Electronic equipment attachable to and removable from a main frame apparatus includes a container and a connector. Guides are formed on both sides of the connector, and aperture portions are provided in these guides such that parts of shutter lock portions are exposed. The lock portions can move between a lock position and a lock releasing position. In the lock position a shutter protects a connection portion of the connector, and in a lock releasing position, the shutter is maintained in a movable state.
