Zusammenfassung:	PURPOSE:To smooth conveyance of nursery boxes to the next step, by constituting a sensor device so as to enable conveyance and guide of the nursery boxes at a nondectection position thereof. CONSTITUTION:When soil covering of nursery boxes is completed, an operator pushes down a crank type arm of a sensor device mounted on an auxiliary frame 8 together with a conveying and guiding means 12 to a position (F) after detection to hook an U-shaped hook 19. The top of the conveying and guiding means 12 is in agreement with those of other conveying rollers 22. Thereby the nursery boxes are smoothly conveyed on the rollers without disturbance as in the case of a conventional carrying conveyor stop level and then transferred to the next step.
