PURPOSE:To prevent an error insertion to an electron device during the operation resulting from the failure of cable mounting, by providing a device to make it impossible to install unless an interface circuit inserted to the electron device is locked, to an electron circuit package. CONSTITUTION:An electron circuit package including a printed wiring plate 1 is inserted to an electron device 9 in operation. A lever 3 and a stopper 6 rotatable around shafts 2 and 5 respectively are furnished on the printed wiring plate 1, and both members are enforced in the reverse directions each other by a spring 4. When a cable connector 10 is not installed to a connector 7 fixed to the printed wiring plate 1, the lever 3 and the stopper 6 are geared each other to project the end 6a of the stopper 6 to deny the insertion to the electron device 9. When the cable connector 10 is installed to the connector 7, the end 6a is pulled to the inner side, and at the same time, an interface circuit is locked. |
