[0020] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. It should be noted that the size, material, shape and relative arrangement of the components described in the embodiments may be appropriately changed according to the configuration of the device to which the present invention is applied, various conditions, etc., and are not intended to limit the scope of the present invention to the following embodiments.

[0021] First embodiment

[0022] Recording device

[0023] A recording device according to a first embodiment will be described below with reference to the accompanying drawings. In the recording device, a scanner portion 2 for performing image scanning is coupled to an upper portion of a main body portion 1 for performing image recording in such a manner that the scanner portion 2 can be opened and closed. A user can move the scanner portion 2 to an open position for opening the main body portion 1 and a closed position for closing the main body portion 1. Figure 1 is a perspective view of the recording device when the scanner portion 2 is in the closed position. Figure 2 is a perspective view of the recording device when the scanner portion 2 is in the open position. Figure 3 is a perspective view of the interior of the lower housing 8 when the scanner portion 2 is in the closed position. Figure 4 : is a perspective view of the inside of the lower housing 8 when the scanner section 2 is in the open position. In the figure, arrow X indicates the X axis, arrow Y indicates the Y axis, and arrow Z indicates the Z axis. The moving direction of the carriage 4 is parallel to the X direction, and the sheet conveying direction is parallel to the Y direction. The XY plane defined by the X direction and the Y direction is a horizontal plane, the Z direction perpendicular to the horizontal plane is a vertical direction, and it is assumed that the recording device is set on the horizontal plane.

[0024] In the main body 1, the lower shell 8 including the outer panel accommodates the recording part for recording images and the conveying part for conveying sheets. The outer panel of the lower shell 8 is composed of the front side on which the operation panel 31 is configured, the rear side opposite to the front side, the two side surfaces connecting the front side and the rear side, and the bottom side. In the present embodiment, the side surfaces can be represented as the left side and the right side relative to the front side. The operation panel 31 includes a button for operating the recording device and a display for displaying the state of the recording device. An output port 32 for outputting the recorded sheet is configured below the operation panel 31. A tray 33 for stacking the sheet to be recorded on the image is configured below the output port 32, and is inserted into the lower shell 8 and pulled out from the lower shell 8. The recording device can be constructed to have a pull-out output tray between the output port 32 and the tray 33. A power supply 9 for supplying DC current to the recording device is configured adjacent to the outer panel on the rear side and adjacent to the outer panel on the left side in the main body 1. A connector 34 for communicating with an external device is configured on the outer panel above and on the left side of the power supply 9.

[0025] The scanner portion 2 includes a scanning sensor for scanning a document placed on the document table. The scanner portion 2 can be opened and closed around a hinge provided on the upper portion of the rear side of the main body portion 1. In other words, the scanner portion 2 acts as a cover for closing the lower housing 8 accommodating the recording portion, the conveying portion, etc. When the scanner portion 2 is in the closed position, image recording and document scanning can be performed. The recording device can be constructed to have a cover without the scanner portion 2. The scanner portion 2 can have a conveying mechanism for conveying the document.

[0026] When the opening and closing of the scanner part 2 is manually performed by the user, it is controlled by the opening / closing mechanism. The opening / closing mechanism can hold the scanner part 2 in the open position, release the holding to move the scanner part 2 to the closed position, and maintain the closed position. The opening / closing mechanism includes a bracket 5 that can be swingably supported by the scanner part 2 and a track mechanism 6 provided in the main body part 1. The protruding end 5a of the bracket 5 is coupled to the track mechanism 6 and can move along the groove of the track mechanism 6.

[0027] The recording part includes a platen for supporting the conveyed sheet, a recording unit 3 facing the platen and recording an image on the sheet, and a carriage 4 for moving the recording unit 3. The carriage 4 on which the recording unit 3 is mounted can reciprocate along the X direction (i.e., the moving direction). The carriage 4 is driven by a drive motor, a belt, a pulley, etc. (not shown). The conveying part includes a conveying roller 10 and an output roller 11, which convey the sheet supplied from the tray 33 along the conveying direction. In the present embodiment, the conveying direction and the moving direction intersect and are perpendicular to each other. The sheet can be supplied from a sheet feeder provided on the upper part of the outer panel on the rear side.

[0028] Here, the recording of the image will be described. The recording operation of the image consists of a sheet conveying operation and an ink ejecting operation. The image to be recorded is obtained from an external device connected to the connector 34 or from the scanner part 2. In the conveying operation, the conveying roller 10 conveys the sheet supplied from the tray 33 a predetermined distance along the conveying direction (-Y direction). Next, in the ejecting operation, the recording unit 3 moves while ejecting ink from the nozzle 23. While the conveying operation and the ejecting operation are alternately performed, the image is recorded on the sheet. The output roller 11 outputs the sheet with the image recorded thereon from the output port 32. The conveying roller 10 is coupled to the conveying roller gear 12, and the output roller 11 is coupled to the output roller gear 14. The conveying roller 10 and the output roller 11 are driven by a conveying motor (not shown).

[0029] Figure 5A and Figure 5B The carriage 4 on which the recording unit 3 is mounted is shown. Figure 5A : is a top view of the carriage 4. The carriage 4 reciprocates between the starting position and the turning position. The two-dot chain line represents the carriage 4 in the starting position, and the solid line represents the carriage 4 in the turning position. Figure 5B: is a schematic perspective view of the carriage 4. The dotted line indicates the recording unit 3 mounted on the carriage 4. The carriage 4 can be mounted with the recording unit 3a and the recording unit 3b, in other words, a plurality of recording units 3. The recording unit 3 includes an ink tank for containing ink and a nozzle 23 for ejecting ink. The ink is, for example, black ink, cyan ink, magenta ink, or yellow ink. When the ink is exhausted, the user can remove the recording unit 3 from the carriage 4 / attach the recording unit 3 to the carriage 4. The recording unit 3 is mounted on the carriage 4 in such a manner that the nozzle 23 faces the sheet. The recording unit 3 may be configured to supply ink through a tube.

[0030] The lower case 8 includes a frame 17 that supports the movement of the carriage 4. The carriage 4 can reciprocate between a starting position and a turning position due to the guide portion 7 of the frame 17. The support portion 4a of the carriage 4 protrudes to the starting position side and the turning position side relative to the recording unit 3 in the moving direction of the carriage 4. The support portion 4a has a sliding surface 24a that slides on the guide surface of the guide portion 7. The guide portion 7 is provided on the frame 17. The frame 17 is formed by bending a metal plate and fixing it to the lower case 8. Figure 5A In the embodiment, the guide portion 7 is a flat rail divided into an upper rail and a lower rail. Therefore, in this case, the guide surface is a flat surface. The support portion 4a may be formed integrally with the portion holding the recording unit 3 or may be formed separately.

[0031] exist Figure 5B In the framework 17, Figure 5A The guide portions 7 of the upper rail and the lower rail in the slide 4 are simplified into two shafts having circular cross sections, respectively. The support portion 4a of the carriage 4 is simplified into a rectangle and protrudes to both sides relative to the recording unit 3 in the moving direction of the carriage 4. The carriage 4 has a sliding surface 24a and a sliding surface 24b in the lower and upper parts that slide on the guide portions 7a and 7b, respectively. In this case, the guide surface may be a curved surface. The sliding surface 24a and the sliding surface 24b are provided on both sides relative to the recording unit 3 in the moving direction of the carriage 4. Since the sliding surfaces 24a and 24b are in contact with the guide surfaces of the guide portions 7a and 7b, respectively, the recording unit 3 can reciprocate in the X direction while maintaining its posture.

[0032] FIG. 6A to FIG. 6C is a perspective view illustrating the carriage 4 and the recording unit 3 . Fig. 6A The figure shows the carriage 4 without the recording unit 3 mounted thereon. Figure 6B The diagram shows a carriage 4 on which a recording unit 3 is mounted, and Figure 6C Two recording units 3 are shown. FIG. 7A to FIG. 7C It is a bottom view of the carriage 4 and the recording unit 3. Fig. 7A The figure shows the carriage 4 without the recording unit 3 mounted thereon. Figure 7B The diagram shows a carriage 4 on which a recording unit 3 is mounted, and Figure 7CTwo recording units 3 are shown. The sliding surface 24a on the lower side of the carriage 4 is arranged on both sides relative to the recording unit 3 in the moving direction of the carriage 4, and the sliding surface 24b on the upper side of the carriage 4 is arranged at a position close to the center. The length of the recording unit 3 in the conveying direction is greater than the width of the recording unit 3 in the moving direction. Therefore, even if the width of the recording unit 3 is small, the ink tank can still hold enough ink. The distance L1 between the two sliding surfaces 24a of the carriage 4 is greater than the width L5 of the two recording units 3. For example, L1 can be greater than 1.5 times of L5. In other words, at the time of acceleration and deceleration, the carriage 4 is affected by the rotational force around the conveying direction. When the distance between the sliding surfaces 24a on both sides in the moving direction is sufficiently greater than the width of the recording unit 3 in the moving direction, the influence of the rotational force is reduced and the movement of the carriage 4 becomes stable. Since the distance between the sliding surfaces 24a on both sides is greater than the width of the recording unit 3, a space of length L3 is generated on the steering position side, and the opening / closing mechanism is not easy to interfere with the carriage 4. The length L3 of the space on the turning position side may be greater than the length L4 of the space on the starting position side.

[0033] Figures 8 to 10 An opening / closing mechanism that controls the opening and closing of the scanner portion 2 is illustrated. Figure 8 The opening / closing mechanism is illustrated when the scanner portion 2 is in the closed position. Fig. 9 The opening / closing mechanism is shown when the scanner portion 2 is in the open position. Fig.10 The track mechanism 6 is shown. Figure 8 and Fig. 9 In FIG. 1 , a schematic diagram of the recording unit 3, the carriage 4, and the guide 7 is indicated by two-dot chain lines. The opening / closing mechanism includes a bracket 5 and a rail mechanism 6. The rail mechanism 6 is arranged with respect to the outer panel on the left side adjacent to the bracket 5. One end of the bracket 5 can be swingably supported by the scanner portion 2, and the other end includes a protruding end portion 5a. The protruding end portion 5a can move along the groove of the rail mechanism 6. Fig. 9 , the bracket 5 is pushed counterclockwise (towards the outer panel on the back side) relative to the scanner part 2.

[0034] The track mechanism 6 includes an inclined portion 6c that gets closer to the output port 32 as the distance from the bottom surface of the main body portion 1 decreases; an annular portion 6d that guides the protruding end 5a in a ring shape; and a baffle 6a that determines the moving path of the protruding end 5a. The end 6e of the track mechanism 6 is below the frame 17. When the scanner portion 2 is in the closed position, the protruding end 5a of the bracket 5 is located at a position 5a-1 close to the end 6e of the track mechanism 6. When the scanner portion 2 is opening, the protruding end 5a moves along the inclined portion 6c of the track mechanism 6, is guided by the baffle 6a, passes through the position 5a-2, and reaches the corner portion of the position 5a-3. Fig.10 , push the baffle 6a counterclockwise, and the protruding end 5a can move in the annular portion 6d in one direction. At position 5a-3, the movement of the protruding end 5a in the Z direction and the Y direction is limited by the corner portion of the track mechanism 6. Therefore, the scanner part 2 cannot move in the opening direction. When the scanner part 2 moves from position 5a-3 in the closing direction, the protruding end 5a engages with the latch portion 6b at position 5a-4. Therefore, since the bracket 5 receives the weight of the scanner part 2 in a state where the bracket 5 is engaged with the latch portion 6b of the track mechanism 6, the bracket 5 can keep the scanner part 2 in the open position. When the scanner part 2 is in the open position, the user can perform maintenance on the inside of the main body part 1. Examples of maintenance include removal and attachment of the recording unit 3 and removal of sheets when a paper jam occurs.

[0035] Next, when the scanner part 2 maintained in the open state is moved in the opening direction, the protruding end 5a moves in the Y direction due to the counterclockwise pushing force and reaches the corner portion of the 5a-5 position. At the position 5a-5, the protruding end 5a is restricted by the corner portion of the track mechanism 6 and cannot move in the opening direction. When the protruding end 5a moves downward in a state restricted by the corner portion of the position 5a-5, the protruding end 5a moves along the groove of the track mechanism 6 and pushes the baffle 6a to open. The protruding end 5a is able to move downward from the position 5a-5 by the weight of the scanner part 2 or the user's operation. In addition, the protruding end 5a moves downward along the inclined portion 6c and reaches the position 5a-1.

[0036] When the protruding end 5a reaches the position 5a-1, the scanner part 2 becomes stable in the state where the scanner part 2 closes the lower shell 8. Therefore, the scanner part 2 and the main body part 1 return to a state that can be normally used. As an operation by the user, the user manually opens the scanner part 2 from the closed position until the scanner part 2 stops, and then releases the hand from the scanner part 2. When the protruding end 5a is engaged with the latch part 6b, the scanner part 2 remains in the open position. To return the scanner part 2 to the closed position, the user opens the scanner part 2 from the open position until the scanner part 2 stops, and then releases the hand or presses the scanner part 2 downward. Then, the scanner part 2 moves downward to the closed position due to its own weight. In this way, the opening / closing mechanism keeps the scanner part 2 in the open position, releases the open position, keeps the scanner part 2 in the closed position, and further controls the movement between the open position and the closed position.

[0037] Fig.11 The positional relationship between the opening / closing mechanism and the carriage 4 is illustrated. The turning position of the carriage 4 closest to the opening / closing mechanism in the sheet width direction is indicated by a solid line, and the starting position of the carriage 4 farthest from the opening / closing mechanism is indicated by a two-dot chain line. The turning position varies depending on the sheet width. Here, the case where the sheet width is the largest is illustrated. When viewed from the moving direction (X direction) of the carriage 4, the opening / closing mechanism overlaps at least the front part of the recording unit 3 in the area Ya. In other words, the area Ya is an area where the recording unit 3 and the opening / closing mechanism overlap when projected onto the Y axis. On the other hand, when viewed from the moving direction, the opening / closing mechanism does not overlap with the support portion 4a. When viewed from the conveying direction (Y direction), when the carriage 4 is at the turning position, the bracket 5 and the rail mechanism 6 overlap with the support portion 4a in the area Xa. In other words, the area Xa is an area where the carriage 4 and the opening / closing mechanism overlap when projected onto the X axis. With this configuration, the width of the recording device in the sheet width direction can be reduced. One of the bracket 5 or the rail mechanism 6 may be configured to overlap with the support portion 4 a .

[0038] If the opening / closing mechanism is arranged on the hinge side that does not overlap with the recording unit 3 in the conveying direction, the force acting on the components increases due to the lever action when the scanner section 2 is held in the open position. In this case, it is necessary to increase the strength of the bracket 5, the rail mechanism 6, and the scanner section 2. Therefore, it is necessary to reinforce the space, and the cost will also increase in order to increase the strength.

[0039] On the other hand, if the opening / closing mechanism is arranged at the front so that the opening / closing mechanism does not overlap with the recording unit 3 in the conveying direction, the stroke of the carriage 5 is insufficient and the opening angle of the scanner portion 2 is reduced. In this case, it is difficult to perform operations such as detachment and attachment of the recording unit 3, removal of sheets when a paper jam occurs, and the like.

[0040] Fig.12 The diagram shows the positional relationship between the carriage 4 and the drive mechanism of the conveying roller 10. The carriage 4 at the turning position is represented by a solid line, and the carriage at the starting position is represented by a two-dot chain line. The bracket 5 and the track mechanism 6 are represented by two-dot chain lines respectively. The guide portion 7, the conveying roller 10 and the output roller 11 are arranged downstream in the conveying direction. The drive mechanism is a mechanism that transmits the driving force from the conveying motor (not shown) to the conveying roller 10 and the output roller 11.

[0041] The driving mechanism includes a conveying roller gear 12, an output roller gear 14 and an intermediate gear. The conveying motor can convey the sheet downstream along the conveying direction by rotating the conveying roller 10 and the output roller 11 in the same direction. The conveying roller 10 and the output roller 11 are arranged parallel to the guide portion 7. The conveying roller gear 12 is arranged between the outer panel on the left side and the conveying roller 10, and transmits the driving force to the conveying roller 10. The code wheel 13 for measuring the rotation amount of the conveying roller 10 is coaxially arranged with the conveying roller 10. The sensor (not shown) measures the rotation amount of the conveying roller 10 by reading the code wheel 13. By measuring the rotation amount, the controller can control the sheet conveying distance and the sheet conveying speed. The code wheel 13 can be configured to overlap with the area Xa from the conveying direction, or can be configured not to overlap with the area Xa due to having a larger diameter. Similarly, the output roller gear 14 is arranged between the outer panel on the left side and the output roller 11, and transmits the driving force to the output roller 11. When viewed from the conveying direction, the conveying roller gear 12 and the output roller gear 14 are arranged at a position overlapping with the area Xa. Since a part of the driving mechanism is arranged at a position overlapping with the area Xa in this way, the width of the recording device can be reduced. In addition, the power supply 9 is arranged on the opening / closing mechanism side of the recording device and at a position between the frame 17 and the rear side outer panel. When viewed from the conveying direction, a part of the power supply 9 overlaps with the area Xa.

[0042] Fig.13The diagram illustrates the configuration of the cable 26 connecting the operation panel 31 and the control board 28. The control board 28 is configured along the frame 17 on a side of the frame 17 close to the outer panel on the back. A connector 34 may be configured on the control board 28. The control board 28 can communicate with an external device via the connector 34. The cable 26 is a flexible flat cable (FFC) and connects the control board 28 and the operation panel 31. The cable 26 is wired in a space between the outer panel on the left side and the track mechanism 6. On the reverse side of the annular portion 6d of the track mechanism 6, the track mechanism 6 has a holding portion that can hold the cable 26. A ferrite core 27 that reduces noise from the cable 26 is configured on the cable 26. The ferrite core 27 is held from an extension portion of the track mechanism 6.

[0043] As described above, the opening / closing mechanism is arranged at a position overlapping with the recording unit 3 as viewed in the moving direction of the carriage 4 , and at a position overlapping with the supporting portion 4 a as viewed in the sheet conveying direction.

[0044] With this configuration, the width of the recording device can be reduced. In addition, a sufficient opening angle of the scanner portion 2 can be achieved.

[0045] Second embodiment

[0046] Fig.14 The opening / closing mechanism of the scanner part 2 according to the second embodiment is illustrated. The recording unit 3, the carriage 4, and the guide portion 7 are indicated by two-dot chain lines. In the second embodiment, the bracket 5 and the rail mechanism 6 of the opening / closing mechanism are replaced by using components of other methods. The configuration of these is similar to that in the first embodiment. In other words, the opening / closing mechanism is configured at a position overlapping with the front of the recording unit 3 as viewed from the moving direction of the carriage 4, and the opening / closing mechanism is configured at a position overlapping with the support portion 4a as viewed from the sheet conveying direction.

[0047] In the opening / closing mechanism, a bracket 51 having a sector gear is provided on the scanner portion 2 and is coupled to a gear mechanism 61 provided in the main body portion 1. The gear mechanism 61 includes a coupling gear of the first stage, a braking unit of the last stage, and an intermediate gear. As the coupling gear of the first stage moves a short distance in the swinging direction of the bracket 51, when the scanner portion 2 moves in the closing direction, the drive is transmitted to the braking unit of the last stage. On the other hand, when the scanner portion 2 moves in the opening direction, the coupling gear of the first stage moves approximately a short distance upward, and the drive transmission is interrupted. With this construction, the rotation of the scanner portion 2 can be braked only in the closing direction. The scanner portion 2 is of a free stop type that can maintain its posture at any position between the open position and the closed position.

[0048] The brake unit of the last stage may be replaced with a damper unit and used together with the opening / closing mechanism of the scanner portion 2 of the first embodiment. In this case, the rotation of the scanner portion 2 in the closing direction may be decelerated to reduce the moving speed.

[0049] As described above, the width of the recording apparatus can be reduced, and a sufficient opening angle of the scanner portion 2 can be achieved.
