2. Description of the Related Art A conventional portable video camera has a built-in recording / reproducing function and is very expensive. It also requires a large weight and a large power supply capacity. So, even if you don't own a video camera,
It has been proposed to use the video camera by changing the sales concept and introducing a rental system.

However, in the case of the rental system, since the video camera itself is expensive, a complicated contract is required, and further, when the user returns the video camera, it needs to be returned to the borrowed store. There is.

Therefore, the applicant of the present application has proposed a new type of disposable video camera and its distribution system.
FIG. 18 shows the distribution route. First, the camera is reused and used. Cameras are bought by users at retail stores. The user makes a recording and deposits the recorded camera at the copying agency. The reproduction device is installed at the copying agency. The copying agency receives the recorded camera from the user, dubs the contents of the recorded tape, and returns the video tape cassette to the user. The used camera is
Brought to the manufacturer's factory. At the factory, the magnetic tape is replaced or erased, rewound, the battery is replaced or recharged, the outer case is attached, and the camera is restored to its original state. Of course, a function check is also performed to see if it operates normally. The restored camera is wholesaled to the retail store through the sales department. The camera is reused by repeating this cycle. However, the camera may encounter loss, loss, theft, etc. in the distribution route. So as a camera,
It is desirable to be as inexpensive as possible. In this way, complicated contract work is not required unlike the camera rental business. Then, a new type of video camera rental business that is disposable can be performed, and for a user who does not frequently take a picture with a camera, it is possible to obtain an advantage of economical efficiency and an advantage such as easy camera purchase at a travel destination.

[0005]

A camera for recording images should be as small and light as possible so that it can be conveniently carried, and its internal structure should be simplified so that it can be used in a harsh environment such as outdoors, and should have a mechanical strength. Increased reliability is desired. Furthermore, it is desired to reduce the power consumption of the camera and lengthen continuous shooting. To this end, in the case of a camera / playback device detachable type image recording / playback device, the internal configuration of the camera is limited to the minimum necessary for shooting, and the playback-related parts (playback device) are usually installed on a desk or a rack. It is preferable to use it. Further, by simplifying the constituent elements of the camera and limiting the unit price to the limit, the damage due to the loss / damage of the camera in the camera rental business is reduced. Furthermore, in the maintenance, management, and handling of recycling operations, a device that is as inexpensive and simple as possible is desired. [A] Here, focusing on the structure of the tape tension generating portion, a type that applies constant friction to the supply reel or a tension regulator type that uses a tension guide and a band brake is mainly used. However, the former has a problem that the tape tension changes depending on the reel winding diameter, and the latter has a problem that the structure is complicated and the cost is high.

Therefore, an object of the present invention is to provide a device which can keep the tape tension constant irrespective of the reel winding diameter and has a simple structure and is inexpensive. [B] In the conventional image recording / reproducing apparatus, it was necessary to provide a dew condensation sensor and a heater to prevent the tape from sticking to the cylinder. As a method of absorbing moisture from the camera, there is a method of putting a moisture absorbent into the camera, such as a vehicle-mounted rear monitoring camera. By using this method, it is possible to absorb moisture in the camera at low cost without providing a condensation sensor and a heater. However, in the case of the camera used in the distribution channel as described above, it is necessary to replace the hygroscopic material when recycling, which increases the cost.

[0007] Therefore, an object of the present invention is to provide a device which can easily replace a hygroscopic material or an acid-absorbing material and is advantageous for recycling work. [C] When using the camera by recycling, it is necessary to check the tape, mechanism, circuit, battery, etc. for defects. If it takes time and labor to perform these checks, the cost for recycling will be high.

[0008] Therefore, it is an object of the present invention to provide an apparatus which can eliminate the inspection step in recycling work, is convenient in terms of management, and is advantageous in terms of work cost. [D] At the dubbing agency, it is desired that the handling be convenient. For example, in the case of a system that is mounted on the playback device except for the outer case, the camera may be damaged if handled by an unfamiliar person during the work. Further, in the case of the camera using the above-mentioned distribution channel, a dubbing process is necessary, but it is more suitable for the user to perform the dubbing at a high speed and immediately. Therefore, it is an object of the present invention to provide a method which is easy to handle and which allows dubbing of a magnetic tape that has been photographed to be obtained in a short time.

[0009]

[0010]

[A] By the above means, a tension regulator that keeps the tape tension constant from the beginning to the end of the tape winding of the reel can be realized with a simple structure. [B] By the above means, the hygroscopic material and the acid absorbing material can be exchanged only by replacing the outer case of the camera, and the workability in the factory is improved.

6 and 7 show the characteristic portion [A] of the apparatus of the present invention. That is, focusing on the structure of the conventional tape tension generating unit, the type that applies constant friction to the supply side reel or the tension regulator type that uses a tension guide and a band brake is mainly used. However, the former has a problem that the tape tension changes depending on the reel winding diameter, and the latter has a problem that the structure is complicated and the cost is high.

Therefore, in this device, the tape tension can be made constant regardless of the reel winding diameter, and the structure is simple and inexpensive. In order to realize this, the elasticity imparting lever means 1000 (corresponding to 723 and 724 described in FIGS. 1 to 4) is provided in the main base,
A part of the magnetic tape 706 wound around the supply-side reel 707 elastically abuts on the wound cylindrical portion, and an appropriate pressure is applied to this abutting portion. The supply-side reel 707 is a combination of a cylindrical portion around which the magnetic tape 706 is wound and a disc 707a coaxially fixed to the cylindrical portion. A part of the lever means 1000 near the contact portion is The disk 707a is brought into contact with the disk 707a at an appropriate pressure.

6 (A) to 6 (D) and 7 show an embodiment of the tape tension applying mechanism described above. In the embodiment of FIG. 6A, the base portion of the lever 1001 having elastic force is fixed to the main base 708 by a screw, and the tip portion extends in the tangential direction of the tape winding cylinder of the supply reel 707, The tape is in contact with the outer circumference of the winding cylindrical portion 706a. Felt 1002 is attached to the tip of the lever at this contact portion.
Is provided and is elastically pressed. The tape tension T is the product (μ) of the contact force (F) and the friction coefficient (μ) of the contact surface.
It is represented by F). In the embodiment shown in FIG. 6A, the contact force F is obtained by the elastic restoring force of the lever 1001 itself. FIG. 6 (B)
In this embodiment, the lever 1011 itself has no elastic force,
One end is locked to the main base 708 and the other end is the lever 1
The elastic force is given to 011. In these tension applying mechanisms, the spring constant of the lever or spring must be kept small so that F does not change much even if the reel winding diameter changes. Considering this, FIG.
As shown in (C), the spiral type lever 1012 is effective.

FIG. 6D shows another embodiment.
In this embodiment, two felts 1002 and 1003 having different directions are provided at the tip of the lever 1013.
The felt 1002 is a tape winding cylinder 706a.
And the felt 1003 is in contact with the brim-shaped disk 707a of the reel 707. Here, the tape winding tube portion 7
Assuming that the friction coefficient at 06a is (μ) and the friction coefficient at the disk 707a is (μ1), the tape tension T is (μ · F + μ1 · F).

FIG. 7A shows still another embodiment. Similar to the embodiment of FIG. 6 (D) but this example uses felt 10
In this example, three levers 02, 1003, and 1004 are provided at the tip of the lever 1001. FIG. 7B shows the contact state of the felt. The felt 1002 is in contact with the outer circumference of the tape winding cylindrical portion 706a, and the felt 1003 is in contact with the lower disk 707a of the reel 707.
4 contacts the disk 707b on the lower side of the reel 707. In this case, at the tip of the lever 1001, the felt 10
The portions supporting 03, 1004 may have curved portions S1, S2 so as to elastically press the filter against the corresponding discs. Assuming that the friction coefficients of the contact portions of the felts 1003 and 1004 are (μ1) and the friction coefficient of the tape winding tubular portion 706a is (μ), the tape tension T is (μ · F + 2μ1 · F).

FIG. 7C shows an example in which the felt 1002 is replaced with a roller 1005 in the above-mentioned embodiment. In this embodiment, since there is no felt for rubbing the magnetic tape, peeling of the magnetic powder from the magnetic tape is small and the safety of the tape is high.

Next, the feature [B] of this device will be described. In the conventional image recording / reproducing apparatus, it is necessary to provide a dew condensation sensor and a heater to prevent the tape from sticking to the cylinder. As a method of absorbing moisture from the camera, there is a method of putting a moisture absorbent into the camera, such as a vehicle-mounted rear monitoring camera. By using this method, it is possible to absorb moisture in the camera at low cost without providing a condensation sensor and a heater. However, in the case of the camera used in the distribution channel as described above, it is necessary to replace the hygroscopic material when recycling, which increases the cost.

Therefore, this device is a device which is advantageous for recycling because it can easily replace the moisture absorbing material and the acid absorbing material. To achieve this, either moisture-absorbing material or acid-absorbing material is applied to the inside of the exterior case of the camera (camera), and if the exterior case is replaced at the factory, measures against condensation can be taken automatically. It is what

FIG. 8 shows a state in which the outer case 750 around the housing 740 of the camera 700 is opened. Case 7
In the 40, an opening 741 for mechanically and electrically coupling with the reproducing device 800, and a plurality of slits 742 are formed at positions substantially opposite to the opening 741. The outer case 750 covers the whole and closes the opening 741 and the slit 742. The outer case 750 has a three-layer structure of a base and a design paper 750a, a moisture absorbent 750b applied to the inside of the paper 750a, and a waterproof film 750c coated to the outside of the paper 750a. The exterior case near the opening 741 has a single-layer structure of a waterproof film 750c.

Here, an opening 741 is formed from the reproducing apparatus 800 side.
Parts that pass through the inside and enter the inside of the camera 700 can break through the waterproof film 750c and enter. That is, in this system, the camera 700 is connected to the playback device 800.
When it is loaded into the reproducing section of No. 3, it can be loaded as it is without removing the outer case 750. At the time of this loading, in order to easily break through the waterproof film 750c in the opening 741 (see FIG. 8C), the parts that enter the inside of the camera 700 have sharp tips. This is obvious by looking at the tip shapes of the respective parts in FIGS. 2 that the positioning pin 802 has a sharp tip shape, FIG. 3 shows that the shaft 760a has a sharp tip shape, and in FIG. 4, the capstan 80 has a sharp shape.
It can be seen that the tip shape of 5 is an acute angle. This requires only the operation of loading the camera in the reproducing apparatus at the dubbing agency, and the operation of removing the outer case 750 is reduced. Also, remove the outer case 750,
The method of loading the camera on the playback device may damage other parts during the work of removing the outer case 750, and it is inconvenient because the work time is troublesome. However, the method of the present invention makes it extremely easy. It can be loaded into the playback device and ready for dubbing work.

Furthermore, in this system, the outer case 750 has the moisture absorbent 750b. Exterior case 750
Will take a used camera back to the factory and newly attach it when recycling, but at the same time, the moisture absorbent 750b will also be replaced. As a result, it is not necessary to separately provide a dew condensation sensor or a heater, which is advantageous in terms of workability and price. Not limited to the moisture absorbent 750b, it may be an acid absorbent material.

The hygroscopic material and the acid absorbing material described above are also effective for preventing the oxidation of the magnetic material of the magnetic tape. Therefore, not only the camera but also the wrapping paper or the case of the cassette has an effective effect.

Next, the feature [C] of the present invention will be described. When using the camera by recycling, tape,
It is necessary to check the mechanism, circuit, battery, etc. for defects. If it takes time and labor to perform these checks, the cost for recycling will be high.

Therefore, in this system, the inspection process can be eliminated in the recycling work, the management is convenient, and the device which is advantageous in the work cost is devised. In order to realize this, the signal processing unit of the image capturing apparatus (camera) includes means for recording not only image information on the recording medium but also information corresponding to the number of times the camera has been recycled.
This makes it possible to easily check the number of times the camera has been used and to easily manage the replacement and disposal of parts.

FIG. 9A shows an example in which information on the number of times the camera 700 has been used (the number of times of recycling) has been recorded.
The magnetic tape 706 has a leader portion 706B over a certain length from the tape start end 706A, and then has a recording portion 706C coated with a magnetic material. The upper area of the recording section 706C is used as an image recording section 706D, and the lower area is used as a control signal recording section 706E. As the control signal, pulses relating to the tape running speed and phase control are recorded. This control signal recording unit 706
At the start portion of E, there is an unused portion, and a pulse 706F indicating the number of times the camera has been used is recorded therein. In the example of the figure, the example used 4 times is shown.

FIG. 9B shows the control signal recording section 7
It is another example of using 06E. In this example, a portion actually recorded as a control signal is used as a usage number information recording unit. For example, two types of control pulses, a wide type and a narrow type, are prepared, and the number of times is represented by a combination of the wide type and the narrow type in the initial period of image recording. In the example shown in the figure, the wide type and the narrow type are pairs X1, X2, and X.
In this example, there are three as 3. The above usage count information is
It is added and recorded at the time of reproduction or recording, and this information is read at the time of inspection and used as management information for parts replacement and disposal. As a result, the inspection process can be eliminated in the recycling work, which is convenient in terms of management and advantageous in business cost.

Next, the feature [D] of the device of the present invention will be described. As described above, it is desired that the dubbing agency be convenient to handle. For example, in the case of a system that is mounted on the playback device except for the outer case, the camera may be damaged if handled by an unfamiliar person during the work. Further, in the case of the camera using the above-mentioned distribution channel, a dubbing process is necessary, but it is more suitable for the user to perform the dubbing at a high speed and immediately.

Therefore, this system is devised to be easy to handle and to obtain a dubbing of a magnetic tape that has been photographed in a short time. In order to achieve this, the playback mechanism section is made up of parts whose tip inserted into the camera has an acute angle, penetrates the exterior case of the camera, and penetrates.
Workability is improved (described above). In the reproduction side deck, for example, the first tape is reversely run in the direction from the end point to the start point for reproduction, and in the recording side deck, the second tape is reversely run in the direction from the end point to the start point for recording. I am trying. As a result, work at the dubbing agency becomes easier and safer, and dubbing can be performed at high speed.

FIG. 10 shows the appearance of a reproducing apparatus for dubbing. The camera 700 that has already taken a picture is the playback device 8
00 is mounted on the loading section. On the other hand, inside the reproducing apparatus 800, there is a re-recording deck section 830, in which a storage cassette 840 is loaded. Storage cassette 840
Is inserted from the insertion port 831. To mount the camera 700 on the playback device 800, for example, the camera 700 is inserted into the bucket 851 in the direction of arrow a1 in the figure. After that, the bucket 851 is pushed down in the direction of the arrow a2 in the figure, so that the camera 700 is set in the loading section. The figure shows a state in which the bucket 851 is lifted from the playback device 800 (before combining). Further, a state in which the camera 700 is inserted into the bucket 851 is shown at a position separated from the main body (after combination). In the coupled state, as described with reference to FIGS. 2 to 4, the camera 700 and the playback device 800 are mechanically and electrically coupled together.

FIG. 11 shows the traveling direction of the magnetic tape inside the camera 700 and the storage tape in the storage cassette during dubbing, and the reproduction and recording states. Figure 11
In the example of (A), at the time of camera reproduction, the tape is wound in the take-up reel side and is run in the reverse direction for reproduction. The storage tape is also wound in advance and is run in the opposite direction for recording. At this time, dubbing is performed by rotating the rotary heads of both the reproducing side and recording side cylinder devices in the opposite directions. When the dubbing is performed in this manner, it is possible to reduce the time as compared with the method in which the recorded tape is rewound once and the dubbing is performed while reproducing in the forward direction. In addition, in this system, reproduction can be performed using the cylinder device inside the camera.

In the example of FIG. 11B, a reproducing cylinder device and a recording cylinder device are provided inside the reproducing device.
The tape pulled out from the camera 700 is run by the playback cylinder device in the direction opposite to the recording direction for playback, and the tape is run in the reverse direction in the recording cylinder device for recording.
In other words, it is a method of recording from the end of the tape to the beginning. In any of the cylinder devices, the rotary head is a method of rotating in the forward rotation direction. The example of FIG. 11C is a method in which the rotary head of the cylinder device inside the camera is rotated in the reverse direction for reproduction, and the rotary head of the recording cylinder device is rotated in the forward direction for recording. The example of FIG. 11D is a method in which a reproducing cylinder device is provided in the reproducing device, the rotary head is rotated in the forward direction for reproduction, and the rotary head of the recording cylinder device is rotated in the reverse direction for recording. Figure 11
When the methods (C) and (D) are adopted, the field reproduction image (reproduction image for one track) is upside down on the reproduction side and the recording side. The image is vertically inverted using a memory.

FIG. 12A shows a head trace vector in the dubbing method shown in FIG. 11A. In this method, the rotary head inside the camera rotates in the direction opposite to that during recording, and traces in the opposite direction with respect to the track. In FIG. 12, V1a is a tape running vector at the time of recording, and V1b is a tape running vector at the time of reproducing, which are in the opposite direction. V2a is a head trace vector at the time of recording by the rotary head in the camera, and V2b is a head trace vector at the time of reproduction.

In FIG. 12B, the vectors V2b and V1 are
A vector V3b, which is a combination of b and b, is shown. This vector V3b corresponds to the cylinder lead angle and is a head trace vector when the recorded tape is stationary. As can be seen from this vector diagram, tracking can be obtained even if the rotary head in the camera is reversed and the tape is run in the reverse direction. On the other hand, FIG. 12C shows the tape running vector V on the storage tape inside the reproducing apparatus.
4b, a head trace vector V5b, and a track angle direction vector V6b when the tape is stationary.

FIG. 13A shows a head trace vector in the dubbing method shown in FIG. 11B. In this method, the recorded tape is pulled out from the inside of the camera by the loading mechanism and is run backward. Then, the tape pulled out from the inside of the camera is wound around the playback cylinder device provided on the playback device side to perform playback.
On the other hand, with the storage tape, recording is performed using a recording cylinder device inside the reproducing apparatus. And
This is a method of dubbing by rotating the rotary head of any cylinder device in the normal direction. In FIG. 13A, V1a is a tape running vector at the time of recording, and V1b is a tape running vector at the time of reproduction, which are in the opposite direction. V2a is a head trace vector when the rotary head in the camera is recording, and V2c is a head trace vector when the rotary head of the reproducing cylinder device provided inside the reproducing device performs reproduction. FIG. 13B shows the relationship between the vectors at the time of recording by the camera. V2a is a track recording direction vector, V1a is a tape running direction vector, and V3a.
Is a stationary track angle direction (lead angle) vector. On the other hand, FIG. 13C shows the vector at the time of reproduction. That is, in this case, since the stationary track angular direction vector V3a is combined with the reverse running direction vector V1b of the tape, the reproduction head trace is originally performed in the direction of the vector V2d. But this vector V2d
Needs to be corrected because it does not match the actual vector V2c in the track recording direction. The vector V1X is the correction vector, and this is possible by configuring the base of the rotary head with a piezoelectric element and performing dynamic tracking. FIG. 14 shows the configuration of the cylinder device portion in the dynamic tracking system. The cylinder device includes a rotary cylinder 862 that rotates integrally with the rotary shaft 860, and a fixed cylinder 861 that faces the rotary cylinder 862. The tip of the rotary head 863 is exposed in the gap between the rotary cylinder 862 and the fixed cylinder 861. And then trace the magnetic tape. The rotary head 863 includes a rotary cylinder 862 via a piezoelectric element 864.
The tracking control signal from the microprocessor 865 is applied to the piezoelectric element 864.

Returning to FIG. 13, description will be made. FIG. 13 (D)
Shows various vectors in the re-recording deck section. Even when dubbing in the re-recording deck section,
Since the storage tape is run in the reverse direction and the rotary head is normally rotated, tracking compensation of the rotary head is performed. That is, V7b is a vector indicating the traveling direction of the tape in the deck portion, V8a is a head trace direction vector when the storage tape is stationary, V9d is a head trace direction vector when tracking compensation is not performed, and V9c is tracking. It is a head trace direction vector when compensation is performed. V2X is a tracking compensation vector of the rotary head in the re-recording deck section.

In addition to the tracking by the dynamic tracking described above, there is a method as shown in FIG. That is, the head trace vector (lead angle) V10c when the tape stands still is corrected in advance, and the head is designed to trace on a regular track as the tape runs. This method can be applied to either a cylinder device inserted on the camera side or a silidan device on the re-recording deck side.

FIG. 15 shows a camera 700 and a reproducing apparatus 800.
2 shows a mechanism for pulling out the recorded tape inside the camera and loading it to the reproducing cylinder device provided in the reproducing device 800 when the two are connected. Details of this mechanism are described in detail in Japanese Patent Application No. 5-101513. A tape loading mechanism pulls out the tape 706 inside the camera 700 and can attach it to a reproducing cylinder device 835 provided inside the reproducing device 800.

The track angle correction direction by the above-mentioned dynamic tracking head and the track angle correction direction by setting the lead angle assuming the reverse traveling beforehand are respectively set on the recording deck side and the reproduction side deck section of the recorded tape. It can be arbitrarily combined and adopted.
Therefore, four kinds of dubbing forms shown in FIG. 11 are possible.

Next, the dubbing directions shown in FIGS. 11C and 11D will be described with reference to FIG. Figure 11
The example of (C) is a method in which the rotary head of the cylinder device inside the camera is rotated in the reverse direction for reproduction, and the rotary head of the recording cylinder device is rotated in the forward direction for recording. Figure 11
The example of (D) is a method in which a reproducing cylinder device is provided inside the reproducing device, the rotary head is rotated in the forward direction for reproduction, and the rotary head of the recording cylinder device is rotated in the reverse direction for recording. As a result, if the reproduced signal is directly recorded on the storage tape, the arrangement direction of the signal recorded on one track is opposite to the arrangement direction of the recorded tape. Therefore, as shown in FIG. 16, the signal for one track reproduced by the reproducing apparatus is temporarily converted into the analog-digital converter 8
At 71, it is digitized and stored in the field memory 872. Then, the fetched signals are read out in the reverse order of writing, converted into analog signals by the digital-analog converter 873, supplied to the re-recording deck section 830 side, and recorded on the tape of the storage cassette 840. As a result, when the storage tape is reproduced, the camera 700
The signal is obtained in the same direction as when the image was taken at.

Next, in the above example, the field memory 8
This is an example in which the reproduction direction of the signal for one track is converted to the reverse direction by using 72, but FIG. 17 is an explanatory diagram of an embodiment in which the field memory may not be used. The camera of this embodiment has substantially the same configuration as the camera described in FIG.
Further, when dubbing is performed by engaging with the reproducing apparatus 800, the recorded signal is dubbed on the storage tape while the tape is running in the direction opposite to that at the time of recording. At this time, the cylinder device on the reproducing device side and the cylinder device on the re-recording deck rotate in opposite directions. The feature of this embodiment resides in the scanning direction of the solid-state image sensor when the image is converted into an electric signal and recorded on the magnetic tape by the solid-state image sensor on the camera side. The direction in which pixels are scanned in a solid-state image sensor conforms to the NTSC system or the like for ordinary consumer use, and as shown in FIG. 17A, a horizontal scanning line is scanned in the Vh direction from above. Scanning is in the downward (Vv) direction. However, in this embodiment, as shown in FIG. 17B, the scanning direction of the pixels of the solid-state image sensor is the Vh ′ direction for horizontal scanning and the Vv ′ direction for vertical scanning. By doing so, it is not necessary to use the field memory as in the example of FIG. As a result, when the dubbing is performed, even if the rotation direction of the cylinder device for reproducing the tape on the camera side and the rotation direction of the cylinder device for the recording side are opposite, the tape after the dubbing is in a normal recording state. It has become.

As described above, the respective embodiments are summarized as follows. (A) In the image recording / reproducing device of the camera / reproducing device separated type, the tension regulator inside the camera is realized by a simple structure of only an elastic lever that abuts on the tape wound on the reel. This makes it possible to reduce the weight and size of the camera and reduce the cost. It is effective as a low-priced recycling camera. (B) The exterior means of the camera has a three-layer structure of a waterproof film, paper, and a hygroscopic material, and the playback device is provided with a sharp guide that breaks through the waterproof film. With this configuration, moisture and oxidation of the tape can be prevented, and at the time of dubbing work, there is no need to remove the exterior means, and handling is very convenient. (C) In addition to image information, information corresponding to the number of times of use is recorded on the recording medium of the camera to be recycled. As a result, in the inspection process of the camera, the number of times of use in the past can be known, the parts can be replaced, and it can be easily judged whether or not the limit number of uses has been reached, which is very convenient in terms of management. (D) The camera-side V
Dubbing is performed while the magnetic tape is running in the direction opposite to the normal recording / reproducing direction on both the TR and the re-recording side VTR. For this reason, tape rewinding work is unnecessary, the time required for dubbing is short, and power saving,
Tape damage during high-speed rewinding is reduced.
