PURPOSE:To minimize the shape of moving picture taking devices and, at the same time, to economize the electric power by effectively utilizing the light of the illuminant, by installing the illuminant so that it may move and, at the same time, by constituting the illuminant so that it may automatically locate its position as the projecting magnification changes. CONSTITUTION:An arm 5 which supports an illuminating lamp 2 and a reflector 6, is kept by a fixed arm 51 so that the arm 5 may slide, and constituted so that the location of the illuminating lamp 2 may be changed. Moreover, one end of a wire 24 is fixed to a wire pulley 22 and the other end is connected to the end face of the arm 5 which can slide, so that the illuminating lamp may automatically locate its position in conjunction with the variation of the projecting magnification. That is to say, for example, when moving pictures are taken at an 1/34 contraction ratio, the arm 5 automatically moves until it reaches a location where the index coincides with the front end of the fixed arm 51. In this way, the moving picture taking device can be minimized in shape and the light of the illuminating lamp can be utilized effectively within a range in which moving pictures can be taken. |
