Battery detecting device for a radio pager. |
摘要 |
<p>In a device applicable to a pager or similar electronic apparatus for detecting a thin disk-like primary battery which feeds power to a load circuit, a secondary battery is provided which is complementary to the primary battery. A receiving portion receives the primary battery and has a first contact terminal for contacting the positive electrode side of the battery, a second contact terminal for contacting the negative electrode side of the battery at one end and connected to ground at the other end, and a third contact terminal contacting the negative electrode side of the battery at one end. When the primary battery is inserted in the receiving portion in a predetermined orientation, a detecting unit determines that the battery is present on the basis of the contact of the second and third contact terminals via the negative electrode side of the battery. <IMAGE></p> |
