Abstract

PURPOSE:To facilitate function setting operation by specifying and altering only an altered item by assigning individual addresses to function choices when functions having hierarchical structure that becomes complicated as the functions increases are set. CONSTITUTION:The function setting device has a code information storage part 3 which holds individual address code information on the function choices and a code information discrimination control part 2 which sends a code inputted from a code input means 1 to a display means control part 4 and discriminates whether or not the code is registered in the code information recognition part 3. An address code corresponding to a setting item which is already allocated and a data code corresponding to a setting parameter to be altered can be inputted through the code input means 1, and displayed by a function display means 5 consisting of an LED, etc. The alteration parameter received by the code information discrimination part 2 is processed by a determined code process control part 6 and held by altering a table in a determined code storage part 7.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to function setting by an operator panel provided in a printer or the like, and more particularly,
Input control method for function setting.

[0002]

2. Description of the Related Art In the conventional function setting method, unnecessary item display when changing the function setting is displayed on a display means such as an LED according to the order of a fixed table (for example, JP-A-61). No. 239972). The setting items can be selected by the code only in the same layer (for example, Japanese Patent Laid-Open No. 61-210756).

Here, as a conventional example similar to the latter, FIG.
It will be specifically described with reference to.

The conventional function setting device has a hierarchical structure as shown in FIG. 9, and when changing the function setting, first scan from the first layer until a desired item is displayed on the display panel, By selecting the change item, it transits to the next second layer. Similarly, in the second layer, a change item is displayed and selected to transition to the third layer. When reaching the final data layer, the parameters are changed.

Next, RS4 currently set from FIG.
A procedure for changing the baud rate of 22 from 9600 baud to 4800 baud will be described as an example.

When a function change request is made, the first level "Indysetti" is first displayed on the display panel. Here, select the next "interface" in the same layer. When "Interface" is selected, the display transits to the next second layer and "RS232" is displayed.

Here, the next "RS422" in the same layer is selected. When "RS422" is selected, the display transits to the next third layer and "baud rate" is displayed. Further, when the "baud rate" is selected, the final data layer is displayed, and the changed parameter "9600 baud" is displayed. Now 9600
I want to change the baud to 4800 baud, so the display is "480
The purpose is achieved by changing to "0 baud" and selecting.

[0008]

However, in these conventional function setting methods, when a change item is selected from setting items having a hierarchical structure of n layers, the display means other than the desired item does not need to be displayed. In addition, there is a problem in that operability is difficult because complicated switches must be operated before reaching the lower layer.

Further, even when selecting an item by code input, it is possible to select only in the same layer, and there is a problem that code selection is required n times when selecting an item having n layers.

The present invention has been made in view of the above-mentioned conventional circumstances, and therefore an object of the present invention is to provide a novel function setting device capable of solving the above-mentioned problems inherent in the prior art. To do.

[0011]

In order to achieve the above object, a function setting device according to the present invention holds address code information in consideration of a lower hierarchy especially when selecting a setting item having a hierarchical structure of n layers. It has a code information storage unit, and is provided with a code information identification control unit capable of selecting and changing only parameters of desired setting items.

[0012]

In the present invention, desired setting items can be selected without being aware of the hierarchical structure.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described in detail with reference to the accompanying drawings with reference to the accompanying drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention, FIG. 2 is a block diagram of hardware in an apparatus for implementing the present invention, and FIG. 3 is a system diagram consisting of four layers of setting items and data layers. FIG. 4 is a structure diagram of an address / code structure for selecting a setting item and a data code structure for selecting a setting parameter. FIG. 5 is a diagram showing a display means by four 7-segment LED displays. It is a flowchart which shows the operation | movement flow from input to data finalization.

Referring to FIG. 1, reference numeral 1 is a code input means, 2 is a code input from the code input means 1, is sent to the display means control section 4, and is the code registered in the code information storage section 3? A code information identification control unit for identifying whether or not, 3 is a code information storage unit that holds individual address code information for function options, 4 is a display unit control unit,
Reference numeral 5 is a display means, 6 is a confirmed code processing control section for processing the change parameter accepted by the code information identification control section 2,
Reference numerals 7 denote fixed code storage units, respectively.

As shown in FIG. 2, the code input means 1 is
Setting change key 1a, code selection key 1b, enter key 1c
It has three key switches. In the code information storage unit 3, all selectable setting items are arranged according to the address code structure shown in FIG. Further, the defined code storage unit 7 stores the data currently defined in the setting items corresponding to all the address codes.

Continuing to refer to FIG. 3, when the setting items consist of a maximum of 4 layers and the number of items in the lower layer relative to 1 item in each layer is within 8 items, the items in one layer are 3 bits. Can be expressed. Further, since it has a hierarchical structure of four layers, as shown in the address code structure of FIG. 4, all selectable items can be expressed by 12 bits. Since the data code is represented by 8 bits, 256 kinds of parameters can be arranged for one setting item. Numerical values from 0 to 255 can be set for the setting items requiring integer data.

Next, the operation of the function setting device according to the present invention will be described with reference to the flowchart of FIG. 6 together with the LED display of FIG.

When the setting change key 1a is pressed by the code input means 1, the address code input mode is first entered. The determination of the address code input mode can be confirmed by displaying "A" on the leftmost end of the 7-segment LED display 10 made up of four, as shown in FIG. The cursor is moved to the second LED display from the left. The address code is input using the following three LED displays, but the input code is Hex code 0h-
Select Fh. In the example shown in FIG. 5, the address code is 02Ch. This is expressed in binary number as "000
0 0010 1100 ", and the setting items corresponding to the items of the first layer 0 item-the second layer 0 item-the third layer 5 item-the fourth layer 4 item are selected from the address code structure shown in FIG. The procedure of inputting the 3-digit Hex data will be described by returning to the flowchart of FIG. 6 again.

First, "0" is displayed on the second LED display from the left. When inputting an alphanumeric character other than "0", the code selection key 1b is repeatedly pressed until the desired alphanumeric character is displayed. Now advance the cursor to the next third LED indicator to enter a "0". To move the cursor, press the enter key 1c once. However, the pressing time is, for example, less than 3 seconds. Similarly, by pressing the code selection key 1b, the codes "2" and "C" are input. The procedure for completing the address code input is determined by pressing the enter key 1c for 3 seconds or more.

At this time, the code information identification control unit 2 confirms whether or not the input address code exists in the code information storage unit 3. Addresses of all four layers (ie 84 =
Since the setting item is not placed in (4096 items), it is necessary to return an error when an invalid address code is input. 4 LEDs at the time of error detection
"AErr" on the display (indicates an address input error)
After displaying for a few seconds, the cursor returns to the second LED display again and waits for the address code input.

When the address code is correctly input, the data code input mode is automatically selected next.
The data code input mode is determined by displaying "d" on the leftmost LED display, as in the address code input mode. Since the data code is represented by 8 bits, only two LED indicators 10 are used.
In the example of FIG. 5, 1bh is designated by the Hex code, which means that the 23rd data of 256 types of parameters is selected. It also means that 22 is selected for the setting item for which numerical input is required.

In the data code input as well as in the address code input, it is necessary to detect the illegal data input, and when it is confirmed that there is no corresponding data in the code information storage section 3, the four LED displays indicate ". After dErr "(indicating a data input error) is displayed for a few seconds, the data code input waits again.

When the confirmation key 1c is pressed for 3 seconds or more at the time when the input of the correct data code is completed, the input code is passed to the confirmation code processing control section 6 and the processing procedure for changing the current parameter setting is performed. . The changed parameter is stored in the confirmation code storage unit 7 and held until the parameter is changed again. If the setting change key 1a is pressed when the data code input is completed, the parameter is not changed and the mode exits from the setting mode.

Next, a specific example of the present invention will be described with reference to FIGS.

7 and 8 are views for explaining a specific example of the present invention.

As an example of changing the function setting in the function setting tree having a hierarchical structure as shown in FIG.
The means for changing the baud rate of 422 from 9600 baud to 4800 baud will be described with reference to FIG.

[0028]

As described above, according to the present invention,
Since it is possible to specify a setting item having a hierarchical structure of n layers by inputting a specific address code, it is not necessary to select an item by a complicated key operation.

According to the present invention, the operator panel can be designed at low cost by using a small number of switches and inexpensive display means such as LEDs.
