Abstract

An electric tool including: a motor configured to drive a front end tool; a control device configure to control rotation of the motor; a storage part configured to store a method of driving the motor by the control device; and a communication terminal to which a communication line for reading or writing information of the storage part is configured to be connected.

Claims (50)

1. An electric tool comprising:

a motor configured to drive a front end tool;

a control device configured to control rotation of the motor;

a communication terminal to which a communication line from exterior is configured to be connected, the communication terminal being connected to the control device;

a housing that accommodates the motor, and includes a battery holding portion;

a pair of connecting terminals provided at the battery holding portion and provided separately from the communication terminal; and

a battery that is configured to be detachably fixed to the battery holding portion and is configured to be electrically connected to the pair of connecting terminals when the battery is fixed to the housing,

wherein the communication terminal is provided at the battery holding portion, and

wherein the communication terminal is not connected to the battery when the battery is fixed to the housing.

2. The electric tool according to claim 1 , further comprising a storage part configured to store a method of driving the motor by the control device,

wherein the control device includes a microprocessor, and

wherein the method of driving the motor is determined according to at least one of a computer program and a control parameter stored in the storage part.

3. The electric tool according to claim 1 , wherein the communication terminal is provided at a portion which is exposed when the battery is removed from the battery holding portion, and

wherein a connection cable is configured to be connected to the communication terminal when the battery is removed.

4. The electric tool according to claim 3 , wherein the battery holding portion accommodates a circuit board to which the control device is mounted, and

wherein the communication terminal is connected to the circuit board.

5. The electric tool according to claim 1 , wherein a socket cover for closing an opening portion is provided at the opening portion of the communication terminal of the housing.

6. The electric tool according to claim 1 , wherein the communication terminal is connected to the control device.

7. The electric tool according to claim 1 , wherein the communication terminal is configured to be connected to a device other than the battery,

wherein when the battery is fixed to the battery holding portion, the battery covers the communication terminal to disable the communication terminal from being connected to the device other than the battery.

8. An electric tool comprising:

a motor configured to drive a front end tool;

a control device configured to control rotation of the motor;

a communication terminal to which a communication line from exterior is configured to be connected, the communication terminal being connected to the control device;

a housing that accommodates the motor;

a pair of connecting terminals provided at the battery holding portion and provided separately from the communication terminal; and

a battery that is configured to be detachably fixed to the housing and is configured to be electrically connected to the pair of connecting terminals when the battery is fixed to the housing,

wherein the housing includes a body portion that extends in a front-back direction, a handle portion that extends downward from the body portion in a downward direction, and a battery holding portion that is provided lower to the handle portion, the housing being divided into two members in a lateral direction which crosses the front-back direction and the downward direction,

wherein the communication terminal is provided at a divided surface of the two members of the body portion and a pair of connecting terminals of the battery are provided separately from the communication terminal; and

wherein the communication terminal is not connected to the battery when the battery is fixed to the housing.

9. The electric tool according to claim 8 , wherein a socket cover for closing an opening portion is provided at the opening portion of the communication terminal of the housing.

10. The electric tool according to claim 8 , further comprising a storage part configured to store a method of driving the motor by the control device,

wherein the control device includes a microprocessor,

wherein the method of driving the motor is determined according to at least one of a computer program and a control parameter stored in the storage part.

11. The electric tool according to claim 8 , wherein the communication terminal is connected to the control device.

12. An electric tool comprising:

a motor configured to drive a front end tool;

a control device configured to control rotation of the motor;

a communication terminal to which a communication line from exterior is configured to be connected, the communication terminal being connected to the control device;

a housing that accommodates the motor;

a pair of connecting terminals provided at the battery holding portion and provided separately from the communication terminal; and

a battery that is configured to be detachably fixed to the housing and is configured to be electrically connected to the pair of connecting terminals when the battery is fixed to the housing,

wherein the housing includes a body portion that extends in a front-back direction, a handle portion that extends downward from the body portion in a downward direction, and a battery holding portion that is provided lower to the handle portion, the housing being divided into two members in a lateral direction which crosses the front-back direction and the downward direction,

wherein the communication terminal is provided at an outer surface of one of the two members of the handle portion and a pair of connecting terminals of the battery are provided separately from the communication terminal; and

wherein the communication terminal is not connected to the battery when the battery is fixed to the housing.

13. The electric tool according to claim 12 , wherein a socket cover for closing an opening portion is provided at the opening portion of the communication terminal of the housing.

14. The electric tool according to claim 12 , further comprising a storage part configured to store a method of driving the motor by the control device,

wherein the control device includes a microprocessor,

wherein the method of driving the motor is determined according to at least one of a computer program and a control parameter stored in the storage part.

15. The electric tool according to claim 12 , wherein the communication terminal is connected to the control device.
