A coordinate input device, which detects a signal outputted from a coordinate input pen on the surface of a tablet and converts it into coordinate data, is provided with: a phase-control circuit for shifting the phase of an ac signal from the device main body and for outputting the resulting signal to the coordinate input pen; a Sense Amp circuit for amplifying the ac signal with its phase changed that was outputted from the coordinate input pen and has been detected on the tablet surface; a phase-difference detection circuit for detecting the phase difference between the signal amplified by the Sense Amp circuit and the ac signal from the device main body; and a color conversion circuit for outputting, together with coordinate data, a specific piece of color information that corresponds to the phase difference that has been detected by the phase-difference detection circuit from pieces of color information that have been preliminarily stored in association with phase differences.

Coordinate input device and a program-recording medium for use in such a

A word processing system operates either in a normal display mode or in a layout display mode. In the normal display mode, characters are displayed on a display screen in a size suited for recognizing the contents. In the layout display mode, a full page layout is displayed through the use of symbols which are smaller than the characters in the normal display mode. In a preferred mode, 2.times.3 character positions are included in a block which corresponds to one character size of the normal display mode.
