Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a program progress instructing device for notifying performers of various instructions and remaining time when producing a broadcast program.

In the production of a TV or radio broadcast program, adjustments such as slowing down the progress of the program are made based on instructions from the program producer (director). Conventionally, this instruction has been given by the manufacturer using a hand gesture or the like while looking at a stopwatch, which has caused the problem that the instruction cannot be accurately and reliably transmitted.

Japanese Unexamined Patent Publication No. 110375/1983 discloses a device for displaying the remaining time of a program on a numerical display in this type of indicating device. However, with this device, performers cannot grasp the temporal situation of the program in an instant with a glance, and they also cannot receive instructions from the director on whether to speed up or slow down the performance, or instructions on when to start the performance (so-called cue signals). ) cannot be known at all.

To provide a program progress instructing device that can instantly know the remaining time and also clearly read instructions from a director to slow down or start an action in relation to the remaining time. It is something.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a front view of a program progression instruction device to which the present invention is applied, and FIG. 2 is a circuit diagram showing a part of the control circuit of this instruction device.

The program progress instructing device shown in FIG. 1 has a substantially rectangular parallelepiped shape, and a display section 1 is provided on the front side. Also, the side (not illuminated) is an operating section. A display window 2 is provided approximately in the center of the display section 1 to display the time until the start of the program, the elapsed time after the start, or the remaining time until the end of the program. The time or remaining time is displayed. Further, a large number of light emitting diodes are provided concentrically around the display window 2. The 60 light-emitting diodes 3 arranged in a ring on the inside display the minutes until the start of the program, the elapsed time, or the remaining time, and the 60 light-emitting diodes 4 on the outside display the seconds. conduct. Further, a light emitting diode 5 for displaying the "hour" is provided below the 60 minute position (at the top) of the diode 3 for displaying the "minute". Between the annular light emitting diodes 3 and 4, light emitting diodes 6 for markers are provided at positions that are divided into 12 equal parts (every 5 diodes) for "minutes" and "seconds" to make the time display easier to read. .

Lighting of the above-mentioned light emitting diodes 3 to 6 is performed by a time display control circuit (not shown). For example, before the program starts, for example, 15 seconds before, 45 seconds to
Fifteen light emitting diodes 4 corresponding to 60 seconds are turned on, and as time passes, they are turned off one by one, and all are turned off at the start of the program. Also, after the program starts, if you set the changeover switch on the operation panel to "decrease", for example, if it is a 15 minute program, the light emitting diodes 3 and 4 corresponding to 15 minutes will be lit and the light emitting diodes 3 and 4 will be turned on as time passes. The lights will turn off one after another and the remaining time will be displayed. Furthermore, when the changeover switch on the operating section is set to "increase", the light emitting diodes 3 and 4 are sequentially turned on as time passes, and the elapsed time is displayed. Note that in the display window 2, the remaining time or elapsed time is displayed in numbers.
Note that a conventionally known control circuit can be used as the above-mentioned time display control circuit. For example, a reference unit signal is formed by a crystal oscillator, and this reference unit signal is counted by a counter to form a time signal. However, a predetermined program circuit can display the time until the start of the program, the elapsed time after the start of the program, and the remaining time until the end of the program.

Eight light emitting diodes K ₁ to K ₈ and eight light emitting diodes L ₁ to the upper and lower parts of the display window 2 at the center of the display unit 1 are respectively provided.
_L8 is provided. The light emitting diodes L ₁ to _{L 8} at the bottom are red, and are normally not lit, and when the program is nearing the end, they are turned on at an appropriate time interval (e.g. 0.5
It lights up flashing in seconds), and all the lights stay on after the end. That is, these light emitting diodes _L1 to _L8 are used as a warning for the end of the program. The lighting of the light emitting diodes _L1 to _L8 is achieved by operating a predetermined program circuit based on the time signal obtained from the above-mentioned time display control circuit, and lighting the light emitting diodes L with a predetermined frequency signal for 15 seconds before the start of the program. ₁ to _L8 can be made to flash and turn on.

The upper light emitting diodes K ₁ ~ K ₈ are green;
These lightings are controlled by a control circuit shown in FIG. These light emitting diodes are used to give various instructions such as the start _of the program and the _speed of progress. When blinking sequentially, the performer is instructed to start the program, and when blinking sequentially from right to left (K ₈ → K ₁₎ , it is an indication to redo an act or performance during rehearsal. It is decided in advance that the command will be followed. Also, if the light emitting diodes K ₄ and K ₅ in the center are made to blink sequentially in the left and right outer directions as follows: K ₁ ←K ₂ ←K ₃ ←K ₄ ／K ₅ →K ₆ →K ₇ →K ₈ In this case, it is assumed that the instructions are given to act or play at a leisurely pace. In addition, when the light emitting diodes K ₁ and K ₈ on both the left and right sides are blinked inward in the following order: K ₁ → K ₂ → K ₃ → K ₄ /K ₅ ←K ₆ ←K ₇ ←K ₈ It is determined in advance that the person is instructed to act, perform, etc. as soon as possible. Further, it is determined in advance that when all of the light emitting diodes _K1 to _K8 are turned on, an instruction has been given to stop the performance or end the program.

Next, the blinking operation of the above-mentioned light emitting diodes K ₁ to K ₈ will be explained with reference to FIG. 2. As shown in FIG. 2, the anode terminals of the light emitting diodes _K1 to _K8 are connected to output terminals _O1 to _O8 of the ROM 8 via diodes _{D1 to} D8. In addition, the anode terminal of each of the light emitting diodes K ₁ to K ₈ is connected to the diode E ₁
~ _E8 , and are further connected to the output terminal of the monomulti 7 which operates as an instantaneous lighting circuit. In addition, the cathode terminals of the light emitting diodes _K1 to _K8 are connected to the +5V power supply line via resistors _R1 to _R8 , and these light emitting diodes
A predetermined current flows through _K1 to _K8 .

Counter 9 is installed in address terminals A ₁ to _{A 3} of ROM 8.
The output terminals O _A , O _B , O _C of the counter 9 are connected to the clock terminal CP of the counter 9, and a pulse p having a pulse period of approximately 0.5 seconds is supplied to the clock terminal CP of the counter 9. Further, a decoder consisting of diodes _F1 to _F10 is connected to the address terminals _A4 to _A6 , and push button switches _S1 to _S5 are connected to this decoder.

To explain the operation of the control circuit shown in Fig. 2, based on the counting output from the output terminals O _A to O _C of the counter 9,
Timing signals that go high and low in a predetermined order are formed in the ROM 8, and this order pattern is determined by pushbutton switches _S1 to _S5 . First, when push button switch S ₁ is pressed, address terminals A ₄ to _{A 6} of ROM 8 become “000”, and the light emitting diode is changed to K ₁ ←K ₂ ←K ₃ ←K ₄ /K ₅ →K ₆ → A timing signal for blinking in the order of K ₇ →K ₈ is obtained from the output terminals O ₁ to _{O 8} of the ROM 8. This instructs the person to act or play at a leisurely pace.
Similarly, if push button switch S ₂ is pressed,
Address terminals A ₄ to _{A 6} of ROM8 become “100” and the timing signal causes the light emitting diodes to blink in the order of K ₁ → K ₂ → K ₃ → K ₄ /K ₅ ←K ₆ ←K ₇ ←K ₈ is formed, which instructs the user to act or play quickly.

Furthermore, if push button switch S ₃ is pressed,
The address terminals A ₄ to _{A 6} of ROM8 become “010” and the timing signal causes the light emitting diodes to blink in the order of K ₁ → K ₂ → K ₃ → K ₄ → K ₅ → K ₆ → K ₇ → K _8. is formed so that the performers can be notified of the start of the program. Also, when push button switch _S4 is pressed, the address terminals _A4 to _A6 of KOM8 become "110", and the light emitting diodes are changed to _K1 ←K ₂ ←K ₃ ←K ₄ ←K ₅ ←K ₆ A timing signal is formed that flashes in the order of ←K ₇ ←K ₈ , thereby making it possible to give instructions for redoing a performance, for example, during a rehearsal. Also, when pushbutton switch _S5 is pressed, address terminals _A4 to _A6 become "001" and diode _K1
~ _K8 will all light up and you will be given instructions to stop your performance, etc. Note that if all of the light emitting diodes _K1 to _K8 are not lit, it is predetermined that an instruction to maintain the program's progress speed at the same state has been given.

When the push switch 10 connected to the trigger terminal of the monomulti 7 is pressed while the above-mentioned program progress speed is being instructed (slow, fast, same), the predetermined time constant of the monomulti 7 (approximately 0.5 (seconds), its output terminal is at ground potential. Therefore, the anode terminals of all the light emitting diodes _K1 to _K6 are brought to the ground potential via the diodes _E1 to _E8 , and they are turned on for only 0.5 seconds.
This temporary, instantaneous lighting is used to instruct the performers to start their performance, signal the insertion of sound effects, etc. That is, the push switch 10 is used as a signal for a so-called cue (a prompt for a performance).

Since the present invention has the above-described configuration, the remaining program time can be instantly known by the decrease in the number of lit light emitting elements in the row of light emitting elements, and also by the row of light emitting elements provided in the vicinity of this row of light emitting elements. Since the director's instructions to slow down the progress and start the performance can be clearly seen, the performers can optimally decide on the timing and speed of their performance based on the remaining time, the speed and speed instructions, and the signal to start the performance. can do. In addition, since only two types of display are used: a concentric circular display of remaining time and a linear lighting pattern display, performers do not misunderstand or misjudge, making it highly effective as a program progress instruction device. The structure is relatively simple and easy to read.
