<p>PURPOSE:To provide a photointerruter capable of excluding waste of natural resources that even normal elements are scrapped. CONSTITUTION:As shown in figure, the fixing part 3a of a light emitting element 1 is engaged with the fixing part 3b of a phototransistor 2 via an engaging part 3e, and a photointerrupter is constituted. When either one of the elements is damaged, the engament is released by sliding the engaging part 3e up and down. The damaged element is detached together with its fixing part. A fixing part having a new element of the same kind is engaged. Thereby an interrupter can be regenerated.</p> |
