Image scaling device

An image scaling device, comprising:

• a housing including a main body member and a handle member, wherein the handle member extends outward from the main body member;
• a control unit located in the housing and including an image capture module, a display module, an image processing module and a micro switch module, wherein the image capture module is configured for capturing an image, and the micro switch module is located in the handle member and configured for generating a first signal and a second signal, so that the image processing module processes the image according to the first signal or the second signal to reduce or enlarge the image, so as to display the image reduced or enlarged by the image processing module on the display module;
• and
• a rotation unit arranged around the handle member and being able to rotate along a first rotation direction relative to the handle member to trigger the micro switch module to generate the first signal, and being able to rotate along a second rotation direction relative to the handle member to trigger the micro switch module to generate the second signal.
