Filed: 1983-08-31
Abstract: PURPOSE:To obtain a precise device which eliminates the need for installation space by providing a speed reducing mechanism which uses a planetary gear mechanism between a rotary driving source and a head carriage and a rotary- linear motion converting mechanism. CONSTITUTION:The planetary gear speed reducing mechanism transmits the rotation of a stepping motor 12 from a pinion 22 to the planetary gears 26, which engage the pinion 22 and a fixed internal gear 24 to rotate around the pinion while rotating on their axes, thereby rotating a retainer 34. Planetary gears 32 while rotating on their axes rotate around the pinion through the retainer 34 to transmit the rotation to a rotary internal gear 28 while reducing the speed. The external gear 40 of the gear 28 engages a sector gear 44. The rotary-linear motion converting mechanism rotates a gear 44 together with the external gear 40, and the head carriage 14 is linked to the gear 44 through a steel belt 48 to perform comversion to linear movement. Consequently, the turning force of the motor 12 is reduced in speed at a high speed reduction ratio through the planetary gear mechanism. The reduced turning force moves the head carriage 14, track by track, by the rotatary-linear motion converting mechanism along a guide bar 18.
