PEN INPUT DEVICE COMPRISING BATTERY AND METHOD FOR OPERATING SAME

According to an embodiment of the present disclosure, a pen input device may include a tubular housing that includes a front opening and a rear opening disposed opposite to each other. The pen input device may further include an assembly that is accommodated in the housing and includes a pen input generating means including a pen tip disposed in the front opening and generating a position signal and a pen pressure signal of the pen input device, a battery, a printed circuit board (PCB) disposed between the pen input generating means and the battery and electrically connected to the pen input generating means and the battery, and a support means on which at least a part of the pen input generating means, the battery, and the PCB are disposed. The pen input device may further include at least one conductive member electrically connecting the PCB and the battery, a buffer means disposed in the rear opening, and a polymer filled in an inner space of the housing. The support means may include a support plate extended in a direction toward the rear opening from the front opening of the housing, and may further include a first partition, a second partition, and a third partition which are protruded from the support plate and sequentially spaced in the direction. The pen input generating means may be combined with the first partition, the PCB may be disposed between the first partition and the second partition, and the battery may be disposed between the second partition and the third partition. A stepped structure may be formed on an inner surface of the housing between the third partition and the buffer means to prevent the buffer means from moving toward the third partition. The at least one conductive member may be disposed to penetrate an opening formed in the second partition. Other embodiments are possible.
