ELECTRONIC APPARATUS AND METHOD
First Claim
1. An electronic apparatus comprising a first device and a second device, whereinthe first device is electrically connected to the second device in a detachable manner,the first device comprises a CPU which executes a driver to recognize and to control an operation input device, and a first controller which receives a command output from the driver to the operation input device and to control the operation input device,the second device comprises the operation input device, and a second controller which receives a command transmitted from the first controller and to control the operation input device, andwhen the first device is not electrically connected to the second device, the driver maintains a state in which the driver recognizes the operation input device of the second device to be a device connected to the first device, and after the driver transmits a command to the operation input device, the first controller transmits to the driver a reply to the transmitted command instead of the second controller.
