Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for recording images on a recording sheet such as photographic film,
This is about the recording device that develops this.

In a recording device such as a processor camera, it is necessary to keep the feeding speed of the #i film substantially constant after development to prevent processing unevenness from occurring on the film. On the other hand, image exposure work is usually carried out intermittently, and is sometimes interrupted for quite a long time. Therefore, #'i film is intermittently sent from the exposure section to the processing section after development, and the exposure interruption time is In the long case, the film advance would be interrupted for a long time.

In order to adjust for such a difference in film feeding characteristics between the exposure section and the processing section, it is conceivable to provide a storage chamber between the KNN processing section and store the film exposed to the image K11i in this storage chamber. ing.

However, in such a recording device, a development switch is provided to instruct the film in the storage chamber to be sent to the processing section, and when the development switch is pressed, feeding of the processed SK film from the storage section is started. There is. If the exposure operation is interrupted for a long time after feeding the film to the processing section, the amount of film in the storage chamber will decrease, and when the amount of film stored reaches the minimum, the cutter will automatically remove the film between the exposure section and the processing section. The development processing of the exposed film is always carried out at a constant rate by cutting the film or by continuously feeding the unexposed film from the exposure section to the processing section during interruptions (idle feeding). However, if the film is cut every time the storage amount reaches its minimum, related images will be recorded on separate films, and these films must be spliced together in order to be used in a reader, etc. after processing. There are drawbacks.

Furthermore, if the unexposed film is continuously fed from the exposure section to the processing section during interruptions in the light-ray work, there is a disadvantage that the unexposed film is wasted, and the longer the interruption time is, the more the film is wasted.

The present invention is intended to provide a recording device that eliminates the above-mentioned drawbacks.

The present invention will be explained below with reference to specific examples shown in the drawings.

FIG. 1 shows a processor camera to which the present invention is applied, showing a camera section for photographing an image of an IFi original on film, and a processor section for performing photographic processing such as development on 2ti photographed film. An automatic document feeder 3 is disposed above the camera sl, and documents 5#i such as checks, bills, stock certificates, and slips are stacked and put into the customer@6. t
A rotatable lever, sF, that sends the original 5 out of the container.
A solenoid 9 for supplying a document that drives the i-lever lever is a spring connected to the end of the lever 70. When the solenoid 8 of the automatic document feeder is turned on, the lever oscillates against the force of the lever 9, and its tip/end hits the edge of the lowest document in the container 6, and one document is transferred to the photographing section. 15. 10#i
The am detector detects the presence or absence of a document in the container 6, and is composed of a microphone switch, which is turned on and outputs a "1" signal when a document is present in the container.

The original 5 sent out of the container 6 is sent at a constant speed to an illumination position located between two spaced glass flat plates 1F and 1B by a pair of feed rollers 16 provided in the photographing section 15. Then, the paper is discharged onto the tray 20 by a pair of discharge rollers 19.

The upper roller of the pair of feed rollers 6 is supported to be able to move vertically, and when a document is fed between the pair of feed rollers 16, the upper roller moves upward depending on the thickness of the document. , is detected by the document feed detector 25. This detector 25#i consists of a micro switch, which turns on when the document is fed between a pair of feed rollers 6, outputs a "1" signal, and remains on until the rear edge of the document passes the illumination position. maintain.

21 is a slit placed near the illumination position, and 22 is a lamp for illuminating the original.

The P-Ras 16 and 19 are connected to a driving source (not shown) of the photographing section, and are driven for a certain period of time when the original supply solenoid is turned on, so that the originals are fed at the same speed.

30#i projection lens, 31 a shutter, and 32 a slit. When the original a ki passes through the illumination position, the microfilm placed on the exposure section W29 by the projection lens 30! It is reduced and projected onto the top.

The microfilm 1 is wound around a supply reel 33, and a capstan roller 35 disposed in the exposure section [29;
It is fed at a constant speed by a pinch roller 36 and a pair of feed rollers 3). The capstan roller 35 and the feed roller 3 are connected to a drive source (not shown) of the welfare photographing section,
When the document feed detector 25 is turned on, it is driven and the film is fed at a speed equal to the moving speed of the document image on the surface of the capstan roller 35. Therefore, during photographing, the film at the exposure position is fed in synchronization with the feeding of the original.

38 is a roller that comes into contact with the outer surface of the film wound on the supply reel 33, and 39 is a freely drivable arm that supports the p-ra 38. These are used to detect the remaining amount of film wound on the supply reel. The K1g is configured to issue an alarm signal when the amount of film is less than a predetermined amount A.

A cutter for cutting 45II'i film, which is driven by a solenoid (not shown). 50#'i A storage room where the film sent from the photographing section is freely stored in a loop shape, with a pair of supply rollers 51 near the entrance and a pair of supply rollers 51 near the exit.
Pairs of ejection rollers 52 are respectively arranged ψ. The exposed film at the exposure position is fed to the storage chamber by a feed roller 51.

The film stored in the storage chamber is delivered to a portion of the processor by a discharge seam 252. Due to the difference in film feeding speed between the supply roller 51 and the discharge roller 52, a loop ν' of the film is formed in the storage chamber.

Supply roller 51 #i is coupled to the same drive source as capstan a-ra 35 and feed roller 37, and these rollers 35,
The film is fed at the same speed as No. 37. The pair of supply rollers 51 are held between them as shown in FIG. The pair of discharge rollers 52 also have the same shape as the supply rollers 51.

An Idy film guide member 53 is arranged between the supply roller 51 and the discharge roller 52, and the film guide member 53#
j It has protrusions 531 disposed near the small diameter portions of the rollers 61 and 52 at both ends, and vertical movement restricting portions 53 b that engage with the side edges of the film.

This film guide member 53 guides the leading edge of the film from the entrance to the exit of the storage chamber when the leading end of the film is fed into the entrance of the storage chamber, and also prevents the film from shifting laterally between the rollers 51 and 52. This works to ensure that a loop of film is formed.

In FIG. 3, a 55 pulse generator is used to supply roller 5.
It operates in conjunction with the rotation of 1 and generates a pulse every time the mouth → 5 rotates by a certain angle. The pulse generator 55 is composed of a cam disk 56 fixed on the axis of the supply roller 51, and a micro switch 57 turned on and off by projections provided at regular intervals on the surface of the cam disk 56.

In FIG. 1, there are an 8o#'i developing device, an 81.82F water washer, and an 83D dryer. The film F fed 9 from the camera section 1 to the processor section 2 is fed by a drive roller 84, developed with a developer in a developing device 8o, and then
After being washed with water at a temperature of 1.8i2 and dried with hot air from a dryer 83, the paper is discharged onto a tray 86 by a discharge roller 85. Feed drums 90, 91, and 92 are arranged in each of the liquid tanks of the developer 80 and the water washers 81, 82, respectively. is wound around each drum and fed automatically.

As the developer for the developing device 80, a monobath developing and fixing solution is used. Note that the developing process and the fixing process may be performed separately using separate shields. The drive roller 84, the discharge roller 85, and the feed drums 90, 91, and 92 are driven by the same drive source (not shown), and feed the film at the same speed.

Reference numeral 95 denotes a take-up reel used when viewing the film without cutting it.

The processor part 2 is provided with a so-called autoloading mechanism that automatically guides and feeds the film sent from the storage chamber 50.

FIG. 4 shows the drive mechanism of the discharge roller 52.

The shaft 52& of the discharge roller 52 is drivingly coupled to a drive shaft 61 via an electromagnetic clutch 60.

The drive shaft 61 is coupled to a drive source (motor) for the processor part 2. When the electromagnetic clutch 6o is turned on, the shaft 521
and a drive shaft 61 are drivingly coupled so that the discharge roller 52 advances the film at substantially the same speed as the processor portion 2.

Figure 5 shows one drive control path for the feeder of the ejection roller and part of the processor. A pulse is generated each time the roller 52 rotates by a certain angle, that is, each time the film is fed a certain length by the rotation of the discharge roller. 101#i An addition/subtraction counter for detecting the film storage weight in the storage chamber 5o, which adds and counts the pulses generated from the first pulse generator 55 mentioned above, and subtracts and counts the pulses generated from the second pulse generator 99. do.

101 and 102 indicate decoders, and the first decoder 101
outputs the l''IJ signal when the count value of the counter 1000 reaches the first set value, that is, when a first predetermined amount of film is stored in the storage chamber.

The count value of the second decoder 102Fi counter 100 is the first
When the second set value is smaller than the set value, that is, when a second predetermined amount of film set in advance has been stored in the storage chamber, a "1" signal is output. In this embodiment, the 1.0 set value of the first decoder log corresponds to the maximum amount of film stored in the storage chamber;
The second set value of the second decoder 102 is determined when the amount of film stored in the storage chamber is at its minimum (roller 51 and roller 52).
The film becomes straight between t! Respond to

Note that the set value ψ is not limited to the example.

06d Initial reset circuit that outputs the rlJ signal when the power switch is turned on, 107°108Fi OR gate, l12#i development start switch, 113#f rollers 84, 85 of processor part 2, dotA90.91.92, etc. A pull circuit that drives the entire film feeding mechanism;
8 resistors, Tr is a transistor, and Dt'i diode. It consists of a manual developing switch FD3 switch 112Fi, and when it is turned on, it outputs a 11'' signal. Timer 105Fi consists of a known timer and is activated when the AND gate 104 is opened, and when a set time has elapsed after activation, the I-"J (is number) is output.

Next, the operation of the above device will be explained. Before starting photographing work, the leading end of the film is pulled out from the supply reel 33, passed between the rollers 35 and 350, and loaded with the rollers 3 and 51 sandwiched between the discharge rollers 52. In this case, the film is loaded in such a way that no film loops are formed in the storage chamber 5°.

Load the film with the leading edge of the film 1 sandwiched between the discharge rollers 52, and then turn on the power switch.
When a bundle of originals is placed in the container 6, the originals are sent one by one to the photographing section 15. Furthermore, when the power switch is turned on, the 7-rip 7-o-rub circuit 103 is reset by a signal output from the initial reset circuit 106, and the counter 100 is set to r0.
It is reset to J. The p-Terra 3537, 51 rotates in conjunction with the feeding of the original to the photographing section, and the shutter 3
1 opens, film 1 is fed in synchronization with the original feed,
The original is photographed on film.

During the photographing operation, the ejection roller 52, the rollers 84, 85, which are part of the processor, and the drums 90, 91, 92 do not rotate.
As the roller 51 rotates, the photographed film is stored in the storage chamber 5.
0 and stored in the storage chamber 50 in a loop shape. Pulses generated from the pulse generator 55 as the roller 51 rotates are added and counted by a counter 100. The count value of the counter 100 increases as the film is fed into the storage chamber, and when it reaches the first set value, the first decoder 101 outputs the I'll signal, and this signal sets the 7-lip 70-tub circuit 103. .

When the 7-lip 70-tub circuit 103 is set, a 1-1'' signal is output from the output terminal Q, and this output signal drives the rollers 84, 8'5, The drums 80 to 81 rotate,
Further, the transistor Tr becomes conductive and the electromagnetic clutch 60 is turned on, thereby causing the discharge roller 52 to rotate. Through the above steps, the film in the storage chamber is fed to the processor part 2 and developed.

Fixed, washed, and dried.

On the other hand, due to the rotation of the discharge roller 52, the second pulse generator 9
A pulse is generated from 9, and this pulse is generated by counter 100.
is subtracted and counted. If shooting is interrupted after the start of feeding film from the storage chamber to a part of the processor, the amount of film stored in the storage chamber decreases, and when shooting is resumed thereafter, the storage amount increases. If the shooting operation is interrupted for a long time after starting to feed the film to a part of the processor, the count value of the counter 100 will decrease.
When the count value reaches the second set value, the second decoder 102 outputs a signal "11", and this signal causes the ant game) 10
4 is opened and the timer 105 is activated.

While the timer IL) 5 is in operation, the discharge roller 52 and the roller 84
．． 85. Since the drums 90 to 92 continue to rotate, the film at the shooting position is ejected to the storage chamber by the driving force of these rollers, and the unexposed film is fed from the supply reel 33 to the storage chamber. . By this empty feeding, the final exposed area on the film is sent to the storage chamber 50, and then developed in a 9980° water washer sx, 82. The discharge roller comes out through the dryer 83, and this signal resets the 7 lip 70 tube circuit 103, which causes the rollers 84, 85, drums 90 to
92 is stopped, and the electromagnetic clutch 60f)E is turned off to stop the ejection roller 52, so that the film is no longer fed. When the photographing operation is resumed after this, the photograph will be taken on a new film that is identical to the original.

If the photographing operation is completed before the first decoder 101 outputs the signal, that is, before the counter 100 reaches the first set value, the development start switch 12 is turned on. When the switch 112 is operated, the rlJ signal is output from the switch 112, and this signal causes the rollers 84, 85 and drums 90 to 92 to be activated via the processor part drive circuit 113.
rotates, and the electromagnetic clutch 60 is turned on, causing the discharge roller 52 to rotate.

Therefore, the film in the storage chamber is fed to the processor part 2 and processed. When the final exposure area on the film passes the cutting position of the cutter 45, the cutter 45
operates and cuts the film. When the rear end of the cut film passes the discharge roller 86, the 7-lip 70-tub circuit 103 is reset by the output signal from the timer 105, and the rollers 52, 84, 85 and drums 90-92 are stopped.

Set time #'1 of timer 105 is required to feed the trailing edge of the final exposure area on the film to discharge a-ra 85 after the film storage amount decreases and the counter 100 reaches the second set value. set to time.

By providing a known length measuring device for measuring the film feeding lid instead of a timer for measuring the film feeding lid, it is possible to accurately feed the film to a predetermined position.

However, in the present invention, the film feed is stopped after at least the rear end of the final exposure area has been developed, for example, when the rear end of the final exposure area passes through the developing device 80. I don't do monks either.

As described above, according to the present invention, when the sheet storage amount in the storage chamber reaches the first set electric value, the sheet feeding from the storage chamber to the processing section is started, and the sheet is started to be fed from the storage chamber to the processing section. 2
Since the sheet feeding is stopped after the sheet has been fed a predetermined length after reaching the set value of There is no need to waste sheets by cutting the sheets or feeding a large amount of sheets from the exposure section to the processing section during long interruptions. As a result, even if a document that has reached w4 is exposed intermittently with long interruptions, related documents can be recorded on a single sheet and stored, and this single film can be easily stored using a reader, etc. can be used.

Note that the sheet is not limited to microfilm, and various known photosensitive sheets can be used.
