MEDIUM SEPARATION DEVICE OF ATM

摘要

The invention relates to a medium separation device of an automated teller machine (ATM) that includes a pickup roller for sequentially picking up and feeding stacked media through a friction member on a portion of the outer periphery of the pickup roller, a feed roller for feeding the picked-up and fed media toward a transfer path through a friction member provided on a portion of the outer periphery of the feed roller while rotating with the same phase as the pickup roller, and a medium separation unit for separating a following medium simultaneously fed with a preceding medium fed to the feed roller while in close contact with the bottom, from the preceding medium through a separation belt, to pick up and feed media through a partial roller structure partially having a friction member and simultaneously perform the separation of the media through the medium separation unit.

主权项

1. A medium separation device of an automated teller machine (ATM), which separates stacked media sheet by sheet and feeds them toward a transfer path, the medium separation device comprising:
a pickup roller disposed above the stacked media, the pickup roller having a first friction member provided to protrude from a portion of the outer periphery of a roller body so as to be contacted with the stacked media, the pickup roller sequentially picking up and feeding the stacked media by the first friction member according to the rotation of the roller body; a feed roller disposed to be spaced apart from the pickup roller in a medium feeding direction, the feed roller having a second friction member provided on a portion of the outer periphery of a roller body so as to be contacted with the fed media, the feed roller feeding the picked-up and fed media toward a transfer path through the second friction member while rotating with the same phase with the pickup roller; and a medium separation unit disposed below the feed roller, the medium separation unit having a plurality of separation rollers and a separation belt wound around the separation rollers, the medium separation unit separating a following medium, which is simultaneously fed while being in close contact with a preceding medium fed by the pickup roller and the feed roller, from the preceding medium through the friction of the separation belt.
