Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a winder grip attached to a camera having a winding connecting portion for connecting a winding member on a side surface of a camera body and a multiple exposure switching member for switching between a single exposure mode and a multiple exposure mode.

[0002]

[Prior art]

 Conventionally, a winding connection knob of this type of camera body is usually equipped with a winding knob with a crank as a winding member, and the multiple exposure switching member can be easily switched between a single exposure mode and a multiple exposure mode. However, if a winder grip is attached instead of the winding knob to improve the holding and mobility of the camera, the attached winder grip may completely cover the multiple exposure switching member. Therefore, it is necessary to provide on the winder grip side a remote switching mechanism capable of operating the multiple exposure switching member on the camera side and a display section showing the switched exposure mode.

[0003]

[Problems to be solved by the device]

 However, in such a conventional winder grip, a guide portion for connecting and attaching to the winding connection portion on the camera side, a lock portion, a drive motor with a reduction mechanism for rotationally driving the winding connection portion, and the same. It is usually equipped with a power supply, a release button and its lock member. Therefore, it is extremely difficult to provide the above-mentioned remote switching mechanism and the display section showing the exposure mode on the remaining small space, and the provision of these makes the winder grip larger and heavier, and the holding property and This may impede maneuverability and lead to cost increase of the product.

Therefore, if the distance switching function of driving the multiple exposure switching member on the camera side from the winder grip and the display function thereof are omitted, the switching state of the multiple exposure switching member on the camera side when the camera is equipped with the winder grip. Could not be confirmed, so there was a risk that I would inadvertently switch to the multiple exposure mode while wearing the winder grip and all subsequent shooting would fail.

In order to prevent such a failure, the film counter does not advance in the multiple exposure mode so that the film counter can be checked at the time of winding, or the winder grip can be temporarily removed to perform multiple exposure on the camera side. There is no choice but to check the setting position of the switching member, but if you are crazy about shooting, it is almost impossible to do such extra operation. The present invention has been made in view of the above points, and an object thereof is to enable the user to easily confirm the multiple exposure switching state from the outside when the winder grip is attached with a simple structure.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention has a winding connection part for connecting a winding member and a multiple exposure switching member provided with projecting ribs on the side surface of the camera body, and the multiple exposure switching part is provided at the winding connection part. A winder grip mounted so as to cover the switching member, wherein the operation rib is loosely fitted at the single exposure mode setting position of the multiple exposure switching member, and the operation rib intersects at the multiple exposure mode setting position. And an exposure mode detection member that is displaceable in the axial direction of the multiple exposure switching member, a switching detection lever that can swing a predetermined angle in conjunction with the displacement of the exposure mode detection member, and a free end portion of the switching detection lever. The present invention provides a winder grip provided with an identification portion formed on the outside of the multi-exposure switching member so that the switching state can be visually recognized from the outside.

Further, the body has a winding connection portion for connecting the winding member and a multiple-exposure switching member provided with a projecting rib on the side surface of the body, and is mounted on the winding connection portion so as to cover the multiple-exposure switching member.

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings. FIG. 1 is a perspective view showing a cutaway part of an embodiment of the present invention, FIG. 2 is a perspective view showing a display side in an exposure mode switching state, and FIG. 3 is a camera to which the winder grip is attached. FIG. 4 is a perspective view showing a configuration on the body side, and FIG. 4 is a perspective view showing a winder grip mounted state.

First, the structure of a camera body to which the winder grip according to the present invention is attached will be described with reference to FIG.

This camera is a 6 × 4.5 cm electronically controlled focal plane shutter single-lens reflex camera, and the lens, film holder, finder, finder screen, winding member, etc. are all replaceable. On the left side when viewed from the front of the camera body 1, in order from the top, the shutter speed dial 2, the winding connection part for mounting the winding member such as the cranking hoisting knob and winder grip 3, single exposure mode and multiple exposure A multiple exposure switching member 4 for switching between modes and is provided.

The multiple-exposure switching member 4 is provided with a manual operation rib 4a on the diameter of the surface, and by rotating it by about 90 °, the film is exposed only once on one screen and the film is exposed. Roll-up Single exposure mode shown in Fig. 3 and multi-exposure mode that allows multiple exposures on the same screen without film or film counter being fed only by charging shutters and mirrors by winding operation. You can FIG. 5 is an explanatory diagram showing a setting state of the multi-exposure mode.

The winding connection unit 3 charges the drive mechanism for the shutter, the mirror, and the aperture by rotating in the clockwise direction, and when the single exposure mode is set, the rotation interlocking plate 3a that advances the film counter by one frame along with the film, It is provided so as to surround the outer peripheral portion thereof, and includes a fixed mounting substrate 3b for mounting each winding member. The mounting board 3b is provided with a plurality of electronic information contacts 3c for transmitting information with the winder grip side. A bayonet mount 5, a shutter release button 6, and a battery check button 7 for lens replacement are provided on the front surface of the camera body 1, and a shoe shoe, a mirror up lever, a synchro terminal, a lens removal button, etc. are provided on the right side surface (not shown). Are provided respectively.

As shown in FIGS. 1 and 2, the winder grip 10 attached to the winding connection portion 3 of the camera body 1 having the above-described configuration has an upper portion of the grip body 11 and the grip body 11 forming an outer shell. A shutter release button 12 with a lock mechanism, a winding connection part 13 and an exposure mode detection part 14 which face the winding connection part 3 and the multiple-exposure switching member 4 on the camera body 1 side when mounted on the camera body 1. I have it.

The winding connection portion 13 includes a rotation drive plate 13a, an attachment guide plate 13b, and an electronic information contact corresponding to the rotation interlocking plate 3a, the mounting substrate 3b, and the electronic information contact 3c of the winding connection portion 3 on the camera body 1 side. 13c is provided, and is locked and unlocked by operating the lock member 13d.

The exposure mode detection unit 14 faces the multiple exposure switching member 4 in the state where the winder grip 10 is attached to the camera body 1, and the exposure mode detection member 15 is displaceable in the axial direction thereof. It comprises a switching detection lever 16 for transmitting the displacement of the exposure mode detection member 15 through an extension portion 15b extending integrally therewith. The switching detection lever 16 is axially attached to the bottom surface of the grip body 11 by a shaft 17 and is urged clockwise by a spring 18 in FIG. 1 to keep the exposure mode detection member 15 in a protruding state via an extension portion 15b. .

The operation mode detection member 15 is loosely fitted with the operation rib 4a which is in a horizontal state when the multiple exposure switching member 4 on the camera body 1 side is set to the single exposure mode, and the multi exposure mode is set. The groove portions 15a are provided so as to intersect with each other in a vertical state. Further, the switching detection lever 16 is provided with an arcuate discriminating portion 16a centered on the shaft 17 at its free end, and the back surface thereof is divided into two colors, for example, a white portion 16a 'and a red portion 16a ", and the bottom portion of the bottom is formed. Either of them can be visually recognized from the display window 19.

With the above configuration, when the winder grip 10 is mounted when the multiple exposure switching member 4 of the camera body 1 is set to the single exposure mode and the operating rib 4a is in the horizontal state, the exposure mode detection is performed. The operating rib 4a of the multiple-exposure switching member 4 is loosely fitted in the groove portion 15a provided in the exposure mode detection member 15 of the portion 14. As a result, the detection member 15 is not pressed by the multiple exposure switching member 4, the switching detection lever 16 does not rotate, and the white portion 16a 'of the identification portion 16a is displayed in the display window 19 and the camera body 1 is displayed. It can be seen that the multiple exposure switching member 4 on the side is set to the single exposure mode that prevents multiple exposure.

Further, when the winder grip 10 is mounted when the multiple exposure switching member 4 is set to the multiple exposure mode and the operating rib 4a is in the vertical state, the exposure mode detecting member 15 of the exposure mode detecting portion 14 is attached to the winder grip 10. The operating rib 4a of the multiple exposure switching member 4 intersects the groove 15a provided at a right angle. As a result, the exposure mode detection member 15 is pushed back by the operating rib 4a of the multiple exposure switching member 4, and the switching detection lever 16 resists the urging force of the spring 18 through the extension portion 15b to a predetermined angle. When it is turned counterclockwise at 1, the red portion 16a ″ of the identification portion 16a is displayed on the display window 19 to warn that the multiple exposure switching member 4 is set to the multiple exposure mode.

As described above, in the above embodiment, the winder grip 10 side is provided with only the display unit 19 indicating the exposure mode in which the camera body 1 side is set, and the configuration of the exposure mode detection unit 14 is significantly simplified. I did. Therefore, if it is found that the multiple exposure switching member 4 on the camera body 1 side is set to the multiple exposure mode after the winder grip 10 is attached, the winder grip 10 is once removed and the camera body 1 side is removed. It is necessary to reset the multiple-exposure switching member 4 to the single-exposure mode.

However, when the photographer uses the multi-exposure mode, the number of cases is extremely small compared to the case where the single-exposure mode for preventing multiple exposure is used. In the case of one, all of the subsequent shootings will result in failure if there is no warning means, so the effect is extremely large.

In the above-described embodiment, the display window 19 of the identification portion 16a of the switching detection lever 16 is provided on the bottom surface of the grip body 11. However, like the other embodiments shown in FIG. It is also possible to bend the identification portion 26a of the lever 26 substantially at a right angle so that the display window 29 is provided on the back surface of the grip body 11, and by doing so, the display at the normal photographing position is performed. The window 29 can be easily visually recognized.

Further, as in yet another embodiment shown in FIG. 7, the switching is closed by being biased by the spring 38 instead of the switching detection lever 16 and pressed by the detection member 15 in the protruding state. In addition to providing the detection switch 36, a display window 39 for an identification member such as an LED or LCD which is provided on the upper surface of the grip body 11 close to the shutter release button 12 and which blinks or lights when the switching detection switch 36 is closed is provided. By doing so, it is found that the multiple exposure switching member 4 on the camera body 1 side is set to the multiple exposure mode at the moment when the winder grip 10 is attached, and it is possible to prevent a photographing error from occurring.

[0023]

As described above, according to the winder grip according to the present invention, the winder grip can be changed to the setting exposure mode on the camera body side without increasing the size and weight of the winder grip with a very simple structure. It can be easily confirmed from the outside without removing it, and accidental mistakes in shooting can be prevented. In addition, when the exposure mode detection member on the winder grip side, which is pressed when the camera body side is set to the multi-exposure mode, closes the normally open type changeover detection switch to blink the identification part, Can be set at the position where it is most noticeable, and further effects can be obtained.
