Claims

[Scope of utility model registration request]

In a digitizer that determines position coordinates by counting the number of clock pulses with a counter, a first memory stores an initial count value by the counter at the time of coordinate determination as a reference value, and a secondary count value is stored as a comparison value. Comparing means includes a second memory and a comparator for comparing the counted value stored in the second memory with the counted value stored in the first memory, and this comparing means When the comparison result exceeds two clock pulses (including two clock pulses), the comparison value is outputted as measurement data, and an update signal is outputted to write this comparison value into the first memory as a new reference value. digitizer.
