Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable personal computer, a personal digital assistant (Personal Digital Assistant PD), and the like.
A) The present invention relates to a keyboard input device used for a mobile phone or the like, and particularly to a keyboard input device that can be used by being connected to a mobile phone or the like.

[0002]

2. Description of the Related Art In recent years, a keyboard input device is connected to a portable device such as a cellular phone, and code data is transmitted by operating a key of the keyboard input device to operate the portable device or input characters to the portable device. May be performed.

[0003]

In this type of conventional keyboard input device, since the key-on determination is made only immediately after the key is pressed, it is desired to retransmit the same code data a required number of times (for example, five times). In some cases, the same key must be repeatedly pressed a required number of times (for example, five times), so that the key operation is complicated and the usability is poor.

[0004] It is an object of the present invention to provide a keyboard input device which overcomes such disadvantages of the prior art and is easy to use.

[0005]

In order to achieve the above object, the present invention comprises a connector which can be connected to a portable device such as a cellular phone, for example, and connects a keyboard body and the portable device via the connector. In a keyboard input device which can connect and input code data to the portable device by key operation of a keyboard body, when the key is pressed and released for a predetermined time or more, the code data transmitted by the key is transmitted to the key device. It is characterized in that it can be repeatedly retransmitted until the pressing is released.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention is configured as described above. When the same code data is repeatedly transmitted, it is not necessary to repeatedly press the same key as in the prior art. Therefore, the key operation is easy and the usability is good.

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a plan view of a keyboard input device in a state where a mobile phone is set, FIG. 2 is a side view of the keyboard input device, and FIG. 3 is a diagram for explaining a retransmission mode.

The keyboard input device has a large number of input keys 1
And a device holding member 3 that covers the upper surface of the keyboard body 2 by folding. The keyboard body 2 is divided into a first keyboard unit 2a and a second keyboard unit 2b having substantially the same area, and both are foldably connected by a unit hinge 4.

The device holding member 3 is made of, for example, a plate material such as a synthetic resin, and is arranged at a position on the back side as viewed from the operator of the first keyboard unit 2a as shown in FIG. The base of the device holding member 3 is rotatably connected to the keyboard main body 2 together with the connector 5. The connector 5 is further rotatable (eg, about 10 degrees) with respect to the device holding member 3.

The mobile phone 6 is mounted on the device holding member 3 in a vertical position, and a connector (not shown) provided at a lower portion of the mobile phone 6 is inserted into the connector 5 so that the mobile phone 6 can input a keyboard. Connected to the device. At this time, in order to make the upper surface of the mobile phone 6 easy to see, an L-shaped support portion 7 is provided at the tip of the device holding member 3, and the mobile phone 6 is As shown in FIG. Reference numeral 8 in the figure denotes a storage box in which a power supply battery and a printed wiring board are stored.

When not using the keyboard input device,
The second keyboard unit 2b is folded on the first keyboard unit 2a around the unit hinge 4, and then the device holding member 3 is folded on the second keyboard unit 2b. By doing so, the width of the keyboard input device becomes very compact.

As shown in FIG. 1, by operating the input key 1 of the keyboard body 2 with the portable telephone 6 connected to the keyboard body 2, desired code data can be inputted to the portable telephone 6.

According to the present invention, a system is provided in which the continuous pressing and releasing time of the input key is counted, and if it is determined that the input key has been pressed and released for a predetermined time or more, the last transmitted code data is retransmitted. Further, when the input key is depressed, the time required for transmitting the code data is waited (wait)
As t), the system repeatedly sends the same code data until the input key is released (key off).

Although not shown, in order to execute these processes, detecting means for detecting ON / OFF of an input key, counting means for counting a continuous pressing and releasing time of the key,
Comparison means for comparing the set time and the key release time,
A retransmission buffer and control means for sequentially executing the above-described series of processing are provided.

FIG. 3 is a diagram for explaining a retransmission mode according to the embodiment of the present invention. As shown in the figure, when the input key is pressed, the code data is transmitted, and the code data is transferred to the retransmission buffer. The key release time is counted, and if it is determined that the key has been released for a predetermined time (for example, 0.5 seconds), the last transmitted code data (code data transferred to the retransmission buffer described above) Is repeated (five times in this example) until the input key is released (key off), and retransmission is stopped by the key off.

The symbol A in FIG. 3 is a push-release determination time (for example, 0.5 seconds), and B is a retransmission interval time. It is preferable that the release determination time A / the retransmission interval time B can be changed because there is a difference in operation feeling between individuals.

Specifically, for example, a combination of several stages is prepared in advance, and switching is performed by a special operation of the keyboard. A combination of several stages is prepared in advance, and switching is performed by switching means (for example, a switch) provided separately. The user can arbitrarily change the set time by special operation of the keyboard. For example, when the user presses the numerical key of "4" on the keyboard after inputting the hidden command, there is a means such that the release determination time is set to 0.4 seconds.

FIG. 4 is a diagram for explaining a conventional transmission mode. As described above, conventionally, code data is transmitted by key-on, but re-transmission is not performed as in the present invention even if the key is pressed and released thereafter.

In the above embodiment, the case where the plug-in type connector is used has been described. However, the present invention is not limited to this. For example, an electromagnetic coupling type connector may be used.

[0020]

As described above, the present invention has a connector which can be connected to a portable device, and connects the keyboard and the portable device via the connector. In the keyboard input device capable of inputting to the portable device, when the key is pressed and released for a predetermined time or more, the code data transmitted by the key can be repeatedly retransmitted until the key is released. Have been.

Therefore, when repeatedly inputting the same code data, it is not necessary to repeatedly press the same key as in the prior art, and it is sufficient to keep the key pressed, so that the key operation is simple and the usability is good. is there.
