Abstract

PURPOSE: To ensure clear display, while simplifying the construction, by controlling the respective segments of seven segment elements for display of 12 hours so that necessary items other than the time may be displayed.
CONSTITUTION: Seven segment elements are used and interchanged to display the hour and minute or the nimute and second of 12 hours. This display is used to display the hour and minute of the 12 hours, which are preset in a timer memory through a setting input unit and a decoder, so that the a.m. and p.m. are dispalyed by the segments a and c of the seven segment elements capable of displaying 1 of 10 o'clock, so that the 1 of the 10 o'clock is displayed by the segment b, and so that the set time is displayed in terms of colons 19g and 19h in accordance with the recognition of the ON and OFF of the time limit device. When the switch of the input unit is interchanged, the letters such as clock of the second display are displayed to make it possible to judge that the first display is the preset limit time. The seven segment element for the time display is used in addition so that the necessary items of the set time limit are clearly displayed. Thus, it is possible to provide a time limit setting display device having such simple construction.
