[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mouse pad that is laid between a mouse and an object on which the mouse is arranged when using the mouse as input means to a computer or the like.

[0002]

2. Description of the Related Art In recent years, personal computers (personal computers) use a mouse together with a keyboard as input means for data and the like. The mouse is configured such that, when the mouse is moved, a ball provided at the bottom rotates, and the amount of rotation is transmitted to the personal computer as the amount of movement of the mouse.

When the mouse is used on a desk having a small frictional resistance, the ball may run idle, and the amount of movement of the mouse may not be accurately transmitted to the personal computer. For this reason, when using a mouse, it is common to use a mouse with a mouse pad having a predetermined frictional resistance on its surface spread on a desk.

[0004]

However, when a call is received during operation of the personal computer and the user has to take notes of the call, the keyboard of the personal computer arranged at the center of the desk is an obstacle. Therefore, the keyboard must be moved in order to secure a space for disposing the memo paper, which requires much effort.

When moving the keyboard,
In some cases, keys on the keyboard may be pressed, which may adversely affect personal computer operations.

The present invention has been made in view of such conventional problems, and has as its object to provide a mouse pad which can effectively utilize a limited space.

[0007]

According to a first aspect of the present invention, there is provided a mouse pad in which a writing layer which is erasable by a stationery such as a pencil or an eraser is formed with irregularities. It has a sexual friction surface.

Create an empty space on the mouse pad. At this time, a writable friction surface is formed on the surface of the mouse pad, in which a writing layer erasable by a stationery is formed unevenly, so that a mouse is moved and a pencil is inserted into the empty space formed. The notes are written down with a writing instrument such as a pencil or a mechanical pencil. In addition, since the writable friction surface has the writing layer formed with irregularities, accurate transmission of the amount of movement of the mouse to the personal computer is also ensured.

In the mouse pad according to the second aspect of the present invention, a sticking portion is formed on the back surface of the sheet-like base material so that the base material can be detachably attached to an object, while a stationery such as a pencil or an eraser is formed. A writable friction surface, in which a writable writing layer was formed on the surface of the substrate, was provided on the surface of the substrate.

That is, since the writable friction surface similar to the first aspect is formed on the surface of the base material, the memo function by the writing implement and the accurate movement amount of the mouse to the personal computer are performed as described above. Simultaneous transmission is obtained. In addition, by forming a sticking portion on the back surface of the base material, which allows the base material to be releasably attached to an object, the base material can be formed to be thin, and writing with a writing instrument is improved.

Further, in the mouse pad according to the third aspect, the display unit is provided on the base material to indicate a writing area which can be seen through from the surface.

That is, since the writing area is displayed on the front surface by the display unit, a method of using the memo in the writing area and the memo in another area is used. When the writable friction surface is formed only in a specific area, the display area is formed so as to surround the writable friction surface, whereby the writing area is clarified.

In the mouse pad of the present invention, the writable friction surface is formed by printing an ink containing silica.

[0014] Thus, a writable friction surface, in which a writing layer erasable by a stationery such as a pencil or an eraser, is formed in irregularities, can be easily formed by a printing technique.

In the mouse pad of the present invention, an ink containing silica is printed on the surface of a transparent sheet-like base material and can be erased with a stationery such as a pencil or eraser. While forming a writable friction surface having transparency formed by a rough writing layer formed in irregularities, on the back surface of the base material, a display portion showing a writing region, and forming a background color with a color different from the display portion A colored layer composed of a background portion to be formed was formed by printing, and an adhesive portion for detachably attaching the base material to an object was formed on the colored layer by printing.
