It is more than a camera or scanner. It provides an opportunity to create your own library which is as simple as an earser. This is a camera without any sound or light and simple to use. It uses the least possible material. People can transfer all documents to Muji Library easily and save more paper.
Every camera has a viewfinder. People always look really close to that tiny hole to take photos. Muji is not only simple from outside but also simple to use. Therefore the relationship between paper and camera is an important aspect to consider.
The size of camera is 37mmx52.5mm as the proportation of a piece of A4 paper. The whole camera can become a viewfinder. The distance between camera and paper can be changed due to the different size of paper.
