Portable food-constituent-amount display and calculating system, and device to operate the system
First Claim
1. A portable food constituent amount display calculator which, when commanded, compares the total amount of at least one constituent of foods taken in per day with the necessary amount of each said constituent a day and displays the amount of each excess or deficiency for health control, comprisingan input section provided with a character-input keyboard for inputing names of food taken in by a user during the day, and for selectively indicating a plural number of a standard amount of said at least one constituent thereof;
- A food-data memory in which said food names and each said standard amount of each said constituent thereof are prestored;
means by which to read out from said food-data memory said standard amount of each said constituent of a food name which is input from the keyboard;
a display which shows an input food name and each said standard amount of each said constituent read out from the food-data memory and results of comparison and arithmetic operations;
an arithmetic and control section which performs said arithmetic operations, including adding the respective amounts of each said constituent of said foods taken in the day to form at least one respective total for the day for each said constituent;
an all-input food data memory which stores said food names and amounts of said constituents which are displayed and each said total from said arithmetic operations;
a necessary-constituent-amount memory which stores the necessary amount of each said constituent of each said stored food name; and
comparison means for comparing the respective necessary amount of each said constituent and the respective total from said arithmetic operations stored in said all-input data memory.

Abstract
A portable system gives information on the amounts of constituents of foods for health control. The system tells the amounts of nutritive constituents of foods and the total amount of nutritive constituents of foods taken a day by arithmetic operations, and determines excessive or insufficient amounts of constituents by comparison between the total amount taken a day and the necessary amounts. A small, portable calculator is provided with an input section having a keyboard for giving necessary commands with alphabetic characters A to Z, the numerals 0 to 9, =, -, ×, ÷, etc. to enter food items and the amounts of nutritive constituents. The portable calculator calculates the amounts of nutritive constituents of meals of the day, breakfast, lunch, supper and snack separately or in the aggregate. The excess/deficiency amounts of each nutrient is displayed in graphic forms, by symbols or animation.

1. A portable food constituent amount display calculator which, when commanded, compares the total amount of at least one constituent of foods taken in per day with the necessary amount of each said constituent a day and displays the amount of each excess or deficiency for health control, comprising
an input section provided with a character-input keyboard for inputing names of food taken in by a user during the day, and for selectively indicating a plural number of a standard amount of said at least one constituent thereof; -
A food-data memory in which said food names and each said standard amount of each said constituent thereof are prestored; means by which to read out from said food-data memory said standard amount of each said constituent of a food name which is input from the keyboard; a display which shows an input food name and each said standard amount of each said constituent read out from the food-data memory and results of comparison and arithmetic operations; an arithmetic and control section which performs said arithmetic operations, including adding the respective amounts of each said constituent of said foods taken in the day to form at least one respective total for the day for each said constituent; an all-input food data memory which stores said food names and amounts of said constituents which are displayed and each said total from said arithmetic operations; a necessary-constituent-amount memory which stores the necessary amount of each said constituent of each said stored food name; and comparison means for comparing the respective necessary amount of each said constituent and the respective total from said arithmetic operations stored in said all-input data memory. - View Dependent Claims (2, 3)

4. A system for determining the amount of each of a plurality of constituents in foods taken in by a consumer during a day, comprising
a first memory having stored therein names of foods and information on the respective amounts of each of said constituents in a standard amount of each said food having its name stored therein, a second memory having stored therein nominal recommended daily amounts of said constituents for said consumer, a keyboard section for inputing names of food consumed during the day by said consumer, and for inputing information on the amount of each said food consumed if different from said standard amount in units of said standard amount, said keyboard section including a total key, a comparison command key and a memory command key, a display for displaying each said input food name and the respective standard or different amount of each said constituent therof, a third memory for storing each said input food name and amount and current totals of each of said constituent for each said food consumed during the day, each said food with a different name having a respective different total for each said constituent thereof, and an arithmetic section for adding said displayed amounts of constituents for an input food name to the current totals in said third memory, wherein (1) when said total key is depressed while said input food name and the respective amounts of said constituents are displayed, said arithmetic section performs said adding, the displayed data is cleared, and the new totals from said adding are stored as the updated values of said current totals in said third memory, (2) when said comparison command key is operated the excess or deficiency of each said constituent for the day is calculated and displayed, and (3) when said memory read key is depressed, said stored totals from said third memory are read out and displayed in said display in a predetermined sequence.

7. A system for determing the amounts of each of a plurality of constituents in foods taken in by a consumer in each of various meals of a day, and a respective daily total for each said ingredient, said system comprising
a first memory having stored therein names of foods and information on the respective amounts of each of said constituents in a standard amount of each said food having its name stored therein, a keyboard section for inputing names of food consumed during the day by said consumer, and for inputing information on the amount of each said food consumed if different from said standard amount in units of said standard amount, said keyboard section including a total key and a memory command key, a display for displaying each said input food name and the respective standard and each said different amount of each said constituent therof, a second memory for storing each said input food name and current totals of each said constituent for each said food consumed for each said meal during the day and each said daily total, and an arithmetic section for adding said displayed amounts of constituents for an input food name to the respective current totals in said second memory, wherein (1) when said total key is depressed while said input food name and the respective amounts of said constituents are displayed, said arithmetic section performs said adding, the displayed data is cleared, and the new totals from said adding are stored as the updated values of said current totals in said second memory, and (2) when said memory read key is depressed, said stored totals from said second memory are read out and information corresponding to each said stored total read out from said second memory is displayed in said display in a predetermined sequence.
