摘要： A counting apparatus comprising a drum counting mechanism and a step motor for driving the drum counting mechanism. A housing for the drum counting mechanism includes a wall which forms a part of the housing for the step motor, the step motor including a rotor with a rotor shaft, which shaft extends through the wall. The step motor includes a stator coil which is supported on an extending portion of the housing for the step motor. Alternatively, a bearing and flange unit may be provided which extends through an opening in the common wall and which may have an extending portion on which the stator coil is mounted in surrounding relationship.
