description PROBLEM TO BE SOLVED: To finely control a motor with a simple configuration.SOLUTION: A motor control device controls a motor by transmitting a pulse to a motor driver. The motor control device includes a memory which stores a control table that contains a count number of a reference clock representing a timing for generating a next pulse, a first register which stores a target generation frequency of a pulse, a second register which reads the count number from the memory and stores it, a control part which specifies a target occurrence frequency of a pulse at the first register and specifies an address of the memory which the second register references first at the second register, an address counter which changes an address of a memory from which a count number is read according to occurrence frequency of a pulse, a comparator which stops operation of the address counter when an occurrence frequency agrees with a target occurrence frequency, and a pulse generator which generates a next pulse when a count number that is read from the second register expires after a previous pulse. 【課題】簡易な構成でモータを細かく制御する。【解決手段】本発明は、パルスをモータドライバに送信することによりモータを制御するモータ制御装置であって、次のパルスを発生させるタイミングを示す基準クロックのカウント数を含む制御テーブルを記憶するメモリと、パルスの目標発生回数を記憶する第1レジスタと、メモリからカウント数を読み出して記憶する第2レジスタと、パルスの目標発生回数を第1レジスタに指定し、第2レジスタがはじめに参照するメモリのアドレスを第2レジスタに指定する制御部と、パルスの発生回数に応じて、カウント数を読み出すメモリのアドレスを変更するアドレスカウンタと、発生回数と目標発生回数とが一致したときに、アドレスカウンタの動作を停止させる比較器と、前回のパルスを発生させてから、第2レジスタから読み出したカウント数だけ待った後、次のパルスを発生させるパルス発生器と、を備える。【選択図】図1
