Abstract

PURPOSE:To photograph original plate films to be inspected regardless of whether they are a transmission or reflection type by providing a light source below an original rack where an original plate film is arranged and to a moving rack for cameras and providing at least one TV camera with a moving mechanism whose position is adjusted with a knob, etc., in addition to a fine adjusting mechanism. CONSTITUTION:One camera 32 is provided with an X-Y directional fine adjusting mechanism and the position of the camera 32 to a camera 30 is finely adjustable. The position relation between the cameras 30 and 32 when, specially, transmission type original plate films are inspected is adjusted by this fine adjusting mechanism and images of the two original plate films 2 and 4 mounted at accurate positions are displayed on a TV monitor accurately one over the other. The moving mechanism which moves the camera 32 in the X and Y directions is provided in addition to the fine adjusting mechanism and the camera 32 is moved in the X and Y directions through this moving mechanism by rotating movement knobs 38 and 40. This moving mechanism is specially for the inspection of reflection type original plate films.

One of the cameras 32 is provided with a fine adjustment mechanism in the X and Y directions (-), which allows the position of the camera 32 relative to the camera 30 to be finely adjusted. The adjustment mechanism adjusts the position between the cameras 30 and 32, especially when inspecting the transparent original film 11.
The images of the two original films 2.4 placed on it M are accurately superimposed and displayed on a TV monitor.

Separately from this fine adjustment mechanism, a moving mechanism is provided for moving the camera 32 in the X and Y directions, and the moving mechanism moves the camera 32 in the X and Y directions by rotating the moving knobs 38 and 40. is moved. This moving mechanism is especially intended for inspection of reflective master films. That is, in the case of a reflective original film, especially an eye-printed original film, the expansion and contraction during development is noticeable, and therefore, there are cases where there is a large difference in the expansion and contraction of the two original films 2.49. (1) Two originals - the center of the film is placed in the camera 30
.. 32, it may be placed at the correct (f/ position (-)) and the surrounding area may be photographed at a different position. When inspecting the plate, if you look at the TV monitor and see that the two images are out of sync, turn the knob 38.4.
After adjusting the two images so that they overlap by rotating and adjusting 0, I will write the plate inspection work.

Therefore, the movement by this knob 38.40 is activated only when at least one of the selection switches 6.8 (described later) is set to the reflection side, and when both are set to the transmission side, the adjustment is made by the fine adjustment mechanism described above. The position of the camera 32 is automatically adjusted to 11'/fJ.

That is, in the case of reflection, the light source 70.72 on the l- side is selectively turned on, and in the case of transmission, the lower light source 16.18 is selectively turned on. The two switches 6.8 can be switched between J4 transmission and reflection at any time on the left cloth, so even if the original film for reflection and transmission is placed on the mount 10.12, the inspection will not be possible. It is possible.
