The multi pen dry erase marker consists of two to six color dry erase pens that are spring loaded into an ergonomic housing and designed to be used with one hand only. Changing of colors is easy to do by pushing a button to add a pen color. To remove a color the pen is pushed back into the housing which locks it back in place. The end cap of the marker has a large felt or sponge tip to easily erase using a standard whiteboard. A storage cap protects the pens from drying out when being stored.

A stylus for a touchscreen may comprise a barrel extending in a longitudinal direction, the barrel comprising a first end comprising an opening and a second end, the first end and the second end being, in the longitudinal direction, opposite to one another, and a first part and a second part, the first part including the first end and the second part including the second end, a first electronic tip received at least in part in the barrel and configured to have at least an in-use configuration in which the first electronic tip protrudes from the first part of the barrel through the opening, and an energy harvesting device comprising at least two of an energy harvesting element, a transducer, or an energy storage device.

A refill for writing implements has an ink reservoir tube (1) made of resin material and formed to be a straight cylinder and a writing tip (2) attached to one end of the ink reservoir tube (1), and a value of an expression of D.sup.4−(D−2t).sup.4 is selected to be 45 or greater, where D denotes an outer diameter of the ink reservoir tube (1) and t denotes a thickness of the ink reservoir tube (1). It is possible to secure the necessary storage amount of ink in the ink reservoir tube (1) without increasing the outer diameter thereof, and is also possible to provide a refill for a writing implement and a writing implement which allow one to keep writing comfortably without feeling of discomfort in writing.

Multifunction writing instrument comprising a body extending in an axial direction and housing at least two retractable writing elements and a ring portion movable in rotation. The ring portion having at least as many pairs of guide surfaces as retractable writing elements. The writing elements include buttons. Each button is configured to cooperate with a respective one of the pair of guide surfaces of the ring portion. Actuation of the button of a writing element facilitates movement of the writing element from the retracted position to the writing position and returns any of the other writing elements in the writing position to the retracted position, whereby at most, one writing element is in the writing position.

A writing tool includes a refill having an ink reservoir tube formed to be a straight cylinder whose wall thickness is less than 0.56 mm; and a writing tip or a relay member holding the writing tip attached to a first end of the ink reservoir tube, wherein the refill is detachably attached to a barrel, wherein in the refill, amounting strength between the writing tip or the relay member holding the writing tip and the ink reservoir tube is set higher than a mounting strength between the barrel and a connecting portion of the ink reservoir tube. There is provided a writing tool that can prevent the occurrence of a problem such as leakage of ink at a time of replacement of refills and perform replacement of refills smoothly.

A feeding pencil includes a main body including a main body barrel having a tubular shape, a front barrel detachably engaged with the main body barrel, and a cartridge disposed in the front barrel to receive a drawing material. The cartridge includes a tubular portion provided on a rear side of the cartridge, the main body includes an insertion portion provided on a front side of the main body and configured to be engaged with the tubular portion. When the cartridge is tilted from the main body, an engagement between the tubular portion and the insertion portion is released.

A multifunction pen is provided including a refill for a writing implement such as a ballpoint pen on a tip end side and including an electromagnetic induction-based electromagnetic induction refill on a rear end side such that there is no need to perform a switching operation between the writing refill and the electromagnetic induction refill. The multifunction pen includes a shaft tube 10 including openings at both of a tip end and a rear end, a writing refill 40 that is housed inside the shaft tube 10 and that includes a writing tip exposed through the opening at the tip end, and an electromagnetic induction refill 50 that is housed inside the shaft tube 10, that is exposed through the opening at the rear end, and that is employed in electromagnetic induction-based input.

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.

An electronic pen includes an ink writing section including a core body and an ink holding section configured to hold an ink that is supplied to the core body, a circuit board, a transmission section which, in operation, transmits a signal, a connection member including a first side that holds an end portion of the ink writing section, on a side of the ink writing section opposite to the core body, and a second side that holds a first end portion of the circuit board, a pen pressure detector provided adjacent to a second end portion of the circuit board, and a casing configured to accommodate the ink writing section, the connection member, the circuit board and the pen pressure detector such that a tip portion of the core body protrudes from the casing.
