[0002]

2. Description of the Related Art Conventionally, a light-emitting part such as a candle is attached to the tip of a rod-shaped body like a penlight in a display device using this kind of simple light, and afterimages are produced by shaking it left and right in a dark place. There was something to get. Also, 2
For a two-dimensional display, I used to write a two-dimensional image on a small flag and shake it.

[0003]

The penlight cannot display or is extremely difficult to display two-dimensionally, such as characters and figures, and the small flag cannot be used in a dark place, and the display content can be changed. I had to prepare several sheets.

It is an object of the present invention to easily obtain a two-dimensional afterimage of various changes by arranging a large number of light emitting elements in a rod-shaped case in a substantially straight line and swinging the light emitting elements to the left and right.

[0005]

The present invention is directed to a rod-shaped case 1.
0, a plurality of display elements 11 arranged substantially linearly in the rod-shaped case 10 at predetermined intervals, a drive control means 12 for controlling the blinking drive of the plurality of display elements 11, and a drive control means. A display device for a two-dimensional afterimage, comprising an image information memory 13 coupled to 12 and storing image information of a two-dimensional afterimage due to reciprocating movement and blinking of the display element 11.

[0006]

The grip 36 is gripped by hand, and the rod-shaped case 10 is repeatedly reciprocated several times in one second within a width of about 30 cm. Then, the display element 11 blinks in accordance with the reciprocating movement to form an afterimage. Since the afterimage of human being is about 0.1 seconds, the virtual display area 2

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described with reference to FIGS. In FIGS. 1 and 2, reference numeral 10 denotes a rod-shaped case, and the rod-shaped case 10 is formed by fitting an upper case 30 and a lower case 31 and is formed with concavities and convexities so as to form a grip 36 at a lower portion thereof, and hits the outer periphery. A soft member 32 made of rubber or the like is covered for safety when dropped or dropped. A plurality of display elements 11 such as LEDs are arranged substantially linearly on the front surface of the upper case 30, and a plurality of mode changeover switches 23 are provided near the grip 36.
Is provided.

The display elements 11 are arranged substantially linearly in a state of being in close contact with each other, and if possible, two or more rows,
In the embodiment, the ones which emit light of three primary colors of R (red), G (green), and B (blue) are arranged. The rod-shaped case 1
A printed circuit board 33 to which the display element 11, the mode changeover switch 23, an electronic component 34 and the like are attached is provided inside the 0, and a battery 35 is housed in the grip 36.

FIG. 3 shows an internal control circuit. In FIG. 3, the display element 11 shows a case in which 32 pieces are divided into four blocks 11a, 11b, 11c, and 11d of 8 pieces and arranged linearly. Of course, it is not limited to this number. These display elements 11 are connected to a drive control means 12 including a driver 17 and a selector 18 for each block 11a, 11b, 11c, 11d. Note that each block may be replaced by the driver 17 instead of the selector 18.

The drive control means 12 is connected to the CPU 14. Further, the CPU 14 includes an image information memory 13 that stores image information of an afterimage, a program ROM 21 that stores a control program, and a clock generation circuit 22 that generates a basic clock for setting the blinking cycle of the display element 11. , A mode switch 23 for switching the blinking cycle in multiple stages, scrolling the blinking of the display element 11 from top to bottom, scrolling from the middle to both ends, switching between a moving image and a still image, switching of the power supply, etc. Acceleration detecting means 24 for detecting a reversal signal of reciprocal turn-back when 10 is swung left and right.
Are connected.

The operation of the above configuration will be described.
The grip 36 is gripped with a hand and the rod-shaped case 10 is shaken left and right. At this time, the rod-shaped case 10 repeats reciprocating motion several times in one second in a range of, for example, a width of about 30 cm while keeping the parallel state as much as possible. Then, the display element 11 blinks in accordance with the reciprocating movement to form an afterimage. More specifically, the mode changeover switch 23 sets an appropriate cycle among a plurality of preset blinking clock cycles. For example, a person such as a child who swings to the left and right is not so fast, selects a slow cycle. In order for the afterimage to not disappear, a fast cycle is desirable, but it should be set in several stages in consideration of human ability. Next, with the mode changeover switch 23,
Whether the moving image data is read from the image information memory 13, the still image data is read, or what kind of data is used, the display element 11 in the first column and the display element 11 in the second column are set. The mode is selected such as different images, scrolling from top to bottom, from bottom to top, or from the middle to both ends. Selected clock generation circuit 2
Image data is sequentially read from the image information memory 13 to the CPU 14 based on the clock 2
14 to driver 17 of drive control means 12 and selector 1
A control signal is sent to 8 to make the plurality of display elements 11 sequentially blink according to the data. Then, since the afterimage of a human is about 0.1 seconds, a predetermined image such as a still image or a moving image appears in the virtual display area 25.

A specific example of the image thus formed will be described with reference to FIGS. In the following description, it is assumed that the display element 11 has two columns. FIG. 4A shows an image of the display element 11 in the first column. For example, it is assumed that all are turned on, all are turned off, scroll is performed from top to bottom, bottom to top, and halfway to both ends. FIG. 4B is an image of the display element 11 in the second column. For example, all lights up at the first clock, all lights off at the second and third clocks, third light at the third clock,
It is assumed that the H-shaped afterimage is formed by controlling the fourth display element 11 to be turned off and the others to be turned on. Then, the entire image is obtained by superimposing FIGS. 4A and 4B.

In FIG. 5A, it is assumed that the display element 11 in the first column forms a T-shaped afterimage of red, for example. Figure 5
(B) is a display element 11 in the second column, for example, in green X
It is assumed that the afterimage of the character is formed. Then, the entire image is obtained by superimposing FIG. 5A and FIG. 5B, but since these characters are difficult to recognize, it is possible to use a character-matching quiz game.

FIG. 6 shows that when the rod-shaped case 10 is reciprocated within a range of, for example, a width of about 30 cm while keeping the parallel state,
In the case where a predetermined virtual display area 25 as shown in (a) is designed to be formed, as in (b), an example in which images are accurately overlapped in a reciprocating manner even when folded back in the middle It is shown. For example, in the case where the virtual display area 25 is formed when eight display elements 11 arranged vertically are shaken left and right for 10 clocks, as shown in FIG. When folded back, the acceleration detection means 24 outputs an inverted signal. When this inverted signal is input to the CPU 14, C
The PU 14 outputs the data from the image information memory 13 in the reverse direction from the 7th clock. That is, an afterimage such as (d) is formed from the first clock to the seventh clock, and when the image is inverted at the seventh clock, this time, as shown in (e) from the seventh clock to the first clock. Afterimages are formed, these overlap,
The afterimage is as shown in (c).

If, as shown in (b), the return signal is output at the seventh clock and the inverted signal is output from the acceleration detecting means 24, if the reverse signal is not output from the seventh clock, the forward and backward movements are performed. The images do not match, and an accurate afterimage cannot be obtained. That is, an afterimage such as (g) is formed from the 1st clock to the 7th clock, and is inverted at the 7th clock, and an afterimage such as (h) is generated from the 10th clock to the 4th clock. If images are formed, they overlap each other and the target image cannot be obtained as in (f). The present invention solves these problems.

In the description of FIGS. 4 to 6, the display element 11 is used.
Although there are two columns, there are three columns as shown in FIG. 1, and the first column, the second column, and the third column are R (red) and G, respectively.
In the case of arranging so as to emit light of three primary colors of (green) and B (blue), these timings are controlled by controlling the blinking timing of the first row, the second row, and the third row. Combination colors, ie M (magenta), S (cyan), Y
(Yellow) and W (white) can be obtained, and a larger number of colors can be obtained by controlling the brightness.

A second embodiment of the present invention will be described with reference to FIGS. In the first embodiment, when the rod-shaped case 10 is swung to the left and right, the rod-shaped case 10 is swung in a substantially parallel state. In this case, the absolute position is detected by the absolute position detecting means 15 from the moving speed of the rod-shaped case 10, the control signal is calculated by the CPU 14 and read from the image information memory 13. That is, the photo interrupter 20 is rotatably attached to the lower portion of the rod-shaped case 10 near the grip 36. In this photo interrupter 20, two rows of pores are formed in a circle at a predetermined angle, and even if the main body is swung to the left or right, it is always held at a constant angle by a weight or the like. Then, when the rod-shaped case 10 is swung to the left or right with the vicinity of the photo interrupter 20 as a fulcrum, the rotation direction and speed of the rod-shaped case 10 are detected.

The signal detected by the photo interrupter 20 is sent to the position / direction control circuit 19, converted into a control signal showing the absolute position of the rod-shaped case 10 and a control signal showing the rotation direction, and sent to the CPU 14. .. Then,
Based on these control signals, the CPU 14 calculates the absolute position of the rod-shaped case 10 which is swung to the left and right, and the image data is read from the image information memory 13 using this as an address, and the fan-shaped case shown in FIG. A predetermined afterimage is formed in the virtual display area 25 of. For example, when 32 display elements 11 are vertically arranged, the virtual display area 25 has 48 display elements 11 in the horizontal direction.
Shall be formed by the afterimage of. In addition, the rod-shaped case 10
When four round trips are made within one second within the virtual display area 25, the round trip time is 250 milliseconds, so the horizontal clock interval is 2.6 milliseconds. Virtual display area 25
If the afterimage formed in (1) is a moving image, a signal is output from the frame counter 16 every one or more frames to control the data from the image information memory 13.
