- the shaft portion 554 holds the second straight groove portion 565 (:, the vertical movement groove portion 566C, and the In this process, the blade body 553 of the movable cutter 55 moves from the top dead center to the first bottom dead center, and the blade body 553 is pulled out from the sensor pack 1C.
- the state is the same as that shown in.
- the used sensor pack 1C is discarded in a state where the no sensor 1C is re-stored. Therefore, since the biosensor 13C can be discarded integrally with the package, the number of items to be discarded is small and sanitary.
- a biosensor 13D shown in FIG. 41 can be used as a biosensor constituting the sensor pack.
- the biosensor 13D is provided on both sides of the partial force biosensor 13D for causing the blade 553D of the moving cutter to interfere when the biosensor 13 is moved. More specifically, in the biosensor 13D, a pair of convex portions 130D and 131D are provided on each of the both side edges, and the blade 553D is positioned between these convex portions 130D and 131D. It is configured so that the 553D can interfere with the convex portions 130D and 131D.
- the protrusion 130D is a portion where the blade 553D interferes when the biosensor 13D is moved in the direction of arrow F, and serves to regulate the relative movement of the biosensor 13D with respect to the sealing sheet base film in the sensor pack. It also functions as a stocker.
- the protrusion 131D is a portion where the blade 553D interferes when the biosensor 13D is moved in the direction of arrow F.
- the present invention is not limited to the first and second embodiments described above, and various design changes can be made.
- the sensor pack and the biosensor may be configured as shown in FIGS.
- the sensor pack 1 shown in FIG. 42 is obtained by laminating the base film 14, the sealing sheet 12b, the biosensor 13, and the sealing sheet 12a in this order.
- the sensor pack shown in FIG. 43A and FIG. 43B is one in which the base film is omitted and the biosensor is accommodated only by the sealing sheets 12a and 12b.
- the biosensor 13 shown in FIG. 44 has the electrodes 134 to 136 exposed in a series.
- the opening mechanism according to the first embodiment can be applied not only to opening the sensor pack in the analyzer but also to other uses.
- the present invention can be applied to opening the package when removing the contents.
- the contents can be taken out by using the same method as in the previous analysis device when the contents are solid 3 ⁇ 4 ⁇ , but regardless of the form of the contents, squeeze the contents with a roller, for example. Can also be performed.
