Abstract
PURPOSE: To instantaneously change indication over depending on a selected time system through a simple construction, by storing the forenoon and afternoon of 24 and 12hr time systems into a memory, selecting a content of the memory by external operation and controlling a time system changeover circuit.
CONSTITUTION: When present time is set by ten keys K, the time is initially set in a present time register CO by a 24hr system through 12-to-24hr system changeover curcuit TT1 independently of the setting operation of the ten keys K and the register CO counts time in the 24hr system. The forenoon or afternoon in the 24 or 12hr system is stored into a memory CP depending on the circulation output of a ring counter RC at each operation of a switch AM/PM. When the forenoon or afternoon of the 12hr system is stored into the memory, the 24hr-system time in the register CO is changed into 12hr-system time by a code generated by the code change section of a 12-to-24hr system changeover circuit TT2 and then indicated on a display unit DSP. Time indication can thus be optionally and instantaneously changed over to the 24 or 12hr system.
