  The tool side identification memory 26 is a memory capable of storing an identification code, and an identification code is set in advance. In the power feeding side identification memory 17 on the power feeding device 1 side, the same identification code as that stored in the tool side identification memory 26 by the ten key 18 is stored.

  The authentication memory 27 is a memory capable of storing authentication information.

Next, the operation of the non-contact charging power tool system configured as described above will be described.
First, when the power tool 2 is placed on the power supply device 1 and the object discrimination circuit 15 determines that the power tool 2 is appropriately close to the power tool 2, the primary side communication circuit 16 and the secondary side communication / control circuit 25. And information communication is performed. Then, the identification / authentication determination unit 30 determines whether or not the identification code stored in the power supply side identification memory 17 matches the identification code stored in the tool side identification memory 26. Also, in the identification / authentication determination unit 30, whether or not the authentication information (numerical authentication information and fingerprint authentication information) input by the numeric keypad 28 and the fingerprint authentication sensor 29 matches the authentication information stored in the authentication memory 27.

The power supply circuit 12 generates a high-frequency current for power supply.

  Then, an alternating magnetic field is generated in the power transmission coil 14 supplied with the high-frequency current, and an induction current is generated by electromagnetic induction in the power receiving coil 21 in the environment. Then, the induced current is rectified in the power receiving circuit 22 to generate a DC voltage, and the DC voltage is supplied to the secondary battery 23 to charge the secondary battery 23.

  Here, for example, if the identification / authentication determination unit 30 determines that at least one of the identification code and the authentication information does not match, the power supply instruction signal is not output, and the secondary battery 23 is charged. Not done.

Next, the characteristic effects of the above embodiment will be described below.
(1) The identification code stored in the power supply side identification memory 17 and the identification code stored in the tool side identification memory 26 match, and the input authentication information matches the authentication information stored in the authentication memory 27. Power supply is permitted only in cases. In other words, charging is not possible when at least one of the identification code and the authentication information does not match. Therefore, for example, even if one of the power supply device 1 and the power tool 2 or the whole non-contact charging power tool system is stolen, it can be reminiscent of being unable to charge and immediately usable, and high theft deterrence. An effect can be obtained.

  (2) Since the authentication information stored in the authentication memory 27 can be arbitrarily set, convenience and theft deterrent effect can be enhanced. Specifically, in the present embodiment, since the numeric keypad 28 is included as the authentication input means, it is possible to set numerical authentication information that only the user can know and can be easily remembered by the user. Moreover, in this embodiment, since the fingerprint authentication sensor 29 which is a biometric authentication sensor is included as an authentication input means, it becomes difficult to authenticate other than a user, and the antitheft effect can be enhanced.

  (3) Since the electric tool 2 is provided with the authentication input means for inputting the authentication information, that is, the numeric keypad 28 and the fingerprint authentication sensor 29, the antitheft effect of the electric tool 2 can be mainly enhanced.

  (4) In addition to the numeric keypad 28 and the fingerprint authentication sensor 29, the authentication memory 27 and the identification / authentication determination unit 30 as an authentication determination unit are provided in the electric power tool 2. For example, an identification code is stored in a different power supply device 1. Thus, even different power supply devices 1 can be charged. Further, for example, an operation other than charging (for example, operation of the electric tool 2 by an operation switch) is made valid only when the input authentication information matches the authentication information stored in the authentication memory 27. Can do. Therefore, the antitheft effect of the electric power tool 2 can be enhanced.

  (5) Since the power feeding device 1 includes the identification input means (tenkey 18) capable of arbitrarily setting the identification code stored in the power feeding side identification memory 17, for example, the electric power tool 2 that can charge the single power feeding device 1 Can be added. In this embodiment, since the numeric keypad 18 is included as the identification input means, the identification code can be easily input.

The above embodiment may be modified as follows.
-You may add the function for preventing or suppressing theft to the electric tool 2 of the said embodiment further.

  For example, as shown in FIG. 2, the electric tool 2 further includes a security mode setting unit 41, a vibration sensor 42 as an external sensor, an abnormality determination unit 43, and a warning sound generation unit 44 as an abnormal state notification unit. It is good. The security mode setting unit 41 switches between the normal mode and the security mode. In this example, after using the electric tool 2 (after the operation switch is turned off), a preset time (for example, 10 minutes) ), The normal mode is switched to the security mode. The security mode setting unit 41 in this example switches the security mode to the normal mode when the input authentication information matches the authentication information stored in the authentication memory 27, and validates the operation of the operation switch. The vibration sensor 42 is for detecting an abnormal vibration that is one of the external states in the security mode, and outputs the detected information to the abnormality determination unit 43. The abnormality determination unit 43 determines whether or not there is an abnormality based on the external state detected by the vibration sensor 42 in the security mode. The warning sound generation unit 44 generates a warning sound and notifies the abnormal state to the outside when the abnormality determination unit 43 determines that there is an abnormality.

  In the above configuration, the security mode setting unit 41 sets the security mode, and if the abnormality determination unit 43 determines that there is an abnormality based on the external state detected by the vibration sensor 42, the warning sound generation unit 44 A warning sound is generated to notify the abnormal state. If it does in this way, the vibration etc. which generate | occur | produced in the vehicle which should be in an unmanned state, for example can be detected with the vibration sensor 42, and the abnormal state can be alert | reported to the circumference | surroundings. Therefore, the antitheft effect can be obtained. In addition, since the security mode setting unit 41 switches to the security mode when a preset time has elapsed after using the electric power tool 2, the anti-theft effect can be obtained even if the user does not perform a specific operation. Can do.

  Further, for example, as shown in FIG. 3, the power tool 2 may further include a wireless circuit unit 45 and a communication antenna 46 constituting an external communication unit as an abnormal state notification unit. In this example, when the abnormality determination unit 43 determines that there is an abnormality, a warning sound is generated by the warning sound generation unit 44 and an abnormal state is notified to the surroundings, and the wireless circuit unit 45 and the communication antenna 46 are also detected. Thus, an abnormal state is notified to an external information communication terminal such as a mobile phone. In this way, the user can easily recognize the abnormal state even if he / she is away, for example, with an external information communication terminal such as a mobile phone.

  As shown in FIG. 3, the electric power tool 2 further includes a GPS receiving circuit 47 and a GPS antenna 48 that constitute GPS receiving means capable of receiving GPS (position) information, and the radio circuit unit 45 and the communication antenna 46 are provided. The information to be notified may include the GPS information. In this way, the user can easily recognize the GPS information, that is, the position of the electric power tool 2, even if the user is away, for example, with an external information communication terminal such as a mobile phone.

  In the other example (see FIGS. 2 and 3), the vibration sensor 42 is provided as an external sensor for detecting an external state. However, if an abnormal change in the external state can be detected, for example, a sound sensor (microphone) may be used. It may be changed.

Moreover, it is good also as a structure provided with the light emission part etc. which emit light as an abnormal condition alerting | reporting part.
In addition, the security mode setting unit 41 switches from the normal mode to the security mode when a preset time has elapsed after using the electric power tool 2, but the present invention is not limited to this. It is good also as a structure which switches.

  In the above embodiment, the electric power tool 2 includes the authentication input means (the numeric keypad 28 and the fingerprint authentication sensor 29), the authentication memory 27, the identification / determination determination unit 30 that constitutes the identification determination unit and the authentication determination unit. It is good also as a structure provided in the electric power feeder 1 with at least 1 of these.

  For example, as shown in FIG. 4, a power supply apparatus including a fingerprint authentication sensor 51 as an authentication input unit, an authentication memory 52, an identification / authentication determination unit 53 constituting an identification determination unit and an authentication determination unit, and a charge control circuit 54 It may be changed to 1. In this example, first, the electric power tool 2 is placed on the power feeding device 1, and when the object determination circuit 15 determines that the electric power tool 2 is appropriately close, the primary side communication circuit 16 and the secondary side communication are connected. Information communication is performed via the control circuit 25. Then, the identification / authentication determination unit 53 determines whether or not the identification code stored in the power supply side identification memory 17 matches the identification code stored in the tool side identification memory 26. Further, the identification / authentication determination unit 53 determines whether the authentication information (fingerprint authentication information) input by the fingerprint authentication sensor 51 matches the authentication information stored in the authentication memory 52. When it is determined that the identification code and the authentication information match, the charging control circuit 54 outputs a power supply instruction signal to the control circuit 13, and the power supply circuit 12 generates a high-frequency current for power supply.

  As described above, when the power supply device 1 includes the fingerprint authentication sensor 51, the authentication memory 52, and the identification / authentication determination unit 53 (authentication determination unit), it is possible to mainly obtain the antitheft effect of the power supply device 1.

In this example, the fingerprint authentication information of the user is read by the fingerprint authentication sensor 61 on the electric power tool 2 side, but coincides with the fingerprint authentication information stored in the authentication memory 62 by the identification / authentication determination unit 63 on the power supply device 1 side. It is determined whether or not. If it does in this way, in order to charge with different electric power feeder 1, it is necessary to memorize | store authentication information in this electric power feeder 1 previously, and charging with the different electric power feeder 1 becomes more difficult. Therefore, the theft deterrent effect when only one of the power feeding device 1 and the electric tool 2 is stolen can be enhanced.

  Further, for example, as shown in FIG. 6, an identification memory / authentication determination unit 73 constituting an authentication memory 72, an identification determination unit, and an authentication determination unit, while the power supply device 1 includes a fingerprint authentication sensor 71 as an authentication input unit, In addition, the power tool 2 including the charge control circuit 74 may be changed. In this example, the fingerprint authentication information of the user is read by the fingerprint authentication sensor 71 on the power supply apparatus 1 side, but coincides with the fingerprint authentication information stored in the authentication memory 72 by the identification / authentication determination unit 73 on the power tool 2 side. It is determined whether or not. If it does in this way, in order to charge different electric tools 2, it is necessary to memorize | store authentication information beforehand in this electric tool 2, and charge of different electric tools 2 becomes more difficult. Therefore, the theft deterrent effect when only one of the power feeding device 1 and the electric tool 2 is stolen can be enhanced.

  Moreover, in the said embodiment and another example, although identification / authentication determination part 30,53,63,73 was provided in the electric power feeder 1 or the electric tool 2, the identification determination part which performs determination of an identification code, and determination of authentication information are performed. The authentication determination unit to be performed may be provided separately for the power feeding device 1 and the power tool 2. In addition, an identification determination unit for determining the identification code may be provided in both the power supply device 1 and the electric tool 2, or an authentication determination unit for determining authentication information is provided in both the power supply device 1 and the electric tool 2.

  In the above embodiment and other examples, the authentication input means is the numeric keypad 28 or the fingerprint authentication sensors 29, 51, 61, 71. However, other keys may be used to input alphabets, and voiceprint authentication is performed by the authentication determination unit. A microphone or the like as a biometric sensor may be provided to determine information. Further, the authentication input unit may not be provided in the power feeding device 1 and the electric tool 2 and the authentication information may be input by an external information communication terminal such as a mobile phone by external communication.
