A thin plate-shaped annular partition wall 9 is integrally provided in the same direction as and parallel to the partition wall 7. Further, an annular partition wall 11 is provided on the reel 3 by being inserted therein, and a locking claw 12 provided on an outer peripheral edge thereof is detachably connected to a locking claw 13 provided on the other side edge of the cylindrical wall 8. It is stopped and arranged at a predetermined interval from the partition wall 7. A thin plate-shaped member extending in the same direction on the outer peripheral edge of the partition wall 11 serves as a guide for a drawer code 15a of the mouse code 15 described later together with the partition wall 9 and serves to separate the drawer code 15a and the non-drawer code 15b. An annular partition wall 16 is provided integrally. One side separated in the axial direction by the partition wall 16 and the partition wall 11, that is, the outer peripheral surface of the cylindrical wall 8 is on the first take-up portion 17 for winding the drawer cord 15a, and the outer peripheral surface of the reel 3 on the other side. Winds up the non-withdrawal cord 15b
It is formed on the winding section 18.

As described above, reference numeral 15 denotes a four-core type mouse cord, which is a withdrawal cord 15a wound around the first winding section 17 of the reel 3 and a non-drawing cord 15b wound around the second winding section 18.
It consists of As shown in FIGS. 5 and 7A, the drawer cord 15a has a substantially circular cross-sectional shape formed by twisting a four-core cord into a cabtire cable. It is wound in the direction opposite to the biasing direction, and the outer end side where the connector 21 is provided is taken out from the cord outlet 22 provided on the outer peripheral portion of the case 1. The drawer cord 15a wound around the first winding portion 17 is wound over a plurality of stages in both the axial direction and the radial direction. On the other hand, as shown in FIGS.
The core has a flat cross-sectional shape in which the cores are connected in series, and is wound around the second winding portion 18 in the same direction as the pull-out cord 15a. At the inner end of the non-drawer cord 15b (the end opposite to the drawer cord 15a), a mouse body to be described later
A Molex 23 connected to the mouse operation board in 40 is provided. The winding direction of the non-withdrawal cord 15b may be reversed. The non-pull-out cord 15b is locked by a non-pull-out cord outlet 24 provided on the outer peripheral portion of the case 1, and is taken out to the outside. The non-pull-out cord 15b wound around the second winding portion 18 is wound in one stage in both the axial direction and the radial direction.

As shown in FIGS. 5 and 6, both inner ends of the drawer cord 15a and the non-drawer cord 15b are connected by insert molding after soldering the respective wires,
The connecting portion is formed in a thin plate-like square shape. And
The rectangular connecting portion 26 is detachably attached to an attachment recess 27 provided in the partition wall 7 of the reel 3. That is, as is apparent from FIG. 1, the inner end near the connecting portion 26 of the drawer cord 15a wound around the first winding portion 17 was guided to the partition wall 7 from the opening 28 provided in the cylindrical wall 8. In addition, while being meanderingly locked and locked by a locking portion 29 provided on the partition wall, an inner end near the connecting portion 26 of the non-pull-out cord 15b wound around the second winding portion 18 is fixed. Is the reel 3 of the partition 11
After being guided to the partition wall 7 through an opening (not shown) provided near the fitting into the partition wall, it is locked and fixed to a locking portion 30 similarly provided on the partition wall. In this embodiment, both codes 15
The inner ends of a and 15b were formed by insert molding after directly connecting the respective wires by soldering. However, this is only a preferable example, and other inner ends may be connected by connecting metal fittings. It goes without saying that it is good.

As shown in FIGS. 7 (A) and 7 (B), the thickness of the non-pull-out cord 15b in the winding direction of the reel 3 around the second winding portion 18 is the thickness (diameter) of the pull-out cord 15a. Then, in this example, it is as thin as D / 3. As shown in FIG. 5, the length L2 of the non-withdrawal cord 15b is equal to the length L1 of the withdrawal cord 15a. The non-withdrawal code 15b is connected to the reel 3 as shown in FIG.
Is completely wound around the first take-up section 17, the diameter is reduced to a minimum by the second take-up section 18.

As shown in FIGS. 1, 3, and 4, reference numeral 31 denotes a stopper mechanism as a reel stopping mechanism. A stopper claw 32 is pivotally supported at its intermediate portion by a shaft 33 provided on the case 1 so as to be swingable. The reel 3 is always attached and the claw 34 at the tip is always
Is biased by a spring 36 so as to be locked to a locking portion 35 provided on the partition wall 9. An operation portion 37 is provided on the opposite side of the claw portion 34 of the stopper claw 32, and this operation portion swings the stopper claw 32 against the spring 36 to release the engagement with the engagement portion 35. However, when the code reel Y is installed in the mouse main body 40, it is positioned so as to slightly protrude from the operation window 41 formed on the side wall thereof. As shown in FIG. 1, the outer end of the cord reel Y provided in the mouse main body 40 with the connector of the lead cord 15a is taken out of the mouse main body 40 through the cord outlet 43. Note that the mouse body 40 is composed of a lower frame and an upper frame, and that the mouse-shaped body 40 can be assembled by connecting the lower frame and the upper frame. Is connected to a mouse operation board (not shown) as in the prior art, and a detailed description thereof will be omitted.

The operation of this embodiment will be described. First,
Assembling (installation) of the cord reel Y into the mouse body 40
However, the drawer cord 15a slightly pulled out from the code reel Y projects out of the cord outlet 43 of the mouse body 40, and the Molex in the non-drawer cord 15b
After confirming that 23 is connected to the mouse operation board in the mouse body 40, assemble it. This assembling is preferably performed by a one-touch attachment / detachment method using the uneven portion of the resin, but is not necessarily limited to this. FIG. 1 shows this assembled state. In this state, the operation portion 37 of the stopper claw 32 projects from the operation window 41. When the mouse cord 15 is used, when the drawer cord 15a is completely wound around the first winding portion 17 of the reel 3 in the case 1, the connector 21 is pulled out of the case 1 in order to connect the connector 21 to the personal computer body. The reel 3 is rotated against the bias of the spring 6, and the withdrawal cord 15a wound on the first winding portion 17 is gradually withdrawn. With the withdrawal of the withdrawal cord 15a, the non-withdrawal cord 15b wound around the second winding portion 18 of the reel 3 gradually expands from the reduced diameter state, and when the withdrawal cord 15a is completely withdrawn. , Is in the state of being expanded to the maximum. After the drawer cord 15a is completely drawn out, when the drawer is stopped (the same is true when the drawer cord 15a is stopped halfway through the predetermined length), the reel 3 rotates in the reverse direction by the bias of the spring 6. However, this rotation is stopped when the claw portion 34 of the stopper claw 32 of the stopper mechanism 31 is locked by the locking portion 35 provided on the partition wall 9 of the reel 3.

On the other hand, the withdrawal cord pulled out as described above
In order to rewind the first winding portion 15a around the first winding portion 17 of the reel 3, the operating portion 37 of the stopper mechanism 31 is pushed against the spring 36,
The locking between the claw portion 34 of the stopper claw 32 and the locking portion 35 is released.
Thereby, the reel 3 is rotated by the bias of the spring 6,
The cord 15a is wound on the first winding unit 17 of the reel 3 in a state before being pulled out. The non-pull-out cord 15b, which has been in the maximum expanded state at the second winding portion 18 of the reel 3, is gradually reduced in diameter, and when the cord 15a is completely wound, the diameter is reduced again to the original minimum. State. In this case as well, if the pressing of the operation unit 37 is stopped halfway, the withdrawal code 15
The winding of a and the diameter reduction operation of the non-pull-out cord 15b are stopped.

As is apparent from the above description, since the length of the drawer cord 15a protruding outside the mouse body 40 can be adjusted, it is necessary to perform a cumbersome operation such as bundling an unnecessary part of the mouse cord as in the related art. And these operations can be eliminated as much as possible. In addition, the drawer cord and non-drawer cord are contactless, and without using any special fittings,
Since they are directly connected, assembling of each component is easier than that of the contact type, and the cost can be reduced. Further, the drawer cord 15a can be wound in a plurality of stages in both the axial direction and the radial direction, so that the cord thickness associated with the multi-core and a predetermined cord length can be secured, and the non-drawer cord 15b can be wound in the axial direction. 1 in both radial and radial directions
It is possible to make the configuration of that part compact by winding only on the step. In this embodiment, four cores are shown as an example of multi-cores, but it goes without saying that two or three cores or five or more cores may be used. Further, in the embodiment, the example in which the Molex 23 provided at the inner end of the non-withdrawal cord 15b is connected to the mouse operation board is not necessarily required. A connected portion other than the substrate may be used.

[0016]

According to the first to fifth aspects of the present invention, the length of the cord protruding from the outside of the mouse body, which cannot be achieved by the conventional one, can be adjusted, and unnecessary parts of the cord can be eliminated. It can be eliminated as much as possible. In addition, since the structure of the contact part of the cord reel that controls the length of the cord is a non-contact type, it is possible to assemble each component very easily compared to the contact type and to use expensive contact points. Since there is no need to dispose, there is an excellent effect that the cost can be significantly reduced.
