US4430713A — PLU-Code controlled electronic cash register

Claim 1

Independent Claim 173 words

In an electronic cash register employing a PLU (price-look-up) function, wherein merchandise information such as unit cost, taxation information and classification information is preset by an operator, a PLU code information preset system comprising: first means for automatically developing PLU code signals in a progressive order; a synthetic speech generation system for audibly instructing an operator of a necessary key operation for presetting the PLU code information associated with each PLU code signal; a digital display unit for displaying the presently introduced PLU code information; memory means for storing the introduced preset PLU code information; addressing means for introducing the preset PLU code information into a predetermined memory section of the memory means; a check request key; and read-out means for reading out the PLU code information stored in said memory means in a progressive order in response to actuation of said check request key; said synthetic speech generation system further including means for sequentially providing a synthetic speech sound in accordance with said PLU code information read out by said read-out means.

Claim 2

Dependent Claim 173 words

In an electronic cash register employing a PLU (price-look-up) function, wherein merchandise information such as unit cost, taxation information and classification information is preset by an operator, a PLU code information preset system comprising: first means for automatically developing PLU code signals in a progressive order; a synthetic speech generation system for audibly instructing an operator of a necessary key operation for presetting the PLU code information associated with each PLU code signal; a digital display unit for displaying the presently introduced PLU code information; memory means for storing the introduced preset PLU code information; addressing means for introducing the preset PLU code information into a predetermined memory section of the memory means; a check request key; and read-out means for reading out the PLU code information stored in said memory means in a progressive order in response to actuation of said check request key; said synthetic speech generation system further including means for sequentially providing a synthetic speech sound in accordance with said PLU code information read out by said read-out means.

Claim 3

Dependent Claim 72 words

The electronic cash register of claim 1, wherein said synthetic speech generation system further includes: second means for audibly announcing a PLU code number in response to the PLU code signal derived from said first means; third means for developing a synthetic speech sound for instructing the operator to introduce the unit cost information; and fourth means for developing a synthetic speech sound for instructing the operator to introduce the classification information.

Claim 4

Independent Claim 157 words

A system for loading commodities information into a memory of an electronic cash register, said system comprising: means for sequentially producing code signals and for providing each of these signals to an operator, each of said code signals being representative of an item of merchandise; and input means for entering data representative of commodities information into the memory, said commodities information being identified in the memory by its associated code signal received from said means for sequentially producing and providing and being representative of the item of merchandise and its associated commodities information; said means for sequentially producing and providing including: means for incrementing a current code signal after the completion of entry of the data corresponding to this current code signal by said input means to produce a new code signal; and a synthetic speech generator responsive to said means for sequentially producing code signals, said synthetic speech generator audibly announcing each code signal when produced.

Claim 5

Independent Claim 157 words

A system for loading commodities information into a memory of an electronic cash register, said system comprising: means for sequentially producing code signals and for providing each of these signals to an operator, each of said code signals being representative of an item of merchandise; and input means for entering data representative of commodities information into the memory, said commodities information being identified in the memory by its associated code signal received from said means for sequentially producing and providing and being representative of the item of merchandise and its associated commodities information; said means for sequentially producing and providing including: means for incrementing a current code signal after the completion of entry of the data corresponding to this current code signal by said input means to produce a new code signal; and a synthetic speech generator responsive to said means for sequentially producing code signals, said synthetic speech generator audibly announcing each code signal when produced.

Claim 6

Dependent Claim 53 words

The system of claim 3 wherein said synthetic speech generator comprises: means for converting said code signals into digital representations of their audible form; analog converter means for converting said digital representations into an analog signal; and speaker means for converting said analog signal into said audible annunciation of the corresponding code signal.

Claim 7

Dependent Claim 29 words

The system of claim 3 wherein said synthetic speech generator further comprises means for audibly instructing the user to introduce the data representative of commodities information into the memory.

Claim 8

Dependent Claim 47 words

The system of claim 3, wherein said means for sequentially producing and providing includes a display for allowing the operator to view both code signals produced by said means for sequentially producing and providing and said data representative of said commodities information entered by said input means.

Claim 9

Independent Claim 15 words

The system of claims 3 or 5, wherein said commodities information includes unit cost information.

Claim 10

Independent Claim 14 words

The system of claims 3 or 5, wherein said commodities information includes classification information.

Claim 11

Independent Claim 14 words

The system of claims 3 or 5, wherein said commodities information includes tax information.
