Abstract
Abstract There is provided a device for feeding out data, while classifying the data according to the kind thereof for use in a calculator. The device comprises a data output means for feeding out data, data storing means, discrimination means for discriminating the data whether the data are of one kind or of the other kind, and shifting means for shifting the data to be fed out up to the most significant digit or the least significant digit of the data output means depending upon the kinds of the data to be fed out.

Claim 1
Independent Claim
286 words
An output device for a calculator for classifying and feeding out data comprising: a key board including data entry keys and instruction keys for entering instruction entry signals; operating means for executing an operation in accordance with the data entered by the entry keys and the instruction entered by the instruction keys; data storing means for storing the data entered by the entry keys and operational result produced by the operating means; output means having a predetermined number of output positions for feeding out the data in the storing means; discriminator means for discriminating a most significant digit designating signal by which the instruction signal entered by the instruction keys designates to output the data in the storing means so that the most significant digit of the data is in alignment with a first specified digit of the output digits of the output means and a least significant digit designating signal by which the instruction signal entered by the instruction keys designates to output the data in the storing means so that the least significant digit of the data is in alignment with a second specified digit of the output digits of the output means; and means for supplying to the output means the data in the storing means aligning the most significant digit of the data with the first specified digit of the output digits of the output means when the discriminator means discriminates the most significant digit designating signal and for supplying to the output means the data in the storing means aligning the least significant digit of the data with the second specified digit of the output digits of the output means when the discriminator means discriminates the least significant digit designating signal.

An output device for a calculator for classifying and feeding out data comprising: a key board including data entry keys and instruction keys for entering instruction entry signals; operating means for executing an operation in accordance with the data entered by the entry keys and the instruction entered by the instruction keys; data storing means for storing the data entered by the entry keys and operational result produced by the operating means; output means having a predetermined number of output positions for feeding out the data in the storing means; discriminator means for discriminating a most significant digit designating signal by which the instruction signal entered by the instruction keys designates to output the data in the storing means so that the most significant digit of the data is in alignment with a first specified digit of the output digits of the output means and a least significant digit designating signal by which the instruction signal entered by the instruction keys designates to output the data in the storing means so that the least significant digit of the data is in alignment with a second specified digit of the output digits of the output means; and means for supplying to the output means the data in the storing means aligning the most significant digit of the data with the first specified digit of the output digits of the output means when the discriminator means discriminates the most significant digit designating signal and for supplying to the output means the data in the storing means aligning the least significant digit of the data with the second specified digit of the output digits of the output means when the discriminator means discriminates the least significant digit designating signal.
Claim 3
Dependent Claim
15 words
An output device as defined in claim 1, wherein the output means comprises a printer.
Claim 4
Dependent Claim
17 words
An output device as defined in claim 1, wherein the output means comprises an optical display device.
Claim 5
Dependent Claim
29 words
An output device as defined in claim 1, wherein an order signal having the most significant digit designating signal is a signal for designating, to require the operational result.
Claim 6
Dependent Claim
76 words
An output device as defined in claim 1, wherein the sorting means comprises shifting means for storing the operational result and the entered data aligning the leaSt significant digit thereof with that of output digits of the storing means and for shifting the operational result and the entered data to align the most significant digit thereof with that of output digits of the storing means when the discriminator means discriminates the most significant digit designating signal.
Claim 7
Dependent Claim
52 words
An output device as defined in claim 5, wherein storing means comprises means for converting into a redundancy code the digit information of a less significant digit or digits of the information stored in the storing means by the digit number corresponding to the number shifted to align the most significant digit.
