A structure capable of performing is disclosed.

JP 2003-258388 A

  However, when the first casing and the second casing are changed from the opened state to the closed state, the FPC is in a loosened state from a tightened state with respect to the hinge portion. When the winding state is loosened, the FPC has a larger winding diameter and bulges outward with respect to the hinge, and the swollen part can protrude into the closed casing of the first casing and the second casing. There is sex. For example, when storing a container such as printing paper and transporting the container in the housing, if the container contacts a portion protruding into the housing of the FPC, the FPC is rubbed by the container and breaks or breaks. It could happen.

  An object of the present invention is to provide an electronic device that can be pressed and protected so as not to protrude into the casing even when the flexible printed circuit board is loosened when the first casing and the second casing are opened and closed.

  According to one aspect of the present invention, the first opening is formed, and the first housing that houses the first circuit portion on which the electronic component is mounted and the housing that holds the second circuit portion on which the electronic component is mounted. A closed position that rotates relative to the first housing around a predetermined rotation axis, closes the first opening, and an open position that opens the first opening. A wiring board that is flexible and electrically connects the first circuit part and the second circuit part, and an inner surface of the first casing; A first edge that is wired along an inner surface of the second casing and that is closest to the position of the pivot shaft among the edges of the first opening of the first casing; A flexible pre wired between the edge of the housing and the second edge closest to the position of the pivot shaft across the crossing direction intersecting the axial direction of the pivot shaft. And when the second housing is in the closed position, the pivot shaft, the first edge portion, and the first edge portion are provided. A first gap and a second gap for wiring the flexible printed circuit board between the two edges and the inner surface of the first housing and the inner surface of the second housing, respectively. An electronic device including a first protrusion to be formed is provided.

  When the second casing is in the open position, the first protrusion forms a second gap with the inner surface of the second casing, and a flexible printed circuit board (hereinafter referred to as “FPC”) is placed in the second gap. Wiring to. When the second housing moves from the open position to the closed position, the first protrusion can further form a first gap with the inner surface of the first housing, and the FPC can be wired. Therefore, the first projecting portion suppresses the bulge generated by the loosening of the FPC when the first housing and the second housing move from the open position to the closed position, and prevents the FPC from protruding into the housing. be able to. For example, even when storing a container such as printing paper and transporting the container in the housing, the FPC can be protected by the first protrusion so that the container does not rub against the container. The electronic device can prevent disconnection of the FPC.

  This aspect may further include a pressing portion that is provided in the first housing and forms a third gap for wiring the flexible printed circuit board between the inner surface of the first housing. In this case, the tip end portion of the first projecting portion is a third edge portion that is an edge portion on the second housing side in the intersecting direction of the pressing portion when the second housing body is in the closed position. May be arranged at a position facing each other. In the process in which the second housing moves from the open position to the closed position, the first protruding portion performs wiring in the first gap after pressing the FPC and wiring in the second gap. In this process, the first gap gradually narrows from the base end side to the tip end side of the first projecting portion, so that the portion where the FPC swells may shift to the tip end side of the first projecting portion. is there. The pressing portion holds the FPC so that the FPC does not swell into the casing from the inner surface of the first casing. Therefore, even if the site where the FPC swells shifts toward the tip end side of the first protrusion, the pressing part can suppress the swell of the FPC and protect the FPC from contact with the contents. By the way, when there is no holding | suppressing part, in order to ensure that FPC does not protrude in a housing | casing, it is necessary to make the 1st protrusion part protrude long from the 2nd housing | casing to the 1st housing | casing side. In the first aspect, by providing the pressing portion in addition to the first protruding portion, the bulge of the FPC can be shared and pressed by the first protruding portion and the pressing portion. Therefore, the length which the 1st protrusion part protrudes from the 2nd housing | casing can be shortened.

  In this aspect, the first protrusion may include a second protrusion that protrudes toward at least one of the first gap and the second gap. In the process in which the second housing moves from the open position to the closed position, the second protrusion can start to push the FPC toward the inner surface of the first housing at an earlier stage than when the second housing enters the closed position. Therefore, when it becomes a closed position, the 1st protrusion part can make it difficult to protrude FPC in a housing | casing from a front-end | tip part, and can protect FPC. Therefore, the electronic device can prevent disconnection of the FPC. In addition, when the pressing portion is provided in the first housing, it is possible to prevent the FPC from being sandwiched between the distal end portion of the first protruding portion and the third edge portion of the pressing portion.

  In this aspect, the second protruding portion may be provided in a portion of the first protruding portion that is closer to a portion that straddles the rotation axis than a tip portion of the first protruding portion. By providing the second protrusion at a position closer to the rotation axis than the tip of the first protrusion, it is even faster in the process of moving the first housing and the second housing from the open position to the closed position. From the stage, the second protrusion can begin to push the FPC closer to the inner surface of the first housing and within the first gap. Therefore, when it is in the closed position, the FPC does not protrude from the tip of the first protrusion, and the FPC is securely protected by the first protrusion and the holding part so that it is not scraped into the contents. Disconnection or the like can be prevented.

  In this aspect, the pressing portion is a portion protruding in parallel with the axial direction from the inner surface of the first casing, and may be provided integrally with the first casing. By providing the pressing portion integrally with the first housing, it is possible to reduce the trouble of attaching the pressing portion to the first housing when provided separately, and to further reduce the number of parts.

  In this aspect, a second opening may be formed in the second housing. The second housing is fixed to the inner surface of the second housing so as to cover the second opening, and when the second housing is in the closed position, the second housing from the outside of the second housing You may further provide the cover body which can visually recognize the inside of two opening part. The first protrusion may be provided integrally with the cover body. Since the first projecting portion is configured integrally with the cover body, it is possible to reduce the trouble in attaching the first projecting portion to the second housing separately from the cover body, and further reduce the number of parts.

  In this aspect, the electronic device includes: a printing unit that prints on a label; a first housing that houses a holding unit that holds a roll on which a mount on which the label is attached is wound; and the rotation shaft. A printing apparatus provided with the second casing that moves relative to the first casing by rotating to the center and exposes and stores the holding section by opening and closing the first opening; There may be. By applying the configuration of the electronic device according to any one of claims 1 to 6 as a configuration of a printing apparatus that prints on a label, an FPC wired between the first housing and the second housing is a printing unit. It is possible to prevent the possibility of contact with the board to be conveyed and scraping.

  As shown in FIGS. 2 and 4, the housing 2 includes a pressing portion 78 in the accommodating portion 24. Of the pair of ribs 24D that support the pair of bearing portions 24A provided on the edge 24C of the accommodating portion 24, the pressing portion 78 is provided in a plate shape that protrudes rightward from the right rib 24D. The pressing portion 78 protrudes with a length at least equal to the width of the FPC 11. As shown in FIG. 5, the pressing portion 78 forms a third gap D <b> 3 between the holding portion 24 and the inner surface 24 </ b> F. As shown in FIG. 7, when the rear cover 3 is moved to the closed position, the size of the third gap D <b> 3 of the pressing portion 78 is the same as the first protrusion 75 formed between the inner surface 24 </ b> F of the housing portion 24. The size of the gap D1 is substantially the same. Further, when the rear cover 3 is moved to the closed position, the front end portion 75 </ b> A of the first projecting portion 75 is disposed at a position facing the upper edge portion 78 </ b> A of the pressing portion 78. That is, when the rear cover 3 is moved to the closed position, the first projecting portion 75 and the pressing portion 78 are disposed between the first gap D1 and the second gap between the inner surface 34F of the top wall portion 34 and the inner surface 24F of the accommodating portion 24. A space having a gap D2 and a third gap D3 is formed. The FPC 11 is accommodated in this space.

  An outline of a case where printing on a thermal label is performed in the printing apparatus 1 having such a configuration will be described. When the lever 23 of the housing 2 moves downward according to the operation, the hook 27 swings and the engagement with the support cylinder 33 that supports the platen roller 32 is released. The rear cover 3 swings the free end upward by the biasing force of the biasing member 29A, and opens the opening 24B of the housing portion 24. With the roll-shaped label tape attached to the holder 9, the rear cover 3 moves to the closed position with the edge of the label tape drawn from the roll-shaped label tape extending above the cutting portion 26A. Then, the opening 24B of the accommodating portion 24 is closed. The hook 27 engages with the support cylinder 33, and the platen roller 32 is positioned with respect to the printing unit 26 </ b> B of the housing 2. The label tape is inserted between the printing unit 26B and the platen roller 32 from below to above. The printing unit 26B is pressed by an urging member (not shown) and presses the label tape against the platen roller 32 with a predetermined force.

  When the CPU (not shown) of the control board 8 receives the print data, the CPU controls the drive of the drive unit (not shown) and rotates the platen roller 32 via the gear 37. The label tape sandwiched between the platen roller 32 and the printing unit 26B is sequentially fed out and conveyed from below to above. At the same time, the CPU controls the driving of the heating elements of the printing unit 26B and generates heat according to the print data. As a result, characters and figures are printed on the thermal label. After printing, the label tape is discharged to the outside of the printing apparatus 1 with the thermal label attached to the mount. The discharged label tape is cut by the cutting unit 26A.

  By the way, as described above, the FPC 11 that electrically connects the control board 8 and the detector 10 includes the inner surface 24F of the housing portion 24 of the housing 2 and the inner surface 34F of the top wall portion 34 of the rear cover 3. It is wired along. More specifically, as shown in FIGS. 2 and 5, the FPC 11 passes through a position closer to the right end in the accommodating portion 24 from the end portion on the control board 8 side, and the third portion formed by the pressing portion 78 and the inner surface 24F. A route passing through the gap D3 is wired. In addition, the part wired along the inner surface 24F of the accommodating part 24 in the front side rather than the press part 78 of FPC11 is being fixed to the inner surface 24F, for example with the double-sided tape. The FPC 11 wired in the third gap D3 straddles the edge portion 24C of the accommodating portion 24 in the crossing direction. When the rear cover 3 is in the open position, the edge portion 34 </ b> C of the top wall portion 34 is located in front of the position of the shaft rod 29 and projects into the accommodating portion 24. The first projecting portion 75 is also located in front of the shaft rod 29 and projects into the housing portion 24. The FPC 11 straddles the edge 34C in the crossing direction, passes through the gap between the tip 76A of the second protrusion 76 and the inner surface 34F of the top wall 34, and is further formed by the first protrusion 75 and the inner surface 34F. A route passing through the two gaps D2 is wired. Therefore, the FPC 11 is wired in a path that passes through the inside of the housing portion 24 rather than the position of the shaft rod 29. Within the second gap D2, the FPC 11 is wired along a path in which the shaft rod 29 is disposed on the inner surface 34F side. The FPC 11 wired in the second gap D2 passes between the extension 72 and the inner surface 34F, and is wired along the inner surface 34F. In addition, as for FPC11, the part which passes between the extension part 72 and the inner surface 34F is being fixed to the inner surface 34F with the double-sided tape, for example. The FPC 11 wired between the extension 72 and the inner surface 34 </ b> F is connected to the detector 10 at the end opposite to the control board 8.

  As described above, the FPC 11 is not fixed at a portion from the second gap D2 to the third gap D3 in the route wired in the printing apparatus 1. Further, since the FPC 11 straddles the edge 34C protruding into the accommodating portion 24, the length of the portion from the second gap D2 to the third gap D3 when the rear cover 3 is in the open position (see FIG. 5) is large. The distance between the second gap D2 and the third gap D3 when the rear cover 3 is in the closed position (see FIG. 7) is longer. Therefore, as shown in FIG. 6, when the rear cover 3 is in an intermediate position where the rear cover 3 is moved from the open position to the closed position, the FPC 11 is loosened. Similarly, the second protrusion 76 provided on the first protrusion 75 located on the front side of the shaft rod 29 in the open position is located on the front side of the shaft rod 29. In the process in which the rear cover 3 moves to the closed position, the second protrusion 76 moves the distal end 76A rearward.

  In the process in which the rear cover 3 moves to the closed position, the FPC 11 moves to the distal end portion 76A of the second projecting portion 76 projecting into the second gap D2 before contacting the distal end portion 75A of the first projecting portion 75. Abut. The second protrusion 76 presses the FPC 11 backward. Since the FPC 11 is pressed against the second protrusion 76 from an early stage as compared with the case where the first protrusion 75 does not include the second protrusion 76, the loosened portion is pressed against the second protrusion 76, It is suppressed that the bulge which arises protrudes largely in the accommodating part 24. FIG. And since FPC11 produces the curvature which swells to the back side by the press of the 2nd protrusion part 76, in the site | part between the 2nd protrusion part 76 and the 3rd gap | interval D3, 2 bending | flexion which bends FPC11 in S shape. Formation of the parts C1, C2 is induced. The FPC 11 is further pressed rearward by the second protrusion 76 and moved rearward so as to be folded at the bent portions C1 and C2. When the FPC 11 comes into contact with the first protrusion 75, the FPC 11 is also pressed rearward directly by the first protrusion 75.

  As shown in FIG. 7, when the rear cover 3 moves to the closed position, the FPC 11 is pushed into the first gap D <b> 1 and is accommodated in the space formed by the first protrusion 75 and the presser 78. The FPC 11 is wired in the third gap D3 formed by the pressing portion 78 and the inner surface 24F of the accommodating portion 24, and thus the bulge is generated at the position of the pressing portion 78 in the process of moving the rear cover 3 to the closed position. Is suppressed. In addition, when the portion where the FPC 11 swells shifts to the tip end 75A side of the first projecting portion 75 in the process of moving the rear cover 3 to the closed position, the pressing portion 78 is positioned on the shifting side. The bulge of the FPC 11 can be suppressed. And by arrange | positioning the 1st protrusion part 75 and the press part 78 between the label tapes accommodated in the accommodating part 24, FPC11 is protected by the 1st protrusion part 75 and the press part 78, and is roll shape. There is no contact with the label tape. Further, the FPC 11 is folded by the formation of the bent portions C1 and C2, so that the FPC 11 is prevented from being caught in the gap between the distal end portion 75A of the first projecting portion 75 and the edge portion 78A of the pressing portion 78.

  As described above, when the rear cover 3 is in the open position, the first protrusion 75 forms the second gap D2 with the inner surface 34F of the top wall 34 of the rear cover 3, and the FPC 11 is moved to the second gap. Wire in D2. When the rear cover 3 moves from the open position to the closed position, the first projecting portion 75 further forms a first gap D1 between the inner surface 24F of the housing portion 24 of the housing 2 and the FPC 11 can be wired. it can. Therefore, the first projecting portion 75 suppresses the swelling generated by the loosening of the FPC 11 when the housing 2 and the rear cover 3 move from the open position to the closed position, so that the FPC 11 does not protrude into the housing portion 24. can do. When transporting the label tape stored in the storage unit 24, the FPC 11 can be protected by the first projecting portion 75 so as not to be rubbed by the label tape, so that the electronic device can prevent disconnection of the FPC 11 and the like. Can do.

  In the process in which the rear cover 3 moves from the open position to the closed position, the first protrusion 75 holds the FPC 11 and wires it in the second gap D2, and then wires it in the first gap D1. In this process, since the first gap D1 is gradually narrowed from the base end 75B side to the tip end 75A side of the first projecting portion 75, the bulging portion of the FPC 11 is the tip end 75A side of the first projecting portion 75. May shift to The pressing portion 78 presses the FPC 11 so that the FPC 11 does not swell into the accommodating portion 24 from the inner surface 24F of the accommodating portion 24 of the housing 2. Therefore, even if the part where the FPC 11 swells shifts to the tip 75A side of the first protrusion 75, the pressing part 78 can suppress the swell of the FPC 11 and protect the FPC 11 from contact with the label tape. By the way, when there is no pressing part 78, in order to ensure that FPC11 does not protrude in a housing | casing, it is necessary to make the 1st protrusion part 75 protrude long from the rear cover 3 to the housing | casing 2 side. In the present embodiment, by providing the pressing portion 78 in addition to the first protruding portion 75, the swelling of the FPC 11 can be shared and pressed by the first protruding portion 75 and the pressing portion 78. Therefore, the length by which the first protrusion 75 protrudes from the rear cover 3 can be shortened.

  In the process in which the rear cover 3 moves from the open position to the closed position, the second projecting portion 76 can start pushing the FPC 11 toward the inner surface 24F of the housing portion 24 at an earlier stage than when the rear cover 3 is moved to the closed position. Therefore, when it becomes a closed position, the 1st protrusion part 75 can make it difficult to protrude FPC11 in the accommodating part 24 from 75 A of front-end | tip parts, and can protect FPC11. Therefore, the printing apparatus 1 can prevent the FPC 11 from being disconnected. Further, by starting to push the FPC 11 toward the inner surface 24F at an early stage by the second projecting portion 76, the FPC 11 is sandwiched between the tip portion 75A of the first projecting portion 75 and the edge portion 78A of the pressing portion 78. Can be prevented.

  In the process in which the housing 2 and the rear cover 3 are moved from the open position to the closed position by providing the second protrusion 76 at a position closer to the shaft rod 29 than the tip 75A of the first protrusion 75, From the early stage, the second projecting portion 76 can start to bring the FPC 11 closer to the inner surface 24F of the accommodating portion 24 and push it so as to be within the first gap D1. Therefore, when it is in the closed position, the FPC 11 does not protrude from the tip 75A of the first protrusion 75, and the FPC 11 is securely protected by the first protrusion 75 and the pressing part 78 and scraped into the label tape. It is possible to prevent disconnection and the like.

  The pressing portion 78 is formed on the rib 24D standing on the inner surface 24F of the accommodating portion 24, and is provided integrally with the housing 2, thereby reducing the trouble of attaching the pressing portion 78 to the housing 2 when provided separately. In addition, the number of parts can be reduced. In addition, since the first projecting portion 75 is integrally formed with the transmissive cover 7, it is possible to reduce time and effort when attaching the first projecting portion 75 to the rear cover 3 separately from the transmissive cover 7, and further reduce the number of parts. Can do.

  In addition, this invention is not limited to the said embodiment, A various change is possible. Although the first protrusion 75 includes the second protrusion 76 that protrudes into the second gap D2, the second protrusion 76 may not be provided. Further, the second projecting portion 76 may be provided at the distal end portion 75 </ b> A of the first projecting portion 75. The length by which the first protruding portion 75 protrudes may be longer than in the present embodiment, and the pressing portion 78 may be shortened or eliminated. Alternatively, the protruding length of the first protruding portion 75 may be shorter than that of the present embodiment, and the edge portion 78A of the pressing portion 78 may be brought closer to the edge of the edge portion 24C of the accommodating portion 24. The lateral width of the first protrusion 75 may be smaller or larger than the FPC 11.
