[4-1] Description of Conventional Control Method

First, a conventional control method will be described.

FIG. 5 shows a control method for the entire tree structure of various setting screens.

In FIG. 2, one setting screen (top menu) of the first layer and one setting screen (submenu) of the second layer
, There are 20 setting screens of the third layer, and there are a total of 27 setting screens.

Each setting screen is given a two-digit screen ID. The top menu of the first layer is provided with ID “0”. Each submenu of the second layer has ID "
IDs "1" to "6" are assigned to the setting screens of the third layer, and IDs "11" to "62" are assigned to the respective setting screens.

The tens place of the ID of each setting screen of the third layer indicates the ID of the submenu at a higher level. The first digit of the ID of each setting screen of the third layer indicates the number of a selection item in a sub-menu at a higher level. Therefore, ID “6”
The setting screen of “2” indicates that the screen is displayed when the second selection item of the submenu of ID “6” is selected.

Control software exists for each screen ID (each setting screen). As described in the top menu, each control software includes an initial setting unit A for displaying an initial state screen, and a control unit B for performing a process according to a key input on the setting screen.

The control software for the entire tree structure of the various setting screens includes 27 control softwares 101 to 127 corresponding to the 27 setting screens and an MA for managing these control softwares.
And an IN unit 100.

The initial setting section A in the control software 102 to 127 for the setting screen of the second layer and the setting screen of the third layer
Is activated by a command from the control unit B in the control software 101 to 127 for another setting screen.

The designated initial setting unit A displays the initial state screen of the corresponding setting screen, and stores the screen ID of the control software including the initial setting unit A in the screen ID holding unit 1.
Write to 10.

Thereafter, when a key input is performed (step 31), the MAIN unit 100 reads the screen ID held in the screen ID holding unit 110 (step 32), and performs control corresponding to the read screen ID. The key information input by the key is passed to the control unit B in the software (step 33), and the corresponding process is performed by the control unit B to enter a key input standby state.

For example, when the control unit B in the control software 101 of the screen of ID “0” (top menu) switches the screen to the screen of ID “1” (submenu),
The initial setting unit A in the control software of the screen with the ID “1” is activated. The screen is changed by the initial setting unit A and the ID in the ID holding unit 110 is changed.

FIG. 6 shows a control method of the MAIN unit 100.

When a key input is performed (step 4
1) The type of the input key is determined (step 4)
2). If the input key is not a preset key (NO in step 43), the screen ID holding unit 11
Read the screen ID held at 0 (step 4
4) The key information input by the key is transferred to the control unit B in the control software corresponding to the read screen ID (step 45), and the control unit B performs the corresponding process to enter a key input standby state.

If it is determined in step 43 that the input key is a preset key, the screen ID assigned to the preset key is read from the nonvolatile memory 21 (step 46). If the read screen ID is not valid (NO in step 47), the apparatus enters a key input standby state. If the read screen ID is valid (YES in step 47), the CPU 101 activates the initial setting unit A in the control software corresponding to the screen ID, and writes the screen ID in the screen ID holding unit 110 (step 47). 48).

Therefore, for example, if the screen ID “62” is assigned to a certain preset key and this preset key is pressed, the setting screen corresponding to the drawing ID “62” is immediately displayed. . Drawing I
The control after the setting screen corresponding to D "62" is displayed is the same as the conventional one.

As a method of registering the screen ID to the preset key, for example, when the setting screen corresponding to the screen ID to be registered is displayed, the preset key is pressed. When a preset key is pressed and no screen ID is registered for that preset key,
The screen ID of the setting screen currently displayed in association with the data representing the preset key is registered in the nonvolatile memory 21. At this time, it is preferable that the user be notified by a beep sound or a screen message that the screen ID has been assigned to the preset key.

As a method of deleting a screen ID already assigned to a predetermined preset key, for example, when the preset key is kept pressed for a predetermined time or more, the screen ID assigned to the preset key is deleted. There is such a method. At this time, it is preferable that the user be notified by a beep or a screen message that the screen ID to the preset key has been deleted.
