BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to a rotating display element which is provided with a display surface member having a plurality of display surfaces and is arranged to select one of the display surfaces by rotating the display surface member and, further, the invention pertains to a display unit using such a rotating display elements.
BACKGROUND ART
Heretofore, various rotating display elements have been proposed, which are, however, defective in that the rotating mechanism for driving the display surface member must be provided separately of the rotating display element, or in that a selected one of the display surfaces of the display surface member does not assume a correct position.
Furthermore, a variety of display units using the rotating display element have also been proposed in the past but, in addition to the abovesaid defects of the rotating display element, the conventional display units possess the drawback of involving the use of complex means for selecting the plurality of display surfaces of the display surface member of the rotating display element.
DISCLOSURE OF THE INVENTION
The present invention is to provide a novel rotating display element free from the abovesaid defects and a display unit using such display element.
According to the display element of the present invention, only by supplying a power source to a first exciting winding of a stator of a motor mechanism through first or second power supply means and by supplying a power source to a second exciting winding of the stator of the motor mechanism through a third or fourth power supply means, a selected one of the plurality of display surfaces of the display surface member can be caused to face forwardly. Therefore, it is possible, with a simple arrangement, to selectively direct the plurality of display surfaces of the display surface member to the front.
Further, according to the display element of the present invention, even if the power supply to the abovesaid first and second exciting windings are cut off after the plurality of display surfaces of the display surface member are selectively directed to the front, since first and second double-pole permanent magnet members of a rotor forming the abovesaid motor mechanism act on first and second magnetic members of the stator forming the motor mechanism, the display surface member can be held with a selected one of the plurality of display surfaces thereof facing to the front. Consequently, no unnecesary power consumption is incurred.
Moreover, according to the display element of the present invention, the above-mentioned motor mechanism is incorporated in the display surface member. Accordingly, there is no need of preparing a display surface member driving mechanism separately of the display element.
In addition, according to the display unit of the present invention, the abovesaid display element of the present invention is employed, and the device for driving the display element is required only to have first and second power supply means for supplying power to the first and second exciting windings of the display element and third and fourth power supply means for supplying power to the second exciting winding. Accordingly, the display element can be driven with a simple arrangement.
