- the first urging member 47b urges the iron piece 46b in the axial direction AD1 of the shaft portion 45b.
- Play is provided between the iron piece 46b and the facing surface 42b1. That is, by pressing the iron piece 46b in the axial direction AD2 against the urging force of the first urging member 47b, the iron piece 46b can move until the back surface of the iron piece 46b comes into contact with the opposing surface 42b1. At this time, the shaft portion 45b also moves in the axial direction AD2 together with the iron piece 46b.
- the axial direction AD2 is opposite to the axial direction AD1.
- the iron piece 46b is supported in the axial direction AD1, AD2 so as to be able to stroke within a predetermined range and is urged in the axial direction AD1.
- the rear curtain drive lever 40B can continue to rotate further by the stroke possible range of the iron piece 46b.
- the rear curtain drive lever 40B is set so as to rotate excessively even if the iron piece 46b contacts the iron core 73b. The reason for this is to absorb the variation in the positional accuracy of the iron piece 46b and the iron core 73b that may occur for each product, and to rotate the rear curtain drive lever 40B until the iron piece 46b is securely in contact with the iron core 73b.
- the iron piece 46b has a central part 46b1 in which a hole into which the fitting part 45b5 is fitted is formed, and end parts 46b2 and 46b3 extending in the opposite directions from the central part 46b1.
- the side surface of the central portion 46b1 When viewed from the front of the iron piece 46b, the side surface of the central portion 46b1 has an arc shape.
- the width of the central portion 46b1 is larger than the widths of the end portions 46b2 and 46b3.
- the guide portion 44b has a recess 44b1 for escaping the arc-shaped side surface of the central portion 46b1.
- the guide portion 43b is also formed with a cutout portion 43b1 for releasing the arc-shaped side surface of the central portion 46b1.
- the second urging member 49b is interposed between the guide portion 43b and the iron piece 46b. As shown in FIG. 8, the base portion 49b1 of the second urging member 49b is partially in contact with the side surface of the central portion 46b1. Accordingly, the base portion 49b1 is curved along the side surface of the central portion 46b1. By deforming the second urging member 49b in this way, the iron piece 46b is urged in the radial direction RD1.
- the radial direction RD1 is a direction that intersects the axial directions AD1 and AD2, and is a direction that is substantially orthogonal. In other words, the radial direction RD1 is a direction toward the rotation fulcrum side of the trailing curtain drive lever 40B.
- the iron piece 46b is supported so as to be movable in a radial direction RD1 and a radial direction RD2 opposite to the radial direction RD1.
- the radial directions RD1 and RD2 are directions included in a virtual plane in which the rear curtain drive lever 40B rotates.
- the iron piece 46b When the iron piece 46b is urged in the radial direction RD1 by the second urging member 49b, the iron piece 46b is pressed against the guide portion 44b. Specifically, the side surfaces of the end portions 46b2 and 46b3 are in contact with the guide portion 44b, and the side surface of the central portion 46b1 is not in contact with the guide portion 44b.
- the through hole 42b5 of the support portion 42b through which the body portion 45b3 of the shaft portion 45b passes has a shape slightly extending in the radial directions RD1 and RD2. Therefore, the body 45b3 has some play in the radial directions RD1 and RD2 in the through hole 42b5. Thereby, the iron piece 46b can be moved within a predetermined range in the radial directions RD1 and RD2. As a result, the posture of the body 45b3 may change in the through hole 42b5, and the body 45b3 may be inclined with respect to the axial direction of the through hole 42b5. Thereby, the iron piece 46b can move in the direction SD so as to swing.
- the direction SD is a direction included in a virtual plane in which the trailing curtain drive lever 40B rotates.
- the reason why the iron piece 46b is supported so as to be movable in the radial directions RD1, RD2 and SD is as follows.
- the rear curtain drive lever 40B rotates with a predetermined position as a fulcrum. For this reason, the iron piece 46b moves on an arc-shaped locus and contacts the iron core 73b.
- the iron piece 46b is supported so as not to move in the radial directions RD1, RD2 and SD, depending on the positional accuracy of the iron piece 46b and the iron core 73b, when the iron piece 46b comes into contact with the iron core 73b, both contact surfaces May not be parallel. Thereby, there is a possibility that the adsorbing force between the iron piece 46b and the iron core 73b cannot be secured without the two being in close contact with each other.
- the iron piece 46b can be moved so that when the iron piece 46b comes into contact with the iron core 73b, the abutting surfaces of both of them come into close contact. It becomes. Thereby, both can be stuck without being influenced by the position accuracy of the iron piece 46b and the iron core 73b.
- the posture of the iron piece 46b may not be maintained constant. For example, this is a case where the trailing curtain drive lever 40B is reciprocated in a short time. If the posture of the iron piece 46b cannot be maintained constant, the posture of the iron piece 46b when contacting the iron core 73b cannot be maintained constant, so that there is a possibility that variations in the positional relationship between the two when contacting.
- the iron piece 46b is not only urged in the axial direction AD1, but also in the radial direction RD1 intersecting the axial direction AD1 so as to be pressed against the guide portion 44b. Be energized. Thereby, the iron piece 46b is hold
- the posture of the iron piece 46b when contacting the iron core 73b can be maintained substantially constant. Accordingly, the positional relationship between the iron core 73b and the iron piece 46b can be maintained substantially constant. Accordingly, the timing when the energization to the electromagnet 70B is cut off and the iron piece 46b is separated from the electromagnet 70B can be maintained constant.
- the second urging member 49b is located between the shaft 45b and the opening 11 as shown in FIGS. Accordingly, even if the guide portions 43b and 44b and the through hole 42b5 are scraped to generate dust, it is possible to prevent the dust from being scattered to the opening 11 side due to the reciprocating motion of the rear curtain drive lever 40B. Thereby, the deterioration of the image quality is also prevented.
- the rear curtain drive lever 40B can be downsized. Further, since the iron piece 46b is pressed against the guide portion 44b, it is prevented from rotating around the axis of the shaft portion 45b.
- FIG. 9 shows a state where the iron piece 46b has moved in the radial direction RD2, which is the direction opposite to the biasing direction of the second biasing member 49b.
- the force in the radial direction RD2 may act on the iron piece 46b.
- the side surfaces of the end portions 46b2 and 46b3 are separated from the guide portion 44b, and the iron piece 46b moves so that the central portion 46b1 further presses the base portion 49b1 outward.
- the base portion 49b1 is further curved by the force in the radial direction RD2 acting on the iron piece 46b and protrudes outward from the notch portion 43b1. In this manner, the iron piece 46b is allowed to move in the radial direction RD2.
- the blade is made of a synthetic resin having a thin thickness
- the blade may be made of a thin metal.
- a plate-like spring has been described as an example of the second urging member
- a coil-like spring may be used.
- the iron piece 46b may be biased in the radial direction RD2.
- the focal plane shutter of this embodiment can be used for optical devices such as still cameras and digital cameras.
