Electronic component mounter and electronic component mounting system

The invention provides an electronic component mounter and an electronic component mounting system, which can monitor the deterioration state of the conveyer belt in a state where it is mounted on the electronic component mounting apparatus. The electronic component mounter having a mounting head includes: a board transporter (transport mechanism) that transports a board with a transport belt supporting the board; a recognizer (a board recognition camera or a height sensor) that is provided in the mounting head and recognizes a state of a front surface of the transport belt; and a determiner (wear determiner) that determines a degradation state (wear degree) of the transport belt based on the state of the front surface of the transport belt recognized by the recognizer. 本发明提供种电子部件安装装置以及电子部件安装系统，能够在装配于电子部件安装装置的状态下监视搬送带的劣化状态。具有安装头的电子部件安装装置具备：基板搬送部(基板搬送机构)，由搬送带支撑并搬送基板；辨识单元(基板辨识摄像机或者高度传感器)，配备于安装头，对搬送带的表面状态进行辨识；和判定单元(磨损判定部)，根据辨识单元辨识出的搬送带的表面状态来判定搬送带的劣化状态(磨损状况)。
