displaying the icon of the function that is described as necessary and the icon of the function that is described as unnecessary such that they are distinguished by at least one of at least one of a size, a shape, a color, and a behavior so as to demonstrate the necessity information of the function that is described as necessary and the necessity information of the function that is described as unnecessary, wherein

the data associated with the operation of the electronic component mounting machines includes part data which instructs an operation condition for each type of electronic component, and

the one or more processors is configured to cause the display to display a figure that illustrates a shape of the electronic component and the operation condition described by the part data at the same time as when displaying the plurality of icons.

2. The device according to claim 1 , wherein the one or more processors is configured to cause the display to display a plurality of necessary icons corresponding to functions of the plurality of functions which are described as necessary by the necessity information at the same time.

3. The device according to claim 1 , wherein the one or more processors is configured to cause the display to display a plurality of necessary icons corresponding to all functions of the plurality of functions which are described as necessary by the necessity information at the same time.

4. The device according to claim 1 , wherein the one or more processors is configured to cause the display to display a plurality of necessary icons corresponding to functions of the plurality of functions which are described as necessary by the necessity information at respective predetermined positions regardless of necessity of other functions of the plurality of functions.

5. The device according to claim 1 , wherein

when an operator selects one of the icons, the one or more processors is configured to cause the display to display a setting screen, and

a setting screen includes parameters related to the function of the plurality of functions that corresponds to the one of the icons.

6. The device according to claim 1 , wherein the one or more processors is configured to:

extract the necessity information from two or more pieces of instruction data, and

cause the display to display the necessity information which is extracted from one piece of the two or more pieces of instruction data and the necessity information which is extracted from another piece of the two or more pieces of instruction data at the same time.

7. The device according to claim 1 , wherein the one or more processors is configured to cause the display to simultaneously display the plurality of icons.

8. The device according to claim 1 , wherein the one or more processors is configured to:

cause the display to display the icon of the function which is described as necessary as selectable, and

cause the display to display the icon of the function which is described as unnecessary as selectable.

9. The device according to claim 1 , wherein

when an operator selects the icon of the function which is described as necessary, the one or more processor is configured to cause the display to display a setting screen for the function which is described as necessary,

the setting screen includes parameters related to the function which is described as necessary,

the setting screen includes the icon of the function which is described as necessary,

the setting screen includes the icon of the function which is described as unnecessary in a manner that demonstrates that the function which is described as unnecessary is unnecessary without having to scroll or change the display.

10. The device according to claim 1 , wherein the one or more processors is configured to cause the display to display a plurality of necessary icons corresponding to functions of the plurality of functions which are described as necessary by the necessity information.

11. The device according to claim 10 , wherein the one or more processors is configured to cause the display to display a plurality of unnecessary icons corresponding to functions of the plurality of functions which are described as unnecessary by the necessity information.

12. A system comprising:

the display device according to claim 1 ; and

the electronic component mounting machines, wherein

the workpieces are circuit boards, and

the electronic component mounting machines mount electronic components on the circuit boards in accordance with the data.

13. The system according to claim 12 , wherein the display device is a part of the one of the electronic component mounting machines.

14. The device according to claim 1 , wherein the one or more processors is configured to:

cause the display to display a setting screen;

cause the display to display an indicator of the necessity of use of one of the plurality of functions on the setting screen based on the necessity information;

cause the display to display the indicator of the necessity of use of the one of the plurality of functions as necessary based on the necessity information;

accept setting of the necessity information of the one of the plurality of functions as unnecessary via the setting screen;

cause the display to display the indicator of the necessity of use of the one of the plurality of functions as unnecessary based on the setting of the necessity information.

15. The device according to claim 14 , wherein the one or more processors is configured to cause the display to display the indicator of the necessity of use of the one of the plurality of functions as a label.
