Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a film carrier used for positioning an image frame of a photographic film when an image recorded on the photographic film is exposed on photographic paper or the like. The present invention relates to a film carrier capable of recording and reading.

[0002]

2. Description of the Related Art In recent years, an area in which magnetic information can be recorded is provided at a predetermined position of a non-image portion of a photographic film (for example, a negative film), and information when photographing each image frame and information when printing are recorded. Along with that, a proposal has been made to use this information when printing. Along with this,
A method has been proposed in which a negative film is wound on a cartridge (hereinafter referred to as "cartridge") without being cut and returned.

In such a negative film, when the printing process is continuously performed after the developing process, the cartridge and the negative film are loaded into a film carrier as so-called strips in a separated state. It will be loaded together with the film carrier into the film carrier and processed while being pulled out from the cartridge.

By the way, in order to read the magnetic information recorded on the negative film at the time of printing or to record the magnetic information, the magnetic information is read on the film carrier.
A magnetic head (reading head, recording head) for recording may be provided. As a result, if various information is recorded in advance on the negative film, it is possible to read this information recorded on the negative film before printing and change, for example, the print size or improve the tint. it can. Moreover, new information can be further recorded.

In order to read the magnetic information recorded on the negative film or record the magnetic information on the negative film, for example, like the tape recorder, the negative film (magnetic recording portion) is formed on the gap portion of the magnetic head. Need to be pressed with the appropriate force.

In a general tape recorder, the tape is pressed against the magnetic head by a felt pad. However, when a felt-made pad is used when pressing a negative film that handles an image, rubbing dust of the pad may be attached to the image surface to impair print quality. As a mechanism capable of solving such a problem, there is a mechanism in which a negative film is pressed against a magnetic head by a rotating roller (disclosed in FIG. 4 of JP-A-6-95265).

By the way, alignment of the negative film in the width direction is also an important problem, but the center of rotation of the rotary roller is
If it does not pass through the position of the gap of the magnetic head and on the imaginary line perpendicular to the film surface, there are problems that the read signal level from the magnetic head will drop and information cannot be recorded at the normal signal level. Positioning of the roller and the magnetic head is also very important. In particular, a magnetic head for reading requires highly accurate alignment (for example, alignment within about ± 0.3 mm in the transport direction).

In this type of film carrier, since the magnetic head is attached to the lid through various parts, the dimensional error of each part and the mounting error between the parts (for example, mounting screws and mounting It is difficult to align the position of the magnetic head and the rotating roller due to the accumulation of (due to the gap between the holes, etc.), and it is necessary to perform the alignment by moving the individual parts, and it takes time for the adjustment work. There's a problem.

In the film carrier 10 of this embodiment, the magnetic information for each image frame 12A recorded on the negative film 12 sent from the cartridge loading section 32 side onto the transport path 46 of the pedestal section 30 is transferred to the magnetic head section. Thirteen
After being read by the 2,134 reading heads 140, each image frame 12A is arranged at a predetermined position facing the opening 48, and a printing process is performed.

Further, the negative film 12 that has been subjected to the baking process passes through the magnetic head portion 138 and is fed into the film accommodating portion 34. At this time, the recording head 142 of the magnetic head portion 138 newly creates a new magnetic track 20A. In addition to recording magnetic information, it is possible to read the magnetic information recorded by the read head 140 provided on the film accommodating portion 34 side of the recording head 142 and confirm that accurate magnetic information is recorded. Has become.

Further, in the film carrier 10, when the negative film 12 accommodated in the film accommodating section 34 is rewound into the cartridge 14 of the cartridge loading section 32, the recording head 142 of the magnetic head section 134 applies the negative film 12 to the negative film 12. Record magnetic information. At this time,
The magnetic information recorded by the recording head 142 is confirmed by the reading head 140 that contacts the negative film 12 next to the recording head 142.

Although the information at the time of photographing is mainly recorded on the magnetic track 20B facing the magnetic head portion 132, the magnetic information can be rewritten by the recording head 142 of the magnetic head portion 132. At this time, the read head 140 that comes into contact with the negative film 12 next to the recording head 142 can confirm the magnetic information recorded by the recording head 142.

Further, the transport path 46 is provided with LEDs 146 facing the sensor section 136 at both ends and the center in the width direction. When the LED 146 is turned on, light is emitted toward the sensor unit 136, and the light transmitted through the negative film 12 on the transport path 46 reaches the sensor unit 136. The sensor unit 136 detects the perforation 18 and the image from the light of the LED 146 transmitted through the negative film 12, and records a DX code or the like as a bar code on the end of the negative film 12 in the width direction. When this is being done, this DX code is read.

In the film carrier 10, from the perforations 18 detected by the sensor section 136,

In accordance with the result of this determination, frame feed conveyance of the negative film 12, magnetic information reading, and recording timing control are performed.

In the film carrier 10, this L
Even when the negative film 12 accommodated in the film accommodating portion 34 is rewound into the cartridge 14 by the ED 146 and the sensor portion 136, the perforation 18 is detected,
The recording head 142 of the magnetic head unit 134 records magnetic information on the negative film 12, and the reading head 140 controls the timing of reading magnetic information.

On the other hand, a film sensor 148 for detecting passage of the negative film 12 is provided near the transport roller 54 on the cartridge loading section 32 side.

From the film sensor 148, the cartridge loading section 32 or the negative insertion section 66 provided in the housing 64 of the cartridge loading section 32, it is detected whether or not the negative film 12 is inserted into the transport path 46 of the pedestal section 30. It is like this. Therefore, in the film carrier 10, the negative film 12 is detected by the film sensor 148 when the cartridge 14 is not loaded in the cartridge loading section 32 or when the insertion motor 92 is not in operation while the cartridge 14 is loaded. When the passage of the negative film 12 is detected, it is determined that the strip negative film 12 has been inserted, the solenoid 126 is energized to rotate the guide 118, and when the negative film 12 is stored in the baking process, the film storage portion 34 Discharge cover 108
It is designed to be discharged to the upper surface side of.

Next, the operation of this embodiment will be described. (Position Adjustment Method of Negative Film Pressing Device) First, regarding the position adjustment of the negative film pressing device 240 with respect to the read head 140 and the recording head 142, the order of adjustment in the magnetic head portion 132 will be described as a representative. (1) First, the bolt 268 of the negative film pressing device 240 is slightly loosened. (2) Next, the negative film 12 for inspection adjustment on which the test signal is recorded is conveyed to the magnetic tracks 20A and 20B, and the eccentric pin is adjusted with a minus driver so that the output signal from the read head 140 becomes maximum. The position of the support 242 is finely adjusted by rotating 274. (3) Tighten the bolt 268 at the position where the output signal from the read head 140 is maximized to securely fix the support 242.

During the position adjustment, the support 24
2 is pressed against and supported by the pedestal portion 30 by the biasing force of the leaf spring 263, the coil spring 258
The backup roller 144 is pressed against the read head 140 and the recording head 142 with an appropriate pressing force by, so that there is no change in the output signal due to the change in pressing force.

By making the adjustment in this way, the magnetic information on the magnetic tracks 20A and 20B can be reliably read. Also, the magnetic tracks 20A, 20B
It is possible to surely write the magnetic information to. (Method of Processing Negative Film of Strips) When the negative film 12 of strips is processed by the film carrier 10, the negative insertion portion 66 provided in the housing 64 of the cartridge loading portion 32 to the transport path 4 of the pedestal portion 30.
The negative film 12 is directly inserted into 6. When the negative film 12 is thus inserted and the leading edge of the negative film 12 is detected by the film sensor 148, the transport motor 58
Is driven, and the negative film 12 is nipped and conveyed by the conveying roller 54 and the idle roller 56. The transport motor 58 may be driven before the negative film 12 is inserted.

On the other hand, in the film carrier 10, when the film sensor 148 detects the negative film 12, the negative film 12 contained in the cartridge 14 is determined depending on whether the feeding motor 92 of the cartridge loading section 32 is driven or not. If there is, it is determined whether it is the negative film 12 inserted from the negative insertion portion 66, and if it is determined to be the negative film 12 inserted from the negative insertion portion 66, the solenoid 126 of the film accommodating portion 34 is energized, The leading end of the guide 118 is lowered, and the transport path is switched so that the negative film 12 is discharged from the discharge portion of the discharge cover 108. The transfer path of the negative film 12 in the film accommodating section 34 may be switched in advance by operating a predetermined switch. On the other hand, in the pedestal portion 30, while the negative film 12 is being conveyed along the conveying path 46, the magnetic information recorded on the magnetic tracks 20A and 20B of the negative film 12 is read by the read head 140 of the magnetic head portions 132 and 134. While using the sensor unit 136, perforation 1

A baking process is performed based on the magnetic information recorded in A and 20B.

Here, when the image frame 12A of the negative film 12 is opposed to the opening 48 and is stopped, the read head 140 of the magnetic head portions 132 and 134 is moved to the image frame 12A.
Between the magnetic tracks 20A and 20B, the read head 140 contacts the magnetic tracks 20A and 20B when the negative film 12 is being conveyed, so that the magnetic tracks 20A and 20B are recorded. It is possible to accurately and surely read the existing magnetic information.

When the printing process is completed, the negative film 1
2 is sequentially conveyed toward the film accommodating portion 34. The recording head 142 of the magnetic head portion 138 first comes into contact with the magnetic track 20A of the negative film 12 conveyed from the opening portion 48 toward the film accommodating portion 34, and a new recording is completed for the image frame 12A for which the printing process has been completed. While the magnetic information is recorded, it is confirmed by the read head 140 that comes in contact with the recording head 142 that the recording head 142 has accurately recorded the predetermined magnetic information.

Here, when the conveyance of the negative film 12 is stopped, the magnetic track 20 between the image frames 12A is stopped.
The magnetic head portion 13 is provided at a position where A and 20B are not formed.
No. 8 recording head 142 and reading head 140 are located, while the negative film 12 is being conveyed, the magnetic track 20A moves in contact with the recording head 142 and reading head 140, so that the magnetic information is accurately recorded. In addition to being able to record, the recorded magnetic information can be accurately read and confirmed.

In this way, when the negative film 12 having new magnetic information recorded therein is sent to the film accommodating portion 34, it is sent to the upper surface of the discharge cover 108 by the discharge cover 108 and the guides 114 and 118, and directly. ,
The film is taken out from the discharge section 127 of the film accommodating section 34. (Method of processing negative film contained in cartridge)
When the negative film 12 accommodated in the cartridge 14 is printed with this film carrier 10,
The cartridge 14 containing the negative film 12 is attached to the cartridge holder 72, and the cartridge 14 and the cartridge 14 are loaded into the housing 64. After that, the door 22 of the cartridge 14 is opened and the delivery motor 92 is operated, whereby the cartridge 1
The negative film 12 is sent out from 4 to the transport path 46.

In the film carrier 10, the feeding motor 92 is driven in the cartridge loading section 32 to drive the negative film 1
When 2 is fed, the negative film 12 is nipped and conveyed by the conveyance roller 54 and the idle roller 56, magnetic information is read by the reading head 140 of the magnetic heads 132 and 134, and each image frame 12A is sequentially placed in the opening 48. Arrange and burn. At the same time, in the film accommodating section 34, the energization of the solenoid 126 is stopped, and the tip of the guide 118 moves upward and is switched to the transport path to the film winding section 104.

The negative film 12 which has been baked
The magnetic information is not recorded by the magnetic head portion 138, and is conveyed toward the film accommodating portion 34 through the conveying path 46, and wound around the winding shaft 102 to be accommodated.

Here, when the negative film 12 of substantially the entire amount is pulled out from the cartridge 14 and the printing process is completed, the take-up motor 106, the conveyance motor 58, and the delivery motor 92 are reversely driven to move the negative film 12 at a constant speed. Rewind to the cartridge 14. At this time, in the film carrier 10, while detecting the perforation 18A by the sensor unit 136, the predetermined magnetic track 20A is detected.
New magnetic information is recorded by the recording head 142 of the magnetic head portion 134, and at the same time, the magnetic head portion 134 is recorded.
First, the magnetic information recorded by the read head 140 provided on the downstream side of the recording head 142 (in this case, the cartridge loading section 32 side) is confirmed.

As described above, when the negative film 12 pulled out from the cartridge 14 is rewound into the cartridge 14, the negative film 12 is conveyed at a constant speed,
By recording magnetic information at a predetermined position on the negative film 12, accurate and reliable recording of magnetic information on the negative film 12 becomes possible.

Here, the image frame 12 of the negative film 12
When the center interval of A is the dimension X, the magnetic head portion 138

+1) X / 2 (where n is an integer other than 0 and ± 1), and each n is preferably within ± 3 without increasing the size of the film carrier 10. [Second Embodiment] Next, a second embodiment of the present invention will be described. The same parts as those in the first embodiment are designated by the same reference numerals and the description thereof is omitted.

As shown in FIGS. 9 and 10, the support body 242 of the second embodiment is provided with a screw hole 300 parallel to the longitudinal direction of the groove portion 241 on the lower side of the groove portion 241.

A block 302 is fixed to the lower surface of the pedestal portion 30 with a screw (not shown) at a position separated from the support 242 by a predetermined dimension. This block 302 includes support 24
A round hole 304 is formed coaxially with the second screw hole 300.

The adjusting screw 306 is inserted into the round hole 304 from the side opposite to the support 242 side.
The threaded portion 308 is screwed into the screw hole 300 of the support body 242.

The adjusting screw 300 has a non-threaded portion 312 having a predetermined dimension from the head portion 310, and the non-threaded portion 312 has a round hole 30.
It corresponds to 4.

A groove 314 is formed in the non-threaded portion 312. An E-ring 316 is fitted in the groove 314 so that the adjusting screw 300 can only rotate with respect to the block 302 and cannot move in the axial direction.

A coil spring 318 is arranged on the outer periphery of the adjusting screw 306.
Reference numeral 18 presses the block 302 and the support 242 to suppress rattling of the adjusting screw 306.

In this embodiment as well, as in the first embodiment, the leaf spring 263 is disposed below the bottom plate 262, and the leaf spring 263 presses the support body 242 against the pedestal portion 30 with a predetermined force. Has been.

Next, the adjustment order of this embodiment will be described. (1) First, the bolt 268 of the negative film pressing device 240 is slightly loosened. (2) Next, the negative film 12 for inspection adjustment in which the test signal is recorded is conveyed to the magnetic tracks 20A and 20B, and the adjustment screw is adjusted with a flat-blade screwdriver or the like so that the output signal from the read head 140 becomes maximum. The position of the support 242 is finely adjusted by rotating 306. (3) Tighten the bolt 268 at the position where the output signal from the read head 140 is maximized to securely fix the support 242.

As described above, the negative film pressing device 2
By adjusting 40, the magnetic information of the magnetic tracks 20A and 20B can be read reliably as in the first embodiment, and the magnetic tracks 20A and 2B can be read.
It is possible to surely write the magnetic information to 0B.

The operation of each component may be controlled by providing a control unit on the film carrier 10 to control the operation of each component, and the operation may be controlled by a control signal from a printer processor (not shown). You may do it.

When printing is performed, there are simultaneous printing and reprinting. Here, it is conceivable to correct / change the magnetic information recorded by the camera or the like (for example, when the date, title, memo, etc. are put in the magnetic information on the camera side and these are printed on the print). In order to perform such a special thing, the recording head 14 of the magnetic head unit 132 is
There are two. This allows rewriting when the negative film 12 is rewound onto the cartridge 14.

However, since such a thing is judged after observing the finished print (in other words, it cannot be judged without looking at the finished print), the frequency is extremely low as a whole. Further, in general, it is necessary to process a large amount and quickly at a developing place, and it is not preferable to rewrite the magnetic information on the camera side during the process.

Therefore, it can be said that there is almost no need for the recording head 142 and the reading head 140 for rewriting the magnetic information of the magnetic track 20B when a large amount of strips of the negative film 12 are processed. Only possible.

What is possible even in the case of stripping is that the recording head 142 is provided on the opposite side of the magnetic head portion 138.
Also, since the read head 140 is provided, the cost is increased. Since the film carrier 10 of this embodiment is not provided with the recording head 142 and the reading head 140 for rewriting the magnetic information of the magnetic track 20B,
The increase in cost can be suppressed. Note that this is not the case when it is necessary to handle each individually.
