The gate pulse P2 output from the second oscillation circuit 40b is input to the inverter 41 as a gate input together with the drive pulse P1. Only the drive pulse P1 when the gate pulse P2 is Low turns on the drive circuits 42a and 42b and the LED 10
a and 10b blink.

In FIG. 7, point S1 is a drive pulse P1 generated by the first oscillation circuit 40a (see FIG. 8A), and point S2 is a gate pulse P2 generated by the second oscillation circuit 40b (see FIG. 8).

Set the pulse width to 0.5 ms at 0 ms, and set the gate pulse P
2 is set to a period of 1 s and a pulse width of 0.5 s. Since the period of 60 ms corresponds to a rotation speed of the rotating body of 1000 rpm, when the rotating body is rotating at a multiple of 1000 rpm, the LED 10 blinks at the same rotational position of the rotating body, and the visual display of the display body is performed. The information will appear to stop.

According to the above-described rotary display device, when the rotating body is rotated so as to rewind the string member wound around the pulley, the rotating body rotates at a high speed. When rotated at high speed, the connection between the pulley and the rotating body by the connecting means is released, and the rotating body rotates freely with respect to the pulley until the rotation speed decreases. When the rotating body rotates at a high speed, the rotation detecting means 6 operates, and the lighting control means 11 and the LED 10

Light emitted to the end faces of the display panels 7 and 8 by the LEDs 10a and 10b is refracted by the refraction unit 35, and can be visually recognized as visual information a and b from outside the housing 1 through the filter panel 36.

The LEDs 10a and 10b blink alternately (500 ms) at a constant cycle (60 ms) during rotation of the rotating body, so that the rotating speed of the rotating body A is 1000 rpm or 100 rpm.
At a multiple of 0 rpm, when the lighting control means 11 synchronizes with the cycle (60 ms) at which the LED 10 blinks, the LED 10 blinks at the same rotational position of the rotating body, and the visual information displayed on the display body stops. I can see Moreover, 2
Since two LEDs alternately illuminate the two display boards, different visual information formed on the display boards will be displayed alternately, expressing an action as if the dog were opening and closing a mouth. You can enjoy the visual pleasure that can not be obtained with a yo-yo toy that simply blinks while rotating.

FIGS. 9 and 10 show another example of a rotary display device which comprises two octagonal rings 50,
A frame 52 formed by superimposing 51 and a rotating body B fixed to a core shaft 55 rotatably supported by bearings 53 and 54 attached to the upper and lower sides of the frame, The whole is formed to imitate a gyrocoma.

A gear 56 is attached to a lower portion of the core shaft 55, is housed in a gear box 57 formed at a lower portion of the frame 52, and has an opening 58 formed on a side surface of the gear box 57 to hold the operating rod 60. The core shaft 55 can be rotated at a high speed by inserting the rack gear portion 61 and strongly pulling out the operating rod 60.

The rotating body B fixed to the core shaft 55 includes an upper member 6
2 and a lower member 63, inside which display panels 7, 8
And a filter panel 36 that is superimposed on the display plate 8,
The display panels 7, 8 and the filter panel 36 are sandwiched from above and below, and the LED 10a

According to the rotation display device having the above configuration, first, the rack gear portion 61 of the operating rod 60 is inserted through the opening 58 formed on the side surface of the gear box 57, and then the operating rod 60 is moved to the gear box 57.
Pull hard until it comes out of. By pulling the operating rod 60, the core shaft 55 is vigorously rotated via the gear 56. When the core shaft 55 rotates, the rotating body B rotates at a high speed. When the rotation is detected by the rotation detecting means 6, a voltage can be supplied to the lighting control means 11 and the LED 10, and the oscillation circuit 40 drives the driving pulse. Since P1 and the gate pulse P2 are generated, the LEDs 10a and 10b blink alternately and illuminate the end faces of the display plates 7 and 8 alternately. LED1
The light of 0 is refracted by the refraction section 35 and the filter panel 3
6 through the round opening 64 formed in the upper member 62.

When the rotating body B rotates at a high speed and the rotating speed of the rotating body B becomes a multiple of 1000 rpm, the visual information appears to stop, and when the rotating speed starts to decrease, the visual information is disturbed, and when the rotating speed decreases by 1000 rpm from the previous time. Also, the visual information appears to be stopped, and the visual information can be stopped and viewed several times before the rotating body B reaches 1000 rpm.

In the present invention, two pieces of visual information can be alternately displayed by using two display boards. However, only one piece of visual information may be displayed on one display board. At this time, the lighting control means does not need the oscillation circuit 40b that generates a gate pulse for alternately selecting the LEDs corresponding to the two display boards, and the oscillation circuit that generates a driving pulse for blinking the LEDs is not necessary. Only the circuit 40a is required.

[0033]

According to the first aspect of the present invention, the luminous body blinks at a constant period during the rotation of the rotator, so that when the rotation speed of the rotator reaches a predetermined rotation speed, the disturbed visual information stops. Thus, it is possible to realize a rotary display device which can be seen and can be reduced in size with a simple structure.

According to the second aspect of the present invention, since the light of the illuminator that irradiates the display panel is not applied to the area other than the end face of the display panel, information other than the visual information to be displayed is applied and visually recognized together with the visual information. Since there is no such thing, only visual information can be seen in a clear state.

According to the third aspect of the present invention, by inserting the tip of the luminous body into the notch formed in the display panel,
The light of the illuminant can be irradiated to the display panel without waste, and the visual information can be made clearer.

According to the fourth aspect of the present invention, different visual information is displayed in order by superimposing the display boards on which different visual information is formed and blinking the light emitting elements for each display board, so that it looks like a moving picture. Therefore, it is possible to provide complicated visual information with a simple structure.

According to the fifth aspect of the present invention, different visual information formed on the display panel is alternately displayed, and for example, a moving image such as a dog opening and closing a mouth can be displayed. You can express and enjoy the visual pleasure that cannot be obtained with a yo-yo toy that simply blinks while rotating.

According to the sixth aspect of the present invention, visual information is clearly visible when the number of revolutions of the rotating body reaches a certain number of revolutions, so that it is possible to enjoy a frame play that cannot be enjoyed with a conventional rotating toy. it can.
