Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a light-shielding device for an exposure section built into a printer section of an auto printer, and more particularly to a light-shielding apparatus suitable for a case where a greeting card kit is mounted on the exposure section.

[0002]

2. Description of the Related Art An automatic printer is composed of a printer section, a processor section and the like. In the printer section, a roll of printing paper is continuously fed, and an exposure section exposes an image such as a negative film. Done.

By the way, in recent years, a photo card, in which a photograph is printed on a part of the back side of a postcard or the like, and a greeting text or the like is printed on a margin part, has become widespread. A greeting card kit may be attached to the exposed part of the printer part of the printer for use. As shown in FIG. 6, the greeting card kit 1 has a squirrel plate 2 which can be freely inserted and removed, and a photographic portion exposure window 2a and a character portion exposure window 2b are formed in the squirrel plate 2. The greeting card kit 1 is provided with a band-shaped photographic printing paper 3, and the exposure and the feeding are appropriately performed.

When printing is performed by an auto printer equipped with the greeting card kit 1, a squirrel film 4 on which a greeting or the like is printed is attached to the character portion exposure window 2b of the squirrel plate 2, and the squirrel plate is attached. Insert 2 into the greeting card kit 1 from outside the auto printer. Then, the characters and the like on the lith film 4 are exposed on the photographic printing paper 3, and subsequently, a portion of the photograph is exposed through the exposure window 2a of the photographic portion.

By the way, since the squirrel plate 2 can be inserted into and removed from the greeting card kit 1, external light may enter the inside of the greeting card kit 1 from the outside of the auto printer. Therefore, the light blocking device 5 is attached to the insertion portion of the squirrel plate 2.
Is provided.

The light-shielding device 5 comprises a substantially box-shaped light-shielding frame 6 fixed to the body frame portion 1a of the greeting card kit 1, and an opening 5a is formed at one side of the light-shielding frame 6. Are formed. The opening 5a is exposed to the outside of the auto printer, and the casing of the auto printer and the outer surface of the light shielding frame 6 are appropriately combined,
Light is blocked between these.

As shown in FIG. 7, a support plate 7 having a substantially flat plate shape is provided inside the light-shielding frame 6 so as to face each other. The support plate 7 presses the light-shielding frame 6 with a pressing spring 8. And the supporting plates 7 are urged so as to press each other. A light-shielding cloth 9 is attached to the surface of the support plate 7, and the surface of the light-shielding cloth 9 has fine fur.

In a state where the squirrel plate 2 is not inserted, the support plates 7 are urged to press each other by the pressing springs 8, so that the light shielding cloths 9 attached to the support plates 7 are closely attached to each other. ing. Therefore, even if external light irradiates the opening 5a exposed to the outside of the auto printer, the external light reaches the inside of the greeting card kit 1 by being blocked by the light shielding cloth 9. There is no.

When the squirrel plate 2 is inserted, the squirrel plate 2 is sandwiched between the light shielding cloths 9 and the support plate 7 is biased by the pressing spring 8. , Light shield cloth 9 on both sides of squirrel plate 2
Is pressed against the squirrel plate 2 so that the fur coat of the light-shielding cloth 9 comes into close contact with the squirrel plate 2. Therefore, the external light from the opening 5a is reflected in the greeting card kit 1
Will not penetrate inside.

[0010]

However, in the above-described light-shielding device 5, since the weight of the support plate 7, the pressing spring 8 and the like are large, the weight of the entire device becomes large and the greeting card kit. There is a risk of hindering the reduction in size and weight of item 1. Moreover, the assembling work of the light shielding device 5 is relatively complicated, and there is a possibility that the simplification of the manufacturing work and the reduction of the manufacturing cost may be hindered.

Therefore, an object of the present invention is to provide a light-shielding device for an exposure section of an auto printer, which can reduce the manufacturing cost without increasing the weight.

Further, if the squirrel plate 2 is repeatedly inserted and removed for a long period of time, the fur of the light shielding cloth 9 may remain in a collapsed state, and the light shielding ability may deteriorate.

Therefore, it is another object of the present invention to provide a light-shielding device for an exposure portion of an auto printer, which is capable of sufficiently shielding light even when the hair of the light-shielding cloth is still lying down.

[0014]

In order to achieve the above-mentioned object, a light-shielding device for an exposure unit of an auto printer according to the present invention is an exposure unit for exposing the image of a film on a photographic paper. In a light-shielding device for shielding the insertion portion of an exposure plate that is detachable from the exposure portion, the pressure member includes pressure members that press each other, and the exposure plate slides between the pressure surfaces. Freely, when the exposure plate is not sandwiched between the pressing surfaces, the pressure surfaces press each other to shield light, and when the exposure plate is sandwiched between the pressing surfaces, It is characterized in that the pressing surface presses both side surfaces of the exposure plate to shield light.

Further, it is also characterized in that the pressing member is formed of a foam material, or a light shielding cloth is provided on the pressing surface of the pressing member.

Further, it is characterized in that a convex portion is provided on one side of the pressing surface and a concave portion is provided on the other side, and the convex portion and the concave portion engage with each other to shield light.

[0017]

When the exposure unit is attached to the auto printer, the light shielding device of the exposure unit is exposed to the outside of the auto printer. Then, the casing of the light shielding device and the casing of the auto printer are combined, and light is shielded between these casings.

When the exposure plate is detached, the pressing members press each other and the pressing surfaces are in close contact with each other inside the light shielding device, so that light shielding is performed. Therefore, the light outside the auto printer does not enter the exposure unit through the light blocking device.

Further, a film on which characters and the like are printed is attached to the exposure plate, and the exposure plate is inserted into the exposure unit when a printing operation is performed. At this time, the exposure plate is slid while being sandwiched by the pressing surfaces of the pressing member, and the pressing surfaces press both side surfaces of the exposure plate. As a result, light is shielded, and light outside the auto printer does not enter the exposure section.

Furthermore, when a light-shielding cloth is provided on the pressing surface, the light-shielding ability is improved due to the fine fur coat on the surface of the light-shielding cloth.

When a convex portion is provided on one side of the pressing surface and a concave portion is provided on the other side, the convex portion and the concave portion are engaged with each other,
Since the pressing surface is curved, light can be shielded more reliably.
