An automatic focussing apparatus having a plurality of sensors of the signal accumulation type includes a plurality of accumulation-type sensor sections for respectively receiving light from different object areas. Each sensor section produces, in response to a first signal, a signal which is variable in accordance with an amount of light received thereby. The signal produced by each sensor section is independently output to a signal processing circuit through an output terminal portion in response to a second signal. A control circuit supplies the first signal to each sensor section substantially at the same time, and monitors a signal producing state of each sensor section independently. The control circuit then supplies the second signal to the sensor section which reaches a predetermined monitoring state.
