Abstract

PURPOSE:To make it possible to use a motor having low reverse torque and to prevent the motor from burning at the failure of a motor control circuit by using a vibration slider crank means for a tape pulling-out means. CONSTITUTION:When a crank board 16 is rotated in the arrow (a) direction by driving a motor rotating shaft 17, the tape pulling-out members 11 is rotated around a fulcrum shaft 15 and the tape 20 is pulled out by a tape roller 13. A pull-out stopping position is set up so that the center line 26 of the crank board 16 makes a right angle with the center line 27 of the tape pulling-out member 11 and a sensor 25 is arranged. If the crank board 16 is rotated in the arrow (b) direction which is the same direction as that of the pulling-out of the tape, the tape pulling-out member 11 is restored to the original position. Said constitution makes it possible to use a motor having low reverse torque, the even if current is made to flow into the motor at the failure of the motor control circuit, the burning of the motor is not generated.

Detailed Description of the Invention (aJ Technical Field of the Invention) This invention relates to a dud BAFi cartridge type recording/playback machine, and in particular to a tape running path that draws out a tape from a tape cartridge and contacts a fixed head via a fixed tape guide. Concerning a tape pull-out mechanism for recording and playback.-1 (b) Prior art and problems Conventional tape pull-out machine S of a cartridge-type recording/playback machine
For example, as shown in Fig. 1, the arm JK tape roller 2
Directly connect the rotating shaft 4 of the tape drawer 3 with a holder attached to the rotating shaft of the motor 5 to drive the arm 1, or reduce the rotation by the motor 5 using a gear 6, 7, etc. as shown in FIG. There is a method of driving the rotary shaft 4 of the arm 1 by doing so.

In the former case, the reverse torque of the motor 5 causes the tape to run T'i lIj
If the force is greater than the + tape tension, the arm 1 will move due to the tape tension, so there is a disadvantage that the motor 5 with a large reverse torque must be used, and the latter has a gear 6.7 etc. There is a drawback that nIJ becomes longer when the tape is drawn out at 7 because of the deceleration. Also,
What is common to both is that in the unlikely event that the control circuit of the motor 5 is damaged and current continues to flow through the motor 5,
A stopper (not shown) for stopping the arm 1
In this case, the motor 5 will stop rotating, but the current will continue to flow, so there is a risk that the motor 5 will burn out.

When pulling out the tape 20 from the state shown in FIG. 3 in which the tape cartridge A is installed in the cartridge-type recording/playback machine, the tape 20 is initially straight along the cartridge surface as shown in the figure, and the tape in the tape pull-out member 11 is The roller 13 falls into the pull-out groove 21. Motor rotation shaft 17
When the crank plate 1G is rotated in the direction of the arrow a by driving, the tape pull-out member II rotates around the fulcrum shaft I5,
The tape 20 is pulled out by the tape roller 13. Further, a sensor 25 is provided to stop the tape pulling member 11 so that the pulled out tape 20 comes into contact with a fixed head 23 via a fixed guide 22 to form a tape bus for recording and reproduction. When the tape pull-out member 11 is detected by the sensor 25, the drive of the crank plate 16 is stopped, and the state shown in FIG. 4 is maintained. Note that P indicates a tape guide in the cartridge.

In addition, if the tape pull-out stop position is set so that the center line 26 of the crank plate 16 and the center line 27 of the tape pull-out member 11 are at right angles as shown in Figure @5, the tape at the tape roller I3 of the tape pull-out member 11 is The tension is T in the figure, and its component forces are T, , 'l'2, and the component force T1 is the center line 27 of the tape pull-out member 11.
Since it is on the top and is perpendicular to the crank plate 16, it does not apply any rotational force to the crank plate 16, and the component force T2 tries to apply a rotational force to the crank plate 16, but its direction is '' Since the center lines 26 of the two are in the same direction, the buckling plate 26 does not buckle! t, the tape draw-out position can be maintained.

Since the motor does not rotate in the reverse direction as described above, the motor 1lJll m'J circuit is easily configured, and even if the motor ft1lt l111 circuit is broken and current flows through the motor, the motor will continue to function. Since it can continue to rotate, the motor will not burn out.

Note that when the tape pull-out member 11 returns to the original position of the cartridge and stops, a sensor etc. (not shown)
Needless to say, the rotation of the crank plate 16 can be stopped by using 0 (f). Effects of the Invention As explained in detail above, the tape pull-out mechanism of the present invention converts the rotational motion of the motor into a swinging motion. By using the oscillating slider crank mechanism, it is possible to pull out the tape from the cassette and restore the tape to the cassette in the same rotational direction of the motor, and even in the unlikely event that current continues to flow through the motor. Since the motor can continue to rotate, burnout of the motor can be prevented, and since there is no reverse rotation of the motor, the motor control circuit can be simplified. In addition, in the oscillating slider crank mechanism, the tape is pulled out when the crank plate and arm are at right angles (by setting the position to 7, large reverse torque can be achieved without using a motor with large reverse torque as in the past) is obtained and the tape can be kept in the tape extraction position.
