BEST MODE FOR CARRYING OUT THE INVENTION (Embodiment) Hereinafter, an embodiment of the present invention will be described in detail based on an embodiment shown in the drawings. The present invention is not limited to this. FIG. 1 is a block diagram showing an embodiment of the display scroll device of the present invention. In FIG. 1, reference numeral 1 denotes a scroll key, which is provided for instructing display scroll in forward and reverse directions. Further, a display unit for displaying information held by the device, a central control unit for controlling input information or output information by various commands, and a rewritable storage means R
An AM 4 and a ROM 5 for storing a program for operating the apparatus are provided.

The RAM 4 stores a count value memory 4-1 for storing a time during which the scroll key 1 is continuously pressed to switch the scroll unit, and a reference count value memory for storing a count value serving as a reference for the count value memory 4-1. 4-2, release time count value memory 4-3 for storing time for comparing with time from when finger is released from scroll key 1 until next time scroll key 1 is pressed, in which direction the scroll key 1 is currently located Direction memory 4-4 for storing whether or not it is pressed, address book data "A row",
An index memory 4-5 for storing an index for managing by “ka row” and an address book data storage unit 4-6 for storing address book data are provided. A data storage unit for storing is also provided.

Assuming that the reference count value memory 4-2 has "3 seconds" and the release time count value memory 4-3 has "1".
The explanation will be made assuming that the time of "second" is stored. Also, in the address book data storage unit 4-6, personal data such as personal name, home telephone, home address and the like, and personal name in the adr item are sequentially displayed. The address pointer of the next data at the time of arrangement is stored, and the index memory 4-5 stores “a”, “ka”, and
The address pointer of the head data by each index is stored together with the word such as "sa".

The count value memory 4-1 stores the contents of the reference count value memory 4-2 as an initial value. When the lower part of the scroll key 1 is pressed, a signal is output to the scroll instruction detection unit 3-1 and the direction detection unit 3-2. The scroll instruction detection unit 3-1 outputs a signal for setting the flip-flop 3-3 (hereinafter referred to as FF3-3) when the scroll key 1 is pressed, and F
A signal "1" is output from the output Q1 of the F3-3 to the counter 3-4, and the counter 3-4 starts counting up.

The direction detecting section 3-2 detects which direction of the scroll key 1 is pressed, and the RAM is detected.
4 direction memory 4-4 holds the detected direction. The count value at that time is constantly output from the counter 3-4 to the count value detection unit 3-6. Further, the count value detection unit 3-6 outputs a signal to the scroll drive unit 6, and the scroll drive unit 6 outputs 1 as the first unit.
Data is read from the address book data storage unit 4-6 of the RAM 4 for line scrolling, and this data is added.
The scroll control is sequentially performed based on the address pointer stored in the r item, and scroll display is performed on the display unit 2.

In the count value detecting section 3-6, the counter 3
-4 compares the count value output from -4 with the value of the count value memory 4-1 of the RAM 4. As a result of the comparison, if the value of the counter 3-4 becomes the same as the count value memory 4-1 of the RAM 4, a new signal is output from the count value detecting unit 3-6 to the crawl driving unit 6, and the scroll driving unit 6, the address book data storage unit 4 of the RAM 4
Based on the address pointer stored in the adr item of the data currently displayed at the beginning of -6, the address book data 9th ahead is read out, and the operation of displaying it on the display unit 2 is repeated. Page scroll is performed. Note that the address book data 9 ahead is read out because it is assumed that one page of the address book is composed of data for 9 lines.

In the count value detection unit 3-6, when the count value output from the counter 3-4 and the value in the count value memory 4-1 of the RAM 4 match, a signal is sent to the specific value setting unit 3-7. Then, the specific value setting section 3-7 causes the count value memory 4-1 to store the data of "6 seconds" stored in the reference count value memory next.

When the user continues to press the lower part of the scroll key 1, the count value detecting section 3-
6, the count value output from the counter 3-4 and RA
The values of the count value memory 4-1 of M4 are compared, and when they become the same, the count value detection unit 3-6 outputs a signal to the scroll drive unit 6 again.

The scroll driving unit 6 detects that a signal has been sent after page scrolling, and scrolls in index units, which is the third unit. For scrolling in index units, access the index memory 4-5 of the RAM 4 and select the current index "A row".
The operation of reading the address pointer of the next index "ka row" of, reading the data of the address book data storage unit 4-6 corresponding to the address pointer and displaying it on the display unit 2 is repeated.

Further, when the finger is released from the scroll key 1, the scroll instruction detection section 3-1 outputs a signal for resetting the FF 3-3, whereby the FF 3-3 changes to the output Q1 and outputs from Q2. The 1 "signal is output and output to the clearing section 3-5, and the clearing section 3-5 clears the value of the counter 3-4 to" 0 ".

Further, the clearing section 3-5 is a specific value setting section 3
A signal is also output to -7, and the count value memory 4-1
Is set to a reference value of 3 seconds. The output Q2 from the FF 3-3 is also output to the release time counter 3-8, and upon receiving this signal, the release time counter 3-8.
Starts counting. The release time counter 3-8 always outputs the count value at that time to the count value detection unit 3-9.

The count value detector 3-9 compares the count value output from the release time counter 3-8 with the value of the release time count memory 4-3 of the RAM 4. As a result of the comparison, if the value has not been reached, a signal indicating that it has not reached the specific value setting unit 3-7 is output.

When the user reverses the scroll key 1 after releasing the finger from the scroll key 1, the direction detecting unit 3-2 reads the previously designated direction from the direction memory 4-4 of the RAM 4. Then, the direction is compared with the current direction, and it is determined whether the direction is the opposite direction. If it was in the opposite direction,
A signal is sent to the specific value setting unit 3-7.

The output Q1 of the FF3-3 is also output to the specific value setting section 3-7. The specific value setting section 3-7 receives the signal "1" from the output Q1 of the FF3-3, Further, from the count value detection unit 3-9, the release time counter 3-
8 receives a signal that the count value output from 8 has not reached the value of the release time count memory 4-3 of the RAM 4 and a signal that the reverse direction is instructed from the direction detection unit, the count value memory 4 Set the value of -1 to "5 seconds".

Since the value of the count value memory 4-1 is "5 seconds", the timing for switching to the next scroll unit is every 5 seconds when the scroll key 1 is continuously pressed. Further, as a result of comparison between the count value output from the release time counter 3-8 and the value of the release time count memory 4-3 of the RAM 4, the value of the release time counter 3-8 is RA.
If it reaches the release time count memory 4-3 of M4,
A signal is output from the count value detecting unit 3-9 to the specific value setting unit 3-7, and the specific value setting unit 3-7 outputs the count value detecting unit 3-7.
By receiving the signal of -9 and setting the value of the count value memory 4-1 to "3 seconds" which is the reference value, the scroll unit switching every 3 seconds described earlier is performed.

A signal is also output from the output Q1 of the FF 3-3 to the clear section 3-5, and the scroll key 1
When is pressed, the clear unit 3-5 sets "0" in the release time counter 3-8. In the present embodiment, the case of scrolling up and down is given as an example.
Even when scrolling to the left and right, the operation of this embodiment can be similarly applied.

FIG. 2 is a display screen diagram showing a display scroll state according to the present invention. When the address book application is started, as shown in FIG. 2 (A), nine data from the beginning of the data of "A row" are displayed, and the leading data is inverted.

When the lower part of the scroll key 1 is pressed, the reversed lines are moved downward one line at a time, and one line is scrolled. If you continue to press the lower part of the scroll key 1 for 3 seconds without releasing it, the one-line scroll automatically changes to the one-page scroll, and the next page is displayed as shown in FIG. Repeats one-page scroll at a speed that can be read by a person. Further, if the lower part of the scroll key 1 is kept pressed for 3 seconds without being released, the one-page scroll is automatically changed to the index-by-index scroll, and as shown in FIG. "Ka line" is displayed, and the index scroll is repeated as "ka line"->"saline"->"taline" at a user-readable speed.

For example, when the user wants to find out the telephone number of the person "Hiramatsu", the lower part of the scroll key 1 is kept pressed until the index scroll is performed as described above, and "ha line" is displayed. Then, the finger may be released from the scroll key and the upper or lower portion of the scroll key 1 may be pressed to scroll in order to display the data of the person "Hiramatsu".

[0032] Further, since "Ha line" is desired to be displayed, the lower portion of the scroll key 1 is kept pressed and the user goes too far, and as shown in Fig. 3 (A), "Ma line" is displayed. In this case, immediately by pressing the upper portion of the scroll key 1, the scroll operation is started in the reverse direction. In the scroll operation at this time as well, as in the case where the lower portion of the scroll key 1 is continuously pressed, one line scroll, one page scroll, and index scroll each time the button is pressed for 3 seconds.
The scroll unit is changed automatically.

However, when the lower part of the scroll key 1 is continuously pressed and released, and then the upper part of the scroll key 1 which is the reverse direction is pressed within 1 second, the change of the scroll unit is not 5 seconds but 5 seconds. It is set to a second interval and longer. Therefore, if the data is scrolled too far from the data to be examined, for example, by pressing the scroll key 1 in the reverse direction immediately within 1 second, it is possible to easily return without returning too much. The desired data can be reached.

In this case, after the lower part of the scroll key 1 is continuously pressed and released, as shown in FIG. push. Immediately after pressing the upper part of the scroll key 1, one line is scrolled, and as shown in FIG. 3 (B), the last data of "ha line" is displayed, and one line is sequentially scrolled in the reverse direction. I do. Further, when the upper part of the scroll key 1 is pressed and kept pressed for 5 seconds, the scroll is changed page by page, and as shown in FIG. 3C, when the data of "Hiramatsu" is displayed, the scroll key 1 Remove your finger from.

Next, the relationship between the scroll unit and the time during which the scroll key 1 is kept pressed will be described with reference to FIGS. FIG. 4 shows the transition of the scroll unit when the lower part of the scroll key 1 is continuously pressed to scroll forward and the upper part of the scroll key 1 is immediately pressed to instruct to scroll in the reverse direction. It is a graph that is shown. To scroll forward at the start of the scroll instruction shown in the figure, the lower portion of the scroll key 1 is pressed.

Initially, scrolling is performed in the first scroll unit for scrolling one line (area a). Further, when the scroll key 1 is continuously pressed and counted for 3 seconds, scrolling is performed in the second scroll unit for performing page scroll (area b). ). When the lower part of the scroll key 1 is further pressed, scrolling is performed in the third scroll unit for index scrolling when 3 seconds have been counted (area c).

As shown in the figure, when the lower portion of the scroll key 1 is continuously pressed and 10 seconds have passed, the finger is released from the lower portion of the scroll key 1 and the backward scroll is performed within 1 second (area d). When the upper part of the scroll key 1 is pressed, one-line scroll is started (area e). Immediately at this time, by pressing the upper part of the scroll key 1, by continuing to press the scroll key 1, the page scroll is switched at the time when 5 seconds have been counted from the start of the reverse scroll instruction, and the upper part of the scroll key 1 is continuously pressed. While scrolling, page scroll is performed (area f).

After switching to page scrolling, if the upper portion of the scroll key 1 is pressed for a further 5 seconds, it is switched to index scrolling and index scrolling is performed until the finger is released from the upper portion of the scroll key 1 (area g). As above. After pressing and holding scroll key 1 to increase the scroll unit, release the finger from scroll key 1 and press reverse scroll key 1 within 1 second. The unit can be switched, and the scroll unit until switching can be maintained longer than the initial switching time.

FIG. 5 shows a case where the lower part of the scroll key 1 is continuously pressed to scroll forward, and after a while, the upper part of the scroll key 1 is pressed to instruct to scroll backward. It is a graph showing the transition of the scroll unit of.

The lower portion of the scroll key 1 is pressed in order to scroll in the forward direction at the start of the instruction shown in the figure. Initially, scrolling is performed in the first scroll unit that performs one-line scrolling (area a), and if the scroll key 1 is continuously pressed and counted for 3 seconds, page scrolling is performed.
Scroll in scroll units (area b). When the lower part of the scroll key 1 is further pressed, scrolling is performed in the third scroll unit for index scrolling when 3 seconds have been counted (area c).

As shown in the figure, in order to scroll backward in 10 seconds after pressing the lower part of the scroll key 1, release the finger from the lower part of the scroll key 1 and wait for 2 seconds (area h). When the upper part of the scroll key 1 is pressed, the one-line scroll is started (area i).

If the upper portion of the scroll key 1 is continuously pressed as it is, the page scroll is performed at the time point when 3 seconds are counted from the time when the reverse scroll instruction is started, and the page scroll is performed while the upper portion of the scroll key 1 is continuously pressed. (Area j).

After switching to page scrolling, if the upper portion of the scroll key 1 is pressed for another 3 seconds, the index scrolling is performed, and index scrolling is performed until the finger is released from the upper portion of the scroll key 1 (area k).

As described above, when the scroll key 1 is continuously pressed to increase the scroll unit, the finger is released from the scroll key 1 and the scroll key 1 in the reverse direction is pressed for more than 1 second, and the key is continuously pressed. During this period, the scroll unit is switched every time 3 seconds are counted, and the scroll unit until switching is maintained for the same time as the initial switching time.

FIG. 6 shows a scroll in the case where the lower part of the scroll key 1 is pressed to scroll forward one line, and the upper part of the scroll key 1 is immediately pressed to instruct to scroll in the reverse direction. It is a graph showing the transition of the unit.

At the start of the scroll instruction shown in the figure, the lower portion of the scroll key 1 is pressed to scroll forward. Initially, scrolling is performed in the first scroll unit in which one line is scrolled (area 1), and when the scroll key 1 is continuously pressed for 2 seconds, the scroll key 1 is scrolled.
When the upper part of the scroll key 1 is pressed in order to scroll in the opposite direction after releasing the finger from the lower part for 1 second (area m), scrolling in one line starts in the opposite direction (area n).

If the upper portion of the scroll key 1 is kept pressed as it is, the page scroll is switched at the time when 3 seconds are counted from the start of the reverse scroll instruction, and the scroll key 1
The page is scrolled while the upper part of is kept pressed (area o). After switching to page scrolling, 3 more
If the upper part of the scroll key 1 is kept pressed for a second, the mode is switched to the index scroll, and the index scroll is performed until the finger is released from the upper part of the scroll key 1 (area p).

As described above, when the finger is released from the scroll key 1 before the scroll unit becomes large, while the reverse scroll key 1 is continuously pressed within 1 second, Since the scroll unit is switched every time 3 seconds are counted, the scroll unit switching time does not increase even if the lower part of the scroll key 1 is pressed and then the upper part is immediately pressed as shown in FIG.

7 and 8 are flowcharts showing the scroll processing for performing the above operation. When the application is activated, as shown in FIG. 2 (A), the display starts from the head data of "A row". In step S1, it is determined whether or not the scroll key has been operated. In step S2, the time increment setting is set to 3 seconds.

In the above description of the embodiment, the count value memory 4 is created by using the scroll unit switching times of 3 seconds, 6 seconds, etc., which are sequentially stored in the reference count value memory 4-2.
-1 was updated, but an example in which this value is switched in the increase setting will be described here.

In step S3, the push time counter 3-4 of the central controller 3 is set to "0" to prepare for the push time count. In step S4, the count value memory 4-1
Is set to "0". In step S5, the value set to increase the time in the count value memory 4-1 is increased.

Since the operation of the scroll key 1 has just begun, the increased value of 3 seconds becomes the value of the count value memory. In step S6, the direction in which the scroll key 1 is pressed is held. In step S7,
The time of the push time counter 3-4 is increased in units of 0.25 seconds, for example.

In step S8, the displayed cursor is moved line by line to the next line. At this time, if scroll processing is required on the screen, scroll processing is performed. In step S9, it is determined whether or not the input by the scroll key 1 has been released. If it is determined that it has not been released, the process proceeds to the next step S10, and if it is determined that it has been released, step S18 Go to.

In step S10, it is judged whether or not the value increased by the counter UP in step S7 has reached the value increased in step S5, and the value increased in step S7 is determined.
If it is determined that the counter UP value has not reached in step S7, the process returns to step S7, and if it is determined that the counter UP value in step S7 has reached the increased time, step S7 is performed. Proceed to S11. In step S11, the time set to increase is added to the value in the count value memory 4-1.

That is, if the value set to increase is 3,
When the value of the count value memory 4-1 is 3, the value of the count value memory is increased to 6. In steps S12 to S15, the same processes as steps S7 to S10 are performed. However, the unit that the cursor is moved (scrolled) in step S13 is changed from a line unit to a page unit.

Further, the step S16 is different in that the unit is the index of the Japanese syllabary.
In step S17, the scroll unit is the maximum, so the time determination means is also deleted.

When it is determined in step S9, step S14, or step S17 that the scroll is canceled, the process proceeds to step S18, and it is determined whether or not the count value is three. If the count value is 3, the previous scroll time is short, the normal scroll is started without performing any processing for the next scroll, and the processing is ended for the time being.

When it is determined in step S18 that the count value is not 3, the process proceeds to step S19. In step S19, the release time counter 3-8 is set to "0" to prepare for counting. In step S20, the release time counter 3-8 is incremented by 0.2, for example.

The release time counter 3-8 outputs the release time count value memory 4-by the count UP in step S20.
In step S21, it is determined whether the value 1 stored in 3 is reached, and the process is ended by determining that the value 1 is reached. This is to determine whether or not the next scroll has been performed continuously since the previous scroll instruction.If there is no scroll key instruction in the reverse direction continuously within the specified time, the next scroll The key is to start as a normal process.

In step S22, it is determined whether or not scrolling in the same direction is continuously instructed, and it is detected that continuous scrolling is instructed. Therefore, in step S25, the increase setting is set to 3 and then step S3 is performed. Return. Step S2
In step S23, it is determined that the scrolling in the same direction is not continuously instructed.
It is determined whether scrolling in the reverse direction has been instructed.

By determining the instruction of scrolling in the reverse direction in step S23, the amount increase setting is set to 5 in step S24. Step S22, Step S2
The determination of the direction 3 can be made by comparing the direction held in step S6 with the direction currently instructed. The setting in step S23 lengthens the time until the scroll unit is changed in the next scroll.

That is, the pointing direction from the previous time has changed,
If the count value is not 3 (the previous scroll unit is not a line) and a scroll instruction is issued within 1 second after the cancellation, the increase setting is changed to 5. By setting the increase amount to 5, the value to be increased in step S5 and step S11 changes from 3 to 5, and when the above conditions are not met, the value returns to 3.

By the above processing, the scroll unit is increased by continuously pressing the scroll instruction button for a certain period of time, and when the scroll unit becomes large, the scroll instruction is stopped, and immediately when the reverse scroll instruction is issued. The time interval for increasing the scroll unit can be increased.

[0064]

Since the present invention is constructed as described above, it has the following effects. According to the invention of claim 1 , when a large amount of data is required to be scrolled significantly, the scroll unit is increased by continuously pressing the scroll instruction button for a certain period of time, and the data is transferred at a high scroll speed. Since it can be displayed, it is not necessary to hold down the scroll instruction button for a long time until the desired data appears, and the desired data can be displayed quickly from a large amount of data without the user performing unnecessary operations. You can

[0065] The first, second, a scroll instruction can be carried out in different directions, exit the scroll instruction of the first direction scrolls unit is increased, scroll instruction to the second direction are opposite to each In this case, since the time interval for enlarging the scroll unit when scrolling in the second direction becomes large, desired data can be easily displayed.

According to the second and third aspects of the invention,
In the invention according to claim 1, and ends the scroll instruction of the first direction scrolls unit is increased, if the immediately performs a scroll instruction to a second direction which is opposite direction, scroll in the second direction Since the time interval for enlarging the scroll unit at the time of doing becomes large, even if the scroll switching unit is too large and goes too far, it is less likely to return too much, and desired data can be easily displayed.
