PURPOSE:To make it possible to prevent the damage of a daisy wheel, by performing the positional determination of a support table and the detachment of a daisy wheel by a detachment lever and protruding the daisy wheel after perfectly erecting the support table. CONSTITUTION:When the first stage pulling operation of a detachment lever 25 is performed against a tensile spring 28, said lever 25 is inclined around the pin 24 fixed to the bracket 26 of a support table 22 and a shaft rod 27 is taken out from a circular arc shaped hook part 25nk to be contacted with the lower rear surface of a slot 25n while a shaft rod 25 is transferred to the almost center of a circular arc shaped hole 25e and a bent part 25m is separated from a base plate 22k and a push-out part 25mp slightly approaches to a daisy wheel 6. By the succeeding second stage pulling operation, the detachment lever 25 is further inclined and, at the same time, the support table 22 is also contacted with a stopper 30 by a spring 29. When third stage pulling operation is performed to revolve the lever 25 against the spring 28 until the shaft rod 27 is inlaid with the recessed part 25nk, the push-out part 25mp pushes up the daisly wheel 6 to detach the same from a drive shaft 7 and said daisy wheel 6 is received by a receiving part 22d.
