Abstract: L'INVENTION CONCERNE UN DISPOSITIF DE CHANGEMENT DE MODE DE FONCTIONNEMENT. ELLE SE RAPPORTE A UN DISPOSITIF DANS LEQUEL UN PIGNON 1 DE CHANGEMENT DE MODE DE FONCTIONNEMENT A DES DENTS A SA PERIPHERIE SAUF DANS UN ESPACE 2. UN PIGNON MENANT 6 NE PEUT DONC ENTRAINER LE PIGNON 1 QUE LORSQU'UN COURANT ELECTRIQUE CIRCULANT DANS L'ENROULEMENT 15 A DECLENCHE LE PIGNON 1. UNE CAME 5 PORTEE PAR CE DERNIER DEPLACE UN LEVIER 22 QUI PERMET L'APPLICATION D'UNE ARMATURE 32 CONTRE UNE PARTIE 13 DE CARCASSE QUI TRANSMET ALORS L'ESSENTIEL DU FLUX MAGNETIQUE, SI BIEN QUE LE PIGNON 1 PEUT A NOUVEAU SE STABILISER. APPLICATION A LA COMMANDE DU MODE DE FONCTIONNEMENT DES MAGNETOPHONES.

Abstract: A mode changing apparatus for a tape recorder comprises a rotatable changing gear having a toothed periphery with a toothless gap therein, a magnet rotatably coupled with the changing gear for rotation therewith, a driving gear rotatably mounted for engagement with the toothed periphery of the changing gear, a yoke assembly including a portion cooperating with the magnet for providing a stabilizing effect by which the changing gear is held in an initial position with the toothless gap facing the driving gear, a solenoid coil wound on another portion of the yoke assembly and being operative, when energized, to generate a magnetic force by which the magnet and changing gear are angularly displaced from the initial position for engagement of the toothed periphery by the driving gear to cause turning of the changing gear, an operating member, such as a head base plate of the tape recorder, movable from an inactive position to an active position for establishing a respective mode of the tape recorder and being yieldably urged to return to its inactive position, an actuating assembly, desirably in the form of a cam rotatable with the changing gear and an actuating lever engageable with the cam and with the head base plate or other operating member, and being responsive to turning of the changing gear by the driving gear for moving the operating member to its active position, and an armature assembly moved from a free position spaced from the yoke assembly to a holding position against a portion of the latter in response to movement of the operating member to its active position, the yoke assembly and solenoid coil being operative, when the coil is energized, to magnetically hold the armature assembly in its holding position for preventing return of the operating member to its inactive position.

Abstract: MODE CHANGING APPARATUS A feather-touch mode changer having low power requirements and being capable of selectively providing a plurality of modes of operation of a tape recording/reproducing apparatus, has two changing mechanisms which are each of the type that includes a rotatable changing gear with a toothless gap, a selectively actuable trigger for causing initial angular displacement of the changing gear from an inactive position in which the toothless gap faces a drive gear to an actuating position in which the changing gear engages the drive gear, and an actuating lever that moves in a response to the rotation of the changing gear by the drive gear. The two changing mechanisms are selectively actuable, and a single drive gear is positioned for engagement with both changing gears. Each of the two changing mechanisms has associated with it a selectively energizable electromagnetic device and a locking lever that moves into a locking position in response to movement of the respective actuating lever. Each electromagnetic device is energized upon actuation of the respective trigger means to magnetically hold the respective locking lever in its locking position. The mode changing apparatus also includes mode establishing mechanisms comprising a plurality of cooperating gears and levers that are engaged by the actuating and locking levers upon selective operation of the changing mechanisms to establish FWD, FF, REW, PAUSE and ADS (Automatic Detection of Silence) modes of operation of the tape recording/reproducing apparatus.
