Description

[Detailed explanation of the invention] This invention is a method of exposing multiple original images to a single photosensitive plate according to a predetermined layout according to instructions from a recording medium such as a paper tape on which various photographic data have been recorded in advance. The present invention relates to a recording device for creating trimming data used at the time of photographing in an automatic copying camera for plate making that creates a set duplicate image.

The method of arranging and printing multiple images on a single printed sheet is widely used in various publications and catalogs, but in this case, trimming the original image is an essential task, and automatic copying is not possible. When using the camera, I perform cropping as described below.

Fig. 1 is a diagram for explaining the conventional procedure for trimming when using an automatic copying camera. and a frame that supports the original picture rack 3 so as to be movable back and forth by a motor (not shown);
5 and 6 are light sources, 7 is a control device, and 8 is a monitor television.

In the photographing rack 1, a film 9 is suctioned and held at a photographing position with a film holder 10, and a mask device 11 whose opening can be adjusted is installed immediately in front of the film 9.

A lens 13 equipped with an aperture device 12 and a shutter 14 are mounted on the lens rack 2.

An original image holder 15, in which a plurality of original images (not shown) are loaded side by side, is attached to the original image rack 8 so as to be movable vertically and horizontally, and rotatable around a horizontal axis.

When trimming an original image, a focusing glass (not shown) is set in place of the film 9 on the photographing rack 1, and the original image is projected. In addition to adjusting the opening, the original picture rack 3 is moved forward and backward to obtain the desired trimming, and the original picture is moved and rotated appropriately, and the data is recorded on a recording medium using the control device 7.

This operation is performed for each original image.

To photograph, the film 9 is set in the same copying camera and the recording medium is read by the control device 7, and all the original images are automatically and correctly photographed in sequence according to a predetermined layout.

However, the above-mentioned method requires an automatic copying camera itself to record various data necessary for trimming each original image on a recording medium in advance. The drawback was that the operating efficiency of the camera was significantly reduced.

The purpose of the present invention is to provide a relatively simple device that can create a recording medium that controls the trimming of an original image when copying using the automatic copying camera, without using the same camera. It is something.

In any case, move the original image holder 69 so that the desired trimming is achieved, and use the rotary plate 54 if necessary.
is rotated to find the amount of movement (that is, X' and Y' and the amount of rotation).

Each of the aforementioned motors M ₁ to _{M 5} is a stepping motor, and the number of pulses applied to the motor, the amount of movement of the original image holder 69, the amount of rotation of the rotary plate 54, and the amount of movement of the mask plates 58, 62 are controlled. is configured to be a value uniquely determined by the rotation angle for each pulse of the corresponding motor and the lead of each screw shaft.

When moving each part, pulses applied to each motor are generated by the CPU 101 and sent to the motor drive unit 76 via the interface 104 to control the amount of rotation of each motor. , the amount of movement of each part can be calculated. That is, the amount of movement of each part can be determined as follows: amount of movement=number of applied pulses×amount of movement per pulse.

Then, at this time, the amount of movement of the original image holder 69, the amount of rotation of the rotary plate 54, and each mask plate 58, 62
The amount of movement becomes the data necessary for trimming the original image 73, and this data, the number of the original image 74 input from the PTR 103, and other data necessary for copying are both numerically converted in the CPU 101, and then transferred to the recording medium by the PTP 102. to be recorded.

By sequentially performing the above operations on all the original images 73, and inputting and controlling the recording on the recording medium to the automatic copying camera, a set of chopped image films according to the desired layout can be obtained in a short time. be able to.

Therefore, if the device of the present invention is used in combination with the above-mentioned automatic copying camera, the operating efficiency of the expensive camera can be significantly improved.

In addition, since the device of the present invention trims the original image 73 one point at a time, the device is small and can be manufactured at low cost.

The movement of each mask plate 58, 62, the movement of the original image holder 69, and the rotation of the rotary plate 54 are carried out by motors.
Manual operation may be used instead of _M1 to _M5 .

Further, in the embodiment, the mask device is mounted on a rotary plate 54.
Although the mask device is rotated by placing it on the original image holder, a rotation mechanism may be attached to the original image holder. Furthermore, in the examples, although the original picture is shown alone,
The same original image holder for a camera may be used to hold multiple original images. However, in this case, the moving distance of the original image holder becomes large, and the size of the trimming table 51 is also required to be large.

Note that original images 73 of various sizes can be loaded into the original image holder 69 by replacing the original image frame 72 as appropriate.
