PURPOSE:To provide an interlock mechanism in which the connector of control line can not be removed when a machine is in the operating position and the machine can be pushed into the operating position only when the connector is connected. CONSTITUTION:When a machine body 1 is at an operating position, an interlock pin 15 strikes against an interlock plate 30 to block lowering of a slide plate 14 which thereby engages with a protrusion 7 of a connector 3 thus preventing removal of the connector 3. When the machine body 1 is a disconnecting position, the pin 15 does not strike against the plate 30 and thereby the slide plate 14 descends to release an engaging piece 7. When the connector 3 is drawn out along with a protrusion 8, a rod 13 advances and a pin 24 descends to interfere with the plate 30 thus blocking push-in of the machine body 1. When the connector 3 is connected, the pin 15 and the slide plate 14 are lowered to clear the front side of the engaging piece 7. Upon insertion of the connector 3, the slide plate 14 returns to engage with the piece 7 thus preventing removal of the connector 7. At the time of insertion, the protrusion 8 pushes a rod 23 to place the pin 24 on the plate 30 and then the machine body 1 is pushed into an operating position. |
