A scanning device for an apparatus for reading from or writing to optical recording media, with at least one mounting device with a receptacle along an optical axis for an optical component arranged on a cylindrical holder and with setting elements for the holder along the axis or along and about the axis is disclosed. The scanning device of this type reduces the number of setting elements for adjusting an optical component and the setting elements are formed and arranged in a space-saving manner which considerably simplifies the adjusting operation.

Scanning device for an apparatus for reading from or writing to optical recording media

According to the invention, parts of the setting mechanism are integrated into the housing and/or setting mechanisms are arranged in such a way that they assume not only the setting function of one axis but also the guiding function of a further axis. The setting mechanisms are formed by eccentric bolts. Guiding pins serve for guidance in one axis. Clamping screws serve for fixing the adjusted axes. Slots serve as guiding aids in the various axes.

Arrangement for setting an image display device with a housing

The invention concerns a device which comprises a device for displacing to transversely position a multitrack tape in front of a reading and/or writing head. The magnetic tape carries a plurality of elementary tracks which are grouped in several bundles. These bundles are selectively accessed using the device for displacing. The writing and/or reading head can write and/or read information from elementary tracks contained in one bundle at a time. The device for displacing comprise a tape guide acting on longitudinal edges of the tape and transversely translating the tape. Furthermore they comprise either a movable tape reels platform or movable pins to accommodate for the transverse tape displacement.

A drive mechanism for driving independently a first and a second coaxial reel, uses only a single rotatable driving unit for driving both coaxial reels. Independent drive is achieved by reversing the rotation of the driving unit.
