JP 2005-19913 A

  By the way, for example, a strip-shaped flat cable (FFC) is used as an electric wire for transmitting an electrical signal such as image data in an electronic device including a scanner. The flat cable is held inside the device in the same manner as the lead wire 105, but may be removed when the electronic device is disassembled. For this reason, the flat cable is preferably held so that it can be easily removed. However, when the flat cable is held by the conventional holding structure as disclosed in Patent Document 1, when one end in the longitudinal direction of the flat cable is pulled, the side edge of the flat cable is protruded 101B to 103B. The wire in the flat cable may be broken. Removal of the flat cable requires careful attention, and there has been a problem that disassembly work cannot be performed efficiently.

  This invention is made | formed in view of this problem, and it aims at providing the electronic device which can be removed easily, without breaking a flat cable.

  (1) An electronic device according to the present invention is a strip-shaped flat cable having flexibility for transmitting an electrical signal, and on both sides of a bottom surface on which the flat cable is laid, wider than the flat cable. One side of the flat cable is disposed between a housing portion in which a side wall is disposed oppositely and an opening for receiving or taking out the flat cable between the side walls is formed on the distal end side of the side wall, and a bottom surface of the housing portion. A first claw portion provided with a gap into which the side edge of the housing portion can be inserted and projecting from one side wall of the housing portion toward the center in the width direction of the housing portion. The first claw portion is laid on the bottom surface and one side edge is hooked on the first claw portion so that the hook is released by a pulling force applied in the longitudinal direction of the flat cable. One side of the flat cable The side edges and has a guide portion for guiding the distal end side of the first claw portion.

  The flat cable transmits an electrical signal and is formed in a flexible strip shape. The flat cable is laid on the bottom surface of the housing portion. The side wall of the accommodating part is spaced apart wider than the flat cable, and is disposed opposite to both sides of the bottom surface. That is, the flat cable is laid in a flat state along the bottom surface between the side walls. An opening for accommodating or taking out the flat cable between the side walls is formed on the front end side of the side wall that is not in contact with the bottom surface. The flat cable is accommodated between the opening and the side wall, and is removed as necessary. The 1st nail | claw part is protrudingly provided toward the center of the width direction of the accommodating part from one side wall of the accommodating part. A gap is provided between the first claw portion and the bottom surface of the housing portion, and one side edge of the flat cable laid on the bottom surface is inserted into the gap. Thereby, since the laid flat cable is hooked by the first claw portion, the flat cable is not easily detached from the housing portion.

  The flat cable accommodated in the accommodating portion is laid on the bottom surface as described above, and one side edge is hooked on the first claw portion. When removing this flat cable, for example, a drawing force is applied in the longitudinal direction of the flat cable by lifting one end of the flat cable in the longitudinal direction. With this pulling force, the flat cable is pulled up from the bottom surface toward the opening. At that time, one side edge of the flat cable hooked on the first claw portion is guided to the distal end side of the first claw portion by the guide portion. When the side edge of the flat cable latched on the first claw portion is guided to the tip of the first claw portion, the latch is released and the flat cable is taken out from the housing portion. Thus, when a pulling force acts in the longitudinal direction of the flat cable, one side edge of the flat cable that is hooked to the first claw portion is guided by the guide portion so that the hook is released. The Therefore, it is possible to easily remove the attached flat cable without disconnecting it.

  (2) The guide portion may be configured such that an edge extending in the width direction of the housing portion is inclined with respect to the longitudinal direction of the housing portion. As a result, when a pulling force is applied to the flat cable in the longitudinal direction, one side edge of the flat cable is guided toward the center in the width direction of the housing part by the inclined guide part, and the latch is released. Is done.

  (3) On the other side wall of the housing portion, the contacted portion is brought into contact with the other side edge of the flat cable laid on the bottom surface, and one side edge of the flat cable is brought into contact with the one side wall. May be provided.

  The contacted part is provided on the other side wall of the accommodating part. When the flat cable is laid on the bottom surface with one side edge hooked on the first claw portion, the other side edge of the flat cable comes into contact with the contacted portion. Accordingly, the flat cable is pressed downward by the pressing force from the contacted portion, and one side edge of the flat cable comes into contact with one side wall of the housing portion. Therefore, since one side edge of the flat cable is reliably inserted into the gap between the first claw portion and the bottom surface, the flat cable can be reliably hooked by the first claw portion.

  (4) The contacted part may be provided with a pair at a position spaced apart from a position facing the first claw part on the other side wall by a predetermined distance in the longitudinal direction of the housing part. . A pair of contact portions are provided on the other side wall where the first claw portion is not provided. These contact parts are provided at positions that are separated from each other by a predetermined distance in the longitudinal direction of the housing part from a position facing the first claw part on the other side wall. In other words, the first contacted portion is provided at a position spaced a predetermined distance from the position facing the first claw portion on the other side wall to one side in the longitudinal direction of the housing portion. A second contact portion is provided at a position separated by a predetermined distance in the other direction. Therefore, the flat cable can be reliably hooked by the first claw portion while being pressed toward the gap below the first claw portion by these two contacted portions. In addition, since the to-be-contacted part is not provided in the position facing the 1st nail | claw part in the other side wall, compared with the case where the to-be-contacted part is provided in the position facing the 1st nail | claw part, it is a flat cable. There is an advantage that it is easy to insert one side edge into the gap below the first claw portion and to easily remove the attached flat cable.

  (5) A gap where the bent portion of the flat cable bent between the bent portion and the bottom surface of the bent portion can be inserted into the bent portion where the housing portion bends in an L shape along the bottom surface. The 2nd nail | claw part which protrudes toward the inner side wall from the outer side wall in a bending part may be provided.

  Since the flat cable has flexibility, it can be bent and attached. The accommodating portion is formed with a bent portion in which the accommodating portion is bent in an L shape along the bottom surface in order to bypass a predetermined place. The bent portion is provided with a second claw portion that protrudes from the outer side wall to the inner side wall in the bent portion. The 2nd nail | claw part is provided between the bottom face in a bending part with the clearance gap which can insert the bending part of the flat cable bent along the bottom face of a bending part.

  When a flat cable is attached, the bent portion of the flat cable bent in an L shape along the bottom surface of the bent portion is inserted into the gap between the second claw portion and the bottom surface, and the flat cable is inserted by the second claw portion. It is hooked. On the other hand, when removing the flat cable attached in this way, for example, by pulling up one end in the longitudinal direction of the flat cable, a pulling force is applied in the longitudinal direction of the flat cable. At that time, since the second claw portion is formed so that the gap between the second claw portion and the bottom surface opens toward the inner side wall of the bent portion, the flat cable is locked by the second claw portion. It can be easily released. Therefore, the attached flat cable can be easily detached from the bent portion of the housing portion without disconnecting the flat cable.

  (6) In the bent portion, a pair of sandwiching portions that project from each side wall toward the center in the width direction of the housing portion and sandwich the flat cable laid on the bottom surface in the width direction of the housing portion. It may be provided. A pair of the holding portions is provided so as to protrude from each side wall of the bent portion toward the center in the width direction of the housing portion. The flat cable laid on the bottom surface is hooked to the second claw portion at the bent portion and is held in the width direction of the housing portion by the pair of holding portions. Therefore, since the flat cable is held by the bent portion of the housing portion by the pair of holding portions in addition to the second claw portion, it is possible to make the shape of the second claw portion easier to remove the flat cable. It becomes.

  (7) A lid for closing the opening of the housing portion may be provided. Thereby, since the opening part of an accommodating part is obstruct | occluded with a lid | cover, there exists an advantage that it is not necessary to hold | maintain a flat cable firmly in an accommodating part. That is, it becomes possible to make the inside of the accommodating portion easier to remove the flat cable.

  According to the electronic device of the present invention, when a pulling force is applied in the longitudinal direction of the flat cable, one side edge of the flat cable hooked to the first claw portion is released by the guide portion. It is guided to the front end side of the 1st nail | claw part. Therefore, the flat cable attached to the accommodating portion can be easily detached without disconnecting.

The upper end of the carriage 224 is open, and the upper surface 227 of the CIS 32 mounted on the carriage 224 is exposed.

  A bearing portion 234 that fits with the fitting portion 231 of the CIS 32 is formed on one side of the wall 237. The bearing portion 234 is a long hole in the vertical direction, and the shaft 233 of the fitting portion 231 is inserted into the long hole so that the fitting portion 231 and the bearing portion 234 can be vertically moved within a predetermined range. Is done. The bearing portion 234 is disposed at a position corresponding to the pair of fitting portions 231. A concave portion 236 is formed on the other inner surface side of the wall 237 corresponding to the convex portion 235. By fitting the concave portion 236 and the convex portion 235 of the CIS 32, the positioning of the CIS 32 in the main scanning direction with respect to the carriage 224 is performed.

  In this embodiment, positioning in the sub-scanning direction is performed by the fitting portion 231 provided in the housing 228 of the CIS 32, and positioning in the main scanning direction is performed by the convex portion 235. However, the positioning of the CIS 32 with respect to the carriage 224 by these is merely an example, and the shape, positioning direction, and the like can be variously changed.

  At both ends in the longitudinal direction of the CIS 32, roller units 238 are provided. As shown in FIG. 5, holes 239 for positioning the roller unit 238 are formed at both ends of the upper surface 227 of the CIS 32. A pin protruding from the bottom surface of the roller unit 238 is fitted into the hole 239, and the roller units 238 are positioned and fixed at both ends of the CIS 32 as shown in FIG. Each roller unit 238 includes a frame 240 and a roller 241 supported by the frame 240. The frame 240 pivotally supports a pair of rollers 241 in a state where the roller 241 can roll in the short direction of the CIS 32. Each roller 241 protrudes upward uniformly from the upper surface 227 of the CIS 32, and these rollers 241 come into contact with the back surface of the platen glass 31. Thereby, a certain gap is formed between the upper surface 227 of the CIS 32 and the rear surface of the platen glass 31. Due to this constant gap, the focal length of the CIS 32 coincides with the upper surface of the platen glass 31. That is, the roller 241 of the roller unit 238 protrudes upward from the upper surface 227 so that the focal length of the CIS 32 matches the upper surface of the platen glass 31. Further, the rolling of each roller 241 makes the movement of the CIS 32 relative to the platen glass 31 smooth.

  A spring receiving portion (not shown) is provided on the inner surface side of the bottom portion of the carriage 224, and a coil spring is held by the spring receiving portion. The coil spring is positioned by a spring receiving portion and is interposed between the CIS 32 and the carriage 224. By this coil spring, the CIS 32 mounted on the carriage 224 is urged toward the platen glass 31, that is, upward. The CIS 32 can move up and down within a predetermined range with respect to the carriage 224 by fitting the fitting portion 231 and the bearing portion 234 so as to move up and down within a predetermined range. Further, the rollers 241 of the roller unit 238 protruding from the upper surface 227 of the CIS 32 are pressed against the back surface of the platen glass 31 by the coil spring, and the CIS 32 can move downward against the urging force of the coil spring.

  A cable holding portion 202 is provided on the wall 237 of the carriage 224 on the side where the connector portion 201 is disposed. The cable holding portion 202 has a hook shape formed on the outer surface of the wall 237 and can lock the flat cable 40. This prevents one end of the flat cable 40 from being detached from the connector portion 201 due to the reciprocation of the CIS 32.

  When a document is placed on the platen glass 31 and a reading start command is input based on a predetermined operation on the operation panel 6, the CIS 32 is scanned on the document to read an image. The CIS 32 is mounted on a carriage 224, and the carriage 224 is moved in parallel with the platen glass 31 under the driving of a belt driving mechanism 226 (see FIG. 4). That is, the CIS 32 is moved in parallel with the platen glass 31 together with the carriage 224. The CIS 32 mounted on the carriage 224 is urged against the platen glass 31 by a coil spring. The CIS 32 is provided with a roller unit 238, and each roller 241 of the roller unit 238 comes into contact with the back surface of the platen glass 31 by receiving the biasing force of the coil spring. Thereby, the gap between the platen glass 31 and the CIS 32 is kept constant. The CIS 32 reads an image on the reading line in the main scanning direction through the platen glass 31, and is slid in the sub scanning direction.

  The flat cable 40 has flexibility, and follows the CIS 32 while changing its posture as the CIS 32 reciprocates. A fixing portion 33 is provided in the housing of the apparatus main body 10. The flat cable 40 changes its posture following the CIS 32 while being bent so that one end side thereof, that is, a portion from one end connected to the connector portion 201 to the fixing portion 33 is inverted into a U shape. The flat cable 40 is fixed to the apparatus main body 10 from the portion fixed to the fixing portion 33 to the other end connected to the control board 18.

  In this embodiment, since the scanner unit 3 is realized as an FBS, the CIS 32 is adopted as an image sensor. However, it is needless to say that a CCD image sensor (Charge Coupled Device Image Sensor) may be adopted. . Moreover, in this embodiment, although ADF (Auto Document Feeder) is not provided, this may be mounted. Furthermore, in this embodiment, the scanner unit 3 functions as an FBS, but it may be of a sheet feeder type.
