<p>An article merchandising machine (10) has an article gripper (270) moved by a robotic transporter (190) in a transport plane between an access port (62) and video cassette storage cells (98) mounted in doors (34, 36) on the machine. The transporter also moves the gripper in a direction intersecting the transport plane. The gripper (270) is moved under programmed control of a computer (64) and data inputted from a keypad (56) and card reader (58) to perform merchandising transactions. An emergency storing bin (88) accepts articles for return only during transaction shutdowns caused by robotic transporter malfunctions which persist after a recovery process. Transactions aborted by failure of a scanner (186) to read identification data on articles returned to the access port may be resumed through use of the keypad.</p> |
