DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an emergency cassette tape ejector (hereinafter, referred to as an emergency) for a video tape recorder (hereinafter, referred to as a VTR).

[0002]

2. Description of the Related Art In recent years, an emergency eject device has been widely used for a mechanism section of a VTR, and various attempts have been made.

[0003] Conventionally, there is an emergency ejection performed when an abnormality is detected when the power is turned on or an emergency ejection that is manually performed while looking inside the VTR in an emergency, but there is no emergency ejection that is performed externally when the power is turned off due to a power failure or the like.

[0004]

In such a conventional configuration, in many cases, the cassette tape cannot be removed in an emergency (such as a power failure). Further, even if it is possible, it is very time-consuming and troublesome to remove the exterior portion and manually perform the operation to view the inside of the VTR deck.

An object of the present invention is to solve the above-mentioned problems, and an object of the present invention is to provide an emergency eject apparatus which can take up and take out a tape from the outside of a VTR deck without taking much time.

[0006]

According to the present invention, there is provided an emergency cassette tape unloading apparatus, comprising: a loading motor for transmitting power to a tape loading mechanism; an unloading completion detection sensor provided on the tape loading mechanism; A video having a reel power transmitting means for transmitting power to a rotating supply side reel or a winding side reel, and a control circuit connected to the loading motor, the unloading completion detection sensor and the reel power transmitting means by a first wiring. A tape recorder having a connector connected to the loading motor, the loading completion detection sensor, and the reel power transmission means by a second wiring, wherein the connector is provided at a position connectable from outside the video tape recorder; Tape recorder and connector An external connector connectable to, and a external device having a power supply for supplying a voltage to the external control circuit and the external control circuit.

[0007]

According to the present invention, in the case of an emergency VTR,
By connecting the connector of the external device to the connector provided on the part facing the outside of the deck, the tape can be easily and quickly taken out.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An emergency cassette tape take-out apparatus according to one embodiment of the present invention will be described with reference to FIGS. 1 and 2, 1 is a loading motor for transmitting power to a tape loading mechanism, 2 is an unloading completion detection sensor, 3 is a magnetic tape,
4 is a supply reel for winding the magnetic tape 3, 5 is a take-up reel, 6 is a reel motor for transmitting power to the take-up reel 5, 7 is a set-up motor for transmitting power to a set-down mechanism, 8, a control circuit connected to the loading motor 1, the loading completion detection sensor 2, the reel motor 6, and the set-up motor 7;
Reference numeral 9 denotes a VTR including the above 1 to 8, and reference numeral 10 denotes a connector provided on the front surface of the VTR 9 and connected to the 1, 2, 6, and 7.

Reference numeral 11 denotes a connector connectable to the connector 10, reference numeral 12 denotes a control circuit for sending or receiving an unloading operation signal, an unloading detection signal, a tape winding operation signal, and a set-up operation signal to the connector 11, and 13 denotes a connector. A power supply connected to the control circuit,
Reference numeral 4 denotes an external device including the devices 11 to 13.

In the above configuration, when the cassette tape is to be taken out in an emergency (power failure, etc.), the connector 11 of the external device 14 is connected to the connector 10 on the front of the VTR deck 9, and the driving voltage in the unloading direction is applied to the loading motor 1. To transmit power to the tape loading mechanism and supply a drive voltage to the reel motor 6,
Perform the unloading operation while winding the tape. When the completion of the unloading operation is detected by the unloading completion detection sensor 2, the supply of the driving voltage to the loading motor 1 is stopped, and the unloading operation is completed. Next, a drive voltage is supplied to the power set-up motor 7 while the tape is being wound, and power is transmitted to the power set-up mechanism to take out the cassette.

According to the emergency eject device of the above embodiment, a loading motor for transmitting power to the tape loading mechanism, an unloading completion detection sensor, and a supply-side reel of a parallel two-reel type for winding a magnetic tape. And a take-up reel, a power transmission means for transmitting power to the take-up reel, and a power set-up motor for transmitting power to a power-down mechanism. The power transmission means for transmitting power to the side reel and the wiring to the power setup motor are installed together, one is connected to the drive circuit inside the VTR, the other is directly connected to the connector on the front of the VTR, and the unloading operation signal is sent to that connector. Unloading detection signal and tape winding operation signal It can be taken out safely and quickly cassette tape in the VTR internal or not open the VTR in an emergency such as a power failure by connecting an external device having a circuit and a power source for sending a setup operation signal. Ma
In addition, the external device 14 is directly connected to the external device 14 without passing through the control circuit 8.
Loading motor and unloading completion detection sensor
Power transmission means and cassette for transmitting power to the take-up reel
Drive circuit inside the VTR to connect to the motor
Even in an emergency due to a failure of the control circuit 8 including the
Safely and quickly take out the cassette tape in the section
it can.

Means for transmitting power to the take-up reel includes not only a reel motor but also a means for swinging a brake in contact with the reel.

When the tape is wound on the supply reel side during unloading, power may be transmitted to the supply reel 4.

When the loading motor drives the power set-down mechanism, the power set-up motor 7 can be omitted.

[0015]

According to the emergency cassette tape ejecting apparatus of the present invention, wiring for emergency ejection inside the VTR is provided, and even if an emergency such as a power failure occurs while the VTR is in use by having an external device , Emergency such as control circuit failure
Even if the error occurs, if an external device is connected, the cassette tape inside the VTR can be quickly taken out without opening the VTR, and tape damage can be prevented.
