Title:
EXPOSURE METER
Document Type and Number:
Japanese Patent JPS5681430
Kind Code:
A
Abstract:

PURPOSE: To enable digital indication of exposure informations by a smaller unit than IEV and in a form easy to read by using an indicating member for integer- term figures and an indicating member for decimal-term figures in an apex-type indication.

CONSTITUTION: A digital signal obtained through the operation 9 of the photometry output of a photoelectric transducing circuit 1 and the setting of the sensivity of a film of a circuit 8 is converted in a mark 10 and supplied to a digital indication part 11. In the indication part 11, the integer term in the digital output whose unit is the IEV in the apex-type indication is indicated by figures by using, at least, two figure indicating members, while an indicating member exclusively used for the decimal term is also provided. Thus, the indication of the exposure informations is performed by combining the indication by the indicating member for the part of the integer with and the indication by the indicating member for the part of the decimal.
