BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a positioning device for mounting a mounting element such as a light receiving element on a flexible substrate to be positioned and mounted on a mounting member such as a camera.

[0002]

2. Description of the Related Art For example, in a camera,
When a light receiving element that receives light for photometry, a light receiving element that receives light for distance measurement, or a light receiving element that receives a light beam for remote operation emitted from a remote controller separate from the camera body is attached to the camera body. There is a method in which the light receiving element is mounted on a flexible substrate, and the flexible substrate in that state is mounted on a camera body. In such a mounting method, for example, two positioning projections are provided on the camera body, two positioning mounting holes corresponding to the positioning projections are provided on the flexible substrate, and both mounting holes are connected to the two positioning projections. And the two positioning projections are fitted into the two mounting holes respectively, and the flexible substrate is mounted on the camera body.

When a light receiving element is mounted on a flexible board, for example,
A reading land portion having two orthogonal reference lines is formed, and the light receiving element is mounted at an appropriate position by a mounter based on the reading of the two orthogonal reference lines of the land portion.

However, since the reading land portion and the mounting hole are provided on the flexible substrate by separate processes, the relative positions of both may be shifted depending on the case. In this case, even if the flexible board is properly mounted on the camera body, the position of the light receiving element with respect to the mounting hole is already shifted, so this light receiving element should be positioned at the front of the lens. Therefore, the relative position between the light receiving element and the lens is displaced, which causes a problem that the center position between the light receiving element and the lens is displaced.

[0005]

The purpose of the present invention is to solve the above-mentioned conventional problems. The present invention is based on such a problem that a relative position between a reference surface of a reading land or the like and a mounting hole is shifted. It is an object of the present invention to provide a flexible substrate positioning device capable of reliably eliminating a displacement of a mounting element.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a flexible board with two orthogonal reference lines for positioning a mounting element mounted on the flexible board, and a mounting member on which the flexible board is mounted. In a device provided with a mounting hole that fits into the provided positioning projection, the mounting hole is a non-circular hole, and the reference lines in the two orthogonal directions are provided on the inner peripheral contour of the non-circular hole. It is characterized by.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below based on illustrated embodiments. FIG. 4 is a front view of the camera to which the flexible substrate according to the present invention can be mounted. This camera is a camera body 1
0, a zoom lens 12 and a remote control unit 31 detachably attached to the camera body 10. In front of the camera body 10, a distance measuring unit 13, a viewfinder 1
4, a strobe 15 and a red self-lamp 16 which flashes at a predetermined cycle when the remote control unit 31 is removed. The camera body 10 is further provided with a release button 26 on an upper wall, a photometry window 17 below the finder 14, and infrared light and the like emitted from a remote control unit 31 below the self-lamp 16. Is provided with a remote signal receiving window 18 for receiving the remote control signal.

A light receiving element (mounting element) 75 as shown in FIGS. 1 to 3 is provided on the distance measuring section 13, the light measuring window 17, and the remote signal receiving window 18 by, for example, a positioning device for a flexible substrate as described below. Can be attached. That is, two mounting holes 76 are formed on the flexible substrate 78 on which the light receiving element 75 is to be mounted, on both sides of the position where the light receiving element 75 is to be mounted. The mounting holes 76 are used to position the flexible substrate 78 on the camera body (member to be mounted) 10, and have a shape that is a reference line in two orthogonal directions to be a reference when mounting the light receiving element 75 by the mounter. It has a rectangular shape with two sides 76a and 76b. That is, the flexible substrate 75 according to the present invention is conventionally provided with the mounting holes 76 as land portions for reading.
The two orthogonal reference lines, which were completely separate from
It is formed directly in the mounting hole 76.

The camera body 10 includes a distance measuring unit 13 and a photometric window 1.
7 and two fixed projections 77 to be fitted into the two mounting holes 76 of the flexible board 78 are provided on the fixed portion inside the camera corresponding to the remote signal receiving window 18. A corresponding lens frame 79 for supporting the light receiving lens 80 is provided. The two positioning projections 77 have the same inner diameter as the inner diameter of both mounting holes 76.

When the light receiving element 75 is mounted on the camera body 10 by the flexible substrate positioning apparatus having the above-described configuration, first, the reference line 76a in one of the two mounting holes 76 has two orthogonal directions. And 76b are read, and the light receiving element 75 is mounted at an appropriate position between the two mounting holes 76 by the mounter based on the read data. Thereafter, the flexible board 78 on which the light receiving element 75 is mounted is pressed against the two positioning projections 77 of the camera body 10 so that the two mounting holes 76 correspond to each other. To fit.

Thus, the flexible substrate 78 is mounted on the mounter 76 using the mounting hole 76 itself as a positioning reference.
The light-receiving element 75 mounted on the camera body 10 has an appropriate relative position with respect to the two mounting holes 76, and the flexible substrate 78 in which the two mounting holes 76 are positioned on the two positioning projections 77 is connected to the camera body 10. Since the relative position, that is, the relative position with respect to the light receiving lens 80 supported by the lens frame 79 is made appropriate, the relative position between the light receiving element 75 and the light receiving lens 80 is made appropriate. Therefore, the conventional drawback caused by providing the reference line and the mounting hole in the flexible substrate by separate processes is surely solved.

In this embodiment, the mounting element of the present invention is described as a light receiving element, and the mounted member is described as a camera. However, the present invention is not limited to this. Other electronic components may be applied, and members other than the camera may be applied to the mounted member.

[0013]

As described above, according to the present invention, the mounting hole of the flexible substrate is a non-circular hole, and the reference lines in the two orthogonal directions are provided on the inner peripheral contour of the non-circular hole. In addition, it is possible to reliably eliminate the displacement of the mounting element such as the light receiving element caused by the displacement of the relative position between the mounting line and the reference line of the reading land.
