Abstract

A method for controlling a step motor of a scanner by using three parameters is provided. The three parameters include a pulse count number PCN, a count base CB, and a motor constant speed interval MCSI. The method includes the following steps. First, generate a synchronous trigger signal in correspondence with each exposure trigger signal generated by CVTR generated by an image- sensing module of the scanner and clear a base accumulator BA. Then, add the count base CB to the base accumulator BA in correspondence with each reference pulse. Finally, generate an asynchronous trigger signal and clear the base accumulator when the base accumulator is greater than or equal to the pulse count number PCN. Since the acceleration and deceleration of the step motor only relates to the pulse count number PCN and the count base CB, the step motor can be controlled by only setting these parameters.

Description of the invention (5) (motor constant speed interval) MCSI, etc. Pulse count value PCN system Used to determine the period of the trigger signal of the asynchronous motor. The counting base C B has two functions. One function is to adjust the motor speed (used as the cumulative base for the trigger signal of the asynchronous motor), and the other function is to use it as the reduction ratio of the acceleration and deceleration of the motor during tracking control. In addition, the third control number is the motor constant speed interval MCS I, which is used to set the number of steps that the motor speed will be slower during the backtracking control. The calculation method of the pulse count value PCN is the number of pulses of the reference frequency R-CLK calculated by the mother and secondary exposure time (E-time) of the image sensor module of the scanner, which is a function as shown in formula (1) ：, PCN = E — time * R —CLK… (1) For example, for a scanner with a reference frequency of 0.25MHz, 2400dpi, and which can scan 8 5 ”documents, if the data transmission rate of the CCD is ^“ 3, its c⑶ With 20400 (2400 * 8.5) sensing units, its exposure time is 4.08ms (2 0400 0/5 (MB / s)), so its pulse count value PCN is 1 020 (4.08ms * 〇 · 25ΜΗζ) .

Case No. 89116317 V. Description of the invention (6) Asynchronous trigger signal ASTR provides a trigger signal to the stepping motor by OR operation method, thereby driving the stepping motor to rotate. As shown in Fig. 1, a synchronous motor trigger signal STR is generated at the trailing edge of each exposure trigger signal CVTR, and a base accumulator BA is cleared at the leading edge of the exposure trigger signal CVTR. The base cumulated value ba is calculated according to the formula (2): BA = BA + CB --- (2) When the base cumulated value BA > = PCN, in addition to generating an asynchronous motor touching 1¾ k ASTR, it also simultaneously Clear the accumulated base value β a to q, and count again. According to the definition of the pulse count value PCN, it is understood that within one cycle of the exposure trigger signal CVTR, the reference pulse number set by the pulse count value pCN will be generated. Therefore, when counting the base (^ is!, Because the base cumulative value BA has not been greater than or equal to the pulse count PCN, that is, cleared by the exposure trigger signal cvtr ', so only the synchronous motor trigger signal will generate a motor trigger pulse. When counting the base CB When it is 2, the base cumulative value BA is increased by 2 each time, so the asynchronous motor trigger signal ASTR will generate a pulse at about half of the exposure trigger signal CVTR. In this case, the synchronous motor trigger signal STR and the asynchronous motor The trigger signal "^ will generate 2 motor trigger pulses in one exposure trigger signal CVTR cycle, and the speed of the stepper motor will be doubled. In the example shown in Figure 1, because the count base CB is 4, it is asynchronous. The motor trigger signal ASTR generates a motor trigger pulse at approximately 1/4 1/2 and 3/4 positions of the exposure trigger signal CVTR, respectively. In this case, the synchronous motor trigger signal STR and the asynchronous motor trigger signal "^ will be at One exposure trigger signal generates 4 motor trigger pulses in a period

Therefore, the speed of the stepping motor can be controlled by different counting base CB values. Referring to Table 1, the relationship between the pulse count value PCN, the count base CB, and the resolution DP I of the scanner is shown.

If the resolution is reduced to 1 20 0dpi46 0 0dpi, as long as The counting base ⑶ can be changed to 2 or 4. ί ί: ϊ ί Ϊ: simple.

"RU t base number" is for example 2, 4, or 8. In this way, the count & number CB value can be increased, and the acceleration and deceleration of the motor can be changed without affecting the control of the running speed.

And counting base CB, you can surely control the start of the motor. The pulse count value PCN and the count base CB filled in the accelerometer can have different changes, which are described as follows: The first method is to fix the pulse count PCN and adjust the count base CB. That is, the pulse count value pcn is fixed, and the count base CB is adjusted from small to large in order, for example, the count base CB is adjusted from 1 to 32. Since the counting base CB gradually increases from 1 to 32, if the counting base cb is 1, its resolution is 240 0 DPI, and when the counting base cb is 32, its resolution is 75 DPI. Therefore, after the control process is over, the motor will continue to rotate at a speed of 7 5 DP I to perform the pre-scanning fast scanning action. The second method is to adjust the pulse count PCN and fix the count base CB. That is, the count base CB is fixed, and the pulse count PCN is adjusted from large to small in order. The third method is to adjust the pulse count value PCN and the count base CB at the same time. [Inventive effect]
