The present invention relates to a head rotating device of a cassette player, and more particularly, by including a drive system for rotating and inverting a head installed on a deck, the head portion can be easily assembled and the deck mechanism can be made thin. To a head rotating device of a cassette player.

In general, a cassette player installed in a vehicle or portable, plays or records a note recorded on a tape, rewinds (REW), fast forwards (FF), and plays PORD PLAY, and in particular, auto reverse. As a device that satisfies the function of each mode of the AUTO RVS PLAY mode, the conventional rotating device for rotating the head to which the tape is in close contact with the driving force of the driving mechanism on the deck (not shown) is shown in FIG. A bracket head 10 having an insertion hole 10a is mounted to enable a straight reciprocating movement in the left and right directions, and the insertion hole 10a moves clockwise or counterclockwise as the bracket head 10 is moved. The rotating fan-shaped spur gear 12 is fixed by the screw 14.

In addition, one end of the torsion spring 16 is connected to the screw 14 and the other end is connected to a hinge 18 fixed on the deck, and the spur gear 12 and one side of the spur gear 12 are connected to each other. A gear head 20 that is geared is provided, and a head 22 is fixed to the gear head 20.

In the conventional head rotating apparatus configured as described above, when the running of the tape is completed or the driving is reversed from the middle, that is, when the head 20 is inverted in order to perform the auto reverse function, first, the driving force of the driving mechanism is rotated. As the bracket head 10 mounted on the deck is moved to the left direction, the spur gear 12 having one end inserted into the insertion hole 10a of the bracket head 10 is centered on the screw 14. Reversed clockwise, geared with the spur gear 12 The gearhead 20 is rotated counterclockwise to actuate the head 22.

In addition, when the driving of the tape is completed, the spur gear 12 and the gear head 20 are rotated repeatedly as the driving mechanism rotates backward and the bracket head 10 is moved to the right. To be done.

However, in the conventional head rotating apparatus configured as described above, since a number of separate intermediate members are used to rotate the head, the assembly work is cumbersome due to the increase in the number of parts, and the size of the gear head mounted on the head is kept constant. Space must be limited, and in each mode, in particular, when the auto reverse is performed, sliding occurs in the spur gears geared with the gearhead, which causes a malfunction, thereby degrading the performance of the product.

The present invention is to solve the above problems, an object of the present invention is to fix the head mounted head to the base head of the deck, to move the selection head geared to the gear head to the left, right direction By rotating and inverting the head, components such as spur gears, which are separate intermediate members for rotating the head, can be eliminated, thereby reducing material costs, thereby reducing the assembling process and workmanship. It is possible to easily adjust the diameter to secure a free space, and to provide a cassette player head rotating device that can improve the reliability of the product by preventing the malfunction because the correct position is set when performing the operation.

A feature of the present invention for achieving the above object is, in the rotary device for rotating and inverting the head in order to complete the running of the tape or to run in the middle to the reverse, the base head is vertically fixed on the deck A guide piece protruding from the upper surface of the base head, an adjustment screw tightened to the base head and a tip attached to one side of the head so as to adjust the rotation angle when the head is inserted into the bent piece, and inserted into the bent piece And a selection head fitted to the bent piece so that the gear head is fitted to the outer peripheral surface of the head and is geared with the gear head to be rotated and inverted while being moved left and right by a driving force of a driving mechanism. It is done.

Hereinafter, a preferred embodiment of a head rotating device of a cassette player according to the present invention will be described with reference to the accompanying drawings.

2 and 3 are diagrams illustrating a head rotating device of a cassette player according to the present invention, in which a base head 40 is vertically installed on a deck on which a drive system and a rotation system for driving a tape are mounted, and the base head ( 40) A bending piece 42 having a through hole is bent on an upper surface thereof, and guide pins 44 spaced apart from each other by a predetermined length are formed in the bending piece 42.

In addition, a head 48 having a tip 46 attached to one side is inserted into a through hole of the bent piece 42, and a gear head 50 is fitted to the upper outer circumferential surface of the head 48. The bracket head 40 is tightened with a plurality of adjustment screws 52 to adjust the rotation angle of the head.

In addition, a selection head 54 having a horizontal hole 54a is inserted into the guide pin 44 protruding from the bending piece 42, and the selection head 54 moves left and right by a driving force of a driving mechanism. It is geared to the gear head 50 so as to be possible.

Referring to the operation of the head rotating device of the cassette player in the present invention configured as described above in detail as follows.

First, the head 48 into which the gear head 50 is inserted is inserted into the through hole formed in the bent piece 42 of the base head 40. Then, the selection is made to the guide pin 44 protruding from the bent piece 42. The horizontal slot 54a of the head 54 is inserted. In this case, when the selection head 54 performs the auto reverse function of the cassette player in a state in which the selection head 54 is geared with the gear head 50, the selection head 54 is guide pins 44 by the forward driving force of the driving mechanism. At the same time, the gear head 50 is rotated counterclockwise to rotate the head inserted into the bent piece 42.

Here, the tip screw attached to one side of the head 48 is in contact with the adjusting screw 52 tightened to the base head 40, so that the rotation of the head 48 is limited.

When the driving of the tape is completed, the selection mechanism 54 moves to the right along the guide pin 44 while the driving mechanism reverses to regenerate the other side of the tape, thereby repeatedly repeating the sound recorded on the tape. It can be done.

As described above, according to the head rotating apparatus of the cassette player according to the present invention, components such as spur gears for rotating the head mounted on the deck are deleted, thereby reducing the material cost, and thus reducing the assembly process and workmanship. Of course, the diameter of the gear head mounted on the head can be easily adjusted to secure a free space. Since the correct position is set when the operation is performed, malfunction can be prevented and the reliability of the product can be improved.
