- ROM read-only memory
- the second casing K 5 2 is provided with a transmission / reception unit 5 2 1, an internal wireless communication antenna 5 2 2, a camera 5 2 3, a liquid crystal display unit 5 2 4, and an additional device 5 2 5. .
- the first housing K 5 1 and the second The casing K 5 2 is connected so that the positional relationship between the first casing ⁇ 51 and the second casing ⁇ 52 can be changed.
- the communication environment detection unit 509 detects the communication environment based on the received signal received via the external wireless communication antenna 5101.
- a bit error rate or the like can be used in the case of a digital signal, and a signal-to-noise ratio or a distortion rate can be used in the case of an analog signal.
- the power control unit 5 1 1 controls the output power of the radio wave transmitted from the external wireless communication antenna 5 0 1 based on the communication environment detected by the communication environment detection unit 5 09.
- the power control unit 5 10 controls the output power of the radio wave transmitted from the internal non-fountain communication antenna 5 8 8 based on the control result by the power control unit 5 11.
- the controller 5 0 4 notifies the power controller 5 1 0 of the transmission timing when transmitting the transmission data. Then, when the transmission timing of the transmission data is notified from the control unit 50 4, the power control unit 5 10 generates the transmission timing signal S 51 and transmits the transmission timing signal S 51 to the transmission / reception unit 5 0. Output to 7. Then, when the transmission / reception unit 5 07 receives the transmission timing signal S 5 1 from the power control unit 5 10, the transmission / reception unit 5 0 7 increases the output power of the radio wave output from the internal wireless communication antenna 4 0 8, Internal wireless communication is performed between the first casing K 5 1 and the second casing K 5 2.
- -Communication environment detection unit 5 When communication environment force is detected at - ⁇ 9, -V 'the detection result is sent to the power control unit 5 1 1. Then, when the communication environment is deteriorated, the power control unit 51 1 instructs the wireless unit 5 0 2 to increase the output power of the radio wave output from the external wireless communication antenna 5 0 1. Then, when instructed to increase the output power from the power control unit 5 11, the radio unit 50 2 increases the output power of the radio wave output from the external radio communication antenna 5 0 1.
- the power control unit 51 1 increases the output power of the radio wave output from the internal radio communication antenna 5 08 when the output power of the radio wave output from the external radio communication antenna 5 0 1 is increased.
- the power control unit 5 1 0 is instructed to do so.
- the power control unit 5 1 0 increases the output power of the radio wave output from the external wireless communication antenna 5 0 8. Sending and receiving Nobu 5 5 Instruct 7.
- the transmitter / receiver 5 07 responds to the increase in the output power of the radio wave output from the external wireless communication antenna 5 0 1.
- the output power of the radio wave output from the internal wireless communication antenna 5 0 8 can be increased.
