Lens shutter type zoom lens camera

Abstract

Abstract PURPOSE:To vary a visual field, and also, to make an irradiation angle of a stroboscopic device variable by providing a cam groove for moving a variable power lens group and a light emitting tube, on a single movable plate which has been provided on the upper part of a finder optical system and the stroboscopic type, and allowing the cam plate to interlock with zooming. CONSTITUTION:A cam plate 53 is positioned on the upper part of a finder device 8 and a stroboscopic device 9 and slidable in the right and left directions, and the cam plate 53 is provided with a variable power cam groove 55 for the finder device 8, a parallax correcting cam groove 56, and a stroboscope can groove 57 for the stroboscopic device 9. On guide projections 66a-68a, driven pins 69-71 are provided vertically, respectively, and these driven pins are fitted to the variable power groove 55, the parallax correcting cam groove 56 and the stroboscope can groove 57, respectively. Accordingly, when the cam plate 53 moves to the right and left, a variable power lens frame 66, a deflection angle prism operating plate 67, and a stroboscope case 68 move forward and backward, respectively, in accordance with a shape of these cam grooves 55-57.
