A recording-medium transfer device having a anti-rattle construction is provided. A transfer roller 6 of the recording-medium transfer device is arranged above a chassis 5 to be perpendicular to a direction X of transferring recording medium. The transfer roller 6 has a structure in which a shaft is inserted in rolling member made of a material having flexibility. Projecting portions 13 and 14 are formed on the chassis 5 to oppose to both ends of the rolling member. In both ends of the rolling member, clearances are respectively formed to permit the deformation produced by its abutment with the projecting portions 13 and 14. In the process for inserting the disc, the projecting portions 13 and 14 are moved away from the transfer roller 6. Upon receiving a driving force from a driving motor 7 and gears 8 to 11, the rolling member of the transfer roller 6 is rotated keeping in contact with the disc so as to transfer the disc toward a clamping position. When the transfer of the recording medium is completed, both ends of the rolling member press on the projecting portions 13 and 14, thereby the transfer roller 6 is fixed to the chassis 5 so as to prevent chatter due to outside vibration from occurring.

摘要:
Liquid to be injected from an injection nozzle is supplied through a liquid supply channel toward the injection nozzle. Negative pressure for sucking the liquid injected from the injection nozzle through a suction port is produced by a suction unit and guided through a suction channel toward the suction port. A bypass channel which bypasses the liquid supply channel on the upstream side with respect to the injection nozzle and connects with the suction channel is provided. The bypass channel is opened and closed by an opening and closing unit. According to this structure, flow of unnecessary liquid from the injection nozzle can be reduced by opening the opening and closing unit while injection of liquid is stopping.

According to an embodiment, a transmission apparatus is installed in a locomotive having ID information. A first connecting direction and a second connecting direction opposite the first connecting direction are defined for the locomotive. The transmission apparatus includes a transmission unit and a connection state determination unit. The transmission unit transmits the ID information received from other locomotive from one of the first connecting direction and the second connecting direction to other one of the first connecting direction and the second connecting direction. The connection state determination unit determines a connection state between the other locomotive and the locomotive in which the transmission apparatus is installed, based on the received ID information.

A control device includes a first terminal receiving a monitored output voltage and a second terminal transmitting a pulse width modulation (PWM) signal. A converting unit generates an A/D conversion synchronous signal, and an A/D converter samples the monitored output voltage in accordance with the A/D conversion synchronous signal. A pulse oscillator controls a position of a first edge on the PWM signal in accordance with the A/D conversion synchronous signal, and controls a position of a second edge based on the monitored voltage.

A power supply controller includes an analog to digital (A/D) converter that performs analog-digital conversion of an output voltage and outputs a digital signal, a deviation signal generator unit that generates a deviation signal from the digital signal and a standard voltage value serving as an output voltage target value, and a power controller unit that controls the output voltage based on the deviation signal. The power supply controller includes a conversion range setting unit that sets a range of the reference voltage into the A/D converter based on a first signal as the digital signal in a power supply startup period, and sets the reference voltage range into the A/D converter based on a second signal as the deviation signal or as a signal corresponding to the deviation signal in a steady state period.
