摘要： A drum for an image recording apparatus for absorbing and winding a recording material for the purpose of recording the image of an exposure head thereof. The main body of the drum is structured by arranging a plurality of cylindrical members having a relatively smaller axial direction. Since the drum is formed by arranging the cylindrical members, the drum can be readily manufactured. A guide is provided on the outer surface of the drum, this guide guiding, pressing, and retaining the front portion of the recording material to the outer surface of the drum so that the absorption of the recording material is conducted assuredly. The shaft of the drum is borne by a radial ball bearing which has a sealing member so that air leakage when the absorption is conducted is prevented.

摘要： A method and apparatus for assuring proper park positioning of a sheet gripper device. A reference signal is generated by a master control board causing the sheet gripper to commence its movement along the belts of a sheet transport system. An index marker and encoder coupled to a servo motor generate pulses based on the rotation of the shaft of the servo motor. A registration control board coupled to the servo motor generates an index interrupt after receipt of a predetermined number of pulses from the index marker. The number of rising and falling edges of a system clock that occur between the generation of the reference signal and the index interrupt is computed by the registration control board and sent to the master control board. The master control board compares this distance value to a predetermined resynchronization value. Based on the discrepancy between the two values, the master control board recalculates a park position value which is sent to the registration control board. The park position value is the amount of time that elapses after the sheet gripper has passed a gripper home sensor. Thus, recalculation of the park position value insures accurate park positioning prior to the performance of each job.
摘要翻译：一种用于确保纸张夹持装置的适当驻车定位的方法和装置。参考信号由主控制板产生，使得纸张夹持器开始沿着纸张传送系统的传送带移动。耦合到伺服电动机的指示标记和编码器基于伺服电动机的轴的旋转产生脉冲。耦合到伺服电动机的配准控制板在从索引标记接收到预定数量的脉冲之后产生指标中断。在参考信号的产生和索引中断之间发生的系统时钟的上升沿和下降沿的数量由注册控制板计算并发送到主控制器。主控板将该距离值与预定的再同步值进行比较。基于两个值之间的差异，主控板重新计算发送到注册控制板的停放位置值。公园位置值是纸张夹持器通过夹具本地传感器之后经过的时间量。因此，重新计算停车位置值可确保在执行每个作业之前进行准确的驻车定位。

摘要： An image recording apparatus for recording an image on a heat-sensitive recording material which has on both sides of a transparent support member a plurality of transparent heat-sensitive color developing layers that develop respective colors in different hues from each other. The image recording apparatus includes a reversing device for turning the heat-sensitive recording material upside down, after the transparent heat-sensitive color developing layer on one side has been heated to develop the color. Accordingly, color development for both sides of the heat-sensitive recording material can be automatically performed.An image recording method for recording an image by a recording head on a heat-sensitive recording material which has two sorts of dye layers on one side and one sort of dye layer on the other side. The image recording method comprises the steps of color-developing one of the said two sorts of dye layers on one side, irradiating light onto the color-developed dye layer to fix the developed color, turning the heat-sensitive recording material upside down, while irradiating the light onto the color-developed layer, and then color-developing the dye layer on the other side.Accordingly, a longer fixing time can be set to ensure the positive fixing.

摘要： An electrophotographic printer having a photosensitive drum disposed in a body for transferring an electrostatically adhered toner to the lower surface of a sheet, a fixing unit disposed at the downstream side of the photosensitive drum for fixing the toner transferred to the sheet, and a suction conveying mechanism disposed between the photosensitive drum and the fixing unit for conveying the sheet transferred with the toner by the photosensitive drum by sucking the sheet transferred with the toner from above comprising a retaining roller rotatably pressed in contact with the lower surface of the conveyor belt of the suction conveying mechanism. Thus, the printer can positively and stably convey a sheet of all types including an envelope toward the fixing unit when the sheet transferred with a toner image to its lower surface is conveyed while the sheet is sucked from the upper surface.

摘要： A facsimile transceiver unit utilizing a drum wherein a drum gripper bar grips an edge of a sheet to be scanned during system operation. On termination of operation, the drum direction is reversed allowing the beam strength of the scanned sheet to lift the free edge of the sheet off the drum. The sheet is then picked off by a suitable member and directed out of the facsimile transceiver unit. At the same time, the gripper bar is opened releasing the sheet for easy operator removal. In a preferred method, the sheet is bumped by the raised gripper bar to ensure release of the sheet from the facsimile transceiver unit.
