FIG. 2 shows a block diagram of a circuit for blinking and changing the brightness of the tally lamp 14 in the apparatus shown in FIG.

The shooting mode input unit 26a corresponds to any of the operation buttons 26 in FIG. 1, and the operator inputs a shooting mode instruction. The brightness of the tally lamp 14 can be selected from, for example, one of two levels as described later, and the brightness of the tally lamp 14 is selected according to the shooting mode input from the shooting mode input unit 26a by the operator. .

The control unit 30 receives a signal indicating the shooting mode sent from the shooting mode input unit 26a and a VTR sent from the recording / playback unit 32.
The tally lamp drive unit 36 according to the signal indicating the operating state of
Control signal is output to. The power supply 34 is a power supply that supplies electric power for turning on the tally lamp 14.

The tally lamp drive unit 36 controls the supply to the tally lamp 14 by adjusting the voltage supplied from the power source 34 according to the control signal sent from the control unit 30. As a result, the tally lamp 14 blinks and the brightness is changed.

FIG. 3 shows a concrete example of the tally lamp drive unit 36 of FIG.

The positive terminal of the light emitting diode 14a used as the tally lamp 14 is connected to the power supply Vcc, and the negative terminal of the light emitting diode 14a is connected to the collector of the transistor Q1 via the resistor R1.
Further, they are respectively connected to the collector of the transistor Q2 via the resistor R2. The values of resistors R1 and R2 are, for example, R1
It is set so that = 2R2.

The base of the transistor Q1 is connected to the control unit 30 via the resistor R11 and the signal line 102, and a control signal is sent from the control unit 30 through the signal line 102 when the VTR is performing recording by normal operation. The base of the transistor Q2 is a resistor R2.
1. Connected to the control unit 30 via the signal line 104, a control signal is sent from the control unit 30 through the signal line 104 while the VTR is performing recording by remote control operation. Transistor Q1
The emitters of Q2 and Q2 are respectively connected to the earth.

The operation of blinking the tally lamp 14 and changing the brightness will be described with reference to FIGS. 2 and 3.

Before shooting, the operator gives an instruction whether normal shooting or shooting with remote control operation
Input from 26a. The shooting mode instruction input from the shooting mode input unit 26a is sent to the control unit 30. When the operator presses the record button of the operation buttons 26 to start shooting and recording, shooting of the subject and recording of the captured video signal on the magnetic tape are performed. As a result, the recording / reproducing unit 32 sends a control signal to the control unit 30 to the effect that shooting is in progress.

When the control section 30 receives a signal indicating that the shooting is in progress, the control section 30 outputs a control signal to the signal line 102 or 104 in FIG. 3 according to the shooting mode input from the shooting mode input section 26a. If the shooting mode is normal shooting, the signal line
A control signal is input from 102 to the base of the transistor Q1. That is, a positive voltage is applied to the base of the transistor Q1. Therefore, from the power supply Vcc to the light emitting diode 14
A current flows through a, the resistor R1, and the transistor Q1 to turn on the light emitting diode 14a. Since the resistance R1 has a large value, the current flowing through the light emitting diode 14a at this time is small and the brightness of the light emitting diode 14a is small.

On the other hand, when the shooting mode is shooting by remote control, a control signal is input from the signal line 104 to the base of the transistor Q2. That is, a positive voltage is applied to the base of the transistor Q2. Therefore, a current flows from the power supply Vcc through the light emitting diode 14a, the resistor R2, and the transistor Q2, and the light emitting diode 14a lights up. Since the resistor R2 has a small value, the current flowing through the light emitting diode 14a at this time is large and the brightness of the light emitting diode 14a is high.

It is changed so that it becomes larger at the time of shooting. Therefore, the brightness of the tally lamp 14 increases when the operator operates the remote control away from the device, so that the operator can easily visually recognize the lighting of the tally lamp 14 even when the remote control is operated.

By changing the values of the resistors R1 and R2 in FIG. 3, the difference in brightness of the tally lamp 14 depending on the photographing mode can be changed to a value other than the above ratio.

Further, according to the shooting mode input from the shooting mode input unit 26a, in addition to or instead of increasing the brightness when operating the remote control, the operator inputs an instruction of the brightness of the tally lamp. Good. For example, when shooting outdoors on a sunny day, it is difficult to check the lighting of the tally lamp, so the operator inputs an instruction to increase the brightness,
The control circuit similar to that described above may be used to increase the brightness of the tally lamp. In this way, the brightness of the tally lamp may be changed regardless of the shooting mode.

In the above embodiment, a power supply for supplying a constant voltage is provided, the value of the current flowing through the light emitting diode 14a is controlled by changing the resistance value, and the brightness of the light emitting diode 14a is changed. The brightness of the light emitting diode 14a may be changed by providing it and selecting it. Further, instead of changing the brightness of the tally lamp, a tally lamp with a plurality of different colors is provided, and the light generated from the tally lamp is selected by selecting the tally lamp according to the lighting condition of the place where the shooting is performed. The color of may be changed.
