| 112273000 | Thread sensing | 1 |
| 20130087086 | Bobbin thread monitor - A bobbin thread monitor includes a rotatable thread pulley together with a rotation sensing counter and numeric count display. During bobbin loading, the thread supply is looped about the pulley in a first direction resulting in rotation of the thread pulley in a corresponding first direction. The rotation of the thread pulley in the first direction produces an accumulated account within the rotation sensing and display apparatus. During sewing operations, the thread supply is looped about the thread pulley in a second opposite direction loop resulting in opposite direction rotation of the thread pulley during the sewing process. The opposite direction rotation of the thread pulley during the sewing process produces a downcount of the number accumulated during the bobbin loading process. This down count is indicative of bobbin supply remaining and may be used to activate additional alarm apparatus. | 04-11-2013 |

| 20090056608 | SEWING MACHINE - A sewing machine is provided. The sewing machine includes a top covering shaft mechanism, a spreader mechanism detachably attached to the top covering shaft mechanism from below and operable to catch a covering thread and to interlace the covering thread with a needle thread inserted into a needle to form covering stitches, and an operating member having a hook portion and rotatably attached to either one of the top covering shaft mechanism and the spreader mechanism. The other of the top covering shaft mechanism and the spreader mechanism has a protrusion with which the hook portion is engageable. The operating member is rotatable between a position at which the hook portion engages with the protrusion to lock the spreader mechanism with respect to the top covering shaft mechanism and another position at which the spreader mechanism is detachable from the top covering shaft mechanism. | 03-05-2009 |
| 20090235855 | Sewing machine and computer-readable medium storing control program executable in sewing machine - A sewing machine that operates with power supplied from a main power supply includes a needle plate having a needle hole through which a sewing needle can pass, an illuminating device that illuminates the needle hole and a vicinity of the needle hole, a power supply device that stores power, a detection device that detects whether a predetermined operation is performed in the sewing machine, a power distribution device that supplies the power from the power supply device to the detection device and the illuminating device, if supply of the power from the main power supply is turned off, and a turning-on device that turns on the illuminating device, if the detection device detects that the predetermined operation is performed in a condition where the supply of the power from the main power supply is cut off. | 09-24-2009 |
| 20120060733 | SEWING MACHINE OPERATING DEVICE AND SEWING MACHINE PROVIDED THEREWITH - A sewing machine operating device includes a base, a connecting mechanism which electrically connects the sewing machine operating device to a sewing machine body, a plurality of operating members which is mounted on the base and operated by a user with his/her foot, a signal output unit which generates an operation signal and delivers the operation signal via the connecting mechanism to the sewing machine body, the operation signal being according to operation of each operating member, and a position adjusting mechanism which changes a position of at least one of the operating members mounted on the base. | 03-15-2012 |
| 20120060734 | SEWING MACHINE OPERATING DEVICE AND SEWING MACHINE PROVIDED THEREWITH - A sewing machine operating device includes a connection unit which is connectable to a sewing machine body, an output unit which generates and delivers an operation signal according to an action of user's foot, a placement pedestal on which user's foot is placed, a support unit which supports the placement pedestal so that the placement pedestal is movable in any direction, and a detection unit which detects that the placement pedestal or user's foot occupies any one of different predetermined positions when the user has moved the placement pedestal with user's foot being placed on the placement pedestal. | 03-15-2012 |
