Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a recording device such as a microfilm camera used for recording objects to be recorded such as checks, bills, stock certificates, slips, etc.

2. Description of the Related Art Conventionally, recording devices such as microfilm cameras have been equipped with an automatic feeding device for recording objects in order to increase feeding capacity and work efficiency. This automatic feeding device is a device that feeds one unit of recording media one by one, but if recording media of different paper quality, paper thickness, etc. are mixed, double feeding may occur. A double feed detection mechanism is provided to stop the drive of the feeding device. It also has a mechanism for canceling the drive stop. Therefore, if a double feed occurs, the feeding of the double-fed recording medium is stopped, but if the double-fed recording medium is stuck in the automatic feeding device, an external In many cases, it is not possible to take out the double-feeding recording objects, so in this case, activate the drive stop release mechanism to let the double-feeding recording objects pass through the photographing unit and eject them to the outside. , it's like taking it out. However, it is undesirable for double-fed recording objects to be recorded on the film when they pass through the photographing section, as this wastes the film and causes confusion when the photographic film is used later. Also, the number of sheets counter will also advance, so
It becomes impossible to correspond with the recording medium, which is inconvenient for work.

In order to eliminate the above-mentioned drawbacks, some cameras are equipped with a switch on the operation panel that prohibits the operation of the number of shots counter, but when double feeding occurs, after operating the switch, the drive stop release mechanism is activated. The operation becomes complicated because you have to take out the double-feeded recording objects and then operate the switch again to return them to the shooting-ready state, and in the unlikely event that you forget to return the switch to the shooting-ready state, you may have to carry out feeding operations. If this continues, all the work and film after the double-feeding recording medium is ejected will be wasted.

In order to improve the above-mentioned drawbacks, the present invention is designed to prohibit photographing and the operation of the number counter for a certain period of time in conjunction with a drive stop release mechanism.

A recording apparatus according to the present invention includes: a recording means for recording a recorded object onto a recording medium; a driving means for the recording medium;
The apparatus comprises a feeding means for recording objects, a detection means for detecting double feeding of recording objects, a storage means for storing detection of double feeding of recording objects, and a canceling means for canceling the storage means, and The driving of the recording means, the driving means, and the feeding means is prohibited by a signal from the detecting means, and when the releasing means is operated, the storing means is canceled and the prohibition of driving of the feeding means is canceled. It is characterized by this.

The present invention will be explained below with reference to the drawings. FIG. 1 is a schematic diagram of a microfilm camera showing an embodiment of the present invention. The illustrated microfilm camera includes a recording means A for recording recorded objects such as checks, bills, stock certificates, and slips on a recording medium, that is, a microfilm F, a driving means B for driving the microfilm F, and a driving means B for driving the microfilm F. A feeding means C that feeds the recording medium and a detection means D that detects double feeding of the recording medium.
and storage means E for storing detection of double feeding of recorded objects.
and a release means F for releasing the storage means.

In the illustrated embodiment, the feeding means C comprises an automatic feeding device 1, and the automatic feeding device 1 is used for recording objects 2 such as checks, bills, stock certificates, slips, etc., which are tilted so that they slide down. Tower stand 3 and guide plate 4
The recording medium 2 is provided with a feeding roller 5 that feeds the recording medium 2 one by one, and a separation roller 6.The feeding roller 5 is made of a material such as rubber that has a larger coefficient of stiffness than the separation roller 6, and is constantly moved as shown by the arrow. Let it rotate. The feeding roller 5 sends out the uppermost recording medium 2'. At the same time, the second and subsequent recording materials 2 are also being fed out, but the separation roller 6 stops the second and subsequent recording materials 2 until the first sheet is fed out, and feeds them one by one. The feed roller 5 and separation roller 6 are coupled to a power source (not shown) via a clutch (not shown) that controls the feeding operation.

Detection means D for detecting double feeding of the recording medium includes a roller 7, a double feeding detection roller 8, and a double feeding detector 9.
Consists of. The roller 7 receives power from the above-mentioned feed roller 5 via the idle roller 13. The double feed detection roller 8 is arranged opposite to the roller 7 and is attached to one end of the holding arm 11. The holding arm 11 is rotatably held by a fulcrum shaft 12, and a spring 13 presses the double feed detection roller 8 against the roller 7. Recorded object 2 fed by feeding roller 5 and separation roller 6
When the paper is bitten by the roller 7 and the double feed detection roller 8, the double feed detection roller 8 moves by the thickness of the recording medium 2. The double feed detector 9 is located at the other end 11' of the holding arm.
Therefore, when there is only one recording medium 2, it remains OFF,
When there are two or more sheets, double feeding of the recording medium 2 can be detected by setting it in the ON position. If the double feed detector 9 is held so that its position can be changed from the outside using a known technique, double feed can be detected depending on the paper thickness of the recording medium 2.

The recording means E is connected to the above-mentioned double feed detector 9 and stores the detection of the double feed of the recording medium by the detecting means D.

The release means F consists of a release detector 10 connected to the storage means E, which is attached to the guide plate 4 so as to be operable from the outside.
When activated, the double feed detector 9 is deactivated via the storage means E.

The recording medium 2 fed by the automatic feeding device 1 is detected by the illumination light source 14 and light receiving element 15 of the paper detector 107, and is further detected by a pair of feeding rollers 17 disposed in the photographing section 16. Therefore, after being fed to the photographing position between the two spaced apart glass flat plates 18 and 19 and photographed, it is discharged onto the tray 21 by a pair of discharge rollers 20.

The above-mentioned recording means A records the object to be recorded fed to the photographing position of the above-mentioned photographing section 16 on a microfilm.
It consists of a photographing device for recording at F', and is equipped with an exposure section 26 including a lamp 22 for illuminating the object to be recorded, a photographing lens 23, a shutter 24, and a slit 25.

A driving means B for driving the microfilm is configured to drive the microfilm supplied from the supply reel 27.
F' is fed by a capstan roller 28 and a pinch roller 29 and wound onto a winding roller 30.

In the above-mentioned microfilm camera, the objects 2 to be recorded are sequentially fed by the automatic feeding device 1. At this time, the recording medium 2 operates the shutter 24 based on the detection signal from the paper detector 107. This signal remains on until the recording medium 2 is ejected from the ejection roller 20. When the recording object 2 passes through the photographing position, the exposure section 2 is exposed by the photographing lens 23.
The image is projected onto the microfilm F' of No. 6, and photographed onto the film using a rotary rotation method using slit exposure.
As described above, the microfilm F' is wound around the supply reel 27, passes between the capstan roller 28 and the pinch roller 29 disposed in the exposure section 26, and is taken up onto the take-up reel 30. The pair of feed roller 17, discharge roller 20, and capstan roller 28 are coupled to the same driving source (not shown) and rotate while maintaining a constant rotation ratio. Further, the pair of feed rollers 17 and discharge rollers 20 are constantly rotating.

When double feed is detected by the double feed detector 9, the clutch (not shown) is activated by the signal from the detector.
It is turned OFF, and the driving of the photographing device, the microfilm driving device, and the recording medium feeding device is prohibited. However, after that, the release detector 1
When 0 is activated, the above storage device E is released and
The prohibition of driving of the feeding device 1 is canceled.

Hereinafter, the above drive control will be explained as shown in Figs. 2 and 3.
This will be explained with reference to the figures. FIG. 2 is a block diagram showing an embodiment of a circuit for controlling the operation of the microfilm camera shown in FIG. 1, and FIG. 3 is a timing chart thereof. When the power of the microfilm camera is turned on, the initial reset 101 causes the flip-flop 103 to be activated via the OR gate 102.
The output becomes high level "H", and the feeding drive circuit 104 of the automatic feeding device 1 is driven to become ready for feeding. A monomulti 105 connected to the output of the flip-flop 103 is activated when the signal changes from low level "L" to high level "H". Therefore, in the initial reset state 101, the output of the inverter 106 is at a high level "H". On the other hand, when the paper detector 107 detects the recording medium 2 fed from the automatic feeding device 1, this detection signal opens the AND gate 108, drives the shutter drive circuit 109 and the film drive circuit 110, and takes a picture. will be held. At the same time, the counter drive circuit 111 is also driven to count the number of sheets. Photographing is sequentially repeated in this manner.

When double feeding occurs during feeding, the flip-flop 103 is set by the detection signal from the double feeding detector 9, the output changes from "H" to "L", the driving of the feeding drive circuit is stopped, and the double feeding object is detected. The recording medium 2 stops while being sandwiched between the roller 7 and the double feed detection roller 8. At this time, the monomulti 105 does not operate, so even if double feeding is detected, all the recording objects 2 that were being fed in the microfilm camera device before the detection of double feeding are
Captured on film normally.

At the same time, the output Q of the flip-flop 103 becomes "H" and the alarm 112 is activated to notify the operator that double feeding has occurred. When the release detector 10 is activated in order to take out the recording material 2 that is being double fed, the flip-flop 103 is reset via the OR gate 102, the output changes from "L" to "H", and the feed drive circuit 104 is activated. The recording medium 2 that is being driven and fed in duplicate is a pair of feed rollers 1.
7, the image passes through the photographing section 16 and a pair of ejection rollers 20, and is ejected onto the tray 21. At the same time, the monomulti 105, which is set to operate until the double-fed recording materials 2 are ejected onto the tray 21, operates, so the output of the inverter 106 becomes "L", and the output of the AND gate 108 becomes "L". Detector 107
Since the shutter drive circuit 109, the film drive circuit 110, and the counter drive circuit 111 do not open even when the signal is output, the shutter drive circuit 109, film drive circuit 110, and counter drive circuit 111 do not drive. Therefore, when the release detector 10 is activated, the photographing operation is prohibited and at the same time, the counter is not incremented and returns to the initial reset state. At the same time, the alarm 112 is also released.

When the release detector 10 is operated, the output of the inverter 106 becomes "H" after a certain period of time, and when the signal from the paper detector 107 is output, the AND gate 108 opens and the shutter drive circuit 109 and film drive circuit 110 are driven. The ban will be lifted and filming will take place.

As described above, according to the present invention, by canceling the feeding stop, it is possible to take out the recorded object that has been stopped due to double feeding without photographing it on the film. Furthermore, since there is no need to operate an independent switch to prohibit photography, failures due to forgetting to switch the switch can be prevented. At the same time, the counter does not advance, so the number of recorded objects that have been photographed always matches the count on the counter, which is convenient for creating an index when using photographic film at a later date.
