Description

[Detailed Description of the Invention] A. Field of Industrial Application The present invention relates to a cable pulling device for a keyboard.

B. Overview of the invention The present invention is a keyboard cable pull-out device in which an annular cable storage groove is formed on the back surface of the keyboard housing, and a plurality of cables are drawn from the cable storage groove toward the edge of the housing and in different pull-out directions. By forming a cable pull-out groove, the cable pull-out length and pull-out direction can be changed as desired, and excess cables can be stored in the annular storage groove, eliminating the inconvenience of unnecessarily sagging cords. .

C. PRIOR TECHNOLOGY In various electronic devices, keyboards connected to the main body of the device are used. For convenience, cables drawn out from the keyboard have conventionally been treated as shown in FIG. 7A or B. There is.
Each figure is a plan view of the keyboard 1 equipped with a large number of keys 5, 2 is a cable, and 3 is a connector at the tip of the cable. In the case of FIG. 7A, the cable 2 is pulled out from the cable pull-out hole 4 formed on the right side of the tip on the back side of the housing 1a of the keyboard 1, and the cable 2 is pulled out from the cable pull-out hole 4 formed on the right side of the tip on the back side of the housing 1. A cable pull-out groove 6 is directed toward the cable.

In the case of Fig. 7B, the cable 2 is connected to the housing 1a.
The cable is pulled out from a cable pull-out hole 4 formed on the back surface of the cable and at approximately the middle position when viewed from both ends. Cable pull-out grooves are formed in the forward and left-right directions with this cable pull-out hole 4 as a starting point.

D. Problems to be solved by the invention Figure 7A Regarding the cable pull-out means, there are cases where the cable 2 is pulled out immediately forward from the cable outlet 4, and when it is pulled out from the cable pull-out groove 6 to the right end of the housing 1a. The lengths l ₁ and l ₂ of the cable are different depending on when the cable is pulled out, and this causes the problem that the length of the cable cannot be freely selected. I had the inconvenience of not being able to withdraw the money.

In the case of the cable pulling means shown in FIG. 7B, the cable 2 can be pulled out from the left and right sides.
In that case, the length of the cable 2 drawn out is as short as _l2 .
Therefore, when it is desired to extend the cable 2 to a length _l1 , the cable 2 has to be pulled out directly forward from the cable pull-out hole 4, which is a problem. In this way, in the past, it was not possible to arbitrarily pull out the cable of the required length for the keyboard from the required position.
The drawback was that it was difficult to adapt to the layout of the device to which the keyboard was connected.

The present invention has been proposed to improve the above-mentioned drawbacks.

E. Means for Solving the Problems The cable pull-out device according to the present invention has an annular cable storage groove formed on the back surface of the keyboard housing, and a cable pull-out device that extends from the annular cable storage groove toward the edge of the housing and in the pull-out direction. It is characterized by forming a plurality of cable pull-out grooves.

F Function The cable pulled out from inside the keyboard housing is once wrapped around the annular cable storage groove once or multiple times, and then pulled out from any one of the multiple cable pull-out grooves depending on the direction and length of the cable. It is something.

G. Embodiment The present invention will be explained below based on the embodiment shown in FIGS. 1 to 6. It should be noted that the same parts as in the prior art will be described with the same reference numerals.

Figures 1 to 3 show the first embodiment, and Figure 1A
is a plan view, B is a back view, and C is a side view. Further, FIGS. 2A to 2B are explanatory diagrams showing four ways of pulling out the cable 2 from the keyboard housing 1a. In FIG. 1B, 7 is an annular cable storage groove formed on the back surface of the housing 1a, and a plurality of cable pull-out grooves 8 are provided from the cable storage groove 7 toward the front edge of the housing 1a and in different pull-out directions. It is being Each of the cable storage grooves 7 and the cable pull-out grooves 8 are connected to the housing 1.
The outer surface side of the back surface of a is formed to be open. The cable storage groove 7 may be a simple concave groove as shown in FIG. 3A, or it may be provided with small protrusions 7a on both sides of the opening to make it difficult for the cable 2 to slip out of the groove, as shown in FIG. 3B. . Incidentally, the cable storage groove 7 and the cable pull-out groove 8 can be integrally molded when the keyboard housing is molded from plastic. Further, as shown in FIG. 1B, the cable pull-out hole 4 is formed at the tip of the back surface of the keyboard and at a position midway in the left-right direction. Reference numeral 1b is a raised portion that tilts and supports the front end of the keyboard 1, and a cable storage groove 7 and a cable pull-out groove 8 are formed in this raised portion 1b.

Next, with reference to Figure 2 A to D,
The following describes the withdrawal mode.

First, Fig. 2 A and B show the length of the cable 2 from the pull-out groove 8 on the left and right sides of the housing 1a, respectively.
An example is shown in which only l ₁ is pulled out. In this case, the cable 2 pulled out from the pull-out hole 4 passes through the central cable pull-out groove 8 and a part of the cable storage groove 7, is guided to the left and right pull-out grooves 8, 8, respectively, and is directed to the front of the keyboard 1. It's being pulled out. As can be seen in the figure, the left or right pullout groove 8 or 8
No matter where the cable 2 is pulled out, the length l ₁ of the cable 2 is the same.

FIGS. 2C and 2D show an example in which the cable 2 is pulled out by a length l ₂ from the left and right pull-out grooves 8, 8, respectively. In this case, the cable 2 pulled out from the pull-out hole 4 passes through the central cable pull-out groove 8, is guided counterclockwise or clockwise along the cable storage groove 7, and then is guided from the left and right pull-out grooves 8, 8. It is pulled out in front of the keyboard 1. As can be seen from the figure, the length _l 2 of the cable 2 is the same whether the cable 2 is pulled out from the left or right pull-out groove 8 or 8.
