Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mouse wiping sheet for preventing contamination of a mouse moving amount detection unit as an information input device.

[0002]

2. Description of the Related Art As is well known, in a mouse which is an information input device for detecting an amount of movement by rolling a ball, articles and means for maintaining accurate input and smooth operation are provided.
There is a mouse pad and means for preventing intrusion of dirt and dirt. The technical challenge to reliably convey the mouse movement is
This is the stabilization of the transmission torque from the ball rolling surface to the ball and the detection roller. Specifically, it is a technique for preventing the slippage caused by a decrease in the transmission torque due to the slippage between the respective members and the stoppage caused by the increase in the transmission torque due to the intrusion of dirt or dirt between the respective members.

[0003] The mouse pad is a rug for the purpose of maintaining a smooth surface, preventing slippage, and preventing wear of the operation surface. A mouse pad comprising various materials such as fibers and a rolling surface on the surface is provided. A mouse pad that newly focuses on a slight oil film to increase the reliability and imparts a cleaning function to the surface function with ultra-fine fibers to prevent contamination of a mouse ball is disclosed in
152936, which is proposed in Japanese Utility Model Application No. 08-3625. In this practical use, the wiping effect of the oil film achieves stability that is distinct from other fibrous mouse pads.

[0004] As means attached to the mouse to prevent the transmission torque from increasing due to invasion of dirt or dirt, there are a sliding surface (a function of preventing the entire bottom surface of the mouse from contacting the operation surface and a function of fixing a low friction material to make it easy to slide. There is a mouse in which a protruding portion is arranged in a ring around the ball. Also, Japanese Patent Application Laid-Open No. 08-6718 proposes that a ring-shaped sealing member is provided around a ball on a cover plate for detaching and attaching the ball by utilizing the sealing property of the fiber for the member. These are sealed off from the outside by a seal to prevent dust and dirt from entering the inside.

[0005]

In order to provide a comfortable input environment, there is a problem in using the mouse pad itself. The mouse pad occupies the desk and gets in the way when the task performed by the computer and the task performed by the conventional writing instrument are mixed. In addition, the position of the mouse pad is fixed and the operation of the mouse pad is limited. For these reasons, it is more comfortable not to use a mouse pad unless there is dirt, dust, or dirt. As a problem from the use environment, in an unspecified number of uses, use is not preferred due to discomfort or theft of dirt. In addition, it is burdensome to carry with a portable device.

[0006] If the mouse pad is not used, problems other than the input failure occur. It is abrasion of the operation surface.
Dust and oily dirt accumulate on the sliding surface of the mouse,
Since a hard sliding surface suppresses the abrasive dirt and rubs the operation surface, a strong abrasive action is generated. This wear occurs as long as the sliding surface and dirt are present.

Next, there is a problem of an oil film existing in the input environment. The adhering fat component accumulates even fine dust that does not originally cause a problem, and becomes accumulated dirt which affects the transmission torque. On the ball surface, a thin oxidized cured film of the attached oil reduces the friction. Then, a reduction in the transmission torque of the ball is caused by a synergistic effect with the slip of the uncured oil or fat. The prevention of the formation of the oxidation cured film cannot be realized unless the invisible oil film is removed. Although this oil film does not have a direct input disturbance feeling, it is an important issue for maintaining comfortable input operation. In particular, in an environment where a mouse pad is not used, the oil film removal technology is a technology for stabilizing the transmission torque.

Next, since the cleaning structure having the sealing function does not have a function of wiping oil film dirt, the oil film dirt cannot be removed.
As proposed with a mouse pad made of a microfiber thread, blocking by a seal or a material mainly composed of general fibers had no effect, and a reduction in transmission torque due to slippage caused by a fat component could not be prevented. For this reason, it has been difficult to maintain a stable input for a long time.

In addition, the movement of the hand in the input operation does not always involve continuous sliding of the mouse, but involves an operation of lifting and adjusting and moving. When this is lifted, it may land on an uncleaned surface. If the cleaning unit is configured based on the shape and members related to the ball, the area that has been cleaned will be narrower,
The probability of dust and dirt entering the interior increases. It is effective for the cleaning unit to effectively use the bottom of the mouse and expand the cleaned area as much as possible.

An object of the present invention is to develop a product for preventing a stain on a moving amount detection unit of a mouse with the object of maintaining stable and accurate input and realizing a comfortable operation environment in a working environment not using a mouse pad. Also consider the versatility that can be applied to existing mice.

[0011]

In the input operation of the mouse, the source of fats and oils is mainly fats and oils coming out of the palm of the user's hand. The fat adheres to the rolling surface, which is the operation surface of the mouse, and adheres to the ball via the rolling surface. The measure of the present invention is not to prevent adhesion of dirt or oils and fats to the ball, but to prevention of adhesion of the surface on which the ball rolls. As this prevention means, the operation at the time of operating the mouse is used for the wiping operation of the operation surface,
Clean the oil film on the raceway. By providing a cleaning function on the bottom surface of the mouse, the surface on which the mouse moves and the surface on which the mouse may move have a clean environment without an oil film due to the wiping effect of the input operation. The ball can roll on a surface free of an oil film or a foreign substance that constantly makes the transmission torque unstable.

This cleaning ability requires an ability to remove even an oil film. As a cleaning technique for removing an oil film in a dry process, wiping with ultra-fine and ultra-fine fibers is known.
The present invention provides a sheet having, as a wiping surface, an ultrafine fiber layer of a woven or knitted fabric or a nonwoven fabric which is mainly composed of 0.0001 to 1 denier ultrafine fiber yarn and has no self-flagging property, and has a pressure-sensitive adhesive layer on the back surface. It is. The sheet is adhered and fixed with an entire or partial adhesive layer to provide an oil film wiping function on the bottom of the mouse.

The fluff of the fiber at the beginning of use and during use, the fiber itself can be a foreign substance. For this reason, it is made of a cloth having no fluffiness, and prevention of fluffiness is taken.

The bottom surface of the mouse is convex and concave with a protrusion on the sliding surface and a concave portion on the nameplate. The surface that occupies the bottom most is the base of the bottom,
The wiping sheet for a mouse is formed by setting the thickness of the sheet to be equal to or less than the maximum ball protrusion size that can be detected from the bottom of the mouse. The sliding surface protrudes in commercially available mice.
If the sheet is too thin, it slides on the sliding surface and the wiping function does not work. Avoid contact with the sliding surface by making it larger than the projecting dimension of the sliding surface. At the same time, grinding of the operating surface on the sliding surface can be avoided. In a commercially available mouse, the thickness of the wiping sheet is 0.
Versatility can be ensured at about 7 to 1.2 mm.

The method of using the mouse wiping sheet is as follows. The mouse wiping sheet is fixed on the bottom surface of the mouse with an adhesive layer so as to surround the protruding portion of the ball. The plane has a flatness consisting of the bottom surface contact surface and the contact operation surface of the ball in a state where the movement amount can be detected. By disposing the arrangement as far as possible from the ball protrusion, a clean area without an oil film can be widely secured. Also, since the function of the sliding surface is lost, releasing the mouse increases the stability of the mouse. Generally, the sliding surface is set to have a small sliding area. Therefore, it is better not to use this surface as a cleaning surface. The arrangement of the bottom surface with a sliding surface is fixed to the surface omitting the sliding surface and surrounds the ball projection.

The form of the sheet is a tape having a width of 5 to 15 mm. It can be arranged by freely cutting and pasting.
This mode corresponds to versatility applicable to existing mice, and is not limited. No sliding surface is required in a mouse structure that employs the means of the present invention to be manufactured in the future. The form applied to this is optimally one cut sheet adhered to the entire bottom surface excluding at least the ball protrusion. The mouse housings are various, and the sheet form is also various.

[0017]

The operation of the present invention will be described. FIG. 1 is a sectional view of the wiping sheet. FIG. 2 is an external view of a bottom view in which the wiping sheet of FIG. 1 is disposed on the bottom surface of a mouse housing. FIG. 3 is a cross-sectional view of a bottom surface portion on which the wiping sheet of FIG. 1 is provided.

The surface of the adhesive layer 2 of the wiping sheet of the present invention is attached to a surface of the mouse housing 3 from which the sliding surface 3a is omitted. The seat is arranged as far as possible from the protrusion of the ball 4. As shown in FIG. 2, the microfiber layer 1 is exposed on the bottom surface of the mouse housing 3.

Next, in the mouse provided above, the ball 4 can be rolled on the operation surface 6 as shown in FIG. 3, and the microfiber layer 1 is in close contact with the operation surface 6. Sliding surface 3
“a” is a state of being floated from the operation surface 6 with the thickness of the sheet. The surface layer of the ultrafine fiber layer 1 exists between the maximum protruding spherical surface on which the movement amount of the ball 4 can be detected and the sliding surface 3a. This surface is preferably set close to the sliding surface 3a.

In this state, when the mouse is moved by performing an input operation, the mouse slides on the surface of the ultrafine fiber layer 1. This movement results in a relationship in which the operation surface 6 is wiped with ultrafine fibers, and a wiping action occurs. The oil film attached to the operation surface 6 is removed by the oil film removing action of the ultrafine fibers. In the initial stage of use, there is an oil film and dirt in the area surrounded by each sheet, but a clean environment is obtained in which the oil film in the area is gradually removed by reciprocating sliding.

In the early stage when dirt is present, a sliding resistance is generated in which the resistance corresponding to the energy for removing the oil film is added.
Thereafter, when the oil film is removed, the oil film gradually decreases, causing friction between the material of the operation surface 6 and the surface of the ultrafine fiber layer 1, and the operation can be performed with an appropriate sliding resistance. Regarding the abrasion of the operation surface 6, the hard sliding surface 3a, which causes abrasion, cannot contact the operation surface 6, so that neither dirt nor polishing occurs. The sliding surface of the fibers is soft and abrasive particles are embedded between the fibers. Therefore, the polishing property is extremely low. Further, as the fibers become thinner, the pressing of the abrasive particles by the fibers themselves is reduced.

When the hand touches the operation surface 6 during the input operation, the fats and oils of the hand adhere to the operation surface 6. Oil and fat adhering to the ball 4
There is an ultrafine fiber layer 1 between the two, and the oil film is removed when the ball 4 rolls due to the wiping effect of the reciprocating sliding of the input operation. The ball 4 always rolls on a clean operating surface 6 without an oil film. It is possible to maintain and realize a comfortable input operation by setting only the moving range of the mouse to a clean input environment.

If the microfiber layer 1 is contaminated during long-term use, the oil film removing ability is reduced, an oil film is formed on the operation surface 6 and the surface of the ball 4, and slip occurs due to slip. When this happens, peel off and replace with a new one. In particular, if a repeatable adhesive which is resistant to washing is employed, the dirt can be reused by washing.

[0024]

FIG. 1 is a sectional view of a first embodiment of the present invention. The wiping sheet of the present invention is implemented using a commercially available woven or knitted fabric. The ultrafine fiber layer 1 is Goodall (trademark) manufactured by Kanebo Co., Ltd. This is 0.1
It is a cross-knitted fabric composed of denier ultrafine fiber yarn and polyester yarn. It is a woven knitted fabric that is easy to adjust to the surface and efficiently captures oil film and dust-like dirt. A double-sided pressure-sensitive adhesive tape is stuck as a pressure-sensitive adhesive layer 2 on the entire surface of one side of the cloth to form a sheet.
Adhesive tape is acrylic, adhesive strength is 800g / 25m
m (for stainless steel). The ultrafine fiber layer is a surface having a wiping function that appears on the bottom surface of the mouse housing. 12m wide
m to obtain a wiping sheet. In this cutting, the cut portion is heat-sealed by ultra-high temperature cutting to prevent self-fluffiness. The sheet thickness is 0.7 mm.

As a woven or knitted fabric other than the above examples, Zavina (registered trademark) manufactured by Kanebo Co., Ltd. and Toraysee Miracle Clos (trademark) manufactured by Toray Co., Ltd. can also be used. A nonwoven fabric made of long fibers that do not fluff due to sliding can also be used. For example, there is Denkitol (trademark) manufactured by Japan Vilene Co., Ltd. This has a function of removing static electricity and can prevent dust from being adsorbed. As described above, it is easy to adopt a woven or knitted fabric which has been subjected to a composition imparting an antistatic property or an antibacterial property or a mixture and treatment without impairing the oil film removing function. An optimal fiber material having an oil film removing function is selected to obtain a wiping sheet.

An adhesive layer 2 is formed on the bottom surface of the mouse (MS mouse manufactured by Microsoft Corporation) which is a commercially available wiping sheet of the above embodiment, without the sliding surface 3a as shown in FIG.
And the ball 4 was disposed so as to surround the protrusion. The surrounding shape differs each time depending on the design of the mouse housing.

This is a second embodiment of the present invention. This embodiment is a wiping sheet used for a mouse having no sliding surface on the bottom of the mouse. However, commercially available mice do not have this structure. FIG. 4 is an external view of the embodiment. A wiping sheet is obtained by attaching a thin double-sided pressure-sensitive adhesive tape as a pressure-sensitive adhesive layer 2 on one entire surface of the woven or knitted fabric of the first embodiment. The sheet thickness is 0.4 mm thinner than the first embodiment.
It is. The sheet is cut into a mouse bottom shape provided with a lid plate opening 7 omitting the removable lid plate. Since the detachable lid plate is not an essential part, the sheet is not fixed so that it can be detached during internal maintenance.

Even if a sliding surface is present, it can be implemented in a cut shape as in the second embodiment. FIG. 5 is an external view of the embodiment. The thickness of the pressure-sensitive adhesive layer 2 can be made larger than the projecting dimension of the sliding surface, and can be carried out on a sheet provided with the non-pressure-sensitive adhesive portion 8 which is not provided in the pressure-sensitive adhesive layer 2 according to the sliding surface shape portion. Alternatively, a double-sided pressure-sensitive adhesive that is thicker than the projecting dimension of the sliding surface is attached to the bottom surface of the mouse without the sliding surface, and then the cut woven or knitted fabric that becomes the ultrafine fiber layer is fixed.

[0029]

As described above, the present invention has the following effects. (A) Unlike the method of removing dirt attached to the ball,
Not attaching dirt to the ball produces a high dirt prevention effect. And remove dirt and foreign matter up to the oil film,
Maintains stable and accurate input. (B) By using the input operation, a clean operation surface like a new one can always be obtained. And the ball rolls on this surface without being conscious. This eliminates the need for a mouse pad and provides a comfortable operating environment. (C) Since the sliding is performed on the soft microfiber surface without making contact with the hard surface, the operation surface of the sliding surface is prevented from being worn. Also, like a mouse pad with functionality, irregularities, protrusions,
Excessive friction such as burial or wiping rubbing does not damage the elaborate ball surface, making the ball last longer. (D) There is versatility applicable to existing mice. There is no change in the size of the mouse after being attached, so it does not hinder portability. In addition, since the dirt cannot be directly touched or visually observed, there is no discomfort. (E) Dirt prevention can be realized with a small amount of fiber. Thereby, it can be provided at low cost. Further, a reusable configuration is easy, and reduction of waste can be realized.
