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 tubeincluding openings at both of a tip end and a rear end, a writing refillthat is housed inside the shaft tubeand that includes a writing tip exposed through the opening at the tip end, and an electromagnetic induction refillthat is housed inside the shaft tube, that is exposed through the opening at the rear end, and that is employed in electromagnetic induction-based input.

Multifunction pen

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 input touch pen includes a digitizer refill contained inside a shaft tube and including a contact tip and a stepped tip portion rearward thereof, and a knock member protruding from an opening at a rear end of the shaft tube. The contact tip can protrude and retract through an opening at a tip end of the shaft tube. The stepped tip portion has a larger diameter than the opening at the tip end. A relationship A&#x3e;X&#x3e;Y is satisfied, wherein X represents a knock stroke of the digitizer refill, A a distance from the stepped tip portion to an inner surface at the tip end side when the contact tip is sunken inside the opening, and Y a distance that the contact tip is moved by operation of the knock member from a state of protruding from the opening to a state of being sunken inside the opening.

Input touch pen

A rotational electric machine in which a rotor having different-polarity field magnets arranged alternately in a rotational direction is divided axially into two rotor portions so that the axial position of one of the two rotor portions is changed relative to that of the other in accordance with a direction of torque of the rotor or the phase of synthesized magnetic poles of the field magnets is changed relative to that of magnetic poles of the other rotor portion in accordance with a direction of torque of the rotor, and a vehicle loaded with the rotational electric machine.
