  The present invention relates to an information display device, an information display panel, a display lamp, and an information display method for displaying various types of information.

  Display boards and display devices that display various types of information include not only traditional blackboards and whiteboards that contain information written by hand, but also electronic bulletin boards with a large number of light bulbs and LEDs (Light Emitting Diodes), and liquid crystal displays. There are display devices using organic EL (Electro-Luminescence) or the like (for example, see Patent Documents 1 and 2).

JP 2001-117536 A (FIG. 1) JP 2004-69774 A (FIG. 1)

However, since blackboards and whiteboards are hand-written with information, they cannot be said to be aesthetically pleasing to use, for example, for the purpose of attracting customers or providing guidance. It is difficult to do.
On the other hand, in an electronic bulletin board, a display device using liquid crystal / organic EL, etc., it is excellent in aesthetics, and it is easy to make a specific portion stand out by blinking display, color display, or the like. However, these electric display panels and display devices are expensive. Further, since it is necessary to input display contents in advance, it takes time to input, and it is not easy to change the information to be displayed.
The present invention has been made on the basis of such a technical problem, and is an information display device, an information display panel, a display lamp, and an information display method capable of changing display information flexibly at low cost. The purpose is to provide.

For this purpose, the information display device of the present invention includes an information display unit that displays basic information and a display lamp that can be attached to an arbitrary position on the surface of the information display unit. And the information display part has the electroconductive 1st electroconductive part, the electroconductive 2nd electroconductive part, and has insulation, and was arrange | positioned between the 1st electroconductive part and the 2nd electroconductive part. An insulating part and a power source that generates a potential difference between the first conductive part and the second conductive part are provided. On the other hand, the display lamp includes a first electrode member and a second electrode member that can be inserted into the information display unit from the surface of the information display unit. The first electrode member and the second electrode member are electrically connected to the lamp body. In such an information display device, the first electrode member and the second electrode member of the display lamp are connected to the information display unit. When stabbed from the surface, the first electrode member can be electrically connected to the first conductive portion, and the second electrode member can be electrically connected to the second conductive portion. In this state, when a potential difference is generated between the first conductive part and the second conductive part from the power source, a voltage is applied to the lamp body through the first electrode member and the second electrode member, and thereby the lamp body is turned on. To do.
In the present invention, it is not necessary to form holes for inserting the first electrode member and the second electrode member in advance on the information display unit side, the first electrode member and the second electrode member. May be formed of a material that can be inserted into an arbitrary position. Thus, in the information display device of the present invention, the display lamp can be turned on only by inserting the first electrode member and the second electrode member of the display lamp into the information display section, and wiring and the like can be performed. There is no need to do it.

By the way, in such an information display device, the first conductive portion and the second conductive portion can be provided side by side along the surface of the information display portion via an insulating portion. However, in that case, the position and orientation of the display lamp (orientation in the rotational direction) is required to pierce the first electrode member of the display lamp into the first conductive portion and pierce the second electrode member into the second conductive portion. Will be limited.
On the other hand, it is effective that the information display unit has a configuration in which the first conductive unit, the insulating unit, and the second conductive unit are stacked. If it does in this way, if it is in the range where the 1st electroconductive part and the 2nd electroconductive part are laminated | stacked, a display lamp can be arrange | positioned in arbitrary positions. However, in this case, for example, when the first electrode member penetrates the second conductive portion and then reaches the first conductive portion when the first electrode member is inserted, the first electrode member includes It is preferable to provide an insulating coating for preventing a short circuit with the two conductive portions. Conversely, when the second electrode member is inserted, the second electrode member is prevented from being short-circuited with the first conductive portion when reaching the second conductive portion after passing through the first conductive portion. It is preferable to provide an insulating coating. Of course, an insulating coating may be provided on both the first electrode member and the second electrode member.

  Now, as described above, in order to insert the first electrode member and the second electrode member of the display lamp into the information display unit, the first electrode member and the second electrode, such as the first conductive unit and the second conductive unit. The portion where the electrode member is inserted is preferably formed of a material having elasticity, such as a rubber-based material. Moreover, after pulling out the first electrode member and the second electrode member, the holes approach the original state due to the elasticity of the material so that the holes formed in the portions where they are inserted are not noticeable. It is preferable to restore. Further, in order to make the holes inconspicuous, a cloth, a polystyrene foam, a sponge-like material or the like having a certain thickness may be pasted on the surface of the information display portion.

  In such an information display device, it is preferable that a sheet on which basic information such as a map, various lists, tables, graphs, and the like is described can be detachably attached to the surface of the information display unit. And it becomes possible to display information in the state excellent in visibility by attaching and lighting a display lamp in the arbitrary positions on a sheet | seat.

  Further, if the information display device further includes a controller for adjusting a potential difference generated between the first conductive portion and the second conductive portion by the power source, the brightness of the light emitted from the display lamp can be adjusted, or the display can be adjusted. The lamp can blink.

  Furthermore, in the information display unit, the first conductive unit, the second conductive unit, and the insulating unit can be provided by being electrically divided into a plurality of areas. The controller can apply a voltage between the first conductive portion and the second conductive portion independently in each of the plurality of areas. Accordingly, the brightness of the display lamp can be changed for each area, and the lighting and blinking timing can be varied.

  In addition, in the information display unit, a plurality of first conductive units can be provided by being stacked while being electrically insulated from each other. In this case, the display lamp is provided with a plurality of types of first electrode members having different lengths so that the first electrode member can be electrically connected to any one of the plurality of first conductive portions ( prepare). As a result, the first conductive portion to be electrically connected differs depending on the type of the display lamp. By controlling the voltage application to each first conductive portion with the controller, the brightness of the display lamp can be changed for each type of display lamp, and the timing of lighting and blinking can be varied.

  By the way, although it is preferable that the information display part is panel-shaped, it is not restricted to this. For example, the information display unit can be incorporated as a part of another device or structure. In that case, an apparatus or a structure incorporating the information display unit can be used as the information display apparatus in the present invention.

The present invention can also be understood as a single information display panel. The information display panel includes a first conductive layer having conductivity and elasticity, a second conductive layer having conductivity and elasticity, an insulating property and elasticity, and includes a first conductive layer and a second conductive layer. An insulating layer disposed therebetween, a power source that generates a potential difference between the first conductive layer and the second conductive layer, and a sheet holding layer that holds the sheet, the first conductive layer, the second conductive layer, The insulating layer and the sheet holding layer are provided by being stacked, and a pin can be inserted.
Here, a display lamp having a pair of two electrode pins has a state in which one electrode pin is electrically connected to the first conductive layer and the other electrode pin is electrically connected to the second conductive layer. It can be inserted into the display panel. In this case, two pairs of electrode pins of the display lamp serve as the pins.
As a sheet held by the sheet holding layer, there is a sheet on which basic information is written or a sheet on which basic information can be entered. The sheet on which basic information is described is a sheet on which basic information is described in advance by printing or handwriting. In addition, a sheet on which basic information can be written refers to a sheet on which information can be written with a writing tool, such as paper or a white board. In the sheet holding layer, such a sheet can be held in a detachable state. That is, the sheets can be exchanged. This increases the versatility of the display panel.
Such a display panel can be used as the information display unit described above.

The present invention can also be understood as a single display lamp. In this display lamp, voltage is applied to a first electrode pin having a predetermined length, a second electrode pin shorter than the first electrode pin, and the first electrode pin and the second electrode pin. A light source that can be turned on and a cover that covers the light source are provided. Further, the display lamp is laminated with the first conductive layer and the second conductive layer insulated from each other, and the first lamp is applied to the power supply device in which a voltage is applied between the first conductive layer and the second conductive layer. The electrode pin and the second electrode pin can be inserted. In the state where the first electrode pin and the second electrode pin are inserted, the first electrode pin is electrically connected to the first conductive layer, and the second electrode pin is electrically connected to the second conductive layer. To be connected to.
At this time, the first electrode pin passes through the second conductive layer (and the insulating layer) and reaches the first conductive layer. For this reason, in order to prevent a short circuit with the second conductive layer, the first electrode pin is provided with an insulating covering portion for electrically insulating the second conductive layer while being electrically connected to the first conductive layer. It is preferable to provide. Of course, the second electrode pin can also be provided with a similar insulating coating.
The display lamp cover may be attached with a label that transmits light emitted from the light source and that can write predetermined information or has predetermined information. Accordingly, predetermined information such as symbols and characters can be clearly indicated by turning on the display lamp.

  By the way, in the present invention, the display lamp has a first electrode pin having a predetermined length and a pointed tip, and a second electrode pin that is shorter than the first electrode pin and has a pointed tip. It is also possible to grasp as a feature that includes a light source that can be turned on by applying a voltage to the first electrode pin and the second electrode pin, and a cover that covers the light source. As described above, the display lamp provided with the first electrode pin and the second electrode pin with sharp tips is suitable for being used by being inserted into the information display unit and the information display panel as described above. At this time, if the first electrode pin and the second electrode pin have a shape with a sharp tip, the tip does not necessarily have to be completely sharp, and the first conductive layer, the second conductive pin, The shape of the tip can be determined so that it can be easily inserted according to the material of the layer, the insulating layer, or the like.

  Further, the present invention can be understood as an information display method. In the information display method in that case, the first conductive layer having conductivity and elasticity, the second conductive layer having conductivity and elasticity, the insulation and elasticity, the first conductive layer and the second conductivity layer are provided. Basic information is described on the surface of an information display panel including an insulating layer disposed between the layers and a power source that generates a potential difference between the first conductive layer and the second conductive layer. Then, a display lamp having two pairs of electrode pins is inserted into the surface of the information display panel. At this time, one electrode pin was electrically connected to the first conductive layer, and the other electrode pin was electrically connected to the second conductive layer, whereby the display lamp was described on the surface of the information display panel. Can be lit on basic information.

  In the present invention, the basic information described on the sheet may be any information. The basic information may be information corresponding to information to be displayed by combining an information display unit or information display panel and a display lamp.

According to the present invention, the display lamp can be turned on only by inserting the display lamp into the information display section or the information display panel. At this time, the display lamp can be attached to an arbitrary position of the information display unit or the information display panel, and can be easily removed by pulling it out. Thereby, it becomes possible to display various information by arranging and lighting the display lamp at an appropriate position on the sheet describing the basic information.
Since the display lamp is detachable from the information display panel at an arbitrary position, it can be changed to an appropriate position on the sheet, and the information content to be displayed can be easily changed. Furthermore, the use of the information display panel can be easily changed by exchanging the sheet on which the basic information is described or rewriting the basic information described on the sheet.
In this way, the information display device and the information display panel can display information with excellent aesthetics and visibility. In addition, since the information display unit and the information display panel have a very simple configuration, they can be manufactured easily and at a very low cost.

Hereinafter, the present invention will be described in detail based on embodiments shown in the accompanying drawings.
