Abstract
An operation changing mechanism for a tape recording/reproducing or other electronic apparatus includes a reversible electric motor for selectively rotating a driving gear in opposed directions, a first swinging gear engaged with the driving gear and rotatably coupled to a co-axial second swinging gear with the common axis of the first and second swinging gears being mounted for orbital movements about the axis of the driving gear between first and second limited positions to which the common axis is urged in reaction to rotation of the driving gear in the opposite directions, respectively, a rotary cam member with peripheral gear teeth engageable by the second swinging gear and having a toothless gap that accommodates the second swinging gear to halt turning of the cam member, the shifting of the common axis of the swinging gears from one to the other of the limited positions thereof in response to a change in the direction of rotation of the drive gear being effective to move the second swinging gear out of the toothless gap and into engagement with the peripheral gear teeth for again turning the cam member, an actuating member engaging a cam surface on the rotary cam member and being reciprocally moved thereby in response to turning of the rotary cam member for changing a respective operation of the electronic apparatus, and a locking device for holding the rotary cam member against inadvertent turning from each position in which the second swinging gear is accommodated in the toothless gap.
