Description

[Detailed Description of the Invention] (a) Technical Field of the Invention The present invention relates to a code storage structure for a keyboard device which forms the end of information processing input.

(b) Background of the technology In the keyboard device that has no input terminal, in particular, in order to improve the operability of key input by separating it from the main device, it is necessary to prepare a cord of an appropriate length for connecting to the main device on the switch panel side. By doing so, the degree of freedom in installation can be increased.

The present invention proposes a storage structure for a switch board cord that improves the operability.

(c) Prior Art and Problems Conventionally, when using a keyboard device, in order to improve its operability, the main body of the device and the switch panel are separated and connected using a connecting cord.
However, if the extra length of the cord is too long, for example, a method of constructing a special hook on the main unit side and hooking the cord onto the hook has been adopted. However, the projecting part of the main unit hook abuts against the switch panel, which is inconvenient, and it is also unsightly.

(d) Purpose of the invention The purpose of the invention is to eliminate the above-mentioned drawbacks.
That is, the casing of the switch board should be improved to provide a cord storage area and to allow the cord outlet to be freely changed.

(e) Structure of the invention The above object is to provide a keyboard device having a switch board having a connection cord to the main unit and a top cover covering the surface of the switch board, in which the connection code of the top cover is derived. The connection cord can be stored with a gap in the part that covers the rear side of the switch panel, and there are multiple openings between the openings through which the connection cord can be led out to the outside, and the storage part is blocked from the outside. This can be achieved by a cord storage structure of a keyboard device having a continuous recess extending in the longitudinal direction and having a plurality of protrusions for anchoring the connection cord.

(f) Embodiment of the invention The present invention will be described in detail below with reference to drawings showing an embodiment of the invention.

FIG. 1 is a perspective view of the switch panel assembly, and FIG. 2 is a sectional view taken along the A-A' index line, which constitutes the main part of the switch panel of FIG. 1 for storing the cord.

In the perspective view of Fig. 1, 1 is a key switch or push button switch with a large number of panel input switches arranged, 2 is a top cover of the switch board, 3 is a bottom plate of the switch board, and both the bottom plate 3 and top cover 2 are printed circuit boards inside the switch board. It is also a plastic molded casing that houses a circuit-mounted push button switch 1 assembly, which are fastened and assembled using screws. Further, from one end of the assembled casing, for example, the rear end 5 of the switch panel 4, a cord for connecting the keyboard main body device shown in FIG. 6 is led out.

However, the switch board of the present invention has a housing structure that allows the outlet position of the connection cord 6 to be changed freely in order to increase the degree of freedom in operating the switch board. That is, the cords 7, 8, 9, and 10 shown in dotted lines can be accessed from either the left or right or center position of one side end 5 shown in FIG.
is derived. Several protrusions 11 are protruded from the top cover portion of the lead-out for cord mooring.

Furthermore, at the upper cover side end 5 of the assembled case,
As shown in the sectional view of FIG. 2, there is a preformed one transversely extending recess 12 in which a sunshade-like hanging part is formed that covers the upper half of the recess 12, and a connecting cord 6 is inserted into the recess 12. A space is provided for storing the storage cord and holding the storage cord. Although the example diagram only shows a holding space for a single cord, if necessary, the recess 12 may be designed to accommodate a plurality of cords to store the extra length of a long cord connected to the main unit.

(g) Effect of the Invention With such a cord storage structure for a keyboard device, the excess length of the connection cord between the keyboard device and the main device can be stored without the need for a special hook, and the connection cord can be led out from a desired position according to the cord connection position on the main device, improving the operability of the keyboard device and also improving the appearance.

[Brief explanation of drawings]

FIG. 1 is a perspective view of the switch panel assembly of the present invention, and FIG. 2 is a cross-sectional view of the cord storage portion of the switch panel shown in the previous figure taken along the line A-A'. In the figure, 1 is a key switch, 2 is an up-down cover,
Reference numeral 3 denotes a bottom plate of the switchboard, 4 denotes the switchboard, 5 denotes one side end of 2, 11 denotes a protrusion on one side end 5, and 12 denotes a recess.

Claims (1)

[Scope of Claim for Utility Model Registration] In a keyboard device that has a switch board that includes a connection cord to the main unit and a top cover that covers the surface of the switch board, the connection code of the top cover is derived from the switch board. The connection cord can be stored with a gap in the part that covers the rear side, and there are multiple openings between the openings through which the connection cord can be led to the outside, and the connection can be made by blocking the storage part from the outside. A cord storage structure for a keyboard device having a continuous recess extending in a longitudinal direction and having a plurality of protrusions for mooring a cord.
