To provide a connecting mechanism between a die and a cutter unit which can connect and disconnect the cutter unit to the die even when a center axis of the die and the cutter unit is deviated in a present invention.SOLUTION: A connecting mechanism between a die 8 and a cutter unit 9 according to a present invention has the die 8, a die holder 32 in which the die 8 is fixed and a notch 33 having an opening end 331 and a closed end 332 having a narrow width is formed, and the cutter unit 9 having a lock bar 21 consisting of a first rod part 211 extending toward the die 8, a protrusion 27 attached to a tip end of the first rod part 211, and a second rod part 212 extending in a direction inclined with respect to the first rod part 211, and drive means 22 for driving the lock bar 21. With the protrusion 27 of the lock bar 21 in contact with a rear surface of the die holder 32, the first rod part 211 contacts an inner edge of the closed end 332.SELECTED DRAWING: Figure 5 【課題】本発明は、ダイスとカッタユニットの中心軸のずれが生じている場合でも、ダイスへのカッタユニットの連結および切り離しが可能なダイスとカッタユニットとの連結機構を提供する。【解決手段】本発明に係るダイス８とカッタユニット９との連結機構は、ダイス８と、ダイス８を固定し、開口端部３３１と幅が狭い閉じた端部３３２を有する切欠部３３が形成されたダイホルダ３２と、ダイス８に向かって延びる第１のロッド部２１１と第１のロッド部２１１の先端に取付けられた突起部２７と第１のロッド部２１１に対して傾斜する方向に延びる第２のロッド部２１２とからなるロックバー２１と、ロックバー２１を駆動する駆動手段２２と、を備えたカッタユニット９と、を備え、ロックバー２１の突起部２７がダイホルダ３２の背面に当接する状態で第１のロッド部２１１が閉じた端部３３２の内側縁部に当接する。【選択図】図５
