PURPOSE:To hold surely a printed circiut board by providing the vertically movable 1st holding pawls, disposing alternately the 2nd holding pawls which press the printed circuit board and turning the 2nd holding pawls in the up position. CONSTITUTION:The vertically movable 1st holding pawls 51 are provided and the side edges of the circuit board 1 are imposed to the pawl parts 52 thereof. Rods 53 are provided integrally to the pawls 51 and are fitted to connecting parts 7a of a chain 7. The 2nd holding pawls 61 are disposed alternately with the 1st pawls 51 to the connecting parts of the chain 7 so that the circuit board 1 can be pressed downward. The 2nd holding pawls 61 move upward the rods 63 and press compression springs 66 when the conveying chain 7 travels. The circuit board 1 is then inserted and the printed circuit board 1 is surely held by the cooperative effect of the 1st holding pawls 51 and the 2nd holding pawls 61. |
