摘要： A single sided servo apparatus comprises a linear motor and a longitudinal carriage which is connected to the linear motor at one end thereof. The linear motor comprises a stator including field magnets arranged linearly and a movable piece including armature coils. The field magnets have a trapezoid-like magnetic flux distribution. An arrangement pattern of the field magnets has a relative tilted angle to an arrangement pattern of the armature coils, so that a free end of the carriage precedes the other end thereof connected to the linear motor. Then, the thrust has a small variation and generates a stable thrust of the servo apparatus.

摘要： A reader printer is disclosed which incorporates therein a scanning plane mirror for projecting an image in the form of a slit on a sensitive material. The sensitive material is shifted proportionately to the rotation of the scanning mirror so that the position at which the image is projected on the sensitive material will coincide with the scanning position of the sensitive material. As a result, the otherwise possible phenomenon of defocusing is precluded and the image is faithfully reproduced on a recording paper. The mechanism for rotating the scanning mirror and the mechanism for shifting the sensitive material are divided to allow production of a reader printer of a small size.
