| 摘要 | 907,301. Photographic cameras with exposure meters. AGFA A.G. Nov. 14, 1958 [Nov. 23, 1957], No. 36757/58. Class 98 (1). A photographic camera having a built-in exposure meter with a follow-up pointer comprises a transmission mechanism connecting the follow-up pointer with the camera exposure setting means and film-sensitivity setting means, said mechanism comprising two members arranged for relative movement while in mutual engagement so that the two setting means are not operatively connected to each other. Two examples are given, illustrated by Figs. 3 and 4 respectively, in which the shutter 4 on objective mount 2 has coupled adjustment means for the aperture and the shutter speed. To adjust the shutter the rod 6 is moved longitudinally by means not shown in Fig. 3 and this movement is then transmitted through the segment 14 to a lever 17 the free end 17a of which moves a rack 18 and hence a pinion 19, a cam 20 and the follow-up pointer 21. This pointer can also be moved by rotating the film sensitivity device 8 which in turn rotates the shaft 6 and the segment 14. Considering Fig. 4, the control member 6 comprising two threaded members 6a, 6b is moved longitudinally when shutter 4 is adjusted and 6b moves rotatably and longitudinally, when the film sensitivity device knob 36 and cam pinion 34 is rotated. The lever 27 is then rotated against a spring 27 and the following pointer moves. The objective mount 2 is screwed on to the surface of the camera housing so that small adjustment displacements of the objective are possible. | ||
