An electronic pen cartridge is mounted on a mounting part disposed in a pen-shaped casing. The electronic pen cartridge includes an electronic pen main unit and a mounting adapter. The electronic pen main unit includes a first coupling part configured to connect the mounting adapter to the electronic pen main unit in an axial center direction. The mounting adapter includes a second coupling part connected to the first coupling part of the electronic pen main unit, a third coupling part connected to the mounting part of the casing, and an elastic component that causes an elastic force to act between the mounting adapter and the electronic pen main unit in a connected state in which the second coupling part is connected to the first coupling part of the electronic pen main unit.

A multifunction pen includes plural refills including an electromagnetic induction touch pen. A knock operation to one of knock rods each of which is connected to a rear end of each of the plural refills causes a tip of one refill of the plural refills to move from a standby position in which the tip stays inside a shaft tube to an in-use position in which the tip projects from a tip end opening of the shaft tube. At least one refill from writing refills other than the electromagnetic induction touch pen is provided with a metal writing tip, and a tip of the electromagnetic induction touch pen at the in-use position is separated from the tips of the writing refills at the standby position by a distance such that electromagnetic induction by the electromagnetic induction touch pen is not affected by the tips of the writing refills.

A two-color pen includes a pen body, a roller and water supply components; the roller is rotatably provided at the head of the pen body; there is at least one pair of water supply components, a reset device for pushing the water supply components to be in contact with the roller is provided in the pen body; and the roller is provided with a transmission part which alternatively pushes two water supply components in pairs in the direction away from the roller in sequence. The reset device in the two-color pen can push the water supply components outputting different colors in the direction of the roller. When the roller is rolling, the transmission part provided on the roller can alternately push the two water supply components in pairs in the direction away from the roller in sequence, so that the water outlet ends of the two water supply components in pairs can alternately abut against the roller in sequence under the action of the reset device. In this way, the roller can draw lines or patterns with two colors, thus better meeting the use requirements of users.

A writing instrument, in particular a pen, comprises a housing comprising a front barrel and a rear barrel, the front barrel having a front opening, two or more cartridges for storing colorants or inks, each cartridge having a writing tip, at least one actuator for selectively moving one of the cartridges within the housing so that the writing tip of a selected cartridge extends through the front opening of the front barrel, and a cartridge guide member which is designed to guide the movement of the cartridges within the housing. The front barrel and the cartridge guide member are designed to be removed from the rear barrel for replacing one or more of the cartridges. In particular, the front barrel and the cartridge guide member may be removed from the rear barrel while the cartridge guide member may remain mounted to the front member at the same time.

Proposed is multi-color marker pen which is composed of a cap (200) and a casing (100) covered by the cap (200). The casing (100) is composed of a linear shaft (110) covered by the cap (200) and having the shape of a hollow body, a sealing part (120) coupled to the upper part of the linear shaft (110) and having a guide (121) formed therein, and a button operation part (130) coupled to the upper part of the sealing part (120). A plurality of tubes (300) is provided in the casing (100), and the upper part of each of the plurality of tubes 300 is coupled to the sealing part (120) in which the guide (121) is formed. The button operation part is composed of three buttons, and by pressing the button operation part (130), the lower part of each of the tubes is ejected through a hole (111) formed in the lower end of the linear shaft (110). In addition, the casing (100) the linear shaft (110) covered by the cap (200) and having the shape of a hollow body, the sealing part (120) coupled to the upper part of the linear shaft (110) and having the guide (121) formed therein, and an operation handle (130) coupled rotatably to the upper part of the sealing part (120). The plurality of tubes (300) is provided in the casing (100), and the upper part of each of the plurality of tubes 300 is coupled to the sealing part (120) in which the guide (121) is formed, and due to the rotation of the operation handle (130), the lower part of each of the tubes is ejected through the hole (111) formed in the lower end of the linear shaft (110). Molten synthetic resin is injected into a mold (1000) composed of an upper mold (1100) and a lower mold (1200) so as to manufacture the casing, the cap, and the operation handle.
