A gear train comprising a driving gear and at least two driven gears respectively engaged with the driving gear. Multiple teeth of the driving gear can be accommodated between two adjacent teeth of each driven gear, the number of said teeth of the driving gear that can be accommodated between two adjacent teeth of each driven gear is equal to the number of the driven gears. The engagement of the driving gear with each driven gear is in order and in sequence, i.e., the driving gear engages each driven gear alternately. The invention teaches reduction of the number of the teeth of the driving gear.
