Electronic equipment and electronic equipment system
First Claim
1. An electronic equipment to/from which an extension device for extending a function can be freely attached and detached, comprising:
- connecting means for mechanically connecting said extension device to a main body of said electronic equipment;
locking means for locking a release of the connecting of said connecting means;
switching means for indicating supply/stop of a power supply to said main body; and
release indicating means for, when a supply of the power supply is indicated by said switching means, indicating a release of the connecting of said extension device, and wherein at the time of indicating a stop of the power supply by said switching means when the release of the connecting of said extension device is indicated by said release indicating means, a locking of said locking means is released.

Abstract
A locking system has a double locking mechanisms such that when a main body of an electronic equipment and an extension device are combined, an operability similar to that in case of using a single equipment is maintained and the combination is not separated at the time of carrying and which enables a more intelligent control by a built-in MPU and in which a high reliability is obtained. In an electronic equipment system in which a main body and an extension device are freely combined, an open-close-lever which is interlocked with movable claws is arranged on the side surface of the extension device, retaining holes to fix the movable claws are formed in the main body, an electronic locking unit comprising a mechanism having a cam portion adapted to lock the opening or closing of the lever and an electronic motor for making the cam operative is installed in the extension device. The movable claws couple and fix the main body and the extension device by closing the open-close-lever. At the time of the power-ON of the main body and extension device, an electronic locking acts, thereby disabling the locking to be released, and at the time of the power-OFF, the locking can be released. A connecting state between the electronic equipment and the extension device is discriminated from two sensors for detecting the opening/closing of the open-close-lever and the latching of the electronic locking.
