COMMUNICATION SYSTEM
First Claim
1. A communication system that establishes non-contact data communication between a portable terminal and a cradle on which the portable terminal is placed, the system comprising:
- the portable terminal including a first communication unit establishing non-contact data communication with the cradle, an open state detection unit detecting an open state of the portable terminal, and a first control unit that activates the first communication unit as a result of the open state detection unit having detected an open state of the portable terminal; and
the cradle including a second communication unit establishing non-contact data communication with the portable terminal, an opened terminal detection unit detecting that the opened portable terminal is placed, and a second control unit that activates the second communication unit as a result of the opened terminal detection unit having detected placement of the portable terminal remaining in an open state.

Abstract
In a communication system that performs recharging operation and short-range data communication between a portable terminal and a cradle, when a communication unit of the cradle is halted for power saving purpose, there is no unit available to activate the communication unit of the cradle through operation of the portable terminal when data communication is commenced while the portable terminal remains placed in the cradle. A first control unit 22 activates a first communication unit 24 according to an output of an open state detection unit 23 that detects an open state of a portable terminal 20. A second control unit 27 activates a second communication unit 26 of the cradle according to an output of an opened terminal detection unit 25 that detects placement of the opened portable terminal 20. As a result, the first communication unit 24 and the second communication unit 26 are activated by opening the portable terminal 20, whereby bidirectional communication can be established therebetween.

8. A communication system that establishes non-contact data communication between a portable terminal and a cradle on which the portable terminal is placed, the system comprising:
-
the portable terminal including a first communication unit establishing non-contact data communication with the cradle, an operation unit by which operation for activating the first communication unit is performed, a notifying unit for notifying the cradle that the first communication unit is activated, and a first control unit that activates the first communication unit and the notifying unit in accordance with operation of the operation unit; and the cradle including a second communication unit establishing non-contact data communication with the portable terminal, a terminal detection unit detecting a notification from the notifying unit, and a second control unit that activates the second communication unit as a result of the terminal detection unit having detected an activated state of the first communication unit. - View Dependent Claims (9, 14, 17)
