That is, when writing, for example, when you want to add a title to a required image (in this case, remove the unit type slide projector 48 in advance), first insert the required image into the A-side loading frame 13. Load the subject image supply bodies 12', each of which has a title written on the surface of a glass plate with a black backside to be described later, into the B-side loading frame, turn on the power switch 52, and turn on the light source. 14, then move the first knob 21 to the intermediate position to illuminate the AB both side subject image supply units 12, 12', and move the second knob 28 to the front end position to turn on the AB both side shutters 30, By leaving 30' open, an image with a title can be captured on the video camera. In this case, if you want to obtain only an image without a title, or if you want to check the condition of only the same image, move the first knob 21 to the rear end position and turn only the A-side subject image supply unit 12. Either turn on the light, or move the second knob 28 to the rear end position to shut off the B-side shutter 30'.In the same case, if you only want to see the tone of the title, turn the first knob 21. Move it to the front end position B
If only the side subject image supply unit 12' is illuminated, or if the second knob 28 is at the front end position and the third knob 34 is moved to the left end position, the A side shutter 30 is turned off. good. Furthermore, for example, when it is desired to obtain an image in which two types of images overlap, two types of subject image supply bodies 12, 1 are used.
2' into the loading slots 13 and 13' on each side of A and B separately, and then perform the same operations as when obtaining the image with the title above, and also create an image that combines the two types of images into halves. When you want to achieve a fade effect (wipe operation), you can set the second knob 28 to the intermediate position, and when you want to obtain a further fade effect, gently move the first knob 21 forward or backward from the intermediate position to perform a B-side throw. The amount of light may be adjusted by gradually bringing the light hole or the A-side light projection hole into a so-called chipped state.

In addition, various images can be obtained by devising other methods.
