2. Description of the Related Art In recent years, as this kind of recording / reproducing apparatus, V
Although TRs have a very high penetration rate, especially in the case of so-called movie-type VTRs integrated with a camera unit, the needs of consumers are concentrated on reducing the size and weight of the device. It is considered an important development factor that promotes diffusion.

However, in this type of apparatus, the operation of drawing out the tape stretched in the tape cassette, winding the tape around the tape guide drum, and forming a predetermined tape path is indispensable. The basic plane size of the apparatus is largely determined by the diameter of the tape, the tape path forming means, and the size of the tape cassette.

For this reason, recently, a method of winding a tape around the tape guide drum and simultaneously bringing the tape cassette and the tape guide drum close to each other and inserting the tape guide drum into an opening in the front surface of the tape cassette is used. In many cases, miniaturization has been achieved.

[0005] Furthermore, after the operation of winding the tape around the tape guide drum is completed, an attempt is made to realize a more compact mechanism by sliding a part of the apparatus housing into a part of the space of the tape path forming means. It is shown.

Hereinafter, an example of the above-described conventional recording / reproducing apparatus will be briefly described with reference to the drawings.

Reference numeral 07 denotes an opening provided on the front surface of the tape cassette 101, and reference numeral 109 denotes a tape guide drum on which a rotary head (not shown) is mounted.

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

A first housing 122 for holding the tape cassette 101 and the like and a second housing 123 for holding the tape guide drum 109 and the like are provided at a distance A, and are surrounded by both. The tape cassette 10
This is the minimum required space for the mechanism when mounting 1 on 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 on the apparatus, the posts 110, 111, 112, 118, 1
19 and the pinch roller 120 move toward the position shown by the dashed line in the figure, respectively.
The movement is started in the directions of 12 ', 118', 119 ', and 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 dashed line, and the posts 113, 114, 115, 116,
117 begins to move in the direction of arrow 113 '

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

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

That is, the posts 113, 114, 11
The mechanism is reduced to the minimum necessary space by using a method of sliding a part of the device housing on the movement trajectory of the 5, 116. It should be noted that a specific configuration for realizing this operation is not described here because the description is complicated.

[0016]

However, in the above-described configuration, the tape 104 is moved to the tape guide drum 10.
9 to form a predetermined tape path, the tape cassette 101 and the tape guide drum 109
The space required for the operation of mounting the tape cassette 101 in the apparatus and the space for moving the second housing unit 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, space is required on the upper and lower sides of the mechanism, and it is difficult to arrange the entire mechanism. 2) When the tape cassette 101 is inserted from the direction opposite to the direction of arrow C, the user inserts the tape cassette 101 with the front surface of the tape cassette 101 on which the tape 104 is stretched, so that the tape is protected. (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 that the mechanism is complicated and it is difficult to reduce the size and weight.

In view of the above-mentioned problems, the present invention enables recording or reproduction with a minimum necessary space, but allows easy arrangement of the entire mechanism, is excellent in tape protection and operability, and has no problem in design. Another object of the present invention is to provide a recording / reproducing apparatus which does not become complicated in terms of mechanism.

[0018]

According to the present invention, there is provided a recording / reproducing apparatus comprising: a first holding section for holding a tape cassette; a second holding section for holding a tape guide drum on which a rotary head is mounted; First moving means for moving the holding section relative to the second holding section to move the tape cassette close to the tape guide drum, a rotating lid for closing the apparatus main body, and rotating the rotating lid. A second moving means for integrally moving the first and second holding portions in association with the moving operation and storing the first and second holding portions in the apparatus main body is provided.

[0019]

According to the present invention, since the tape guide drum itself can be moved in the direction in which the tape cassette approaches the tape guide drum, recording or reproduction is performed by utilizing the movement locus of the post for forming the tape path. Sometimes when the mechanism is compressed to the minimum necessary space, it can be configured with only the space on the tape cassette side, the entire mechanism can be easily arranged, and there is no problem with tape protection, ease of use, design, and equipment. Since the tape cassette and the tape guide drum are integrally stored in the apparatus main body 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, and the reliability is high. A recording / reproducing device can be realized.
