摘要： An apparatus for determining the dimensions of a stack of sheets in the tray. An optical sensor is arranged so that movement of the sheet guides in a paper tray causes a variably graduated scale to be moved past the sensor. The sensor may either be a transmissive or reflective type analog sensor in which the strength of the signal generated by the sensor is converted into a position of the side guides and as the analog scale is continuously variable, there is no need for separate discrete sensors or switches and sheet sizes of any dimension can be accommodated. A recalibration process is used to prevent contamination of the gauge and the associated change in signal strength by this sensor from causing the size determinations to be inaccurate. Alternatively, a digital sensor in cooperation with a digital bar code or other digital scale can be utilized to determine the variable sheet size, which digital sensor and variable scale are insensitive to contamination by dirt or paper particles, etc. The sensor system herein is very robust and provides a simple device for determining the size of a stack of sheets in a paper tray.

摘要： A motor speed control system for reducing instantaneous speed variations as a result of hunting in hysteresis synchronous motors utilized to drive optical scanners by controlling the frequency of the drive signal applied to the motor. A laser beam is reflected from the facets of the optical scanner and scans a surface along a scan line, a signal being generated at the start and end of each scan line. A counter is driven by an accurate clock which is started and stopped in accordance with the start and end of scan signals. The resulting count of the counter is thus inversely proportional to the speed of the motor and is converted to an analog input signal and coupled to a voltage controlled oscillator whose frequency is controlled for driving the motor such that undesirable oscillations of the motor are damped out. Additional embodiments for controlling the motor speed are disclosed which utilize only the start of scan signal to both start and stop the counter.

摘要： An apparatus for displaying a plurality of two dimensional display regions includes a currently displayed display region on a surface of a visual display. A pointing device generates X and Y coordinate signals corresponding to locations on the display and a Z increment signal, and a pointer is displayed on the display at a location corresponding to a set of the X and Y coordinate signals. A sequence of two dimensional display regions is stored in a memory circuit, and a display region succeeding the currently displayed display region in the sequence or a display region preceding the currently displayed display region in the sequence is selected in response to the Z increment signal irrespective of whether the location at which the pointer is displayed coincides with the selected display region. The display regions are displayed on the display in accordance with the sequence such that the selected display region appears as the currently displayed display region, and display regions succeeding the selected display region in the sequence appear overlapped by the selected display region in a third dimension normal to the surface of the display with each of the displayed display regions being displayed in its entirety except where overlapped by a preceding display region in the sequence. The selected display region is displayed in its entirety.

摘要： A high speed color reproduction machine comprised of four separate xerographic type processing units, one for each of the primary colors plus black. The multiple processing units are arranged in close nested relationship to one another with the image transfer stations thereof in close succession along the path of movement of the copy substrate material. A combination air flotation type and vacuum based belt transport system is employed to bring copy substrate material from a supply source into transfer relation with the successive processing units. Exposure of the processing unit's photoreceptors is simultaneous. A precise dimensional relationship between photoreceptor length and spacing for each processing unit assures registration of the color images produced with one another. Following transfer of the last color image, the image bearing copy material is brought to a fuser where the image is fixed. The finished copy is thereafter discharged, or returned for a second duplex pass. The photoreceptor of each processing unit comprises an endless photoconductive belt. The length of each photoconductive belt is the same. Vacuum tensioning is employed with each belt to provide preset belt lengths between exposure and transfer stations for each processing unit. A flying spot type exposure system is used with laser light source and optical elements to simultaneously project independent image exposure beams to the exposure stations of the several processing units.

摘要： A binary ink drop printer is disclosed of the type wherein continuously generated drops are electrostatically deflected to intersect either a target or a gutter. The printer includes M.times.N number of nozzles for generating drops and a like number of charging electrodes for charging drops to either a print level for flight to the target or a gutter level for flight to a gutter. A M.times.N matrix is used to couple voltages to the charging electrodes and thereby greatly reduce the number of electrical connections to a substrate carrying the M.times.N number of charging electrodes. Each charging electrode includes two sections. Application of a print voltage to both sections causes the generation of a print drop that goes to the target and application of a gutter voltage to either or both sections of the charging electrode causes the generation of a gutter drop that is collected in the gutter. One two section electrode is made using at least two partial cylinders. Another two section electrode is made by coupling a single electrode to a voltage divider network.
