Patent JP-H0872350-A (JP)
Title: Recorder
Inventor: TAKAHASHI YOSHINORI
IPC: H02P7/06
Filed: 1994-08-30
Abstract: PURPOSE: To prevent the flow of a large current to a motor at the time of application of negative voltage to the motor by driving a second drive part smaller in load than a first drive part by smaller drive force after the driving of the first drive part. CONSTITUTION: A period of t2 -t3 is a recording region and emission is performed in the timing based on linear pulses and chopper control is performed between voltage +E1 and voltage +E2 on the basis of a motor pulse signal to keep the speed of a carriage constant. A period of t3 -t4 is a period performing paper feed and voltage +E3 is applied to a DC motor. Voltage +E3 has a value smaller than that of voltage +E1 but, since the load of paper feed is smaller than the driving load of the carriage, a sufficient paper feed speed is obtained. A period of t4 -t5 is an inverse exciting region and inverse voltage -E3 is applied to sufficiently reduce the speed of the DC motor and a motor is short-circuited for a predetermined time from t5 to be stopped to complete recording processing.
