Description

Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a photographic printing device. [Background of the Invention] Generally, in forming a photograph, a negative film that has been photographed and developed is used to print the image. It is necessary to print the image on photographic paper, and the Photo Print i device 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. 6 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 causing the negative film N to be transferred to the photographic paper P from the photographic paper roll storage section 5. The image is exposed and printed.

This printed photographic paper P is then conveyed to pass through a development processing tank 6, a bleach-fixing processing tank 7, and a stabilization processing tank 8 of three types, which constitute the development processing section 2 of the photographic processing apparatus, in this order. Development processing is performed. The photographic paper P that has been developed in this way is then sent to a dryer B3 and dried by, for example, hot air.
is cut to form a photograph.

[Problem to be Solved by the Invention 3] In the photo printing device of the automatic photo processing system as described above, the photographic paper roll storage section 5 stores photographic paper rolls with different width dimensions depending on the size of the photograph to be formed. Therefore, it is required that the photographic paper magazine containing the photographic paper rolls be easily replaced. However, replacing the photographic paper magazine is not an easy task because the photographic paper magazine is quite heavy.

In addition, in order to efficiently form a large number of photographs, it is advantageous to automatically transport a long piece of photographic paper using a photographic paper conveyance mechanism and to continuously print on successive portions of the photographic paper. However, in order to achieve this, it is necessary to attach a photographic paper magazine containing the required photographic paper roll, pull out the leading edge of the photographic paper from the photographic paper magazine, and then move it beyond the printing area. Preparation work is required to mount and set the photographic paper in a photographic paper transport mechanism for transporting the photographic paper along an extending photographic paper path.

In this way, attach the leading edge of the photographic paper to the photographic paper transport mechanism.
Mounting is usually done manually, but this is a cumbersome and time-consuming task.

For this reason, there is a need for a photographic printing device in which the leading end of the photographic paper can be easily mounted on the photographic paper transport mechanism when a photographic paper magazine is attached to the photographic printing device. Nothing satisfying is provided.

[Purpose of the invention]

Based on the above-mentioned circumstances, the present invention makes it easy to replace photographic paper magazines, and when a required photographic paper magazine is installed, the leading edge of the photographic paper is automatically pulled out and transferred to the photographic paper transport mechanism. It is an object of the present invention to provide a photographic printing apparatus which can be mounted and therefore very easily prepared.

[Means for solving problems]

The photographic printing apparatus of the present invention includes a magazine mounting mechanism that receives a photographic paper magazine containing a photographic paper roll in the axial direction of the photographic paper roll, and a photographic paper magazine that is mounted on the magazine mounting mechanism. a photographic paper drawer mechanism for pulling out the photographic paper magazine, the photographic paper drawer mechanism comprising a pair of drawer rollers that can be switched between a pressure contact position in which they are pressed against each other and an open position in which they are separated from each other; is mounted on the magazine mounting mechanism, so that the leading end of the photographic paper protruding from the photographic paper magazine is positioned in the gap between the pair of pull-out rollers in the open position.

〔effect〕

With this configuration, the photographic paper magazine in which the photographic paper roll is stored can be exchanged very easily, and the required photographic paper roll can be easily set. Sometimes it is simultaneously achieved that the leading edge of the photographic paper is located in the gap between the pull-out rollers of the paper pull-out mechanism which is in the open position, so that this can be achieved simply by switching the pull-out rollers to the pressure position. By driving, the leading end of the photographic paper can be automatically pulled out from the photographic paper magazine and loaded onto the photographic paper transport mechanism, thus making preparation work extremely easy.
