Abstract

PURPOSE:To reduce the power consumption by providing a control means for setting the other indicator to a non-operating state, when the indicator whose priority is the highest in plural indicators is set to a displayable state, and also, setting the indicator whose priority is high next to said indicator to a display state, when the indicator being in an operating state is set to a non- operating state. CONSTITUTION:A CPU 4 stops a power source supply of an indicator and sets it to a non-operating state as a control means, when an indicator whose priority is the highest in the indicators 7, 8 is set to a displayable state. Subsequently, when the power source supply to the indicator 7 being in an operating state is stopped and it is set to a non-operating state, the power source supply is executed to the indicator 8 whose priority is high next to said indicator and it is set to a display state. Also, the CPU 4 detects an attached or detached state of the indicator 7 through a port P0, and detects a grade of the indicator 7 through ports P1, P2. In such a way, the power consumption can be reduced.

Description

【発明の詳細な説明】 ［産業上の利用分野］ 本発明は複数の表示器を有する電子機器に関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electronic device having a plurality of displays.

とする。[Means for Solving the Problems] In order to achieve such an object, the present invention provides an electronic device having a plurality of displays, in which the display with the highest priority among the plurality of displays is displayed. When using the Possibility 7 method, if other display devices are set to non-operation state, and a display device that is in an active state is set to a non-operation state, the display device with the next highest priority after that display device is set to a display state. It is characterized by comprising a control means.
