Abstract
A tape guide mechanism includes a shaft having one end fixed to a base, a guide part provided in a predetermined position on the shaft to guide a tape, and a vibrating element capable of vibrating the shaft either in a first vibration mode or in a second vibration mode. In the first vibration mode, the tape is caused to travel at a predetermined normal speed. In the second vibration mode, the tape is caused to travel at a higher speed than the predetermined normal speed.
Claims22
A tape guide mechanism comprising:
- a) a shaft having one end fixed to a base;
- b) a tape guide, provided in a predetermined position on said shaft, for guiding a tape;
- and
- c) means for directly vibrating said shaft in a first vibration mode and in a second vibration mode, wherein, in the first vibration mode, the tape is caused to travel at a predetermined normal speed and, in the second vibrational mode, the tape is caused to travel at a higher speed than the predetermined normal speed, said vibrating means being axially spaced from said tape guide.
A tape guide mechanism comprising:
- a) a shaft having one end fixed to a base;
- b) means for directly vibrating said shaft;
- and
- c) a tape guide for guiding a tape, said guide being fixed to said shaft approximately at a barycentric position of said guide and axially spaced from said vibrating means, the position of said shaft at which said guide is fixed being one of at a position where said shaft is displaced by vibration approximately to a maximum vibration amplitude extent at about zero angle of displacement and at a position where said shaft is displaced by vibration approximately to zero vibration amplitude extent at about a maximum angle of displacement.
A tape guide mechanism comprising:
- a) a shaft having one end fixed to a base, said shaft being composed of two parts which differ in rigidity;
- b) a guide, provided in a predetermined position on said shaft, for guiding a tape;
- and
- c) means for directly vibrating said shaft, said vibrating means being axially spaced from said guide.
A tape guide mechanism comprising:
- a) a shaft having one end fixed to a base;
- b) means for directly vibrating said shaft;
- and
- c) a guide, provided in a predetermined position on said shaft and axially spaced from said vibrating means, for guiding a tape, said guide being vibrated derivately from vibration of said shaft.
A tape guide mechanism comprising:
- a) a shaft having one end fixed to a base;
- b) a vibrator;
- and
- c) a tape guide axially spaced from said vibrator,
- said shaft being disposed between said vibrator and said tape guide, such that upon vibration of said shaft by the vibrator, said shaft vibrates the tape guide.
