Abstract: In a Manchester encoded data decoder a clock component is extracted from input data inputted at a prescribed rate, the extracted clock component is taken as input and transition points are extracted from the signal waveform of the filter output, a clock signal of the same rate as the input data and which is in synchronism with the phase of the extracted transition points is generated, a data component is extracted from the input data, results of comparing the extracted data component and a prescribed value are outputted as a binary level signal; and the binary level signal, taken in using the clock signal, is outputted as NRZ encoded data corresponding to the input data.

Abstract: An image generating device is provided with a control mechanism which controls an exit paper delivery speed after an image has been fixed to a form. The exit paper delivery speed is changed depending on information detected about the process of generating the image to prevent the form from being delivered with wrinkles. The information detected includes size of paper intervals between forms, length of forms, and whether the image generating process is a repeat copying or continuous form feeding process.

Abstract: A heat roller type fixing device for an electrophotographic copier, printer, facsimile apparatus or similar electrostatic image recorder includes a hollow cylindrical fixing roller having a heating element thereinside and a hollow cylindrical pressing roller held in pressing contact with the fixing roller. A shaft is received in the pressing roller while two annular pressing members are mounted on the shaft through individual bearings so as to urge the cylindrical inner periphery of the pressing roller. The pressing members are each movable on and along the shaft to any predetermined distance as measured from an end of the pressing roller.

Abstract: A heat roll type fixing arrangement for fixing a toner image on a paper includes an inlet guide plate which constitutes a lower guide plate for guiding the paper toward a nipping section of a fixing roll pair. Two ribs are provided in a central portion of a guide surface of the guide plate with respect to the widthwise direction of the guide surface. The front end of the guide plate is notched at opposite sides of the central portion such that it is sequentially inclined toward opposite side edges of the guide plate while sequentially approaching the nipping section. The guide plate is so arranged as to position the highest point of the tip of each rib which is closest to the nipping section in a predetermined spatial range.
