ABSTRACT:
A notch is formed in a lateral edge of a contact printing plate. An arresting lever is pivotally mounted in a plate guide path for guiding the contract printing plate into a printing position. The arresting lever is urged to protrude into the plate guide path, such that when the contact printing plate is inserted in a normal state into the plate guide member, the arresting lever is not engaged in the notch of the contact printing plate, but if the contact printing plate is inserted in the reversed state, the arresting lever engages in the notch and thus prevents the contact printing plate from moving further into the plate guide member. The contact printing plate has a pushing surface for pushing the arresting lever aside from the plate guide path.
