<p>PURPOSE:To provide a watch of easy operation without using any switch by letting the coordinate reader provided to the watch be an input unit. CONSTITUTION:When the coordinate read face 1 formed on the glass face 2 of the watch is assigned with a light pen 3, the pulses corresponding to the coordinates are generated as an input signal by the induction coupling of the sense lines formed by a plurality of lines intersecting perpendicularly according to the coordinates provided to the back of the face 1, whereby processing according to the read of the required programs of RAM is accomplished, thus the correction of the year, month, date, minute, second, the assignment of AM, PM and displaying of various operations, etc. may be performed without using any switch. When patterns are drawn on the coordinate surface 1, displaying of required functions by interrupt programs or the like is accomplished, thus the watch of easy operation having no switches may be provided.</p> |
