2. Description of the Related Art Generally, a video tape recorder (VTR) is provided with various sensors such as a cassette mounting sensor and a cassette nail breakage sensor, and the system controller operates when the VTR cannot record. Then, even if the record button is pressed, the record mode is not entered. When such a situation occurs, the operator of the VTR can estimate the cause of the situation and reset it so that the correct operation is performed. However, an operator who is unfamiliar with the operation of the VTR can press the VTR when the recording button is pressed.
Often I don't know why doesn't work.

In many cases, the VTR performs reserved recording in conjunction with a timer. Therefore, in preparation for a recording error during unmanned operation, various wrong settings are checked when setting the reserved time (for example, the reserved time zones are overlapping). , Checking that the tape length is insufficient for the recording time width) is performed in advance. Also in this case, when an error display appears on the timer display unit, an operator unfamiliar with the timer operation may not understand what the error display means. In particular, timers used in VTRs, etc., start time setting button, end time setting button, time input button, day input button, memory selection button for reserving multiple programs, erroneous correction button, reservation content confirmation button, etc. It is configured to make a program recording reservation while watching the display (time and day) on a liquid crystal display or a fluorescent display tube. When making a timer reservation, in addition to the above buttons, you can also operate channel buttons. Join,
Therefore, the reservation operation is extremely complicated and erroneous.

By providing a monitor lamp corresponding to the cause and reason of the operation of recording prohibition or cancellation by the various sensors in the VTR as described above or the reason and situation of the timer erroneous setting, these causes and situations can be read. It is possible to do so, but if the number of displays increases, the device becomes complicated and it is often difficult to understand. The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to resist a device which is easy to use and which minimizes a gap between a machine and a human without relying only on display.
