The A-side shutter 30 moves left and right only on a line perpendicular to the A-side optical axis 6 (guidance mechanisms etc. are omitted).
When the slider 35 is positioned at the left end of the left-right portion 32 in the forward movement position 6, the A-side optical axis 6
When the road is blocked and positioned at the right end, the blocking is canceled, and when the slider 35 is located at the left end of the left-right section 32 and the forward-rearward movement plate 26 is moved backward, the slider 35 is tilted. The mirror 9 located on the B-side optical axis 6' is moved to the tip of the section 31 to eliminate the blockage of the A-side optical axis 6.
can be moved to an out-of-the-way location using a moving knob 38, and is attached to a portion of the top wall of the cabinet 1 that corresponds to the space 40 formed when the movable mirror 9 is moved to an out-of-the-way location. A hole 41 is opened, and a light source section 42 is inserted into this mounting hole 41.
A unit type slide projector 48 consisting of a film loading section 43, a color correction plate 44 loading section 45, an oblique mirror 46, a magnifying lens 47, etc.
The optical axis 49 is removably fixed so that it coincides with the B-side optical axis 6'.

In the figure, 51 is a power cord, 52 is a power on/off switch, 53 is a penetration hole for the first knob 21, 54 is a penetration hole for the second knob 28, and 55 is a penetration hole for the third knob 34.
56 is a penetration hole for the moving knob 38, 57
indicates a holding frame.

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 overlapping image of two types of images, 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.

Also, operate the moving knob 38 to move the B-side optical axis 6'.
After moving the mirror 9 on top to a place where it will not get in the way, the unit type slide projector 48 is fixed to the housing 1 through the mounting hole 41, and in this fixed state, the slide projector 48 is operated and the half mirror 7 is moved. It can also be used for purposes such as obtaining slide images on a video camera via a video camera.

Incidentally, the loading frame 59 of the different subject image supply body 12 shown in FIG. A reflective plate 64 with a mirror 63 attached to the inner surface is arranged outside the opening 61,
This reflector 64 is attached to the loading frame 59 using a hinge (not shown).
and a bifold arm 69, which is attached to the loading frame 5 so that it can be opened and closed at a semi-right angle.
Reference numeral 9 is used by being attached to the outside of the image entrances 10, 10' in the above embodiment. That is, the loading section 6
The object image supply body 12 may be inserted into the projection screen 6 and used in the same manner as in the above embodiment, or the projection screen 6 may be used without it.
2, an image produced by an 8mm projector is projected through a reflecting plate 64, and this projected image is used when the projected image is used as a source of video footage.

In addition, FIG. 8 shows that the back side of the transparent glass plate 71 is painted black (or dark color) by applying black (or dark color) paint.
A title 73 is arbitrarily written on the surface of the transparent glass plate 71.

The present invention has the practical effect of being able to obtain several types of images as described above on a video camera, etc. by operating the knobs and arbitrarily moving the A-side shutter and B-side shutter as described above. It is.
