<p>PURPOSE:To select and display the picture of a screen even from a moving place in a video projector device by fitting a coordinate detector to output a coordinate signal according to the wavelength of infrared rays at the upper part of the screen, and operating the coordinate detecting part by emitting the infrared rays by an operating key. CONSTITUTION:This device is provided with a console 2 for selecting the kind of the picture to be displayed on the screen 1, a projector controller 3 for projecting the corresponding picture on the screen according to a picture selection signal from the console 2, and a coordinate detector 4 fitted to the upper part of the screen 1 and outputting the coordinate signal according to the wavelength of the infrared rays 2b. The device is constituted of a signal or circuit 5 to output the signal to the projector controller 3 by the coordinate signal 2d from the coordinate detecting device 4 or the picture selection signal from the console 2, and a remote operating device 6 for emitting the infrared rays 2b by the operation of the operating key so as to operate the coordinate detecting part 4. Accordingly, the picture can be controlled selectively from the movable place other than the console.</p> |
