In FIG. 5, a main central processing unit (hereinafter referred to as CPU) 35 of the needle selection control device outputs a control signal to a card signal reading control circuit 36 to knit the knitting pattern P recorded on the card 8 by the reading mechanism. The pattern information reading operation is performed and the read knitting pattern information is input.
Then, the CPU 35 selects a predetermined knitting needle 4 based on this knitting pattern information and creates needle selection data for embodying the knitting pattern P1.

The needle selection data set memory 37 is a readable and rewritable memory (random access memory) in which the needle selection data is temporarily stored and sequentially read out in synchronization with the movement of the carriage 5. and is output to the solenoid control circuit 38.

It outputs a lighting control signal for turning on or off the PL 12, and also outputs a drive signal to the buzzer circuit 40 for making the buzzer 34 sound for 0.5 seconds.

Further, the CPU 35 selects the first or second scale 1 involved in forming the knitting pattern P1 based on the on/off signals from the keys KY1 to KY12 and the scale position data from the encoder circuit 39.
The knitting needle groups divided by sections B1 and B2 of 5 and 18 are identified, and the knitting pattern P is created using only the knitting needle groups based on the determined data and the knitting pattern information.
1 is designed to form needle selection data to be realized.

Next, the operation of the knitting machine configured as described above will be explained.

First, the card 8 is inserted into the card insertion portion 9, and the feed dial 32 is operated to set it at the starting position as shown in FIG. Next, turn on the power switch 3
When 3 is turned on, the CPU 35 is initialized,
All the indicator lamps PL1 to PL12 are turned off and the needle selection data set memory 37 is cleared once.

Now, a knitting pattern P1 based on the knitting pattern P recorded on the card 8 is created, as shown in FIG.
Then, operate the dial 23 to make two on the left side and one on the right side. Then, the index 24 displayed on the display window 25 of the dial 23 is "θ", that is, the center position of section B1 of block number 5 on the first scale 15 is the number 1 left knitting needle 4 and the number 1 right knitting needle 4. Operate so that it is in the middle position. Then, the worker is on the first scale 15
By looking at each section B1 and each knitting needle 4, it is confirmed which section B1 the knitting needles 4 are divided into and what kind of knitting needle group block they constitute.

On the other hand, the CPU 35 inputs the scale position data at this time from the encoder circuit 39, and based on this scale position data, the CPU 35 determines which section B1 each knitting needle 4 is assigned to.
In other words, each knitting needle group classified into each section B1 is calculated and stored in a register within the CPU 35.

Next, key operations are performed to determine which knitting needle group among the divided knitting needle groups is used to embody the knitting pattern P1 based on the knitting pattern P. Now, as shown in Figure 6, block number "3"
When the point keys KY3 to KY6 corresponding to the block number are turned on in order to realize the knitting pattern P1 with each knitting needle group divided into the block B1 of ~ "6", the CPU 35 , lights up the corresponding indicator lamps PL3 to PL6, and lights up the block numbers "3" to
After selecting the knitting needle group corresponding to section B1 of "6",
Sound the buzzer 34 for 0.5 seconds.

Next, the key operation is performed to determine whether or not to change the knitting pattern P1 realized by each selected knitting needle group.

As shown in Fig. 6, if the knitting pattern P1 based on the knitting pattern P is to be directly realized, the key
If you want to realize the knitting pattern P1 with the knitting pattern P reversed left and right as shown in Fig. 7a, without operating KY10 to KY12, press the key.
If you want to embody the knitting pattern P1 with the knitting patterns P facing each other as shown in Fig. 7b, press the key KY12, or press the key KY11 so that the knitting patterns P face each other as shown in Fig. 7c. If it is desired to embody knitting pattern P1, it is possible by selecting keys KY11 and KY12, respectively. Furthermore, as shown in FIG. 7d, if you want to realize knitting pattern P1 by enlarging knitting pattern P twice in the horizontal direction, that is, by using two groups of knitting needles divided by section B1, press key KY1. The knitting pattern P is enlarged to twice that size.
If you want to realize the image in the opposite direction to the left and right as shown in FIG. 7e, you can do so by selecting the keys KY10 and KY12.

Note that when key KY10 is selected, the indicator lamp PL
In the horizontal double mode where 10 is lit, the indicator lamps of each pair of point blocks are controlled so that they are lit at the same time.For example, the indicator lamp PL3 of block number "3" is lit. When key KY10 is selected, indicator lamp PL4 of block number "4", which is paired with block number "3", is also lit. Also, at the beginning, the key KY10 for horizontal doubling is selected and the instruction lamp
If PL10 is lit, then, for example, by selecting key KY5 of one block number "5", the two indicator lamps PL5 and PL
6 are lit at the same time and block numbers ``5'' and ``6'' are displayed.
It is displayed that a horizontally doubled knitting pattern is realized on the group of knitting needles.

Now, when the key KY12 is turned on to embody the knitting pattern P1 shown in FIG. 7a, the CPU 35
is the corresponding indicator lamp based on this on signal
After turning on the PL 12 and setting the knitting pattern P1 based on the knitting pattern P in opposite left and right directions, the buzzer 34 is sounded for 0.5 seconds.

When the key operation is completed, the carriage 5 is slid and knitting work is started. At this time, the CPU 35 operates the reading mechanism via the card signal reading control circuit 36 in connection with the reversal of the carriage 5, controls the sequential stage feeding of the card 8, and sets the reading sensor to the knitting pattern P on the card 8. The knitting pattern information, which is a read signal, is read from the sensor. Then, the CPU 35 performs calculations for changing the knitting pattern P1 based on this knitting pattern information, the scale position data, and the keys KY10 to KY12, and further based on the ON operation of point keys KY3 to KY6. Needle selection data corresponding to each pattern row is created so that the knitting pattern is realized only on the knitting needle group of the selected category, and is temporarily stored in the needle selection data set memory 37, and as the carriage 5 travels. The needle selection data is output to the solenoid control circuit 38, and the needle selection solenoid 7 is excited and controlled by the same circuit 38.

Therefore, each time the carriage 5 is turned back and travels in the left and right direction, the knitting pattern information of each pattern row in the knitting pattern P on the card 8 is read.
The knitting pattern P1 shown in FIG. 7a is realized in opposite directions by only the selected knitting needle groups.

Similarly, if you want to realize knitting patterns P1 as shown in FIGS.
is obtained, but especially when horizontal multiplication is specified,
Among the knitting needle groups divided by section B2 of the second scale 18, the CPU 35 selects the knitting needle group belonging to section B2 consisting of blocks "3" and "4" involved in realizing the knitting pattern P1 and the block number " A group of knitting needles belonging to section B2 consisting of "5" and "6" is selected. Based on this selection, the CPU 35 is
Needle selection data for embodying the knitting pattern P1 as shown in e is created. Then, when the carriage 5 is slid, the needle selection solenoid 7 is excited and controlled in the same manner, and the horizontal double knitting pattern P1 is realized.

In addition, when it is desired to change the position where the knitting pattern P1 is formed, in other words, the knitting pattern P1 shown in FIG.
If you want to shift the dial 23 to the left, for example, by 6 points, turn the dial 23 to the left and move the indicator 24.
It should be set so that the value is "6". At this time
Based on the movement of the first scale 15 and the scale position data from the encoder circuit 39, the CPU 35 is divided into sections B1 of block numbers "3" to "6" at positions shifted to the left by the sixth scale. Index and select a group of knitting needles. Then, based on this selection, the CPU 35 creates needle selection data in which the 6th stitch is shifted to the left in the same manner as described above, and controls the excitation of the needle selection solenoid 8 based on the data, so that the data shown in FIG. 7b is obtained. The knitting pattern P1 shown is realized at a position shifted six stitches to the left.

In this way, in this embodiment, when the knitting pattern P1 based on the knitting pattern P recorded on the card 8 is to be realized at a predetermined position, the first or second scales 15, 18 are moved and Scales 15 and 18 are placed on the knitting needle group that embodies the knitting pattern P1 at the position.
By combining the sections B1 and B2, the section B
It is only necessary to turn on the point keys KY1 to KY9 for 1 and B2, and the position where the knitting pattern P1 is to be realized can be set with a very simple operation and in an easy-to-understand manner. Moreover, the operator must use the first or second scale 15, 18 and the indicator lamps PL1 to PL1.
Just by looking at PL9, the position where the knitting pattern P1 is realized can be easily confirmed. Therefore, according to this embodiment, when embodying the knitting pattern P1, the knitting pattern P1 is not restricted to the above-mentioned classification for each block, but can be freely selected as long as it is within the movement range of the belt 12, which is selectable by the dial 23. The knitting pattern P1 can be realized at the position.

In addition, in Figure 3, all point keys KY
1 to KY9 are selected and all of the point indicator lamps PL1 to PL9 light up, needle selection data is created that embodies a repeated knitting pattern across all the needles 4 on the needle bed, and the so-called The knitted fabric of the entire pattern is knitted.

In addition, in this embodiment, since the belt 12 can move by 48 pitches in the direction in which the knitting needles are arranged on the needle bed, the CPU 35 uses the key KY1 for horizontal doubling.
When the key KY11 for facing and the key KY11 for facing are selected at the same time, only facing is made to function effectively, and only the instruction lamp PL11 is lit.
However, if the amount of movement of the belt 12 is expanded to, for example, 96 pitches, it is possible to freely realize a knitting pattern in which horizontal folding and facing function simultaneously, and the position of the realization can be arbitrarily selected. and can be set.

Note that the present invention is not limited to the above-described embodiment; for example, the dial 23 serving as the first selection means may be replaced with a key switch, and the pulse motor may be rotated in forward and reverse directions under the control of the CPU 35 based on the operation of the key switch. Alternatively, the first or second scales 15, 18 on the belt 12 may be moved, or the moving position of the scale may be detected directly from the rotary encoder instead of using a rotary switch and an encoder circuit. In addition, all knitting pattern information for knitting pattern P is already stored in read-only memory (ROM).
Alternatively, the information may be stored in a random access memory (RAM) and applied to a knitting machine that performs knitting to realize a knitting pattern based on the stored information.

Effects As described in detail above, the present invention moves a movable member provided with an identification mark for appropriately dividing a group of knitting needles into several blocks by the first selection means, and performs classification based on the identification mark at the moving position. An arbitrary knitting needle group is selected by the second selection means from among the selected knitting needle groups, and the knitting pattern is realized only on the selected knitting needle group. Even when the knitting pattern is realized, it is possible to reliably embody the same knitting pattern as originally set, and it is possible to set the embodying position of the knitting pattern with a very simple operation and in an easy-to-understand manner. A movable member whose position can be easily confirmed is moved by the first selection means, and an arbitrary knitting needle group is selected by the second selection means from among the divided knitting needle groups based on the identification display at the moved position. Since the knitting pattern is realized only on the group of knitting needles in the selected category, the position where the knitting pattern will be realized can be set with a very simple operation and in an easy-to-understand manner, and the position where the knitting pattern will be realized can be set. has an effect that can be easily confirmed.
