Definitions

  • the invention relates to a playback and / or recording device for disks, in particular CD disks, with a housing at least one disc holder for stacking at least one disc, at least one drive and one movable in the stacking direction of the disc magazine on at least one guide rod Computer-controlled transport device for the optional transport of the individual plate with the associated plate holder between any storage compartments and the drive.
  • Such playback and / or recording devices are used in particular in consumer electronics or increasingly also in electronic data processing as data archiving systems with mass storage devices, in which extremely high amounts of information and data are stored on the disks.
  • Large amounts of data and information are stored on disk-shaped, so-called compact discs, and a large number of such disks are stored in a disk magazine, since entire libraries are stored on the disk storage media can.
  • Such plate magazines have a plurality of receiving compartments arranged one above the other, in each of which a plate holder receiving a plate is arranged.
  • a desired plate with a plate holder is retrieved from the plate magazine and transported to a drive for writing or reading information and data on or from the plate by means of a computer-controlled transport device.
  • the transport device then transports the plate with the plate holder back into the corresponding receiving compartment of the plate magazine.
  • Such devices often also have a plurality of, mostly also interchangeable, plate magazines, so that the transport device also transports the plates back and forth between several plate magazines.
  • a disk player is known, with two opposing disk magazines in a housing, which contain disk holders with disks in stacked compartments.
  • a movable transport device is arranged in the housing in order to transport a desired disc with the associated disc holder back and forth between the receiving compartment in the disc magazine and a playback unit.
  • the transport device has a support arm for receiving a plate holder with plate.
  • the support arm is slidably supported on two vertically spaced guide rods via a holder.
  • the Transport device can be moved up and down with the support arm.
  • the two guide rods penetrate the holder of the transport device in the vicinity of the end faces thereof.
  • WO 90/04845 shows a disk player which is constructed similarly to the disk player according to WO 93/11535.
  • two guide rods running parallel to each other and vertically are provided, on which the transport device is slidably mounted.
  • One of the guide rods is guided laterally and the other guide rod in the middle through the transport device.
  • an archive unit for optical storage disks is known from DE 43 13 373 AI, in which the transport device for the disks can be moved up and down on two guide rods spaced apart and fastened in the housing. Two sleeves are arranged opposite each other on the carriage of the transport device, through which the guide rods are guided.
  • the transport device is moved on two spaced-apart guide rods arranged on the housing side. Due to the generally desired provision of an ever larger storage capacity, it is necessary to provide correspondingly large data archives, ie the devices for this are becoming larger.
  • a data archive can have a cabinet size or even consist of several cabinet-sized sub-archives. This in turn requires correspondingly long guide rods for receiving the transport device for the plates. It has been found that with increasing Length of the guide rods the plate with plate holder cannot be transported and stored exactly. This results from the fact that the long guide rods are exposed to larger oscillations or vibrations and consequently their distance changes more or less.
  • the object is achieved in that the transport device is guided in addition to the at least one guide rod on two spaced apart rails.
  • the transport device is then guided on at least one guide rod and on two spaced-apart running rails.
  • a three-point leadership is created.
  • two guide rods spaced apart from one another and, in addition, two guide rails spaced apart from one another can also be provided, as a result of which a quasi four-point guide results.
  • This multiple guidance results in an exact guidance of the transport device during its movement between its two extreme movement points.
  • This leads to a positionally accurate conveyance and storage of the disk with the disk holder in the disk magazine and the drive, in particular with a relatively high-profile housing of the playback and / or recording device.
  • the two running rails are fastened parallel to one another in the housing.
  • the two rails can be attached to the top of the housing and to the housing base, so that the entire height of the device can be used for the transport route of the transport device.
  • the transport device expediently has a support arm for receiving the plate holder and a carriage which can be moved on the at least one guide rod and is guided in the two spaced-apart running rails.
  • the running rails are designed as U-shaped rails, into which pins arranged on the carriage of the transport device engage.
  • the pins can, for example, be fastened to the slide by screwing or riveting and, due to the relatively small contact surface, ensure low friction during the movement of the slide.
  • the pins are preferably resiliently attached to the carriage of the transport device. This allows the pins on the carriage of the transport device to be guided in the U-shaped rails with almost no play.
  • the pins are expediently formed on the carriage of the transport device. This avoids additional manufacturing processes for fastening the pins.
  • the pins on the carriage of the transport device preferably consist of an elastic material.
  • the sledge and the pins can be molded from a plastic in a two-component injection molding process.
  • each pin is surrounded by an elastic sleeve guided in the running rail.
  • the elastic sleeve serves to compensate for manufacturing-related tolerances, which can cause the transport device to jam during its movement sequences. Furthermore, the sleeve dampens vibrations of the plate changer, so that they are not transmitted to the transport device.
  • each pin carries an elastic disk on which the sleeve guided in the running rail is supported.
  • the disk preferably has greater elasticity than the sleeve.
  • each of the running rails has an insert with a longitudinal groove for receiving the associated pin on the carriage of the transport device.
  • the pin slides in the longitudinal groove of the running rail insert.
  • FIG. 3 is an enlarged view of a partial side view in the direction of arrow III of FIG. 1,
  • FIG. 4 is a sectional bottom view of the device of FIG. 1,
  • Fig. 5 is an enlarged view of the detail V of FIG. 4 and
  • FIG. 6 is an enlarged view of the detail VI of FIG .. 5
  • the housing 1 of a playback and / or recording device for disks is shown, the illustration of the disk magazines, disk holders with disks and drives being dispensed with. These components are usually included in the housing 1.
  • a transport device 2 which serves to transport a plate with a plate holder back and forth between one or more plate magazines and one or more drives.
  • the transport device 2 consists essentially of a support arm 3 which holds the plate holder with the record plate. Furthermore, the transport device 2 comprises a carriage 4 which is formed in one piece with the support arm 3 and which is penetrated by two guide rods 5. These guide rods 5 are spaced apart in parallel in such a way that they each protrude through the laterally outer region of the carriage 4 of the transport device 2.
  • the two guide rods 5 are fastened on the one hand according to FIG. 1 on the housing base 6 and on the other hand according to FIG. 4 on the upper side 7 of the housing and protrude through guide bushes 12 which are inserted in the carriage 4.
  • the guide bushes 12 take up the guide rods 5 with little play.
  • the transport device 2 is moved vertically along the guide rods 5, so that a plate holder with the plate accommodated therein can be conveyed out of a receiving compartment of a plate magazine to a drive and back again.
  • a pin 8 is arranged on the outer end faces of the carriage 4 of the transport device 2.
  • the pin 8 carries an elastic washer 9 and an elastic sleeve 10, the washer 9 having greater elasticity than the sleeve 10.
  • a U-profile-shaped running rail 11 is fastened to the housing 1.
  • Each of these running ⁇ rails 11 runs spaced and axially parallel to the guide rails 5. Between the legs of the running rail 11, the sleeve 11 arranged on the pin 8 is guided with play.
