Abstract

A biological signal measuring equipment used in a measurement of a biological signal in a head portion, has a jaw contact portion that comes into contact with a forehead; an occiput contact portion that comes into contact with an occiput; and a supporter that is interposed in a front and rear direction of the head portion and is supported by the head portion by using the jaw contact portion and the occiput contact portion as ends. The biological signal measuring equipment performs the measurement in the same manner as the case of measuring a wave motion of a short period, even in the case of measuring the wave motion of a long period generated in a head portion.

Claims

1-7. -7. (canceled)

8. A biological signal measuring equipment that is used in the measurement of a biological signal in a head portion, comprising:

a forehead contact portion that comes into contact with a forehead;

an occiput contact portion that comes into contact with an occiput;

a supporter that is interposed from a front and a rear direction of the head portion and is mounted on the head portion by using the forehead contact portion and the occiput contact portion as ends; and

an attachment opening that is provided in the supporter, and attaches an arm extended from the supporter in a freely attachable and detachable manner,

wherein the position of the attachment opening is a position where a distance to an electrode to be attached to a portion situated on a median sagittal plane of the supporter and a distance to an electrode to be disposed in an earlobe and attached to the arm are in a shortest distance relationship.

9. The biological signal measuring equipment of claim 8, further comprising:

a case that is connected to a portion provided with the attachment opening and is protruded to the supporter,

wherein an analog-based electronic circuit is disposed in the portion provided with the attachment opening, and a digital-based electronic circuit is disposed in the case.

10. The biological signal measuring equipment of claim 8, further comprising:

a plurality of amplification portions that are provided in the portion of the supporter provided with the attachment opening or in the vicinity thereof, and correspond to the electrode attached to the supporter and the electrode attached to the arm,

wherein a grounding of the plurality of amplification portions is concentrated in the portion of the supported provided with the attachment opening or in the vicinity thereof.

11. The biological signal measuring equipment of claim 8, further comprising:

a measurement portion that measures a potential difference between the electrode to be attached to the portion situated on the median sagittal plane of the supporter and the electrode to be disposed in the earlobe and attached to the arm, as a biological signal,

wherein the measurement portion compares an average of a level in biological signals for each prescribed period with a threshold value set to the average, and when the average is lower than the threshold value, the measurement portion notifies that the electrodes need to be remounted.

12. The biological signal measuring equipment of claim 8,

wherein the supporter has a supporter portion situated on the median sagittal plane, and a pair of branching portions branched from the supporter portion, and

a first occiput contact portion coming into contact with a neck side slope portion of a right side external occiput ridge is connected to one of the pair of branching portions as a rear end, and a second occiput contact portion coming into contact with a neck side slope portion of a left side external occiput ridge is connected to the other of the pair of branching portions as a rear end.

13. The biological signal measuring equipment of claim 12,

wherein a position, where the pair of branching portions is branched, is a position nearer an occiput side than a position where a center of a head needs to face.
