Patent ID: 6932629

Claim:
A device with a USB terminal comprising: a device main body including a USB terminal; and a cap including a housing space for housing at least the USB terminal, the device main body and the cap being assembled so that they can be moved in an extending or compressing manner relative to each other by inserting at least the USB terminal to the housing space, or can be rotated relative to each other in an extended state, the cap including a base member, and a top plate and a bottom plate facing each other, the top plate and bottom plate being supported by the base member, and the housing space being formed by the base member, the top plate, and the bottom plate, projections used for slidable rotation being formed on one of an internal surface of at least one of the top plate and the bottom plate, and at least one of an upper surface and a lower surface of the device main body, and slidable rotation guide grooves, in which the projections are inserted, being formed on the other, each of the slidable rotation guide grooves including a circular groove portion, which is substantially circular, and guide groove portions formed to be integral with the circular groove portions and extending in a compressing or extending direction of the device main body and the cap, the device main body and the cap being moved in the extending or compressing manner relative to each other when the projections are moved between the guide groove portions and the circular groove portions, and being rotated relative to each other when the projections are slid in the circular groove portions, and at a first position where the device main body and the cap are close to each other, the projections being located in the guide groove portions, at a second position where the device main body and the cap have been moved so as to be away from each other, the projections being located in the circular groove portions, a third position of the device main body and the cap being achieved when the projections are rotated from the second position within the circular groove portions, and a fourth position being achieved when the projections are reversely moved in the guide groove portions from the third position.
