A substrate working device comprising: a transportation portion performing introduction/discharge of a substrate loaded with an electronic component; a working portion performing prescribed work processing on the substrate by automatic running; and a control portion configured to perform an operator operation request requesting an operator to perform a prescribed operation in response to the status of the automatic running while acquiring a compatibility/incompatibility status of the operator as to whether or not the operator is present and compatible with the operator operation request, characterized in that the control portion is configured to perform control of switching a running mode for the automatic running to a normal mode in a case where the operator is present and compatible and in a case where the operator is not compatible switching the running mode to a continuation preference mode of such a running condition that the operator operation request is harder to generate than in the normal mode, in at least either one of an error stop condition for the automatic running and a working speed condition for automatic running, in response to the compatibility/incompatibility status, and the substrate working device is so configured that whether or not to perform stoppage according to an error response request is determined on the basis of an error determination threshold at which an error determination is harder to perform in the continuation preference mode than in the normal mode as the error stop condition, and/or the running is performed in the continuation preference mode at a working speed setting set to a lower speed than in the normal mode as the working speed condition. a transportation portion performing introduction/discharge of a substrate loaded with an electronic component; a working portion performing prescribed work processing on the substrate by automatic running; and a control portion configured to perform an operator operation request requesting an operator to perform a prescribed operation in response to the status of the automatic running while acquiring a compatibility/incompatibility status of the operator as to whether or not the operator is present and compatible with the operator operation request, characterized in that the control portion is configured to perform control of switching a running mode for the automatic running to a normal mode in a case where the operator is present and compatible and in a case where the operator is not compatible switching the running mode to a continuation preference mode of such a running condition that the operator operation request is harder to generate than in the normal mode, in at least either one of an error stop condition for the automatic running and a working speed condition for automatic running, switching a running mode for the automatic running to a normal mode in a case where the operator is present and compatible and in a case where the operator is not compatible switching the running mode to a continuation preference mode of such a running condition that the operator operation request is harder to generate than in the normal mode, in at least either one of an error stop condition for the automatic running and a working speed condition for automatic running, in response to the compatibility/incompatibility status, and the substrate working device is so configured that whether or not to perform stoppage according to an error response request is determined on the basis of an error determination threshold at which an error determination is harder to perform in the continuation preference mode than in the normal mode as the error stop condition, and/or the running is performed in the continuation preference mode at a working speed setting set to a lower speed than in the normal mode as the working speed condition. whether or not to perform stoppage according to an error response request is determined on the basis of an error determination threshold at which an error determination is harder to perform in the continuation preference mode than in the normal mode as the error stop condition, and/or the running is performed in the continuation preference mode at a working speed setting set to a lower speed than in the normal mode as the working speed condition.
