DATA WRITE DEVICE AND DATA WRITE METHOD
First Claim
1. A data write device that receives power supply from a first system guided from a power source and writes data in a nonvolatile first storage unit, the data write device comprising:
- a request generation unit that generates a write request to write data in the first storage unit under a predetermined condition;
a receiving unit that receives the write request from a user;
a second storage unit that receives power supply from a second system guided from the power source and is able to store data;
a first write unit that writes target data to be written, which is stored in the second storage unit, in the first storage unit in response to the write request;
a second write unit that writes the target data which is stored in the second storage unit, in the first storage unit if the power supply from the first system is stopped and then restarted at the time of writing by the first write unit; and
a display control unit that causes a display device which carries out predetermined initial display when the power supply from the first system is stopped and then restarted, to display a write result of the target data in the first storage unit,wherein the second write unit is activated when the request generation unit generates the write request and is not activated when receiving the write request from the user.

Abstract
A data write device receives power supply from a first system guided from a power source and writes data in a nonvolatile first storage unit. A request generation unit generates a write request to write data in the first storage unit under a predetermined condition. A receiving unit receives the write request from a user. A second storage unit receives power supply from a second system guided from the power source and is able to store data. A first write unit writes target data to be written, which is stored in the second storage unit, in the first storage unit in response to the write request. A second write unit writes the target data which is stored in the second storage unit, in the first storage unit if the power supply from the first system is stopped and then restarted at the time of writing by the first write unit. A display control unit causes a display device which carries out predetermined initial display when the power supply from the first system is stopped and then restarted, to display a write result of the target data in the first storage unit. The second write unit is activated when the request generation unit generates the write request and is not activated when receiving the write request from the user.

8. A data write method of a data write device that receives power supply from a first system guided from a power source and writes data in a nonvolatile first storage unit, the data write method comprising:
-
a request generation step of generating a write request to write data in the first storage unit under a predetermined condition; a receiving step of receiving the write request from a user; a first write step of writing target data to be written, which is stored in a second storage unit that receives power from a second system guided from the power source and is able to store data, in the first storage unit in response to the write request; a second write step of writing the target data which is stored in the second storage unit, in the first storage unit if the power supply from the first system is stopped and then restarted at the time of writing by the first write unit; and a display control step of causing a display device which carries out predetermined initial display when the power supply from the first system is stopped and then restarted, to display a write result of the target data in the first storage unit, wherein the second write step is carried out when the request generation unit generates the write request and is not carried out when receiving the write request from the user.
