Abstract
PURPOSE: To inform a photographer of the preset change of photographic information by feeding oscillatory means with the pulses, which are generated in accordance with the preset photographic information through a counter in response to the change-over of a switch thereby to generate a warining sound.
CONSTITUTION: When switches S5 and S1 are turned on in response to the operations of a sagety button and an operating button, the input of a NOR gate 20 is reduced to a low level, and a pulse generating circuit 40 generates pulses in response to the input of a high level through an inverter 26. The resultant pulses are fed through the gate 20 to a photographic mode presetting counter 14 to preset the photographic mode in accordance with the count-up of the counter 14. On the other hand, the output of the gate 20 is fed through an OR gate 58 and an AND gate 56 to a sound generator 53 to count up the counter 14 so that a warning sound is generated from the generator 53 each time the preset photographic mode is changed. Irrespective of no operating feelong by the mechanical click upon the presetting operation, the photographic mode can be preset with a satisfactory operability.
