Abstract

To detect a motion of a hitting tool more precisely by a sensor, provided is a sensor device including: a base member configured to be mounted on a hitting tool via a fitting structure; a substrate joined to the base member; a sensor disposed on the substrate and configured to detect a motion of the hitting tool delivered via the base member and the substrate; a communication unit configured to transmit a detection result of the motion of the hitting tool to an external device; and an exterior member configured to cover the sensor and the communication unit.

First claim

The invention claimed is:

1. A sensor device comprising:
a fitting member independent from a hitting tool;
a base member configured to be mounted on the hitting tool via the fitting member;
a substrate joined to the base member;
a sensor disposed on the substrate and configured to detect a motion of the hitting tool delivered via the base member and the substrate;
a communication unit configured to transmit a detection result of the motion of the hitting tool to an external device;
an exterior member configured to cover the sensor and the communication unit,
wherein the fitting member includes a shape which is able to fit into a grip end of the hitting tool and corresponds to a shape of a fitting portion of the hitting tool,
wherein the base member is detachably mounted on the fitting member, and
wherein the base member further includes a lock mechanism that locks a positional relation between the base member and the fitting member when the base member is mounted on the fitting member;
an arm portion configured to be rotatable with respect to a portion facing the base member;
a claw formed in the arm portion and configured to engage with an inside portion of the grip end when the arm portion is rotated in a first direction; and
a protrusion formed in the arm portion and configured to come into contact with the base member when the base member is mounted on the fitting member, to rotate the arm portion in the first direction.

2. The sensor device according to claim 1 ,
wherein the base member is detachably mounted on the fitting member and is detachably mounted on a charger that has a shape corresponding to a mounting portion of the base member, and
wherein the sensor device further includes:
a battery case; and
a connection terminal configured to connect a battery accommodated in the battery case to a charging terminal of the charger when the base member is mounted on the charger.

3. The sensor device according to claim 2 ,
wherein the fitting member includes an octagonal pillar portion which is able to fit into the grip end, and
wherein the base member includes a cylindrical protrusion that fits into the octagonal pillar portion and a battery case internally included in the protrusion.

4. The sensor device according to claim 3 ,
wherein the base member comes into line contact or point contact with the fitting member.

5. The sensor device according to claim 1 , wherein the exterior member has a structure that protects the sensor and the communication unit from an external impact.

6. The sensor device according to claim 1 , wherein the base member and the substrate have materials and shapes that preserve frequency characteristics of delivered vibration of the hitting tool.

7. The sensor device according to claim 1 , wherein the sensor includes two sensors with mutually different detection directions.

8. The sensor device according to claim 7 , wherein the detection directions of the two sensors are orthogonal.

9. The sensor device according to claim 1 , wherein the base member and the exterior member are integrally formed.

10. The sensor device according to claim 1 ,
wherein the base member comes into line contact or point contact with the fitting member.

11. The sensor device according to claim 1 ,
wherein the fitting member has a shape capable of holding a shaft-shaped portion of the hitting tool, and
wherein the base member is mounted on the fitting member.

12. The sensor device according to claim 1 ,
wherein the fitting member and the base member have mutually corresponding shapes capable of holding a shaft-shaped portion of the hitting tool, and
wherein the base member is fitted on the hitting tool by holding the shaft-shaped portion between the base member and the fitting member.
