Abstract
Description
Technical Field
[0001] This invention relates to a handy and erasable portable memo device that can be semi - permanently reused. On both the front and back writing surfaces, when memos are made with a whiteboard marker, the written characters and the like can be easily erased, and new memos can be written in the erased space. It is made of a suitable material such as glass or a whiteboard sheet that can be written on and erased with a whiteboard marker.
Background Art
[0002] Conventionally, when making daily ideas, information, etc. within a home or office, or making a shopping list, etc., the common method was to write with a writing instrument on memo paper or the like.
Summary of the Invention
Problems to be Solved by the Invention
[0003] The means of making memos on conventional memo paper has the following problems. (1) The memo - written paper is difficult to reuse repeatedly, and new paper is required one after another, resulting in waste of resources and being uneconomical. (2) When multiple items are memo - written on a single memo paper, it is not easy to erase the used memo in the limited space of the paper and write new memos. (3) Each sheet of memo paper is usually placed flat on a table, desk, etc., so it is not very conspicuous. (4) The writing instrument for making memos is usually stored in a different place from the memo paper, so it is inconvenient for immediate memo - writing.
Means for Solving the Problems
[0004] In this invention, both the front and back writing surfaces for making memos are It is made of a suitable material such as glass or a whiteboard sheet that can be written on and erased with a whiteboard marker, and the writing surface This portable memo pad is characterized by its ability to be used almost indefinitely, as notes written with a whiteboard marker can be easily erased by wiping with a fingertip, tissue paper, or cloth, and new notes can be written in the erased space. Furthermore, because this memo pad has a moderate hardness and thickness, it can be placed in a memo pad stand and held upright on a table or desk, making it easy to see. A whiteboard marker holder is provided on the back of the memo pad body, so the whiteboard marker can be held there and held integrally with the memo pad, making it convenient for quick note-taking. [Effects of the Invention]
[0005] As described above, the portable memo pad of this invention, which can be written on and erased, has writing surfaces on both the front and back. It is made of a suitable material such as glass or a whiteboard sheet that can be written on and erased with a whiteboard marker. Since you write notes on this with a whiteboard marker, you can easily erase used notes by lightly wiping them with your fingertip, tissue paper, or cloth, and then write new notes in the erased space. This allows you to reuse one memo pad almost indefinitely, making it economical and conserving resources. Furthermore, the memo pad itself has a suitable hardness and thickness, so it can be placed in a memo pad stand and held upright on a table or desk, making it easily visible. A whiteboard marker holder is provided on the back of the main body, allowing you to hold a whiteboard marker, which is convenient for quick note-taking. [Brief explanation of the drawing]
[0006] [Figure 1] This is a perspective view showing one embodiment of the portable memo device of the present invention, which allows writing and erasing, with the cover open. [Figure 2] This is a perspective view showing the structure of the memo writing surface, the structure of the back of the memo device that holds the memo writing surface, and the structure of the whiteboard marker holder installed on the back of the memo device, of the portable memo device that can be written on and erased according to the present invention. [Figure 3] This is a perspective view showing one embodiment of the portable memo device of the present invention, which allows writing and erasing, with the cover closed. [Figure 4]This is a plan view showing one embodiment of the portable memo device of the present invention, which allows writing and erasing, with the cover closed. [Modes for carrying out the invention]
[0007] The embodiments of the present invention will be described below with reference to the attached drawings. The following embodiments are illustrative examples for explaining the present invention and are not intended to limit the present invention to these embodiments only. Furthermore, the present invention can be modified in various ways without departing from its essence. [Examples]
[0008] A rectangular board 2, small enough to be easily held in the palm of one hand, is made of a suitable material such as thick cardboard with white on both sides. Transparent glass plates 3 are bonded to both sides of the board 2, and the transparent glass plates 3 are fixed to the white board 2 to form a single unit with the white board 2 and the transparent glass plates 3, which constitutes the memo writing board 1. A back member 6, made of a suitable material, has a recess 4 and a flat back surface 5, for holding one side of the long side of the memo writing board 1. The long side of the memo writing board 1 is fitted into the recess 4 of the back member 6 and secured with adhesive or other suitable means to form the back of the memo holder 7. The flat bottom surface 8 of a pipe 9, made of a suitable material, has an inner diameter that can accommodate a whiteboard marker, and has a flat bottom surface 8, is bonded to the flat back surface 5 of the back of the memo holder 7 with adhesive or the like to form the whiteboard marker holder 10. To prevent writing on a whiteboard marker from being erased by contact with external materials, transparent covers 11a and 11b made of appropriate materials such as plastic are attached to both the front and back surfaces of the memo writing board 1 with transparent adhesive vinyl tape 12 or the like, so that the transparent covers 11a and 11b can be opened and closed. Furthermore, to prevent the transparent, openable covers 11a and 11b from coming into contact with the written writing and erasing it, protrusions 13 are attached to the top and bottom centers near the edges of the front and back surfaces of the memo writing board 1, creating a certain gap between the memo writing surface and the transparent covers 11a and 11b. [Industrial applicability]
[0009] The portable memo device described in this invention, which allows for easy and repeated writing of daily notes using only one device, is economical, easy to use, and contributes to resource conservation in the long term. Therefore, it is expected to replace conventional memo paper and become the mainstream method of note-taking in the future. [Explanation of symbols]
