ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a scanning system, and more specifically, to a scanning system with retractable image capturing device.
BACKGROUND OF THE INVENTION
The scanning system is a image processing tool popularly employed for scanning the image of documents, photographs, and even objects. The image is transferred to accessible signal or data for the computer. The document is illuminated by a light source during scanning. The image is then transferred upon a CCD (Charge-Coupled Device) set through a set of lenses or a CIS (Contact Image Sensor) set. The CCD set or the CIS set transforms the image to accessible signals. In general, the scanning systems can generally classified into three categories, including a handhold scanning system, a sheet feeding scanning system, and a flatbed scanning system.
For receiving large enough documents like eight and a half inch wide A4 document, conventional scanning system is big in volume and occupies a large space. The space occupied is even larger especially for the flatbed scanning system. Most of the scanning system is an isolated peripheral device to a computer system. The isolated device makes it an inefficient peripheral in space and inconvenient to use. In recent years, a scanning system which can be incorporated or integrated with a desktop computer, a laptop computer, or other peripherals like monitors, printers, or keyboards are developed to save more space.
The sheet feeding scanning system is one of the most space-efficient system. The conventional sheet feeding scaring system has a paper guide or a tray for feeding or placing a document. The scanning system with a paper guide generally cost additional volume space for the large volume of the paper guide. The open design of the scanning system suffers the pollution problem of dust and particles and the image quality is influenced. Some of the system use only rollers without paper guide to save more space. However, the system without a paper guide is not convenient to use and cause the problem of tilted document feeding. In the scanning system with a tray for place documents, the complicate mechanical construction makes it hard to design and manufacture. The maximum acceptable length of the documents is also limited with the limited tray size.
SUMMARY OF THE INVENTION
The present invention discloses a scanning system with a retractable image capturing device. The image capturing device can be retract from the scanning system for feeding and scanning a document. The image capturing device can be received within the scanning system when not in use. The space inefficiency of the conventional scanning system can be eliminated. The scanning system can be kept from the pollution of dust and particles. The image capturing device can be kept clean and the image quality can be maintained. The problem of the length limitation in the traditional tray system is also removed.
The scanning system with a retractable scanning portion in the present invention includes a frame and an image capturing device. The frame provides a space for receiving parts of the scanning system. The image capturing device is retractably mounted within the frame. The scanning system can further includes means for guiding a document into the image capturing device. Means for retracting the image capturing device from the frame can also be added.
The document guiding means can be a foldable paper guide which is attached with the image capturing device and can be received into the frame with the image capturing device. In addition, the foldable paper guide has a pair of sildable guiding keys which are mounted on the foldable paper guide and slidably in parallel with a document front. The scanning system can be mounted to a computer, a keyboard, a monitor, or a printer by the frame.
