Occurs. The negative film F is transported by an arbitrary amount by the rotation of the feed rollers 68, 72, 88.
Then, the desired image frame is arranged on the optical axis P. In this case, the negative film F
-By reading the code B, an arbitrary image frame is stopped on the optical axis P,
Can correct the printing condition of the stopped image frame. Here is negative film F
Is pressed by guide blocks 98 and 102 in the direction where both ends in the width direction approach each other.
Because of the force, the curl in the width direction is forcibly generated, and as shown in FIG.
The front and back surfaces at both ends in the direction are sandwiched by the inclined surfaces 104A and 106A.
, The bar code B corresponds to the light source 94 and the sensor 96 without fail,
It is accurately read by the sensor 96. In addition, the width of the negative film F
The image part in the middle part of the direction is not in contact with the guide surface by the notch escape parts 104 and 106
As a result, the image is not damaged. As shown in FIG. 2, the notch detecting pin 162 is connected to the notch N of the negative film F.
Since it is urged into the T by the urging force of the torsion coil spring 174,
Before the center of the image frame reaches the optical axis P, the notch NT of the film is moved to the limit switch 17.
2 to control the feed amount of the feed rollers 68, 72, 88 thereafter.
As a result, the image plane is reliably stopped on the optical axis P. In particular, since the widened portion 182 is formed on the downstream side of the optical axis P, the negative film F
To automatically stop at the optical axis P position and correct the movement amount by performing manual feed
In this case, accurate positioning is possible. In other words, a sp
If the rice tape SP is present, the splice tape SP
When the subsequent image frame is stopped on the optical axis P, the splice tape SP and the side of the concave portion 22 are used.
The fine movement adjustment of the conveyance is hindered by the frictional force between the widening portion 182 and the surface.
Can smoothly guide the substantial width dimension increase by the splice tape SP.
The image can be actually stopped on the optical axis P. At the time of printing, the attracting plate 62 is attracted by the excitation of the solenoid 56, so that the seventh
As shown in the figure, the pressing plate 46 is pressed into the concave portion 22, and the pressing plate 66
Both ends in the width direction of the negative film F on the optical axis P are pressed against the bottom surface of the concave portion 22 by the strong urging force of the spring 70. Print the image not shown here at the printing destination from the light source not shown here
Bake on paper. At the time of the pressing operation of the pressing plate 46 at the time of this printing, the negative film F is already in the concave portion.
Since the negative film F is arranged in a flat shape on the bottom surface of the film 22, the negative film F may be damaged or broken.
Will not occur. When the printing is completed, the energization of the solenoid 56 is stopped, and the pressing plate 46 is turned off as shown in FIG.
The negative film F is raised again until the pressing force by the pressing plate 66 is weakened.
The sheet is fed in the direction of arrow A by the driving force of the feed rollers 68 and 72. For this reason
The negative film F enters the film carrier 188, and the lower guide plate 196,
It is reversed and passed through the space between the upper guide plates 198 to work in the direction of arrow D.
Negative film F is not needed due to its longitudinal curl because it is sent to the dealer's hand.
The operator quickly removes the negative film F without returning to the vicinity of the optical axis P,
Scratches can be prevented. The negative film F passes through the film carrier 188.
Also, when the guide portion 208 is in contact with the film edge, the narrow portion 208B comes into contact with the film edge.
The middle portion in the film width direction is separated from the widened portion 208A, and the image form of the negative film F is formed.
Damage to the surface is prevented. In the above embodiment, notches NT are formed at both ends in the width direction of the negative film F.
The notch NT is provided only at one end in the width direction of the negative film F.
It is applicable even if it is. [Effect of the Invention] Since the present invention has the above configuration, it is not necessary to make the sensor follow the end of the film.
Instead, the end of the film moves by following the guide means, and
It has an excellent effect of reading symbols such as codes.
