Abstract

PURPOSE:To make a titled camera execute a constant photographing operation without requiring a charging operation, and also to make it easily portable, by forming it so that a primary battery power supply pack is loaded to a camera body, in the lower part from the center of a portable video camera body. CONSTITUTION:An installing part 5 of an electric power supply pack 6 of a primary battery 8 is loaded to a lower part 7 from the center of a video camera body 1. The primary battery 8 consists of, for instance, a cylindrical lithium battery, an air battery, an alkali manganese battery, etc., and is formed to high voltage and high capacity by connecting suitable pieces in series or series- parallel in conformity with power consumption and voltage, etc. A positive pole terminal 10 and a negative pole terminal 11 are formed so as to be exposed to a part of the electric power supply pack 6, and it is loaded normally to the installing part 5 of the lower part 7 of the camera body 1 by a guide 12 provided on both sides of the electric power supply pack 6, by which photograhing can be executed.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a vertical video camera in which a primary battery power source for video operation is integrally formed below the center of the vertical video camera body.

Votaple video camera is a combination of camera and video,
In other words, color video cameras and ultra-compact video cameras are being integrated to make them smaller and lighter. This is due to advances in semiconductor technology, which have led to higher integration and multi-functionality, and high-density packaging technology has led to smaller and lighter video recorders.

However, conventionally, a lead-acid battery or a nickel-cadmium storage battery has been used as the operating power source for a video camera, and the power source battery is packed together with a charger and connected to the video camera body separately by a connecting wire. Secondary batteries can be used for long periods of time by repeatedly charging and discharging them, but charging them is inconvenient, and if you forget to charge them, the camera may not work in an emergency situation. In addition, secondary batteries require a charger, are large in size, and are extremely inconvenient to carry due to their weight.

On the other hand, for primary batteries, research into new electrode systems and structures has progressed, and research into battery materials has recently led to the development of small, high-performance batteries, such as lithium batteries, air batteries,
Alkaline batteries have an extremely large electrical capacity compared to conventional manganese dry batteries.

In the past, the possibility of using a secondary battery-powered video camera was not considered at all because the electric capacity of secondary batteries had increased, and the power consumption of the secondary battery-powered video camera had decreased. Tuple video cameras are now possible. The present invention is a dual video camera using a primary battery as a power source, and furthermore, the power source is integrated with the camera, and
It is characterized by being loaded below the center of the camera body.

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

In the figure, 1 is the video camera body, 2 is the finder,
3 is a lens part, 4 is a video tape insertion part, 5 is an insertion part for a primary battery power pack 6, which is loaded in the lower part 7 from the center of the video camera body l, 8 is a primary battery, for example, cylindrical in shape. The battery is made up of lithium batteries, air batteries, alkaline manganese batteries, etc., and an appropriate number of batteries are connected in series or in series and parallel using lead wires 9 according to power consumption, voltage, etc., to achieve high voltage and high capacity. Reference numeral 10 denotes a positive terminal, and 11 denotes a negative terminal, which are formed so as to be exposed in a part of the power pack 6. Guides 12 provided on both sides of the power pack 6 allow the insertion portion of the lower part 7 of the camera 2 body 1 to be properly inserted. By loading the camera into the camera, you can take pictures.

As described above, in the multiple video camera of the present invention, the power pack 6 is loaded in the lower part 7 from the center of the camera body 1, so the operation of the video camera body 1 is stable, shooting is easy, and there is less fatigue. The tape and each component can be easily installed, the power pack 6 can be easily inserted and inserted, and the design effect can be improved. In addition, the power pack 6 is a primary battery 8
Because it uses a secondary battery as the power source, unlike conventional products, there is no need to charge it before use or the situation where the camera becomes unusable during shooting due to insufficient charging. In addition to eliminating the inconvenience of charging, secondary battery power supplies do not necessarily require a charger, there is less worry about battery accidents or running out of capacity, and they can be supplied at low cost.

The primary batteries used in the present invention include highly reliable and high-capacity lithium manganese dioxide batteries, lithium fluorocarbon batteries, lithium copper sulfide batteries, lithium thionyl chloride batteries, lithium iron sulfide batteries (lithium batteries such as ponds, zinc batteries, etc.). The negative electrode is used as a catalyst such as manganese monoxide or cobalt phthalocyanine, and the power source is an air battery or an alkaline manganese battery.

As described above, the portable video camera of the present invention is characterized in that the primary battery power source is integrally formed below the center of the main body, so it is easy to handle as there is no charging operation.
What's more, the operation during shooting is stable, and since the camera and power supply are integrated, it is easier to carry, making it extremely effective.
