Abstract

A touching detection device ( 1 ) includes: a probe ( 10 ) having a touched part ( 11 ) with a touch surface ( 11 a, 11 b ) to be touched by an object to be detected, a support part ( 13 ) supporting the touched part ( 11 ), and a sensed part ( 19 ); a sensor (S) sensing the sensed part ( 19 ); and a body ( 2 ) holding the probe ( 10 ) and the sensor (S). The support part ( 13 ) is held by the body ( 2 ) to be swingable in a direction in which the object to be detected touches the touch surface ( 11 a, 11 b ) of the touched part ( 11 ). The sensed part ( 19 ) is displaced in accordance with the amount of swing of the support part ( 13 ). The sensor (S) senses the sensed part ( 19 ) and outputs a detection signal when the sensed part ( 19 ) is displaced by a preset displacement amount. The support part ( 13 ) supports the touched part ( 11 ) via an angle adjustment mechanism ( 15 ) configured to be able to adjust the angle of the touch surface ( 11 a, 11 b ) in the swinging direction of the support part ( 13 ).

First claim

The invention claimed is:

1. A touching detection device comprising:
a probe having a touched part, a support part supporting the touched part, and a sensed part, the touched part having a touch surface to be touched by an object to be detected;
a sensor sensing the sensed part of the probe; and
a body holding the probe and the sensor,
wherein:
the support part is held by the body to be swingable in a direction in which the object to be detected touches the touch surface of the touched part;
the sensed part is configured to be displaced in accordance with an amount of swing of the support part;
the sensor is configured to, when the sensed part is displaced by a preset displacement amount, sense the sensed part and output a detection signal;
the support part is configured to support the touched part via an angle adjustment mechanism configured to be able to adjust an angle of the touch surface in a swinging direction of the support part;
the touched part has two touch surfaces to be touched by the object to be detected, the touch surfaces being perpendicular to each other;
both the touch surfaces are flat;
the support part is held by the body to be swingable in each of two directions in which the object to be detected touches each of the touch surfaces of the touched part;
the sensed part is configured to be displaced in accordance with an amount of swing of the support part in each of the two directions;
the sensor is configured to, when the sensed part is displaced by a preset displacement amount in accordance with the amount of swing of the support part in each of the two directions, sense the sensed part and output a detection signal; and
the angle adjustment mechanism is configured to be able to adjust an angle of each of the touch surfaces in a corresponding swinging direction of the support part.

2. The touching detection device of claim 1 , further comprising an adjustment jig detachably attached to the body to tilt the support part in the swinging direction of the support part.

3. A touching detection device comprising:
a probe having a touched part, a support part integrally coupled to the touched part, and a sensed part, the touched part having a touch surface to be touched by an object to be detected;
a sensor sensing the sensed part of the probe; and
a body holding the probe and the sensor,
wherein:
the support part is held by the body to be swingable in a direction in which the object to be detected touches the touch surface of the touched part;
the sensed part is configured to be displaced in accordance with an amount of swing of the support part;
the sensor is configured to, when the sensed part is displaced by a preset displacement amount, sense the sensed part and output a detection signal;
the touched part is coupled to the support part such that, when the support part is swung to an angle at which the sensor outputs the detection signal, the touch surface of the touched part is perpendicular to a touching direction of the object to be detected; and
the touch surface is flat and inclined to both the touching direction and a direction that is perpendicular to the touching direction before the support part is swung to the angle at which the sensor outputs the detection signal.

4. The touching detection device of claim 3 , wherein:
the touched part has two touch surfaces to be touched by the object to be detected, the touch surfaces being perpendicular to each other;
the support part is held by the body to be swingable in each of two directions in which the object to be detected touches each of the touch surfaces of the touched part;
the sensed part is configured to be displaced in accordance with an amount of swing of the support part in each of the two directions;
the sensor is configured to, when the sensed part is displaced by a preset displacement amount in accordance with the amount of swing of the support part in each of the two directions, sense the sensed part and output a detection signal; and
the touched part is coupled to the support part such that, when the support part is swung, in each of two swinging directions, to an angle at which the sensor outputs the detection signal, a corresponding touch surface of the touched part is perpendicular to a touching direction of the object to be detected.
