Abstract: A sewing machine includes a needle, a holding frame having a stitchable area within which the needle is operable to perform stitching, storing means for storing sewing data on various embroidery patterns, indicating means for indicating, within the stitchable area, positions on the workpiece that is held by the holding frame, stitching region setting means for setting a stitching region in accordance with the positions indicated by the indicating means, embroidery pattern creating means for creating, in accordance with a position and a size of the stitching region, and based on the sewing data, embroidery pattern data on an embroidery pattern having a size that is fittable within the stitching region, and control means for controlling the needle and the holding frame to form the embroidery pattern on the workpiece within the stitching region in accordance with the embroidery pattern data.

Abstract: There are provided an upper shaft clutch mechanism 140, a bobbin 22 including a slit 39, a horizontal holder 4 including an inner holder 18 and a blade tip 42, a bobbin driving member 11, bobbin driving member moving means 94 for moving the bobbin driving member 11 to freely advance or retreat between two positions having a separating position and a connecting position, a thread holding and catching member 48 including an upper thread holding portion 59, an upper thread engaging portion 60 and a thread position regulating portion 58 which are always set in a retreat position and are set in an entry position during a thread winding operation, thread holding and catching member moving means 53 for moving the thread holding and catching member 48 to freely advance or retreat between two positions having a retreat position and an entry position, and a thread winding operation control portion 193 for controlling the operation of each portion during the thread winding operation.

Abstract: In an embroidery sewing machine having a lower thread winding device, when the non-lower thread state of the bobbin is detected by a residual amount sensor, a sewing machine motor is stopped to detect and recognize the size of the embroidering frame of an embroidering device by means of a frame size sensor and the embroidering frame is moved corresponding to the size to position the corner of a workpiece held in the embroidering frame under a needle. Then, an extra sewing operation is carried out over the corner to consume the lower thread remaining in the bobbin, and subsequently, it is decided whether or not the embroidering frame is moved by a distance required for completely extracting the lower thread from the bobbin (an amount of the residual lower thread is detected when the non-thread state is detected by the residual amount sensor).

Abstract: A color marking apparatus for marking designated areas of an original with a designated color by recording the whole area of an original with a first color, such as black. Desired areas on the original are designated, and the designated areas are colored with a second color different from the first color, and the second color is recorded with a copy density different from the copy density used to record the first color. The color marking apparatus is controlled such that the recording operations of the apparatus are carried out in a selected order.

Abstract: A memory stores values representing distances from a predetermined reference position to positions corresponding to a plurality of selectable reduction/magnification factors. Upon the selection of a desired reduction/magnification factor, the current and desired positional values, both referenced to the predetermined reference position, are compared to obtain a signal representing the distance and direction which the optical system must be moved.
