Abstract

PURPOSE:To correctly carry photographic paper and to scale down a printer by dislocating the level of a part sandwiched by driving rollers toward the back of the photographic paper and making the level of a guide mechanism related to the driving roller different from that of the width-directional mask member of a paper mask. CONSTITUTION:The level L1 of the part 61C sandwiched by the driving rollers 61A and 61B is displaced toward the back of the photographic paper P from the level L2 of a photographic paper path in a printing area PA, and the level of the guide mechanism 84 relaged to the driving roller 61 is made different from that of the width-directional mask member of the paper mask 80, but in the same direction of the member 83. Consequently, a space for moving said member 83 to the other side can be secured, and moreover the driving roller 61 and the guide mechanism 85 related to the roller 61 can be arranged close to the printing area PA. The photographic paper can thereby be carried correctly, and the printer can be scaled down.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a photographic printing device.

[Background of the invention]

Generally, when forming a photograph, it is necessary to print the image on photographic paper using a photographed and developed negative film, and a photographic printing apparatus is used for this purpose. The photographic paper from this photographic printing device is then developed by a photographic processing device to form a photograph.

FIG. 5 is an explanatory diagram showing the outline of an automatic photo processing system, in which 1 is a photo printing device, 2 is a developing processing section, 3 is a drying section, and 4 is a part of a cutter. A lamp L and a reflecting mirror R are provided, and the optical image of the negative film N formed by the light source lamp L is reflected by the reflecting mirror R, thereby conveying the photographic paper roll from the photographic paper roll storage section 5 and positioning it in the print area. The image of the negative film N is exposed onto the photographic paper P and printed.

The printed photographic paper P is then conveyed through a developing tank 6, a bleach-fixing tank 7, and a stabilizing tank 8 of three types, which constitute the developing section 2, in this order, and is subjected to a developing process. . The photographic paper P that has been developed in this manner is then fed into a drying section 3 and dried, for example, with warm air, and then cut by a cutter portion 4 to form a photograph.
