A compressed air supplying device of a sewing machine includes an air pump unit including a piston; a piston driving spring applying biasing force to the piston in an exhaust air direction which is a direction in which the air pump unit exhausts air for driving the piston in the exhaust air direction by the biasing force; a lever making the air pump unit perform intake air movements; and an operating force transmitting mechanism transmitting operating force of the lever to the piston for actuating the piston only in an intake air direction which is a direction in which the air pump unit intakes air against the biasing force of the piston driving spring by the operating force.

A sewing machine includes a sewing portion, a processor, and a memory. The sewing portion is configured to sew a pattern on a sewing object. The memory storing computer-readable instructions that, when executed by the processor, perform the processes. The processes include the acquiring reference data representing a relative positional relationship between a sewing position and an arrangement position. The sewing position is a position of the pattern sewn on the sewing object by the sewing portion. The arrangement position is a position of a decorative component arranged on the sewing object. The processes include displaying, on the basis of the acquired reference data, a mark that indicates the arrangement position corresponding to the sewing position.

An editing apparatus displays an editing screen for editing data for a medium to be processed by processing equipment including a printer, a cutting machine, and a sewing machine on a display. The data includes print data to drive the printer, cutting data to drive the cutting machine, and sewing data to drive the sewing machine. The editing apparatus receives an operation for editing the data with the editing screen or the preview screen displayed on the display, edits the data in accordance with the operation received, and outputs the data edited to the printer, the cutting machine, and the sewing machine.

The present invention relates to a sewing machine, specifically a long-armed stitcher. The present invention includes a computer device that may store pantograph patterns therein. The data including the pantograph patterns may be sent to projection units associated with the sewing machine head of the long-armed stitcher. The projection units use projection elements to project the pantograph patterns on the fabric to be stitched, allowing an operator of the stitcher to trace the projected pattern with a needle associated with the sewing machine head. Measurement devices associated with the sewing machine head determine head movement and alter the projected pattern accordingly such that the needle of the sewing head may continue to follow the pantograph pattern despite the head having moved in order to trace the pattern.

A cover material for a vehicle seat sheet is provided. The cover material for a vehicle seat sheet includes a first fabric, a second fabric, and a decorative piping member. The decorative piping member includes an approximately rectangular seam margin part, a tubular part connected to a widthwise end part of the seam margin part, and a core part arranged in the tubular part in an inserted state. The decorative piping member includes a warp and a weft that both form the tubular part and the seam margin part, and an insertion thread that forms the core part. These are integrally woven with a loom. The seam margin part of the decorative piping member is sandwiched by and between an end part of the first fabric and an end part of the second fabric, and these parts are sewed together in a mutually overlapped state.
