Lights up. Further, when the motor is set to the locked state by the second operation part, the illuminator is lit for the second time in response to the operation of the first operation part. That is, when an electric working machine that cannot drive a motor is used as the lighting device, the lighting time is changed from the lighting time when the electric working machine can work. Therefore, the illuminator of the electric working machine can be effectively used with a simple operation.

The electric operating machine may further include a grip portion configured to be gripped by a user's hand. The first operation unit may be provided at the first installation position of the electric working machine. The second operation section may be provided at the second installation position of the electric working machine. The first installation position and the second installation position may be within reach of the user holding the grip.

Since the first installation position and the second installation position are within reach of the hand of the user holding the grip, the user can operate the first operation unit and the second operation unit with the hand holding the grip. can be operated. As a result, the user can easily control the lighting of the illuminator with the hand holding the grip.

The second time period may be longer than the first time period.
By making the second time longer than the first time, the electric working machine can be used more effectively as a lighting device when the motor is locked by the second operation unit. can. Moreover, when the motor is set to the canceled state by the second operation unit, it is possible to suppress power consumption by the illuminator.

The lighting time of the illuminator is changed from the second time in response to the operation of the first operation unit again before the second time elapses. That is, when the electric working machine is used as the lighting device, the lighting time can be changed with a simple operation. As a result, the convenience of the illuminator of the electric working machine can be enhanced.

The lighting control unit may be configured to immediately turn off the illuminator in response to the first operation unit being operated again before the second time elapses.
The illuminator is immediately turned off in response to the first operation unit being operated again before the second time elapses. Therefore, when the electric working machine is used as a lighting device, the lighting device can be turned off when the user desires.

The lighting control unit turns on the illuminator in response to the unlocked state being detected by the state detecting unit before the second time elapses when the illuminator is turned on while the state detecting unit is detecting the locked state. may be configured to change the lighting time of from the second time.

If the release condition is detected before the second time elapses, the lighting time is changed from the second time. That is, when the use of the electric working machine as the lighting device is stopped while the electric working machine is being used as the lighting device, the lighting time of the illuminator can be changed.

When the lighting control unit turns on the illuminator while the state detection unit is detecting the unlocked state, the lighting control unit sets the lighting time to the first level even if the state detection unit detects the locked state before the first period of time elapses. may be configured to continue for the time of

If the locked state is detected before the first time elapses, the lighting time is maintained for the first time. That is, unless the first operating portion is operated while the motor is locked, the electric working machine cannot be used as a lighting device.

An operation detection unit configured to detect continuous operation of the first operation unit for a period longer than a predetermined time may be provided. The lighting control unit detects that the first operation unit is continuously operated by the operation detection unit before the second time elapses when the lighting device is turned on while the state detection unit is detecting the locked state. is detected, the lighting time of the illuminator may be changed from the second time.

The lighting time of the illuminator is changed from the second time in response to the continuous operation of the first operation unit before the second time elapses. There may be a case where the motor is locked and the electric working machine is housed in the case. At this time, something may come into contact with the first operating portion of the electric operating machine within the case, and the first operating portion may continue to be operated. In that case, the power consumption by the illuminator increases as the illuminator continues to illuminate for the second time. Therefore, the lighting time of the illuminator is changed in accordance with the continuous operation of the first operation unit before the second time elapses. Accordingly, it is possible to appropriately change the lighting time of the illuminator set according to the user's unintended operation of the first operation unit.

The illumination control unit is configured to immediately turn off the illuminator when the operation detection unit detects that the first operation unit is continuously operated before the second time elapses. may be

The illuminator is immediately extinguished in response to the continuous operation of the first operation unit before the second time elapses. As a result, it is possible to suppress the power consumption associated with the user's unintended operation of the first operation unit.

The electric operating machine may further include a third operation unit configured to be operated to enable or disable lighting of the illuminator. The illumination control section may be configured to enable or disable lighting of the illuminator according to the operation of the third operation section. Further, the illumination control unit responds to the operation of the first operation unit while the state detection unit is detecting the canceled state when the lighting of the illuminator is disabled by the third operation unit. , may be configured to keep the illuminator off. Further, the illumination control unit responds to the operation of the first operation unit while the state detection unit is detecting the locked state when the lighting of the illuminator is disabled by the third operation unit. , may be configured to illuminate the illuminator.

Even when the lighting of the illuminator is disabled, the illuminator can be turned on when the electric working machine is used as the lighting device.

The lighting control unit prohibits changing the setting of enabling or disabling lighting of the illuminator according to the operation of the third operation unit when the illuminator is turned on while the state detection unit detects the locked state. may be configured to

When the electric working machine is used as the lighting device, the setting of enabling or disabling lighting of the illuminator cannot be changed. As a result, when the motor is returned from the locked state to the released state, it is possible to take over the setting of enabling or disabling lighting of the illuminator in the previous released state.

The electric working machine may further include a notification unit configured to notify that the illuminator is on while the state detection unit detects the locked state.
It is reported that the illuminator is on during detection of the lock condition. Thereby, the user can recognize that the lighting time of the illuminator is different from that when the electric working machine is available for work.

The motor may be configured to operate in multiple modes of operation. The notification unit may further be configured to notify the current operating mode of the motor.

The forward/reverse selector switch 10A is configured to be operated by a user in order to switch the rotation direction of the motor 50 between the forward direction and the reverse direction opposite to the forward direction. When the motor 50 rotates in the forward direction, the tool bit rotates in the screw tightening direction, and when the motor 50 rotates in the reverse direction, the tool bit rotates in the screw loosening direction.

Further, the normal/reverse selector switch 10A is configured to be operated by a user to lock the motor 50 in a non-driving state regardless of whether or not a trigger 7A, which will be described later, is operated. Hereinafter, a state in which the motor 50 is locked in the non-driving state is referred to as a locked state, and a state in which the motor 50 is not locked in the non-driving state is referred to as a released state.

Specifically, the normal/reverse selector switch 10A is configured to be slidable between a first operating position and a second operating position. In FIG. 1, the first operating position is the rightmost position, and the second operating position is the leftmost position.

Rotate in the opposite direction. Further, when the normal/reverse selector switch 10A is positioned at the neutral position, the motor 50 is locked. The neutral position corresponds to an intermediate position between the first operating position and the second operating position. When the motor 50 is locked, the impact driver 1A cannot be used for work. In the present embodiment, the normal/reverse selector switch 10A corresponds to an example of the second operation section of the present disclosure.

The trigger 7A is provided below the mode switch 9 on the front side of the handgrip 5A. The trigger 7A is arranged at a position where it can be operated by the hand holding the handgrip 5A. Therefore, the user can operate the mode changeover switch 9, the normal/reverse changeover switch 10A and the trigger 7A with the hand holding the handgrip 5A. That is, the user can hold and operate the impact driver 1A with one hand.

Trigger 7A is configured to be operated by a user to drive motor 50. As shown in FIG. Also, the trigger 7A is configured to be operated by the user to turn on the light 20A. Specifically, when the forward/reverse selector switch 10A is positioned at the first operating position or the second operating position, that is, when the motor 50 is in the released state, the trigger 7A is pulled by the first pull amount. In response to this, the light 20A lights up. Further, when the motor 50 is in the released state, the motor 50 is driven in response to the trigger 7A being pulled by the second pulling amount. The second pull amount is greater than the first pull amount. When the trigger 7A is pulled by the second pull amount or more while the motor 50 is released, a command value for the rotation speed of the motor 50 is set according to the pull amount. As the pulling amount increases, the rotational speed command value is set larger.

Specifically, the microcomputer 100 has various functions such as a power switch determination unit 110, a speed command determination unit 120, a normal/reverse determination unit 130, a lock determination unit 140, a mode determination unit 150, a pulse width A modulation generation unit (PWM generation unit) 160 , a drive control unit 170 , a rotation speed calculation unit 180 , a light control unit 190 and a display control unit 200 are provided.

The power switch determination unit 110 determines whether the power is turned on or off depending on whether the input signal from the power switch 71 is an on signal or an off signal. Then, the power switch determination unit 110 outputs the power-on or power-off determination result to the PWM generation unit 160 .

The speed command determination unit 120 determines the speed command value commanded by the user according to the resistance value input from the speed setting unit 72 . Specifically, the speed command determination unit 120 determines the speed command value to be 0 when the resistance value is less than the resistance threshold value. The resistance threshold corresponds to a resistance value corresponding to the first pull amount. Further, when the resistance value is equal to or greater than the resistance threshold value, the speed command determination unit 120 determines a speed command value that increases as the resistance value increases.

That is, the display control section 200 controls the notification of the operation mode notification section 14 according to the operation mode determined by the mode determination section 150 . When the light mode is on, the display control unit 200 causes the light mode notification unit 15 to notify that the light 20A is on while the motor 50 is locked.

10 and 11 show time charts according to the reference example. In FIG. 10, the motor 50 is in the released state from time t110 to time t116, and the motor 50 is in the locked state from time t116 to time t121. Also, the lighting of the light 20A is set to be valid (that is, the light function is ON) from time t110 to time t121. When the power switch 71 is turned on at times t110, t113 and t117, the light 20A is turned on. Then, when the power switch 71 is turned off at times t111, t114, and t118, the light 20A is continuously lit for a certain lighting time T0 from times t111, t114, and t118. Then, the light 20A is turned off at times t112, t115 and t119. In the present embodiment, the time from when the power switch 71 is turned off after the light 20A is turned on to when the light 20A is turned off is referred to as the lighting time. The time from when the light 20A is turned on to when the light 20A is turned off may be referred to as the lighting time.

In FIG. 11, the motor 50 is in the unlocked state from time t130 to time t136, and the motor 50 is in the locked state after time t136. At time t130, lighting of the light 20A is enabled. At time t130, when the power switch 71 is turned on, the light 20A is turned on. Then, when the power switch 71 is turned off at time t131, the striking/light switch 12 is pressed at time t132 before a certain lighting time T0 elapses from time t131, and the striking/light switch 12 is turned off at time t133. It is determined that the button has been pressed for a long time. Accordingly, at time t133, the lighting of the light 20A is disabled (that is, the light function is turned off), and the light 20A is turned off before the lighting time T0 elapses.

Further, at time t139, the power switch 71 is turned on. Since lighting of the light 20A is disabled at this time, the light 20A does not light. After the power switch 71 is turned off at time t140, the hit/light switch 12 is pressed at time t141, and it is determined at time t142 that the hit/light switch 12 is long pressed. Accordingly, lighting of the light 20A is enabled at time t142. Since the time from time t140 to time t142 is shorter than the lighting time T0, the light 20A is turned on at time t142 and turned off at time t143. The period from time t140 to time t143 corresponds to lighting time T0.

Therefore, in the reference example, regardless of whether the motor 50 is in the released state or the locked state, the light 20A is turned on for a certain period of time when the trigger 7A is pulled. That is, in the reference example, the lighting time of the light 20A when the electric working machine is used as the lighting device is the same as the lighting time of the light 20A when working with the electric working machine.

Furthermore, in the reference example, regardless of whether the motor 50 is in the unlocked state or locked state, the light 20A does not light when the lighting of the light 20A is disabled. That is, in the reference example, when the electric operating machine is used as the lighting device, the light 20A cannot be turned on unless the lighting of the light 20A is set to be valid.

In contrast, in the present embodiment, the light control unit 190 changes the lighting time of the light 20A when the motor 50 is in the locked state from the lighting time of the light 20A when the motor 50 is in the unlocked state.

Further, in the present embodiment, the light control unit 190 controls when the trigger 7A is pulled when the motor 50 is locked regardless of whether the lighting of the light 20A is enabled or disabled. , to turn on the light 20A. First to fifth examples according to the present embodiment will be described below with reference to FIGS. 5 to 9. FIG.

FIG. 5 shows a first example according to this embodiment. In FIG. 5, the motor 50 is in the unlocked state from time t10 to time t16, and the motor 50 is in the locked state after time t16. When the power switch 71 is turned on at time t10 in the disengaged state of the motor 50, the light 20A is turned on. Then, when the power switch 71 is turned off at time t11, the light 20A is continuously lit for the first lighting time T1 from time t11. Then, at time t12, the light 20A is turned off. The light 20A is lit at the first luminance from time t10 to time t12.

When the power switch 71 is turned on at time t17 in the locked state of the motor 50, the light 20A is turned on. Then, when the power switch 71 is turned off at time t18, the light 20A is continuously lit for the second lighting time T2 from time t18. Then, at time t19, the light 20A is turned off. From time t17 to time t19, the light 20A is lit with the second luminance.

The second lighting time T2 is different from the first lighting time T1. In this embodiment, the second lighting time T2 is longer than the first lighting time T1. As a result, when the impact driver 1A is not used for work and the impact driver 1A is used as a lighting device, the lighting time of the light 20A can be lengthened. The first lighting time T1 and the second lighting time T2 are preset and stored in the ROM 100b. Note that in the present disclosure, the second lighting time T2 does not necessarily have to be set longer than the first lighting time T1, and the second lighting time T2 may be set shorter than the first lighting time T1. good.

Also, the second luminance is different from the first luminance. Specifically, when lighting the light 20A at the first luminance, the light control unit 190 outputs a first PWM signal having a first duty ratio to the light 20A. Further, when lighting the light 20A at the second luminance, the light control unit 190 outputs a second PWM signal having a second duty ratio different from the first duty ratio to the light 20A. In this embodiment, the second luminance is higher than the first luminance. That is, the light control section 190 makes the second duty ratio larger than the first duty ratio. Thereby, when the impact driver 1A is used as an illumination device, the brightness of the light 20A can be increased. The first luminance and the second luminance are preset and stored in the ROM 100b. Note that, in the present disclosure, the second luminance does not necessarily have to be different from the first luminance, and the second luminance may be the same as the first luminance.

Next, FIG. 6 shows a second example according to this embodiment. In FIG. 6, the motor 50 is in the released state from time t30 to time t36, and the motor 50 is in the locked state after time t36. Time t30 to time t36 are the same as time t10 to time t16 shown in FIG. When the power switch 71 is turned on at time t37 in the locked state of the motor 50, the light 20A is turned on. When the power switch 71 is turned off at time t38, the power switch 71 is turned on and the light 20A is turned off at time t39 before the second lighting time T2 elapses from time t38. That is, when the user is using the impact driver 1A as a lighting device, the user can immediately turn off the light 20A by pulling the trigger 7A again before the second lighting time T2 elapses.

When the trigger 7A is pulled again before the second lighting time T2 elapses, the lighting time is changed from the lighting time when the trigger 7A is not pulled again without immediately extinguishing the light 20A. may Specifically, after the power switch 71 is turned on at time t39, when the power switch 71 is turned off at time t40, the light 20A is continuously turned on from time t40 until the third lighting time T3 elapses. You may

Note that the third lighting time T3 may be any value. When the third lighting time T3 is set to 0 seconds, the light 20A is immediately extinguished when the power switch 71 is turned on at time t39. The third lighting time T3 is preset and stored in the ROM 100b.

Next, FIG. 7 shows a third example according to this embodiment. In FIG. 7, the motor 50 is in the released state from time t50 to time t55, and the motor 50 is in the locked state from time t55 to time t59. After time t59, the motor 50 is in the released state.

When the power switch 71 is turned on at time t53 in the disengaged state of the motor 50, the light 20A is turned on, and the power switch 71 is turned off at time t54. At time t55 before the first lighting time T1 elapses from time t54, the reverse rotation switch 102 is turned off and the motor 50 is locked. However, the light mode is not turned on and the lighting time is not changed. The light mode is turned on in response to turning on the power switch 71 while the motor 50 is locked. Even if the motor 50 is locked when the motor 50 is lit while the motor 50 is released, the light mode is not turned on, and the lighting time in the released state is maintained. The lighting of the light 20A continues until time t56, and the light 20A is turned off at time t56. The time from time t54 to time t56 corresponds to the first lighting time T1.

When the power switch 71 is turned on at time t57 while the motor 50 is locked, the light 20A is turned on, and the power switch 71 is turned off at time t58. At time t59, before the second lighting time T2 elapses from time t58, the forward rotation switch 101 is turned on and the lock of the motor 50 is released. Accordingly, at time t59, the light mode is changed from ON to OFF, and the lighting time of the light 20A is changed.

Specifically, the light 20A is turned on during the fourth lighting time T4 from time t59, and is turned off at time t60. The fourth lighting time T4 may be any value, and may be the same value as the first lighting time T1. The fourth lighting time T4 is preset and stored in the ROM 100b.

Next, FIG. 8 shows a fourth example according to this embodiment. In FIG. 8, the motor 50 is in the released state from time t70 to time t76, and the motor 50 is in the locked state after time t76. When the power switch 71 is turned on at time t77 in the locked state of the motor 50, the light 20A is turned on. At time t78, it is determined that the power switch 71 has been pressed for a long time, and the light 20A is turned off. That is, when the user is using the impact driver 1A as a lighting device, the user continues to pull the trigger 7A for longer than a predetermined time, thereby turning on the light 20A in response to the long-pressing of the power switch 71. It can be extinguished immediately.

It should be noted that the lighting time of the light 20A may be changed instead of turning off the light 20A immediately after it is determined that the power switch 71 has been pressed for a long time while the motor 50 is locked. Specifically, at time t79, the light 20A may be lit during the fifth lighting time T5 from time t79 in response to the power switch 71 being turned off.

Note that the fifth lighting time T5 may be any value. When the fifth lighting time T5 is set to zero, the light 20A is immediately turned off when it is determined that the power switch 71 has been pressed for a long time at time t78. The fifth lighting time T3 is preset and stored in the ROM 100b.

Next, FIG. 9 shows a fifth example according to this embodiment. In FIG. 9, the motor 50 is in the released state from time t90 to time t96, and the motor 50 is in the locked state from time t96 to time t102. After time t102, the motor 50 is in the released state.

When the power switch 71 is turned on at time t90 in the disengaged state of the motor 50, the light 20A is turned on, and the power switch 71 is turned off at time t91. Before the first lighting time T1 elapses from time t91, the impact/light switch 12 is pressed at time t92, and the long press of the impact/light switch 12 is determined at time t93. Accordingly, lighting of the light 20A is switched from enabled to disabled, and the light 20A is turned off at time t93.

When the power switch 71 is turned on at time t97 in a state where the motor 50 is locked and lighting of the light 20A is disabled, the light 20A is turned on. When the power switch 71 is turned off at time t98, the light 20A is turned on until the second lighting time T2 elapses from time t98, and the light 20A is turned off at time t101. That is, when the motor 50 is locked, the light 20A is lit even if the lighting of the light 20A is disabled.

Between time t98 and time t101, at time t99, the hitting/light switch 12 is pressed, and at time t100, it is determined that the hitting/light switch 12 is long pressed.However, between time t99 and time t101, Since the light mode is on, the lighting of the light 20A is not switched from disabled to enabled and is maintained disabled. That is, while the light mode is on, lighting of the light 20A cannot be switched from disabled to enabled or from enabled to disabled.

At time t102, the forward rotation switch 101 is turned on and the motor 50 is unlocked. In the state where the motor 50 is released and the lighting of the light 20A is disabled, the power switch 71 is turned on at time t103, but the light 20A does not light.

In S110, based on the determination results of S70, S90 and S100, it is determined whether or not the forward/reverse selector switch 10A is in the neutral position. If it is determined in S110 that the forward/reverse selector switch 10A is in the forward rotation position or the reverse rotation position, the process proceeds to S120. In S120, it is determined that the motor 50 is in the released state, and the process proceeds to S140.

On the other hand, if it is determined in S110 that the normal/reverse selector switch 10A is in the neutral position, the process proceeds to S130. At S130, it is determined that the motor 50 is locked, and the process proceeds to S140.

In S140, it is determined whether or not the trigger 7A has been operated, that is, whether or not the power switch 71 is outputting an ON signal. If it is determined in S140 that the trigger 7A has not been operated, the process proceeds to S150. In S150, it is determined that the power switch 71 is off, and the process proceeds to S300.

On the other hand, if it is determined in S140 that the trigger 7A has been operated, the process proceeds to S160. In S160, it is determined that the power switch 71 is on, and the process proceeds to S170.

In S170, it is determined whether or not a long press of the power switch 71 has been detected. That is, it is determined whether or not it has been detected that the trigger 7A has been pulled by the first pull amount or more for a period longer than a predetermined time. If it is determined in S170 that a long press of the power switch 71 has been detected, the process proceeds to S180, and if it is determined that a long press of the power switch 71 has not been detected, the process proceeds to S190.

In S180, it is determined that the power switch 71 has been pressed long, and the process proceeds to S190.
In S190, it is determined whether the trigger 7A has changed from off to on. That is, it is determined whether or not the power switch 71 has changed from off to on. If it is determined in S190 that the trigger 7A has not changed from OFF to ON, the process proceeds directly to S300. If it is determined in S190 that the trigger 7A has changed from OFF to ON, the process proceeds to S200.

In S200, it is determined that the power switch 71 has been switched from OFF to ON, and the process proceeds to S300.
In S300, a light process for controlling lighting of the light 20A is executed. Details of the write processing will be described later.

<2-2. Write processing>
Next, write processing executed by the microcomputer 100 according to this embodiment will be described with reference to FIGS. 13A to 13D.

First, in S310, it is determined whether or not the light 20A is on. If it is determined that the light 20A is on, the process proceeds to S320, and if it is determined that the light 20A is off, the process proceeds to S610.

In S320, it is determined whether or not the power switch 71 is on based on the determination results in S150 and S160. If the power switch 71 is off, the process proceeds to S330, and if the power switch 71 is on, the process proceeds to S340.

At S330, the count is added. This count is a count for measuring the lighting time, and addition of the count starts when the power switch 71 is switched from on to off. After that, the process proceeds to S380.

In S340, it is determined whether the power switch 71 has been pressed long based on the presence or absence of the determination result in S180. If the power switch 71 has not been pressed long, the process proceeds to S360, and if the power switch 71 has been pressed long, the process proceeds to S350.

In S350, it is determined whether or not the motor 50 is locked based on the determination results of S120 and S130. If the motor 50 is in the unlocked state, the process proceeds to S360, and if the motor 50 is in the locked state, the process proceeds to S370.

At S360, the count is cleared. That is, the count is not added until the duration of the ON state of the power switch 71 exceeds the predetermined time for judging the long push, or when the long push is judged while the motor 50 is in the released state. After that, the process proceeds to S380.
At S370, the count is added. That is, the time is measured from the point in time when the power switch 71 is kept on for a predetermined period of time. The addition of the count here corresponds to measuring the fifth lighting time in the fourth example shown in FIG.

Subsequently, in S380, it is determined whether or not the write mode is on. That is, it is determined whether or not the light 20A is lit in the light mode. If it is determined in S380 that the light mode is off, the process proceeds to S390.

In S390, it is determined whether or not the power switch 71 has been switched from OFF to ON based on the presence or absence of the determination result in S200. That is, it is determined whether or not the power switch 71 has been switched from off to on when the light mode is off.

Subsequently, in S690, the count is cleared, this process is temporarily terminated, and the process is restarted from the process of S10.

<3. Effect>
According to this embodiment described above, the following effects are obtained.
(1) A first lighting time T1 is set as the lighting time in response to the trigger 7A being pulled when the motor 50 is in the released state. Further, the second lighting time T2 is set as the lighting time in response to the trigger 7A being pulled when the motor 50 is in the locked state. Therefore, the lighting time when the impact driver 1A is used as a lighting device can be changed from the lighting time when the electric working machine can work. Therefore, the light 20A can be effectively used with a simple operation.

(2) The installation position of the trigger 7A and the installation position of the normal/reverse selector switch 10A are within reach of the user holding the handgrip 5A. Therefore, the user can operate the trigger 7A and the normal/reverse selector switch 10A with the hand holding the handgrip 5A. As a result, the user can easily control lighting of the light 20A with the hand holding the handgrip 5A.

(3) By setting the second lighting time T2 longer than the first lighting time T1, the impact driver 1A can be used more effectively as a lighting device when the motor 50 is locked. . Further, when the motor 50 is in the released state, the power consumption of the battery pack 3 by the light 20A can be suppressed.

(4) The lighting time is changed in response to the trigger 7A being pulled again before the second lighting time T2 elapses. That is, when the impact driver 1A is used as a lighting device, the lighting time can be changed with a simple operation. As a result, the convenience of the illuminator of the impact driver 1A can be enhanced.

(5) The light 20A is immediately extinguished in response to the trigger 7A being pulled again before the second lighting time T2 elapses. Therefore, when the impact driver 1A is used as a lighting device, the light 20A can be turned off when the user desires.

(6) If the released state of the motor 50 is detected before the second lighting time T2 elapses, the lighting time is changed. That is, when the use of the impact driver 1A as the lighting device is stopped while the impact driver 1A is being used as the lighting device, the lighting time of the light 20A can be changed.

(7) If the locked state of the motor 50 is detected before the first lighting time elapses, the lighting time is not changed. That is, unless the trigger 7A is pulled while the motor 50 is locked, the impact driver 1A cannot be used as a lighting device.

(8) The lighting time is changed in response to the continuous pulling of the trigger 7A before the second lighting time elapses. There may be cases where the motor 50 is locked and the impact driver 1A is housed in the case. At this time, something may come into contact with the trigger 7A of the impact driver 1A within the case, and the trigger 7A may continue to be pulled. In that case, if the light 20A continues to light until the second lighting time T2 elapses, the power consumption of the battery pack 3 by the light 20A increases. Therefore, by changing the lighting time in response to the continuous pulling of the trigger 7A before the second lighting time T2 elapses, the lighting time set in response to the user's unintended operation of the trigger 7A can be changed. can be changed appropriately.

(9) The light 20A is immediately extinguished in response to the continuous pull of the trigger 7A before the second lighting time T2 elapses. As a result, power consumption of the battery pack 3 associated with the user's unintended operation of the trigger 7A can be suppressed.

(10) Even if lighting of the light 20A is disabled, the light 20A can be turned on when the impact driver 1A is used as a lighting device.
(11) When the impact driver 1A is used as a lighting device, the setting of enabling or disabling lighting of the light 20A cannot be changed. As a result, when the motor 50 is returned from the locked state to the released state, it is possible to take over the setting of enabling or disabling lighting of the light 20A in the previous released state.

(12) It is notified that the light 20A is on while the locked state of the motor 50 is being detected. Thereby, the user can recognize that the lighting time of the light 20A is different from that when the impact driver 1A can work.

(13) Since the same notification unit notifies the operation mode and the lighting of the light 20A, it is possible to reduce the number of components and thus the installation space for the notification unit.
(14) The brightness when using the impact driver 1A as a lighting device is different from the brightness when the impact driver 1A can work. Therefore, the light 20A can be used more efficiently.

(15) The rotation direction of the motor 50 can be switched by switching the normal/reverse selector switch 10A between the first operating position and the second operating position. Furthermore, the motor 50 can be locked by setting the normal/reverse selector switch 10A to the neutral position. That is, the motor 50 can be locked using a switch for switching the rotation direction of the motor 50 without increasing the number of parts.

(16) When the motor 50 is in the released state, the light 20A can be turned on or the motor 50 can be driven according to the amount of pulling the trigger 7A.
(17) When the normal/reverse selector switch 10A is in the neutral position, the light 20A can be turned on by pulling the trigger 7A by the first pull amount.
