Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This idea opens and closes the front of the photographic lens by sliding it on the front of the camera body. This invention relates to a camera provided with a lens barrier.

0002

[Conventional technology]

To ensure that you can firmly hold the camera body and support it stably when shooting. , a so-called grip part is provided that protrudes from the camera body to place the fingers of the hand. If the camera is equipped with a lens barrier, the grip part will be attached to the lens barrier. is formed.

0003

[Problem that the idea aims to solve]

In conventional cameras that have a grip part formed on the lens barrier, the lens barrier The grip part always protrudes from the lens barrier regardless of whether the camera is opened or closed.

0004 However, the protruding grip part is unnecessary when the camera is not in use; When you put the product in your pocket or handbag, the grip may get in the way. This impaired the portability of the camera.

[0005] This invention eliminates such conventional drawbacks, and when the lens barrier is closed, Providing a camera that is highly portable and easy to hold when the lens barrier is opened aimed to.

[0006]

[Means to solve the problem]

To achieve the above purpose, the camera of the present invention opens and closes the front of the photographic lens. At least a lens barrier that can be slid freely on the front of the camera body. A part of the lens barrier is formed of a flexible plate-like member, and the lens barrier is closed. In this case, the lens barrier does not protrude from the camera body, and the lens barrier does not protrude from the camera body. In the open state, the flexible portion of the lens barrier deforms and the camera body It is characterized by being made to protrude from the inside.

[0007] In addition, the back side of the above lens barrier should be convex in the shape of a rack or timing belt. It may be formed into a concave shape.

[0008]

【Example】

Examples will be described with reference to the drawings.

[0009] FIG. 2 shows the camera with the lens barrier 10 disassembled, and 1 indicates the camera. The bodies 2 and 3 include an upper cover and a lower cover that cover the upper and lower surfaces of the camera body 1. It's a bar.

0010 An electric switch type shutter button 4 is located on the top surface of the top cover 2. It is provided so as to be approximately flush with the surface.

[0011] Further, a photographic lens 5 is arranged near the center of the front surface of the camera body 1, and A finder window 6 is arranged in the section.

0012 The lens barrier 10 is formed of a flexible plate-like member. One end side is fixed to the side surface of the camera body 1 with a machine screw 11.

[0013] As shown in FIG. 3, the other end side of the lens barrier 10 includes an upper cover 2 and a lower cover. Guide pieces 12 and 13 that engage with the inside of the bar 3 are formed to protrude upward and downward. The guide pieces 12 and 13 slide horizontally along the front edges of the upper cover 2 and lower cover 3. can be id. Also, when you do that slide operation, your fingertips will act as a barrier to the lens. 10, the front surface near the end has a small uneven surface. A finger rest portion 15 is formed.

[0014] 16 is a compression coil coil loaded in the hole 7 drilled in the front of the camera body 1. The click ball is biased forward by the spring 17 and is shown in FIG. The lens barrier 10 is engaged with a click hole 18 formed on the back surface thereof.

[0015] As shown in FIG. 4, the click holes 18 (18a, 18b) are connected to the lens barrier 1. There are two formed on the back surface of 0 with an interval in the horizontal direction. And lens barrier 1 0 is closed, the click ball 16 engages with the click hole 18a for closing, When the lens barrier 10 is in the open state, the click ball 16 is in the open state. engages with the lock hole 18b. In this way, the lens barrier 10 can be safely opened and closed at each position. It can be held still at a fixed position.

[0016] FIG. 5 shows the lens barrier 10 in a closed state. In this state, The front surfaces of the shadow lens 5 and finder 6 are closed by a lens barrier 10, and the cover is closed. The mela has a simple rectangular parallelepiped shape with almost no unevenness as a whole.

[0017] From this state, place your fingertip on the finger rest 15 and move the lens barrier 10 in the opening direction (see the figure). 5 to the left), the lens barrier 10 will move as shown in FIG. The guide pieces 12 and 13 bend forward at the parts where they are not protruding, and the camera body 1 The click ball 16 protrudes in an arc shape and engages the click hole 18b for opening. Stable and stationary.

[0018] In this state, as shown in FIG. The viewfinder 6 is opened from the front and becomes ready for photographing. In addition, lens barrier 1 The part 10a that bends and protrudes forward of 0 is used to hold the finger of the hand holding the camera. The grip part allows you to hold the camera stably.

[0019] Then, if you slide the lens barrier 10 in the closing direction (rightward in Figure 1), it will open again. As shown in FIG. 5, the entire structure returns to a rectangular parallelepiped shape with no irregularities.

[0020] Note that the lens barrier 10 does not need to have flexibility as a whole, but at least It is sufficient that the portion that becomes the grip portion 10a has flexibility. In addition, the lens barrier 10 The finger rest portion may be formed by a groove 25 or the like, as shown in FIG.

[0021] In addition, the cross-sectional shape of the lens barrier 10 is changed so that the back surface side is wrapped as shown in FIG. If the lens barrier is formed into an uneven shape parallel to the tooth shape of a belt or a timing belt, etc. The flexibility of lens barrier 10 is increased, and the lens barrier 10 follows the sliding movement and becomes smoother. It begins to bend.

[0022] Furthermore, when the lens barrier 10 is opened, the grip portion 10a is not necessarily positioned forward. The grip part 1 does not need to be protruded, for example as shown in FIG. 0a may protrude to the side of the camera body 1, or may extend from the side to the front. It may be made to protrude in both directions.

[0023]

[Effect of the idea]

In the camera of this invention, when the lens barrier is closed, the lens barrier is attached to the camera body. Since the camera does not protrude from the camera, it is easy to carry when you put it in your pocket or handbag. It has good elasticity, and when you open the lens barrier, the flexible part of the lens barrier will touch the camera body. A grip part is formed that protrudes from the top, so it provides stable and excellent retention during use. Obtainable.
