Abstract: When an electronic device (e.g., a notebook personal computer) (5) is mounted on an accessory (1), functions of the electronic device (5) are added. To detach the electronic device 85) from the accessory (1), operation levers (37) provided at the rear portions of both sides of the accessory (1) are operated. Since any force necessary to detach the electronic device (5) is not applied until the operation levers (37) are opened to a predetermined angle, the operability of the operation levers (37) does not deteriorate even if the operation levers (37) are so designed as not to project from the accessory (1) in view of the appearance of the accessory (1). To prevent the electronic device from being stolen, a control plate provided in the accessory (1) is set in a predetermined position, and a key (10) is inserted into a lock part (9) fitted to the accessory (1) and rotated so as not to allow the operation levers (37) to be opened.

Abstract: The function of an electronic device (e.g., a portable personal computer) (5) is extended when the electronic device is mounted on an accessory (1). An operation lever (37) attached to the accessory (1) is operated to separate the electronic device (5) from the accessory (1). Operation parts (30, 31) are operated to take out mechanical equipment (8, 15) housed in the accessory (1). There is a setting which enables both the operation lever (37) and the operation parts (30, 31) to be operated, a setting which enables the operation lever (37) to be operated and unables the operation parts (30, 31) to be operated, and a setting which unables both the operation lever (37) and the operation parts (30, 31) to be operated. The user can select a desired setting by position operation of a lock object selecting part (46). The position operation of the lock object selecting part (46) is inhibited by inserting a key (10) into a locking part (9) attached to the accessory (1) and by turning the key (10).
