To efficiently carry a carried work regardless of length of the carried work.

This conveyor system is constituted by constituting a basic unit 1 with a transmission means (bevel gear) both end parts of a plurality of roller parts 40 of which are supported free to rotate on a holding plate of a driven side holding part 10 and a driving side holding part 20 arranged face to face, a drive shaft 31 of the driving side holding part 20 of which is arranged free to rotate at right angles with the roller parts 40 on the side of one end part of each of the roller parts 40 and to transmit rotation of the drive shaft to each of the roller parts 40, constituting a conveyor unit 2 by providing a motor to drive the drive shaft of either one of the basic units 1 a plural number of which are connected to each other by connecting the drive shafts of the basic units 1 adjacent to each other by arranging a plural number of the basic units 1 to each other in series by a coupling and a control circuit means to control driving of the motor and arranging a plural number of the conveyor units 2 in series.
