ROTATION OTG USB MEMORY DEVICE

The present invention relates to a rotary OTG USB memory device, and more particularly, to an OTG USB memory constituting a first port terminal, a second port terminal, and a portable terminal connection terminal in a USB case. The rotary OTG USB memory device stores PC data in a memory by exposing the first port terminal (115) to the outside of the USB case and connecting the first port terminal to the PC port terminal formed on a USB port. The rotary OTG USB memory device supplies the data stored in the memory to the portable terminal connection terminal by pulling, moving the first port terminal (115) to the inside after rotating the first port terminal unit, and connecting the first port terminal to the second port terminal formed in the USB case. The rotation OTG USB memory device supplies the data to the portable terminal, which is connected to the portable terminal connection terminal.
