Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an advertising display device using a magnetic reversal element that can drive a display body provided on a pendulum body by energizing an electromagnet.

(Prior art) Traditionally, to display gasoline prices at gas stations, numbers were displayed with paint on a glass plate.
It is simply a display that is illuminated by a light bulb.

In addition, as a generally known display body, Utility Model Application Publication No. 59-
There are Publication No. 128688 and Japanese Unexamined Patent Publication No. 1986-96986.

(Problem that the invention attempts to solve) According to the price display at a gas station,
During the day, the numbers are difficult to read due to the reflection of the sun, making them unsuitable for advertising purposes.

Furthermore, it is quite difficult to change the display device in response to fluctuations in gasoline unit prices.

According to a well-known document, Utility Model Application Publication No. 59-128688, numbers are displayed by arranging segment boards of the same shape on a display board, and to change the display, the display board must be attached one by one. It has to be changed and is complicated.

Furthermore, the device disclosed in JP-A-55-96986 has a light-emitting display using a fluorescent display tube, a light-emitting diode, or a liquid crystal arranged in parallel so that time and temperature can be displayed. They are complex, and if they are located outdoors like a gas station, the numbers are difficult to read in the daytime due to the reflection of the sun, making them insufficient for advertising purposes.

(Means for solving the problem) Therefore, the technical problem of this proposal is to create a display that can be easily changed, is easy to read during daytime, and has a great advertising effect. Another object of the present invention is to provide a display device that can display both the time and the price of gasoline, etc., using a display body formed using display segments made of magnetic reversal elements at a gas station. The technical means of the present invention to solve this technical problem is to arrange a plurality of display segments made of magnetic reversal elements in a rectangular line, and to arrange them linearly across the center of the rectangular line frame to form one display segment. In a display device configured to display characters or numbers by forming a unit display body and arranging these display bodies in a plurality of horizontal rows, the display device has a ¥ symbol segment at the topmost digit, and a ¥ symbol segment adjacent to the ¥ symbol segment. At the same time, a dot-like segment is arranged between the left and right two-digit unit display, and in the time display, a dot-like segment is formed by combining linear segments adjacent to the ¥ symbol segment. It consists of a segment of and a segment of a unit indicator,
An advertisement characterized in that the price display is composed of a ¥ symbol segment and a unit indicator segment, and the price display is composed of a ¥ symbol segment and a unit indicator segment, and is used for both time and price display. It is a display device.

(Example) The embodiments shown in the drawings will be described below.

First, to explain the magnetic reversal element used in the display body of the present invention, FIGS. 3 and 4 are examples thereof. In other words, in the state shown in FIG.
The plate-shaped body 4 of the fixed iron core 3 due to its own magnetic force
The display element 1' appears on the display surface A.

In this case, the magnet 2 of the pendulum body 1 is in direct contact with the plate-shaped body 4 of the stationary iron core and is strongly attracted to it, so that the display state of the display element 1' is reliably maintained.

Next, when the coil 6 of the electromagnet 5 is energized, the tip of the plate-like body 4 becomes the north pole, and the tip of the other plate-like body 7 becomes the south pole, so the magnet 2 is moved by the north pole of the plate-like body 4. The pendulum body 1 vibrates around the axis 9 of the frame body 8 as it is repulsed and attracted by the S pole of the other plate-like body 7, and the display element 1' is moved to the display surface A as shown by the imaginary line.
When the pendulum magnet 2 is attracted to the tip of the plate-shaped body 7, the non-display state of the display element 1' is maintained. In this case as well, the magnet 2 directly contacts and is strongly attracted to the plate-shaped body 7 by its own magnetic force, so that the non-display state will be reliably maintained even if the energization is subsequently stopped.

Next, when a current is applied in the opposite direction to the electromagnet 5 from the non-display state, an N pole is generated at the tip of the plate-like body 7, an S-pole is generated at the tip of the plate-like body 4, and the pendulum body 1
oscillates, resulting in the display state of the display element described above.

By reversing the direction of energization to the electromagnet as described above, the pendulum body can be swung and the display element can be reversed, and its position can be strongly maintained.

5 to 17 show examples of other magnetic reversal elements, and 10 is a mounting member to the display panel,
An electromagnet 11 is attached to this. The electromagnet 11 has an iron core 14 fitted into a bobbin 12 on which a coil 13 is wound as usual, and the attachment state of this iron core can be adjusted with a nut 15. The mounting member 10 has a support member 16 as a non-magnetic material made of a character frame, and the support member 16 and the iron core 14 are connected to each other.
There is a spacer 18 that fits around the iron core between the yoke 17 and the integral cross-sectional shape yoke 17.

This spacer 18 can be installed by selecting one of different lengths, and this fixation is done with a nut 15.
By abutting the tip of the support member 16 against the support member 16, it can function as a rotation stopper.

A permanent magnet fixing member 19 is swingably mounted on the support member 16 via a shaft 21 , a permanent magnet 20 is fitted into the permanent magnet fixing member 19 , and the protruding piece 19
a and 19b, forming a pendulum body 29.

A pin 22 is provided in a protruding manner on the permanent magnet fixing member 19, and the pin 22 is engaged with a guide hole 23 of the support member 16 to be slidable.

The display body 25 is attached to the bar 30 and
is integrally molded with the plate 24, and the boss 28 of the arm 27 is integrally molded on the plate 24.
A weight 26 is attached to the ring 27a of the arm 27.
is installed.

The boss 28 has a key groove 31 into which the key 3 of the pipe 33 protruding from the permanent magnet fixing member 19 is inserted.
2 will fit.

When the key 32 fits into the keyway 31, the pipe 33 fits into the shaft hole 34 of the boss 28.

From the above structure, the permanent magnet fixing member 19
and display body 25 can be separated from each other.

Now, if the electromagnet 11 is energized and a N pole is generated in the yoke 17 as shown in FIG. 16, the N pole of the permanent magnet will be repelled and the pendulum will rotate in the direction of the arrow, and the S pole of the pendulum will be the S pole of the yoke. The display body 25 is attracted to the N pole.
is moved from the display position to the storage position and is held as shown by the imaginary line in FIG.

When a current in the opposite direction is passed through the electromagnet 11, the yoke 1
7 changes from the north pole to the south pole, and the south pole of the pendulum body 29 is repelled by this and reversed, and the display body 25 returns to the display position.

As the pendulum body 29 moves laterally, the weight 26
The pin 22 of the permanent magnet fixing member 19 slides along the guide hole 23 to restrict the left and right movement of the pendulum. Left and right movement is restricted at both ends of the hole 23.

Therefore, by arranging and operating a plurality of display elements as described above, desired arithmetic numerals, alphabetic characters, and other advertising characters can be formed.

It goes without saying that the display body 25 and the pendulum body must be connected at an angle of 45° in order to carry out the above-described operation.

By the way, when it is desired to strengthen the coercive force of the pendulum body, it is necessary that the distance L between the yoke 17 and the pendulum body 29 shown in FIG. When the distance L is wide, the coercive force becomes weak.

Therefore, in order to adjust the coercive force according to the size of the display body 25, the yoke 17 and the support member 1 are required.
Prepare spacers 18 of different heights to be inserted between the yoke 17 and the pendulum body 29, and replace them to adjust the position of the yoke 17.
This is to adjust the

In the illustrated example, the pipe 33 of the permanent magnet fixing member 19 is fitted into the shaft hole 34 of the boss 28 where the weight 26 is located, and the key 32 is fitted into the key groove 31. Display body 25 integrated with boss 28
rotates together with the permanent magnet fixing member 19, that is, the pendulum body 29, but by removing the pipe 33 of the permanent magnet fixing member 19 from the shaft hole 34 of the boss 28, the display body and the pendulum body can be separated. .

Therefore, only the display body can be replaced while the pendulum body and the electromagnet that drives it remain the same.

The present invention uses magnetic reversal elements as described above, which are arranged as shown in Figures 1 and 2, and are reversed to display the price and time of gasoline, diesel oil, etc. at a gas station.

First, a plurality of display segments 35 made of magnetic reversal elements are arranged in a rectangular line shape. 3
5a shows the display segments arranged in a rectangular line.

35b is a display segment that linearly crosses the center of the rectangular line frame.

The display segments as described above form a unit display body, and are arranged in two rows in the horizontal direction, and the display surface of each segment arranged in one row in the vertical direction is colored in an arbitrary color such as red or blue. .

Display segments 35a arranged in a rectangular line shape
The corners of are notched diagonally, and 40 indicates the notch. Further, a portion of the display segment 35a corresponding to the display segment 35b is cut out to form a V-shape. 41 indicates the notch.

The display segments as described above can represent numbers 0 to 10 by changing their combination.

In the display device as described above, the present invention forms a display body in which a ¥ symbol segment 37 is combined with a linear segment 38 adjacent to the ¥ symbol segment 37 at the topmost digit of the display device 36, and a Dotted segment 3 in the middle of the unit display
9, which serves both as a time and price display.

The display state of FIG. 1 shows the time, and the display state of FIG. 2 shows the gasoline price.

The ¥ symbol segment 37 has display bodies arranged in a ¥ shape, and the linear segment 38 has display bodies arranged in a row, and the corners are diagonally cut out.
is the notch.

The center of the segment 38 is cut out to form a V-shape. 38b indicates the notch. The dotted segment 39 has two display bodies arranged in parallel.

As described above, the gasoline unit price and time can be displayed by reversing the display.

(Effect of the invention) According to this technical means, required characters and numbers can be reliably displayed by a combination of display segments made of magnetic reversal elements. In addition to the time display, the price of gasoline and the like can also be displayed, making it possible to achieve an economical display effect.

Since it is composed of display segments, a driver of a car driving on the road can clearly read the time or the price of gasoline, etc. even during the daytime, thereby providing better service to customers.

The top digit display consists of a ¥ symbol segment and a linear segment, so in the time display, along with other unit displays, the hour from 1 o'clock to 12 o'clock and the dotted segment are used to display the minute. is possible,
By using the ¥ symbol segment in combination with other unit indicators, prices can be displayed reliably and easily.
Since it is a time display, it can be incorporated in the space required for the segment of other unit display bodies, and the ¥ symbol can be displayed at the head to form a price display, making it possible to advertise without wasting space. A display body can be formed. Therefore, numbers or letters are easier to read outdoors, such as at a gas station, during the daytime than when display segments are made of magnetic reversal elements and are made of light emitting displays.
