PROBLEM TO BE SOLVED: To restrain oscillation of a rotary type actuation lever securely and actuate a sensor securely and also prepare an actuator itself inexpensively and easily in a sensor actuation mechanism for actuating the sensor of a photo interrupter by the rotary type actuation lever. SOLUTION: A rotary type actuation lever 25 formed with synthetic resin material is turnably supported by a shaft 26 in a body case of a facsimile device and also a restraining part which serves as a pair of reinforce ribs 29 crossing substantially orthogonal with horizontal lever part 25b which has an actuation part 25c for actuating a photo interrupter 10 at its tip is disposed in a part of the body case and the actuation part 25c of the horizontal lever part 25b is securely approached to an angle groove shaped detecting part of the photo interrupter 10 by restraining oscillation of the horizontal lever part 25b by the restraining part. |
