Abstract
An accessory capable of promptly notifying an electronic apparatus of its state change. The accessory is detachably connected to an electronic apparatus. A first transmission unit transmits first information among information stored in the accessory to the electronic apparatus in response to periodic first communication from a first communication unit of the electronic apparatus. A second transmission unit responds to inquiry by second communication from a second communication unit of the electronic apparatus. A notification unit notifies the electronic apparatus of state change of the accessory when the electronic apparatus is in a first state or a second state and the state of the accessory is changed. In the first state, the first communication is stopped and the second communication unit is in a standby mode. In the second state, power supply to the first communication unit is stopped and the second communication unit is in the standby mode.
