Yes. A bottom wall 31A is disposed below the reading head 5, a rear side wall 31B is disposed behind the reading head 5, and a front side wall 31C is disposed in front of the reading head 5.

  The scanning mechanism 51 includes a driving pulley 52, a driven pulley 53, and a timing belt 54. The drive pulley 52 is disposed in the vicinity of the guide rail 31 </ b> F at the left end in the housing 31. The driven pulley 53 is disposed near the guide rail 31 </ b> F at the right end portion in the housing 31. The timing belt 54 is an endless belt wound around the drive pulley 52 and the driven pulley 53, and extends in the left-right direction along the guide rail 31F. A portion of the timing belt 54 that is disposed near the guide rail 31 </ b> F in the front-rear direction has a connecting portion 54 </ b> A that is connected to the carriage 50.

  The drive pulley 52 is driven by a drive source provided in the image reading unit 3 and is configured to be rotatable in the forward rotation direction and the reverse rotation direction. When the drive pulley 52 rotates in the forward direction, the connecting portion 54A of the timing belt 54 moves from the left side to the right side. Thereby, the carriage 50 and the reading head 5 also move integrally from the left side to the right side. On the other hand, when the driving pulley 52 rotates in the reverse direction, the connecting portion 54A of the timing belt 54 moves from the right side to the left side. As a result, the carriage 50 and the reading head 5 also move integrally from the right side to the left side. As described above, the reading head 5 can reciprocate in the left-right direction in the housing 31 by the rotation of the driving pulley 52 in the forward direction and the reverse direction.

  The FFC 6 can be configured as shown in FIG. 7, for example. The FFC 6 in FIG. 7 is integrally molded by sandwiching a plurality of conductors arranged at a predetermined interval in the width direction between two insulating films and an adhesive, and has flexibility. The FFC 6 is connected to a read head side terminal 6 </ b> A as an example of a connected portion connected to the connector 5 </ b> A of the read head 5 at an end in the longitudinal direction, and a control unit (not shown) provided in the main body 2. And a control unit side terminal 6B.

  The FFC 6 includes a first slit 6C, a second slit 6D, and a connecting portion 6E as an example of a first holding portion. The first slit 6C is formed in the longitudinal direction of the FFC 6 between the conductors between the fixed portion 6F and the connecting portion 6E and in the center of the FFC 6 in the short direction. The left end portion of the first slit 6C is located in the vicinity of the center in the longitudinal direction of the FFC 6 in this embodiment, but may be located in the vicinity of the control unit side terminal 6B.

  The second slit 6D is formed between the connecting portion 6E and the read head side terminal 6A, that is, on the read head side terminal 6A side of the first slit 6C, spaced apart from the first slit 6C and on the extension line of the first slit 6C. Has been. The connecting portion 6E is a portion where no slit is formed between the first slit 6C and the second slit 6D.

  Such an FFC 6 has an image in a state where a region from the left end portion of the first slit 6C to the right end portion of the second slit 6D is folded and overlapped along the line AA that is an extension line of the first slit 6C. It is attached to the reading unit 3. Since the FFC 6 has a configuration in which the FFC 6 is bent, the length in the short direction of the FFC 6 is shortened, so that the casing 31 can be made thinner. Hereinafter, one side of the folded FFC 6 is referred to as a first FFC 61 and the other side is referred to as a second FFC 62. By adopting a configuration in which the FFC 6 is bent, the first FFC 61 and the second FFC 62 can be manufactured by one FFC.

  Next, the arrangement of the FFC 6 will be described with reference to FIGS. 4 to 6 and FIG. The read head side terminal 6 </ b> A of the FFC 6 is connected to the connector 5 </ b> A of the read head 5. On the other hand, the control unit side terminal 6B of the FFC is connected to the control unit through an opening 31G communicating with the main body 2 formed near the rear side wall 31B.

  The FFC 6 has a fixed portion 6F fixed to the rear side wall 31B with a double-sided tape or the like at a position away from the bottom wall 31A. The fixed portion 6F is provided in a region in contact with the rear side wall of the FFC 6 when the reading head 5 is in the second position (see FIG. 6). That is, the portion fixed to the rear side wall 31B as the fixed portion 6F may be the entire region in contact with the rear side wall 31B, or may be a part of the region.

  The FFC 6 has a curved portion 6G that connects the read head side terminal 6A and the fixed portion 6F. The curved portion 6G is curved in a U shape from the rear side wall 31B to the front side wall 31C. The curved portion 6G is formed by the FFC 6 being supported by the holding portion 55 and the rear side wall 31B portion where the left end portion of the FFC 6 is in contact. The length of the part away from the rear side wall 31B of the bending portion 6G is the maximum when the reading head 5 is in the second position and the minimum when the reading head 5 is in the first position. The first FFC 61 is disposed on the inner peripheral side of the bending portion 6G, and the second FFC 62 is disposed on the outer peripheral side of the bending portion 6G so as to overlap the first FFC 61.

  8A and 8B are views for explaining the state of the FFC 6 in the vicinity of the holding unit 55. FIG. 8A is a partial cross-sectional view around the holding unit 55. FIG. 8B is a perspective view of the FFC 6 in the vicinity of the holding unit 55. As shown in FIG. 8A, a part between the connecting portion 6 </ b> E of the FFC 6 and the read head side terminal 6 </ b> A is held by the holding portion 55. The holding unit 55 includes a first block 55A, a second block 55B, a third block 55C, a fourth block 55D, and a fifth block 55E for forming a route for guiding the first FFC 61 and the second FFC 62.

  The first block 55 </ b> A extends in the front-rear direction and is disposed near the left and right center of the holding portion 55. The second block 55B is disposed with a gap on the left side of the front portion of the first block 55A. The third block 55C is arranged on the left side of the first block 55A and on the rear side of the second block 55B with a gap. The fourth block 55D is disposed on the left side of the first block 55A and on the rear side of the third block 55C with a gap. The fifth block 55E is a block that is bent at a right angle, and is arranged at intervals on the right side and the front side of the first block 55A and the front side of the second block 55B.

  The first guide 55 that guides the first FFC 61 is formed by the first block 55A, the second block 55B, the third block 55C, and the fourth block 55D. On the other hand, the first block 55A and the fifth block 55E form a second guide portion 57 that guides the second FFC 62.

  The first FFC 61 in the first guide portion 56 passes through between the first block 55A and the second block 55B in order from the connecting portion 6E side, passes between the second block 55B and the third block 55C, and passes through the third block. It curves along 55C, passes between the third block 55C and the fourth block 55D, and passes between the first block 55A and the fourth block 55D. On the other hand, the second FFC 62 in the second guide portion 57 is fixed to the fifth block 55E by the double-sided tape 58 between the second block 55B and the fifth block 55E, and bends at right angles along the fifth block 55E. It passes straight between the block 55A and the fifth block 55E.

  Therefore, the first FFC 61 in the first guide unit 56 is longer than the second FFC 62 in the second guide unit 57. In other words, it can be said that the first guide unit 56 is detoured so that the route for guiding the FFC 6 is longer than that of the second guide unit 57. With such a holding portion 55, the length of the second region 62A between the holding portion 55 of the second FFC 62 and the connecting portion 6E is larger than the length of the first region 61A between the holding portion 55 of the first FFC 61 and the connecting portion 6E. Length increases.

  Further, as shown in FIG. 8B, between the holding portion 55 and the reading head side terminal 6A, the first FFC 61 is folded back in the front-rear direction and the first turn-up portion 61B folded back in the front-rear direction. And the second folded portion 61C. On the other hand, between the holding part 55 and the read head side terminal 6A, the second FFC 62 has a folded part 62B folded from the front-rear direction to the up-down direction.

  Therefore, the first FFC 61 is longer than the second FFC 62 between the holding unit 55 and the read head side terminal 6A. With this configuration, the length of the second region 62A is further longer than the length of the first region 61A.

  As described above, since the length of the second region 62A is longer than the length of the first region 61A, the first region 61A of the first FFC 61 is pulled in the longitudinal direction and is in a straightly extended state. On the other hand, the second region 62A of the second FFC 62 is bent and curved in the longitudinal direction.

  Specifically, as shown in FIG. 8, the second region 62A is located between a portion connected to the holding portion 55 and the top portion 62T and is curved so as to warp with respect to the first region 61A. It has the site | part 62E1 and the top part 62T which is convex to the side away from 61 A of 1st area | regions. Further, the second region 62A has a portion 62E that is located between the top portion 62T and the connecting portion 6E and is curved so as to warp with respect to the first region 61A.

  As described above, the portion 62E1 and the portion 62E2 of the second region 62A are curved so as to warp with respect to the first region 61A, whereby an elastic force (from the second region 62A toward the first region 61A side) Resilience). Thereby, FFC6 is provided with the force which presses to the inner peripheral side (rear side) of the curved part 6G in 1st area | region 61A and 2nd area | region 62A. As a result, the FFC 6 can be prevented from greatly expanding. Therefore, buckling of the FFC 6 and interference with the scanning mechanism 51 can be suppressed.

  Further, since the length of the second region 62A is longer than the length of the first region 61A, the outer peripheral side of the curved portion 6G of the FFC 6 is the inner peripheral side when the reading head 5 is in the first position (see FIG. 4). It will be longer. Thereby, the stress concerning the curved part 6G becomes small and buckling of FFC6 can be suppressed. Further, by providing the holding portion 55, the length of the first region 61A and the length of the second region 62A can be made different even if the first FFC 61 and the second FFC 62 have the same length.

  Next, as shown in FIGS. 4 to 6, the connecting portion 6 </ b> E and the second region 62 </ b> A of the FFC 6 are arranged at positions away from the rear side wall 31 </ b> B regardless of the position of the reading head 5. That is, the connecting portion 6E and the second region 62A of the FFC 6 are disposed at a position away from the rear side wall 31B when the reading head 5 is at the first position (see FIG. 4).

  Accordingly, when the reading head 5 is in the first position (see FIG. 4), the connecting portion 6E and the second region 62A do not come into contact with the rear side wall 31B, so that the first region 61A and the second region 62A are formed. Since the curved portion 6G comes into contact with the rear side wall 31B, the vicinity of the connecting portion 6E is not separated from the rear side wall 31B, so that buckling in the vicinity of the connecting portion 6E can be suppressed.

[Modification]
In the above embodiment, the FFC 6 is an integrally molded product of the first FFC 61 and the second FFC 62, but the first FFC 61 and the second FFC 62 may be separate. That is, the FFC 6 may be manufactured using two FFCs. In this case, the connected portion corresponding to the reading head side terminal 6A includes a first connected portion that is an end portion of the first FFC and a second connected portion that is an end portion of the second FFC. And it replaces with the connection part 6E and a 1st holding | maintenance part can be formed by fixing two FFCs using a clip, a double-sided tape, etc.

  According to this configuration, the FFC 6 can be manufactured using a general-purpose FFC. In addition, by using two FFCs having different lengths, the second holding unit can be formed using a clip, a double-sided tape, or the like in the same manner as the first holding unit instead of the holding unit 55.

  In the above embodiment, the holding unit 55 is configured to have a longer path for guiding the FFC 6 than the second guide unit 57 due to the first guide unit 56 bypassing, but conversely the second guide unit bypasses. Therefore, the route for guiding the FFC 6 may be longer than that of the first guide unit. In this case, the length of the first region from the holding portion of the first FFC 61 to the connecting portion is longer than the length of the second region from the holding portion of the second FFC 62 to the connecting portion.

  Thus, since the length of the first region is longer than the length of the second region, the first region of the first FFC 61 is bent in the longitudinal direction and is in a curved state. On the other hand, the second region of the second FFC 62 is pulled in the longitudinal direction and is in a straightened state. As a result, the FFC 6 is less likely to deform due to the second region being pulled, and the FFC 6 can be prevented from greatly expanding. Thereby, buckling of the FFC 6 and interference with the scanning mechanism 51 can be suppressed.

  Thus, the 2nd holding | maintenance part should just be the structure hold | maintained in the state from which the length of the 1st area | region of 1st FFC61 and the length of the 2nd area | region of 2nd FFC62 differed. As a result, it is possible to prevent the FFC 6 from bulging greatly by giving a waist to the first region and the second region.

  Further, instead of the first FFC 61 or the second FFC 62, a flexible member such as a resin tape may be used. For example, when a flexible member is used instead of the second FFC 62, the flexible member is disposed outside the curved portion of the first FFC 61. One end portion of the flexible member is connected to the first FFC 61 by a first holding portion formed of a double-sided tape or the like provided between the fixed portion and the read head side terminal. On the other hand, the other end portion of the flexible member is held on the first FFC 61 by a second holding portion formed of a double-sided tape or the like provided between the first holding portion and the read head side terminal.

  The second holding portion is possible with the first FFC 61 in a state where the length of the first region from the holding portion of the first FFC 61 to the connecting portion is different from the length of the second region from the holding portion of the flexible member to the connecting portion. Holding the flexible member. Even with such a configuration, it is possible to prevent the FFC from bulging greatly by holding the first region and the second region.

  In the above-described embodiment, the multifunction apparatus has been described as an example of the image processing apparatus 1, but the image processing apparatus may be a scanner, an inkjet printer, a copying machine, or the like. The moving body when applied to the scanner is a reading head and a carriage for reading a document, and the moving body when applied to an inkjet printer is an ejection head and a carriage for discharging ink.

[Effect of the embodiment]
The image processing apparatus 1 according to the embodiment includes the reading head 5 that moves in the first direction. The image processing apparatus 1 also includes a rear side wall 31B disposed on one side of the reading head 5 in a second direction orthogonal to the first direction, and a front side disposed on the opposite side of the rear side wall 31B across the reading head 5. A housing 31 having a side wall 31C and a bottom wall 31A connecting the rear side wall 31B and the front side wall 31C is provided. The image processing apparatus 1 also connects the read head side terminal 6A connected to the read head 5, the fixed portion 6F fixed to the rear side wall 31B, and the curved portion connecting the read head side terminal 6A and the fixed portion 6F. An FFC 6 having a bending portion 6G is provided. And FFC6 has the 1st FFC61 arrange | positioned at the inner peripheral side of the bending part 6G, and the 2nd FFC62 arrange | positioned at the outer peripheral side of the bending part 6G. The image processing apparatus 1 includes a connecting portion 6E that is provided between the fixed portion 6F and the reading head side terminal 6A and connects the first FFC 61 and the second FFC 62. Further, the image processing apparatus 1 is a holding unit 55 provided between the connecting unit 6E and the reading head side terminal 6A, and the length of the first region 61A from the connecting unit 6E to the holding unit 55 of the first FFC 61 and the first area 61A. A holding unit 55 is provided that holds the first FFC 61 and the second FFC 62 in a state in which the length of the second region 62A from the connecting portion 6E to the holding unit 55 of the 2FFC 62 is different.

  According to this configuration, the length of the first region 61A and the length of the second region 62A are made different in the configuration in which the FFC 6 is arranged in a curved state from the rear side wall 31B side of the housing 31 to the read head 5 side. Thus, it is possible to prevent the FFC 6 from bulging greatly by giving the first region 61A and the second region 62A a waist. Thereby, buckling of the FFC 6 and interference with the scanning mechanism 51 can be suppressed.

  According to the image processing apparatus 1 of the above embodiment, the second area 62A is longer than the first area 61A.

  According to this configuration, by setting the second region 62A of the second FFC 62 arranged on the outer peripheral side of the bending portion 6G to be longer than the first region 61A, the FFC 6 moves to the inner peripheral side in the first region 61A and the second region 62B. A pressing force is applied, and the FFC 6 can be prevented from expanding.

  According to the image processing apparatus 1 of the above-described embodiment, the first holding unit and the second region 62A are located away from the rear side wall 31B regardless of the position of the reading head 5.
