Description

  The present invention relates to a camera mounting structure for freely mounting a tripod adapter to a small camera.

Small industrial cameras are often used by attaching to a tripod. However, in order to enable the camera to be used in various postures, the camera is attached to the tripod via an adapter.
When using the camera in an upright position, a tripod adapter (hereinafter simply referred to as an adapter) is attached to the bottom of the camera body. Is provided. Similarly, the adapter is also provided with mounting holes, and both are fixed with mounting screws. Further, when the camera is used in a suspended state, the adapter is attached to the upper surface of the camera body, so that an attachment hole for fixing the adapter is also provided on the upper surface of the camera body. As described above, the structure in which the adapter can be attached to both the bottom surface and the top surface of the camera body increases the degree of freedom of the camera installation state. In that case, the camera can be stably supported by providing the mounting holes at the four corners of the bottom surface and the top surface of the camera body. Moreover, a common adapter can be used by making the space | interval of an attachment hole into the same dimension by the upper surface and a bottom face.

  On the other hand, Patent Document 1 discloses a camera tripod assisting tool that enables the posture of a camera to be used in a horizontal position (upright state) and a vertical position (90-degree rotated state). The structure includes a holding member to which the camera can be attached by a tripod screw hole of the camera, and an angle turning mechanism capable of turning the holding member around the lens axis of the camera. In this case, it is stated that the position (horizontal position, vertical position) of the camera can be easily changed by the angle rotation mechanism.

Japanese Patent Laid-Open No. 2001-255584

  In recent years, with the diversification of the usage environment of small cameras, there is a demand that the camera and adapter can be attached not only on the bottom and top surfaces of the camera body but also on both sides. In order to realize this, a structure in which mounting holes are provided on the four surfaces of the camera body is required.

  In order to correspond to the four-surface mounting structure, when a mounting hole for fixing the adapter is added to the side surface of the camera body, there arises a problem that the mounting holes interfere with each other. That is, since the mounting holes provided on the side surfaces are arranged close to the mounting holes provided on the bottom surface or the top surface, the bottoms of the mounting holes easily interfere with each other. The reason is that in order to attach the camera body and the adapter stably, the mounting holes are often provided at the four corners of the mounting surface with a large interval. In order to avoid this interference, the size of the camera body may be increased while leaving the interval between the mounting holes as it is. However, if the outer shape is increased, the size of the camera is reduced. Alternatively, if the mounting hole position is changed to reduce the distance between the mounting holes on both sides, there is no commonality between the bottom, top, and both sides when switching the mounting surface, and two types of adapters must be prepared. .

  On the other hand, the structure of Patent Document 1 can rotate the posture of the camera 90 degrees between the horizontal position and the vertical position. However, in order to change the mounting surface from the bottom surface to the top surface, the angle is 180 degrees. A rotation width is required, and it is difficult to realize an angle rotation mechanism that satisfies this. In addition, the angle rotation mechanism is complicated and large, and the camera system including the adapter is large.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a camera mounting structure capable of freely mounting a common tripod adapter on four surfaces of a camera without increasing the size of the camera.

  The present invention is a camera mounting structure for mounting a tripod adapter to a camera body, and mounting holes for mounting a tripod adapter are provided at each corner of each mounting surface on the bottom surface, top surface, and both side surfaces of the camera body. Each mounting surface has a combination of two different values W1 and W2 for the distance between the two mounting holes provided on the front side of the camera body and the distance between the two mounting holes provided on the rear side of the camera body. The arrangement of the mounting holes provided on both sides is opposite to the arrangement of the mounting holes provided on the bottom surface and the top surface, on the front side and the rear side of the camera body.

  According to the present invention, a common tripod adapter can be freely attached to the four surfaces of the camera without increasing the size of the camera.

The perspective view which showed one Example of the attachment structure of the camera by this invention, and was seen from the camera back. FIG. 3 is a cross-sectional view of the front frame 2 showing a cross-sectional shape of a mounting hole of the camera body. Cross-sectional view of rear frame 3 showing the cross-sectional shape of the mounting holes in the camera body The perspective view which showed an example of the structure of the tripod adapter 7, and was seen from the tripod attachment side. The perspective view which showed an example of the structure of the tripod adapter 7, and was seen from the camera main body side. The figure which shows the attachment method of a camera main body and the tripod adapter.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1A and 1B show an embodiment of a camera mounting structure according to the present invention, FIG. 1A is a perspective view seen from the front (and the top side) of the camera, and FIG. 1B is seen from the back (and the bottom side) of the camera. It is a perspective view.

  A camera body (hereinafter referred to as camera body) 1 includes a front frame 2 and a rear frame 3 as housings, housing electronic components therein and protecting them with a cover 4, and for connecting an imaging lens 5 and a signal cable. It has an external structure to which the connector 6 is attached. A plurality of attachment holes are provided around the camera body 1 for attaching a tripod adapter 7 described later. In this embodiment, the mounting surface of the tripod adapter 7 can be mounted not only on the bottom surface 1a and the top surface 1b of the camera body 1 but also on the side surface 1c, and four mounting holes (screw holes) are provided at the corners of each mounting surface. ). That is, mounting holes 2a and 3a for mounting the tripod adapter 7 to the bottom surface 1a, mounting holes 2b and 3b for mounting to the top surface 1b, and mounting holes 2c and 3c for mounting to the side surface 1c are formed. Of these mounting holes, the front side (lens 5 side) mounting holes 2a, 2b, 2c are in the front frame 2, and the rear side (connector 6 side) mounting holes 3a, 3b, 3c are in the rear frame 3. Is formed. Although not shown in the drawing, the mounting holes 2c 'and 3c' are similarly formed on the side surface 1c 'opposite to the side surface 1c, but will be omitted in the following description.

  2A and 2B show the cross-sectional shape of the mounting hole of the camera body, FIG. 2A is a cross-sectional view of the mounting hole formed on the front side (front frame 2), and FIG. 2B is formed on the rear side (rear frame 3). It is sectional drawing of the attachment hole to do.

  In this embodiment, two values in which the distance between the mounting holes on each mounting surface is different between the front side and the rear side are combined. Furthermore, the arrangement of the mounting holes on the front side and the rear side is reversed depending on the positions of the mounting surfaces (bottom surface / upper surface and side surfaces). Specifically, the interval between the mounting holes formed in the bottom surface 1a and the top surface 1b is a wide size W1 on the front side (2a, 2b) and a narrow size W2 on the rear side (3a, 3b). On the other hand, the interval between the mounting holes formed on the side surface 1c is set to the narrow size W2 on the front surface side (2c, 2c ′) and the wide size W1 on the rear surface side (3c, 3c ′). ing.

  As a result, the arrangement of the four mounting holes on each mounting surface is a trapezoidal apex position having two sides W1 and W2 on any mounting surface, so that a common tripod adapter can be used. . In addition, the interval between the mounting holes in the cross section on the front side or the rear side is such that one of the bottom surface and the side surface or the top surface and the side surface has a narrow width W2, so that the mounting holes close in the front frame 2 and the rear frame 3 Interference between 2a and 2c, 3a and 3c can be avoided. And it can avoid that a camera main body enlarges by making one of the space | intervals of an attachment hole into narrow W2.

  In this embodiment, the interval between the mounting holes formed on the bottom surface 1a and the top surface 1b is set to the wide size W1 on the front side (2a, 2b) and the narrow size W2 on the rear side (3a, 3b). Needless to say, the narrow size W2 on the front side (2a, 2b) and the wide size W1 on the rear side (3a, 3b) may be used.

3A and 3B show an example of the structure of the tripod adapter 7, FIG. 3A is a perspective view seen from the tripod mounting side, and FIG. 3B is a perspective view seen from the camera body side.
The tripod adapter 7 is provided with four mounting holes 8f and 8g for mounting the camera body 1. Mounting screws 9 are inserted into these mounting holes 8f and 8g, and fixed to the mounting holes 2a to 2c and 3a to 3c provided in the camera body 1. A tripod attachment hole 10 for attaching a tripod (not shown) is provided at the center of the tripod adapter 7.

  The distance between the mounting holes 8f and 8g provided in the tripod adapter 7 is set equal to the distance between the mounting holes 2a to 2c and 3a to 3c provided in the camera body 1. That is, the pair of mounting holes 8f are formed to be equal to the wide size W1, and the other pair of mounting holes 8g are formed to be equal to the narrow size W2. Thereby, it becomes possible to attach to any attachment surface of the camera body 1 with one tripod adapter 7.

  FIG. 4 is a view showing a method for attaching the camera body and the tripod adapter 7. A case where a common tripod adapter 7 is attached to four surfaces of the bottom surface 1a, the top surface 1b, the side surface 1c, and the side surface 1c ′ as the mounting surface of the camera body 1 is shown (in the drawing, the top surface 1b and the side surface 1c ′ are the back side of the camera body 1). Located). The posture of the tripod adapter 7 when attached to the bottom surface 1a and the top surface 1b is indicated by 7a and 7b, respectively. The posture of the tripod adapter 7 when attached to the side surface 1c and the side surface 1c 'is indicated by 7c and 7c', respectively. The intervals between the mounting holes provided in the side surface 1c and the side surface 1c 'are reversed on the front surface side and the rear surface side with respect to the intervals W1 and W2 between the mounting holes provided on the bottom surface 1a and the top surface 1b of the camera body 1. Therefore, when attaching the tripod adapter 7 to the side surfaces 1c and 1c ', the front-rear direction of the tripod adapter 7 may be reversed. In this way, the common tripod adapter 7 can be freely attached to the four surfaces around the camera body.
