Abstract
PURPOSE:To reduce the size of an IC and to decrease power consumption, in carry operations, correcting operations, and mode changing operations, by changing the display contents by fine continuous movement by the use of a shift register at the time specified digits or whole digits are moved. CONSTITUTION:Under the normal state, a second counter 3, a minute counter 4, and an hour counter 5 sequentially perform time counting operations, and the counted contents are outputted to a mode changing circuit 8. The numbers of digits selected by a digit signal D froma digit signal generator 14 are read out of a character memory device 31, stored in display registers 32a-32f, and displayed on a dot matrix display device 37 via a segment driver 35. Since the contents of the shift register in the display register 32, wherein character patterns are stored, and sequentially replaced by the new contents at the time of the carrying operations, the correcting operations, and the mode changing operations the display on the display device 37 is replaced by the new contents by the fine continuous movement.
