The present invention relates to a tape drooping prevention device in a V-seal, and more particularly, to a tape drooping wound around a head drum and an inclined post that is suitable for a portable V-seal. The conventional camcorder (portable V-al) traveling system deck has a take-up guide (2) which can rotate about a point on the cassette tape right reel (1) as shown in FIG. It is located, the pinch roller (Pinch Roller) 3 and the arm (4) which can rotate around the point b, is located, the Paxton motor (5) connected to the pinch roller (3) is located at the time of play.

Then, the inclined posts 7 and 8, which drag the tape and wind the tape around the head drum 6, are located at both sides of the drum 6. The tensioning arm 9 and the spring, which are tension control devices, are located on the left reel 1 'of the cassette tape.

Such a conventional camcorder (portable BC) is loaded in the order of eject, stop, and play modes, while the inclined posts 7 and 8 at both lower ends of the head drum 6 move to the top of the head drum 6, respectively. (6) Hold the tape around.

The tape wound on the cassette tape reel is wound around the take-up guide (2) and the capstan motor (5) in close contact with the pinch roller (3). The guide rollers (10, 11) of the inclined posts on both sides of the head drum and the head drum It is wound on (6).

The tape is always wound around the head drum 6 in the stop, play, forward and reverse modes.

The device for preventing the tape sagging of the prior art is composed of only the tension arm 9, and there is no device for preventing the tape sagging in particular around the head drum 6 and the inclined posts 7,8.

Accordingly, in the case of the portable V-al which has frequent external impacts, the tape wound on the head drum 6 and the inclined post guide rollers 10 and 11 may be stretched or detached due to vibration. have.

The present invention has been made to solve the above problems, will be described in detail with the following drawings.

First, FIG. 3 is a detailed structural diagram of the present invention, in which a spring-like thin metal plate 12 having a felt 13 made of wool or the like with low friction on the top of the head drum 6 is attached to both sides (left and right). 4 Attach it to the main base (14) together with the tiles.

The thin metal plate 12 attached to the main base 14 is drilled in the left side of the front protrusion of the metal plate, and in the right side so that the screw can also be inserted.

As shown in FIG. 4, the main base 14 forms a protrusion 15 on the left side to be coupled to the thin metal plate 12 and a hole on the right side to fit the screw. Referring to FIG. 2, the overall configuration of the present invention by such a configuration, the tape is wound on the head drum (6), and the inclined post guide rollers (10, 11) on both upper ends of the head drum (6) When wound, the thin metal plate 12 with the low friction felt 13 may gently press the inclined post guide rollers 10, 11 with a slight force so as not to affect tape running at all.

According to the present invention configured as described above, even if vibration occurs in the head drum 6 or the inclined post guide rollers 10 and 11 due to the external impact, the tape droops and the detachment does not occur. (6) and the inclined post guide rollers (10, 11) is not stretched or detached, replaying, tape damage can be prevented, and there is an effect that can obtain a good picture quality immediately after the play operation.

Claims (1)

In the BC-Deck having the head drum 6 and the inclined post guide rollers 10 and 11 on the upper part of the head drum 6, the felt 13 and the main base 14 are made of a material having low frictional force. It is supported and supported on both ends of the elastic member and the thin metal plate 12, and the felt 13 and the thin metal plate 12, the felt 13 and the thin metal plate 12 is inclined post guide V-type tape drooping prevention device, characterized in that configured to be pressed against the roller (10,11) with a constant force.
