Abstract
Abstract A sewing machine-pattern data processor including a coordinate input device for outputting coordinate positions on a plane by means of a manually operable stylus; an arithmetic and logic unit which receives the sewing machine pattern data input from the coordinate input device to convert the data to command data for a predetermined sewing machine unit control operation; a memory for memorizing the command data converted by the arithmetic and logic unit; and a write-in device which reads out the data of the memory to write-in a non-volatile recording medium.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
157 words
A sewing machine-pattern data processor for producing pattern data adaptable for controlling operation of an automatic sewing machine, comprising: a co-ordinate input device separate from said sewing machine, comprising an input plane defining plural co-ordinate positions, a manually operable stylus for selecting selected of said co-ordinate positions corresponding to a sewing pattern and means for forming sewing machine pattern data based on the selected co-ordinate positions; an arithmetic and logic unit which receives the sewing machine pattern data input from the co-ordinate input device and converts the data to command data for a predetermined sewing machine unit control operation; a memory for memorizing the command data converted by the arithmetic and logic unit; a write-in device which reads out the data of the memory and writes the data in a non-volatile recording medium; a pattern output device which outputs a command data memorized in the memory and includes a CRT display for displaying the sewing machine pattern.
Claim 2
Dependent Claim
157 words
A sewing machine-pattern data processor for producing pattern data adaptable for controlling operation of an automatic sewing machine, comprising: a co-ordinate input device separate from said sewing machine, comprising an input plane defining plural co-ordinate positions, a manually operable stylus for selecting selected of said co-ordinate positions corresponding to a sewing pattern and means for forming sewing machine pattern data based on the selected co-ordinate positions; an arithmetic and logic unit which receives the sewing machine pattern data input from the co-ordinate input device and converts the data to command data for a predetermined sewing machine unit control operation; a memory for memorizing the command data converted by the arithmetic and logic unit; a write-in device which reads out the data of the memory and writes the data in a non-volatile recording medium; a pattern output device which outputs a command data memorized in the memory and includes a CRT display for displaying the sewing machine pattern.
Claim 3
Dependent Claim
94 words
The pattern data processor according to claim 1 wherein: the input plane of said co-ordinate input device comprises a function input part divided into sections corresponding to an operating function of said co-ordinate input device and sections corresponding to control functions for controlling the sewing machine, and a pattern input part for inputting sewing patterns of the sewing machine; and said co-ordinate input device includes means for setting all operation functions, control functions, and the sewing machine pattern data by the operation of the stylus from the input plane of the co-ordinate input device.
Claim 4
Dependent Claim
30 words
The pattern data processing according to claim 2 which comprises an operation and control display for displaying the operation and control functions for the input of the sewing machine pattern.
Claim 5
Dependent Claim
72 words
The pattern data processor according to claim 1 which comprises at least one of the following means: (a) means for forming stitches by dividing a space between a designated two points into integer equal pitches substantially the same as a desired pitch; (b) means for forming stitches in said pitches on the continuous trace designated by the stylus; and (c) means for forming each stitch at each point designated by the stylus.
Claim 6
Dependent Claim
40 words
The pattern data processor according to claim 2 which comprises: means for processing the set operation and control functions and the sewing pattern data input from the coordinate input device to enlarge or contract a size of the sewing pattern.
Claim 7
Dependent Claim
25 words
The pattern data processor according to claim 3, which comprises: an operation display for displaying the operation orders for the input of the sewing pattern.
