Electric device attachable to board having electric circuit and control method thereof
First Claim
1. An electric device attachable to a board having an electric circuit and a memory, the electric device comprising:
- a connector unit configured to connect to the board;
a first voltage-supply unit configured to supply a first voltage to operate the electric circuit;
a reading unit configured to read, from the memory, first determining information on whether or not the board is compatible with the electric device;
a determining unit configured to determine whether or not the board is compatible with the electric device based on the first determining information read by the reading unit; and
a control unit configured to control the first voltage-supply unit to supply the first voltage to the electric circuit responsive to the determining unit determining that the board is compatible with the electric device, and configured to prevent the first voltage-supply unit from supplying the first voltage to the electric circuit responsive to the determining unit determining that the board is not compatible with the electric device.

Abstract
An electric device attachable to option boards and a method for controlling the same. The electric device includes option connectors for connecting to the option boards, a power unit which supplies a voltage for operating a circuit on the option boards, readers/writers which read information for determining whether or not the option boards are compatible with the electric device based on RFID tags added to the option boards, and a backup control portion which determines whether or not the option boards are compatible with the electric device based on the information read by the readers/writers. When the backup control portion determines that the option boards are compatible with the electric device, the power unit supplies the voltage to the circuit. When the backup control portion determines that the option boards are not compatible with the electric device, the power unit prevents the supply of the voltage to the circuit.

13. A control method for an electric device attachable to a board having an electric circuit and a memory, the control method comprising the following steps:
-
a reading step of reading, from the memory, first determining information on whether or not the board is compatible with the electric device;
a determining step of determining whether or not the board is compatible with the electric device based on the first determining information read in the reading step;
a first control step of controlling supply of a first voltage to operate the electric circuit responsive to determining that the board is compatible with the electric device in the determining step; and
a second control step of preventing the supply of the first voltage responsive to determining that the board is not compatible with the electric device in the determining step. - View Dependent Claims (14, 15, 16, 17, 18, 19)
