Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera which can be easily operated by holding it vertically and horizontally, and camera accessories such as a motor drive device and a vertical holding grip, and a camera body and camera accessories. The present invention relates to a connector device for electrically connecting to and.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 21, a connector for electrically connecting a camera and accessories such as a motor drive device has a contact 201 fixed to a camera body 200,
The contacts 20 of the connector are arranged so as to be energized by the contact of the contact pins 204 arranged in the accessory 202 and biased by the coil spring 203 in the protruding direction.
1 and the contact pin 204 are not misaligned, and the contact pin 204 is prevented from being damaged due to excessive stress when it is attached or detached.
The contact between No. 1 and the contact pin 204 was made smooth.

Conventionally, the operation member for inputting information of the camera is laid out in consideration of only photographing at the time of holding the camera in the normal position (horizontal position), and the only camera to which accessories such as a motor drive can be attached and detached. In the above, the motor drive device is configured to have only the release button.

[0004]

However, the conventional camera and the connector structure of the camera have the following drawbacks.

(1) Since the contact pins are configured to slide up and down, a space of a certain size is required for each pin due to an internal mechanism or the like, and there is a positional deviation between the contacts and the contact pins. Since it is necessary to make the contacts larger in order to absorb the light, it is difficult to make multiple contacts on the limited area of the bottom surface of the camera.

(2) Since the contact pin is abutted against and brought into contact with the contact, if dust or rust adheres to the contact, contact failure occurs.

(3) The contact pressure varies depending on how the camera and accessories are attached, resulting in lack of contact stability.

(4) Even when the camera is held in the vertical position for photographing, it is necessary to hold the grip in the horizontal position and input information using the operation member for the horizontal position. Since the holding stability at the time is lacking, camera shake etc. will occur and it will lead to failure of photography.

The present invention solves such a conventional problem, has good operability even if the camera is held in the vertical and horizontal directions, and has electrical connectivity between the camera body and accessories detachably attached to the camera body. An object of the present invention is to provide a good connector device.

[0010]

The structure for achieving the object of the present invention is as set forth in the claims, and specifically, a first (normal position) grip portion for holding a camera, A first (for normal position) information input operation member group disposed in the vicinity of the 1 (normal position) grip portion;
A second (vertical position) grip portion, which is arranged so as to be substantially perpendicular to the (normal position) grip portion and has substantially the same shape as the first (normal position) grip portion, and a second (vertical position) grip portion. A second (vertical position) information input operation member group disposed near the grip portion and having substantially the same function as the first (normal position) information input operation member group, and a first (normal position) Of the first gripping section and the first (for normal position) information input operation member group and the second (vertical position) grip section and the second (for vertical position) information input operation member have substantially the same layout relationship. In relation, again, second
By making the (vertical position) grip part and the second (for vertical position) information input operation member group detachable from the camera, the camera can be stably held when the vertical position photo is taken, and the normal position can be maintained. You can get the same operability as when shooting.

In addition, in a connector for electrically connecting a camera and accessories of the camera, one is a convex-shaped electrode portion in which a plurality of electrodes are arranged in a straight line, and the other is a concave type in which a plurality of electrodes is arranged in a straight line. A connector having a shape-shaped electrode part, in which the convex electrode part is inserted and fitted into the concave electrode part to carry out contact electric current, and one or both of the connectors are held by an elastic member and attached to a camera. The connector electrode portion arranged has the plurality of electrodes arranged so as to be substantially parallel to the line connecting the attachment means to the camera and the positioning means, and the connector electrode portion of the camera. By setting the electrode part to a height that does not project beyond the line connecting the apex of the attachment means to the camera and the apex of the positioning means, can the accessory with a multi-contact connector be smoothly attached to the camera? It is obtained to ensure the mounting so.

Moreover, the holding in the vertical position is surely taken,
It has the effect of preventing camera shake and allowing vertical shooting without failure.

Further, the connector device of the present invention has the following effects.

(1) While the camera and accessories are being attached, even if the camera is tilted to the left or right, an unreasonable force is not applied in the thickness direction of the connector, and the electrode of the connector causes only a displacement in the pitch direction. , The pressure of the contact part becomes constant, and there is an effect of preventing damage and stabilizing energization.

(2) By holding the connector with rubber, the connector can move freely, the contact points of the electrodes during insertion are stable, the pitch of the electrodes can be reduced, and multiple contacts can be made.

(3) When inserting, the contacts are connected while sliding, so that the contacts have a self-cleaning effect.
Contact reliability is improved.

(4) Even if the camera is tilted to the left or right while the camera and accessories are being attached, the connector is damaged because the bottom surface of the camera does not come into contact with the connector due to the attachment means and the positioning means of the camera. It will prevent.

(5) Since the connector is held by rubber, it absorbs the positional deviation between the connector electrodes due to manufacturing errors or the like and the stress caused by unreasonable insertion at the time of mounting, and ensures reliable contact after mounting (insertion). Guarantee.

(6) The electrode insertion portion is located higher than the camera mounting surface, and the rubber holding the connector seals the periphery of the connector, so that water and the like can be prevented from entering and an excellent waterproof effect can be obtained. Hold.
