< Topic >At the same time thin shape being lightweight, it is possible, to install in the range where the body is wide the healthy monitoring system which uses the active mass meter, and the active mass meter whose management is easy is offered.SolutionsAs the case itself you attach inside the frame and this frame which consist of 40 and electric battery cover 43 you measure the active mass which facilities is done, way from the module 22 which had the communication facility which transmits the active mass data which was measured to the information terminal outside it is constituted, module 22 becomes, as either of one circuit substrate 210 active mass data calculation means and means of communication distribution facilities are done on the aspect of one side, installing electric battery electrode 31 on the other aspect of circuit substrate 210, electric battery cover encloses electric battery 3 interchangeable with electric battery electrodes 31 of 43 and module 22It did. In addition, the concave falling section in order to install the emblem on the surface of case itself 40 was provided.< Choice figure >Drawing 1【課題】薄型且つ軽量で、身体の広い範囲に取り付けることが可能であり、管理が容易な活動量計、及び、活動量計を用いた健康監視システムを提供する。【解決手段】ケース本体40と電池蓋43とからなる筐体と、この筐体の内部に付設する活動量を測定すると共に、測定した活動量データを外部の情報端末に送信する通信機能をもったモジュール22とから構成され、モジュール22は一枚の回路基板210のいずれか一方の面に活動量データ算出手段および通信手段を配設すると共に、回路基板210の他方の面に電池電極31を取付けてなり、電池蓋43とモジュール22の電池電極31との間に電池3を交換可能に収納するようにした。また、ケース本体40の表面にエンブレムを取付けるための凹陥部を設けた。【選択図】図1
