Abstract:
1. A method for determining a size of an electronic apparatus used for an external apparatus, the electronic apparatus comprising a connector for electrically connecting to the external apparatus, and a leaning supporting plate for supporting a back surface of the external apparatus when a bottom part of the external apparatus is mounted on the electronic apparatus via the connector, the method comprising: defining the external apparatus to comprise a first plane parallel to the back surface of the external apparatus and on which a central plane in a longitudinal direction of the connector is located, the first plane being a rectangle shape which has an up edge, a down edge, and two side edges; defining the electronic apparatus to comprise a second plane that includes the top surface of the electronic apparatus, an angle between the first plane and the second plane being an acute angle θ, the second plane being a rectangle shape which has a front edge, a back edge, and two side edges, the front edge of the second plane overlapping with the down edge of the first plane; determining a length of the electronic apparatus by balancing moment of forces on a first fulcrum, based at least in part upon a first acting force, a gravity of the external apparatus, and a length of the external apparatus, such that the external apparatus does not rotate with respect to the electronic apparatus, the first fulcrum being located on an edge of a side surface of the electronic apparatus which contacts the external apparatus at a side on which the first acting force is located, and wherein the determination comprises: using an end point of the up edge of the first plane as a first force bearing point, applying the first actin force F
