It provides a reinforcing bar binding machine that allows binding objects such as reinforcing bars to be bound by wires with end portions of the wires directed to the binding object side. The reinforcing bar binding machine (1A) includes: a magazine (2A) in which two wires (W) are housed in a drawable manner; a curl guide unit (5A) that winds the juxtaposed wires (W) around the reinforcing bars (S); a wire feeding unit (3A) that winds the wires (W) around the reinforcing bars (S) with the curl guide unit (5A) in an operation of juxtaposing and feeding the wires (W) and winds the wires (W), which is wound around the reinforcing bars (S), around the reinforcing bars (S); and a binding unit (7A) that twists crossing portions of one end side and the other end side of each of the wires (W) wound around the reinforcing bars (S). The binding unit (7A) includes a bending portion (71) that bends the one end side and the other end side of each of the wires (W), which are wound around the reinforcing bars (S), toward the reinforcing bars (S).

There is provided an electric power tool including: an electric motor; a first battery; a second battery; a first controller configured to control the electric motor at a first operating voltage supplied based on a first power supply voltage supplied from the first battery; a communication device; and a second controller configured to control the communication device at a second operating voltage supplied based on the first power supply voltage supplied from the first battery, and configured to control the communication device at the second operating voltage supplied based on a second power supply voltage supplied from the second battery when the first power supply voltage is not supplied from the first battery. The second controller is configured to execute a reset operation when a predetermined condition is satisfied.

A screw driving machine includes a driving piston to which a driver bit is attachable, a driving cylinder partitioned into a first chamber and a second chamber by the driving piston and moving the driver bit when compressed air is supplied to the second chamber, an air motor rotating the driver bit by the compressed air, an air flow path communicating the second chamber and the air motor, a main chamber storing the compressed air and communicating with the air flow path, and a main valve opening and closing communication between the air flow path and the main chamber. The driving cylinder has a supply port communicating the air flow path and the second chamber. A throttle portion is disposed to be displaceable on an outer periphery of the driving cylinder to change an opening area of the supply port.

A handheld tool includes a nose portion having an injection passage for a fastener, a magazine accommodating the fastener and located in a direction intersecting with the injection passage, a magazine cap portion opening and closing the magazine by a tip portion rotating in a direction separating from and approaching the magazine with a base end portion as a fulcrum, and a door portion rotatably coupled to the tip portion via a coupling shaft. The nose portion includes an engaging portion engageable with the door portion. The door portion is configured to, in a state where the magazine cap portion is opened, bent toward the magazine with the coupling shaft as a fulcrum, and in a state where the magazine cap portion is closed, extend linearly and engage with the engaging portion.

A staple removing device includes a placement portion having a placement surface on which a paper bundle bound by a staple is to be placed, a rotating shaft, and a removal unit attached to the rotating shaft and rotating along a surface intersecting an axial direction of the rotating shaft. The removal unit includes a tip portion to be inserted between a lower surface of the paper bundle placed on the placement surface and a crown portion of the staple, a middle portion connected to the tip portion and having an action surface to be in contact with the crown portion, and a base portion connected to the middle portion and the rotating shaft. An upper surface of the base portion is located on the same plane as the placement surface or below the placement surface.
