The present invention relates to an audio / control head position adjusting device of a tape recorder, and more particularly, to an audio / control head of an improved tape recorder so that the x-positioning of the audio / control head is robust and easy. It relates to a position adjusting device.

In general, tape recorders such as video calsette recorder (DAT) digital audio tape (DAT) recorders and camcorders that record or play back using a cassette with a built-in tape are used to record audio information and control signals on the tape. An audio / control head is included for recording and playback, and its precise positioning is an important factor in determining the performance of the device.

1 shows such a conventional audio / control head positioning device.

First and second posts 2 and 3 having screws on the outer circumferential surface are provided on the deck 1. The first post 2 is installed to support the movable plate 4, the lower portion is provided with a torsion spring 7 for elastically biasing the support plate 4 at a predetermined angle and upward direction, the upper support plate 4 Height adjustment nut 10 for adjusting the height of the combination is combined. The second post 3 is coupled to the x-position adjusting device 11 having a conical shape with a screw on the inner circumferential surface such that the outer circumferential surface is in contact with one side of the support plate 4.

On the support plate 4, the base 5 on which the audio / control head 6 is installed is installed to be fixed by the tilt adjusting screw 8 and the azimuth adjusting screw 9 or the like.

The conventional audio / control head position adjusting device having such a structure adjusts the inclination of the front and rear angles by tightening or releasing the tilt adjusting screw 8 and adjusts the tilt angle of the azimuth adjusting screw 9 to the left and right angles. Adjust the inclination, and adjust the height by tightening or loosening the height adjustment nut (10). Then, the x-position adjusting device 11 and the torsion spring 7 are pivoted about the first post 2 to adjust the x-position of the audio / control head 6.

However, such a conventional audio / control head positioning device has a disadvantage that the position of the audio / control head x-position is not only fixed to the x-position adjusting device but also loosened by external shocks in a screwing manner. In addition, the second post and the x-position adjusting device, respectively, as well as to be assembled after processing to a predetermined shape has a disadvantage that the manufacturing is cumbersome.

An object of the present invention is to solve the above-described problems, and the audio / control of the tape recorder capable of suppressing the positional change caused by external shock as much as the x-position fixing of the audio / control head is very stable. A head position adjusting device is provided.

It is an object of the present invention to provide an audio / control head position adjusting device of a tape recorder, which has a simple structure of an x-position adjusting means, and is easy to manufacture to expect cost reduction.

A feature of the present invention for simultaneously achieving the above object is an audio / recording tape of a tape recorder including an audio / control head supporting an elastic bias in a predetermined angle direction and an x-positioning mechanism for rotating the support plate. In the control head position adjusting device, the x-position adjusting tool is inserted into the deck so as to be capable of step-down rotation, and the outer surface contacting the support plate is made of a cam curve having different radii.

This, the present invention, the forward and reverse rotation of the x-position adjusting device is rotated forward and backward along its outer surface to adjust the x-position of the audio / control head. This is because the x-position adjuster is inserted into the deck, the position fixing is very solid and stable, and the positional change of the audio / control head due to the impact from the outside is minimized. In addition, cost reduction can be expected due to simple structure and easy fabrication.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 2a, b is a cross-sectional view of the top view and the main part showing the audio / control head position adjusting apparatus according to the present invention.

On the deck 21, a post 22 having a screw on its outer circumferential surface is provided. A support plate 23 is rotatably installed on the post 22, and a torsion spring 26 for elastically biasing the support plate 23 in an upward direction and a predetermined angle direction is installed at a lower portion thereof, and a support plate 23 at an upper portion thereof. Along with fixing the height adjusting nut 29 to adjust the height is coupled. On the support plate 23, the base 24 on which the audio / control head 25 is installed is fixed by the tilt adjusting screw 27, the azimuth adjusting screw 28, and the like. At the predetermined position of the deck 21, the x-position adjusting device 30 whose outer surface on one side is in contact with one side of the support piece 23 is out sert so as to be capable of step-down rotation.

The x-position adjusting device 30 has a cam curve having an outer surface in contact with the support plate 23 having a different radius from its center of rotation, a gear 31 on the opposite side thereof, and a "+" on the upper surface thereof. &Quot; shaped adjustment groove 32. The deck 21 close to the x-position adjusting device 30 has a gear 34 engaged with the gear 31 of the X-position adjusting device 30 on the outer circumferential surface thereof, and the fastener 33 is stepped down. It is out so as to be rotatable. Here, preferably, the adjustment groove 35 of the "+" type may be formed on the upper surface of the fixture 33.

Referring to the structure of the audio / control head position adjustment device according to the present invention as follows.

Tightening or loosening the inclination adjustment screw 27 and azimuth adjustment screw 28 respectively adjusts the inclination and inclination of the audio / control head 25, and tightening or loosening the height adjustment nut 29 to the torsion spring The support plate 23 is moved up and down by the 26 to adjust the height of the audio / control head 25. Then, when the x-position adjusting device 30 is rotated forward and backward through the adjusting groove 32 using a tool such as a driver, the support plate 23 has a cam curve of the x-position adjusting device 30. The side and the torsion spring 26 are rotated forward and backward about the post 2 to adjust the x-position of the audio / control head 25. At this time, since the x-position adjusting device 30 is inserted into the deck 21, the position fixing accuracy is very high, so the audio / control head 25 is firmly fixed to the set position so that the change of position due to external shock is achieved. Suppressed as much as possible. Furthermore, it is more firmly fixed by the fasteners 33 which rotate in opposite directions through the gears 34 engaged with the gears 31 of the x-position adjusting device 30. Here, the x-position of the audio / control head 25 may be performed through the adjusting groove 35 of the fixture 33.

According to the present invention, since the x-positioning control of the audio / control head is inserted into the deck, the position fixing is very solid and stable, and the position change of the audio / control head due to external shock can be suppressed as much as possible. There is an advantage. In addition, there is an advantage that can be expected to reduce the production cost of the product by the simple structure and extremely easy manufacturing.
