Abstract

PURPOSE: To achieve the simplification of constitution and handling by using a nonvolatile memory.
CONSTITUTION: While the quantity of the light exposed is being measured, the various constants necessary for computing the optimum exposure are stored in a nonvolatile memory and are made freely rewritable according to need. The code numbers given, data by data, are inputted by utilizing the digital switch which inputs expected exposure value and is provided on the surface panel of the control machine, after which the data to be written are inputted and stored in the nonvolatile memory, then the writing may be accomplished without performing any laborious operation such as fetching out of the stored data by removing the cover of the housing and the readout of the data may be readily performed by programs.
