There is. In addition, the printing conditions such as AF information of slide film 1 stored in magazine 2 are as follows.
Before storing the slide film 1 in the magazine 2, it is measured in advance using a separate optical system, and the printing conditions are stored in the magazine 2 or in a memory outside the printer. transmission. Furthermore, the transport from the transport section 11 to the print stand 14 and the transport from the printer stand 14 to the transport section 16 are performed by a print transport mechanism 20, which will be described later.

In such a configuration, the slide film 1 is taken out from the magazine 2 and transferred to the M
The slide film 1 finally reaches the top of the print stand 14 by the print transport mechanism 20. Here, the printing conditions of the slide film 1 stored in the magazine 2 have been measured in advance, and when the slide film is input to the block 10, the print conditions corresponding to the input slide film 1 are stored in the printer 10 from the memory. transmitted to. Therefore, the AF mechanism 17 moves the print table 14 up and down in advance according to the transmitted AF information, and when the slide film 1 is conveyed from the conveyance section 11 and reaches the print table 14, this conveyance Slide film 1
The print stand 14 has already been positioned at the focal point. Then, the slide film placed on the printing table 14 is separately positioned at suitable front, rear, left, and right printing positions for printing, and then printed according to the transmitted printing conditions. As a result, at the same time as the slide film 1 is conveyed to the printing table 14, focused printing can be performed at high speed by the printing mechanism 13 under pre-measured printing conditions. In this way,
After printing on the photographic paper 12 is completed, the printed slide film 1 is conveyed to the conveyance section 16 by the print conveyance mechanism 20, where it is conveyed in the N direction and stored in the magazine 3. Become.

The present invention relates to the structure of the transport mechanism of the transport sections 11 and 16 in the slide film printer 10 as described above.

FIGS. 2A and 2B show the drive section of the slide film transport mechanism according to the present invention, and show a rotating wheel 10 connected to a rotational drive source such as a motor.
1 and 102, and these rotating wheels 101 and 10
Teeth 103 for chain engagement are carved on the outer circumferential surface of 2. A chain 104 as a transmission means, the details of which are shown in FIG. Rectangular parallelepiped pushing members 105 are attached to the slide film 104 at intervals slightly wider than the width of the slide film 1. For example, by rotating a motor connected to the rotation 106 of the drive wheel 101, the chain 104 is moved in one direction. It is now being moved in the direction of The rotating wheels 101, 102, chain 104, etc. form an endless circulating body. As shown in FIG. 4, such a drive unit includes a pair of guide members 110 and 111 provided facing each other along the conveying direction.
The guide members 110 and 111 have cutouts 110A and 111 arranged between the guide members 110 and 111 so that both ends of the slide film 1 to be conveyed are placed on the opposite upper sides of the guide members 110 and 111 to guide the conveyance direction. 111A is provided. In addition, the upper surface of the chain 104 of the driving section and the upper surfaces of the notches 110A and 111A are leveled so that the upper surface of the chain 104 is slightly lowered so that it does not come into contact with the slide.

In such a structure, the conveying unit 16 has a driving wheel 101 driven by a motor through a rotating shaft 106.
It is always moved in one direction (M direction) by the rotation of the printer 1 from the magazine 2.
The slide film 1 inputted to the chain 10 is moved in one direction as shown in FIG.
It is placed on top of 4. Here, since the chain 104 is provided with pushing members 105 at intervals wider than the width of the slide film 1, the slide film 1 comes into contact with the pushing members 105 and is pushed in the moving direction of the chain 104. It will be moved while doing so. In this case, since guide members 110 and 111 are disposed on both sides of the chain 104, both ends of the slide film 1 are connected to the notch 11.
The slide film 1 slides on 0A and 111A, and is smoothly conveyed in the M direction as the chain 104 moves. FIG. 5 schematically shows the situation. As a result, in the printing system shown in FIG. 1, the slide film 1 input from the magazine 2 is conveyed toward the print section of the print table 14, and after being printed in the print section, the printed film is also conveyed in the same manner. At the section 16, it is transported in the N direction and stored in the magazine 3. Note that the pushing member 105 can provide a reliable moving force to each slide film without damaging the slide film 1, and does not block the optical axis in the print section, even when intense intermittent driving is performed. It has the advantage that the slide films do not overlap each other and can be easily transferred between the previous and previous processes.

On the other hand, FIG. 6 shows a print conveyance mechanism 20 for the slide film disposed in the print section, that is, a conveyance mechanism for the slide film 1 on the print stand 14. Furthermore, Fig. 7 schematically shows the cross-sectional structure taken along line X-X in Fig. 6, and Fig. 8 schematically shows the cross-sectional structure taken along Y-Y in Fig. 6. light source 15
A pair of guide members 201 and 202 are arranged along the conveyance direction of the slide film 1 with the guide members 201 and 202 separated from each other. Cutouts 201A and 202A are provided at upper opposing positions of the guide members 201 and 202 for placing both ends of the slide film 1. and 202A. And, on the guide member 201 side, there are 4
The driving wheels 203 to 206 are the guide member 201,
The driving wheels 203 to
A chain 207 as described above is wound around the chain 206 . Drive wheels 203-206, chain 20
7 magnitude forms an endless circulation body. chain 20
Pushing arms 210 are mounted horizontally and facing outward at intervals wider than the width of the slide film 1, and as the chain 207 moves, the pushing arms 210 move in one direction Q.
It is starting to move to . Moreover, this pushing arm 210 has a pushing part 211 protruding downward at its end.
The bottom surface level of this pushing part 211 almost matches the top surface level of the notches 201A and 202A of the guide members 201 and 202, so that when the pushing arm 210 moves, the pushing part 211
The side surface of slide film 1 is adapted to push the rear end of slide film 1 placed on notches 201A and 202A of guide members 201 and 202. The printing section is located in the middle of the conveyance of the slide film 1, so that the printing stand 14 and the AF mechanism 17 can perform predetermined operations above the light source 15.

In such a configuration, the slide film 1 conveyed from the conveyance section 11 is placed on the guide members 201 and 202 as shown in 1A in FIG. 6, so that the drive wheels 203 to 206 are rotated by the motor. By doing so, the chain 207 is moved in the Q direction, and the front surface of the pushing part 211 of the pushing arm 210 attached to the chain 207 comes into contact with the left end of the slide film 1A. As a result, the slide film 1A slides on the guide members 201 and 202 as the pushing arm 210 moves. When the slide film 1A conveyed in this way comes to the optical axis 15, its movement is temporarily stopped at 1B, and after the above-described predetermined printing operation is completed, the motor is driven again, and then the next The slide film 1A located at the position to be printed is conveyed to the printing position. By repeating this operation sequentially, the slide film is transferred to the transport section 1.
1, the print table 14 is moved to the transport section 16. In this case, the interval between the pushing arms 210 is wider than the width of the slide film 1, and the slide film 1 is designed to slide on the notches 201 and 202A of the guide members 201 and 202, so that the pushing arm 210 is The movement of the slide film 1 by pushing the arm 210 can be performed stably,
The slide film 1 can be moved smoothly. Further, if the slide film 1 can be transported by the transport section 11 to the position shown in 1A in FIG. 6 while the print transport section 20 is stopped, that is, during exposure, cycle time loss can be reduced. It becomes possible.

Next, the transfer of the slide film 1 between the conveying section 11 and the print conveying mechanism 20, and between the print conveying mechanism 20 and the conveying section 16 will be described with reference to FIG.

The slide film 1 conveyed in the M direction from the conveyance section 11 is moved to the driving wheel 1 at the final end of the conveyance section 11.
02 to the P1 position, and this position P
1 serves as a takeover section with the print transport mechanism 20. In this way, when the slide film transported from the transport section 11 is stopped at the P1 position, the pushing arm 210A rotated by the chain 207 moves the slide film 1C
The side of the left end of the arm can be pushed, and the pushing arm 2
As the slide film 10A moves, the slide film 1C also slides on the guide members 201 and 202 in the Q direction. After stopping at the position of the light source 15 and printing, the printed slide film is further conveyed to the right, but the final position where the slide film 1D is conveyed to the right by the pushing arm 210B is , which is the P2 position in FIG. Therefore, if this P2 position is set as the transfer point with the conveying section 16, the slide film 1D conveyed to P2 by the pushing arm 210B is transferred to the pushing member 105 attached to the chain 104 of the conveying section 16. Thereafter, as the chain 104 moves in the conveyance section 16, the slide film 1 can be engaged with the slide film 1.
It becomes possible to transport D in the N direction. Here, since the pushing arm 210 of the print conveyance mechanism 20 has a pushing part 211 whose tip protrudes downward, it is necessary to prevent it from colliding with the guide members 110 and 201. A place through which the pushing part 211 of the pushing arm 210 passes during movement is cut out. When the slide film is placed on the print stand 14, the print stand 14 is moved up and down to focus, but other members do not move up and down. The vertical movement for focusing is about 1 mm at most, so there is no need to move other members up and down, and if the print table 14 is sloped or rounded at the front and back, no problem will occur.

In addition, in the above-mentioned embodiment, the drive system for the slide films of the conveyance units 11 and 16 is performed using one chain, but it is also possible to drive the slide films by arranging two or three chains in parallel. It's okay.
In addition, the number of drive wheels in the print conveyance mechanism 20 is 4.
However, the number of drive wheels may be 2 or more, and similarly, the number of drive wheels of the conveyance sections 11 and 16 is 2 each, but this number may also be 2 or more. can. Furthermore, in the above-described embodiment, the slide film is directly exchanged between the conveyance section 11 and the print conveyance mechanism 20, and between the print conveyance mechanism 20 and the conveyance section 16, but during this time, the right side (M, Q, N direction)
It is also possible to provide a moving belt, roller, etc. to facilitate the transfer.
In the above embodiment, a pushing member and a pushing arm are attached to the chain to push the slide film, but it is also possible to attach it to a transmission means such as a belt or rope for conveyance.
