The driving device 4 has a conversion means (not shown) such as a crank for changing the rotational motion into a reciprocating motion. One end of the driving rod is connected to the display unit 2, and the other end of the driving rod 3 is connected to this conversion means. Due to the reciprocating motion of the driving device 4, the display unit 2 is perpendicular to the light emitting surface of the light emitting element 1 (the upper surface of the display unit 2 in the figure) (vertical direction in the figure).

A tomographic image of each part of the three-dimensional shape required to display the three-dimensional shape is created and stored. Then, the display unit 2 is vibrated (reciprocated) in a direction perpendicular to the light emitting surface of the light emitting element 1 (the upper surface of the display unit 2 in the figure) via the driving rod 3 by the reciprocating motion of the driving device 4. Move). In order to obtain a sufficient afterimage effect, the vibration (reciprocation) of the display unit 2 at this time is, for example, when the display unit 2 has a size of 5 to 15 cm × 5 to 15 cm, the frequency of the display unit 2 is 1 minute. 600 ~
Approximately 2,000 times, the vertical displacement (amplitude) is 5

The information of the two-dimensional tomographic images is transferred alternately from the memories 42a and 42b. Moreover, the selectors 41 and 43 cooperate, for example, while transferring and storing the information of the two-dimensional tomographic image from the selector 41 to the memory 42a, the selector 43 transfers and stores the information of the two-dimensional tomographic image from the memory 42b.
While reading and conversely transferring and storing the information of the two-dimensional tomographic image from the selector 41 to the memory 42b, the selector 43 is controlled to transfer and read the information of the two-dimensional tomographic image from the memory 42a. You.

By such control, the two buffer memories 42a and 42b continue to operate without any break. That is,
Two buffer memories 42 are provided by selectors 41 and 43.
a and 42b are controlled alternately.

On the other hand, when the position of the display section 2 is detected by the position detecting device 5, the address generator 46 responds to this information to determine the address of the two-dimensional tomographic image of either of the two buffer memories 42a and 42b. An address signal for controlling whether to transfer to the latch 44 and an address signal for controlling the clock generator 45 for generating a signal for controlling the display timing of the display unit 2 of the information of the two-dimensional tomographic image transferred from the latch 44 to the display unit 2 And generate.

The clock generator 45 also controls the display time in accordance with the display unit 2 in addition to the display timing on the display unit 2. The display unit 2 includes a part that moves linearly at a constant speed and a part that moves in an accelerating and decelerating manner, and the display unit 2 displays a display element or the like on the display unit 2. This is because it is necessary to control the light emission time in each of the constant velocity, acceleration, and deceleration portions to an appropriate value.

If the image information is sent to the display unit 2 in both directions, a clearer image can be obtained.

FIG. 14 shows a stereoscopic video apparatus according to a seventh embodiment of the present invention. In addition to the configuration of the stereoscopic video apparatus according to the sixth embodiment, a reset position detecting sensor 122 is added. This reset position detection sensor 103, 1
22 indicates, for example, the display unit 2 in the reciprocating vibration of the display unit 2.
, The reset pin 104 is detected at the turnback position at the maximum amplitude position. Further, as shown in FIG.
According to the stereoscopic video apparatus of FIG. 14, the image information is displayed on the display unit 2 in both directions of the return (outbound and return) directions when the display unit 2 reciprocates. As a result, the sixth
Even when the same driving frequency as the driving frequency of the display unit 2 used in the stereoscopic video device of the embodiment is used, the stereoscopic image is displayed using the apparently twice the driving frequency,
Further, a clear three-dimensional stereoscopic image can be displayed.

FIG. 16 is a flowchart showing the operation of the stereoscopic apparatus according to the seventh embodiment shown in FIG. In the figure, step S1501 is a step of determining whether or not the reset position detection sensor 103 has detected a predetermined reset position. As the reset position, for example, the position of a reset pin 104 provided adjacent to the position display unit 101 is set. Further, the position detection sensors 103 and 122 are set at both ends of the position of the reset pin 104 at the maximum amplitude.

In step S1502, step S15
When the reset position is detected at 01, the variable I is set to 0. Thus, the first image information is displayed on the display unit 2 in step S1504.

In step S1503, the next bar code or slit n is detected by the position detection sensor 102, and only when the detection signal exceeds a preset threshold as shown in FIG. 12, the next step S1504 is performed.
Proceed to.

At step S1504, the display unit 2 displays image information corresponding to the detected barcode or slit n. The above is the case of the going (outgoing) direction at the time of the vibration amplitude of the display unit 2.

Next, image display on the display unit 2 in the return (return) direction when the vibration amplitude of the display unit 2 is described will be described.

Step S1505 is a step for judging whether or not the reset position detecting sensor 122 has detected the reset position.
