Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a battery coupler, and particularly to a camera-type VT.
Regarding the battery coupler used for R.

[Conventional technology]

■With the spread of camera-integrated VTRs, it has become necessary to use a battery coupler to overcome the lack of brightness and ensure that the photographer can obtain satisfactory image quality even when shooting indoors or outdoors at dusk. It is becoming common.

Additionally, an increasing number of photographers are using high-performance microphones to improve not only image quality but also sound quality.

The battery coupler and high-performance microphone are attached to the accessory shoe on the camera body.

■Furthermore, camera-integrated VTRs, electronic still cameras, etc. generally consume relatively large amounts of power. For this reason, a battery that supplies a relatively large amount of power is required, and from the viewpoint of running costs, a dedicated rechargeable battery (hereinafter referred to as "battery") is required.
is often used. After this battery is used (discharged) for a predetermined period of time, it is charged and continues to be used.

To charge the battery, first connect the battery charger plug to A.
Connect it electrically to the C outlet, then remove the battery from the camera body and set it in the battery charger. After setting, charging of the battery is usually completed after about 1 to 2 hours, so remove the battery from the battery charger and attach it to the camera body. Then, remove the plug of the battery charger from the AC outlet and store the battery charger. This completes a series of battery charging operations.

■Furthermore, the battery coupler mentioned above in (■), for example, as disclosed in Japanese Utility Model Application Publication No. 61-100078, attaches the mounting plate of the video light to the mounting shoe of the camera body, and the video light provided on the mounting plate is Connect the contact on the side and the contact on the camera body side provided on the mounting shoe to turn on the camera body's battery.

Moreover, the battery coupler shown in FIG. 17 has a casing lO
Two halogen lamps 12 are provided at the front of the casing, and a video light battery 14 is provided at the rear of the casing 10. Video light battery 14 and halogen lamp 1
2, the mode changeover switch 16 provided on the casing 10 is operated to enter the energized state or the energized state. Note that 18 is a switch for switching between lighting one halogen lamp 10 and lighting two halogen lamps, and 20 is a lock lever for the video light battery 14.

A mounting plate 22 is provided below the battery coupler constructed in this way, and the battery coupler is mounted to a mounting shoe (not shown) of the camera-integrated VTR main body via this mounting plate 22.

In addition, the battery coupler shown in Fig. 17 has a connector cord 2.
4 is provided, and this connector cord 24 is connected to a terminal (not shown) of a camera-integrated VTR to receive an electric signal from the camera-integrated VTR, and the halogen lamp 12 can be lit by the received electric signal. Therefore, for example, when the camera-integrated VTR is in the "standby" or rRECJ state, the halogen lamp 12 is automatically turned on.

[Problem to be solved by the invention]

However, the above-mentioned problems (1), (2), and (2) have the following problems.

Regarding (2), recently there has been a remarkable downsizing of VHS-C type and 8*1 videos, and due to the downsizing, there are some that are not provided with a shoe for attaching accessories. Therefore, even if the photographer wants to obtain good image quality and good tone, or even if he wants to enjoy both videos and skill images as necessary, the camera must be equipped with a battery coupler, a high-performance microphone, a silver halide camera, etc. The problem is that it cannot be installed on the

The present invention was made in view of these circumstances, and allows a battery coupler, high-performance microphone, or simple box-type camera to be attached to an 8-fight video etc. that does not have a shoe for attaching accessories. The purpose is to provide a battery coupler.

■In order to simplify the series of battery charging operations mentioned above,
It is conceivable to incorporate a battery into the camera body, or even incorporate a battery charger along with a battery. In this way, it is possible to omit the attachment and detachment of the buff battery, thereby simplifying the charging work.

However, when a battery and a battery charger are built into a camera-integrated VTR, there is a problem in that it is not possible to take pictures for a long time because it is not possible to replace spare batteries one by one when shooting continuously for a long time.

On the other hand, devices that integrate a battery and a battery charger have already been proposed, but this poses a problem for photographers who use multiple batteries because each battery has a battery charger, which increases the price. .

Furthermore, when shooting for long periods of time, it is possible to use six AA batteries in the battery case, but in this case, it is necessary to carry the battery case separately from the camera body, which poses a problem with portability. .

The present invention has been developed in view of the above circumstances, and can simplify the battery charging work, and can also be adapted to long-term shooting in which multiple batteries are sequentially used. An object of the present invention is to provide a battery coupler that does not require carrying a battery case.

Regarding ■, recently there has been a remarkable downsizing of VH3-C type and 8mm video cameras, and with this downsizing, the battery capacity used for these can be reduced, so the battery coupler is turned on when using the camera's battery. The problem is that it is not possible.

Furthermore, the amount of electricity of a battery coupler with a battery as shown in Fig. 17 is approximately 300g to 500g, and if it is attached to the mounting shoe of a miniaturized camera-integrated VTR, it will be installed relatively at the top of the camera-integrated VTR. So,
There is a problem in that the weight balance becomes poor and stable images cannot be taken.

Furthermore, the mounting shoe provided on recent small-sized camera-integrated VTRs is configured so that only lightweight objects such as external microphones can be attached, or small-sized camera-integrated VTRs that are not equipped with a mounting shoe. Therefore, there is a problem in that a battery coupler cannot be attached to this type of camera-integrated VTR.

Furthermore, since the connector cord 24 is required to control the lighting of the halogen lamp 12, the connector cord 24 becomes a hindrance when carrying the device, resulting in a lack of portability.

The present invention was developed in view of the above circumstances, and an object of the present invention is to provide a puffer coupler equipped with a video light that is compatible with a small-sized camera-integrated VTR such as an 8 mm video camera.

Next, the battery coupler shown in FIGS. 11 to 16 will be explained in detail.

FIG. 11 shows a state in which a sixth embodiment of the battery coupler according to the present invention is attached to a camera body 330 of a small 8 mm video camera. The rear of the camera body 330 is the camera body 33
A battery 334 that operates 0 is configured to be removable and connectable to an electric circuit within the camera body 330.

A coupler 336 of the battery coupler 332 is attached to the rear of the camera body 330 configured in this manner.

Therefore, the attachment part of the coupler 336 to the camera body 330 is configured the same as the attachment part of the battery 334, and the coupler 336 is attached to the camera body 330.
The rear part of the camera body 336 has the same structure as the rear part of the camera body 330 so that a battery 334 can be attached thereto.

A light case 338 is integrally formed with this coupler 336, and a halogen lamp 340 is provided inside the light case 338. Further, the light case 338 is provided with a mode changeover switch 342, and the light case 338 is further provided with a mode changeover switch 342.
A video light battery 344 is removably attached to the rear of the camera. Therefore, the battery coupler 332 constitutes a video light unit.

In FIG. 11, 346 is a photographing lens, 348 is an electronic viewfinder (EVF), and 350 is a grip band.

FIG. 12 shows an electric circuit of the battery coupler 332 of the sixth embodiment shown in FIG. 11. Battery coupler 332 is the first
When installed between the camera body 330 and the battery 334 as shown in FIG. 1, the terminal 330 of the camera body 330
A, 330A and terminal 336A of battery coupler 332,
336A is connected to the terminal 33 of the battery coupler 332.
6B.

336B and terminals 334A, 334A of the battery 334 are connected. This battery coupler can switch between constantly lighting the halogen lamp 340 and automatically lighting the halogen lamp 340 when photographing by detecting the current of the camera body 330 by operating the mode changeover switch 342.

That is, when the changeover switch 342 is set to the "ON" position in FIG. 12, the light battery 344 and the halogen lamp 340 become a closed circuit, and the halogen lamp 340 lights up. Also, when the mode selector switch 342 is set to the "remote" position and the camera body 330 is set to rREC, the coil 351 is energized and the switch 352 is turned on.
comes into contact with plate 354. In this way, the coil 351
When the relay switch 1 switch 352 and the plate 354 are operated, the voltage of the light battery 344 is applied to the halogen lamp 340, and the halogen lamp 340 is automatically turned on.

In FIG. 12, the lighting of the halogen lamp 340 is controlled by a relay switch, but as shown in FIG.
62, an operating amplifier 363, and a transistor 365 may detect the current flowing through the camera body 330 to control blinking of the halogen lamp 340. First, the camera body 33
0, the magnetic force from the electromagnet 360 acts on the Hall element 362, and from the Hall element 362 the operating amplifier 3
A current flows through 63. Furthermore, current flows through the operational amplifier 363 via a resistor 364. A current value is preset in the operational amplifier 363, and when the difference between the current from the Hall element 362 and the current from the resistor 364 becomes larger than the preset value, the operational amplifier 356 transfers the current to the transistor 3.
65, current flows from the light battery 344 to the halogen lamp 340, and the halogen lamp 340 lights up.

Therefore, by making it possible to adjust the value of the resistor 364 from the outside, it is possible to set the volume of the resistor 364 suitable for the camera body. For example, if the current flowing to the camera body 330 is 920 mA during recording (REC) and 800 mA during recording standby, adjust the volume of the resistor 364 to select either rREcJ or "standby" and use the halogen lamp 340. You can set the lighting time.
