ABSTRACT:
A time set apparatus includes twelve hour set switch keys and twelve minute set switch keys. Each of the hour set switch keys designates one of 1 o'clock to 12 o'clock. Each of the minute set switch keys designates one of 0, 5, 10, . . . 50 and 55 minutes. The minute set switches are coupled to an interpolation circuit. The interpolation circuit counts how many times any one of the minute switch keys is depressed, and generates an interpolation data. When 10 o'clock key and 30 minute key is once depressed and then the 30 minute key is further depressed by three times, the interpolation data indicates "3" and the set time becomes "10:33".
