Description

  The present invention relates to an electronic apparatus including a lens barrel and an image sensor.

  2. Description of the Related Art Conventionally, many electronic devices including a lens barrel and an image sensor such as a digital camera use a flexible printed circuit board for connection between electronic components (Patent Document 1). FIG. 9A is a horizontal cross-sectional view of a main part showing an example in which an imaging device and a printed board are connected by a flexible printed board in the digital camera.

  The digital camera shown in FIG. 9A is provided with an image sensor 204 such as a CCD sensor on the rear side (back side) of the lens barrel 200, and the lens group of the lens barrel 200 is attached to the image sensor 204. The passing subject light forms an image. On one side (right side) in the radial direction of the lens barrel 200, a battery storage portion 500 for storing the battery 502 in a removable manner is provided adjacent to the lens barrel 200. On the back side of the battery storage unit 500 and the lens barrel 200, a display unit 302 such as an LCD is provided. Further, a printed circuit board 100 is provided on the front side (subject side) of the battery storage unit 500, and a BtoB connector 104 is attached to an end of the printed circuit board 100 on the lens barrel 200 side. A BtoB connector means a board-to-board connector that connects boards together.

  The flexible printed circuit board 201 extending from the image sensor 204 passes between the lens barrel 200 and the display unit 302 and then extends forward between the lens barrel 200 and the battery storage unit 500. Further, it extends further to the right, and its extended end is disposed opposite to the front side of the printed circuit board 100. A BtoB connector 103 is provided at the extended end of the flexible printed circuit board 201. By inserting the BtoB connector 103 into the BtoB connector 104 on the printed circuit board 100 side, the image sensor 204 and the printed circuit board 100 are electrically connected via the flexible printed circuit board 201.

  By the way, the flexible printed circuit board 201 needs to be designed longer by the stroke in the front-rear direction when the BtoB connector 103 is inserted into the BtoB connector 104 on the printed circuit board 100 side. For this reason, as shown in FIG. 9B, when the BtoB connector 103 is connected to the BtoB connector 104, the flexible printed circuit board 201 is bent due to the excessive portion. As a result, a tensile force or a compressive force is applied, and a pressing force may be applied to the display unit 302 (X portion in FIG. 9B). If the pressing force applied to the display unit 302 is too large, moire may occur on the display screen.

FIG. 1C is a perspective view of the digital camera viewed from the front side with the flexible printed circuit board removed.

  This digital camera has a lens barrel 200. Hereinafter, the optical axis direction of the lens barrel 200 is referred to as the front-rear direction, and the subject side (the front side of the lens barrel 200) is referred to as the front side. The left-right direction is referred to as the direction seen from the photographer. For example, in FIGS. 1A and 1C, the front surface, the upper surface, and the left side surface are visible.

  FIG. 2 is a horizontal sectional view of a main part (intermediate part in the left-right direction) of the digital camera.

  As shown in FIG. 2, the digital camera has a lens barrel 200 on the front side (front side), and an imaging element 204 such as a CCD sensor on the back side (rear side) of the lens barrel 200. Yes. Adjacent to the lens barrel 200 in the radial direction, there is provided a battery storage unit 500 for storing the battery 502 in a removable manner. In this example, the battery storage unit 500 is disposed on the right side of the lens barrel 200. The battery storage unit 500 is fixed to the main chassis 600 with screws or the like.

  A display unit 302 such as an LCD is provided on the rear side of the battery housing unit 500 and the image sensor 204. A printed circuit board 100 is provided on the front side of the battery storage unit 500 (see also FIG. 1). Here, the battery housing part 500 corresponds to an example of the interior member of the present invention, and the printed circuit board 100 corresponds to an example of the wiring board of the present invention.

  A card connector 102 to which a recording medium 101 such as a memory card is detachably mounted is mounted on the back side of the printed circuit board 100. The card connector 102 reads and writes signals of the attached recording medium 101. Instead of the recording medium 101, a built-in memory may be provided. A BtoB connector (first connector) 104 that is a board-to-board connector is mounted on the front end of the printed board 100 on the side close to the lens barrel 200. A CPU 105 that controls the entire camera is mounted on the front side of the printed circuit board 100 (FIGS. 1A and 1C). The camera also includes a flexible printed circuit board 201.

  FIG. 3 is a block diagram showing a control configuration of the digital camera.

  As shown in FIG. 3, the digital camera includes an imaging control unit 106 that processes and converts an imaging signal, and a lens control unit 202 that controls driving of the lens group 203 of the lens barrel 200. These are mounted on the front side of the printed circuit board 100 (not shown in FIGS. 1 and 2).

  The printed circuit board 100 is mounted with a memory 110. The memory 110 stores data that should be retained even when the digital camera is turned off, such as setting information by a user and adjustment values at the time of shipment. Yes. The CPU 105 gives a shooting operation start instruction to the imaging control unit 106 and the lens control unit 202 in accordance with a user operation on the operation unit 108, and performs various controls such as a switching process between shooting and playback modes.

  As shown in FIG. 3, when the CPU 105 drives the lens group 203 of the lens barrel 200 by the lens control unit 202, the subject light that has passed through the lens group 203 forms an image on the imaging surface of the imaging element 204. The subject light imaged on the imaging surface of the imaging element 204 is photoelectrically converted into an image signal and transmitted to the imaging control unit 106 of the printed circuit board 100 via the flexible printed circuit board 201.

  The CPU 105 drives the image sensor 204 via the flexible printed board 201 by the image capturing control unit 106 to acquire a photoelectrically converted image signal, and the A / D conversion unit 107 converts it into a digital signal. In addition, the CPU 105 performs signal processing on the A / D converted image signal and outputs it as image data to the recording medium 101 (FIG. 2) via the card connector 102. At the time of shooting or reproduction, the CPU 105 outputs image data to the display unit 302, whereby the image data is displayed on the display screen of the display unit 302.

  By the way, the CPU 105 is disposed near the center of the printed circuit board 100 so as not to cross the wirings, and is located at substantially the same height as the image sensor 204. The image sensor 204 is located near the back of the camera, but the BtoB connector 104 is located near the front of the camera. The image sensor 204 is located on the left side in the left-right direction, but the BtoB connector 104 is located on the right side. In such a situation, an arrangement of the flexible printed circuit board 201 that electrically connects the image sensor 204 and the printed circuit board 100 will be described.

  FIG. 4A is a front view of the digital camera showing a state in which the lens barrel 200, the printed circuit board 100, and the flexible printed circuit board 201 are assembled. FIG.4 (b) is A arrow view (right view) of Fig.4 (a). 5A and 5B are enlarged horizontal sectional views of the vicinity of the rear end of the right end portion of the lens barrel 200. FIG. FIG. 6A is a developed rear view of the flexible printed circuit board 201. FIG. 6B is a perspective view of the vicinity of the image sensor 204 of the flexible printed board 201 as viewed from the back.

  As shown in FIG. 6 (a), the flexible printed circuit board 201 is integrally formed with a wide sheet-like shape from the image sensor mounting portion 201c that is one end portion to the connector mounting portion 201b that is the other end portion. Have The image pickup device 204 is attached to the front surface of the image pickup device attachment portion 201c in the arrangement state (see also FIG. 2), and the BtoB connector (second connector) 103 is attached to the rear surface of the connector attachment portion 201b (FIG. 2, FIG. (See also FIG. 4 (b)). A connector reinforcing portion 201f is disposed on the front surface of the connector mounting portion 201b (FIGS. 1A, 2, and 4).

  The imaging element attachment portion 201c is connected to the connector attachment portion 201b via the first extension portion 201d, the second extension portion 201e, and the drawer portion 201a. The first extending portion 201d is inclined obliquely upward from the image sensor mounting portion 201c toward the second extending portion 201e. The lead-out portion 201a is adjacent to the second extension portion 201e, and the connector mounting portion 201b extends downward from the lead-out portion 201a in an L shape. In the arrangement state, only the second extending portion 201e extends along the optical axis direction. Two stopper portions 201g, which are engaging pieces, are extended and formed on the outer side in the width direction at a position near the drawer portion 201a of the second extension portion 201e.

  As shown in FIG. 2, the flexible printed circuit board 201 is arranged by the following route. First, between the lens barrel 200 and the display unit 302, a first extending portion 201d extending rightward from the imaging element mounting portion 201c is a portion where the outer shape of the lens barrel 200 and the battery storage unit 500 are in contact with each other. Extend to detour. The first extending portion 201d extends in parallel in the vertical and horizontal directions at a position slightly behind the image sensor mounting portion 201c. As shown in the figure, a substantially cylindrical lens barrel 200 and a substantially rectangular parallelepiped battery storage portion 500 are arranged in the radial direction of the lens barrel 200. By bringing the lens barrel 200 and the battery storage unit 500 as close as possible, the external shape of the digital camera can be reduced in size. For this reason, the center of the lens barrel 200 in the vertical direction is arranged so as to be in contact with the battery storage unit 500. Accordingly, the first extending portion 201d is formed to bypass the center in the vertical direction of the lens barrel 200 as illustrated in FIG. Of the flexible printed circuit board 201, the first extending part 201 d sandwiched between the lens barrel 200 and the display part 302 is closest to the display part 302. That is, the first extending portion 201 d extends along the back surface of the lens barrel 200 on the front side of the display portion 302.

  When the flexible printed circuit board 201 passes through the back surface of the lens barrel 200 from the first extending portion 201d, the flexible printed circuit board 201 is bent forward at a right angle via the curved connecting portion 201j and continues to the second extending portion 201e (FIG. 5). In other words, the second extending portion 201e connected from the right end of the first extending portion 201d via the R-shaped connecting portion 201j extends forward in the optical axis direction between the lens barrel 200 and the battery housing portion 500. . And the 2nd extension part 201e is extended to the position before the printed circuit board 100 in the front-back direction (FIG. 2, FIG.4 (b)).

  When the second extending portion 201e reaches the front of the printed circuit board 100, the second extending portion 201e is bent and bent to the right at a right angle, and continues to the drawer portion 201a. That is, the lead-out portion 201a is pulled out from the second extension portion 201e to the right side to the front side of the printed circuit board 100. The drawer portion 201a is parallel to the image sensor mounting portion 201c. Not only the connection part 201j between the first extension part 201d and the second extension part 201e but also the bent part at a right angle between the second extension part 201e and the lead part 201a is minimized so that the wiring pattern is not cut. R (roundness) shape is attached.

  A connector mounting portion 201b extends downward from a lower portion on the right side of the drawer portion 201a. In other words, the connector mounting portion 201b extends downward from the second extending portion 201e in a direction perpendicular to the pulling direction (rightward) of the pulling portion 201a when viewed from the optical axis direction.

  Here, the wiring pattern in the flexible printed circuit board 201 has a form in which a plurality of signal patterns are arranged in parallel in the width direction. In the second extending portion 201e, the wiring pattern is along the left-right direction. In the connector mounting portion 201b, it is along the vertical direction. In the lead-out portion 201a, the direction of the wiring pattern changes in the middle, and in the region close to the second extending portion 201e, it follows the horizontal direction, but in the region close to the connector mounting portion 201b, it follows the vertical direction.

  In the state in which the flexible printed circuit board 201 is arranged in this manner, as shown in FIG. 2, the drawer part 201a, the connector mounting part 201b, and the connector reinforcing part 201f are all located on the front side of the printed circuit board 100. Almost parallel to 100. By inserting and connecting the BtoB connector 103 of the flexible printed circuit board 201 to the BtoB connector 104 of the printed circuit board 100 from the front, the image sensor 204 and the printed circuit board 100 are electrically connected via the flexible printed circuit board 201.

  At the time of “connector connection” in which the BtoB connector 103 is connected to the BtoB connector 104, the tip portion of the connector mounting portion 201b where the BtoB connector 103 is provided is displaced rearward. Then, the narrow part of the connector mounting portion 201b, particularly in the width direction (left-right direction), is bent. This is because the BtoB connector 103 is not provided in the drawer portion 201a, but is provided in the connector attachment portion 201b drawn from the drawer portion 201a. Further, this is because the pull-out direction of the pull-out portion 201a and the extending direction of the connector mounting portion 201b are different (orthogonal). In particular, since the actual distance from the connecting portion between the second extending portion 201e and the lead-out portion 201a to the BtoB connector 103 follows a path that is bent at a right angle in the middle, it is connected with the shortest distance as in the prior art (FIG. 9). It is longer than Therefore, the area | region which can bend becomes long and the force by which the 2nd extension part 201e is urged | biased back at the time of connector connection is suppressed.

  As a result, the rearward displacement of the second extending portion 201e when the connector is connected can be small. Therefore, it is avoided that the first extending part 201 d closest to the display unit 302 abuts against the display unit 302 and applies a pressing force. That is, the connector mounting portion 201b is mainly bent to absorb the extra length of the flexible printed circuit board 201 and absorb the tensile force or the compressive force, thereby preventing the pressing force from being applied to the display portion 302. Yes.

  The device for preventing the interference of the flexible printed circuit board 201 with the display unit 302 is not limited to this. First, as shown in FIG. 4B, the lens barrel 200 includes a flexible restraining portion (second regulating portion) 700 corresponding to the stopper portion 201 g of the second extending portion 201 e of the flexible printed circuit board 201. Is provided. The flex suppressing part 700 extends so as to face the right side surface of the second extending part 201e through both sides in the width direction of the second extending part 201e in the thickness direction. When the flexible printed circuit board 201 is disposed, the stopper portion 201g is positioned on the front side of the flexible portion suppressing portion 700.

  Even if the second extending portion 201e tries to be largely displaced rearward when the connector is connected, the stopper portion 201g hits and engages with the flexible member suppressing portion 700, and the second extending portion 201e moves backward further. Is regulated.

  Further, in addition to these, as shown in FIG. 5, a restricting portion (first restricting portion) 501 having a concave curved surface is integrally provided in the battery housing portion 500, and is formed at the rear portion of the right end portion of the lens barrel 200. A space CL is formed between the convex R portion 200a and the concave curved surface of the restricting portion 501. And the connection part 201j of the 1st extension part 201d and the 2nd extension part 201e is located in the space CL. The restricting portion 501 may be formed integrally with the battery housing portion 500, but may be configured as a separate body and fixed so as to be integrated. Here, FIG. 5A shows an example of a state before the BtoB connector 103 is connected to the BtoB connector 104, and FIG. 5B shows an example of a state after the connection.

  In a state before connector connection, the connecting portion 201j is in proximity to or in contact with the convex R portion 200a (FIG. 5A). On the other hand, after the connector connection, the second extending portion 201e is somewhat retracted, so that the connecting portion 201j curved in an R shape is deformed so as to escape toward the regulating portion 501 in the space CL. Even if the rearward displacement amount of the second extending portion 201e is large, when the connecting portion 201j contacts the restricting portion 501, the connecting portion 201j is not further displaced rearward. Accordingly, the first extending portion 201d is hardly displaced rearward, and the contact with the display portion 302 is avoided.

  By the way, there may be a difference in the curvature of the connecting portion 201j due to a horizontal shift or mounting error when the image sensor 204 is mounted. Therefore, if the degree of the difference is too large, the connecting portion 201j may come into strong contact with the restricting portion 501, and the first extending portion 201d may bend and come into contact with the display portion 302. Therefore, the position or shape of the concave surface of the restricting portion 501 is designed so as to be able to absorb the deviation and mounting error when the image sensor 204 is mounted.

  That is, as shown in FIG. 6B, the distance between adjacent terminals 204a in the image sensor 204 is defined as a pitch S (particularly a pitch in the left-right direction). The length corresponding to the amount by which the connecting portion 201j of the flexible printed circuit board 201 can be flexibly deformed without difficulty in the space CL is set to be longer than the pitch S. That is, the difference in the required length in the longitudinal direction of the flexible printed circuit board 201 between the state in which the connecting portion 201j is in close contact with the convex R portion 200a and the state in which the connecting portion 201j is in close contact with the regulating portion 501 is set to be larger than the pitch S.

  According to the present embodiment, in the flexible printed circuit board 201, the first extending part 201d to the second extending part 201e pass between the lens barrel 200 and the battery housing part 500 and are positioned in front of the printed circuit board 100. Extend to. And the drawer part 201a is pulled out from the second extension part 201e to the front side of the printed circuit board 100 to the right, and the connector mounting part 201b extends downward from the drawer part 201a, which is different from the drawer direction of the drawer part 201a. Is done. Thereby, when the BtoB connector 103 is inserted and connected to the BtoB connector 104, it is possible to prevent the display unit 302 from being pressed mainly by the first extension 201d of the flexible printed circuit board 201. Therefore, it is possible to prevent moiré from occurring on the display screen of the display unit 302.

  Furthermore, since the amount of displacement of the second extending portion 201e to the connecting portion 201j can be restricted by providing the restricting portion 501 and the flex suppressing portion 700, the display portion 302 is pressed by the first extending portion 201d. This can be avoided more reliably.

  By the way, in this Embodiment, the distance from the position (equivalent to the front end of the 2nd extension part 201e) extended before the printed circuit board 100 among the flexible printed circuit boards 201 to the BtoB connector 103 was securable. Thereby, it became advantageous for prevention of interference of the flexible printed circuit board 201 to the display unit 302. This can be said to be realized by the fact that the position in the height direction corresponding to the front end of the second extending portion 201e is not the same height as the connector mounting portion 201b but a high position. If it restrict | limits to such a viewpoint, the position corresponding to the front end of the 2nd extension part 201e should be separated as much as possible from the connector attaching part 201b, and may be lower than the connector attaching part 201b.

  The restricting portion 501 is provided in the battery housing portion 500, and the flex suppressing portion 700 is provided in the lens barrel 200. However, the present invention is not limited to this, and these may be provided in a portion fixed to the main body of the camera, that is, the main chassis 600.

  By the way, when the connector is connected, the connector attachment portion 201b is mainly bent, but the drawer portion 201a is also somewhat bent, and a force for biasing the second extension portion 201e backward also acts via the drawer portion 201a. Therefore, the more easily the connector mounting portion 201b is bent, the less influence is exerted on the drawer portion 201a, and the rearward urging force with respect to the second extension portion 201e can be reduced, and the interference between the first extension portion 201d and the display portion 302 can be reduced. It is advantageous for avoidance. Therefore, it is desirable that the connector mounting portion 201b be easily bent with respect to the drawer portion 201a. Such a modification is illustrated in FIGS.

  FIGS. 7A and 7B are front views of the main part of a digital camera employing the flexible printed circuit board 201 according to the first and second modifications. FIG. 8A is a diagram illustrating a wiring pattern of the flexible printed circuit board 201 according to the third modification. FIG. 8B is a front view of the main part of a digital camera employing the flexible printed circuit board 201 according to the fourth modification. In these examples, the configuration of the flexible printed circuit board 201 is different from the above-described embodiment, and the other configurations are the same.

  In the first modification shown in FIG. 7A, the width dimension of the narrow portion in the left-right direction connected to the drawer portion 201a in the connector mounting portion 201b is small. Specifically, the minimum width in the direction (left-right direction) orthogonal to both the extending direction (downward) and the thickness direction (front-back direction) of the connector mounting portion 201b is defined as Wb. On the other hand, the minimum width in the direction (vertical direction) orthogonal to both the drawing direction (right side) and the thickness direction (front-rear direction) of the drawer 201a is defined as Wa. The minimum width Wb is set smaller than the minimum width Wa.

  As shown in FIG. 7B, in the second modification, a notch portion 201h that bites inward in the width direction into a portion of the connector mounting portion 201b that is connected to the drawer portion 201a and has a narrow width in the left-right direction. Is formed on both sides. The shortest distance between the two notches 201h corresponds to the minimum width in the left-right direction, which is set to be smaller than the minimum width of the drawer 201a.

  In the third modification shown in FIG. 8A, in the lead portion 201a, the wiring of each signal pattern 201bb connected to the connector mounting portion 201b is larger than the wiring width of each signal pattern 201aa connected to the second extending portion 201e. The width is narrow (narrow). That is, the wiring width is changed in the middle of the lead-out portion 201a, but each signal pattern 201bb of the connector mounting portion 201b is uniformly narrower than the wiring width of each signal pattern 201aa. Each signal pattern width of the second extending portion 201e is the same as each signal pattern 201aa and is wide. Eventually, the maximum wiring width of each signal pattern is narrower at the connector mounting portion 201b than at the lead-out portion 201a. The wiring width may be expressed as a thickness.

  In the fourth modification shown in FIG. 8B, a thin region is provided in the connector mounting portion 201b to make it easy to bend. Specifically, the flexible printed circuit board 201 has a layer structure in which a signal pattern is wired on one side and a coverlay is applied. And in the connector attaching part 201b, the coverlay removal part 201i from which the coverlay is removed is provided in the surface on the side where it is not wired. The area where the cover lay removing portion 201i is provided is thinner and more easily bent than other portions.

  In the example of FIG. 8B, the cover lay removal portion 201i is provided not only at the connector attachment portion 201b but also at the drawer portion 201a, but may be provided only at the connector attachment portion 201b. Note that the method of reducing the thickness is not limited to this method, and a region thinner than the maximum thickness of the drawer portion 201a may be provided in the connector attachment portion 201b.

  By the way, if the extending direction of the connector mounting portion 201b is different from the pulling direction of the pulling portion 201a, there is a certain effect. Further, the direction is not necessarily perpendicular to the optical axis.

  Moreover, although the battery accommodating part 500 was illustrated as an interior member provided adjacent to the radial direction of the lens barrel 200, it is not limited thereto. The second extending portion 201e extends between the lens barrel 200 and the battery housing portion 500 and extends forward in the optical axis direction, but only needs to pass between the lens barrel 200 and the interior member adjacent thereto. It is not limited to extending parallel to the axis.

  In addition, the structure of this invention is not limited to what was illustrated above, A material, a shape, a dimension, a form, a number, an arrangement | positioning location, etc. can be suitably changed in the range which does not deviate from the summary of this invention. Further, although the digital camera is exemplified as the electronic device, the present invention is not limited to this, and various electronic devices including a lens barrel, an imaging element, and a display unit, for example, a portable information terminal may be used.
