- the size can be reduced by adopting such a structure in which the sectors are divided and the outer sector is oscillated by the inner sector.
- the peristaltic ring 3 is kept stationary by the worm gear 9W. Therefore, in the lens barrier device 1, the situation in which the sectors 11 to 14 are opened in the closed state due to the movement of the swing ring 3 unintentionally, and the situation in which the sector is closed in the opened state are prevented. Further, since the swing ring 3 is moved reliably by the worm gear 9W, the swing operation of the sectors 11 to 14 is stabilized.

- the amount of engagement between the worm gear 9W and the teeth 37 is designed so that the worm gear 9W can be rotated further in the state of closing shown in FIG. Therefore, the worm gear 9W can be rotated one more step from the state shown in FIG.
- the worm gear 9W first regulates (locks) the movement of the rocking ring 3 as described above.
- the ends of the openings 33 and 34 of the swing ring 3 are in contact with the protrusions 11PR and 12PR, the movement of the inner sectors 11 and 12 is restricted.

- FIG. 8 is a block diagram of the lens barrier device 1.
- the present lens barrier device 1 includes a control unit 57 that monitors ON and OFF of SW1 and SW2.
- the control unit 57 is configured, for example, centering on a CPU, and a memory unit 58 is connected.
- the memory unit 58 includes a ROM for storing a program related to the driving of the apparatus 1 and a RAM for providing an area for arithmetic processing.
- the control unit 57 reads a predetermined program from the memory unit 58, and controls the motor 6 for driving the worm gear 9W through the drive circuit 59.
- FIG. 8 shows an example of a configuration in which the present lens barrier device 1 includes the control unit 57 and the memory unit 58.
- the control unit 57, the memory unit 58, etc. shown here are realized by the lens barrel 4 to which the present lens barrier device 1 is connected or the control device built in the camera (not shown) side provided with the lens barrel 4. A configuration may be adopted.
- FIG. 9 shows the process until the sectors 11 to 14 of the present lens barrier device 1 are in the open state (FIG. 4) and the force is also in the closed state (FIG. 1), and further the lock state (FIG. 7) is formed.
- It is a flowchart showing an example. The processing of this flowchart is executed by the control unit 57. This flowchart is activated, for example, by turning on the lens barrier device 1 or a no-close switch (not shown) provided on the camera side.
- the control unit 57 confirms that the SW1 (51 in FIG. 4) is off (S10). This flow chart is executed when the open state force sector shown in FIG. 4 is closed. It is normal that the free end 51 f is separated from the contact piece 56 of the switch piece 55 by the projection 35 and is off. Therefore, when the off state can not be confirmed in step 10, the control unit 57 determines that there is an abnormality and stops the processing of this flowchart.
- controller 57 When controller 57 confirms in step 10 that SW 1 is off, motor 57 is turned off. Constant step (for example, 3 steps) Driving in the closing direction (Sl l), it is checked whether SW1 has turned on (S12). If the switch SWl is not turned on only once this step 12 is performed, the control unit 57 adds 1 to the memory A to drive the motor 6 again (S16). If this process is repeated, for example, three times and the SW 1 is not turned on, it is judged that there is an abnormality and the process is stopped (S 17).
- control unit 57 drives motor 6 in the closing direction until SW2 (52 in FIG. 1) is turned off (S13, S14). ). This process forms the closed state of FIG. Then, after that, the control unit 57 drives the predetermined stepping motor 6 set in advance in the closing direction (S15). By the last motor drive, the lock state shown in FIG. 7 is formed, and the processing according to this flowchart is ended.
- the driving force is transmitted from the motor 6 in the swing ring 3 ⁇ -direction with the worm gear 9W interposed. Since the worm gear 9W and the teeth 37 of the rocking ring 3 are engaged, and the rocking ring 3 is rotated by the rotation of the worm gear 9W, the sectors 11 to 14 can be rocked reliably. In this structure, the worm gear 9 W reliably regulates the movement of the rocking ring 3 after stopping. As a result, sectors 11-14 can be maintained open and closed.
- the present lens barrier device may be realized with a removable configuration with respect to the lens barrel 4 or with a structure integrally set on the front surface of the lens barrel 4.
- the openings 33 and 34 provided in the rocking ring 3 are openings 33 ′ and 34 ′ which are longer in the rocking direction of the protrusions 11PR and 12PR, and the locked state of FIG.
- the protrusions 11PR, 12PR may not be in contact with the openings 33, 34 'when the That is, by setting the openings 33, 34 'to be longer than the openings 33, 34, there is room for the projection parts 11PR, 12PR to move even during transition to the closed state or in the locked state. , 12 movement in the opening direction is possible. In this way, in the locked state, since the rocking ring 3 is pivoted from the closed state of FIG.
- the biasing force of the coil panels 21 and 22 is further increased and it is difficult to open even if an external force is applied. Also, by any chance during the transition to the closed state, a foreign object is sandwiched between sectors 11 and 12 Also, since the protrusions 11PR and 12PR are not in contact with the openings 33 and 34, movement of the sectors 11 and 12 in the opening direction can be permitted against the biasing force of the coil panels 21 and 22. For this reason, even when foreign objects are caught in the closed state or in the locked state, the sectors 11 and 12 can move relative to the swing ring 3 in the opening direction, so it is impossible for the swing ring 3 or worm gear 9W. There is no force applied, and there is no risk of damage to gears and the like.
