Then, the cover 36 is closed and the cartridge 14 containing the negative film 12 is loaded into the cartridge loading portion 32 of the negative carrier 10. On the other hand, when the printing process of the image recorded on the strips negative film 12 is performed, the strips negative film is inserted from the negative insertion portion 66 provided on the upper surface of the housing 64.

After that, the negative film 12 is pulled out from the cartridge 14 and conveyed at a constant speed to be accommodated in the film accommodating portion 34 (outward path). At this time, the position of each image frame 12A is judged from the perforation 18 detected by the optical sensor 136A of the sensor unit 136, and the magnetic track 20 is detected.
The magnetic information about each image frame 12A recorded above is read by the read head 140 of the magnetic head units 132 and 134, and is stored in the printing control unit as the information of the corresponding image frame 12A.

The negative film accommodated in the film accommodating portion 34 is rewound in the cartridge 14 by reversing the conveying direction (return path). At this time, intermittent conveyance is performed, the image frames 12A are sequentially arranged in the opening 48, and the printing operation is performed based on the information of each image frame 12A accumulated in the printing control unit. New magnetic information is added to the recording head 1 of the magnetic head units 132 and 134 for the image frame 12A that has been printed.
Record or modify in place by 42.

Next, the input abnormality detection processing will be described with reference to FIGS. 9 and 10. In step 200 of FIG. 9, the reading repetition number N for confirming the abnormality detection based on the input is set in advance, and in step 202, the value of n which is the actual repetition number is reset (0).

When the value of n is reset, step 20
In 4, the negative film 12 to be printed is set on the negative carrier 10. This is performed by loading the cartridge 14 in which the negative film 12 of interest is loaded into the cartridge loading section 32.

When the negative film 12 is set, the leading end of the negative film 12 is pulled out and guided onto the conveying path 46 in step 206, and is conveyed at a constant speed by the conveying roller 54 on the conveying path 46.

When the negative film 12 is conveyed at a constant speed, in step 208, the read head 140 of the magnetic head units 132 and 134 comes into sliding contact with the magnetic track 20 to read the magnetic information. The magnetic information read by the read head 140 is continuously input to the image sticking control unit, while the input abnormality detection unit 152 monitors the input of information.

When the reading process is started and the magnetic information is input, it is determined in step 210 whether or not the input of the magnetic information is stopped halfway. If the input is not stopped midway, the process returns to step 206, the negative film 12 is conveyed at a constant speed on the conveying path 46, and the reading of magnetic information is continued.

When the magnetic information is not input in the middle of the magnetic information, the determination in step 210 is affirmative and step 2
Moved to 12, the last entered information is negative film 1
It is determined whether or not it is that of the final image frame 12A in the drawing direction of No. 2. If it is the information of the final image frame 12A, the process proceeds to step 214, it is confirmed that the final image frame 12A is positioned in the opening 48, the constant speed conveyance is stopped, and the process is completed.

On the other hand, if the last input information in step 212 is not the final image frame 12A, the determination is negative, and in step 216, an abnormality detection process for detecting the cause of the abnormality causing the input abnormality. Move to.

Next, the abnormality detection processing will be described in detail with reference to FIG. When the process shifts to the input abnormality detection process, in step 300, the constant speed conveyance of the negative film 12 is stopped. When the conveyance is stopped, the image frame 12A that has not been input is specified in step 302. The image frame 12A can be easily specified by the perforation 18.

When the image frame 12A is specified, in step 304, the driving of the feeding motor 58, the feeding motor 92, and the winding motor 106 is switched to reverse the feeding direction, and the negative film 12 is fed backward. The conveyance is stopped when the specified magnetic track 20 of the image frame 12A is conveyed backward and passes the read head 140 of the magnetic head units 132 and 134.

When the reverse transport of the negative film 12 is stopped,
In step 306, the value of n is incremented. When incremented, in step 308, the negative film 12 is transported at a constant speed in the forward transport direction,
The magnetic information on the magnetic track 20 of the image frame 12A specified in step 310 is read again.

When the magnetic information is read, it is determined in step 312 whether the magnetic information is read by the read head 140 and input. If the information has been input, the determination is affirmative and the abnormality detection process ends.

On the other hand, if the magnetic information is not input, the determination is negative, the process proceeds to step 314, the number of repetitions N is compared with the actual number of repetitions n, and the number of the set number of repetitions N is set. If not exceeded, step 3
04, the negative film 12 is conveyed again in the reverse direction,
The reading is repeated until information is input or the set number of repetitions N is exceeded.

No information is input even if the reading is repeated, and if the actual number of repetitions n exceeds the set value N, the sensor 153 causes the head core surface of the reading head 140 to become dirty in step 316. It is judged whether there is. When the dirt is detected, the determination is affirmative and the process proceeds to step 318, where the cleaning lamp 154A is turned on to notify the user that the cleaning process is necessary.

When the cleaning lamp 154A is turned on and the necessity of the cleaning process is notified, step 320 is performed.
At, the negative film 12 drawn onto the transport path 46 is rewound into the cartridge 14. Cartridge 1
The rewinding of No. 4 is performed by driving the winding motor 106.

When the rewinding of the cartridge 14 is completed, the rewound cartridge 14 is taken out from the negative carrier 10 in step 322.

When the cartridge 14 is taken out from the negative carrier 10, the cleaning film 156 is set in step 324. The cleaning film 156 is loaded in the cartridge 14, and the cartridge 14 loaded with the cleaning film 156 is loaded in the cartridge loading unit 32.

When the setting of the cleaning film 156 is completed, in step 326, the negative film 12 is
In the same manner as in the pulling out of the above, the conveyance is carried out at a constant speed while being guided to the conveyance path 46, and is reciprocally conveyed on the conveyance path 46 so that the read head 140 and the recording head 142 slidably contact the head core surface of the recording head 142 for cleaning.

When the cleaning film 156 is conveyed reciprocally and the cleaning is completed, in step 328, the cleaning film 156 is completely rewound on the cartridge 14 and taken out from the negative carrier 10 together with the cartridge 14.

When the cleaning film 156 is taken out, in step 330, the cleaning lamp is turned off to notify the user that the cleaning is completed, and the abnormality detection process is terminated.

On the other hand, if the head core surface is not contaminated in step 316, the determination is negative, and in step 332, the conveyance abnormality warning lamp 154B is turned on and the abnormality detection processing ends.

When the abnormality detection process is completed, the routine proceeds to step 218 in FIG. 9 and it is judged whether or not the reading of the negative film 12 interrupted due to the abnormality is continued. When the information is input in the abnormality detection process or when the cleaning lamp 154A is turned on and the cleaning process is completed, the determination is affirmative because the reading by the negative carrier 10 is in the continuous state, and the process proceeds to step 200. After the shift, the number of repetitions N is set, the actual number of repetitions n is reset (0), and the negative film 12 whose reading has been interrupted is set again on the negative carrier 10 and the reading is restarted.

On the other hand, when the conveyance abnormality warning lamp 154B is lit in the abnormality detection processing, the reading in the negative carrier 10 is not in the continuable state, so the determination is negative and the processing ends.

Therefore, it is possible to detect abnormal transport at an early stage by reading the information with the read head 140, and it is possible to easily remove stains on the head core surfaces of the read head 140 and the recording head 142. Further, since the optical sensors 136A, 136B, and 136C are also arranged on the transport path 46, it is possible to easily find and remove the adhered dirt, like the head core surfaces of the read head 140 and the recording head 142. it can. As a result, the reading by the reading head 140 and the recording by the recording head 142 can be reliably performed, and further, the optical sensor 13
