Medium overlapped-feed preventing mechanism and medium sending-out device

摘要

A medium overlapped-feed preventing may include a feed roller which is structured to abut with the information recording medium and carry the information recording medium; a separation roller oppositely disposed to the feed roller and is urged toward the feed roller and is rotated in the same direction as the feed roller for separating overlapped information recording media which are carried in an overlapped-feed state; and a gate mechanism provided with a gate part through which one piece of the information recording medium is capable of being passed but two pieces of the information recording medium in an overlapped state are unable to be passed. The gate part may disposed on a downstream side in a sending-out direction of the information recording medium with respect to an imaginary line which is formed by connecting a rotation center of the feed roller with a rotation center of the separation roller.

1. A medium overlapped-feed preventing mechanism structured to send out an information recording medium one at a time in a state that a plurality of information recording media is overlapped, comprising:
a feed roller which is structured to abut with the information recording medium and carry the information recording medium; a separation roller which is oppositely disposed to the feed roller and is urged toward the feed roller and is rotated in the same direction as the feed roller for separating overlapped information recording media which are carried in an overlapped-feed state; and a gate mechanism provided with a gate part through which one piece of the information recording medium is capable of being passed but two pieces of the information recording medium in an overlapped state are unable to be passed; wherein the gate part is disposed on a downstream side in a sending-out direction of the information recording medium with respect to an imaginary line which is formed by connecting a rotation center of the feed roller with a rotation center of the separation roller; and wherein the gate part is structured of a first gate part and a second gate part which are oppositely disposed to each other in a thickness direction of the information recording medium, the first gate part is disposed on a separation roller side and the second gate part is disposed on a feed roller side, and the second gate part is formed so as to extend to an anti-sending-out direction which is an opposite direction to a sending-out direction with respect to the first gate part.
