<Description of Operation of Image Forming Apparatus>
Next, the operation of the image forming apparatus 1 will be described. Here, the first embodiment will be described as an operation of the image forming apparatus 1 first.

[First Embodiment]
FIG. 4 is a flowchart showing the operation of the image forming apparatus 1 in the first embodiment.
FIGS. 5A to 5H are views showing the state of the user interface 300 in the first embodiment.

  First, the operation control unit 903 determines whether a print job has been received via the information communication unit 904 (step 101).

  If a print job has not been received (No in step 101), the operation control unit 903 turns on the home button in a normal color (for example, blue) (step 102). This is the state shown in FIG. 5A and notifies the user that a normal operation is performed when the home button is pressed.

Next, the operation control unit 903 determines whether or not the user has pressed the home button (step 103). This can be determined based on whether or not the user instruction receiving unit 901 has acquired transition information from the home button.
As a result, when the user has not pressed the home button (No in Step 103), the process returns to Step 101.

  On the other hand, when the user presses the home button (Yes in Step 103), the operation control unit 903 displays an initial screen on the touch panel 310 of the user interface 300 (Step 104). This is, for example, the screen shown in FIG. This initial screen is also called a home screen, and is a screen on which the user can select the operation of the image forming apparatus 1. Here, the user can select each operation such as Copy (copy), Fax (facsimile), and Scan (scan).

  On the other hand, when a print job is received (Yes in step 101), the operation control unit 903 operates the image recording apparatus 200 to form an image on a sheet (step 105). Further, the operation control unit 903 causes the home button to blink in a color (for example, red) different from the normal button (step 106). This is the state shown in FIG. 5 (c), and when the user presses the home button, the user does not move to the initial screen, which is a normal operation, but performs other operations. It is a notification. At this time, as shown in FIG. 5C, “job execution” may be displayed on the touch panel 310.

Next, the operation control unit 903 determines whether or not the user has pressed the home button (step 107).
As a result, if the user has not pressed the home button (No in Step 107), the process returns to Step 101.

On the other hand, when the user presses the home button (Yes in Step 107), the state acquisition unit 902 acquires a state change of the image forming apparatus 1 (Step 108).
Then, the operation control unit 903 executes an operation other than the normal operation in accordance with the state change acquired by the state acquisition unit 902 (step 109).

  As another operation, for example, when a print job is being executed as a state change and there is no other state change, the operation control unit 903 cancels the print job (stops image formation).

The home button is a hardware key in the above-described example, but may be a software key. The home button is displayed on the touch panel 310 even in the case of a software key, and is unlikely to disappear in a normal state. Therefore, the user can usually operate the home button when any screen is displayed. In the present embodiment, the function of such a home button is changed according to the operating state of the image forming apparatus 1. For example, when the image forming apparatus 1 is forming an image, the function of the home button is changed from the function of transitioning to the initial screen to the function of canceling image formation as another operation. That is, an operation desired by the user is given to the home button according to the operation state of the image forming apparatus 1. As a result, the user can realize a desired operation according to the operation state of the image forming apparatus 1 by pressing the home button.
As a result, when the home button is a hardware key, the number of buttons can be reduced. When the home button is a software key, it is displayed in a normal state, so there is no need to display another button that requires an extra display area. Therefore, the number of operation buttons displayed on the display screen can be reduced. Furthermore, it is not necessary to give an exclusive instruction.

  In this case, the user can use the home button as a so-called shortcut key, and the operability for the user is further improved. That is, it is possible to satisfy both the reduction of operation buttons such as software keys and hardware keys and the convenience of the user. Further, the pop-up screen can be displayed as in the second embodiment, or the operation can be changed by the difference in the operation of the home button as in the third embodiment, and the operability for the user is further improved. Further, as in the fourth embodiment, even when the display screen shifts to another service screen, when the image forming apparatus 1 is forming an image, the function of the home button is maintained and the image formation is stopped. By maintaining the function of performing the operation, the operability for the user is unlikely to deteriorate.

In the example described in detail above, the home button has been described as an example of the initial screen transition means, but the present invention is not limited to this as long as it can be displayed and operated in a normal state. For example, it may be a menu button or the like.
In the above-described example, the case where a function for canceling image formation is added to the home button as another operation has been described. However, the present invention is not limited to this. A function of performing an operation other than the operation of stopping the image formation may be provided. The user may be able to set in advance. For example, the received facsimile print function, transfer function, or toner remaining amount display function may be selected. Alternatively, the operation control unit 903 may determine another operation according to a predetermined priority. Further, the priority may be set by the user.

  The device having the functions of the touch panel 310 and the control device 900 described above can also be regarded as a display device. In this case, the present invention is not limited to application to an image forming apparatus, and can be applied to any apparatus that has a button for returning to the initial screen and a change in the state of the apparatus. Examples of such a device include devices such as a tablet terminal and a smartphone. For example, in a smartphone, it is conceivable to give a plurality of functions to the home button. Specifically, it is conceivable that a function for displaying an initial screen is first given to the home button, and during the call, a function for terminating the call or a function for starting recording is given to the home button as other operations. Also in this case, this button is not limited to the home button, and may be a power key or the like.

Furthermore, the device having the function of the control device 900 described above can also be regarded as a display control device that controls the display screen displayed by the display means.
Further, the home button outputs transition information for transitioning the display screen in the display unit that displays information related to the image forming apparatus 1 as a display screen to a predetermined initial screen by a user input. Depending on the state of the apparatus 1, it is used to change to an operation for transitioning to a screen other than the initial screen or an operation for stopping the image formation of the image forming apparatus 1 instead of the operation for displaying the initial screen on the display means. It can also be understood as an input device characterized by that.
