COORDINATE INDICATOR

PROBLEM TO BE SOLVED: To provide a coordinate indicator capable of preventing an oscillation circuit from being operated when coordinate input work is not executed even if a detection pen is preserved in a state where a pen center is depressed, prolonging the life of a contact and extending the interval of maintenance/ inspection. SOLUTION: A piezoelectric element 7 is pressurized by using an operation for depressing the pen center at the time of inputting a coordinate and generated pulse voltage is set to be the reset signal of a timer circuit 42. The count value of the timer circuit 42 is always reset while coordinate input work continues and a transmission circuit 30 continues the operation. When coordinate input work terminates, the size of force does not change even in a state where the piezoelectric element 7 is pressurized, for example. Thus, the reset signal is no outputted. Then, the timer circuit 42 terminates the operation of the oscillation circuit 30 when it count up.
