摘要： A light sensing apparatus includes a sheet passage, a first sensing assembly and a first background sheet. The sheet passage has a scan window. The first sensing assembly disposed on a first side of the scan window outputs first scan light to the scan window. The first background sheet disposed on a second side of the scan window has a first reflective surface reflecting the first scan light, passing through the scan window, back to the first sensing assembly through the scan window. The first reflective surface of the first background sheet and the scan window are disposed in a non-parallel manner. Therefore, a light sensing method is also provided to achieve the effects of brightness calibration and boundary detection of the first sensing assembly.

摘要： A scanning device comprises a visible light source, an infrared light source, a visible light sensor and an infrared light sensor. The visible light source provides visible light to a scan section of an original. The original reflects the visible light to generate reflected light. The infrared light source provides infrared light to the scan section. The infrared light penetrates through the original to generate penetrating light. The visible light sensor receives the reflected light at a first scan position and generates a visible light image signal representative of a visible light image of the scan section. The infrared light sensor receives the penetrating light at a second scan position and generates an infrared light image signal representative of an infrared light image of the scan section. A relative positional relationship between the first and second scan positions is fixed. A scanning method for the scanning device is also provided.

摘要： According to one embodiment, a document detecting apparatus includes a light-emitting element, a photoelectric conversion element, a light-emission controller and a detection processor. The light-emitting element projects light onto a detection position of a document. The light-emitting element is not used for reading an image of the document. The photoelectric conversion element converts light projected onto the detection position into an electric signal and outputs the electric signal. The light-emission controller changes the light quantity of the light emitted by the light-emitting element during a predetermined interval. The detection processor detects the presence or absence of the document at the detection position of the document based on whether a value of the output electric signal during the predetermined interval changes in correspondence to the change of the light quantity caused by the light-emission controller.

摘要： An image reading device includes a platen glass, a document feeder, a light source, a light receiving section, a first opening/closing detection sensor, a second opening/closing detection sensor, and a document size determination section. The document size determination section determines a size of an original document on the basis of a measurement result from the light receiving section. Where the first opening/closing detection sensor indicates the open state, while the second opening/closing detection sensor indicates no open state when the original document is placed on the platen glass, the document size determination section determines a size of the original document in a main scanning direction on the basis of full lighting-up determination data obtained with all of plural light emitting elements lighted up and partial lighting-up determination data obtained with some of the plural light emitting elements lighted up.

摘要： A paper size detection device includes a central switch, at least two switches disposed to two opposite sides of the central switch at intervals, and at least a sensor corresponding to the two switches located at the two opposite sides of the central switch. The sensor can be designated as a light sensor. One switch triggers the sensor and the other switch is without triggering the sensor under an original no paper condition. So that a detection method of the paper size detection device that uses N light sensors to judge N*2 papers' size can be realized by virtue of the above-mentioned setting structure, N is a positive integer, such as 2, 3, 4 and so on. Thus, the paper size detection device has a simple structure and a lower manufacture cost, and the detection method of the paper size detection device is simplified, accordingly.
