[Problems to be solved by the invention]
In the electronic device and the expansion unit having the conventional guide mechanism described above, the guide mechanism between the electronic device main body and the expansion unit is provided in the vicinity of the connector, and the electronic device main body and the expansion unit are largely misaligned. The guide pin, which is a guide mechanism, may come into contact with the electronic device main body or the expansion unit, and scratches or unnecessary destructive stress may be applied to the appearance of the guide pin, the electronic device main body, or the expansion unit. Furthermore, to guide to the correct position, it is necessary to increase the guide amount. However, since the pin is fixed, if the pin is lengthened, the depth of the guide hole on the other side must be increased. However, portable electronic devices have recently been required to be thin, and it has been difficult to deepen the guide holes. For this reason, the guide amount is small, and another guide mechanism such as using a part of the outer shape of the electronic device is required. In addition, unnecessary electromagnetic waves are emitted from the guide mechanism during docking, causing malfunctions in the main circuit board and the like on which electronic devices and semiconductor components in the expansion unit are mounted.
[0007]
The present invention enables the guide pin to move only when the docking position between the electronic device main body and the expansion unit matches, ensures a sufficient guide amount to the docking position, and the guide mechanism includes the electronic device main body and the expansion unit. An object is to reduce the electromagnetic wave emitted by electrically stable continuity between and.
[0008]
[Means for Solving the Problems]
In order to solve this problem, the present invention relates to an electronic device having a main body that accommodates a main circuit board or the like on which a semiconductor component is mounted, and is detachably and electrically connected to the electronic device. In the expansion unit that expands the function, a guide mechanism that is movably attached in a guide direction is provided in either the electronic device or the expansion unit, and the electronic device and the expansion unit are electrically connected. While guiding the other to the docking position where the connectors are coupled together, either the electronic device or the expansion unit is provided with a concave shape, and the other guide mechanism is provided with a lock mechanism that restricts the movement of the guide mechanism. The locking mechanism is released only when the concave shape matches the position of the guide mechanism, and the electronic device or the expansion unit is released. After contact with the bets, docking position where connectors for electrical connection is coupled, the guide mechanism is that configured movable.
[0009]
As a result, the electronic device main body and the expansion unit correct the position between the connectors without causing unnecessary destructive stress during docking, and a large amount of guide is obtained until the connectors are joined. The frame ground between the main body and the expansion unit is strengthened, and the effect of reducing the radiated electromagnetic wave is obtained.
