[0022]
As shown in FIG. 11, in the reel control process (FIG. 9), eight types of excitation pulse data (PI = 0 to 7) output to the stepping motor side, and the interrupt interval for performing step update is determined by switching the pulse data. A reel drive data table TB is used which stores a large number of set data composed of an interrupt count value IRcnt and an update step number ST for performing step update with the same count value. Each stepping motor PML, PMC, PMR has, for example, 400 steps per rotation.
[0023]
At the initial entry of the reel control process, the update step number ST is 0 (b), and the interrupt count value IRcnt and the update step number ST are acquired from the first in the reel drive data table TB (c, d, e, f, g). ). The next time this process is passed, it will be acquired from the second (h). The interrupt count value acquired at d is set in the register by the processing at a1.
[0024]
The value of the update step number ST is decremented by 1 (i), the output data selection pointer PI is updated (k), and the value is adjusted to a range of 0 to 7 (l). Next, output data is acquired based on the output data selection pointer PI and stored in the RAM (n). The output data stored here is output to the port in the process of a2.
[0025]
In this way, the output data selection pointer PI is updated and the excitation pulse is updated for each set interrupt count value IRcnt (k). This update is repeated for the update step number ST of the set data, and the stepping motor rotates a step angle corresponding to the update step ST number of the set data. Then, ST = 0 (b), the next interrupt count value IRcnt and the update step number ST are acquired (c to h), and the same processing is performed thereafter.
