Description

Technical Field

[0001] The present invention relates to a recording apparatus, and more particularly to a recording apparatus provided with a lock mechanism that can enter the scanning path of a recording unit.

Background Art

[0002] As a recording apparatus, a configuration including a liquid discharge head that discharges a liquid toward a recording medium and a carriage that supports the liquid discharge head and is configured to be movable in a scanning direction is known. In such a configuration, for example, in order to maintain the state in which the liquid discharge head is capped by a cap mechanism or the like during transportation, there is a recording apparatus provided with a lock mechanism that can enter the scanning path of the recording unit.

[0003] When transporting the recording apparatus, if the lock mechanism unintentionally retreats from the scanning path of the recording unit due to an impact such as a fall, the recording unit becomes movable in the scanning direction, and the capping state of the liquid discharge head may not be maintained. In Patent Document 1, in order to prevent the release of the restricted state of the recording unit by an external force, a configuration including a slide member that blocks the movement of the carriage and a drive pin that moves the slide member into and out of the scanning path of the carriage is disclosed. In the above configuration, a portion for locking the drive pin is provided in a groove hole that engages with the drive pin, and the locked state of the carriage is maintained even when the slide member receives an external force.

[0010] <First Example> (Image forming apparatus) FIG. 1 is a perspective view showing the internal configuration of an image forming apparatus M which is a recording apparatus according to a first embodiment of the present invention. In the following description, as shown in FIG. 1, the direction from the left side surface to the right side surface of the image forming apparatus M is defined as the x direction, the direction from the back surface to the front surface of the image forming apparatus M is defined as the y direction, and the vertically upward direction is defined as the z direction. In this embodiment, the width direction of the recording medium conveyed inside the image forming apparatus M is substantially parallel to the x direction, and the conveyance direction of the recording medium is substantially parallel to the y direction.

[0011] The image forming apparatus M is a multifunction device including a printing unit and a scanner unit (not shown) disposed above the printing unit, and can execute various processes related to an image recording operation and a reading operation individually or in conjunction with the printing unit and the scanner unit. The scanner unit includes an ADF (auto document feeder) and an FBS (flatbed scanner), and can read a document automatically fed by the ADF and a document placed on the document table of the FBS (scanned) by the user. Although this embodiment is a multifunction device having both a printing unit and a scanner unit, the present invention is applicable to other image forming apparatuses such as a printer not provided with a scanner unit.

[0012] The printing unit of the image forming apparatus M includes a paper feeding unit 1 on which a recording medium is loaded, a conveyance unit 3 that conveys the recording medium fed from the paper feeding unit 1, and a recording unit 4 as a recording means for recording an image on the recording medium conveyed from the conveyance unit 3. Further, the printing unit includes a paper discharging unit 8 where the recording medium on which an image is recorded is discharged and loaded, a maintenance unit 5 that performs maintenance on the recording head 42 of the recording unit 4, and a driving unit 6 that transmits the drive of the conveyance motor 31 of the conveyance unit 3 to the paper feeding unit 1 and the maintenance unit 5.

[0013] The paper feeding unit 1 includes a paper feeding roller 11, and conveys the loaded recording medium to the conveyance unit 3 by the paper feeding roller 11. The conveyance unit 3 includes a conveyance motor 31 that can rotate forward and backward as a drive source, and a conveyance roller 32 driven by the conveyance motor 31, and conveys the recording medium to an area where recording is performed by the recording unit 4 by the conveyance roller 32. [[ID=​The recording unit 4 is a recording means comprising a carriage 41, a recording head 42 held by the carriage 41, a carriage motor 43 that drives the carriage 41, and a chassis 44 that holds the carriage 41 and guides its movement. The recording unit 4 performs a recording operation by ejecting a liquid such as ink from the recording head 42 onto a recording medium transported from a transport unit 3 located upstream of the recording unit 4 in the transport direction of the recording medium. In this embodiment, the liquid ejection direction of the recording head 42 as a liquid ejection head is substantially parallel to the vertical direction (z direction). The carriage 41 is capable of reciprocating movement along a scanning path that extends from one end to the other in the x direction within the image forming apparatus M along the chassis 44. During the recording operation onto the recording medium, the recording head 42 moves integrally with the carriage 41 in the x direction while ejecting liquid toward the recording medium.

[0015] The paper output section 8 includes a stacking section 8a for stacking recording media and an extension tray 8b that can be pulled out relative to the image forming apparatus M to support recording media when the size of the recording media is large in the y direction.

[0016] The maintenance unit 5 includes a mechanism for bringing a suction cap into contact with the recording head 42, and a suction mechanism for drawing ink from the ink outlet of the recording head 42 using a tube pump. The image forming apparatus M is also provided with a locking mechanism 60 for locking the carriage 41 in the position where the suction cap is in contact with the recording head 42. The locking mechanism 60 stably maintains the capped state of the recording head 42 and restricts the movement of the carriage 41 during logistics and transport. Details of the configuration for holding the position of the carriage 41 with the locking mechanism 60 will be described later.

[0017] All of the aforementioned units that constitute the printed circuit board are fastened to the main body base 7. Furthermore, the circuit board (not shown) that controls the operation of these units is positioned and held by the main body base 7 and the chassis 44.

[0018] (Printing operation) Figure 2 is a block diagram of the image forming apparatus M of this embodiment. The image forming apparatus M comprises an MPU 901, a ROM 902, and a RAM 903. The MPU 901 is an MPU that controls the operation of each part and the processing of data. The ROM 902 is a ROM that stores programs and data executed by the MPU 901 and includes an image processing unit 9021. The RAM 903 is a RAM that temporarily stores processing data executed by the MPU 901 and data received from the host computer 906.

[0019] The image forming apparatus M further includes a recording head driver 942 that controls the recording head 42, a carriage motor driver 943 that controls the carriage motor 43, and a transport motor driver 931 that controls the transport motor 31. The MPU 901 controls the recording head driver 942, the carriage motor driver 943, the transport motor driver 931, and the operation display unit 904. The carriage 41 is driven by the carriage motor 43, and the paper feed roller 11, transport roller 32, and discharge roller are driven by the transport motor 31.

[0020] The host computer 906, when commanded by the user to perform a recording operation, processes recording information such as the recorded image and image quality, and communicates with the image forming apparatus as a printer driver. It has a 9061. The MPU 901 exchanges recorded images and other data with the host computer 906 via the I / F unit 905.

[0021] (Drive unit) Next, the configuration of the drive unit 6 of the first embodiment will be described with reference to Figures 3, 4, 5(a), and 5(b). Figure 3 is a perspective view of the drive unit 6 driven by the transport motor 31, which is the drive source. Figure 4 is an exploded perspective view of the drive unit 6. Figure 5(a) is a cross-sectional view of the drive unit 6, and Figure 5(b) is a cross-sectional view showing the fitting configuration of the drive unit 6.

[0022] The drive unit 6 includes an input gear 61 and a locking mechanism 60 driven by the input gear 61. The input gear 61 is connected to the transport motor 31 via a drive train (not shown), a transport roller 32, and an idler gear 69, and rotates when the driving force of the transport motor 31 is transmitted to it. The locking mechanism 60 includes a drive member 62, a lever member 63, a swing restricting member 66, and a base member 67.

[0023] The drive member 62 is a rotating member that receives driving force from the input gear 61 and rotates concentrically with the input gear 61 around the rotation axis 61c. The drive member 62 has a link portion 62a that extends cylindrically parallel to the rotation axis 61c at a different position from the rotation axis 61c. When the drive member 62 rotates, the link portion 62a moves in a circular motion around the rotation axis 61c. In other words, the input gear 61 is a drive transmission member that transmits the driving force of the transport motor 31 to the drive member 62 and drives the drive member 62 to rotate concentrically.

[0024] The lever member 63 is a pivoting member supported by the base member 67 so as to be able to pivot about a pivot axis 63c that extends parallel to the rotation axis 61c at a different position from the rotation axis 61c. The lever member 63 has a cam surface 63a that is pressed by a link portion 62a and an engaging portion 63b that restricts the scanning of the carriage 41. As the drive member 62 rotates, the link portion 62a slides on the cam surface 63a and presses against it, causing the lever member 63 to pivot about the pivot axis 63c while being restricted by the link portion 62a. In this embodiment, by pivoting the lever member 63 and changing its posture, the engaging portion 63b enters or retracts from the scanning path of the carriage 41.

[0025] The input gear 61 has a cylindrical shaft portion extending around the rotation axis 61c, and the outer and inner surfaces of this shaft portion function as a fitting shaft 61d and a fitting hole 61h for fitting with each component of the drive unit 6. The cross-sectional shape of each fitting portion of the input gear 61 is circular around the rotation axis 61c of the input gear 61. The drive member 62 also has a cylindrical shaft portion extending around the rotation axis 61c, and the outer surface of this shaft portion functions as a fitting shaft 62h that fits with the fitting hole 61h of the input gear 61.

[0026] The base member 67 is a support member that supports the components of the drive unit 6 and is attached to the main body base 7 as described in Figure 1. The base member 67 also has a shaft support portion 67d that engages with the fitting shaft 61d of the input gear 61. The input gear 61 is rotatably supported on the base member 67 by the fitting shaft 61d being inserted through the shaft support portion 67d. The drive member 62 is a rotating member that is rotatably supported on the input gear 61 by having its fitting shaft 62h inserted through a fitting hole 61h, which is the inner circumferential surface of the cylindrical portion of the input gear 61.

[0027] Furthermore, the locking mechanism 60 is provided with a friction means 64 that biases the fitting hole 61h in a direction that presses it against the fitting shaft 62h. The friction means 64 causes the fitting shaft 62h to come into contact with the fitting hole 61h, thereby transmitting driving force from the input gear 61 and causing the drive member 62 to rotate. In this embodiment, the friction means 64 is a spring member that biases the input gear 61 and the drive member 62. Note that the friction means 64 is not limited to biasing members such as springs; for example, a viscous substance such as grease may also be used. This could be adopted. By applying a viscous substance such as grease between the mating hole 61h and the mating shaft 62h, the frictional force increases, and the drive member 62 rotates in conjunction with the rotation of the input gear 61.

[0028] (Carriage locking method) Next, with reference to Figures 6(a) to 6(d), a locking method for securing the carriage 41 on which the recording head 42 is mounted in the capping position using the locking mechanism 60 of this embodiment will be described.

[0029] Figure 6(a) is a perspective view showing the positional relationship between the carriage 41 and the locking mechanism 60. Figure 6(b) is a top view showing the positional relationship between the carriage 41 and the locking mechanism 60. Figure 6(c) is a schematic top view showing an enlarged view of the engagement point between the carriage 41 and the locking mechanism 60. Figure 6(d) is a schematic top view showing the positional relationship between the locking mechanism 60 and the opening 7a of the main body base 7.

[0030] The carriage 41 has a contact portion 41a that faces the chassis end portion 44a when the locking mechanism 60 is in a position that restricts the scanning of the carriage 41, and an engaged portion 41b that faces the locking mechanism 60. When recording is performed on the recording medium, the carriage 41 scans in the scanning direction 411 indicated by the arrows in Figures 6(a) and (b). On the other hand, to prevent the carriage 41 from moving unintentionally, such as during logistics, the carriage 41 is locked in a capping position by the locking mechanism 60 to restrict its movement.

[0031] When the scanning of the carriage 41 is restricted by the locking mechanism 60, the engaging portion 63b, which is the locking portion at the tip of the lever member 63, is positioned on the scanning path of the carriage 41, as shown in Figures 6(a) and (b). In this way, the engaging portion 63b of the lever member 63 faces the engaged portion 41b of the carriage 41, and the position of the lever member 63 when the engaging portion 63b restricts the movement of the carriage 41 in the scanning direction 411 is called the operating position. Alternatively, the engaging portion 63b can be retracted from the scanning path of the carriage 41 and will not restrict the scanning of the carriage 41.

[0032] As described above, the transport roller 32, driven by the transport motor 31, is transmitted to the drive member 62 via the idler gear 69 and input gear 61. When the transport roller 32 is driven in the forward direction (the direction in which the recording medium is transported toward the discharge roller), the lever member 63 swings around the pivot axis 63c and moves to a non-operating position (retracted side) where the engaging portion 63b does not obstruct the scanning path of the carriage 41. At this time, the lever member 63 is in a non-operating state in which it is disengaged from the carriage 41, and the carriage 41 is not restricted from reciprocating movement in the scanning direction 411.

[0033] On the other hand, when the transport roller 32 is driven in the reverse direction (opposite to the forward direction), the lever member 63 swings around the pivot axis 63c. The lever member 63 then moves to an operating position that locks the carriage 41, and the engaging portion 63b of the lever member 63 blocks the scanning path of the carriage 41. At this time, the carriage 41 is blocked on one side of the scanning direction 411 by the chassis end 44a and on the other side by the engaging portion 63b, and its movement from that position is restricted. That is, when the carriage 41 is located at one end of the chassis 44 in the scanning direction 411, the carriage 41 is sandwiched between the chassis end 44a of the chassis 44 and the engaging portion 63b of the lever member 63.

[0034] With the above configuration, even if force is applied to the carriage 41, the contact portion 41a provided at one end of the carriage 41 in the scanning direction 411 contacts the chassis end portion 44a of the chassis 44, thereby restricting the movement of the carriage 41. Similarly, the engaged portion 41b provided at the other end of the carriage 41 opposite to the end where the contact portion 41a is provided contacts the engaged portion 63b of the lever member 63, thereby restricting the movement of the carriage 41. In other words, at the capping position, the carriage 41 is restricted from moving in the scanning direction 411, and its position is fixed.

[0035] Furthermore, the engaged portion 41b of the carriage 41 has a first inclined surface 41e, and the engaged portion 63b of the lever member 63 has a second inclined surface 63e. As shown in Figure 6(c), the first inclined surface 41e and the second inclined surface 63e are inclined with respect to a plane perpendicular to the scanning direction 411 when viewed from the vertical direction (z direction). When the locking mechanism 60 is in the operating position, and the carriage 41 moves towards the lever member 63 along the scanning direction 411, the first inclined surface 41e presses against the second inclined surface 63e. The first inclined surface 41e and the second inclined surface 63e are, respectively, inclined with respect to a plane perpendicular to the scanning direction 411 that the carriage 41 scans. The first inclined surface 41e and the second inclined surface 63e are inclined such that the pressing force applied by the carriage 41 to the lever member 63 acts in a direction that pulls the lever member 63 toward the carriage 41 in the y-direction, which is perpendicular to the scanning direction 411. In other words, the more the carriage 41 is pushed toward the lever member 63 in the scanning direction 411, the greater the force that pulls the carriage 41 and the lever member 63 toward each other, making it difficult to disengage the carriage 41 and the lever member 63.

[0036] Furthermore, when the locking mechanism 60 is in the operating position, the engaging portion 63b is inserted through the opening 7a formed in the main body base 7. As shown in Figure 6(d), the inner circumferential surface 7e of the opening 7a faces the second inclined surface 63e of the engaging portion 63b, and the inner circumferential surface 7f of the opening 7a faces the end portion 63f of the engaging portion 63b opposite to the second inclined surface 63e. With this configuration, even if the engaging portion 63b is deformed by force, the position of the engaging portion 63b is unlikely to change because the second inclined surface 63e or the end portion 63f will come into contact with the inner circumferential surface 7f. Consequently, the carriage 41 is securely locked in the capping position.

[0037] The locking method described above allows the carriage 41 to be restricted to a predetermined position. Consequently, it is possible to prevent the carriage 41 from moving from its capping position due to unintended impacts during transport, etc., thereby preventing damage to the carriage 41 and the suction cap from coming off the recording head 42.

[0038] (Operation of the locking mechanism) Next, the posture and operation of the locking mechanism 60 will be explained with reference to Figures 7(a) to 7(d) and 8(a) to 8(d). Figures 7(a) to 7(d) are side views showing the operation of the drive member 62, and Figures 8(a) to 8(d) are side views showing the operation of the lever member 63 which is linked to the drive member 62. In Figures 7(a) and 8(a), the posture of the drive member 62 is the same, and the position of the link portion 62a is the same. Similarly, in Figures 7(b) and 8(b), 7(c) and 8(c), and 7(d) and 8(d), the posture of the drive member 62 is the same, and the position of the link portion 62a is the same.

[0039] The drive member 62 is rotatable around the rotation axis 61c in a first rotation direction 621 and a second rotation direction 622. When the transport roller 32 rotates in the forward direction for feeding paper, the drive member 62 rotates in the second rotation direction 622, and when the transport roller 32 rotates in the opposite direction to the forward direction, the drive member 62 rotates in the first rotation direction 621. During printing, as shown in Figure 8(a), the drive member 62 rotates in the second rotation direction 622, and the lever member 63 swings in a direction that moves the engaging portion 63b away from the scanning path of the carriage 41, so that the scanning of the carriage 41 is not restricted.

[0040] The cam surface 63a of the lever member 63 has a flat portion 63a1 and a curved portion 63a2. The link portion 62a slides and presses on the cam surface formed by the flat portion 63a1 and the curved portion 63a2, causing the lever member 63 to swing. The operation in which the drive member 62 and the lever member 63 move in conjunction will be described below.

[0041] First, we will explain the positional relationships and orientations of each component that change with the rotation of the drive member 62, by considering different cases. As described above, the drive member 62 is rotatable in a first rotational direction 621 and a second rotational direction 622 about the rotation axis 61c. The lever member 63 is also oscillating in a first oscillation direction 631 and a second oscillation direction 632 about the oscillation axis 63c when the drive member 62 rotates and the cam surface 63a is pressed against the link portion 62a. In Figures 7(a) to 8(d) and 8(a) to 8(d), the trajectory 623 of the link portion 62a that moves with the rotation of the drive member 62 is shown by a solid line.

[0042] Figures 7(a) and 8(a) show the positions of the drive member 62 and lever member 63 when the image forming apparatus M is in printing operation and the locking mechanism 60 is in the non-operating position. As shown in Figure 8(a), the first contact portion 63d of the lever member 63 is in contact with the first contacted portion 66d of the swing restricting member 66, and the swing of the lever member 63 in the first swing direction 631 is restricted. Also, as shown in Figure 7(a), the link portion 62a of the drive member 62 is in contact with a part of the lever member 63 (cam surface 63a). Since the swing of the lever member 63 in the second swing direction 632 is restricted, the rotation of the drive member 62 in the second rotation direction 622 is restricted. In other words, during printing operation, the position of the drive member 62 is determined by the lever member 63, and the position of the lever member 63 is determined by the swing restricting member 66.

[0043] Figures 7(b) and 8(b) show the positions of the drive member 62 and lever member 63 when the drive member 62 rotates in the first rotational direction 621 from the state shown in Figures 7(a) and 8(a), and the locking mechanism 60 moves from the non-operating position to the operating position. As shown in Figure 7(b), the drive member 62 is not restricted from rotating in the first rotational direction 621 and the second rotational direction 622.

[0044] As shown in Figure 8(b), the link portion 62a is located at the boundary between the flat portion 63a1 and the curved portion 63a2. When the locking mechanism 60 is in the non-operating position, the rotation center of the drive member 62 and the arc center of the curved portion 63a2 of the cam surface 63a coincide. Therefore, even if the drive member 62 changes from the state shown in Figure 8(a) to the state shown in Figure 8(b), the link portion 62a does not press against the cam surface 63a, and the posture of the lever member 63 does not change. Furthermore, as shown in Figure 8(b), the first contact portion 63d of the lever member 63 is in contact with the first contacted portion 66d of the swing restricting member 66, and the swing of the lever member 63 in the second swing direction 632 is restricted.

[0045] Figures 7(c) and 8(c) show the positions of the drive member 62 and lever member 63 when the drive member 62 rotates in the first rotational direction 621 from the state shown in Figures 7(b) and 8(b), and the engaging portion 63b of the lever member 63 is positioned on the scanning path of the carriage 41. As shown in Figure 7(c), the drive member 62 is not restricted from rotating in the first rotational direction 621 and the second rotational direction 622.

[0046] In this embodiment, when the lever member 63 is in the state shown in Figure 8(c), the engagement between the engaging portion 63b of the lever member 63 and the engaged portion 41b of the carriage 41 is maximized, and the lever member 63 and carriage 41 are configured to maximize the contact area. At this time, the link portion 62a is at the top dead center.

[0047] Figures 7(d) and 8(d) show the positions of the drive member 62 and lever member 63 when the drive member 62 is rotated in the first rotational direction 621 from the state shown in Figures 7(c) and 8(c). As shown in Figure 7(d), the second contact portion 62b of the drive member 62 is in contact with the second contacted portion 67a of the base member 67, and the rotation of the drive member 62 in the first rotational direction 621 is restricted. In other words, the base member 67 functions as a restricting member that restricts the rotation of the drive member 62. In the following description, the state in which the drive member 62 and lever member 63 are in the state shown in Figure 8(d) and the positions of the drive member 62 and lever member 63 are fixed will be referred to as the locked state.

[0048] In this embodiment, the second contact portion 67a is provided on the base member 67, but a different member may be provided to restrict the rotation of the drive member 62. In this way, once the positions of the drive member 62 and the lever member 63 are determined and the locking mechanism 60 is locked, even if the lever member 63 is subjected to an external force, it is possible to prevent the lever member 63 from unintentionally moving away from the scanning path of the carriage 41. Details of the locked state will be described later.

[0049] Next, the movement of each component when the drive member 62 rotates will be described. In the following description, the range of the trajectory 623 traced by the link portion 62a from the state shown in Figure 7(c) to the state shown in Figure 7(d) will be referred to as the first region 623a. Similarly, the range of the trajectory 623 traced by the link portion 62a from the state shown in Figure 7(b) to the state shown in Figure 7(c) will be referred to as the second region 623b, and the range of the trajectory 623 traced by the link portion 62a from the state shown in Figure 7(a) to the state shown in Figure 7(b) will be referred to as the third region 623c. In other words, in the second rotation direction 622 of the drive member 62, the second region 623b is located downstream of the first region 623a, and the third region 623c is located downstream of the second region 623b. The operation of the lever member 63 when the link portion 62a moves within each region will be described below.

[0050] First, the movement of each component of the locking mechanism 60 from the state shown in Figure 8(a) to the state shown in Figure 8(b) will be explained. At this time, the link portion 62a moves within the third region 623c. As shown in Figures 8(a) and (b), when the link portion 62a is within the third region 623c, the lever member 63 is retracted from the scanning path of the carriage 41, and the engaging portion 63b is in a position where it does not engage with the engaged portion 41b. Also, as described above, even if the drive member 62 rotates in the first rotational direction 621 from the state shown in Figure 8(a) to the state shown in Figure 8(b), the cam surface 63a of the lever member 63 is not pressed by the link portion 62a. Therefore, even if the drive member 62 rotates in the first rotational direction 621, the lever member 63 does not swing. In other words, when the link portion 62a moves within the third region 623c, the link portion 62a slides on the cam surface 63a, but the cam surface 63a is not pressed against by the link portion 62a. That is, the third region 623c of the trajectory 623 of the link portion 62a is a dead zone region where the lever member 63 does not operate, and is a region for the delay period until the lever member 63 enters the scanning path of the carriage 41.

[0051] Next, the movement of each component of the locking mechanism 60 from the state shown in Figure 8(b) to the state shown in Figure 8(c) will be described. At this time, the link portion 62a moves within the second region 623b. As shown in Figures 8(b) and (c), when the drive member 62 rotates in the first rotational direction 621 while the link portion 62a is within the second region 623b, the flat portion 63a1 of the cam surface 63a is pressed against the link portion 62a, causing the lever member 63 to swing in the first oscillation direction 631. That is, the movement of the link portion 62a within the second region 623b causes the engaging portion 63b of the lever member 63 to enter the scanning path of the carriage 41.

[0052] Next, the movement of each component of the locking mechanism 60 from the state shown in Figure 8(c) to the state shown in Figure 8(d) will be described. At this time, the link portion 62a moves within the first region 623a. When the drive member 62 rotates in the first rotational direction 621 while the link portion 62a is in the first region 623a, the flat portion 63a1 of the cam surface 63a is pressed against the link portion 62a. As a result, the lever member 63 swings in the second swinging direction 632, albeit by a small amount of movement.

[0053] Furthermore, when the drive member 62 rotates in the second rotational direction 622, and the above-described movements are performed in reverse order, the locking mechanism 60 transitions from the state shown in Figure 8(d) to the state shown in Figure 8(c) and Figure 8(b), and then to the state shown in Figure 8(a). That is, the transport motor 31 rotates the drive member 62 in the first rotational direction 621 and the second rotational direction 622, causing the lever member 63 to enter or retract from the scanning path of the carriage 41.

[0054] (Locked state of the oscillating member) Next, with reference to Figures 9(a) and (b), the locked state of the locking mechanism 60, where the positions of the drive member 62 and the lever member 63 are determined, will be described in detail. For example, if the lever member 63 moves to a non-operating position that does not restrict the scanning of the carriage 41 due to an impact during the logistics process of the image forming apparatus M, the carriage 41 may move unintentionally, potentially leading to damage to the carriage 41 or malfunctions in the image forming operation. Therefore, in this embodiment, the locking mechanism 60 is locked to prevent the lever member 63, which is in the operating position, from unintentionally moving to the non-operating position.

[0055] Figure 9(a) shows the situation when an external force Fa acts on the lever member 63, causing it to swing in the second swing direction 632, while the link portion 62a of the drive member 62 is in the first region 623a. The position of the drive member 62 at this time is defined as the first angle. When the lever member 63, which is in the non-operating position, attempts to swing in the second swing direction 632 due to the external force Fa, a force Fb1 is applied from the cam surface 63a to the link portion 62a. This force Fb1 acts on the drive member 62, which is in the first angle, in a direction that causes it to rotate in the first rotation direction 621.

[0056] At the first angle, the second contact portion 62b is in contact with the second contacted portion 67a of the base member 67, so the drive member 62, which receives the force Fb1, is restricted from rotating in the first rotational direction 621. Since the drive member 62 does not rotate, the lever member 63 is also restricted from swinging in the second swinging direction 632 by the cam surface 63a. In other words, at this time, the force Fc applied from the second contact portion 62b to the second contacted portion 67a balances the reaction force that the drive member 62 receives from the second contacted portion 67a, and the posture of the drive member 62 and the lever member 63 does not change. With this configuration, even if an external force is applied to the lever member 63 in the locked state, the swing of the lever member 63 in the second swinging direction 632 is restricted, and the locked state of the locking mechanism 60 is maintained. In other words, when the link portion 62a is located in the first region 623a and the drive member 62 is at the first angle, the second contact portion 67a restricts the rotation of the drive member 62 in the first rotational direction 621, and the position of the lever member 63 is also maintained.

[0057] Figure 9(b) shows the situation when an external force Fa acts on the lever member 63, causing it to swing in the second swing direction 632, while the link portion 62a of the drive member 62 is located in the second region 623b. When the drive member 62, which is at the first angle, rotates in the second rotation direction 622, the link portion 62a moves from the first region 623a to the second region 623b. The position of the drive member 62 at this time is defined as the second angle. When the drive member 62 is at the second angle, the link portion 62a is located in the second drive region 632b.

[0058] As described above, the external force Fa acts in a direction that causes the lever member 63 to swing in the second swinging direction 632. At this time, a force Fb2 is applied from the cam surface 63a to the link portion 62a. The force Fb2 acts on the drive member 62, which is at the second angle, in a direction that causes the drive member 62 to rotate in the second rotational direction 622. As a result, the drive member 62 rotates in the second rotational direction 622 without restriction of rotation, and the lever member 63 swings in the second swinging direction 632.

[0059] Furthermore, according to the configuration of this embodiment, contrary to Figure 9(a), even when a force is applied that rotates the lever member 63 in the first swinging direction 631, the lever member 63 maintains a position in which the engaging portion 63b can contact the engaged portion 41b. This is because the drive member 62 and the lever member 63 transition from the state in Figure 8(d) to the state in Figure 8(c) and stop moving. Therefore, even when an external force is applied in that direction, the amount of movement of the lever member 63 is small, and the lever member 63 is held in a constant position.

[0060] As described above, according to this embodiment, when the locking mechanism 60 is in the locked state, even if an external force is applied to the lever member 63, it is possible to prevent the lever member 63 from moving from its operating position. Since the rotation of the drive member 62 is restricted by the base member 67, the lever member 63 hardly moves and is held in a fixed position. Consequently, the carriage 41 can be reliably prevented from moving from the capping position. Furthermore, since the lever member 63 hardly moves in the locked state, there is no need to design the engaged portion 41b of the carriage 41 considering the amount of movement of the lever member 63, and the size of the engaged portion 41b can be minimized.

[0061] (Regulatory member) Next, the oscillation restricting member 66 will be described with reference to Figures 8(a) to 8(d). The oscillation restricting member 66 is a member that can be attached to and detached from the base member 67. When the oscillation restricting member 66 is attached to the base member 67, it is positioned on the oscillation path of the lever member 63 and can restrict the oscillation of the lever member 63.

[0062] In the following description, the state of the lever member 63 when the engaging portion 63b of the lever member 63 is not on the scanning path of the carriage 41 and the engaging portion 63b is inserted inside the opening 7a is referred to as the first state. As shown in Figures 8(a) and (b), when the lever member 63 is in the first state, the locking mechanism 60 is in the non-operating position. The state of the lever member 63 when the engaging portion 63b of the lever member 63 penetrates inside the opening 7a and the engaging portion 63b is on the scanning path of the carriage 41 is referred to as the second state. As shown in Figures 8(c) and (d), when the lever member 63 is in the second state, the locking mechanism 60 is in the operating position. That is, the lever member 63 can swing between the second state and the first state by the rotation of the drive member 62. As described above, the lever member 63 in the first state swings in the first swinging direction 631 by the rotation of the drive member 62 in the first rotational direction 621 and transitions to the second state. Conversely, the lever member 63 in the second state swings in the second swinging direction 632 due to the rotation of the drive member 62 in the second rotational direction 622, and transitions to the first state.

[0063] In the first state, the lever member 63's first contact portion 63d contacts the first contacted portion 66d of the swing restricting member 66, thereby restricting its swing in the second swing direction 632. That is, when the swing restricting member 66 is attached to the base member 67, at least a portion of the engaging portion 63b of the lever member 63 is located above the lower surface of the opening 7a and passes through the interior of the opening 7a. Therefore, as shown in Figure 6(d), the engaging portion 63b is always restricted from moving the carriage 41 in the scanning direction 411 (x direction) by the inner circumferential surfaces 7e and 7f of the opening 7a, so that the positional accuracy of the engaging portion 63b relative to the carriage 41 is maintained with high precision. Therefore, when the locking mechanism 60 is in the locked state, the carriage 41 is reliably held at a predetermined capping position.

[0064] (Installation method for the drive unit) Next, a method for attaching the drive unit 6 to the main base 7 will be described with reference to Figures 10(a), (b) and 11(a), (b). Figure 10(a) is a top view showing the inside of the image forming apparatus M with the paper feeding unit 1 removed from the main base 7. Figure 10(b) is a perspective view showing the paper feeding unit 1 being attached to and detached from the main base 7.

[0065] The paper feeding unit 1 can be attached to and detached from the main body base 7 by moving it vertically (z-direction) relative to the main body base 7, and is fixed to the main body base 7 with a screw member or the like. The oscillation restricting member 66 can be attached to and detached from the image forming apparatus M (base member 67) when the paper feeding unit 1 is detached from the main body base 7. In other words, when attaching or detaching the oscillation restricting member 66, it is not necessary to remove the transport unit 3, chassis 44, or maintenance unit 5 from the main body base 7.

[0066] Figure 11(a) is a side view showing the state of the drive member 62 and lever member 63 when the swing restricting member 66 is removed from the base member 67. Figure 11(b) is a perspective view showing the drive unit 6 being attached to and detached from the main body base 7.

[0067] When the swing restricting member 66 is removed from the base member 67, the contact between the first contact portion 63d and the first contacted portion 66d is released, and the lever member 63 becomes capable of swinging from the first state to the second swing direction 632. Figure 11(a) shows the state in which the lever member 63 has swung from the first state to the second swing direction 632 and transitioned to the third state. In the third state, the engaging portion 63b of the lever member 63 comes out from inside the opening 7a of the main body base 7 and moves to a position lower than the lower surface 7b of the opening 7a. When the lever member 63 moves to the third state, the drive unit 6 becomes capable of moving in the direction of the arrow 601 shown in Figure 11(b), and the drive unit 6 can be removed from the main body base 7.

[0068] Conversely, when attaching the drive unit 6 to the main body base 7, the swing restricting member 66 is removed, and with the lever member 63 in the third state, the drive unit 6 is moved in the direction of arrow 601. After the drive unit 6 is positioned relative to the main body base 7, the swing restricting member 66 is attached to the base member 67, causing the lever member 63 to transition to the first state, and the engaging portion 63b of the lever member 63 to be positioned inside the opening 7a.

[0069] As described above, according to this embodiment, the swing restricting member 66 can be easily attached and detached, and the workability of attaching and detaching the drive unit 6 to the main base 7 is good. Furthermore, when the drive unit 6 is attached to the main base 7, the swing restricting member 66 prevents the lever member 63 from moving to the third state, and it swings only between the first and second states, thus guaranteeing the positional accuracy of the lever member 63 relative to the main base 7.

[0070] <Second Example> Next, a second embodiment of the present invention will be described with reference to Figure 12. In the first embodiment, the movement of the carriage 41 of the recording unit 4 in the scanning direction was restricted by the lever member 63 of the locking mechanism 60. On the other hand, in the second embodiment, the paper-to-paper distance between the recording head 42 and the recording medium is adjusted using the lever member 63 of the locking mechanism 60, which can enter the scanning path of the recording unit 4. In the following description, components similar to those in the first embodiment are denoted by the same reference numerals and their description is omitted.

[0071] (Paper switching mechanism) Referring to Figures 12(a) to (c), the paper-to-paper switching operation of the recording unit 9 using the engaging portion 63b of the lever member 63 will be described. Figures 12(a) to (c) are views of the recording unit 9 from the rear opposite to the side to which the recording head is attached. The recording unit 9 includes a carriage 91 that supports the recording head (not shown), a sliding member 93 attached to the carriage 91, an L-shaped guide rail 95 attached to the chassis 94, and a switching member 97 for adjusting the relative position of the carriage 91 and the sliding member 93. The recording head in this embodiment ejects liquid such as ink downward in the height direction (up and down direction in Figure 12(a)). The carriage 91 also scans in the left-right direction in Figure 12(a) integrally with the recording head.

[0072] Figure 12(a) shows the recording unit 9 as a carriage unit when it is in its normal position in the height direction. The recording unit 9 is in its normal position mainly when high quality is required for the recorded image and when recording is performed on a recording medium other than cardboard such as an envelope. In the normal position, the carriage 91's vertical position is determined by its own weight, with the sliding surface 91a facing downward in the height direction (in the direction of the horizontal arrow in Figure 12(a)) contacting the guide rail 95.

[0073] On the other hand, in the height direction, the downward-facing sliding surface 93a of the sliding member 93 is at a higher position than the sliding surface 91a of the carriage 91, so the sliding surface 93a does not come into contact with the guide rail 95. A biasing spring 99 is attached to the sliding member 93, and the sliding member 93 is in contact with the biasing spring 99. Therefore, it is biased upward in the height direction (in the direction of the diagonal arrow in Figure 12(a)). In addition, the sliding member 93 is positioned in the scanning direction relative to the carriage 91 at the location where the biasing spring 99 is attached, and is also positioned in the height direction by contacting the carriage 91. With this configuration, in the normal position, the sliding surface 93a of the sliding member 93 does not come into contact with the guide rail 95.

[0074] Furthermore, a switching member 97 is attached to the back of the carriage 91, between the carriage 91 and the sliding member 93. The switching member 97 has an elongated shape in the scanning direction and is configured to be movable in the scanning direction. The switching member 97 has a cam surface 97d formed on it, which acts as an adjustment cam that displaces the carriage 91 and the sliding member 93 in multiple stages relative to each other in the height direction.

[0075] With both ends 97a and 97b of the switching member 97 in the scanning direction abutting against the side surface of the chassis 94, the recording unit 9 is moved in the scanning direction, causing the switching member 97 to slide in the scanning direction relative to the carriage 91 and the sliding member 93. Furthermore, the switching member 97 is provided with a cylindrical engaging portion 97c, and can also slide when the engaging portion 97c abuts against the engaging portion 63b of the lever member 63. In the height direction, the switching member 97 is positioned by the carriage 91 in the upward direction and by the sliding member 93 in the downward direction.

[0076] Figure 12(b) shows the state in which the recording head is positioned higher than the normal position shown in Figure 12(b), the gap between the paper and the recording unit 9 is in the envelope position. When the recording medium is made of thick cardboard such as an envelope, or when the recording medium is made of a material that is very prone to curling, the recording unit 9 is switched from the normal position to the envelope position in order to widen the gap (paper gap) between the recording head and the recording medium.

[0077] When recording in the envelope position, the recording unit 9 collides the end 97b of the switching member 97 with the side of the chassis 94. This collision causes the switching member 97 to begin sliding relative to the carriage 91 and the sliding member 93 in the direction of the black arrow shown in Figure 12(b). Then, the sliding member 93 moves downward (in the direction of the diagonal arrow in Figure 12(b)) due to the cam surface 97d provided on the switching member 97. The sliding member 93 is then positioned vertically when its sliding surface 93a contacts the guide rail 95. Subsequently, the sliding member 93 attempts to move further downward due to the cam surface 97d, but is blocked by the guide rail 95. This reaction force is then transmitted via the cam surface 97d to the switching member 97 and the carriage 91 which restricts the upward movement of the switching member 97. As a result, the carriage 91 and the switching member 97 move upward (in the direction of the horizontal arrow in Figure 12). When the end 97b of the switching member 97 is pushed in to this extent, the switching member 97 comes into contact with the carriage 91 in the scanning direction and does not move any further in the scanning direction. With this configuration, the recording unit 9 is switched from the normal position to the envelope position. At this time, as the carriage 91 moves upward, the sliding surface 91a of the carriage 91 is separated from the guide rail 95. The carriage 91 is then positioned in the height direction relative to the guide rail 95 via the sliding member 93 and the switching member 97.

[0078] Figure 12(c) shows the state of the recording unit 9 with a wider paper-to-paper distance than the envelope position shown in Figure 12(b). As described above, the engaging portion 63b of the lever member 63 is configured to enter and retract from the scanning path of the recording unit 9 by the drive of the transport motor 31, which is the drive source. In this embodiment, when the engaging portion 63b enters the scanning path of the recording unit 9, the engaging portion 63b moves to a position where it can contact the engaged portion 97c of the switching member 97. Therefore, when the recording unit 9 is scanned from left to right in Figure 12(c) with the lever member 63 in the operating position and the engaging portion 63b positioned on the scanning path of the recording unit 9, the switching portion The material 97 comes into contact with the engaging portion 63b. The switching member 97 then moves relative to the carriage 91 and the sliding member 93, sliding in the direction of the black arrow in Figure 12(c). When the switching member 97 has slid to the state shown in Figure 12(c), the cam surface 97d of the switching member 97 increases the relative height distance between the carriage 91 and the sliding member 93. In other words, as shown in Figure 12(c), the movement of the switching member 97 is restricted by the engaging portion 63b, causing the carriage 91 to move upward (in the direction of the horizontal arrow) and the sliding member 93 to move downward (in the direction of the diagonal arrow). As the carriage 91 moves upward in the height direction, the recording head supported by the carriage 91 also moves upward in the height direction, increasing the distance between the papers.

[0079] Furthermore, when the recording unit 9 is brought into contact with the engaging unit 63b from right to left in the position shown in Figure 12(c), the switching member 97 slides in the opposite direction to the black arrow in Figure 12(c), and as a result, the recording unit 9 returns to the state shown in Figure 12(a). By providing the engaging unit 63b with such a configuration, further paper-to-paper switching operations can be performed on the recording unit 9.

[0080] As described above, according to this embodiment, by using in combination the operation of abutting the switching member 97 against the chassis 94 and the operation of abutting the switching member 97 against the lever member 63, it is possible to set the paper spacing position of the recording unit 9 to three or more locations. Furthermore, since the lever member 63 is prevented from swinging unintentionally from the operating position to the non-operating position due to external force, the paper spacing can be switched stably.

[0081] Furthermore, the application of the present invention is not limited to the configuration of the embodiments described above, and can be applied to other configurations as long as the identity of the invention is not lost. For example, the present invention can also be applied to a configuration in which a lever member for locking the carriage at the capping position and a lever member for switching between papers are provided separately, and each can enter and retract onto the scanning path of the recording means. In addition, the mechanism by which the rotating member swings the oscillating member is not limited to the configuration using the cam surface and link part described above, and can be modified in various ways.
