It is needless to say that only the trigger switch 95 can be operated by the trigger button 96 and the power switch 94 can be separately operated by another member. The recording presence / absence detection circuit 85 is configured to detect the presence / absence of an RF (radio frequency) signal, for example, when the recording signal is an FM signal, and outputs a high-level signal when there is recording. The system controller 91 includes the detection circuit
Based on the detection output from the reference signal 85, for example, the signal on one track is sampled for the RF detection output level at the timing of the FG signal, and the R signal is detected at each FG point on the track.
When the F detection output level is equal to or higher than a predetermined value, the point is regarded as an RF point. If the RF point is equal to or more than a predetermined number on the same track, this track is regarded as recorded, and the remaining FG points are not recognized. Instead, the head is sent to the next track, and the head is checked in the same manner. Therefore, when the track is already recorded, the discriminating operation is fast. The system controller 91 includes a microcomputer or the like as a main component.
The operation will be described below with reference to the flowchart of FIG. 2 showing an example of the control procedure. FIG. 3 shows an example of a character pattern in the case where a track number is displayed on the display 92 using a seven-segment display element. In step S1, the power supply circuit 93 is turned on by the switch 94, and then the operation proceeds to the next step S2. In step S2, the system controller 91
Checks the power supply voltage of the power supply circuit 93, and if the power supply voltage has not reached the predetermined level, proceeds to step S16, performs the display "Lb" on the display IV in FIG. In step S17, the power supply circuit 93 is turned off and the process ends. On the other hand, if the power supply voltage is equal to or higher than the predetermined level in step S2, the process proceeds to step S3, where it is checked whether or not the cassette presence / absence detection switch 69 is ON, that is, whether or not there is a cassette. I do. If there is no cassette, the flow advances to step S14 to display "JJ" on the display I, and then the power is turned off in the next step S15 and the processing ends. On the other hand, if it is determined in step S3 that the cassette is present, the flow advances to step S4 to check whether or not the jacket is a recording prohibition jacket. In the case of a jacket for which recording is prohibited, the process proceeds to step S12, where the display "PP" of display III is performed. Then, in the next step S13, the power is turned off and the process ends. On the other hand, if it is determined in step S4 that the jacket is recordable, the flow advances to step S5 to perform a recording preparation operation. Here, the system controller 91 drives the head 2 by the step motor 49 and the sheet 2 by the motor 88, and moves the head to search for a recordable track. Next, in step S6, it is determined whether or not the current track position is 51 tracks. If the track is 51 tracks, the display "EJ" of the display II is performed in step S9. Then, in the next step S10, recording is prohibited, and then in step S1
Power off at 1. If it is determined in step S6 that the number of tracks has not reached 51, the process proceeds to step S7, where the track number of the head position is displayed (display V), and
In the next step S8, a recording operation is performed. Then, after moving forward by one track, the process returns to step S6. Further, in addition to the above-described embodiment, it is possible for the camera to use the display 92 to issue a warning when an unintended operation is performed. For example, when the power switch 94 is on,
When the jacket removal lever is operated or when the jacket removal lever is operated during the recording preparation, the display 92 displays a jacket non-insertion display (JJ) to warn the user. This is important from the viewpoint of the user's erroneous operation warning. In addition to this, by displaying such a form in the viewfinder, such a warning can be issued even at the time of shooting, so that it is safer. As described above, according to the present invention,
A display unit configured to detect whether a power supply capability of a power supply source of the apparatus is appropriate, a detection result of whether or not recording of an image can be recorded on the recording medium, or detection of information based on a recording amount on the recording medium; Since any of the results is displayed, there is no need to separately provide a means for displaying each result, and cost can be reduced and the display space can be used effectively. Further, according to the present invention, in a state where it is detected that the power supply capability of the power supply source of the apparatus is appropriate and that it is possible to record an image on the recording medium mounted on the apparatus. When the apparatus is in a state where an image can be recorded on the recording medium, the display means performs a display corresponding to a detection result of information based on a recording amount on the recording medium. When the power of the apparatus is turned on or the recording medium is loaded, the operator checks whether the power supply capability of the power supply of the apparatus is appropriate,
