Abstract
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.
