2. Description of the Related Art Flat sheet materials such as photosensitive lithographic printing plates (hereinafter referred to as PS plates) have a plurality of types (plate types such as size and negative / positive), and are randomly selected. Often sent to the process. For this reason, it is necessary to store the PS plates on a plurality of mounting tables (hereinafter referred to as "skids") sorted by type.

The skid has a role as a carrier for transporting the PS plate and can be positioned as it is at a position for taking out and feeding the PS plate one by one to the subsequent step.

Here, in order to prevent damage and plate misalignment of the stacked PS plates during transportation of the skid, a top plate is arranged on the uppermost PS plate and the skids are transported while being fixed by a belt or the like. It is like this. This top plate is removed after the skid is positioned at the post-process feed position of the PS plate.

When all of the stacked PS plates are exhausted, the skid body is sent back to a predetermined place (for example, a PS plate manufacturing factory) by a truck or the like to re-stack the PS plates.
At this time, since the top plate needs to be sent back in pairs with the skid body, a pair of guide rails is provided on the back side of the skid body so that the top plate removed from the top layer of the PS plate can be accommodated in this guide rail. ing. After the housing, the thumbscrew attached to the upper guide rail is tightened, and the tip of the thumbscrew presses the top surface of the top plate to fix it.

[0006]

However, with the means for holding the top plate by the thumbscrew, it takes a lot of time to turn the thumbscrew until it is securely tightened, and if the top plate is released too much, the thumbscrew will bend. However, there is a problem that the guide rail may be lost by dropping from the guide rail.

Further, when the screw is tightened and loosened repeatedly, the screw thread is deformed and the tightening and loosening work cannot be performed, and the structure of the thumbscrew is narrow due to the structure, so that the workability is poor and the tightening work is difficult. In some cases, the top plate may fall off the guide rail during transportation due to lack of space.

In consideration of the above facts, an object of the present invention is to obtain a sheet material mounting table which can securely hold the top plate with one touch after the top plate is housed in the guide rail.

The engagement member is held by screwing the male screw and the female screw in advance.

The invention according to claim 5 is characterized in that the engaging member is a lock pin.

[0014]

According to the first aspect of the present invention, the top plate is removed from the uppermost layer of the sheet material when the placing portion main body is placed at a predetermined position. The top plates that have been removed need to be carried as a pair when the mounting section main body is transported (for example, it is sent back to the factory with a truck to stack the sheet materials again), so it is necessary to carry it on the mounting surface. It is accommodated in a pair of guide rails provided on the side.

That is, the guide rails are substantially U-shaped with their openings opposed to each other, and can be accommodated by inserting the top plate from one longitudinal end of the guide rail.

Here, when the notch formed in the top plate and the through hole formed in the upper guide rail coincide with each other,
