<p>PROBLEM TO BE SOLVED: To provide the subject displaying device capable of holding the minimal functions to operate at least an arithmetic means and a displaying part even if an electrical operating part changed into an inoperative state by respectively forming a power source for the arithmetic means and the displaying part and a power source for the electrically operating part into separate ones. SOLUTION: This length measuring and displaying device 1 is provided in a reel for fishing, comprises an arithmetic means 2 for electrically performing computing processing of the length measurement of a fishing line, a displaying part 3 for electrically displaying the results of computing of the arithmetic means 2 and an electrically operating part 5 other than the arithmetic means and the displaying part 3 and further contains power sources therefor therein. At least the power source 4 for the arithmetic means 2 and the displaying part 3 and the power source 7 for the electrically operating part 5 are respectively formed into separate ones. A solar cell can be used as the power source 4 for the arithmetic means 2 and the displaying part 3.</p> |
