DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a device for conveying a photosensitive element and an image receiving element in a thermal developing machine in a superimposed state.

Diffusion transfer type thermal development, in which a color image is obtained by separating a silver image and a dye by releasing a diffusible dye through heat development and transferring this dye to an image-receiving element, requires a photosensitive element, an image-receiving element, a There have already been many technical disclosures regarding developing methods and devices, and a typical example is a method in which the surface of the dye fixing layer and the surface of the photosensitive layer are brought together between a pair of rollers that can uniformly heat and apply pressure. This is carried out by passing an image receiving element and a heat-developable photosensitive element overlapping each other.

Next, both overlapping elements are uniformly heated and thermally developed, and the dye released from the heat-developable photosensitive element is transferred to the dye-fixing layer by the heat development, and then the two sheets described above are peeled off. An image can be formed on the image-receiving element.

In this method, when thermal development transfer is carried out between a superposed photosensitive element and an image-receiving element, it is necessary to maintain the superposed state for a required period of time. It is thought that it will pass.

However, in this method, the photosensitive element and the image receiving element pass in a straight line without bending, so at the contact position of the input belt wheel (roller), both elements are strongly pressed by the pressing force of the belt wheel. However, once the belt passes through this area, only the pressure force associated with the tension of the belt remains and the pressure force is weak, and in the area up to the belt pulley on the exit side, the adhesion between the two elements is poor and uneven transfer tends to occur. . Furthermore, since both elements are fed and moved linearly, there is a risk that gripping failures or errors may occur on the entry side.

On the other hand, in order to shorten the height of the device, it is conceivable to arrange both belts horizontally and reduce the diameter of the belt sheave, but in order to ensure running stability of the belt, it is necessary to reduce the diameter of the belt sheave. There are limits to this, and it has therefore been difficult to reduce the height of the device.

Means for Solving Problem C] The above purpose is to form a pair of belt feeding mechanisms in which healds are wound between belt wheels on the input side and output side, and to place a photosensitive element and an image receiving element between each belt in an overlapping state. In a device for conveying with , the angle formed by the line connecting the centers of the inlet belt wheels of both belt mechanisms and the cotton connecting the centers of the outlet belt wheels, when taken counterclockwise and clockwise, respectively, is 80° to -80°. is achieved.

Therefore, the photosensitive element and the light receiving element are not fed in a straight line, but are fed and discharged while being curved at the entrance and exit sides. Therefore, the reaction force of both elements due to bending brings them into close contact with each other, and the occurrence of uneven transfer due to insufficient adhesion is prevented. Also, as is clear from FIGS. 1 to 4, in the overlapping region from the inlet to the outlet, both belts 3.6 are pressed against the belt pulley 4.5 due to tension. The area becomes longer, and the adhesion between the belts 3 and 6 also improves in this aspect. Incidentally, in conventional examples in which the inlet belt pulley and the outlet belt pulley are placed at the same position in the conveying direction in order to convey linearly, both elements are only linearly in close contact at the inlet and outlet positions, and their In the region between, there is no action from the belt pulley, and only the adhesion force associated with the tension of the belt pulley is applied.

The belt that can be used in the present invention is a heat-resistant belt that can withstand the maximum temperature of thermal development, and a belt that has tension resistance that can withstand the required pressing force. Preferably, a metal belt such as stainless steel, or a carbon-containing silicone rubber or fluororubber belt with heat-resistant fiber as the core material is used, and the contact surface with each element is preferably a smooth surface to improve adhesion. .

Further, as shown in FIGS. 1 to 4, ZBAC=α and :ABD=β are 80° to −80°, more preferably 80° to −45°, particularly preferably 45° to −45°.
It is said that If the positive angle is large, the bending will be small and the conveyance will be close to linear, making it impossible to achieve the objectives of improving the adhesion of each element and lowering the height of the device. Further, similar results can be obtained even if the negative angle becomes larger on the negative side than the above value. If the negative angle is -135°, for example, it is effective for improving adhesion, but it becomes difficult to supply both elements to the gap between the entrance belt wheels, and the addition of the guide roller group increases the height of the device. On the contrary, this results in higher prices.

The diameter of the belt pulley is related to the biting of both elements and running stability, and also affects the height of the device, so it is generally 1 to 30 mm.
