However, in the technique of Patent Document 1, a specific method for attaching the pen tray to the rubber magnet is not disclosed, and it is usually interpreted that the pen tray is attached by adhesion or the like. Since care must be taken to prevent the agent from sticking out, soiling, and the position of the pen tray being displaced, inconveniences in productivity are likely to occur.
In addition, it is possible to imagine a configuration in which the pen tray is attached to the rubber magnet by magnetic attraction, but in this case, the pen tray must be made of a ferromagnetic material such as a steel plate, In addition, there is a need for a process that does not cause sharp burrs and the like, and there is a technical problem that a sufficient magnetic attraction force must be ensured so that it does not move easily when it comes into contact with the pen tray.

  Moreover, in the technique of patent document 2, in order to insert the support piece for flat-plate-shaped pen holders in the form provided in the cursive body so that the flat plate surface may become vertical, it matches the upper end surface. If it is not a pen of the form to be placed, there is a disadvantage that it is difficult to place and easy to fall, and because the end surface of the support piece for pen placement is inserted against the writing body, if a load is applied to the support piece for pen placement The inconvenience in strength that the end face is likely to bite and be damaged is expected.

  Therefore, in order to eliminate the disadvantages in the prior art, the present invention is easy to mount the receiving member, can be reliably placed on a pen, etc., and can secure a stable mounting strength. It is another object of the present invention to provide a magnetic adsorption type board with a receiving member excellent in performance.

In order to solve the above-mentioned problems, the present invention is a result of earnest examination of utilizing the action of magnetic attraction force that attaches the board to the ferromagnetic article without using the structure of the board in which the receiving member is attached from the beginning. More specifically, the magnetic adsorption type board is composed of a magnetic adsorption type board made of a magnet sheet and a receiving member that is flexible and can be magnetically adsorbed to the back side of the ferromagnetic article. Is formed with a punching portion penetrating from the front surface to the rear surface, and the receiving member has a horizontal or upward inclined surface or an accessory receiving portion having a substantially L shape, and a vertical upper retaining portion provided at the rear portion thereof. or lower retaining portion, or in the upper retaining portion and the lower retaining portion is formed, the receiving member, relative to the punching portion of the magnetic entrapment board receiving portion escapes the accessories Not be, and, along with it inserted and locked as downward movement of is blocked from its locked state, when obtained by magnetic attraction to the ferromagnetic article the back of the magnetic entrapment board retaining portion Is prevented from descending on the lower surface of the punched portion, and the upper retaining portion, the lower retaining portion, or the upper retaining portion and the lower retaining portion formed there are flexible magnetic The adsorption board is flexibly deformed so that the entire surface is held between the ferromagnetic articles .

By adopting such a configuration, the receiving member is not attached to the magnetic adsorption type board from the beginning, so the product is simply packaged as a disassembled member. Since it is only necessary to insert directly from the back side of the magnetic adsorption type board, it can be easily performed .

  In addition, the receiving member is in a state in which it is prevented from descending when the magnetic adsorption type board is attached to the ferromagnetic article by magnetic adsorption while passing through the accessory receiving part of the punched part from the back of the magnetic adsorption type board. Therefore, the upper retaining portion, the lower retaining portion, or the upper retaining portion and the lower retaining portion enter between them, and the magnetic adsorption type board is formed of a flexible magnet sheet, so that it deforms flexibly. By doing so, the entire surface is held in a sandwiched state between the magnetic adsorption type board and the ferromagnetic article, so that although it is indirect, it is securely attached.

  In addition, it can implement by forming in the surface of a magnetic adsorption type board the writing layer which can write in and erase | eliminate the felt pen which uses aqueous and / or alcoholic ink.

  And, in the accessory receiving part formed on the receiving member, a notch and / or a protrusion can be formed, and in this way, accessories such as rubber bands are also hooked, Convenience can be improved.

According to the present invention, although it has a simple configuration, it is possible to reliably place a pen or the like, and to finish a magnetic adsorption type board with a receiving member having a receiving member with a stable mounting strength.
Therefore, the product can be finished as a product with high productivity and low production cost.
Further, since the receiving member is not directly fixed to the magnetic adsorption type board, the magnetic adsorption type board can also be used in a simple form without the receiving member.
