Abstract

PURPOSE:To enable preventing of the occurrence of malfunction through the removal of a spike noise, by constituting a device such that a pluse width of a gate signal is narrower that of a projecting pulse, and the former is contained on the latter. CONSTITUTION:Light, reflected by an object, enters a collecting element 62, and is fed to a comparator through a collecting circuit, a coupling capacitor where a collecting signal is generated. The collecting signal i is gated at an AND circuit 36 by means of a gate signal u. The gate signal u is obtained from an OR circuit 41. Then, a t-point is always brought to HIGH, and an output of an inverter 53 is always brought to LOW, whereby an output g of the AND circuit 34 is generated from the OR circuit 41 as it is, and the output g produces the gate signal u. A signal, into which an oscillating output (a) is inverted, and a projecting pulse e are inputted to the AND circuit 34, and thereby the output g is generated in the latter half period.
