  • Patent number: 4750731
    Abstract: In a serial connection of plural sheet sorters, each sorter is capable of checking the state of downstream sorters and, in case an assigned sorter is not in a normal state, the sheets are stored in an immediately preceding sorter. In this manner it is made possible to prevent a situation where the function of the entire sorters is blocked by a single failure. Also sorters of desired number can be connected in series since same control circuits can be used in all sorters.

  • Patent number: 4323297
    Abstract: In a semiconductor laser optical system which uses a light source a semiconductor laser having different diverging points and divergence angles in orthogonal directions and in which the light beam from the light source is imaged on a scanned surface, only a spherical surface optical system is provided between the semiconductor laser and the scanned surface. The spherical surface optical system includes two partial optical systems, i.e. a first image forming optical system and a second image forming optical system as viewed from the light source side. By selecting the optical constant of one of the two image forming optical systems to a predetermined value, the peak power of the image forming spot on the scanned surface is maximized.

  • Patent number: 4251125
    Abstract: An optical system for scanning is disclosed which comprises an afocal optical system and a first - and a second deflecting members so disposed respectively at an optically conjugate position relative to the afocal optical system as to substantially interpose the system therebetween. The plane formed by a beam deflected by the first deflecting member is substantially coincident with that formed by a beam deflected by the second one. In order to control the angle of deviation (deflection) of the beam finally scanned, there is provided, for the afocal optical system, means for differentiating the exit angle from the incident angle of a beam passing through the afocal optical system. Furthermore, the angle of deflection of a beam deflected by the first deflecting member in a unit time period is made different from that deflected by the second one.
