Abstract: A motor driven appliance in one aspect of embodiments of the present disclosure comprises a light source, a lighting unit, a motor, an operation unit, an operation detector, a reference signal output unit, a determination unit, and a control unit. The operation detector detects that the operation unit is operated, and outputs an operation detection signal that indicates that the operation unit is operated. The reference signal output unit outputs at least one reference signal that can be used as a reference for determining whether the detection by the operation detector is normal. The determination unit determines whether the operation unit is actually operated based on the operation detection signal and the at least one reference signal. The control unit controls operation of the lighting unit based on the determination made by the determination unit.

Abstract: A grinder includes a motor, a housing that houses the motor, a spindle that projects from the housing and is driven by the motor, and thereby rotates relative to the housing, and a wheel cover that is disposed on an outer-circumference side of the spindle and is configured to cover a portion of a tool accessory attached to the spindle. The grinder also includes a holding device for holding the wheel cover on the housing such that the arrangement and position of the wheel cover around the spindle can be changed but such that the wheel cover is not readily removable from the housing.
