Abstract

PROBLEM TO BE SOLVED: To obtain a mouse which is superior in portability by freely adjusting the length of the cord by arranging an elastic member which accumulates a force when the cord is drawn out of the mouse, and releasing the force accumulated in the elastic member and then automatically winding and storing the cord in the mouse. SOLUTION: In this mouse 10, when the cord 40 is drawn out, a spool 23 rotates and a spring is wound to accumulate a force. At this time, the spool 23 is stopped from rotating when a stopper engages a cut part 23c and then the cord is held as it is without being drawn in a case even when slackened. When a stopper knob 27c is pushed, the stopper is released from engaging the cut 23c and the spool 23 becomes free to rotate and rotates reversely to the drawing-out direction of the cord 40 with the force of the spring, so that the cord 40 is wound around the spool 23 and automatically stored in the case. When the mouse is carried, the cord 40 needs not be bundled and the portability is superior.

By moving the mouse on a plane, the amount and direction of the movement are detected and the mouse is displayed on the screen of the computer. By moving the cursor displayed in the box in conjunction with the movement of the mouse, it is easy to select menus and icons, and to proofread tables and sentences. By moving the mouse by hand, the cursor displayed on the computer screen can be quickly moved to the desired position, and it has the advantages of relatively high accuracy and relatively low price, and has the advantages of computer input. Widely used as a device.

[0003] The connection between the computer and the mouse is established by joining a connector provided at the end of a cord extending from the mouse to a predetermined connector provided on the computer body. There are various lengths of cords that can be extended from the mouse, but in general, it is sufficient to take into account that the computer itself is installed under or beside the work desk and that it does not hinder the operability of the mouse. It is necessary to secure a sufficient length, and it has a length of about 400 to 1500 mm.

[0004]

However, when the mouse is operated, the mouse code often gets caught on something or hinders the operation of the mouse. Also, it is messy and unfavorable to see the long code as it is. Furthermore, in recent years, notebook computers that are easy to carry around have been widely used, and the size of computers has been becoming smaller and thinner. Therefore, it is necessary to consider the portability of the mouse, but in the case of a conventional mouse, it is necessary to wrap a long cord around the body of the mouse or to bundle the cord and fix it with a rubber band to prevent the cord from being scattered. It was inconvenient to carry.

In view of the above, the present invention provides a mouse in which the length of the cord of the mouse can be freely adjusted so that the cord is not in the way of operation and the cord is not cluttered and looks neat. With the goal. It is another object of the present invention to provide a highly portable mouse that does not require a cord to be bundled when being carried.

A mouse with a coil winding mechanism, wherein the cord winding mechanism is provided with an elastic member for storing a force when the cord is pulled out from the mouse, and releases the force stored in the elastic member. By doing so, the code is automatically wound up and stored in the mouse. By pulling out the cord stored in the mouse, the spool of the cord take-up mechanism rotates, and by this rotation, a force is applied to the elastic member attached to the spool and stored. When the cord is loosened, the force applied to the elastic member is released, and the spool rotates in the direction opposite to the direction in which the cord is pulled out, and the cord is wound around the spool. It is automatically stored in the mouse.

According to a second aspect of the present invention, there is provided a mouse with a cord rewinding mechanism according to the first aspect, wherein the cord rewinding mechanism further pulls out the cord from inside the mouse. A stopper mechanism for preventing release of the force stored in the elastic member is provided,
By the function of the stopper mechanism, the cord can be held at a desired length, and by releasing the stopper mechanism, the force stored in the elastic member is released and the cord is automatically wound up. It is stored in a mouse. By pulling out the cord, the force stored in the elastic member prevents the rotation of the spool by the stopper mechanism,
Even if the code is loosened, the code is not drawn into the mouse but is retained. When the stopper mechanism is released, the rotation of the spool becomes free, so that the force stored in the elastic member is released and the spool rotates in the direction opposite to the direction in which the cord is pulled out, and the code is rotated. It is wound up by the spool and automatically stored in the mouse.

According to a third aspect of the present invention, there is provided a mouse with a cord winding mechanism according to the first or second aspect, wherein the elastic member is a spring.

According to a fourth aspect of the present invention, there is provided a mouse with a cord winding mechanism according to any one of the first to third aspects, wherein the cord has a diameter of 1.
It is 5 mm to 2.5 mm. The diameter of a cord used in a conventional mouse is about 3 to 5 mm in diameter, and when the cord is wound up with such a thickness, the cord becomes large in volume. It becomes difficult to store and store. Therefore, the diameter of the cord should be about 3 to about 3 to ensure that it can be stored in the mouse even if the cord is wound up while ensuring a practical length.
For 5 mm, a thin cord with a diameter of 1.5 mm to 2.5 mm is used.

According to a fifth aspect of the present invention, there is provided a mouse with a cord winding mechanism according to the fourth aspect, wherein the cord is provided with a reinforcing member for increasing the strength of the cord.
