Abstract
Electric scissors comprise a motor, a movable blade, a transmission mechanism, an operation device, an operation signal output device, a control device, a drive circuit, and a forced stop device. The forced stop device is configured to stop the motor when an abnormal state is present in which the value of the operation signal output from the operation signal output device is a value determined in the control device to rotate the motor in a specific rotation direction out of the first and the second rotation directions or to stop the motor, and in which the motor is rotating in a direction opposite to the specific rotation direction.
