Abstract: A board manufacturing system includes an autonomous mobile cart configured to transport an object used in board work devices of a mounting line, a robot arm provided on the autonomous mobile cart and configured to transport the object used in the board work devices to the board work devices, and a controller provided in the autonomous mobile cart and configured or programmed to control driving of the robot arm. The controller is configured or programmed to control the driving of the robot arm such that the robot arm transports the object used in the board work devices into and out of the board work devices within a movable range of a working unit in the board work devices in a plan view.

Abstract: A component feeding device includes a tape lead-in mechanism that leads a component storage tape into a tape traveling path. A pair of tape holding portions are coupled to an operating lever such that the pair of tape holding portions are allowed to shift in posture between a holding posture in which the pair of tape holding portions are able to hold the component storage tape and a hold releasing posture in which the pair of tape holding portions release their hold on the component storage tape. As a result of turning together with the turned operating lever, the pair of tape holding portions shift in position between a send-off enabling position and a send-off disabling position at which the component storage tape is released from a state of being sent off. At the send-off disabling position, the pair of tape holding portions takes the hold releasing posture.

Abstract: A jam prevention mechanism includes a used tape guide with a guide surface along which a used tape fed out from a tape feeder is guided in a guide direction following a longitudinal direction of the used tape. A pressing member presses, against the guide surface, the used tape guided along the guide surface. A support member removably supports the pressing member.
