摘要： A control system for an optical sheet sensor device, including at least one light emitter and at least one light detector associated therewith for sensing a sheet in a sheet travel path, having a control system for automatically adjusting the intensity of said light from said light emitter. The control system stores a light emitter current level corresponding to a known valid operating condition where, when a sheet is absent from the sheet travel path, light detected at a light detector beyond a threshold level. A current level at a preset amount off-set from said stored current level is determined. A current is applied to a light emitter, the applied current rising toward a level at which the threshold level for the light detector is reached. The instantaneous applied current level is compared with the determined current level, and an error signal is provided when the applied current level reaches the determined current level. If the determined current level is not reached by the applied current level, the light emitter is operated at the applied current level, and if the determined level is reached, such error signal is provided.

摘要： A control system for an optical sheet sensor device, including at least one light emitter and at least one light detector associated therewith for sensing a sheet in a sheet travel path for automatically controlling the sheet sensor device in order to provide an intensity of light from the light emitter to compensate for varying background reflectance and background-to-light emitter distance. The control provided for determining a light emitter current level corresponding to an operating condition where a sheet is known to be absent from the sheet travel path and where there is a close, reflective background to the light emitter. A light emitter current operating level corresponding to a reduced level with respect to the above determined current level is stored. A current startup error level at a preset amount off-set from the stored current level is determined. Current is applied to a light emitter, the applied current being increased toward a level at which the threshold level for the light detector is exceeded. The instantaneous applied current level is compared with the determined startup error current level, and an error signal is provided when the light intensity threshold is reached prior to the applied current level exceeding the determined current level. If the determined startup error current level is exceeded by the applied current level prior to the light intensity reaching the light intensity threshold, the light emitter is operated at the applied current level.

摘要： An apparatus for diverting paper along at least two paper paths in photocopiers, the apparatus comprises a paper diverter for diverting paper from one path to another path. A magnet is attached to and moves the paper diverter which movement, in turn, permits the paper to be directed from one path to another paper path. Means for creating a magnetic field interacts with the magnet for permitting the magnet to move in response to the magnetic field for enabling the magnet to move the paper diverter for ultimately permitting paper re-direction.
