Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnetic recording / reproducing apparatus which is effectively used in a video tape recorder (hereinafter referred to as VTR).

[0002]

2. Description of the Related Art In recent years, due to the diversification of applications and functions of VTRs, the mechanism control of VTRs has become complicated, and solutions for failures or abnormalities have become very difficult. If an abnormality occurs in the VTR mechanism in such a situation, a self-diagnosis function that semi-permanently stores the data as an abnormal state and a service person can immediately grasp the cause of the abnormality and detect the abnormality of the VTR mechanism so that it can be dealt with Is increasing.

The above-mentioned VT will be described below with reference to the drawings.
An example of R will be described. FIG. 2 is a block diagram of a conventional magnetic recording / reproducing apparatus. In FIG. 2, 2
Reference numeral 1 is a VTR mechanism unit, 22 is a mechanism control unit that controls the mechanism unit 21, and 24 is a storage unit that semi-permanently stores abnormal data of the mechanism operation. Reference numeral 25 denotes a mechanism abnormality detection unit that detects an abnormality in the mechanism operation and sends the abnormal operation to the storage unit 24 as abnormality data.
An abnormal data writing unit 6 writes abnormalities in the mechanism operation as data in the storage unit 24.

The operation of the conventional VTR constructed as above will be described below.

In FIG. 2, the mechanism control section 22 controls the mechanism section 21 of the VTR to reproduce a magnetic recording tape, fast forward it, or take out the magnetic recording tape. However, if the control from the mechanism control unit 22 is poor due to the deterioration of the mechanism unit 21 or the failure of the circuit, the mechanism unit 21 may cause an abnormality. When such an abnormality occurs, the mechanism abnormality detection unit 25 detects the state and cause at the time of occurrence of the abnormality, and sends it to the abnormal data writing unit 26 as an abnormal number. The abnormal data writing unit 26 writes the abnormal data in the storage unit 24 so that the abnormal data can be semipermanently stored even if the abnormal data is moved to the service department.

[0006]

However, in the above-mentioned configuration, a communication dedicated terminal and a communication circuit for transmitting the abnormal data from the mechanism abnormality detecting section 25 to the abnormal data writing section 26 are required, resulting in high cost. There is a problem that the peripheral circuit becomes complicated.

In view of the above problems, the present invention eliminates the need for a dedicated communication terminal or a communication circuit for transmitting abnormal data,
It is an object of the present invention to provide a magnetic recording / reproducing apparatus that can simplify peripheral devices without incurring cost.

[0008]

In order to solve the above problems, the VTR of the present invention comprises a mechanism part of the VTR and a VTR.
The mechanism control unit that can control the mechanism of, and the mechanism abnormality control unit that can detect the abnormality of the mechanism operation and write the abnormality of the mechanism operation as data in the storage device, and the abnormality data of the mechanism operation semipermanently. And a storage device capable of storing the data.

[0009]

With the above-described structure, the present invention eliminates the need for a communication-dedicated terminal or a communication circuit for transmitting abnormal data, and simplifies peripheral circuits without increasing cost.

EXAMPLE A VTR according to an example of the present invention will be described below.
This will be described with reference to the drawings.

FIG. 1 is a block diagram of a VTR in one embodiment of the present invention. In FIG. 1, 11 is a mechanism section, 12 is a mechanism control section that controls the mechanism section 11, 13 is a mechanism abnormality control section that detects abnormality of mechanism operation and outputs the abnormality of mechanism operation as data, and 14 is a mechanism abnormality control section. The storage unit semi-permanently stores the abnormal data output from 13.

The operation of the magnetic recording / reproducing apparatus of this embodiment constructed as described above will be described.

In FIG. 1, the mechanism control unit 12 controls the mechanism unit 11 of the VTR to reproduce a magnetic recording tape, fast-forward or take out the magnetic recording tape. However, if the mechanism control unit 12 does not control well due to the deterioration of the mechanism unit 11 or the failure of the circuit, the mechanism unit 11 may malfunction. Mechanism abnormality control unit 1
3 detects the state and cause at the time of occurrence of an abnormality and outputs it to the storage unit 14 as an abnormality number corresponding to the abnormal operation. Then, based on the abnormality number stored in the storage unit 14, the service department performs repairs and adjustments.

[0014]

As described above, the present invention detects the mechanism part of the VTR, the mechanism control part capable of controlling the mechanism of the VTR, and the abnormality in the mechanism operation,
To transmit abnormal data by including a mechanism abnormality control unit capable of writing an abnormality in mechanism operation as data in a storage unit and a storage unit capable of storing abnormal data in mechanism operation semipermanently. The terminal for exclusive use of communication and the circuit for communication are not required, and the peripheral circuit can be simplified without cost.
