Abstract

In a housing (20) taking the form of a microtelephone, a dial-speech circuit (4), a receiver (24), a transmitter (25), a control unit (5), and a key pad (22) are accommodated. The telephone set further includes a subscriber listing (1) divided into sections (11). In each section a bar code (13) corresponding to a speed-calling number (12) is printed, and space is left free for writing in the name of a telephone subscriber and high or her telephone number (14). Disposed at one corner of the housing is an optical transmitter-receiver (21) which, together with the housing, forms a hand-held bar-code reading wand. Connected to the control unit is a memory (3) having storage locations defined by the speed-calling numbers, at each of which locations a certain telephone number (32) is stored. By using the hand-held wand to read the speed-calling number storage code in the subscriber listing, the associated telephone number is automatically dialled by the control unit.

Claims

1. A telephone set of the type having a subscriber listing containing bar codes and associated subscribers'"'"' numbers, a bar-code reader, a data memory for storing and outputting dialling data read by the bar-code reader, a control unit, a key pad, and a dial-speech circuit for transmitting dialling data read out from the data memory over a subscriber line to the central office, wherein the improvement comprises:

said subscriber listing having a plurality of pages each divided into sections, each of said sections including sufficient space for entering at least the name of a subscriber, and

a bar code pre-printed in each of said sections and corresponding to a one- to three-digit speed-calling number,

said control unit being so programmed that each said speed-calling number read by said bar-code reader and converted into electrical signals serves to address other dialling data in said data memory, said control unit supplying said dialling data read out of the addressed memory location of said data memory to said dial-speech circuit.

2. The telephone set of claim 1, wherein said pre-printed speed-calling number bar code includes a standardized middle portion representing said speed-calling number and a non-standard prefix and/or suffix portion, said control unit utilizing said prefix and/or suffix portions for distinguishing the respective said speed-calling number from any standard bar-code entries containing a normally bar-code subscriber number.

3. The telephone set of claim 1, further comprising a nonfixed dialling-data carrier, wherein the numerals and command symbols (1 . . . 0, *, #, S) of said key pad are printed in bar-code form on said carrier.

4. The telephone set of claim 1, wherein said control unit further comprises a program memory and a microprocessor containing programs necessary for carrying out dialling with a subscriber number read out from said data memory and for storing subscriber numbers selected by the user at memory locations of said data memory determined by said pre-printed bar codes.

5. The telephone set of claim 4, wherein said pre-printed speed-calling number bar code includes a standardized middle portion representing said speed-calling number and a non-standard prefix and/or suffix portion, said control unit utilizing said prefix and/or suffix portions for distinguishing the respective said speed-calling number from any standard bar-code entries containing a normally bar-coded subscriber number.

6. The telephone set of claim 4 further comprising a nonfixed dialling-data carrier, wherein the numerals and command symbols (1 . . . 0, *, #, S) of said key pad are printed in bar-code form on said carrier.
