CONSTITUTION:Photoelectric light emitting elements 8 and 9 of a left and right light-projecting body 6 and 7 are successively lit at constant time intervals from the external end side toward the center portion with a scanning lighting driving circuit 5 to project light toward the lower light-receiving bodies 11 and 12, so that the quantity of light according to the number 'n' of elements 8 and 9 which are not shielded with a cloth or sheet 1 is input to an amplifying substrate 13 from light-receiving bodies 11, 12 to output a voltage signal proportional to the quantity of light. This voltage signal is introduced into a control device B, followed by the comparison of the size of the output data under a total incident light condition where no cloth or sheet 1 stored in advance exists, it is decided that there exists a cloth or sheet 1 when a detecting voltage is smaller. The position of an edge can be detected by the detection of the number of the elements 8 and 9 shortly before being shielded with an edge of a cloth or sheet 1, so that the width of the cloth or sheet 1 can be accurately detected.
