A fastening tool includes: a bit holding portion which detachably holds a driver bit and is configured to rotate in a circumferential direction of the driver bit and move in an axial direction of the driver bit; a motor configured to move the bit holding portion along the axial direction; and a control unit configured to control a position of the bit holding portion along the axial direction by the number of rotations of the motor. The control unit is configured to execute an initialization operation of setting a standby position of the bit holding portion along the axial direction, and control a position of the bit holding portion along the axial direction from the standby position by the number of rotations of the motor.

Fastening tool

A fastening tool includes: a bit holding portion which detachably holds a driver bit and is configured to rotate in a circumferential direction of the driver bit and move in an axial direction of the driver bit; a motor configured to perform at least one of rotation of the bit holding portion and movement of the bit holding portion along the axial direction; and a control unit configured to control a position of the bit holding portion along the axial direction by a rotation amount of the motor. The control unit is configured to stop rotation of the motor based on a load applied to the motor rotated in one direction of moving the bit holding portion in a direction approaching a fastening target.

A fastening tool includes: a cylindrical rotation guide member extending in one direction and rotatably supported; a holding member having an opening in which a driver bit is detachably inserted, and configured to move in an axis direction along the extension direction of the rotation guide member inside the rotation guide member and to rotate together with the rotation guide member; and a moving member configured to move the holding member in a front and rear direction along the rotation guide member; a rotation member; and a transmission member connected to the moving member and having flexibility to be wound along an outer periphery of the rotation member. The rotation member is rotated by the motor, so that the moving member is moved with the transmission member in one direction in which a screw engaged with the driver bit is pressed against a fastening target.

A fastening tool including a bit holding unit configured to hold a driver bit so as to be rotatable and to be movable in an axis direction, a first drive unit having a first motor configured to rotate the driver bit held by the bit holding unit, and a second drive unit having a second motor configured to move the driver bit held by the bit holding unit along the axis direction.

The control unit is configured to control a moving speed of a screw moved by rotation of the first motor or a rotation speed of the first motor.

Captured or input image data is converted into an image of a size of a specific number of pixels. Then, predetermined plural types of different effects are applied to image data obtained through the conversion. Several types of image data items with the applied effects are arranged and simultaneously displayed.

Terminal device, image display method, and storage medium

A hand-held tool, in which multiple fasteners are successively fed, is provided with: an ejection detecting portion for detecting an ejection of the fasteners; and a control portion for switching from a power saving wait mode of small power consumption to an active mode capable of executing normal processing when the ejection detecting portion detects the ejection of the fasteners, and for switching from the active mode to the wait mode when the normal processing is ended.

Hand-held tool, fastener residual quantity detecting mechanism, fastener residual quantity detecting method, and power saving method

An electric power tool 'A' operates a working partby repeating rotation of a motorin a normal direction and in a reverse direction one or more times. The motorincludes a brushless motor. Sensors H for detecting a position of a rotorare provided on the motorso as to be advanced by an electrical angle of 30&#xb0;&#xb1;&#x3b8;&#xb0; from an intermediate position between respective stator teethin a direction of the normal rotation of the rotor. A control partfor controlling the rotation of the motorcontrols a driving signal of the motorbased on the results of detection by the sensors H. Moreover, the control partselects a detection signal of the sensors H so that relation between the rotorand the detection signal of the sensors H is equivalent in either of the normal rotation and the reverse rotation of the rotor
