[0002]

2. Description of the Related Art Conventionally, as a mechanism for popping up a strobe light emitting portion, Japanese Utility Model Publication No. 5-31 has been proposed.
No. 633 discloses an access mechanism for a built-in strobe light emitting unit in a single-lens reflex camera. 13 and 14
FIG. 5 is a central vertical cross-sectional view of a main part of the single-lens reflex camera to which the above-mentioned access mechanism is applied in a vertical plane including a photographing optical axis, showing a strobe retracted state and an ascended state.

[0003] In the above-mentioned strobe light emitting / retracting mechanism, when the strobe housing 114 accommodating the strobe light emitting unit is stored in the strobe housing storage chamber 116 of the camera housing 112, as shown in FIG. Stop lever 13
8 hook 140 is engaged with the pin 120 of the strobe housing 114 to prevent the strobe housing 114 from jumping out due to the urging force of the extension spring 128.

Then, when the user pushes down the operation projection 158 downward, the slider 154 and the pin 156 are pushed down integrally, and the connecting member 146 rotates clockwise. Due to the rotation, the locking lever 138 rotates counterclockwise, and the engagement between the hook 140 and the pin 120 is released. Then, the leg lever 118 rotates counterclockwise due to the urging force of the tension spring 128, and the strobe housing 114 projects obliquely upward and forward from the storage chamber 116, and the strobe is raised as shown in FIG. Further, when the strobe housing 114 is stored, if the front surface of the strobe housing 114 is pushed in the direction of the arrow, the strobe storage state shown in FIG. 13 is obtained.

In the above-mentioned access mechanism, the strobe housing 1
14, a portion combining the leg lever 118, the tension spring 128, the locking lever 138, and the like corresponds to a pop-up mechanism, a portion combining the operation protrusion 158 and the slider 154 corresponds to a pop-up operation member, and a connecting member 146 and a pin. It is considered that a portion in which the 148 and the spring 152 are connected is connected to the pop-up operating member and the pop-up mechanism, and corresponds to a pop-up interlocking member that transmits the movement of the pop-up operating member to the pop-up mechanism.

[0006]

However, in the type of the access mechanism of the built-in strobe light emitting unit disclosed in Japanese Utility Model Publication No. 5-31633, the movement of the pop-up operation member is surely controlled by the pop-up mechanism. In order to make the strobe housing pop up smoothly by transmitting the light, it is necessary to reduce backlash, falling, and bending of the pop-up interlocking member. Therefore, the shape of the pop-up interlocking member tends to be large.

On the other hand, miniaturization of the entire camera is an indispensable requirement, and in order to achieve this, it is natural that miniaturization of the pop-up interlocking member is also indispensable. Shorten the length of the path to be transmitted to the pop-up mechanism,
It becomes necessary to dispose the interlocking member in a portion where space is available.

Therefore, the pop-up operating member must be arranged in the vicinity of the pop-up mechanism, or an arrangement in which the operability of the operating member is sacrificed must be adopted. As a result, the degree of freedom in designing the arrangement of the pop-up operating member is reduced. There has been a problem that it is difficult to secure good operability of the pop-up operation member due to the narrowing.

And a take-up spool 16 rotatably supported by a support shaft 17 fixed to a base plate 18. In addition,
The base plate 18 is fixed to the camera housing 5 by screws (not shown).

The take-up spool 16 is formed with a protruding arm 16a and a V-shaped groove, and the other end 13b of the narrow cable 13 is fixed on the V-shaped groove as described above. Further, the pop-up operation member 20 is formed with a leg portion 20a that comes into contact with the arm portion 16a of the take-up spool 16.

When the narrow cable 13 is routed between the locking slider 11 and the take-up spool 16 as described above, and the leg 20a is in contact with the arm 16a, the narrow cable 13 is connected to the narrow cable 13. The tension of the biasing spring 12 is acting via the locking slider, and is in a tension state. Therefore, when the pop-up operation member 20 is pressed in the direction of arrow D0, the leg portion 20a presses the arm portion 16a to drive the take-up spool 16 to rotate. Then, the locking of the flash housing claw portion 6b by the hook 11a is released.

The narrow cable 13 has both ends 13a, 13a.
