Abstract

PURPOSE:To improve operability and to reduce the number of errors by controlling plural shifting states specified by a shifting means in response to the input of information to one and visualizing the controlled state. CONSTITUTION:When a name is to be retrieved, the operator turns on a lock key 14 to provide the secondary information from the 2nd indicating means 3. At the time turning on the key 14, a name retrieving instruction is generated, waveform change is applied to a differential circuit 16 and a setting signal is applied to an FF9. The FF9 applies a signal indicating that data A [kana (Japanese syllabary) characters] can be outputted by a signal generating means 4 to a display device 18 and sends a control signal to an AND gate 5 for controlling the output of the data A, so that the AND gate 5 is opened and the data A are outputted. Consequently, the operation of the 1st indication key (shift key) 2 for switching information generated by an input means 1 can be omitted.

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an input device that can input a plurality of pieces of information with a simple operation, particularly in a device that generates a plurality of pieces of information using one input means.

2. Description of the Related Art Conventionally, for example, the key of an information retrieval device In a human-powered device, when the input information consists of kana characters and English characters, these keys are used as an instruction means to instruct which information to input on the keyboard. was controlled by. However, information retrieval devices need to know how to process the information that will be input. For example, should you search by name/name (kana characters) or by account number/name?
In some cases, information on whether to search for a person's name code, etc. (alphanumeric characters) is provided, and a key is provided for that purpose. Select what to search using the key, and then select the information as kana characters or alphanumeric characters. It is done manually.

In conventional devices of this kind, the operator checks whether the input means that generates multiple pieces of information (kana characters or alphanumeric characters) generates kana characters or alphanumeric characters.
The first action that must be taken when inputting information is to know whether the instruction means is the original input instruction.

Such actions place a burden on the operator, and when a kana character search is followed by an alphanumeric search, even if the search information is provided satisfactorily, it is unclear whether the switching operation between the means for generating kana characters or alphanumeric characters is performed satisfactorily. I don't know.

In view of the above-mentioned points, the present invention includes an information input means for inputting information, a shift input means for specifying a plurality of shift states, and responsive to information input from the information input means,
control means for causing a predetermined one of the plurality of shift states specified by the shift input means;
The present invention provides an input device having an input device having a means for visualizing the predetermined one thing by the control means.

Other objects of the input device according to the present invention will become clear from the detailed description given below in conjunction with the drawings.

The input device according to the present invention will be explained below with reference to the drawings.

) and alphanumeric characters (hereinafter referred to as DataB),
It is connected to one input terminal of each AND gate 5.6. Reference numeral 7 denotes an input terminal into which a signal generated by the first instruction means 2 is input. This input terminal 7 is connected to a differentiating circuit 8, and the differentiated pulse obtained from the differentiating circuit 8 is applied to the two input terminals of a flip-flop 9 (or-game)10.
The output of the flip-flop 9 is supplied to the input terminal of the AND gate 5 which controls the output of DataA, and the inverted signal of the flip-flop 9 input to the AND gate 5 is obtained by the inverter 12. ,
The output is supplied to an AND gate 6 that controls the output of DataH. The output of AND gate 5.6 is OR gate 1
3 is entered. 14.15 is a lock key showing a specific example of the second instruction means shown in FIG. 1, which outputs a command to close the circuit, a command to start a name search, an account search, that is, secondary information, and a differential circuit. The circuits 16 and 17 are connected to apply a waveform change caused by the closing or ON of the lock key, and to apply a differential pulse to the flip-flop 9 via an OR circuit 10 and 11.

Also, is Data A outputted from the signal generating means 4 which causes a plurality of primary information to be generated from one of the input means l?
An input signal to a display device 18, 19 provided on the console of the information retrieval device for displaying whether Data B is output is connected to be obtained from the output of the flip-flop 9. 18 is Data A, 19 is Data D
This is to notify the operator that the ata B is capable of outputting by lighting or blinking a lamp or LED.

The operation of an embodiment having the above configuration will be explained with reference to the drawings.

If we now perform a name search, the operator will
The lock key 14 is used to provide secondary information using the instruction means 3.
Turn on. When the lock key 14 is turned ON, a name search command is generated and a waveform change is applied to the differentiating circuit 16.
Add a set signal to flip-flop 9. Therefore, the flip-flop 9 applies a signal to the display device 18 indicating that Data A (kana characters) can be output from the signal generating means 4, and also sends a control signal to the AND gate 5 which controls the output of [1data A]. AND gate 5 is opened and l1ata A is output.

Therefore, it is possible to omit the operation seen when operating a conventional information retrieval device, that is, the operation of operating the first instruction means, that is, the shift key, in order to switch the information generated by input ① before performing a name search. .

Account search, that is, alphanumeric search, is performed in the same manner as described above, and first, the second instruction means 3 turns on the long key 15 to give a search command. Therefore, it is inverted by the output of the differentiating circuit 17 together with the search command. As a result, the AND gate 5 and 6 which control the output of the next information are closed so that Data B can be output, and the AND gate 6 is closed so that Data B can be output.
will be developed. Furthermore, the display device 19 lights up to indicate that Data B can be output. After this operation, primary information is given by the input means 1 and a search is performed.

As understood from the above description of the operation, the operator does not need to switch the primary information generated by the input means 1 every time the name search account search or the search object changes.

The shift key, which is the second indicating means 3, is used when it is necessary to switch the primary information in a name search such as Misenamas 5M Nina, for example. By operating the first indicating means 2, the shift key A to DD
ATA B, the first instruction means 2 is operated to apply a signal to the differentiating circuit 8, and the output from the differentiating circuit 8 is applied to the flip-flop 9 via the OR circuit 1O111, and the AND gate circuit 5 .6 changes, Data
B becomes able to output and flip-flop 9
The output of this causes the display device 19 to light up.
