JPS5979232A - Flash device built-in type caseless camera - Google Patents

Abstract

PURPOSE:To reduce damage in case when a flash is not used, by constituting so that at least one of a movement of a camera protecting member to a shielding position from an opening position and a movement of a light emitting part is interlocked with the other. CONSTITUTION:When a flash device is not used, a light emitting part 5 is in a containing position and a support 6 is detained by a key 8 and a notched part 6a. An electromagnet 9 attracts the key 8 by a low luminance signal from an exposure meter, the support 6 rises by a spring 10 and the light emitting part 5 rises. When a pin 6b of the support 6 is engaged to an inclined face 1b of a substrate 1a of the reverse side of a slide cover 1 and the cover 1 is moved to the left shielding position, the inclined face 1b moves the support 6 and the light emitting part 5 to the lower containing position through the pin 6b. In this case, there are three states (a) a containing movement of the light emitting part is interlocked with a movement of a shielding member, (b) a shielding movement is interlocked with the containing movement, or (c) the shielding movement and the containing movement are interlocked with each other.

Description

[Detailed Description of the Invention] The present invention relates to a caseless camera with a built-in flash device.Currently, 1/2-inch shutter cameras are capable of taking pictures at night or in dark places, and are also compact. - Cameras with built-in flash devices are popular because of the nature of the situation. In this case 1
The light emitting part is stored in the camera body so that it does not get in the way when not in use, but when in use it is best to place it as far away from the lens as possible to make the photographer and the subject aware of its use. Since it is easy to take pictures, it is preferable to use a pop-up type, where the light emitting part protrudes from the camera body.

On the other hand, in order to make the camera more compact, caseless cameras are also on sale, in which a sturdy protective member (+/lens cover) is attached to the camera body in a sliding or door-type manner, instead of using a camera case.

Therefore, after taking a photo, there are two operations that must be performed: retracting the light emitting section and returning the lens cover.

Therefore, general users are demanding a caseless camera with a built-in flash device that is easier to operate.

A camera that meets this demand is already on the market, but this camera has a flip-up light emitting section ()IJ knob up).
The light emitting part protrudes because it is built inside the cover.
The storage operation is completely linked to the opening and closing operation of the cover.

However, scenes that require flash photography only account for a small percentage of the total number of shots taken.

There is no need to stick out the light emitting part every time you take a picture. On the contrary, the problem is that the light emitting part protrudes even when there is anxiety, increasing the chance of damage. Especially when carrying around the camera with the cover flipped up, there is a risk of damage (somewhat more).Therefore, it is not a good idea to completely link the light emitting part and the protective member.

For this reason, one aspect of the present invention is to use a viewfinder when using a camera.
A protection member that can be moved between a position for shielding the photographic lens, etc. and an open position for retracting from the photographic lens, etc. when in use, and a protruding position when the flash device is in use and a storage position when not in use. In a caseless camera with a built-in flash device that can be moved between the two positions, the protective member is retracted from the blocking position to the open position, and the light emitting portion is retracted to the storage position. The protection member is shielded from the open position without interlocking with the protruding movement of the protruding position -\.
To provide a camera characterized in that at least one of the movement of the light emitting part to the position where it is blocked and the movement of the protruding position of the light emitting part and the movement of the storage position and the storage position of the light emitting part is linked to the other. .

In other words, in the present invention, (a) should the shielding movement be linked to the storage movement, or (b) should the storage movement be linked to the blocking movement. There are any three mW of movement that can be used in conjunction with each other.

Next, the present invention will be specifically explained with reference to the drawings and practical examples.

Embodiment In this example, the storage movement of the light emitting part from the protrusion position 1 to the storage position is linked to the movement of the protective member (here, the slide cover) from the open position to the shielding position. This is an example of this.

Fig. 1 is a schematic perspective view of the camera according to this practical example, in which the slide cover (]) is in the open position, and when the camera is not in use, the user faces the drawing to the left. Move it toward the camera and block the photographing lens (2), finder window (3) and EE light receiving window (4).

The two-dot chain line (51&';!) is the light emitting part of the flash device in a disengaged state. In Figure 1, the light emitting part is in the retracted position. Figure 2 shows the core part of the camera in the wooden embodiment ( This is an explanatory diagram showing the spine, and the light emitting part (5) is in a state where the camera body is popped up on the ellipse.The light emitting part (5) is moved between the pop-up position and the storage position by the support (6). The pillar (6) has guide pins (7a), (7
b) Guided by j, move the light emitting part (5) up and down.

When the flash device is not in use, the light emitting part (5) is in the retracted position (lower position), and the column (6) is locked in the notch (6a) by the key (8). It's okay. And when the camera receives a low brightness signal from the light meter when using it.

Based on this signal, a plow use signal is sent to the electromagnet (9).

The electromagnet (9) works to attract the key (8), and the key (8) rotates clockwise. As a result, the locking bt of the strut (6)
yH chews, the pillar (6) rises up due to the force of the spring (10).

Part 1. 7-1c, the light emitting part 1 (5) moves from the storage position to the pop-up position (2nd position).
) may be released by an electrical or mechanical signal based on the user's judgment, instead of using the (1, σ from the exposure meter) signal.

In Fig. 2, the slide cover (]) is indicated by a two-dot chain line C, and when the camera is used, it is in the first position, that is, in the present invention, in the 35 open position. On the other hand, a pin (6b) stands on the support (6), and this pin (6b) is in contact with the slope (Jb) of the plate (la) on the back side of the slide cover (1). be. Therefore, after using the camera, when the user moves the slide cover (]) to the left toward the drawing, that is, to the blocking position in the present invention, the pin (6b) is moved by the slope (]a). The downward direction is pushed down to the twelfth position, and the support column (6) is also pushed downward, and at the same time, the light emitting part (5) is moved from the pop-up state to the stowed position. Ru.

In addition, according to the groove structure of this embodiment, the slide cover is
When it is in the correct position, there is an advantage that the light emitting part will not pop up even if you accidentally send a signal to use the flash device.

Example This actual flame example shows the protection member from the open position to the closed position.
The shielding position and the movement of the light emitting part from the protruding position to the retracted position and retracted position are interlocked with each other. This is an explanatory diagram showing the construction, and here the pillars that move the light emitting part up and down (same as (6) in Figure 2), etc. are omitted.
Only the pin (6b) standing on the support is shown.

FIG. 3 shows a state in which the slide cover is in the shielding position and the five light emitting parts are in the storage position.

When the flash device is not in use, the pin (6b) is in the position shown in the drawing, and even if the slide cover moves back and forth between the closed position and the open position, the pin (6b) remains in the hx cam groove (IC). The pin (6b) itself does not move at all, only moving relatively within the horizontal groove.

On the other hand, when using the flash device, for example, as in Example J, when the column (6) is released, the column (6) rises due to the biasing force of the spring, and the column (6) rises with t'+. As a result, the pin (6b) also rises in the vertical groove of the cam groove (1c), and eventually collides with one end (llb) of the lever (1), but the lever (11) is rotated counterclockwise by the spring (12). Because it's only one body that is biased in the direction.

The lever (11) is rotated clockwise against the biasing force of the pin (6L) and the lever (11) is moved away from the cam groove, and the pin (6b) rises to the α position shown in Figure 2 and stops. As a result, the light emitting unit fixed on the support moves from the stored position 1σ to the pop-up position 1, and the photon is ready for shooting.

After taking a picture, when the user pushes the light emitting part downward to retract it, the pin (6b) is pushed into one end of the lever (ll).
b) to try to rotate counterclockwise by pushing, but the other end (lla) of the lever (1) is in contact with the wall (1e), which prevents the lever (H) from rotating. Therefore, the pin (6L+) slides down in the diagonal groove of the cam groove (1C), and as a result, the back plate of the slide cover (
+a) to the left when facing the drawing, and place the pin (6b) at the β position in the drawing. In this state, the first light emitting section returns to the storage position, and the slide cover returns to the blocking position.

Contrary to the above, when the slide cover and back plate (1a) are moved to the left in the drawing, that is, to the closed position, the pin (6b) moves from the α position to the β position. Result 3
The light emitting part returns to the pop-up position or the stowed position as the column moves.

Therefore, in the embodiment of this actual gun example, when either the slide cover or the light emitting section is returned to its original position, the other one is also returned to its original position in conjunction with t'l. Further, when the slide cover is in the shielding position, the light emitting section will not pop up even if a flash device use signal is sent by mistake.

In Examples 1 and 2 above, the case where the protruding position is the pop-up position has been explained, but the position fθ that protrudes from the camera body in the horizontal direction is also equivalent to the protruding position in the present invention. .

As mentioned above, according to the present invention, the light emitting part does not protrude when the protective member is opened, so there is less chance of damage when the flash is not used, and the VK used can be removed from the protective member. Further, by returning the t1 light emitting part to its original state and performing the t-operation, the other part is also returned to its original state, making the camera easier to handle.

In particular, caseless cameras that automatically measure the brightness of the subject and automatically project the light emitting part when the brightness is low are placed in a charging state after the light emitting part is in the protruding state. If you forget to retract the light-emitting part and leave it in the protruding state for a long time, the battery will wear out quickly because the charged electricity will be lost due to natural discharge.

In contrast, with the camera of the present invention, there is less risk of forgetting the light emitting part and leaving it protruding, so the present invention is particularly useful for the above-mentioned type of camera.
