摘要： The present invention relates to a driving mechanism for turning a photosensitive drum in an electrophotographic copying machine, which is provided with a brake loading means to brake the turning force of the drum, and is characterized in that the brake loading means comprises a brake loading device for a power transmitting means arranged between the drum and a motor and a brake loading device for the drum.The former device applies a predetermined frictional braking force to the turning of at least one follower axis in the power transmitting means and eliminates adverse effects of backlashes existing between the motor and the follower axis with respect to the turning stability of the drum. The latter device eliminates adverse effects of backlashes existing between the follower axis and the drum as the same above.

摘要： A method and apparatus for reproducing a desired portion of letters and/or patterns in an original on a copying paper, wherein the system is computerized so as to obtain the necessary information from the data stored with respect to the distance components derived from the original, and on the basis of the information, an area excluding the desired portion of the original is deelectrified so as to exclude the area from the expected reproduction of the desired portion on the copying paper.
