Abstract

An apparatus for storing and releasing information contains at least one reading device for reading codings arranged upon, or associated with, saleable goods. Also provided is a storage unit for storing information and a corresponding output unit. The apparatus offers to users, in department stores or the like and directly and reliably, specific information concerning products to be sold. The data processing unit comprises a programmable coding unit by means of which, on the one hand, address signals for the information and, on the other hand, associated codings are stored. By use of a reading device, and through the coding unit, the desired information is called upon from the storage unit and is made accessible on the output unit.

Claims

1. An apparatus for storing and retrieving information associated with various coded items, said apparatus comprising:

(a) a reading device for reading codings associated with individual items to produce coding signals;

(b) a storage unit for storing information associated with individual items at respective storage addresses each accessible through a corresponding address signal;

(c) a data processing unit for receiving coding signals read by said reading device and transmitting address signals to said storage unit to retrieve stored information from the corresponding storage addresses, wherein at least one address signal has more than one coding signal at one time associated therewith, and wherein said data processing unit comprises a coding unit which in response to receipt of at least one coding signal produces an associated address signal for transmission to said storage unit, and said coding unit is selectively reprogrammable to change at least one coding signal associated with the address signal corresponding to any desired storage address of said storage unit while maintaining the address signal unchanged; and

(d) an output unit for making retrieved information avaiable to a user of the apparatus.

2. An apparatus according to claim 1, wherein said reading device includes control means for retrieving additional information from said storage unit.

3. An apparatus according to claim 1, wherein to establish or change an association between a given item and selected stored information, a new coding signal corresponding to a code associated with said given item is stored in the coding unit in association with a previously sotred address signal corresponding to the storage address of said selected information.

4. An apparatus according to claim 1, wherein a control unit is provided to associate a coding signal corresponding to a coding read by said reading device with an address signal selected by said control unit, and to cause the associated coding signal and address signal to be subsequently stored together in said coding unit.

5. An apparatus according to claim 1, further comprising a second reading device and a control unit operatively connected to said coding unit for associating a coding signal corresponding to a coding associated with a given item with an address signal corresponding to the storage address of selected stored information.

6. An apparatus according to claim 1, wherein said coding unit comprises at least one programmable converter including means for detecting a coding signal corresponding to a coding associated with at least one item and for converting the detected coding signal into an associated address signal corresponding to the storage address of information in said storage unit.

7. An apparatus for storing and retrieving information associated with various coded items, said apparatus comprising:

(a) a reading device for reading coding associated with individual items to produce coding signals;

(b) a storage unit for storing information associated with individual items at respective storage addresses each accessible through a corresponding address signal, wherein the information stored at each storage address in said storage unit is fixed and unchangeable;

(c) a data processing unit for receiving coding signals read by said reading device and transmitting address signals to said storage unit to retrieve stored information from the corresponding sotrage addresses, wherein said data processIng unit comprises a coding unit which in response to receipt of at least one coding signal produces an associated address signal for transmission to said storage unit, and said coding unit is selectively reprogrammable to change at least one coding signal associated with the address signal corresponding to any desired storage address of said storage unit while maintaining the address signal unchanged; and

(d) an output unit for making retrieval information avaialbe to a user of the apparatus.

8. An apparatus according to claim 7, further comprising a supplemental storage unit containing additional or altered information which can be retrieved for transmission to said output unit.

9. An apparatus according to claim 8, wherein said information contained in said supplemental storage unit comprises audio information which, when retrieved, is transmitted to a loudspeaker in said output unit.

10. An apparatus according to claim 9, wherein said information is transmitted through a mixer stage to said output unit.

11. An apparatus according to claim 8, wherein said supplemental storage unit constitutes an intermediate memory for holding information from a main storage unit during presentation of a sequence of pictures through said output unit and releasing the held information to the output unit when a still picture is shown.

12. An apparatus according to claim 11, comprising means for storing information to be held in said intermediate memory on a sound track in parallel with the pictures of a picture sequence in said main storage unit.

13. An apparatus according to claim 11, comprising means for storing information to be held in said intermediate memory in individual parts between the pictures or half pictures of a picture sequence in said main storage unit.
