Definitions

  • the invention relates to a playback / recording and / or output device for information carriers, in particular for compact disk change devices with an essentially several drives and magazines for the housing containing the information carriers, which can be closed by at least one door , and with a computer unit in which the device program is stored.
  • DE-Al-41 40 451 discloses a gaming machine with a door which can be closed by at least one lock, an alarm system, a microprocessor, at least one memory and an input / output unit which is used as a device for recording and evaluating an identification device Evidence of access authorization to the inside of the gaming machine is formed.
  • the housing of the gaming machine has an additional opening, through which the identification device for proving the access authorization can be inserted from the outside when the device is closed.
  • the Identification device is a chip card containing a readable and writable memory. Only after successful verification of the access authorization, which is carried out by reading out the identification code stored on the chip card, is the lock released via additional relays or an electromagnetic lock on the appliance door. The additional relays, which are connected to the door lock, cause the lock pawl to move by switching the electromagnet and thereby actuating a bolt of the lock.
  • Such a device contains a complex input / output unit in connection with the identification device, which is not suitable for electronic entertainment devices which are intended for domestic use.
  • an emergency opening for example in the event of a power failure, is not provided.
  • Electromagnets in connection with a lever system are also known in a complex construction from EP-Bl-0197 025 as an emergency actuation device for handle-free door locks on motor vehicles.
  • Bowden cables, for example, are used as unlocking elements. Applying such a solution is only possible with facilities that have a correspondingly large amount of space.
  • Devices of the type mentioned in the introduction generally have a folding door which can be folded down or at least one door which can be pivoted to the side.
  • a lock which can be actuated by means of a key is largely attached to the front and a push button is provided which is used to open the flap door or swing door.
  • a lock attached to the housing is operatively connected to a lever which is rigidly attached to a connecting rod arranged along a link side of the at least one door and mounted at its ends in the housing; the connecting link is rotatably connected to at least one locking link which is in locking engagement with the door; and the door can be unlocked by means of the locking linkage by electromagnetic or manual action when the device program has conveyed all the information carriers back from the drives into the magazines.
  • This measure realizes a security system in the device, which initially only allows authorized persons access to the device or to the interior of the housing if they have a corresponding key that matches the lock. Only then will they be able to access the magazines in the device that contain the information carriers in order to remove them, to equip them with new information carriers and / or to replace them. Access should, however, also be prevented for the authorized persons if at least one of the magazines has not yet is completed because one or more information carriers may still be located in one or more drives. Only the turning operation of the key in the lock and the subsequent actuation of the OPEN DOOR key instruct the device program stored in the computer unit to use the transport devices in the device to bring out the information carriers located in the drives and return them to the associated magazines ⁇ to be ordered. This prevents that, despite the change of the magazines, the information carriers assigned to them are still in the drives of the device, which can ultimately lead to operational malfunctions.
  • the locking linkage has a pawl which engages in a recess arranged on the side of the door opposite the articulation side. This effects the actual door locking and locking and forms the actual locking and unlocking element.
  • the pawl can be actuated by an electromagnet arranged in the interior of the housing, the plunger of which engages the pawl in a reciprocating manner in order to enable the device door to be unlocked or locked.
  • the pawl In order to be able to follow the back and forth movement of the plunger of the electromagnet, the pawl is designed to be spring-loaded against the electromagnet, so that the pawl always strives to lie against the plunger of the electromagnet.
  • a first switching element connected to the computer unit controlling the device program is provided, which can be actuated by the bolt of the lock attached to the housing in order to switch the electromagnet acting on the pawl.

  • This tool can be an awl, a screwdriver or some other sharp object.
  • this can be pushed away by exerting lateral pressure against the spring resistance of the pawl, so that the pawl disengages from the recess in the door, the door being locked. is opened and thus access to the interior of the housing is free, and the magazines can be removed.
  • this also requires at least actuation of the lock beforehand, since only the bolt of the lock opens the opening for inserting the wire-like tool. In this case, pressing the OPEN-DOOR button has no effect due to a power failure.
  • a push button which is spring-loaded in the opening direction of the door and supports the door opening is provided in the interior of the housing. This automatically pushes the door open when the recess belonging to the door is released by the pawl of the locking linkage.
