Abstract
PURPOSE:To make tension degree uniform by a printer wherein an ink ribbon is biased in one direction to impart tension thereto and winding or feeding of the ink ribbon is performed in accordance with the result obtained from a means for detecting a position of a tension imparting means. CONSTITUTION:A tension detecting switch 22 is connected to a pulse motor control circuit, and with the switch 22 turning on, clock pulses from a pulse gennerator 24 are fed to the up side of an up-and-down counter 25. The counter 25 operates in a quadruple mode and causes a four-phase pulse motor 18 to step forward for each pulse in the direction D through a decoder 26 and a driver 27 until the tension detecting switch 22 will be turned off. When a drive roller 14 is rotated in the direction N inversely, an ink ribbon 33 is pulled and a lever 23 moves in the direction C so that a tension detecting switch 29 is turned ON. Upon this, the clock pulses from the generator 24 are fed to the down side of the counter 25, thereby a motor 18 causes an ink ribbon spool 17 to rotate in the direction E.
