A die cushion apparatus of a press machine comprising an information acquiring device (23L, 23R) which acquires information regarding inclination of a cushion pad in a duration of die cushion force control, characterized in that in operation the cushion pad is held on standby in parallel with lower faces of dies mounted to a slide of the press machine by carrying out an adjustment, based on the information acquired from the information acquiring device, the die cushion apparatus further comprising: multiple cushion pad raising and lowering devices (4L, 4R) which in operation raise and lower the cushion pad by separately-controllable multiple driving shafts (4La, 4Ra); a die cushion position instructing unit which in operation respectively outputs multiple position instruction values each of which instructs a position in a raising and lowering direction of the cushion pad corresponding to a position of each driving shaft (4La, 4Ra) of the multiple cushion pad raising and lowering devices (4L, 4R), the die cushion position instructing unit including multiple standby position instruction values for at least holding the cushion pad at a standby position, and outputting the multiple standby position instruction values after knocking out a product; multiple die cushion position detecting devices (23L, 23R) which in opeartion detect the position in the raising and lowering direction of the cushion pad corresponding to the position for each driving shaft (4La, 4Ra) of the multiple cushion pad raising and lowering devices (4L, 4R), and separately output position detected values indicating the detected positions; and a controlling device which in operation separately controls the multiple cushion pad raising and lowering devices (4L, 4R) based on the multiple position instruction values outputted from the die cushion position instructing unit, and on the multiple position detected values outputted from the multiple die cushion position detecting devices (23L, 23R), and moves the cushion pad to the standby position based on the multiple standby position instruction values outputted from the die cushion position instructing unit after knocking out the product, wherein the multiple standby position instruction values are adjusted based on the information acquired from the information acquiring device to allow the cushion pad to be held on standby in parallel with the lower faces of dies mounted to the slide of the press machine. multiple cushion pad raising and lowering devices (4L, 4R) which in operation raise and lower the cushion pad by separately-controllable multiple driving shafts (4La, 4Ra); a die cushion position instructing unit which in operation respectively outputs multiple position instruction values each of which instructs a position in a raising and lowering direction of the cushion pad corresponding to a position of each driving shaft (4La, 4Ra) of the multiple cushion pad raising and lowering devices (4L, 4R), the die cushion position instructing unit including multiple standby position instruction values for at least holding the cushion pad at a standby position, and outputting the multiple standby position instruction values after knocking out a product; multiple die cushion position detecting devices (23L, 23R) which in opeartion detect the position in the raising and lowering direction of the cushion pad corresponding to the position for each driving shaft (4La, 4Ra) of the multiple cushion pad raising and lowering devices (4L, 4R), and separately output position detected values indicating the detected positions; and a controlling device which in operation separately controls the multiple cushion pad raising and lowering devices (4L, 4R) based on the multiple position instruction values outputted from the die cushion position instructing unit, and on the multiple position detected values outputted from the multiple die cushion position detecting devices (23L, 23R), and moves the cushion pad to the standby position based on the multiple standby position instruction values outputted from the die cushion position instructing unit after knocking out the product, wherein the multiple standby position instruction values are adjusted based on the information acquired from the information acquiring device to allow the cushion pad to be held on standby in parallel with the lower faces of dies mounted to the slide of the press machine.
