Abstract

An electric power tool includes: an output shaft on which a front-end tool is adapted to be mounted; and a power transmission mechanism that transmits a rotational output of a motor to the output shaft. A posture information acquisition unit acquires posture information for identifying a posture of the electric power tool. A torque information acquisition unit acquires torque information indicating a measured value of tightening torque produced by the front-end tool. A transmission unit transmits the posture information, the torque information, and time information related to a time when respective information is acquired to an external apparatus.

First claim

The invention claimed is:

1. An electric power tool comprising:
a main body that includes:
an output shaft on which a front-end tool is adapted to be mounted;
a power transmission mechanism that transmits a rotational output of a driving source to the output shaft;
a posture information acquisition unit that acquires posture information for identifying a posture of the electric power tool;
a torque information acquisition unit that acquires torque information indicating a measured value of tightening torque produced by the front-end tool;
a transmission unit that transmits the posture information, the torque information, and time information related to a time when the respective information is acquired, to an external apparatus;
a reception unit that receives recommendation information generated based on the posture information, the torque information, and the time information; and
a notification interface that communicates the recommendation information received,
wherein the recommendation information is a type of the electric power tool suited to a content of work or an optimum value of an operation parameter in the electric power tool being used.

2. The electric power tool according to claim 1 , comprising:
a battery that supplies electric power to the driving source; and
a battery information acquisition unit that acquires battery information indicating a status of the battery, wherein
the transmission unit transmits the battery information and time information related to a time when the battery information is acquired to the external apparatus.

3. The electric power tool according to claim 1 , comprising:
a drive restriction unit that restricts the driving source from being driven while the recommendation information is being communicated by the notification interface.

4. A processing apparatus comprising:
an information acquisition unit that acquires posture information for identifying a posture of an electric power tool, torque information indicating a measured value of tightening torque, and time information related to a time when the torque information and the posture information are acquired in the electric power tool;
an estimation unit that estimates a content of work in which the electric power tool is used, based on the posture information, the torque information, and the time information; and
an information generation unit that generates recommendation information adapted to the content of work estimated, wherein
the recommendation information is a type of the electric power tool suited to the content of work or an optimum value of an operation parameter in the electric power tool being used.

5. The processing apparatus according to claim 4 , further comprising:
a transmission unit that transmits the recommendation information to the electric power tool or a terminal apparatus associated with the electric power tool.

6. The processing apparatus according to claim 4 , further comprising:
a notification interface that communicates the recommendation information.

7. The processing apparatus according to claim 6 , wherein
the processing apparatus is mounted in the electric power tool, and
the processing apparatus further comprising a drive restriction unit that restricts a driving source in the electric power tool from being driven while the recommendation information is being communicated by the notification interface.
