Abstract

The camera, especially for single-lens reflex camera features, which has a film cassette with a horizontal picture gate for landscape exposures and a vertical gate for portraits, under the condition of no rotation for the camera body, is installed to the camera body on the position of two comparatively corner 90 DEG C, and shoots horizontal or vertical picture selectively. The cassette housing contains a drive motor for transmiting film and film guide rails and film platen, and a slider, which closes the picture gate before the film cassette is withdrawn to the camera body, is set. The interfaces of film cassette and camera body are rotational symmetry locking forks and electrical contacts.

Description

Camera

The present invention relates to a kind of camera, especially a kind ofly optionally take in banner or the upright width of cloth formula or the single-lens camera of little picture photo.

The object of the present invention is to provide a kind of camera, it optionally takes banner or upright photos under the non-rotary situation of camera body.

Purpose of the present invention is achieved by following characteristic Design:

A) one has the optical film magazine that is used to take the pressure-bearing type image window of banner photo and is used to take the vertical image window of founding photos, it can install on the camera body on two relative rotations are 90 ° position when optionally taking banner or upright photos.

B) in cassette shell, pack into one CD-ROM drive motor that is used to transmit film and film rail plate and the film pressing plate that constitutes film channel.

C) in cassette shell, settle one can be at the slide plate of optical film magazine with close image window before camera body separates.

D) interface of camera body and optical film magazine constitutes the blocking device and the electrical interface of rotatable symmetry, at this interface, be contained in the blocking element and the electrical contact and complimentary to one another of magazine one side at the blocking element and the electrical contact of the setting of camera one side, wherein, perhaps camera one side or be in two cover blocking element and electrical contacts of 90 ° of corners in magazine one side setting.

If use the horizontal image window of optical film magazine, camera just can be taken the banner photo, on the contrary, when the optical film magazine half-twist was used its vertical image window, camera can be taken upright photos.Owing in the film cassette shell, be provided for transmitting the CD-ROM drive motor and the required element of guiding film of film, so the interface structure between camera body and the optical film magazine is simple especially.In order to realize 90 ° of rotation conversions of optical film magazine, require complementary blocking device and the electrical contact of two covers is being set on the camera body or on optical film magazine.

The slide plate that is integrated with optical film magazine can be rapid, closing image window simply, thus can carry out the rapid conversion or the replacing of optical film magazine.

The simple and reliable especially design proposal of the present invention can realize like this, and a square jack promptly is set at the back side of camera body, and it can hold the plug connector that is located on the cassette shell.

By a special slide plate design proposal of saving space and easy operating of the present invention, slide plate is a flexible structure, its slip capable of reversing and from the outside by mobile one handle, for example a cambered plate can make slide plate slide to and open or closed condition in cassette shell.

A same simplicity of design but reliably blocking device can realize like this that promptly described blocking device has the deflectable detent bracket that is provided with on two two opposite faces at the magazine housing on magazine one side.4 register pins that are mutually 90 ° of layouts are set on camera body one side.Its advantage is that detent bracket can deflection between two resiliently mounted inflection points, that is to say by optical film magazine is contained in or is pressed into to realize blocking in the camera body and realize off-state by only taking off optical film magazine from camera body.

In addition, suitable is, in the magazine side the best electrical interface of being made up of 6 contact rivets that is in 90 ° of corners of two covers is set, and in camera body one side one group of sheet spring contact only is set.

With regard to above-mentioned camera body, also can be regarded as a mirrored cabinet attachment device that can be contained on the camera housing.

Accompanying drawing is represented an embodiment as example of the present invention, wherein:

Fig. 1 is the vertical view of optical film magazine;

Fig. 2 is the rear view of optical film magazine shown in Figure 1;

Fig. 3 is an optical film magazine shown in Figure 1, and it has some parts that dot; With

Fig. 4 is the rear view of camera body.

Fig. 1, optical film magazine 1 of 2 and 3 expressions, it can be contained in the back side of camera body 2 shown in Figure 4.This camera body that only schematically shows 2 also can be a mirrored cabinet attachment device that can be connected on the camera case.Be provided with a square jack 3 at the back side of camera body 2, it can hold the plug connector that is located on the cassette shell.

Interface 3,5 between camera and the film cassette constitutes a blocking device and electrical interface of rotatable symmetry.But blocking device is arranged on be in magazine one side two on deflection detent bracket 6 (see figure 1)s on magazine housing 4 opposite faces, this detent bracket can deflection between two resiliently mounted turned positions.On two detent brackets 6 on camera side, be provided with two pairs of register pins 7,7 that are in 90 ° of corners '.The detent bracket 6 that Fig. 1 and Fig. 3 are illustrated in that plug connector 5 tops or middle position be provided with when being in off-state, detent bracket is a flat spring bracket.When plug connector 5 is inserted the jack 3 of the camera body that matches with it, mutual opposed a pair of register pin 7 or 7 ' slip in the support holes that is located on the detent bracket 6 and in the film cassette that further will have plug connector 5 inserts jack 3 time, detent bracket deflects to a resiliently mounted blocking in the square jack 3 of camera body.When this state, the register pin 7 or 7 that these two detent brackets 6 will match with it from behind ' tightly locking is lived.By only taking off film cassette 1 from camera body 2, the detent bracket that register pin 7 or 7 ' complete atresia are lived in the front deflects into off-state again.Thereby film cassette 1 elastic atresia to camera body 2 time, do not need the manual operation that adds, but realize the installation of film cassette 1 on camera body 2 automatically, wherein, can realize unclamping automatically of elastic atresia again by only taking off film cassette.

About electrical interface, exactly in the upper surface of plug connector 5 (see figure 1)s and a side (see figure 2) that becomes the plug connector 5 of 90 ° of corners with it, preferably respectively load onto 6 the

contact rivets

8 or 8 '.And in camera body one side, then a side at square jack 3 is provided with 6 sheet spring contacts 9.

The plug connector 5 of film cassette 1 is holding a rectangular image window 10, this image window can be taken the banner photo when it is horizontal, when its vertical placement, can take upright photos, this image window 10 can be closed by the slide plate 11 that a flexibility is set, and this slide plate slidably arrives its unlatching or closed condition through commutation in cassette shell 4.By moving a cambered plate 12 that reaches the outside from cassette shell 4, slide plate is slided along groove.Dotted the slide plate 11 when making image window 10 be positioned at free opening among Fig. 3.By moving cambered plate 12 along direction shown in the arrow 13, slide plate is slided on image window 10, can close the inner chamber of cassette shell 4 like this, make it close light tight.

In Fig. 3, dot some parts in the film cassette 1, wherein be provided with a bobbin 14 and match with it by the coil 15 of CD-ROM drive motor 16 by breast wheel 17 transmissions.Transmit in the film film channel that constitutes by film rail plate and film pressing plate usually not shown further in the drawings.

By accompanying drawing as can be known, film cassette 1 can be assemblied on the position of the 90 ° of corners of two one-tenth on the camera body 2, so that optionally take banner or upright photos.

Cassette shell 4 is equipped with a turnover backboard 4a, and the cambered plate 12 that slide plate is carried out slide is packed in this backboard.
