Electronic device, non-transitory computer-readable medium storing program, and circuit chip
First Claim
1. An electronic device connected or disposed with an external storage medium, the electronic device comprising:
- a connector unit that is connected to an external device;
a transmission channel that is connected to the connector unit to transmit data from the external device;
a data processing unit that is connected to the transmission channel; and
a data transferring unit that is connected to the transmission channel, the data transferring unit including a switching function allowing or blocking passage of the data transmitted from the transmission channel, so as in case of writing the data into the external storage medium, the data transferring unit sending a disconnection request to the data processing unit, the disconnection request being for blocking input of the data by making a port of the data processing unit high impedance, and after receiving a disconnection notification from the data processing unit, the data transferring unit allowing passage of the data transmitted from the transmission channel to transfer the data to the external storage medium, whereinthe data transferring unit receives a notification that the external device is connected to the connector unit, and generates an inquiry representing whether the data are input to the data processing unit or input to the data transferring unit, based on the notification that the external device is connected to the connector unit, andthe data transferring unit allows the passage of the data while the data processing unit is disconnected from the transmission channel and the external device.

Abstract
The present invention relates to data transfer to an external storage device disposed on or connected to an electronic device and can accelerate the data transfer. The present invention relates to an electronic device (portable terminal device) connected or disposed with an external storage device, includes a transmission channel connected to an external device (personal computer) that is a data source to transmit data, and simplifies a data transmission path intervening between the transmission path and the external storage device to accelerate the data transfer and accelerate the writing of data into the external storage device.
