ABSTRACT:
A facsimile machine has various detection devices. One of the detection device detects a sheet medium. The detection device includes a reflection type sensor directly mounted on a control board. An actuator is pivotally movably supported in a main frame of the facsimile machine. The actuator has a pivot shaft portion, a first arm and a second arm those extending from the pivot shaft portion. A free end of the first arm is abuttable on the sheet medium. If sheet medium is transferred to a predetermined portion, an edge of the sheet urges the free end to angularly rotate the actuator. A free end of the second arm is provided with a reflection member. The angular movement of the actuator causes the reflection member to be brought into confrontation with the reflection type sensor so as to detect passage of the sheet medium. A regulation member is integrally provided to the reflection member. The regulation member is brought into contact with the control board because of the gravity of the actuator, so that a given distance is provided between the reflection member and the reflection type sensor in the confronting state therebetween. The other sensor device may detects moving phase of a movable member. To this effect, the free end of the first arm is abuttable on the movable member.
