A plurality of component clamping mechanisms for sequentially clamping the electronic components supplied from the device and transporting the electronic components to the processing device in the next step, and closing the pair of clamping claws when one of the component clamping mechanisms faces the parts feeder and stops. And a claw closing mechanism for holding the electronic component by one hand, and when one of the component holding mechanisms stops facing the processing device of the next step, the pair of holding claws are opened to move the electronic component to the processing device of the next step. Supply to An electronic parts aligning / conveying device, comprising: 3. A rocking base configured to move toward and away from a parts feeder for continuously supplying electronic components, and which is driven by a cam mechanism to rock around a fulcrum, and disposed on the rocking base. It is attached to a winding transmission member wound around a pair of toothed rotary members, and is configured to rotate intermittently as the winding transmission member travels and to approach or separate from each other, and is always closed by a spring. A plurality of component clamping mechanisms for clamping the electronic components supplied from the parts feeder by the pair of clamping claws that are biased to A pawl opening mechanism that opens the pair of clamping pawls against the force of the spring, and a pawl closing mechanism that is driven by a cam mechanism to disengage the opening pin from the pair of clamping pawls and close the pair of clamping pawls. When one of the component clamping mechanisms faces the parts feeder and stops, the rocking base is swung to bring the parts clamping mechanism closer to the parts feeder, and the claw closing mechanism is operated to operate the claw closing mechanism. After the pair of clamping claws are closed to clamp the electronic components supplied from the parts feeder, the rocking base is rocked in a direction to separate from the parts feeder to intermittently travel the winding transmission member for a predetermined distance. By repeating the operation, the electronic parts supplied from the parts feeder are sequentially held by the parts holding mechanism, and when one of the parts holding mechanisms stops facing the processing device of the next step, the claw opening mechanism is operated. An electronic component aligning / conveying device configured to sequentially supply the electronic components sandwiched by opening the pair of clamping claws to the processing device in the next step.
