In a light shielding device for a copying machine, the light shielding device includes a sensor for detecting the light and a drive means for moving the light shielding sheet forward and backward as appropriate and stopping the light shielding sheet at an edge of a document based on the output of the sensor, wherein the drive means is manually operable. 1. A light-shielding device for a copying machine, characterized in that a switching means for switching the state is provided, and a manual operation member that can be engaged only during manual operation is attached to the drive means. (2) The light shielding device for a copying machine according to claim 1, wherein the switching means is constituted by a switch that is linked to the engagement operation of the manual operation member with the drive means. (3) The manual operation member includes an operation knob movable between a manual operation position and a non-manual operation position, an engaging member provided at an end of the operation knob, and an engagement member provided on the drive means side. The operating knob is comprised of an engaged member that engages with the engaging member when the operating knob reaches the manual operating position, and a biasing member that biases the operating knob toward the non-manual operating position. A light shielding device for a copying machine according to claim 1 or 2 of the claimed utility model registration.
