Claims

[Scope of utility model registration request]

(1) A casing formed of a cover that covers a rotating part with a cutter attached to the tip and a part of which is movably supported by a spring, and a casing that is attached near the tip of the casing and is determined by the amount of relative displacement between the casing and the cover. A sensor that detects the distance between the sensor and the object to be cut, a sensor input/output circuit that outputs a voltage according to the distance between the sensor and the object to be cut,
a memory circuit that detects the distance when the cutter contacts the workpiece from the output of the sensor input/output circuit, converts it into a voltage, and stores it; A subtraction circuit that subtracts from the voltage when the cutter contacts the workpiece, a comparison circuit that inputs the output from the subtraction circuit and compares it with a set reference value, and the subtraction value corresponds to the required cutting depth. A cutting amount sizing device comprising: a stop circuit that issues a signal to stop cutting by the cutter when the output from the subtraction circuit reaches a reference value by reaching a predetermined value.

(2) Utility Model Registration Scope of Claims The cutting amount sizing device according to claim 1, in which the rotating part is formed by an air motor, and the stop circuit is formed by an air valve connected to the air source of the air motor. .

(3) Utility Model Registration Scope of Claims In the cutting amount sizing device according to claim 1, the rotating part is formed by an electric motor, and the stop circuit is formed by a relay switch connected to the power source of the electric motor. size device.
