1. A slot die coater adjusting device, comprising:
pressing block assemblies respectively provided to both longitudinal sides of a slot die coater and fixed to an upper die of the slot die coater;
a linear motion (LM) guide disposed at a lower portion of the pressing block assembly and connected to the pressing block assembly to guide a movement of the pressing block assembly;
a servo motor configured to give a power for moving the LM guide; and
a reducer connected between the servo motor and the LM guide,
wherein the slot die coater adjusting device is configured to adjust the slot die coater including a lower die having a lower discharge hole for discharging a first active material slurry and the upper die having an upper discharge hole for discharging a second active material slurry, to adjust a distance between the lower discharge hole and the upper discharge hole by allowing the upper die to move,
wherein the pressing block assembly includes:
a cam follower fixed to the upper die; and
a pressing block fixed on the LM guide and having an insert hole into which the cam follower is inserted.
