CN2240161Y - Timing calculator capable of removing word key display - Google Patents

Abstract

The utility model relates to a timing calculator which is capable of removing word key display. The surface part of a word key switch is designed into a display-typed liquid crystal plate which is composed of longitudinal (SEG) and transverse (COM) quadrillage circuit lines which are connected together. A start-stop key triggers a central processing unit (CPU), and the quadrillage circuit lines can prompt the liquid crystal plate to display word key symbols and positions. When the word key is pressed, the central processing unit detects whether the liquid crystal plate of the word key is opened or not to determine on executing the operating command or not; when the word key is not opened or opened within the set time, the central processing unit automatically closes the word key display and converts the word key display into the time display, so that the user can clearly scan the time.
