Paper slip transport and stack unit

A paper slip transport and stack unit, including a stack section having a casing for storing slips of paper, for transporting slips of paper to the stack section and storing them in the stack section in a state in which a given number of slips of paper are stacked up, said unit comprising:

• means for separating received slips of paper into individual slips;
• means for transporting the separated slips of paper to said stack section;
• means for counting the slips of paper being transported;
• paper slip lift means, installed in said stack section for stacking slips of paper, for pushing up a selected number of the stacked slips of paper to an inside of the casing from a downward position for storing the slips of paper in said stack section;
• a single drive source capable of outputting driving forces for driving said separation means, said transport means, and said paper slip lift means selectively in both forward and reverse directions;
• and
• power transmission means for transmitting the driving force output from said drive source to said separation means, said transport means, and said paper slip lift means separately,
• said power transmission means comprising
• a first transmission mechanism, operative when said drive source outputs a first driving force in a forward direction, for receiving the first driving force and transmitting it to said transport means;
• a second transmission mechanism, operative when said drive source outputs a second driving force in a reverse direction, for receiving the second driving force and transmitting it to said paper slip lift means;
• and
• a third transmission mechanism, operative when said drive source outputs a third driving force in one of a forward direction or a reverse direction, for receiving and transmitting the third driving force in said one of a forward direction or a reverse direction and transmitting the same to said separation means.
