A tape feeder includes a magnet that rotates as one with a sprocket driven by a motor, two magnetic field detecting elements that detect signals in accordance with a magnetic field from the magnet and that are arranged at positions opposite the rotation region of the magnet, and a rotation angle detecting circuit that detects the rotation angle of the magnet and the rotation angle of the sprocket by processing output signals of the magnetic field detecting elements. A control section of the tape feeder reads the detection information of the rotation angle detecting circuit from immediately after the motor is started, recognizes the rotation angle of the sprocket, detects the position of tooth of the sprocket of the tooth engaged with a feeding hole of component supply tape based on the recognition results of the rotation angle of the sprocket for each pitch feeding operation of the sprocket, and corrects the pitch feeding amount of the motor by a pitch error correcting amount set for the tooth.

Tape feeder and component mounter

Electronic component supply device of the present invention includes multiple feeders each having an individual control section configured to operate by use of operation software to control a tape feeding mechanism, a host control section capable of holding update software configured to be replaced with at least part of the operation software, and multiple information transmission sections connected between the host control section and the individual control sections of the multiple feeders so as to transmit information and configured to transmit the update software from the host control section to the individual control sections independently of one another. According to this configuration, the multiple information transmission sections can transmit the update software to the different feeders in parallel in terms of time, whereby the updating time can be shortened significantly compared with a case where update software is transmitted sequentially to multiple feeders.

Electronic component supply device

In a board work system, the CPU of a board work device transmits error related information which relates to an error in a case where the error has occurred in the own device. Then, the CPU receives the error related information which relates to the error of the other board work device, and stores the received error related information in the HDD. Then, the display operation section is controlled such that information (other device error notification screen) based on the stored error related information is notified to the operator in a case where the power source of the board work device (other board work device), in which the error has occurred, is detected to be switched off.
