/):, (2, 4 votes from this lock mode ￥ Photography: I will explain the operation when switching to 2 mode (:).The mode is pressed by the force of the bar spring O and the tension lever Pi 9. The operating member 5 is manually moved to the right together with the mode selection lever 7 against the clockwise rotational force of the tensioning lever 80. The tension lever protrusion 7 that accompanies this movement is caused by the force of the tensioning lever spring 9. The bent part 8 of the strobe tensioning lever 8
Push b to the right. This allows the strobe locking lever 8 to
The locking pawl 8C rotates counterclockwise about the shaft 8a, and the engagement between the locking pawl 8c and the tensioner 10e is released. At this time, due to the upward bias of the pop spring 11, 5
The light device 10 is pushed up and popped up until the light emitting portion 10c along with its legs 10a are exposed at the top of the camera body 1 as shown in FIG. By moving this light) to one side of the container 10, the lock lever 12 is rotated clockwise by the 11 forces of the lock lever spring 16, and the lock claw 12a bites into the click 7b and rotates the lock lever 12 clockwise. At this time, the operating member 5 is placed in the standard photographing mode position, so that manual movement of the operating member 5 is prevented.

Meanwhile, the frame from this lock mode! When the first switch 20 is switched to the il'-+ darkest mode, as will be described later, the motor 15 is not energized, and the movable lens barrel 14 holding the photographing lens 6 is locked with the lock 8. Position I without moving from the current position: Yes.

In addition, as the mode selection L/ /<-7 moves to the right as described above, the barrier switching cam 7d also moves to the right.
: Since the cam 7d moves, the engagement with the rear pin 23a is released. From this, the rear spring 24
Due to the restoring force, the lens aperture 231 rotates clockwise and retreats from above the photographing lens 3 as shown in FIG.
The camera becomes ready for standard shooting.

Next, the state of the camera when switching from standard photography mode to telephoto photography mode will be explained. The operation member 5 and the mode selection lever 7 are manually moved to the right against the force of the mode selection lever spring 6 and the engagement force between the tension lever spring 9 and the lock pawl 1211 and the click 7b. At this time,
The lock pawl 12 & crosses over the inclined surface of the click 7b by the clockwise rotation of the lock lever 12, and bites into the click 7C by the counterclockwise rotation of the lock lever 12 under the force of the lock lever spring 16. match. Exactly, this engagement 2-1i λtsu Jzta11! J.
The mode selection lever 7 is moved fully to the right when the camera is switched from the standard shooting mode to the telephoto shooting mode. As the mode selection mode (-7) moves in the right direction, the first switch 20 is switched as described later, and the motor 15 is energized.The motor 15 rotates forward, and this M1lii driving force is gear 1
6, 17, and 18 to the screw 19, and the rotation of the screw 19 causes the movement of the movable lens barrel 14 and the liquid lens 6 to the camera. It is paid out along the front side of the t-axis. exactly,
When the photographic lens 6 reaches the telephoto (most mode) position, the second switch 21 is switched as described below, and the energization of the motor 15 is stopped (°C), and the photographic lens is positioned (inside). ;71 na 4) 2!ji It becomes possible to take pictures.

On the contrary, we will explain the operation when switching the camera from the telephoto shooting mode shown in Figure 3 (2) to the standard shooting mode C2. Switch the member 5 to the left direction to the standard shooting mode position.As the operating member 5 moves, the mode selection lever 7
The protrusion 7h of the first switch 20 also has the first protrusion 7h. second intercept 2
01.Move to the left with 202 and press switch 2
0 can be used as described below. At this time, motor 1
5 is energized and reversed! ! ! 11 rotations, this rotational force is transferred to gear 1
6.17.18 and the feed screw 19, the movable sharp part 14 is retracted and moved toward the rear of the camera along the optical axis to the border position shown in FIG. 2, and the camera is capable of standard shooting 2. It is used for one input τ.

First, the operation when the camera is switched from the telephoto shooting mode shown in FIG. 3 to the lock mode shown in FIG. 2 will be explained. As shown in FIG. 3, a force is applied to the head of the pop-up device 10 to push it down against the force of the pop-up device 10. Then, the light emitter 10 pops down to the position shown in FIG. At this time, the reset button 10d of the light emitter 10 is released from the lock lever.
12 of the pull-down part 12 c I: bump into it and push it down. 5 This causes the lock lever spring 16 to
The lock lever 12 and its lock pawl 12a rotate in the counterclockwise direction against the bias in the rotational direction, and the engagement between the lock pawl 12a and the click 7C is released. When this engagement is released, the mode selection lever 7 is moved fully toward the left corner together with the operating member 5 due to the operation of the mode selection collar spring 6 and the tension lever spring 9. At this time, the tensioning lever missing portion 7a no longer presses the folding portion 8b, and the restoring force of the tensioning lever by-9 also increases, causing the strobe tensioning lever 8 to rotate clockwise together with its latch 11 and pawl 8c. 1
As a result, the locking pawl 8C and the tensioning member 10e are (6'-coupled) and the device 10 is held in the pop-down state against the force of the pop spring 11.

On the other hand, by moving the protrusion 7 of the mode selection lever 7 to the left in the mode position j≧, the switch 20 is turned on as will be described later. Due to the relationship between this first switch 20 and the third IS2 switch 21, which is switched at the telephoto shooting mode position, the motor 15 is activated as described below. Electricity is applied.

The motor 15 rotates in the reverse direction until it reaches the position shown in FIG. 2 as described above, that is, the standard shooting mode position (lock mode position).
The movable lens barrel 14 is retracted to the rear of the camera together with the photographic lens 3. When this movable lens barrel 14 is retracted, the barrier bin 2
3& comes into contact with the inclined surface of the barrier switching cam 7d, and when the barrier bin 23m is guided along this inclined surface, a counterclockwise force is applied to the lens barrier 23, and the lens barrier 23 is charged while charging the barrier spring 24. Rotate counterclockwise to cover the front surface of the photographic lens 3 and close it. As described above, when the light emitter 10 is popped down and the barrier 23 covers the front surface of the photographic lens 3, the camera is held in a locked state.

Also, although we did not explain the operation of switching from lock mode to telephoto shooting mode, it is obvious from the combined operation of switching from lock mode 'L to standard shooting mode and switching from standard shooting mode to telephoto shooting mode. Therefore, the explanation of this operation will be omitted. Also, when switching from standard shooting mode to lock mode, the movable lens barrel 1
The operation is almost the same as the operation for switching from the telephoto shooting mode to the lock mode, except for the movement in step 4, and the explanation of the operation will be omitted.

However, the mode selection lever 7 is moved to the left together with the barrier switching cam 7d by the mode selection lever spring 6, and at this time,
The barrier bin 23m pushes the barrier switching cam 7d to the left.

With this, the lens barrier 26 is connected to the lens barrier spring 2.
It closes against the force of 4.

Note that when switching from the telephoto shooting mode or the standard shooting mode to the lock mode, the switching is not possible even if the operating member 5 is operated. This is because in standard shooting mode, lock claw 1
2m and the click 7b engage, and these wall portions 12A,
71 collide with each other and lock, so even if you try to manually move the operating member 5 to the left by applying force, the operating member 5 and the mode selection lever 7 will not move to the left lock mode position. It is. Therefore, these switchings are performed only by pushing the light emitter 10 as described above.

Although the finder 4 has not been explained in the above explanation, the index 7e is also positioned according to the positioning of the operating member 5 to each mode position, and the mode is clearly indicated according to the state of the selected mode. In order to do this, the index 7e points to one of the L, W, and T symbol marks on the frame mask.

Therefore, when cutting or moving the operating member 5, please visually check which mode it is in through the finder 4 and perform the operation 5.
All you have to do is cut il 5.
