Description

DETAILED DESCRIPTION OF THE INVENTION A. Purpose of the Invention [Field of Industrial Application] The present invention relates to a photographing apparatus for sequentially photographing and recording image information on a long film.

[Conventional technology]

A typical example of the above-described image capturing apparatus is a transfer type camera. The camera will be described below as an example.

The transfer camera is made into a microfilm, and the materials to be preserved, for example, small documents, checks, stock certificates, documents, drawings, etc. are sequentially introduced, and the image information of the documents is sequentially printed on a long film. The photographed material is an automatic photographing device (hereinafter abbreviated as a device) that is discharged to the outside of the device.

A large amount of information can be stored in one roll of long film set in the device, for example, at banks, securities companies, libraries, various offices, public offices, etc. Is being used to make microfilm.

Some of the materials are introduced into the device by hand, and some of them are automatically introduced. In some cases, the image information of the front side and the back side of the introduced material can be imprinted on the upper and lower sides of the film surface in the width direction at the same time. Some are equipped with a film processor.

For example, at a bank or a securities company, every day, a photographing process is performed on materials such as bills and checks to be preserved that day. As a general rule, one roll of long film in the device is not cut into lengths that have been photographed every day, and is used to photograph materials for many days until one roll is used up, and the entire length is photographed. When finished, it is developed and stored as a roll of long microfilm containing a series of shooting information for several days.

In this case, in order to classify / search / edit the shooting information for each shooting day unit included in the series of one long microfilm created above, first, at the start of the daily material shooting work, After the sheet on which the date is written is introduced into the device and the date sheet is imprinted, the process of starting the introduction of the stored material into the device is performed. The date on the date sheet should be written large enough to be sufficiently visible on the developed film.

[Problems to be solved by the invention]

However, these date sheets have to be prepared every day, which is cumbersome, and it has been a forgotten task to make date sheets and introduce them into the device. Furthermore, the date sheet for the same date was mistakenly introduced many times, and the same date sheet was photographed multiple times. To search for the film that has been shot, the film frame (frame) on which the date sheet was shot is searched with a reader, but in order to facilitate this search, a space is available before the date sheet is shot. It was necessary to skip the film in order to open.

The present invention has been proposed in view of the above, so that the date is imprinted on the film for each shooting date, the counting mark is automatically and reliably made, and there is no space for facilitating the search during the search. The purpose is to provide a devised photographing device.

B. Configuration of the Invention [Means for Solving Problems] The present invention relates to a timepiece circuit which is always kept in operation by a backup power source in a photographing device for sequentially photographing and recording image information on a long film, and its A date imprinting circuit including a date indicator for displaying at least daily date by the output of the clock circuit, a mark imprinting circuit, and the power switch being turned on first after the date of the clock circuit is changed. And the storage means for storing the first ON operation of the power switch, the date data and the mark are imprinted on the film in response to the start of photographing the original, and the first ON operation is stored. If not, the image pickup apparatus is provided with date data at the start of image pickup and means for controlling so as to prohibit the imprinting of the mark.

[Work]

With the above-mentioned structure, the counting mark of the date imprinted film frame is automatically imprinted at the same time as the imprinting of the date during the day-to-day shooting work, which facilitates the search and blocks the date and subject. Since there is no space for each film, the film can be used effectively.

When it is desired to imprint the date and the mark for counting, the date imprinting switch 37 of the control unit 4 (FIG. 1) can be used for photographing. When the counting mark is not used, the counting mark imprinting circuit 30 can be turned off by the switch 38.

Next, the operation will be described.

(1) When the power switch 41 is turned on to start the shooting operation of one day, the initial reset circuit 28 operates and the second FF circuit 39 is reset through the OR gate 34a. When the subject is transported in this state, the transported material detection sensor S1
AND gate 30b by the detection signal of the material detection circuit 29 including S2
Opens, and the second FF circuit 39 is set by the output signal of the AND gate 30b.

The AND gate 30a is opened by the set signal of the second FF circuit 39, and the date imprinting pulse is output from the first MM circuit 31 to the date imprinting circuit 35 through the OR gate 34b.

As a result, the transmissive 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 is imprinted on the film surface portion between the second guide roller 10 and the capstan roller 11. . That is, the date and time are automatically imprinted on the film in conjunction with the transportation of the subject.

At this time, the counting mark circuit 30 automatically prints the counting mark on the film simultaneously with the date and time.

(2) On the other hand, the output pulse of the first MM circuit 31 is an inverter
The second MM circuit 32 is actuated by the rising signal after completion of the date and time imprinting, and the driving pulse signal is inputted to the film feeding driving circuit 36 via the OR gate 34c.

As a result, the capstan roller 11 and the take-up reel 15 start to rotate, and the film F is fed to the take-up reel 15 side.

In this film feeding, the rear end portion A of the film portion K (FIG. 2) on which the date and time is imprinted is the capstan roller.
The drive of the capstan roller 11 and the take-up reel 14 is performed at a time when it is wound around the slit exposure position L and reaches a position A ′ slightly deviated from the slit exposure position L toward the third guide roller 12 side. Turn off and stop.

Further, the output pulse from the second MM circuit 32 is input to the FF circuits 27 and 39 to reset the FF circuits, and the device is put in the standby state thereafter.

(3) When a material to be image-processed is inserted into the inlet 2, the insertion is detected by a sensor (not shown), and a material conveying mechanism (not shown) is activated by the detection signal, and the material is drawn into the apparatus. The sheet is conveyed through the in-apparatus conveying passage 60 at a predetermined speed.

When the arrival of the first sensor S1 at the leading end of the material O is detected by the sensor, a drive signal is input from the material detection circuit 29 to the film feed drive circuit 36 through the AND gate 30c and the OR gate 34c at that time. Capstan roller
The rotation of 11 and the take-up reel 15, that is, the film feeding is started. Further, the material illumination lamp 18 is turned on.

The document O (image surface facing down) is slit 60 by the subsequent conveyance.
Go through part a. Lamp that is lit during its passage 1
The slit light is received by 8 and the reflected light of the illumination light on the material surface is imaged on the surface of the film F at the exposure position L of the capstan roller 11 via the optical system 17 such as the mirror 19 and the lens 20, Image information of the material is sequentially printed on the film F by slit exposure. The feed speed of the film F is set to be the reduction rate times the conveyance speed of the material O.

(4) When the passage of the second sensor S2 at the rear end of the conveyed material O is detected by the sensor, the material detection circuit 29 is detected at that time.
From the AND gate 30c and the OR gate 34c, a drive stop signal is input to the film feed drive circuit 36 to stop the film feed and turn off the lamp 18.

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) After that, every time a material is introduced into the apparatus from the input port 2, the operations of (3) and (4) are repeated and the film F of the material is sequentially photographed.

In this case, when the power switch 41 of the apparatus is once turned off for lunch break or the like and then the power switch 41 is turned on for restarting the photographing work, the date is not changed in the clock circuit 24 as long as it is within the same day. FF circuit 27 is not set,
As described in (1) and (2) above, the imprinting of the date and time, the imprinting of the counting mark, and the film advancing are not executed again in synchronization with the subject feeding operation after the power switch 41 is turned on. By restarting the introduction of the materials into the apparatus, the imprinting of such materials on the film F is sequentially executed from the end of the last shooting frame at the time of the shooting work interruption.

(6) Turn off the power switch once the shooting work for that day is completed.
When 41 is turned off and the power switch 41 is turned on to start shooting work on the following day, the date is changed by the clock circuit 24 and the data detection circuit 26 operates at midnight from the day before to the next day. Since the first FF circuit 27 is set, the second FF circuit is reset from the initial reset circuit 28 through the OR gate 34a by turning on the power switch 41.
Is closed.

When the subject is conveyed in this state, the operations of (1) and (2) imprinting the date and time, imprinting the counting mark, and film feed are automatically performed in conjunction with this.

Thus, the imprinting of the date and time and the imprinting of the counting mark on the film prior to the start of the daily photographing work are automatically and reliably performed in conjunction with the operation of conveying the subject.

FIG. 4 is a view of the date frame 53 portion of the microfilm F ′, in which the photographing date (year / month / day) 51 and the time 52 are imprinted.
Is a counting mark imprinted on the date frame portion 53. A shooting frame group 55 on the left side of the frame with respect to the frame 53 is a material imprint for the previous day.

(See Figure), and if necessary, the second
It is also possible to set the MM circuit 27 so that the imprinting process of the date and time can be performed again. At this time, if the counting mark is not required, the counting mark circuit 40 is not operated by the switch 38.

The slit exposure position L of the material with respect to the film F is set to, for example, the position of the second guide roller 10 on the upstream side in the film feeding direction with respect to the position of the date imprinting mechanism 21 as shown by the dashed line in FIG. The film is moved by a predetermined length in synchronism with the ON operation of the power switch 41 of the apparatus or by the film skip button 42 (Fig. 1) (at least the portion of the previous day photographed at the date imprinting mechanism 21 portion). The length of time until the last frame part of the part comes off from the mechanism 21 part), and the date is imprinted at the end of the idling.
It is also possible to have an operation sequence configuration in which the date and time imprinting operation is performed by turning on the lamp 23 of 21 and the apparatus is put into standby.

The date imprinting mechanism 21 is not limited to the form using the date display by the transmissive liquid crystal plate 22 of the embodiment, and other such as a numbering / numbering plate in which the date and time are digitally displayed by the clock circuit 24. The display date and time of a display such as a formula may be illuminated by an illumination lamp and imaged on a film surface by an imaging optical system.

In addition, the clock circuit 24 displays the date and time on the transmissive liquid crystal panel 22 along with other characters (sub information, target), such as trip title, sub title, end title, blip, and so on.
A sub-information input circuit for displaying the serial number and the like, or for displaying the date and time in a switching manner is connected, and if necessary, the required sub-information can be displayed together with the date and time or the sub-information by operating the keys on the operation panel 4. By displaying only the information and performing the operation of setting the second MM circuit 31 with the manual switch 37, required sub-information can be imprinted on the film and treated.

In addition to the display 22 for displaying the date and time by the clock circuit 24, a sub information imprinting mechanism including a liquid crystal type display display for displaying the sub information is provided to perform imprinting of the sub information as described above. It can also be done.

The counting mark imprinting means 40 may be formed on the same display device 22 for displaying the date and time, or the mark may be formed by an LED or the like.

C. Effect of the Invention As described above, according to the present invention, since the date imprinting film frame counting mark is automatically imprinted at the same time as the imprinting of the date during the daily shooting work, the retrieval can be performed. It is easy and the film can be effectively used because there is no space for each block of the date and subject, and the intended purpose is often achieved.

Further, it is possible to prevent forgetting to imprint the date and erroneous work imprinting the same date a plurality of times.
