摘要：
A display apparatus used in automobiles has an indicating device mounted in the steering column to display the car running condition information and a reflecting plate installed in the dashboard to form a virtual image of displayed information at a point on the far side of the reflection surface from the driver. To make it more easy for the driver to see the displayed information, the apparatus incorporates a magnifying cylindrical lens which is installed between the indicating device and the reflection plate in such a way that the display surface of the indicating device is within the focal length of the lens. The virtual image of the displayed information is thus magnified by the lens and formed farther away from the driver's viewing point, making the displayed information more easily recognizable. Another feature of the apparatus is that the cylindrical lens can also be moved to a desired position to magnify the displayed information to any desired size for the driver.
