Abstract: A scanning device comprises a light source, a reflecting mirror and a photosensor. The light source provides light to an original. A first portion of the light penetrates through a hole of the original and becomes penetrating light. A second portion of the light is reflected by a hole-free portion of the original and becomes second reflected light. The reflecting mirror reflects the penetrating light and generates first reflected light. The photosensor receives the first reflected light and the second reflected light and generates a hole-containing image signal representative of an image of the original.

Abstract: A multi-mode scanning device includes a background element, a transparent platen, first and second light sources and an optical module. The first light source outputs visible light to irradiate the background element and an original on the transparent platen to generate first and second light, respectively. The second light source outputs invisible light to irradiate a combination of the background element and the original to generate third and fourth light. The movable optical module receives the first to fourth light and generates sensing signals, and obtains visible light information and invisible light information representative of the original according to the sensing signals. The original is disposed between the background element and the optical module. The first light source and the optical module are disposed on a same side of the background element. The optical module and the second light source are disposed on different sides of the background element.

Abstract: An information security management system and a multifunction printer thereof are provided. The multifunction printer includes an image capturing module, an image processing module, an output module and a transmission module. The image capturing module captures a data image of a document paper. The image processing module is coupled to the image capturing module and encodes the data image to generate first encoded data. The output module is coupled to the image processing module and prints second encoded data related to the data image. The transmission module is coupled to the image processing module and transmits one of the first and second encoded data. The multifunction printer deletes the first encoded data from a memory after transmitting the first encoded data, and deletes the second encoded data from the memory after transmitting/outputting the second encoded data.

Abstract: A rotary encoder includes a rotating shaft, first and second encoder wheels, first and second detectors and a processor. The first encoder wheel includes coaxially disposed first and second portions. The first portion has first graduation features. The second portion has a first positioning structure. The second encoder wheel includes coaxially disposed third and fourth portions. The third portion has second graduation features. The fourth portion has a second positioning structure meshing with the first positioning structure, so that the first graduation features and the second graduation features are staggered, and the first encoder wheel and the second encoder wheel are coaxially mounted on the rotating shaft. The first and second detectors detect the first and second graduation features and output first and second signals, respectively. The processor calculates a rotating angle of the rotating shaft according to the first and second signals.

Abstract: A printing head and a method for applying a correction for mounting deviation of light-emitting chips are provided. The printing head includes a plurality of light-emitting chips. Each light-emitting chip includes a plurality of primary light-emitting elements that are continuously arranged. At least one of two adjacent light-emitting chips further includes at least one spare light-emitting element continuously and linearly arranged after the primary light-emitting elements. If the two adjacent light-emitting chips are both at a target mounting position, first N light-emitting units of one of the two light-emitting chips respectively face to first N light-emitting units of the other one of the two light-emitting chips, where N≥1. Each two of the light-emitting units facing to each other form a group. One of the two light-emitting units in each of the groups is set to a light emission disabled state.

Abstract: A scanning device includes 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.

Abstract: An image sensing device includes N red light sensing units, N green light sensing units, N blue light sensing units and a control circuit. The control circuit accumulates an exposure capacity Qi generated by the ith red light sensing unit, green light sensing unit, and blue light sensing unit in an exposure time Ti and an exposure capacity Qi+1 generated by the (i+1)th red light sensing unit, green light sensing unit, and blue light sensing unit in next exposure time Ti+1 until an exposure capacity QN generated in the TNth exposure time is accumulated, wherein i is an integer ranging from 1 to N. The exposure capacities Qi to QN are sequentially stored in a register and outputted from the control circuit, so that the image of each scan line can be sequentially transferred to an analog signal with the sum of the exposure capacities Qi to QN.
