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 image.

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 carried out intermittently, sometimes with interruptions for quite a long time, so the film is sent intermittently from the exposure section to the processing section after development, and if the exposure interruption time is long, 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 to store the film during recording 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, the film may be stretched between the recording section and the storage chamber. may be damaged or
There are problems in which the film is unnecessarily drawn out from the recording section, or the film is scratched due to slippage between the film and the drive roller that continuously feeds the film in the storage chamber to the processing section. This method has disadvantages in that it is necessary to store an appropriate amount of film in the storage chamber before recording starts, and it is not possible to take a long interruption time.

The present invention provides an image recording device that eliminates the above-mentioned drawbacks.

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

First, before starting photographing, the microfilm F is set between the capstan roller 35 and the pinch roller 36, and 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 rung 22 lights up, and the developer is heated.

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

Further, each counter and each of the seven lip-flops 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 1 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 (at the same time, the capstan roller 35, feed roller 31, and supply roller 51 rotate via the film drive circuit 101, and the film F is fed. be done.

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 70 tab F is set in response to a 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 G2o.

At this time, since there is no film at the film detection position of the film detector 10, the AND gate G is opened, and the output signal of the AND gate G1 causes the first electromagnetic clutch 6 to open.
0 is turned on, and the discharge roller 52 rotates.

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.
It is driven via the processor drive circuit 121 by the set side output signal of the flip-flop F6 set by the ON operation, and thereby the rollers 84 and 8 of a part of the processor are driven.
5. The drum 90°91.92 rotates 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 feeding roller 31 advances, passes through the cutter 45, is caught by the feeding roller 51, and is then sent to the storage chamber by the feeding roller 51, where it passes through the film guide member 53 (inside the storage chamber). After traveling along, the paper 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 10, 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 spreading and being damaged, and from causing damage to the film due to slipping between the discharge roller and 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 10 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, the ejection roller 52 is stopped, so a loop of film is formed in the storage chamber 50, and the amount of film in the storage chamber is reduced.

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, at time t.

indicates the time when the leading edge of the film was detected by the film detector 10, and the time is determined according to the progress of shooting.

After to, 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 Noritsu. 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 70 knob F2, or gate G
2. The second electromagnetic clutch 65 is turned on via
The ejection roller 52 is drivingly coupled to the drive source of the processor part 2 .

Therefore, the discharge roller 52 feeds the film in the storage chamber to the processor part 2 at the same speed as the rollers 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 10 is in the on state, the second
The pulses from the pulse generator are sent to the first counter 105 through the analogue Gs, and are decremented by the first counter! It is counted.

The film discharged from the storage chamber is developed, fixed, washed with water, and dried in the processor section 2, and then discharged to the tray 86.

After this, when the shooting operation continues, the amount of film discharged from the storage chamber is smaller than the amount of film supplied to the storage chamber. 2 set amount B' (if the amount of film in the storage chamber is larger than this, problems such as damage to the film will occur), and the output terminal B of the first counter 1105 is reached.
A “1” signal is output from the flip-flop F.
3 is set.

AND gate G2 by setting Noritsubu flop F3
is closed, and the solenoid 8 is activated via the lunoid drive circuit 110.
is turned off, 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 A' is reached again, a "1" signal is output from the output terminal A of the first counter 105, and this signal resets the Noritsu flop F3, which opens the AND gate G2. The supply of originals begins again, and the photographing work resumes.

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

At time t4-C@When there is no more original in the device 6 (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 value σ.

If there is no original to be added after this (or even before restarting the photographing), the original adding switch 115 is switched so as not to add an 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 C which is much smaller than the first set amount A'.
'(If the film amount is smaller than this, the roller 51°5
When the film is stretched between 2 and 2, causing problems such as damage to the film, a "1" signal is also output from output terminal C of the first counter, and this signal opens AND gate G7, which opens OR gate G24. through flip-flop F4
is set.

On the other hand, at time t7, the document addition switch 115 outputs a "0" signal, and the document feed detector 25 outputs a "1" signal when it detects the first document fed into the photographing position, causing the flip 70 to rotate. Since AND gate G3 is open when F1 is set and the document detector 10 is turned off, AND gate G8 is opened when flip 70 knob F4 is set, and the film drive circuit is connected via OR gate G2o. 101 operates, and the capstan roller 35, feed roller 31, and supply roller 5
1 rotates, and the film F in the photographing section is 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 rear end of the final exposure area of the film passes the cutting position of the cutter 45, the second counter 101 reaches a predetermined value, and a "1" signal is output from its output terminal F. This signal activates the mono multi circuit 108, and the output signal of the mono multi circuit 108 drives the cutter 45 through the cutter drive circuit 109.
is driven and the film is cut.

The exposed areas of the film are thus separated from the unexposed areas of the film, and all relevant original 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 resets the flip-flop F4.

Therefore, AND gate G8 closes and capstan roller 3
5. The feed roller 31 and the supply roller 51 stop, and the film is no longer fed idly.

The cut film pieces are continuously fed to the processor part 2 by the discharge roller 52, and when the rear end of the film pieces, ie the cut part of the film pieces, passes the film detector 70, the film detector γ0 is turned off. .

When the detector γ0 is turned off, this 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 sent to the third counter 118.
is counted.

The cut film piece fed into a part of the processor is fed by a drive roller of the processor part, and when the rear end of this film piece passes the discharge roller 85, the count value of the third counter 118 reaches a predetermined value. Then, an Ill 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 mono multi-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, the photographing 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 photographing is performed by switching the mode selection switch 111 to a mode in which the contacts are connected.

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 11'' signal is output from the output terminal A of the first counter 105, and the alarm device 106 is activated, but the second electromagnetic Clutch 65 is not activated and discharge roller 52 remains stationary.

Therefore, film feeding to 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', a signal "1" is output from the output terminal B of the first counter 105, and this signal causes the document to be fed. will be stopped and photography will be prohibited.

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

Therefore, from the start of photography until the amount of film in the storage chamber reaches the second set amount B', the original can be photographed at arbitrary time intervals, and photography can be performed intermittently at long intervals. Even if it happens, there will be no problem.

Next, turn on the power switch 1 at any time after starting shooting.
When 20 is switched off, the output of inverter V6 becomes "1", so AND gate G1o opens and the second
Clutch 65 is turned on and ejection roller 52 rotates to advance the film in the storage to the processor section.

On the other hand, when the AND gate G1o is opened, the flip-flop F1 is set, and when all the originals have been photographed, the AND gate G8 is opened, and the film is then fed for a certain length in the same manner as described above, and then the film is cut. Ru.

When the rear end of the cut film piece passes through the discharge port 85, the power supply to all the devices is cut off, and the power to all the 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.

Therefore, while information is being recorded on a single piece of film, even if there is a part that has already been recorded, that part will not be developed unless the user operates a switch, making it easier for the shooting process. There is no problem even if the process is interrupted for a long time, and all information can be stored on a single film of any length.

Therefore, since mutually related information can be recorded on a single film, there is no need for editing later.

Further, it is possible to obtain a film piece of any length on which all information is recorded within the amount of film that can be stored in the storage chamber, and it is possible to record one unit of desired information on the same film.

As described above, according to the present invention, the film is not scratched due to slippage between the feeding means and the film, and the film in the storage chamber is not stretched and damaged, and during exposure. Since the exposed portion of the film is not sent to the processing means, 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 liquid to cope with long interruptions in exposure work as in the past, and a regular development process can be performed using a normal development method.
