Printing apparatus, printing material cartridge, printing material container adapter, cartridge set, and adapter set

A cartridge set comprising:

• N (N is an integer equal to or greater than 2) printing material cartridges which can be independently mounted in a holder of a printing apparatus which has a mounting detection circuit for the printing material cartridges,
• wherein each of the N printing material cartridges includes a storage device for storing information regarding a printing material which is contained, an electric device for mounting detection which is connected in parallel with the mounting detection circuit, a terminal for the storage device, and a terminal for the electric device, and
• the electric devices of the N printing material cartridges are configured so that a detection voltage detected by the mounting detection circuit becomes equal to or greater than a threshold voltage set in advance when the N printing material cartridges are all mounted in the holder.

An adapter set comprising:

• N (N is an integer equal to or greater than 2) printing material container adapters which can be independently mounted in a holder of a printing apparatus which has a mounting detection circuit for the printing material container adapters,
• wherein each of the N printing material container adapters includes a storage device for storing information regarding a printing material which is contained in a printing material container, an electric device for mounting detection which is connected in parallel with the mounting detection circuit, a terminal for the storage device, and a terminal for the electric device, and
• the electric devices of the N printing material container adapters are configured so that a detection voltage detected by the mounting detection circuit becomes equal to or greater than a threshold voltage set in advance when the N printing material container adapters are all mounted in the holder.
