The photo-4-electroconductive sheet conveyed by the upstream region facing ■ and ■ is double charged by the corona band 1 of the charging mechanism at the device q→, (7), and the sheet support mechanism between the charging mechanism and the current ms structure is supported. The film is brought into close contact with a roll group i', and after selective exposure with a laser, is sandwiched and transported between two opposing rolls 12'W in the downstream region of the transport mechanism. Opposing roll (■) in the upstream area, opposite roll (■) is the driving roll. This is a non-driven roll with an opposing roll (not shown), which is pressed by a pressing device such as a plunger or a striped coil (not shown) so that its axis is parallel to that of the opposing roll (■), and its outer periphery is in a straight line. It is designed to come into contact with the opposing roll (

In this drive, the downstream opposing roll 20', ■≧)
The speed of the opposing rolls (2) and (2) in the upstream area is driven slightly faster than the speed of (i). This is due to the fact that as the light guide sheet moves forward while being held between the opposing rolls ■, ■ and 129', O, the opposing rolls ■ and ■ are in tension.
This is to prevent the photoconductive sheet from sagging or curling between the two opposing rolls. - When conveying the sheet, there is no inconvenience until the opposing rolls ■ and ■ act on the photoconductive sheet as tension rolls, and at the initial stage when they act as tension rolls, but as the sheet progresses further, the photoconductive sheet becomes Since the moving speed of the photoconductive sheet is faster than the circumferential speed of the opposing roll, the tension is higher than necessary, which tends to cause scratches on the photoconductive sheet, and the motor output is also required to be slightly larger. Such inconveniences may occur. To solve these problems, a unidirectional rotatable latch (2), which rotates only in the sheet conveyance direction, is connected to the opposing roll (2) in the upstream area. That is, the photoconductive sheet is conveyed by opposing rolls 0' and 0 in the downstream area,
When the opposing rolls ■ and (su) in the upstream area function as tension rolls, the opposing rolls in the E area until the input part sprocket no. The opposing rolls ■ and ■, which are the clamping surfaces of the photoconductive sheet, are rotated faster by the rotating clutch ■ than the rotation by human power via the sprocket ■.This is synchronized with the circumferential speed of the opposing rolls d and Q, that is, the advancing speed of the photoconductive sheet. This is because it fulfills the role of a tension roll and allows smooth conveyance without causing any inconvenient knobs.

In addition, as can be understood from FIG.
It consists of one suction support roll and one suction support roll. As mentioned above, the suction support roll 0 is a roll that rotates freely on a bearing such as a bearing.
Air can be sucked in through the opening O drilled around the roll by the action of a pipe (1Φ) attached to the end face of the roll and a suction mechanism (2o) connected to the pipe (1Φ). (See Figure 6).

Since this support roll group has a group of support rolls with a small diameter, there is little impact between the photoconductive sheet and the rolls during conveyance, and moreover, it is in line contact with the photoconductive sheet through a very narrow line. Therefore, the influence of static electricity (frictional resistance) is much smaller than the surface contact of f, L'i of fmet K. The material of the support roll group QS' may be a metal part or an insulating material. In addition, in this embodiment, the flap 11 that can freely rotate is used.
- Each support roll is driven in advance by a synchronous motor or a control motor to further reduce the impact between the photoconductive sheet and the support roll group during conveyance.
It may also be arranged so that it is conveyed.

Furthermore, the photoconductive sheet that has passed through Isohada in Obiichi is first detected by a sensor fixed at a predetermined position (not shown), which starts a suction mechanism such as a fan blower or air pump.
Next, air from the suction roll 0 of the support roll group (!) is taken out through the biply pipe, and the inside of the suction roll ■ of the support roll group is used as a takeda to conduct photoconductivity. The sheet is brought into firm contact with the support roll group ticket.Also, this suction roll is not shown in the figure.
It has a mechanism that rotates at the same speed on the back of the transparent conductive sheet.

In this embodiment, the photoconductive sheet is conveyed in close contact with the support roll group, but if there is no negative effect on the conveyance, it is also possible to use static electricity to convey the photoconductive sheet in close contact with the support roll group. In this case, the mechanism can be greatly simplified because the suction mechanism and suction roll are unnecessary.

[Scope of Claims] A supply mechanism for supplying a photoconductive sheet, an upstream facing roll and a downstream facing roll for sandwiching and conveying the photoconductive sheet supplied from the supplying mechanism between two opposing rolls. a conveying mechanism provided, a charging mechanism that charges the photoconductive sheet conveyed by the upstream opposing roll with an electrostatic charge, and a charging mechanism that holds the photoconductive sheet in a flat state in contact with the back side of the photoconductive sheet sent out from the charging mechanism. a sheet support mechanism held by the sheet support mechanism; an exposure mechanism that image-exposes the photoconductive sheet held by the sheet support mechanism with a laser beam; a development mechanism that develops an electrostatic latent image formed by the laser exposure mechanism with toner;
In a plate-making apparatus that includes at least a fixing and drying mechanism for fixing and drying a developed photoconductive sheet, a sheet support mechanism that supports the photoconductive sheet between the charging mechanism and the developing mechanism is configured to A plurality of support rolls rotating in contact with the back surface of the sheet are arranged such that the top of each is in the same plane as the bottom roll of the upstream area opposing roll and the top of the bottom roll of the downstream area opposing roll, and each What is claimed is: 1. A plate-making apparatus comprising a group of support rolls arranged such that their rotational axes are perpendicular to the conveying direction of the photoconductive sheet. (2) Claim 1, characterized in that the support roll group of the sheet support mechanism that supports the photoconductive sheet is a free roll group that rotates freely at the same speed in contact with the back surface of the photoconductive sheet. The plate-making device described in Section 1. (3) Claims characterized in that the support roll group of the sheet support mechanism that supports the photoconductive sheet is driven by a synchronous motor, a control motor, etc., and rotates at the same speed in contact with the back surface of the photoconductive sheet. The plate-making device according to item 1. (4) A plate making apparatus according to any one of claims 1 to 3, characterized in that a suction support roll and a suction mechanism are provided in a group of support rolls of a sheet support mechanism that supports a photoconductive sheet.
