摘要：PURPOSE:To constitute the sewing machine so that even if thread entanglement is generated, it is possible to cope easily therewith, and also, the work can be executed safely by executing a manual rotation of a hook by connecting a hand pulley to the hook, and also, deciding whether a state of the sewing machine is a hand mode or a sewing mode. CONSTITUTION:When the sewing machine is actuated by a start/stop key 5, each driving motor is reset to an initial set state, and thereafter, sewing is executed by controlling each driving motor. In such a state, when the sewing machine stops due to an operation of the start/stop key 5, and a lock of the sewing machine caused by thread entanglement, etc., a hand mode of a hook is selected by a worker. A hand mode switch 29 becomes a turn-on state, and hand turning of the hook is executed. In such a state, when an actuating instruction of the sewing machine is generated by the start/stop key 5, a warning is raised by a warning generating means. Subsequently, the sewing mode is selected by the worker and when the hand mode switch 29 is turned off, the sewing machine can be actuated again.
