Abstract
A sheet sensing module and a duplex scanning apparatus having the sheet sensing module are provided. The sheet sensing module includes a first sensing arm, a second sensing arm, and an electronic sensor. The first sensing arm is partially exposed to a sheet feeding channel of the duplex scanning apparatus. The second sensing arm is partially exposed to an inverting channel of the duplex scanning apparatus. When a document is transferred through the sheet feeding channel to trigger said first sensing arm or the document is transferred through the inverting channel to trigger the second sensing arm, the electronic sensor generates a sensing signal.
