OPERATION STATUS SWITCHING DEVICE FOR MAGNETIC RECORDER AND REPRODUCING DEVICE

摘要

PURPOSE:To prevent generation of impact force at the time of start of switching operation to increase the reliability on operation by adopting a differential retation mechanism for clutching procedure and making a clutch operate only by restriction of the rotation of a rotating body. CONSTITUTION:Respective operation parts 41 to 45 prepared for switching the operation status of a magnetic recorder and reproducing device in operation part group 40 are operated by corresponding operation buttons in operation button group 64. The rotation of driving motor 56 is reduced and transmitted to input shaft 60 in order to move the driving lever through the differential rotation mechanism including 2 rotation bodies 82 and 84 and switch the operation status of the corresponding part in operation parts 41 to 45. The differential rotation mechanism prepared for a clutching procedure equips the clutching procedure and restricting procedure in every pair of the clutching procedure and operation button 1, and it restricts one rotating body and transmits the turning force from the input shaft to the other one to switch the operation status by means of the turning force.
