Abstract

A mouse having a structure that reduces fatigue when using a mouse for operating a personal computer. The mouse has a substantially semicircular shape when viewed from the side, the entire palm is placed so as to wrap the mouse, and the click operation unit is provided on a substantially vertical surface below the front of the mouse. Unlike the normal slightly lifted state, the middle finger is in a state of falling out of force, so that fatigue can be reduced. In order to support the weight of the hand, it is necessary to correspond to the size of the palm of the individual. Therefore, a fulcrum is provided in front of the bottom of the mouse, a light sensor is provided in the vicinity of the fulcrum, and a leg provided behind the bottom of the mouse. The height of the mouse can be changed by expanding and contracting. [Selection] Figure 4

Description

  The present invention relates to a mouse for operating a personal computer.

  A desktop personal computer is usually operated with a mouse, and the mouse is similar in size and shape. In many cases, this is not only for personal computers, but also for other personal computers, and it is thought that the biggest factor is that it eliminates the sense of incongruity in this situation and does not hinder operability.

  However, PCs are often used for a long time and for a long time, and fatigue of the arms and shoulders is taken away. On the other hand, in Cited Document 1, a mouse is too small for a person with a large hand, and therefore, a form that aims to reduce fatigue by encouraging a stable operation that fits well in the palm by using an auxiliary tool and having a large shape is disclosed. .

  Also, cited document 2 discloses a form in which acupoints are provided at appropriate positions of the mouse and fatigue is reduced by irradiating far infrared rays. Although it is not directly related to fatigue, a grip type mouse that can be used in a narrow range on a desk is described, and it can be said that a click button can be easily added.

  Although not so often seen in mice, many wrist rests, arm rests, wrist belts, magnetic belts, etc., have been devised for wrists and arms.

  Possible causes of fatigue of the shoulder and arm due to long-term use of the mouse are, for example, excessive tension or a fixed posture of the wrist for a long time. The wrist fixed posture is not simply fixed without moving the hand, but the tip of the wrist is positioned above the mouse, that is, the wrist is warped and is in a posture prone to fatigue. Also, in preparation for a click, the index finger and the middle finger are supported in a state of floating above the mouse, and although it is a slight force, the fatigue only increases for a long time.

  Therefore, an object of the present invention is to provide an effective mouse that reduces fatigue when the mouse is used for a long time.

  In order to reduce fatigue of the arm, the posture in which the arms, wrists, and hands are in a natural shape is the most effective, and it can be said that the hand is placed at the operation position of the mouse on the desk. In this state, it is the joint (lunar bone) outside the wrist that puts the most weight on the desk. The inner joint (the scaphoid bone) is in a state where it floats and is not heavy. In other cases, it may be the side of a little finger or thumb, or the tip of a finger. There are also cases where the elbow is attached or the arm is supported at the corner on the near side of the desk, but this is related to the height of the desk and the individual's posture and is not particularly important. Usually, a method is used in which the wrist is fixed with a lunar bone and the mouse is operated while swinging.

  Therefore, the index finger and the middle finger used for the click operation are maintained in this state, and are supported on the mouse in a state where the two fingers are weakened, instead of being supported above the mouse. To do. In other words, the mouse has an upper surface without a click operation unit. The location having the click operation unit is the tip (fingerprint portion) of the weakened index and middle fingers. Of course, it is provided on a substantially vertical surface where the weight of the finger is not applied. This will be described in detail in the form section with reference to the drawings.

  Unlike a state in which a mouse is lifted and held in preparation for a click operation, the mouse of this shape is in a state where the entire arm including the finger is weak and relaxed, and prevents accumulation of fatigue.

  A form is demonstrated in detail with reference to FIGS. First of all, in order to place the hand in a weak state, it is necessary to disperse and support the weight of the hand, support the vicinity of the middle finger base, which is the center of gravity of the hand, and the entire palm is the mouse (1) It can be said that a light touch on the screen is suitable for operability. Therefore, it can be said that a substantially semicircular side view according to FIG. 2 is optimal. The index and middle fingers for the click operation are placed on the mouse (1), the thumb is removed from the desk while supporting the mouse (1) lightly from the side, and the ring finger and little finger are similarly placed on the opposite side of the mouse (1 ).

  The wrist lunar bone is in a state of supporting the weight of the arm or the like on the desk, and the cursor can be easily moved by swinging with the thumb and little finger that gently support the mouse (1) around the lunar bone. can do. In other words, the mouse (1) is sized to be completely wrapped in the palm. Here, the correspondence to the palm size due to individual differences will be described later.

  In the configuration of the click operation unit, the click left button (2), the click right button (3), and the wheel (4) are arranged on a substantially vertical plane below the front surface of the mouse (1) (see FIG. 2). Therefore, the weight of the finger is not affected. Although the arrangement of the operation unit is similar to the conventional one, the click button needs to be recognized by the tactile sensation of the finger, and may be convex as shown in FIG. 1 or may be concave. Further, as in the prior art, the tip portion may be divided into two parts on the right and left, and a click operation may be performed by pressurizing the tip portion.

  Next, instead of placing your hand on the mouse (1), you can further relax, for example, if you just support it lighter than both sides, you can further reduce fatigue and frequently perform click operations and wheel operations. If not, this method is more appropriate. Therefore, the side click button (6a) and the side wheel (6b) are brought into an operable state by an operation changeover switch (5) provided at an appropriate position. The operation unit provided on the side surface and the main operation unit provided on the front surface can be operated at the same time and can be operated alternately, and are not limited to any one. However, this structure cannot be used for right-handed and left-handed people, but is intended for individual use.

  Next, the mouse (1) can be handled by providing a slide leg (7) according to FIG. 6 as a shape corresponding to the size of the palm due to individual differences and fixing it at an arbitrary position. In this state, a tilting fulcrum (8) is provided in front of the bottom surface of the mouse. However, the sensitivity of the bottom optical sensor is lowered slightly from the desk surface (9), and sometimes it is not detected. it is conceivable that. Therefore, by providing an optical sensor in the immediate vicinity of this tilting fulcrum (8), the same operation as usual becomes possible.

  In addition, the necessity of “front” which is the front of the bottom of the mouse is that when the mouse operation is swung, the position is farther from the wrist, that is, the closer to the fingertip, the easier it is to swing. The bottom surface of the mouse in front of the tilt fulcrum (8) is an inclined surface that rises forward. Moreover, the position provided with the slide leg (7) may be the bottom surface or the side surface of the mouse (1), and is not limited to the installation position, the number of installations, the shape, or the like as long as the stability during operation is obtained.
