Claims

[Scope of utility model registration request]

In a two-dimensional coordinate counting device that detects a pulse corresponding to two-dimensional coordinates output from an input device as a coordinate position,
A latch circuit that temporarily stores a signal from an input device, an edge detection circuit that detects an edge of a signal from an output signal of the latch circuit, and an up/down counter that counts up and down based on the output signal of the edge detection circuit. A two-dimensional coordinate counting device comprising:
