Description

[Detailed Description of the Invention] [(Already needed) The present invention relates to a keyboard device, and is a keyboard device that generates a key code by pressing a key and sends it to the main device, with the aim of reducing the burden on the main device. The system includes a non-volatile memory in which a series of key codes are registered, and a sending means, and the sending means transmits the series of key codes from the non-volatile memory when the main unit becomes available for use. The configuration is such that the information is sequentially read out and sent to the main unit. Further, the configuration is such that a key code generated when the main unit is in a receivable state is queued, and the queued key code is sent out when the main unit is in a receivable state.

[Industrial application field]

The present invention relates to improvements in keyboard devices.

When starting to use a computer device, after operating the keyboard and entering the user ID, password, etc.
It is necessary to start an application program, and in order to simplify this operation, functions such as automatic login and automatic start-up are provided on the device side.

It also has a function to receive and queue key codes even if the number of key codes transferred from the keyboard cannot be processed.

In this way, recent computer devices are not equipped with functions to simplify keyboard operations, which puts a burden on the devices, and when automatic login/automatic application startup functions are used, specified Since the application is automatically executed when the power is turned on, there are problems such as the device being used for personal use.

Therefore, there is a need for a keyboard device that solves these problems.

[Conventional technology]

FIG. 5 is a configuration diagram of a conventional example.

FIG. 5 shows an example of a computer device configured to notify the start of use by a login operation of inputting a user ID and password, and has an automatic login function and an automatic application startup function.

It has a queuing function.

To start using the device, when the power is turned on, a login screen is first displayed on the display unit 9, and according to this display screen, the operator inputs the user 10. Create passwords manually.

Thereby, the management unit 4 receives the input user ID.

Password and registered 10. Compare with the password,
If there is a match, the state is set to usable (usage permitted).

At this time, if "Automatic Login" is set, that user 1
0. A login command with a password is registered in the disk device 2, and thereafter, it is referenced when the power is turned on and the user is automatically logged in.

Subsequently, when a command to start an application program is input, the management section 4 reads the specified program program 1 from among the application programs APL PROG stored in the disk device 2 into the memory 3 and starts it.

Similar to automatic login, the startup of this application can also be automated by registering separately. Therefore, if you set both automatic login 1 and automatic application functions, the application program you set will automatically start when the power is turned on. is executed.

When an application program is running and data is input from the keyboard 8, the key code processing on the main device 1 side may not be able to follow the key pressing speed.

Therefore, the key codes received through the interface circuit (IF circuit) 6 are stored in the queuing memory 5 and queued (waiting), and when an input request is received from the application program, the key codes are sent from the queuing memory 5 in the order of input. It is designed to read and pass the key code.

[Problem to be solved by the invention]

As mentioned above, in recent computer equipment, command (5
Although we have simplified operations by automating manual labor and queuing key code input, there are problems with logins and logging in.

Automating application startup makes the computer device personal.

In view of the above problems, the present invention does not place a burden on the main body device,
Another object of the present invention is to provide a keyboard device that eliminates personalization of the main unit and automates operations.

[Means to solve the problem]

In FIG. 1, a diagram showing the principle of the present invention, 7 is a non-volatile memory in which a series of key codes are registered.

Reference numeral 30 denotes a sending means, which sequentially reads out a series of key codes from the nonvolatile memo January 7 and sends them to the main device 1 when the main device 1 becomes usable after IPL.

[For production] A login command is written to the non-volatile memory 17 in advance.

Register a series of key codes that constitute application program startup commands, etc.

When the main body device 1 becomes usable due to power-on, etc., the sending means 30 reads this series of key codes from the nonvolatile memory 17 and sequentially sends them to the main body device 1.

As a result, the main device 1 performs login processing if the series of key codes are for a login command, and if the series of key codes input subsequently is for a startup command of an application program, the main unit 1 performs login processing from a file, etc. Load and start the program.

As described above, the keyboard device can have the automatic login and automatic application startup functions that were conventionally provided in the main device 1, and can be excluded from the main device 1, reducing the burden. If the keyboard device 1 is made removable, no matter which computer device it is connected to, the automated processing unique to that keyboard device will be performed, and the main body device 1 will not be dedicated.

Furthermore, if the keyboard device is provided with a queuing function and the key code that has been queued is sent out when the main device 1 becomes ready, there is no need to provide the queuing function in the main device 1. The burden on the main body bag W1 can be reduced.

〔Example] Embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 2 is a configuration diagram of one embodiment, FIG. 3 is an automatic login/automatic application startup operation time chart, and FIG. 4 is an operation time chart during queuing.

In this embodiment, a keyboard device is shown that has an automatic login function, an automatic application startup function, and a queuing function.

In the keyboard 10 of the present invention shown in FIG. 2, 11 is an interface circuit that exchanges data with the main device 1.

12 is a status register in which the ready state and busy state notified from the main device 1 are set.

15 is a non-volatile memory ROM in which a control program 22 executed by the processor 13 is stored.

Reference numeral 16 denotes a queue memory in which key codes generated when the main unit 1 is in a busy state are queued.

Reference numeral 17 denotes a writable non-volatile memory in which a series of key codes, here a login command and a series of key codes forming an application program startup command, are registered.

18 is the key part, and processor 1 receives an interrupt when the key is pressed.
3, the pressed keys are read and a key code is generated.

The interrupt circuit 13 I4 is a processor that executes a control program 22 and controls the above-mentioned units connected to the bus 20.

22 is a control program that performs key code generation, queuing, key code sending processing, etc.

21 is a detachable connection cable that connects the keyboard device 10.
and main unit 1 are connected.

In addition, the same reference numerals represent the same objects throughout the figures. Note that the sending means 30 corresponds to the control program 22.

Note that user 10. A login command and an application program startup command, which are composed of a password and the like, are registered in the nonvolatile memory 17 as a series of key codes from, for example, the key section 18 of the keyboard device 10.

In the keyboard device WIO having the above configuration, the following key code sending process is performed.

(Automatic login, automatic application startup) Refer to FIG. 3. Connect the keyboard device 10 to the main device 1 and turn on the power. The main body device 1 performs IPL processing after notifying the keyboard device IO of the busy state, and notifies the ready state after the IPL is completed.

In the keyboard device 10, this busy/ready state is set in the status register 12, and the processor 13 executing the control program 22 periodically monitors the status register 12.

When the IPL of the main unit 1 is completed and the ready state is detected, the processor 13 accesses the non-volatile memory 17, checks the ready state each time, and sequentially reads the key code for each transfer unit. Send to 1 (report)
do.

In the main device 1, when the management unit 4 recognizes a login command from a series of key codes, it performs a predetermined login process.
Then, when it recognizes the application startup command, it starts the specified program.

This allows the specified application program to be automatically executed simply by turning on the power.

(Queueing Process) FIG. 4 shows a sequence for queuing a key code generated by pressing a key by an operator within the keyboard device i10.

Each time a key is pressed, the processor 3
When an interrupt occurs, the processor 13 determines the type of key, generates a key code, and sends it to the main unit 1. At this time, if the main unit 1 is in the ready state, the key code is sent to the main unit 1 at the same time as the key code is generated, and if the main unit 1 is in the busy state, the generated key codes are queued in the queue memory in the order in which they occur.

Then, when the busy state is released, the key codes are sent out in the order of queuing.

As described above, by providing the keyboard device 10 with the function of sending out the held key code, automatic login, which was conventionally provided on the main body device 1 side, can be achieved.

The automatic application starting function and the queuing function can be provided on the keyboard device side, and therefore, these functions can be excluded from the main body device 1, so that the burden on the main body device 1 is reduced.

Furthermore, since the keyboard device 10 has the function of automatic login/automatic application startup, when this keyboard device 10 is connected to another main device, that function can be applied to that main device. It will never be of any use.

〔Effect of the invention〕

As explained above, the present invention provides a keyboard device that has automatic login, automatic application program startup functions, and key code queuing functions, which reduces the burden on the main unit and This has the effect of preventing personalization.
