In each apparatus, the cover member 2 that covers the upstream and downstream side surfaces in the substrate transport direction (X direction) is positioned at the upstream and downstream ends of the substrate transport unit 8, and the substrate 9 passes therethrough. An opening 3 is provided for this purpose. A signal tower 6 for notification is arranged on the upper side of the cover member 2 provided on the ceiling surface of the apparatus. Here, the signal tower 6 has a tilting structure, and is mounted and used in a posture in which the signal tower 6 is tilted to the device side to which the signal tower 6 belongs. Thereby, even when the devices having the same configuration are densely arranged with a short connection pitch, the operator does not mistake the device to which the signal tower 6 belongs when the signal tower 6 is operated.

  The side surface in the Y direction of each device, that is, the device side surface along the substrate transport direction (X direction) is an operation surface on which the operator operates the device, and various operation switches are provided on the operation surface.

At this time, the control unit 22 executes an emergency stop process that immediately stops the operation of the substrate transport unit 8 and the mounting unit 20 of the device to which the control unit 22 belongs, and the operation unit 4 (L) is biased from the center position in the device. Control processing for emergency stop of the adjacent device M * with the operation unit 4 (L) sandwiched between the one direction side (FIG. 3B and the right direction side in the example shown in FIG. 5). Perform together.

  That is, the control unit 22 transmits an emergency stop signal to the adjacent device M * via the communication unit 21 of the device. The emergency stop signal is transmitted to the control unit 22 of the apparatus M * via the communication unit 21 of the apparatus M *, and the control unit 22 is used to stop the operation of the substrate transfer unit 8 and the mounting unit 20 of the apparatus M *. Process. As a result, the device M * that causes an abnormal operation and requires an emergency stop immediately stops its operation. Therefore, the operation purpose of stopping the operation of the device M * is achieved despite the fact that the operator is performing an erroneous action / operation of accessing the device M (L) adjacent to the left side by mistake. Safety is ensured.

  In other words, in each of the devices M1 to M6 shown in the present embodiment, if there is an operation input of the emergency stop switch 4b, the control unit 22 switches the operation unit 4 together with the device having the operation input. In this case, it functions as a device stop control processing unit that performs control processing for emergency stop of the device adjacent to the one direction. In the emergency stop method for the electronic component mounting apparatus shown in the present embodiment, if there is an operation input of the emergency stop switch 4b, the operation unit 4 is moved together with the electronic component mounting apparatus having the operation input. The control unit 22 performs control processing for emergency stopping the electronic component mounting apparatus adjacent to the one direction side.

  In the example shown in the present embodiment, an electronic component mounting apparatus that performs a component mounting operation for mounting an electronic component on a substrate is shown as an example of an electronic component mounting apparatus. The present invention can also be applied to a solder printing device that prints electronic component joining solder on a substrate, an inspection device that inspects a substrate, and the like.

  The electronic component mounting apparatus and the electronic component mounting apparatus emergency stop method according to the present invention have the effect that the safety of the operator can be reliably ensured in equipment having a configuration in which small and thin unit devices are connected.
