Patent number: 6567370Abstract: The invention relates to an apparatus for the recording or for the reproduction of information with a drive system for a scanning device for reading or writing information in one or more tracks of a recording medium. The object of the invention is to provide a drive system for a scanning device which requires little outlay and satisfies the requirements in respect of high positioning accuracy, short access time and self-locking. According to the invention, this object is achieved by means of a drive system comprising a toothed rack arrangement, a straight-toothed gearwheel and a worm, without a helically toothed worm wheel being necessary. For the purpose of an engagement in the straight-toothed gearwheel, the worm is arranged at an angle with respect to the axis of the gearwheel, which angle corresponds to the lead of the said worm.Type: GrantFiled: October 6, 2000Date of Patent: May 20, 2003Assignee: Thomson Licensing S.A.Inventor: Fritz Weisser

Patent number: 6024314Abstract: In recorders, in particular video recorders, the use of various sizes of cassette is intended and is already customary. For this purpose, the size of the cassette must be identified and the hubs of the transport drive changed appropriately. A mechanical coupling between the winding adjustment and the loading drawer during the loading operation, has no influence on the winding adjustment if a large cassette is inserted, whereas the identification and adjustment, formed by a lever, come into mechanical contact with the winding adjustment in the case of a small cassette. The mechanical coupling is formed by a U-shaped lever, the position.Type: GrantFiled: March 10, 1997Date of Patent: February 15, 2000Assignee: Deutsche Thomson-Brandt GmbHInventors: Bernadette Dannegger, Fritz Weisser

Patent number: 5999377Abstract: A head carrier plate is pressed in the direction of the longitudinal axis of the videotape by spring force against stops. The audio control head bears with its lower edge on a support which simultaneously serves as a tape guide of the lower edge of the videotape and as a pivotal support for the audio control head. Only two setting screws are then necessary, with which the head carrier plate can be set in terms of the angle of inclination with respect to the capstan shaft and in terms of the angle of inclination with respect to the longitudinal axis of the videotape.Type: GrantFiled: May 1, 1997Date of Patent: December 7, 1999Assignee: Deutsche Thomson Brandt GmbHInventors: Erhard Lauble, Klaus Oldermann, Fritz Weisser

Patent number: 5940359Abstract: Apparatus for interposing additional optical elements in the optical path of an optical read/write device includes said additional element mounted on a carrier pivotally mounted on a lens carrier which is subject to lateral translation. Stops on the carrier to which the additional element is mounted engage actuators arranged at the limits of lateral travel of the lens carrier, which limits are beyond the recordable areas of the recording medium. The engagement of the actuators with the carrier causes the carrier to pivot and either insert or remove the additional optical element in the optical path of the apparatus. Magnetic retainers are included to prevent the additional element from moving from the desired position.Type: GrantFiled: March 24, 1997Date of Patent: August 17, 1999Assignee: Deutsche Thomson-Brandt GmbHInventors: Heinz-Joerg Schroeder, Dietmar Uhde, Fritz Weisser

Patent number: 5764457Abstract: A cassette for use with a recording apparatus comprises: a housing for a recording medium, the housing having a first surface and side walls, the recording medium being accessible through one of the side walls; at least a part of a chip card affixed to the housing, forming a second surface of the housing and closing the cassette, the chip card part having a memory formed integrally therewith and externally accessible contacts; and, the contacts of the chip card being positioned on the second surface to be engageable by corresponding contacts in the recording apparatus when the cassette is inserted therein. One of the side walls has an access door for the recording medium and the second surface forms an upper wall of the housing as defined by the access door. The part of the chip card forming the second surface of the housing has a marking position at which light transmissivity can be controlled. The marking position can be rendered non transmissive to light to prevent recording.Type: GrantFiled: April 14, 1997Date of Patent: June 9, 1998Assignee: Deutsche Thomson-Brandt GmbHInventors: Dietmar Uhde, Jens Spille, Fritz Weisser, Hans-Joachim Platte, Jurgen Kaaden, Ernst F.

Patent number: 5758838Abstract: A toothed lever 11, 12 which engages in a toothed rim 21 of an intermediate wheel 5 when the tape drive changes over from the winding mode to the stop state, a pivot 18 for the intermediate wheel 5 is formed at the point of engagement, over which pivot the toothed rim 21 of the intermediate wheel 5 rolls and passes from the previously engaged supply spool 1 or take-up spool 2 into a disengaged position. It is then necessary only for the spools 1, 2 themselves to be braked.Type: GrantFiled: October 18, 1996Date of Patent: June 2, 1998Assignee: Deutsche Thomson Brandt GmbHInventor: Fritz Weisser

Patent number: 5663849Abstract: An actuating device for a pinch roller in a tape recording and/or playing device has a capstan spindle driven by a mechanism supported on a chassis. A pinch lever supports the pinch roller. At least one drive lever is rotatably coupled to the pinch lever and mounted to pivot about a fixed axis normal to the chassis for swiveling the pinch roller between resting and working positions. A spring connects the pinch lever and the at least one drive lever for urging the pinch roller against the capstan spindle only in the working position. A first guide controls the swiveling of the at least one drive lever. A lift roller is rotatably supported by the pinch lever and disposed in proximity to the pinch roller. The lift roller has a cylindrical region and a conical region having a diameter which increases in a direction away from the chassis.Type: GrantFiled: March 15, 1995Date of Patent: September 2, 1997Assignee: Deutsche Thomson-Brandt GmbHInventors: Fritz Weisser, Erhard Lauble
