Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a bulletin board using a surface light emitter.

[0002]

[Prior art]

 In recent years, a display board using a surface light emitter such as an EL (electroluminescence) lamp has been receiving attention. In general, this type of bulletin board is constructed so that characters and patterns written on the surface of the surface light emitter with a felt-tip pen or the like are conspicuously displayed by the surface light emission from the back, and the surroundings are dark. The effect of posting can be exhibited, and if the contents of the bulletin change, it is easy to rewrite only the necessary part. However, since it is entirely handwritten, the displayed contents are likely to be slightly displayed, and it is not suitable for creating a large number of the same items. There is a problem that the pattern is easily rubbed and disappears.

On the other hand, in the conventional one known in Japanese Utility Model Laid-Open No. 4-3482, a bulletin board on which all necessary characters and patterns are printed is placed on the front surface of the surface light emitter. Since it has a structure that is integrated into one unit, it is possible to display a high-quality display of specific bulletin boards for a long period of time. Moreover, since the above-mentioned bulletin board is a printed matter, other members such as surface light emitters are procured. If possible, you can easily create the required number of bulletin boards with the same content.

[0004]

[Problems to be solved by the device]

 However, in the above-mentioned conventional example, if even some of the bulletin board contents are changed, a new bulletin board sheet must be printed even if the bulletin board contents are of the same kind, and the bulletin board sheet can be replaced. The bulletin board must be disassembled and reassembled. In other words, even a slight change in the posted content takes time and effort, and in practical use, there is a problem that the bulletin board lacks the mobility and versatility.

For example, when considering the case of posting a guide for overnight attendance at a funeral, the same type of posted content, “tour guide for overnight attendance”, is generally different on the bulletin board except for individual items such as house name, place, date and time. Many other characters are common. However, in the above-mentioned conventional example, the bulletin board must be printed and the bulletin board must be disassembled and assembled every night.

The present invention has been made in view of the above points, and an object thereof is to deal with a change in the posted content with a little effort and time, and moreover, it is not a completely handwritten one. It is to be able to post with a high-class feeling.

[0007]

[Means for Solving the Problems]

 In order to achieve the above object, in the present invention of claim 1, a plurality of types of bulletin sheets in which common matters are printed in advance are selected and used, and individual matters are added to the transparent plate by handwriting or the like.

Specifically, in this invention, a frame body having an opening at least on the front surface side, a transparent plate provided on the front surface side of the frame body so as to cover the opening portion, and a rear surface side of the frame body. The surface light emitters are arranged so that a space for inserting a bulletin board is formed between the transparent plate and the transparent plate, and a common item corresponding to the type of bulletin board is displayed in advance. A configuration is provided that includes several types of bulletin sheets and a bulletin sheet entry / exit portion that is provided in the frame body and that inserts / extracts the bulletin sheet into / from the bulletin sheet insertion space.

According to a second aspect of the present invention, in the first aspect of the present invention, the surface light emitter is formed of an EL lamp.

Further, in the invention of claim 3, in the invention of claim 1 or 2, the frame body is configured to have a main body frame and a detachable frame detachable from the main body frame. The part corresponding to the attaching / detaching frame constitutes a bulletin sheet inserting / extracting part which is opened / closed by attaching / detaching the attaching / detaching frame.

[0011]

[Action]

 In the invention of claim 1, the bulletin board selected according to the type of the bulletin board is inserted into the bulletin board bulletin board insertion space of the frame through the entry / exit section, and in that state, only individual items such as date and time and place are transparent. By adding by handwriting, etc. to the part corresponding to the blank part of the above-mentioned notice sheet on the surface of the board, the printed common items and individual items added by handwriting etc. are displayed by the surface light emitter.

[0012] When individual items are changed with the same type of bulletin contents, for example, when the bulletin contents are the same type such as "night notice", but the target is changed from the A house to the B house this time. You can change the individual items such as house name, place, date and time from those of House A to House B with the bulletin sheet still inserted. In addition, when changing the type of the bulletin board from, for example, “night notice” to “separation ceremony guide”, select the “separation ceremony guide” notice sheet and select the “night notice” notice sheet. The transparent sheet may be replaced and individual items may be added to the transparent plate. At this time, the posting sheet can be easily replaced through the posting sheet entry / exit of the frame.

According to the second aspect of the present invention, since the surface light emitter is composed of the EL lamp, the EL lamp is thin, light, durable, has a freedom of shape, does not generate heat, and is uniform. By utilizing various features such as obtaining a light emitting surface, it is possible to obtain a bulletin board that is compact and easy to handle, is safe without the risk of overheating during light emission, and has no unevenness in brightness or darkness over the entire surface of the posted content.

Further, in the invention of claim 3, the frame body is composed of a main body frame and a removable frame detachable from the main body frame, and the frame body is provided at a portion corresponding to the removable frame. Slits, etc. are provided in the frame body by constructing a bulletin sheet entry / exit portion that is opened and closed by the attachment / detachment of the detachable frame, that is, by defining a part of the frame body as a missing portion and constructing the bulletin sheet entry / exit portion by this missing portion. As a result, a large bulletin sheet loading / unloading section can be provided more comfortably than in the case where the loading / unloading section is configured, and therefore, the bulletin sheet replacement work can be facilitated. Further, in a state in which the removable frame is attached to the main body frame and the entry / exit portion is closed, the missing portion of the frame body is compensated and the outer shape of the frame body is restored to the original state.
