the tool includes a device notification unit configured to send a notification to an external device, and
the predetermined type of processing includes processing in which the tool-end control unit makes the device notification unit send the notification.
5. The tool system of claim 1 , wherein
the tool-end control unit is configured to, when finding that objects corresponding to the current work object identified by the identification unit have been changed from a first object into a second object requiring a different working process from the first object, change the reference working procedures from a first reference working procedure for the first object into a second reference working procedure for the second object.
6. The tool system of claim 5 , wherein
the tool-end control unit is configured to, when changing the reference working procedures from the first reference working procedure into the second reference working procedure, define the working process step for the current work object to be the first working process step according to the second reference working procedure.
7. The tool system of claim 1 , comprising:
a transmission unit configured to transmit a wireless signal; and
a reception unit configured to receive the wireless signal transmitted from the transmission unit, wherein
the tool includes either the transmission unit or the reception unit, and
the identification unit is configured to identify the current work object based on reception information about reception of the wireless signal at the reception unit.
8. The tool system of claim 1 , further comprising:
an image capturing unit provided for the tool and configured to generate a captured image; and
an image storage unit configured to store a plurality of reference images associated with the plurality of work objects, wherein
the identification unit includes an image processing unit configured to perform image processing by comparing the captured image generated by the image capturing unit with a plurality of reference images and identify an actually shot work object as the current work object, the actually shot work object being a work object, shot in the captured image, out of the plurality of work objects.
9. The tool system of claim 8 , wherein
the image storage unit and the image processing unit are provided for the tool.
10. The tool system of claim 8 , further comprising a processor provided with the image storage unit and the image processing unit, wherein
the tool includes a communications unit configured to transmit the captured image to the processor.
11. The tool system of claim 8 , wherein
the tool includes a notification unit configured to send a notification when the image processing unit identifies the actually shot work object.
12. The tool system of claim 8 , wherein
the image processing unit is configured to perform image processing in such a manner as to preferentially select, following a working procedure indicating an order of working process steps to be performed on the plurality of work objects, one reference image, corresponding to a work object to be processed in a forthcoming working process step, out of the plurality of reference images and compare the reference image selected with the captured image.
13. The tool system of any claim 8 , wherein
the tool is either a screwdriver or a wrench for use to perform work of attaching a plurality of fastening members onto the plurality of work objects, respectively, by turning the driving unit,
the tool system includes a target value storage unit configured to store a plurality of target values associated with the plurality of work objects, and
the tool further includes a driving control unit configured to control the driving unit by acquiring one target value, associated with the actually shot work object identified by the image processing unit, out of the plurality of target values such that a work value becomes a value based on the target value thus acquired.
14. The tool system of claim 13 , wherein
the tool includes a registration mode as an operation mode thereof,
the tool further includes a registration unit configured to perform image storage processing of making the image storage unit store the plurality of reference images when the operation mode of the tool is the registration mode and target value storage processing of making the target value storage unit store the plurality of target values,
the image storage processing includes making the image storage unit store, as the plurality of reference images, a plurality of still images generated by the image capturing unit by shooting the plurality of work objects, and
the target value storage processing includes making the target value storage unit store, as the plurality of target values, respective working settings defined when the plurality of fastening members are attached to the plurality of work objects.
15. The tool system of claim 13 , wherein
the tool further includes a decision unit configured to determine whether each of work values, generated when the plurality of fastening members are respectively attached to the plurality of work objects, is a normal one or not, and
the tool system includes a result storage unit configured to store respective decision results obtained by the decision unit for the plurality of work objects.
16. The tool system of any claim 13 , wherein
the image capturing unit is provided for the tool such that either a bit or socket attached to the tool falls within an image capturing range,
the image processing unit is configured to recognize, based on the captured image, a type of the bit or the socket, and
the driving control unit is configured to correct, according to the type of the bit or the socket recognized by the image processing unit, a target value associated with the actually shot work object and thereby control the driving unit such that the work value becomes equal to the target value thus corrected.
17. The tool system of claim 8 , wherein
the tool is either a screwdriver or a wrench for use to perform work of attaching a plurality of fastening members onto the plurality of work objects, respectively, by turning the driving unit,
the image capturing unit is provided for the tool such that either a bit or socket attached to the tool falls within an image capturing range,
