Description

The present invention relates to a photographing apparatus for sequentially photographing and recording image information on a long film. [Related Art] A typical example of the above-described photographing apparatus is a rotary camera. Hereinafter, the camera will be described as an example. Rotary cameras are converted into microfilms and materials to be preserved, such as bills, checks, stock certificates, documents, drawings, etc., are successively introduced, and the image information of the materials is sequentially transferred to a long film and processed. The photographed material is an automatic photographing apparatus (hereinafter, abbreviated as an apparatus) for discharging the photographed material outside the apparatus. A large amount of information can be stored on one roll of long film set in the device. For example, in banks, securities companies, libraries, various offices, government offices, etc. Is used for microfilming. Some materials are introduced into the device by hand, while others are automatically introduced. In some cases, the image information of the front and back surfaces of the introduced material can be simultaneously imprinted on the upper and lower sides of the film surface in the width direction. Some are equipped with a film developing machine. For example, in a bank, a securities company, etc., every day, a photographing process is performed on materials such as bills, checks, etc., which should be stored on that day. One roll of long film in the device is not cut in length every day as a rule, but is used to shoot materials over many days until one roll is used up.
When the entire length has been photographed, the film is developed and stored as a single roll of long microfilm containing a series of photographing information for several days. In this case, in order to sort, search, edit, etc., the photographing information for each photographing day unit included in a series of the long microfilms made in the above-mentioned one volume at the start of the daily material photographing work, After the sheet on which the date is written is introduced into the apparatus, the date sheet is copied, and then processing for starting introduction of the stored material into the apparatus is performed. The date on the date sheet is written large enough to be of a size that is sufficiently visible on the developed film. [Problems to be Solved by the Invention] However, this has been troublesome because a date sheet has to be prepared every day, and it has been difficult to prepare the date sheet and to introduce it into the apparatus. Conversely, another operator who does not know the date imprint has already performed the imprint process again. In a rotary camera with a developing machine, for example, date data imprinting means that operates in conjunction with the operation of a film cutter is built in, and the photographed film portion of the day is transferred from the photographed film stock section to the developing section every day. A device that imprints date data upon operation of a film cutter or the like at that time has been devised. However, the obtained microfilm is cut in units of one day, and the length varies depending on the daily photographing processing amount, and there are many problems in the subsequent organization and storage management. In addition, since the date is not imprinted unless development is performed, if the development processing is not performed every day and the development processing is performed at once for many days, the final photography date (date of development processing)
Only the date is imprinted. Each time a predetermined length of film is shot (including idle feed), the cutter is activated to cut the film into fixed lengths, and the date is imprinted in synchronization with the operation of the cutter. There has also been proposed a device that operates a mechanism and imprints the date and time at that time on a leading end or a trailing end of a fixed length cut film. However, in this case, the obtained microfilm becomes a fixed-length cut film every day, and there is a problem in the subsequent organization, storage management, and the like as in the case of the above example. In addition, the film length portion after the end of microfilm shooting on the day when the amount of photographing processing is smaller than the photographable amount of the above-mentioned fixed-length cut film becomes blank and is wasted. Since any number of microfilms can be formed, there is a problem in subsequent organization and storage management. The present invention has been proposed in view of the above, and an object of the present invention is to provide a photographing apparatus devised so that date imprinting on a film for each photographing date is automatically and reliably performed. B. Configuration of the Invention [Means for Solving the Problems] The present invention relates to a clock circuit which is always kept in an operating state by a backup power supply in a photographing apparatus for sequentially photographing and recording an original on a long film, and a clock for the clock circuit. A display on which at least a daily date is displayed by an output of the circuit, date imprinting means for recording the date displayed on the display on the film, and memorizing that the date has been changed by the output of the clock circuit. Then, a storage unit whose storage is erased along with the recording operation of the date imprinting unit, and when the storage unit stores a change of the date, the date is recorded on the film according to the photographing operation of the original, Means for controlling so as not to record the date when the document is photographed when not stored. [Operation] With the above configuration, the date imprinting is automatically and reliably performed by the first subject detection signal after the date is changed, so that the above-described conventional problem is solved.

Reference numeral 15 denotes a film take-up reel supported on a shaft 16, which is driven to rotate in the direction of the arrow by rotation of the shaft 16 by a drive system (not shown). Reference numerals 9, 10, 11, and 12 denote a first guide roller, a second guide roller, a capstan roller (film winding roller), and a third guide roller of the film disposed between the film supply reel 7 and the take-up reel 15. is there. 13 and 14 are idlers (film pinch rollers) for the second film guide roller 10 and the capstan roller 11
It is. The film F on the side of the film supply reel 7 is set on the core of the film take-up reel 15 by suspending the start end side of the film F on the four rollers 9 to 12 manually or by automatic loading. . Reference numeral 60 denotes a transport passage in the apparatus for the photographing material O introduced into the apparatus from the input port 2; 60a, a slit provided in the middle of the passage; This is an exposure optical system, which includes a material illumination lamp 18, a mirror 19, an imaging lens 20, and the like. L is a slit exposure position for the film surface on the capstan roller 11, S1 is a first sensor for detecting that the leading end of the conveyed material has reached a position slightly before the slit 60a, and S2 is a rear end of the material for the slit 60a.

Power is supplied by, even if the power switch 41 of the device is turned off, it always works regardless of it,
A substantially accurate date and time is displayed on the liquid crystal panel 22. When it is midnight and the date is changed, the data detection circuit 26 operates and the first FF circuit (flip-flop) 27 is set. The first FF circuit 27 as the storage means is set by the data detection circuit 26 when the date is changed, so that the set state is a state in which the date change is stored and held. The second FF circuit (flip-flop) 39 is set by the output signal of the first FF circuit 27 and the detection signal of the material detection circuit 29. An initial reset circuit 28 generates a reset pulse when the power switch 41 is turned on. 29 is a material detection circuit including the transport material detection sensors S1 and S2 (FIG. 2);
30a / 30b / 30c are AND gates, 31/32 are first and second MM
Circuit (mono multi), 33 is inverter, 34a / 34b / 34c
Is an OR gate, 35 is a date imprinting circuit, and 36 is a film feed drive circuit. In particular, the FF circuits 27 and 39 and the MM circuit 31
32, AND gates 30a to 30c, and OR gates 34a to 34c constitute a state holding circuit. Next, the operation will be described. (1) The first FF circuit 27 is used to start the day's imaging work.
When the power switch 41 is turned on during the setting (the state in which the date change is stored), the initial reset circuit 28 operates,
The second FF circuit 39 is reset through the OR gate 34a. When the subject is conveyed in this state, the AND gate 30b is opened by the detection signal of the material detection circuit 29 including the conveyance material detection sensors S1 and S2, and the second output signal of the AND gate 30b is used.
FF circuit 39 is set. The AND gate 30a is set by the set signal of the second FF circuit 39.
Is opened, and a date imprinting pulse is output from the first MM circuit 31 to the date imprinting circuit 35 through the OR gate 34b. Thereby, the transmission type liquid crystal plate illumination lamp 23 of the date imprinting mechanism 21 is turned on for a short time, and the date and time displayed on the liquid crystal plate 22 are imprinted on the film surface portion between the second guide roller 10 and the capstan roller 11. . That is, the date and time are imprinted on the film automatically in conjunction with the conveyance of the subject. (2) On the other hand, the output pulse of the first MM circuit 31 is an inverter
33, the second MM circuit 32 operates in response to a rising signal after the date and time imprinting is completed, and a driving pulse signal is input to the film feed driving circuit 36 via the OR gate 34c. As a result, the capstan roller 11 and the take-up reel 15
Is started, and the film F is fed to the take-up reel 15 side. In this film feeding, the rear end A of the film portion K on which the date and time has been imprinted goes around the capstan roller 11 and slightly moves from the slit exposure position L to the third guide roller.
This is performed for the required length until reaching the position A 'off the 12 side. After the required length of film has been fed,
The material transport speed, the film feed speed, and the position of the material detection sensor S1 are set so that the leading end of the material reaches the slit portion 60a. The output pulse from the second MM circuit 32 is input to the FF circuits 27 and 39, and the FF circuits are reset. The reset state of the first FF circuit 27 is a state in which the storage of the date change is erased (a state in which the date change is not stored). The device then goes into a standby state. (3) When a material to be photographed is inserted into the slot 2, the insertion is detected by a sensor (not shown), and the detection signal activates a material transport mechanism (not shown) to draw the material into the apparatus. Then, the sheet is conveyed at a predetermined speed through the in-apparatus transfer path 60. When the leading end of the material O passes the first sensor S1 position and reaches the slit portion 60a, a drive signal is input from the material detection circuit 29 to the film feed drive circuit 36 via the AND gate 30c and the OR gate 34c. , Capstan roller 11
Then, rotation of the take-up reel 15, that is, film feeding is started. Further, the document illumination lamp 18 is turned on. Material O (downward on the image surface) is slit by subsequent transport
Go through section 60a. In the passing process, slit illumination is received by the lamp 18 in the lighting state, and the reflected light on the data surface of the illumination light is transmitted at the exposure position L of the capstan roller 11 through the optical system 17 such as the mirror 19 and the lens 20. Film F
An image is formed on the surface, and the image information of the material is sequentially transferred to the film F by slit exposure. The feed speed of the film F is set at a reduction rate times the transport speed of the material O. (4) When the passage of the rear end of the conveyed material O through the second sensor S2 is detected by the sensor, the material detection circuit 29 is detected at that time.
Then, a drive stop signal is input to the film feed drive circuit 36 through the AND gate 30c and the OR gate 34c, and the film feed is stopped and the lamp 18 is turned off. The material O, which has passed through the slit 60a and has been photographed, is continuously conveyed and discharged into the discharge box 3. (5) Thereafter, every time a material is introduced into the apparatus from the slot 2, the operations (3) and (4) are repeated, and the film F of the material is sequentially photographed. In this case, the power switch 41
Turn off the power switch 41 to resume shooting.
Is turned on, the date is not changed in the clock circuit 24 as long as it is within the same day, the first FF circuit 27 is not set, and the power switch 41 as described in (1) and (2) above is turned on. The imprinting of the date and time and the film feeding are not executed again in conjunction with the subsequent object feeding operation, and the introduction of the material into the apparatus from the slot 2 is resumed, so that the material is copied onto the material film F. Is sequentially executed from the next shot frame at the time of the interruption of the shooting operation. (6) Complete the shooting work for that day, and temporarily turn on the power switch.
When 41 is turned off and the power switch 41 is turned on to start shooting the next day, the clock circuit 24 changes the date at midnight from the previous day to the next day, and the data detection circuit 26 operates. Since the first FF circuit 27 is set, the second reset circuit is reset via the OR gate 34a by the initial reset circuit 28 when the power switch 41 is turned on.
Is closed. When the subject is transported in this state, the operations (1) and (2) of imprinting the date and time and feeding the film are automatically executed in conjunction with the transport. Thus, the date and time imprinting on the film prior to the start of the daily shooting operation is automatically and reliably performed in conjunction with the operation of transporting the subject. FIG. 4 is a view of a date frame 53 portion of the microfilm F 'on which a photographing date (year, month, day) 51 and a time 52 are imprinted.
A group of photographing frames 54 on the left side of the frame 53 with respect to the drawing is the material imprint for that date, and the group of photographing frames 55 on the right is a material imprint for the previous day. A switch 37 (first switch) for manually setting the first MM circuit 31
Figure) is provided, and a second
The MM circuit 27 can be set so that the date and time imprinting process can be performed again. The slit exposure position L of the material for the film F is the second position.
As shown by the chain line in FIG. 2, the second guide roller 10 is located upstream of the date imprinting mechanism 21 in the film feed direction, for example, and linked to the ON operation of the apparatus power switch 41 at the start of the photographing operation on that day. Then, the film is advanced by a predetermined length (at least until the last frame portion of the previous day's photographing positioned at the date imprinting mechanism 21 portion is disengaged from the mechanism 21 portion) by the film empty feed button 42 (FIG. 1). The length of the paper) and the date imprinting mechanism at the end of the empty feed
The date and time imprinting operation can be performed by turning on the lamp 23 of the lamp 21 so that the operation can be in standby. The date imprinting mechanism 21 is not limited to the type using the date display by the transmissive liquid crystal plate 22 of the embodiment, and other types such as a number ring / number plate in which the date and time are digitally displayed by a clock circuit 24, for example. The display date and time of a display such as a formula may be illuminated with an illumination lamp and transferred to the image forming optical system film surface. In addition, other characters (sub-information, target) such as trip title, subtitle, end title, blip, serial number, etc. are displayed together with the date and time by the clock circuit 24 on the transmission type liquid crystal panel 22, or the display is switched to the date and time display. The sub-information input circuit to be displayed on the display is connected, and the necessary sub-information is displayed by the key operation of the operation panel 4 together with the date and time display, if necessary.
Alternatively, by displaying only the sub-information and performing an operation of setting the second MM circuit 31 with the manual switch 37, the necessary sub-information can be imprinted on the film as needed. The clock circuit 24 is provided with a sub-information printing mechanism including a liquid crystal display or the like for displaying the sub-information separately from the display 22 for displaying the date and time, and the above-described sub-information is imprinted as needed. It can also be done. C. Effects of the Invention As described above, according to the present invention, the date imprint on the film is automatically and reliably imprinted on the film in conjunction with the signal of the first copy at the time of transporting the copy in the daily shooting operation. As described above, problems such as the trouble and trouble of the daily date sheet creation and forgetting to introduce the date sheet creation as in the related art are solved, and the intended purpose is well achieved.
