Abstract
A recording and/or reproducing apparatus employing a tape cassette having a magnetic tape wound about a pair of tape reels includes a supply side reel block, a takeup side reel block, a capstan arbor, a driving unit and a switching unit. The supply side reel block rotationally drives a supply side tape reel and includes a supply side reel block gear portion. The takeup side reel block rotationally drives a takeup side tape reel and includes a takeup side reel block gear portion. A capstan arbor runs the magnetic tape. The driving unit selectively runs the supply side reel block gear portion and the takeup side reel block gear portion in rotation by engaging the gear portions with each other. The driving unit includes a driving source and an intermediate gear for transmitting the driving power from the driving source to the supply side reel block gear portion, takeup side reel block gear portion and to the capstan arbor. The switching unit switches an running state of the magnetic tape by the actuating member being thrust from its initial position. The actuating member is thrust for moving the intermediate gear along its axis of rotation for transmitting the driving power from the driving source to one of the supply side reel block gear portion and the takeup side reel block gear portion and to the capstan arbor.
