Claims

[Claims for Utility Model Registration] Consisting of a constant force device, a digital hardness meter, and a computing unit, the digital hardness meter is driven up and down by a motor via the arm of the constant force device, and the digital hardness meter A stop switch is provided to set the initial position and measurement position of the meter, and a driving current is applied to the motor in accordance with a signal from the arithmetic unit, and the driving current is turned off in response to a signal from the stop switch. The arithmetic unit supplies a command signal to the motor, and after a certain period of time has elapsed, supplies a reverse command signal to the motor again, while the input signal is input to the hardness data input section. An automatic hardness measuring device characterized in that the hardness data is supplied to an acquisition section, is superimposed with a delay pulse from a timing adjustment circuit, and is taken out for each set time and stored in a memory circuit.
