The electronic device main body is provided with a battery lock mechanism for fixing the battery device to the electronic device main body.

  However, if the battery lock mechanism is provided for the electronic device main body, the electronic device main body becomes heavier and larger than the battery lock mechanism. In addition, since the conventional battery lock mechanism has been operated as a separate and independent operation for locking and unlocking the battery device and for attaching and removing the battery device, the battery device must be attached / removed. Both hands had to be used, and the operation was annoying. In recent years, battery devices in which a battery lock mechanism is provided on the battery device side and battery devices that can be attached to and detached from the electronic device main body by one-hand operation have been developed in part.

  However, the conventional battery device with the battery lock mechanism on the battery device side is attached to the electronic device main body with the hand of the case directly attached to the electronic device main body or removed from the electronic device main body. At times, it was difficult to grasp the battery body. Further, the conventional battery device that can be attached to and detached from the electronic device main body by one-hand operation is intended for a front insertion type battery device that is inserted into the electronic device main body from the front side of the electronic device main body. Therefore, it has been difficult to apply the configuration of the conventional battery device as it is to a battery device of a face-to-face installation having a different structure.
