摘要:
A tape transport device for moving the magnetic tape in both the directions of motion, particularly for micro-cassette decks, in which a tilting unit (62, 62') carries one of two gear wheels (74, 74'), meshing with a pinion (58) integral with the capstan (24) and the flywheel (56), to mesh also with the main wheel (118, 118') of the related friction unit, according to the rotational direction of the capstan, in order to carry out the winding of the tape, dragged by the capstan at the normal speed, onto the take-up reel. The tilting unit can comprise two plates (62, 62') separately movable in order to carry the related gear wheel (74, 74') to mesh, besides with the main wheel (118, 118'), also with an internal gear (60) provided at the flywheel (56), in order to carry out a fast search of tape passeges. In order to carry out fast searches in both the two directions without reversing the rotation direction of the motor, a satellite gear (94, 94') can be placed between the internal gear (60) and the gear wheel (74,74') only in one of the two rotation directions of the flywheel (56).

In the device for fastening a car radio (20) to the dashboard (12) of a vehicle provided with a space with a number of curbs (18) made between an insertion mouth and respective recesses (16), according to the present invention, one or more locking cam members (22,24) are moved from an inoperative position, which is inside the outline of the mouth of the dashboard, to a fastening position, in which each locking cam member (22,24) extends into a relating recess (16) and its cam engages and blocks the relating curb (18). In an embodiment form, a slide (26) provides for rotating two locking members (22,24), in the form of cam sectors, by means of a toothing. The slide (26) is in turn reciprocated by means of a threaded screw (46), accessible from the front panel (44) of the car radio (20).
摘要:
A device for the voice control, particularly of the functions of the tuning in search and audio regulations in an electromagnetic signal receiver allows the user to interfere through his voice only and without a physical contact with the apparatus, on the usual regulations of the apparatus itself. The device comprises a first microprocessor dedicated to the speech recognition and apt to receive the commands by the user through a microphone. The first microprocessor converts the analog signals received from the microphone into digital sampled signals and carries out the comparison between said samples obtained from the input and the samples which form the data table contained in its memory. Each time a command is recognized, on its output pins an electric control appears, which is utilized by a second microprocessor, dedicated to the control of the electromagnetic signal receiver, in order to provide the control effects desired by the user.

In a tape playback and, or recorder apparatus, of the type in which a first arm movable with respect to the frame carries at least a playback magnetic head, a second arm movable with respect to the frame carries a pressure roller and a fast movement lever is shifted in opposite directions starting from a rest position in which it sets the kinematic elements for the normal speed feeding towards one of the two positions in which it sets the kinematic elements forthe fast running of the tape in one of the two directions to cause the fast rewinding or winding of the tape, it is provided forthe use of a device for keeping operative and controllably disabling the fast running movement ofthe tape, for instance in orderto be ableto carry out, in combination with an electronic circuit not being a part of the present invention, the search of a particular prerecorded passage. The present device comprises means elastically fixable to the frame and releasable from it on a control coming from the cited electronic search circuit, for releasably keeping the fast movement lever in each of its two positions of fast running of the tape and arm lever means for causing the arms to move during the motion of the fast movement lever so as to take the pressure roller away from the capstan and carry the playback head away from the position of pressure contact with the tape.
