Claim 8:
9. A medium feeding mechanism comprising:
a feeder that feeds a medium;
a transport path that is coupled to the feeder;
a transporter that transports the medium through the transport path;
a transport drive that drives the transporter;
an entry detection sensor that detects when the medium fed from the feeder has entered the transport path;
a take-in transporter that takes in the medium transported by the transporter; and
a transport controller that controls the feeder and a destination controller that controls the take-in transporter, wherein
when the entry detection sensor detects entry of the medium at a time that falls within a first range set in advance, the destination controller controls the take-in transporter so as to take in the medium,
when the entry detection sensor detects entry of the medium at a time that falls within a second range following the first range, the transport controller controls the feeder so as to delay feeding of a medium to be transported next, and the transport controller is configured to communicate with the destination controller to instruct the destination controller to control the take-in transporter so as to delay a take-in time for the medium,
the feeder includes a placement mount on which media are placed, a floating-air blowout mechanism, including at least a fan, is configured to blow out floating air for floating at least an uppermost medium among the plurality of media placed on the placement mount, and a blocking part, including at least a shutter, configured to block the blowout of the floating air by the floating-air blowout mechanism, and
when the entry detection sensor detects entry of the medium at a time that falls within the second range, the transport controller causes the blocking part to block the blowout of the floating air.
