PURPOSE:To obtain a double picture in a video camera by covering a light source with a light shielding cover consisting of an inner and an outer cylinder while one is fixed and the other is rotatable, and rotating the outer movable cylinder by a sliding rack with a knob. CONSTITUTION:The light source 14 for irradiating subject video suppliers 12 and 12' is provided in a housing 1 and this light source 14 is covered with the light shielding cover 17 consisting of the inner fixed cylinder 15 and outer movable cylinder 16. The rack 22 is moved forth and back by the 1st knob 21 provided near the outer cylinder 16 to rotate the outer cylinder through a pinion 23. When an A-side projection hole 18 made in the outer cylinder 16 is aligned to a B-side projection hole 19' made in the inner cylinder 15, only the B-side video supplier 12' is lighted and when a B-side projection hole 19 of the outer cylinder 16 is aligned to an A-side projection hole 18' of the inner cylinder 15, the A-side video supplier 12 is lighted; and both A and B video suppliers 12 and 12' are lighted in an intermediate state. |
