Abstract: An image forming apparatus such as a printer and a copier has rotating devices such as a drum and a press roller to print an image on a paper sheet while rotating and a paper-transporting mechanism having guide rollers and timing rollers for transporting a paper sheet to these rotary devices, controlled by a control device such that irregularities in the printed images due to fluctuations in the speed of transportation of the paper sheets. The guide rollers may be operated to transport the paper sheet at a faster speed than the paper sheet is transported by the rotary devices such that the paper sheet becomes bent before being delivered to the rotary devices to be printed on. The control may be such that the guide rollers transport the paper sheet while the timing rollers downstream is released from the transportation of paper sheets. The control device may also operate so as to stop the guide rollers when the paper sheet comes to a position where the rotary devices can start transporting it.

Abstract: A sampling system arranged such that a modulated signal received by an antenna and input via a low noise amplifier and a band-pass filter is sampled at a sampling frequency higher than the signal band of the modulated signal by a first sample and hold circuit and is input to an analog decimation filter to remove a frequency component which may turn out to be aliasing noise. The output of the analog decimation filter is sampled with a sampling frequency lower than the sampling frequency of the first sample and hold circuit by a second sample and hold circuit and is digitized by an A/D converter to be demodulated by a demodulator. The sampling system which can convert the modulated signal into a low frequency without using the highly precision mixer circuit or a filter having sharp characteristics may be provided by constructing as described above.

Abstract: An individuality discriminating system wherein analog signals of a human individual picture are converted to digital signals according to brightness of the picture, and such digital signals are stored as individual picture data in an integrated-circuit (IC) card as compressed, with picture elements other than changed ones in the picture treated as zero picture elements, while in using the IC card by its bearer the thus stored data are read out of the card as expanded and analog-converted for display on a monitor. Since the picture data are compressed to remarkably reduce code volume upon the storing in the card, the individuality discrimination can be realized practically precisely and effectively reliably through an investigators's comparison with eyes of the thus displayed picture with a directly viewed or monitored picture of the bearer.
