Disclosed is a haptic feedback device used in an electronic device for providing haptic feedback. When the scanning START key is pressed while the device is in the logged-out state, the reading part reads a document and forms image data, and the storage part stores the image data formed by logged-out scanning in the shared space. Alternatively, the gaseous nitrogen source is one or more tanks of compressed nitrogen gas. The base region has a bottom face located on a same plane throughout the cell region and the peripheral region and provides an electric field relaxing layer located in the peripheral region. In one embodiment, spectral purity is achieved by providing a number of stages of up converting, expanding, and dividing down of an input signal. With the structure thus arranged, it is attempted to make the life of rollers longer, and to prevent the occurrence of double feeding of sheet material.
