Description

[Detailed description of the invention] This invention relates to a television camera device that can change the deflection angle of the image deflection and project the subject in a predetermined posture without modification, regardless of the installation conditions of the television camera. It is.

FIGS. 1a to 1c show the relationship between the mounting method and the received image for each mounting method in a conventional device. In Figure 1a, the television camera 1 is placed on a horizontal wall 5,
FIG. 1b shows the same fixed to the left side wall 6, and FIG. 1c shows the same fixed to the right side wall with the mounting legs 4. The image receiving screen 8 shows how to display the received image of the subject 3 indicated by the arrows under each mounting condition of the television camera 1.

Next, the image receiving screen depending on the mounting conditions of the television camera 1 will be explained. Assuming that the television camera is not modified and only the mounting conditions are different, when photographing the subject 3 in the same condition with the television camera 1, the television camera 1 is mounted on a horizontal wall 5 as shown in Figure 1a.
When the TV camera 1 is attached to the left side wall 6, the subject 3 is shown in the missionary position, but as shown in Figure 1b,
When attached to the camera, subject 3 faces left. Further, when the television camera 1 is attached to the right side wall 7 as shown in FIG. 1c, the subject 3 faces to the right.

As described above, in conventional camera devices, the way the subject 3 is projected changes depending on the camera installation conditions, so unless the camera is modified or the installation conditions are limited depending on the installation conditions, the image receiving screen in the missionary position will not be the same. The drawback was that it was not available.

This idea was made in order to eliminate the drawbacks of the conventional ones as mentioned above.The deflection coil inside the camera was designed to be able to rotate to the right or left, and a stopper was installed to prevent rotation overrun, depending on the mounting conditions of the camera. It is an object of the present invention to provide a camera device in which it is possible to easily obtain an image receiving screen in the missionary position regardless of the camera mounting conditions by making this adjustment possible.

An embodiment of this invention will be described below with reference to the drawings.

Figure 2a shows the interior view of the TV camera, Figure 2b
Figures 1 and 2c show detailed views of the parts used in this television camera.

In FIG. 2a, 10 is a deflection coil, and 11 is an image pickup tube, which are inserted into the deflection coil 10. Further, the deflection coil 10 is held by a coil holder 12, a coil stopper 13, and a spring 14.

Here, the coil holder 12 has a structure including a stopper A groove 16 extending in an arc shape on the front surface, stopper B grooves 17 provided at four locations on the bottom surface, and a mounting leg portion 20, as shown in FIG. 2b. The deflection coil 10 is held via a coil stopper 13 and a spring 14.

Further, the coil stopper 13 is connected to the stopper A groove 16 of the coil holder 12 as shown in FIG. 2c.
One stopper A collar 18 provided corresponding to
The structure includes four stopper B flanges 19 provided corresponding to the stopper B grooves 17.

The deflection coil 10 into which the image pickup tube 11 is inserted is attached to a coil stopper 13 having a built-in spring 1A. Deflection coil 10 and coil stopper 13
The fitting part with the deflection coil 10 is the spring 1.
4, the deflection coil 10 and the coil stopper 13 have a clearance that can be moved back and forth, but the rotation between the deflection coil 10 and the coil stopper 13 is regulated by engagement with the stopper groove and the stopper collar, as will be explained below.

The coil stopper 13 is inserted into the coil holder 12, and has a gap at the fitting portion.
The coil holder 12 is fixed to the television camera housing 15 by screws or the like.

Next, in order to rotate the deflection coil 10 to the right or left, the coil stopper 13 is pushed out toward the deflection coil 10, and the stopper A flange 18 and the stopper B flange 19 of the coil stopper 13 are connected to the stopper A groove 16 and the stopper B groove, respectively. , and manually rotate the deflection coil 10 at a predetermined angle (+ in this example).
Rotate 90° or -90°. Coil stopper 13
When the deflection coil 10 is rotated to the right or left, the stopper A collar 18 slides inside the stopper B groove 16 and stops at the end of the groove. When the deflection coil 10 is released, the elasticity of the spring 14 causes the stopper to stop at that position. Rotation is locked by the engagement between the B groove 17 and the stopper B collar 19.

In addition, although the structure in which the coil holder can be rotated to a position of ±90° and stopped at that position has been described above, the present invention is not limited to this.

As described above, according to the present invention, the deflection coil holding means is rotatably fitted and engaged with the coil holder, and the deflection coil is held at a predetermined position by the pressure of the spring. Since the structure is equipped with a coil stopper, it has the effect that normal position images can be easily obtained depending on the mounting direction of the television camera.
