Abstract

PURPOSE:To prevent erroneous input by generating a key operating tone to each input mode in the key input device having plural input modes so as to inform the present input mode to the operator. CONSTITUTION:When any of input mode designation keys 3, 4, 5 and 6 is operated, a signal is outputted to an input mode selecting circuit 7 via signal lines l1-l4, the present input mode is selected by the signal and also a key signal corresponding to the input mode is outputted onto a signal line l5. Each drive terminal of oscillating circuits 10-13 having different frequencies f1-f4 is connected respectively to the terminals t10-t13 of a switching circuit 9, and each output is connected to a oscillation body 14. When the input mode selection key 3 is operated, the oscillation circuit 10 is driven and the signal in the frequency f1 is generated from the oscillation body 14 at each key operation of a key group 2.

Description

TECHNICAL FIELD The present invention relates to a key-powered device, and more particularly to a key-powered device having multiple input modes.

(Prior Art) Currently, various input methods have been proposed and implemented for key-powered devices for inputting Japanese including kanji. For example, the Taiguchiita type key-powered device has input modes such as food input, single kanji selection, kana-kanji conversion, romaji kana-kanji conversion, kanji delimiter conversion, and two-clause delimiter conversion, each of which has its advantages and disadvantages. Nowadays, many key-powered devices have multiple input modes among the above.
In most cases, the operator selects and inputs one input mode as needed.In such a key-powered device, there is an LED to indicate the selected input mode.
The current input mode is displayed on the CRT, but as operators become more skilled, when using blind touch, they may input in a different input mode without noticing the incorrect input mode. This has the disadvantage of reducing input efficiency.

(Purpose) The present invention was made in order to eliminate the drawbacks of the key-powered devices having multiple input modes as described above. The object of the present invention is to provide a key manual device that reduces erroneous input by notifying the input mode of the key.

(Embodiment) An embodiment of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of a key-powered device according to the present invention. In FIG. There are input mode designation keys 3 to 6 for varying functions. Each of the input mode designation keys 6 to 6 is an input mode designation key for, for example, food input, single kanji selection input, kana-kanji conversion, and o-maji kana-kanji conversion.
Such key group 2 and input mode designation keys 3, 4, 5
6 is input to an electronic device (not shown) through signal lines L1 to L5, and data corresponding to a designated input mode is input.

When any of the input mode designation keys 3, 4, 5.6 is operated, signals are output to the input mode selection circuit 7 via the signal lines 11 to 14, and the current input mode is selected by these signals. At the same time, a key signal corresponding to the input mode is output onto the signal line ts. The input mode selection circuit described above discriminates the signals outputted through the signal lines 11 to 8, and inputs a signal for controlling the connection of the terminals of the swinging circuit 9, which will be described later, according to the discrimination result. W line ls
K outputs 0 10 to 16 indicate oscillation circuits that oscillate different frequencies f1 to f4, and the drive terminals of each oscillation circuit 10 to 13 are connected to terminals t10 to i1g of the switching circuit 9, The output of each oscillation circuit 10-16 is connected to an oscillator 14 such as a speaker.

The switching circuit 9 controls the connection between the connection terminal tea and the connection terminal tlo-tts using a signal coming through the signal line 16. For example, when a signal is input to the input mode selection circuit 7 by operating the input mode designation key 6, the cane input mode selection circuit 7 determines the signal and connects the terminal too and the terminal tx4 of the switching circuit 9. A control signal is output onto the signal line 16 for connection. Similarly, when the input mode selection keys 4, 5.6 are operated, the switching circuit 9 connects the signal line /6 to the terminal t.
14 and each terminal txt, txt, txs.

In the key-powered device configured as described above, when the input mode selection key 3 is operated, the switching circuit 9 connects the terminal txo and the terminal t1a, and connects the oscillation circuit 10 and the signal line l. Similarly, when the other input mode selection keys 4°5.6 are operated, 1 is generated by operating the selection keys 4°5.6, respectively. The oscillator 14 generates an audible frequency signal having a critical wave number.

(Effect) As explained above, according to the present invention, it is possible to generate different key operation sounds depending on the input mode in a key-powered device having a plurality of input modes, so it is possible to prevent input mode selection. This enables early detection and improves input operation efficiency.
