In an image pick-up device, a document, picture, OHP (Over Head Projector) film or similar subject is laid on a stage. While the subject is illuminated by a light source unit, the resulting imagewise reflection from the subject is picked up by a television camera and transformed to a video signal. The image represented by the video signal appears on a screen in a conference room or on the individual monitor in a communication conference. Light issuing from the light source unit and offensive to the eye is prevented from leaking to the outside of the device. This, coupled with the fact that irregularity in the illumination on the subject is reduced, insures a clear-cut image. Further, the device is easy to operate and protects the working environment from deterioration due to heat generated by the light source unit.
