Title: Electronic part mounting device

Abstract: An electronic component mounting apparatus includes a plurality of pickup nozzles (1) which are attached to the periphery of a rotary table, that intermittently rotates. The apparatus also includes a cylindrical cam (105) having a cam groove (106, 107a, 107b) which allows the pickup nozzles (1) to move up and down. A first roller (5) is attached to a first slide portion (4a), which is equipped with the pickup nozzles 1. The first roller runs within the cam grooves (106, 107a, 107b) to make the pickup nozzles 1 move up and down. A second roller (6) is attached to a second slide portion 4b, which is attached to the pickup nozzles (1). The second roller runs within the cam grooves (106, 107a, 107b) to make the pickup nozzles move up and down together with the first roller. Also, springs (9) are provided for biasing the first and second rollers (5, 6) into contact with the two side surfaces, respectively, of the cam grooves (106, 107a, 107b).
