    摘要: An optical pickup emits a light beam onto a recording medium and outputs, in response to a reflection from the medium, a first and a second signal for controlling focusing servo control and tracking servo control, respectively. A signal generating section generates a focus error signal and a tracking error signal in response to the first and second signals, respectively. A driving section is responsive to the output of the signal generating section for outputting a first and a second drive current assigned to focusing and tracking, respectively. An actuator moves the pickup in a focusing direction and a tracking direction by the first and second drive currents, respectively. An adjusting section detects two values close to the maximum and minimum values of the tracking error signal at the start of the focusing servo control and adjusts the gain of the second signal on the basis of a difference between the detected values. Alternatively, the offset of the second signal may be adjusted by the sum of the two detected values. Futher, the offset of the first signal may be adjusted by a focus offset occurring when the amplitude of the first and second signals appearing after the start of the focusing servo control or the amplitude of a third signal also outputted by the pickup and representative of recorded data and appearing after the start of tracking servo is close to the maximum.

    摘要: An image forming apparatus may include controls for changing a state of a developing roller from a stopped state to a rotating state. The change in state may be used to avoid deterioration of toner and/or a surface of the developing roller. Changes in state may occur at various times including at a timing corresponding to an outside of an image formation area, a timing corresponding to an inside of an image formation area and the like. In one arrangement, a first developing roller may continue to rotate (e.g., during monochrome printing), while one or more other developing rollers are switched between a stopped state and a rotating state. Alternatively or additionally, a roller which is caused to change states may remain stopped between the timing corresponding to a rear end of an image formation area and a timing corresponding to a front end of an immediately subsequent image formation area.

    摘要: Provided is a fare box which enables passengers to smoothly pay fares using bills without hesitation even when a bill transportation passage is disabled due to jamming of a bill or a breakdown. Two entrances, which are a bill normal receiving opening and a bill backup receiving opening, are provided as bill receiving openings of the fare box. Either of the bill normal receiving opening and the bill backup receiving opening is allowed to be selectively opened by a shutter member. At normal times, the bill normal receiving opening is put into operation with the shutter member positioned at a normal position. When a bill normal transportation passage has become jammed with a bill, the shutter member is shifted from the normal position to a bypass position on the basis of an operation performed on a bill receiving opening switch lever, whereby the bill backup receiving opening is opened instead of the bill normal receiving opening.
