However, the position at the end of operation is spatially free for the group of closing blades. Difficult compared to wing group. In order to solve this problem,
No. 84230 (Japanese Utility Model Publication No. 56-34892) has been proposed (particularly, the embodiment shown in FIG. 3). Here, a stop portion 9b formed by standing up and bending the spacing plate 9 is provided at the operation end position of the closing slit forming blade 6a, and the elastic member 10 is attached to the stop portion 9b. According to this method, it is possible to relatively prevent the closing blade group from bouncing.

る。However, the closing slit forming blade 6a does not always drive the shutter driving space between the substrate 1 and the spacing plate 9 horizontally. At that time, the leading end of the closed slit forming blade 6a may move toward the cover plate 30 or the spacing plate 9 in some cases. For this reason, as shown in FIG. 7, there is a possibility that the closing slit forming blade 6a may be interposed between the spacing plate 9 and the elastic member 10 at the end of the operation of the closing blade group. In particular, a problem is likely to occur when the elastic member 10 having poor durability is deformed.

る。The locking portion 9b is provided in the concave portion 9c.
Since the elastic member 10 is provided so as to be in contact with the concave portion 9c, even when the leading end of the closed slit forming blade 6a runs along the spacing plate 9 side, it can abut near the center of the elastic member 10, and The blade 6a is not sandwiched between the plate 9 and the elastic member 10. Also, since a part of the elastic member 10 has entered the hole 30a of the cover plate 30,
Even when the leading edge of the blade 6a travels along the cover plate 30 side, the blade 6a can abut near the center of the elastic member 10 (see FIG. 3). For this reason, the problem of causing an abnormality at the time of charging the shutter is eliminated, and the movement of the shutter can be made smooth.

Not only around the periphery of the elastic member 10, but also because the point where the closed slit forming blade 6 a is provided horizontally and the recess 9 c is provided horizontally, the elastic member 1 is provided.
0 can be provided horizontally long so that the contact area is widened. In other words, a horizontally long concave portion 9c is provided in the travel end area of the closed slit forming blade 6a, and a horizontally long elastic member 10 is provided by the fixing pin 20 there. this,
In another embodiment, the closed slit forming blade 6a and the elastic member 1
Since the contact area with zero increases, the load on the elastic member is reduced, and the speed of deterioration of the elastic member can be reduced.
Further, as shown in FIG. 5, the elastic member 10 may be fixed by the pin 20 using the pin 20 as the stop, instead of using the stopper to bend the spacer shown in FIG. 2. Also, as shown in FIG. 6, the portion of the cover plate 30 facing the elastic member 10 is not formed as a hole as in the first embodiment, but is a protrusion that retreats in the thickness direction from the operating area of the closed blade group. It may be 30b. As shown in FIG. 6, instead of providing the recess 9c in the spacing plate 9, the spacing plate 9 may have a surface 9d in which the entire vicinity of the open blade traveling end area is retreated to the open blade operating region side.
