Inventor: SCHOENMAKERS JOHANNES JOSEPH M
IPC: G11B15/10
Filed: 1981-10-30
Granted: 1984-03-01
Abstract: An apparatus for recording and/or reproducing signals on a magnetic tape is provided with two reel discs (97, 98; 160, 161), at least one magnetic head (17, 18; 165, 166) which is arranged on a head slide (19; 164, 194), a pressure roller (137; 180) arranged on a pivotable pressure-roller arm (135; 179) and which is movable against a capstan (96, 185), a central drive wheel (83; 157) which is rotatable in two directions and which, via normal-mode and fast-mode idler wheels (84, 169 and 91; 159 respectively) carries on pivotable arms, can drive the reel discs, and a pivotable switching lever (114, 176, 206) which is adapted to be coupled to the pressure-roller arm, the fast-mode idler arm and the normal-mode idler arm and to brake arms (104, 105; 171, 173). 
<??>Depending on the direction of rotation of the central drive wheel the fast-mode idler arm is pivoted from an inoperative position into a first or second operative position respectively. In a first position control means which are adjustable to two positions limit the pivotal movement of the switching lever to movement into a first, partly pivoted operating position. in which first position of the control means the fast-mode idler arm is uncoupled from the switching lever so that the fast-mode idler arm is pivoted. In the second position of the control means the switching lever is pivotable into a fully pivoted second operating position, the fast-mode idler arm then occupying the inoperative position through the coupling of the fastmode idler arm with the switching lever and the normal-mode idler arm being pivoted into the operative position. In both operating positions the switching lever is also coupled to the head slide.
