[0002]

2. Description of the Related Art As a means for easily exchanging information in a photographic system, a system in which a substantially transparent magnetic recording layer is provided on the entire back surface of a photographic film and necessary information is directly recorded on the magnetic surface of the film is known as an international system. Application WO-90 / 0
4205, WO-90 / 04214, US Pat. No. 4,965,627, USP-4975.
No. 732, for example.

In magnetic recording / reproduction, the gap (spacing) between the magnetic head and the magnetic surface has a significant effect on the performance, and the magnetic recording of ordinary photographic film is the conventional magnetic tape or disk for computers. It is assumed that the recording density is much lower than that of the device, but even if there is a gap of 1 μm, the read signal amplitude becomes half or less, and the signal output is originally small in a transparent magnetic recording layer with a low density of magnetic recording material. In some cases, it can be fatal.

Therefore, in magnetic recording / reproduction of a photographic film with a magnetic layer, a magnetic head supporting device for ensuring close running between the magnetic surface on the film and the magnetic head is extremely important.

A magnetic head supporting device for a photographic film is disclosed in US Pat. No. 5,048,4836.
P-5041933 and USP-5285325.
Publications and the like are known. Regarding the method of closely contacting the gap of the magnetic head and the magnetic surface of the photographic film in these, the above-mentioned USP-5034836 and US Pat.
In P-5041933, a magnetic head is attached to a guide rod perpendicular to the photographic film surface, the head is pressed against the film surface by a coil spring, and the photographic film is attached to a curved film guide with tension. Has achieved. Further, in USP-5034836, a structure is adopted in which the gap of the magnetic head and the magnetic surface of the film are brought into close contact with each other by pushing from the back surface of the magnetic surface in contact with the gap of the magnetic head with a pad or the like.

However, even if the magnetic head supporting device has an appropriate structure, dust floating in the air adheres to the magnetic surface of the film, abrasion powder on the magnetic surface, and during film production or development processing. It is experienced that when the surface residual material is deposited on the gap of the magnetic head, a gap between the magnetic head and the magnetic surface is generated to prevent stable adhesion and a reproduction error occurs. Even in recording, if the gap becomes large, sufficient magnetic recording may not be possible. Therefore, when defective reproduction occurs, it is necessary to clean the head gap surface each time with a cotton swab and a solvent, or to clean or polish with a cleaning tape contained in the head cleaning cartridge. is there. Further, in order to prevent defective reproduction, maintenance work such as regular cleaning is required.

[0007]

As described above, the dirt on the gap surface of the magnetic head is not constant depending on the state of the film, and cleaning work may be required frequently, resulting in an error during the work of the photo processor. Therefore, the desired photographic processing cannot be performed, and the work efficiency is often deteriorated because the head is cleaned or redone. In view of such a problem, the present invention reduces the time required for maintenance by cleaning the gap surface with high frequency without performing extra work and efficiently cleaning the head surface, and performing magnetic processing for recording or reproduction. It is an object of the present invention to avoid the troubles caused by errors that occur when performing the processing and to efficiently perform the magnetic processing of the photographic film.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Three types of embodiments of the magnetic information processing apparatus of the present invention will be described in detail with reference to FIGS.

[First Embodiment] FIG. 1 is a perspective view of a first embodiment of a magnetic information processing apparatus.

Reference numeral 1 is a film carrier of a negative film printing apparatus, and the structure relating to film printing is not directly related to the present invention, and therefore its explanation is omitted, but it has at least the following structure. That is, a first guide portion 11 and a second guide portion 12 that guide the film F, which is a photographic film, in the traveling direction while restricting the width direction thereof are provided, and are inserted into the first guide portion 11 and the second guide portion 12. First rail 13 and second rail 1 forming a tunnel that regulates the thickness direction of film F
4 is provided on the upper lid 10. Film F
A first conveying roller 15 and a second conveying roller 16 which are conveying means for causing the sheet to travel at a substantially constant speed are provided on the back surface side of the film F, and the upper lid 10 includes the first conveying roller 15 and the second conveying roller 16. A first driven roller 17 and a second driven roller 18 that face each other and sandwich the film F are provided. A transparent magnetic layer is coated on the entire back surface of the film F, and a magnetic head 19 for reproducing magnetic information input to the magnetic layer is provided. Note that only one magnetic head 19 may have the function of the magnetic head.
Furthermore, the magnetic head 19 may record on the magnetic layer of the film F instead of reproducing.

On the right side of such a film carrier 1,
The film F is arranged so as to be fed out from the patrone P by a predetermined amount, and the film F can be fed out to the patrone P for magnetic processing of magnetic recording or reproduction, or the film F after magnetic treatment can be rewound. The motor 21 that rotates forward and reverse is engaged.

On the left side of the film transport table 1, the magnetic head 19 is slid in contact with the magnetic head 19.
A long cleaning tape 3 for cleaning the gap is provided, and most of the cleaning tape 3 is wound inside the cleaning tape storage member 31. A motor 32 is provided in the cleaning tape storage member 31 to feed or rewind the cleaning tape 3. The cleaning tape 3 may be a dry type in the form of a fine polishing tape, or may be a wet type in which a non-woven fabric or the like is attached on a thin film and a cleaning liquid is also used.

The film carrier 1 is not limited to a film carrier for a negative film printing apparatus, and for example, the order information of a customer as magnetic information is recorded or reproduced on the film F. Anything that processes information can be used.

In FIG. 1, the film magnetic surface is on the lower side and the emulsion image is on the upper side, but the film magnetic surface is on the upper side and the emulsion image is on the lower side. You may use the film conveyance stand made into this.

In the above structure, the cleaning tape 3 passes through the second guide portion 12, the second convey roller 16, the magnetic head 19 and the first convey roller 15 on the film conveying table 1, and the leading end thereof is the first guide portion. It is pulled out to position 11. When the film F is fed from the cartridge P by the motor 21 and the leading end of the film F is fed to the position of the leading end of the cleaning tape 3, the film F is stopped manually or by a sensor (not shown) for detecting the film F. Then, in this state, the tip of the film F and the tip of the cleaning tape 3 are attached to, for example, the adhesive tape 4.
To connect. When the adhesive tape 4 is joined, if the joining portion is not joined near the center in the width direction, the adhesive portion of the adhesive tape 4 may come into contact with the magnetic head 19 and stain the magnetic head 19. Further, instead of using the adhesive tape, the ends may be overlapped with each other and bonded by an adhesive, or may be heat-welded for connection.

In this way, after the film F and the cleaning tape 3 are connected, in order to magnetically process the film F, the first transport roller 15 and the second transport roller 16 are rotated to move the film F in the arrow direction. Let it run. At this time, since the cleaning tape 3 slides on the magnetic head 19 before the film F contacts the magnetic head 19,
The gap of the magnetic head 19 is cleaned. Then, the film F slides on the magnetic head 19 to perform a predetermined magnetic treatment. The cleaning tape 3 and the film F that have passed through the second guide portion 12 are wound into the cleaning tape storage member 31 by the rotation of the motor 32.

After the magnetic processing of the film F is completed, the first carrying roller 15, the second carrying roller 16 and the motor 21 are rotated in the reverse direction so that the film F runs in the direction opposite to the arrow and the cartridge P. Roll it up. Also at this time, after the film F has passed the magnetic head 19, the cleaning tape 3 cleans the magnetic head 19 again. If the cleaning tape 3 is provided with a positioning hole 3a at the tip thereof, the photoreflector 35, which is an optical sensor, is provided below the film carrier 1. Therefore, the positioning hole 3a is provided. Can be detected and the film F can be automatically stopped together with the cleaning tape 3.

Since the magnetic treatment and rewinding of the film F have been completed, the adhesive tape 4 or the adhesive is peeled off, and the film F is removed together with the cartridge P. As described above, the connection between the film F and the cleaning tape 3 is temporary and does not require a strong pulling force to separate the films F from each other, so that a strong connection is not required.

Further, the film F and the cleaning tape 3
In connection with the connection and peeling off with, in the present embodiment, a portion on the right side of the first guide portion 11 that is not hidden even when the lid 10 is closed is preferable. Especially, with or without the lid 10, the film F
By connecting the film F and the cleaning tape 3 in the first guide portion 11 that regulates the width direction, the ends in the width direction are aligned with each other, and the connection portion is not caught during traveling.

Further, the film F and the cleaning tape 3
For the connection with, a clip-shaped sandwiching member as shown in FIG. 2 may be used. In the figure, 37 is a sandwiching member, which integrally connects the widthwise central portions of the cleaning tape 3 by adhesion or the like. Then, the center portion in the width direction of the film F is sandwiched by the tip portion 37a. It should be noted that, in order for the sandwiching member 37 to travel smoothly, the traveling portion of the film F of the carrier 1 needs to be configured so that the sandwiching member 37 does not contact. For example, as shown in the cross-sectional view of the first guide portion 11 shown in FIG. 3, the area 11a between the first guide portion 11 and the first rail 13 corresponding to the screen portion are usually arranged so that the screen portion of the film F does not come into sliding contact. The space 13a is a groove which is withdrawn from the film F,
If this groove is formed deeper, the sandwiching member 37 will not abut.

The above film F and cleaning tape 3
With respect to the connection and separation with respect to, as long as the sandwiching member 37 is configured so as to be able to be slightly displaced in the width direction of the cleaning tape 3 or the film F, it is not necessarily connected in the first guide portion 11. The position in the width direction is automatically adjusted so that the guide parts can be passed through without difficulty.

Further, the film F and the cleaning tape 3
The connection and the peeling to and from the unit may be performed manually, or by a robot device that automatically detects the cleaning tape 3 and the leading end of the film F with a photo sensor or the like and automatically connects and separates.

When the cleaning tape 3 slides on the magnetic head 19 many times and the cleaning efficiency deteriorates, the used portion is cut off and the unused cleaning tape 3 is pulled out from the cleaning tape storage member 31 and used. Good. Therefore, the cleaning efficiency can be maintained without much trouble until all the cleaning tapes 3 stored are exhausted. However, when the front end of the cleaning tape 3 is detected by the positioning holes 3a, it is necessary to form the positioning holes 3a in the cleaning tape 3 at a constant pitch.

Further, even when the film F to be processed is stored in the cartridge P and the curl is kept in a strong state, the leading end of the film F is pulled by the cleaning tape 3 and the magnetic head 19 is moved. There is also a side effect of making it easier to pass.

[Second Embodiment] FIG. 4 is a perspective view of a second embodiment of the magnetic information processing apparatus.

In this embodiment, the cleaning tape storage member 31 for winding the cleaning tape 3 and the film F which have run on the film carrier 1 in the above-described first embodiment.
Instead of the above, a space for accommodating them, for example, a tunnel-shaped film accommodating portion 41 having a sufficient margin in the length direction is provided, and the others are the same as those in the first embodiment. Therefore, the same members as those in the first embodiment are designated by the same reference numerals. The film storage portion 41 is arranged on an extension of the film F in the traveling direction of the film transport base 1, and has a radius of 100 m, for example.
The cleaning tape 3 and the film F, which have run on the film carrier 1, can be accommodated without difficulty by bending the arc upward or downward with a gentle arc of m. When the film F is folded downward, even the slightly long film F is naturally accommodated due to its own weight.

In this embodiment, the strip-shaped cleaning tape 3 is used, and after being connected to the film F as in the first embodiment, it is reciprocated on the film carrier 1.
When the cleaning tape 3 and the film F are separated from each other, the cleaning tape 3 is in contact with the gap surface of the magnetic head 19 between the first transport roller 15 and the first driven roller, and the second transport roller 16 It is sandwiched between the second driven roller and the second driven roller, and is held until the film to be processed next is connected, so that it is not displaced.

[Third Embodiment] FIG. 5 is a perspective view of a third embodiment of the magnetic information processing apparatus.

This embodiment differs from the first and second embodiments in that the film F and the cleaning tape 3 are not connected,
As the film F travels back and forth, the cleaning tape 3
Is also reciprocated to clean the magnetic head 19. The same members as those in FIG. 1 are designated by the same reference numerals.

First, at the start of use of the magnetic information processing apparatus in this embodiment, the film F is fed out from the cartridge P arranged near the film F, only the film F is run, and the magnetic head 19 performs a predetermined magnetic treatment. ,
After the film F has passed through the film carrier 1, the film F is formed in the same manner as in the second embodiment.
Store temporarily in. When all the magnetic processing for the film F is completed, the motor 21 is driven by a control circuit (not shown) to rewind the film F into the cartridge P. When the photoreflector 35 detects that the front end of the film F to be rewound has passed, the motor 53 starts to be driven by the control circuit.

The cleaning tape storage member 52 has the long cleaning tape 3 wound inside and is formed integrally with the film storage portion 51. The motor 53 is fixed to a fixing member (not shown), and the screw 54 of the motor shaft is screwed into the cleaning tape housing member 52. Therefore, the rotation of the motor 53 in one direction causes the cleaning tape storage member 52 and the film storage portion 51 to descend, and the rotation of the motor 53 in the other direction causes the cleaning tape storage member 52 and the film storage portion 51 to move up.

When the photo reflector 35 detects that the front end of the film F to be rewound has passed, the cleaning tape storage member 52 is lowered together with the film storage portion 51 by driving the motor 53, and the film F is transferred to the film transport base 1. When the entrance / exit of the cleaning tape 3 coincides with the running part that runs in, the driving of the motor 53 is stopped. Subsequently, the motor 55 is driven to take out the cleaning tape 3 and run on the film transport table 1 to clean the magnetic head 19. When the photoreflector 35 detects the leading end of the cleaning tape 3 that has been fed out, the control circuit stops the rotation of the motor 53.

Next, when a film cartridge P to be magnetically processed is newly mounted, the control circuit issues a reverse rotation command to the motor 55 to rewind the cleaning tape 3 into the cleaning tape housing member 52. At this time, the magnetic head 19 is cleaned again. Then, after a predetermined time, the control circuit commands the motor 21 to feed the film F so as to follow the cleaning tape 3. After the cleaning tape 3 is rewound and passes over the film transport base 1, the control circuit drives the motor 53 to raise the cleaning tape storage member 52, and the film F is transferred to the film running portion of the film transport base 1. To match the doorway,
The film storage unit 51 is raised. And film F
Is repeatedly stored in the film storage portion 51.

In this way, in this embodiment, the magnetic head can be cleaned without connecting each film to the cleaning tape. Further, when the cleaning efficiency of the cleaning tape is lowered after performing a large number of cleanings, the cleaning tape may be cut as it is and the unused cleaning tape may be pulled out.

When the film F is rewound into the cartridge P, the tip of the film F is not detected by the photoreflector 35, but by the magnetic head 19 or a photoreflector newly provided on the film accommodating portion 51 side of the magnetic head 19. It may be detected. By doing so, the cleaning tape 3 can be fed out without leaving a large gap with the film F to be rewound, and the time of one cycle can be shortened.

The film storage portion 41 of the second embodiment and the film storage portion 51 of the third embodiment may be wound by a motor other than the tunnel type shown in the drawing.

[0038]

According to each claim of the present invention, the following effects can be obtained.

(1) When the magnetic surface of the film produces abrasion powder at the magnetic head and other contact portions and is deposited in the gap portion of the magnetic head, a gap is created between the magnetic surface and the gap portion.
It is possible to prevent the efficiency of magnetic recording and reproduction from being deteriorated by cleaning the gap portion with a cleaning tape each time a new film is inserted.

(2) When dust in the air caught by the magnetic surface of the film enters between the magnetic surface and the gap portion, the signal similarly deteriorates. In this case as well, the gap portion is cleaned every time. By doing so, the obstacle can be prevented in advance.

(3) Depending on the surface condition and storage condition of the produced film, a part of the emulsion components may adhere to the magnetic surface on the back side, or a part of the processing agent may remain on the magnetic surface during development processing. However, if these adhere to the gap portion, the signal is deteriorated as in the above case. However, in this case as well, by similarly cleaning the gap portion each time, the obstacle can be prevented beforehand.

(4) Since the head is cleaned every time a new film is inserted as described above, it is not necessary to clean the magnetic head regularly, and maintenance work of the magnetic information processing apparatus is easy. Becomes

In addition to the above effects, in the case of claims 1 and 2,
Since the photographic film and the cleaning tape travel back and forth and both of them always return to the initial position, new photographic film can be repeatedly mounted one after another. In addition, the cleaning tape is attached every time a new photographic film is attached.
Since the magnetic head is cleaned twice when reciprocating, the above obstacle can be eliminated.

In addition to the above effects, in the case of claim 3, the movement of the cleaning tape is limited within the apparatus, so the processing time is shortened.

In addition to the above effects, in the case of the fourth aspect, the cleaning tape and the film can be connected to each other with a handy member.

In addition to the above effects, in the case of claim 5, the cleaning tape and the film can be easily connected.

In addition to the above effects, in the case of the sixth aspect, since the width of the film and the cleaning tape are substantially the same, they are not caught at the seam during running.

In addition to the above effects, in the case of claims 7 and 9,
The magnetically treated film will not get dirty or damaged.

In addition to the above effects, in the case of claim 8, when the cleaning efficiency of the cleaning tape is lowered, the used portion can be cut off and the unused portion can be used.

In addition to the above effects, in the case of the tenth aspect, the displacement of the cleaning tape and the film during the connection is unlikely to occur.

In addition to the above effects, in the case of claims 2 to 10, even when the film wound in the cartridge has a tight curl and the tip portion thereof does not easily pass through the magnetic head portion, the film is connected to the cleaning tape. After passing through the magnetic head, the tip portion can be easily passed.

In addition to the above effects, in the case of the eleventh and twelfth aspects, it is not necessary to connect the film and the cleaning tape.
