The present invention relates to a recording apparatus of a mini disc player, and more specifically, to simplify the structure and to reduce the production cost and to be miniaturized.

In general, a mini disc player is a device that reads and reproduces a signal recorded on the optical disc by a pickup using a cartridgeized optical disc as a recording medium or records a signal as a magnetic head on the optical disc. As an alternative to the cassette tape player used as a recording medium, the demand is increasing as the sound quality is excellent and the size is small.

In the conventional recording apparatus, as shown in FIGS. 1 to 2, the motor 2 is attached to generate the driving force on the deck base 1 in the main body, and the driving force of the motor 2 is attached to the motor. Drive gear (3) is axially coupled to receive and rotate, the deceleration gear (4) consisting of a two-gear gear is hinged to the deck base (1) to reduce the rotational force of the drive gear (3) A pair of guide pins (7) are hinged to the transmission gear (5) to transmit the rotational force, and the upper surface of the guide bracket (6) rotatably hinged to the deck base (1) is fixed to the guide bracket (7). The guide plate (8a) is formed so that the guide plate (8a) is moved to move horizontally is installed, the rack plate (9) is fixed to one side of the movable plate to receive the rotational force of the transmission gear (5).

In addition, the deck base (1) is provided with a pickup (10) to be movable left and right to irradiate light on the disk surface when the cartridgeized disk is rotated in accordance with the rotation of the tentable (not shown), A fixed plate 11 is fixed to the pickup to move together with the movement of the pickup 10, and the head arm 13 is hinged to the guide plate 6 by the torsion spring 12 on the fixed plate. And a head plate 15 having a magnetic head 14 attached thereto to record the magnetic signal to the disk at the end of the head arm, and a leaf spring 16 on the upper surface of the guide bracket 6. It is coupled to the support plate 17 to support the head plate 15 while having a rotational force toward the guide bracket (6) by, the bending plate 18 is integrally formed on one side of the support plate. The moving plate 8 has an inclined surface 19a so that the support plate 17 is forward and reversely rotated as the bending piece 18 of the support plate 17 is guided when the moving plate moves forward and backward. The protruding piece 19 is formed.

Accordingly, when the disc cartridge is inserted into the guide bracket 6 rotatably installed in the base base 1 while the cover (not shown) installed on the main body is opened, and then the cover is closed again, the disc in the disc cartridge is turnedtable ( In this state, when the user selects the reproduction mode, the signal recorded on the disc is reproduced by the reproducing apparatus, and when the recording mode is selected, the signal is recorded on the disc by the recording apparatus.

Hereinafter, the process of recording a signal on the disk will be described in more detail.

When the user selects the recording mode, the spindle motor is driven to rotate the turntable, so that the disc seated on the turntable rotates with the turntable. At this time, the pickup 10, which is movable on the deck base 1, is the disc. It irradiates light moving from the inner side to the outer side of the light, and the light hits the rotating disk surface to magnetize the disk surface.

On the other hand, when the light irradiated by the pickup 10 hits the disk surface and the disk is magnetized, the motor 2 attached to the deck base 1 reversely drives to show the drive gear 3 axially coupled to the motor. When rotated counterclockwise, this rotational force is decelerated by the reduction gear 4 and transmitted to the rack plate 9 fixed to one side of the movable plate 8 through the transmission gear 5. ) Is horizontally moved in the direction of the arrow of FIG. 1, wherein the bending piece 18 formed on one side of the support plate 17 is guided to the inclined surface 19a of the protruding piece 19 formed on the moving plate 8. The plate 17 rotates toward the guide bracket 6 around the hinge axis while receiving the restoring force of the leaf spring 16, and thus the head plate 15 supported by the support plate 17 has its own elastic force and the head arm 13 ) Rotate toward the guide bracket (6). About the axis by a hinge tosyon spring 12 force by giving turn rotates toward the guide bracket (6).

The horizontal movement of the movable plate 8 is a pair of guide pins 7 are fixed to the guide bracket 6 and the guide plate 8a is guided to the guide pins 7 to the movable plate 8. It is possible because it is formed.

In this way, when the head plate 15 is rotated toward the guide bracket 6, the magnetic head 13 attached to the end of the head plate 15 is the disc cartridge through the through hole (6a) formed on the upper surface of the guide bracket (6) In contact with the rotating disk surface therein a magnetic signal is recorded on the disk.

When the recording is performed on the disc by the above-described action, the fixing plate 11 to which the head arm 13 is hinged is fixed to the pickup 10, so that the fixing plate 11 is moved in accordance with the movement of the pickup 10. It is to be understood that the headplate 15 also moves in a state where the magnetic head 13 attached to the headplate 15 moves together and thus contacts the disk.

In addition, when a signal is written to the disc or when the stop mode is selected during recording, all operations are performed in reverse with the previously described recording mode selection. As a result, the drive of the spindle motor is stopped. It is understood that the head 13 falls on the disk in the disk cartridge.

However, in the conventional recording device of such a mini-disc player, when the recording mode is selected, the magnetic head attached to the head plate is required to be supported by the intermediate plate in order for the magnetic head attached to the head to follow the movement of the moving plate. In addition to the increasing problem, there was also a problem that it is difficult to miniaturize the device.

The present invention has been made to solve the above problems, and when the recording mode is selected, the moving force of the moving plate is transmitted to the head plate directly through the intermediate medium, so that the magnetic head attached to the head plate contacts the disk. The purpose is to reduce the manufacturing cost and to make the device compact by a simple structure.

According to an aspect of the present invention for achieving the above object, the magnetic head attached to the head plate is moved to the guide bracket as the head plate fixed to the head arm moves toward the guide bracket when the moving plate installed on the guide bracket is moved by driving the motor. In contacting the disk in the inner, including the inclined piece bent upward on one side of the movable plate installed on the guide bracket, and the guide piece guided to the inclined piece when the movable plate is moved downwardly bent formed on the head plate fixed to the head arm As the guide plate formed on the head plate is guided to the inclined piece formed on the moving plate when the moving plate is moved, the recording apparatus of the present invention provides a recording apparatus of the present invention. do.

The description will be omitted and the same reference numerals as those in the prior art will be apparent.

Hereinafter, the main configuration of the present invention will be described.

The inclined piece 20 is bent upwardly to one side of the moving plate 8 installed on the guide bracket 6, and the head plate 15 fixed to the head arm 13 has an inclined piece (when the moving plate 8 moves). The guide piece 21 is bent downwardly to be guided by 20, so that the guide piece 21 formed on the head plate 15 is formed on the moving plate 8 when the moving plate 8 moves. As guided to the head plate 15 is moved to the guard bracket 6 to bring the magnetic head 14 in contact with the disk.

In the operation of the present invention configured as described above, when the disc cartridge is inserted into the guide bracket 6 and the recording mode is selected with the disc in the disc cartridge seated on the turntable, the disc seated on the turntable rotates with the turntable. At the same time, the process until the pickup 10, which is installed in the deck base 1, to be movable, moves from the inside to the outside of the disc to irradiate light to magnetize the disc surface is the same as in the prior art.

On the other hand, when the light irradiated by the pickup 10 hits the disk surface and the disk is magnetized, the motor 2 attached to the deck base 1 is driven and driven to drive the drive gear 3 axially coupled to the motor. When the rotational direction is rotated, the rotational force is decelerated by the reduction gear 4 and transmitted to the rack plate 9 fixed to one side of the moving plate 8 through the transmission gear 5, so that the moving plate 8 is formed. Horizontal movement in the direction of the arrow of 3 degrees, in which the inclined piece 20 formed on the one side of the movable plate moves with the moving plate 8, the guide piece 21 bent downward on the head plate 15 is moved Considering that the head plate 15 is guided in contact with the inclined surface of the inclined piece 20 formed on the plate 8, the head plate 15 rotates its elastic force and the head arm 13 toward the guide bracket 6. (12) hinge by force Rotate toward the guide bracket 6 about the axis.
