  In the sales standby state shown in FIG. 11, the solenoid 5 is not energized, and the link member 60 is urged downward by the return spring 66 (see FIG. 2). That is, the upper link pin 61 moves downward along a long hole 511 (see FIG. 5) formed in the bearing member 50 in the bearing portion 4, and the lower link pin 62 is a long hole formed in the bearing member 50 in the bearing portion 4. It moves downward along 512. In the sales standby state, the first stopper member 2 is in the protruding position by the elastic biasing force of the torsion coil spring 20a (see FIG. 2). Further, the first stopper member 2 receives the load of the commodity G because the commodity G1 is in contact with the holding surface. Further, in the sales standby state, the rotation stopper 7 is in a protruding position by an elastic biasing force of a torsion coil spring (not shown). Further, the rotation stopper 7 engages the small-diameter groove portion 25a (see FIG. 8) of the deformed groove 25 in the first stopper member 2 with the lock pin 71 so that the load of the product G applied to the first stopper member 2 is applied. is recieving. Further, the protruding position of the rotation stopper 7 is maintained by engaging the lower link pin 62 with the lock groove 7c (see FIG. 9). Thereby, the rotation stopper 7 keeps the 1st stopper member 2 in a protrusion position, and has prevented the movement to the retracted position of the 1st stopper member 2. FIG. Further, in the sales standby state, the second stopper member 3 is returned to the retracted position by an elastic biasing force of a torsion coil spring (not shown). In this case, the extending portions 32 </ b> A and 32 </ b> A of the second stopper member 3 return to the retracted position after passing through the extending portions 11 a and 11 a formed in the upper region of the opening 11 of the substrate 1. Further, the closing plate 20 hangs along the substrate 1.

  When the solenoid 5 is energized by the sales command from the sales standby state shown in FIG. 11, the solenoid 5 attracts the plunger 51 against the elastic biasing force of the return spring 66 to raise the link member 60. Then, the lower link pin 62 of the link member 60 rises and the engagement with the lock groove 7c of the rotation stopper 7 is released. By this unlocking, the rotation stopper 7 is rotated toward the retracted position about the rotation shaft 70 by the product load, and accordingly, the lock pin 71 is also detached from the small-diameter groove portion 25a of the deformed groove 25. 2 is released, and the first stopper member 2 is rotated toward the retracted position by the product load.

  At the same time, the second stopper member 3 protrudes from the retracted position toward the protruding position by the upper link pin 61 of the rising link member 60. That is, when the link member 60 is lifted from the sales standby state, the upper link pin 61 engaged with the sliding groove 33a of the second stopper member 3 is lifted. Then, the second stopper member 3 moves against the elastic biasing force of the torsion coil spring toward the projecting position about the rotation shaft 30. When the link member 60 rises to the upper limit position, the upper link pin 61 engages with the stopper surface 33b of the second stopper member 3 to lock the second stopper member 3 in the protruding position. In the process in which the second stopper member 3 moves from the retracted position to the protruding position, the tip (holding portion 32) of the second stopper member 3 is opposite to the back surface of the closing plate 20 (the surface that is exposed to the product storage passage 83). The closing plate 20 is pushed out into the product storage passage 83. That is, the closing plate 20 is pushed out into the product passage 83 in conjunction with the movement of the second stopper member 3 from the retracted position to the protruding position. The holding portion 32 of the second stopper member 3 that has reached the protruding position locks the next sale product G2 via the closing plate 20 that closes the gap between the substrate 1 and the holding portion 32, and the outlet adjustment plate 10A (FIG. 15), the next sale product G2 is held. As a result, the sale product G1 at the lowest position passes through the first stopper member 2 and is carried out (see FIG. 13).

  When the sales commodity G1 is unloaded and the first stopper member 2 is not subjected to the commodity load, the first stopper member 2 returns to the protruding position (sales standby position) by the biasing force of the torsion coil spring 20a (see FIG. 12). . At the same time, the rotation stopper 7 also returns to the protruding position by the elastic biasing force of the torsion coil spring. In this case, the lock pin 71 provided at the tip of the rotation stopper 7 slides on the wall surface of the large-diameter groove portion 25b of the deformed groove 25 in the first stopper member 2 and reaches the small-diameter groove portion 25a. As a result, the first stopper member 2 is locked at the sales standby position.

  When the solenoid 5 is de-energized, the link member 60 is lowered by the urging force of the return spring 66, so that the second stopper member 3 is unlocked by the upper link pin 61, and the second stopper member 3 is twisted. Return to the standby position by the biasing force of the coil spring. When the link member 60 is lowered to the lower limit position, the lower link pin 62 is engaged with the lock groove 7c of the rotation stopper 7 to maintain the first stopper member 2 at the sales standby position (see FIG. 13).
