To provide a device for producing a laver sheet, capable of easily its increasing its production capacity, and further improving the drying performance of the laver.

This device for producing the laver sheet has a driving mechanism 40 which is characterized by having a driving mechanism 41 for a machine stand for transmitting a driving force outputted from a driving motor 35 to a pawl chain conveyer 7 by converting it to a one directional intermittent rotational movement by a Geneva mechanism 43, and a driving mechanism 42 for a drier for outputting by converting the driving force outputted from the driving motor 35 to a prescribed movement through a cam mechanism 60 and converting the output to a one directional intermittent rotational movement by a pawl 61 and rachet 62 for transmitting it to a blade chain conveyer 24.
