Abstract

Abstract An electronic record keeping device for recording numerical data under different items. The device has a casing and a memory having a plurality of sections. The number of the sections corresponds to the number of items. Each section has a first memory area for storing a budget data and a second memory area for storing a cumulative expenditures. A key board provided on the casing has number keys for effecting the input of a numerical data, a plurality of item keys for effecting an access to a corresponding section in the memory upon depression of one item key, a mode key for changing the mode between a first mode for entering the budget data in the first memory area, and the second mode for entering the cumulative expenditure in the second memory area. A display is provided for displaying a numerical data inputted by the number keys, and a controller is provided to operate in response to a depression of one of the item keys such that, while the first mode is established, a numerical data as inputted by the number keys is entered and stored in the first memory area as the budget data, and that, while the second mode is established, a numerical data as inputted by the number keys is added to the cumulative expenditure previously stored in the second memory area in the second memory area.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 279 words
An electronic record keeping device for recording numerical data under different items, comprising: a casing; memory means having a plurality of sections, a number of sections corresponding to a number of items, each section having a first memory area for storing a first numerical data and a second memory area for storing a second numerical data; a key board on said casing having: number keys for effecting the input of a numerical data, a plurality of item keys for effecting an access to a corresponding section in said memory means upon depression of one item key, a mode key for changing between a first mode for entering the first numerical data in said first memory area, and a second mode for entering the second numerical data in said second memory area, a balance key for obtaining a difference between said first and second numerical data of an item when said balance key and item are depressed, and wherein a depressed effect of said balance key being maintained after different item keys are depressed; display means for displaying at least a numerical data inputted by said number keys; and control means, operated in response to depression of one said item keys such that, while said first mode is established, a numerical data as inputted by said number keys is entered and stored in said first memory area as the first numerical data, and that, while said second mode is established, a numerical data as inputted by said number keys is added to a second numerical data previously stored in said second memory area and the added result is stored as a cumulated second numerical data in said second memory area.
Claim 2
Dependent Claim 279 words
An electronic record keeping device for recording numerical data under different items, comprising: a casing; memory means having a plurality of sections, a number of sections corresponding to a number of items, each section having a first memory area for storing a first numerical data and a second memory area for storing a second numerical data; a key board on said casing having: number keys for effecting the input of a numerical data, a plurality of item keys for effecting an access to a corresponding section in said memory means upon depression of one item key, a mode key for changing between a first mode for entering the first numerical data in said first memory area, and a second mode for entering the second numerical data in said second memory area, a balance key for obtaining a difference between said first and second numerical data of an item when said balance key and item are depressed, and wherein a depressed effect of said balance key being maintained after different item keys are depressed; display means for displaying at least a numerical data inputted by said number keys; and control means, operated in response to depression of one said item keys such that, while said first mode is established, a numerical data as inputted by said number keys is entered and stored in said first memory area as the first numerical data, and that, while said second mode is established, a numerical data as inputted by said number keys is added to a second numerical data previously stored in said second memory area and the added result is stored as a cumulated second numerical data in said second memory area.
Claim 3
Dependent Claim 284 words
An electronic record keeping device for recording numerical data under different items, comprising: a casing; memory means having a plurality of sections, a number of sections corresponding to a number of items, each section having a first memory area for storing a first numerical data and second memory area for storing a second numerical data; a key board on said casing having: number keys for effecting the input of a numerical data, a plurality of item keys for effecting an access to a corresponding section in said memory means upon depression of one item key, a mode key for changing between a first mode for entering the first numerical data in said first memory area, and a second mode for entering the second numerical data in said second memory area, a percentage key for obtaining a percentage of said second numerical data with respect to said first numerical data of an item when said percentage key and item key are depressed, a depressed effect of said percentage key being maintained after different item keys are depressed; display means for displaying at least a numerical data inputted by said number keys; and control means, operated in response to a depression of one of said item keys such that, while said first mode is established, a numerical data as inputted by said number keys is entered and stored in said first memory area as the first numerical data, and that, while said second mode is established, a numerical data as inputted by said number keys is added to a second numerical data previously stored in said second memory area and the added result is stored as a cumulated second numerical data in said second memory area.
Claim 4
Dependent Claim 284 words
An electronic record keeping device for recording numerical data under different items, comprising: a casing; memory means having a plurality of sections, a number of sections corresponding to a number of items, each section having a first memory area for storing a first numerical data and second memory area for storing a second numerical data; a key board on said casing having: number keys for effecting the input of a numerical data, a plurality of item keys for effecting an access to a corresponding section in said memory means upon depression of one item key, a mode key for changing between a first mode for entering the first numerical data in said first memory area, and a second mode for entering the second numerical data in said second memory area, a percentage key for obtaining a percentage of said second numerical data with respect to said first numerical data of an item when said percentage key and item key are depressed, a depressed effect of said percentage key being maintained after different item keys are depressed; display means for displaying at least a numerical data inputted by said number keys; and control means, operated in response to a depression of one of said item keys such that, while said first mode is established, a numerical data as inputted by said number keys is entered and stored in said first memory area as the first numerical data, and that, while said second mode is established, a numerical data as inputted by said number keys is added to a second numerical data previously stored in said second memory area and the added result is stored as a cumulated second numerical data in said second memory area.
