Description

DETAILED DESCRIPTION OF THE INVENTION A. Object of the Invention [Field of Industrial Application] The present invention relates to a photographing device that sequentially photographs and records image information on a long film.

[Conventional technology]

A rotary camera is a typical example of the above-mentioned photographing device. The camera will be explained below as an example.

The rotary camera receives materials to be microfilmed and preserved, such as bills, checks, stock certificates, documents, drawings, etc., and processes the images by sequentially imprinting the image information of the materials onto a long film. This is an automatic photographing device that discharges photographed materials outside the device, and a large amount of information can be stored on one roll of long film set inside the device. It is used by administrative agencies to make microfilms for preserving materials and preventing accidents.

In some cases, the introduction of data into the device is done manually, while in others it is done automatically. There is also a system that allows image information on the front and back sides of the introduced material to be simultaneously imprinted on the upper and lower sides of the film surface in the width direction. Some are equipped with film developing machines.

[Problem that the invention seeks to solve]

For example, in banks, securities companies, etc., documents such as bills and checks that were issued on that day and should be preserved are photographed every day. As a general rule, one roll of long film in the device is not cut into pieces each day, but is used to photograph materials for many days until one roll is used up. Once the images have been photographed, they are developed and stored as a single roll of long microfilm containing several days' worth of photographic information.

In this case, in order to sort, search, edit, etc. the photographic information for each minute of the photographing date contained in the series of one volume of long microfilm created above, at the beginning of the daily document photographing work, A sheet with the date written on it is introduced into the device and the date sheet is imprinted, and then the stored material is started to be introduced into the device. Write large enough to be visible.

However, this was a cumbersome task as a date sheet had to be prepared every day.

A rotary camera with a developing device has a built-in date data imprinting means that operates in conjunction with the operation of a film cutter, and transfers the photographed film portion of that day from the photographed film dock section to the developing section every day. A device has been devised in which date data is imprinted during the operation of a film cutter, etc., but the resulting microfilm is cut into pieces of one day's worth, and the length can be adjusted depending on the amount of daily photographic processing. There are many problems with subsequent organization and storage management, and the date cannot be imprinted unless the photo is developed. When the image is developed, only the date of the last photograph (the date of development) is imprinted.

Also, each time a predetermined length of long film is photographed (including a blank feed), a cutter is operated to cut the film to a fixed length, and when the cutter is operated, the date is copied. A device has also been devised in which a cutting mechanism is operated to imprint the date and time on the leading edge or trailing edge of a film cut to a fixed length. However, with this product, the microfilm obtained is a film cut to a regular length every day.
Similar to the above example, there are problems with organizing and storage management after wA. In addition, for microfilm taken on days when the amount of processing is less than the amount that can be taken with the above-mentioned standard length cut film, the length of the film after the last frame becomes a blank space and is wasted; Since multiple lengths of microfilm are produced, there are problems with subsequent organization and storage management.

The present invention has been proposed in view of the above, and is a method for copying daily dates when a roll of long film is used for document photography over several consecutive days without cutting it for each day's shooting. The purpose of the present invention is to provide a device that allows complicated procedures to be easily performed without any trouble.

1. Structure of the Invention [Means for Solving the Problems] The present invention provides a photographing apparatus that sequentially photographs and records image information on a long film, in which at least the daily date is automatically displayed by a clock means. Alternatively, the film is characterized by being equipped with a date imprinting mechanism including a date display that can be operated manually, and means for detecting the non-advancement of the film and activating the date imprinting mechanism when the non-advancement is completed. The gist is the photographic equipment used.

[For production]

In other words, when a roll of long film is not cut for each day's shooting and is used for document shooting over several days in a row, the device power switch must be turned on at the start of daily shooting work. After that, a certain amount of film advance is always performed before the date imprinting process and then the introduction of the first photographic material of the day into the apparatus. This is done by inserting, for example, a non-photographed film portion of several frames in length between the last photographed frame of the previous day's photographic frame group and the photographic frame group starting with the next day's date photographic frame. This is because the non-photographed film portions are formed by processing, and the non-photographed film portions are used to clearly separate groups of daily photographed frames on the film, thereby facilitating subsequent searches.

The present invention pays attention to the above-mentioned film feeding procedure that is always performed at the start of daily photographic work, and automatically imprints the date in conjunction with the film feeding process.

That is, with the above configuration, if the above-mentioned film feed is performed before the first photographic material is introduced into the device at the start of daily photographing work, the date imprinting mechanism is activated at the end of the film feed. The date of the day, which is automatically displayed by a clock means or manually displayed in advance, is automatically imprinted on the date display of the mechanism.

FIG. 5 is a diagram of a date frame 53 on a developed film roll with a date (year, month, day) 51 and time 52 imprinted on it.
The photographed frame group 54 on the left side of the frame 53 in the drawing is the material imprinted for that date, and the photographed frame group 55 on the right side is the material imprinted for the previous day. This is a non-photographed film portion with a length of several frames formed between the last photographed frame 55n of the photographed frame group 55 for the previous day and the date frame 53 of the next day.

Due to the existence of this non-photographed film part, the daily photographed frame groups 55 and 54 are clearly separated, and subsequent searches and the like are facilitated.

1. Start rotating the film take-up reel 15,
The rotational drive is stopped by the rear end detection signal of the document from the second sensor S2. Also, when the film jump button 42 is pressed, the capstan roller 11 and
The film take-up reel 15 is brought into rotation. 28

Next, the operation will be explained.

(1) When the device power switch 41 is turned on to start photographing work on -day, a reset pulse is output from the initial reset circuit 26 and input to the counter circuit 30 and FF circuit 31 via the OR gate 36, and the like. will be reset.

(2) Next, when the film feed button 42 is pressed, the film feed drive circuit 27 is activated, and as long as the button 42 is kept pressed, the capstan roller 11 and the take-up reel 15 are activated.
is held in a rotationally driven state, and film feeding, that is, blank feeding of the film is performed.

(3) On the other hand, when the film jump button 42 is pressed, the clock circuit 28 is activated and the first AND gate 29 is activated.
The input of clock pulses to the counter circuit 30 is started via the counter circuit 30, and the amount of film skip feeding is counted by the counter circuit 30 while the film skip feed button 42 continues to be pressed. It is displayed on the display 43 of the operation panel 4.

(4) The above-mentioned film empty feed amount count value is the counter circuit 30
When the preset count value is reached, the arrival signal is input from the counter circuit to the FF circuit 31 and the FF circuit 3
1 is set. At this time, it may be preferable to notify the above-mentioned arrival with an alarm such as a lamp or a buzzer provided on the operation panel 4.

(5) When the operator confirms on the display 43 or the alarm that the film empty feed amount has reached a predetermined amount, he releases the press of the film empty feed button 42. Then, at that point,
Film feed is stopped. The output of clock pulses from the clock circuit 28 is also stopped. The output from the FF circuit 31 set to the second AND gate 32 and the output from the inverter 45 to the second AND gate 32 based on the release of the film jump button 42 cause the second
The AND gate 32 opens and a start signal is output from the MM circuit 33 to the date imprinting circuit 34, which controls the lighting of the lamp 23 of the date imprinting mechanism 21 for a certain period of time, and the transmissive liquid crystal panel as a date display. 22 and clock circuit 24
The date and time of the day and time automatically displayed in 51.
52 (FIG. 5) is automatically imprinted. Therefore, between the imprint position on the film at date and time 51 and 52 and the last photographed frame of the previous day's photographic frame group, there is a gap between the daily photographic frame groups by the above-mentioned film feed procedure. Non-photographed film part sentence for the required length (Figure 5)
This is the form in which it existed. Further, the output signal of the MM circuit 33 is input to the OR gate 36, and the output signal of the MM circuit 33 is input to the OR gate 36, and the output signal of the MM circuit 33 is input to the OR gate 36,
1 is reset and the device enters the standby state.

(8) Next, when the material to be photographed and processed is inserted into the input port 2, the insertion is detected by a sensor (not shown), and the detection signal activates the material transport mechanism (not shown), and the material is transferred into the device. It is drawn in and conveyed through the internal passage 60 at a predetermined speed. When the sensor detects that the leading end of the conveyed material 0 has reached the first sensor S1 position, the film feeding circuit 27 is started at that point to rotate the capstan roller 11 and the take-up reel 15, that is, to feed the film. will be started. Further, the document illumination lamp 18 is turned on.

Material 0 (image surface facing downwards) is slippery due to subsequent transportation) 6
In the process of passing through section 0a, the slit is illuminated by the lit lamp 18, and the reflected light of the illumination light on the material surface passes through the optical system 17 including the mirror 19 and lens 20, and then reaches the second film guide roller. An image is formed on the surface of the film F in the feeding state at exposure position 10, and the image information of the material is imprinted onto the film portion next to the date and time imprinted frame 53 by slit exposure. The feeding speed of the film F is set at a reduction rate times the feeding speed of the material O.

(7) When the second sensor S2 detects that the rear end of the transported material O has passed through the second sensor S2, the film feeding is stopped and the lamp 18 is turned off at that point.

The material O, which has passed through the slit 60a and has been photographed, is continuously conveyed and discharged into the discharge box 3.

(8) Thereafter, each time a material is introduced into the apparatus through the input port 2, the operations of (8) and (7) above are repeated, and the material is sequentially photographed on the film F.

(8) Since the date imprinting circuit 34 does not start unless the film is rapidly advanced by a predetermined amount or more, if necessary during the sequential photographing process of the material, the film can be rapidly advanced by the predetermined amount or less using the film advance button 42. By doing this, the space interval between the photographed material frames can be changed to the normal space interval α (
(FIG. 5) As described above, it is possible to arbitrarily adjust the width or narrowness within a predetermined amount or less without imprinting the date.

Note that the normal space interval α between photographed frames is the first sensor S.
The distance from the position of l (Fig. 2) to the edge of the slit 16 on the sensor side, from the position of the second sensor S2 to the edge of the slit 16) 6
It is defined by the distance to the edge of Oa on the sensor side and the feed speed of the film F.

The slit exposure position of document 0 with respect to film F is the second
For example, the capstan roller 1 is located downstream of the date imprinting mechanism 21 in the film feeding direction as shown by the two-dot chain line in FIG.
1 position. FIG. 4 is an operation control block circuit diagram in this case, and a second inverter 37 is added to the circuit of FIG. 3.
- A second MM circuit 38 and a second OR gate 39 are added.

The device operations from turning on the device power switch 41 until the date is imprinted are as shown in (1) to (5) in the example in Fig. 3 above.
It is the same as before.

Then, as described in (5) above, the date is imprinted on the film using the output signal from the first MM circuit 33.

On the other hand, the output from the first MM circuit 33.

The signal is input to the second inverter 37, which inverts the output signal of the first MM circuit 33, so that after the date imprinting process is completed, the second MM circuit 38 is activated to generate a pulse for a certain period of time. This pulse causes the second
The OR gate 39 is opened, the film advance drive circuit 27 is restarted, and the film is automatically advanced. By this film feeding, the film portion K on which the date and time has been imprinted moves from the capstan roller 11 to the third guide roller 12 side. Then, at the date imprinting mechanism 21 position, the rear end A of the film portion on which the date and time have been imprinted goes around the capstan roller 11 and reaches a position A that is slightly off from the slit exposure position toward the third guide roller 12. At this point, the pulse output for a certain period of time from the second MM circuit 38 ends, and film feeding also stops, and the apparatus enters a standby state.

Thereafter, the sequential photographing process of material 0 is performed in the same manner as in (6) to (9) above.

In addition to the above-mentioned embodiment in which the film is fed repeatedly by a predetermined length depending on the length of time the button 42 is pressed, the film may be fed intermittently by a fixed length each time the button 42 is pressed once. The mechanism is arbitrary, such as one in which the feed can be made by any length that is twice as long as the number of times the button is pressed, or one in which the feed length can be specified with a dial rather than a button.

The date imprinting mechanism 21 is not limited to the one using the date display using the transmissive liquid crystal panel 22 of the embodiment, but also includes other types, such as a numbering license plate in which the date and time are digitally displayed using the clock circuit 24. The date and time display 22 may be one in which the date and time displayed on a display such as a formula is illuminated with an illumination lamp and imprinted on the film surface by an imaging optical system.
The date and time may be displayed in advance by operating an operating member provided on the operation panel 4 before the date imprinting process.

In addition, other characters (sub information, targets) such as top title, subtitle, end title, blip, serial number, etc. can be displayed together with the date and time display by the clock circuit 24 on the transparent liquid crystal panel 22, or the date and time display can be switched. Connect the sub-information input circuit to display the required sub-information along with the date and time by operating the keys on the operation panel 4 as necessary.
Alternatively, by displaying only the sub-information, other necessary sub-information can be imprinted onto the film at any time.

Apart from the display 22 for displaying the date and time by the clock circuit 24,
It is also possible to provide a sub-information imprinting mechanism including a display device such as a liquid crystal type for displaying sub-information, and to imprint sub-information as described in F at any time.

C1.
