Abstract

PROBLEM TO BE SOLVED: To selectively use many functions by changing only a wireless unit without changing a keyboard by fitting the wireless unit to the keyboard so as to use as a wireless keyboard. SOLUTION: A data signal is inputted to a connection part 13 provided on the housing part 14 of the wireless unit 11 by the keying operation to the key top of the keyboard. On the other hand an X-Y signal is inputted to the connection part 13 provided on the housing part 14 of the wireless unit 11 through a cable by the X-Y operation of a mouse. The data signal and the X-Y signal inputted to the wireless unit 11 are converted into a radio signal by a conversion part housed in the housing part 14. Then the converted data signal and X-Y signal are transmitted from a transmission/reception part 12 to a computer as the radio signals. A signal from the computer is received by the transmission/reception part 12 and transmitted to the keyboard and the mouse through the conversion part within the housing part 14.

Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to an input device for inputting data to a computer or the like. For example, it relates to making a keyboard and a mouse wireless.

[0002]

2. Description of the Related Art Conventionally, a keyboard 1 shown in FIG. 4 has been known as an input device of this type. The keyboard 1 inputs data with the key top 3 and inputs the data to the computer through the cable 2.

When the keyboard 1 is used to input data to a computer by a radio signal, a circuit for converting the data entered by the key top 3 into a radio signal, a signal transmitting / receiving device, and a driving battery are placed in the keyboard. It was built and integrated. Also, not only wireless signals but also data may be input with a cable, so the function to switch between wireless and wired is added to the keyboard, and the infrared wireless keyboard cannot be used as a radio wireless keyboard. I was making a keyboard for each method, and I was also making a keyboard for each national language version.

[0004]

However, in the keyboard having the above-mentioned structure, when switching from the wired type to the wireless type, a new switching function has to be added, and the infrared wireless type, If you want to use both radio and wireless type, you also have to purchase a keyboard of each type. In addition, especially in a method with limited directivity such as an infrared wireless system, since the mounting position of the transmitting and receiving part is fixed to a part of the keyboard, there is a problem that the degree of freedom of operating position is low and the usability is poor. Come on. There is also the problem that it costs money to make a keyboard for each language version.

[0005]

According to the present invention, a transmission / reception unit for transmitting / receiving a radio signal to / from a computer, and a conversion for converting an input signal of an input device such as a keyboard and a mouse connected to the transmission / reception unit into a radio signal. This is achieved by providing a separate keyboard unit with a wireless unit including a unit, a connection unit electrically connected to the input device, and a storage unit that stores a battery that drives the transmission / reception unit and the conversion unit.

Further, it is achieved by providing the above-mentioned wireless unit with an attachment holding mechanism that can be attached to a keyboard.

DETAILED DESCRIPTION OF THE INVENTION The present invention will be described below with reference to the drawings. FIG. 1 is an example of an embodiment of a wireless unit according to the present invention. In the figure, 12 is a transmission / reception unit for transmitting / receiving a wireless signal to / from a computer, 13 is a connection unit for connecting cable terminals of a keyboard and a mouse, 14 is a conversion unit for converting an input signal of the keyboard and a mouse into a wireless signal, and a transmission / reception unit. 12, a housing for accommodating a battery for driving the converter, and 15 a mounting and holding mechanism for mounting on the keyboard.
3, the housing unit 14 forms the wireless unit 11.

A state in which the keyboard 1 and the mouse 4 are connected to the wireless unit 11 having the above structure will be described with reference to FIGS. 2 and 3.

In FIG. 2, the keyboard 1 and the cables 2 and 5 of the mouse 4 are connected to the wireless unit 11 and the connecting portion 1 is formed on the housing 14 of the wireless unit 11.
3, and the connected wireless unit 11 is attached to the keyboard by the holding mechanism section 15. The holding mechanism unit 15 includes the housing unit 1.
The wireless unit 11 is attached to the keyboard by elastically deforming the elastic pieces 15a and 15b and sandwiching the elastic pieces 15a and 15b in the keyboard frame. Moreover, the attachment position is attached to an arbitrary position of the keyboard.

A data signal is input to the connecting portion 13 provided in the housing portion 14 of the wireless unit 11 through the cable 2 by driving the key top 3 of the keyboard 1 into operation. In addition, an XY signal is input by the XY operation of the mouse 4 through the cable 5 to the connection portion 13 provided in the housing portion 14 of the wireless unit 11.

The data signal and the XY signal input to the wireless unit are converted into a wireless signal by the conversion unit housed in the casing 14. Then, the converted data signal and XY signal are transmitted from the transmitting / receiving unit 12 to a computer (not shown) as a wireless signal.

The signal from the computer is transmitted and received by the transmission / reception unit 12
Received by the keyboard 1 through the conversion unit in the housing unit 14,
It is transmitted to the mouse 4.

Here, the conversion section in the casing section 14 is a circuit section, and is not limited to the above-mentioned conversion into a radio signal, but also a circuit such as conversion from an infrared system to a radio system, mutual language conversion, etc. It may be added to form one unit or may be formed into a plurality of units.

In the above description, the conversion from a wired signal to a wireless signal has been described. However, when transmitting a wired signal to a computer, the cable 2 is provided in advance as shown in FIG. 4, the wireless unit is removed, and the cable is removed. 2 is connected to a computer and used.

FIG. 3 shows an example in which the wireless unit 11 is detached from the keyboard 1 and used. in this case,
It is used at a convenient location for the user, such as the space used.

In the above description, the keyboard and the mouse are described, but the present invention is also applied to the input device such as the joystick and the trackball.

[0017]

As described above, since the input signal of the input device such as the keyboard and the mouse is transmitted as a radio signal to the computer by using the wireless unit according to the present invention, the wireless unit is attached to and integrated with the keyboard. , It can be used as an integrated wireless keyboard, and by adding functions such as conversion between infrared and radio waves and conversion between different languages in addition to the exchange of wireless and wired in the conversion unit in the wireless unit, wireless Many functions can be selected and used without changing the keyboard by changing only the unit. Also, especially in the method with limited directivity such as infrared method, the directivity is improved by changing the position of the wireless unit. There are advantages such as being able to.
