Drive transmission mechanism
First Claim
1. A drive mechanism comprising:
- a drive shaft;
a drive wheel mounted on said drive shaft;
a driven shaft;
a driven wheel mounted on said driven shaft;
a support shaft;
said drive shaft, driven shaft, and said support shaft being axially parallel;
first intermediate wheel means disposed on said driven shaft and second intermediate wheel means disposed on said support shaft, said second intermediate wheel means being coupled to said first intermediate wheel means and to said drive gear such that said drive shaft drives said driven shaft via said first and second intermediate wheel means;
said first intermediate wheel means comprising at least one rotary wheel having one transmission part of one diameter and another transmission part of another diameter;
said second intermediate wheel means comprising at least one other rotary wheel having one transmission part of one diameter and another transmission part of another diameter;
said one transmission part of said one rotary wheel being operably coupled in driving relationship to said other transmission part of said other rotary wheel, said one transmission part of said one rotary wheel having an engaging end surface perpendicular to said axially parallel shafts, said other rotary wheel having a transverse contact surface perpendicular to said axially parallel shafts and contacting said engaging end surface to preclude axial relative displacement in one axial direction between said one and said other rotary wheels.

Abstract
A drive transmission mechanism comprising a drive wheel fixed to a drive shaft, a plurality of intermediate wheels supported by a support shaft and each having a first transmission wheel and a second transmission wheel different from each other in diameter and rotatable together, and a driven wheel fixed to a driven shaft, the drive wheel being coupled to the first transmission wheel of the first intermediate wheel counted from the drive side, the second transmission wheel of the (n-1)th intermediate wheel as counted from the drive side being coupled to the first transmission wheel of the nth intermediate wheel as counted similarly, n being an optional integer of not smaller than 2, the second transmission wheel of the last intermediate wheel as counted from the drive side being coupled to the driven wheel, at least two of the drive wheel, the intermediate wheels and the driven wheel being mounted on the same shaft rotatably relative to each other.
