Abstract

PURPOSE:To obviate the spoiling of photographed films by operating a warning means and stopping development after the developing state is maintained for the period of the time required for the final exposed image to complete the development processing when detection signals are detected after driving of a cutter. CONSTITUTION:The warning means 31 is operated and the development is stopped after the developing state is maintained for the period of the time required for the final exposed image to complete the development processing 16 when the detection signals are detected from detecting means P1, P2 after driving of the cutter 14. A signal for an exchange of the cutter or the like is, therefore, emitting even in the case of the outbreak of such a trouble that the film fails to be cut by the wear or corrosion of the cutter blade. The operator is able to make the development processing without spoiling the films photographed thus far and the wasteful consumption of the films is prevented in this way.

Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention is an image recording device that sequentially photographs image information such as a subject on a long film and develops the photographed film, and in particular, an image recording device that has a built-in film cutter and can be used as desired. This is applied to an image recording device that can cut and develop the film into lengths.

<Prior Art> Conventionally, a processor camera is known as a typical example of this type of image recording device. FIG. 5 shows an example of a film transport system of such a processor camera.

In the figure, an O-roll-shaped film F wound around a supply reel 3 supported by a supply shaft 2 of a film supply chamber 1 passes through a supply roller 4 along a film transport path, and then passes through a guide roller of an imaging section 5. 6.1 It is sent into the buffer section 10 by the capstan roller 9 via the roller 7. That is, in the photographing section 5, an image of a subject (not shown) is continuously slit-exposed by the photographing lens 8 in synchronization with the film F on the photographing section roller 7, which is to be photographed.

The film F photographed in the photographing section 5 is temporarily stored in the bath sofa section 10 before being transferred to the next developing process, and this stored film F is sent out again to the developing section 16. The buffer section 10 is configured to store photographed film F in a loop shape,
Inside it is a film guide 0-ra 11. Buffer section 1
A transport roller 12 for feeding the film F from 0 to the developing section 16. - Film detection sensor 13 for detecting the film F along the film transport path. A cutter 14 and a cutter guide 15 are provided for cutting the photographed film into a desired length.

Washing tanks 19 and 20 each having a water-washing tank 20c are provided, and the photographed film F is automatically transported sequentially through each processing liquid tank, and after being subjected to development, fixing, and washing, it is transferred to transport rollers 21a, Drying chamber 21 with 21b
The developing process is completed by drying with hot air inside the winding chamber 2.
A take-up reel 24 supported by a take-up shaft 23 in 2
is wound up. Then, the rear end of the film F cut by the cutter 14 passes through the film detection sensor 25,
After it is detected that the developed film F has been completely wound up on the take-up reel 24, the developing motor (not shown) stops, and the development is completed.

<Problems to be Solved by the Invention> Incidentally, in recent years, with regard to films as photosensitive materials used in image recording devices (processor cameras) as described above, films with excellent durability and strength due to improvements in their base materials have been increasingly used. There is.

Therefore, if the blade of the film cutter installed inside the device to cut the long film into the desired length according to the amount of shooting becomes worn out and its sharpness deteriorates, the film cannot be cut. There was a problem. In addition, the film cutter blade in particular has the disadvantage of being easily corroded by the strong alkaline developing solution in the developing area.
The above-mentioned problem may occur.

For the above-mentioned reasons, when the film is not cut at the time of film cutting, in the conventional apparatus, the film is constantly transported in the developing section, so there is a problem that the developing state does not end forever.

Further, in such a case, since unexploited film is naturally wasted, it is desirable to detect the trouble by some kind of detection means and immediately stop the apparatus (in the developing state).

However, if the device, that is, the transport of the film is stopped, the processing of the film that has been shot will also be stopped midway, resulting in a problem that the images on the film that have been shot will be damaged.

SUMMARY OF THE INVENTION In view of the problems of the prior art described above, it is an object of the present invention to provide an image recording apparatus that can develop film that has already been photographed without damaging it even if there is an accident in the cutter section.

<Means for Solving the Problems> In order to achieve the above-mentioned object, there is provided a photographing section that photographs a subject on a long film, a developing section that develops the photographed film, and a system between the photographing section and the developing section. A film buffer section provided, a conveying roller for conveying the long film from the buffer section to the developing section, a cutter for cutting the long film provided downstream of the conveying roller, and a cutter driving means. The image recording apparatus is provided with a detection means for detecting the rotation of the conveyance roller and a warning means activated in response to a predetermined detection signal of the detection means, and after the cutter is driven by the cutter drive means, the detection means detects the rotation of the conveyance roller. When a detection signal is detected, a warning means is activated, and the final exposed image on the long film in the series of photographs of the subject is maintained in the developed state for a time necessary to complete the development process, and then developed. It was designed to stop.

The image recording device configured as described above determines that the film has not been cut (film cut error) if the detection means detects rotation of the transport roller even after the film cutter has been activated during development. A warning means issues a warning, and a timer means maintains the developing state until the final image on the film at the end of photographing completes development processing, and then stops development, thereby preventing unnecessary waste of film.

<Example> Hereinafter, an example of the present invention will be described based on FIGS. 1 to 4.

FIG. 1 is a schematic configuration diagram of an image recording device (processor camera), and the same components as those of the conventional example shown in FIG.

The figure shows a buffer section 101. : Shows a state in which the processed film F is stored in a loop, and after a series of shooting is completed, when development starts, the conveying roller 12 is driven to send the film F in the buffer section 10 to the developing section 16. It has become.

In the same figure, an encoder 9b is provided on the shaft 9a of the capstan roller 9, a photointerrupter 9C is provided opposite to the encoder 9b, and furthermore, the capstan roller 9 is provided on the shaft 9a. A capstan roller drive motor 9e for driving at a constant speed and an electromagnetic clutch 9d for transmitting (on) and releasing (off) the drive as necessary are provided. Similarly, conveyance roller 1
An encoder 12b is provided on the second shaft 12a, and a photointerrupter 12c is provided opposite the encoder 12b. Furthermore, an electromagnetic clutch 12d and a drive pulley 12e are provided on the shaft 12a. Further, a drive pulley 1 provided on the output shaft of the developing unit drive motor 16a
A conveyance roller drive belt 16G that transmits the driving force to the drive pulley 12e and a developing unit drive belt 16d that transmits the driving force to the rollers of the developing unit 16 are hung on the belt 6b.

Next, FIG. 3 shows the drive mechanism of the film cutter 14.

In the figure, reference numeral 14a denotes a cutter arm that holds the cutter 14, and is rotatably supported by a shaft 14b on a stationary member (not shown) and biased counterclockwise in the drawing by a lever spring 14C. 14d is a solenoid, and one end of the cutter arm 14a is pivotally supported by a pin 14f on the plunger 14e, and when the plunger 14e is attracted by its excitation, the cutter arm 14a is rotated by a spring 14c around the shaft 14b.
It oscillates against the urging force of. And cutter guide 15
guides the cutter 14 from both sides and holds the film F during cutter operation.

FIG. 4 shows a control block diagram for operating the image recording apparatus configured as described above.

In the figure, signals are inputted to a control circuit 30 such as a CPU from pulse detectors P1 and P2 of a film detection sensor 13.25, a capstan roller 9, and a transport roller 12, respectively, and these input signals and a control circuit 30 of a CPU 30 are inputted to a control circuit 30 such as a CPU. Capstan roller drive motor 9e based on the data signal of the memory section.

Electromagnetic clutch 9d and developing section drive motor 16a.

A control signal is outputted to the electromagnetic clutch 12 and a solenoid 14d for driving the film cutter, and a warning control signal is outputted to the warning means 31.

In this embodiment with the above configuration, at the start of development, the development drive motor 16a operates, and each conveyance roller in the development section 16 is driven via the drive pulley 16b and the development section drive belt 16d.

, drive pulley 16b, conveyance roller drive belt 16C
The conveying roller 12 is rotationally driven by turning on the electromagnetic clutch 12d via the drive pulley 12e,
Film F is transported to developing section 16. When the transport roller 512 is driven, the amount of film transport is detected by counting and detecting the number of pulses proportional to the amount of rotation of the transport roller 12 using the encoder 12b and the photointerrupter 12c.

As a result, when the film feed amount reaches a predetermined amount (in this embodiment, after the film is sent to the developing section 16, the film feed amount is 2.
0cIi), the electromagnetic clutch 12d is turned off to release the drive of the transport row 512. after that,
The film F is transported only by the driving of the transport roller in the developing section 16, and the transport roller 12 is driven to rotate by the film F being transported.

Next, when all of the film F stored in the buffer section 10 is conveyed to the developing section 16, the capstan roller 9 is brought into a stopped state (the electromagnetic clutch 9d is in the off position I) as the film F is conveyed. A pulse signal is generated from an encoder 9b connected to the shaft 9a.By this pulse signal, the final exposed image of the film F at the exposure position E on the photographing section roller 7 is sent to the position where it passes the cutter 14. After that, the solenoid 14d is activated and the cutter 1
4, the film F is cut.

Once the film F is cut, the cutter 14 in FIG.
The transport roller 512 located on the upstream side stops being rotated by the film F, but in the unlikely event that the film F is not cut due to wear or corrosion of the blade of the cutter 14, the transport roller 12 will continue to rotate by the accompanying rotation. Continue to do so. Therefore, after the solenoid 14d is activated, the encoder 12b provided on the shaft 12a of the conveyance roller 12 and the photointerrupter 1
2c detects a pulse signal for a certain period of time or longer, that is, the CPLI 30 detects a pulse signal by the conveyance roller pulse detector P2.
If the pulse signal is input for a certain period of time or longer, it is determined that there is a film cut error (the film F has not been cut), and a control signal is output to the warning means 31 such as a buzzer indicator lamp, and the warning means 31 is activated. The operator is alerted when activated. Also, after the pulse signal is detected by the timer in the CPLJ 30, the time fit (
After maintaining the developing state for about 90 seconds in this embodiment, the l1lII] signal is output to the developing unit drive motor 16a to stop the motor 16a and stop the development.

In the above-mentioned embodiment, the rotation of the roller accompanying the film at the time of a film cutting error after the cutter operation was detected by the encoder 12b provided on the conveying row 512, but the encoder 12b is located upstream of the position of the cutter 14. For example, capstan roller 9. The film guide roller 11 degree may be controlled by encoders provided on the photographing section roller 7, guide roller 6, and feeding roller 4, or may be effected by an encoder provided on the supply shaft 2.

Furthermore, in the above embodiment, when a film cutting error occurred after the cutter was activated, development was stopped after waiting approximately 90 seconds. Any number of seconds may be sufficient as long as the time required for the exposed image to complete the development process.

<Effects of the Invention> As explained above, the present invention prevents wear of the cutter blade by providing a detection means for detecting the rotation of the conveyance roller and a warning means activated in response to a predetermined detection signal from the detection means. Even in the unlikely event that a problem occurs such as the cutter not being able to cut when the cutter is activated due to corrosion, the warning means will notify the operator, giving a signal to replace the cutter blade, etc. It is possible to develop the photographed film without damaging it, and after that, by stopping the apparatus, there is an effect that the film can be prevented from being wasted.
