にピン5が植設された円板である。In view of the above-mentioned problems, the present invention has been provided with a first gear actuating member that is energized in conjunction with the winding operation of the winding member, and a first lever actuating member that releases the lock in conjunction with the return movement of the winding member. A locking member, a second locking member that unlocks the seventh action member in conjunction with the pressing down operation of the release member, and a holding member capable of holding the release member in a pressed down state, The camera shutter enables continuous manual shooting by energizing and releasing the shutter operating member by operating the winding member while the release member is held in a depressed state by a holding member. This is intended to provide a release mechanism, and this will be explained based on an embodiment shown below. Fig. 1 shows a state in which the winding lever is in the middle of returning, and ■ indicates a rotation shaft 2 (not shown). A winding lever 4 is fixed to the upper end of the winding spool (which is connected to the winding spool that is not connected via a ratchet mechanism) and is given right-handed rotation by a spring 3; 5 is the implanted disc.

る。The shutter release mechanism according to the present invention is constructed as described above, and in the normal state (photographing end state), the shutter operating lever 10 is locked by the second locking pawl 22 as shown in FIG. Now, in this state, roll ``Nige Lever 1''
When the shutter actuating lever 1 is rotated to the left, the pin 15 separates from the intermediate lever 15 at the initial stage, and as a result, the intermediate lever 15 is rotated to the right, and the first locking pawl 17 is rotated to the left and the shutter actuating lever 1 is rotated.
Lock 0. Then, in the next step, the return lever 6 stores the springs 7 and 11, is turned to the left, and is locked by the lock pawl 8. Next, by stopping the winding operation of the winding lever 1, the winding lever 1 returns to its original position by the spring 3, that is, rotates to the right, and the second
As shown in the figure, the pin 5 rotates the intermediate lever 15 to the left, so the first locking pawl 17 rotates to the right to release the lock from the shutter operating lever 10. Next, the holding plate 24
While holding it in the position shown by the solid line in Figure 1, press the release lever.
19 is pressed down with a finger, the intermediate lever 21 is rotated to the left as shown in FIG. 2, and the second locking pawl 22 is rotated to the right to release the lock of the shutter operating lever 10, and as a result, the shutter is activated. member 10 is spring 1
1, the mirror drive lever I2 is rotated to the left and the flip-up mirror 14 is rotated upward.

3による右旋力により元の位置に復帰せしめられる。Incidentally, although not shown in the drawings, the opening and closing operations of the seven-yield door are performed in conjunction with these mechanisms through a well-known mechanism. Thus, when the opening/closing operation of the shutter is completed, the lock pawl 8 is rotated to the left via a well-known interlocking mechanism (not shown) to release the lock from the return lever 6, so that the return lever 6 is returned to its original position by the spring 7 (fc). The spring 1 of the mirror 1 drive lever 12 is returned to the /Yanotar operating lever IO by loosening the spring 11.
The right turning force caused by 3 causes it to return to its original position.
そして、レリーズレバ−19から手指を離すと該レバー

0を係止する。When you release your finger from the release lever 19, the lever 19 returns to the raised position by the spring 20, and the second locking pawl 22 returns to its original position, causing the shutter actuating lever to
Lock 0.

能と々る。Next, with the release lever 19 pressed down, hold the holding plate 2.
4 is rotated to the left, the bent arm portion 24a engages with the protrusion 19a from above as shown in FIG. The state is such that the shutter operating lever 10 is always released from the lock. Therefore, if the winding and returning operations of the winding lever 1 are repeated in this state, the shutter operating lever 10 will be locked, biased, and unlocked as described above.
Since the return is repeated sequentially, continuous manual shooting is possible.
又、レリーズレバ−19が上昇位置にある状態で保持板
24を左旋せしめると、第1図鎖線図示の如くその折曲
腕部24aが突部19aに下側から係合するので、レリ

、不用意にレリーズ1/ /< −1,9を押してもシ
ャッターレリーズが行われないので、大変便利である。Furthermore, when the holding plate 24 is rotated to the left with the release lever 19 in the raised position, the bent arm 24a engages with the protrusion 19a from below as shown by the chain line in FIG. It becomes impossible to push down. Therefore, even if the release button 1//<-1, 9 is pressed inadvertently, the shutter release will not be performed, which is very convenient.
上述の説明で明らかな如く、保持板24はカメラを−・
枚撮りの状態と連続撮影可能の状態とに切り換えるため
の切換手段としての機能を有するため、クリック機構等
により一旦切り換えられた位置は妄シには動かないよう
になっている。As is clear from the above explanation, the holding plate 24 holds the camera.
Since it functions as a switching means for switching between a state of taking pictures and a state of being able to take continuous pictures, the position once switched by a click mechanism or the like cannot be moved inadvertently.
上述の如く、本発明によるカメラのンヤツターレリーズ
機構によれば簡単な切換え操作により、手動による連続
撮影が可能となるので、カメラの構造が複雑にならず低
コストの−itで済むと云う優れた利点を有する。As mentioned above, the shutter release mechanism of the camera according to the present invention enables manual continuous shooting with a simple switching operation, so the structure of the camera does not become complicated and can be done at low cost. Has excellent advantages.
