Description

  The present invention includes a display unit having a scrollable display screen, a scroll operation unit configured to perform a scroll operation so as to scroll the display screen, and a signal output by the scroll operation. The present invention relates to a scroll speed control system and a program including control means for controlling scroll based on a signal.

  Examples of the scroll operation means include a mouse with a wheel, and the mouse with a wheel is configured such that the wheel is rotated by a finger and the scroll speed of the display screen follows the rotation speed of the rotated wheel. Yes. However, when there are many pages to be displayed on the display screen, not only the wheel has to be rotated for a long time, but also there is a limit to increasing the scrolling speed. It was unsuitable.

  Therefore, a switching device that can automatically scroll the display screen at a speed faster than the maximum speed in the normal rotation mode by switching the rotation mode for scrolling the display screen from the normal rotation mode to the high-speed rotation mode is proposed. Has been. This switching device is provided in a mouse with a wheel, and switches from the normal rotation mode to the high-speed rotation mode when it is detected that the wheel is pushed down. The switching device includes a contact bar that moves downward in contact with a wheel that is operated to be depressed, a lever that moves downward in conjunction with the contact bar, and a switch that is pushed down by the lever. When the wheel is pushed down, it is possible to detect that the wheel is pushed down by causing the contact bar to press the switch portion through the lever portion (see, for example, Patent Document 1).

Utility Model Registration No. 3146387

  According to the configuration of the above-mentioned Patent Document 1, since the installation space for arranging a large number of members such as a contact bar, a lever part, and a switch part constituting the switching device must be secured in the mouse, the mouse is large. There was an inconvenience.

  In addition, since it is configured to be switched to the high-speed rotation mode by pushing down the wheel, there is only one condition for switching to the high-speed rotation mode, and there is a disadvantage that it is difficult for the user to use.

  In view of the above-described situation, the present invention intends to provide a scroll speed control system and program that not only can avoid an increase in the size of the scroll operation means, but also is excellent in terms of use. Let it be an issue.

  In order to solve the above-described problems, the scroll speed control system of the present invention is configured to include a display means having a scrollable display screen and a scroll operation for scrolling the display screen, and a signal is output by the scroll operation. A scroll speed control system comprising: a scroll operation means to be controlled; and a control means for controlling the scroll based on a signal from the scroll operation means, wherein the control means is output from the scroll operation means. A signal number discriminating means for discriminating whether or not the number of signals included in the signal group composed of signals is equal to or greater than the set number of set signals, and the signal number discriminating means sets the number of signals from the scroll operation means If it is determined that the number is less than the number of signals, the display screen is scrolled at a speed based on the signals included in the signal group. If it is determined that the number of signals is equal to or greater than the set number of signals, forced scroll execution means for scrolling the display screen at a preset speed regardless of the signal from the scroll operation means, and the setting signal number is changed. And a signal number setting change means.

  The computer-executable program according to the present invention includes a display unit having a scrollable display screen, a scroll operation for scrolling the display screen, and a signal that is output by the scroll operation. And a computer-executable program comprising control means for controlling scrolling based on a signal from the scroll operation means, wherein the computer is constituted by a signal output from the scroll operation means. A signal number discriminating means for discriminating whether or not the number of signals included in the signal group is equal to or greater than a set number of set signals, and the number of signals from the scroll operation means by the signal number discriminating means being less than the set signal number If it is determined that there is, scroll the display screen at a speed based on the signals included in the signal group, If it is determined that the number of signals is equal to or greater than the predetermined number of signals, forced scroll execution means for scrolling the display screen at a preset speed regardless of the signal from the scroll operation means, and the setting signal number is changed. It may be a program characterized by functioning as a signal number setting change means for this purpose.

  According to the configuration of the present invention, the scroll operation means is determined by determining whether or not the number of signals included in the signal group composed of signals output from the scroll operation means is equal to or greater than the set number of set signals. For example, a situation in which the scroll operation means is operated at a high speed in order to increase the scroll speed for scrolling the display screen. Regardless of the signal, the scroll speed is changed to a set speed (for example, high speed) to scroll the display screen. By scrolling in this way, the display screen can be scrolled at high speed in a short time even when the number of pages is large. When it is determined that the number of signals from the scroll operation means is less than the set number of signals, the display screen is scrolled at a speed based on the signals included in the signal group. Further, by changing the setting signal number, it is possible to change the condition for executing the forced scroll execution means in accordance with the individual operation situation. The scroll speed can be set to be higher than the normal scroll speed, or can be set to be lower than the normal scroll speed.

  In the computer-executable program of the present invention, the scroll operation means is a mouse with a wheel, and the computer outputs a signal output by rotating the wheel of the mouse with the signal. Whether or not the rotational speed indexed by the rotational speed indexing means is equal to or higher than the set rotational speed. When the determined rotation speed of the wheel is determined to be equal to or higher than the set rotation speed, the forced scroll execution means may be executed.

Whether or not the rotational speed indexed by the rotational speed indexing means is equal to or higher than the set rotational speed. When the wheel rotation speed is determined to be equal to or higher than the set rotation speed, one signal group is counted, and the wheel rotation speed is equal to or higher than the set rotation speed from the number of signals included in the next signal group. If the wheel rotation speed is determined to be greater than or equal to the set rotation speed, the next signal group is counted and the total count is If it is a constant number of times or more, may be functions is allowed to perform the forced scrolling execution means.

Can be avoided. In addition, by changing the number of signals set by the signal number setting change means, the condition (switching condition) for executing the forced scroll execution means can be changed in accordance with the individual operation situation, and the scroll speed that is excellent in terms of use A control system and program can be provided.

It is the schematic of a scroll speed control system. (A) is explanatory drawing which shows the output signal from a mouse | mouth, (b) is explanatory drawing which shows an input signal when a computer receives and recognizes the output signal from a mouse | mouth. It is a block block diagram of a control means. It is a display screen on which mouse properties are displayed. It is a flowchart which shows scroll speed control. It is a flowchart which shows other (2nd) scroll speed control.

  Hereinafter, an embodiment of a scroll speed control system according to the present invention will be described with reference to the drawings.

  As shown in FIG. 1, the scroll speed control system is configured by a desktop personal computer (hereinafter referred to as a computer) which may be a laptop computer such as a notebook computer, and the computer has a scrollable display screen 1A. The display means 1 having the above-described structure, the scroll operation means 2 configured to be able to perform a scroll operation so as to scroll the display screen 1A, and a scroll based on a signal from the scroll operation means 2 And a control means 3 for controlling the speed.

  The display means 1 includes a monitor having a display screen 1A capable of displaying characters, figures, images, etc., and the display screen 1A is configured to be scrollable in the vertical (vertical) direction and the horizontal (horizontal) direction. ing.

  The scroll operation means 2 comprises a mouse with a wheel. The mouse 2 with a wheel includes a mouse main body 2A and a wheel 2B that is rotatably mounted around the horizontal axis X at the left and right center of the tip of the mouse main body 2A. The wheel 2B can be scrolled by rotating the wheel 2B to the front side or the back side with a finger, and a signal corresponding to the scroll operation is output.

  In addition, the mouse 2 with a wheel is configured so that the wheel 2B can be rotated by a predetermined angle (for example, 15 degrees). When the wheel 2B is rotated with a time interval, the wheel 2B is intermittent each time the predetermined angle is rotated. If a signal is output continuously and the wheel 2B is continuously rotated without leaving time, a continuous signal will be output side by side. Specifically, as shown in FIG. 2 (a), after the wheel 2B rotates 15 degrees from the left end of the figure, the wheel 2B rotates 30 degrees continuously with a time interval, and further 45 degrees with a time interval. After rotating, the wheel 2B rotates 15 degrees with a time interval, and further, after the wheel 2B rotates 15 degrees with an interval of time T or more, it rotates 45 degrees continuously with a time interval. It shows a signal output when it rotates 15 degrees and further rotates 30 degrees continuously with a time interval.

  The control means 3 is provided in a processing device 4 for executing a program or controlling the activation of hardware. In addition to the control means 3, various programs such as an e-mail program, a printer (not shown) control program, and an OS (Operating System) are installed in the computer and cooperate with the computer hardware. Each program can be executed.

  Further, as shown in FIG. 3, the control means 3 is included in a signal group including a receiving means R for receiving an output signal from the wheeled mouse 2 and a signal output from the wheeled mouse 2. Signal number determining means 5 for determining whether or not the number of signals to be set is equal to or greater than the set number of set signals, and the number of signals from the wheeled mouse 2 by the signal number determining means 5 being less than the set number of signals. When determined, the normal scroll execution means 6 for scrolling the display screen 1A at a preset normal scroll speed, and the signal number determination means 5 causes the number of signals from the mouse 2 with a wheel to be equal to or greater than the set number of signals. 1A, the scroll speed is set at a set speed faster than the normal scroll speed regardless of the signal from the mouse 2 with a wheel. The forced scrolling execution unit 7 to scroll, and a signal number setting changing means 8 for setting changes the number the setting signal.

  The receiving means R is configured to receive a signal from the mouse 2 with a wheel and to divide the received signal into a signal group and determine that the signal is a signal when operated within one action. Yes. That is, when the signal shown in FIG. 2A is received, the time (interval) from the signal output by the rotation of the wheel 2B to the signal output by the next rotation of the wheel 2B is less than the set time T. Is determined to be a signal when the mouse 2 with a wheel is operated by one action, and these signals are grouped together (one signal group) and stored in a stack (memory). Based on the number of signals of the group, a rotation speed, a rotation amount, and the like of the wheel 2B described later can be calculated. FIG. 2B shows a case where 14 signals are output in total, and it is determined that 7 signals are operated by one action, with an interval of time T or more. Yes.

  The number-of-signals discriminating means 5 is based on the number of signals included in a signal group composed of signals output by rotating the wheel 2B of the mouse 2 with a wheel, and the number of signals operated by one action described above. Rotation speed calculation means 9 for calculating the rotation speed, the number of signals included in the signal group composed of signals output by rotating the wheel 2B of the mouse 2 with a wheel, and the signal operated by one action described above When the rotation amount calculation means 10 for calculating the rotation amount of the wheel 2B from the number and the rotation amount of the wheel 2B is equal to or greater than the set rotation amount and the rotation speed of the wheel 2B is determined to be equal to or greater than the set rotation speed In addition, the signal group is counted (incremented) by one, and the rotation amount of the wheel 2B is set from the number of signals included in the next signal group. It is determined whether or not the rotation speed is equal to or greater than the amount and the rotation speed is equal to or greater than the set rotation speed, and it is determined that the rotation amount of the wheel 2B is equal to or greater than the set rotation amount and the rotation speed is equal to or greater than the set rotation speed. In this case, the next signal group is counted (incremented) by one, and when the total count is equal to or greater than the set number, the number of operations is detected as the number of operations in which the wheel 2B is operated rapidly. And.

  The rotation speed calculation means 9 calculates the rotation speed of the wheel 2B as the number of signals / 1 action time (for example, set to 11 msec) = 7/11 = 0.63 (number of signals / msec). For example, if the set rotation speed is set to 0.5 (number of signals / msec), the rotation speed calculation means 9 determines that the rotation speed of the wheel 2B is equal to or higher than the set rotation speed.

  As described above, when the number of signals is output in one action, the rotation amount calculation means 10 sets the rotation amount of the wheel 2B to 7 × 120 (the rotation amount for one signal is 120) = Calculated as 840. For example, if the set rotation amount is set to 480, the rotation amount calculation means 10 determines that the rotation amount of the wheel 2B is equal to or greater than the set rotation amount.

  When the operation number detection means 11 determines that the rotation amount of the wheel 2B is equal to or greater than the set rotation amount and the rotation speed of the wheel 2B is equal to or greater than the set rotation speed, the wheel 2B is operated rapidly. The number of operations is counted (incremented) by one, and the rotation amount of the wheel 2B is equal to or greater than the set rotation amount within a predetermined time (for example, more than 100 msec and 500 msec) from that point, and the rotation speed of the wheel 2B is the set rotation speed. When it is determined whether or not it is equal to or greater than the set rotation amount and equal to or greater than the set rotation speed, the number of times that the wheel 2B has been operated rapidly is further counted by 1 (increment). If the total number of counts (in this case, twice) is determined to be greater than or equal to the set number of times (for example, set to 2) In, it is determined that the wheel 2B is abruptly operated operation number set number of times or more.

  The normal scroll execution means 6 determines that the number of signals from the wheeled mouse 2 is less than the set number of signals by the signal number determination means 5, that is, the rotation amount of the wheel 2B is less than the set rotation amount. If the rotation amount of the wheel 2B is determined to be less than the set rotation speed even if the rotation amount of the wheel 2B is equal to or greater than the set rotation amount, or the rotation amount of the wheel 2B is equal to or greater than the set rotation amount. In addition, even if the rotation speed of the wheel 2B is equal to or higher than the set rotation speed, when it is determined that the number of times that the wheel 2B has been operated rapidly is less than the set number of times, the display is performed at a preset normal scroll speed. Scroll the screen 1A.

  The forced scroll execution means 7 determines that the scroll speed is independent of the signal from the wheeled mouse 2 when the signal number determining means 5 determines that the number of signals from the wheeled mouse 2 is equal to or greater than the set number of signals. Is changed to a set speed faster than the normal scroll speed to scroll the display screen 1A. That is, it is determined that the rotation speed of the wheel 2B is equal to or higher than the set rotation speed, the rotation amount of the wheel 2B is determined to be equal to or higher than the set rotation amount, and the number of times that the wheel 2B is operated rapidly is set. If it is determined that the number is greater than or equal to the number of times, the forced scroll execution means 7 is executed to scroll the display screen 1A at a set speed faster than the normal scroll speed.

  The signal number setting changing means 8 sets the threshold value (setting value) of the rotation speed calculating means 9, the threshold value (setting value) of the rotation amount calculating means 10, and the threshold value (setting value) of the operation frequency detecting means 11. It is a means that can be set. Specifically, as shown in FIG. 4, the properties of the wheeled mouse 2 are displayed on the display screen. When the property is displayed, the setting rotational speed of the wheel 2B can be changed by moving the slider 15 that changes the rotational speed of the wheel 2B to the left and right using the mouse 2 with a wheel. The set rotational speed is set to a slower speed as the slider 15 is moved to the left side, and the set rotational speed is set to a higher speed as the slider 15 is moved to the right side. Moreover, the setting rotation amount of the wheel 2B can be set and changed by moving the slider 16 that changes the rotation amount of the wheel 2B to the left and right using the mouse 2 with a wheel. As the slider 16 is moved to the left side, the rotation amount is set to a smaller rotation amount, and as the slider 16 is moved to the right side, the rotation amount is set to a larger rotation amount. In addition, by changing the number of rotations of the display unit 14 using the mouse 2 with a wheel, it is possible to set and change the number of operations (set number of times) in which the wheel 2B is operated. Although it is 2 in the figure, it may be set to 3 or more.

  Furthermore, the control means 3 is provided with scroll speed setting changing means 101. The speed at which the display screen is scrolled in the vertical direction (vertical direction) can be set by moving the slider 12 that changes the scroll speed of the high-speed scroll on the display screen in FIG. 4 to the left and right. The scroll speed becomes faster as the slider 12 is moved to the right side, and the scroll speed becomes slower as the slider 12 is moved to the left side. Note that the minimum speed set by moving the slider 12 to the left end can be set to a speed that is faster than the maximum speed of the normal scroll speed, or can be set to the same speed as the maximum speed of the normal scroll speed or a slightly slower speed. . In this way, various properties related to mouse operations can be changed at once by opening the mouse properties.

  Next, scroll speed control will be described based on the flowchart of FIG. When receiving means R receives a signal from mouse 2 with a wheel (step S1), whether or not the time interval with the previous input signal from mouse 2 with a wheel is within T (for example, set to 100 msec). (Step S2), if it is within T, it is recognized as a signal in the same action (one action) as the previous input signal, and these signals are collectively stored as a signal group in a stack (memory). (Step S3). Subsequently, it is determined whether or not the received signal ignore flag is OFF (step S4). The reception signal ignorance flag is a flag provided for ignoring the signal from the mouse 2 with the wheel once when the number of reception signals in one action reaches the set rotation amount Rmin. .

  When the received signal ignore flag is OFF, the rotation amount calculation means 10 calculates the total rotation amount from the total number of signals of one action stored in the stack, and the calculated total rotation amount is the set rotation amount Rmin. It is determined whether or not this is the case (step S5). If it is determined that the total rotation amount of one action is greater than or equal to the set rotation amount Rmin, the received signal ignore flag is turned ON (step S6), and the subsequent signals from the mouse 2 with a wheel are ignored and not captured. After entering the state, the process proceeds to the next judgment.

  Next, the rotation speed calculation means 9 calculates the rotation speed of the wheel 2B from the total number of signals of one action stored in the stack, and determines whether or not the calculated rotation speed is equal to or higher than the set rotation speed Vc. (Step S7). When it is determined that the rotational speed of the received signal within one action is equal to or higher than the set rotational speed Vc, the operation number detection means 11 increments the rotational speed count by 1 (step S8), and then the rotational speed is reached. It is determined whether or not the number count is equal to or greater than a set rotation speed Cc (a plurality, for example, 2) (step S9). At this time, since the rotation number count is 1, it is less than the set rotation number Cc (for example, 2), and as a result, it returns to the state of receiving a signal from the mouse 2 with a wheel (step S1). Thereafter, when the receiving means R receives a signal from the mouse 2 with a wheel, it determines whether or not the time interval with the previous input signal from the mouse 2 with a wheel is within T (for example, 100 msec) (step S2). If it is within T, the signal from the wheeled mouse 2 is ignored until T is exceeded. That is, even if a signal from the mouse 2 with a wheel is received, the received signal ignore flag is ON, so the signal from the mouse 2 with a wheel is ignored until the time interval with the previous input signal exceeds T. It is.

  Thereafter, when the time interval with the previous input signal exceeds T, it is determined whether or not the time interval with the previous input signal is equal to or greater than Tamin (for example, 500 msec larger than T) (step S12). If the time interval with the previous input signal is less than Tamin, the reception signal ignorance flag is turned off, and the signal from the wheeled mouse 2 is not ignored (step S14), and the signal from the wheeled mouse 2 is received. Return to the state of reception (step S1). And the signal output from the mouse | mouth 2 with a wheel is processed like the above-mentioned. That is, when a signal from the mouse 2 with a wheel is received, it is determined whether or not the time interval with the previous input signal is within T (step S2). The signals are recognized as signals in (one action), and these signals are stored together in the stack (step S3). Since the received signal ignore flag is OFF (step S4), the rotation amount calculation means 10 calculates the total rotation amount from the total number of signals of one action stored in the stack, and the calculated total rotation amount is It is determined whether or not it is greater than or equal to the set rotation amount Rmin (step S5). If it is determined that the total rotation amount of one action is greater than or equal to the set rotation amount Rmin, the received signal ignore flag is turned ON (step S6), and the subsequent signals from the mouse 2 with a wheel are ignored and not captured. After entering the state, the process proceeds to the next judgment. Next, the rotation speed calculation means 9 calculates the rotation speed of the received signal in one action from the total number of signals of one action stored in the stack, and the calculated rotation speed is equal to or higher than the set rotation speed Vc. It is determined whether or not (step S7). When it is determined that the rotation speed of the received signal within one action is equal to or higher than the set rotation speed Vc, the operation number detecting means 11 increments the rotation number count by 1 (step S8). At this time, since the number of rotations of the rotation number count is added to what was counted last time, the forced scroll execution means 7 indicates that the rotation number count is equal to or greater than the set rotation number Cc (for example, 2). Determination is made (step S9), and the forced scroll execution means 7 forcibly scrolls the display screen 1A for a predetermined time at a set speed faster than the maximum speed in the normal scroll execution means 6 (step S10).

  Only when the total rotation amount calculated in this way is equal to or greater than the set rotation amount Rmin, the calculated rotation speed is equal to or greater than the set rotation speed Vc, and the rotation speed count is equal to or greater than the set rotation speed Cc (for example, 2). Since the configuration is such that the forced scroll execution means 7 is executed, the forced scroll execution means 7 can be executed accurately. In addition, by changing the settings of the set rotation amount Rmin, the set rotation speed Vc, and the set rotation speed Cc, it is possible to change the condition (timing) for executing the forced scroll execution means 7 in accordance with the individual operation situation.

  If the rotational speed of the received signal is not equal to or higher than the set rotational speed Vc in step S7, the rotational speed count is reset (step S11). In step S12, if the time interval with the previous input signal is equal to or greater than Tamin (eg, 500 msec), the rotational speed count is reset (step S13), the received signal ignore flag is turned OFF, and the mouse with wheel 2 The signal is taken in without ignoring the signal (step S14), and a standby state is entered.

  Next, a second embodiment of scroll speed control will be described based on the flowcharts of FIGS. FIG. 6A is a flowchart of reception flag control, which operates based on a reception signal from the mouse 2 with a wheel. That is, when a signal is input from the wheeled mouse 2 (step S20), the receiving means R receives the input signal (step S21), stores the received signal in the stack (step S22), and then receives a reception flag. Is turned ON (step S23). This processing is performed every time a signal is input from the mouse 2 with a wheel.

  As shown in FIG. 6B, when a timer event for processing at a fixed time interval is issued from the computer, timer event processing is executed (step S30), and it is determined whether or not the reception flag is OFF. (Step S31). If the reception flag is ON, it is determined that the signal from the mouse 2 with a wheel is stored in the stack, and the non-reception time until the next signal from the mouse 2 with a wheel is received is added (step S32). It is determined whether or not the added non-reception time is equal to or longer than the set time T (step S33), and if it is less than the non-reception time, all the signals in the stack are processed as one action (signal group), It is stored in the stack (step S34). Subsequently, the rotation amount calculation means 10 calculates the total rotation amount within one action from the total number of signals of one action stored in the stack, and the calculated total rotation amount is equal to or greater than the set rotation amount Rmin. It is determined whether or not there is (step S35). When it is determined that the total rotation amount of one action is greater than or equal to the set rotation amount Rmin, the process proceeds to the next determination. Next, the rotation speed calculation means 9 calculates the rotation speed of the signal within one action from the total number of signals of one action stored in the stack, and the calculated rotation speed is equal to or higher than the set rotation speed Vc. It is determined whether or not there is (step S36). When it is determined that the rotation speed is equal to or higher than the set rotation speed Vc, the operation number detecting means 11 increments the rotation number count by 1 (step S37).

  Subsequently, it is determined whether or not the rotation speed count is equal to or greater than a set rotation speed Cc (for example, 2) (step S38). Since the rotational speed count is 1, it is determined that the rotational speed count is less than the set rotational speed Cc (for example, 2), and the process returns to the timer event process again (step S30). When the timer event process is executed (step S30), it is determined whether or not the reception flag is OFF (step S31), as described above, and if the reception flag is ON, the mouse 2 with a wheel is used. Is stored in the stack, and the non-reception time until the next signal from the mouse 2 with a wheel is received is added (step S32). It is determined whether or not the added non-reception time is equal to or longer than the set time T (step S33). If it is less than the non-reception time, all signals in the stack are processed as one action and stored in the stack. (Step S34).

  Next, the rotation amount calculation means 10 calculates the total rotation amount of one action from the total number of signals of one action stored in the stack, and whether the calculated total rotation amount is equal to or greater than the set rotation amount Rmin. It is determined whether or not (step S35). When it is determined that the total rotation amount of one action is greater than or equal to the set rotation amount Rmin, the process proceeds to the next determination. Further, the rotation speed calculation means 9 calculates the rotation speed of the signal within one action from the total number of signals of one action stored in the stack, and the calculated rotation speed is equal to or higher than the set rotation speed Vc. Whether or not (step S36). When it is determined that the rotation speed is equal to or higher than the set rotation speed Vc, the operation number detecting means 11 increments the rotation number count by 1 (step S37). At this time, since the rotation number of the rotation number count becomes 2, it is determined that the rotation number count is equal to or greater than the set rotation number Cc (for example, 2) (step S38), and the forced scroll execution means 7 executes the normal scroll. The display screen 1A is forcibly scrolled for a predetermined time at a set speed faster than the maximum speed in the means 6 (step S39).

  If the reception flag is OFF in step S31, it is determined that the signal from the wheeled mouse 2 is not stored, the non-reception time is reset (step S40), and the next timer event processing is performed. Wait until it is done. If it is determined in step S35 that the total rotation amount of one action is less than the set rotation amount Rmin, or if it is determined in step S36 that the rotation speed is less than the set rotation speed Vc, the rotation speed count is calculated. After resetting (step S41), the process waits until the next timer event process is performed.

  In addition, this invention is not limited to the said embodiment, A various change is possible in the range which does not deviate from the summary of this invention.

  In the above-described embodiment, the signal number determination unit 5 includes the rotation speed calculation unit 9, the rotation amount calculation unit 10, and the operation count detection unit 11. A configuration including any one of the calculation means 10 and the operation frequency detection means 11 may be adopted. Further, in addition to a configuration in which all the set values (set rotation speed, set rotation amount, set rotation speed) of these three means can be changed, a configuration in which at least one set value can be changed may be used.

  In the above embodiment, the forced scroll execution means 7 is executed to change the setting speed to a higher speed than the maximum speed in the normal scroll execution means 6 and the display screen 1A is forcibly scrolled for a predetermined time. The configuration may be such that the display screen 1A is forcibly scrolled at a low speed for a predetermined time by changing to a set speed slower than the minimum speed in the normal scroll execution means 6.

  In the embodiment, a personal computer is used. However, various computers such as a microcomputer, an office computer, and a process computer can be used.

  In the above embodiment, a mouse with a wheel is shown as the scroll operation means. However, in addition to a mouse without a wheel provided with a switch, a keyboard or a dedicated input means may be used. Any configuration may be used as long as a signal can be input.

  In the above embodiment, when the time interval with the previous input signal is within T, the signal is stored as a signal in one action, and the total rotation amount of the wheel 2B is set as the set rotation amount Rmin from the stored total number of signals. When the rotational speed is determined to be equal to or higher than the set rotational speed Vc, the process proceeds to the next determination. For example, a total number of signals is calculated every predetermined time by a timer or the like, and the total is calculated. It may be determined whether or not the number of signals is equal to or greater than the set number of signals, and when it is determined that the total number of signals is equal to or greater than the set number of signals, the next determination may be made.
