At this time, the mounting adjustment member is placed at a predetermined position inside the fixing frame 20 (in this embodiment, the forehead portion, the connecting portion 21c (positions of the left and right temporal portions), the apex, and the inner portion of the occipital region). Fifty cushioning members (sponge rubber, etc.) are attached.

Next, as an adjustment step, the person in charge of inspection adjusts the mounting state of the fixing frame 20 and the head 99. As described above, the pressure for pressing the cushioning member (sponge rubber or the like) against the head 99 is adjusted by using the pressing adjusting means. If necessary, replace with a cushioning member of a different size and shape.

Subsequently, as an electrode mounting frame mounting process, the inspector attaches the front split frame 30 and the rear split frame 40 to the fixing frame 20. The order of mounting the front split frame 30 and the rear split frame 40 may be any first. As described above, the front split frame 30 and the rear split frame 40 are attached to the fixing frame 20 by the detachable mechanism (fitting mechanism and screw fixing).

In addition, the person in charge of inspection will carry out the replacement process if necessary. That is, when the front split frame 30 and the rear split frame 40 are attached to the fixing frame 20, if it is necessary to adjust the state of attachment to the head 99, or if the attached electroencephalogram electrode unit 80 is adjusted or replaced. When necessary, the person in charge of inspection removes the pre-division frame 30 or the post-division frame 40, which is the target of adjustment or the like. Subsequently, the person in charge of inspection replaces the pre-divided frame 30 or the post-divided frame 40, or replaces the electroencephalogram electrode unit 80 attached to the pre-divided frame 30 or the post-divided frame 40. After replacement, it is reattached to the fixing frame 20.

Here, if the position of the electroencephalogram electrode unit 80 is adjusted or replaced while the electroencephalogram electrode unit 80 is attached to the head 99, the contact state of the non-target electroencephalogram electrode unit 80 with the scalp is changed, and the adjustment is required again. Sometimes. However, in the present embodiment, the replacement work of the electroencephalogram electrode unit 80 in a state of being removed from the head 99 may adversely affect the mounting state, the measurement state, etc. of the electroencephalogram electrode unit 80, which is not the target of replacement or the like.

Further, in order to widen the adjustment range of the mounting state described above, the front split frame 30 and the rear split frame 40, which are the electrode mounting frames, are provided as a kit B in which a plurality of types having different shapes or structures are prepared. That is, an appropriate front division frame 30 or rear division frame 40 is selected from them and attached to the fixing frame 20. More specifically, in the front split frame 30 and the rear split frame 40, the hard material is different, the degree of curvature is different, the positions of the

electrode mounting portions

39 and 49 are different, and the electrode mounting portion 39. , 49 may or may not be provided. Thereby, the wearing state of the frame 10 and the contact state of the electroencephalogram electrode unit 80 can be optimized. As a kit, a plurality of types of fixing frames 20 having different sizes and the like may be prepared.
