DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a photosensitive material processing apparatus for developing photographic materials such as photographic film and photographic paper.

[Conventional technology]

In general, photosensitive material processing equipment develops and then dries photographic material that has already been photographed. Fl+ It is desirable to have an elegant process, easy fabrication, and easy cleaning and maintenance.

Automatic processing equipment that processes silver halide photosensitive materials such as photographic film and photographic paper usually has processing tanks for developing, fixing, washing, etc. (the contents, order, number, etc. of the photosensitive materials to be processed) (varies depending on the material) and a drying chamber, in which the photosensitive material is sequentially conveyed through each processing tank by conveyance means such as conveyance rollers, developed with each processing solution, and then transported into a drying chamber and exposed to warm air. After being dried, it is discharged outside the machine.

FIG. 6 shows an example of a photosensitive material processing apparatus such as a photocopying apparatus, which includes an image exposure section 10 at the top, a paper feed section 20 at the upper right, a photosensitive material transport section 30 at the middle, and a development processing section at the bottom. (Photosensitive material processing apparatus) The photosensitive material processing apparatus is comprised of a photosensitive material processing apparatus 40 and a drying section 50 on the right side thereof.

The image exposure section 10 includes a document table glass 11, a light source 12, a first
It consists of a scanning mirror 13, a second scanning mirror 14, a third scanning mirror 15, a lens 16, a fourth fixed mirror 17, and a fifth fixed mirror 18. A rod-shaped halogen lamp is used as the light source 12, and provides uniform exposure without uneven light distribution in the axial direction.

A first scanning unit consisting of a light source 12 and a first scanning mirror 13 moves parallel to the document table glass 11 and illuminates the document. At this time, the exposure width on the platen glass surface is 10 to 1
It is 511JI. A Pt52 scanning unit consisting of a second scanning mirror 14 and a third scanning mirror 15 is mounted on a moving table and moves in the same direction as the first scanning unit and at half the moving speed of the first scanning unit. Also, the first
The scanning unit and the second scanning unit operate in synchronization with the speed at which the conveying section 30 conveys the photosensitive material. The above-mentioned exposure scanning is almost the same as that used in a known electrophotographic copying machine, but the image is reversed by the final fifth mirror 18, and a latent image corresponding to the original image is formed on the photosensitive surface of the photosensitive material. formed directly on the

On the other hand, a photosensitive material such as a silver halide photographic material is formed into a roll and is stored in a magazine 21 . The magazine 21 is removably installed at a predetermined position within the paper feed section 20 of the copying apparatus. Roll-shaped photosensitive material R in magazine 21
is fed into the conveying section 30 through the feeding section 22.

The roll-shaped photosensitive material R inserted into the conveyance section 30 is sandwiched by the rotation of two pairs of feeding rollers 31 and 32, and when it is fed a predetermined length, it is cut by a cutting device 33 into a cut sheet shape. . This sheet-like photosensitive material S is fed again by the feeding roller 32, and is brought into pressure contact with the upper and lower conveying belts 3.
4, and then the direction is changed approximately at right angles to reach an intermediate position ra (imaging position) 37 of the conveying rollers 35, 36.

When the leading edge of the sheet-like photosensitive material S passes the imaging position 37, in response to this, the tjIJ1 scanning unit scans the original image on the document table plus 11 with a predetermined width for exposure, and the second scanning unit also synchronizes. The scanning exposure light flux from these passes through the lens 16 and is reflected by the fourth mirror 17.
,! A latent image is formed on the photosensitive surface of the sheet-like photosensitive material S at the imaging position 37 via the @5 mirror 18 .

The sheet-like photosensitive material S that has been scanned and exposed passes through the achievator section 38, and then passes through the development tank 41, bleach-fix tank 43, first stabilization tank 44, and second stabilization WJ 45 of the development processing section 40. After being dried with hot air in the drying section 50, the completed processed sheet-like photosensitive material S is discharged to the outside of the machine from the discharge port.

The development processing section 40 is provided below the image exposure section 10 and the photosensitive material transport section 30, and each of the processing tanks 41.
43, 44, and 45 are arranged horizontally. Each processing tank is filled with a developing solution CD, a bleach-fixing solution OF, and a washing solution or a stabilizing solution SR. Note that since the developer CD for developing silver halide photographic light-sensitive materials, particularly color light-sensitive materials, is strongly alkaline, each member of the developing tank 41 is made of It 2 -flukaline material.

Inside each processing tank, a gear train consisting of a plurality of gears receives rotational driving force from a drive source, a plurality of roller rows and an idle plate which are rotated by the 111 rows of teeth and convey the sheet-like photosensitive material S, and Each rack member includes a gear train, a roller train, and a frame that supports an idle plate and the like.

When cleaning the processing tank or rack components, inspecting or repairing them, or when the tank is clogged with sheet photosensitive material (jam), pull the rack components out of the processing tank and remove them after the above work is completed. Then, insert the rack member into the processing tank again and set it at a predetermined position.

[Problem that the invention seeks to solve]

In such a photosensitive material processing apparatus, a considerable amount of time is required from when the main switch of the copying apparatus is turned on until copying preparations are completed and copying can be started.

This is the time required to set the processing solution, especially the developer CD, to a predetermined temperature range, for example, 38 to 39 DEG C., and a long warming-up period is required especially when there is a large temperature difference from room temperature.

For this reason, after a series of copying operations has been completed, when there is a waiting time for the next copy, the main switch is often left in the standby state without being turned off to maintain immediate copying capability.

In such photosensitive material processing equipment that is running idle,
A plurality of roller rows in each processing tank of the development processing section and a large number of gear trains that transmit rotational driving force from a drive source to the roller rows are all in a rotating state. The roller train and the gear train agitate the processing liquid in the processing tank, create small waves on the liquid surface, and contact the air surface. In particular, gears rotating at the boundary between the processing liquid level and the space violently ripple the processing liquid level, which accelerates the oxidation of the processing liquid, changes the characteristics of the processing liquid, especially the developer, and reduces the processing capacity. descend. Further, there are also disadvantages such as dust in the air being absorbed into the processing liquid, resulting in a reduction in image quality. Furthermore, since the developing solution and bleach-fixing solution are maintained at a high temperature of 38° to 40°, the amount of dirt generated from the processing solution increases as the liquid surface vibrates, causing damage to components, sensors, etc. inside the copying machine. This often results in corrosion and malfunction or detection failure.

[Means for solving problems]

The present invention aims to improve processing capacity by long-term stabilization of processing liquid characteristics by eliminating such drawbacks in the prior art and preventing deterioration of processing liquids such as developing solutions. Furthermore, it is an object of the present invention to provide a photosensitive material processing apparatus that reduces the scattering of processing liquid and the generation of soot, prevents malfunctions due to malfunctions and detection failures, and prevents the generation of noise in a standby state.

A photosensitive material processing apparatus of the present invention that achieves the above object is a photosensitive material processing apparatus that performs photographic processing by transporting the photosensitive material through the processing apparatus by a transporting means, and the transporting apparatus is stopped after discharging the photosensitive material from the processing apparatus. It is characterized by the fact that it is made to do so.

FIG. 5 is a plan view showing a part of the display panel (display section 77) provided at the top of the copying apparatus.

When the sheet-shaped photosensitive material S sent out from the conveyance roller 39B of the photosensitive material conveyance section 30 is fed into the developer tank 41, the passage of the leading end and the trailing end thereof is detected by the automatic processing machine inlet sensor 64. If the transport is normal, the transport position display mark [IJ771] on the display section 77 is illuminated. If this sensor 64 detects a conveyance failure, the paper jam mark 770 and the mark "1" on the display section 77 will be displayed.
71 is displayed blinking.

The photosensitive material S passed through the sensor 64 and was conveyed through the developer 1WJ42 and the bleach-fix Pa4.
An electric signal is generated by a sensor 65 installed near the squeeze roller RIO above the boundary with the roller RIO. In response to this signal, the mark l"2J772 on the display section 77 is continuously illuminated while the photosensitive material S passes through the sensor 65. If a conveyance failure is detected, the paper jam mark 770 and the Mark l”2J772 blinks.

1 to 69, the presence or absence of a photosensitive material during subsequent conveyance is detected, and it is determined whether or not there is any photosensitive material in the entire conveyance zone. Subsequently, the timer 73 is started, and after a predetermined time of 1 second, for example 10 to 30 seconds, a timer OFF signal is used to drive the conveyance motor of the development processing section 40 and the hot air dryer 53 of the drying section 50 using a stop signal. Make it stop.

Since the hot air dryer 53 blows hot air at 56 to 60° C. during drying, the inside of the drying section 50 remains at a fairly high temperature even after the drive is stopped. A conveyance roller 5 driven by a conveyance motor of the processing section 40

During this time, the inside of the drying section 50 is slowly cooled by the exhaust fan in the main body of the copying machine, and after T seconds have passed, the conveyor belt 52 rotates. Even if it stops, there will be no effect.

By doing this, the rotational drive of the gear train provided in each outer unit of the developing processing 40 is stopped.
The acceleration of oxidation of the processing solution due to idle rotation of the gear near the processing solution level is eliminated, and the storage stability of the processing solution, especially the developer CD, is improved.

In addition, since the processing liquid replenishment circulation system is operating in this standby state, the processing liquid circulation and temperature adjustment in each processing tank continues, and the processing liquid is uniformly stirred and the temperature is controlled. Resumption is possible immediately.

Note that in the above embodiment, the stop control of the development processing section 40 is performed using the signal from the paper discharge sensor, but the present invention is not limited to this, and the process from the signal such as the start of photosensitive paper to the paper discharge is performed. Since the time required for
The conveyance roller of the development processing section 40 may be stopped.
