A electromagnetic camshaft adjuster comprising: an armature unit which can be moved relative to a pole core when a stationary coil unit is energized and which has an armature plunger; and a permanent magnet unit by means of which the armature unit is held in a rest position when the coil unit is not energized; and a spring element between the pole core and the armature unit to force the armature unit axially away from the pole core, the spring force of the spring element being chosen smaller than the holding force of the permanent magnet unit when the coil unit is not energized. The permanent magnet unit is stationarily arranged between a housing cover and the pole core, the armature plunger is rotationally arranged, and the spring element is supported on a part of the armature unit which is rotationally fixedly mounted.

An electromagnetic adjusting device having a first, second and third plug contacts for operating the adjusting device on an operating voltage source having a first and second voltage pole. The device can include an actuator coupled to the plug contacts. The actuator can have a magnet coil with a first terminal connected to the first plug contact, a second terminal connected to the second plug contact, where either the first or the second plug contact is connected to the first voltage pole. The magnet coil can also have a first transistor with a first control electrode connecting the first terminal to the third plug contact, a second transistor having a second control electrode connecting the second terminal to the third plug contact, a first resistor connecting the first control electrode to the second plug contact and a second resistor connecting the second control electrode to the first plug contact.

Electromagnetic adjusting device

An electromagnetic actuating apparatus with a first armature arrangement axially displaced between a rest and actuating position and connected to a first actuating element. A pole core is brought into magnetic operative connection with the first armature arrangement. An axially oriented coil unit is energized, influencing the magnetic connection between the first pole core and the first armature arrangement, and a second armature arrangement is connected to a second actuating element and axially displaced between a rest and actuating position. A second pole core can be brought into magnetic operative connection with second armature arrangement, its pole core oriented axially to first pole core influencing its magnetic operative connection with second armature arrangement. A permanent magnet unit, the magnet axis is oriented radially and stationary, generates magnetic operative connection both between the first pole core and first armature arrangement and between the second pole core and second armature arrangement.

The invention relates to a scanning device for optical discs, having an adjustable scanning unit tensioned against a carrier with a spring. For minimizing the structural space for the spring and avoiding separate fixing elements, the spring is formed as a dip spring, having an elongated spring limb and a bearing limb formed transversely with respect to the latter, which clip spring impinges at one of its ends with the bearing limb on the carrier with a contact force and is supported at its other end at a distance from the impingement location on the housing.

Scanning device for optical discs

A device for reading from or writing to optical recording media, having an optical scanner for generating a scanning beam and for detecting a detection beam influenced by the optical recording medium, and a lens holder for focusing the scanning beam onto the optical recording medium; the lens holder being mechanically and electrically coupled to the scanner by retaining wires is disclosed. In a device according to the invention at least one of the retaining wires is a multistrand wire.

The present invention relates to a device for reading from and/or writing to optical recording media, having a light source for producing a scanning beam for scanning the optical recording medium, detection means for detecting the beam influenced by the optical recording medium, and an optical element arranged in the optical beam path by means of a holder. The optical element has in a plane perpendicular to the axis of the beam path outer boundary lines inclined to one another in such a way as to enable a unique orientation. The holder has a cutout with correspondingly inclined inner boundary lines.

Device for reading from and/or writing to optical recording media

The invention relates to a recording and/or reproduction apparatus for optical recording media with means for parallel orientation of the scanning device with respect to the surface of the recording medium, the scanning device being arranged on a slide that is guided on a guide rod. A tensioning element is provided, by means of which the guide rod of the scanning device is fixed on a baseplate in order to avoid a force transmission leading to the bending of the guide rod, said force transmission disadvantageously issuing from fixing or adjusting means of the guide rod, in an adjustable manner in a plane corresponding to the cross section of the guide rod. The fixing and adjusting device formed by means of the tensioning element has a small number of individual parts, the guide rod can be mounted on a shaped portion of the baseplate with a low outlay and nevertheless avoids to the greatest possible extent a force transmission to the guide rod that disadvantageously issues from fixing or adjusting means. The fixing an adjusting device is provided in particular for parallel orientation of the scanning device in a recording or reproduction apparatus for optical recording media with respect to the surface of the recording medium.

A disk player, e.g. for a CD or DVD, generally includes a tray receiving the disk to be scanned and a so-called cam slider moved between an IN-position for purpose of scanning and an OUT-position for purpose of loading the disk. Therein the movements and the end positions of the tray and the cam slider have to be monitored for proper operation. To do this generally several switches or a special complicated switch are needed. It is an object to simplify the means for performing said monitoring operations for movements in different directions and especially to achieve this by means of a single simple switch, only. The cam slider is provided with a chamfer for moving a switch lever of the switch into a first position (a) and further is provided with a control lever including a switch actuating area for moving said switch lever into a second position (b) said control lever being pivotally mounted on the cam slider against the action of a spring. By this solution it is achieved that movements in different directions can be monitored by a single simple switch only.
