However, the present invention can be realized in various forms, and is not limited to the embodiments described herein.

Hereinafter, the structure and operation of the embodiment of the present invention will be described with reference to the drawings.
Referring to fig. 1 to 6, the multi-signal actuator 100 of the present invention includes a stationary shaft 10, a working plate 20, and an electromagnet 30.
The fixed shaft 10 extends in a longitudinal direction, has a cylindrical shape, and is fixed to a frame or the like.
The plurality of working pieces 20 are coupled to the fixed shaft 10 at predetermined intervals.
The working pieces 20 are formed of a thin plate, and a spacer ring 40 is provided between the working pieces 20.
That is, the plurality of work pieces 20 may be provided in a narrow space by forming them as thin plates.
Further, an operating portion 21 is formed at one end of the operating piece 20 and a signal detecting portion 22 is formed at the other end thereof, with the fixed shaft 10 as a center.
The signal detection unit 22 is formed of a pair of permanent magnets 22a, and has opposite polarities on both sides. That is, one is the N-pole permanent magnet 22aa, and the other is the S-pole permanent magnet 22 ab.
Further, it is preferable that the signal detection unit 22 is disposed to be shifted from the adjacent signal detection unit 22 by an angle to form a circular shape so as not to interfere with the fixed shaft 10 when coupled thereto.
In the relation with the operating portion 21, the signal detecting portion 22 can be formed at a desired angle, and for example, the rod 20 having each shape can secure a space angle so as to be perpendicular to the fixed shaft 10 within a range of a circular inner angle, so that a plurality of electromagnets 30 can be installed in a narrow space.
The electromagnet 30 angularly moves the work piece 20 at a predetermined angle, and a plurality of electromagnets are provided corresponding to the work piece 20.
The electromagnet 30 is configured by inserting an iron core 33 into a core 32 of the wound coil 31, and the iron core 33 is made of a magnetic material that generates a magnetic force smaller than a magnetic force generated by a magnet that generates a power supply by supplying power to the electromagnet.
Therefore, when the power supply to the electromagnet is interrupted at ordinary times, the magnetic force of the electromagnet disappears, and at the same time, an N-pole is generated at the tip of the core 33 made of a magnetic material, so that the S-pole permanent magnet 22ab formed in the signal detection unit 22 is pulled and the N-pole permanent magnet 22aa is pushed, so that the operating unit 21 of the operating piece 20 is spaced from the lever 50 around the fixed shaft 10, and conversely, when a current is supplied to the coil 31, the generated magnetic force generates an S-pole, and even if the tip of the core 33 made of a magnetic material has an N-pole, the S-pole is stronger, so that the attractive force of the N-pole permanent magnet 22aa of the signal detection unit 22 acts on the electromagnet, and the operating unit 21 of the operating piece 20 transmits a signal to the lever 50.
On the other hand, unexplained reference numeral 50 denotes a lever operated by an operating portion of the operating piece.
In the multi-signal actuator 100 of the present invention having the above-described structure, the operation pieces 20 are arranged on the fixed shaft 10 at predetermined intervals, the interval ring 40 is coupled between the operation pieces 20, the operation pieces 20 are formed of a thin plate, and a plurality of the operation pieces 20 can be installed in a narrow space.
The operating portion 21 formed at one end of the operating piece 20 is linear in the horizontal direction, and the signal detecting portion 22 is disposed to be angularly shifted from the adjacent signal detecting portion 22 around the fixed shaft 10 so as to correspond to the electromagnets 30, and a plurality of electromagnets 30 are provided so as to correspond to the signal detecting portion 22.
In this state, if a signal is not input to the electromagnet 30 corresponding to the signal detection unit 22 of the sequentially arranged blade 20 based on a signal of a computer program input to the control unit in advance for knitting socks, gloves, or the like, the core 33 of the electromagnet has an N-pole, as shown in fig. 5, and generates an attractive force with the S-pole permanent magnet 22ab of the signal detection unit 22, thereby spacing the lever 50 from the blade 20 and not transmitting the signal.
On the other hand, when a strong S-pole is generated by inputting a current to the electromagnet, as shown in fig. 6, even if the iron core 33 of the electromagnet has an N-pole, an attractive force is generated with the N-pole permanent magnet 22aa of the signal detection unit 22, and the operating unit 21 of the operating piece 20 is angularly moved to transmit a signal to the lever 50.
While the invention has been described with reference to one embodiment shown in the drawings, it is to be understood that various changes may be made and other embodiments may be made by those skilled in the art.
