<p><P>PROBLEM TO BE SOLVED: To solve the following problem: in use of a conventional one-sheet mirror, a driver must turn around in viewing a sideway or rearward image because the driver cannot look it at on the front side and, in use of two-sheet plane mirror or convex mirror, an image is vertically reversed on a rear view mirror or horizontally reversed on a side mirror. <P>SOLUTION: In obtaining an erected image using a minimum two sheets of mirrors, one mirror is installed toward a shooting position of a sideway or rearward image and the other is installed toward around driver's front side. The two sheets of mirrors are disposed to face each other in a dog-legged shape or an open angle shape, so that the driver can look at an erected image, paying attention to the focus of the mirror, for example, by inverting an image at the focus of a reflecting surface of the mirror. The mirrors are further curved to expand or contract the image for high visibility. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
