In the automatic insertion device, an electronic component provided with a cylindrical guide member for guiding the lead wire guide pin at the tip of a guide pin cartridge in which a plurality of lead wire guide pins for guiding the lead wire of the electronic component are mounted so as to be movable up and down. Automatic insertion device. 2. An electronic component which inserts an electronic component into a circuit board in a state in which the lead wire of the electronic component is guided by inserting the lead wire insertion hole from below the lead wire insertion hole of the electronic component provided on the circuit board. In the automatic insertion device, the guide pin cartridge in which a plurality of lead wire guide pins for guiding the lead wires of the electronic component are mounted so as to be able to move up and down is provided with a mounting groove for mounting the lead wire guide pin independently. Automatic insertion device for electronic components. 3. An electronic component for inserting an electronic component into a circuit board in a state in which the lead wire of the electronic component is guided by passing through the lead wire insertion hole from below the lead wire insertion hole of the electronic component provided on the circuit board. In the automatic insertion device, a guide pin cartridge in which a plurality of lead wire guide pins for guiding the lead wires of the electronic component are mounted so as to be able to move up and down is formed with a guide groove so that the plurality of lead wire guide pins are linearly arranged. An electronic component automatic insertion device which is provided and divided so as to have a cut surface in the guide groove portion. 4. An electronic component for inserting an electronic component into a circuit board in a state where the lead wire of the electronic component is guided by inserting the lead wire insertion hole from below the lead wire insertion hole of the electronic component provided on the circuit board. In the automatic insertion device, a rubber or resin provided with a fitting hole at the tip of a push rod for pressing the top of the electronic component when the electronic component is inserted into a circuit board, and a convex portion that fits into the fitting hole. An automatic electronic component insertion device in which an attachment member made of a material is detachably attached to the tip of a push rod.
