Claims

[Scope of Claim for Utility Model Registration] (1) A photo interrupter in which a light emitting part and a light receiving part facing each other are installed upright on a rectangular parallelepiped case,
A bellows-like hook portion and a locking protrusion are integrally provided in the lower part of one side of the case, and an engaging protrusion is integrally provided in the lower part of the other side parallel to the side, thereby making it possible to use a copying machine, etc. A photo interrupter characterized in that a mounting portion is formed on the bracket, and further, the vertical center line of the other side surface perpendicular to the side surface is aligned with the vertical center line of the detecting section between the light emitting section and the light receiving section. (2) The photo interrupter according to claim 1, which is a registered utility model, characterized in that concave notches are provided at the lower centers of two other side faces perpendicular to the side face, respectively, so as to face each other.
