Kind Code:
A1
Abstract:
A capsule-shaped medication device 10 comprises: a capsule-shaped housing 1; a substrate 2 disposed in the interior of the housing 1; a power receiving coil 3 disposed on the substrate; and a secondary battery 4 that can be charged with power received by the power receiving coil 3. The center of gravity 11 of the capsule-shaped medication device 10 is at a position: differing from the center 12 of a cross-section 13 produced by cutting the capsule-shaped medication device 10 in a plane in which the center of gravity 11 passes through a position and which is orthogonal to a longitudinal direction of the capsule-shaped medication device 10; and overlapping with the substrate 2 when viewed in a direction orthogonal to the substrate 2. This charging system for a capsule-shaped medication device comprises: an accommodation sheet that has a plurality of accommodation sections and a metal cover that covers opening sections of the plurality of accommodation sections; capsule-shaped medication devices 10 that are accommodated in the accommodation sections; and a charger which has a power transmission coil and on which is placed the accommodation sheet in which the capsule-shaped medication devices 10 are accommodated.
