摘要:
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.

In order that natural oscillations on a pickup of a recording or playback machine for optical recording carriers are avoided to the greatest extent, or at least shifted into uncritical frequency ranges, a toothed rack which is stiffened, preferably with a rib, and lies by means of drivers against drivers of the pickup is used instead of a flexible toothed rack. All the drivers have guiding bores, through which a guiding rod is passed. Provided between a driver of the toothed rack and a driver of the pickup is a compression and torsion spring, which is configured as a wire spring and both compensates for the axial play between the toothed rack and the pickup and presses the toothed rack against a gearwheel driving it.

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.

The invention relates to a medical cutting and/or holding instrument having a shaft, a tool mounted on the distal end of the shaft and consisting of two jaw members, and also having a handle that is mounted on the proximal end of the shaft, consists of two gripping members, and serves to open and close the jaw members of the tool. In order to produce a simply constructed and easily cleanable medical cutting and/or holding instrument, it is proposed according to the invention that the shaft should consist of two shaft rods, each configured without joints as a single construction with one gripping member of the handle.

The invention relates to a medical cutting and/or holding instrument having a shaft, a handle consisting of two gripping members on the proximal end of the shaft, and a push-pull rod for activating a tool that is positioned on the distal end of the shaft and consists of two jaw members, such that the push-pull rod can be coupled with at least one rotatable jaw member of the tool on the distal end and with one movable gripping member of the handle on the proximal end. To produce a medical cutting and/or holding instrument that is of simple construction and allows simple and versatile handling, it is proposed with the invention that the push-pull rod is configured as a component that is independent of the shaft and mounted outside the shaft, entirely on the rotatable jaw member of the tool and on the movable gripping member of the handle.

A device for the transport of recording media (3) of varying or different widths and/or thicknesses while automatically aligning the same includes a rotatably mounted and driven friction roll (1) and a plurality of rotatable pressure rollers 2a, 2b, 2c arranged in abutment with the friction roll periphery. A guide surface (6) for one of the lateral edges (3a) of the recording medium, which surface extends perpendicular to the friction roll axis (5), is associated with one end (4) of the friction roll. The pressure rollers (2a, 2b, 2c) are located off-center with respect to the length (7) of the elongated friction roll on the side or section thereof closest to the guide surface (6), while the longitudinal section (8) of the friction roll (1) which is most remote from the guide surface (6) is free of pressure rollers. The spacing (10) between the guide surface (6) and that one of the pressure rollers (2c) located most remote from the guide surface is selected so as to be at no more than one-half of the minimum of recording media that are intended for use with the transport device.
摘要:
An optical scanning apparatus for various appliances for recording or reproducing data or information using an optical recording medium has an interchangeable driving segment for matching the optical scanning apparatus to various driving systems in various appliances for recording or reproducing data or information. The driving segment, which is a one-piece toothed rack, for example, has an asymmetrical screw head depression in a hole for receiving a countersunk-head screw which connects the driving segment to the optical scanning apparatus at a contact face provided as a reference face for the purpose of arranging the driving segment parallel to a guide bar on the optical scanning apparatus. The contact face is arranged so as to deviate from a vertical line relative to the axis of the countersunk-head screw, and a force which emanates from the asymmetrical screw C head depression and which is generated when the countersunk-head screw is screwed in ensures that the driving segment is arranged parallel to the guide bar on the optical scanning apparatus.

The invention relates to a medical cutting and/or holding instrument having a shaft, a handle consisting of two gripping members that is positioned on the proximal end of the shaft, and a push-pull rod mounted in a guide groove of the shaft to actuate a tool consisting of two jaw members that is positioned on the distal end of the shaft, such that for opening and closing the tool the push-pull rod can be coupled on the distal end with at least one rotatable jaw member of the tool and on the proximal end with a rotatable gripping member of the handle, and such that the push-pull rod and the rotatable gripping member can be dissolubly connected with one another by a coupling mechanism. To produce a medical cutting and/or holding instrument that can also be used for endoscopic purposes, it is proposed with the invention that the push-pull rod is coupled with the rotatable components both on the proximal and the distal ends with free play in a direction essentially perpendicular to the direction of motion of the push-pull rod.
