It is an object of the invention to provide a technique for further improving the vibration reducing performance in the power tool, while avoiding complicating the construction of the power tool. According to the present invention, a representative power tool may comprise a striker, a tool bit and a vibration reducer. The vibration reducer serves to reduce vibration on the striker by reciprocating in a direction opposite to the reciprocating direction of the striker. The path of the center of gravity of the vibration reducer is arranged to coincide with a path of the center of gravity of the striker. With such construction, because rotating moment is not exerted onto the reciprocating cylinder during the operation of the power tool, vibration reduction can be performed in a stable manner.

An actuator is arranged in a housing of an electrical nail gun. The actuator includes a sliding base, an external-running brushless direct current motor, a swing base and an electric driver. The sliding base is slidably disposed on an end of a located supporter which is positioned in the housing. The sliding base loads a spring and forms a hitting nail bar thereon. The motor has a stator and a rotator attached on an outer wall of the stator. A flywheel is driven by the motor and is configured to engage or disengage with / from the sliding base. The swing base is pivotally mounted on the housing. The swing base is adjacent to the sliding base and the supporter. The motor is installed in the swing base. The electric driver is attached to the housing and is adjacent to an end side of the swing base. The electric driver has a rod member driven by electricity. The rod member drives the swing base to swing to a first position where the flywheel meshes with the sliding base to thereby drive the sliding base to move downwards, and a second position where the flywheel disengages from the sliding base to thereby cause the sliding base to reposit. It is advantage to simplify the configuration of the actuator for the flywheel and is useful for the miniaturization of the electrical nail gun.

When a developer cartridge is mounted together with a drum unit in a main body casing, a detection gear is rotated by driving of a motor, and an abutment projection of the detection gear is brought into abutment against a lever of a drum subunit to move the lever.

Therefore, the information on the developer cartridge can be judged with a simple construction at reduced costs. Further, the developer cartridge can be mounted in the main body casing in spaced relation, so that the design flexibility is increased.
