Abstract

A key holding device with illuminating function includes a case having a pair of lengthwise guiding channels provided at two sides near a front end thereof for holding a U-ring thereto, so that a plurality of keys may be held on the U-ring. An illuminator lamp and a banknote test lamp are provided in the case at predetermined positions and could be turned on via depression of two push buttons on the case separately electrically connected to the two lamps. A slide switch is further provided on the case. When the slide switch is shifted to a side corresponding to the illuminator lamp, the illuminator lamp is kept turned on without the need of continuously depressing the push button corresponding to that lamp.

Claims

1. A key holding device with illuminating function, comprising a case that defines an inner space for accommodating a circuit board and a battery supplying power to said circuit board;

and said case being provided at predetermined positions with a first push button and an illuminator lamp that are electrically connected to circuits on said circuit board, and at a peripheral edge with at least a pair of lengthwise guiding channels for a U-ring to movably connect thereto for holding a plurality of keys;

whereby when said first push button is depressed and held to this position, said illuminator lamp is turned on to project bright light.

2. The key holding device with illuminating function as claimed in claim 1, wherein said case is further provided with a second push button and a banknote test lamp that are also electrically connected to circuits on said circuit board, whereby when said second push button is depressed and held to this position, said banknote test lamp is turned on to project ultraviolet rays.

3. The key holding device with illuminating function as claimed in claim 1, wherein said case is further provided with a slide switch electrically connected to circuits on said circuit board, whereby when said slide switch is shifted to one side corresponding to said first push button, said illuminator lamp is kept turned on.

4. The key holding device with illuminating function as claimed in claim 2, wherein said case is further provided with a slide switch electrically connected to circuits on said circuit board, whereby when said slide switch is shifted to one side corresponding to said first push button, said illuminator lamp is kept turned on.
