The present invention provides an operation state detection device which can suitably detect an operation that an operator performs with respect to a person or an object. Nearly whole of the injector 50 is composed of conductive material. A contact tag 1c is buried across an insulating portion 53a. A conductive lower portion 55a and a conductive upper portion 55b of an injector bag 55 are insulated by an insulating portion 55c interposed therebetween. The side wall of an injector box 56 is composed of an insulating material. A contact tag 1d is supported by a support plate 57 having a conductive front and back surfaces. Furthermore, the contact tag 1d is conducted with a floor via a contact tag 1e. Accordingly, when a nurse attempts to fetch the injector 50, a contact path is formed from the right arm of the nurse, sequentially through the contact tags 1c, 1d, 1e, and the floor, and back to the nurse. Therefore, an operation state of the nurse can be detected by a contact communication device 20 collecting ID of the contact tags 1c, 1d, and 1e. |
