To provide a conveyance device capable of setting a tension condition of a film to a desired state at the time when conveyance of the film is stopped or started in intermittent conveyance of the film.SOLUTION: A conveyance device 10 includes a control device 19. The control device 19 executes intermittent conveyance process S11, unwinding separation process S12, and an unwinding proximity process. The intermittent conveyance process S11 is a process for intermittently conveying a film F1. The unwinding separation process S12 is a process for separating a dancer roll 13 from each of support rolls 11 and 12 so that the amount of conveyance of the film F1 is such that a tension of the film F1 between an unwinding roll FR and each of the conveyance rolls 14 and 15 becomes a desired state. The unwinding proximity process is a process of bringing the dancer roll 13 closer to each of the support rolls 11 and 12 so that the amount of conveyance of the film F1 is such that the tension of the film F1 between the unwinding roll FR and each of the conveyance rolls 14 and 15 becomes the desired state.SELECTED DRAWING: Figure 2 【課題】フィルムの間欠搬送においてフィルムの搬送が停止又は開始された時点でフィルムの張り具合を所望の状態にできる搬送装置を提供すること。【解決手段】搬送装置１０は、制御装置１９を備えている。制御装置１９は、間欠搬送処理Ｓ１１と、巻出離間処理Ｓ１２と、巻出近接処理とを実行する。間欠搬送処理Ｓ１１は、フィルムＦ１を間欠搬送する処理である。巻出離間処理Ｓ１２は、巻出ロールＦＲと各搬送ロール１４，１５との間のフィルムＦ１の張り具合を所望の状態とするフィルムＦ１の搬送量となるようにダンサロール１３を各支持ロール１１，１２から離す処理である。巻出近接処理は、巻出ロールＦＲと各搬送ロール１４，１５との間のフィルムＦ１の張り具合を所望の状態とするフィルムＦ１の搬送量となるようにダンサロール１３を各支持ロール１１，１２に近づける処理である。【選択図】図２
