Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a writing device such as a white board, bulletin board, message board, electronic blackboard, etc., which has a writing surface in a casing and can write information on it by handwriting.
[0002]
[Prior art]
For example, various types of electronic blackboards have been developed and used which allow a writing surface to be exposed from an opening window opened on the surface side of a casing supported by a leg and to write information on the writing surface. .
[0003]
For example, an electronic blackboard having a pen tray is known, and an erasing member such as a writing instrument or a blackboard eraser can be held there. By the way, in this electronic blackboard, when information is written on the writing surface with a writing instrument such as a water-based pen, an ink scum is generated and falls downward to contaminate the floor surface. The pen tray can receive the ink residue and prevent it from falling to the floor.
[0004]
[Problems to be solved by the invention]
However, in this electronic blackboard, the ink residue received by the pen tray may adhere to the writing tool again in the pen tray, and this may adhere to the writing surface and stain the writing surface. Therefore, in order to prevent such inconvenience, for example, as described in Japanese Patent Application Laid-Open No. 11-59071, a powder receiving member is provided directly above the pen tray so that the ink residue falls on the pen tray holding the writing instrument. The prevention is proposed.
[0005]
On the other hand, in such an electronic blackboard, characters and figures are usually written by hand, but there may be cases where, for example, a table or the like is desired. Usually, in such a case, it is difficult to create a clean table or the like because the writing tool is used and the freehand is used.
[0006]
In view of this, for example, as disclosed in Japanese Patent Application Laid-Open No. 10-29398, a special ruler bar is slidable in the lateral direction, and a writing instrument is detachably attached to the ruler bar.
[0007]
Therefore, considering this situation, we are also considering the development of a product that satisfies the two functions of preventing ink scum from scattering and preventing ink from re-staining on the writing surface due to reattachment to the writing instrument, and creating a clean table. Has been. For example, a simple combination of those described in the above-mentioned two publications is also being considered, but this complicates the mechanism, increases the number of parts, increases costs, and may increase the size. There is.
[0008]
In view of the above circumstances, the invention according to claim 1 can prevent troubles such as scattering of ink scum and re-fouling of the writing surface with ink scum by reattachment of the ink scum to the writing instrument. An object of the present invention is to make it easy to create a table and the like, and to make the mechanism simple, low-cost, and easy to downsize.
[0009]
Furthermore, for example, in addition to writing information on the writing surface, for example, postings such as various drawings and materials are posted on the writing surface. Usually, posting such postings is performed. As a means, a magnet or the like is used, and it is necessary to prepare such a magnet separately. In this case, the writing surface is, of course, limited to that made of a magnetic material.
[0010]
In view of the above circumstances, the invention according to claim 2 does not require a dedicated posting means such as a magnet, and the writing surface is not limited to a magnetic material but uses various materials. The purpose is to enable posting on the writing surface.
[0011]
In the invention according to claim 3, in the case where the receiving means such as a powder receiving member is used to receive the ink scum to prevent downward staining, the ink scum accumulated on the receiving means is easily removed. The purpose is to enable cleaning.
[0012]
Furthermore, when writing information etc. on the writing surface, there is a case where the writing quality of the writing instrument to be used is examined, for example, by searching for an appropriate flat surface other than the writing surface, etc. However, during use over a long period of time, ink writing marks may remain dirty and cannot be erased.
[0013]
In view of the above-described circumstances, an object of the invention according to claim 4 is to prevent each part from being soiled by test writing.
[0014]
Furthermore, for example, when erasing information written on the writing surface, static electricity is easily generated on the writing surface by repeatedly rubbing an erasing member such as a blackboard eraser against the writing surface. When the body or clothes touched it, it was uncomfortable, such as adsorbing and making a crackle, and sometimes causing pain in part of the body.
[0015]
Accordingly, an object of the invention according to claim 5 is to remove unpleasant static electricity so that it can be used comfortably.
[0016]
Further, along with the generation of the static electricity, the ink scum enters the writing device through a gap between the writing surface and the casing, and enters a mechanism portion such as a moving mechanism of the screen sheet as the writing surface. There is a problem that it adversely affects the transportation of the machine.
[0017]
In view of the above, an object of the present invention is to prevent ink dregs from entering the writing device due to static electricity.
[0018]

As shown in FIGS. 2 and 3, the pen tray 3 has a substantially L-shaped cross section and is integrally formed with the lower horizontal frame 12 (or a separate one is fixed with an adhesive or the like. ) It is located directly below the powder receiving member 4 and has an uneven portion formed repeatedly on the upper surface to hold the writing instrument P such as a water-based pen so as not to roll.
[0027]
The powder receiving member 4 which is processed separately from the housing 1 by extrusion molding is formed to have a size over the entire width of the exterior frame 1B and is movably attached to the left and right vertical frames 11. That is, as shown in FIG. 3, the powder receiving member 4 of this embodiment includes a holder 41 that is movable in the vertical direction while sliding on the vertical frame 11, and a shaft 42 that is rotatably attached to the holder 41. The main body 44 is pivotally attached to the shaft 42 via a compression spring 43.
[0028]
The holder 41 is substantially U-shaped that slides on a convex portion formed on the opposing surfaces of the vertical frames 11 facing each other, and an engagement hole 41A is formed in the center portion of the protruding surface. ing. Further, as shown in FIG. 5, in this holder 41, the foam member 41B is partially protruded to the outside in order to scrape and remove the ink residue adhering to the pen tip such as a water-based pen. A tank part 41C is provided.
[0029]
The shaft 42 includes a pin portion 42A into which a compression spring 43 is inserted with a small diameter at one end side, a hook portion 42C having a slit shape at the other end side and a large diameter flange 42B at the end portion, a pin portion 42A and a hook It has a boss part 42D protruding in an intermediate part with the part 42C.

A convex portion 44B is formed. Further, a flat portion 44 </ b> C that has a flat shape and captures ink scum falling from the writing surface D is formed between them. The flat portion 44C is formed flat without providing a convex portion in order to easily remove ink scum from the left and right ends so that it can be easily cleaned. A dedicated area 44D is formed.
[0031]
Further, as shown in FIG. 4, the main body 44 is provided with a brush member 45 in which a flocked brush 45A is implanted at the tip as a static electricity removing member and for prevention of ink scum scattering or ink scum fall. For example, it is fixed over the entire lower surface with a double-sided tape or the like. The brush member 45 is attached so that the tip of the brush 45A protrudes from the main body 44 with a length that touches the writing surface D. As the brush 45A in this example, a brush for removing static electricity such as carbon fiber or metal fiber is used.
[0032]
The main body 44 in this example is formed by extrusion molding, but is preferably formed of acrylonitrile / butadiene / styrene resin in consideration of the moldability and environmental problems. Further, the main body 44 is coated with the same color as the ink residue, or the same color system is used in advance so that the ink residue does not become conspicuous from the outside even if the ink residue adheres or accumulates. It is preferable to mold using a resin material. The color in this case is preferably dark in appearance, but an acrylic-treated material may be used to prevent ink adhesion and stain. On the other hand, a white sheet member may be attached to the dedicated area 44D to make the color different from that of the flat portion 44C.
[0033]
Next, how to assemble the powder receiving member 4 and how to attach it to the housing 1 will be described.

Next, the hook portion 42 </ b> C of the shaft 42 is inserted into the hole 41 </ b> A of the holder 41 so that the holder 41 can rotate.
[0034]
In this way, when the pair of left and right holders 41 are attached to the distal end portion of the shaft 42, the entire width of the left and right holders 41 is pushed into the main body 44 against the elastic force of the compression spring 43. It is attached so that the holder 41 is fitted between the left and right vertical frames 11 together with the main body in a narrowed appearance. As a method for fitting the holder 41, the shaft 42 may not be pushed into the main body 44, but may be fitted with the overall width narrowed by bending the main body 44.
[0035]
Next, various usage methods using the writing apparatus of this example will be described.
For example, when performing ruled line writing, for vertical lines, a writing implement such as an aqueous pen is held by hand on a part of the powder receiving member 4, and the holding position is not moved, and the powder receiving member 4 is left as it is. If you slide it up and down, you can draw one vertical line. Furthermore, if the holding position of the writing instrument is shifted by an appropriate interval and the same operation is performed, one more vertical line can be drawn at the appropriate interval. Hereinafter, similarly, a large number of vertical lines can be drawn at appropriate intervals.
[0036]
On the other hand, regarding the horizontal line, if the main body 44 of the powder receiving member 4 is fixed at a desired position and an aqueous pen or the like is moved along the upper edge of the main body 44, one horizontal line can be drawn. Further, the powder receiving member 4 is slid in the vertical direction by an appropriate interval, and in the same manner, one horizontal line with an appropriate interval can be drawn. Hereinafter, similarly, a large number of horizontal lines can be drawn at appropriate intervals.
[0037]
Thus, if a line is drawn in either the vertical or horizontal direction, a desired ruled line can be written, and a desired table can be formed by drawing the line in both the vertical and horizontal directions.
[0038]
