ーズに印画紙１を搬送することができる。Therefore, the sheet-shaped photographic paper 1 conveyed from the conveyance roller 5 of the high-speed conveyance section 3 is transferred to the low-speed conveyance section 4! Before being inserted between the two feed rollers 9, it is inserted between the presser rollers 30. Due to the conveying force of the photographic paper 1, the lower pressing roller 30 is pressed against the spring 3.
1, the photographic paper 1 is held between the presser rollers 30. Therefore, when the transport speed ratio between the high-speed transport section 3 and the low-speed transport section 4 is large, the trailing end of the photographic paper 1 is moved at a high speed while the leading edge of the photographic paper 1 on the low-speed transport section 4 side is bitten by a small amount. This prevents the photographic paper 1 from coming off the conveyance roller 5 of the conveyance section 3, eliminates troubles due to poor feeding of the photographic paper 1, and allows the photographic paper 1 to be conveyed smoothly.

ムすることがてきる。[Effects of the Invention] As described above, the invention according to claim 1 provides that after the sheet-shaped photographic paper conveyed through each conveyance line is inserted into the high-speed conveyance section,
The leading edge of the sheet of photographic paper is inserted from the high-speed conveyance unit into the low-speed conveyance unit via an accumulation unit having a movable guide, and the detection means detects that the leading edge of the sheet-like photographic paper is conveyed to the low-speed conveyance unit; Based on this detection signal, the movable guide of the accumulation section is released at the timing when the photographic paper is conveyed from the plurality of conveyance lines to the low-speed conveyance section. It is possible to absorb and accumulate the difference in paper conveyance speed depending on the photographic paper being conveyed.

速度調整も不要となり、構造が簡単で安価になる。Therefore, even when sheets of photographic paper in multiple transport rows are simultaneously transported and accumulated, the transport speed in each transport row is constant in the high-speed transport section and the low-speed transport section, and the sheets of photographic paper in each transport row are The relative positional relationship of the photographic papers remains unchanged. Therefore, there is no need to adjust the delivery timing to align the sheets of photographic paper, or there is no need for intermittent operation or speed adjustment, resulting in a simple and inexpensive structure.

紙のアキュームができる。In addition, by providing movable guides that operate independently according to multiple conveyance lines, there are fewer restrictions such as the width and length of sheet-shaped photographic paper, and it is possible to accumulate by operating the movable guide. Furthermore, since the accumulation can be performed at intervals shorter than the length of a sheet of photographic paper, the apparatus can be made more compact. Also, it is possible to accumulate photographic paper transported in different numbers of rows without changing the structure.

れる。Further, in the invention according to claim 2, the sheet-shaped photographic paper is carried into the low-speed conveyance section by intersecting the photographic paper conveyance surface of the low-speed conveyance section and the photographic paper conveyance surface of the high-speed conveyance section. When the photographic paper is bent in one direction and transported smoothly, the rear end of the photographic paper tilts toward the open movable guide, and the rear end of the photographic paper is transported smoothly without contacting the movable guide. .

Before inserting the photographic paper into the paper, it is clamped and securely holds the sheet of photographic paper, so when the movable guide is released during high-speed conveyance, it can be prevented from coming off, and there is no trouble caused by poor conveyance of the photographic paper. It is necessary to transport photographic paper.
