Design, holding handle 8 of stopping can be scanned, easy to use, and improve the comfort level of user.
The present apparatus use process is as follows：
The first step is scanned required content using the i.e. hand-held roller scanner of portable scanning device, photochopper
Use step with reference to above-mentioned；
Second step turns on the switch, and by hand held scanning device, it is horizontally placed on the top of required scanning area image, and manipulation makes it
Slowly glide；
Third walks, and when scanning means glides, the scanning ray that light source is released is projected through minute surface on paper, light-receiving
After device receives signal, data are handled, generate scanning figure；
4th step, when scanning means glides, the flyball 25 in speed-limiting device is due to inertia force foreign minister, when rotating speed is more than volume
When determining rotating speed, flyball 25 will reach the position mutually squeezed with brake-shoe 22, and then brake-shoe 22 is generated with 6 interior side contacts of idler wheel
Frictional resistance, in a certain range by the gliding speed limitation of scanning means；
5th step, scanning means reach sections bottom, are completed to the scanning work of entire scanning area.
