To attain a simple constitution and energy saving by devising the supply mode of power supply for driving luminous elements, in electronic having the luminous element.

This electronic equipment, provided with luminous elements 4 operated as required in response to personal operation and used as an indicator of operational information, illumination or the like, has an automatic power- off circuit 7 executing an automatic power-off operation which cuts off power supply from utility power if personal operation is not conducted over a prescribed time, and is formed so as to drive the luminous elements 4 by utilizing the power supply supplying power to the automatic power-off circuit 7. It is thus possible to eliminate an exclusive driving circuit to drive the luminous element 4 and cut the power needed to drive the luminous elements 4.
