Definitions

  • the previous data carriers generally referred to as chip cards, with standardized dimensions generally contain semiconductor memory elements with a relatively small memory capacity and a logic circuit which is in the foreground.
  • semiconductor memory elements With the increasing availability of inexpensive semiconductor memories that have a storage capacity in the megabit range or far above, there is a desire to be able to access a large number of similar data carriers of the largest possible storage capacity quickly and easily.
  • These data carriers are to be made available, for example, for digitized music signals, software for data processing systems, etc.
  • the semiconductor memories can be writable and erasable memories or just read memories (ROM).
  • the data are preferably stored in compressed form with regard to their redundancy.
  • PCMCIA connector This connector is generally known under the abbreviation "PCMCIA connector" and currently contains 68 pin connections on the device side or 68 sockets on the card side.
  • the mechanical implementation usually takes place in such a way that one to three guide rails for different card thicknesses and also an ejection mechanism for the memory cards are provided in the PC housing.
  • a PCMCIA-compatible interface system for the usual memory cards is described, for example, in US Pat. No. 5,334,046.
  • the conventional data carrier arrangements in particular the memory cards, are only of limited suitability for storing larger amounts of data. If a processing device is to access several PCMCIA cards, either a card change must be carried out or, if several cards remain inserted at the same time, there must be a corresponding connection socket in the processing device for each card. These connection devices require a relatively large volume.
  • the object of the present invention is to create the conditions for the novel, stackable data Carriers, which themselves do not contain any pluggable contacts, can be connected to these processing devices via an interface which is already present on commercially available data processing devices, here the PCMCIA connecting bar.
  • FIG. 1 shows a perspective top view of an adapter according to the invention, Figure 2 in the same representation a known PCMCIA connection strip with pins.
  • the adapter 1 shows a cuboid adapter 1 with a receiving space 2 that is open toward the top.
  • the adapter 1 corresponds approximately to the usual credit card size, while its thickness, in accordance with the PCMCIA standard, can be 3, 6 or 12 mm. With a 12 mm adapter version in particular, you can therefore easily use both
  • Main surfaces of the adapter are each provided at least one receiving space 2 open to this main surface.
  • three data carriers 3 can be inserted next to one another in the receiving space 2.
  • the number of data carriers 3 that can be inserted into the adapter 1 essentially depends on their size. Since the memory chip itself only takes up an area of approximately 1 cm, data carrier sizes down to approximately 1/8 of the credit card format can be realized.
  • Troughs can also be incorporated in the data carriers 3, for example, which facilitate manual intervention from the outside and thus the removal of the data carrier 3 from the adapter 1.
  • FIG. 1 there are also indicated on the bottom surface of the receiving space 2 rows of counter-contact surfaces 6 arranged side by side for the contact surfaces 7 respectively arranged on surfaces of the data carrier 3.
  • the stackable data carriers 3 will typically only have 8 connections. If a plurality of recording spaces 2 or a plurality of spaces for data carriers 3 are provided in a recording space 2, then the associated mating contact surfaces 6 are connected to one another in the adapter, as indicated in FIG. 1.

  • the adapter 1 thus equipped with data carriers 3 can now be pushed into the corresponding PCMCIA slot of a processing device, which can be constructed, for example, as shown schematically in FIG. 2, it ultimately being used for the plug contact between the device-side connection strip and the connection - counterpart ⁇ of the adapter 1 comes.
  • one or more data carriers 3 can also be subsequently pushed into the adapter 1 located in the slot, provided that an opening is provided in the adapter 1 on the edge side. It is also readily possible to arrange at least two data carriers 3 stacked one above the other and serially connected by means of their contact surfaces 7 at a card slot in the receiving space 2.
  • the adapter concept according to the invention which initially only ensures an electromechanical adaptation to the PCMCIA configuration, can easily be expanded by means integrated in the adapter for the electronic adaptation of a data access which is organized in parallel on the terminal strip side and is serially organized on the data carrier side.
  • the electrical contacts of the terminal strip correspond, for example, on the PC side to the address and data lines of a microcomputer. If, for example, a special integrated circuit is arranged in the connection counterpart area 9 of the adapter 1 and the socket connections of the connection counterpart 8 are connected upstream, the data carriers 3 inserted into the adapter 1 can be considered as a memory expansion card on the system bus of the microcomputer.
  • a connector is arranged on an edge of the adapter opposite the connection counterpart 8, to which an external card stack can be connected by means of a connector.
  • This connector can be connected to a card stack arrangement, for example, by means of a cable.

Abstract

Ces nouveaux supports portatifs de données (3) ont à leur surface supérieure des surfaces de contact (7) non enfichables qui permettent d'établir un contact galvanique avec les supports de données adjacents (3) et en même temps avec un système de bus lorsque plusieurs supports de données (3) de même type sont empilés. L'invention concerne un adaptateur (1) de forme sensiblement carrée avec un raccord (8) standardisé de type PCMCIA enfichable dans la barrette de connexions de l'appareil et au moins un réceptacle (2) pour au moins un support de données empilable (3). Des surfaces complémentaires de contact (6) situées dans le réceptacle entrent en contact avec les surfaces de contact (7) d'un support de données (3) placé dans le réceptacle.
