Abstract

762,024. Indicating-apparatus. GOSSEN & CO., GES., P. May 19, 1954 [May 19, 1953; June 20, 1953], No. 14698/54. Class 106 (4). [Also in Group XX] Indicating-apparatus comprises a roller turned by a knob 204 to cause the index mark 203, Fig. 1, or the point of a helical line 102a, Fig. 2, which is exposed through a slot, to follow the pointer 1a of an exposure meter at the same time turning a further roller to associate appropriate values on diaphragm opening and shutter speed scales. The speed scale is stationary and the opening scale may be carried by the further roller as in Fig. 1 or the opening scale may also be stationary, the association being indicated by lines 220 on the further roller as in Fig. 2. The follow-up device is used for adjusting a camera in accordance with the scale readings (see Group XX).
