1. A communication terminal comprising:
- a first antenna unit;
a second antenna unit;
a connection unit configured to electrically connect the first antenna unit and the second antenna unit to each other; and
a hand-held housing;
wherein each of the first antenna unit and the second antenna unit operates with a signal used in one information processing system; and
the signal received by the first antenna unit is transmitted from the second antenna unit, and the signal received by the second antenna unit is transmitted from the first antenna unit without using a battery; and
the first antenna unit is a far field dipole antenna wirelessly coupled to a reader/writer, and the second antenna unit is a near field loop antenna wirelessly coupled to a wireless IC tag;
and the first antenna unit is located at a trailing end portion of the hand-held housing and the second antenna unit is located at a leading end portion of the hand-held housing opposite to the trailing end portion of the hand-held housing;
wherein the first antenna unit, the second antenna unit, and the connection unit are housed in the hand-held housing.

Abstract
An information processing system includes a reader/writer, a communication terminal, and a wireless IC tag. The communication terminal includes an electric field-type first antenna unit, a magnetic field-type second antenna unit, and a connection unit electrically connecting the first and second antenna units and to each other, and is housed within a pen housing. The first antenna unit is coupled to an antenna of the reader/writer through an electric field, and the second antenna unit is coupled to the wireless IC tag through a magnetic field. By causing the second antenna unit to be adjacent to the wireless IC tag, the reader/writer and the wireless IC tag communicate with each other.

6. An information processing system comprising:
-
a reader/writer; at least one communication terminal; and a plurality of wireless IC tags;
wherein the at least one communication terminal includes a first antenna unit, a second antenna unit, a connection unit configured to electrically connect the first antenna unit and the second antenna unit to each other, and a hand-held housing;
wherein the first antenna unit communicates with the reader/writer;the second antenna unit communicates with one of the plurality of wireless IC tags; and information stored in the one of the plurality of wireless IC tags is read using the reader/writer; and the first antenna unit is a far field antenna wirelessly coupled to the reader/writer, and the second antenna unit is a near field antenna wirelessly coupled to the one of the plurality of wireless IC tags; the first antenna unit is located at a trailing end portion of the hand-held housing and the second antenna unit is located at a leading end portion of the hand-held housing opposite to the trailing end portion of the hand-held housing; and the second antenna unit selectively communicates with the one of the plurality of wireless IC tags by placing the leading end portion of the hand-held housing closer to the one of the plurality of wireless IC tags than to remaining ones of the plurality of wireless IC tags; wherein the first antenna unit, the second antenna unit, and the connection unit are housed in the hand-held housing. - View Dependent Claims (7, 8, 9, 10)
