Abstract
The utility model discloses a changeable dimming X-ray film reader, which comprises a base and a frame body installed on the base, wherein a frame of the frame body is provided with a light-transmitting panel and an LED backlight light source. The frame body is provided with a dimming device which comprises a dimmer driving motor, a dimming film and rollers, wherein the rollers are arranged at the upper and lower ends of the frame body, roller ends are movably connected with the frame body, and one of the rollers is connected with the driving motor; the dimming film is circularly sleeved between the two rollers, and the dimming film is divided into a full light-transmitting area, half light-transmitting area and a gradual light-changing area. The changeable dimming X-ray film reader is used for reading X-ray films. The dimming film can be controlled to move a certain position by using the driving motor when the changeable dimming X-ray film reader is used, the dimming film between the light-transmitting panel and the LED backlight light source is enabled to be adjusted to an appropriate light-transmitting area, and then the required light-transmitting intensity and area are obtained on the panel, thereby realizing dimming. The position of the dimming film can be adjusted by using the driving motor at any time according to requirements of different films and areas, thereby being convenient to use.
Description
Technical field
The utility model belongs to medical X-ray and reads the sheet devices technical field, especially relates to a kind of X-ray that can light modulation and reads the sheet device.
Background technology
At present, in clinical diagnosis, the status of film in Medical Imaging still has critical positions.It is affected by environment larger that radiodiagnosis is read sheet, there are some researches prove the increase along with diagnostic environment brightness, to the also decline thereupon of Detection capability of image detail.Existing generally use read the sheet lamp, often covet giant-screen and high brightness, but without masked apparatus, the negativ-effect light that produces when the film observed less than its film viewing screen can cause signal (focus) read rate to descend, not only use inconvenience, and affect diagnosis effect.
Summary of the invention
The technical problems to be solved in the utility model be to provide a kind of can be according to film size, what facilitate adjusting backlight luminance and printing opacity size reads the sheet device.
For solving the problems of the technologies described above, the utility model comprises base and the support body that is arranged on base, the frame-saw of support body is provided with light penetrating panel and LED-backlit light source, its design feature is that support body is provided with light modulating device, described light modulating device comprises light modulation drive motor, light modulation film and transfer roller, transfer roller is arranged on the support body upper and lower end, and transfer roller termination and support body are flexibly connected, and one of them transfer roller is connected with drive motor; Light modulation film is sleeved between two transfer rollers in the form of a ring, and light modulation film is divided into the full photic zone that joins successively, semi-opaque region and gradual change light district.
Described semi-opaque region is divided into full impregnated and the full two parts that hide, and wherein the full impregnated zone is positioned at the middle part of semi-opaque region.
Described LED-backlit light source is board-like LED-backlit light source.
Described transfer roller is 3, is the triangle setting, and the support body upper and lower end is respectively equipped with a transfer roller, and the base tail end is provided with a transfer roller, and described light modulation film is socketed between each transfer roller in the form of a ring.
After adopting said structure, because the utility model is provided with light modulating device, light modulating device is provided with light modulation drive motor, light modulation film and transfer roller, and light modulation film is divided into full photic zone, semi-opaque region and gradual change light three, district zones of different.Can utilize drive motor to control light modulation film during use and turn to certain position, make the light modulation film between light penetrating panel and LED-backlit light source transfer to suitable transmission region, and then obtain needed penetrating light intensity and area on panel, realize light modulation.The light modulation film position can utilize the drive motor adjustment at any time according to the needs in different films or zone, and is easy to use.
Description of drawings
Below in conjunction with drawings and Examples, the utility model is further described:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation that Fig. 1 right side is looked;
Fig. 3 is that the utility model light modulation film launches schematic diagram.
Embodiment
With reference to accompanying drawing, this changeable light modulation X-ray is read the sheet device and is comprised base 10 and the rectangle support body 1 that is arranged on base 10.Be fixed with plastic light-transmission panel 2 and LED-backlit light source 7 on the frame-saw of support body 1, LED-backlit light source 7 is board-like white light source, and base 10 is provided with LED light source driver 9, attaching plug 5, and support body 1 front is provided with power switch.Support body 1 is provided with light modulating device, this light modulating device comprises light modulation drive motor 4, light modulation film 6 and transfer roller 8, transfer roller 8 is 3,3 transfer rollers 8 are the triangle setting, are respectively equipped with a transfer roller 8 at support body 1 upper and lower end, and transfer roller 8 terminations and support body 1 are flexibly connected, the transfer roller on top is connected with drive motor 4, base 10 tail ends are provided with a transfer roller, and light modulation film 6 is socketed between each transfer roller 8 in the form of a ring, and join with the transfer roller rolling.Light modulation film 6 is divided into the full photic zone 61 that joins successively, semi-opaque region 62 and gradual change light district 63, semi-opaque region 62 also is divided into full impregnated light and the full two parts that hide, full impregnated wherein partly is isosceles triangle, and being arrow shaped along full photic zone 61 directions at semi-opaque region 62 zone lines extends, the full part that hides is the full impregnated partial-length direction both sides that symmetrical right-angle triangle is arranged on isosceles triangle shape, gradual change light district 63 serves as reasons dimmed, or is thoroughly gradually changed by dark change.Turn on the power switch, drive motor 4 can drive transfer roller 8 rotations that are attached thereto, and makes light modulation film 6 go to certain position, just can utilize the part light modulation film 6 of 7 of light penetrating panel 2 and LED-backlit light sources to carry out light modulation.Be provided with piece pressing clip 3 at support body 1 top, front.
