摘要:
An embroidery unit including a first switch mechanism rotating a Y-direction drive mechanism driving a carriage having a detachable embroidery frame holding a workpiece cloth connected thereto from the embroidery position to the upright position taking a vertical disposition, a second switch mechanism switching the Y-direction drive mechanism from the upright position to the stored position situated along a side surface of the unit body 31. Further, the upper surface of the exterior cover of the Y-direction cover and the upper surface of the bed are arranged to be substantially at level when the Y-direction drive mechanism is switched to the stored position.

A needle bar thread guide for a sewing machine includes a thread guide body mounted on a needle bar and having a threading portion for threading the sewing machine, an introducing portion formed on the thread guide body for introducing a needle thread to the threading portion, and a fall-off preventing member disposed at a position near to spaces over and below the thread guide body. The fall-off preventing member allows the needle thread to be introduced via the introducing portion to the threading portion and prevents the needle thread introduced to the threading portion from falling off from the introducing portion.

An embroidery frame includes an outer subframe with a section that breaks continuity, an inner subframe that is snapped inside of the outer subframe to hold a cloth with the outer subframe, a clamp mechanism for clamping the outer subframe against the inner subframe. The clamp mechanism includes a pair of screw attachment sections facing each other at both ends of the continuity-breaking section of the outer frame, an adjustment screw attached across the screw attachment sections for adjusting a space between the screw attachment sections, an operation shaft for rotating the adjustment screw that moves in a range from a first position at which the operation shaft is directed in an axial direction same as or different from the adjustment screw, and a second position at which the operation shaft is tilted in a direction increasing a space with the outer subframe, and a coupling mechanism for coupling together the operation shaft and the adjustment screw, and transferring a torque of the operation shaft to the adjustment screw.

A pattern selection apparatus displays patterns and allows any of the displayed patterns to be directly selected. The apparatus comprises a control circuit, a display unit, an item designating dial and a selection establishing key. The control circuit indicates on the display unit where a cursor-highlighted displayed pattern is located relative to all the patterns under the same subset heading. As the cursor is moved in response to rotation of the item designating dial, the pattern location indication is correspondingly changed. Pushing the selection establishing key selects the cursor-highlighted pattern. Thus, any of the patterns displayed on the display unit is selected quickly and easily.

An attachment structure for detachably attaching a workpiece holder to a movable body used in embroidery stitching in a sewing machine. The movable body is movable in a horizontal plane in synchronism with a reciprocating motion of a sewing needle in order to move the workpiece relative to the needle. The workpiece is supported on the workpiece holder held by the movable body. The attachment structure includes pair of pins disposed at one of the workpiece holder and the movable body, pair of engaging grooves engageable with the pins and formed at remaining one of the movable body and the workpiece holder, projecting body disposed at one of the workpiece holder and the movable body, and resilient member engageable with the projecting body and disposed at remaining one of the movable body and the workpiece holder.

A semiconductor memory device containing a number of memory cells each having a floating gate, an erase gate, and a control gate. In a data erasure mode, electrons are discharged from the floating gate into the erase gate electrode. An insulating film interlaid between the erase gate and the control gate has a three-layered structure consisting of a silicon oxide film, a silicon nitride film, and a silicon oxide film.
