PORTABLE MACHINE
PROBLEM TO BE SOLVED: To provide a portable machine which does not deteriorate antenna communication performance of a transponder coil, and which does not worsen an antenna characteristic of an antenna for answer signal transmission.SOLUTION: A portable machine includes: first communication means 1 for transmitting a first transmission signal 1a to a vehicle side; second communication means 2 for transmitting a second transmission signal 2a by responding to an electromagnetic field from the vehicle side; a control unit 15 for controlling the first communication means 1 and the second communication means 2; and a circuit board 9. The first communication means 1 has a loop type antenna 7 comprising a conductor wire 7a formed on the circuit board 9. The second communication means 2 has a substantially rectangle-shaped transponder coil 6 disposed on the circuit board 9. One short side 6a of the transponder coil 6 is arranged on an end part 9a on the side facing a vehicle 50 of the wiring board 9. The conductor wire 7a is formed so as to go in/come out of a side in the longitudinal direction in a region projected to the circuit board 9 of the transponder coil 6.SELECTED DRAWING: Figure 5
【課題】トランスポンダコイルのアンテナ交信性能を劣化させず、アンサー信号送信用のアンテナのアンテナ特性を悪化させないようにした携帯機を提供する。【解決手段】第１送信信号１ａを車両側に送信する第１通信手段１と、車両側からの電磁界に応答して第２送信信号２ａを送信する第２通信手段２と、第１通信手段１及び第２通信手段２を制御する制御部１５と、回路基板９と、を備え、第１通信手段１は、回路基板９に形成された導体線７ａからなるループ型アンテナ７を有し、第２通信手段２は、回路基板９上に配設された略長方形形状をしたトランスポンダコイル６を有しており、トランスポンダコイル６の一方の短辺６ａが配線基板９の車両５０に向く側の端部９ａに配置され、導体線７ａは、トランスポンダコイル６の回路基板９へ投影した領域の長手方向の辺から出入りしているように形成されている。【選択図】図５
