The practical degree of green laser pointer is high enough

The laser technology of green laser pointer is relatively mature nowadays.
A step by step and thus reverse the direction of progress, the analysis of the heating signal transmission line. Found that this heating signal by the motherboard via an interface circuit to control the heating drum. To open the interface circuit box, and found that a simple control circuit board which can be broadly analysis of heating signal transmitted by the motherboard over. So that K1 (relay), then the heating voltage 120VAc K2 (K1 control) added to the heating coil of the drum. The heating coil total of three groups, each group of resistance for 3012. Visit with a multimeter the resistance to normal. Open the side panel of the drum and found inside a coin-sized thermal protection switch, thermal protection, when the drum temperature is too high heating signal to disconnect the main drum asked.  green laser pointer can control the pagedown and pageup of the PPT document in the computer.
Manufacturers or different models of laser camera scanning in different ways. Film developing rotary heating system: The system laser scanning film heated so that the developer, thus completing the developing, fixing, washing, drying of the wet laser camera automatic washing machine. Care and maintenance of the laser camera is either dry or wet laser imager, the manual provides maintenance instructions should be strictly in accordance with the requirements of the specification and careful operation. If the camera fails, the general processing in accordance with the fault tips; more complicated failure. Recommend to the manufacturers engineers and technicians repair. Wet Laser Camera. The engine room humidity should be maintained at about 20 ℃, and maintain proper ventilation and drying. The practical degree of green laser pointer  is high enough.
Open the camera back. Manual door control switch is closed. Visible seizure arm seizure action, the film can reach the film feed shaft. A film to enter the film to feed the region. Down to a film can not, and fall back to the film cartridge. Kodak sucker each draw two or more film in the fragmentation under the action of only one film feed shaft to enter the film feed area. The rest of the film fall back to the film cartridge. Analyze the causes fragmentation failure, the sorter is removed (using special tools such as no special tools to beware of the screws or screwdriver off the machine and increasing the workload). The examination revealed that the sorter is badly worn and deformed the urgent need to replace the sorter. Many star gazers would prefer to select green laser pointer for the star gazing.
