Scanning method of scanning apparatus and scanning apparatus

A scanning method of scanning apparatus being a sheet-fed scanning apparatus having a reflective document scanning function and a transmissive document scanning function, wherein the scanning method comprises the following steps:

• activating the scanning apparatus which is in a default reflective document scanning state;
• sensing by the scanning apparatus to determine whether a document holder is disposed in a feeding entrance;
• If there is no document holder inserted into the feeding entrance, the scanning apparatus is determined as the reflective document scanning state, and when the scanning apparatus obtains a sensing signal indicating that the document is already fed in, the scanning apparatus activates a reflective document scanning element to perform the reflective document scanning function;
• automatically setting the scanning apparatus to be in the transmissive document scanning state if there is a document holder inserted into the feeding entrance, wherein when the scanning apparatus obtains the sensing signal indicating that the document is already fed in, the scanning apparatus activates a transmissive document scanning element to perform transmissive document scanning function.

A scanning apparatus having a reflective document scanning element and a transmissive document scanning element, wherein the scanning apparatus comprises:

• a set of feeding assembly comprising a plurality of feeding rollers and corresponding driven rollers;
• a document holder whose one end has a transmissive document insertion portion and the other end has a hard insertion end;
• an activating mechanism disposed at one side of the feeding assembly;
• wherein, when the document holder is not inserted into the feeding assembly, the scanning apparatus is in a reflective document scanning state, and after the hard insertion end of the document holder is disposed in the feeding assembly, the document holder activates the activating mechanism for enabling the scanning apparatus to activate a transmissive document scanning function.
