Abstract

PURPOSE:To attain input independent of manual work, to shorten a data input time and to improve the efficiency of work by providing the portable type I/O device with a voice input part and a voice recognizing part for recognizing a voice input received from the voice input part, converting the voice input into its corresponding code and transferring the code to a processing/control part. CONSTITUTION:The portable type I/O device is constituted of the processing/ control part 1, a memory part 2, an external device interface part 3, a display part 4, a keyboard 5, a key input interface part 6, a case 9 for storing respective parts, the voice input part 7, and the voice recognizing part 8 for recognizing a voice input received from the voice input part 7, converting the voice input into its corresponding code and transferring the code to the processing/control part 1 to attain data input independent of manual operation. Since data input based upon manual operation such as key entry is unnecessary, the portable type I/O device can be utilized even in a working environment requiring complex manual work.

Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a portable input/output device used in a computer system, etc., and particularly relates to a portable input/output device equipped with a voice input function. be.

(Prior Art) In a computer system, data to be processed is input at a remote location or work site away from the location where the computer itself is installed, and a portable computer is used to transfer this input data to the computer system via a signal line. type I/O device is being used.

Traditionally, data input to such portable input/output devices is
This is done manually by pressing keys on a keyboard or reading barcodes using a barcode hand scanner or pen scanner.

(Problems to be Solved by the Invention) The conventional portable input/output device described above inputs data manually. For this reason, portable input/output devices cannot be used in work environments that involve busy manual labor, such as sorting products transported on a conveyor belt, and a separate worker specialized in data input is required. There is a problem.

(Means for Solving the Problems) The portable input/output device of the present invention includes, in addition to a key input section, a display section, a processing/control section, a memory section, and an interface section with an external device, a voice input section and an audio input section. It is equipped with a voice recognition unit that recognizes voice input received from the input unit, converts it into a corresponding code, and passes it to the processing/control unit, and is configured to enable data input without manual operation.

Hereinafter, the operation of the present invention will be explained in detail together with examples.

(Embodiment) FIGS. 1 and 2 are a block diagram showing the configuration of a portable data input device according to an embodiment of the present invention, and a plan view showing the external appearance, respectively.

This portable input/output device includes a processing/control section 1, a memory section 2
, an external device interface section 3, a display section 4, a keyboard 5, a key manual interface section 6, and a case 9 for accommodating these, as well as a voice input section 7 and a voice recognition section 8.
It is equipped with

The processing/control unit 1 communicates with a higher-level external device such as a computer via an external end device interface unit 3, such as characters, symbols, menus, etc. to be displayed on the 4, and data input and processed from the keyboard 5 and voice input unit 7. etc. are stored. The processing/control unit 1 reads necessary programs from the memory unit 2, edits and processes human data, and controls various units such as the display unit 4.

The key human power interface unit 6 converts key operation position information input from the keyboard into a corresponding code and processes it.
control section].

The voice input section 7 is composed of a microphone and the like, and converts the voice input from the worker into an electrical signal and passes it to the voice recognition section 8 . The voice recognition section 8 is composed of a voice recognition LSI, etc.
The electrical signal of the voice received from the voice input section 7 is divided into monosyllables, its frequency spectrum is extracted, and this is compared with a group of registered patterns of frequency spectra currently registered in the built-in memory, and the most similar one is selected. and outputs the corresponding code to the processing/control unit 1. In order to reduce the amount of memory used for speech recognition, registered patterns are limited to a small number of alphanumeric characters and kana characters, and specific speaker registration is performed.

The processing/control unit 1 processes input data in the form of a code received from the voice recognition unit 8 and the key human power interface unit 6,
It is stored in the memory section 2 and displayed on the display section 4 as input data.
to be displayed.

In this portable input/output device, for the audio input section 7 using a microphone or the like, a microphone with a cable can be used instead by providing a connector opening at the corresponding location of the main body case 9 shown in FIG. . In this case, the microphone is equipped with a clip, which is attached to the collar of the worker, and the main body is carried using a shoulder belt, thereby freeing the worker's hands completely.

(Effects of the Invention) As explained in detail above, the portable input/output device of the present invention is configured to have a voice recognition function by incorporating a voice recognition LSI, etc., so that it is possible to input data by voice. .

As a result, manual input of data such as keystrokes is no longer essential, and the portable input/output device can be used even in business environments that require busy manual work.

Furthermore, even if busy manual work is not required, changing from manual key input to voice input can shorten data input time and improve work efficiency.

Furthermore, inputting data by voice has the advantage that input errors that tend to occur due to manual key operation errors can be reduced.
