Description

[Detailed description of the invention] (A) Industrial application field The present invention is an improvement of a writing board made by holding a board sheet on which figures, characters, etc. are drawn, and is mainly used in blackboard type electronic copying machines. This paper relates to a portable writing board used in a central office automation system.

Recently, blackboard-type electronic copying machines have been developed as OA equipment, but if one blackboard-type electronic copying machine is used by multiple departments or sections, the amount of time it can be used is limited.

Therefore, it has been desired to develop an OA accessory that has the same functions as a blackboard and can also function as a terminal when a blackboard type electronic copying machine is set as a host.

The present invention is a portable writing board provided for the above purpose.

(B) Prior Art Conventionally, there have been several types of articles called writing boards.
However, they were either stand type or hanging type. Therefore, in this respect, its utility as a terminal was poor.

Furthermore, writing boards have a surface sheet of paper, etc., but unlike a blackboard, they are not intended to be erased, so there is no way to prevent the sheets from moving due to the force of erasing, and it is difficult to put in and take out the sheets. , it was hard to say that it was easier than removing it and not intending to use it again.

Furthermore, in the case of hanging writing boards, no mechanism was provided to prevent them from rattling between them and the wall surface.

(C) Problems that the present invention aims to solve Therefore, the present invention aims to solve the following points.

First, it must be portable to ensure its usability as a terminal.

Second, the handle and the like at that time should not be inconvenient to use or wasteful in terms of design.

Thirdly, when erasing written characters, the board sheet does not move and does not curl.

Fourthly, it is easy to take in and out the board sheet.

Fifth, it should not wobble when used on a wall.

(D) Means for Solving the Problems In order to solve the above-mentioned problems, the present invention attaches an edge to the periphery of the board so that it protrudes beyond the back surface of the board, and partially removes the edge at the center of the top edge of the board. A handle with the same shape as the edge is attached to the notch so that the handle support can be buried in the board and pulled out to a certain height, and the desired number of sheets are placed between the top and bottom sides of the board surface. A plate sheet receiving plate is provided with a space equal to the thickness of the plate sheet, and a sheet holding spring is installed between the board and the plate sheet receiving plate so that the plate sheet can be inserted on the board side. The purpose is to provide a portable writing board for writing.

(E) Effect In this invention, when the plate sheet is inserted between the sheet presser springs in the upper and lower plate sheet receiving plates and the board, the plate sheet is pressed and held against the board by the sheet presser springs. Ru.

When carrying the present invention, pull out the handle and hang it on a wall using a separate hanging device, and push the handle in when using the device. In this case, the edge and the handle are at the same height, and only the edge touches the wall, not the board itself.

(F) Example The illustrated embodiment will be described below.

FIG. 1 is a front view showing the present invention, FIG. 2 is a partially cutaway sectional view.

In both figures, 1 is a portable writing board according to the present invention, 2 is an edge, 3 is a substrate, 4 is a handle, 5 is a powder catcher, and 9 is a plate surface sheet receiving plate at the upper end. Note that 6 is an end cover attached to the notched end of the edge 2.

The edge 2 is attached to the periphery of the substrate 3 with rounded corners. In the embodiment, the edge 2 is a thick rubber edge that protrudes outward from the back surface of the substrate 3.

A portion of the edge 2 at the center of the upper end of the board 3 is cut out, and a handle 4 having the same shape as the edge 2 is attached to the cutout.

FIG. 3 is a partially enlarged sectional view showing the upper end of the present invention, and the handle 4 has a handle support 8 buried in the space of the base plate 3 and pulled out to a certain height (to the extent that a hand can be inserted). It is installed so that

Reference numeral 9 in FIG. 3 is a plate sheet receiving plate, which is mounted along the upper edge of the surface of the board 3 with a space equal to the thickness of the desired number of plate sheets between it and the surface of the board 3. A sheet presser spring 7 made of a plate spring is installed between the sheet receiving plate 9 and the substrate 3.

FIG. 4 is a partially enlarged cross-sectional view showing the lower end of the present invention, where a powder catcher 5 and a sheet receiving plate 9 are present.

Note that the plate-faced sheet receiving plate 9 at the lower end is formed integrally with the powder receiver 5, but except for the plate-faced sheet receiving plate 9 located at the upper end side of the surface of the substrate 3, It has the same configuration as .

(G) Effects of the invention Since the invention works as described above, it has the following effects.

First, since the present invention has a handle 4, it is convenient to carry, and the handle 4 itself has the same shape as the edge 2.
By burying it to the same position, we were able to eliminate inconvenience and discomfort in the design when using it.

Second, unlike conventional writing boards, the board sheet is held not only at the top edge but also at the bottom edge, which prevents the board sheet from curling and when erasing written characters, etc. I no longer have to move around anymore.

Thirdly, when using the present invention on a wall or desk surface, only the edge 2 part comes into contact with the wall surface, etc., and the board 3 does not come into contact with it, so there is no play even in such use. It never occurs.

Fourthly, even when attaching or removing the plate sheet, since the present invention presses and clamps the plate sheet with the sheet holding spring 7, it is only necessary to insert or pull out the plate sheet, making it extremely easy to handle. be.

Fifth, because it has the effects described above, it can serve as a terminal for blackboard type electronic copying machines.
It has become possible to use it as part of an OA system.

An example of this will be briefly explained with reference to the diagram shown in FIG.

First, the present invention is used by the sales department and planning department of a branch office, which are small units, to create a board sheet AB. These are made into copies of appropriate sizes using a blackboard type electronic copying machine.

This will be sent to the head office by fax.

The fax original is copied onto projection film at the head office. While projecting this projection film AB onto a blackboard-type electronic copying machine board sheet using a projector, corrections and additional proposals are added. Then, only the revised draft, etc. that has only been added will be generated as a copy CD.

By overlapping and copying this copy CD and the previously generated projection film AB, the completed materials A+C and B+D are completed.
