<<< User interface unit and circuit board >>>
Next, the user interface unit 16 and the circuit board 36 will be described with reference to FIGS. 3 to 6. The user interface unit 16 is formed as a display unit that displays information of the image reading apparatus 10 as an example. In the present embodiment, the user interface unit 16 includes a base unit 38, a touch panel 40, and an LCD (liquid crystal display) panel 42.

The touch panel 40 in the present embodiment is configured as a known touch panel such as a resistive film type, a capacitance type, or a surface acoustic wave type.

  The base portion 38 is formed, for example, in a box shape opening in the + Z direction. An opening 38a (FIG. 6) is provided on the bottom surface of the base portion 38. A plurality of protrusions 38 b protruding from the base 38 are provided around the base 38. Each protrusion 38b is provided with a through hole 38c, and is configured to allow insertion of a fastening member 46 (FIG. 11) described later.

  The LCD panel 42 is attached to the opening 38 a with the display surface facing in the + Z direction. Furthermore, a touch panel 40 is attached to the top of the base portion 38 so as to cover the LCD panel 42.

  The circuit board 36 is configured as an electronic circuit to which a plurality of electronic components are attached. In the present embodiment, a plurality of through holes 36 a are formed in the outer peripheral portion of the circuit board 36. Furthermore, as an example, as shown in FIG. 4, the circuit board 36 is provided with a touch panel connector 36 b and an LCD panel connector 36 c on the upper surface side, and image reading unit connectors 36 d and 36 e on the lower surface side. .

  In FIG. 5, a flat flexible member 48 for transmitting input information in the touch panel 40 is extended from an end of the touch panel 40 in the −X direction. In the present embodiment, the flexible member 48 is configured as an FPC (flexible printed circuit board) known as an example. The end of the flexible member 48 in the −X direction is configured as a terminal portion 48 a, and the terminal portion 48 a is provided with a plurality of terminals (not shown). By inserting the terminal portion 48 a of the flexible member 48 into the touch panel connector 36 b of the circuit board 36, the touch panel 40 and the circuit board 36 are electrically connected.

  Similarly, as shown in FIG. 6, a flat flexible member 50 is also extended from an end of the LCD panel 42 in the −X direction. In the present embodiment, the flexible member 48 is configured as an FPC (flexible printed circuit board) known as an example. The end of the flexible member 50 on the −X direction side is configured as a terminal portion 50 a, and the terminal portion 50 a is provided with a plurality of terminals (not shown). By inserting the terminal portion 50a of the flexible member 50 into the connector 36c for the LCD panel of the circuit board 36, the LCD panel 42 and the circuit board 36 are electrically connected.

  6 and 13, the flexible member 48 extends from the user interface unit 16 to the circuit board 36 side (−X direction side), and is curved toward the device inner side (−Z direction side). First curved portion 48b, and then curved toward the circuit board 36 side (−X direction side) which is a direction different from the bending direction of the first curved portion 48b to form a second curved portion 48c. It is inserted into the touch panel connector 36b.

  Similarly, the flexible member 50 extends from the user interface unit 16 to the circuit board 36 side (−X direction side), and curves toward the device inner side (−Z direction side) to form the first curved portion 50 b. And then curve toward the circuit board 36 side (−X direction side) which is a direction different from the bending direction of the first bending portion 50 b to form a second bending portion 50 c and insert it into the LCD panel connector 36 c. It is done.

Here, the first bending portions 48b and 50b and the second bending portions 48c and 50c are in a completed state in the degree of bending (state in the lower view of FIG. 13) at the fixed position of the user interface unit 16 described later. In the invention, the first curved portions 48b, 50b and the second curved portions 48c, 50c refer to the curved portions (curved state) in a state where the device is completely assembled.
However, in the present embodiment, the first bending portions 48b and 50b and the second bending portions 48c in the completed state also in the temporary placement position of the user interface unit 16 (the state shown in FIGS. 6 and 13). A curvature of 50 c is formed. Hereinafter, for convenience of explanation, the first curved portion 48b, the first curved portion 50b, the second curved portion 48c, and the second curved portion including the curved portions in the temporary placement state (the curved portions different from the curved degree in the completed state) are included. It will be called "part 50c".

  Here, in order to explain the function and effect of the bending portion provided on the flexible members 48 and 50, the first bending portion 48b and the second bending portion 48c in the flexible member 48 taking the flexible member 48 as an example. The problem in the configuration not provided with will be described with reference to FIG. In the upper view of FIG. 7, the flexible member 48 extending from the touch panel 40 to the circuit board 36 side (−X direction side) extends straight along the X-axis direction without being bent, and the touch panel connector 36 b Inserted into the

  Here, the flat flexible member such as FPC or FFC is flexibly deformed in the flat surface or in the length direction of the flexible member, but the flat surface and the flexible member in the length direction (see FIG. In the width direction of the flexible member (the Y-axis direction in the upper drawing of FIG. 7), which is a direction intersecting the X-axis direction in the upper drawing of 7, it is difficult to softly deform and If so, a part of the wiring inside the cable such as FPC or FFC may break.

  As shown in the lower part of FIG. 7, the Y-axis direction (-Y direction in the lower part of FIG. 7) in which the touch panel 40 (user interface unit 16) is the direction of deformation of the flexible member with respect to the circuit board 36. When the positional displacement occurs, the flexible member 48 is difficult to deform in the displacement direction of the touch panel 40, and thus an undesirable force acts on the flexible member 48. As a result, in the flexible member 48, an unreasonable deformation may occur in the hard-to-deform direction due to an undesirable force, or the terminal portion 48a of the flexible member 48 may come out of the touch panel connector 36b. In the lower part of FIG. 7, a two-dot chain line portion denoted by reference numeral 40-1 indicates the position of the touch panel 40 before misalignment.

  Next, the function and effect of the curved portions provided on the flexible members 48 and 50 will be described with reference to FIGS. 8 and 9 by taking the flexible member 48 as an example. 8 and 9 show the state before the touch panel 40 causes a positional deviation with respect to the circuit board 36, and the lower figures in FIGS. 8 and 9 show the touch panel. 40 shows the state after the positional displacement of the circuit board 36 has occurred.

  In the upper view of FIG. 8 and the upper view of FIG. 9, the flexible member 48 extended from the touch panel 40 to the circuit board 36 side (−X direction side) is located on the path from the touch panel 40 to the circuit board 36. The first curved portion 48 b and the second curved portion 48 c are formed and connected to the circuit board 36.

  Here, in the lower view of FIG. 8 and the lower view of FIG. 9, the Y-axis direction (FIG. 8 and FIG. 8) in which the touch panel 40 (user interface unit 16) In the lower view of FIG. 9, when the positional deviation occurs in the −Y direction, the + Y direction side end of the first curved portion 48 b protrudes in the −X direction side and the −Y direction side end in the + X direction side fall back. On the other hand, in the second curved portion 48c, the + Y direction side end portion retreats to the -X direction side, and the -Y direction side end portion protrudes to the + X direction side. When the touch panel 40 is displaced relative to the circuit board 36 in the + Y direction which is the opposite direction to the above description, the deformation state of the first bending portion 48b and the second bending portion 48c is opposite to the above description. It will be in a deformed state.

  Therefore, in the first bending portion 48b, the degree of bending increases on the + Y direction side, and decreases on the −Y direction side. In contrast, in the second curved portion 48c, the degree of curvature decreases on the + Y direction side, and the degree of curvature increases on the −Y direction side. That is, in the first bending portion 48b and the second bending portion 48c, the degree of bending in the Y-axis direction, which is the direction in which deformation is difficult, becomes uneven, so that the touch panel 40 (user interface unit 16) and the circuit board 36 in the Y-axis direction. Misalignment can be tolerated.

  As a result, since the flexible member 48 is not forcibly deformed in the Y-axis direction, disconnection of the wiring in the cable and removal of the terminal portion 48a from the touch panel connector 36b can be suppressed or prevented. In the description, the flexible member 48 is taken as an example, but also in the flexible member 50, the first curved portion 50b and the second curved portion 50c are formed, and the first curved portion of the flexible member 48 is formed. Similar to the 48b and the second curved portion 48c, positional deviation between the touch panel 40 (user interface unit 16) and the circuit board 36 in the Y-axis direction can be tolerated.

<<< Assembly method of image reader >>>
Next, with reference to FIGS. 10 to 15, a method of assembling the image reading apparatus 10 will be described. As a first step, as shown in FIG. 3, the touch panel 40 and the LCD panel 42 constituting the user interface unit 16 are electrically connected to the circuit board 36 by the flexible members 48 and 50, respectively.

  Here, in FIG. 10, a circuit board fixing portion 52 is provided at the + Z direction side end portion of the main body portion 12. The circuit board fixing portion 52 includes a plurality of attachment portions 52a and a temporary placement portion 52b. The attachment portion 52 a is provided to correspond to the plurality of through holes 36 a provided in the outer peripheral portion of the circuit board 36 in the circuit board fixing portion 52. The mounting portion 52a is configured to be engageable with the fastening member 46 (FIG. 11). The temporary placement unit 52b is configured to support the user interface unit 16 in a posture (tilted posture) along the Y-axis direction.

  Ends of a first cable 54 and a second cable 56 extended from the image reading unit 30 in the main body 12 are disposed at the + Y axial direction side end of the circuit board fixing unit 52, respectively. In the present embodiment, the first cable 54 and the second cable 56 are configured as an FFC (flexible flat cable) as an example, but may be configured as an FPC or the like.

  Next, as a second step, as shown in FIG. 11, the circuit board 36 is arranged so that the mounting portion 52a and the through hole 36a are aligned with the circuit board fixing portion 52 of the main body portion 12. The fastening member 46 is inserted into the through hole 36a, and the fastening member 46 is fastened to the mounting portion 52a. Thus, the circuit board 36 is fixed to the circuit board fixing portion 52. The fastening member 46 is configured as a screw as an example, but may be a bolt or the like.

  The first cable 54 is inserted into the image reading unit connector 36d of the circuit board 36 fixed to the circuit board fixing unit 52, and the second cable 56 is inserted into the image reading unit connector 36e. And electrically connected. In the temporary placement unit 52b, the user interface unit 16 is temporarily placed in a posture along the Y-axis direction. A position where the user interface unit 16 is temporarily placed in the temporary placement unit 52b in the X-axis direction is a temporary placement position.

  As a third step, as shown in FIG. 12, the housing 14 is attached to the main body 12 so as to cover the + Z direction side end of the main body 12. Here, the case 14 is provided with an opening 14 a that exposes the user interface unit 16 temporarily placed to the outside of the apparatus when the case 14 is attached to the main body 12. Inside the opening 14a, a plurality of fixing portions 14b are provided. When the housing 14 is attached to the main body 12, the user interface unit 16 located in the opening 14a is exposed through the opening 14a. On the other hand, the circuit board 36 is covered by the housing 14.

  Here, since the user interface unit 16 is temporarily placed on the temporary placement unit 52b of the circuit board fixing unit 52, the position of the protrusion 38b of the base unit 38 is on the −X direction side with respect to the fixing unit 14b. It is in the wrong position.

  Next, as a fourth step in FIGS. 13 and 14, the user interface unit 16 is shifted from the temporary placement position to the + X direction side. As shown in FIG. 13, when the user interface unit 16 is shifted from the temporary placement position to the + X direction side, the degree of bending of the first bending portion 48 b and the second bending portion 48 c of the flexible member 48 becomes gentle. The degree of curvature is maintained to such an extent that positional deviation between the portion 16 and the circuit board 36 in the Y-axis direction can be tolerated. The same applies to the first curved portion 50 b and the second curved portion 50 c of the flexible member 50.

  As shown in FIG. 14, when the user interface unit 16 is shifted from the temporary placement position in the + X direction, the projection 38 b of the base 38 and the fixing unit 14 b overlap in the X axis direction. This position is taken as the fixed position of the user interface unit 16. Here, as a fifth step, the user interface portion 16 is fixed to the housing 14 by inserting the fastening member 58 through the through hole 38 c of the projecting portion 38 b and tightening the fixing portion 14 b. In addition, although the fastening member 58 is comprised as a screw as an example, a bolt etc. may be sufficient.

  Next, in FIG. 15, the cover panel 60 is attached to the opening 14a of the housing 14 in a sixth step. The cover panel 60 is configured to cover the opening 14a.
