Abstract
Each of the wheeled worktables , which is isolated from the others, travels self-dependently with drive of the motor M and the sensor (optical recognition device) is provided on each wheeled worktable while the optical recognition tape T as the recognition object for the sensor is attached to the predetermined conveyance passage on the floor for inducement of the wheeled worktables . Since the modification of the conveyance passage to meet any need of increase or decrease of the wheeled worktables is carried out only by reattachment of the optical recognition tape T, the passage can be modified into any form by a simple operation without generation of useless spaces between the adjoining wheeled worktables and, without any mechanical restraint on the wheeled worktables, replacement of the wheeled worktables for any increase or decrease in the wheeled worktables do not require such labor and time for dismounting from and remounting on the chain as in the case of the assembly line driven with the endless chain.
