Abstract

PURPOSE:To obtain an electronic hourglass accurate and easily visible with the electronic application of a mechanical hourglass by controlling the lighting and extinguishment of a plurality of display elements the same in the area on symmetrical upper and lower side display surfaces through a counter for respective display surfaces. CONSTITUTION:Counters are controlled separately corresponding to symmetrical upper and lower side display surfaces 3 and 4 for a constricted part 2 through a switch responding to the state of the body, uprighted or inverted. When the body 1 of an hourglass is uprighted or the like, counters corresponding to the surfaces 3 and 4 are set at the max. value and 0 in the initial state and then, up or down count clock pulses separately. Display elements 5 such as crystal liquid the same in the area as the surface 3 all lighted goes out sequentially one at a time while element 5 on the surface 4 light sequentially one at a time. When the body 1 is inverted, the same action takes place. Thus, the functions of a mechanical hourglass go electronic completely to obtain an accurate and easily visible electronic hourglass.

As is clear from the above description, the present invention is directed to a large number of displays arranged on the upper and lower display surfaces, each having a constant area. The elements are lighted one by one from the bottom (as the elements are arranged in rows, the existing mechanical hourglass can be completely electronicized, the timekeeping operation can be made accurate, and the display can be moved). Since the display area is constant, it is easy to see the passage of time visually. Since the degree of freedom is the same as above, the mechanical strength can also be made strong.
