[0006] The present invention is a multifunctional stationery device comprising a central housing, multiple writing instrument modules detachably connected to one side of the housing, and multiple auxiliary instrument modules detachably connected to the other side. Each module has a magnet at one end, which magnetically attracts and connects it to the housing and other modules. This structure allows users to selectively separate any module and quickly and easily combine and use the desired functions. This allows for a variety of writing and auxiliary functions to be realized in a single stationery device, improving user convenience. Furthermore, the magnetic attachment / detachment mechanism allows for quick and reliable connection and disconnection compared to conventional screw-type or snap-type attachments, and is also superior in durability and ease of maintenance. Therefore, the present invention provides a means to significantly improve the flexibility and convenience of multifunctional stationery devices.

[0007] The purpose of this invention is to provide a multifunctional stationery item that allows users to easily reverse the polarity of a magnet. Specifically, a depressible button is provided on the housing, and pressing this button rotates the internal magnet, thereby reversing the polarity of the magnet. This configuration allows users to change the polarity of the magnet with a single touch, without the need for special tools or complicated operations, greatly improving convenience. This increases the practicality and usability of this multifunctional stationery item, and it is expected to be used in a variety of applications.

[0008] This invention is a multi-function stationery device that incorporates a spiral spring inside a depressible button, creating a cam mechanism that rotates a magnet when pressed. This allows the spiral spring to efficiently store energy when a user presses the button, and then uses that energy to rotate the magnet.

It would be even better if the shape could be changed so that it could be stored together with other stationery items. The advantage of using magnets to connect the modules is that the modules can be easily removed and replaced, allowing for quick access to the necessary writing implements and auxiliary tools and for changing the combination.

[0013] The housing serves as the central link between the writing instrument module and the auxiliary tool module, holding the entire unit in place. By reversing the polarity of the magnet, the magnetic attraction of specific modules can be released, allowing them to be selectively separated. This allows for the removal of only the modules needed. A depressible button reverses the polarity of the magnet; by pressing the button, the magnet rotates, changing the polarity and altering the module connection state. This multi-functional stationery design is particularly suitable for students and business professionals, who may need multiple writing instruments and auxiliary tools for classes and exams. This product allows them to be stored and carried compactly.

[0014] For businesspeople, this product allows them to consolidate all the tools they need for meetings and taking notes on the go, enabling them to work more efficiently. Once launched, this product is expected to have competitive advantages such as compactness, customizability, unique design, and time-saving features. These features will differentiate it from other writing instrument storage products and make it an attractive option for users. This invention is a multifunctional stationery device in which a writing instrument module and an auxiliary instrument module are detachably connected to a housing via a magnetic connection. It features compact storage of writing instruments and auxiliary instruments and magnetic connection for convenient portability. Furthermore, a button on the housing allows the polarity of the magnet to be reversed, allowing specific modules to be selectively separated. While prior art documents focus on color expression, this invention emphasizes the convenience of storing and carrying writing instruments and auxiliary instruments. Furthermore, while the prior art focuses on a mechanism for changing ink color, this invention focuses on a mechanism for attaching and detaching modules via magnetic connection.

[0172] This image shows the structure of a writing instrument with a push button at the tip of a mechanical pencil or red ballpoint pen, which can be operated to change the pen's orientation. Specifically, it operates as follows: 1. The mechanical pencil or red ballpoint pen has a button on the top that can be pressed to change the pen's orientation. Pressing the button shown in the image rotates the tip, allowing it to change position. 2. To operate the instrument, prepare a writing instrument with the structure shown in the image, and press the button to activate the internal mechanism, causing the tip of the writing instrument to rotate. This action allows you to switch between different types of pens or mechanical pencils. 3. Furthermore, if the selected pen type has an eraser or other feature attached to the top, the eraser can also be used by operating it. The image also explains the specific mechanism, including how the actual writing instrument is assembled and how its parts interact. This provides the convenience of being able to have multiple functions in a single writing instrument.

[0173] The mechanism for reversing the magnet's polarity is achieved by incorporating a precision mechanism inside the stationery. First, the magnet placed inside the stationery is designed to rotate around a specific axis. This rotation mechanism consists of a housing that holds the magnet and a gear and cam attached to its exterior. Pressing the button activates these gears and cams, causing the magnet to rotate on its own. As the magnet rotates, its north and south poles reverse, changing the direction of the magnetic force. This mechanism uses high-precision bearings and low-friction materials for smooth and reliable operation. Furthermore, the magnet itself is made of powerful neodymium magnets, providing ample magnetic force despite its compact design. This ensures stable holding power at the connection point and allows for easy release when necessary. To ensure high reliability and durability while providing the flexibility of a multifunctional stationery, safety considerations were also necessary. Features include a locking mechanism to prevent accidental operation and rotation speed control according to usage conditions. This meticulous technical design allows this multifunctional stationery to meet diverse user needs, while its convenience and reliability make it ideal for everyday use. This configuration creates value beyond mere stationery and offers a new user experience.

[0174] The depressible button in this invention is designed for manual operation. When a user presses it with their finger, an internal helical spring compresses. This spring is a key element for efficiently transmitting the pressing force. When the spring compresses, the force is used to drive a cam mechanism. The cam mechanism converts the spring's compression energy into rotational motion. This causes the internal magnet to rotate in a certain direction, and this rotation generates a physical change caused by the magnet. While the change in magnetic field is another important aspect of this device, this description does not focus on the generation of an electrical signal. Instead, the focus is on the magnetic field change itself and the resulting mechanical action, such as triggering other mechanical components or controlling the entire device. In this way, the combination of the spring and cam mechanism is highly efficient and designed to smoothly execute a series of actions through button operation. As a result, this mechanism improves the overall operability of the device and allows for intuitive user operation. All of this combines to play an important role in manually controlled devices.

[0175] This invention involves placing an iron button on the top of a mechanical pencil, blue or red pen, or name pen, and by pressing this button, the orientation of the internal magnet can be changed. In addition, the ruler is folded in thirds to make it roughly the same size as a mechanical pencil, etc., so that it can be attached to these writing implements. Furthermore, for stationery items such as erasers, lead cases, and rolled sticky notes that are placed on top of pens, a gap is created in the adhesive part, a hole is formed there to fit an iron button, and a magnet is placed at the back of the hole. This creates a structure that allows for reliable attachment even when the button is present (see Figure 15).
