Description

  The present invention relates to a display panel configured to display an image display based on a plurality of image data stored in a storage unit in a hierarchical definition or order in advance on a touch panel type display unit.

  Conventionally, for example, image forming apparatuses such as copiers, printers, facsimiles, or multifunction machines equipped with these functions are equipped with a liquid crystal display panel that is a touch panel type so that operations such as setting change and function selection can be performed. This is well known.

  On the other hand, in such an image forming apparatus, functions are set / changed by selecting various setting input keys displayed on the display panel and are hierarchically defined in accordance with recent multifunctionalization. There is known a technique for switching and displaying different screens for further setting / changing functions (for example, see Patent Document 1).

  On the other hand, in recent mobile phones and the like, multifunctionalization has progressed, and for example, a large amount of photo data is stored, and the photo data is selected and transmitted as an attached file of an e-mail.

At this time, since a large number of photo data, for example, a large number of photo images displayed on one screen in a thumbnail format, it is difficult to confirm what kind of photo it is. Alternatively, a desired photograph can be selected by sequentially switching and displaying in order of file names by touch panel operation.

  However, in the image forming apparatus configured as described above, for example, when it is desired to return to the previous or second image for confirmation of the setting contents in the hierarchically transitioned display, the return is performed. As for the order, it was forced to be troublesome to go back every screen.

  Similarly, in the above-described mobile phone or the like, when there are a plurality of attachment file candidates, it is not possible to perform operations such as displaying only the candidate images alternately on one screen for confirmation (comparison). It was a fact.

  Therefore, in consideration of the above circumstances, the present invention changes the switching display order depending on the presence / absence of a priority designation operation when a plurality of image data is hierarchically defined or ordered and displayed on a touch panel display unit. An object is to provide a display panel that can improve operability.

  The display panel of the present invention includes a touch panel type display unit, a storage unit in which a plurality of image data corresponding to images displayed on the display unit are hierarchically defined or stored in order, and normally in the storage unit. When the images based on the stored image data are hierarchically defined or ordered and displayed on the display unit, and the images are displayed on the display unit hierarchically or in order, A control circuit that stores the image in the storage unit when the slide operation is performed and displays the image stored in the storage unit on the display unit when the slide operation is performed in the other direction of the display unit; It is characterized by having.

  At this time, the control circuit can store the image in the storage unit when a sliding operation is performed in one of the four directions set in the display unit.

  Further, the control circuit can erase the image stored in the storage unit when a sliding operation is performed in one of the four directions set in the display unit.

  Further, the control circuit, when the slide operation is performed in one of the four directions set in the display unit, has already displayed before the image displayed on the display unit and stores the memory The image stored in the section can be displayed.

  In addition, the control circuit displays the image after the image displayed on the display unit when the slide operation is performed in one of the four directions set on the display unit, and the storage unit. The image stored in can be displayed.

  The predetermined one of the four directions described above is a direction that does not overlap each other.

  The display panel of the present invention can improve operability when a plurality of image data are hierarchically defined or ordered and displayed on a touch panel type display unit.

  Next, a display panel according to an embodiment of the present invention is applied to a display panel mounted on an image forming apparatus and will be described with reference to the drawings.

  FIG. 1 is an explanatory block diagram of an image forming apparatus equipped with a display panel according to an embodiment of the present invention, FIG. 2 is an explanatory diagram of a touch panel operation example on the display panel according to an embodiment of the present invention, and FIG. FIG. 4 is an explanatory diagram of a specific control example by the control circuit mounted on the display panel according to the embodiment of the present invention, FIG. 4 is a flowchart of a control example by the control circuit mounted on the display panel according to the embodiment of FIG. FIG. 5 is an explanatory diagram of another touch panel operation example on the display panel according to the embodiment of the present invention.

  As shown in FIG. 1, an image forming apparatus 1 according to an embodiment of the present invention includes a scanner unit 2 for reading a document used for a copying function, a facsimile function, and the like, a start switch, a numeric keypad, and a mode selection switch. A control program for the entire image forming apparatus 1, including an operation unit 3 having a large number of button switches, a touch panel display unit 4 such as a liquid crystal monitor, and a program that can be set on the operation unit 3 and the display unit 4 ROM 5 storing image data, RAM 6 for temporarily storing image forming processing conditions and the like changed in the operation unit 3 and display unit 4, image data of a document read by the scanner unit 2, a personal computer line not shown, or A large-capacity hard disk drive (HDD) 7 for storing image data transmitted from a facsimile line or the like, and an image stored in the HDD 7 A printing unit 8 to execute the image forming process based on the data, and a, a control circuit 9 for controlling the on the basis of a control program stored in the ROM 5.

  Further, the display unit 4 displays functions (setting screens and the like) as a known image forming apparatus 1 and, as shown in FIG. 2, when the button switch 4a or the like displayed by the touch panel method is pressed, By causing the function of the button switch 4a to be executed by the control circuit 9 and sliding the surface with a finger or the like, for example, by sliding the finger to the left in the drawing, an image in a display state is temporarily stored in the RAM 6 or the HDD 7 And a slide touch switch function of displaying an image already displayed before the image in the display state and temporarily stored in the RAM 6 or HDD 7 by sliding it with a finger or the like to the right in the figure.

  As shown in FIG. 3, the slide touch switch function of the display unit 4 temporarily stores an image in the display state in the RAM 6 or the HDD 7 by sliding it with a finger or the like on the drawing, and moves the lower side of the drawing. The image temporarily stored in the RAM 6 or the HDD 7 is erased by sliding it with a finger or the like, and is already displayed before the image in the display state by sliding it with the finger or the like to the left in the figure. The image temporarily stored in the RAM 6 or the HDD 7 is displayed, and the image that is displayed after the image in the display state by sliding with a finger or the like to the right in the drawing and the image temporarily stored in the RAM 6 or the HDD 7 is displayed (stored). In the case of an image that has not been performed, there is no particular limitation such as “operation of the button switch 4a of“ next ””.

  At this time, erasing the image temporarily stored in the RAM 6 or HDD 7 by sliding with a finger or the like below in the drawing erases the image in the display state when the image with the priority designation operation is in the display state. When an image that has not been subjected to priority designation operation is in the display state, an image that has already been prior designation operation and is in front of the image in the display state may be deleted.

  By the way, in the display of the display unit 4 shown in FIGS. 2 and 3, only the button switch 4a is illustrated as a function button switch for shifting (transitioning) to the next screen as a button function by the display switching control of the present invention. However, the display is not limited to the “next” display as shown in the figure. For example, “execute” or a character display button for selecting a function or mode may be used.

  Next, an example of display switching control by the control circuit 9 will be described with reference to FIG.

(Step S1)
In step S1, for example, the control circuit 9 designates a mode in which a plurality of hierarchically defined image data is displayed in a transitional manner by selecting and setting the panel switch function of the display unit 4 from the display of the main screen or the like. Then, the process proceeds to step S2.

  When a mode that is not defined hierarchically (for example, a simple enlargement / reduction ratio selection screen or a density selection screen) is selected from the display of the main screen or the like, normal display switching is executed. To do. Further, for example, display switching in the tab format is the same.

(Step S2)
In step S2, the control circuit 9 displays the first setting screen such as the designated mode, and proceeds to step S3.

(Step S3)
In step S3, when the setting operation is selected using the touch switch function of the display unit 4, the control circuit 9 proceeds to step S4, and the “next” button switch 4a is selected ( If it has been pressed), the process proceeds to step S5, and if it is slid left by the slide touch switch function, the process proceeds to step S6.

  That is, when the “next” button switch 4a is selected, the control circuit 9 determines that the image has not been subjected to the priority designation operation for the display order that is hierarchically defined or ordered in advance. In addition, when the slide operation is performed to the left by the slide touch switch function, the control circuit 9 determines that the image has been subjected to a priority designation operation with respect to a display order that is hierarchically defined or ordered in advance.

  As a result, when the control circuit 9 is slid to the left by the slide touch switch function, the control circuit 9 changes the display order that is hierarchically defined or ordered in advance.

(Step S4)
In step S4, the control circuit 9 executes the function that has been set using the touch switch function of the display unit 4, and loops to step S3 to wait for the next setting operation.

  Depending on the type of function that has been set, the setting operation is completed and the display on the display unit 4 is changed to the main screen or the like.

(Step S5)
In step S5, the control circuit 9 displays the next screen defined hierarchically on the display unit 4 and proceeds to step S7.

(Step S6)
In step S6, the control circuit 9 stores the selected setting screen in the RAM 6 or the HDD 7 and proceeds to step S5.

(Step S7)
In step S7, when the right sliding operation is performed by the slide touch switch function of the display unit 4, the control circuit 9 proceeds to step S8, and the “next” button switch 4a is selected (pressed). In this case, the process proceeds to step S9, and when the slide operation is performed to the left by the slide touch switch function, the process proceeds to step S10.

  That is, when the “next” button switch 4a is selected, the control circuit 9 determines that the image has not been subjected to the priority designation operation for the display order that is hierarchically defined or ordered in advance. In addition, when the slide operation is performed to the left by the slide touch switch function, the control circuit 9 determines that the image has been subjected to a priority designation operation with respect to a display order that is hierarchically defined or ordered in advance.

  Thus, when the control circuit 9 is slid to the left by the slide touch switch function, the display order that is hierarchically defined or ordered in advance is changed. Change the order anew.

(Step S8)
In step S8, the control circuit 9 displays on the display unit 4 the previous display screen that has been displayed and specified to be stored in the RAM 6 or HDD 7 by the right slide operation using the slide touch switch function of the display unit 4, and then proceeds to step S3. And loop.

(Step S9)
In step S9, the control circuit 9 displays the next screen defined hierarchically on the display unit 4 and loops to step S3.

(Step S10)
In step S10, the control circuit 9 stores the selected setting screen in the RAM 6 or HDD 7 and loops to step S5.

  Thereafter, the control circuit 9 executes any of the routines described above in accordance with the user's operation every time the hierarchy transitions downward.

  Specifically, as shown in FIG. 5, when the “next” button switch 4 a is selected in a state where the setting screen A transitioned from the main screen or the like is displayed, the setting screen is displayed on the display unit 4. A setting screen B which is the next layer of A is displayed.

  In this state, when the slide operation is performed to the left by the slide touch switch function, the setting screen B is stored in the RAM 6 or the HDD 7, and the setting screen C that is the next layer of the setting screen B is displayed on the display unit 4. The

  When the “next” button switch 4 a is selected on the setting screen C, the setting screen B is stored in the RAM 6 or the HDD 7 and the setting screen D that is the next layer of the setting screen C is displayed on the display unit 4. Is displayed.

  From this state, when the slide operation is performed to the left by the slide touch switch function, the setting screen D is stored in the RAM 6 or the HDD 7 in addition to the setting screen B, and the display unit 4 is the next layer of the setting screen D. A setting screen E is displayed.

  Further, when the setting screen E is displayed, if the slide operation is performed to the right by the slide touch switch function, the setting screen immediately before the setting screen E and displayed in the RAM 6 or the HDD 7 is displayed. That is, here, the setting screen D is displayed on the display unit 4.

  In this state (display screen D display), when a slide operation is performed to the right by the slide touch switch function, the setting screen immediately before the setting screen D is displayed and stored in the RAM 6 or the HDD 7, that is, the setting screen D. Here, the setting screen B can be displayed on the display unit 4.

  As described above, in the display panel of the present invention, the image data of the screen necessary for the user's intention can be preferentially stored in the RAM 6 or the HDD 7 and the switching display can be performed without other screens. When the user is at a loss in setting or wants to change to a different setting after operating with a certain setting, a trial setting screen can be quickly displayed on the display unit 4 to perform the changing operation.

  Further, since the display panel of the present invention uses the existing display unit 4, ROM 5, RAM 6 or HDD 7, and control circuit 9 as they are, no dedicated parts are required and the product cost increases. Can be suppressed.

  In the above embodiment, the display panel according to the present invention is applied to the image forming apparatus 1. However, it is needless to say that the present invention can be applied to all display panels including a touch panel type display unit (liquid crystal panel or the like). It is.

  In the above embodiment (FIG. 3), the display unit 4 has four directions, ie, up, down, left, and right (display state standard), and each of the top, bottom, left, and right directions is a predetermined direction that does not overlap, that is, a slide operation direction. The function assigned to each predetermined direction in the upper, lower, left, and right directions is not limited as long as it is not an overlapping direction.
