DESCRIPTION

Numeration display and retransmission token for multi-camera film and television system.

Technology Sector

In the viewfinders of cameras used in multi-camera systems, a plastic number is used to show what position that camera occupies in question in the total set, facilitating tasks for the presenter or actor of a program. This number is currently plastic and is placed by means of two pins in the viewfinder. When the camera numbering is changed due to production circumstances, this number often breaks the pins, and if a camera is used in more than one television program this often happens.

This model solves this problem by not having to replace it when the numbering changes. It also indicates if this camera is being punctured and significantly improves the visibility of the mentioned number

Background of the invention

There is the aforementioned device for representing the plastic number in the viewfinder, as well as a warning light that indicates if this camera is broadcasting.

Explanation of the invention

This display is composed of a system of light representation electronically that represents the numbers from 0 to 9. To select the number that this camera will represent in the camera chain it is proposed that an operator presses a button, which increases the value of the number in a unit, stopping when it reaches the corresponding number to be represented. This display has two states, the first one of low luminosity, when the camera is not retransmitting and another state of high luminosity when it is retransmitting, doing the functions of relay witness. In this way the minimum illumination in the low light state is used for the representation of the number in a readable way. This low light state avoids multiple unwanted reflections in the scene to be transmitted.

Brief description of the drawings

Figures 1 and 2 respectively represent the front view, and the proposed electronic scheme for display assembly.

Figure 3 represents the front view of the display connector.

In Figure 1 you can see the button (1), which changes the numbering, a switch (2), the rubber bands (3) for placement, the display (4) representing the desired number, and the box ( 5) which houses the assembly.

The proposed electronic assembly is shown in Figure 2. Following the scheme we find a diode (1) that protects polarity faults, the ignition switch (2) the resistance (3) anti-rebound, the button (4), connected to the clock input of the counter

(5) of displays. A 7 segment display (6), the limiting resistance (7), whose value is responsible for the low light state, a transistor (8), which is the one that, due to the state of its base, changes from cut to saturation, changing from state, a limiting resistance (9) whose value is significantly lower than the resistance (7), an inverter (10) 5 that reverses the signal that arrives at the relay signal terminal.

Figure 3 shows the connector and how the terminals should be connected, so we see the ground terminal (1), tally (2), an unconnected terminal (3), and positive (4). It is a 4 pin male connector.

Preferred Embodiment of the Invention

A preferred embodiment of this apparatus is proposed, using a 7-segment common display (Fig. 1,4) of 5 centimeters wide, red, mounted on a black box 15 (fig. 1) with elastic rubber fasteners ( fig 1, 3).

An electronic circuit is proposed based on a 4026 display counter (fig 2, 5) with limiting resistance values (fig 2, 7) of 3300 ohms, and limiting resistance (Fig 2, 9) of 220 ohms, connector (Fig 1, 7) Hirose 4 male pins.

This circuit when connected to the 12-volt output of a camera or an external power supply, represents the number on the display (6) changing from a minimum brightness state to maximum brightness when receiving a signal at its relay signal terminal.

The rubbers (Fig 1,3) facilitate their placement in the viewfinder and even on the tripod.

It is also proposed the integration in the camera viewfinder.
