    摘要： A direct-conversion receiver includes a local oscillator for generating a local oscillator signal, a converter circuit for converting a received radio signal into a pair of a baseband I signal and a baseband Q signal in response to the local oscillator signal, a demodulator for demodulating the pair of the baseband I signal and the baseband Q signal into a demodulation-resultant signal which is neither an I signal nor a Q signal, a detector circuit for detecting a difference between a frequency of the local oscillator signal and a frequency of a carrier of the received radio signal, a clock signal generator for generating a first clock signal providing a timing which corresponds to a center of a symbol period, a signal delay device for delaying the first clock signal to provide a second clock signal, and a symbol deciding circuit for deciding a logic state of the demodulation-resultant signal at a timing determined by the second clock signal.

The document transport device has a first belt roller disposed above a document positioning member. A second belt roller is disposed away from the first belt roller in the document transport direction. An endless belt is wound around the first and second belt rollers. Plural presser rollers are arranged on a specified position between the first and second belt rollers to press the belt against a contact glass. The document transport device has a tension roller between the first belt roller and the presser roller closest thereto to apply a tension force to the belt so as to set the belt at the lowermost position of the tension roller below a common tangential line to the circumferences of the first belt roller and the presser roller and apart from the contact glass.

    摘要： A recycle document feeder includes a partitioning unit (17) and action plates (19, 20). The partitioning unit (17) includes a partitioning bar (18). When the partitioning bar (18) is lowered, the leading edges of discharged document originals are stopped by the partitioning bar (18). The action plates (19, 20) guide the discharged document originals toward an upper side of the trailing edges of document originals yet to be fed, and push the trailing edges of the discharged document originals to transport the document originals for re-feeding thereof. The partitioning unit (17) and the action plates (19, 20) are driven by a common motor (47). Further, a partitioning unit driving mechanism (110) and an action plate driving mechanism (111) are provided for driving the partitioning unit (17) and the action plates (19, 20), respectively.

    摘要： A paper conveying device for overrunning paper from a stop position and then, switching the paper back to stop the paper in a stop position. The driving of a paper conveying section for conveying paper is stopped at the time point where the rear end of the paper reaches the stop position. Thereafter, the amount of overrun of the paper is detected, so that the paper is switched back by the amount. Consequently, the amount of overrun and the amount of switchback of the paper are suppressed to the minimum amounts required. In addition, the stress applied to the paper is reduced, and the paper is set in a short time.
