Abstract

PURPOSE:To supply power without connecting a power cord by receiving light from a projector by a photovoltaic device and charging a charging battery for the power supply mounted on the electronic equipment side by an output from the photovoltaic device. CONSTITUTION:A head 74 is moved along an X rail 64 and a Y rail 66, and can be shifted to an arbitrary position on a drawing board 62. A device 92 is also transferred along the Y rail 66 while being interlocked with movement along the Y rail 66 of the head 74, but a photosensor group for the device 92 holds the state in which the photosensor group is oppositely faced to the projection line of a projector 93, The device 92 outputs voltage by light energy from the projector 93, and the voltage is fed to a charging battery 98 and used as a power supply for a display unit 82.
