Mounting mechanism for gear

Abstract

Abstract PURPOSE:To minimize an influence exercised on engagement of a gear with the one fixed shaft when engagement of a gear with the other fixed shaft is ensured, by a method wherein a gear train is formed on a rotary member being rotatable around a reference point. CONSTITUTION:Shafts 23a-23d and 25 of a drive system driven by a motor 21 are mounted on a frame 13, and the frame 13 is constrained except that only rotation around a shaft 19 serving as a reference point is effected in a free direction. Therefore, when engagement of a gear 26, secured on a shaft 27, with an intermediate gear 22d and engagement of a gear 28, secured on a shaft 29, with an intermediate gear 24 are ensured, the ensurance takes place through rotation of a frame 13 around the shaft 19 serving as a reference point. In which case, since the shafts 19 and 27 are independently mounted on a chassis, mounting on the frame 13 has a factor by which the occurrence of unevenness is caused. However, since an engagement part between the gears 28 and 24a is positioned on a straight line for interconnecting the fixed shaft 29 and the rotary reference point 19, even when unevenness in the mounting position on the frame 13 occurs, the uneveness is difficult to influence engagement between the gears 28 and 24a.
