Description

[Detailed Description of the Invention] Unreleased IIj relates to a rotary type microfilm camera device, in which a desired character (sub information) 1 other than the original to be photographed, which is the main information, for the film, such as a blip (mark for retrieving film frames), The purpose of the present invention is to provide a system that allows shooting and processing of targets such as commands, date of shooting, operator name, top title, subtitle, end title, etc. in any format and layout.

A rotary microfilm camera device is configured to capture an image of a subject document onto a film (R light) using a slit'R light, and FIG. 1 is a schematic configuration diagram of an example thereof. When a sheet original O, which is the object to be photographed, is inserted into the original input slot 2 formed at the lower part of the front panel of the exterior casing L of the apparatus A, the original is drawn into the apparatus by a pair of pull-in rollers 3, and then passes through a guide plate 4, a pair of intermediate rollers 5, etc. The document is conveyed to the illumination section 7 at a speed V1 through a sheet path 6 in the apparatus, which is configured with It is discharged to the outside tray 9. When the sheet sensor Sl detects that the leading edge of the original reaches the illumination section during the process of transporting the original within the apparatus, the original illumination lamp IO is turned on in response to the signal, and the shutter 11 is turned on.
becomes open. Further, the operation of a film winding mechanism (not shown) is started, and the roll film (raw film) 12 is started to run in the direction of the arrow at a speed of V2=V, 7M (M: the reduction ratio of the document to the film). . As a result, the image of the original document passing through the illumination unit 7 at a speed of VI is connected from the leading edge to the trailing edge of Ifln, and then connected to the slit plate 13 within one frame range of the film 12, which is traveling at a speed of v2. The image is photographed by the image lens 14 using slit exposure. The winding of the film 12 is stopped after it has traveled the length of one frame. Further, the document illumination lamp 10 and the shutter 11 are turned off and closed when the sheet sensor S2 detects that the trailing edge of the document has finished passing through the illumination section.

In this way, by introducing the originals one after another into the apparatus A from the original input port 2, the originals are sequentially captured onto the roll film 12.

FIG. 2 is a plan view of the first few frames of an example of the developed film 12'. C is the photographed frame of each original as main information, and BN is the blip and frame photographed as sub information. Blips B in this example are of the same shape and size (1-level blip mode) and are photographed at the edge of one side of the film in correspondence with the positions of individual photographed original frames. Further, the frame number N is recorded on the film surface at the interval between the photographed frames of each original. Although the photographing of such sub information B-H on the film is omitted in the figure, there is a prep pattern photographing mechanism in the device, a numerical display counter that increments the displayed number one by one, and the displayed number is displayed on the film. A frame number capturing mechanism consisting of an optical system for reducing and projecting images onto a surface is built in, and the image is captured by the operation of these mechanisms.

However, the conventional rotary microfilm camera device as described above has the following problems.

(1) The format for capturing characters such as prep Bψ frame number N is specified in advance by the device, and only that specific type of format can be used for capturing. That is, for example, regarding blip B, its format is not only the 1-level blip format shown in FIG. 2, but also the format shown in FIG. 3(a).
A 2-level image captures two types of blips, page mark B (P) and file mark B (F), with different sizes and lengths, as shown in Figure (b). Take pictures of three types of blips: page mark B (P), file mark B (F), and batch mark B (B), which are in the form of a blip or have different sizes as shown in the same figure (C). There are various other formats, such as a deep 3-level blip format, but it is not possible to change to any of these formats if necessary.

(2) When photographing one roll of microfilm on -11k, it is called a goo-get, and is used for tomp titles.
Handwritten manuscripts for subtitles, end titles, etc.
A top title target is introduced into the device at the beginning of shooting, and the top title target is captured in the first frame of the film (second

After all predetermined subjects have been photographed, the end title target is generally photographed to complete the photographing of one roll of microfilm. However, such photographing work requires time and effort to prepare the various targets mentioned above (
Especially if handwriting is not possible), it is troublesome. Once a target has been produced, it requires space to store it for reuse, and it is difficult to classify and manage it.

The present invention solves problems such as No. 111, blip,
This type of camera device is designed to be able to capture and process frame numbers, targets, and other desired characters in any format and layout.
J! (Comprising a scanner device that performs main scanning exposure by writing on the film surface while the film is running for image slint exposure, using the film running as a sub-scanning;
The gist of this paper is a rotary microfilm camera device characterized by the following features.

4 and 5 show one embodiment, in which 15 is a character display device, 16 is a keyboard section including a character generator, and 17 is a character display section. Various types of display devices are known, such as CRT type and liquid crystal type, and are used, for example, in word processors and computer terminal devices, and arbitrary characters, figures, etc. can be displayed on the display section 17 by key operations on the keyboard 16. It can be created and displayed in any form on any surface position. Alternatively, it is also possible to call up and display display contents such as characters and figures recorded in advance on the a-tuppy 18 with an extremely simple key operation. The present invention utilizes such a display device as a character display device by electrically connecting it to a rotary microfilm camera device using a cable 19, or by using it as a character display device.
is a scanner device built into the camera device side, and this example includes a laser unit (21) and a scanner unit 2, which are known per se.
This is a laser beam scanning system consisting of 2.

Then, key operations on the keyboard 16 of the character display device 15, ie, information creation key operations, are used to print out a desired character, fist symbol, figure, or text, and the placement information, such as position designation and position movement, is displayed on the display surface. By using the film frame range image C' displayed as a guide, desired characters such as blip frame numbers etc. are created and displayed on the display unit 17 in the desired format and layout B-N, and the control circuit ( CPU) 23 inputs f and Q.

Next, the original O is introduced into the camera device, and when the sensor 31 detects that the leading edge of the original 0 has reached the illumination unit 7, the slit n light of the developed image is started to be applied to the film 12 as described above. At the same time, the signal from the sensor 31 is input to the control circuit 23 on the character display device side, and according to the format and layout of the character inputted in advance to the control circuit 23, the document image exposure section S by the slit 13 and the document image exposure part S by the laser are input. A character generation signal is sent to the character generator 25 at a timing that takes into account the time taken for the film 12 to move between the writing section and the writing section. The character generator 25 sends the main scanning signal of the character generated at the timing when the film movement speed is set to the sub-scanning to the laser unit l-21 and the scanner unit 22.
Output to.

The laser unit 21 and scanner unit 22 driven by the above (g) write the output pattern of the character generator on the film 1.
During the traveling process, the second side receives sequential slit exposure of the original image in the original image exposure section S, and then a laser writing section writes characters C in the desired format and layout previously created and input on the display device 15. The characters C-N are photographed on the film surface by the writing scanning exposure of -N.

Characters other than blip C and frame number N, such as various targets such as shooting date, operator name, top title, etc., can be similarly imaged onto the film 12 in a desired format and layout.

By creating various formats and layouts for various characters in advance and storing them on the floppy 18, you can recall and use what you need with a very simple keystroke, making it easy to create characters each time. No operations are required, making the shooting process easier and faster.

Storing a floppy 18 requires almost no space.

By equipping the display device with a video interface and video memory, it can also be used as a COM. In FIG. 6, 26 is an interface when used as a COM, and 27 is a shutter drive circuit.

As the scanner device 420, in addition to the laser beam scanning system shown in the illustrated example, a scanning exposure device using an LED array or the like can be used.
