[0008] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. However, the dimensions, materials, shapes, and relative positions of the components described in the embodiment may be changed as appropriate depending on the configuration of the device to which the invention is applied and various conditions, and the scope of the present invention is not limited to the following embodiment.

[0009] [First embodiment] <Recording device> A recording device according to a first embodiment will be described with reference to the drawings. In the recording device, a scanner unit 2 for reading an image is connected to the upper part of a main body unit 1 for recording an image so as to be openable and closable. The scanner unit 2 can be moved by a user between an open position for opening the main body unit 1 and a closed position for closing it. FIG. 1 is a perspective view of the recording device with the scanner unit 2 in the closed position. FIG. 2 is a perspective view of the recording device with the scanner unit 2 in the open position. FIG. 3 is a perspective view showing the inside of a lower housing 8 with the scanner unit 2 in the closed position. FIG. 4 is a perspective view showing the inside of a lower housing 8 with the scanner unit 2 in the open position. In the drawings, the arrow X is the X axis, the arrow Y is the Y axis, and the arrow Z is the Z axis. The movement direction of the carriage 4 is parallel to the X direction, and the conveyance direction of the sheet is parallel to the Y direction. The XY plane defined by the X and Y directions is the horizontal plane, and the Z direction perpendicular to the horizontal plane is the vertical direction, and the recording device is installed on the horizontal plane.

[0010] The main body 1 houses a recording unit that records an image in a lower housing 8 including an exterior panel, and a conveying unit that conveys a sheet. The exterior panel of the lower housing 8 is composed of a front surface on which an operation panel 31 is arranged, a rear surface facing the front surface, two side surfaces connecting the front surface and a bottom surface. In this embodiment, the side surfaces may be expressed as the left and right sides with respect to the front surface. The operation panel 31 has buttons for operating the recording device and a display that displays the status of the recording device. An outlet 32 ​​for discharging recorded sheets is arranged below the operation panel 31. A tray 33 for stacking sheets on which an image is recorded is arranged below the outlet 32 ​​and is inserted and removed from the lower housing 8. The recording device may have a configuration in which a removable outlet tray is provided between the outlet 32 ​​and the tray 33. A power supply 9 for supplying DC current to the recording device is arranged on the left side exterior panel side on the rear exterior panel side of the main body 1. In addition, a connector 34 for communicating with an external device is arranged on the left side exterior panel above the power supply 9.

[0011] The scanner unit 2 has a reading sensor that reads a document placed on a document table. The scanner unit 2 can be opened and closed around a hinge provided at the top of the rear side of the main body unit 1. In other words, the scanner unit 2 plays the role of a cover that closes the lower housing 8 that houses the recording unit, transport unit, etc. When the scanner unit 2 is in the closed position, it is possible to record an image and read a document. Note that the recording device may have a cover that does not have the scanner unit 2. The scanner unit 2 may also have a transport mechanism that transports a document.

[0012] The opening and closing of the scanner unit 2 is controlled by an opening and closing mechanism while being manually operated by the user. The opening and closing mechanism can hold the scanner unit 2 in the open position, release the hold to move it to the closed position, and maintain the closed position. The opening and closing mechanism is composed of a stay 5 supported by the scanner unit 2 so as to be able to swing, and a rail mechanism 6 provided on the main body unit 1. A tip protrusion 5a of the stay 5 is connected to the rail mechanism 6 and can move along the groove of the rail mechanism 6.

[0013] The recording section has a platen that supports the transported sheet, a recording unit 3 that faces the platen and records an image on the sheet, and a carriage 4 that moves the recording unit 3. The carriage 4 is mounted with the recording unit 3 and can move back and forth in the X direction, which is the movement direction. The carriage 4 is driven by a drive motor, a belt, a pulley, etc. (not shown). The transport section has a transport roller 10 and a discharge roller 11 that transport the sheet supplied from the tray 33 in the transport direction. The transport direction and the movement direction intersect each other, and are perpendicular in this embodiment. The sheet may be supplied from a sheet feeder provided on the upper part of the exterior panel on the rear side.

[0014] Here, the recording of an image will be described. The recording operation of an image is composed of a sheet transport operation and an ink ejection operation. Image data to be recorded is acquired from an external device connected to the connector 34 or the scanner unit 2. In the transport operation, the transport roller 10 transports the sheet supplied from the tray 33 a predetermined amount in the transport direction (-Y direction). Next, in the ejection operation, the recording unit 3 moves while ejecting ink from the nozzle 23. An image is recorded on the sheet by alternately performing the transport operation and the ejection operation. The sheet on which the image has been recorded is discharged from the ejection port 32 by the ejection roller 11. The transport roller 10 is connected to a transport roller gear 12, and the ejection roller 11 is connected to an ejection roller gear 14. The transport roller 10 and the ejection roller 11 are driven by a transport motor (not shown).

[0015] FIG. 5 shows the carriage 4 carrying the recording unit 3. FIG. 5(a) is a top view of the carriage 4. The carriage 4 reciprocates between the start position and the reverse position. The two-dot chain line shows the carriage 4 at the start position, and the solid line shows the carriage 4 at the reverse position. FIG. 5(b) is a perspective view showing the carriage 4 in a schematic manner. The dotted line shows the recording unit 3 carried on the carriage 4. The carriage 4 can carry a plurality of recording units 3, namely, the recording unit 3a and the recording unit 3b. The recording unit 3 includes a tank that contains ink and a nozzle surface 23 that ejects ink. The ink is, for example, black, cyan, magenta, and yellow. When the ink runs out, the user can attach and detach the recording unit 3 from the carriage 4. The recording unit 3 is mounted on the carriage 4 so that the nozzle surface 23 faces the sheet. The recording unit 3 may be configured to supply ink through a tube.

[0016] The lower housing 8 has a frame 17 that supports the movement of the carriage 4. The carriage 4 can reciprocate between a start position and a reverse position by a guide portion 7 of the frame 17. The support portion 4a of the carriage 4 protrudes from the recording unit 3 on both sides of the start position side and the reverse position side in the movement direction of the carriage 4. The support portion 4a has a sliding surface 24a that slides against the guide surface of the guide portion 7. The guide portion 7 is provided on the frame 17. The frame 17 is made by bending a metal plate and is fixed to the lower housing 8. In FIG. 5(a), the guide portion 7 is a flat rail that is divided into upper and lower parts. Therefore, in this case, the guide surface is flat. The support portion 4a may be formed integrally with the part that holds the recording unit 3, or may be separated from it.

[0017] In FIG. 5(b), the guide portion 7 of the frame 17 is simplified to two shafts with circular cross sections, as opposed to the upper and lower rails in FIG. 5(a). The support portion 4a of the carriage 4 is simplified to a rectangle, and protrudes on both sides of the recording unit 3 in the moving direction of the carriage 4. The carriage 4 has upper and lower sliding surfaces 24a and 24b that slide on the guide portions 7a and 7b, respectively. In this case, the guide surfaces may be curved. The sliding surfaces 24a and 24b are disposed on both sides of the recording unit 3 in the moving direction of the carriage 4. The sliding surfaces 24a and 24b come into contact with the guide surfaces of the guide portions 7a and 7b, respectively, so that the recording unit 3 can move back and forth in the X direction while maintaining its posture.

[0018] FIG. 6 is a perspective view showing the carriage 4 and the recording unit 3. FIG. 6(a) shows a case where the recording unit 3 is not mounted, FIG. 6(b) shows a case where the recording unit 3 is mounted, and FIG. 6(c) shows two recording units 3. FIG. 7 is a bottom view of the carriage 4 and the recording unit 3. FIG. 7(a) shows the carriage 4 without the recording unit 3 mounted, FIG. 7(b) shows the carriage 4 with the recording unit 3 mounted, and FIG. 7(c) shows two recording units 3. The lower sliding surface 24a of the carriage 4 is arranged on both sides of the recording unit 3 in the moving direction of the carriage 4, and the upper sliding surface 24b is arranged at one location near the center. The length of the recording unit 3 in the transport direction is larger than the width in the moving direction. By doing so, the amount of ink that can be stored in the tank can be secured even if the recording unit 3 is thin. In addition, the distance L1 between the two sliding surfaces 24a of the carriage 4 is larger than the width L5 of the two recording units 3. For example, it is preferable that L1 is greater than 1.5 times L5. That is, the carriage 4 is affected by a rotational force that tries to rotate around the transport direction when accelerating or decelerating. If the distance between the sliding surfaces 24a on both sides in the movement direction is sufficiently greater than the width of the recording unit 3 in the movement direction, the effect of this rotational force is reduced and the movement of the carriage 4 is stabilized. In addition, 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 formed on the reversal position side, making it difficult for the opening and closing mechanism to interfere with the carriage 4. Note that the length L3 of the space on the reversal position side may be greater than the length L4 of the space on the start position side.

[0019] 8 to 10 show an opening / closing mechanism that controls the opening and closing of the scanner unit 2. FIG. 8 shows the opening / closing mechanism when the scanner unit 2 is in the closed position. FIG. 9 shows the opening / closing mechanism when the scanner unit 2 is in the open position. FIG. 10 shows the rail mechanism 6. In FIGS. 8 and 9, the recording unit 3, the carriage 4, and the guide unit 7 are shown in schematic diagrams with two-dot chain lines. The opening / closing mechanism has a stay 5 and a rail mechanism 6. The rail mechanism 6 is disposed on the exterior panel side of the left side surface of the stay 5. One end of the stay 5 is supported by the scanner unit 2 so as to be able to swing, and the other end has a tip protrusion 5a. The tip protrusion 5a can move along the groove of the rail mechanism 6. In FIG. 9, the stay 5 is biased counterclockwise (toward the exterior panel on the rear surface) with respect to the scanner unit 2. The rail mechanism 6 has an inclined portion 6c that approaches the discharge port 32 as it approaches the bottom surface of the main body 1, a loop portion 6d that guides the tip protrusion 5a in a loop shape, and a flapper 6a that determines the movement trajectory of the tip protrusion 5. The end 6e of the rail mechanism 6 is below the frame 17. When the scanner unit 2 is in the closed position, the tip projection 5a of the stay 5 is located at a position 5a-1 close to the end 6e of the rail mechanism 6. As the scanner unit 2 is opened, the tip projection 5a rises on the inclined portion 6c of the rail mechanism 6 and is guided by the flapper 6a to pass through the position 5a-2 and reach the corner at the position 5a-3. The flapper 6a is biased counterclockwise in FIG. 10 so that the tip projection 5a can move in one direction on the loop portion 6d. At the position 5a-3, the movement of the tip projection 5a in the Z direction and the Y direction is restricted by the corner of the rail mechanism 6. As a result, the scanner unit 2 cannot move in the opening direction. When the scanner unit 2 is moved from the position 5a-3 in the closing direction, the tip projection 5a is locked by the locking portion 6b at the position 5a-4. As a result, the stay 5 can hold the scanner unit 2 in the open position because the weight of the scanner unit 2 is applied to the stay 5 while it is locked by the locking portion 6b of the rail mechanism 6. When the scanner unit 2 is in the open position, the user can perform maintenance on the inside of the main body 1. Maintenance includes, for example, attaching and detaching the recording unit 3, and removing a sheet when a jam occurs.

[0020] Next, when the scanner unit 2 held in the open state is moved in the open direction, the tip protrusion 5a moves in the Y direction due to the counterclockwise biasing force and reaches the corner of the position 5a-5. At the position 5a-5, the tip protrusion 5a is restricted by the corner of the rail mechanism 6 and cannot move in the open direction. When the tip protrusion 5a descends from the state restricted by the corner of the position 5a-5, the tip protrusion 5a moves along the groove of the rail mechanism 6 and pushes the flapper 6a apart. The tip protrusion 5 can descend from the position 5a-5 by the weight of the scanner unit 2 or the user's operation. Furthermore, the tip protrusion 5a descends along the inclined portion 6c and reaches the position 5a-1. When the tip protrusion 5a reaches the position 5a-1, the scanner unit 2 is stabilized in a state in which it closes the lower housing 8. As a result, the scanner unit 2 and the main body unit 1 return to a normal usable state. As a user's operation, the scanner unit 2 is manually opened from the closed position until it stops, and the hand is released from the scanner unit 2. The scanner unit 2 is held in the open position by the tip protrusion 5a being locked by the locking portion 6b. To return the scanner unit 2 to the closed position, the user opens the scanner unit 2 from the open position until it stops, and then releases the scanner unit 2 or presses down on the scanner unit 2. The scanner unit 2 then descends to the closed position under its own weight. In this way, the opening and closing mechanism holds the scanner unit 2 in the open position, releases the open position, holds it in the closed position, and further controls the movement between the open position and the closed position.

[0021] FIG. 11 is a diagram showing the positional relationship between the opening / closing mechanism and the carriage 4. The reversing position where the carriage 4 is closest to the opening / closing mechanism in the width direction of the sheet is indicated by a solid line, and the starting position where the carriage 4 is farthest away is indicated by a two-dot chain line. The reversing position differs depending on the width of the sheet. Here, the maximum sheet width is shown. When viewed from the moving direction (X direction) of the carriage 4, the opening / closing mechanism overlaps at least a part of the front 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 part 4a. Also, when viewed from the transport direction (Y direction), when the carriage 4 is at the reversing position, the stay 5 and the rail mechanism 6 overlap with the support part 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 recording device can reduce the width in the width direction of the sheet. Alternatively, either the stay 5 or the rail mechanism 6 may be configured to overlap the support portion 4a.

[0022] However, if the opening / closing mechanism is located on the hinge side where it does not overlap with the recording unit 3 in the transport direction, the force applied to the parts increases due to the leverage ratio when the scanner unit 2 is held in the open position. In this case, it becomes necessary to strengthen the stay 5, the rail mechanism 6, and the scanner unit 2. This requires space for reinforcement, and the cost increases to increase the strength. On the other hand, if the opening / closing mechanism is located forward so as not to overlap with the recording unit 3 in the transport direction, the stroke of the stay 5 is insufficient, and the opening angle of the scanner unit 2 becomes small. In this case, it becomes difficult to perform tasks such as attaching and detaching the recording unit 3 and removing a sheet when a jam occurs.

[0023] FIG. 12 is a diagram showing the positional relationship between the carriage 4 and the drive mechanism of the conveying roller 10. The carriage 4 is shown in a solid line when it is in the reverse position, and in a two-dot chain line when it is in the start position. The stay 5 and the rail mechanism 6 are each shown in a two-dot chain line. A guide unit 7, a conveying roller 10, and a discharge roller 11 are arranged downstream in the conveying direction. The drive mechanism is a mechanism that transmits a driving force from a conveying motor (not shown) to the conveying roller 10 and the discharge roller 11. The drive mechanism includes a conveying roller gear 12, a discharge roller gear 14, and an intermediate gear. The conveying motor can rotate the conveying roller 10 and the discharge roller 11 in the same direction to convey the sheet downstream in the conveying direction. The conveying roller 10 and the discharge roller 11 are arranged in parallel with the guide unit 7. The conveying roller gear 12 is arranged between the exterior panel on the left side surface and the conveying roller 10, and transmits a driving force to the conveying roller 10. A code wheel 13 for measuring the amount of rotation of the conveying roller 10 is arranged coaxially with the conveying roller 10. A sensor (not shown) reads the code wheel 13 to measure the amount of rotation of the conveying roller 10. By measuring the amount of rotation, the control unit can control the amount of conveyance and the conveyance speed of the sheet. The code wheel 13 may be arranged so as to overlap the area Xa when viewed from the conveying direction, but since the diameter of the code wheel 13 is large, it may be arranged so as not to overlap the area Xa. Similarly, the discharge roller gear 14 is arranged between the exterior panel on the left side and the discharge roller 11, and transmits a driving force to the discharge roller 11. The conveying roller gear 12 and the discharge roller gear 14 are arranged at a position overlapping the area Xa when viewed from the conveying direction. Since a part of the drive mechanism is arranged at a position overlapping the area Xa in this way, the width of the recording device can be reduced. Furthermore, the power supply unit 9 is arranged between the frame 17 and the exterior panel on the rear side on the opening / closing mechanism side of the recording device. A part of the power supply unit 9 overlaps the area Xa when viewed from the conveying direction.

[0024] FIG. 13 is a diagram showing the arrangement of the cable 26 connecting the operation panel 31 and the control board 28. The control board 28 is arranged along the frame 17 on the exterior panel side at the rear of the frame 17. A connector 34 may be arranged on the control board 28. The connector 34 enables the control board 28 to communicate with external devices. The cable 26 is a flexible flat cable (FFC) that connects the control board 28 and the operation unit 15. The cable 26 is wired between the exterior panel on the left side and the rail mechanism 6. On the back side of the loop portion 6d of the rail mechanism 6, the rail mechanism 6 has a holding portion that can hold the cable 26. A ferrite core 27 that reduces noise from the cable 26 is arranged on the cable 26. An extension from the rail mechanism 6 holds the ferrite core 27. As described above, the opening / closing mechanism is disposed at a position overlapping with the recording unit 3 when viewed from the moving direction of the carriage 4, and is disposed at a position overlapping with the support portion 4a when viewed from the conveying direction of the sheet. This configuration makes it possible to reduce the width of the recording device and realize a sufficient opening angle of the scanner portion 2.

[0025] [Second embodiment] 14 shows the opening / closing mechanism of the scanner section 2 in the second embodiment. The recording unit 3, carriage 4, and guide section 7 are indicated by two-dot chain lines. In the second embodiment, the stay 5 and rail mechanism 6 of the opening / closing mechanism are replaced with a different system. The arrangement of each is the same as in the first embodiment. That is, when viewed from the movement direction of the carriage 4, the opening / closing mechanism is disposed at a position overlapping with the front of the recording unit 3, and when viewed from the conveyance direction of the sheet, it is disposed at a position overlapping with the support section 4a at the inverted position.

[0026] In the opening / closing mechanism, a stay 51 having a fan-shaped gear is provided on the scanner unit 2 and is connected to a gear mechanism 61 provided on the main body unit 1. The gear mechanism 61 has a first-stage connecting gear, a final-stage brake means, and an intermediate gear. The first-stage connecting gear moves slightly in the swinging direction of the stay 51, thereby transmitting drive to the final-stage brake means when the scanner unit 2 is moving in the closing direction. On the other hand, when the scanner unit 2 is moving in the opening direction, the first-stage connecting gear moves slightly upward, cutting off the drive transmission. With this configuration, it is possible to brake only the rotation of the scanner unit 2 in the closing direction. In addition, the scanner unit 2 is a free-stop type that holds its posture at any position during opening or closing.

[0027] The brake means at the final stage may be replaced with a damper means and used in combination with the opening and closing mechanism of the scanner unit 2 of the first embodiment. In this case, the rotation of the scanner unit 2 in the closing direction can be damped, and the operation speed can be slowed down.

[0028] As described above, the width of the recording device can be reduced and a sufficient opening angle of the scanner unit 2 can be achieved. [Explanation of symbols]
