Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for giving instructions for increasing or decreasing stitches for a predetermined molding pattern when knitting with a hand knitting machine, and in particular for displaying left and right stitches for each row of knitting, and for displaying the left and right stitches for each row of knitting, and This invention relates to a device that displays numerically the number of increases and decreases in stitches.

When performing conventional forming on a home hand knitting machine, first knit the gauge, measure the stitch number gauge and the number of row gauges, and then
The number of stitches for the number of knitting rows was obtained by calculating the pattern drawn on the paper pattern and using a knit tracer.

The present invention is characterized in that knitted fabrics are relatively stretchable and require relatively rough finishing accuracy, and that, for example, the number of stitches and rows between the parts of the front body to be joined must be approximately equal; Focusing on the fact that the number gauge and number of rows gauge cannot be measured accurately without considerable skill, for example, the number of stitches for the number of knitting rows of a pattern knitted with medium-thin yarn with dial 5 is stored in advance in an electronic storage device. As the user progresses through the knitting stages, the memorized contents are displayed in an easy-to-understand manner on a numeric display tube, etc., thereby making it easier for the user to perform tedious operations such as gauge knitting, preparing patterns, and determining the number of stitches. The purpose is to easily obtain molding information.

In addition, in the present invention, information on increases and decreases is automatically transmitted.
The purpose of this invention is to provide an easy-to-understand display of the number of each item, thereby making it easier for the user to make a decision.

Next, as shown in FIG. 3, when knitting the left shoulder part (the part marked with a dotted line) in the figure, the count value of the up/down counter 113 is returned to 181 and the count value of the number display device 121 is knitted.
123, 125, and 127 are set to 181, and the switch 128a is set to G2 (at the same time, the switch 128b is set.

128c is in the opposite state to that in FIG. 1) Since the up/down counter 113 is outputting 181, ROMI 1
8 outputs G7 as shown in the table above in response to the address input of 181, and since the switch 128a is set to G2, the bit representing the number is output to the inverting circuit 13.
The number is reversed at 8, the left lamp 141 lights up, and the number display devices 147 and 149 display 7.

On the other hand, the ROM 119 outputs 058 in response to the address input 181 as shown in the table, and the switch 128a outputs G2.
Since the bit is set to , the inverting bit is inverted by the inverting circuit 139, and the left lamp 140 lights up.
The number display devices 143 and 145 display 58.

The user sets the left end of the narrow cloth on the 58th knitting needle to the left of the standard knitting needle, and sets the right end of the narrow cloth on the 7 knitting needles to the left of the standard knitting needle.

Knit the left shoulder section in this way.

Thereafter, the read addresses of the ROMs 118 and 119 are advanced in the same manner, and the back sleeves and the like shown in the pattern chart 201 can be molded.

Similarly, the ROMs 118 and 119 have data on stitches corresponding to each knitting pattern recorded in advance, and using the pattern diagram 201 as a clue, the address in the column of the number of ROM stages can be read on the display devices 121, 123, 125, and 127. By confirming and setting the number on the numerical display, the required number of stitches can be easily recognized, for example, when re-knitting a half-stitch progression.

In addition, in the present invention, the stitch number data for each assembly given corresponding to each pattern diagram is a fixed set, and in order to adjust the finished size of the molded product, it is necessary to adjust the thread thickness. This is done by selection and adjustment of the stitch dial.

As shown on paper, when knitting according to the present invention, by setting the stage number display to the desired stage of the ROM read address at the beginning of use, from then on, each time the carriage moves one stage, the next stage is successively displayed. Since the left and right end stitches are displayed, and the number of increase/decrease of stitches in each row relative to the previous row is also displayed, it is convenient to accurately and easily judge the increase/decrease of stitches in each row in knitting work.

In this case, the cumbersome operation of checking patterns using a knit tracer, etc. is no longer necessary, and there is no need to install a pattern interlocking mechanism on the knitting machine itself, making the entire knitting machine more compact and reducing the operating force of the carriage. shall be taken as a thing.
