Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an image recording apparatus that exposes an image onto a long film and develops the film.

In an image recording device such as a processor camera, it is necessary to carry out processing after development while maintaining a substantially constant film feeding speed to prevent processing unevenness from occurring on the film.

On the other hand, exposure work is usually performed intermittently, sometimes with interruptions for quite a long time, so the film is sent intermittently from the recording section where exposure is performed to the processing section after development, and the exposure interruption time is long. This means that the film advance will be interrupted for a long time.

In order to adjust for the difference in film feeding characteristics between the recording section and the processing section, it has been proposed to provide a storage chamber between the recording section and the processing section and store recorded film in this storage chamber. It is being

However, in such a processor camera, the film in the storage chamber is continuously sent to the processing section, so if the amount of film stored in the storage chamber is small or if exposure work is interrupted for a long time, the film may not be stored. Since the amount of film in the storage chamber decreases and the amount of film in the storage chamber reaches its minimum limit, it is necessary to cut the film in such a case.

For this reason, one unit of related information was recorded separately on separate films, which required editing work later.

If the film is not to be cut, it is sufficient to simply feed the film in the recording section, but this has the disadvantage that the film is wasted.

The present invention provides an image recording device that eliminates the drawbacks of the conventional devices as described above.

In the present invention, the developing method is not limited to the embodiments, and any known developing method can be applied.

The present invention will be explained below using specific examples shown in the drawings.

The film exposed in the photographing section is fed to a storage chamber by a supply roller 51, and the film stored in the storage chamber is fed to a part of the processor by a discharge roller 52.

A film loop door is formed in the storage chamber 1 due to the difference in film feeding speed between the supply roller 51 and the discharge roller 52.

The supply roller 51 is connected to the same drive source as the capstan roller 35 and the feed roller 3T, and these rollers 35, 3
Feed the film at the same speed as in step 7.

As shown in FIG. 3, the pair of supply rollers 51 have a diameter larger at the ends than at the center, and the film F is held between the large diameter portions of the coupling rollers 51.

Further, a gear 63 is fixed to the shaft 52a, and this gear 63 meshes with a gear 64.

The shaft of the gear 64 is drivingly coupled via a second electromagnetic clutch 65 to a second drive shaft 66 , which is coupled to a drive source (motor) of the processor part 2 .

When the first electromagnetic clutch 60 is turned on, the shaft 52a and the first drive shaft 61 are drivingly connected, and the ejection roller 52 is driven by the roller 35.
．． The film is fed at substantially the same speed as 37 and 51.

On the other hand, when the second electromagnetic clutch 65 is turned on, the shaft 52a and the second drive shaft 66 are drivingly coupled, and the ejection roller 52 feeds the film at substantially the same speed as the processor section 2.

When the first and second electromagnetic clutches 60, 65 are respectively off, the discharge roller 52 is not driven and is at rest.

In the above embodiment, the film feeding speed by the rollers 35, 37, and 51 is set to be faster than the film feeding speed of a portion of the processor.

The present invention is not limited to the above embodiment, and the feeding speed of both processors may be the same, or the feeding speed of a portion of the processor may be faster.

Returning to FIG. 1, 70 is a film detector, which is composed of an infrared lamp and an infrared detection light-receiving element, and is turned on when a film is detected and outputs a "1" signal.

is a set output terminal, and Q is a reset output terminal.

Next, the operation of the above-mentioned processor camera will be explained.

First, before starting photography, the microfilm F is passed between the capstan roller 35 and the pinch roller 36, and the film is set in such a state that the leading edge of the film is sandwiched between a pair of feed rollers 37.

It is assumed that the mode selection switch 111 is switched to a mode in which contact a is connected, and the document addition switch 115 is switched to add a document.

Next, when the power switch 120 is turned on by manual operation, power is supplied to the entire apparatus, the lamp 22 is turned on, and the developer is heated.

Further, the clip-flop F6 is set by the ON signal of the power switch, and thereby the 1 drive source of the processor part 2 is driven via the processor 1 drive circuit 121.

Further, each counter and each flip-flop are reset by a reset signal from the initial state setting circuit 116.

After the developer reaches a predetermined temperature, when a large number of originals 5 are put into the container 6 of the automatic original feeder, the original detector 10 is turned on, and the ON signal of the original detector turns on the AND gate G2.
opens, the solenoid 8 is driven via the solenoid drive circuit 110, and one document 5 is supplied to the photographing section 15.

When the document feed detector 25 in the photographing department detects this document,
The document feed rollers 16 and 19 are driven by the document detection signal from the document feed detector.

Further, the document detection signal from this detector opens the shutter 31 via the shutter drive circuit 100, and the capstan roller 35, feed roller 37, and supply roller 51 rotate via the film drive circuit 101, and the film F is fed. Ru.

Therefore, the film F is fed in synchronization with the feeding of the original 5,
The image of the original is projected onto the film and exposed.

Furthermore, the flip-flop F1 is set by the document detection signal from the document feed detector 25.

Further, the document detection signal from the document feed detector 25 is input to the AND gate G1 via the OR gate G20.

At this time, since there is no film at the film detection position of the film detector 70, the AND gate G1 is opened, and the output signal of the AND gate G1 turns on the first electromagnetic clutch 60, causing the discharge roller 52 to rotate.

Therefore, like the rollers 35, 37 and 51, the discharge roller 52 rotates in conjunction with the recording operation of the photographing section.

On the other hand, the drive source for the processor part 2 is the power switch 1200.
The flip-flop F60 set side output' signal set by the ON operation is driven by 1 through the processor drive circuit 121, and the roller 84 of a part of the processor is thereby driven.
, 85, drums 90, 91, 92 rotate continuously.

The originals 5 are sent to the photographing unit 15 one after another by the automatic original feeder 3.
and are sequentially recorded on film.

As the shooting progresses, the leading edge of the film fed by the feed roller 37 advances, passes through the cutter 45, is captured by the feed roller 51, is then sent to the storage chamber by the feed roller 51, and is guided by the film guide member 53 in the storage chamber. After traveling along the line, it is caught by the discharge roller 52 and discharged out of the storage chamber by the discharge roller 52.

When the leading edge of the film reaches the film detector 70, the film detector is turned on, and as the film detector is turned on, the output of the inverter v3 becomes "0", so the AND gate G1 is closed and the first electromagnetic clutch 60 is turned off. , and the discharge roller 52 stops.

Therefore, since the supply roller 51 and the discharge roller 52 are driven in conjunction with the recording operation of the photographing section, even if the leading edge of the film is caught by the discharge roller and the amount of film in the storage chamber 50 is at its lowest limit, This prevents the film located upstream of the discharge roller from being stretched and damaged, and the film from slipping between the discharge roller and the film and causing damage to the film.

Furthermore, since the ejecting roller rotates in conjunction with the recording operation, the film in the photographing section is not unnecessarily drawn out by the driving force of the ejecting roller.

On the other hand, when the film detector 70 is turned on, the supply roller 5
The AND gate G4 opens every time the first pulse generator 55, which is interlocked with the rotation of the first
The counter 105 adds and counts.

Thereafter, as the shooting progresses, since the discharge roller 52 is stopped, a loop of film is formed in the storage 50, the amount of film in the storage chamber increases, and the count value of the first counter 105 increases accordingly.

FIG. 5 shows the change in the amount of film in the storage chamber over time, and is at time t.

indicates the time point when the leading edge of the film is detected by the film detector 70, and time t indicates the time point when the leading edge of the film is detected by the film detector 70.

Thereafter, the amount of film in the storage chamber increases.

At time t1, when the amount of film stored in the storage chamber reaches the first set amount A', a "1" signal is output from the output terminal A of the first counter 105, and this signal activates the alarm 106 and also activates the flip-flop. F2 is set.

Therefore, the user is notified by the buzzer of the alarm 106 or the like that a large amount of film is stored in the storage chamber.

By setting flip-flop F2, or gate G2
1, the second electromagnetic clutch 65 is turned on, and the discharge roller 52 is drivingly coupled to the drive source of the processor part 2.

Therefore, the skewer roller 52 feeds the film in the storage chamber to the processor part 2 at the same speed as the roller of the processor part 2.

A pulse is generated from the second pulse generator 102 in conjunction with the rotation of the discharge roller 52.

At this time, since the film detector 70 is in the on state, the second
The pulses of the pulse generator pass through the AND gate G5 to the first
It is sent to the counter 105 and subtracted and counted by the first counter.

The film taken out from the storage room is developed, fixed, washed and dried in the processor part 2, and then delivered to a tray 86.

If the shooting operation is continued after this, the amount of film discharged from the storage chamber is smaller than the amount of film supplied to the storage chamber, so at time t2, the amount of film in the storage chamber is larger than the first set amount A'. 2 set amount B' (if the amount of film in the storage chamber exceeds this, problems such as damaging the film will occur), a "1" signal is output from the output terminal B of the first counter 105, and this signal causes the flip-flop F3 is set.

AND gate G2 by setting flip-flop F3
is closed and the solenoid 8 is turned off via the solenoid drive circuit 110, thereby stopping the supply of the original 5 and prohibiting the photographing operation.

After this ban on photography, the amount of film in the storage room gradually decreased.
At time t5, when the first set amount N is reached again, a "1" signal is output from the output terminal A of the first counter 105. This signal resets the flip-flop F3, which opens the AND gate G2, and the document is read again. supply has begun, and filming operations have resumed.

Thereafter, the operation between times t1 and t5 is repeated.

When there are no originals in the container 6 at time t4 (original detector 10 is turned off), the rollers 36, 37, and 51 stop.

However, since the discharge roller 52 continues to rotate, the amount of film in the storage chamber gradually decreases thereafter.

Then, at time t5, when a document is added to the container 6, the photographing operation is restarted, the amount of film in the storage chamber increases, and the same operation as described above is repeated.

However, the additional document must be placed in the container 6 before the amount of film in the storage chamber becomes less than the third set amount σ.

If there is no original to be added after this (may be before restarting photographing), the original adding switch 115 is switched so as not to add the original.

Then, after the document in the container 6 is exhausted again and the document detector 10 is turned off, at time t7, the amount of film in the storage chamber becomes a third set amount σ(
If the amount of film is less than this (then the film will be stretched between the rollers 5L52, causing problems such as damage to the film), a signal of "1" will be sent from the output terminal C of the first counter.
'' signal is output, this signal opens AND gate G7, and flip-flop F4 is set via OR gate G24.

On the other hand, at time t7, the document addition switch 115 outputs the "10" signal, and the document feeding detector 25 outputs the "10" signal when it detects the first document sent to the photographing position.
1'' signal sets the flip-flop F1, and when the document detector 10 turns off, the AND gate G3 is open, so when the flip-flop F4 is set, the AND gate G8 opens, and the OR gate G
The film drive circuit 101 is operated via the film drive circuit 2o, and the capstan roller 35, feed roller 37, and supply roller 51 are rotated, and the film F in the photographing section is idly fed.

Also, by opening the AND gate G8, the AND gate G1.
This AND gate G11 opens every time a pulse from the first pulse generator 55 is input, and this pulse is counted by the second counter 107.

Immediately after the film is skipped forward and the trailing edge of the final exposure area of the film passes the cutting position of the cutter 45, when the count value of the second counter 107 reaches a predetermined value, an "l" signal is output from its output terminal F. The output signal activates the mono multi circuit 108, and the output signal of the mono multi circuit 108 drives the cutter 45 via the cutter drive circuit 109 to cut the film.

Therefore the exposed area of the film is the unexposed area of the film:
Separated from the area, all relevant document information is recorded on a single piece of film.

On the other hand, the output signal of the monomulti circuit 108 opens the OR gate G26, and the flip-flop F is set.

Therefore, AND gate G2 closes and capstan roller 3
5. The feed roller 37 and supply roller 51 stop, and the film is no longer fed.

The cut film pieces are continuously fed to the processor section 2 by the discharge roller 52, and when the trailing edge of the film pieces, i.e. the cut portion of the film pieces, passes the film detector 70, the film detector 70 is turned off. .

When the detector 70 is turned off, the AND gate G6 opens every time a pulse from the second pulse generator 102 is input to the AND gate G6, and this pulse is counted by the third counter 118.

The cut film piece fed into a part of the processor is fed by a driving roller of the processor part, and when the rear end of this film piece passes the discharge roller 85, the metering device of the third counter 118 reaches a predetermined value. Then, a "1" signal is output from the output terminal H, and this signal causes the mono multi circuit 11
9 is activated, the OR gate G25 is opened by the output signal of the monomulti circuit 119, and each circuit is reset and set to the state before the start of photographing.

After that, if another unit of original is placed in the container 6, photography is automatically performed in the same manner as described above, and information of one unit is recorded on another piece of film.

Next, a case will be described in which the mode selection switch 111 is switched to a mode in which the contacts are connected to perform photographing.

After the start of shooting, storage room 5 is
When the film amount within 0 increases and the film amount reaches the first set amount A', a "1" signal is output from the output terminal A of the first counter 105, and the alarm 106 is activated.
The electromagnetic clutch 65 is not activated and the discharge roller 52 remains stopped.

Therefore, film advance in a portion of the processor is not performed.

After that, when shooting continues, when the amount of film in the storage chamber reaches the second set value B', the "l" signal is output from the output terminal B of the first counter 105, and this signal stops the supply of originals. and photography is prohibited.

After that, the amount of film in the room remains constant without increasing or decreasing.

Therefore, from the start of shooting until the amount of film in the storage chamber reaches the second set amount, the document can be photographed at arbitrary time intervals, and images can be taken intermittently at long intervals. However, there is no problem.

Next, turn on the power switch 1 at any time after starting shooting.
20 is turned off, the output of inverter v6 becomes "1", and the AND gate G1o is opened, the second clutch 65 is turned on, the discharge roller 52 is rotated, and the film in the storage chamber is removed from the processor. sent to.

On the other hand, the flip-flop F4 is set by opening the AND gate G1°, and when the entire document has been photographed, the AND gate G18 is opened, and the film is then fed a certain length in the same manner as described above, and then the film is cut. be done.

Then, the rear end of the cut film piece is placed on the discharge roller 85.
When passing through, the power supply to all devices is cut off, and the power to all devices is cut off.

Incidentally, the film may be fed immediately when the power switch is turned off.

A mechanism for maintaining power supply to all devices for a certain period of time after the power switch is turned off is known, for example, using a timer that is linked to the power switch and causing the timer to maintain the power supply for a certain period of time.

As described above, according to the present invention, there is no risk of the film being scratched due to slippage between the feeding means and the film, and the exposed portion of the film is not sent to the processing means during exposure. Therefore, there is no problem even if the exposure operation is interrupted for a long time, and the film is not wasted.

Further, there is no need to use a special processing solution to cope with long interruptions in exposure work as in the conventional method, and development processing can be carried out using a normal development method.

Further, when developing the exposed film after exposure, the exposed portions of the film can be continuously developed, so the exposed portions of the film can be processed under the same conditions.
