Metal detector, handheld power tool comprising this metal detector, metal detection method, and metal detection program

A handheld power tool, comprising:

• a metal detector that detects metal contained in a target and is removably attached to a handheld power tool that is used to work on the target, the metal detector including:
• a mounting portion that is mounted on a distal end part of the handheld power tool;
• a detection signal acquisition unit configured to acquire a detection signal which changes according to a detection intensity of the metal contained in the target;
• a determination unit configured to determine a presence or absence of the metal on the basis of an acquisition result acquired by the detection signal acquisition unit;
• a display unit configured to display the presence or absence of the metal by turning on different lights;
• and a display control unit configured to control so as to switch a color of a light displayed on the display unit on the basis of a determination result from the determination unit,
• a distal end part to which the metal detector is mounted;
• a drive unit configured to rotationally drive a tip tool for working the target;
• and
• a drive control unit configured to control a drive of the drive unit.

A metal detection method that makes use of a metal detector that detects metal contained in a target and is removably attached to a distal end part of a handheld power tool that is used to work on the target, the method comprising:

• a detection signal acquisition step in which a detection signal acquisition unit of the metal detector acquires a detection signal that changes according to a detection intensity of the metal in the target;
• a determination step in which a determination unit of the metal detector determines a presence or absence of the metal on the basis of an acquisition result acquired by the detection signal acquisition unit;
• and
• a display control step in which a display control unit of the metal detector controls so as to switch a color of a light displayed on the display unit on the basis of a determination result by the determination unit.

A metal detection program that causes a computer to execute a metal detection method that makes use of a metal detector that is removably attached to a distal end part of a handheld power tool that will perform work inside a target, the method comprising:

• a detection signal acquisition step in which a detection signal acquisition unit of the metal detector acquires a detection signal that changes according to a detection intensity of the metal in the target;
• a determination step in which a determination unit of the metal detector determines the presence or absence of the metal on the basis of an acquisition result acquired by the detection signal acquisition unit;
• and
• a display control step in which a display control unit of the metal detector controls so as to switch a color of a light displayed on the display unit on the basis of a determination result by the determination unit.
