Abstract

PURPOSE: To make an electronic apparatus small-size by setting the keyboard of a portable electronic desk calculator, etc., to a non-exposure state when the user carries it with himself and by switching the clock mode to the calculation mode or the time set mode when the keyboard is set to an exposure state.
CONSTITUTION: When cover C of a small-size electronic apparatus such as a portable electronic desk calculator is closed, time display on display equipment D can be read through read hole H; and when cover C is put on keyboard KB, keyboard KB is set to a non-exposure state. When keyboard KB is opened, the electronic apparatus is switched from the clock mode to the calculation mode or the time set mode while interlocking with cover C. Digital circuit technique is used to constitute a switch, which is operated according to switching of cover C, and switching of the switch responding to a switch signal, thus making the electronic appartus small- size and facilitating operations.
