JPS59185315A - Focusing device of optical apparatus - Google Patents

Abstract

PURPOSE:To prevent a motor from runaway or damage by switching focusing operation status by using an electric switch. CONSTITUTION:An output signal of an AF detecting means A and an output signal of a manual operation switch B are selected and inputted by a signal selecting means C consising of digital switched C1-C3. The means C outputs the output signal of the means A usually, and when the output signal of the means B is inputted, outputs the output signal of the means B with priority in stead of the output signal of the means A. The output of the selecting means C is supplied to a motor driving means D. When the motor M is to execute focusing operation by the output of the means A, the motor M is driven on the basis of the output of the means A and a focus lens L is delivered to a focusing position to execute focusing.
