Abstract

PROBLEM TO BE SOLVED: To prevent a barrier with which a photographing lens on the front surface of a camera is covered from being projected from the front surface or the side surface of the camera when the barrier is opened/closed. SOLUTION: The barrier with which the photographing lens in a camera body 2 is covered is constituted of a large barrier 3 and a small barrier 4 journaled (5) on one side surface part of the barrier 3. The barrier 4 is energized by a spring 6 in an erect direction, and the barrier 3 is supported on the inner surface of a front cover 1 and meshed and coupled with the rack of a barrier holding lever 12 energized by a spring 15 inward. When the barriers 3 and 4 are closed, they advance in an aperture part formed on the front cover 1 provided on the front surface of the camera body 2, and when the barriers are opened, the barrier 4 is pressed inward, set as a finger-hold and allowed to slide laterally, so that the barrier 3 is somewhat moved in a vertical direction at its taper part 3a at the end, and then slides along the front surface of the cover 1.

2. Description of the Related Art As a conventional barrier, there is known a barrier that covers all so-called optical members on the front surface of a camera. But,
The barrier was provided with a groove for sliding the barrier in the thickness direction from the front cover of the camera and sliding. Also, when the camera becomes smaller, one person travels laterally from the side of the camera with one barrier open. Furthermore, as shown in Japanese Utility Model Publication No. 61-2983, there are some barrier units that are traveling on the whole from the front of the camera. This barrier is composed of two large and small barriers, and the small barrier does not slide and is simply retracted.

By the way, in the above-mentioned conventional example, since the front cover portion protrudes from the front cover in the thickness direction, there is a drawback that the camera is inadvertently moved when it is housed in the case. Further, in the case where the slide groove for the barrier is provided on the front cover, dust is accumulated in this groove, and there is a drawback that the appearance is unsightly. Also, when opening one barrier to the front of the camera grip side, the barrier protrudes toward the grip side, making it difficult to hold the camera and leaving a gap in appearance, which is unsightly, and there are restrictions on the layout of the viewfinder and AF window. There was a drawback that occurred.

The operation of this embodiment having the above configuration will be described.
First, when the camera is not used, the large barrier 3 and the small barrier 4 are completely embedded in the opening 1a of the front cover 1 via the barrier holding lever 12 by the biasing force of the spring 15, as shown in FIGS. There is no protruding part. As a result, the zoom lens barrel 10, the AF window 22, and the finder window 23 are completely covered with the barriers 3 and 4. In addition, if the flash device is of a known rewritable system, the light emitting window is not completely visible, so that no optical windows are exposed on the front surface of the camera. Therefore, it is protected without dust, scratches, fingerprints, etc.

Next, in order to open the barrier for use by the camera, the small barrier 4 is pushed toward the inside of the camera as shown in FIG. Then, the small barrier 4 tilts inward against the urging force of the spring 6, and the slip stopper 4a catches the finger. Therefore, when the barriers 3 and 4 are slid in the opening direction (left direction in the drawing), the front cover 1 The taper 1b of the opening 1a and the taper portion 3a of the end surface of the large barrier 3 come into contact with each other, and the large barrier 3 rides on the upper surface of the front cover 1. At this time, the barrier holding lever 12 rotates counterclockwise against the biasing force of the spring 15 and moves to the subject side (front). When the large barrier 3 slides further to the left, it stops with a stopper (not shown). When the finger is released from the small barrier 4 in this state, the small barrier 4 is rotated counterclockwise by the urging force of the spring 6 and stands upright as shown in FIG. Then, when the small barrier 4 is completely upright, the protrusion 4b turns on the main switch 24.

When the main switch 24 is turned on, the zoom lens barrel 10 is extended to the front of the camera by the operation of a motor (not shown). However, since the small barrier 4 stands upright along the side surface of the zoom lens barrel 10, it does not hit the zoom lens barrel 10. Then, when this barrier open state is viewed from the front, it becomes as shown in FIG.

Next, in order to close the barrier, the large barrier 3 is slid in the closing direction with the anti-slip portion 3d of the large barrier 3 in the state shown in FIG. 5, and the small barrier 4 is also interlocked in the closing direction (to the right). The main switch 24 is turned off. As a result, the zoom lens barrel 10 is retracted into the fixed barrel 9 by a motor (not shown). Further, when the large barrier 3 is slid to the right, the projecting piece 4b of the small barrier 4 engages with the step cam 11 as shown in FIG. 6, and the small barrier 4 rotates clockwise. The large barrier 3 moves further to the right,
When moved to the upper surface of the opening 1 a of the front cover 1, the barrier holding lever 12 is rotated clockwise by the spring 15. Therefore, the large barrier 3 enters into the opening 1 a of the front cover 1. Since the protruding portion 4b of the small barrier 4 is engaged with the step cam 11, the small barrier 4 rotates clockwise in conjunction with the movement of the large barrier 3, and similarly the opening 1 of the front cover 1 is opened.
It enters into a and becomes the closed state of FIG.

As described above, the present invention as set forth in claim 1 is a barrier capable of covering a taking lens or the like on the front surface of a camera, the barrier being slidable relative to the camera body in parallel to the film surface. At the same time, it is possible to move in the direction perpendicular to the film surface, the barrier enters the inside of the camera when the barrier is closed to reduce the amount of protrusion, and when the barrier is opened, it retreats outside the camera,
When the barrier of the camera is closed, the protrusion completely disappears, it is suitable for carrying, it is hard to break due to unintentional force such as shock, and the groove for sliding the barrier is unnecessary, so dust etc. do not collect. According to the present invention as set forth in claim 2, the barrier is large or small.
The large barrier is movable in parallel with the film surface, and the small barrier is rotatably attached to the large barrier.
When the barriers are closed, the two barriers are arranged side by side to cover the front surface of the camera, when the barriers are opened, the large barrier slides, and the small barrier rotates so as to erect substantially along the lens barrel so that it can be withdrawn. The degree of freedom in the arrangement of the taking lens, viewfinder window, and AF window is increased, the barrier does not travel to the grip side, and the movement of the lens barrel is not hindered.
