a size of about m.
If the distance between the lamp 2 and the photographic printing paper 10 is shortened in this way, the above-mentioned variation in the amount of light appears more markedly, and uniform printing cannot be performed.

The present invention has been made in view of the above-mentioned points, and provides an auxiliary printing apparatus capable of performing uniform printing without variation in light amount even in a small apparatus and without variation in density and color unevenness. The purpose is to

For example, the lamps 2 that form a tubular light source that is formed by continuously arranging a plurality of tungsten lamps 2 are arranged,
Between these lamps 2, a transparent light guide plate 13 made of acrylic or the like is arranged so that the light emitted from the lamp 2 enters from both ends thereof. Further, on both end faces of the light guide plate 13, first diffuser plates 13A and 13B each having a substantially hemispherical concavo-convex surface facing each lamp 2 so as to obtain more uniform light are fixed. . On the upper surface of the light guide plate 13, there is formed a hairline surface 14 which is formed by the concavo-convex pattern made up of a large number of fine lines, and on the lower surface of the light guide plate 13, the second diffusion plate 15 is closely arranged. It is set up.

Further, below the light guide plate 13, in the present embodiment, two third diffusion plates 16, 16 are arranged in parallel with the light guide plate 13 with a predetermined interval. This diffuser
As shown in FIG. 2, a light-shielding portion 17 may be formed on the 16 by black silk printing so that the light from the light guide plate 13 is diffused more uniformly, and the light amount may be adjusted. .

Below the case 1, a crimping plate 5 attached to a supporting plate 3 via a support column 4 is disposed so as to be able to move up and down. The crimping plate 5 is attached to the supporting column 4 by a coil spring 6 Is urged downward by the urging force of. Further, a solenoid 7 having a plunger 8 extending in the vicinity of the lower surface of the crimping plate 5 is attached to the support plate 3, and by operating the solenoid 7 to project the plunger 8 upward, The crimping plate 5 is moved upward against the biasing force of the coil spring 6.

Further, a message board 9 on which a predetermined message is formed is detachably mounted on the upper surface side of the crimping plate 5, and further, the crimping plate 5 and the message board 5 are provided at both lower ends of the case 1. 9 and the specified photographic paper 10
A sheet insertion port 11 for inserting a sheet and a sheet ejection port 12 for ejecting the printing paper 10 after printing are formed.

Next, the operation of this embodiment having the above-described configuration will be described.

First, the message board 9 in which predetermined characters and the like are formed in white is mounted below the case 1, and the photographic printing paper 10 on which a predetermined photograph or the like is printed is inserted from the paper insertion port 11. When the photographic paper 10 is conveyed between the message board 9 and the crimping plate 5, the conveyance of the photographic paper 10 is stopped and the solenoid 7 is turned on to cause the plunger 8 to project. As a result, the crimping plate 5 is raised against the biasing force of the coil spring 6, and the photographic printing paper 10 is crimped to the message board 9.

In this state, by turning on the lamp 2 for a predetermined time, the characters and the like on the message board 9 are printed.
Bake again. At this time, the light emitted from each of the lamps 2 is diffused through the diffusing plate 13A, and then enters the inside of the light guide plate 13 from both end faces of the light guide plate 13. The light is reflected by the hairline surface 14 of the light plate 13 so as to be further diffused, and is emitted from the lower surface of the light guide plate 13 through the diffusion plate 15 in a surface emission state. Further, the light emitted downward from the light guide plate 13 is transmitted to each of the diffusion plates 16
As a result, the photographic printing paper 10 is further uniformly diffused, and the photographic printing paper 10 is irradiated from the lower surface of the diffusion plate 16.

When the baking is completed, the solenoid 7 is turned off.
By setting to F, the plunger 8 is sucked downward, the pressure plate 5 is lowered by the urging force of the coil spring 6, and the photographic printing paper 10 after printing is discharged from the paper discharge port 12 to the outside of the case 1. It is discharged, then developed, fixed, dried and then discharged.

As described above, according to the present embodiment, even a small-sized device having a short distance between the lamp 2 and the photographic paper 10 due to the surface emission by the light guide plate 13 and the uniform light diffusion effect by the diffusion plate 16. Further, it is possible to perform uniform light irradiation on the photographic printing paper 10 without variations in light amount, and it is possible to perform uniform printing without variations in printing density and color unevenness.

Further, by forming the light shielding portion 17 at a predetermined position of the diffusion plate 16, it is possible to perform more uniform light irradiation.

It should be noted that the present invention is not limited to the above-described embodiments, but can be variously modified as necessary.

As described above, the auxiliary baking device according to the present invention is
The light emitted from the two tubular light sources is diffused by the first diffusion plate and then introduced into the light guide plate located between the two tubular light sources, and the light from the message board side surface of the light guide plate is evenly distributed through the second diffusion plate. Since the surface emission is performed on the photographic paper and the surface-emitted light is passed through the third diffusion plate to make the surface illuminate more uniformly, the photographic paper is irradiated, so that the distance between the lamp and the photographic paper is short. Even with a small device, it is possible to perform uniform light irradiation on the printing paper without variations in the amount of light, and to perform uniform printing without variations in printing density and color unevenness. Further, by disposing a diffusion plate between the light guide plate and the printing paper, the light emitted from the surface of the light guide plate can be diffused more uniformly, so that the printing paper can be printed more uniformly.
