ABSTRACT:
A mode selection device of a tape deck includes a power cam driven by a drive gear, a power plate moved by the power cam, first pin formed on the power plate, a key plate configured to engage the first pin when an attraction solenoid attracts a plunger plate and disengage it otherwise, a head plate linked to and concurrently movable with the key plate via a key plate link, a reverse link pivoted by second pin formed on the power plate; and a reverse link responsive to the movement of the head plate to engage or disengage third pin formed on the reverse link. The device is characterized in that the power plate is limited in its withdrawal when the plunger plate is attracted by the solenoid, and in the limited withdrawal of the power plate, the power cam is maintained at an angular position where a non-toothed portion of the power cam is opposed to the drive gear, so that the on and off action of the solenoid in combination with the different positions of the head plate establishes plural tape transport modes.
