Abstract

PURPOSE:To hold a loading disk at an invariably normal position by transmitting the rotating force of a motor less loaded one of a loading gear and a mode cam means by using a differential gear mechanism when transmitting the rotating force to the both. CONSTITUTION:The rotating force of a loading motor 101 is transmitted to a loading disk 11 through a sun gear 107, planet gears 114 and 115, etc., and on the completion of loading, a load increases, thereby transmitting it to a mode cam gear 120. The mode cam gear 120 has a load part 177 formed in front of a recording and reproducing command position 173 so that the load on the tracing pin 182 of a cam arm 180. When this part 177 is traced, the speed of the mode cam gear 120 is reduced temporarily and the force equivalent to the resultion is applied to a planet gear supporting device. Therefore, a loading gear is driven by one or two pitches to correct the incomplete setting of the loading disk.
