Abstract
A sensor unit includes a light-emitting unit including a light-emitting element configured to emit light, a light-receiving unit including a light-receiving element configured to receive the light emitted from the light-emitting element, a flag configured to pass through a space between the light-emitting unit and the light-receiving unit, and a board, wherein a cutout or a hole is formed in the board, wherein the light-emitting unit and the light-receiving unit are mounted on the mounting surface of the board so that the light-emitting element and the light-receiving element face each other, and the light emitted from the light-emitting element travels straight along the mounting surface of the board over the cutout or the hole, and wherein the flag moves in a direction intersecting the mounting surface of the board and enters the cutout or the hole, thereby blocking the light traveling from the light-emitting element to the light-receiving element.
