To the communication of information.
In order to transmit information (e.g., tool number) electrically set in the tool holder to the housing, for example, a transmitting coil or a light transmitting element is attached to a side surface of the tool holder, and a signal is received correspondingly. For receiving coil,
Alternatively, a light-receiving element may be provided on the housing side to perform signal transmission electromagnetically or using light, and this is extremely diversified and a known method can be applied. In the signal transmitted from the tool holder, for example, the frequency of the transmitted signal represents the number of the tool, and setting of this frequency (that is, setting of the number) can be easily realized by changing the electrical constant of the oscillation circuit, for example. What can be done is very well known. Thus, the problem of communication between the tool holder and the housing results in how to supply power to the tool holder as a basic condition for communication.
