PROBLEM TO BE SOLVED: To obtain a general-purpose loading machine by which a printed-circuit board is loaded with good efficiency even when the printed-circuit board is small by a method wherein a first conveyance passage and a second conveyance passage are driven simultaneously in the same direction and all printed-circuit boards on the first conveyance passage are moved onto the second conveyance passage. SOLUTION: When printed-circuit boards Ws are large, a first conveyance passage 31 and a second passage 32 are driven integrally, and the printed-circuit boards Ws are loaded. On the other hand, when printed-circuit boards Ws are small, they are arranged at equal intervals on the first conveyance passage 31 which is standstill. Immediately after the second conveyance passage 32 in a next stage has loaded a laste printed-circuit board W, the first conveyance passage 31 and the second conveyance passage 32 are synchronized and driven at a speed which is faster than the drive speed of the second conveyance passage 32 up to this time, and all the printed-circuit boards Ws on the first conveyance passage 31 are transferred onto the second conveyance passage 32 in a short time. Then, the respective printed-circuit boards Ws which are transferred to the second conveyance passage 32 are loaded, and the second conveyance passage 32 is driven at a speed corresponding to the processing time of a processing part. |
