Is turned on (S1), and if it is turned on, it is checked whether the video floppy detection switch 2 has detected loading of the video floppy (S2). If the video floppy is not loaded, the picture display segment portion 6 and the erroneous erasure prevention claw display segment portion 34 of the display 4 are blinked at the same time (S5), and the display of the numerical value display segment portion 7 is turned off (S6). , Return to <A>.

On the other hand, when the video floppy detection switch 2 detects loading of the video floppy, it is checked whether or not the erroneous erasure prevention claw detection switch 22 detects the erroneous erasure prevention claw of the video floppy (S3). Accidental erasure prevention claw detection switch 2
If 2 is on, that is, if it is an accidental erasure prevention video floppy, the accidental erasure prevention claw display segment portion 34 is displayed in a blinking manner (S10), and the flag X for storing in the control circuit 3 that the video floppy is an accidental erasure prevention video floppy. Is set (X = 1) (S11), and the process proceeds to (S8).

If the erroneous erasure prevention claw detection switch 22 is off, that is, if the video floppy is not the erasure prevention video floppy, the erasure prevention claw display segment portion 34 is turned on (S4), and the flag X is reset, that is, X = It is set to 0 (S7) and the process proceeds to (S8).

In (S8), the picture display segment unit 6 is turned on, and the number of shots is displayed in the numerical value display segment unit 7 (S9), and the process returns to <A>.

In this case, the display 4 is in the display state shown in FIG. 5, for example.

On the other hand, if the release switch 1 is turned off in (S1),

Next, the state of the flag X is checked (S14).

Here, if X = 0, that is, if the video floppy is not the erroneous erasure prevention video floppy, the erroneous erasure prevention claw display segment portion 34 is lit up and the display sequence ends (S16). Then, at the end of the waiting time in (S12), the display of the accidental erasure prevention claw display segment portion 34 is turned off.

If X = 1, that is, if the video floppy is an erroneous erasure prevention video floppy, the display sequence ends with the erroneous erasure prevention claw display segment portion 34 remaining unchanged, that is, blinking. Then, at the end of the waiting time in (S12), the display of the accidental erasure prevention claw display segment portion 34 is turned off.

In the above embodiment, when the release switch 1 is off in (S1), the display contents up to that point are displayed for a while in (S12). For example, when no video floppy is loaded, the picture display segment section is displayed. Although 6 is kept blinking, when the waiting time is set to 0 and the release switch 1 is turned off in consideration of reduction of power consumption, the display may be constantly displayed or may be turned off.

[Advantages of the Invention] As described above, according to the present invention, whether or not a recording medium is loaded is displayed on the recording medium display unit that pictorially displays the external shape of the recording medium. At first glance, it can mean the display, and since the recording medium display section blinks when the recording medium is not loaded,
It is possible to obtain an effect of being able to strongly appeal visually and surely to prompt the photographer to load the recording medium.

Further, since the presence / absence of the erroneous erasure prevention nail of the recording medium is also displayed in a pictorial form, it is possible to easily know the cause thereof in the state in which the release is not possible together with the pictorial display of the presence / absence of loading of the recording medium.

With this, not only is the presence / absence of the loading of the recording medium displayed, but also a visual display and a blinking display aiming at the visual effect, and the display is made a reliable and easy-to-recognize mode even on a small display unit. Since the blinking display is performed by turning on the release switch and is stopped by turning off the release switch, it is possible to prevent wasteful consumption of power when not in use.

In addition, when the blinking display is stopped by turning off the release switch, the blinking state is maintained for a predetermined period after the release switch is turned off, and after the holding period elapses, the display is turned on or off. Since the display does not stop immediately even if is turned off, it is easy and reliable for the operator to confirm without operating the release switch many times, and it is unnecessary to continue blinking unnecessarily.
