源につながれた光源１６．１８が配置されている。As shown in detail in Fig. 1, the two film stands 10.12 on which the original film 2.4 is placed are made up of a light diffusing plate placed under a transparent glass plate, and the underside of the light diffusing plate is roughly transparent. A light source 16.18 connected to a DC stabilized power supply is arranged to illuminate the original film 2.4.

彰可能となっている。A movable camera frame 50 on which two TV cameras 30 and 32 are attached is arranged above the film frames 10 and 12, and this frame 50 is mounted on a Y-direction movable frame 48 that moves only in the Y direction. This allows the frame 50 to be moved freely in the X and Y directions on the film frame 10.12 manually using the handle 52. This allows two TV cameras 30
32 can highlight any corresponding position on the original film 2.4.

２の位置は自動調整されるように構成されている。Separately from this fine adjustment mechanism, a moving mechanism for moving the camera 32 in the X and Y directions is provided, and the moving mechanism moves the camera 32 in the X and Y directions by rotating the moving knobs 3B and 40. will be moved. This moving mechanism is especially used for inspection of reflective original films. That is, in the case of a reflective original film, especially an eye-printed original film, the expansion and contraction during development is large, and therefore, there is a large difference in the amount of expansion and contraction between the two original films 2.4. Furthermore, in the case of one original film or eye-printed film and the other original film or color separation film, the size of the image between the input original films often differs greatly. Therefore, even if the center of the two original films is placed at the correct position relative to the camera 30, 32, the surrounding areas may be photographed at different positions. In order to eliminate this inconvenience, when inspecting the original reflective film,
When the two images are out of alignment because they are photographed at slightly different positions when viewed on a TV monitor, the two images are adjusted by rotating the knobs 3B and 40 so that they overlap, and then plate inspection work is performed. Therefore, the movement using the knobs 38 and 40 is only activated when at least one of the selection switches 6 and 8 (see below) is set to the reflective side, and when both are set to the transmitting side, the adjustment is made using the fine adjustment mechanism. camera 3 in the position
The position of No. 2 is configured to be automatically adjusted.

とによりＴＶモニタの影像が正確に重なって映出される
ようになっれている。Generally speaking, in order to solve the problem of the difference in image size between input original films, TV cameras are equipped with a magnification adjustment mechanism that adjusts the magnification within a small range. The system is constructed so that the images can be input at different magnifications, and by adjusting this magnification adjustment mechanism, the images on the TV monitor can be displayed overlapping each other accurately.

ている。Furthermore, the TV camera 30.32 is provided with a filter 42.46 for properly photographing eye printing, printing plates, etc. In other words, it is difficult to take good pictures of eye-burning and printing plates because the image density is low, but it is difficult to photograph them in a color that is complementary to the color of the original film (yellow for eye-burning, and offset printing plates with thin edges). It is best to shoot through a magenta filter (if available), so
A plurality of filters 42, 46 are replaceably mounted.

72 is the original film 2 for reflection through mirrors 74 and 76.
．． Illuminate 4.
この光源７０．７２は前記光源１６．１８と同様に直流
安定化電源に接続されている。This light source 70.72, like the light source 16.18, is connected to a DC stabilized power supply.
そして透過、反射の選択スイッチ６及び、又は８を原版
フィルム２．４の種類に応じて選択する。Then, the transmission/reflection selection switch 6 and/or 8 is selected depending on the type of the original film 2.4.
即ちが反射の場合は上側のが光源７０．７２が選択点灯

る。That is, in the case of reflection, the upper light sources 70 and 72 are selectively turned on, and in the case of transmission, the lower light sources 16 and 18 are selectively turned on. Since the two Swiss switches 6.8 can be switched between transmission and reflection separately on the left and right sides, inspection can be performed even if the original films for reflection and transmission are respectively placed on the mounts 10.12.
