1. An electronic component mounting device which performs a predetermined operation for mounting each of electronic components on a board on which the electronic components are to be mounted, comprising:
an operating performing mechanism which comprises an operating head that performs the operation and which performs the operation by making the operating head move up and down to operation positions where the operation is performed on the board;
a height measuring device which measures a height position on the top surface of the board at any measurement point;
an operation information storage part which, for each of the operation positions, stores operation data which make operation position information indicating position coordinates in the board of the operation positions to correspond to height precision division information that divide height precision required for up and down movements of the operating head in the operation into a first division which indicates a normal height precision and a second division which indicates that a high height precision is required based on the type of electronic components beforehand; and
an operation control part which makes the operating head to perform the operation by reading out the operation data from the operation information storage parts and controlling the operation performing mechanism based on the operation data;
wherein, when the electronic component which is an operation object belongs to the first division, the operation control part controls the operation performing mechanism to make the operating head to move up and down based on an approximate operation position height derived from an approximate curved surface of the top surface of the board which is calculated by using a height measurement result obtained on a plurality of height measuring points on the top surface of the board, and
when the electronic component which is an operation object belongs to the second division, the operation control part controls the operation performing mechanism to make the operating head to move up and down based on an individual operation position height obtained when the height measuring device individually measures the board height at the operation position.

The electronic component mounting device according to claim 1 , wherein the electronic component mounting device is one device which an electronic component mounting line which is formed by coupling a plurality of electronic component mounting devices, comprises, and the operation control part derives the approximate operation position height by using an approximate curved surface of the top surface of the board which is calculated by a height measuring device which is provided in the electronic component mounting line.
3. The electronic component mounting device according to claim 1 , wherein the height measuring device in the electronic component mounting device performs a height measurement to calculate an approximate curved surface of the top surface of the board, and the operation control part derives the approximate operation position height by using the approximate curved surface of the top surface of the board which is calculated by the electronic component mounting device.
4. An operation performing method for mounting electronic components which performs a predetermined operation for mounting each of electronic components on a board on which the electronic components are to be mounted by making an operating head which is included in an operation performing mechanism to move up and down to operation positions where the operation is performed on the board, comprising:
an operation information storing procedure of storing, for each of the operation positions, operation data which make operation position information indicating position coordinates in the board of the operation positions to correspond to height precision division information that divide height precision required for up and down movements of the operating head in the operation into a first division which indicates a normal height precision and a second division which indicates that a high height precision is required based on the type of electronic components; and
an operation performing procedure of making the operating head to perform the operation by reading out the stored operation data and controlling the operation performing mechanism based on the operation data;
wherein in the operation performing procedures, when the electronic component which is an operation object belongs to the first division, the operating head is made to move up and down based on an approximate operation position height derived from an approximate curved surface of the top surface of the board which is calculated by using the height measurement result obtained on a plurality of height measuring points on the top surface of the board, and
when the electronic component which is an operation object belongs to the second division, the operating head is made to move up and down based on an individual operation position height obtained by individually measuring the board height at the operation position.
