Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an aerial display device that displays desired information in the air by utilizing an afterimage effect.

[Conventional technology and its problems]

In conventional watches, the time is displayed using a display device that is equipped with all the time display patterns. For this reason, a large time display is required, and when the time is displayed using electrical means by emitting light, a large amount of electricity is consumed, and especially in watches with a large display, the clock device is also large and large. It was expensive and had high running costs.

In addition, none of the watches could be said to be of high interest.

Furthermore, when displaying desired information in a dot matrix, light-emitting elements for all the dots required to display a single digit are required, whereas a general display device that displays multiple digits requires Therefore, light-emitting elements with a number of dots as many as 300 digits were required.

Therefore, a huge number of light emitting elements are required.
If the dot matrix is coarse, it is not so bad, but in recent years, in order to display high quality, the number of dot matrices has been increased, for example, 24 × 24 or
In a case where the size is 48×48 or even larger, the number of light emitting parts required becomes particularly large.

In addition, as described in Japanese Patent Application Laid-Open No. 185076/1984, an idea was devised to draw an image in space by rotating a luminescent block.

However, in order to detect the position of the light emitter block, this device requires a separate rotating body to support the light emitter block, and moreover, it is necessary to maintain electrical contact with the outer periphery of this rotating body that rotates at high speed at all times. A power transmission mechanism for transmitting driving power to the light emitting block is inevitable. Therefore, the structure was complicated and the reliability was low.

Moreover, as is clear from Fig. 4, one electrical contact part of the power transmission mechanism on the outer periphery is connected to one light emitting element of the light emitter, which is extremely unusable, and the structure is shaped like a complicated dot matrix. It was difficult to display such information.

[Means for solving problems]

The present invention has been made with the aim of solving the problems of the prior art described above, and includes the following configuration as a means for solving the problems described above.

That is, a display means in which a predetermined number of light emitting parts are arranged in rows, a moving means for repeatedly moving the display means to the same range, and a predetermined position in the same range as the display means is moved by the moving means. A reference position detecting means for detecting arrival, and a display driving means for causing a light emitting part of a display means being moved by a moving means to emit light in chronological order and displaying the supplied display information in a dot matrix pattern using an afterimage effect. The display driving means determines the light emission switching time for each column in which the light emitting parts of the display means emit light in chronological order based on the detection time when the reference position detection means reaches the predetermined position, and the display driving means determines the light emission switching time for each column in which the light emitting parts of the display means emit light in chronological order, and generates a dot matrix pattern for each light emission switching time. The display pattern for each column is sequentially emitted from the light emitting section.

Among these, for example, the display means is formed by arranging a predetermined number of light emitting parts in a row near one end of the elongated part, and the moving means is made of a ferromagnetic material near the other end of the elongated part. a locking means formed with a locking means that swingably locks the elongated portion at an intermediate portion of the elongated portion; and the other end of the elongated portion with the locking portion of the locking means as a pivot center. Excitation means generates a magnetic force downward for a predetermined period of time to act on the ferromagnetic material of the elongated part to cause the elongated part to reciprocate in a pendulum shape, and the display drive means detects the reference position of the elongated part. Detection by means Performs a pendulum movement from a predetermined position, and emit light for each column in which the light emitting part of the display means emits light in chronological order by dividing the time required to change the direction by the number of display columns in the vertical direction of the display dot pattern. It is possible to perform time-division display by determining the switching time.

Furthermore, the display means includes a predetermined number of light-emitting parts arranged in a row near one end of the elongated part, and the moving means rotates the position of the light-emitting parts by rotating the elongated part. It may be something that makes you exercise.

[Effect]

In the above configuration, the desired information is displayed in the air using the afterimage effect, which is an extremely hobbyist method, and the display device has a simple configuration, and large displays can be easily performed at low cost, and the aerial display has low running costs. Provide equipment.

〔Example〕

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings.

[Description of the structure (Figs. 1 and 2)] Fig. 1 is a perspective view of an embodiment in which the present invention is applied to an aerial display timepiece. Explain.

In the figure, 1 is the main body, 2 is a display section (display means) arranged near one end of the arm 7, and in this embodiment, eight light emitting elements (light emitting sections) 2a to 2g are arranged. There is. However, the number of light emitting elements is not limited to the above example, and may be 12, 24, or more.

In the case of this embodiment, even if the number of dot matrices is increased, it is only necessary to increase the number of light emitting elements for one row. Therefore, when high-quality display is desired, significant effects can be achieved by applying this embodiment.

3 is a permanent magnet fixed to the other end of the arm 7; 4 is a reference position sensor that detects the reference position of the permanent magnet 3 disposed in the main body 1; 5 is an excitation coil built into the main body 1; 6 is an excitation sensor that detects the excitation timing of the excitation coil 5 built in the main body 1, and 7 is provided with the display section 2,
The arm to which the permanent magnet 3 is fixed, 8 is the main body 1
This is a holding part that swingably holds the arm 7 installed upright.

Further, reference numeral 10 shows an example of a time display that is displayed as an afterimage by the swinging of the display unit 2.

FIG. 2 shows a block diagram of the electrical circuit section, etc. of this embodiment.

In the figure, the same components as in FIG. 1 are given the same numbers.

In FIG. 2, reference numeral 20 denotes a timekeeping section that measures time, and uses a commonly available clock IC. 21 is a decoder which receives the time display character code from the clock section 20, converts it into a dot pattern corresponding to the character code, and sends it to the display drive section 2.
Output to 2. Reference numeral 22 denotes a display driving section, which displays the dot pattern sent from the decoder 21 on the display section 2 for each dot pattern row. In this embodiment, the dot pattern is time-divided for each vertical row. and display it.

A control section 23 controls the decoder 21 and the display driving section 22 in synchronization with the clock signal from the oscillator 24 and the detection of the reference position by the reference position sensor 4. The control unit 23 also drives the pendulum driver 25 for a certain period of time in synchronization with the excitation sensor 6 reaching the excitation position of the permanent magnet 3 to excite the excitation coil 5 and cause the arm 7 to make a pendulum movement. As a result, the display unit 2 also moves in a pendulum manner, and by sequentially displaying the dot pattern for displaying the time from the reference position in a time-division manner, it is recognized as if the dot pattern representing the time was drawn in the air due to the afterimage effect of the eye. can.

It goes without saying that the lower part of the arm 7 may be made of a ferromagnetic material instead of a permanent magnet, and the sensor section may be a sensing mechanism made of the ferromagnetic material.

[Description of operation (FIGS. 3 and 4)] Hereinafter, details of the time display control of this embodiment having the above configuration will be explained with reference to the flowchart of FIG. 3.

In step S1, it is checked whether the permanent magnet 3 fixed to the arm 7 has reached the upper surface of the excitation sensor 6 built into the main body 1. Permanent magnet 3 is excitation sensor 6
When the top surface is reached, the process proceeds to step S3, where the control section 2
3 drives the pendulum driver 25 for a certain period of time to excite the excitation coil 5. As a result, the arm 7 to which the permanent magnet 3 is fixed makes a permanent pendulum movement about the arm holding position of the holding part 8.

The above explanation is for the case where the excitation sensor 6 is arranged near one reciprocating point of the pendulum movement, and the excitation coil 5 is arranged near the lowest point of the pendulum movement and the excitation coil 5 is arranged near the lowest point of the pendulum movement. When the excitation sensor 6 is disposed at the excitation coil 5, the excitation coil 5 may be driven at a predetermined timing when the arm 7 moves in the direction of the excitation coil 5 from the reciprocating point.

If it is determined in step S1 that the excitation sensor is not at the position, the process proceeds to step S5, where it is checked whether there is a detection output from the reference position sensor 4 or not. If there is no detection output from the reference position sensor, the process returns to step S1.

If there is a detection output from the reference position sensor, the process proceeds to step S7, where the decoder 21 selects the first time display digit of the clocked time output as a character code from the clock section 20, and converts this character to step S9. Convert the code to the corresponding display dot pattern.

The display driving section 22 captures and holds this display dot pattern in step S11, and displays the first row of the display dot pattern on the display 2 in the subsequent step S13.

Then, in step S15, the user waits for a predetermined time to elapse, and when the predetermined time has elapsed, the process proceeds to step S17, where the display on the display section 2 is changed from the first row to the next row, and the next row of dots is displayed. Show patterns.

Then, in step S19, the program waits for a predetermined time to elapse in the same way as in step S15, and when the predetermined time has elapsed, the process proceeds from step S19 to step S21, where it is checked whether or not the display of the display dot pattern for one digit has been completed. If the display of the digits has not been completed, the process returns to step S17 and the next column is displayed.

If the display of one digit has been completed, it is checked in step S23 whether or not the display of all digits of the time display from the clock section 20 has been completed, and if not all the digits have been displayed, the process is proceeded to step S25. The decoder 21 selects the next time display digit from the timer section 20, and proceeds to step S.
Returning to step 9, a dot pattern corresponding to the character code of this digit is generated and displayed.

If all digits have been displayed in step S23, the process returns to step S1.

As mentioned above, the time output pattern is sequentially emitted on the display unit 2 in chronological order along the vertical axis, and by shaking it, the afterimage effect of the eye causes the output pattern to emit light as shown in Figure 1 10 or as shown in Figure 4. A pattern emerges.

In FIG. 4, 2a to 2g are light emitting elements arranged in the display section 2, and the light emitting elements 2a to 2g are
Use to display the display pattern for each column of the dot matrix display. The display timing for each column may be time-divisionally driven by dividing the time required for the arm 7 to make a pendulum movement from the reference position and change the direction by the number of display columns in the vertical direction of the display dot pattern.

In the example in Figure 4, the displayed time is "8:13",
A case is shown in which the number of vertical display columns of the display dot pattern is 17.

Therefore, in the example of FIG. 4, steps S15 and S
The predetermined time mentioned in 19 is the time required for the arm 7 to make a pendulum movement from the reference position and change the direction divided by 17, which is the number of vertical display columns of the display dot pattern, and this time is This is the display pattern change time for each column.

In the example shown in FIG. 4, all of the light emitting elements 2a to 2g emit light in the first column of the time display, the light emitting elements 2a, 2d, and 2g emit light in the second and third columns, and the fourth column Control is performed so that all of the light emitting elements 2a to 2g emit light again, and in the subsequent fifth row, all of the light emitting elements do not emit light. Hereinafter, in the second digit, the sixth and eighth columns do not emit light at all, and in the seventh column, the light emitting elements 2b, 2c, 2e, and 2f emit light.
Thereafter, the third and fourth digits are similarly time-divisionally displayed as shown in FIG.

As is clear from FIG. 1, the time from when the arm 7 reaches the reference position and the detection output from the reference position sensor 4 is output until the next detection output from the reference position sensor 4 is generated is due to the pendulum movement. This is the time it takes to change the direction at the excitation sensor 6 arrangement position, reach the reference position sensor 4 position again, and change the direction here. Therefore, the time required for the arm 7 to make a pendulum movement from the reference position and change its direction can be determined as 1/2 of the detection output interval of the reference position sensor 4.

[Other Examples]

In the above explanation, the light emitting elements of display section 2 are 2a to 2g.
Although seven light emitting elements are shown as an example, by increasing the number of light emitting elements, a clearer and higher quality display pattern can be produced.

Further, in this embodiment, since the display section only has a capacity equivalent to one row of dot patterns, display can be performed in a large display space with a simple configuration and control. Furthermore, running costs in this case can also be kept extremely low.

Furthermore, it goes without saying that the display section 2 may not only be moved in a pendulum-like manner, but may also be moved in parallel, for example, in the direction of the horizontal axis (1 to 17) in FIG. As a result, a display as shown in FIG. 4 is obtained.

Alternatively, the arm 7 may be rotated around the locking position with the holding part 8, and the display unit 2 may be controlled to be rotated around the locking point with the holding part 8. This also provides a display result as shown in FIG. 1. In this case, since the displayable area expands in a ring shape, it is possible to display not only the time but also a large amount of information, including various advertisements and messages.

Further, in the case of FIG. 4, the display section 2 is moved in parallel, but it goes without saying that it may be moved in rotation. In this case, if the display section 2 is always directed toward the outer circumferential surface of the rotary motion, the display as shown in FIG. 4 can be obtained from any position on the outer circumference. In this case as well, the display capacity becomes very large, and it is possible to display not only the time but also a large amount of information, including various advertisements and messages.

[Effect of idea]

As explained above, according to the present invention, it is possible to provide an air display timepiece that can display the time in the air and is highly entertaining and has a simple display section configuration.

In addition, a large time display space can be easily realized at low cost and with low running costs.
