Abstract

The type wheels provided on a postage or franking head of a postage meter or franking machine are adjusted in stepwise manner from outside the franking head by means of adjusting push rods, which in each case engage a pinion associated with a type wheel. The engagement and adjusting movement of the adjusting push rod is performed by electromagnets. The engagement movement takes place by pivoting a guide plate carrying the adjusting push rods, on which the rods are displaceable by means of the electromagnet counter to the tension of a tension spring. The electromagnets can be energized on the basis of an electrical pulse, which is simultaneously used for adjusting an electronic display, provided on the franking machine casing.
