摘要： A cutting machine of the present invention for cutting a material to be cut, which is placed on a table, with a rotating saw blade, includes an imaging device, a determination device and a stopping device. The imaging device takes a video image of an area on the table and outputs the video image. The determination device makes a determination on whether or not a number of pixels of a specific color, which is previously set, exceeds a predetermined threshold in one frame of image constituting the video image outputted from the imaging device. The stopping device stops rotation of the saw blade when it is determined by the determination device that the number of pixels of the specific color exceeds the predetermined threshold.

摘要： An electric power tool is provided that includes a motor as a driving source, a first operation switch, a first semiconductor switch, and a second semiconductor switch. The first operation switch is operated by a user to be turned ON/OFF. The first semiconductor switch, provided on a current path from the power source to the motor, includes at least one semiconductor switching device. When the first operation switch is OFF, the first semiconductor switch is turned OFF to interrupt the current path. When the first operation switch is ON, the first semiconductor switch is turned ON to close the current path. The second semiconductor switch is provided on the current path in series with the first semiconductor switch and includes at least one semiconductor switching device. The second semiconductor switch closes/interrupts the current path by being turned ON/OFF in accordance with an input control signal.
