Position pointer with connector that electrically connects first circuitry and second circuitry while first housing and second housing are mated to each other

A position pointer that transmits a first signal that enables a position detection apparatus to detect a position pointed to by a core member of the position pointer on an input surface of the position detection apparatus, the position pointer comprising:

• a first housing and a second housing that are couplable with each other along their axial directions to form a tubular housing;
• wherein the core member, in operation, extends outwardly from an axial end of the first housing along the axial direction to point to the input surface of the position detection apparatus;
• a first circuitry housed in the first housing, wherein the first circuitry, in operation, generates the first signal that enables the position detection apparatus to detect the position of the position pointer on the input surface of the position detection apparatus, the first circuitry includes a resonance circuit, and an electric characteristic of the resonance circuit varies according to pressure applied to the core member;
• and
• a second circuitry housed in the second housing and including an integrated circuit which, in operation, outputs information that is stored in the integrated circuit and identifies the position pointer,
• wherein the resonance circuit of the first circuitry, in operation, receives from the position detection apparatus a synchronizing signal and the first circuitry transmits the first signal that enables the position detection apparatus to detect the position of the position pointer on the input surface of the position detection apparatus based on the synchronizing signal,
• wherein the second circuitry includes a terminal and is electrically connected to a terminal of the first circuitry when the first housing and the second housing are coupled with each other along the axial direction of the tubular housing,
• wherein the second circuitry, in operation, generates the second signal by controlling the resonance circuit, the second signal is different from the first signal that enables the position detection apparatus to detect the position of the position pointer on the input surface of the position detection, the integrated circuit housed in the second housing causes the resonance circuit to transmit the information that is stored in the integrated circuit to the position detection apparatus,
• wherein the second circuitry is controlled by a signal transmitted from the position detection apparatus and received via the resonance circuit,
• wherein the second circuitry housed in the second tubular housing is driven by a power supply circuit which, in operation, generates Direct Current (DC) power using Alternating Current (AC) power supplied by the resonance circuit of the first circuitry housed in the first tubular housing, and
• wherein the integrated circuit included in the second circuit is operable when the first housing and the second housing are coupled with each other and the DC power to drive the integrated circuit housed in the second housing is suppliable from the power supply circuit via the terminal of second circuitry electrically connected to the terminal of the first circuitry.
