Abstract

Provided is an electronic device including: a communication unit used for communicating with an external device; an input device having a plurality of keys for accepting an input operation of data used for an arithmetic operation; an output device that outputs information; a memory; and at least one processor that causes the output device to provide notice of first information in the case where numerical data for use in the arithmetic operation is received from the external device via the communication unit.

First claim

What is claimed is:

1. An electronic device comprising:
a communication unit used for communicating with an external device;
an input device having a plurality of keys for accepting an input operation of data used for an arithmetic operation; and
a processor that causes an output device to provide notice of first information indicating that numerical data for the arithmetic operation has been received via the communication unit,
wherein, in the case of receiving unavailable data containing data different from numerical values via the communication unit, the processor causes the output device to provide notice of the second information indicating that the unavailable data has been received.

2. The electronic device according to claim 1 , wherein:
the numerical data used in the arithmetic operation are numerical data composed of numerical values having a predetermined number of digits or less; and
the unavailable data is data containing a sign different from a numerical value.

3. The electronic device according to claim 1 ,
wherein the processor displays the first information on a first part of the output device and the second information on a second part different from the first part of the output device.

4. The electronic device according to claim 1 , wherein:
the input device includes a first operation key for inputting the numerical data for use in the arithmetic operation and a second operation key for providing an instruction to perform a specific operation; and
the processor causes:
the output device to output the numerical data whose input was accepted in the case where the input of the numerical data for use in the arithmetic operation is accepted by the operation of the first operation key; and
the output device to provide notice of third information different from the first information and from the second information in the case where the specific operation is performed by the operation of the second operating key.

5. The electronic device according to claim 4 , wherein the processor causes:
the output device to display a first symbol that serves as the first information in the case where the numerical data is received from the external device; and
the output device to display a second symbol that is different from the first symbol and serves as the third information in the case where the specific operation is performed.

6. The electronic device according to claim 4 , wherein:
the output device includes a first display and a second display; and
the processor causes:
the first display to display the first information; and
the second display to display the third information.

7. The electronic device according to claim 1 , further comprising a memory provided with a key transfer memory storage area for storing the numerical data received from the external device,
wherein the processor stores the numerical data received from the external device into the key transfer memory storage area and then causes the output device to provide notice of the first information.

8. The electronic device according to claim 7 , wherein:
the memory is provided with an operand storage area in which a numerical value used for an arithmetic operation is stored; and
the processor stores the numerical data received from the external device into the key transfer memory storage area and then stores the numerical data into the operand storage area.

9. The electronic device according to claim 8 , wherein:
the input device includes a third operation key for inputting an operator for the four arithmetic operations used in the arithmetic operation and a fourth operation key for inputting an operator for providing an instruction to perform an arithmetic operation; and
after receiving the numerical data from the external device, the received numerical data is stored in the operand storage area before the third and fourth operation keys are operated.

10. A control method in an electronic device that includes a communication unit used for communicating with an external device, an input device having a plurality of keys for accepting an input operation of data used for an arithmetic operation, and a processor that causes an output device to provide notice of first information indicating that numerical data for the arithmetic operation has been received via the communication unit,
wherein, in the case of receiving unavailable data containing data different from numerical values via the communication unit, the processor causes the output device to provide notice of the second information indicating that the unavailable data has been received.

11. A non-transitory computer-readable recording medium for storing a control program that configures a computer of an electronic device to cause an output device to provide notice of second information indicating that unavailable data has been received in the case of receiving unavailable data containing data different from numerical values via a communication unit,
wherein the electronic device includes a communication unit used for communicating with an external device and an input device having a plurality of keys for accepting an input operation of data used for an arithmetic operation and causes the output device to provide notice of first information indicating that numerical data for the arithmetic operation has been received via the communication unit.
