[Claims for Utility Model Registration] 1. Two upper threads are passed through the clamping part of the first solenoid, are constantly pinched between the driving roller and the driven roller, and are sent through the clamping part of the second solenoid to the thread take-up. In the needle thread supply device, the needle thread feeder feeds the two needle threads by appropriate amounts by turning on and off the first and second solenoids. An upper thread supply device for a sewing machine, characterized in that the needle thread supply device for a sewing machine is provided with a means for separating a driven roller on a resting needle thread side from a driving roller. 2. Pass the two upper threads through the clamping part of the first solenoid and feed them while being constantly clamped between the driving roller and the driven roller, pass them through the clamping part of the second solenoid to the thread take-up, and send them through the clamping part of the second solenoid. In the needle thread feeding device, in which the two needle threads are fed by appropriate amounts by turning on and off a solenoid No. 2, when sewing with one of the two needle threads is stopped, the needle thread on the resting needle thread side is An upper thread supply device for a sewing machine, comprising means for operating a first solenoid at minute time intervals to sequentially feed the idle thread by minute lengths.
