Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a self-timer built into a camera.

For cameras equipped with a self-timer, regardless of whether the self-timer is used or not, it is preferable that the release button be operated in the same place, for example, the release button. Cameras that use different release buttons are cumbersome to operate and are prone to erroneous operations.

In addition, so-called electric shirts, in which exposure is controlled by an electric control circuit controlling the operation of a magnet, are constructed so that a power switch is opened and closed to cause the leash operating member to move, but a self-timer is also used. It is undesirable to leave the power switch on after you use the camera and release the camera until you finish shooting, as this will consume a lot of battery power.

Therefore, even if a self-timer is used, it is desirable to turn on the power switch shortly before the shirt release. If the secondary structure were to satisfy all the conditions desired in a self-timer built into a camera as described above, the structure would be extremely complicated and bulky.

The present invention provides a self-timer that satisfies all the desirable conditions in a self-timer built into a camera as described above, and which is extremely simple and compact.

The gear 16a is a timer sector gear having a semicircular pin 16b projected through the slot 2c and into the upper part of the timer upper plate 2. The gear 16a is connected to the pallet pallet 14 via a gear train.

The gear train that is engaged with the timer sector gear 16 is provided with a ratchet mechanism, not shown, which is known in the art for camera self-timers using this type of gear governor. When the ratchet mechanism restrains the pallet 14 and turns the timer sector gear 16 to the left, the gear train between the ratchet mechanism and the pallet 14 does not operate at all, and the gear train between it and the timer sector gear 16 operates very slowly. On the other hand, timer sector gear 16
It is made impossible to rotate to the right. 19 is the axis 20

Pin 24a sliding inside b, the timer upper plate 2
a slot 24b into which the pin 2d slides, a barge 24c that engages with the part 19f of the timer release lever 19,
Parts 24d and 24e that engage with the pin 16b of the timer sector gear 16, a pin 24f that is coaxial with the pin 24a and engages with the parts 21a, 21b, and 21c of the timer lock lever 21, and a cover 12d of the release operation lever 12.
It has a part 24g that engages with the timer upper plate 2 with the pin 24a and the slot 24b.
The pin 24a is connected to the slot by the pin 2d, which allows it to operate in the vertical direction, and when the pin 24a is lowered, the pin 24a can rotate by sliding in the slot 2b using the pin 2d as a fulcrum, and the spring 25
This is a timer actuating lever that is given a descending property by the spring 28 and a dextrorotatory property using the pin 2d as a fulcrum by the spring 28.

Note that the timer operating lever 24 can be operated by either the spring 25 or the spring 28 alone. Next, the operation will be explained.

FIG. 1 shows that the shirt is charged and the self-timer is in a state before being charged, that is, in a stationary state.

First, the case where the camera release operation is performed in the state shown in FIG. 1 will be described.

In the illustrated state, by operating the camera release,
The release operating lever 12 is operated to slide upward.

By this upward sliding operation, the release operating lever 12 engages the springy movable rear piece 13a of the power switch 13 with its barb 12d, and further pushes the part 19b with the barb 12c to rotate the timer release lever 19 to the left. , Next, press the part 9b with the machete 12c, and at the same time bring the movable bale piece 13a into contact with the fixed piece 13b to turn on the power switch 13 of the exposure control circuit (not shown), and then operate the slide upward. By continuing, the shirt shutter release lever 9 is rotated to the left to remove the part 9a from the sleeve 6a, and the left rotation of the shirt shutter drive lever 6 is prevented. As a result, the shutter drive lever 6 is rotated to the left by the drive spring 8, and a shutter opening/closing mechanism (not shown) is operated to perform exposure. When the shutter release operation is completed and the shutter release operation is completed, the shutter release operation lever 12 is pushed by the movable pocket piece 13a of the power switch 13 by its spring property, and the shutter release operation lever 12 is lowered and returned to its original position. The timer release lever 19 also returns to the left rotation position by the spring 23 of the timer lock lever 21, and the part 19e is pushed by the armature 21d, so that the timer release lever 19 returns to the right rotation.

To charge the shirt, turn the shirt drive lever 6 to the right against its drive spring 8 to charge the shirt 6a.
This is done by engaging the parts a, thereby returning each member to the state shown.

Next, in the state shown in FIG. 1, the self-timer charging operation and the resulting operation will be described.

Charging of the self-timer is performed by turning the timer sector gear 16 to the left against its spring 18.

The timer sector gear 16 rotates counterclockwise to rotate the pin 16.
Press part 24d with b to slide the timer operating lever 24 upward.

The timer operating lever 24 slides upward against the spring 25, and the pin 24f slides on the part 21a of the timer lock lever 21. When this is released, the timer lock lever 21 is rotated to the left by the spring 23, and the part 21c moves against the pin 24f. The left rotation is inhibited by engaging with.

When the timer operating lever 24 slides upward, its part 24g does not engage with the armature 12d of the shutter operating lever 12 at all. The timer lock lever 21 pushes the part 19e with the barb 21d by turning to the left, and turns the timer release lever 19 to the right. The operation of the Gatrain is suppressed by bringing it into contact and suppressing its operation.

When the timer operating lever 24, which is slid upward by the pin 16b of the timer sector gear 16, is operated until the pin 24f is removed from the part 21a and engaged with the part 21c, the pin 16b is removed from the part 24d at the same time.

As a result, the timer actuating lever 24 tries to descend by the spring 25, but the pin 24f engages with the part 21b, and therefore the descending is inhibited. The timer sector gear 16 continues to rotate to the left, and the pin 1 is inserted into the slot 2c.
6b is restrained by engaging. This left rotation is performed by idling a ratchet mechanism (not shown) provided in the gear train of the self-timer. The self-timer is charged as described above.

Next, the operation of the shutter release and self-timer by the release operation in the fully charged state will be explained.

The release operation when the self-timer is charged is performed by pushing up the release operation lever 12 against the springiness of the movable contact piece 13a of the power switch 13, similar to the release operation when only the shirt cover is charged. It will be done.

In this case, the operating stroke of the release operation lever 12 is regulated by the timer release lever 19, and before turning on the power switch 13 with the bar 12d and pressing the part 9b with the bar 12c. will be suppressed. That is, the corresponding lever operation lever 12 is operated to slide upward, and the lever 12c
When the timer release lever 19 is rotated to the left, the timer release lever 19 is engaged with the part 19b before the lever 12c is engaged with the part 19b.
c engages with the pin 16b of the timer sector gear 16 to prevent it from rotating to the left. By turning the timer release lever 19 to the left, the armature 19a is released from the part 14a, thereby releasing the restraint on the pallet release lever 14a. As a result, the ankle 1
The timer sector gear 16, which is connected to the gear train 4 through the gear train, begins to rotate to the right. The timer release lever 19 also pushes the lock lever 21d in the part 19e by rotating the timer release lever 19 to the left, causing the timer lock lever 21 to rotate to the right.
Remove the restraint on pin 24f. The timer operating lever 2
4 slides downward by the spring 25 as the pin 24f is no longer restrained by the part 21b, and engages the part 19f with its barb 24c, and the timer release lever 19 is rotated to the left, that is, the pallet lever 14 is rotated with the barb 19a. Hold uninhibited and at the same time Part 2
4e into the operating locus of the pin 16b of the timer sector gear 16. In addition, in the timer release lever 19, the part 21a of the timer lock lever 21 is connected to the pin 24f.
When engaged with the left lock and in this state, the Mage 2
The release state of the self-timer is also maintained because the part 19d is inhibited in 1d. By sliding the timer operating lever 24 downward, the part 24g is positioned below and slightly to the left of the armature 12d of the shutter operating lever 12. The timer sector gear 16 rotates to the right as the pallet lever 14 is released from its restraint, and pushes the part 24e of the timer operating lever 24 with its pin 16b.

When the part 24e of the timer operating lever 24 is pushed, the timer operating lever 24 rotates to the left using the pin 2d as a fulcrum while sliding the pin 24a into the slot 2b.

By turning the timer operating lever 24 to the left, the spring 23 causes the part 21a of the timer lock lever 21 to follow the pin 24f.

However, on the other hand, the timer release lever 24 pushes the part 19f with its barb 24c, which causes the timer release lever 19 to rotate to the left, and pushes the barb 21d with its part 19e, so that the timer lock lever 21 conversely rotates to the right. I am forced to do it. Therefore, the operation of the pallet wheel 14 is not inhibited by turning the timer release lever 19 to the right, and the gear train continues to operate. On the other hand, the timer operating lever 24 moves the part 24g upward and to the right in an arcuate trajectory with the pin 2d as a fulcrum by turning to the left, thereby moving the part 24g toward the release operating lever 12. 12d, operate the lever operation lever 12, first turn on the power switch 13, and then
Rotate lever 9 to the left to perform a shirt release.

Shutter release using this self-timer is performed using pin 16.
This continues while b is engaged with the part 24e, and the power switch 13 is also kept in the on state.

When the pin 16b passes the part 24e, the spring 2
8 or the spring 25, the timer operating lever 24 is anchored to the right with the pin 2d as a fulcrum, and eventually the pin 24a engages with the slot 2a and its right rotation is inhibited. The shirt release operation by the self-timer is performed as described above, but according to the present invention described above, the timer operation lever 24 can perform a sliding operation guided by the linear slots 2a and 24b, and a circular operation. By configuring the self-timer charge operation and the self-timer release operation to operate in two different ways, the rotational movement guided by the arc-shaped slot 2b, the release operation lever 12 is operated by the self-timer. This allows the shirt release to be performed using a self-timer in the same way as when the release operation lever 12 is manually operated through direct discussion.

Therefore, according to the present invention, with an extremely simple structure, only one shirt release operating member, such as a shirt release button, is provided, and the self-timer start and the shirt release release are performed by operating the same button. In addition, even when using the self-timer, such as when using an electric shirt, the power switch 13 is operated in exactly the same way as when manually operating the shirt taller. The battery consumption is exactly the same as when performing , and the effect is that the consumption does not increase in particular. Further, in the present invention, the timer operating lever 24 is not directly engaged with the release operating lever 12, but another member is mounted on the timer operating lever 24, and the timer sector gear 16 operates this member. A shirt release may be performed, and in this case, the self-timer can be reset, that is, the self-timer that has been charged for one day can be operated by operating the charging operation member in the opposite direction to charging. Therefore, for example, when the self-timer is properly charged, it is possible to manually cancel the setting of the self-timer earlier than the operating time of the self-timer has elapsed. This will be explained below using the embodiment shown in FIG.

To avoid duplicating the description of the embodiment shown in FIG. 1, the description of FIG. 2 will be explained. A timer release actuation lever 26 is rotatably attached to the timer actuation lever 124 by a shaft 27. As shown in FIG.

The timer release operating lever 26 has a part 26a that engages with the pin 16b of the timer sector gear 16, a part 26b that engages with the armature 12d of the release operation lever 12 and the part 19g of the timer release lever 19, The shaft 27 is given dextrorotation with the shaft 27 as a fulcrum, and the shaft 27 itself is given a leftward movement habit. The timer sector gear 16 is connected to the pallet lever 14 via a gear train equipped with a known ratchet mechanism (not shown).

The ratchet machine, with the pallet 14 restrained,
When the timer sector gear 16 is turned counterclockwise against the spring 18, that is, when the self-timer is charged, the gear train between this ratchet mechanism and the pallet handle 14 does not operate at all, and the It operates very lightly between the timer sector gear 16, but after this self-timer has been charged, the timer sector gear 16 is rotated to the right in order to reset the self-timer, that is, to release the self-timer charge. In this case, even if the anchor 14 of the aircraft is restrained, the ratchet mechanism will operate and the right turn will be carried out, although there will be some resistance. That is, the ratchet gear used in this ratchet mechanism is not formed in a perfect mirror tooth shape, but in a shape consisting of a gentle slope and a slightly steep slope. Next, the operation will be explained.

FIG. 2 shows a state in which the shirt jacket is charged and the self-timer is at rest, that is, it is not yet charged.

In the illustrated state, charging of the self-timer will first be explained.

The timer sector gear 16 is rotated to the left, and during the initial period of left rotation until the pin 16b engages with the part 124d, the part 26a follows the pin 16b and operates the timer release using the shaft 27 as a fulcrum. -26 turned slightly to the right,
The part 26b moves below the handle 12d of the release operating lever 12.

The timer sector gear 16 further rotates to the left, and its pin 16
When the part 124d is pressed with b to slide the timer operating lever 124 upward and the shaft 27 rises, the timer release operating lever 26, which is supported at two points, the part 26a and the shaft 27, hardly rotates. rises with However, since the part 26a is supported by the semicircular pin 16b, the part 26a is rotated by the rotation of the pin 16b.
Since the gap between the part 124d and the part 124d changes slightly, there is some left rotation, but it is extremely slight. When the pin 16b passes over the part 124d, that is, the timer operating lever 124 stops rising and only the pin 16b becomes actuated, the shaft 27 stops and the timer release operating lever 26 moves to that part. 26a follows the pin 16b and rotates to the right. The self-timer is charged as described above. Next, the operation of the shutter release and self-timer by the release operation in the fully charged state will be explained.

When the timer release lever 12 is raised and the timer release lever 19 is turned to the left, the timer operation lever 124
is unlocked and moves vertically downward, and at the same time, the timer sector gear 16 is rotated to the right by the spring 18, and its pin 16b pushes the part 124e of the timer operating lever 124, which has already slid downward at this time, and the timer sector gear 16 is rotated to the right by the spring 18. The operating lever 124 is moved to the left using the pin 2d as a fulcrum.

As a result, the shaft 27 is moved upward and to the right in an arcuate trajectory with the pin 2d as the fulcrum. The timer release operating lever 26 slides the part 26a onto the pin 16b by the movement of the shaft 27, and moves the part 26b to the lower side of the armature 12d of the release operating lever 12, that is, the operation of the part 26b with the shaft 27 as the fulcrum. Place the maze 12d within the trajectory and approach the maze 12d to the extent that it does not come into contact with it.

Further, by the clockwise rotation of the timer sector gear 16,
The pin 16b presses the part 26 while pushing the part 124e.
Also press a, and this releases the timer release lever 2.
6 to the left about the shaft 27, press the top 12d with the part 26b, turn on the power switch 13, then push the part 9b with the top 12c to rotate the shirt release lever 9 to the left, and release the top 6a by the part 9a. Remove the tie and perform the shirt release.

When the pin 16b passes from the part 124e, the nuclear timer actuating lever 124 is rotated to the right by the spring 28, and this right rotation causes the shaft 27 to be actuated in the opposite direction to the above-described shirt release by the self-timer.

As a result, the timer release operating lever 26 is connected to the pin 16.
b, and move the part 26a to the left while rotating clockwise about the pin 16b as a fulcrum, push the part 26b away from the cover 12d, and move the release operating lever 12 downward by the spring action of the movable contact piece 13a. Slide it. The shirt release operation by the self-timer is performed as described above, but finally, the reset operation of the self-timer will be explained.

In the present invention, the operation means for resetting the self-timer, that is, returning the once charged self-timer to the state before charging, that is, to the stationary state without operating the gear governor, performs an operation opposite to the self-timer charging operation. It can be obtained by

A reset operation is performed by turning the timer sector gear 16 to the right in a state where the above-mentioned timer and self-timer are charged.

When the timer sector gear 16 rotates to the right, it activates the ratchet mechanism provided in the gear train, as explained in 1.
The timer sector gear 16 can be rotated to the right even if the arm 19a is engaged with the armature 19a and its operation is inhibited.

By the way, when the timer sector gear 16 is turned to the left, the pin 124f of the timer operating lever 1241 is rotated to the part 21a.
When the timer sector gear 16 rotates to the right, the pin 1
6b does not engage part 124e, but engages only part 26a, and rotates timer release operating lever 26 to the left.

The shaft 27 of the timer release operating lever 26 moves upward to the right because the timer operating lever 124 does not rotate to the left about the pin 2d, but the pin 124a slides upward along the slot 2a. do not.

Therefore, since the cover 12d of the release operating lever 12 is deviated from the operating locus with the shaft 27 of the part 26b as the fulcrum, the release operating lever 12 is not operated by the left group of the timer release operating lever 26. . The nuclear timer release actuating lever 26 is rotated to the left so that its part 26b is
engages the part 19g, causing the timer release lever 19 to rotate to the left.

As a result, the Mage 19a is removed from Part 14a,
In addition to releasing the restraint on the pallet release lever 14, the part 19e of the timer release lever 19
Press d to turn the timer lock lever 21 to the right and release the pin 124f engaged by the part 21a. The timer operating lever 124 is thereby released from its restraint and slides downward by the spring 25, and its barb 124c pushes the part 19f to hold the timer release lever 19 in a left-handed state.

The shaft 27 is also moved downward, thereby turning the timer release operating lever 26 to the right and returning everything to the state shown. As described above, the self-timer can be charged, released or reset regardless of whether it is before or after charging the self-timer.

According to the present invention, as described above, once the self-timer is charged, the timer sector gear 16 is operated in the direction opposite to the charging operation, as necessary, so that the battery operation lever 12 and the power switch 13 can be operated. Regardless of any of the above, there is an effect that only the self-timer mechanism can be returned to the state before charging.

According to the present invention, regardless of whether the self-timer is used or not, the release operation only requires operating the release operation lever 12, which is extremely easy to operate and has the effect of preventing erroneous operation. can get.

According to the present invention, when the self-timer is used, the shirt release operating lever 12 is inhibited from operating before the power switch I3 is turned on, and the power switch 13 is not activated until the self-timer performs the shirt release operation. Since it is turned on, it has the effect of keeping battery consumption to a minimum.
