A sewing apparatus for applying a stitch of thread to a piece of fabric is provided. The apparatus housing includes a platform for supporting a piece of fabric, and contains a grasping member that is moved to grasp and release a thread segment fed through the housing by a needle holder. The needle holder is positioned to hold a needle that has a needle aperture for pass-through, therethrough of the thread segment, and is movable between a withdrawn position, and an advanced position in which the needle holder drives the needle through the piece of fabric to bring the thread segment into position for grasping by the grasping member. The sewing apparatus also including a needle holder driver for driving the movement of the needle holder and a thread puller for pulling the thread segment to an exterior of the housing for a user to cut.

A multi-needle sewing machine includes a plurality of needle bars, a needle plate, a needle bar case, a needle bar drive mechanism, a needle bar case movement mechanism, a mounting portion, a frame movement mechanism, a processor, and a memory. The memory is configured to store computer-readable instructions that, when executed by the processor, instruct the processor to perform processes. The processes include identification processing of identifying a position of the needle bar case in the arrangement direction, in accordance with detection of a retraction command causing the mounting portion to be moved to a retracted position, setting processing of setting the retracted position of the mounting portion on the basis of the identified position of the needle bar case in the arrangement direction, and movement processing of controlling the frame movement mechanism to move the mounting portion to the set retracted position.

A sewing machine includes a bed portion, a conveyance portion, a sewing portion, an image capture portion, a projector, a processor, and a memory. The conveyance portion is configured to convey a sewing object placed on the bed portion. The memory is configured to store marker information and computer-readable instructions that, when executed by the processor, instruct the processor to perform processes. The processes include causing the image capture portion to perform the image capture at a predetermined timing, during a conveyance period, identifying the marker in a captured image, using the marker information stored in the memory, identifying a projection position corresponding to the identified marker, when the marker is identified, and causing the projector to project the projection image indicating the identified projection position, while following a movement of the marker on the sewing object being conveyed.

A position indicating circuit includes: first and second input terminals for respectively receiving first and second voltages; an output terminal; a first resistor; and a second resistor having a first terminal coupled to the first input terminal through the first resistor, a second terminal coupled to the second input terminal, and a third terminal coupled to the output terminal. The second resistor is used to be actuated by a pedal of a foot controller of a sewing machine such that a voltage at the output terminal has a magnitude related to a position of the pedal. A detecting system that uses the position indicating circuit and that can determine whether the foot controller is coupled to a main body of the sewing machine is also provided.
