Abstract

PURPOSE:To reduce the space on a desk for installation of a keyboard device when this device is not used by securing the independence of the keyboard device. CONSTITUTION:The plane parts 15 and 16 are provided on the same level at the upper parts of an upper case 2 and a lower case 3 respectively. Then such a positional relation is secured so that the perpendicular line drawn from the centroid G of a keyboard device 20 does not get out of both parts 15 and 16.

Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention is applicable to OA applications such as word processors, personal computers, and workstations.
Pertains to keyboard devices for inputting data to devices, especially:
The present invention relates to a keyboard device that can stand up on its own or stand up against the main body of OA equipment when it is not in use.

0002

2. Description of the Related Art A keyboard device 6 for inputting data into office automation equipment such as a word processor, personal computer, or workstation is designed to reduce the installation space on a desk when the keyboard device 6 is not in use, as shown in FIG.
It has a structure that can be attached to the front of the A device main body 7.

Conventionally, in this mounting structure, a claw 8 is provided at the rear of the keyboard device 6, a corresponding hole 9 is provided in the main body front panel 13, and a hole 1 is provided in the front portion of the keyboard device 6.
0, and a hook 11 is arranged on the front panel 13 of the main body corresponding to this. The keyboard device 6 is fixed by hooking the claws 8 at the rear of the keyboard device 6 into the holes 9 in the front panel 13 of the main body, and hooking the holes 10 at the front of the keyboard device 6 with the claws 11 at the top of the front panel 13 of the main body while rotating the keyboard device 6. Ru.

Furthermore, since it is necessary to release this fixed state, a mechanism 12 for this purpose is provided. These attachment structures and release mechanisms are based on combinations of claws and holes, claws and grooves, etc., but these combinations are not particularly important, and some are realized by combinations that have equivalent functions.

[0005]

[Problems to be Solved by the Invention] In the above-mentioned prior art, it is necessary to provide the main body front panel 13 and the keyboard device 6 with a mounting structure and a release mechanism, which increases the number of parts, increases cost, and makes assembly difficult. There was a problem. The claws 8 and grooves 10 provided on the keyboard device 6, and the holes 9 and claws 11 on the front panel 13 of the main body pose major design constraints. Furthermore, from the point of view of standardization, this poses a particularly large restriction when a keyboard device is shared by multiple models of different designs. Furthermore, the direction in which the main body connection cable is taken out from the keyboard device poses a problem, which sometimes hinders the common use of the keyboard device.

[0006] An object of the present invention is to enable the keyboard device to stand on its own without providing a mechanism for fixing the keyboard device to the main body of the OA equipment, and to reduce the installation space on the desk when the keyboard device is not in use. Our aim is to provide what we can. Furthermore, it is an object of the present invention to provide a keyboard device in which a main body connection cable can be exited from anywhere on the left, right or center.

[0007]

[Means for Solving the Problems] The above object is achieved by providing a flat part in the case of the keyboard device and further providing a storage holding part in the flat part.

[0008]

[Operation] By providing a flat portion at the rear of the case of the keyboard device so that the perpendicular line from the center of gravity of the keyboard device does not extend beyond the flat portion, the keyboard device can be made to stand on its own.

[0009] Furthermore, by providing a groove in the flat part of the case to accommodate the main body connection cable, the cable does not become a hindrance when the keyboard is put up, and the cable can be taken out from either the left or right side of the main body.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

1 to 3 show three views (top view, side view, and rear view) of a keyboard according to the present invention. FIG. 6 is a perspective view showing the keyboard device 20 in use. Figure 7 shows the lower case in the process of being assembled, the main body connection cable,
Shows the relationship between cable holders.

The keyboard unit includes a key switch 1, a keyboard control section, and a main body connection cable 4 connected to the keyboard control section. The keyboard unit is placed on the lower case 3, the main body connecting cable 4 is inserted between the cable fixing pins 22 of the lower case 3, and the main body connecting cable 4 is held by the cable holder 14. Furthermore, cover the upper case 2, fit the fitting part, and fix with screws. The upper part of the upper case 2 and the upper part of the lower case 3 are provided with flat parts. The plane part 15 of the upper case 2 and the plane part 16 of the lower case 3 are on the same plane.

FIG. 8 is a side view showing the keyboard device placed upright in front of the OA equipment main body. The plane parts 15 and 16 are structured so that a perpendicular line from the center of gravity G of the keyboard device 20 does not come out from the plane parts 15 and 16. In addition, these flat parts 15 and 16
It is preferable that the upper part of the keyboard 20 placed upright be inclined slightly toward the OA device main body as shown by the arrow. Further, the planar parts 15 and 16 have storage holding parts 17 made of grooves or the like, and for example, protrusions 18 are provided along the entrances of the grooves 17. When the main body connection cable 4 is fitted into the groove 17, the cable is fixed by the protrusion 18. This makes it possible to take out the cable from the side surface of the keyboard device 20 instead of from the rear of the keyboard device 20, allowing the keyboard device 20 to be erected with the flat parts 15 and 16 facing down without being obstructed by the cable. I can do it.

Furthermore, the groove 17 is arranged so that the keyboard device 2
Since the main body connection cable 4 extending from the center extends to both the left and right ends of the keyboard device, it can be extended to either the left or right by inserting it into the groove 17 of the keyboard device. Thereby, the position of the connector 21 on the main body side is not restricted and the keyboard device can be compatible with a plurality of models, so that the keyboard device can be shared.

FIG. 9 shows a state in which the tilt stand 5 of the keyboard device 20 is raised. The tip of the tilt stand 5 and the flat part 15 of the upper case 2 and lower case 3,
16 is on the same plane. This can serve as a stopper to prevent the keyboard device 20 from falling toward the lower case side.

[0016]

According to the present invention, in a keyboard device consisting of a key switch, a keyboard control section or a keyboard control board, a main body connection cable, and a case, when the keyboard device is not used, it can stand alone. The installation space on the desk can be reduced. That is, it is possible to achieve a reduction of approximately 80% or more with respect to the installation space when the keyboard is in use.

Furthermore, since the main body connection cable can be extended to either the left or right side of the keyboard device, there is no restriction on the connector position on the main body side, and it is possible to support multiple models, making it possible to share the keyboard device. can be achieved.
