A printer includes a first storage, a head, a first supply flow path, a first circulation flow path, a second supply flow path, and a second circulation flow path. The first storage is configured to be supplied with ink from a second storage, and is configured to store the supplied ink. The head configured to eject the ink. The first supply flow path merges with one of the second supply flow path and the second circulation flow path at one of a first connector and the first storage. The first circulation flow path merges with the other of the second supply flow path and the second circulation flow path at one of a second connector and the first storage.

Printer

An ink refilling device including a supply portion to be connected to an ink cartridge and supply ink, an ink tank, a first connecting tube having one end connected to the ink tank, a three-way switching valve including an input end connected to the other end of the first connecting tube, a first output end and a second output end, and adapted to switch between a first flow path from the input end to the first output end and a second flow path from the input end to the second output end, a second connecting tube having one end connected to the first output end and the other end connected to the supply portion, a third connecting tube having one end connected to the second output end and the other end connected to the ink tank, and a feed pump provided along the first connecting tube to feed the ink.

Ink refilling device

An inkjet head is provided. The inkjet head includes an ink reservoir to store ink, an ink inlet, through which the ink is introduced to the ink reservoir, an ink outlet, through which the ink in the ink reservoir is allowed to flow to the inkjet nozzle. The ink reservoir has a wall arising from a bottom of the ink reservoir to divide the ink reservoir into a plurality of ink chambers. The plurality of ink chambers include a first ink chamber and a second ink chamber. The plurality of ink chambers are in fluid communication with each other over a top edge of the wall. The wall is formed to include a through hole, which is formed in a vicinity of the bottom of the ink reservoir and allows the plurality of ink chambers to be in fluid communication with each other.

Inkjet head and printing apparatus

An apparatus for supplying, to a sewing device, a connected belt-loop material including at least one connection portion where two long materials are connected to each other, the connection portion having a width greater than a substantially constant width of a remaining portion of the belt-loop material, the apparatus including a feeding device which feeds the belt-loop material toward the sewing device, and a positioning device which positions, in a direction extending parallel to the width of the belt-loop material, at least the remaining portion of the belt-loop material being fed by the feeding device, so that the remaining portion takes a reference position in the direction of width, the positioning device including a permitting device which permits the connection portion of the belt-loop material to be fed through the positioning device by the feeding device, without lowering an accuracy with which the remaining portion of the belt-loop material is positioned by the positioning device in the direction extending parallel to the width.

Apparatus for supplying belt-loop material to sewing machine

A sewing system including a stitch-forming device including at least one sewing needle, for forming stitches on at least one workpiece; a feeding device which feeds at least one of the stitch-forming device and the workpiece relative to the other of the stitch-forming device and the workpiece along a reference plane; a control device which controls, according to at least one set of sewing data corresponding to at least one sewing pattern including a plurality of stitches, the stitch-forming device and the feeding device to form the stitches of the sewing pattern on the workpiece; a dimension-data memory which stores a plurality of sets of dimension data which correspond to a plurality of dimensions, respectively, each of which relates to the set of sewing data; and a selecting device which is operable for selecting one of the sets of dimension data stored in the dimension-data memory.

Electronically controlled sewing system

An oscillating shuttle, including a shuttle race having a substantially annular guide groove including two end portions opposed to each other in a circumferential direction thereof, a shuttle body which includes a part-annular guided portion and a hook portion and which is oscillatory while the guided portion is guided by the guide groove, a driver which rotates the shuttle body about an axis line, wherein when the hook portion hooks a thread loop, the shuttle body is rotated by the driver in one of opposite directions such that the tail portion passes through one of the two end portions of the guide groove and enters an upper opening of the shuttle race and, when the shuttle body is rotated back in the other direction, a tail portion of the guided portion enters the one end portion of the guide groove, and at least one of the one end portion of the guide groove which has, in a direction parallel to the axis line, a width greater than a width of a remaining portion of the guide groove, and the tail portion of the guided portion which has, in a direction parallel to the axis line, a width smaller than a width of a remaining portion of the guided portion.

Oscillating shuttle of sewing machine

A headgear holding apparatus for use with an embroidery sewing machine including a machine body having a sewing-bed arm, the apparatus including a base structure; a guiding device including a guide member, for guiding the base structure in a guiding direction; a rotatable structure supported by the base structure such that the rotatable structure is rotatable about an axis line parallel to the guiding direction; a headgear holder holding a headgear into which the sewing machine forms stitches, the headgear holder being detachably securable to the rotatable structure; and the guide member of the guiding device being detachably securable to the machine body of the sewing machine such that the guide member extends substantially parallel to the sewing-bed arm of the sewing machine.
