Title:
CONTROLLER FOR ELECTROMAGNETIC TRANSDUCER, IMAGE FORMING DEVICE AND IMAGE FORMING SYSTEM
Document Type and Number:
Japanese Patent JPH08125803
Kind Code:
A
Abstract:

PURPOSE: To realize a device and a system at a low cost by reducing the number of components in a protection circuit for an electromagnetic transducer such as plural solenoids and electromagnetic clutches used for paper feeding or the like.

CONSTITUTION: Solenoids 101-103 are controlled individually by way of drive transistors(TRs) 107-109 by a control means 114, which is configured so that plural solenoids are never driven simultaneously. Thus, a current interrupt means 115 is provided in common to the solenoids 101-103 in place of provision of a current interrupt means in series with each solenoid and the similar function of the provision of the current interrupt means in series with each solenoid is realized.
