Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a personal computer input device such as a mouse, and more particularly to a personal computer input device having a time correction function of a personal computer built-in clock.

[0002]

2. Description of the Related Art As a technique for automatically correcting the time of a clock incorporated in a personal computer, as disclosed in Japanese Patent Laid-Open No. 9-319460, an FM multiplex broadcast receiving circuit for obtaining time information is provided in the personal computer itself. As built-in (first conventional example), as disclosed in Japanese Patent Laid-Open No. 10-31083, a personal computer to which a GPS receiver for time information acquisition is connected via an RS232C cable (second)
Conventional example), which acquires time information from another computer connected via the network disclosed in the publication (3rd example)
Conventional examples) are known.

[0003]

In the first conventional example, a special-purpose personal computer is newly purchased, or
The FM multiplex broadcast reception card must be installed in the PC body only to correct the time of the PC built-in clock.
It is hard to say that it is cost effective.

In the second conventional example, although it can be applied to the existing personal computer as it is, it is not possible to connect the GPS receiver to the personal computer main body via the RS232C cable only for the time correction of the personal computer built-in clock. However, it is still not a good idea in terms of cost effectiveness. In addition, occupying the RS232C connector of the personal computer for such purpose significantly impairs the system expandability of the personal computer.

In the third conventional example, a network connection is required each time the time is adjusted, and therefore a personal computer of a stand-alone type cannot handle it, and in addition, it is responsive due to a delay in network connection time. Inferior, there is a possibility that the time adjustment timing is not constant.

The present invention has been made by paying attention to the above-mentioned problems in the conventional automatic time adjustment technology for a personal computer built-in clock. The purpose of this invention is to attach a special accessory device to the connector of the personal computer. , It is to be able to correct the time of the internal clock of the personal computer to the correct time at any time without connecting the personal computer to the network.

Another object of the present invention is to make it possible to correct the time of the personal computer built-in clock to an accurate time at a time controlled or at an arbitrary timing by the intention of the user.

Other objects and effects of the present invention will be easily understood by those skilled in the art by referring to the following description of the specification.

[0009]

In order to achieve the above object, the present invention focuses on the input device for a personal computer, which is generally indispensable for using the personal computer, and incorporates a radio timepiece into itself. I was conceived of a new configuration As such an input device for a personal computer, the essentiality for a personal computer, a size suitable for moving to a place where reception is good,
Considering portability, the PC mouse is considered to be the most suitable. However, considering the purpose of a personal computer user such as a graphic designer or a tracer, the necessity can be understood more broadly, and in that case, other factors such as personal computer tablets and personal computer trackballs can be understood. The present invention could be extended to a personal computer input device.

More generally, the input device for a personal computer of the present invention comprises input means for generating input information according to an input operation on an operation section (for example, a left / right operation button on a mouse, a movement search mechanism, etc.), The first transmission data generating means for generating transmission data corresponding to the input information generated by the input means, and the given transmission data by USB
It is assumed to have a USB communication means for transmitting to the personal computer side according to the communication procedure. That is, the input information generated by the normal operation is transmitted to the personal computer side by the USB procedure.

A radio clock means is built in the input device for a personal computer. This radio clock means has a clock function for generating time information based on a built-in clock, and a time correction function for intermittently correcting the time information generated by the clock function based on JJY radio waves. That is, the corrected time information is incremented by the internal clock until the next correction, so that the correct current time is always held.

The personal computer input device further includes second transmission data generating means. The second transmission data generating means generates transmission data corresponding to the current time information generated by the radio-controlled timepiece means for time adjustment of the personal computer built-in clock when a predetermined transmission condition is satisfied. To do. That is, if certain transmission conditions are met,
The current time information held at that time is immediately transmitted to the personal computer side via the normal USB communication means for transmitting input information.

On the side of the personal computer, if the current time information is transmitted, the time of the built-in clock may be corrected by using the received current time information by interrupt processing.

Since the input device for a personal computer according to the present invention is configured as described above, the time of the clock incorporated in the personal computer can be set at any time without attaching a special accessory device to the connector of the personal computer or connecting the personal computer to the network. It can be corrected to the correct time.

In the device of the present invention, "predetermined transmission condition"
May be defined as the elapse of a predetermined transmission cycle or the arrival of a predetermined transmission time. With such a configuration, it is possible to correct the time of the personal computer built-in clock every time a predetermined transmission cycle elapses or when a predetermined transmission time arrives.

In the device of the present invention, "predetermined transmission condition"
May be defined as that a predetermined time transmission request is detected via the input information generated by the input operation of the operation unit. With such a configuration, the time of the personal computer built-in clock can be corrected every time a predetermined operation (generally, an operation that cannot be normally used) is performed on the operation unit.

In the device of the present invention, a battery functioning as a power source for supplying power to the circuit device forming the radio-controlled timepiece means may be incorporated. According to such a configuration,
Even if the JJY radio wave reception status at the PC installation location is poor, the operation as a radio-controlled timepiece can be performed normally by disconnecting the input device from the PC and moving it to a location with good JJY radio reception status. After the use of the personal computer, it will not interfere with the time correction of the personal computer clock. At this time, if the battery can be charged from the personal computer side via the USB cable, the trouble of frequent battery replacement can be eliminated.

The apparatus of the present invention may be provided with a display section for displaying the time corresponding to the current time information generated by the radio clock means. With such a configuration, the personal computer input device itself functions as a radio-controlled timepiece device, which is convenient.

And a second transmission data generation function for generating transmission data corresponding to the current time information sent from the radio clock function realization CPU. A USB communication function for transmitting the transmission data to the personal computer side according to the USB communication procedure is incorporated.

It includes a radio-controlled timepiece function realizing CPU that realizes a radio-controlled timepiece function using a time code.

The CPU for realizing the radio clock function intermittently generates the time information based on the built-in clock and the time information generated by the time measuring function based on the time code obtained from the signal processing circuit. Time correction function to correct,

And a second transmission data generation function for generating transmission data corresponding to the current time information sent from the radio clock function realization CPU. If the USB communication function that transmits the transmission data to the personal computer side according to the USB communication procedure and the input information generated by the input function requires transmission of the current time, the CPU for realizing the radio clock function is used. On the other hand, a current time request function for issuing a current time transmission request is incorporated.

BEST MODE FOR CARRYING OUT THE INVENTION A preferred embodiment of an input device for a personal computer according to the present invention will be described in detail below with reference to the accompanying drawings.

An external view of a personal computer mouse according to the present invention is shown in FIG. As shown in the figure, the mouse 1 for a personal computer includes a body case 4, a USB cable 3 having one end coupled to the body case 4, and a USB cable 3.
And a USB plug 2 attached to the other end of the. The body case 4 includes a right side operation button 5 and a left side operation button 6

Further, on the upper surface of the case body, there is provided a time display 7 for displaying the current time generated by a radio clock means described later.

The body case 4 accommodates an electric circuit device 12 including a mouse function realizing circuit section (described later) 13 and a radio-controlled timepiece function realizing circuit section (described later) 14.

FIG. 3 is a block diagram showing the electrical configuration of a specific embodiment of the electric circuit device 12 (hereinafter referred to as the first embodiment). As shown in the figure,
The electric circuit device 12 includes a mouse function realizing circuit section 1
3 and a circuit section 14 for realizing a radio-controlled timepiece function are included.

The mouse function realizing circuit section 13 is supplied with power from a personal computer side power source (not shown) via the connection terminal block 15 and the USB cable 3 connected thereto. On the other hand, the circuit 16 for realizing the radio-controlled timepiece function is supplied with power from the battery 16. Therefore, the radio-controlled timepiece function realizing circuit section 14 operates normally even when the tip plug 2 of the USB cable 3 is removed from the personal computer, and realizes the function as the radio-controlled timepiece. The time can be displayed on the time display unit 17. In addition, since the input / output voltage conversion circuit 18 for adjusting the signal voltage is interposed in the power supply path connecting the mouse function realizing circuit unit 13 and the radio-controlled watch function realizing circuit unit 14, it is used as a radio-controlled watch CPU. The popular radio-controlled timepiece CPU 143 (the signal voltage handled by the mouse CPU 132 is different) can be used as it is, and a new development cost for the radio-controlled timepiece IC can be saved.

The mouse function realizing circuit section 13 includes a moving distance detecting circuit 131 for detecting a moving distance through a signal from a moving search mechanism (not shown), switches 133a and 133b for left and right operation buttons, and moving distance detection. Circuit 13
Mouse function realizing CPU 132 for processing signals from 1
And are included.

In the ROM of the microcomputer constituting the mouse function realizing CPU 132, as will be described in detail later, input information corresponding to signals from the left and right operation button switches 133a and 133b and the movement distance detection circuit 131 is generated. Input function (A1), a first transmission data generation function (A2) that generates transmission data corresponding to the input information generated by the input function, and current time information from the radio clock function realization CPU. When sent, the second transmission data generation function (A3) that generates transmission data corresponding thereto and the USB communication function (A4) that transmits the given transmission data to the personal computer side according to the USB communication procedure. ), And the input information generated by the input function requests transmission of the current time, the radio clock function realizing CPU System program for implementing the current time request function of generating the current time transmission request (A5) for are stored. Each of these functions (A
1) to (A5) will be described later in detail with reference to the flowchart of FIG. 7.

In the radio clock function realizing circuit section 14, a tuning circuit 141 for receiving the JJY radio wave carrying the Japanese standard time in a predetermined format, and a signal from the tuning circuit 141 are amplified and then the time code is restored. C for realizing a radio-controlled timepiece function that realizes a radio-controlled timepiece function by using a signal processing circuit 142 that performs
PU143 and are included.

In the ROM of the microcomputer constituting the radio clock function realizing CPU 143, as will be described in detail later, a time counting function (B1) for generating time information based on a built-in clock and a time counting function are used. The time correction function (B2) for intermittently correcting the time information based on the time code obtained from the signal processing circuit 142 and the current time information to the mouse function realizing CPU 132 when the "predetermined transmission condition" is satisfied. A system program for realizing the sending function (B3) is stored.

As the "predetermined transmission condition", various transmission conditions can be adopted, but in this embodiment, as will be described later, (1) a predetermined transmission cycle elapses or a predetermined transmission time comes. That (first transmission condition), and (2)
Two types of transmission conditions are adopted: a current time transmission request arrives from the mouse CPU 132 (second transmission condition). The functions (B1) to (B
3) will be described later in detail with reference to the flowchart of FIG.

FIG. 7 is a flow chart showing the processing of the mouse CPU 132, FIG. 8 is a flow chart showing the processing of the radio clock CPU 143, and FIG. 9 is a flow chart showing the interruption processing of the personal computer side CPU.

As shown in FIG. 7, the CP for this mouse
The entire processing of U132 is started by interrupt processing, for example, each time input information corresponding to signals from the left and right operation button switches 133a and 133b and the movement distance detection circuit 131 is generated. That is, although not shown in the flowchart of FIG. 7, when the mouse is moved on the mouse pad or the left and right operation buttons are appropriately pressed, a known entry process corresponding to the input function (A1) is performed. When executed, the input information corresponding to the operation content is appropriately generated and stored in the buffer area on the memory (not shown), and then the processing shown in FIG. 7 is started.

When the process shown in FIG. 7 is started, the contents of the input information previously generated are checked (step 7
01), and then it is determined whether or not the input information is “time information transmission input” (step 702). Here, "input of time information transmission" means that the operator has performed a specific operation on the mouse to indicate that he / she wants to correct the time of the internal computer clock. . As the "specific operation" performed on the mouse for such a purpose, for example, the left and right operation buttons 5,
It is preferable to select an operation that is not normally performed, such as simultaneous pressing of 6 or a drag operation while pressing simultaneously, or double-clicking of the right operating button 5 while pressing the left operating button 6.

As a result of the judgment in step 702, if it is judged that it is not “time information transmission input” (step 7
02NO), "moving distance information" generated by the input function
Is encoded according to a predetermined format for USB communication processing (step 708). That is, when the original input information of the mouse such as “moving distance information” and “operation type information of operation button” is generated by the normal operation of the mouse, the first transmission data generation function (A
2) acts to generate "coded distance information" or the like as transmission data corresponding to the input information (step 70).
8).

Thereafter, the "coded distance information" generated in the processing of step 708 is transmitted to the personal computer side CPU according to the USB communication procedure. That is, when “coded distance information” or the like is given as the transmission data corresponding to the input information, the USB communication function (A4) operates and the given “coded distance information” or the like is transferred to the USB communication procedure. Therefore, it is immediately transmitted to the CPU on the personal computer side (step 709).

On the other hand, as a result of the determination in step 702, if the input information generated by the input function (A1) is determined to be "time information transmission input" (step 70).
2YES), the time information transmission request command is issued to the radio-controlled timepiece CPU 143 (step 703), and then the CPU waits for the current time information to be returned from the radio-controlled timepiece CPU 143 (step 704N).
O).

In this state, the radio clock CPU 14
When it is confirmed that the current time information from 3 is received (YES in step 704), the time information transmission process including the encoding of the received current time information is executed, and the personal computer CPU
An interrupt request is made to (step 705) and waits until the preparation is OK on the receiving side to permit the interrupt (step 706). After that, when the interrupt is not permitted within the specified time (NO in step 706), the process ends without transmitting the time information. On the other hand, if the interrupt is permitted within the specified time (step 706YE
S), the “coded time information” generated in the process of step 705 is transmitted to the personal computer CPU in accordance with the USB communication procedure.

That is, when the input information generated by the input function requests the transmission of the current time, the current time request function (A5) operates to send the current time to the radio clock function realizing CPU. A transmission request is issued (step 703). Also, the radio clock function realizing CPU 143
When the current time information is sent from (step 7
04YES), and the second transmission data generation function (A3) operates to generate transmission data corresponding thereto (step 705). Furthermore, when the "coded time information" is given as the data for transmission, the USB communication function (A4) operates to give the given "coded time information".
Is immediately transmitted to the CPU on the personal computer side in accordance with the USB communication procedure (step 707).

Next, as shown in FIG. 8, the entire processing of the radio clock CPU is made up of the timekeeping function (B1) for generating time information based on the built-in clock and the time information generated by the timekeeping function. Time correction function (B2) for intermittently adjusting the time based on the time code obtained from the signal processing circuit 142
And a function of sending the current time information to the mouse function realizing CPU 132 when the "predetermined transmission condition" is satisfied (B
It is roughly divided into 3).

The timekeeping function (B1) is mainly realized by the clock (timekeeping) process (step 803). The time adjustment function (B2) is mainly realized by the time data reception process (step 801), the time adjustment process (step 802), and the automatic reception time arrival waiting process (step 804). The current time information transmission process (B3) is mainly realized by the transmission request arrival determination process (step 806), the transmission time arrival standby process (step 807), and the time information output process (step 808).

That is, the radio-controlled timepiece CPU shown in FIG.
When the process of (1) is started, first, the time data receiving process (step 801) is executed to acquire the time data restored from the JJY radio wave, and then the time adjusting process (step 802) is executed. Based on the acquired time data, the time information generated by the clock (timekeeping) means described later is corrected. In the subsequent clock (timekeeping) process (step 803), a process of generating time information based on the built-in clock is executed. In this process, the time information corrected in the time correction process (step 802) is used as a reference, and the elapsed time information obtained by counting the built-in clock is added thereto, whereby the time information is sequentially obtained. The process of stepping forward to generate the current time information is executed.

Thereafter, the arrival of the automatic reception time is awaited (step 804 NO), and every time the arrival of the automatic reception time is confirmed (step 804 YES), a new time data reception process (step 801) is performed, and the time is adjusted accordingly. The time information generated by the process (step 802) and the clock (timekeeping) process (step 803) is JJY.
It is corrected intermittently based on the radio wave. The current time information thus generated is appropriately displayed on the time display 7 (17) by executing the time display process (step 805). As a result, the mouse itself functions as a radio-controlled timepiece device.

On the other hand, the radio clock CPU 143 continuously monitors the establishment of the "predetermined transmission condition" while executing the clock (clocking) process (step 803).
Here, as the "predetermined transmission condition", (1) the arrival of the current time information transmission request from the mouse CPU 132, (2) the arrival of a predetermined transmission time,
2 conditions are defined. That is, in the radio clock CPU 143, the presence or absence of the current time information transmission request from the mouse CPU 132 at a proper timing while executing the clock (timekeeping) process (step 803) and the predetermined time. Whether or not the transmission time has arrived (step 807) is monitored. In this state, if it is determined that there is a transmission request (YES in step 806) or the transmission time has arrived (YES in step 807), the time information transmission process (step 808) is subsequently executed, and the clock (clock) process (step 803) is executed. The current time information generated in () is transmitted to the mouse CPU 132.

As described above with reference to the flowchart of FIG. 7, there is a transmission request (YES in step 806).
The current time information transmitted subsequently to is passed to the time information transmission processing (step 705) via the time information reception determination (step 704 YES). The current time information transmitted after the arrival of the transmission time (step 807) is carried over from the start point (step 710) to the time information transmission process (step 705) in the interrupt process.

In this way, the mouse CPU 132 and the radio clock CPU 142 cooperate with each other so that a predetermined transmission request operation is performed each time a fixed transmission cycle elapses or a predetermined transmission time arrives. Each time, the time information measured by the radio clock is transmitted from the mouse side to the personal computer side, and by using this time information, the time of the personal computer built-in clock can be adjusted.

The time adjustment processing of the built-in clock in the CPU of the personal computer is executed by the interruption processing together with the distance information correspondence processing corresponding to the normal mouse operation. FIG. 9 is a flowchart showing the interrupt processing of the personal computer side CPU.

In the figure, when the processing is started, first, the content of the received data coming from the mouse is checked (step 901). If it is determined that the received data is not "time information" (NO in step 902),
The coded distance information processing (step 905) is executed. In this coded distance information processing (step 905), processing corresponding to the XY movement distance of the mouse and the operation content of the operation button (for example, update processing of the cursor position on the screen) is executed.

On the other hand, the received data is "time information".
If YES is determined (YES in step 902), the internal clock time correction process (step 903) is executed,
The time of the personal computer built-in clock is corrected according to the accuracy of the radio clock, and the corrected time of the internal clock is displayed on the screen of the personal computer (step 904).

According to the above-mentioned personal computer mouse device, U
Just by connecting to the personal computer via the SB plug, the accurate time information generated by the built-in radio clock is sent to the personal computer via the USB cable periodically or by a predetermined button operation. Even if you don't have a built-in radio clock, connect a special accessory such as a GPS receiver to your PC, or connect your PC to another PC via a network, It becomes possible to easily correct according to the time accuracy. In addition, the mouse device for the personal computer has a built-in battery that guarantees the operation of the radio-controlled timepiece, so even if the JJY radio wave reception condition at the computer installation location is poor, the mouse device itself has a USB plug. If you take it off and carry it to a place where the reception of JJY radio waves is good, you can correct the time on the computer's built-in clock with the time accuracy according to the time correction status up to that point when using the PC. it can. Further, according to the mouse for a personal computer of the present invention, the time of the internal clock of the personal computer can be adjusted just by connecting it to the personal computer via the USB cable, so that even if there are a plurality of personal computers, one mouse can be used. You can easily adjust the time of those built-in clocks simply by connecting the mouse to each computer in sequence.
You can adjust the time on many PCs at no extra cost.

In the above embodiment, the non-rechargeable primary battery 1 is used as the battery for the radio-controlled timepiece backup.
6, the secondary battery 16a is adopted as shown in FIG. 4, and the secondary battery 16a is floated through the charging circuit 19 and the diode 20 by the personal computer side power supplied by the USB cable 3. You may make it charge. With such a configuration, it is possible to save the trouble of frequent battery replacement.

Further, in the above embodiment, in order to save the labor and cost of developing a new CPU, the existing radio-controlled timepiece CPU 143 is provided by interposing the input / output voltage conversion circuit 18.
Also, the existing mouse CPU 132 is used. However, if the development cost allows, as shown in FIGS. 5 and 6, the functions of these two CPUs 143 and 132 are combined into one integrated CPU 21. May be realized.
Here, FIG. 3 and FIG. 5 correspond, and FIG. 4 and FIG. 6 correspond. In such a case, the integrated CPU 21 will substantially incorporate both of the processes shown in the flowcharts of FIGS. 7 and 8.

Furthermore, although the present invention is applied to the mouse for a personal computer in the above embodiment, the present invention is not limited to this.
It is widely applicable to personal computer input devices such as personal computer tablets and personal computer trackballs.

Incidentally, an example in which the present invention is applied to a tablet for a personal computer is shown in FIG. In the figure, 2 is a USB plug, 3 is a USB cable, 7 is a time display,

In this example, it is generated by the built-in radio clock of the case body 9 in response to a specific operation of the operation pen 10 and the pen button 10a on the drawing operation pad unit 11 or each time the set time of the timer elapses. The time information is sent to the personal computer side.

Since the configuration of sending in is adopted, the time of the internal clock of the personal computer can be set without installing a radio clock in the personal computer itself, attaching a special accessory device such as a GPS receiver to the connector of the personal computer, or connecting the personal computer to the network. Can be adjusted to the correct time at any time.

Further, according to the present invention, it is possible to correct the time of the personal computer built-in clock to an accurate time at any timing controlled by time or by the user's will.
