Description

TECHNICAL FIELD The present invention relates to a data input device that allows data regarding operated keys to be confirmed by voice according to desired specifications.

According to the prior art, in a data input device that selects a desired specification from among a large number of specifications and outputs data regarding the operated key to an external device according to the specification, it is possible to The configuration is such that the ROM packs for each specification in which a group of audio data is written are exchanged according to the desired specification, and the data corresponding to the operated key is output as audio according to the desired specification. This method requires time and effort to replace ROM packs accordingly, and also requires a large number of expensive ROM packs for each specification with fast access times in order to obtain high audio output responsiveness to key operations.

In addition, a large number of large-capacity memo rivers are written with audio data groups consisting of a large number of audio data corresponding to each key for each specification, and the audio data corresponding to the key operated according to the desired specification is output and the voice is output. Although a configuration that outputs 200 kHz can reduce costs, it has the disadvantage that the response time of audio output to key operations is poor because access time is slow for large-capacity memories.

Purpose The purpose of the present invention is to provide a low-cost data input device that can easily confirm data related to operated keys by voice according to desired specifications, and that can improve its operability, in view of the drawbacks of the above-mentioned system. It is about providing.

Example Hereinafter, the present invention will be explained according to examples.

FIG. 1 is a perspective view schematically showing a data input device according to the present invention. A select key 3 serves as a selection means for selecting a specification regarding a desired language from among a large number of specifications concerning languages such as English, French, German, Spanish, etc., and a character corresponding to the operated key 2a is selected. A speaker 4 that outputs audio by pronunciation according to the specified specifications, a platen 6 to which the printing paper 5 is attached, and a reciprocating motion along the printing line of the printing paper 5 to select the character corresponding to the operated key 2a. Accordingly, the dot printer 8 is an external device including a print head 7 having a large number of print wires for printing in a dot matrix format.

FIG. 2 is an electronic block diagram of the data input device. To select a desired specification from among the many specifications of the keyboard 2, operate the select key 3 corresponding to the desired specification. A selection signal SES corresponding to the selection key 3 is output to a key control circuit 9 constituting key control means.

In response to the selection signal SES, the key control circuit 9 outputs a selection instruction signal SIS for selecting a desired specification to the dot printer 8 and the memory control circuit 10 constituting the memory control means.

When the dot printer 8 outputs the input selection instruction signal SIS to the dot pattern memory control circuit 11, the dot pattern memory control circuit 11 outputs the selection instruction signal S.
In response to the IS, a large-capacity disk, drum, floppy disk, etc., in which a large number of dot pattern data groups consisting of a large number of dot pattern data forming characters corresponding to each key 2a are written for each specification. Dot pattern data groups DPG with specifications corresponding to the select key 3 are sequentially output from the dot pattern data group memory 12 consisting of an optical disk, magnetic baffle, magnetic tape, etc., and each dot pattern data DPD of the dot pattern data group DPG is is written in the memory portion corresponding to each key 2''a in the dot pattern data memory 13, which is rewritable and has a longer access time than the dot pattern data group memory 12, such as a non-volatile random access memory. In addition, the memory control circuit 10 responds to the selection instruction signal SIS and generates a voice pattern consisting of a large number of voice patterns composed of digital signals related to the pronunciation of characters corresponding to each key 2a for each specification. A voice pattern with specifications corresponding to the select key 3 is obtained from the first memory 14, which has a large capacity in which a large number of data groups are written, such as a disk drum, floppy disk, optical disk, magnetic bubble, or magnetic tape. A non-volatile random access memory, for example, capable of rewriting a data group VPG and rewriting each voice pattern data VPD of the voice pattern data group VPG, and having a faster access time than the first memory 14 and a capacity of 4 - Each key 2 in the second memory 15 consisting of a memory etc.
Write to each memory portion corresponding to a.

Note that the dot pattern data memory 3 and the second
In each storage portion of the memory 15, a large number of pattern data from the first data to the last data constituting the dot pattern data DPD and the voice pattern data VPD are stored. Next, in order to input a character by operating the key 2a according to the specifications selected by the above operation, the key control circuit 9 outputs a search signal SC to the keyboard 2, and uses the search signal SS input from the keyboard 2 to input a character. The operated key 2a is detected and a code signal CS corresponding to the key 2a is output to the dot printer 8 and the memory control circuit 1, respectively. The dot printer 8 sends the input code signal CS to the dot pattern memory control circuit 11.
When output to the dot pattern memory control circuit 11
outputs the start address signal AS of the storage part in which the dot pattern data corresponding to the code signal CS is stored to the dot pattern data memory 13, and outputs the dot pattern data DPD corresponding to the code signal CS to the operated key. The first data is read from the storage part corresponding to 2a, and then the address signal AS is sequentially incremented to the address where the last data is stored to read each data, and the dot pattern data DPD is output to the dot printer 8. , the characters corresponding to the operated key 2a are printed in a dot matrix format according to the selected specification.

Further, in response to the input code signal CS, the memory control circuit 9 outputs, to the second memory 15, the start address signal AS32 of the storage portion in which the audio pattern data corresponding to the code signal is stored, The first data of the voice/miturn data VPD corresponding to the operated key 2a is retrieved from the storage section corresponding to the key 2a, and then the address signal AS2 is sequentially incremented by the address E where the final data is stored. The data is presented and output to the audio output circuit 16.

The audio output circuit 16 converts the audio pattern data VPD into an audio signal VS consisting of an analog signal by the audio conversion circuit 17.
After D/A converting the audio signal VS into audio amplification circuit 1
8 and outputs it to the speaker 4, and the character corresponding to the operated key 2a is outputted as a sound according to the selected specification.

Therefore, this embodiment has the following features. '1} Since the first memory 14 has a large capacity and slow access time, it is possible to reduce the cost of the data input device. {2' second
The memory 15 has a small capacity and fast access time, so it can improve the responsiveness of audio output to key operations, and
Cost reduction can be achieved.

'3} The voice pattern data VPD is stored in the second memory 15
Since the information is written to the memory portion starting from the first address corresponding to each key 2a, in addition to the above feature '3', address control can be simplified, access time can be sped up, and responsiveness can be improved.

'4} Also, since non-volatile random access memory is used as the second memory 15, even if the data input device 1 is turned off, it will not be necessary to turn off the power.
The voice pattern data VPD corresponding to the previously selected specification and written in the second memory 15 is held.

'51 Since the characters related to the operated key 2a are outputted in a voice according to the desired specifications, the printed characters can be confirmed extremely easily and the operability thereof can be improved.

It should be noted that even if the present invention is modified as described below, it is still within its technical scope.
