<p>PURPOSE:To shrink the space of a conveying device by providing an exciting means to move the second conveying unit by an appropriate quantity when the first conveying unit is opened. CONSTITUTION:When the first upper conveying unit 20 is opened and the contact between a pin 20e and a protruded member 30c is released, the second conveying unit 30 is pushed by the elastic member 40a of a damper 40 and moved upward to the open side. In this case, the second conveying unit 30 is lifted to the position where the excitation force of a spring 40d and the tare weight of the second conveying unit 30 are balanced. When the compression spring 40d with a proper spring constant is selected, the motion of the second conveying unit 30 can be made an adequate quantity, thereby the second conveying unit 30 can be opened with its tip section 30d via a gap generated at the lower section of the tip section 30d of the second conveying unit 30 without providing a special knob to open the second conveying unit 30.</p> |
