Abstract
Abstract A combination meter has a plurality of indicators for respectively indicating different measured amounts, in which an indicating area is reduced so as to achieve a compact design. Pointers of indicators are formed respectively by light transmitting slits provided respectively on disks. The disks are rotatably mounted in a laminated manner on a shaft concentric with these disks, and the disks are angularly moved respectively by drive sources in accordance with respective measured amounts.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
122 words
A combination meter, comprising: a dial plate including light transmitting portions and scale portions corresponding to different operating parameters; light means for illuminating a rear side of said dial plate; a shaft protruding for ma front side of said dial plate; a plurality of disks rotatably provided on said shaft in an overlapping manner, each of said disks including a light transmitting pointer portion; and operating means for individually and independently rotating said disks in response to respective measured parameters such that the respective pointer portions point to corresponding values on said corresponding scale portions, wherein light emitted from said light means is transmitted through said light transmitting portion of said dial plate and said light transmitting pointer portions of said disks.
Claim 2
Dependent Claim
122 words
A combination meter, comprising: a dial plate including light transmitting portions and scale portions corresponding to different operating parameters; light means for illuminating a rear side of said dial plate; a shaft protruding for ma front side of said dial plate; a plurality of disks rotatably provided on said shaft in an overlapping manner, each of said disks including a light transmitting pointer portion; and operating means for individually and independently rotating said disks in response to respective measured parameters such that the respective pointer portions point to corresponding values on said corresponding scale portions, wherein light emitted from said light means is transmitted through said light transmitting portion of said dial plate and said light transmitting pointer portions of said disks.
Claim 3
Dependent Claim
20 words
