Are often configured to accept printing conditions from the user.

JP 2011-252970 A

However, recently, printer functions have increased, and the number of icons for setting printing conditions tends to increase. Therefore, in a portable terminal with a limited display screen size, the size of each icon has to be reduced, and this makes it easier to make an input error due to a tap operation.
That is, if the icon size is small, when the user taps with a finger, there is a possibility that the finger touches not only the target icon but also the icon next to it, and the wrong icon is input. In particular, when operating a mobile terminal with one hand, the back of the mobile terminal is usually supported by four fingers other than the thumb, and the icon is tapped with the belly of the thumb. It is difficult to perform delicate tap operations, and the base of the thumb hits the screen when tapping, and there is a high possibility that an unintended input operation will be performed.

Such a problem is not only a print condition setting input operation by a mobile terminal, but also accepts a selection of some icons, and accepts an operation such as launching an application or selecting a file associated with the selection of a portable input. It can occur in devices in general.

<First Embodiment>
A first embodiment of a portable input reception device according to the present invention will be described with reference to the drawings, taking a portable terminal connected to a digital color multifunction peripheral (MFP) as an example.
Hereinafter, in this specification, a digital color multifunction peripheral is simply referred to as a “multifunction peripheral”.
FIG. 1 is a diagram illustrating a state in which the mobile terminal 1 according to the present embodiment is connected to the multifunction device 200.

The multi-function device 200 has functions of a printer, a copy, a facsimile, a scanner, and a finisher function such as sorting and stapling, and the mobile terminal 1 is connected via wireless communication (for example, Bluetooth (registered trademark)). Other terminals are connected via a network (not shown) (for example, a LAN).
In addition, when the MFP 200 receives an instruction to execute a print job from the portable terminal 1 or another terminal, the MFP 200 is configured to execute print processing based on the instruction.

(1) Configuration of Mobile Terminal FIG. 2 is a block diagram showing the configuration of the mobile terminal 1.
The portable terminal 1 is, for example, a small tablet personal computer, and as shown in FIG. 2, a control unit 10, a display / input unit 11, a three-axis acceleration sensor 13, a power button 12, and a battery (not shown) Etc.).

The control unit 10 includes a CPU (Central Processing Unit) 101, a ROM (Read Only Memory) 102, a RAM (Random Access Memory) 103, a communication I / F unit 104, a printing condition storage unit 105, an icon array storage unit 106, and the like. .
The CPU 101 executes a program for controlling the display / input unit 11, the communication I / F unit 104, and the like. The ROM 102 is a storage that stores various programs executed by the CPU 101. The RAM 103 is a work area when the CPU 101 executes a program. The communication I / F unit 104 is an interface for wirelessly communicating with the control unit 210 of the multifunction device 200, and has an antenna for transmitting and receiving radio waves therein.

The printing condition storage unit 105 stores various printing conditions for instructing the MFP 200 to print.
The icon array storage unit 106 stores image data for each icon for setting printing conditions and information regarding the memory address of each icon.
FIG. 3 is a tree diagram showing an example of a hierarchy of setting items for print conditions in the present embodiment.
As shown in the figure, print condition setting items include color, image quality, density, paper size, printing direction, duplex / single-sided, page aggregation, finishing, number of copies (item icons 2a to 2i). Further, for example, the color setting contents include color and monochrome in the lower hierarchy (setting icons 2a1 and 2a2), and the paper size setting contents include A3, A4, A5, B4 and B5 sizes in the lower hierarchy. (Setting icons 2d1-2d5). Similarly, other setting items (excluding the number of copies to be printed) are provided with setting contents in the lower hierarchy. The number of copies to be printed is set by numerical input.
Image data of an item icon array 20 in which item icons representing upper setting items are arranged, and image data of setting icon arrays 21 to 28 in which icons representing specific contents below each item are arranged, They are stored in different page memories in the icon array storage unit 106. The page memory of the lower icon array is associated with the page memory of the upper icon array. For each page memory, a table is created in which the contents of the displayed icon are associated with the memory addresses at the four corners of the rectangular icon.

In FIG. 3, the default value of each setting item is surrounded by a thick frame. The default value of the numerical value input 29 for the number of print copies is set to “1 copy”. The print condition storage unit 105 stores this default value as an initial value.
The display / input unit 11 includes a display panel 111 in which a backlight 112, an LCD (Liquid Crystal Display) 113, and a touch panel 114 are stacked, an LCD controller 115 provided for driving control of the display panel 111, a VRAM (Video Random Access Memory) 116, touch panel controller 117, and the like.

  The VRAM 116 is a memory for storing image data to be displayed on the LCD 113. The LCD controller 115 drives and controls the LCD 113 and displays the image data stored in the VRAM 116 on the LCD 113. The CPU 101 stores image data to be displayed on the LCD 113 in the VRAM 116 and controls the LCD controller 115 to display the image data on the LCD 113.

  The touch panel controller 117 drives and controls the touch panel 114, generates an input signal in response to a user touch operation received via the touch panel 114, and outputs the input signal to the CPU 101. Thereby, the CPU 101 can detect a user's touch operation, for example, an operation of selecting a specific icon by tapping, or an operation of flicking and scrolling the screen.

Here, “flick” means an operation in which a fingertip is brought into contact with the screen and the fingertip is slid as if it is lightly flicked toward a direction in which the display image is to be moved. In addition, “scrolling” refers to, for example, moving the display image to the right so that the left part that was not visible on the screen can be seen is called right scrolling, and vice versa.
The triaxial acceleration sensor 13 detects the accelerations Ax, Ay, and Az in the triaxial directions of the X axis, the Y axis, and the Z axis that accompany the movement operation of the mobile terminal 1, and outputs them to the CPU 101. Here, the X-axis direction is the horizontal direction (left-right direction) of the display panel 111, the Y-axis direction is set to be the vertical direction of the display panel 111, and the Z-axis direction is set to be perpendicular to the panel surface ( (See FIG. 4 (a)).

The CPU 101 obtains the moving direction, moving speed, and moving amount from the accelerations Ax, Ay, Az detected by the triaxial acceleration sensor 13 in consideration of the gravitational acceleration applied to the mobile terminal 1, and the X, Y of the mobile terminal 1 is obtained. , Detection of movement in the Z-axis direction (parallel movement).
Further, the CPU 101 can detect an inclination amount (rotational movement amount) with respect to an axis parallel to any of the X, Y, and Z axis directions based on the change amounts of the accelerations Ax, Ay, and Az (for example, FIG. b)). Note that a method for detecting the rotational movement amount based on the detection value of such a three-axis acceleration sensor is known per se, and will not be described here.

The CPU 101 controls to scroll the display screen according to the moving direction or to enlarge / reduce the display magnification when detecting the above-described parallel movement or rotational movement of tilting the mobile terminal 1 during a specific screen display. Hereinafter, this control will be described.
(2) Control of display screen scrolling and display magnification enlargement / reduction FIG. 4A is an example showing a printing condition setting screen 40 for setting printing conditions, and an initial screen thereof is displayed.

The print condition setting screen 40 shown in the figure includes a title bar 40a, an icon display area 40b, and a button display area 40c on which a print start button 41 and a reset button 42 are displayed.
The control unit 10 generates image data of the title bar 40a, the icon display area 40b, and the button display area 40c of the printing condition setting screen 40, stores them in the VRAM 116, and controls the LCD controller 115 to display them on the LCD 113. .

Among them, as the image data to be displayed in the icon display area 40 b, image data of the item icon array 20 in which the item icons 2 a to 2 i shown in FIG. 4C are arranged in a horizontal row is generated and stored in the VRAM 116. In FIG.4 (c), the part H enclosed with the broken line is displayed on the icon display area 40b.
The print start button 41 is an icon button for instructing the start of printing after the user finishes setting the printing conditions. The reset button 42 is an icon button for returning the printing conditions to the default values. The print start button 41 and the reset button 42 are designed so that they can be operated with only one hand so that they are not separated as much as possible. When tapping one of the buttons, the finger or the base of the finger should not touch the other button. In addition, it is arranged at a position where the space between the buttons is secured.

In the present embodiment, the icon display area 40b in which the item icon array 20 is displayed in the print condition setting screen 40 is the target of scrolling and enlargement / reduction of the display magnification. Therefore, hereinafter, the “display screen” for enlarging / reducing the scroll and the display magnification means the “icon display area 40b” of the print condition setting screen 40.
First, scrolling of the display screen will be described.

  For example, when the user moves the mobile terminal 1 to the right side (X direction), the control unit 10 detects the right side movement from the output result from the triaxial acceleration sensor 13, and according to the detected movement amount. By changing the memory address read from the image data of the item icon array 20 in the icon array storage unit 106, the icon image displayed in the icon display area 40b is scrolled to the left (opposite to the moving direction). The amount of change in the memory address of the image data is set in advance so that the amount of movement of the icon on the screen by scrolling is equal to the amount of movement of the mobile terminal 1.

For example, when the mobile terminal 1 is moved 10 mm in the right direction, the memory address to be read is changed so that the icon image moves 10 mm in the left direction (the pixel pitch of the display screen is changed). If α μm, the memory address is shifted to the left by (10 / α) × 1000 pixels.)
As a result, the user can intuitively scroll the screen and the operability is increased.

The user can display icons on the right side of the item icon array 20 (item icons 2g to 2i in the case of FIG. 4C) in the icon display area 40b.
On the other hand, when the user moves the mobile terminal 1 to the left side (X ′ direction), the control unit 10 scrolls the item icon array 20 to the right side.
Here, the scrollable range of the display screen is set as follows.

First, the left-side scroll is performed until the center point C2 of the rightmost item icon 2f in the item icon array 20 reaches the left-right direction center line CL of the print condition setting screen 40 (see FIG. 5A). Is until the center point C1 of the leftmost item icon 2a reaches the center line CL (see FIG. 5B).
As a result, the leftmost and rightmost item icons 2a and 2f in the item icon array 20 can be moved to the center of the screen, and unnecessary scrolling that prevents any icons from being displayed is prevented. ing.

The same applies to the setting icon arrays 21 to 28, and the scrollable range is set so that the leftmost and rightmost setting icons can be moved to the center of the screen.
Thus, by moving the mobile terminal 1 in the left-right direction, the icons displayed on the print condition setting screen 40 can be switched.

Next, the enlargement / reduction of the display magnification can be performed by moving the mobile terminal 1 in the vertical direction (Z-axis direction) of the display panel 111.
For example, as shown in FIG. 6A, when the user moves the portable terminal 1 held with one hand (left hand) in the Z direction and approaches the user himself / herself, the control unit 10 moves the movement in three axes. It detects from the output result from the acceleration sensor 13, and zooms in on the icon in the center of the icon display area 40b according to the detected movement amount, and displays the enlarged image (see FIG. 6 (b) → (c)). The enlarged display of the icon image can be performed using, for example, a linear interpolation method. In FIG. 6B, the enlarged area is indicated by a broken line.

On the other hand, when the mobile terminal 1 is moved in the Z ′ direction, that is, in a direction away from the user, the control unit 10 zooms out the icon display area 40b according to the detected movement amount and displays the reduced icons. (Refer to FIG. 6 (c) → (b)). The icon image can be reduced and displayed, for example, by thinning out the pixels of the image data in accordance with the reduction ratio.
Then, as shown in FIG. 6 (c), when the number of icons displayed as a whole is one in the icon display area 40b due to the enlargement of the display magnification, the control unit 10 selects the icon by the user. It is comprised so that it may determine with having been carried out.

The determination as to whether or not only one icon is displayed as a whole can be made as follows, for example.
The control unit 10 first displays a part of the icon display area 40b together with the four corner addresses M1, M2, M3, and M4 of each icon image from the memory address of the image data of the item icon array 20 of the page memory of the VRAM 116. The memory address range M10 of H is acquired. If all the four corner addresses M1, M2, M3, and M4 are included in the memory address range M10, it can be determined that the entire icon is displayed in the icon display area 40b, and the number is counted. If there is only one, it is determined that only one icon is displayed as a whole.

This makes it easy for users to select an icon with just one hand, without having to tap the icon. Can do. A process for displaying and selecting a lower level setting icon on the print condition setting screen 40 in FIG. 6C will be described later.
In the present embodiment, the upper limit of the display magnification is an enlargement ratio up to the limit at which at least one icon is entirely displayed. In other words, the memory addresses at the four corners of the specific icon being displayed are not enlarged to the extent that they do not fit within the display range of the icon display area 40b. This is because there is no point in expanding beyond that.

The lower limit (minimum reduction ratio) of the display magnification is set to an appropriate lower limit of the icon size in consideration of individual differences in identification ability such as differences in the user's visual acuity to prevent the icons from becoming too small to be identified. A value is set in advance, and is provided corresponding to the lower limit value.
In the present embodiment, since icons are arranged in a row in the horizontal direction of the display panel 111, the mobile terminal 1 is not scrolled even if it is moved in the vertical direction (Y-axis direction).

Further, when the detected parallel movement direction of the mobile terminal 1 is inclined with respect to the X, Y, and Z axis directions, the direction with the largest movement amount among the movement amounts in the X, Y, and Z axis directions is selected. The mobile terminal 1 is determined to be the moving direction.
Furthermore, in order to prevent scrolling of the display screen and enlargement / reduction of the display magnification due to camera shake, when the moving speed of the mobile terminal 1 instantaneously increases and exceeds a predetermined value, it is determined that camera shake occurs. In the meantime, the display screen is not scrolled or the display magnification is not enlarged or reduced.

Here, the predetermined value is set to an appropriate size in consideration of individual differences based on the speed at the time of camera shake obtained by measurement in advance.
In the case of the rotational movement of the mobile terminal 1, when the amount of tilt (rotation angle) does not exceed a predetermined value, it is determined that the camera shake has occurred and is not detected as the movement of the mobile terminal 1.
(3) Printing Condition Setting Process Next, the printing condition setting process using the printing condition setting screen 40 will be described.

FIG. 7 is a flowchart illustrating an example of control of “print condition setting processing” by the control unit 10.
This process is performed as a subroutine of a main flowchart (not shown) for controlling the entire mobile terminal 1.
As shown in the figure, when receiving a print request from the user (step S1), the control unit 10 displays an initial screen (print condition setting screen 40) in which print condition setting item icons are arranged on the display panel 111 (step S1). 4 (a)) is displayed (step S2), and the flag F = 1 is set (step S3).

The print request in step S1 is accepted as an image to be printed, for example, by tapping a print mark 31 provided on the screen 30 on which characters and photographs as shown in FIG. 8 are displayed.
Thereafter, when the print start button 41 (see FIG. 4A, etc.) is tapped (step S4: Yes), the control unit 10 ends the print condition setting process and returns to the main flowchart (not shown). To do. In this case, the control unit 10 generates a print instruction command while maintaining the default printing conditions, and transmits image data to be printed to the multifunction device 200 together with the print instruction command. At the same time, the original screen (here, the screen 30 in FIG. 8) that received the print request is displayed on the display panel 111. When the print start button 41 is tapped after accepting the print condition setting in the subsequent step, a print instruction command is generated based on the accepted print condition, and the print instruction command and the image data are combined. Send to.

When the print start button 41 is not tapped (step S4: No), the process is divided depending on whether or not the flag F = 1 (step S5).
When the flag F = 1 (step S5: Yes), if the movement of the mobile terminal 1 in the direction perpendicular to the screen or in the left-right direction is detected (step S6: Yes), an item icon selection process is performed (step S6: Yes). Steps S7 to S10). On the other hand, if the flag F is not 1 (step S5: No), if the mobile terminal 1 detects a movement in a direction perpendicular to the screen or a movement tilting in the left-right direction (rotation movement) (step S11: Yes). Then, setting icon selection processing and the like are performed (steps S12 to S15).

(3-1) Item Icon Selection Process FIG. 9 is a subroutine showing the contents of the “item icon selection process” in step S7.
As shown in the figure, when the detected moving direction is the left-right direction (step S21: Yes), the display screen scrolling process A is performed (step S22). When the detected moving direction is the vertical direction, the display magnification is enlarged or reduced. Processing is performed (step S23).

(3-1-1) Display Screen Scroll Processing FIG. 10 is a subroutine showing the contents of “display screen scroll processing A”.
As shown in the figure, when the moving direction of the mobile terminal 1 is the right side (step S31: Yes), the control unit 10 first determines whether or not the screen of the icon display area 40b has reached the right end of the scrollable range. (Step S32).

The determination as to whether or not the right end of the scrollable range has been reached can be made as follows.
For example, as shown in FIG. 5A, when the item icon array 20 is displayed in the icon display area 40b, the control unit 10 first determines from the memory address of the image data of the item icon array 20 on the VRAM 116. The address Mc2 of the center point C2 of the image of the rightmost icon 2i and the memory address range M10a (a part of the memory address range M10) on the left side of the center line CL of the portion H displayed in the icon display area 40b. get. If the address Mc2 is not included in the memory address range M10a, it can be determined that the center point C2 of the icon 2i has not yet come to the left side of the center line CL of the icon display area 40b. It is determined that the right end of the possible range has not been reached.

  When the right end of the scrollable range has not been reached (step S32: No), the control unit 10 displays the screen of the icon display area 40b according to the amount of movement in the X-axis direction obtained from the detection result of the triaxial acceleration sensor. Is scrolled to the left (step S33). If the right end has been reached (step S32: Yes), step S33 is skipped and scrolling is stopped.

The control unit 10 repeats the above steps S32 and S33 while detecting the rightward movement of the mobile terminal 1 (step S34: Yes).
On the other hand, when the moving direction of the mobile terminal 1 is the left side (step S31: No), it is confirmed whether or not the screen of the icon display area 40b has reached the left end of the scrollable range (step S35).

The determination of whether or not the left end of the scrollable range has been reached is the same as the determination of whether or not the right end has been reached, and can be performed as follows.
Reference is now made to FIG. First, the control unit 10 starts from the memory address of the image data of the item icon array 20 on the VRAM 116, the address Mc1 of the center point C1 of the image of the leftmost icon 2a, and the portion H displayed in the icon display area 40b. The memory address range M10b on the right side of the center line CL (a part of the memory address range M10) is acquired. If the address Mc1 is not included in the memory address range M10b, it can be determined that the center point C1 of the icon 2a has not yet come to the area on the right side of the center line CL of the icon display area 40b. It is determined that the left end of the possible range has not been reached.

  When the left end of the scrollable range has not been reached (step S35: No), the control unit 10 displays the screen of the icon display area 40b according to the amount of movement in the X-axis direction obtained from the detection result of the triaxial acceleration sensor. Is scrolled to the right (step S36). If the left end has been reached (step S35: Yes), step S36 is skipped and scrolling is stopped.

While detecting the movement of the mobile terminal 1 to the left side (step S37: Yes), the control unit 10 repeats the above steps S35 and S36.
In such a scrolling process, the user can easily operate intuitively by making the actual horizontal movement amount and scroll amount substantially the same.
The above is the display screen scrolling process A.

(3-1-2) Display magnification enlargement / reduction processing and icon selection Next, FIG. 11 is a subroutine showing the contents of the "display magnification enlargement / reduction processing" in step S23.
As shown in the figure, when the moving direction of the mobile terminal 1 is a direction approaching the user (step S41: Yes), the control unit 10 first displays the icon displayed as a whole in the icon display area 40b. It is confirmed whether there is only one (step S42).

  When there is not only one icon displayed as a whole (step S42: No), the control unit 10 determines that the display magnification has not yet reached the upper limit and determines the Z obtained from the detection result of the three-axis acceleration sensor. The display magnification of the icon display area 40b is enlarged according to the amount of movement in the axial direction (step S43). When only one icon is displayed as a whole (step S42: Yes), step S43 is skipped and the enlargement of the display magnification is stopped.

The control unit 10 repeats the above steps S42 and S43 while detecting the movement in the direction approaching the user of the mobile terminal 1 (step S44: Yes).
On the other hand, when the moving direction of the mobile terminal 1 is the direction away from the user (step S41: No), it is confirmed whether or not the size of the displayed icon is a lower limit value (step S45).

  If the icon size is not the lower limit (step S45: No), the control unit 10 determines that the display magnification has not yet reached the lower limit, and the amount of movement in the Z-axis direction obtained from the detection result of the three-axis acceleration sensor. Accordingly, the display magnification of the icon display area 40b is reduced (step S46). If the icon size is the lower limit (step S45: Yes), step S46 is skipped and the reduction of the display magnification is stopped.

And while the movement to the direction away from the user of the portable terminal 1 is detected (step S47: Yes), said step S45, S46 is repeated.
Here, the icon size can be obtained, for example, as follows.
First, the control unit 10 acquires the four-corner addresses M1, M2, M3, and M4 of the icons that are displayed entirely in the icon display area 40b from the memory address of the image data of the item icon array 20 on the VRAM 116. Next, from the control information of the LCD controller 115, the coordinate information of each pixel associated with the image data on the addresses M1, M2, M3, and M4 is obtained, thereby calculating the number of pixels used for one icon display. And its size can be determined.

The above is the display magnification enlargement / reduction processing.
Returning to FIG. 9, when there is only one item icon displayed in the icon display area 40b as a result of enlargement of the display magnification in Step S24 (Yes), the control unit 10 displays the entire icon. It is determined that the item icon has been selected by the user (step S25).

  For example, as shown in FIG. 6C, when one icon displayed as a whole is an item icon 2d for paper size setting (hereinafter, also referred to as “paper size icon 2d”), control is performed. The unit 10 determines that the paper size icon 2d is selected. On the other hand, when there are two or more icons instead of one displayed as a whole, it is determined that the icon has not yet been selected.

Returning to FIG. 7, when the item icon is selected in step S8 (Yes), the control unit 10 displays the lower setting icon array (step S9) and sets the flag F = 2 (step S9). S10). If the item icon is not selected (step S8: No), steps S9 and S10 are skipped.
After this, if the reset button 42 is not tapped (step S16: No), the process returns to step S4 and the subsequent processing is executed. On the other hand, if the reset button 42 is tapped (step S16: Yes), the print condition setting stored in the print condition storage unit 105 is reset to the default value (step S17), and then the process returns to step S2 to set the print condition. The initial screen of the screen 40 is displayed again and the flag F = 1 is set (steps S2 and S3), and the processing after step S4 is executed.

If the flag F = 2 is set in step S10 and then the reset button 42 and the print start button 41 are not tapped (steps S16 and S4: No), the flag F is not 1 in step S5 (No). The control unit 10 executes steps S11 to S15 such as a setting icon selection process.
(3-2) Setting Icon Selection Processing FIG. 14A is an example of a lower setting icon array display screen, and lower setting displayed immediately after it is determined that the paper size icon 2d is selected. It is a figure which shows the display screen of the icon arrangement | sequence 24. FIG.

  When switching the screen in this way, it is desirable that the user can easily recognize that the screen has been switched, for example, by using an animation or an effect. Then, as in this embodiment, the screen configuration of the display screen of the upper item icon array (see FIG. 6) and the display screen of the lower setting icon array 24 (FIG. 14A) are similar. Even in this case, the user can immediately notice that the screen has been switched.

As shown in the figure, in the present embodiment, when the lower setting icon array is displayed, the control unit 10 displays only one icon as a whole (here, A4 which is the default value of the printing condition). Only the setting icon 2d2 representing the size is displayed as a whole), and the display magnification is adjusted and displayed. This is due to the following reason.
As shown in FIG. 3, the number of lower setting icons associated with each item icon is, for example, two for color setting, printing direction setting, and double-sided setting, and five for the largest paper size setting. Less than 20.

For this reason, when the target icon is found, the scrolling of the display screen can be reduced by the small number of icons. Therefore, the user can enlarge the display magnification by keeping the entire icon from the beginning. This is because the operation load can be reduced.
On the other hand, the item icon array 20 may be displayed so that only one icon is displayed as a whole from the beginning, but in this case, the icons displayed on the screen with the enlarged display magnification are displayed. Since the number decreases, in the case of the item icon array 20 that originally has a large number of icons, there is a high possibility that the scroll operation for finding the target icon increases, resulting in an increase in operation load.

  Therefore, in the present embodiment, when the lower setting icon array is displayed, only one icon is displayed as a whole from the beginning. Then, the control unit 10 temporarily selects one icon that displays the whole, and the display magnification is reduced to a value that is less than or equal to a predetermined value (two or more (from one) icons that are displayed as a whole by reduction). The following is determined), and it is determined that the temporarily selected icon is finally selected by the user.

FIG. 12 is a subroutine showing the contents of the “setting icon selection process” in step S12 of FIG.
As shown in the figure, the control unit 10 temporarily selects one setting icon that is displayed as a whole, and sets the setting content of the setting icon in the storage area α of the RAM 103 (step S51).

Next, when the mobile terminal 1 is tilted in the left-right direction (step S52: Yes), the display screen scroll process B is performed (step S53). Otherwise, when the mobile terminal 1 moves in the vertical direction, the display magnification is Enlargement / reduction processing is performed (step S54).
(3-2-1) Display Screen Scroll Processing The display screen scroll processing B is a direction in which one icon displayed as a whole tilts (left) every time a rotational movement of the mobile terminal 1 tilted in the left-right direction is detected. Or it is configured to scroll to switch to the icon next to the right). This is different from the display screen scrolling process A (see FIG. 10).

Here, “every time the tilting rotational movement is detected” of the mobile terminal 1 means every time the user tilts the mobile terminal 1 and returns it.
Since it is difficult to see the screen with the mobile terminal 1 tilted, it is considered that the user performs an operation of returning the tilt to the original state so that the screen can be easily viewed after the mobile terminal 1 is tilted. The operation of tilting the portable terminal 1 and the operation of returning it to the original are regarded as a series of operations and controlled (details will be described later).

FIG. 13 is a subroutine showing the contents of the “display screen scrolling process B”.
As shown in the figure, when the mobile terminal 1 moves in a direction tilting to the left (step S61: Yes), if the display screen does not reach the right end of the scrollable range (step S62: No), the control unit 10 By scrolling the screen to the left, the setting icon displayed as a whole is switched (step S63).

Thereafter, waiting for completion of the returning operation for returning the tilt of the mobile terminal 1 (the operation for returning the mobile terminal 1 to the horizontal direction by tilting the mobile terminal 1 in the direction opposite to the initial tilt direction from the horizontal state) (Step S66: Yes). ), The process returns to FIG.
Thereby, the tilt of the tilted mobile terminal 1 can be restored without scrolling the display screen. That is, when the tilt of the mobile terminal 1 is returned, the setting icon displayed as a whole is prevented from returning to the icon before switching.

Note that the control unit 10 determines that the return operation is completed by detecting a rotational movement that returns only the same angle to the side opposite to the direction of the inclination detected before the detection result of the triaxial acceleration sensor 13.
When the mobile terminal 1 moves to the right (step S61: No), if the display screen does not reach the left end of the scrollable range (step S64: No), by scrolling the screen to the right side, The setting icon displayed as a whole is switched (step S65).

Thereafter, as described above, the process returns to FIG. 12 after the completion of the return operation for returning the tilt of the mobile terminal 1 to the original state (step S66: Yes).
For example, when the mobile terminal 1 is rotated from the state shown in FIG. 14A to the left and returned to the original position, the display screen is scrolled to the left as shown in FIG. 14B. The setting icon displayed as a whole is switched from the setting icon 2d2 of A4 size to the setting icon 2d3 of A5 size on the right side.

  If the mobile terminal 1 is further rotated so that the mobile terminal 1 is tilted to the left and returned to the original position, the display screen is scrolled to the left as shown in FIG. , The setting icon 2d3 for the A5 size is further switched to the setting icon 2d4 for the B4 size on the right side. In addition, when it is rotated to the right and tilted back from the state of FIG. 14B, it returns to the state of FIG.

The above is the display screen scrolling process B.
(3-2-2) Display Magnification Reduction Process and Selection Icon Confirmation Returning to FIG. 12, the “display magnification enlargement / reduction process” in step S54 is a display magnification enlargement / reduction process (step S54). The content is the same as that shown in FIG. Here, since only one icon is displayed from the beginning, the main process is basically to reduce the display magnification.

  When the display magnification is reduced in step S54 and the number of icons displayed as a whole is changed from one to two (step S55: Yes), the control unit 10 temporarily sets the setting in step S51. It is determined that the icon has been finally selected by the user, and the setting icon is determined (step S56). Then, the printing condition stored in the printing condition storage unit 105 is changed with the setting content set in the storage area α in step S51 (step S57).

Here, the determination as to whether the number of icons displayed as a whole has changed from one to two or more can be made as follows.
As described above, the control unit 10 determines whether or not the entire icon is displayed in the icon display area 40b from the address information of the four corners of the icon image on the VRAM 116 and the address information of the portion H displayed in the icon display area 40b. Therefore, for example, when the display magnification is reduced in the above step S54, the count number (n1) of the icons before the reduction is reduced and the reduction is performed. If the count number (n2) of the icons that will be displayed later is stored, and n1 and n2 satisfy the formula n2> n1 = 1, one to two or more icons that are displayed as a whole are displayed. It is determined that

  For example, as shown in FIG. 15A, when only the B4 size setting icon 2d4 is displayed and temporarily selected, the mobile terminal 1 is moved in a direction away from the user, as shown in FIG. 15B. Thus, the display magnification is reduced, and the entire two setting icons 2d4 and 2d5 of B4 and B5 sizes are displayed. At this time, the setting icon 2d4 provisionally selected in advance is confirmed, and the printing conditions are changed as described above.

Thereafter, returning to FIG. 7, since the setting icon selected in step S13 is confirmed (Yes), the control unit 10 displays the upper-level item icon array 20 on the screen as shown in FIG. 15C. (Step S14), the flag F is set to 1 (Step S15).
If the selected setting icon is not confirmed (step S13: No), steps S14 and S15 are skipped.

In this case, it is desirable to display the changed setting contents on the paper size icon 2d on the screen so that the user can confirm the changed contents (see FIG. 15C).
According to the mobile terminal 1 configured as described above, in the item icon selection process, the mobile terminal 1 is moved in the left-right direction to scroll the display screen to display the target icon at the center position of the screen, and then the mobile terminal 1 If 1 is moved in the direction perpendicular to the screen (direction closer to the user) to enlarge the display magnification and the display screen has only one icon displayed as a whole, it is determined that the one icon has been selected. Is done. Further, in the setting icon selection process, the mobile terminal 1 is tilted in the left-right direction and rotated to scroll the display screen to display the target icon at the center position of the screen, and then the mobile terminal 1 is perpendicular to the screen. In one direction (away from the user) to reduce the display magnification, and if one or more icons are displayed in the display screen, the one icon is finally selected. It is determined that Accordingly, it is not necessary to perform a tap operation, and an icon can be selected with only one hand, so that an error due to the tap operation can be eliminated, and an icon selection input operation can be easily performed with one hand.

  In the present embodiment, movement of the mobile terminal 1 in the left direction or right direction is “movement in the first direction”, and movement in the direction in which the mobile terminal 1 is brought closer to the user (direction perpendicular to the screen) is “second”. Movement in the direction of ". Further, the rotational movement that tilts the mobile terminal 1 leftward or rightward is “movement in the third direction”, and movement in the direction away from the user (direction perpendicular to the screen) is “ “Movement in the fourth direction”.

  In the present embodiment, the display panel 111 functions as a display unit that displays at least some of the plurality of icons. In addition, the control unit 10 and the three-axis acceleration sensor 13 move the mobile terminal 1 main body in the first direction, the second direction, the third direction, and the fourth direction. Functions as first, second, third and fourth movement detecting means for detecting the movements respectively.

Further, when the control unit 10 executes display screen scrolling processing and display magnification enlargement / reduction processing (each step in FIGS. 8 and 9) based on the detection result of the three-axis acceleration sensor 13, It functions as a display control means in the invention. In addition, when the control unit 10 displays only one icon that is displayed entirely on the display screen due to enlargement of the display magnification during the printing condition setting process, the one icon is a user (operator). When it is determined that it is selected by (when the corresponding step of FIG. 7 is executed), it functions as the determination means in the present invention.
<Second Embodiment>
In the second embodiment, the display magnification enlargement / reduction control is performed when a rotational movement in which the portable terminal 1 is tilted back and forth is detected. This is different from the first embodiment in which display magnification enlargement / reduction control is performed when the movement (parallel movement) of the screen of the mobile terminal 1 in the vertical direction is detected.

Since other configurations are basically the same as those of the mobile terminal 1 of the first embodiment, the same configurations are denoted by the same reference numerals, and description thereof is omitted.
FIGS. 16A and 16B are diagrams for explaining the relationship between the rotation operation of tilting the portable terminal 1 back and forth and the display magnification enlargement / reduction control.
As shown in FIG. 16A, when the portable terminal 1 is tilted forward (arrow K1), the control unit 10 enlarges the display magnification in accordance with the tilt amount (rotation angle) of the portable terminal 1, For example, the area enclosed by the broken line is zoomed in.

Conversely, as shown in FIG. 16B, when the portable terminal 1 is tilted backward (arrow K2), the control unit 10 reduces the display magnification according to the tilt amount and zooms out.
FIG. 17 is a subroutine showing the contents of “display magnification enlargement / reduction processing” of the present embodiment. This process is performed as a subroutine of the item icon selection process of FIG. 9 and the setting icon selection process of FIG. 12 as in the first embodiment.

  As shown in the figure, when the moving direction of the mobile terminal 1 is a direction tilted toward the front (step S111: Yes), the control unit 10 does not have only one icon displayed as a whole (step S112: No). ) The display magnification of the icon display area 40b is enlarged according to the amount of inclination obtained from the detection result of the three-axis acceleration sensor (step S113). If there is only one icon displayed as a whole (step S112: Yes), step S113 is skipped.

The control unit 10 repeats the above steps S112 and S113 while detecting the rotational movement tilted in front of the mobile terminal 1 (step S114: Yes).
After the rotational movement tilting in front of the mobile terminal 1 is no longer detected (step S114: No), the mobile terminal 1 waits for the completion of the returning operation to return the tilt of the mobile terminal 1 (step S118: Yes), and FIG. Returning to FIG.

  On the other hand, when the moving direction of the mobile terminal 1 is a direction inclined backward (step S111: No), the size of the displayed icon is not the lower limit value (step S115: No), and is obtained from the detection result of the triaxial acceleration sensor. The display magnification of the icon display area 40b is reduced according to the tilt amount (step S116). If the icon size is the lower limit (step S115: Yes), step S116 is skipped.

Then, the steps S115 and S116 are repeated while the rotational movement tilting behind the portable terminal 1 is detected (step S117: Yes).
After the rotational movement tilting backward of the mobile terminal 1 is no longer detected (step S117: No), the mobile terminal 1 waits for the completion of the returning operation to restore the tilt of the mobile terminal 1 (step S118: Yes), and FIG. Returning to FIG.

Further, in the present embodiment, the contents of steps S6 and S11 in FIG. 7 are changed as follows (the inside of “” indicates the changed portion).
In step S6, instead of determining whether or not movement of the mobile terminal 1 in the “perpendicular to the screen” or the left-right direction is detected, the mobile terminal 1 “rotational movement tilted in the front-rear direction” or in the left-right direction It is configured to determine whether or not movement is detected.

In step S11, instead of determining whether “moving in the direction perpendicular to the screen” of the mobile terminal 1 or rotational movement tilting in the horizontal direction is detected, “rotating movement tilting in the front-rear direction” of the mobile terminal 1 or It is set as the structure which determines whether the rotational movement tilted to a horizontal direction was detected.
Also in the present embodiment, the mobile terminal 1 can be moved to control the scrolling of the display screen and the enlargement / reduction of the display magnification. In the item icon selection process, the icon displayed as a whole on the display screen is set to 1. If one icon is selected, it is determined that the one icon has been selected. In the setting icon selection process, if one to two or more icons are displayed in the display screen, the one icon is finally selected. It is determined to have been performed.

Therefore, as in the first embodiment, it is not necessary to perform the tap operation, and the icon can be selected with only one hand, so that the mistake due to the tap operation can be eliminated, and the icon selection input operation is easy with one hand. Will be able to do.
In the present embodiment, the movement of the mobile terminal 1 in the left direction or the right direction is “movement in the first direction”, and the rotational movement in which the mobile terminal 1 is tilted forward is “movement in the second direction”. The rotational movement that tilts or tilts to the right is “movement in the third direction”, and the rotational movement that tilts the mobile terminal 1 backward is “movement in the fourth direction”.
<Third Embodiment>
The third embodiment is different from the first embodiment in that a lower setting icon array is pop-up displayed on a screen on which upper item icons are displayed.

Since other configurations are basically the same as those of the mobile terminal 1 of the first embodiment, the same configurations are denoted by the same reference numerals, and description thereof is omitted.
FIG. 18A is a diagram showing an example of a pop-up screen displayed when the paper size icon 2d is selected.
As shown in the figure, the pop-up screen 50 has lower setting icons 2d1 to 2d5 arranged in the vertical direction (Y-axis direction) of the display panel 111, and pops up beside the paper size icon 2d in the icon display area 40b. It is displayed.

In the icon display area 40b, a cursor 51 pointing to one setting icon from the pop-up screen 50 is displayed.
In this Embodiment, the control part 10 is comprised so that the movement of the cursor 51 according to the movement to the vertical direction (Y-axis direction) of the portable terminal 1 can be controlled, and the commanded icon can be switched. Then, after moving the mobile terminal 1 in the vertical direction and pointing the target setting icon with the cursor 51, the mobile terminal 1 is moved away from the user to reduce the display magnification, and the pop-up screen 50 is closed. Assuming that the setting icon indicated by the cursor 51 is finally selected by the user if the display magnification becomes equal to or less than two items icons displayed on the display screen as a whole. Also, with this determination, the pop-up screen is closed (see FIG. 18B).

Also in the present embodiment, as in the first embodiment, it is not necessary to perform a tap operation, and an icon can be selected with only one hand, so that an error caused by a tap operation can be eliminated, and an icon can be performed with one hand. Selection input operations can be easily performed.
In the present embodiment, movement in the direction in which the mobile terminal 1 is brought closer to the user (direction perpendicular to the screen) is “movement in the second direction”, and movement of the mobile terminal 1 in the vertical direction upward or downward is “third”. The movement in the direction away from the user ”and the movement in the direction away from the user (direction perpendicular to the screen) are“ movement in the fourth direction ”. Although explanation is omitted, “movement in the first direction” of the mobile terminal 1 is movement in the left-right direction as in the first embodiment.

<Modification>
The present invention is not limited to the above-described embodiment, and the following modifications can be considered.
(1) In the above embodiment, the configuration in which the icons are arranged in a horizontal row or a vertical row on the printing condition setting screen 40 is shown. However, the present invention is not limited to this, and a configuration in which the icons are arranged in a vertical and horizontal matrix may be used. .

In this case, when the movement of the mobile terminal 1 in the X-axis direction is detected from the detection result of the triaxial acceleration sensor 13, the display screen is scrolled in the left-right direction, and the movement in the Y-axis direction is detected. May be configured to scroll in the vertical direction.
(2) In the above embodiment, the configuration in which the display magnification is enlarged / reduced to zoom in / out around the center of the icon display area 40b has been described, but the present invention is not limited to this.

For example, the position slightly deviated from the center of the icon display area 40b or the position of the end may be used as the center.
(3) In the above-described embodiment, the scrolling is stopped when the end of the scrollable range is reached by scrolling the display screen. However, the present invention is not limited to this.
For example, the icon arrangement may be regarded as a loop arrangement, and icons may be cyclically displayed by scrolling the display screen.

Specifically, the item icon array 20 shown in FIG. 4C will be described as an example. In the right-side scroll, the leftmost icon 2i is displayed after the leftmost icon 2a is displayed. In reverse left scrolling, the leftmost icon 2a can be displayed after the rightmost icon 2i is displayed.
In this case, there is an advantage that it is possible to easily return to the first icon after confirming the arranged icons.

(4) In the above embodiment, the configuration using the three-axis acceleration sensor 13 to detect the rotational movement in which the mobile terminal 1 is tilted in the left-right direction and the rotational movement in which the portable terminal 1 is tilted in the front-rear direction has been described. is not.
For example, the rotational movement can be detected using a known gyro sensor that detects an angle or an angular velocity that rotates around the X-axis direction or the Y-axis direction.

(5) In the above-described embodiment, the configuration in which a target icon is selected from a two-level hierarchical structure in which one or more setting icons are provided below each item icon has been described. However, the present invention is limited to this. It is not a thing.
The present invention can be applied even if the hierarchical structure of the icons may be three or four or more, and even if the icon has a flat structure without a hierarchy.

(6) In the above embodiment, the display screen scrolling control is different between the item icon selection process and the setting icon selection process (display screen scrolling processes A and B). It is not limited.
For example, in the first embodiment, the display screen scrolling control in the setting icon selection process may be performed by detecting the movement of the mobile terminal 1 in the left-right direction, similarly to the item icon selection process. Absent. Further, in the second embodiment, the display screen scrolling control in the item icon selection process is performed by detecting the rotational movement of the portable terminal 1 tilted in the left-right direction, similarly to the setting icon selection process. It doesn't matter.

(7) In the above embodiment, the mobile terminal 1 is scrolled to the right when the mobile terminal 1 is tilted to the right, and the display screen is scrolled to the left when the mobile terminal 1 is tilted to the left. Although the configuration in which the tilt direction of the terminal 1 matches the scroll direction is shown, the present invention is not limited to this. The mobile terminal 1 may be configured to scroll in a direction opposite to the tilt direction of the mobile terminal 1.
(8) In the above-described embodiment, when the setting icon array of the lower hierarchy is displayed, the configuration in which the display magnification is enlarged and displayed so that the whole icon is displayed from the beginning is shown. However, the present invention is not limited to this.

For example, if the number of icons in the lower hierarchy is relatively large, the entire screen is displayed on the display screen in the same way as the initial screen of the upper item icon arrangement from the viewpoint of easy finding of the target icon and reduction of scrolling operations. It is desirable that there are a plurality of icons for displaying.
(9) In the above embodiment, an example of selecting an icon for setting printing conditions has been described. However, the present invention is not limited to this.

For example, music files are usually categorized by genre and artist and managed in layers, and in order to listen to the desired music, it is necessary to select icons at each level. The present invention can be applied effectively when it can only be operated with one hand, such as when it is held by a strap or holding a bag.
The present invention can also be applied when selecting an icon on the menu screen after the mobile terminal 1 is activated.

Further, for example, in the case where the multifunction device 200 (see FIG. 1) is provided with a portable dedicated operation panel for performing copy settings, fax settings, scan settings, etc., various types of icons can be selected by selecting icons on the dedicated operation panel. The present invention can be applied to the setting screen.
(10) In the third embodiment, the pop-up screen 50 is configured with the setting icons arranged in the vertical direction (Y-axis direction). However, the configuration is not limited to this, and the setting icons are displayed in the horizontal direction. You may arrange in (X-axis direction). In this case, similar to the first embodiment, the cursor 51 can be moved by rotating the mobile terminal 1 while tilting it in the left-right direction for a moment.

(11) In the above embodiment, a rectangular icon is displayed on the printing condition setting screen 40. However, the shape of the icon is not limited to this, and may be a polygon such as a triangle or a pentagon, or a circle. .
(12) In the above embodiment, the configuration using the display panel 111 in which the LCD 113 and the touch panel 114 are stacked as the display means for displaying at least a part of the plurality of icons is shown. However, the present invention is not limited to this.

For example, an organic EL panel (organic electroluminescence panel) may be used instead of the LCD panel.
Further, the touch panel 114 may not be stacked. In this case, by replacing the print start button 41 and the reset button 42 with hard keys, the print start and the print conditions can be reset as in the above embodiment. Further, for example, the print start button 41 and the reset button 42 may be displayed side by side in the icon array of the icon display area 40b so that they can be selected.

  The arrangement positions of such print start buttons and reset buttons are not particularly limited, and it is desirable to set the arrangement positions so as not to impair operability in accordance with the specifications of the mobile terminal. Also, for example, as in the above embodiment, when the print start button and the reset button are configured with soft keys on the display screen, when the user operates the mobile terminal with the right hand, when operating with the left hand, You may comprise so that an arrangement position can be changed. In this case, there is an advantage that operability can be improved with both the right hand and the left hand.

(13) If the display panel 111 with the touch panel 114 incorporated is used as in the above embodiment, for example, when the item icon or the setting icon is tapped with a finger during the print condition setting process In addition, icon selection by the tap may be accepted.
(14) In the above embodiment, the configuration in which the mobile terminal 1 and the multifunction device 200 are connected by wireless communication using Bluetooth (registered trademark) is shown, but the present invention is not limited to this.

For example, it may be configured to connect via wireless communication using infrared rays or a wireless LAN such as WiFi.
In addition, a wired connection such as a USB cable or a LAN cable may be used. Even in this case, since the user can move the portable terminal 1 held with one hand, the portable terminal 1 configured as described above can be selected by moving the portable terminal 1 without performing a tap operation.
