Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information processing apparatus such as a personal computer equipped with a jog shuttle, and more specifically, information processing capable of scrolling a display screen in an arbitrary direction by the jog shuttle. It relates to the device.

[0002]

2. Description of the Related Art Generally, documents and figures are created using writing instruments such as pencils and paper, but in recent years, due to their high correction efficiency and editing efficiency, computer calculations and storage have been made. In many cases, it is created using an information processing device such as a personal computer or a document processing device capable of displaying and editing character data and graphic data under control.

By the way, the size of the created document or figure is often larger than the size that can be displayed on the display screen. Therefore, in general, the information processing apparatus can scroll the display screen in any direction of up and down direction and left and right direction in order to easily grasp the entire document or figure. Scrolling is done by key input and mouse input.

The scrolling by the above-mentioned key input is performed by assigning scroll instruction data to specific keys on the keyboard and pressing these specific keys. The content of the instruction data includes a scroll unit, a scroll direction, and a scroll speed, and the method of designating these instruction data is set as shown in Table 1, for example.

[0005]

[Table 1]

Further, scrolling by mouse input is performed by assigning scroll instruction data on the screen using a graphical user interface and designating a mouse cursor when a mouse button is pressed.

That is, as shown in FIG. 9, a display screen 51 for displaying character data and the like and a scroll bar 52 which is a bar-shaped graphical image are displayed on the screen of the information processing apparatus.
52 and are displayed. And scroll bar 52.5
The scroll direction of the display screen 51 is set by moving the mouse cursor 53 to the second scroll box 52a / 52a and pressing the mouse button to scroll the designated scroll box 52a / 52a in the arrow direction. ing. The scroll speed and the scroll unit of the display screen 51 are set to be proportional to the moving speed and the moving unit of the scroll boxes 52a and 52a.

[0008]

However, in the above-described conventional information processing apparatus, the pressing direction of the pressing work of the key or the mouse button, which is the work required for scrolling the display screen 51, is the scroll direction of the display screen 51. There is a problem that it has nothing to do with. Therefore, in the conventional information processing device, the above-mentioned pressing work is not intuitively associated with scrolling, so that it becomes difficult for a user unfamiliar with the operation of the information processing device to intuitively recognize the operation method during scrolling. At the same time, even a user who is accustomed to the operation will feel a sense of discomfort during scrolling when performing continuous operations.

Therefore, it is an object of the present invention to provide an information processing apparatus capable of sensuously connecting a scrolling operation method and scrolling.

[0010]

In order to solve the above problems, an information processing apparatus of the present invention is capable of scrolling a display screen in any scroll direction and scroll speed, and has the following features. There is.

That is, the information processing apparatus is characterized by having a jog shuttle for scrolling the display screen in accordance with the rotating state of the jog dial.

[0012]

According to the above construction, the information processing apparatus can set the scroll direction and scroll speed of the display screen in correspondence with the rotating state of the jog dial. At this time, since the sensation of rotating the jog dial matches the sensation of scrolling the display screen as a scroll, the information processing device with this jog shuttle intuitively understands the operation method during scrolling, even for users unfamiliar with the operation. It is possible for the user to be made aware of it, and even a user who is accustomed to the operation does not feel uncomfortable when scrolling when performing the operation continuously.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The following will describe one embodiment of the present invention with reference to FIGS.

The information processing apparatus according to this embodiment includes a CRT (Cathode-RayTube) for outputting character data, a keyboard used for inputting display data such as character data and instruction data, and a floppy disk drive for recording the display data. It has a recording unit such as a printer, a printer capable of printing created documents, figures, and tables, and a control unit for controlling each of these devices.

The keyboard described above, as shown in FIG.
It has a jog shuttle 1. This jog shuttle 1
Is a rotatable jog dial 2 having a recess 2a formed therein.
A rotary member 3 that is in contact with the side peripheral surface of the jog dial 2; and a jog dial detection unit 4 that detects the rotational direction and rotational speed of the jog dial 2 based on the rotational direction and rotational speed of the rotary member 3. Have The jog dial detecting section 4 is connected to the jog dial controller 6 and outputs n-bit rotational speed data and 1-bit rotational direction data to the jog dial controller 6.

The jog dial controller 6 described above is
JWC port 7a that outputs the command signal JWC to obtain the rotation speed data of the jog dial 2, JWD port 7b that outputs the rotation speed data of the jog dial 2, and a command signal to obtain the rotation direction data of the jog dial 2.
JRC port 7c that outputs JRC and JRD port 7d that outputs rotation direction data of jog dial 2
Is connected to a CPU (Central Processing Unit) 5 via a jog dial controller 6, and the jog dial controller 6 controls the rotation direction data and the rotation speed data input from the jog dial detection unit 4 by using the ports 7a, 7b, 7c, 7d. It is designed to be output to the CPU 5 of the unit.

As shown in FIG. 7, the CPU 5 has a ROM (Read Only Memory) and an RA constituting a control unit.
It is connected to a memory 8 composed of M (Random Access Memory). A display data area 8a for storing display data and a VRAM area 8b are formed in the RAM of the memory 8, and the display data stored in the VRAM area 8b is displayed on the CRT 10 via the CRT controller 9. Is becoming

Further, the ROM of the memory 8 stores various programs such as a scroll routine, a rotation direction detection routine, a rotation speed detection routine, a scroll direction routine, and a scroll speed routine. By transferring the display data in the area 8a to the VRAM area 8b in accordance with the rotation direction, rotation speed, and rotation interval of the jog dial 2, the CR data is transferred.
The display of T10 is scrolled in an arbitrary scroll direction and scroll speed.

The relationship between the rotation direction, the rotation speed, and the rotation interval of the jog dial 2 and the scroll direction and the scroll speed are set as shown in Table 2.

[0020]

[Table 2]

That is, the scrolling speed in the vertical direction is 1
Since it corresponds to the feeling of referring to the contents of a piece of infinitely long paper while winding it like a scroll, the jog dial 2 is executed by rotating the jog dial 2 at a normal speed for winding the scroll. Further, the low-speed scrolling in the left-right direction corresponds to the feeling of referring to the content while reading it carefully, and is therefore executed by rotating the jog dial 2 at a low speed like a "knob".

Further, high-speed scrolling in the up-down direction and the left-right direction corresponds to the feeling of following a scroll, and is therefore executed by rotating the jog dial 2 at high speed. At this time, the distinction between the up-down direction and the left-right direction for high-speed scrolling is, for example, when scrolling rightward and reaching the right end, scroll up one line and then scroll down from the left end to right. Corresponds to the sensation at the time of reference, it is determined that the jog dial 2 is scrolling in the left-right direction when the jog dial 2 is intermittently rotated at a high speed.
Is continuously scrolled at a high speed, it is determined that the scroll is a vertical scroll.

The operation of scrolling the information processing apparatus with the jog dial 2 in the above configuration will be described.

First, when the display data is input through a keyboard (not shown) or the like, the display data will be stored in the display data area 8a of the memory 8 as shown in FIG. Part of the data stored in the area 8a is transferred to the VRAM area 8b of the memory 8. The display data of the VRAM area 8b is CR
It is displayed on the CRT 10 via the T controller 9, and a document, a figure, etc. are created while looking at the display screen of the CRT 10.

Next, when the display screen of the CRT 10 is scrolled, a specific key on the keyboard to which scroll instruction data is assigned is pressed, or the jog shuttle 1 is used as shown in FIG. become. When the jog shuttle 1 is used for scrolling, the jog dial 2 is rotated, and the rotation state including the rotation direction, rotation speed, and rotation interval of the jog dial 2 is determined by the scroll routine of FIG. 1 to determine the scroll speed and scroll direction. Will be converted to.

That is, when the jog dial 2 is rotated,
The rotating state of the jog dial 2 is transmitted to the jog dial detecting section 4 via the rotating member 3 and is detected by the jog dial detecting section 4, and thereafter, as the jog dial controller 6 as n-bit rotational speed data and 1-bit rotational direction data. Will be output to.

At this time, the rotation direction detection routine of FIG. 2 is executed to detect the rotation direction of the jog dial 2, and the command signal JRC for obtaining the rotation direction data of the jog dial 2 from the CPU 5 causes the JRC port 7c to be output. Is output to the jog dial controller 6 via (S
21). The rotation direction data input to the jog dial controller 6 is output to the CPU 5 via the JRD port 7d when the jog dial controller 6 receives the command signal JRC, and is taken into the CPU 5 (S22). As a result, the CPU 5 detects the rotation direction of the jog dial 2 based on the rotation direction data as shown in FIG. 1 (S1).

When the leftward rotation direction is detected in S1, the rotation speed of the jog dial 2 is detected in S.
On the other hand, when the rotation direction to the right is detected while S2 is executed, S3 which similarly detects the rotation speed of the jog dial 2 is executed. S2 or S above
3 is executed, the rotation speed detection routine of FIG. 3 is executed, and as shown in FIG. 6, the command signal JWC for obtaining the rotation speed data of the jog dial 2 is JWC.
It is output to the jog dial controller 6 via the port 7a (S23). Then, the rotation speed data input to the jog dial controller 6 is output to the CPU 5 via the JWD port 7b when the jog dial controller 6 receives the command signal JWC, and is taken into the CPU 5 (S24).
As a result, the CPU 5 detects the rotation speed of the jog dial 2 based on the rotation speed data as shown in FIG. 1 (S2 and S3).

When it is determined that the rotation speed of the jog dial 2 is "low" by executing S2 executed when the rotation speed of the jog dial 2 is leftward, the display screen is scrolled to the left at a low speed. That means (S
4) If it is determined that the rotation speed of the jog dial 2 is "normal", the display screen is scrolled downward at a low speed (S5).

At this time, the operation when the display screen scrolls downward at a low speed will be described. By executing the scroll direction routine of FIG. 4, as shown in FIG.
The display data stored in the RAM area 8b is moved in the D direction (S25), and the area O outside the VRAM area 8b is moved.
The display data existing in (d, l) will be removed. In the area O (d, l), d indicates a row on the display screen and l indicates a column on the display screen (S26). Then, the area E (d,
The new display data is transferred from the display data area 8a to l), so that the display screen is scrolled downward (S27). In addition, the scroll speed is set by the execution of the scroll speed routine of FIG. 5 in the column (l) corresponding to the rotation speed of the jog dial 2, and the scroll width is changed to change the scroll speed. Will be changed (S2
8).

Next, as shown in FIG. 1, when it is determined that the rotation speed of the jog dial 2 is "high speed", it is determined whether the jog dial 2 has stopped within a predetermined time based on the rotation speed data. It will be determined (S8). Then, when it is determined that the rotation is stopped within a predetermined time and the rotation is intermittent, the scroll is performed to the left at high speed (S9). On the other hand, when it is determined that the rotation is continuously performed without stopping within the predetermined time, the scroll is performed downward at high speed (S10).

On the other hand, when it is determined that the rotation speed of the jog dial 2 is "low speed" by executing S3 which is executed when the rotation direction of the jog dial 2 is right direction, the display screen moves to the right direction at low speed. Will be scrolled (S6), the rotation speed of the jog dial 2 is "normal"
If it is determined that, the display screen is scrolled upward at a low speed (S7).

Further, when it is determined that the rotation speed of the jog dial 2 is "high speed", it is determined whether or not the jog dial 2 has stopped within a predetermined time based on the rotation speed data (S11). ). Then, when it is determined that the rotation is stopped within a predetermined time and the rotation is intermittent,
It will scroll to the right at high speed (S1
2). On the other hand, if it is determined that the motor is continuously rotating without stopping within the predetermined time, the scroll is performed downward at high speed (S13).

As described above, the information processing apparatus of this embodiment is
The scroll direction and scroll speed of the display screen can be set according to the rotating state of the jog dial 2. Further, in the information processing apparatus, since the feeling of rotating the jog dial 2 matches the feeling of scrolling the display screen as a scroll, even a user unfamiliar with the operation of the information processing apparatus can intuitively recognize the operation method during scrolling. In addition, even if the user is accustomed to the operation, the user does not feel uncomfortable when scrolling when continuously performing the operation.

In the information processing apparatus of this embodiment, the jog dial 2 of the jog shuttle 1 is provided on the keyboard of the information processing apparatus, but the invention is not limited to this, and the jog dial 2 and the keyboard are separated. The keyboard and the jog dial 2 may be detachably attached. In this case, a keyboard can be attached when used for data input, and the jog dial 2 can be attached to the information processing device instead of the keyboard when used for data reference. Therefore, it is possible to further reduce the weight of the information processing device particularly suitable for carrying.
