  • Patent number: 6824010
    Abstract: A selective actuating apparatus involves a barrel 17 rotated due to rotation of a driving motor 2, a revolving shaft 3A supporting rotatably the barrel 17, and a barrel 16 rotated as a result of transmitting torque in the case where the barrel 17 is rotated in a direction b indicated by an arrow wherein a cam section 16B is defined on the barrel 16. In this condition, when the barrel 17 rotates in a direction a indicated by an arrow, the torque does not transmit to the barrel 16, but the barrel 16 is allowed to displace along the revolving shaft 3A due to sliding motion in between a projection 16A formed on the barrel 16 and a projection 17D formed on the inner circumference of the barrel 17 in a stepped manner. As a result, the selective actuating apparatus by which a plurality of driving objects can be driven without requiring a plurality of driving sources, so that its driving system can be downsized is obtained.

  • Patent number: 6397904
    Abstract: A link (20) is moved to a perpendicular (upper) direction based on a driving force F and a pin (22) provided on a link (16A) is moved along a guide groove (23) to a position shown in FIG. 5. Since the link (16A) is pivotally connected to a supporting unit (15) by a pin (14), the pin (22) can be moved along the guide groove (23) to a horizontal direction shown by an arrow without any change of its perpendicular position. By the movement to the horizontal direction, a clockwise rotating power around the pin (14) is generated in the link (16A). According to the cup type automatic vending machine of the invention, a cup transport mechanism can be driven by a small driving force, and the vending machine can be smaller without any deformation and circulation incapability of cups.
