Claim 3

An electronic scale according to claim 1, wherein said key input unit includes a plurality of keys and replaceable sheets indicating article names and other items associated respectively with the positions of the keys.

Claim 4

An electronic scale according to claim 1, wherein said key input unit includes a plurality of keys, each key generating a signal, and wherein said key input unit includes means for switching the keys between a first mode for generating signals corresponding to numerals and a second mode for generating signals corresponding to numerical/characters.

Claim 5

An electronic scale according to claim 1, wherein said key input unit includes means for generating words, phases and other items.

Claim 6

An electronic scale according to claim 1, wherein each item of data entered in the storage unit has a call number associated therewith and wherein said printer includes means for printing items of data stored in said storage unit in the order of call numbers thereof.

Claim 7

An electronic scale, comprising: a weighing unit for weighing an article and generating a weight signal corresponding to the weight of the article; a key input unit for generating a character code signal corresponding to the article, including an article name signal represented by one character corresponding to the article, for generating a recall signal corresponding to each character code signal, and for respectively selecting and specifying the size of characters to be printed in accordance with the name, weight and price of the article, the size being different for each of the name, weight and price; an arithmetic control unit, operatively connected to said weighing unit and said key input unit, for computing the price of the article based on the weight signal and the character code signal, and for generating a price signal corresponding to the computed price; a memory for storing characters corresponding to keys included in said key input unit; storage means for storing the specified size of the characters; conversion means for converting characters stored in said memory to character codes of the specified character size; a storage unit, operatively connected to the arithmetic control unit, for storing article data in accordance with the character code signal; a display unit, operatively connected to the arithmetic control unit, for displaying characters corresponding to the weight and price of the weighed article in accordance with the weight and price signals using the character codes, said disply unit including means for counting and displaying the number of entered characters while an article name signal is being generated by said key input unit; and a printer, operatively connected to the arithmetic control unit, for printing characters of the specified size corresponding to the weight, price and name of the weighed article in accordance with the weight, price and article name signals using the character codes.

Claim 8

An electronic scale, comprising: a weighing unit for weighing an article and generating a weight signal corresponding to the weight of the article; a key input unit for generating a character code signal corresponding to the article, including an article name signal represented by one character corresponding to the article, for generating a recall signal corresponding to each character code signal, and for respectively selecting and specifying the size of characters to be printed in accordance with the name, weight and price of the article, the size being different for each of the name, weight and price; an arithmetic control unit, operatively connected to said weighing unit and said key input unit, for computing the price of the article based on the weight signal and the character code signal, and for generating a price signal corresponding to the computed price; a memory for storing characters corresponding to keys included in said key input unit; storage means for storing the specified size of the characters; conversion means for converting characters stored in said memory to character codes of the specified character size; a storage unit, operatively connected to the arithmetic control unit, for storing article data in accordance with the character code signal; a display unit, operatively connected to the arithmetic control unit, for displaying characters corresponding to the weight and price of the weighed article in accordance with the weight and price signals using the character codes, said disply unit including means for counting and displaying the number of entered characters while an article name signal is being generated by said key input unit; and a printer, operatively connected to the arithmetic control unit, for printing characters of the specified size corresponding to the weight, price and name of the weighed article in accordance with the weight, price and article name signals using the character codes.
