Abstract: An electric working machine of an example of the present disclosure includes: a motor; a power supply portion; a controller; and a voltage detector. The power supply portion generates a DC voltage to drive the motor by rectifying an AC voltage supplied from an AC power source and smoothing by a capacitor. The controller controls energization of the motor. The voltage detector detects the AC voltage. The controller is configured to interrupt the energization when the voltage detector does not detect the AC voltage.

Abstract: A portable inflator (1) includes a motor (51), a compression mechanism (6) driven by the motor (51) to compress and discharge air, a main body housing (2), a leg (3), a grip (4), and a manually-operable trigger (41) provided on the grip. The main body housing (2) includes a battery mount part (251) for detachably mounting a battery (8), and houses the motor (51) and the compression mechanism (6). The leg (3) supports the main body housing (2) when a lower surface (31) of the leg (3) is disposed on a placement surface (P). The grip (4) is connected to the main body housing (2) and extends at least substantially parallel to the lower surface (31) of the leg (3). The motor (51) is driven in accordance with pulling of the trigger (41).

Abstract: A power tool includes a tool-main-body part, an electric motor as a drive source, a grip part, which extends downward from the tool-main-body part and is configured to be gripped by a user, and a power-supply unit at a tip of the grip part. The power tool includes a controller configured to control the operation of the electric motor, the controller being located on the power-supply unit, and a display controlled by the controller and configured to indicate an operating state of the electric motor. The controller and the display each have a flat-plate shape and are disposed along a surface direction with respect to one another, and the display includes a first portion that overlies the controller and a second portion that projects beyond an end edge of the controller.

Abstract: One aspect of the present disclosure is an inspection apparatus of a battery pack for an on-site electric apparatus, which comprises a coupler, a discharger, a changer, a discharge performing device, a voltage value detector, and a calculator. The changer detects one of a nominal voltage value of the battery pack coupled to the coupler and a voltage value of a battery in the battery pack, and reduces a discharge time of the battery and/or a discharge current value of the battery as the detected value is larger.

Abstract: A dust collector in one aspect of the present invention comprises a dust collection portion, a communication portion, and an interlock operation control portion. When the communication portion receives an interlock command transmitted from an electric working machine, the interlock operation control portion makes the dust collection portion operate interlocking with the electric working machine. The interlock operation control portion includes a storage portion, in which identification information specific to the electric working machine with which the dust collection portion is to be made to perform the interlock operation is stored.

Abstract: A dust collector for electric power tool includes a casing, a ring-shaped suction opening, a dust collecting route, and a filter. The suction opening protrudes forward from the casing. The tool bit of the electric power tool is insertable into the suction opening in a state where the suction opening is brought into contact with a surface to be processed. The dust collecting route is formed within the casing and guides an air suctioned from the suction opening to a dust collection portion in the casing. The filter is disposed in the dust collection portion to capture dust suctioned with the air. On the dust collecting route in the dust collection portion, a first filter and a second filter are disposed. The first filter includes a dust collecting chamber partitioned inside the dust collection portion. The second filter is arranged outside the first filter independently from the first filter.
