Abstract

PROBLEM TO BE SOLVED: To suppress sweating from the arm or hand sticking to the palm rest of a personal computer and to reduce keying errors caused by a slip with sweat or uncomfortable feelings caused by key operation on the sticky condition. SOLUTION: In the personal computer having a palm rest part 2, a rugged structure provided with grooves at fixed intervals in the lateral direction to a keyboard is formed on the surface of the palm rest part 2 with which the arm or hand comes into contact at the time of key operation. Thus, the arm or hand in contact with the palm rest part 2 is not turned into sticking state and sweating from the arm or hand can be suppressed by the intervals among the arm, the hand and the palm rest part 2.

TECHNICAL FIELD OF THE INVENTION

[0002]

2. Description of the Related Art Conventionally, a personal computer is usually provided with a keyboard device, and a palm rest portion on which a rear portion of a hand can be placed when an operator inputs a key with both hands on the keyboard. There is.

[0003] The presence of the palm rest allows the key operation to be performed without putting extra force on the hand for key operation, thereby reducing the fatigue of the operator for key input and reducing key input errors. It is effective.

[0004]

In a personal computer having such a palm rest, an arm or a hand for key operation is generally operated on the surface of the palm rest. At this time, although there are differences between individuals, in most cases the arms and hands on the palm rest surface perform key operations without changing the position, so the palm rest that comes in contact with the arms and hands is always in close contact, He was sweating from his arms and hands.

[0005] In addition, the heat generated by a personal computer having a palm rest causes more and more rapid sweating, and there is a problem that key slippage due to slippage due to sweat and uncomfortable key operation due to stickiness.

SUMMARY OF THE INVENTION Accordingly, in order to solve the above-mentioned problems, the present invention suppresses sweating from an arm or hand in close contact with a palm rest of a personal computer having a palm rest portion, and prevents key input errors caused by slippage caused by sweat and solids. Provided is a structure for reducing discomfort such as having to perform a key operation in a connected state.

[0007]

According to the present invention, in order to prevent sweating without changing the position of the arm or hand on the surface of the palm rest when performing key operation, the palm rest surface is provided with irregularities, and the arm or hand is provided. By avoiding the close contact state, sweating is suppressed, and key input errors due to slippage due to sweat and uncomfortable key operations due to stickiness are reduced.

By forming the provided uneven structure 3, the arms and hands in contact with the palm rest 2 do not come into close contact with each other, and the gap between the arms and hands and the palm rest 2 prevents the arms and hands from sweating. It is a structure that can be.

(Embodiment 2) As shown in FIG. 2, in a personal computer 1 having a palm rest portion 2, grooves on the surface of the palm rest portion 2 with which an arm or a hand comes in contact with a key when the keys are operated are arranged at a predetermined interval laterally with respect to the keyboard. By making the tip of the concavo-convex structure provided with a round shape, the area where the arm or hand contacts the palm rest can be further reduced as compared with the first embodiment.

(Embodiment 3) In the personal computer 1 having the palm rest portion 2, the surface of the palm rest portion 2 with which an arm or a hand contacts at the time of a key operation is provided with grooves provided at a predetermined interval in a lateral direction with respect to the keyboard. By providing the structure 3 on the side surface of the palm rest portion 2, even if a key operation is performed while the surface of the palm rest portion 2 is completely covered, air flows from the side surface of the palm rest portion 2. This is a structure that can prevent perspiration and suppress perspiration at the portion that covers the surface of the palm rest portion 2.

(Embodiment 4) In a personal computer 1 having a palm rest portion 2, an uneven structure 3 on the surface of the palm rest portion 2 with which an arm or a hand comes into contact at the time of key operation is used.
By providing linear grooves at regular intervals so as to be at right angles to the direction in which the force of the hand that applies the key operation is applied, it is possible to reduce slippage of the arm or hand during key operation that causes key input errors The structure is as follows.

(Embodiment 5) In the personal computer 1 having the palm rest portion 2, the groove of the embodiment 4 is formed into a curved shape as the uneven structure 3 on the surface of the palm rest portion 2 with which an arm or a hand comes in contact with a key operation. The direction in which the force of the arm or hand performing the key operation is applied and the groove can be easily made perpendicular to each other, and the slip of the arm or the hand at the time of the key operation due to a key input error is further reduced as compared with the fourth embodiment. This is a structure that enables reduction.

(Embodiment 6) In a personal computer 1 having a palm rest portion 2, an uneven structure 3 on the surface of the palm rest portion 2 with which an arm or a hand comes into contact at the time of key operation is used.
By providing the combination of the straight groove of the fourth embodiment and the curved groove of the fifth embodiment, the direction in which the force of the arm or hand for key operation is applied can be more easily made perpendicular to the groove,
Slip of an arm or a hand at the time of key operation due to a key input error can be further reduced as compared with the fifth embodiment.

(Embodiment 7) In the personal computer 1 having the palm rest portion 2, the user can use the palm rest portion 2 having a structure for reducing perspiration by providing the personal computer 1 with an opening / closing door 4 for fixing the palm rest portion 2. Is a structure that can be freely selected.

(Embodiment 8) In the personal computer 1 having the palm rest 2, a rail 5 is provided on the personal computer 1 so that the palm rest 2 can be inserted and removed by sliding the palm rest 2, thereby reducing perspiration. A structure that allows the user to freely select the use of 2.

(Embodiment 9) In the personal computer 1 having the palm rest 2, the blower 6 is provided so that the wind can be artificially blown to the uneven structure 3 of the palm rest 2, which is in contact with the arm or hand during key operation. By providing
This structure allows sweating from the arm or hand contacted during key operation to be further reduced.

(Embodiment 10) In a personal computer 1 having a palm rest portion 2, an air intake device 7 is provided on an uneven structure 3 of the palm rest portion 2 with which an arm or a hand comes into contact at the time of key operation so that an artificial wind can flow. Thus, it is possible to further reduce perspiration from the arm or hand contacted during key operation.

As described above, by adopting the structure as in the first to tenth embodiments, the present invention aims to prevent sweating without changing the positions of the arms and hands on the palm rest surface when performing key operations. By providing irregularities on the palm rest surface so that the arms and hands are not in close contact, sweating can be suppressed, and uncomfortable key operations due to slipping due to sweat and key input mistakes and stickiness can be reduced.

[0020]

As described above, according to the present invention, in order to prevent sweating without changing the positions of the arms and hands on the palm rest surface when performing key operations, the palm rest surface is provided with irregularities, By preventing the arms and hands from being in close contact, sweating can be suppressed, and uncomfortable key operations due to slippage due to sweat and key input errors and stickiness can be reduced.
