  • Patent number: 7619211
    Abstract: LED elements (5) which are light emitting elements are mounted on a substrate (7). LED light guide plates (9, 9) which are light-emitting-element light guide components are arranged at positions corresponding to the LED elements (5) of the substrate (7). Each LED light guide plate (9) has a substrate-side protrusion (27) which is a portion to-be-held. The substrate-side protrusion (27) has a sectional shape which becomes smaller toward the substrate (7). The substrate-side protrusions (27) are fitted into the holding holes (37, 39) of a keeper plate (11) which is a holding member. The shapes of the holding holes (37, 39) are different in accordance with the arrangements of the LED light guide plates (9) in a light guide direction. Thus, in spite of the same shape of the LED light guide plates (9), the mounting heights thereof can be made different depending upon places. It is accordingly possible to provide a light emitting apparatus which can decrease the sorts of components.

  • Patent number: 6865342
    Abstract: Herein disclosed is an operation lever apparatus which comprises a retaining member having a reference axis, a first operation lever having a reference axis and mounted on the retaining member, the first operation lever being movable with respect to the retaining member to assume two different operation positions including a first position in which the reference axis of the first operation lever is held in coaxial relationship with the reference axis of the retaining member, and a second position in which the reference axis of the first operation lever is tilted with respect to the reference axis of the retaining member, first detecting means for detecting a tilt direction of the reference axis of the first operation lever with respect to the reference axis of the retaining member, a second operation lever having a reference axis and mounted on the first operation lever, the second operation lever being movable with respect to the first operation lever to assume two different operation positions including a f
