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
