Abstract
In a thread standing device capable of switching a plurality of spool pins between a stored state and a deployed state and a sewing machine having the thread standing device, an operability is improved during the switching operation. In a thread standing device, a plurality of spool pins can be switched between a stored state and a deployed state, operation portions related to a switching operation of the plurality of spool pins is provided, and the plurality of spool pins are configured to be switched from the stored state to the deployed state when the operation portions are operated.
Claims4
A thread standing device of a sewing machine capable of switching a plurality of spool pins between a stored state and a deployed state, the thread standing device comprising:
- an operation portion configured to be moved for switching the plurality of spool pins;
- a base which swingably supports the plurality of spool pins;
- a plurality of sliders which is slidably supported by the base;
- and
- an elastic body which energizes the plurality of spool pins in a direction of switching from the stored state to the deployed state, wherein
- each of the plurality of sliders includes a stopper configured to keep each of the spool pins in the stored state,
- each of the plurality of spool pins includes a stored locking portion configured to be engaged with the stopper in the stored state,
- when the operation portion is moved, the stopper is slid from a state of being engaged with the stored locking portion to a state being separated from the stored locking portion for switching all of the plurality of spool pins from the stored state to the deployed state by an energizing force of the elastic body.
