The purpose of the present invention is to provide an information management device or the like with which surplus charging of a reception-device battery can be suppressed, in examinations using a capsule endoscope. An information management device (30) is provided with: a battery-remaining-capacity acquisition unit (35) for acquiring a current remaining capacity, i.e. a remaining capacity of a battery a storage unit (33) for storing a required remaining capacity, i.e. a remaining capacity required for the battery to last until examination of planned items is completed a charging-time calculation unit (34c) which, in cases when the current remaining capacity is less than the required remaining capacity, calculates a charging time required for the remaining capacity of the battery to reach the required remaining capacity from the current remaining capacity and a controller (36) which, in cases when the current remaining capacity is at least the required remaining capacity, displays, on a display (30a), that a reception device can be used, and which, in cases when the current remaining capacity is less than the required remaining capacity, displays, on the display (30a), information related to the charging time calculated by the charging-time calculation unit (34c).La présente invention concerne un dispositif de gestion dinformations ou similaire avec lequel lexcédent de charge dune batterie de dispositif de réception peut être supprimé, lors dexamens utilisant un endoscope à capsule. Un dispositif de gestion dinformations (30) est doté : dune unité dacquisition de capacité restante de batterie (35) destinée à acquérir une capacité restante actuelle, cest-à-dire une capacité restante dune batterie dune unité de stockage (33) destinée à stocker une capacité restante requise, cest-à-dire une capacité restante requise pour que la batterie dure jusquà ce que lexamen darticles prévus soit terminé dune unité de calcul de temps de charge (34c) qui, dans les cas où la capac
