Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnetic recording / reproducing system.

[0002]

2. Description of the Related Art Conventionally, a magnetic recording / reproducing apparatus, for example, V
The TR has a magnetic tape packaged and an automatic tape loading mechanism in order to protect the magnetic tape as a magnetic recording medium and facilitate the tape loading.

A conventional tape loading mechanism is shown in FIG. The cassette comprises a cassette half 101, a corresponding cassette half, and a rotary lid, and a reel has a cassette reel 103 as a supply reel and a take-up reel.

When the cassette is inserted into the VTR, the operation automatically opens the rotary lid. At this time, the skates 114, the pinch rollers 106, etc., which are at the positions indicated by the alternate long and short dash line in the figure, move along the rails 116, the skates 115 move along the other rails, and the magnetic tape 102 skates accordingly. 114 Drum outlet side inclined post 1
12 and the tape guide 110, the inclined post 113 on the drum entrance side of the skate 115, and the tape guide 110 pull out from the cassette. And the skates 114,
When the movements of 115, the guide roller 111, the pinch roller 106, etc. are completed, the loading is completed, and the tape path from the supply reel to the take-up reel is formed. Also,
The tension arm 117 is rotated counterclockwise in the figure, and tension is applied to the magnetic tape 102 by the guide roller 111.

[0005]

However, in the above-mentioned conventional example, the loading mechanism is complicated and the number of parts is large, so that there is a problem that the cost becomes high.

An object of the present invention is to solve the above problems and to provide a magnetic recording / reproducing system capable of reducing the number of parts for loading a magnetic tape.

[0007]

In order to achieve such an object, the present invention winds a tape-shaped magnetic recording medium between a supply reel and a take-up reel around a guide pair so as to face a front opening surface. A magnetic recording medium container having a drum inlet side inclined post and a drum outlet side inclined post between the pair of guides, a rotary head drum having a lead, and the drum inlet side inclined post and the drum on the rotary head drum. Loading means for holding the tape-shaped magnetic recording medium in a pressed state between the outlet-side inclined posts and movement of the magnetic recording medium container loaded by the loading means in the width direction of the tape-shaped magnetic recording medium. And a restricting means for restricting in cooperation with the lead provided in the.

[0008]

According to the present invention, the magnetic recording medium container is loaded by the loading means while the tape-shaped magnetic recording medium between the inclined post on the drum inlet side and the inclined post on the drum outlet side provided on the magnetic recording medium container is pressed against the rotary head drum. The movement of the held and loaded magnetic recording medium container in the width direction of the tape-shaped magnetic recording medium is regulated in cooperation with the regulating means and the lead provided on the rotary head drum.

[0009]

Embodiments of the present invention will now be described in detail with reference to the drawings.

FIG. 1 shows an embodiment of the present invention.

FIG. 2 is a plan view of the magnetic recording / reproducing system shown in FIG. 1. The magnetic recording / reproducing system comprises a magnetic recording / reproducing device and a magnetic recording medium container.

In the magnetic recording medium container, two reels (supply reel and take-up reel) 3 are arranged in parallel in a cassette half 1, pinch rollers 6 are respectively arranged at front corners, and two pinch rollers 6 are provided. A drum outlet side inclined post 4 and a drum inlet side inclined post 5 are arranged in between.

The magnetic recording / reproducing apparatus has a rotary head drum 8. The rotary head drum 8 has a rotating middle drum and a fixed upper and lower drum. A head is attached to the middle drum and a lead is attached to the lower drum. Is provided. U-shaped post bases 9 are attached to both sides of the rotary head drum 8 so that their tip portions are respectively located, and upper regulation guide rollers 10 for regulating the upward movement of the magnetic tape 2 are arranged at their tip portions, respectively. A capstan 7 for sending the magnetic tape 2 in cooperation with one of the pinch rollers 6 is arranged near one of the upper regulation guide rollers 10.

In the state where the cassette half 1 is moved in the direction A in FIG. 1 and loaded in the magnetic recording / reproducing apparatus, the magnetic tape 2 between the drum entrance side inclined post 5 and the drum exit side inclined post 4 is a rotary head drum. 8 is wound around the rotary head drum 8 and is tense, and the drum inlet side inclined post 5 and the pinch roller 6
The magnetic tape 2 between the magnetic tape 2 and the magnetic tape 2 between the drum outlet side inclined post 4 and the pinch roller 6 are pressed against the upper regulation guide post 10, respectively.
Are pressed against the magnetic tape 2 on the pinch roller 6.

Therefore, the running magnetic tape 1 has its upper end regulated by the regulation guide roller 10 and its lower end regulated by the lead of the rotary drum 8. Therefore, the tape 11 comes to follow the lead of the rotating drum 8 accurately,
A tape path is formed.

In this embodiment, an example of the rotary head drum 8 having a rotating middle drum and fixed upper and lower drums, a head attached to the middle drum, and leads provided on the lower drum has been described. Instead of the head drum 8, a rotary head drum having a rotating upper drum and a fixed lower drum, a head attached to the upper drum, and a lead provided on the lower drum may be used. In this case, the effects are essentially the same. The cassette half 1 can be used even if it is turned upside down.

Another Embodiment FIG. 3 shows another embodiment of the present invention.

Compared with one embodiment, this embodiment is different in the direction of movement regulation of the magnetic tape 2 by the lead and the regulation post. That is, in one embodiment, the lower end of the magnetic tape is regulated by the lead and the upper end is regulated by the upper regulation post 10, but in the present embodiment, the lower end of the magnetic tape is regulated by the lower regulation post 18 and the upper end is regulated by the upper drum. It was regulated by the lead provided in.

The magnetic tape 2 is pushed by the lower regulating post 18 at the entrance of the rotary head drum 8 in the direction a shown in FIG.
Since it is pushed in the b direction by the reed and is pushed in the a direction by the lower regulation post 18 at the exit of the rotary head drum 8, it is possible to travel along the reed on the rotary head drum 8 with high precision.

[0020]

As described above, according to the present invention,
Since it is configured as described above, there is an effect that the loading mechanism can be simplified.
