2. Description of the Related Art Recently, as a recording / reproducing apparatus of this type, a V
Although TR shows an extremely high penetration rate, in the so-called movie type VTR, which is integrated with the camera unit, consumers' needs are focused on reducing the size and weight of the device. , It is said to be an important development factor for promoting diffusion.

However, in this type of apparatus, it is essential to pull out the tape stretched in the tape cassette and wind it around the tape guide drum to form a predetermined tape path. The diameter, the tape path forming means, and the three sizes of the tape cassette largely determine the basic plane dimensions of the device.

For this reason, recently, by using the technique of winding the tape around the tape guide drum, the tape cassette and the tape guide drum are brought close to each other and the tape guide drum is inserted into the opening of the front surface of the tape cassette. , The number of cases where miniaturization has been achieved is increasing.

Further, there is an attempt to realize a more compact mechanism by sliding a part of the apparatus casing into a space of a part of the tape path forming means after the operation of winding the tape around the tape guide drum is completed. It is shown.

An example of the above-mentioned conventional recording / reproducing apparatus will be briefly described below with reference to the drawings.

FIG. 16 is a plan view schematically showing a state in which the tape cassette is mounted in the apparatus, and similarly FIG. 17 is a plan view schematically showing a state in which a tape path is formed.

In FIG. 16, 101 is a tape cassette, and the tape 104 is a tape cassette 10 from a supply reel 102 in the tape cassette 101 to a take-up reel 103 via a pair of cassette posts 108, 108 '.
It is stored in a stretched state on the front of 1. Also, 1
Reference numeral 07 is an opening provided on the front surface of the tape cassette 101, and 109 is a tape guide drum on which a rotary head (not shown) is mounted.

When the tape cassette 101 is mounted in the apparatus, as shown by the solid line in the drawing, the tape path forming posts 110, 112, 113, 114, 115, 116,
117 and 119 and the capstan 121 form the opening 107.
Tape 10 inserted inside and otherwise stretched
The tape guide drum 109, the other tape path forming posts 111 and 118, and the pinch roller 120 are arranged so as to face 4 '.

A first housing portion 122 for holding the tape cassette 101 and the like and a second housing portion 123 for holding the tape guide drum 109 and the like are provided at a distance A and are surrounded by both of them. The taped part is the tape cassette 10
It becomes the space of the minimum required mechanism when attaching 1 to the device.

The operation of the recording / reproducing apparatus configured as described above will be described below.

First, when the tape cassette 101 is mounted in the apparatus, the posts 110, 111, 112, 118, 1
19 and the pinch roller 120 are directed toward the positions indicated by the alternate long and short dash line in the figure, by arrows 110 ', 111', 1
The movement starts in the direction of 12 ', 118', 119 ', 120'. At the same time, the tape guide drum 109 also starts moving in the direction of the arrow 109 ′ toward the position indicated by the alternate long and short dash line, and the posts 113, 114, 115, 116,
117 starts moving in the direction of arrow 113 ', and tape 1
04 is wound around the tape guide drum 109 to form a predetermined tape path.

FIG. 17 shows the state of formation of the tape path. First, as shown by the alternate long and short dash line in the figure, while the tape guide drum 109 approaches the tape cassette 101, the posts 113, 114, 115, 116
Moves to move the tape 104 to the tape guide drum 109
Wrap around the.

Finally, the tape guide drum 109 and the posts 113, 114, 1 are placed at the positions indicated by the solid lines.
15, 116 reach and form a predetermined tape path, and the operation ends. In addition, the second housing portion 123, which is located away from the first housing portion by the distance A, also moves by the distance B at this time, thereby realizing a more compact mechanism.

That is, the posts 113, 114, 11
The mechanism is restricted to the minimum necessary space by using a method of sliding a part of the device casing on the movement loci of 5, 116. It should be noted that the description of a specific configuration for realizing this operation is complicated and will not be repeated here.

[0016]

However, in the above-mentioned structure, the tape 104 is attached to the tape guide drum 10.
When the tape is wound around 9 to form a predetermined tape path, the tape cassette 101 and the tape guide drum 109
Since the distance between the second housing 123 and the second housing 123 is reduced and the second housing 123 is moved, a space required for mounting the tape cassette 101 in the apparatus and a space for moving the second housing 123 are required. Considering that the tape cassette 101 is configured as a movie type VTR, (1) when the tape cassette 101 is inserted from the direction of arrow C in FIG. 17, a space is required on the upper and lower sides of the mechanism, which makes it difficult to arrange the entire mechanism ( 2) When the tape cassette 101 is inserted from the direction opposite to the arrow C direction, the user must hold the front surface of the tape cassette 101 on which the tape 104 is stretched, and insert the tape cassette 101. (3) Inserting the tape cassette 101 from a direction other than the above is problematic in terms of usability and design. In addition, there is a problem in that the mechanism is complicated and it is difficult to reduce the size and weight.

In view of the above problems, the present invention makes it possible to record or reproduce in a minimum required space, but the arrangement of the entire mechanism is easy, the tape is protected and the operability is excellent, and there is no problem in design. The present invention provides a recording / reproducing device that is not mechanically complicated.

[0018]

The recording / reproducing apparatus of the present invention comprises a first holding portion for holding a tape cassette, a second holding portion for holding a tape guide drum having a rotary head mounted thereon, and the first holding portion. First moving means for moving the holding part of the device relative to the second holding part to bring the tape cassette close to the tape guide drum, a rotating lid for closing the main body of the apparatus, and a rotation of the rotating lid. Second moving means for integrally moving the first and second holding parts in conjunction with the dynamic operation and storing the first and second holding parts in the main body of the apparatus.

[0019]

According to the present invention, since the tape guide drum itself can be moved in the direction in which the tape cassette is brought close to the tape guide drum by the above-described structure, recording or reproduction is performed by using the movement path of the post for forming the tape path. At times, when compressing the mechanism to the minimum required space, it is possible to configure with only the space of the tape cassette side, the arrangement of the entire mechanism is easy, there are no problems with tape protection, usability, and design. Since the tape cassette and the tape guide drum are integrally stored in the main body of the device in conjunction with the rotating lid that closes the main body, a high load can be reliably moved by the force of the user's hand, which is highly reliable. A recording / reproducing apparatus can be realized.

The first frame 2 is held by a device body 24 having a circuit.
2 and the apparatus main body 24 are arranged so as to be separated by a distance D. The portion surrounded by the two becomes a space for a mechanism required when the tape cassette 1 is mounted in the apparatus.

The operation of the recording / reproducing apparatus configured as described above will be described below.

First, when the tape cassette 1 is mounted in the apparatus, the posts 10, 11, 12, 18, 19 and the pinch roller 20 are respectively moved toward the predetermined positions indicated by the one-dot chain line in the figure so that the arrows 10 respectively. ', 11', 12 ', 1
Start moving in the 8 ', 19', 20 'directions. At the same time, the first frame 22 starts to move in the direction of the arrow 22 ', and moves the tape guide drum 9 toward the predetermined position indicated by the alternate long and short dash line in the figure relative to the tape cassette 1. 'And the tape path forming posts 13, 14, 15, 16, 17 start moving in the direction of arrow 13', the tape 4 is wound around the tape guide drum 9, and the predetermined tape path is reached. Is formed.

FIG. 1 shows the state of formation of the tape path. First, the tape guide drum 9 relatively moves from the initial position shown by the two-dot chain line to the position shown by the one-dot chain line in the figure. While moving in the direction of 1, the posts 13, 14, 15, 16 simultaneously move and wind the tape 4 around the tape guide drum 9.

Then, when the tape guide drum 9 and the posts 13, 14, 15, 16 and 17 reach the position shown by the solid line in the figure, this time it is interlocked with the closing operation of the apparatus main body 24 by the rotating lid 60 not shown.

Further, as shown in FIG. 14, when the relative movement of the first frame 22 and the second frame 23 is completed, the release pin 76 moving together with the first frame 22 pushes the pressing lever 71 to rotate it, and The rotation blocking lever 70 is rotated through the spring 74 to release the contact between the rotation blocking pin 72 and the stopper 75, thereby enabling the relative movement between the second frame 23 and the device body 24. It enables the rotating operation of the rotating lid 60 interlocked with.

The operation of the recording / reproducing apparatus configured as described above will be described below with reference to FIGS. 6 to 14.

FIG. 6 shows a state in which the tape cassette 1 is guided by a garage mechanism (not shown) and mounted on the apparatus. As described with reference to FIG. 2, the tape path forming post is formed. 13, 14, 15, 16, 17 are located in the opening 7 (see FIG. 2) of the tape cassette 1. When the loading motor 40 is rotated in this state, the rotational driving force is transmitted to the drive gear 38 while being decelerated by the speed reduction unit 39, and the first frame 22 starts moving in the direction of the arrow 22 'via the main gear portion 22d. To do.

As a result, a relative movement occurs between the first frame 22 and the second frame 23, and the sub gear parts 22c and 2c.
The upper and lower two loading rings 29, 30 start rotating in the direction of arrow 29 'via the step gears 34, 33. However, since the rotational speeds of the two loading rings 29 and 30 differ depending on the number of teeth of the two-stage gear 33 that meshes with each other, the main boat 31 and the sub boat 32 move while being separated from each other. ..

At this time, as shown in FIG. 13, since the rotation blocking pin 72 on the rotation blocking lever 70 provided on the second frame 23 is in contact with the stopper 75 of the apparatus body 24, the second frame The relative movement between 23 and the device body 24 is prevented. Therefore, the rotating operation of the rotating lid 60 interlocked with this is also prevented, and it is impossible to rotate the rotating lid 60 during the relative movement of the first frame 22 and the second frame 23.

Next, another post 10, which is omitted in FIG.
FIG. 7 shows a loading completion state including the 12, 18, 19 and the pinch roller 20. Since the main boat 31 and the sub boat 32 rotate with a speed difference as described above, the posts 13, 14 and 15 reach the final positions described in FIG. , 17 will also reach the predetermined position. Then, by springs (not shown) provided at the rear, the springs are pressed against respective stoppers (not shown) provided on the second frame 23, and are set in a predetermined posture and stabilized. At this time, the tape 4 becomes as shown by a solid line in the figure, and a tape path is formed.

At this stage, the contact portion 2 of the first frame 22
2e contacts the end portion 23c of the second frame 23, and
The relative movement of the frame 22 and the second frame 23 is completed,
The rotation of the upper and lower two loading rings 29, 30 is also completed. In this state, post 1 is placed at the position shown by the solid line in FIG.
3, 14, 15, 16, 17 have arrived,
The predetermined tape path is completed.

Further, as shown in FIG. 14, when the relative movement between the first frame 22 and the second frame 23 is completed,
The release pin 76 on the side surface of the first frame 22 or the garage side surface (not shown) presses the pressing lever 71 provided on the side surface of the second frame 23 to rotate the rotation blocking lever 70, and the rotation blocking pin 72 and the stopper 75. Release the contact of
The second frame 23 and the apparatus main body 24 can be moved relative to each other, and the rotating lid 60 can be rotated in conjunction therewith.

Here, as shown in FIG. 10, the rotating lid 6
When 0 is rotated in the direction of the arrow 60 ′, the guide pin 63 on the arm 61 presses the side portion of the linear guide groove 64 a of the second frame 23, and the second frame 23 is integrated with the first frame 22. By moving it in the direction of the arrow 22 ', both are housed in the main body 24 of the apparatus. (See Fig. 11)
The guide pin 63 of the rotary lid 60 has a curved guide groove 6
Since it is guided by 4b, it can freely rotate without moving the second frame 23. Finally, the rotating lid 60 is locked by a lock mechanism (not shown) provided in the apparatus body 24, closing the apparatus body 24 and completely sealing the main mechanical portion from the outside. (Refer to FIG. 12) The rotation urging spring 81 stretched between the apparatus main body 24 urges the rotation lid 60 in the opening direction when it is opened and in the closing direction when it is closed. It eliminates the ambiguity of and enables simple actions by the user.

As a result, all movements with respect to the apparatus main body 24 are completed, and the entire mechanism becomes extremely compact. That is, the second frame 23 covers the rear space of the tape guide drum 9 which is required as the movement locus of the posts 13, 14, 15 after the posts 13, 14, 15 pass, and forms a tape path. The entire mechanism can be configured with the minimum required space.

In the above description, the movements of the tape path forming posts 10, 12, 18, 19 and the pinch roller 20 have not been described above, but the first frame 22 and the second frame 23 are not described. Obviously, by utilizing the relative movement of (1), a desired rotation can be easily performed by rotating a rotation lever (not shown) provided with posts.

As described above, according to the recording / reproducing apparatus of this embodiment, the first frame 22 holding the tape cassette 1 is held.
The second frame 23 for holding the tape guide drum 9.
Since the first frame 22 and the second frame 23 are integrally moved in the same direction and housed in the apparatus main body 24, the space after forming the necessary tape path can be minimized. it can. Moreover, the space required for inserting the tape cassette 1 into the garage mechanism (not shown) and mounting it in the device can be set in one direction (for example, the G direction in FIG. 8) that can be fully used, and the movie can be set. This is extremely advantageous when the entire mechanism is incorporated into a device whose primary purpose is to reduce the size and weight, such as a VTR of a type. Further, since the above-described integral movement of the first frame 22 and the second frame 23 is performed in conjunction with the rotary lid 60 that closes the apparatus body 24, a high load is reliably moved by the force of the user's hand. Therefore, the reliability of the device is increased. Furthermore, after this integral movement is completed,
Since the rotating lid 60 completes the rotating operation, the lid locking operation is independent and a reliable locking mechanism can be configured. Further, except when the first frame 22 is close to the second frame 23, the turning operation of the turning lid 60 is blocked,
The device is prevented from being damaged due to an erroneous operation by the user, and the reliability of the device is further enhanced. In addition, the rotating lid 60
When the device body 24 is completely opened, in the opening direction,

Can be provided.

The second embodiment of the present invention will be described below with reference to the drawings. FIG. 15 is a diagram showing a tape path of a recording / reproducing apparatus showing a second embodiment of the present invention.

In the figure, reference numeral 1 is a tape cassette, and the tape 4 is stretched over the front surface of the tape cassette 1 in the initial state as indicated by a chain line 4 '. Reference numeral 7 is an opening provided on the front surface of the tape cassette 1, and 9 is a tape guide drum on which a rotary head (not shown) is mounted. These configurations are similar to those of the first embodiment.

The difference from the first embodiment is that with respect to the tape path forming posts 10 to 19, two posts 13 and 18 are abolished and a post 51 is newly added. There are points. The position of the post 17 with respect to the tape 4 is moved to the outside of the tape cassette, and the relative relationship between the pinch roller 20 and the capstan 21 is also reversed with respect to the tape 4.

To form this tape path, when the tape cassette 1 is mounted in the apparatus, the posts 10, 12, 51, 14, 15, 1 for forming the tape path are formed in the opening 7.
6, 19 and the pinch roller 20 must be inserted so that the tape guide drum 9, the other posts 11, 17 and the capstan 21 are located opposite to the stretched tape 4 '.

The operation of the recording / reproducing apparatus configured as described above will be briefly described below.

First, when the tape cassette 1 is installed in the apparatus, the posts 10, 12, 51, 14, 15, 16, 1
9 and the pinch roller 20 move toward the predetermined position shown in the figure. At the same time, using the same method as in the first embodiment, the tape guide drum 9 is moved to move the tape 4 around the tape guide drum 9 by interlocking with the posts 10, 12, 51, 14, 15, 16, and 19. It is then wound around and formed into a predetermined tape path as shown in the figure.

That is, although not particularly described, by utilizing the same frame structure as that of the first embodiment, the size of the moving path of the tape path forming posts 14, 15, 16 and 17 is influenced. In addition, unlike the conventional example, it is possible to suppress the mechanism to the minimum necessary space in a state where it is not necessary to move the device housing.

The feature of this embodiment is that the capstan 21, the capstan motor 21 ', and the post 17 are not the same first frame (not shown) as the tape cassette 1 but a second frame (not shown) or device. It can be mounted on the main body 24. That is, when forming the tape path, the moving distance thereof may be reduced or may be kept fixed, and the load on the mechanism may be further reduced as compared with the first embodiment.

Also, the number of posts that move around the tape guide drum 9 is two less than in the first embodiment, and here again, the mechanism can be simplified, and the first embodiment can be used. Many advantages of the example configuration will be further enhanced.

In the first embodiment, the posts 13, 14, 15, 16 and 17 for forming the tape path are vertically separated.
The sheet was moved by utilizing the rotation of the loading rings 29, 30, but the moving method is not particularly limited,
You may comprise using a cam or a lever. Of course, the driving method is not limited to the example using the relative movement of the first frame 22 and the second frame 23.
