Drive control device of a rotation member, method for drive control of a rotation member, and image forming apparatus including the drive control device |
摘要 |
A drive control apparatus including a drive motor that transmits a rotation drive force to a rotation member in order to rotate the rotation member, a pulse signal outputting unit that outputs a pulse signal for each predetermined angle of rotation or a position for rotation of the rotation member, while the rotation member is rotating, a pulse cycle measuring unit that measures a pulse cycle of the pulse signal, where the pulse cycle is a cycle of a rising or falling edge, a computation processing unit that computes an angular error or a position error of the rotation member based on the pulse cycle and a desired pulse cycle, where the desired pulse cycle corresponds to a desired velocity of the rotation member and a drive control unit that controls the drive motor based on the angular error or the position error. |
