Description

[Detailed description of the invention] The present invention is designed to attach and detach magnetic recording devices (hereinafter referred to as VTRs, etc.) such as portable television cameras, especially video tape recorders or video discs, used for both broadcasting and consumer use. This relates to a color television camera that can be attached freely.

In the field of conventional broadcasting, one cameraman, one VTR person, and one person are required to take and record images during outdoor broadcasting.
Normally four people are required, one person in charge of lighting and one director, and the challenge was to reduce the number of required personnel and streamline the process. In addition, cameras and VTRs are heavy, and in order to record the captured images, they must be connected using a cable. Especially when shooting in a crowded place, this cable gets in the way and interferes with the flow of people. Many accidents have occurred, such as cables being severed due to external forces, and cable breaks account for about 80% of accidents during outdoor shooting, and the current situation is in desperate need of improvement. In order to eliminate these drawbacks, a TV camera and a VTR have been developed, but even when there is no need to record, a VTR can also be used.
need to be carried. Another drawback is that when the VTR breaks down, the entire camera becomes unusable, resulting in a lack of quick response.

When the VTR 10 is removed, the cover 17 automatically rotates 90 degrees by the force of the coil spring at the hinge 20 of the cover 17, covering the top surface of the connector jack 18 as shown in FIG. It's starting to come true.

FIG. 8A also shows a locking mechanism for attaching and detaching the VTR 10 from the camera body 4 with a single touch.

This lock mechanism is basically connected to the camera body 4.
Since the purpose is to completely fix the VTR 10, there is no problem with using ordinary cosmetic screws instead of the complicated mechanism shown in the diagram, and if necessary, fix it in multiple places instead of just one place. There is no problem even if it is a method. The lock mechanism shown in FIG. 8A is fixed at a fulcrum 21 and consists of a lock arm 22 that can rotate around the fulcrum 21 and a spring 23. It is pressed against itself, and part of its head protrudes. Further, the foot portion 25 of the lock arm 22 partially protrudes from the guide rail 8b of the camera body portion 4.
When releasing the lock and removing the VTR 10, be sure to

Since the VTR 10 is a magnetic recording/recording device, it is dangerous to ignore magnetic influences from the outside, and there are elements such as a coil assembly that utilize magnetism within the television camera body 4.
Therefore, as in the present invention, the television camera main body 4
When using VTR10 and VTR10 next to each other,
The mutual influence of each magnetism must be taken into consideration. In the present invention, the television camera main body 4 uses an aluminum plate like a normal camera, but the side plate adjacent to the camera side of the VTR 10 uses a magnetic shield plate 40 as shown in FIG. However, in the case of equipment that does not require consideration of mutual magnetic interference, such as applied auxiliary equipment described later, there is no problem with using an ordinary aluminum plate, and a magnetic shield plate may be used as necessary. When using a magnetic shield plate, from an economical point of view, a pure iron plate,
A commercially available magnetic material such as permalloy plate or miu metal may be used.

Figure 11A shows the TV camera body section 4 and the VTR1.
A plan view of the state before installing the VTR is shown.
10 can be inserted into the camera body 4 in the direction shown by arrow A. FIG. 11B is a left side view showing the state loaded in this manner. Further, FIG. 7C is a front view of the camera body section 4,
An opening 2a for attaching the lens portion 2 is visible. Further, FIG. 11C is a bottom view showing a state in which the VTR 10 is attached to the camera body 4, and there is a screw hole 30a for attaching to the tripod 30.

In the embodiment described above, the VTR 1 is installed in the camera body 4.
0 was installed, but the present invention is not limited to this embodiment and has many application examples. In other words, if you install a transmitter and attach an antenna instead of the VTR 10, you can use it as a mobile handheld device, and if you install a wireless base station near the TV camera and receive the video from the TV camera via radio waves, you can transmit it wirelessly. Therefore, there are no elements such as cables that can prevent work, so it can demonstrate great mobility in outdoor locations. In addition, if you install a wireless microphone near the subject, incorporate an audio receiving device and receiving antenna into the VTR, and shoot using a telephoto lens, you can simultaneously record the audio of extremely dangerous scenes or extremely alarming scenes. You can easily photograph and record the ecology of animals, etc., which have a strong environment.

In the above-described embodiment, the VTR 10 is described as being mounted adjacent to the right side of the television camera body, but it may also be mounted on the left or upper side of the camera. However, when attached to the tail of the camera, the overall length of the camera becomes longer, and when panning or tilting in a crowded place, there is a greater possibility of bumping into others, causing blurring and deteriorating image quality. It is designed to be installed.

According to the television camera of the present invention, it not only opens up many uses that were not available before, but also provides many advantages such as being able to enjoy high productivity, which will be listed below.

(1) Minimum of 2 photographers compared to the usual 4
It is economical and highly productive as it can be used to take pictures even with a small person.

(2) Since cables are no longer required, there are no cable breakage accidents and reliability is improved.

(3) Even when shooting in a crowded place, only one photographer can take pictures, which greatly reduces the chance of blocking the flow of people.

(4) Since the camera body and additional equipment such as a VCR are stacked on top of each other, the equipment is compact and easy to move even in a crowd.

(5) One-touch attachment/detachment makes it highly responsive and easy to replace even if the VTR breaks down.

(6) Highly adaptable to devices with other functions, not limited to VTRs, etc. In particular, the range of applications is significantly expanded by wireless transmission.

(7) Since the additional equipment is attached to the side of the TV camera case that is opposite to the cameraman's head when carried on the shoulder, the center of gravity is adjusted vertically and There is little displacement in the front-rear direction, operability is not impaired, and the operating members of additional equipment can be operated without difficulty.

(8) Since the additional equipment is inserted and removed in a direction parallel to the photographing optical axis of the television camera, the insertion and removal operations do not feel strange and are easy to operate.

(9) Since a magnetic shield plate is provided on the additional equipment, the weight of the television camera body can be reduced.
