Abstract

PURPOSE:To obtain an electronic clock fitted with time information storing function easy to use as a time table by enabling to call out the time information the nearest the current time among stored plural time information. CONSTITUTION:When C key is pressed in a matrix key circuit 224, a singnal 225 output from switch decoder reduced to 1 level and a comparing curcuit 219 operater. Pulrtal time information data read out of a register group for storing time information are stored in a latch circuit 217 through a read out circuit 215 and compared with the current time data read out of RAM 206 in the comparing circuit 219 and the time information the nearest the current time is written to a latch 227. Then, the time is transferred to a display circuit 223 and displayed.
