回路。 In a magnet drive circuit in which a driving transistor is connected in series with the magnet and a driving current is caused to flow through the magnet by turning on the driving transistor, the driving transistor is connected to the magnet for a predetermined moving time or more. a first drive control means that continuously drives the driving transistor to flow a moving current; and a second drive control means that, after the certain period of time, intermittently drives the driving transistor with a drive pulse having a constant duty ratio at a certain period to flow a holding current. 1. A magnet drive circuit comprising: means.
