Description

[Detailed Description of the Invention] [Summary] This invention relates to a wireless information receiving section of an information processing device that includes a main body that processes input information and an input means that wirelessly inputs information to the main body. For the purpose of preventing interference and improving usability when placed in close proximity, there is a wireless information receiving section that receives wireless information from the outside, and a wireless information receiving section that is connected to the wireless information receiving section and receives wireless information received by the wireless information receiving section. In the information processing device, the wireless information receiving section is configured to be detachable from the main body.

[Industrial application field]

The present invention relates to an information processing device that includes a main body that processes input information and input means that wirelessly inputs information to the main body, and particularly relates to an improvement of a wireless information receiving section thereof.

Personal computers have become more compact with the help of semiconductor technology, and one computer per person is now being installed in offices. In such cases, a dedicated computer desk was previously required, but now compact computers have become possible to be installed on each person's desk.

If each person uses the keyboard on a desk, a wired keyboard would get in the way, so it is desirable to have a wireless keyboard.

[Conventional technology]

Conventionally, a wireless keyboard using optical signals or electromagnetic wave signals has been used as an input means for wirelessly inputting information to a main body of a device that processes input information.

[Problem to be solved by the invention]

Conventional wireless keyboards pose practical problems when multiple keyboards are installed in close proximity to each other, causing interference and preventing normal key input. When interference occurs, data from an adjacent keyboard may be input, or normal data may overlap with data from another keyboard, causing a framing error.

In addition, in order to avoid reception interference with such wireless information processing equipment, the main body and the keyboard are sometimes used by directly connecting them via a cable. Since the cable connecting the main body and the keyboard was prepared separately and stored in a separate location from the device, it was difficult to use due to problems such as being lost or forgetting its shape when transporting the device.

The present invention has been made in view of the drawbacks of the prior art described above, and an object of the present invention is to provide a wireless information processing device that prevents interference and improves usability when a plurality of devices are arranged close to each other.

[Means to solve the problem]

In order to achieve the above object, the present invention includes a wireless information receiving section that receives wireless information from the outside, and a main device that is connected to the wireless information receiving section and receives the wireless information received by the wireless information receiving section. In the information processing device including the wireless information receiving section, the wireless information receiving section is configured to be detachable from the main body device.

Further, in the present invention, in an information processing device comprising a device main body for processing information and a wireless keyboard for wirelessly inputting information into the main body, the receiving section of the main body is attached so as to be removable from the main body via a cable. The receiving unit is configured to be attachable to the wireless keyboard I7.

[For production]

If a large number of devices with wireless information receiving units (receiving units) are installed, or if natural light etc. cause problems with key input, remove the wireless information receiving units (receiving units) from the main unit and use other devices. Set it in the optimal position to avoid interference from other sources.

This makes it possible to reduce the probability of the above-mentioned framing error to a level that poses no problem in practice. Note that the second feature of the present invention is that the receiving unit is equipped with an ID.
By providing a means for inputting information and performing processing that does not accept input signals other than those from a set keyboard, it becomes possible to prevent incorrect data from being input. As a third feature of the present invention, when an ID is registered, erroneous input can be easily confirmed by displaying whether incorrect ID information has been input.

The receiving unit is connected to a wireless input means (W10
By attaching the keyboard to a glossless keyboard, the main body and the keyboard can be connected with a cable, and signals can be transmitted virtually through the cable.

Perform 2 scanning. The ID is registered by inputting the two-digit number following the key on the numeric keypad 7 on the receiving unit.

The registered ID is held in the ID storage holding unit 7. Furthermore, once the ID is registered, an ID validity flag 18 is turned on to enable checking of the ID until the power is turned off. When the microprocessor 11 receives the signal from the receiving section, it refers to the ID validity flag 18 and causes the display LE013 to emit red light if the IDs do not match. On the other hand, if the IDs match, it is issued in green and key input data is transmitted to the main unit via the driver 16.

The data transmission interval is shown in FIG. 6, and the data format is shown in FIG. 7.

In FIG. 5, the data is sent out in the order of B7...BO. The key data from the wireless keyboard has a 2-byte structure and is transmitted at the intervals shown in FIG. Note that the code of the last pressed key is sent out at intervals of 20 m5 until the key is released. Further, as a feature of the present receiving unit, ten-key keyboard input is possible for each receiving unit, and it is also possible to realize a keyboard-less application. With the above functions, it is possible to determine the data input and interference situation at a glance, making it easy to set the optimal position and angle for installing the separate receiving unit, completely preventing incorrect input. can do.
