The above may be provided separately. In the present embodiment, the plate tension bolt 36 is illustrated as a pressing member for pressing the free end of the vise table 25, but it may be pressed by a cam or the like, for example. Further, in the present embodiment, an example in which the present invention is applied to a device for manually supplying the plate 40 to the plate vise device is shown. However, a semi-automatic device for automatically supplying only the plate, a plate supply, The same can be applied to a fully automatic device that automatically removes,
Similar effects can be obtained.

また、準備時間が短縮され機械の稼働率が向上する。According As is apparent to the present invention the above description, according to the invention], in plate clamping device of a printing press, to press the plate gripper side free end notch is supported on the side members of the bottom clamping rail of the barrel by providing the forward and backward adjustable pressing member for oscillating the gripper board together with the bottom clamping rail to the plate lined direction, the plate printing registration in elongation, etc. of the plate baked and printing paper After wearing plate Since the adjustment to be performed when it is shifted in the vertical direction can be performed by a simple operation of pressing the free end of the vise table with the pressing member,
Operation becomes easy, workability is improved, and labor is reduced.
In addition, the preparation time is shortened and the operation rate of the machine is improved.
