ABSTRACT:
A mode changing apparatus for a tape recorder to initiate a change in mode including a loading gear having at least a portion magnetized in N and S poles and an electromagnet adjacent to the magnetized portion of the loading gear. When a trigger signal is applied to the electromagnet responsive to the selection of a mode of operation for the tape recorder, the loading gear is brought into meshing engagement with a drive gear. The drive gear is driven and disposed so it does not mesh with the loading gear until the electromagnet is energized. Once the electromagnet is energized to engage the drive gear and loading gear the rotation of the loading gear effects the mode change of the tape recorder.
