INSTRUCTIONS: TECHNICAL FIELD OF THE INVENTION The present invention relates to computer workstations, and more particularly to a computer workstation that can adjust the VDT workspace to the user's body size. 5 [Prior technology] The development of k-ball digitalization has evolved, and the visual display terminal (VisUai Display Terminals; hereinafter referred to as VDT) has become one of the necessary requirements for inauguration, in order to obtain the best work efficiency and reduce the long-term VDT operation. Cumulative discomfort, erg〇n〇mic engineer plays a key role in the design of the vdt phase 10 equipment. The design of the computer workstation is designed to reduce the hazards of the work, and the user interface is measured through the human body. The adjustment parameters of the computer maintenance station used in the design are as follows: 1 · The working surface south degree: The working surface height is generally based on the user's sitting elbow height, and the scholar 15 research indicates that the user adopts a relaxed posture. The upper arm and the elbow are about 90 degrees for the wr. 'Helps to pour the red straightness. The best comfortable operation month & the position of the computer workstation working surface recommended by the research institutes, all based on the elbow height. Make set standards. 2. Screen height: 20 i screen two summer 疋 finger ί electric articles - firefly - curtain - center is τ also board is lacking I blue, ... firefly position, at least 15 degrees below the line of sight, the top edge of the camp Below the eye 7 leveling 'adjustable work table or screen is better. When the operation is performed, the viewing distance of the user's eyes to the center of the screen can be defined as the line of sight (v黯mg stance). In terms of VDT operation, the line of sight of % cm is better than that of 4 200806913 i〇〇a knife. The distance is more likely to cause visual fatigue. The line of sight should be matched with the size of the screen. The optimum line of sight of the vDT should be set to between centimeters. The right fork is facing the screen and the arm is straightened horizontally, about one arm. The distance ^ is the best line of sight. The line-of-sightsight (line-of.sightangle) is the angle between the horizontal south of the eye 5 and the line connecting the eye to the center of the screen. The position of the computer screen should be between 15 and 25 degrees below the horizontal line of the eye, and the angle of sight is the lowest and should not exceed 30 degrees ' and make the screen and sight line 9 () degrees, that is, the front of the screen should be slightly up. VDT related research pointed out that the line of sight angle 1〇 is defined as the reward screen position (high_monitor position; hereinafter referred to as HMP) and the 10-line angle 30 degrees is defined as the low screen position ( (5) (10) as (4) out (10): hereinafter referred to as LMP) The electromyogram of the neck and shoulder of the HMP (Electr〇my〇gram • hereinafter referred to as EMG) is significantly lower than that of the LMp, showing the difference in the eye and the neck-shoulder response. In the cone of 15 degrees below the line of sight, the eyeball can In addition, the study also pointed out that in the case of LMP, the eyelids cover more parts of the eyeball and can reduce the dryness of the eyes. Therefore, the study suggests 1^1卩, but most of the recommendations for musculoskeletal still regard HMP. It is better. 3. Working surface: The area setting of the working surface depends on the difference between the objects and working type that the VDT user may display (for example: VDT operation for writing and flipping data), 2) design sound requirements - for the appropriate side In order to accommodate the location of the book, in addition to the screen 'printer and host size, etc. are also included in the space design plan. The layout of the work surface must be compatible with different types of VDT operations, and the computer peripherals that may be used are planned. Therefore, the design must be matched with the work type to achieve the best results. 5 200806913 4·Screen size: The user prefers the female visual surface area to increase, and the screen is too large. However, the screen is too large to cause the user to easily cause neck and shoulders, and the skin is too tired, but the VED operation is too small. ^strong's research suggests that 19 pairs of screens are most suitable. 5. Keyboard position: V〇T operation is the most. According to the 9241 standard, the input device for 1 is keyboard and mouse, ISO 188mm.手The palm support space required when using the keyboard is at least 6. The position of the mouse: The part is made to make the hand f and the forearm in a straight line' and try to make the movement of the hand, the bud is given, and the upper arm should not be stretched when the mouse is used as a mouse. Or bend to bend and cause the position to be straight, so that the structure of the carpal nerve and the vascular not 15 C workstation mainly includes - table, - display frame ancient master Ke, wherein the seat or the display frame can cooperate with the user = Further adjustments to achieve the purpose of reducing the hazard of the work; however, the conventional power = workstation can only provide the height of the adjustment display stand or seat, but can not provide the appropriate working space configuration for the VDT operation. The location is not universal and cannot meet the six parameters of the aforementioned requirements and needs to be improved. SUMMARY OF THE INVENTION The main object of the present invention is to provide a computer workstation having 20 200806913 which provides users with the characteristics of optimal position adjustment of computer related equipment. To achieve the above object, a computer workstation for carrying a computer related device for visual display terminal (VDT) operation includes a bracket and a plurality of carriers, each of the carriers having an extension arm and a carrier plate, the extension 5 One end of the arm is pivotally disposed on the bracket and vertically displaceable along the bracket, and is rotatable relative to the bracket, and the carrier is disposed at an outer end of the extension arm, and can carry computer related equipment thereon; thereby, the present invention Moving the carriers vertically to adjust the height of the carriers relative to the user, and by rotating the carriers to adjust the distance of the carriers relative to the user, so that the computer related equipment can be arranged at The best position to match the size of the user's body. [Embodiment] In order to explain the structure, features and effects of the present invention in detail, the following description of the preferred embodiment and the accompanying drawings are as follows: 15 - Please refer to the first to third figures, which are computer workstations of the present invention The first preferred embodiment of (10) is applied to a computer-related device such as a screen, a keyboard, a mouse, and a printer. The computer workstation (10) includes a bracket and a four-carrier (30). The bracket (2〇) has an upright rod (9) and a tripod (10) disposed at the upright 20 rod end. The erect Zen and the right dry ring groove (26) are perpendicular to the long groove (four). The stand (10) is opposite to the upright rod (21)_ for supporting the upright rod (21) so that the money stands straight on the ground. The long groove (24) extends along the long axis direction of the upright rod (21), and the annular groove (26) is perpendicular to the long groove (24) and spaced apart by a predetermined distance, and is in communication with the long groove (4) 200806913. Each of the carriers (30) has an extension arm (32) and a carrier plate (34); wherein the extension arm (32) has a connection portion (321) and a bolt member (322). The connecting portion (321) is a tube body that can be sleeved on the upright rod (21) and can be displaced and rotated along the upright rod (21). The bolt (322) is a bolt and is threaded through one of the screw holes of the connecting portion (321). The bolt (322) is movable in the long groove (24) and the annular groove (26).
