DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display device, for example, a magnetic recording / reproducing device (hereinafter, referred to as a VTR) having a display device, which can provide a new method for presenting a warning message. .

[0002]

2. Description of the Related Art Conventionally, when an abnormality occurs in a VTR main body, a method is used in which a warning lamp is turned on or the content of the abnormality is displayed in an abbreviated form or an arbitrary number on a display device at the time of the abnormality. Or, a VTR having a dedicated button for confirming the contents of a warning is generally known.

[0003]

If any abnormality occurs in the main body during the operation of the VTR, the operation manual must be consulted each time to know the details of the warning by the conventional method, and the occurrence of the error has occurred. When a device error is a warning that is not directly related to the current operation or a warning that has been generated intentionally, a forced warning display significantly interferes with the original operation and results in a reduction in work efficiency. I was

[0004] Therefore, an object of the present invention is to solve the above-mentioned problems, and for example, it is possible to confirm the contents of an abnormality that has occurred in the main body by the operator without impairing the operational feeling during the operation of the main body, and to take appropriate measures. A display device is provided.

[0005]

In order to achieve the above object, the present invention is a display device capable of displaying various information from a main body, wherein when an abnormality occurs in the main body, information indicating the abnormality is displayed in another form. Abnormality display means for displaying the information outside the display area;
An abnormality content display means for displaying the content of the abnormality after the abnormality information is displayed.

[0006]

According to the present invention, when an abnormality occurs in the main body, the fact is indicated without affecting other display areas, and then the details of the abnormality are indicated.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of the present invention will be described in detail with reference to FIGS.

FIG. 1 is a block diagram of a VTR according to the present invention. In FIG. 1, reference numeral 1 denotes a microcomputer (microcomputer) group for controlling the mechanism of the VTR. Among them, a system control unit 1A controls a flow of data among a mechanical control unit 1B, a video control unit 1C, and a servo control unit 1D. Also 2A
Denotes a panel control unit, which is a switch group 2 serving as an input device.
A microcomputer which receives an input from B and controls a man-machine interface such as control of the display device 2C. The microcomputers described above are electrically connected so that information can be input and output to and from each other. FIG. 3 shows the display contents of the display device 2C, reference numeral 30 denotes a display area for normal operation display and alarm contents, and reference numeral 31 denotes an alarm display area.

FIG. 2 is a flowchart showing a process from a normal display to an alarm display. In the normal flow, a normal operation display is performed on the display device 2C in S1 (the display content is 3-3 in FIG. 3).
1) In S2, it is determined whether there is an alarm. When an abnormality occurs in the main body, the system control unit 1A sends the panel control unit 2A.
Is interrupted by an alarm signal. When an alarm is detected in S2, a warning occurrence notification is displayed on the display device 2C in S3 (the display content is indicated by 31 in 3-2 in FIG. 3 and the alarm blinks), and one of the function buttons of the switch group 2B is displayed. One for the transition to the alarm mode. In this state, S4
As described above, the operation enters a loop waiting for key input. However, if the button input is for an operation unrelated to the generated alarm, the operation can be continued without any problem. When the alarm mode shift switch of the switch group 2B is input, the mode shifts to the alarm mode in S5, and details of the alarm are displayed on the display device 2C (the display contents are 3-3 in FIG. 3). Here, the operator confirms the contents and operates the confirmed warning display by button operation (S
6) You can cancel by doing (S7),
Alternatively, if the warning display is not stopped, the operation can be continued while the warning occurrence notification is displayed (S7 → S3).

[0010]

As described above, according to the present invention, even if any abnormality occurs in the main body, the contents of the abnormality (warning) can be known by the operator's own selection without impairing the original operability. Can take appropriate measures.
