Abstract: A structure of light box assembly is disclosed in the invention, which includes an upper plastic frame and a lower plastic frame, and each of them can be formed by a plastic sheet or two same plastic sheets. Besides, at least four supporting columns are used to connect and support the two plastic frames. In addition, a plurality of side plate, an upper cover plate, and a lower cover plates are separately installed according to different planes formed by each of the plastic frames and each of the supporting columns so as to construct a box body. Also, an erect diffusion plate is provided at each corner of the box body corresponding to the position of its relative supporting column so that each of the four diffusion plates is to cover the outer field of each of the vertical light tubes. Thus, uniformly distributed light can be provided, and a solid and uniform light source can be provided as well.
Abstract: A uniform radiation intensity generation box using a symmetrical lighting source is constructed to include a housing, the housing having a top opening for the mounting of a camera for taking photos of a real object and a door at one side, a plurality of lamp tubes vertically symmetrically provided inside the housing, and a plurality of diffusion plates mounted inside the housing and covered over the lamp tubes, each diffusion plate having a plurality of diffusing grains uniformly arranged in one face thereof and adapted for diffusing light from the lamp tubes in all directions inside the housing.

Abstract: The present invention discloses a network scan control apparatus connected to a server computer of a network through a computer interface for transmitting, in a push model, an image scan data obtained by an image scanner to a client computer on the network. The network scan control apparatus comprises a computer interface controller and a user interface connected to the computer interface controller. The user interface is provided with an input/output device for inputting instructions and data and displaying messages. The network scan control apparatus further comprises a scan area select mechanism connected to the computer interface controller for selecting an area of a document to be scanned. The present invention enables sharing of an image scanner on a network and enhances resource utilization of the image scanner.
