Description

Technical Field

[0001] The utility model relates to the technical field of a reading and writing telescopic imager, in particular to a reading and writing telescopic imager capable of adjusting the ciliary muscle. Background Art

[0002] Multimedia devices, especially video or image carriers, and even text carriers are widely used in people's daily lives, but excessive use will cause eye fatigue, and even worse, it will cause myopia, especially for adolescents and children, whose reduced vision has a huge impact on their daily lives.

[0003] For example, the telescopic display device with application number CN202320131828.5 places the display screen horizontally, keeps the beam splitter and the display screen at a 45° angle, and ensures that the concave surface of the free-form screen is arranged relative to the beam splitter, so that after the display screen is reflected by the beam splitter, its focus can fall on the optical axis of the free-form screen. The above arrangement ensures that the observer can observe a clear virtual image through the observation interface. In addition, placing the display screen horizontally can effectively avoid the situation where the observer cannot easily and directly see the display content of the display screen when observing, thereby reducing the interference of the display screen to the observer. In addition, the main board, driver board and other auxiliary modules are arranged in the gap formed between the optical module and the outer casing, which effectively saves space, improves space utilization and ensures the working performance of the telescopic display device.

[0004] The above-mentioned existing technical solutions have the following defects: the existing reading and writing telephoto imagers can only display images at a specific distance, resulting in the inability to adjust the entire display according to the specific circumstances of the user, and long-term viewing at the same viewing distance will cause visual fatigue and adjustment problems for the ciliary muscles of the eyes, which will deepen myopia and reduce the overall protection effect on the user's eyes.

[0010] The lower end of the image display box is fixedly connected with an illumination lamp, and the illumination lamps are arranged in multiple groups at equal intervals at the lower end of the image display box.

[0011] The fixing bracket is internally threaded with a positioning screw, the lower end of the positioning screw is fixedly connected to a fixing suction cup, a placement groove for placing the fixing suction cup is provided at the bottom of the fixing bracket, and the positioning screw passes through the upper end of the fixing bracket and extends into the placement groove.

[0012] The positioning screws are distributed correspondingly to the fixed suction cups, the length and width of the placement grooves are greater than the maximum diameter of the fixed suction cups, and the fixed suction cups and the placement grooves are distributed correspondingly at equal intervals inside the fixed bracket.

[0013] In summary, the beneficial technical effects of the utility model are:
