<p>A display unit having a display memory property is constituted to be detachable from an attaching/detaching mechanism provided on a drive circuit substrate, so as to be attached to the attaching/detaching mechanism of the drive circuit substrate for rewrite of display information, and detached from the attaching/detaching mechanism of the drive circuit substrate after rewrite and moved to elsewhere while maintaining information displayed. Moreover, since it is constituted such that an actuation driver, having an expensive IC is mounted thereon, can be replaced rather than to be discarded or a drive circuit substrate can be replaced rather than to be discarded in a case where the display unit for displaying information such as an image causes a failure, it thereby achieves improvement of resource use efficiency by reusing the actuation driver having the expensive IC mounted thereon or the drive circuit substrate.</p> |
