2. Description of the Related Art Recently, electronic devices have been unitized, and by connecting each unit, the function can be improved. In addition, integrated circuit memory has been developed and is used for small electronic devices such as electronic organizers and electronic wrist watches.
It has been proposed that it can be detachably attached to improve the function. For example, the integrated circuit memory can be attached to an electronic wrist watch, an electronic notebook, or the like to effectively use the data stored in the integrated circuit memory. Such a conventional unit or an electronic device such as an integrated circuit memory has a connection between the units or an electronic device in order to ensure the connection between the connection terminal of the electronic device and the connection terminal of the counterpart unit or the electronic device. The mounting angle is set in advance, and if the mounting angle is not set, the connection between the connection terminals cannot be performed accurately. Therefore, conventionally, in order to set the mounting angle of the electronic device to the connection partner, the shape of the electronic device is shaped to restrict the mounting angle, or a fitting member for restricting the mounting angle, for example, a protrusion. Recesses and the like are formed in the electronic device and the counterpart unit or electronic device.

However, in such a conventional electronic device, the mounting angle between the electronic device and the counterpart device is preset and the mounting angle of the electronic device is restricted. The shape of the electronic device and the fitting member for restricting the mounting angle are formed on the electronic device. Therefore, you can adjust the mounting angle to mount the electronic device or adjust the mounting angle so that the fitting member fits. However, there is a problem in that the mounting operation of the electronic device is troublesome and the usability is poor. In particular, in an electronic device in which the connection terminals are fitted and mounted, it is difficult to match the connection terminals,
There is a problem that the mounting operation of the electronic device may be difficult. Further, in the electronic device forming the fitting member, there is a problem that the appearance of the electronic device is impaired by the fitting member. Therefore, the present invention automatically determines the mounting angle of the electronic device to the connection board, and automatically selects an appropriate connection terminal for the connection terminal of the connection board, thereby simplifying the mounting operation of the electronic device. The purpose of the invention is to improve the usability of the electronic device and to improve the appearance of the electronic device by eliminating the fitting member.
