Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a fish finder, and particularly relates to a fish finder that has an easy-to-understand display for operating instructions [Prior Art] As devices become more multi-functional, menu display methods that display operating methods on a display have become widely adopted. The display menu takes the form of selection branches,
It is known that items that can be selected at each level are displayed each time.

[Problems to be Solved by the Invention] However, the conventional display menu has the following problems.

Only a large number of items are listed.

The current settings cannot be easily determined.

I don't know how many types of options there are.

One-sided hierarchical menus are complicated to operate.

Due to the above-mentioned problems, ++] gave the impression that it was difficult for users to get used to it.

The present invention was made to eliminate such problems, and it is an object of the present invention to provide a fish finder with an easy-to-understand menu display and improved operability of the device.

[Means for Solving the Problems] The present invention provides a fish finder in which each menu displayed on a display is selected based on a program by operating each key on an operation panel. When one of the menu items in a certain hierarchy is selected by moving the cursor, the item in the next hierarchy corresponding to the selected item is displayed while the menu in the hierarchy and the set cursor are displayed.

[Embodiment] FIG. 1 is a block diagram showing an embodiment of the fish finder of the present invention.

1 is a CPU (central processing unit) that centrally controls the fish finder, 2 is a ROM (read only memory) that stores the CPU control program, and also has a memory for displaying kanji characters. ing. 3 is a RAM (random access memory), which stores data from the CPU 1 as needed and also stores various setting data described below. 4', "call" key 4a, "setting" key 4b.

It is an operation panel equipped with a "△" key 4c, a "" key 4d, etc., and information set with the various keys is taken into the CPUI via the input/output section 5. Reference numeral 6 denotes an image memory, which stores screen data to be displayed on the display 7.

FIG. 2 shows a menu display on the display of the fish finder.

An example of menu display will be described below based on the flowchart of FIG. 3.

When any key on the 11i panel 4 is pressed, the process proceeds from step S1 to step S2, in which it is determined whether the pressed key is the "call" key 4a that calls the menu,
If the pressed key is not the call key 4a, a predetermined process corresponding to the pressed key is performed in step S3, but if the pressed key is the call key 4a, the process advances from step S2 to step S4, and the process shown in FIG. A main menu 100 as a first hierarchy is displayed on the illustrated display 7, and operation guidance required for the following menu operations is displayed on the right side display section of the main menu 100. The display on the display 7 is easy to read because it is displayed in Chinese characters as shown.

In the main menu 100, the diagonally shaded area is a reverse display in which the displayed characters and their background are reversed, and the line 100a surrounding the item is a cursor, and this cursor 100a is the main menu When is displayed for the first time, it is displayed for the first item, “transmission/reception unit °,” but in FIG. 1, the “” key 4d is pressed in step S5.
The state is shown in which the cursor 100a is moved to the "oblique angle degree" item by pressing .Thereafter, in step S6, it is determined whether or not the "setting" key 4b has been pressed.The setting key 4
When b is pressed, it is determined in step S7 whether the operation of the main menu is finished, that is, whether the cursor 100a at this time is on the "menu end" item.If the menu is ended, step S7 Proceeding to step S8, the main menu operation is completed, and the main menu! The display of OO is erased and the process returns to the original step Sl.

Since the "call" key 4a has an on/off function, the main menu operation can also be ended by pressing the call key 4a again during the main menu operation.

On the other hand, if the main menu is not finished, the process advances from step S7 to step S9, and the submenu 200 corresponding to the item selected with the cursor 100a is displayed as the next level in the lower display part of the main menu 100, The setting value 250 set in advance or last time is displayed for each item of the submenu: L-200. In this submenu 200 as well, the cursor 200a is initially displayed for the first item. 1△”, “” after that
and “Settings” key operations target the sub menu.

If you want to change the setting value 250 displayed for each item by operating the "△" or "" key in step S10, or if you want to return to the main menu lOO without changing each item in the sub menu 200, When the cursor 200a is moved to each corresponding item and the setting key 4b is pressed, the process advances from step Stt to step S12. Step S12
Now, if the set item is "Return to main menu", proceed to step S13 to return to sub-menu: L-2.
00 and the set value 2 to 50 are erased, and then the process returns to step S5 to wait for key input after the main menu 100 is displayed.

On the other hand, if you select an item other than "Return to main menu", such as "Step Angle", step S
12, the process advances to step S14, and a setting value menu 300 corresponding to the item "step angle" is displayed. The display items in this setting value menu 300 are displayed in two vertical columns, up to a maximum of 16 items, and at the end of the displayed items, two items, "Return to sub menu" and "Return to main menu" are always displayed. It is now possible to do so.

In step S15, after moving the cursor 300a to a predetermined item by operating the "△" or "" keys 4c, 4d, and pressing the setting key, steps S16 to S17 and S1
8, the item selected with the cursor 300a is “
It is determined whether it is "return to the sub menu" or "return to the first main menu". This time, since I selected another item, I passed through step S17゜SlB and went through step S19.
, the numerical value of the item selected with the cursor 300a is taken into the CPU, the previously set numerical value is changed, and in step S20, the sub menu 2
The display of the set value "l" of the "step angle" in 00 is rewritten to the changed value. After that, step S1
5 and will be waiting for key personnel.

Next, for example, in the sub menu 200, “3 right chest”
If you want to change the value "15°" set for the item, move the cursor 300a to the item "Return to submenu" and press the setting key 4b (this allows you to move from step SlB to Proceeding to step S21, the display of the setting value menu 300 is erased, and the process returns to step SIO after displaying the sub menu 200 and the setting values 250.

On the other hand, when the change work for each item of the sub menu 200 is completed, the cursor 300 of the setting value menu 300 is
All you have to do is move a to the "Return to main menu" item and press the setting key 4b, which will take you from step S17 to step S22. Proceed to S23 and set value menu 300
Then, the display of the sub-menu 200 and the setting value 250 is erased, and the process returns to step S25 after the main menu is displayed. Thereafter, by moving the cursor 100a in the main menu 100, it is possible to change setting values for other items or to finish the work in the main menu.

Note that even if the sub menu 200 is displayed, the main menu 10
0 is displayed as is, and even if the setting value menu 300 is displayed, the main menu 100. The sub menu 200 and setting values 250 are displayed as they are, and the cursor 10
0a and 200a are displayed as they are, for example, as shown in FIG. It is easy to know. Furthermore, since the surface hierarchy menu is displayed, for example, once the change setting of "step angle" is completed, it is possible to know at a glance what kind of item should be changed next.

FIG. 4 is a block diagram showing another embodiment of the present invention, and the difference from the block diagram of FIG. 1 is that the operation panel 4°
is provided with keys 4e to 4h for four directions, and
As shown in FIG. 5, various menus are also displayed in the lower part 7B of the echo image from the fish school and the seabed, which is displayed in the upper part 7A of the display 7.

The menu display on the display section 7B will be explained below.

If the call key 4a on the operation panel 4° shown in FIG. 4 is not pressed,
