While overlapping with 542E in the front-rear direction, the other abutment protrusions 714AA to 714C are positioned away from the engaging portions 542A to 542C of each link member 541. It is moved in the left direction to.

  Now, in the sales standby state, the payout mechanism 50 constituting the product carry-out device 5 has the first stopper member 52 protruding into the product storage passage 43 and the second stopper member 53 retracted from the product storage passage 43. In this case, the cam projection 6151 of the output gear 615 of the motor drive unit 61 is located at the uppermost position (see FIG. 19A). Further, the carrier switch 616 pressing piece provided on the upper portion of the output gear 615 is located at the foremost position, and the carrier switch 616 is in the ON state. As a result, the motor 611 is stopped, the tip end portion 617b of the link lever 617 is separated from the connecting member 62, and the connecting member 62 is allowed to descend, and is connected to the slits 712 and 712 formed on both leg pieces of the switching portion 711. The switching member 71 of the selective switching drive mechanism 70 to which the engaging piece 621 of the member 62 is inserted and connected is also lowered. For this reason, the link member 541 of the payout mechanism 50 is in a state of moving backward due to the urging force of the return spring 540. Further, the first stopper member 52 is in a protruding position opened to the maximum opening degree by the biasing force of the torsion coil spring 527. The rear link pin 55 supported by the link member 541 is opposed to the tip of the locking projection 523 in the first stopper member 52. The second stopper member 53 is maintained at the retracted position when the front link pin 56 supported by the link member 541 enters the sliding groove 535 of the second stopper member 53.

  In such a standby state, the first loaded product rolls or slides in the product storage passage 43 and comes into contact with the first stopper member 52 at the protruding position. In this case, the first stopper member 52 moves rearward from the maximum opening degree by the urging force of the torsion coil spring 527, and the tip of the locking projection 523 contacts the rear link pin 55 to hold the product. It is locked in the state. The product loaded first in this manner is held by the first stopper member 52 and becomes the product with the highest sales order (sales product G). The subsequently loaded products are sequentially stacked on the sales product G.

  After the selection switching drive mechanism 70 selects one of the plurality of payout mechanisms 50 based on the operation of the product selection switch and connects it to the drive unit 60, the drive unit 60 is driven. Now, as shown in FIG. 23B, if the link member 54 </ b> A of the rightmost payout mechanism 50 is connected to the drive unit 60 via the selection switching drive mechanism 70, the payout mechanism 50 by the selection switch drive mechanism 70. Subsequently to the selection operation, the motor 611 built in the motor drive unit 61 in the drive unit 60 is driven to rotate forward, and the output gear 615 is rotated in the clockwise direction in FIG. Rotate to. When the output gear 615 rotates, the pressing piece provided on the upper portion of the output gear 615 is detached from the contact of the carrier switch 616, the carrier switch 616 is turned off, and then the carrier switch 616 is turned on (that is, The period until the output gear 615 rotates once) The motor 611 is driven to rotate forward. When the cam projection 6151 comes into contact with the base end portion 617a of the link lever 617 from the front by the rotation of the output gear 615, the link lever 617 rotates in the counterclockwise direction in FIG. By rotation of the link lever 617 in the counterclockwise direction, the tip end portion 617b comes into contact with the U-shaped bottom portion 620 of the connecting member 62 so that the connecting member 62, the switching member 71, and the link member 541 are returned to the return spring 540. Move (rise) forward against the urging force of. While the cam protrusion 6151 is in sliding contact with the base end portion 617a of the link lever 617 (see FIG. 19B), the link member 541 is held in the raised state.

  As the link member 541 is raised, the rear link pin 55 supported by the link member 541 is also raised, and the lock of the first stopper member 52 locked at the protruding position by the rear link pin 55 is released. As a result, the first stopper member 52 moves toward the retracted position against the urging force of the torsion coil spring 527 due to the load of the product. Due to the movement of the first stopper member 52 to the retracted position, the sales commodity G passes through the first stopper member 52 and is carried out rearward. When the sales commodity G passes through the first stopper member 52, the first stopper member 52 returns to the protruding position opened to the maximum opening degree by the biasing force of the torsion coil spring 527.

  On the other hand, in the standby state, the second stopper member 53 maintained at the retracted position by the front link pin 56 coupled to the link member 541 is supported by the link member 541 and the front link pin 56 that rises is supported by the slide groove 535. Is pushed out toward the protruding position by abutting against the upper wall surface. Then, when the front link pin 56 moves up to a position facing the stopper surface 534 of the stopper wall 532 in the second stopper member 53, the movement of the second stopper member 53 to the retracted position is restricted by contacting the stopper surface 534. Is done. And the 2nd stopper member 53 which moved to the protrusion position contact | abuts and hold | maintains the 2nd sales order goods (next sales goods G) which move back by the sales goods G being carried out, and the next sales goods G Is restricted from moving backwards.

  The operation of moving the second stopper member 53 from the retracted position to the protruding position and holding the next sold product G while retracting the first stopper member 52 to the retracted position is performed by the output gear 615. It is executed during a predetermined time when the cam projection 6151 is in sliding contact with the base end portion 617a of the link lever 617.

  When the contact between the cam protrusion 6151 and the base end portion 617a of the link lever 617 is released by the rotation of the output gear 615, the link member 541 (and the connecting member 62, the switching member 71) is urged by the urging force of the return spring 540. Descends. As the link member 541 descends, the rear link pin 55 supported by the link member 541 moves to the movement locus of the tip of the locking projection 523 of the first stopper member 52 that has returned to the protruding position. Further, the front link pin 56 supported by the link member 541 by the lowering of the link member 541 enters the sliding groove 535 of the stopper wall 532 in the second stopper member 53 and comes into contact with the lower wall surface, thereby causing the second stopper. The member 53 is moved toward the retracted position. Due to the movement of the second stopper member 53 to the retracted position, the next sale product G held by the second stopper member 53 moves downward and contacts the first stopper member 52 opened to the maximum opening. As a result, the first stopper member 52 moves rearward from a state where the first stopper member 52 is opened to the maximum opening degree, and the next sale product G is held as the sale product G when the front end of the locking projection 523 comes into contact with the rear link pin 55. It is locked and enters a standby state. Thereafter, when the cam projection 6151 returns to the standby position by the rotation of the output gear 615, the contact of the carrier switch 616 is pressed by the pressing piece, and the carrier switch 616 is turned on. As a result, the drive of the motor 611 is stopped, and the payout mechanism 50, the drive unit 60, and the selection switching drive mechanism 70 are returned to the sales standby state.
