Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a recording or reproducing device, and particularly to a cassette holder eject mechanism.

[Conventional technology]

Conventionally, as an eject mechanism for a cassette holder in a recording or reproducing device such as a VTR, when an fd1 person presses an eject button, the movement of the button causes
A mechanical eject mechanism operates a link mechanism to eject the cassette holder, and an electric type ejects the cassette holder by operating a switch by operating the button to operate, for example, a motor for driving the loading mechanism. There is something. Although both have their advantages and disadvantages, in recent years, due to the development of microcomputers and ease of use, there has been a tendency for electric ejection mechanisms to be used more frequently.

[Problem that the invention seeks to solve]

By the way, this electric eject mechanism uses electricity as the power source, so if the battery is exhausted, ejection cannot be performed.If the battery runs out while the cassette is still inside, There was a drawback that the cassette could not be taken out.

[Means for solving problems]

In view of the above circumstances, the present invention provides a cassette holder ejecting member, a first driving member that responds to a manual operation and drives the ejecting member, and a first driving member that is operated by the power of a motor to drive the ejecting member. This problem is solved by including a second driving member that drives the ejecting member.

[For production]

In the above, when power is available, the motor is operated and the second drive member is operated, and when power is not available, the first drive member is operated manually. The cassette holder can be injected by fully driving the eject rigid member.

FIG. 1 shows a state in which neither the battery 4 nor the AC adapter 5 is attached, and the states of each member are as shown. If you press the eject button in this state,
In conjunction with this, the button interlocking lever 13 moves in the direction opposite to arrow C (in the direction of the dashed arrow) against the biasing force of the tension coil spring 15, and the connecting rod 19 moves in the direction of arrow f using the fulcrum shaft 12j as a fulcrum. As it rotates, the eject lever 16 moves in the direction opposite to arrow d (in the direction of the broken line arrow) against the biasing force of the tension coil spring 18, and the holder lock mechanism is released by the lever 16, and the cassette holder is ejected. Ru.

In addition, in the holder lock mechanism, as shown in FIG.
The latch pin Lp of the cassette latch lever L is indented into the notch Hk of f by the biasing force of the tension coil spring S in the direction of arrow A, and latches the holder H. Therefore, when the ejector lever 16 is lowered, the latch lever L
Since the latch bin Lp is moved in the direction opposite to the arrow A, the latch bin Lp is removed from the notch Hk, and the cassette holder H is moved by the tension of the tension coil spring S of the X-shaped bar X that constitutes the elevating mechanism of the holder H. It will be ejected.

Next, according to FIGS. 5 and 6, the battery 4 or A
The electric eject operation when the C adapter 5 is attached will be described.

As shown in FIG. 5, when the battery 4 or the AC adapter 5 is inserted into the coupling part 3,
Since the outer end of is pushed into the support hole 3a, the rotating lever 9 rotates about the fixed shaft 8 in the direction of arrow g, and the fulcrum lever 12 rotates in the opposite direction of the arrow (broken line arrow direction), the fulcrum shaft 12j separates from the connecting rod 19,
It has been moved to a position where it does not interfere with the operation of the connecting rod 19.

When the eject button is pressed in this state, as shown in FIG.
0 and turns on the switch 20. by the way,
The electric eject system is constructed as shown in FIG. 8, and when the detection switch 20 is turned on, the motor control circuit 23 operates the loading motor 24 to cause the tape loading mechanism 25 to unload the tape. When the unloading is completed, the electric lever 22 moves in the direction of the arrow e, and with this movement, the cam portion 22C pushes down the upper end of the eject lever (-16) and moves the lever 16 in the direction opposite to the arrow d ( (in the direction of the dashed arrow), by the same operation as the mechanical type described above,
The cassette holder is ejected.

Note that by providing a mechanism that prohibits ejection during loading, the battery 4 or the AC adapter 5 cannot be ejected even if the battery 4 or the AC adapter 5 is removed during loading, thereby preventing trouble.

〔Effect of the invention〕
