摘要： A disc driving apparatus includes a recording and reproducing unit for recording or reproducing an information signal for a disc-shaped recording medium having a printing surface and a print unit for performing printing to the printing surface of the disc-shaped recording medium. The print unit includes a print head which is pressed to the printing surface when printing is performed on the printing surface, a head feeding unit to which the print head is mounted, the head feeding unit moving along the printing surface of the disc-shaped recording medium, and a guide member for guiding the movement of the head feeding unit. When the print head is pressed to the printing surface while printing is performed on the printing surface, the disc-shaped recording medium is bent so that the printing surface becomes inclined. The guide member is disposed to be inclined according to the inclined state of the printing surface.

摘要： If a bus current a bus current detector 11 detects exceeds a current cutoff value, an overcurrent detector 12 supplies a gate driver 14 with an open signal for turning off switching elements 5-10 to break the current to a motor 1. Besides, when the overcurrent detector 12 detects an overcurrent, a feedback controller 15 provides the gate driver 14 with a short-circuit braking instruction to apply short-circuit braking after breaking the power supply, and to restart PWM control from a state in which the short-circuit braking is being applied and the duty ratio command value is reset at 0.

摘要： A driving force transmitting devices is able to engage a main clutch with a small amount of hydraulic pressure. The driving force transmitting device includes an input shaft and an output shaft, and a main clutch. The device is formed of a primary clutch that intermittently transmits the driving force transmitted from the input shaft, a hydraulic pump that generates a hydraulic pressure, a piston that presses the primary clutch with the hydraulic pressure by the hydraulic pump, and a cam mechanism that presses the main clutch with a press-contact force which is amplified to be larger than the press-contact force of the piston by utilizing the driving force from the input shaft through the primary clutch, so as to engage the main clutch.
