摘要： An image forming apparatus including a document-inlet, a multifunction opening, a document-outlet, a first document path and a second document path, is provided. The multifunction opening selectively functions as a document inlet or a document outlet. The first document path, responsive to the document fed in through the document-inlet, directs and drives the document from the document-inlet to the illumination/scan position, and, after the document is scanned, discharges the document to the multifunction opening. The second document path, responsive to the document fed in through the multifunction opening, directs and drives the document from the multifunction opening to the illumination/scan position, and, after the document is scanned, discharges the document to the document outlet. A section of the first document path and a section of the second document path overlaps to each other and defines an overlapping path.

摘要： An analog-to-digital conversion device and a method thereof are provided. The analog-to-digital conversion device includes a first level adjustment unit, an analog-to-digital converter (ADC), and a linear range detection unit. The ADC converts a test signal or a first input signal to generate a test data stream or a first output data stream. In an adjustment mode, the linear range detection unit obtains a conversion curve of the ADC by using the test data stream and determines whether to adjust offset control information according to a linear range of the conversion curve. In an operation mode, the linear range detection unit continues outputting the offset control information. Additionally, before transmitting the first input signal, the first level adjustment unit adjusts a direct-current level of the first input signal according to the offset control information to allow the first input signal to be within the linear range of the conversion curve.
