Abstract

PROBLEM TO BE SOLVED: To improve visibility by disposing a lens which enlarges and displays a second display. SOLUTION: The housing 8 houses a speed meter, a rotation meter (each as a first displaying instrument), and a fuel meter, a water thermometer and a liquid crystal display device 12 (each as a second displaying instrument). A liquid crystal display instrument 12 is disposed above the fuel meter and the water thermometer. The speed meter and the rotation meter are larger than the fuel meter and the water thermometer, and the fuel meter and the water thermometer are disposed between the speed meter and the rotation meter. A protective cover 21 consists of a light-transmitting resin and has lens portions 22, 24 formed at the position corresponding to the fuel meter, water thermometer and liquid crystal display instrument 12. The lens portion 22 is a convex lens with a circular front view, while the lens portion 24 is a convex lens with an almost rectangular front view. The cover is formed to have almost uniform thickness in the portion corresponding to the speed meter and rotation meter. Thereby, the fuel meter, water thermometer and liquid crystal instrument 12 can be displayed as enlarged to improve the visibility.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the present invention is applied to a vehicle display device will be described below with reference to the accompanying drawings.
Reference numeral 8 denotes a housing. The housing 8 includes a front housing 9 and a rear housing 10. The housing 8 has four indicating instruments 11, that is, a speedometer 11a.
(A first indicator), a fuel gauge 11b (a second indicator), a water temperature gauge 11c (a second indicator), and a tachometer 11d (a first indicator) are housed therein. Speedometer 11a and tachometer 11
d is larger than the fuel gauge 11b and the water thermometer 11c, and the fuel gauge 11b and the water thermometer 11c are arranged between the speedometer 11a and the tachometer 11d. A liquid crystal display 12 (second display) is housed in the housing 8, and is disposed above the fuel gauge 11b and the water temperature gauge 11c.

The indicating instrument 11 includes a dial 13 and a cold cathode tube 1.
4, light guide member 15, pointer 16, stepping motor 17
And a circuit board 18. The cold cathode tube 14 and the light guide member 15 are arranged behind the dial 13, and the indicator 19 of the dial 13 is transmitted and illuminated by the light of the cold cathode tube 14. The pointer 16 is rotated by a stepping motor 17 to indicate an indicator 19 on the dial 13. Cold cathode tube 14
Is guided to the pointer 16 by the light guide member 15, and the pointer 16
Is illuminated. The liquid crystal display 12 is of a TFT (thin film transistor) type in which a number of pixels are arranged,
Displays route guidance information and the like.

Reference numeral 21 denotes a protective cover, which is locked to the front housing 9 by locking claws.
