プは秀れている。2. Description of the Related Art For example, in a portable telephone as a typical example of portable electronic equipment, a flip type in which a flip is openably and closably attached to a telephone body, and a type without a flip are provided. Is known. The non-flip type is superior in terms of weight saving and convenience, but the flip type is superior in terms of preventing malfunction of switches, compactness, and variety of designs.

構造が要求される。By the way, the hinge device for pivotally attaching the flip to the telephone body maintains the closed state of the flip with respect to the telephone body when not in use, and maintains the opened state of the flip with respect to the telephone body when used. Structure is required.

わしいなど、未だユーザーが満足できるものが提案され
ていないのが現状である。Therefore, in the past, for example, a flip is always urged toward the main body of the telephone in a direction to open the flip, and when the flip is closed, the flip is locked to maintain the closed state. The object or the flip is biased in the closing direction in the rotation range in which the flip is rotated in the opening direction by a predetermined amount from the closed state, while the flip is rotated in the closing direction by the predetermined amount from the maximum opened state. A type configured to urge in the opening direction in the moving range has also been proposed, but since the former cannot use a large urging body due to the nature of the article, it gradually increases in the opening direction. Since the urging force becomes weak, it is difficult to maintain a strong urging force in the maximum open state (actually, the flip may flicker in the maximum open state.) The rotation range does not work (so-called dead angle)
However, in the current situation, there is no proposal to satisfy the user, because it is troublesome because the flip needs to be opened and rotated by hand.
