[0008] The present disclosure will be described below based on embodiments. In each figure, the same reference numerals are used for the same components, and redundant descriptions may be omitted. As used herein, "same," "identical," and "simultaneous" do not mean exactly the same.

[0009] For example, in this specification, when "same," "identical," or "simultaneous" is used, it includes cases where measurement errors are taken into consideration. Also, for example, when "same," "identical," or "simultaneous" is used, it includes cases where manufacturing variations of the components are taken into consideration.

[0010] In this specification, the terms "same," "identical," and "simultaneous" include cases where they are the same to the extent that their function is not impaired. Therefore, for example, "the dimensions of both are the same" means that, taking into account measurement errors and manufacturing variations of the components, the difference between the two dimensions is within ±5 percent of the dimension of one, and particularly preferably within ±3 percent.

[0011] In each figure, X, Y, and Z represent three mutually orthogonal spatial axes. In this specification, the directions along these axes are referred to as the X-axis direction, Y-axis direction, and Z-axis direction. When specifying directions, a positive direction is denoted as "+" and a negative direction as "-", and positive and negative signs are used in the direction notation. In each figure, the direction pointed to by the arrow is described as the + direction, and the opposite direction of the arrow is described as the - direction.

[0012] The Z-axis direction indicates the direction of gravity, the +Z direction indicates vertically upward, and the -Z direction indicates vertically downward. A plane containing the X and Y axes is described as the XY plane, a plane containing the X and Z axes is described as the XZ plane, and a plane containing the Y and Z axes is described as the YZ plane. The XY plane is the horizontal plane. The three spatial axes X, Y, and Z, which are not limited to positive and negative directions, are described as the X-axis, Y-axis, and Z-axis.

[0013] The X-axis direction is horizontal along the installation surface, which is the horizontal plane on which the recording device 1 is installed. The X-axis direction is the width direction of the recording device 1, and is the width direction of the recording medium P. The Y-axis direction is horizontal along the installation surface on which the recording device 1 is installed. The Y-axis direction is the depth direction of the recording device 1, and is the direction along the transport direction of the recording medium P.

[0014] The +Y direction is the direction from the back to the front of the recording device 1, and the -Y direction is the direction from the front to the back of the recording device 1. In this embodiment, of the sides that make up the perimeter of the recording device 1, the side in the +Y direction becomes the front of the recording device 1, and the side in the -Y direction becomes the back of the recording device 1.

[0015] The side in the +X direction is the left side of the recording device 1, and the side in the -X direction is the right side of the recording device 1. The Z-axis direction is the normal direction to the installation surface on which the recording device 1 is installed, and is the height direction of the recording device 1.

[0016] In the following explanation, the direction in which the medium P is sent may be referred to as "downstream," and the opposite direction as "upstream." For illustrative purposes, the dimensions of each component may differ from those of the actual components.

[0017] <Embodiment> The schematic configuration of the recording device 1 according to this embodiment will be described along the transport path through which the medium P is transported. As shown in Figures 1 and 2, the recording device 1 comprises a main body 11 having a recording unit 40 (see Figure 2) for recording on the medium P. The recording device 1 comprises a cassette 2 on the bottom surface 11b side, which is in the -Z direction from the center of the main body 11.

[0018] As shown in Figures 2 and 3, the cassette 2 is provided on the main body 11 so as to be detachable from the side 11f, which is the side of the main body 11 in the +Y direction. In this embodiment, the side 11f is the front surface of the main body 11. The cassette 2 comprises a storage section 2a and a cover 2c. The storage section 2a houses the medium P. As shown in Figures 1 and 2, the cover 2c is positioned on the side 11f of the main body 11, which is in the +Y direction of the storage section 2a, and constitutes a part of the outer casing of the main body 11.

[0019] As shown in Figure 2, a delivery roller 3 driven by a motor M3 is provided above the housing section 2a of the cassette 2. The delivery roller 3 is movable forward and backward relative to the medium P housed in the housing section 2a. By rotating in contact with the medium P housed in the housing section 2a, the delivery roller 3 delivers the medium P from the housing section 2a of the cassette 2 in the +Y direction.

[0020] In the main body 11, at a position downstream of the delivery roller 3, a feed roller 5 driven by a motor M5 and a separation roller 6 to which rotational torque is applied by a torque limiter (not shown) are provided.

[0021] The separation roller 6 of the present embodiment is provided on the cover 2c of the cassette 2. The medium P sent out from the storage portion 2a is separated by being nipped between the feed roller 5 and the separation roller 6, and is further sent downstream.

[0022] Downstream of the feed roller 5 and the separation roller 6, a reverse roller 8 driven by a motor (not shown) is provided. Around the reverse roller 8, a first nip roller 9 and a second nip roller 10 are provided.

[0023] The medium P is nipped between the reverse roller 8 and the first nip roller 9, and is further nipped between the reverse roller 8 and the second nip roller 10 and conveyed.

The medium P supported by the media support section 12 is transported towards the first transport roller pair 15 via a transport path S12 by a transport roller 13 driven by a motor (not shown). Rotational torque is applied to the separation roller 14 by a torque limiter (not shown).

[0027] The supply path C2 is the path through which the medium P, which is sent out from cassette 62 located below cassette 2, is transported toward the recording unit 40. The supply path C2 is provided on the +Y direction side of the housing unit 2a and extends upward in the +Z direction from the bottom surface 11b. For this reason, at least a portion of the supply path C2 is provided on the cover 2c of cassette 2.

[0028] The feeding path C2 is provided with a pair of intermediate rollers 24, which includes a drive roller 25 driven by a motor M25 and a driven roller 26 that can rotate under its own power. For this reason, the pair of intermediate rollers 24 and the motor M25 are provided on the cover 2c of the cassette 2.

[0029] The relay roller pair 24 is located below the discharge roller 3 and the feed roller 5. The relay roller pair 24 is positioned so as to overlap with the housing section 2a when viewed from the +Y direction side, which is the side 11f side of the main body section 11.

[0030] The medium P transported from the cassette 62 is conveyed towards the recording unit 40 via the supply path C2 by the relay roller pair 24. The drive roller 25 of the relay roller pair 24 is an example of a transport roller that conveys the medium P transported from below towards the recording unit 40.

[0031] A media detection unit 22 is provided upstream of the first transport roller pair 15. The control unit 90, which will be described later, can position the leading edge of the media P relative to the recording unit 40 based on the detection information from the media detection unit 22. In addition, for example, the control unit 90 can position the media P at the recording start position.

[0032] The recording unit 40 performs recording by ejecting ink onto the medium P from a plurality of nozzles 44 provided on the ejection surface 42a. Ink is an example of a liquid. The recording unit 40 is a so-called line head in which a plurality of ink ejecting nozzles 44 are arranged to cover the entire area in the width direction of the medium. The recording unit 40 is elongated in the width direction of the medium and is configured as a liquid ejection head that can record across the entire width of the medium without movement in the width direction of the medium.

[0033] The discharge surface 42a is the surface facing the medium P. The discharge surface 42a can also be called the liquid discharge surface or nozzle surface. The recording device 1 includes a liquid storage section (not shown). The ink discharged from the recording section 40 is supplied to the recording section 40 from the liquid storage section via a supply tube (not shown).

[0034] A counter portion 23 is provided at a position opposite the discharge surface 42a of the recording unit 40. The counter portion 23 supports the medium P. The support of the counter portion 23 by the medium P defines the gap between the medium P and the discharge surface 42a.

[0035] Downstream of the recording unit 40, a second transport roller pair 19 is provided. The second transport roller pair 19 comprises a drive roller 20 driven by a motor (not shown) and a driven roller 21 that can rotate under its own power. The recording medium P is sent downstream by the second transport roller pair 19.

[0036] A third pair of transport rollers 27 is provided downstream of the second pair of transport rollers 19, and a discharge roller pair 28 is provided further downstream of the third pair of transport rollers 27. The path between the third pair of transport rollers 27 and the discharge roller pair 28 constitutes a face-down discharge path. The recorded medium P is discharged to the discharge tray 29 by the discharge roller pair 28 with the most recent recorded surface facing downwards.

[0037] An extension unit 61 is detachably attached to the recording device 1 at a position below the bottom surface 11b of the main body 11. The extension unit 61 includes a cassette 62. Cassette 62 is an example of another cassette provided below cassette 2.

[0038] Cassette 62 is attached to the extension unit 61 so as to be detachable from the side 61f, which is the side of the extension unit 61 in the +Y direction (see Figure 4). In this embodiment, side 61f is the front of the extension unit 61. When the extension unit 61 is attached to the main unit 11, the recording device 1 is equipped with a plurality of cassettes 2, 62 for housing the media P.

[0039] The cassette 62 comprises a housing section 62a and a cover 62c. The housing section 62a houses the medium P. The cover 62c is positioned on the side 61f of the extension body 61 in the +Y direction of the housing section 62a, and constitutes part of the outer casing of the extension body 61.

[0040] In the extension unit 61, a delivery roller 63 driven by a motor M63 is provided at a position above the storage section 62a. The delivery roller 63 is movable forward and backward relative to the medium P stored in the storage section 62a. By rotating in contact with the medium P stored in the storage section 62a, the delivery roller 63 delivers the medium P from the storage section 62a of the cassette 62 in the +Y direction.

[0041] The medium P discharged from the storage section 62a is transported to the supply path C2 via the supply path S62 provided in the extension body 61. In the extension body 61, a supply roller 65 driven by a motor M65 and a separation roller 66 to which rotational torque is applied by a torque limiter (not shown) are provided downstream of the discharge roller 63.

[0042] In this embodiment, the separation roller 66 is provided on the cover 62c of the cassette 62. The medium P discharged from the storage section 62a is separated by nipping between the feeding roller 65 and the separation roller 66, and then sent downstream along the feeding path S62.

[0043] In addition to the supply path S62, the extension unit 61 includes a supply path C62 through which the medium P sent from the extension unit 71 (described later) is transported. The supply path C62 is, for example, the path through which the medium P sent from the cassette 72 located below the cassette 62 is transported toward the recording unit 40.

[0044] The supply path C62 is provided on the +Y side of the housing section 62a and extends upward in the +Z direction from the bottom surface 61b of the extension body 61. For this reason, at least a portion of the supply path C62 is provided on the cover 62c of the cassette 62.

[0045] The feeding path C62 is provided with a relay roller pair 67, which includes a drive roller 68 driven by a motor M68 and a driven roller 69 that can rotate under its own power. For this reason, the relay roller pair 67 and the motor M68 are provided on the cover 62c of the cassette 62.

[0046] The relay roller pair 67 is located below the delivery roller 63 and the feed roller 65. The relay roller pair 67 is positioned so as to overlap with the housing section 62a when viewed from the +Y direction. The medium P transported from the extension body 71, which includes the medium P transported from the housing section 72a of the cassette 72, is transported by the relay roller pair 67 towards the recording section 40 via the feed path C62. The drive roller 68 of the relay roller pair 67 is an example of a transport roller that transports the medium P transported from below towards the recording section 40.

[0047] When attached to the main body 11, the extension unit 61 is attached to the bottom surface 11b of the main body 11. The bottom surface 11b of the main body 11 is an example of a mounting area to which the extension unit 61 is attached.

The mounting portion 51 and the mounting portion 611 are located adjacent to each other in the Y-axis direction, for example, on the -Y side of the feed path C62 and the relay roller pair 67. The mounting portion 52 and the mounting portion 612 are located away from the mounting portion 51 and the mounting portion 611 in the -Y direction.

[0049] Mounting portion 51 is, for example, a circular recess provided on the bottom surface 11b. Mounting portion 52 is, for example, a track-shaped recess provided on the bottom surface 11b that is elongated in the Y-axis direction. Mounted portions 611 and 612 are, for example, cylindrical projections that protrude from the upper surface 61u of the extension body 61.

[0050] The position of the extension 61 relative to the mounting portion 51 is defined when the mounting portion 611 is fitted into the mounting portion 51. Furthermore, the position of the extension 61 relative to the bottom surface 11b is defined when the mounting portion 612 is fitted into the mounting portion 52.

[0051] When the extension unit 61 is attached to the main unit 11, the motors M63, M65, M68 of the extension unit 61, the sensor (not shown) for detecting the presence or absence of the medium P, etc., are electrically connected to the control unit 90 via an electrical connection part (not shown) between the main unit 11 and the extension unit 61.

[0052] An extension unit 71 can be detachably attached to the extension unit 61 at a position below the bottom surface 61b. The extension unit 71 is equipped with a cassette 72. Cassette 72 is an example of another cassette provided below cassette 2.

[0053] Cassette 72 is attached to the expansion unit 71 so as to be detachable from the side 71f, which is the side of the expansion unit 71 in the +Y direction (see Figure 5). In this embodiment, side 71f is the front of the expansion unit 71. When the expansion unit 71 is attached to the expansion unit 61, the recording device 1 is equipped with a plurality of cassettes 2, 62, 72 for housing the medium P.

[0054] The cassette 72 comprises a housing section 72a and a cover 72c. The housing section 72a houses the medium P. The cover 72c is positioned on the side 71f of the extension body 71 in the +Y direction of the housing section 72a, and constitutes part of the outer casing of the extension body 71.

[0055] In the extension unit 71, a delivery roller 73 driven by a motor M73 is provided above the housing section 72a of the cassette 72. The delivery roller 73 is movable forward and backward relative to the medium P housed in the housing section 72a. By rotating in contact with the medium P housed in the housing section 72a, the delivery roller 73 delivers the medium P from the housing section 72a of the cassette 72 in the +Y direction.

[0056] The medium P discharged from the storage section 72a is transported to the supply path C62 of the extension body 61 via the supply path S72 provided in the extension body 71. In the extension body 71, a supply roller 75 driven by a motor M75 and a separation roller 76 to which rotational torque is applied by a torque limiter (not shown) are provided downstream of the discharge roller 73.

[0057] In this embodiment, the separation roller 76 is provided on the cover 72c of the cassette 72. The medium P discharged from the storage section 72a is separated by nipping between the feeding roller 75 and the separation roller 76, and then sent downstream along the feeding path S72.

[0058] The extension unit 71 is equipped with a supply path C72 in addition to the supply path S72. The supply path C72 is the path through which the medium P, transported from below the cassette 72, is transported toward the recording unit 40.

[0059] The supply path C72 is provided on the +Y direction side of the housing section 72a and extends upward in the +Z direction from the bottom surface 71b of the extension body 71. For this reason, at least a portion of the supply path C72 is provided on the cover 72c of the cassette 72.

[0060] The feeding path C72 is provided with a pair of intermediate rollers 77, which includes a drive roller 78 driven by a motor M78 and a driven roller 79 that can rotate under its own power. The pair of intermediate rollers 77 and the motor M78 are located on the cover 72c of the cassette 72.

[0061] The relay roller pair 77 is located below the delivery roller 73 and the feed roller 75. The relay roller pair 77 is positioned so as to overlap with the storage section 72a when viewed from the +Y direction. The medium P, which is transported from below the cassette 72, is transported by the relay roller pair 77 towards the recording section 40 via the feed path C72. The drive roller 78 of the relay roller pair 77 is an example of a transport roller that transports the medium P, which is transported from below, towards the recording section 40.

[0062] When attached to the extension unit 61, the extension unit 71 is attached to the bottom surface 61b of the extension unit 61. The bottom surface 61b of the extension unit 61 is an example of a mounting area to which the extension unit 71 is attached. The bottom surface 61b is provided with mounting parts 613 and 614 for attaching the extension unit 71 to the extension unit 61.

[0063] The upper surface 71u of the extension body 71 is provided with mounting portions 711 and 712 that fit into mounting portions 613 and 614. The mounting portion 613 and mounting portion 711 are provided in the Y-axis direction, for example, adjacent to the feed path C72 and the relay roller pair 77 on the -Y direction side. The mounting portion 614 and mounting portion 712 are provided at a distance from the mounting portion 613 and mounting portion 711 in the -Y direction.

[0064] The mounting portion 613 is, for example, a circular recess provided on the bottom surface 61b.

[0070] Therefore, in the recording device 1 of this embodiment, it is possible to attach the extension unit 71 to the bottom surface 11b of the main unit 11, and it is possible to attach the extension unit 61 to the bottom surface 71b of the extension unit 71.

[0071] The recording device 1 includes a control unit 90. The control unit 90 includes a CPU (Central Processing Unit), although it is not shown in the figure. The control unit 90 includes a storage unit that includes RAM (Random Access Memory) and ROM (Read Only Memory), etc. Various programs for controlling the recording device 1 and the expansion units 61 and 71, which will be described later, are stored in the storage unit.

[0072] The control unit 90 may include one or more processors that perform various processes according to a program, one or more dedicated hardware circuits such as an Application Specific Integrated Circuit (ASIC), or a combination thereof. The Application Specific Integrated Circuit (ASIC) performs at least some of the various processes.

[0073] A processor includes a CPU and memory such as RAM and ROM. Memory stores program code or instructions configured to cause the CPU to perform processing. Memory, or computer-readable media, includes everything accessible by a general-purpose or dedicated computer.

[0074] The control unit 90 in Figures 2 and 3 is shown conceptually, and in reality, it is composed of a circuit board installed in a predetermined location on the recording device 1. The control unit 90 is electrically connected to each part of the recording device 1 and the extension units 61 and 71, and comprehensively controls the operation of each part.

[0075] For example, the control unit 90 controls the transport mechanism and the drive rollers 16 located upstream of the drive rollers 16 of the first transport roller pair 15. The transport mechanism located upstream of the drive rollers 16 includes the discharge rollers 3, 63, 73, the feed rollers 5, 65, 75, the drive rollers 25, 68, 78, etc.

[0076] As a result, the medium P is transported from cassettes 2, 62, and 72 to the recording unit 40 and the opposing unit 23. The control unit 90 controls the recording unit 40 to eject ink onto the medium P supported by the opposing unit 23. This records an image onto the medium P.

[0077] As described above, the recording device 1 and extension unit 61 according to this embodiment provide the following advantages.

[0078] The recording device 1 comprises a main body 11 having a recording unit 40 for recording on a medium P. The recording device 1 also comprises a cassette 2 detachably attached to the main body 11, the cassette 2 having a storage unit 2a for housing the medium P. The recording device 1 also comprises a delivery roller 3 for discharging the medium P from the storage unit 2a. The cassette 2 is provided with a drive roller 25 located below the delivery roller 3, which transports the medium P discharged from a cassette 62 located below the cassette 2 toward the recording unit 40.

[0079] This prevents the height dimension of the extension unit 61 on which the cassette 62 is installed from increasing. Therefore, it is possible to prevent the height dimension of the recording device 1 from increasing when the extension unit 61 is attached to the main unit 11.

[0080] The cassette 62 is detachably attached to an extension unit 61 that can be mounted on the main unit 11, and the main unit 11 has a bottom surface 11b on which the extension unit 61 is mounted. This allows the extension unit 61 to be easily attached to the main unit 11.

[0081] When viewed from the +Y direction side of the main body 11, the drive roller 25 is positioned to overlap with the housing 2a. This arrangement prevents the height dimension of the main body 11 from increasing due to the placement of the drive roller 25. Therefore, the height dimension of the recording device 1 can be prevented from increasing.

[0082] The motor M25 that drives the drive roller 25 is located in the cassette 2. This makes it easy to drive the drive roller 25.

[0083] Cassette 2 is removed from the +Y direction side of the main unit 11. This allows cassette 2 to be removed from the front side of the recording device 1.

[0084] The cassette 2 has a cover 2c on the +Y direction side of the housing section 2a, and the drive roller 25 is provided on the cover 2c. This allows the drive roller 25 to be driven easily.

[0085] The medium P is transported towards the recording unit 40 through the +Y direction side of the storage section 2a in the cassette 2. This allows for efficient transport of the medium P stored in the storage section 2a and the medium P transported from below the cassette 2 towards the recording unit 40.

[0086] The extension unit 61 is an extension unit 61 that can be attached to the main unit 11 which has a recording unit 40 that records on a medium P. The extension unit 61 is a cassette 62 that is detachably provided to the extension unit 61 and comprises a cassette 62 having a storage unit 62a for housing the medium P. The extension unit 61 is provided with a delivery roller 63 that delivers the medium P from the storage unit 62a. The cassette 62 is provided with a drive roller 68 located below the delivery roller 63, which transports the medium P delivered from a cassette 72 located below the cassette 62 toward the recording unit 40.

[0087] According to this, it is possible to suppress an increase in the height dimension of the extension unit 61.

[0088] The recording device 1 according to the above embodiment of this disclosure is based on having the configuration described above, but it is of course possible to make partial changes or omissions to the configuration without departing from the gist of this disclosure.

[0089] The extension units 61 and 71 according to the above embodiment of this disclosure are based on having the configuration described above, but it is of course possible to make partial changes or omissions to the configuration without departing from the gist of this disclosure.

[0090] The embodiments described above and other embodiments described below can be combined and implemented to the extent that they do not conflict with each other technically. Other embodiments are described below.

[0091] In the above embodiment, the side of the recording device 1 in the +Y direction does not have to be the front of the recording device 1. For example, the side of the recording device 1 in the +X direction may be the front of the recording device 1. In this case, side 11f is the right side of the main body 11, side 61f is the right side of the extension 61, and side 71f is the right side of the extension 71. Alternatively, the side of the recording device 1 in the -X direction may be the front of the recording device 1. In this case, side 11f is the left side of the main body 11, side 61f is the left side of the extension 61, and side 71f is the left side of the extension 71.

[0092] In the above embodiment, motors M25, M68, and M78 do not necessarily have to be provided on cassettes 2, 62, and 72. For example, motor M25 may be provided on the main body 11 so as to be able to drive the drive roller 25 when cassette 2 is mounted on the main body 11. For example, motor M68 may be provided on the extension 61 so as to be able to drive the drive roller 68 when cassette 62 is mounted on the extension 61. For example, motor M78 may be provided on the extension 71 so as to be able to drive the drive roller 78 when cassette 72 is mounted on the extension 71.

[0093] In the above embodiment, the separation rollers 6, 66, and 76 do not necessarily have to be provided on the cassettes 2, 62, and 72. In this case, the separation roller 6 may be provided on the main body 11 so as to be movable above the cassette 2 when the cassette 2 is removed from the main body 11. In this case, the separation roller 66 may be provided on the extension body 61 so as to be movable above the cassette 62 when the cassette 62 is removed from the extension body 61. In this case, the separation roller 76 may be provided on the extension body 71 so as to be movable above the cassette 72 when the cassette 72 is removed from the extension body 71.

[0094] In the above embodiment, the mounting portion 52 and the mounted portion 612 do not have to be located at a distance in the -Y direction from the mounting portion 51 and the mounted portion 611. For example, the mounting portion 51 and the mounted portion 611 are located adjacent to each other on the -Y direction side of the feed path C62 and the relay roller pair 67. In this case, for example, the mounting portion 51 and the mounted portion 611 are located at the +X direction ends of the main body 11 and the extension 61 from the center in the X direction.

[0095] In this case, for example, the mounting portion 52 and the mounted portion 612 may be located at a position away from the mounting portion 51 and the mounted portion 611 in the -X direction, and may be provided at the -X end from the center of the main body portion 11 and the extension body 61. In this case, the mounting portion 613 and the mounted portion 711, and the mounting portion 713 are located at the same position as the mounting portion 51 and the mounted portion 611 in the X-axis and Y-axis directions. In this case, the mounting portion 614 and the mounted portion 712, and the mounting portion 714 are located at the same position as the mounting portion 52 and the mounted portion 612 in the X-axis and Y-axis directions.

[0096] In the above embodiment, the extension 71 may be such that it can be attached to the extension 61 but cannot be attached to the main body 11. In this case, for example, the mounting portion 613 may have a different shape from the mounting portion 51, and the mounting portion 711 that fits into the mounting portion 613 may have a different shape from the mounting portion 611 that fits into the mounting portion 51. As a result, when the recording device 1 is equipped with extensions 61 and 71, the cassettes 2, 62, and 72 equipped in the recording device 1 are arranged from top to bottom in the order of cassette 2, cassette 62, and cassette 72.

[0097] In the above embodiment, multiple cassettes may be detachably provided on a single extension body. For example, a single extension body may be an extension body 61 with an extension body 71 attached to it. In this case, a single extension body is detachably provided from the +Y direction side with a cassette 62 on which a relay roller pair 67 and a part of the feed path C62 are provided, and a cassette 72 on which a relay roller pair 77 and a part of the feed path C72 are provided.
