Abstract

PURPOSE:To prevent a spacing motor from damaging due to an excess rising in the temperature of the motor by stopping a spacing action if the motor temperature becomes higher than a threshold temperature and restarting the spacing action if the motor temperature becomes lower than the threshold temperature. CONSTITUTION:A temperature detector 6 detects the temperature of a spacing motor 5. A control circuit 3 temperarily interrupts a signal to a driver circuit 4 from a spacing circuit 1, if the spacing motor temperature 5 becomes higher than the threshold temperature specified by a threshold temperature instruction part 2. On the other hand, the temperature detector 6 connects a signal to the driver circuit 4 again, if the spacing motor temperature 5 becomes lower than the threshold temperature. Further, the temperature detector 6 converts the surface temperature of the spacing motor 5 to a temperature signal using a thermocouple. It is possible to obtain a temperature signal based on the variations of a winding resistance value in the spacing motor 5 instead of using the thermocouple.

を行なっていた。° [Prior art] The spacing motor that drives the carriage carrying the print head of a serial printer in the lateral direction requires a large drive torque, so the drive current is large and therefore generates a large amount of heat. However, the spacing motor Conventional spacing control methods control the spacing motor regardless of the temperature rise due to heat generation of the spacing motor.

It has the disadvantage of being destructive.

４に信号を送り、スペーシングを再開させる。Referring to FIG. 1, a temperature detector 6 detects the temperature of the spacing motor 5. As shown in FIG. The control circuit 3 temporarily interrupts the signal from the spacing circuit 1 to the driver circuit 4 when the spacing motor 5 reaches a certain limit temperature specified by the limit temperature instruction section 2, and also controls the spacing motor 5. When the temperature falls below the limit command temperature, a signal is sent to the driver circuit 4 again to restart spacing.

Also, instead of using a thermocouple, a temperature signal can be obtained based on changes in the resistance of the windings inside the spacing motor.

This has the effect of preventing destruction of the spacing motor due to an excessive rise in temperature of the spacing motor.
