and a second support shaft. 15 is a support plate that supports the lower end of the magazine 1. In addition, in Figure 3 B, the discharge cylinder 1
0, the ejection lever 11 is omitted. Next, to explain the operation of the electronic component supply device shown in Fig. 3 A, B and Fig. 4, a suction nozzle (not shown) is
picks up the electronic components pushed up by push-up pins (not shown) one by one in the magazine,
When the conveying operation continues and all the electronic components in the magazine are absorbed, the magazine becomes empty. At this point, when the ejection cylinder 8 descends, the ejection lever 11 rotates clockwise around the first support shaft. Then, the empty magazine 1 is removed from the support of the support plate 15, and the magazine 1 is ejected by falling under its own weight in the direction of the arrows in FIGS. 3A and 4.

(c) Problems to be solved by the invention In the electronic component supply device shown in Figures 3A and 3B and Figure 4 above, when the empty magazine is ejected, the stopper and the empty magazine are connected to each other. There is a problem that friction may occur and it may become stuck.

(d) Means for Solving the Problems The present invention was made to solve the above problems, and consists of a cylindrical magazine in which a plurality of electronic components are stacked and housed, with the lower longitudinal end of the magazine stacked on top of each other. The electronic components in the magazine are stored in series in parallel on a support plate, and are supplied to the electronic component supply position so as to be placed one by one on the board, and substantially all of the electronic components in the magazine are In the electronic component supply device, after discharging the magazine that has completed supply of components from the electronic component supply position, supplying a magazine adjacent to the discharged magazine to the electronic component supply position, the magazines are arranged in series in parallel. a pressing means for pressing the magazines in the direction in which they are arranged in order to sequentially supply the electronic components to the electronic component supply position; a stopper for locking the magazines pressed by the pressing means; and a stopper for locking the magazines pressed by the pressing means; a pushing-back means for pushing back the magazine in the opposite direction to the direction of the pressing; and a pushing-back means for pushing back the magazine in the opposite direction to the pushing-back means, and then pushing the magazine, which has been supplied with substantially all the electronic components, by the support plate. The above-mentioned problem is solved by an electronic component supply device characterized by having a discharging means for pushing out the support so as to remove it and discharging it by its own weight.

(E) Effect The electronic component supply device of the present invention eliminates the friction between the stopper and the magazine that causes the magazine to get caught when the magazine is discharged from the electronic component supply position after the supply of electronic components in the magazine has been completed. In order to do this, the push-back means, which has been released from the pressing force of the pressing means, pushes back the magazine in a direction opposite to the direction of the pressing force, thereby creating a gap between the magazine and the stopper. The ejection means pushes out the magazine at the supply position so as to remove the support from the support plate, and ejects it by its own weight.

(F) Embodiment The electronic component supply device of the present invention will be explained according to the drawings. Figure 1 A and B are a plan view and a front view of the electronic component supply device of the present invention, respectively. The ejection means is omitted. Figure 2 shows the ejecting operation of the electronic component feeding device of the present invention.
-A sectional view. The same reference numerals in FIG. 1 A, B and FIG. 2 as in FIGS. 3 A, B and FIG. Reference numeral 13 indicates a return cylinder as a pressing means for pushing in the opposite direction, and 13 a stopper having a hole that penetrates the return cylinder.

Next, the operation of the electronic component supply device of the present invention will be described. In the electronic component supply position shown in FIGS. The electronic components are fed one by one into the upper part of the magazine by a push-up pin (not shown) that pushes up from the back side of the electronic components in the magazine from below the magazine, and are picked up and transported one by one by a suction nozzle (not shown). conduct. When all the electronic components in the magazine have been supplied, the air is removed from both ends of the feed cylinder 5 to make it free, and the return cylinder 12 is moved in the opposite direction to the transport direction, that is, in the direction of the arrow in Figure 1B. After pressing the magazine and creating a gap between the stopper 13 and the magazine, the ejection cylinder 8 is driven downward, the second support shaft 10 is lowered, and the ejection lever 11 is centered around the first support shaft 9. The magazine 1 is rotated clockwise until the magazine 1 is no longer supported by the support plate 15 and the magazine 1 falls due to its own weight, and the rotation continues until the ejection of the magazine is completed. When ejection is completed, the ejection cylinder 8 is moved upward. to return the ejection lever 11 to its original position.

Next, the feed cylinder 5 is driven in the magazine transport direction to feed the magazine, and the magazine adjacent to the left side of the ejected magazine in FIGS. 1A and 1B is fed to the electronic component supply position.
