This abstract first appeared for US patent application 18348542 titled 'ELECTRONIC APPARATUS AND ITS CONTROL METHOD, AND ACCESSORY AND ITS CONTROL METHOD

Simplified Explanation

The patent application describes an accessory that can communicate with an electronic device.

  • The accessory has multiple communication contacts, including a first contact.
  • A control unit in the accessory notifies the electronic device of a communication request by changing the signal level of the first contact.
  • The control unit also transmits information about the communication factor when requested by the electronic device.
  • If the control unit notifies the electronic device of the communication request when the power supply starts, it can perform predetermined communication without receiving or transmitting the information about the communication factor.


Original Abstract Submitted

An accessory includes a plurality of communication contacts that includes a first contact, and a control unit that notifies an electronic apparatus of a communication request by changing a signal level of the first contact from a first signal level to a second signal level different from the first signal level, and transmits information indicating a communication factor in response to a reception of a request for the information indicating the communication factor in response to a notification of the communication request. In a case where the control unit notifies the electronic apparatus of the communication request via the first contact in response to a start of a power supply, the control unit performs predetermined communication without receiving the request for the information indicating the communication factor or transmitting the information indicating the communication factor.
