Ｌ（図３参照）の紐状体ＢＬ１が連結される。Reference numeral 1 is a printing plate mounting aid. The plate mounting aid 1 is used for mounting the plate IP when mounting the plate IP on the plate cylinder PC.
It is used to bend the other side of the plate, that is, a part which is usually called the gripper side, toward the plate tensioning means 50 provided in the groove 51 of the plate cylinder PC. A plate pressing unit 11 that comes into contact with the plate to bend it and a handling unit 12 that the operator holds for handling are provided.
Further, in the illustrated embodiment, in order to prevent the plate IP from being excessively pressed to cause unnecessary deformation on the gripper side, it is necessary to properly maintain the posture of the plate mounting aid 1 during use. A stopper 13 is provided, and a constant output spring mechanism B is provided to help reduce the weight of the plate mounting aid 1 and prevent it from being lost.
The L-shaped string BL1 (see FIG. 3) is connected.

ものである。The printing plate pressing portion 11 is made of a synthetic resin having a low hardness and a light weight, for example, polypropylene resin, so as not to damage the surface of the printing plate IP and in consideration of weight reduction of the printing plate mounting aid 1. Further, the plate retainer 11 is provided with a plate I.
Along the width direction of P, it is configured to be able to be pressed continuously or at a plurality of points in a discontinuous manner.
In the plate retainer 11, the distance L between both ends of the press position (see FIG. 2) is at least about half the width of the plate IP,
The stopper 13 is provided in an appropriate form while preventing damage to the printing plate IP by using a soft material at a portion contacting the printing plate IP. The handling unit 12 is the plate pressing unit 1.
A part of 1 may be processed and provided. Incidentally, HO is a storage means for storing the plate mounting aid 1 when not in use.
