A compact radio equipment includes internal circuits on two or more printed circuit boards electrically connected to each other and securely mounted in structure. When a time interval is longer than a preset time, the controller can control the power supply unit not to apply the bias voltage when the printing paper is not placed in the nip, and when the time interval is shorter than the preset time, the controller can control the power supply unit to apply the bias voltage when the printing paper is not placed in the nip. The outer tube can be displaced in the axial direction of the cutting tube, which is immovably fixed to the manipulator, against the force of a pressure spring between an initial position in which the outer tube projects beyond the cutting tube on the distal side and a working position in which the blade protrudes from the distal end of the outer tube. The triglyceride has at least one acid component with 6 to 30 carbon atoms and at least one epoxy group for reacting with the carboxyl groups. A user is provided with a capability to correct erroneous or questionable words so as to improve the quality of translation.
