In order to construct this personal computer system, it is necessary to connect the bus connecting connectors provided in the personal computer and the station, respectively. Also, although not publicly known, from the same purpose,
A personal computer system capable of connecting a portable personal computer to a stationary personal computer is also being considered. Also in constructing this personal computer system, it is necessary to connect the bus connection connectors provided on both personal computers.

[0003]

By the way, when connecting the connectors for bus connection, it is necessary to connect both devices after turning off the power switch of the devices. This is because if either one of them is powered on, chattering may occur and data may be destroyed. Therefore, conventionally, when connecting the bus connecting connectors, both electronic devices are connected after the user turns off the power supply of the devices. However, it is troublesome to turn off the power of the electronic device prior to each time the system is constructed. Also, sometimes, I accidentally connected both devices without forgetting to turn off the power. In particular, in an electronic device having a resume function, this error may be unavoidably generated.

The present invention has been made in order to solve such a problem, and provides a connection structure for electronic equipment which is easy to connect and can surely prevent data destruction due to chattering. It is intended to be provided.

SUMMARY OF THE INVENTION The present invention is an electronic device in which both electronic devices are connected by connecting a bus connecting connector of one electronic device and a bus connecting connector of another electronic device. In one of the electronic structures, the detection rod that can be retracted from the main body of the electronic device, the biasing means that biases the detection rod in the protruding direction, and the detection rod that is retracted. And a switch for cutting off the power supply of the electronic device when the detection unit detects that the detection rod is immersed, and the other electronic device is provided with a tip of the detection rod. Detecting unit, a switch that shuts off the power supply of the electronic device when the tip of the detecting rod is detected by the detecting unit, and the detecting rod that opposes as the electronic devices approach each other. It provided a pressing means for immersion in a body of the electronic device, wherein before connecting said bus connecting the connectors is what is adapted to cut off the power supply of the two electronic devices.

[0006]

According to the above means, when one electronic device is brought close to another electronic device in order to connect the bus connecting connectors, the tip of the detection rod of the one electronic device detects the other electronic device. Detected by the unit and the power supply to the other electronic device is first shut down. Further, when the electronic devices are brought closer to each other, the detection rod is immersed in the electronic device main body by the pressing means, and the power of the electronic device is shut off by the immersion. Thereafter, the bus connecting connectors are connected to each other. Therefore, since the connection is automatically made in the state where the power is cut off, chattering can be easily and surely prevented.
