    摘要: A paper conveying apparatus which facilitates increased printing speed in a printer, such as a laser printer, by providing rollers which are rotated at different respective speeds at different times during a paper feeding and image transfer operation, so as to provide even feeding of the paper to an image transfer device. The paper is fed, one sheet at a time, relatively rapidly to the image transfer device, and at a slower speed, in synchronism with the image transfer operation, while transfer is being effected.

    摘要: The subject of the disclosed art is to prevent a short circuit between plural electrodes caused by soldering in the assembling process for a semiconductor laser element. The constitution for improving the subject is as follows. A semiconductor laser device comprises a semiconductor laser chip having a first electrode and a laser sustaining material, in which the laser sustaining material has electrodes and solder layers connected electrically therewith on the surface where the semiconductor laser chip is mounted, the first electrode of the semiconductor laser chip is connected with the solder layer of the laser sustaining material and at least the solder layer of the laser sustaining material extends from at least one end face in the longitudinal direction of an optical resonator of the semiconductor laser chip to the outside of the optical resonator.
