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".
Claims31
A time set apparatus for an electronic clock comprising:
- hour switch means for generating twelve kinds of hour data
- minute switch means for generating plural kinds of minute data;
- time set and display means, coupled to said hour switch means and to said minute switch means for displaying a time determined by said hour and minute data resulting from manipulation of said hour and minute switch means;
- interpolation means, coupled to said minute switch means and to said time set and display means for interpolating a time-set interval between one kind of said minute data and another kind thereof which is adjacent to said one kind of minute data, and for generating interpolation data indicating how many times said minute data is generated, the time displayed by said display means being modified according to said interpolation data so that an interpolated minute display is performed.
