PROBLEM TO BE SOLVED: To reduce the operation noise of a gear train and an ink-jet printer using the same, to reduce the vibration in operation, and to reduce the cost by reducing the number of components. SOLUTION: A first double helical gear 5 is integrally rotatably mounted on an output shaft 4 of a motor 3. A second resin double helical gear 6 engaged with the first resin double helical gear 5 is integrally rotatably mounted on a paper supply roller shaft 7 as a driven shaft. Whereby the rotation of the motor 3 is transmitted to the paper supply roller shaft 7 through the first and second resin double helical gears 5, 6. The first and second resin double helical gears 5, 6 are manufactured by injection molding with high accuracy. COPYRIGHT: (C)2005,JPO&NCIPI |
