摘要:
For switching on an operating mode "playback, normal forward running", a recording and reproducing apparatus (1) for a drivable record carrier (3) has a playback servomechanism (29) which can be triggered by a playback button (23) and for switching on an operating mode "record, normal forward running" it has a record servomechanism (29') which can be triggered by a record button (24). Both servomechanisms (29, 29') have a driving component (39, 39'), a driven component (40, 40'), which can be brought into engagement with the driving part (39, 39'), for displacing at least one apparatus component (15, 16, 17, 18, 20, 22) and a blocking component (49, 49') which can be displaced by the relevant button (23, 24) from a blocking position into a release position. Between the record button (24) and the blocking component (49) of the playback servomechanism (29) there is provided a coupling arrangement (62) via which, upon actuation of the record button (24), the blocking component (49) of the playback servomechanism (29) can be displaced. As a result, when the record button (24) is actuated both the record servomechanism (29') and the playback servomechanism (29) are triggered (FIG. 4).

A magnetic-tape apparatus (1) comprises at least two buttons (9, 10, 11) for selecting modes of operation of the apparatus and at least one apparatus part (37) to be positioned in conformity with the modes selected by actuation of the button. For positioning the apparatus part (37) the apparatus comprises a servo mechanism (50) which can be driven by a motor (27), which mechanism comprises a first eccentric means (71) arranged on a servo wheel (52), a drive member (73) which is movable by this eccentric means (71), and an actuating member (85) which is movable by the drive member (73) for positioning the apparatus part (37). Depending on the selected mode of operation, the actuating member (85) can be set to different positions defined by stops (20, 21 23) associated with the buttons (9, 10, 11) by means of a control device (86) which comprises a second eccentric means (87) which can be driven by the motor (27) and at least one scanning element (89, 90, 91) for scanning the stops (20, 21, 23) associated with the buttons (9, 10, 11), which cooperates with the actuating member (85) and which moves this member to the various positions. The servo disc (52) comprises a disc-shaped axially projecting portion (58) on one of its radial surfaces, which portion carries a circumferential cam (87). The cam (87) constitutes the second eccentric means and in the disc-shaped portion (88) at the deck side a groove (71) is formed which constitutes the first eccentric means.

A magnetic tape apparatus (1) with a reversible magnetic head (28) has a rotatable head support (36), which can be turned between two operating positions and is rotatably mounted with play in a bearing opening (46) of a bearing device (45). The bearing device (45) is provided in the region of the bearing opening (46) with clearances (58, 59, 60, 61, 62) for the head support (36) and, in both its operating positions, the head support (36) is pressed exclusively against two predetermined bearing locations (96, 97 and 96, 98, respectively) in the bearing opening (46), these bearing locations (96, 97, 98) being of a punctiform design, seen in cross-section of the bearing opening (46).
摘要:
An apparatus has a part which can be moved to an operating position by an actuating device, in response to movement of a button to an on position. Upon movement of the part to its operating position, a latching member directly associated with the part latches the button in its on position. Upon sensing a predetermined condition in the apparatus, a control member prevents the transmission of the actuating movement by the actuating device to the part, and a user becomes aware that the part has not moved to its operating position because the button does not become latched in its on position.
摘要:
A capstan or pressure roller shaft is journalled in a single one-piece elongated bearing member having a bearing surface sufficient to define radial position and inclination of the shaft. The bearing member is aligned with respect to a mounting support on the tape recorder, to adjust shaft alignment, by two axially spaced cylindrical positioning surfaces which are received in axially spaced cylindrical receiving surfaces in the support. At least one of the positioning surfaces is eccentric with respect to the bearing member, and is fixed to the bearing member so that rotation of the bearing member about an axis defined by the receiving surfaces adjusts the inclination of the shaft. The shaft inclination may be adjusted by inserting a tool into the tape recorder, engaging a journal formed in a mounting support adjacent the bearing member, the tool having a gear which engages a toothed portion on the bearing member for rotating the bearing member about the support axis defined by the support receiving surfaces.

摘要:
A mechanism for performing a control function such as switching off an apparatus such as a tape recorder upon stopping of the rotary movement of a component at a time that other parts of the apparatus are still rotating. A pivotally mounted lever oscillates in response to rotation of the component, and stays at a central position upon stopping of the component. A coupling rod links the lever to a reciprocating connecting rod, and diverts the connecting rod from a path which will intercept the control function actuating device when the lever oscillates away from the central position.
