More particularly, the present invention relates to a photographic processing device capable of easily changing an edge guide width of a rack for guiding a photosensitive material into a plurality of processing layers.

[Conventional technology]

As shown in FIG. 3, the photographic printing / processing apparatus is roughly divided and the color paper 1 is pulled out from the magazine 2 in which the color paper 1 is stored in a roll shape, and the image recorded on the developed negative film or the like. A print unit 3 for printing, a process unit 4 for developing the baked color paper 1, a drying unit 5 for drying the developed paper 1, and cutting the dried paper 1 into predetermined dimensions for each frame. And a cut portion 6.

The processing section 4 is removably suspended in a plurality of processing layers 7a to 7e in which processing solutions for development processing are contained, and in the processing solutions of the processing layers 7a to 7e. Guide racks 8a to 8e for guiding the exposed color paper 1 to
It consists of and.

Each of the guide racks 8a to 8e, as shown in FIG.
A pair of side plates 10a, 10b having locking portions 9a, 9b for locking the both edges of the processing tank when the rack is attached to the processing tank and the side plates 10a, 10b are axially mounted to fix the color paper 1 Guide rollers 11a and 11b that form a loop and guide into the processing tank, a pair of edge guides 12a and 12b that guide both side edges of the color paper 1 between these guide rollers 11a and 11b, and the edge guide 1
A guide width changing means 14 for moving the color papers 2a and 12b in the width direction according to the width of the color paper 1 is provided.

The guide width changing means 14 includes an edge guide width changing dial 15 provided at the upper end of the side plate 10a, a scale device 16 for displaying the edge guide width, a rotating shaft 17 connected to the dial 15, and the side plate 10a. , 10b, and a moving screw rod 20 connected to the rotating shaft 17 via bevel gears 18 and 19, and an edge guide 10.

It is composed of a female screw portion 21 screwed to 0b. The male screw portions 20a and 20b of the moving screw rod 20 have one side opposite to the other side. Therefore, when the dial 15 is rotated and the moving screw rod 20 rotates in one direction, the pair of edge guides 12a and 12b separate from each other via the female screw portion 21, and when rotating in the other direction, the edge guides 12a and 12b approach each other. Thus, the edge guides 12a and 12b can be set to desired widths corresponding to the width of the color paper 1.

[Problems to be Solved by the Invention]

However, in the conventional photo printing / processing device,
A guide width changing unit is provided for each rack, and when the rack is removed from the processing tank for maintenance or the like, the rack may be returned into the processing tank with the width of the edge guide changed. In such a case, when the width of the edge guide of the returned rack is larger than that of the other rack, the color paper cannot be guided to the guide roller, and when the width of the edge guide of the returned rack is large, the color paper cannot be guided at the edge guide position. Will get stuck. Therefore, when returning the rack to the processing tank, the edge guide of the rack to be returned must be set to have the same width as the edge guide width of another rack, which causes a problem that the returning operation becomes complicated. In particular, when a plurality of racks are removed from the processing tank, a returning operation is required for each rack, which is a troublesome problem.

The present invention has been made to solve the above problems, and when the rack is removed from the processing tank during maintenance or the like, these returning operations can be easily performed, and the width of the edge guides can be set at the same time. It is an object of the present invention to provide a photographic processing device that can be used.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the present invention provides each of the guide racks with guide width changing means for moving the edge guide in the width direction according to the width of the photosensitive material. A common rotation shaft is mounted over the shaft, and friction transmission means is interposed between the common circuit shaft and each guide width changing means.

[Action]

When the rack is taken out of the processing tank for maintenance or the like and returned to the processing tank after the maintenance or the like, the common rotating shaft rotates in one direction. The rotational force of the common circuit shaft is transmitted to the guide width changing means of each rack via the friction transmitting means. As a result, the edge guide of each rack is moved to the movement limit. Since the load of the rack whose edge guides have moved to the limit of movement increases, slip occurs between the flange member and the transmission gear, and the same state is maintained. In this way, the edge guides of the racks are sequentially returned to the initial state where the movement limit is reached, and finally the edge guides of the previous racks are set to the initial position and are shared. After this commonization, the common rotation shaft rotates in the direction opposite to that at the time of setting the initial position. This rotational force is transmitted to the guide width changing means via the friction transmitting means, and the edge guide of each rack is changed corresponding to the width of the photosensitive material based on the width signal of the photosensitive material. At this time, the edge guides of the racks are simultaneously moved by the same amount via the common drive shaft, so that the edge guides of the racks are simultaneously set to a desired width.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The same members as those of the conventional photoprinting / processing apparatus shown in FIGS. 3 and 4 are designated by the same reference numerals, and the description thereof will be omitted.

FIG. 1 is a perspective view showing a schematic configuration of rack edge guides 12a and 12b and guide width changing means 30 for moving them. The rack has almost the same structure as the conventional rack shown in FIG. 4, and the difference is that the drive gear 31 is fixed in the middle of the rotating shaft 17. This drive gear
Reference numeral 31 is for obtaining a rotational driving force for moving the edge guides 12a and 12b from a common rotation shaft 32 described later.

On the processing tank side, when the rack is mounted in the processing tank, the processing tank side gear 34 that meshes with the drive gear 31 of the rack.
Is attached. A bevel gear 38 is fixed to the lower shaft end of the processing tank side gear 34. The processing tank side gear 34 will be described in detail later, but the edge guides 12a and 12b
A limit sensor 35 for detecting that the vehicle has returned to the initial position is attached. This limit sensor 35
Is composed of a magnet 53 embedded in the processing tank side gear 34, and a reed switch that is turned on when the magnet 53 approaches.

A common rotation shaft 32 is mounted on the upper part of the processing tank so as to extend between the processing tanks. The common rotation shaft 32 is provided with friction transmission means 40 including a friction mechanism for rotating the rotation shaft 17 of each rack. Specifically, as shown in FIG. 2, the friction transmission means 40 includes a common rotary shaft side flange member 41 attached to the common rotary shaft 32 via a key 33 and a common rotary shaft 32. A common shaft side bevel gear 42 that is movably attached and meshes with the bevel gear 38, a friction member 43 interposed between the bevel gear 42 and the flange member 41, a bevel gear 42 and a flange member.
41 and friction members to connect them with a predetermined friction force.
A spring member 44 made of synthetic rubber or the like that is pressed against 43, a fixing ring 45 for fixing the spring member 44 to the common rotating shaft 32,
A fixed ring 46 for restricting axial movement of the common shaft side bevel gear 42. In addition, reference numerals 47 and 48 in the drawing denote attachment screws for fixing the respective fixing rings 45 and 46 to the common rotating shaft 32.

By changing the position of the fixed ring 45 on the common rotation shaft 32, the friction transmission means 40 adjusts the elastic restoring force of the spring member 44 to change the friction force generated in the friction member 43. Has been Therefore, when the load is simply to move the edge guides 12a and 12b, the flange member 41 and the bevel gear
42 can be rotated integrally, and the edge guide
After 12a and 12b have moved to the movement limit, due to the increased load due to this movement limit, slippage may occur between the friction member 43 and the flange member 41 and the bevel gear 42, and the transmission of the rotational force may be interrupted. it can.

The drive shaft of the motor 50 is connected to the common rotation shaft 32. The motor 50 is controlled by the controller 51.
The controller 51 is configured to rotate the motor 50 forward and backward based on an initial setting signal, a color paper width signal, an edge guide initial state detection signal from the limit sensor 52, and the like.

The width signal of color paper 1 is
Form a contact width code on the surface of the magazine of
This can be obtained by reading this with a contact-type width signal detection device or the like. Instead of this, the operator may directly input by operating the keyboard.

Further, instead of detecting the movement limit of the edge guides 12a, 12b by the limit sensor 52, the motor can be stopped by a timer. In this case, the time is set by a timer so that all the edge guides can return to the initial positions.

Next, the operation of this embodiment will be described. When the rack is removed from the processing tank due to maintenance or the like and then returned, the controller 51 first receives the initial setting signal,
The motor 50 is rotated to rotate the common rotation shaft 32 in one direction.
As a result, the pair of edge guides 12a and 12b of each rack move so as to separate from each other. By this movement, the edge guide 12
When a and 12b have moved to the movement limit and are in the initial position state, slips occur in the friction transmission means 40 in order from the one in the initial position state. Therefore, finally, the edge guides 12a and 12b are in the initial position state for all the racks. The limit sensor 52 of each rack detects the initial position state return of all the racks, and after this detection,
The common rotating shaft 32 rotates in a direction opposite to that at the time of returning to the initial position by a predetermined amount based on the width signal of the color paper 1. Thereby, the edge guides 12a and 12b can be changed all at once in accordance with the width of the color paper 1. Therefore, even when the width of the color paper 1 is changed, this can be easily dealt with.

Although the friction transmission means 40 is attached to the common rotating shaft 32 side in the above embodiment, the present invention is not limited to this, and the friction transmission means 40 includes the bevel gear 38 and the processing tank side gear 34. It can be provided between and.

Further, in the above embodiment, the common rotating shaft 32 is rotated by the motor 50 and the controller 51, but the present invention is not limited to this, and the common rotating shaft may be manually rotated. You may In this case, a handwheel is provided on the common rotation shaft, and it is rotated a predetermined amount in one direction to set the edge guide of each rack to the initial position, and then the handle is turned in the opposite direction to move the edge guide. Set to a predetermined width.
With this configuration, the edge guide of each rack can be changed at the same time according to the width of the color paper with a simple configuration.

〔The invention's effect〕

As described above, according to the present invention, the common rotary shaft is laid across each processing tank, and the rotational force of the common rotary shaft is transmitted to each guide width setting means by the friction transmission means by the friction mechanism. I have to. Therefore, all the racks can be brought to the initial position state by simply rotating the common rotation shaft in one direction. Further, by rotating the common rotating shaft by a predetermined amount corresponding to the width of the photosensitive material, the edge guides of the racks can be easily and simultaneously set to the desired width.
