Problems solved by technology

Therefore, it cannot be used for photosensitive materials that cannot form a ring shape.
[0006] In addition, in this device, several sheets of photosensitive materials cannot be concentrated in one place, so when it is necessary to stay several sheets of photosensitive materials, several actuating mechanisms must be arranged, which will cause the device to be enlarged. not practical

Embodiment 1

[0062] figure 1 It is a schematic diagram showing a photoprinting device. The photographic printing device is composed of a cassette 1a containing a roll-shaped photosensitive material, a printing processing part 2, a developing processing part 3, and a stop supply device 5 provided on the transport path between the printing processing part 2 and the developing processing part 3.

[0063] The supply unit 2e cuts the roll-shaped photosensitive material contained in the cassette 1a into pieces corresponding to printing size and supplies it as a sheet-like photosensitive material 1, and the printing processing unit 2 prints a negative film on the sheet-like photosensitive material 1. The print processing unit 2 is composed of a light source unit 2a, a negative mask 2b, a lens unit 2c, an exposure unit 2d, and the like. The light source unit 2a includes a bulb, a filter, and a diffusion box.

[0064] The developing treatment part 3 carries out the developing treatment to the she...

Embodiment 2

[0086] The structures of the film cassette, printing processing section and developing processing section in the photoprinting device of this embodiment are the same as those in Embodiment 1, and a stop supply device 5 is provided on the transport route between the printing processing section and the developing processing section. Using Figure 7 and Figure 8 construction shown.

[0087] 7 shows an overall view of the stop supply device 5. A pair of conveyor belts 5a, 50a are arranged facing each other to form a conveyance path 5A for conveying a plurality of sheets of photosensitive material 1 by the nip portion of the conveyor belts 5a, 50a.

[0088] The conveyor belts 5a, 50a are hung on the driving rollers 5b, 50b near the printing processing part 2, the driving rollers 5c, 50c near the developing processing part 3, and the conveyance roller 5d arranged between the driving rollers 5b, 50b, 5c, 50c. , 50d, arranged on the fixed rollers 5e, 50e and the movable dancer roller...

Embodiment 3

[0098] The structures of the film cassette, printing processing section and developing processing section in the photoprinting device of this embodiment are the same as those in Embodiment 1, and a stop supply device 5 is provided on the transport route between the printing processing section and the developing processing section. use Figure 9 to Figure 13 construction shown.

[0099]The stop supply device 5 is composed of a stop mechanism 6 that holds the printed photosensitive material 1 while transporting and stops, a transport mechanism 7 that transports the sheet photosensitive material 1 into the stop mechanism 6, takes out the sheet photosensitive material 1 from the stop mechanism 6, and The supply mechanism 8 and the supply auxiliary mechanism 9 that supply the developing processing section 3 constitute ( Figure 9 ).

[0100] The stop mechanism 6 is composed of oppositely arranged conveyor belts, a straight first conveyor belt 61 is arranged on one side, and an L-...

Abstract

The invention provides a photoprinting device which can gather several sheet-shaped photosensitive materials in one place without bending them into a ring shape. There is a stop and supply device in the process of transporting the printed sheet-shaped photosensitive material from the printing processing section to the developing processing section. Temporarily stop several sheets, and according to the processing status of the developing processing part, the printing-finished sheet-shaped photosensitive materials that are staying are sequentially supplied to the developing processing part. The number of remaining sheets of the printed sheet-like photosensitive material can be adjusted corresponding to the number of printed sheet-like photosensitive materials exceeding the development processing capacity. The number of staying sheets is set according to the relationship between the time during which printing processing is interrupted due to replacement of negative film in the printing processing section and the developing processing capacity of the developing processing section.

Description

technical field [0001] The present invention relates to a photoprinting device, in particular to a device for automatically supplying a printed sheet photosensitive material to a developing processing unit after temporarily stopping it. Background technique [0002] The photoprinting device has the characteristics of intermittently processing photosensitive materials in the printing processing section and continuously processing photosensitive materials in the developing processing section. The intermittent processing of the printing processing section also includes the replacement of negative films. [0003] Therefore, even if the printing process is completed in the printing processing section, the printing process of one photosensitive material cannot be performed when the developing process in the developing processing section is not completed. In addition, the negative film replacement operation cannot be performed in the printing processing section. Development process...
