Abstract
Abstract An embroidering machine is provided with a display section which is retractable within a machine housing and can be pulled to an operational position when in use for select/input operation. Several kinds of select/input operation can be made with a single display means, by suitably changing and selecting the display mode. Select/input operation is made by plotting an appropriate portion seen in the display, reducing to a great extent erroneous operation with a visual support.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
252 words
In an embroidering machine having a machine housing, a vertically reciprocated needle supported by the machine housing and carrying a thread, a thread loop-taker cooperating with the needle to form a stitch on a fabric, an embroidery frame for supporting the fabric, means for shifting the embroidery frame with respect to the needle, and memory means for storing embroidery stitch control data for a plurality of patterns including character patterns, the data being selectively and sequentially read out from the memory means to drive the frame shifting means to thereby produce stitches of a selected pattern, the improvement which further comprises; camera means mounted on the machine housing in opposition to said embroidery frame for taking a picture of the fabric stretched between said embroidery frame, said picture representing the positional relationship between the fabric and the needle; a graphic display connected to the machine housing, said graphic display being operatable in a first operation mode to display a list of stitchable patterns, and alternatively said graphic display being operatable in a second operation mode to display the picture taken by said camera means; and signal generating means cooperating with said graphic display so that one or more of desired characters shown on said display can be selected when said graphic display is in said first operation mode, and specific points on the graphic display of the fabric stretched on the embroidery frame to be stitched can be designated to define boundaries of the actual stitching when in said second operation mode.

In an embroidering machine having a machine housing, a vertically reciprocated needle supported by the machine housing and carrying a thread, a thread loop-taker cooperating with the needle to form a stitch on a fabric, an embroidery frame for supporting the fabric, means for shifting the embroidery frame with respect to the needle, and memory means for storing embroidery stitch control data for a plurality of patterns including character patterns, the data being selectively and sequentially read out from the memory means to drive the frame shifting means to thereby produce stitches of a selected pattern, the improvement which further comprises; camera means mounted on the machine housing in opposition to said embroidery frame for taking a picture of the fabric stretched between said embroidery frame, said picture representing the positional relationship between the fabric and the needle; a graphic display connected to the machine housing, said graphic display being operatable in a first operation mode to display a list of stitchable patterns, and alternatively said graphic display being operatable in a second operation mode to display the picture taken by said camera means; and signal generating means cooperating with said graphic display so that one or more of desired characters shown on said display can be selected when said graphic display is in said first operation mode, and specific points on the graphic display of the fabric stretched on the embroidery frame to be stitched can be designated to define boundaries of the actual stitching when in said second operation mode.
Claim 3
Dependent Claim
17 words
The embroidering machine according to claim 1 wherein said graphic display is retractable within the machine housing.
Claim 4
Dependent Claim
249 words
In an embroidering machine having a machine housing, a vertically reciprocated needle supported by the machine housing and carrying a thread, a thread loop-taker cooperating with the needle to form a stitch on a fabric, an embroidery frame for supporting the fabric, means for shifting the embroidery frame with respect to the needle, and memory means for storing embroidery stitch control data for a plurality of patterns including character patterns, the data being selectively and sequentially read out from the memory means to drive the frame shifting means to thereby produce stitches of a selected pattern, the improvement which further comprises; an image input frame having a configuration corresponding to the embroidery frame and replaceable therewith, but designed to carry a picture desired to be embroidered on the fabric in the embroidery frame; camera means mounted on the machine housing in opposition to said image input frame attached to the machine housing for taking a photograph of the picture, said photograph representing relative position data between the picture and the needle; a graphic display connected to the machine housing, for displaying thereon said relative position data between the picture and the needle and capable of reproducing a picture on the image input frame; and signal generating means cooperating with said graphic display so that sufficient stitch boundary points to define curvature and bounds of the stitching for reproducing the picture on the fabric can be defined in terms of the coordinates of the display and therefore the embroidery frame.
Claim 5
Dependent Claim
