<p>PURPOSE:To design a driving mechanism in a high degree of freedom by providing a rotor to be rotatively driven by a motor and a link mechanism for making a linkage between this rotor and a guide lever in the middle of the driving mechanism from the motor to the guide lever. CONSTITUTION:The motor 5 on a chassis 1 is connected with a 1st driving mechanism for driving a leading guide body 22 back and forth and a 2nd driving mechanism for driving a tape guide 91 back and forth. The 2nd driving mechanism is composed of the inclined guide lever 9 provided with a turnable tape guide 91, a stopper 15 for regulating a turning end of this lever 9 on the side of a tape traveling course, the rotor 26 to be rotatively driven by the motor 5 and the link mechanism 93 for making a linkage between the rotor 26 and the lever 9. The link mechanism 93 is provided with a motive lever 7 to be engaged with the rotor 26 and a spring 95 between the rotor 26 and the lever 9. The leading guide body 22 passes through a moving space for the tape guide 91 in a process of rotating the rotor 26 by a prescribed angle against the lever 7, while the lever 9 is pressed against the stopper 15 by the spring in its elastic deformation in a process of rotating integrally the lever 7 and the rotor 26.</p> |
