Embodiment 1
[0041] Embodiment one, see Figure 2A , 2B , 2C, the figure shows the encoding device of the numbering machine of the present invention, which includes: a number of character wheels 100, the number of character wheels 100 is set according to the number of digits of the printed number, the present embodiment uses a 12-digit numbering machine For example, 101 among the figure is numbering machine, and it comprises 12 printing character wheels 100, see Figure 2C , the circumferential surface of each character wheel 100 is provided with evenly distributed printed characters 102: respectively arranged evenly in the clockwise direction: 0, empty, X, 1, 2, 3, 4, 5, 6, 7, 8,9. Eight magnetic elements 103 are arranged on the character wheel 100, and a sensor unit 104 is arranged near the outer circumference of the character wheel 100; the magnetic element 103 is used to send a magnetic signal to the sensor unit 104, and the magnetic element 103 includes 4 N-pole magnetic elements 10...
Embodiment 2
[0087] Example 2, see image 3 , the figure shows another encoding device. The difference from the previous embodiment is that there are three Hall elements 104A, 104B, and 104C, of which 104A and C are effective Hall elements triggered by S-pole magnetic elements. 104B is an effective Hall element of the N-pole magnetic element, and the trigger output of the Hall element is 0, and the detection code corresponding to each character detection is:
