Ruler is a kind of widely used stationery. However, traditional rulers have lots of drawbacks and inconveniences
.
A canon ruler can make it possible to draw rather long straight lines in an elegant way while being portable in size itself as well.To draw a long straight line, use the main part first,then fix the main part using one hand and pull out the attached black part with the other hand,keep the Attached part stable this time and take back the main part to continue the drawing.Repeat these steps when necessary,just like the trick in Canon.
Besides,a canon ruler can also be used to measure long objects thanks to its unique structure.
