The exposure section film transport unit U2 has the outer shape shown in FIG. The internal configuration and operation of the film transport unit U2 for the exposure unit are almost the same as the internal configuration of the film transport unit U1 for the scanner unit,
Exposure unit film transport unit U2 schematically shown in FIG.
The transport means N for transporting the film 2 has the same configuration. A different configuration is a negative mask configuration. As the mask 88 of the film transport unit U1 for the scanner unit, a mask having an opening 88a corresponding to the size of the screen of the full-size film 2 is fixedly installed, whereas the mask 88 of the film transport unit U2 for the exposure unit is fixed. However, the difference is that the size of the opening can be changed corresponding to a full size, a half size, a panorama size, or the like having different printing regions. In the state where the full-size film 2 is located on the negative mask 31,
Whether or not the screen portion of the film 2, that is, the frame 2a is within the opening 31a of the negative mask 31, determines whether or not the film 2 has stopped at an appropriate stop position.

The film transport unit U1 for the scanner unit and the film transport unit U2 for the exposure unit are usually used by being installed on a support 40 in the state shown in FIG. FIG.
In the installation state shown in FIG. 5, the opening 30 of the film transport unit U1 for the scanner unit is located on the optical axis of the irradiation light of the light source 50 of the scanner unit SC, and the film transport unit U2 for the exposure unit
The opening 88a of the mask 88 is located on the optical axis of the irradiation light from the exposure light source 60, and the scanner unit S
It is in a set state where it is set at the film transport position of C and the exposure unit EX. In this set state, the film 2 transport path of the film transport unit U1 for the scanner unit and the film transport unit U2 for the exposure unit are connected in series.

When the film transport unit U1 for the scanner unit and the film transport unit U2 for the exposure unit are arranged in the state shown in FIG. 5, when the film 2 is inserted into the film transport unit U1 for the scanner unit, the scanner unit. S
The image information of the film 2 is sequentially read by the image sensor 51 of C, and the film 2 from which the reading of the image information has been completed is directly inserted into the film transport unit U2 for an exposure unit, and is sequentially subjected to the printing exposure processing.

Next, the mechanism of the film stop position checking section of the present invention will be described in detail with reference to FIGS. 7 and 8, the light transmitted from the light source 50 and passing through the mirror tunnel 53 and the diffuser 99 is transmitted through the aperture 30.
, And the image information of the film 2 positioned at the opening 30 is read by the image sensor 51. The light that has passed through the mirror tunnel 53 and the diffuser 99 is uniformly mixed and has no directivity. The diffuser 99 is provided at the exit of the mirror tunnel 53 and has a function of diffusing light.

Part of the light passing through the mirror tunnel 53 is reflected by the reflection plate 97 and is introduced into the viewer 96. The light reflected by the reflection plate 97 passes through the film 2, passes through a sheet 98 provided immediately above the film 2, and reaches a viewer 96. That is, the reflection plate 97 functions as an introduction unit that introduces the light passing through the mirror tunnel 53 to the second film stop position confirmation unit. The sheet 98 is formed of, for example, a transparent resin such as polycarbonate. Line 98a is sheet 9
This line 98 is formed on the surface 8 by embossing or printing.
The stop position of the frame of the film 2 is confirmed by aligning a with the edge of the frame of the film 2. This line 98
“a” indicates an appropriate position of the edge of the frame of the film 2. That is, the line 98a functions as a second film stop position confirmation unit.

The opening 30 has a rectangular shape corresponding to the size of the frame of the film 2. The upstream edge 30 a and the downstream edge 30 orthogonal to the film transport direction of the opening 30.
The stop position of the frame of the film 2 is confirmed by aligning b with the edge of the frame of the film 2. The upstream edge 30a and the downstream edge 30b indicate appropriate positions of the edge of the frame of the film 2. That is, the upstream edge 30
a and the downstream edge 30b each function as a first film stop position confirmation unit. Next, the dimensional relationship between the position of the frame of the film 2 and the first and second film stop position confirmation units will be described with reference to FIG.

The frames 2a of the film 2 are arranged at substantially the same pitch P, and the dimensions of the so-called snake portion between the frames 2a are also substantially S. Here, the distance X1 between the upstream edge 30a and the line 98a is set equal to the pitch P of the pieces. That is, X1 = P × N (N
= 1), and X1 is set to be an integral multiple of P. The reason why X1 is set to an integral multiple of P is that the frames 2a of the film 2 are arranged at substantially equal intervals. At the opening 30, the stop of the frame 2a of the film 2 is confirmed at both the upstream edge 30a and the downstream edge 30b. In the viewer section 96, the line 98a is aligned with the image edge on the upstream side of the frame 2a of the film 2.

Next, the operation for confirming the stop of the frame 2a of the film 2 will be described. When the film 2 is inserted into the scanner unit film transport unit U1, the film 2 is transported by the drive rollers 80a, 80b, 80c, 80d, and 80e. With respect to the frame of the transported film 2, the edge portion of the frame is detected by the image detection optical sensor 87, and based on the detected information, the frame of the film 2 is positioned in the mask 88 (the opening 30). I have. Here, the edge detection of the frame of the film 2 will be described with reference to FIG.

The image detecting optical sensor 87 is, for example, as shown in FIG.
As shown in FIG.
The frames A, 2B, 2C, 2E, and 2F are photographed under standard exposure conditions and are arranged at substantially the same pitch. The 2D frame has a density around the frame and a snake around the frame due to insufficient exposure. The density difference from the density of the portion is not clear. Therefore, when such a film 2 is to be detected and the amount of transmitted light is measured along the two-dot chain line H, the image detection sensor 87 outputs a signal shown in FIG.

The detection information of the image detection optical sensor 87 is sent to the controller CO, and the controller CO
The signal transmitted by the reference value indicated by the straight line I in (b) is obtained by converting the transmitted light amount below the reference value, that is, the transmission density above the reference value, to the “L” level, The signal is binarized to an “H” level indicating that the transmission density is equal to or less than the value, thereby obtaining a signal shown in FIG. In the signal shown in FIG. 11C, frames 2A, 2B, 2C, 2E, and 2F photographed under standard exposure conditions
Although it has a predetermined width W0 corresponding to the pitch P at which the frames are arranged, the density difference between the density of the peripheral portion of the frame and the density of the snake surrounding the frame is not clear due to insufficient exposure. In the pieces, the width W1 of the "L" level is smaller than the width W0. Therefore, when trying to position a frame whose edge portion is unclear as in 2D at the processing position based on the signal of FIG. 11C, the probability that the frame of the film 2 will not be accurately positioned at the processing position increases. Would. In such a case, it is particularly necessary to confirm the stop position of the frame of the film 2.

11A, 2A, 2B, 2C, 2E,
For a frame having a clear edge portion such as 2F, the stop position of the frame of the film 2 can be confirmed using the upstream edge 30a and the downstream edge 30b of the opening 30. If the edge of the frame of the film 2 and the upstream edge 30a or the downstream edge 30b are displaced in the transport direction, that is, it can be visually recognized that the frame of the film 2 is not accurately stopped at the processing position. By pressing the key H shown in FIG. 8, the film 2 is conveyed to position the frame of the film 2 at the correct processing position. Then, when the frame of the film 2 has been accurately positioned, a process of reading image information by the image sensor 51 is performed.

In the case of a frame such as 2D shown in FIG.
It is difficult to confirm the stop of the piece. In such a case, the stop of the frame of the film 2 is confirmed using the viewer section 96. For example, when the piece 2D is positioned at the processing position, the piece 2D is positioned using the adjacent piece 2C on the upstream side. That is, piece 2C
And the line 98a provided in the viewer section 96 may be aligned. Viewer 96
In the case where the line 98a and the edge portion of the frame C are displaced in the transport direction, the operation using the key H is performed as described above.

As described above, since a plurality of film stop position confirmation units are provided in the film transport unit U1 for the scanner unit, the stop of the film is confirmed by one or both of the film stop position confirmation units. It became possible. When the stop of the film is confirmed in the film transport unit U2 for the exposure unit, the stop of the film can be confirmed in the same manner as in the case of the film transport unit U1 for the scanner unit.
