The splice portion (joining means) 6 has a function of joining the trailing end of the leading film 2A and the leading end of the trailing film 2B, which are all pulled out from the cartridge 1.

The patrone 1 rotates the spool 1A in the feeding direction opposite to the winding direction of the film 2 so that the leading end of the film 2 comes out of the film entrance / exit 1b of the patrone body 1a. It also has Therefore, the film accommodating chamber 1g of the cartridge body 1a is formed to have a size substantially the same as or slightly larger than the maximum winding diameter of the film 2 when the film 2 is entirely wound around the spool 1A.

As shown in FIG. 2, the cue function unit 1B is provided with a cartridge holder 15 and a spool rotary shaft 1c, and the motor M rotates the spool rotary shaft 1c via a torque limiter 1d. The shift portion 1e moves the spool rotation shaft 1c in the axial direction to move the engagement end portion 1 of the spool 1A.
It is to be displaced to an engaging position for engaging with f and a position retracted from this.

The Patrone 1 thus constructed
When the spool 1A is rotated in the supply direction opposite to the winding direction of the film 2, the front end of the film 2 is exposed to the outside from the film entrance / exit 1b of the cartridge main body 1a. This eliminates the need for the operator to perform the work of projecting the tongue of the film.

The cutting means 8 is composed of a pair of upper and lower cutters 8a, and the cutter 8a cuts the leading end and the trailing end of the film 2 based on a film start signal, a film end signal and the like. The film start signal and the film end signal are detected from the start mark and end mark recorded on the film 2 in advance.

The film leader 3 guides the film 2 to each processing tank and develops it. The film leader 3 is formed of a flexible thin plate made of synthetic resin, and extends along the center line of the film 2 in the feeding direction. A plurality of feed holes 3a are provided at predetermined intervals (FIGS. 3 to 6). At the rear end of the film leader 3, two films 2 of the cartridge 1 are joined by a splice tape T. Leader set section 3
The film leader 3 loaded in A is pulled out by the pull-out roller pair 10, and then sent to the splice section 6 by the leader feed roller pair 7 and set in the splice section 6.

When all of the film have been pulled out, the rear end of the film 2 is cut by the cutter 8a based on the film end signal to separate the film 2 from the cartridge 1 (FIG. 2). When the trailing end cut portion of the film 2 is located at the splice portion 6, the transfer is stopped. Further, the film 2 is provided with a well-known film reservoir which is temporarily stored when the loop guide 13 is opened, so that the film development is not interrupted by the joining processing time.

(9) When the film 2 is separated from the cartridge 1, the cartridge holder 15 is opened, the cartridge 1 is naturally dropped and discharged into the cartridge recovery box 11, and when the cartridge holder 15 returns to the original position, the cartridge 16 is released. Then, the next cartridge 1 is supplied to the cartridge holder 15 by natural fall.

(10) The trailing film 2B (second film) of the next cartridge 1 is also cued in the same manner as described above, the leading end of the trailing film 2B is cut by the cutter 8a, and then the film 2B is cut. The leading end of the sheet is nipped by the pair of pull-out rollers 5, transferred to the splice section 6, and set on the splice section 6.

(11) Next, in the splice portion 6, the trailing end of the preceding film 2A (first film) and the leading end of the following film 2B (second film) are butted and joined by the splice tape T. (Fig. 5).

(12) By repeating the above operation, the third, fourth, ... Films 2 are also joined one after another and lengthened (FIG. 6).

(13) The thus lengthened films 2A, 2B, 2C ... Are successively developed in the developing section 4.

(14) After the development processing, the film leader 3 joined to the preceding film 2A is separated by a separating means (not shown), and a plurality of films 2A,
2B, 2C, ... Are wound on a take-up reel (not shown) while being joined. Therefore, it is possible to omit the work of separating the developed films 2 one by one from the film reader 3 and the work of joining the separated developed films 2 to each other. (15) Films 2A, 2 wound on a take-up reel
B, 2C, ... Are set in a preprocessor (not shown) and printed.

Embodiment 2 In Embodiment 1, a photographic film cartridge having a film cueing function is used, but in this embodiment, the most popular 35 mm type photographic film cartridge is used.

FIG. 7 shows a film processor. Since the film processor has the same structure as that of the film processor of the first embodiment in principle, the same symbols are given to the drawings and the description thereof is omitted. However, the film processor of the present embodiment employs a type in which the cover 12 is opened instead of the cartridge 16 and the cartridge 1 is set in the cartridge holder 15, and on the back surface side of the cover 12, the upper roller of the drawing roller pair 5 is adopted. 5 is attached via a compression spring 17.

The cartridge 1 is replaced by the cartridge holder 1.
When setting to 5, set the tip of the film 2
It is pulled out from the cartridge 1 in advance using a tongue ejector (not shown) or the like. Then, the cover 12 is opened, the leading edge of the film 2 is inserted into the guide 18, and the cartridge 1
Is set in the cartridge holder 15. Next, cover 1
When 6 is closed, the leading end of the film 2 is pressed and transferred by the pair of drawing rollers 5.

Thereafter, in the same manner as in Example 1, the trailing end of the leading film 2A and the leading end of the trailing film 2B were joined to develop the film 2 in a lengthy state, and then the film 2 was wound on a take-up reel. Taken.

[0031]

As is apparent from the above description, according to the printer processor of the present invention, a plurality of films are sequentially combined and sent in a lengthened state to the development processing section for development processing. Therefore, after the development processing, if the film leader joined to the preceding film is cut off, a plurality of films can be wound at once and the processing efficiency can be improved. Further, since the film is separated from the cartridge by cutting the rear end of the film by the cutting means, the bondability between the films by the splice tape is improved. Further, it is not necessary to manually join the film and the leader.
