不具合があった。To measure the electroencephalogram, for example, 21
A large number of individual EEG electrodes must be attached. At this time, in order to reduce the impedance and potential difference between the skin of the head and the electrodes, it is necessary to ensure contact between them, and conventionally, for example, the surface of the electrode made of a silver plate is coated with a conductive silver paste. They were attached one by one to the skin of the head of the brain wave measurement point with an adhesive-coated tape. Therefore, it takes a few hours to prepare before starting the measurement, and at the time of attaching and detaching the silver plate, the subject is not a little distressed. Then, after removing the silver plate, it was necessary to wash the head to remove the silver paste. Moreover, the silver plate of the electrode has a size of about 1 cm 2 , and even if it is pasted with a paste, impurities are apt to intervene between them,
Therefore, the measurement is likely to be inaccurate, but further, if the skin of the head is keratinized, the impedance or potential difference between the skin of the head and the electrode becomes large, and there is a problem that accurate measurement is difficult. .

まだ開発されていないのが実情である。Therefore, for example, using a brain wave electrode probe made of silver-silver chloride and a brain wave measurement probe containing an electrolytic solution such as potassium chloride,
It has been considered to measure an electroencephalogram by contacting a brain wave measuring point on the head with a tip protruding from the tip of the probe and oozing out the electrolyte. When a certain number of such probes are attached to a probe mounting tool such as a helmet-like cap and the head is covered, a plurality of probes come into contact with the head at the same time, but there are individual differences in the size and shape of the head. Therefore, the position of the EEG measurement point varies depending on the subject. Therefore, it is necessary to adjust the mounting position on the probe mounting tool, but in reality, a probe mounting tool that has a simple structure and can easily adjust the probe mounting position has not been developed.

ト部１の円周長を調節することができる。In FIG. 1, an annular belt portion 1 is composed of two parallel wires, and the ends of the wires are connected by a first connecting tool 4 formed of synthetic resin to form an annular shape. That is, as shown in FIG. 2, one end side 1a of the wire is fixed to the first connector 4, and the other end side 1b is slidably inserted into the first connector 4. Here, since the sliding resistance of the wire is designed to have a predetermined value, the wire does not inadvertently slide and the circumferential length of the annular belt portion 1 does not change. By gripping the side 1b and forcibly sliding it, the circumferential length of the annular belt portion 1 can be adjusted according to the size of the head circumference line of the subject.

る。The three arcuate head covering belt portions 2 are also made of two parallel wires, and both ends of the head covering belt portion 2 are intersected by the annular belt portion 1 and the second connecting tool 5, respectively, and at the intersecting positions, an annular shape is formed. It is connected to the belt unit 1. Therefore, the annular belt portion 1 and the three head covering belt portions 2 form a nightcap-shaped hat. As shown in FIG. 3, the second connector 5 made of synthetic resin has holes formed in the vertical and horizontal directions, and the annular belt portion 1 and the head covering belt portion 2 are formed in these holes. It is slidably inserted. When the wire of the head covering belt portion 2 is forced to slide, the arc length of the head covering belt portion 2 changes. That is, by adjusting the circumferential length of the annular belt portion 1 and adjusting the arc length of the head covering belt portion 2, the size of the hat having a night cap shape can be freely adjusted.
Further, when the second connecting tool 5 is slid along the annular belt portion, the head covering belt portion 2 moves in the direction perpendicular to its axis.

っている。The probe holding piece 3 is a cylindrical body made of synthetic resin, and is attached to the annular belt portion 1 and the head covering belt portion 2. In addition, in FIG. 1, one probe holding piece 3
Although only shown, 21 probe holding pieces 3 are actually attached. On the probe holding piece 3,
As shown in FIG. 4, a hole is bored, and the wire of the annular belt portion 1 or the head covering belt portion 2 is slidably inserted into this hole. Therefore, by forcibly sliding the probe holding piece 3, the probe holding piece 3 can be moved along the annular belt portion 1 or the head covering belt portion 2. Therefore, the second connector 5 is slid along the annular belt portion 1 to move the head covering belt portion 2 in the direction perpendicular to the axis thereof, and the probe holding piece 3 is moved to the annular belt portion 1 or the head covering belt. By moving the probe holding piece 3 along the portion 2, the position of the probe holding piece 3 can be freely adjusted. Also in this case, the probe holding piece 3 is prevented from moving carelessly due to the sliding resistance with the wire.

ップ61から滲出して脳波を測定できる。As shown in FIG. 5, the electroencephalogram measurement probe 6 is screwed to the probe holding piece 3 and has a tip 61 protruding from the tip. For example, an electroencephalogram electrode made of silver-silver chloride and potassium chloride are used. It contains an electrolytic solution and forms a half-cell. Then, when the tip 61 contacts the head, the electrolytic solution exudes from the tip 61, and the brain wave can be measured.

When it is desired to attach the probe 6 also at the intersection of the two, as shown in FIG. 6, holes are formed in the probe holding piece 3 in the vertical direction and the horizontal direction, and the circular belt portion 1 and the head covering belt portion 2 are The wire may be inserted so that the probe holding piece 3 also has the function of the second connector. In addition, the sliding resistance of the wire prevents the probe holding piece 3 and the like from moving carelessly,
For example, the wire may be screwed, sandwiched by a clip-like object, or a magnet may be used to prevent the wire from being inadvertently moved. Furthermore, a string may be used instead of the wire.
