2. Description of the Related Art A key input device of an information processing device such as a word processor is, for example, a key switch assigned to a lower case alphabet in a steady state in order to enable input of various characters and symbols with a limited key switch. Every time you switch with the shift lock key, you can input characters and symbols in non-steady state (alphabet capital letters, hiragana, katakana, etc.). For this reason, the steady state of the shift lock key is stored, and when the absence of key input is detected for a certain period of time, the state of the lock key is stored and returned to the stored steady state (for example, Japanese Patent Laid-Open No. Hei 4). -199213) is proposed.

[0003]

However, in such a key input device, if the information processing device main body does not have a function for protecting confidentiality, a person other than the operator can easily operate it. There was a problem of being lost. or,
If the setting of the key input state desired by the operator is different from the initial steady state, the key input state must be set each time the operation is performed. Further, if the information processing device does not have a function of individual key setting, when a plurality of operators use the same information processing device, it is impossible to set an individual key input state desired by each operator. was there. The present invention has been made in view of the above problems, and it is possible to easily restrict access to an information processing device by a person who does not have an operation right with a password without imposing a load on the information processing device main body. The purpose is to operate in the desired key input state without being aware of the key input state setting.

[0004]

In order to achieve the above object, the present invention has a password storing means for storing a password, a password inputting means for inputting a password when a key is input, and a password input by the inputting means. And a key signal generating means for generating a key signal only when the input password is identified as valid by the password identifying means.

Further, the key input device has an individual key setting means for setting a key input state corresponding to a password, and an individual key storage for storing the key input state set by the individual key setting means in association with the password. Means and an individual key state changing means for changing the key input state to the key input state stored in the individual key storage means when the entered password is identified as valid by the password identifying means.

Further, the key input device has a time keeping means for setting and storing a predetermined time and a key input state when there is no key input for a predetermined time set and stored by the time keeping means when the key input state is an individual key state. It is more preferable to include a key input state switching means for switching to a state for inputting a password.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be specifically described below with reference to the drawings. FIG. 1 is an example of a system outline diagram showing an outline of a key input device. Reference numeral 101 denotes a key input device, which is connected to the information processing device main body 102. The key input device 101 includes an input unit 103 and a state switching unit 10
4, password storage processing unit 105, password storage unit 1
06, password identification unit 107, individual key input state setting unit 108, individual key input state storage unit 109, individual key input state changing unit 110, predetermined time setting unit 111, predetermined time storage unit 112, key state changing unit 113 .

The input unit 103 is for inputting a key signal such as a normal key signal, a password signal, and an individual key input status signal. The state switching unit 104 includes the input unit 1
03 receives the key signal from the password identification unit 10
7. According to an instruction from the individual key input state changing unit 110 or the like, the key signal is transmitted in a state in which the state is switched to the information processing device main body 1
It is for sending to 02. Also, the state switching unit 10
Reference numeral 4 also serves to send a corresponding key signal to the password storage processing unit 105, the individual key input state setting unit 108, or the individual key input state changing unit 110 according to the content of the key signal.

The password storage processing unit 105 is for storing the password information in the password storage unit 106 when there is an input for password registration, and the password identification unit 107 is for inputting a password. In this case, the password information is compared with the password information stored in the password storage unit 106, and the result is sent to the state switching unit 104.

When there is an input for setting the individual key input state, the individual key input state setting unit 108 associates the individual key input state data with the password stored in the password storage unit 106 and outputs the individual key input state data. The individual key input state changing unit 110 stores the individual key input state data stored in association with the input password in the state switching unit 10.
It is for sending to No. 4.

The predetermined time setting unit 111 changes the key signal generation state to the password input state when no key is input for a certain period of time. The data is stored in the storage unit 112 for a predetermined time, and the key state changing unit 113 measures the time stored in the storage unit 112 for a predetermined time, and when the time has elapsed, changes the key state to the password input state. This is for instructing the state switching unit 104 to do so.

Here, it is desirable to provide a non-volatile storage medium in each of the storage units of the password storage unit 106, the individual key input state storage unit 109, and the predetermined time storage unit 112.

Next, a series of processes performed by the key input device of the present invention will be described with reference to the flow chart of FIG. First, as an initial state, the key state in the state switching unit 104 is a password input state. In this state,
The operator inputs the password already stored in the password storage unit 106 from the input unit 103 (201). The entered password is stored in the password identification unit 107,
It is compared with the password already stored in the password storage unit 106 (202). If there is a matching password, the entered password is judged to be valid. On the other hand, if there is no matching password, it is judged that the entered password is not valid and the password input state is restored. When it is determined that the input password is not valid, it is determined that the subsequent key input signal is invalid, and the signal is not sent from the state switching unit 104 to the information processing device body.

Next, when it is determined that the entered password is valid, the individual key input state changing unit 110
The individual key input state setting unit 109 searches the individual key input state data stored in the individual key input state storage unit 109 in association with the password and retrieves the data (203). Here, the individual key input state data is data relating to the key input state desired by the operator when the operator inputs a key. For example, in addition to inputting characters such as "Hiragana", "Katakana", "alphanumeric characters",
Typeface of characters to enter, such as “Mincho” or “Gothic”
The size of characters to be input such as "full-width" and "half-width", "Romaji input" and "Hiragana input", and the conversion mode of characters in Kana-Kanji conversion of a word processor. The operator selects these and sets desired individual key input state data. Then, the individual key input state changing unit 110 sends the fetched data to the state switching unit 104 (204).

Next, the state switching unit 14 switches the key input state based on the individual key input state data sent from the individual key input state changing unit 110 so as to generate a key signal according to the individual key input state. . As a result, the key signal is generated, that is, the operator can send the key information to the information processing apparatus body 102 in a desired key input state (205).

The key state changing unit 113 always monitors the key input by the operator in the key signal generation state, and measures the time from the last key input. Then, the measured time is compared with the data of the predetermined time set by the predetermined time setting unit 110 and stored in the predetermined time storage unit 112 (206). When the measured time is longer than the predetermined time, the key state changing unit 1
13 sends the data to the state switching unit 104, and the state switching unit 104 switches the key signal generation state to return the key state to the initial password input state.

As described above, according to the key input device of the present invention, by providing the key input device with means for generating a key signal by inputting a password, a load is placed on the main body of the information processing device. It is possible to easily restrict access to the information processing device by a person who does not have the operation right by using the password without making a call. Further, by simply replacing the key input device according to the present invention with the existing key input device without modifying the information processing equipment body or changing the setting,
The functions according to the present invention can be easily implemented. Furthermore, since the individual key input state can be set at the same time that the access right to the information processing device is obtained by the password, the operator does not have to be aware of the key input state setting
It can be operated in a desired key input state. Further, when the operator does not operate the information processing device for a predetermined period of time or longer, the password is again required to be in the key input state, so that the access of the person other than the operator is restricted after the access right is acquired by the password. be able to.
