Abstract

PURPOSE:To obtain a camera shutter with two exposure characteristics different considerably each other in which opening is made by giving a knock to a shutter blind driving member, by performing the knock by a rotating member that can make normal and reverse motion different in kinematic characteristic. CONSTITUTION:Shutter blinds 3, 4 have two exposure opening, large and small, 3b, 3c, 4b, 4c, respectively, and the aperture 9 is opened by turning of an interlocking member. When a motor M rotates reversely, a rotary disk 12 and a driving member 13 rotate in a body clockwise. When a locking member locks the disk 12, the driving member 13 release the locking by a cam after charging a spring 14, and the driving member makes quick rotation and gives a knock to a pin 5. Thus, high speed exposure by small openings 3c, 4c is performed. When the motor M rotates normally, the pin 5 is knocked from reverse direction at steady rotation speed of the driving member, and low speed exposure by large openings 3b, 4b is performed.

BACKGROUND ART Conventionally, in a so-called single-blade shutter in which the shutter is opened and closed by kicking a single shutter blade that is biased so as to hit a stopper against the bias, a regulating part assembly is provided in the movement path of the shutter blade. It is known to obtain two shutter speeds by moving the shutter forward and backward. In such a device, since the shutter speed is only two speeds, a film with a wide latitude range is used, and the brightness of the subject is compensated for by the latitude of the film.

Therefore, if the subject has medium brightness and you shoot at either high or low speed, and the latitude of the film compensates for overexposure or underexposure, then the difference between the two speeds should be as large as possible or appropriate. This is preferable because the range of subject brightness that can be exposed and photographed becomes wider.

However, in the above-mentioned shutter device, the difference between the two shutter speeds cannot be too large, so the brightness range of the subject that can be photographed is narrow, and proper exposure cannot be obtained in the case of high or low brightness. .

Further, in the above-described embodiment, a part of the shutter is configured such that two shutter blades slide in opposite directions, and depending on the sliding direction, exposure is performed with large apertures overlapping each other or small apertures overlapping each other. However, this is not limited to
For example, exposure may be performed by the driving member driving a single shutter blade that is spring-biased to a neutral position where the shank is closed. In this case, exposure is performed by moving the shutter blades away from the exposure aperture of the camera in different directions depending on the direction of rotation of the rotary disk.

Effects As described above, in the present invention, the rotary member is rotated once, the shutter member is driven based on this rotation, and when the rotary member rotates in the forward direction, charging is performed based on this rotation. When the combined force of the rotational force of the driven spring and the rotating member drives the shutter member, and the rotating member rotates in the opposite direction, the drive spring is not charged and the rotating member does not rotate. Since the shutter member is driven only by force, it is possible to obtain a high-speed shutter and a low-speed shutter with a large speed difference by simply changing the direction of rotation of the rotating member, and a simple two-speed shutter that can cover a wide subject brightness range. A shutter device can be obtained.

In addition, in the present invention, the member for closing the plate of the shutter member can be arranged relatively freely around the rotating member as necessary, and can be used for various types of shutters such as single-blade and double-blade shutters. It is possible to obtain a dual-type simple shutter device which is free from errors caused by the rotation of the rotating member and the shutter drive member, and which is more accurate than conventional devices.
