ャリッジ１２を移動せしめていた。FIG. 11 is a perspective view of a conventional magnetic recording device, in which the lead screw 11 engaged with the lead groove 11a in FIG.
A read bin 13, which is a drive conversion means for moving the carriage 12 carrying the recording/reproducing head 15 in the direction of arrow A, is completely fixed to the carriage 12 by adhesive or press fitting. Further, the carriage 12 is held by a pressurizing spring 17 fixed to the carriage 12 and a lead bin 13. A step motor 16 integrated with the lead screw 11
Due to zero-node rotation, the gear ridge 12 connects both ends to the frame 1.
It has a structure in which it is movable in the direction of arrow A using a guide shaft 14 fixed to the 0 as a guide via a lead spin 13 which is a rigid body. 5 and 6 are partially enlarged views of the engagement between the lead bin 13, the lead screw 11, and the pressurizing spring 17. In FIG. 5, when the carriage 12 is in a stationary state, the lead bin 13 is Although the lead screw 11 is in contact with the lead groove 11a due to the clamping force of the lead screw 17, the lead screw 11 momentarily rotates and the carriage 12
to move the lead pin 13, that is, the carriage 1.
2 instantaneously rises in the direction of arrow E, and as shown in FIG. Fig. 6 shows the moment when the carriage 12 is moved in the direction of the arrow.Since the lead screw 11 is articulated, the lead screw L-11 stops at the next moment, and the pressurized spring 17 As the condition improves, the carriage returns to the stationary state shown in FIG. 5, and at the next instant, the carriage 12 floats due to articulated rotation of the lead screw 11, creating a gap between the lead bin 13 and the lead groove 11a as shown in FIG. Then,
This behavior is repeated every time the carriage 12 moves. In the conventional carriage structure described above, the lead bin 13 moves the carriage 12 while vibrating in the direction in which the carriage 12 moves.

という大きな問題を有していた。As mentioned above, in the conventional technology, the means for converting the articulated rotation of the lead screw by the step motor, that is, the lead bin, has a rigid structure, so when the carriage moves, the carriage vibrates and generates noise, and this vibration is transmitted to the lead screw. This poses a serious problem in that it not only shortens the life of the screw and lead bin, but also generates noise, deteriorating the environment in which the magnetic recording device is used.

The figure is a perspective view of the main part of the carriage of the magnetic recording device of the present invention.
In FIG. 1, a lead plate 8 serving as a drive conversion means provides an angle θ equal to the lead angle of the lead screw 1 on the carriage 2 and engages with the lead groove 1a of the lead screw 1 to slide the carriage 2. A pressurized spring 7 having zero elasticity is fixed to the carriage 2 with a screw 9.
As in the conventional example, the lead plate 8 fixed to the carriage 2 is arranged with an appropriate direction of lead spin: L-1, and the carriage 2 on which the recording/reproducing head 5 is mounted has both ends It has a structure that allows it to slide in the direction of arrow C using a guide shaft 4 fixed to the frame IO as a guide. The lead plate 8, which has the required elasticity in the sliding direction of the carriage 2, that is, in the direction of arrow C, is connected to the step motor 6 (1) in the sliding direction of the carriage 2 when the lead screw 1 makes a steep joint rotation. However, the vibration is absorbed by its own elasticity, and the vibration propagation to the carriage 2 to which the lead plate 8 is fixed is suppressed, and the carriage 2 moves smoothly, so the sliding movement of the carriage 2 It can reduce the noise of the time.
又、リード板８が矢印Ｃ方向に弾性変位可能であること
から、キャリッジ２の浮き即ち矢印下方向の振動を極端
に抑えることができ、リード板８とリード溝１ａとが外
れる危険性は非常に少なくなる。Furthermore, since the lead plate 8 can be elastically displaced in the direction of the arrow C, floating of the carriage 2, that is, vibration in the downward direction of the arrow, can be extremely suppressed, and the risk of the lead plate 8 and the lead groove 1a coming off is extremely reduced. will decrease.

化も可能である。Figure MS2 shows a specific example of the lead plate 8, which is made up of a single leaf spring, and is provided with an engaging portion 8a for engaging the lead screw. Further, in order to securely fix it to the carriage, a screw hole 8b and a hole 8c for positioning the carriage are provided. FIG. 3 shows another specific example of the lead plate. In the lead plate 8, the carriage 2 is fixed at an angle θ equal to the lead angle of the lead screw 1, but here, the lead plate 18 itself is fixed. An angle θ equal to the lead angle is provided and the lead screw 1 is engaged. Since both are made of plate material, they can be fixed to the carriage 2 with screws 9, making it easy to assemble and reducing costs.

用する。In the embodiment described above, by disposing a lead plate on the carriage 2 that can be elastically displaced in the direction of IJJ movement of the carriage 2, the movement during sliding movement of the carriage 2 is suppressed, and smooth movement is achieved. Since dynamic movement can be obtained, noise during sliding movement of the carriage 20 is effectively reduced.

This has the effect of easily preventing the lead plate from coming off the lead screw.
