PURPOSE:To switch and display both of timer data and name and date data on a specific person through a simple switching means. CONSTITUTION:Time and date information obtained by a timer counting circuit 3 is passed through an AND circuit 4 and a decoder 5 and displayed on a timer information display device 6a. When a display changeover switch S1 is operated, the timer display is changed into a specific person information display and the operation signal is inputted to a one-shot circuit 7, which outputs a pulse signal to invert the output state of an FF9, thereby releasing AND circuits 18 and 19 from gating operation. When the contents of a selecting circuit 11 are set to, for example, a, information of a name, an age, etc., stored in the 1st specific person information storage part 14 is outputted to a decoder 19 through the circuit 18 and then displayed 20. Then, pieces of birthday information in the 1st-the 3rd birthday storage parts 14c-16c and data information from a data counting circuit 3b are inputted to corresponding coincidence circuits 23-25; when data coincidences are detected, coincidence signals f1-f3 are supplied to corresponding age storage parts 14b-16c to increase age information by one, thus updating the age. |
