<P>PROBLEM TO BE SOLVED: To provide a data communication terminal that includes multiple antennas, is small in external dimensions when not in use, and can be directly fit to a PC in an easily detachable manner. <P>SOLUTION: Data communication terminal includes closures 1, 2 which can be slid in a prescribed direction with each other, and antennas 11, 21 are arranged at a one-side end (left end in Figure 1) in the prescribed direction in the closures 1, 2, respectively. The closures 1, 2 are slid with each other as in Figure 1(B) in a communication-enabled state. At this time, the antennas 11, 21 have different positions with each other regarding the prescribed direction, and mutual interference is reduced. The closure 1 has a USB interface 3 at the other end (right end of Figure 1). Because the USB interface 3 projects more outside than the other end (right end of Figure 1) of the closure 2 when the closures 1, 2 are slid with each other to the communication-enabled state as in Figure 1(B), it can be easily attached to or detached from the USB interface of a PC. When it is not used, both ends of the closures are aligned as in Figure 1(A), and it becomes small. <P>COPYRIGHT: (C)2013,JPO&INPIT |
