In this state, when a start operation is performed on the root canal length measuring instrument 10 side, the operation is also started on the functional module 20 side, and a module code transmission request is made from the root canal length measuring instrument 10, and the function is received. In the module 20, when the module code is transmitted by the recognition giving means 11, the root canal length measuring instrument 10 receives this module code signal and recognizes which functional module 20 is connected by the module recognition means 6 (S1, S1). S11), a function program reception standby state is entered.

Subsequently, the functional module 20 transmits the stored function program (control software) to the root canal length measuring instrument 10 (S12), and the root canal length measuring apparatus 10 receives this function program. (S2) For example, as shown in (b), the data is stored after address 4000H of the memory map.

When this reception is completed, the root canal length measuring instrument 10 moves the process to the address (4000H) where the saved function program is located (S3), and the medical function of the function module 20 to which the display unit 1, the operation unit 2, etc. are connected. The function program of the functional module 20 is executed (S4) while exchanging data with the functional module 20 as necessary (S13).

In this way, between the root canal length measuring unit 10 and the function module 20, communication is performed, it is performed transmission and reception of various data, the root canal length measuring unit 10 side, connected functional module 20 Medical functions can be used. Further, in this case, even if a version upgrade of the control software in the medical facility to replace the function module side of the control software memory means (ROM), or to replace the function module to those of the new features With that, you can respond.

Here, the “module code” is a concept that widely includes various signals and codes for recognizing a functional module. Further, for example, a code such as “100010” can be used for a function module having a root canal enlargement function, and “010101” can be used for a function module having a photopolymerization function.

The communication information communicated between the root canal length measuring instrument 10 and the functional module 20 includes display, operation input, medical data information relating to the medical function of the functional module 20, and instruments 8 and 16 to be connected. The device information and the control information may be at least one of these.
