The pen body 1 houses a control device consisting of a battery pack, a PCB, and a chip, which controls the various functions of the pen. A power receiving unit 2 is provided on the sidewall of the pen body 1. This unit is electrically connected to the battery pack in the control device. A removable charging device 3 is attached to the power receiving unit 2 and connected to an external power source to provide power to the power receiving unit 2 and transmit the power to the control device.

The charging housing 34 is hollow and, when joined to the charging mounting plate 33, forms a cavity for accommodating the adsorber 31 and charging connector 32. Both the adsorber 31 and charging connector 32 are fixed to the charging mounting plate 33. Furthermore, a through-hole 35 is provided on one side of the charging housing 34 for passage of a wiring harness 37 connected to an external power source. A clip 36 is provided on the charging mounting plate 33 corresponding to the through-hole 35, which is used to secure the wiring harness 37.
