DETAILED DESCRIPTION

[0037] Hereinafter, the present invention will first be briefly described.

[0038] In order to solve the above technical problems, a first mode of the recording device of the present invention is characterized in that it comprises: a recording head, which is mounted on a reciprocating slide and records on a medium; a conveying roller, which conveys the medium; a discharge roller, which discharges the recorded medium; a medium receiving tray, which receives the medium discharged by the discharge roller and can adopt a first state and a second state displaced from the first state to the discharge direction of the medium; a motor, which serves as a power source for the discharge roller; a power transmission unit, which can adopt a power transmission state in which the power of the motor is transmitted from the motor to the medium receiving tray, and a power non-transmission state in which the power of the motor is not transmitted from the motor to the medium receiving tray; and a belt, which is hung on a conveying roller pulley provided on the conveying roller and a discharge roller pulley provided on the discharge roller, and the power transmission unit is located between the outer end of the conveying roller pulley and the outer end of the discharge roller pulley in the discharge direction.

[0039] According to this method, the power transmission part is located between the outer end of the conveying roller pulley and the outer end of the discharge roller pulley in the discharge direction. When the power transmission part is arranged at the front end side of the discharge direction relative to the discharge roller pulley, the device as a whole tends to protrude toward the front end side of the discharge direction, and when the power transmission part is arranged at the rear end side of the discharge direction relative to the conveying roller pulley, the device as a whole tends to protrude toward the rear end side of the discharge direction. However, by arranging the power transmission part in this way, the length of the recording device as a whole in the discharge direction can be shortened. Therefore, the recording device having a medium receiving tray that can be displaced between a first state and a second state can be miniaturized.

[0040] A recording device according to a second aspect of the present invention is an aspect dependent on the first aspect, and is characterized in that the power transmission portion is located closer to the center of the recording device in the reciprocating direction of the carriage than the belt winding range.

[0041] According to this embodiment, the power transmission part is located on the inner side closer to the center of the recording device in the reciprocating direction of the carriage than the belt winding range. When the power transmission part is located on the outer side of the recording device in the reciprocating direction of the carriage than the belt winding range, the entire device tends to protrude in the reciprocating direction of the carriage, but with such a structure, the entire length of the recording device in the reciprocating direction of the carriage can be shortened. Therefore, the recording device having a medium receiving tray that can be displaced between the first state and the second state can be particularly miniaturized.

[0042] A recording device according to a third aspect of the present invention is an aspect dependent on the first or second aspect, and is characterized in that the power transmission portion is located around the motor when viewed from a direction along the reciprocating direction of the carriage.

[0043] According to this aspect, when viewed from the direction along the reciprocating direction of the carriage, the power transmission part is located around the motor. That is, the power transmission part is arranged to bypass the motor. Therefore, interference between the power transmission part and the motor can be suppressed.

[0044] The recording device involved in the fourth mode of the present invention is characterized in that it comprises: a recording head, which is mounted on a reciprocating slide and records on a medium; a conveying roller, which conveys the medium; a discharge roller, which discharges the recorded medium; a medium receiving tray, which receives the medium discharged by the discharge roller and can adopt a first state and a second state displaced from the first state to the discharge direction of the medium; a motor, which serves as a power source for the discharge roller; a power transmission part, which can adopt a power transmission state in which the power of the motor is transmitted from the motor to the medium receiving tray, and a power non-transmission state in which the power of the motor is not transmitted from the motor to the medium receiving tray; and a switching lever part, which switches between the power non-transmission state and the power transmission state, the power transmission part having a power switching mechanism, the power switching mechanism switching between the power non-transmission state and the power transmission state through the switching lever part, and the power switching mechanism is located between the outer end of the motor and the outer end of the conveying roller in the discharge direction.

[0045] According to this method, the power transmission part has a power switching mechanism, and the power switching mechanism switches between a power non-transmission state and a power transmission state by switching the lever part, and the power switching mechanism is located between the outer end of the motor and the outer end of the conveying roller in the discharge direction. When the power switching mechanism is arranged on the front end side of the discharge direction compared with the outer end of the motor, the device as a whole tends to protrude toward the front end side of the discharge direction, and when the power transmission part is arranged on the rear end side of the discharge direction compared with the outer end of the conveying roller, the device as a whole tends to protrude toward the rear end side of the discharge direction, but by arranging the power switching mechanism in this way, the length of the recording device as a whole in the discharge direction can be shortened. Therefore, the recording device having a medium receiving tray that can be displaced between a first state and a second state can be miniaturized.

[0046] The recording device involved in the fifth mode of the present invention is a mode subordinate to the fourth mode, and is characterized in that the power switching mechanism overlaps with the motor in at least one of the reciprocating direction of the slide and the intersecting direction that intersects both the discharge direction and the reciprocating direction of the slide.

[0047] According to this method, the power switching mechanism overlaps with the motor in at least one of the reciprocating direction and the intersecting direction of the carriage. Therefore, the power switching mechanism can be efficiently arranged relative to the motor in at least one of the reciprocating direction and the intersecting direction of the carriage, and a recording device having a medium receiving tray that can be displaced between a first state and a second state can be particularly miniaturized.

[0048] The recording device involved in the sixth mode of the present invention is a mode subordinate to the fourth or fifth mode, and is characterized in that the power switching mechanism overlaps with the final stage of the driving wheel system of the power transmission part in an intersecting direction that intersects both the discharge direction and the reciprocating movement direction of the slide.

[0049] According to this method, the power switching mechanism overlaps with the last stage of the driving gear train of the power transmission unit in the intersecting direction intersecting both the discharge direction and the reciprocating direction of the carriage. Therefore, in the intersecting direction, the power switching mechanism can be efficiently arranged relative to the driving gear train of the power transmission unit, and a recording device having a medium receiving tray that can be displaced between a first state and a second state can be particularly miniaturized.

[0050] Below, according to Figures 1 to 28 A recording device 1 according to an embodiment of the present invention is described in detail. In the following description, three mutually orthogonal axes are respectively set as the X-axis, the Y-axis, and the Z-axis as shown in the respective figures. The Z-axis direction corresponds to the vertical direction, i.e., the direction in which gravity acts. The X-axis direction and the Y-axis direction correspond to the horizontal direction. In the respective figures, the directions indicated by the arrows of the three axes (X, Y, Z) are the + directions of the respective directions. For example, the X-axis direction corresponds to the reciprocating direction of the carriage 3, the +X direction corresponds to the side where the power transmission unit 100 is provided, and the -X direction corresponds to the initial position side of the carriage 3. In addition, the +Y direction corresponds to the discharge direction of the medium receiving tray 5.

[0051] like Figure 1 As shown, the recording device 1 of this embodiment includes a housing 2. A front cover 2a is provided as a part of the housing 2. The recording device 1 of this embodiment can be opened and closed from Figure 1 The left side of the figure is shifted as Figure 1 Specifically, the medium receiving tray 5 is configured by Figure 2 The motor 6 shown in the figure can switch between a first state that is a stored state and a second state that is an expanded state.

[0052] Here, the recording device 1 of this embodiment has the following inside the housing 2: Fig. 9 and Fig.10 The slide 3 reciprocates along the X-axis direction as shown in FIG. Fig.23 and Fig.24The recording head 4 is mounted on the carriage 3 and records on the medium. Figure 2 As shown in FIG. 1 and FIG. 2 , the housing 2 includes a conveying roller 7 for conveying the medium and a discharge roller 8 for discharging the recorded medium. In addition, the recording device 1 of this embodiment includes a medium receiving tray 5 inside the housing 2. Fig. 9 and Fig.10 As shown in FIG. 1 , receiving the medium discharged by the discharge roller 8; and the motor 6, as Figure 2 As shown in the figure, it serves as a power source for the conveying roller 7 and the discharging roller 8.

[0053] The power is transmitted from the motor 6 to the conveying roller 7 and the discharge roller 8 as follows. Figure 6 As shown, the motor 6 is equipped with a motor pulley 6a. A belt 10 is mounted on the motor pulley 6a. In addition to the motor pulley 6a, the belt 10 is also hung on the conveying roller pulley 7a provided on the conveying roller 7, the discharge roller pulley 8a provided on the discharge roller 8, and the pulley 9. The motor 6 also rotates the motor pulley 6a by rotating the rotating shaft, and the belt 10 rotates accordingly, and then the conveying roller 7 and the discharge roller 8 rotate with the rotation of the conveying roller pulley 7a and the discharge roller pulley 8a. It should be noted that, as Figure 7 and Fig.12 As shown in FIG. 1 and FIG. 2 , the transport roller 7 is provided with an encoder 7 b for measuring the rotation of the transport roller 7 .

[0054] Here, as described above, the medium receiving tray 5 can take a first state in which the medium is stored and a second state in which the medium is displaced from the first state in the direction of discharging the medium. Figure 2 Here, the power transmission unit 100 can take a power transmission state in which the power of the motor 6 is transmitted from the motor 6 to the medium receiving tray 5 , and a power non-transmission state in which the power of the motor 6 is not transmitted from the motor 6 to the medium receiving tray 5 .

[0055] Here, the power transmission unit 100 will be described. Figures 7 to 12As shown in the figures, the power transmission part 100 has a gear 101 engaged with the conveying roller pulley 7a. The gear 101 is engaged with the gear 102, and a locking part 103 as a D-type gear and a transmission part 104 as a gear are provided on the rotating shaft 102a of the gear 102. The rotating shaft 102a of the gear 102, the locking part 103 and the transmission part 104 are along the X-axis direction, and the locking part 103 and the transmission part 104 are configured to be able to move in the X-axis direction as a whole through the power switching mechanism 120. It should be noted that the details of the power switching mechanism 120 will be described later, but the locking part 103 is configured to not rotate due to interference with the holding member 123 constituting a part of the power switching mechanism 120, and the transmission part 104 is configured to rotate with the rotation of the gear 102.

[0056] In addition, if Figures 7 to 12 As shown in the figures, the power transmission part 100 includes a gear 105, and the locking part 103 and the transmission part 104 are moved in the X-axis direction by the power switching mechanism 120, so that the gear 105 can be engaged with the locking part 103, and the gear 105 can be engaged with the transmission part 104. It should be noted that according to the above structure, when the gear 102 rotates, the gear 105 does not rotate when the gear 105 is engaged with the locking part 103, and the gear 105 rotates when the gear 105 is engaged with the transmission part 104.

[0057] In addition, if Figures 7 to 12 As shown in the figure, the gear 105 is engaged with the gear 106, the gear 106 is engaged with the gear 107, the gear 107 is engaged with the gear 108, and the gear 108 is engaged with the gear 109. The gear 109 is engaged with the gear 110. The gear 110 is engaged with the gear 111 of the common rotating shaft via the friction forming part 112. In other words, the gear 110, the gear 111 and the friction forming part 112 constitute a friction gear. In addition, the gear 111 is engaged with the gear 113 of the last stage of the driving gear train of the power transmission part 100. The gear 113 is configured to be rotatable together with the pinion 114 of the common rotating shaft, and the pinion 114 is engaged with the rack 5a formed on the medium receiving tray 5, so that the medium receiving tray 5 can move along the Y-axis direction as the gear 113 rotates. Thus, the power transmission part 100 of this embodiment has the power switching mechanism 120 and the driving gear train from the gear 101 to the gear 113.

[0058] In the recording device 1 of this embodiment, as Figure 6As shown, the power transmission unit 100 is located in the area L1 between the outer end of the conveying roller pulley 7a and the outer end of the discharge roller pulley 8a in the Y-axis direction corresponding to the medium discharge direction. When the power transmission unit 100 is arranged on the front end side of the discharge direction than the discharge roller pulley 8a, the entire device is likely to protrude in the +Y direction, which is the front end side of the discharge direction. When the power transmission unit 100 is arranged on the -Y direction, which is the rear end side of the discharge direction than the conveying roller pulley 7a, the entire device is likely to protrude toward the rear end side of the discharge direction. However, by arranging the power transmission unit 100 in this way, the entire length of the recording device 1 in the discharge direction can be shortened. Therefore, the recording device 1 of this embodiment is miniaturized in the recording device having the medium receiving tray 5 that can be displaced between the first state and the second state.

[0059] In addition, if Figure 4 and Figure 5 As shown, the power transmission part 100 of this embodiment is located closer to the center of the recording device 1 in the X-axis direction corresponding to the reciprocating movement direction of the slide 3 than the winding range L2 of the belt 10, that is, Figure 4 and Figure 5 When the power transmission unit 100 is located on the outer side of the recording device 1 in the reciprocating direction of the carriage 3 relative to the pulling range of the belt 10, the entire device tends to protrude in the reciprocating direction of the carriage 3, but by adopting such a structure, the entire length of the recording device 1 in the reciprocating direction of the carriage 3 can be shortened. Therefore, the recording device 1 of this embodiment is particularly small in size among recording devices having the medium receiving tray 5 that can be displaced between the first state and the second state.

[0060] In addition, if Figure 6 As shown, the power transmission unit 100 of this embodiment is located around the motor 6 when viewed from the direction along the reciprocating direction of the carriage 3. In other words, the power transmission unit 100 is arranged to bypass the motor 6. Therefore, the recording device 1 of this embodiment suppresses interference between the power transmission unit 100 and the motor 6.

[0061] Next, the recording device 1 of this embodiment will be described from the viewpoint of the configuration of the power switching mechanism 120. The recording device 1 of this embodiment has a power switching mechanism 120 such as Figures 8 to 12 As shown, it has: a switching lever 121, which switches the power transmission part 100 to a power transmission state and a power non-transmission state; a cam 122, as shown Figure 3 As shown, there is a cam surface 122a; and a retaining portion 123, as shown Fig.11 The locking part 103 and the transmission part 104 are maintained as shown in FIG. Figure 3As shown in FIG. 1 , a pin 123a is arranged on the cam surface 122a. As will be described in detail later, the power switching mechanism 120 can switch between a power non-transmission state and a power transmission state by switching the lever portion 121. Figure 2 As shown, the power switching mechanism 120 is located in a region L3 between the outer end of the motor 6 and the outer end of the conveying roller 7 in the Y-axis direction corresponding to the medium discharge direction. It should be noted that the position of the power switching mechanism 120 can be set to, for example Figure 3 The contact position between the cam surface 122a and the pin 123a is shown as position S1.

[0062] When the power switching mechanism 120 is arranged on the front end side (+Y direction) of the discharge direction compared to the outer end of the motor 6, the entire device tends to protrude toward the front end side (+Y direction) of the discharge direction, and when the power transmission unit 120 is arranged on the rear end side (-Y direction) of the discharge direction compared to the outer end of the conveying roller 7, the entire device tends to protrude toward the rear end side (-Y direction) of the discharge direction. However, by arranging the power switching mechanism 120 in this way, the entire length of the recording device 1 in the discharge direction (Y-axis direction) can be shortened. Therefore, the recording device 1 of this embodiment is miniaturized in the recording device having the medium receiving tray 5 that can be displaced between the first state and the second state.

[0063] In addition, if Figure 3 As shown, the power switching mechanism 120 of this embodiment overlaps the occupied range L4 of the motor 6 at position S1 in the reciprocating direction (X-axis direction) of the carriage 3. Figure 2 As shown, the power switching mechanism 120 of this embodiment overlaps the occupied range L5 of the motor 6 at position S1 in the Z-axis direction corresponding to the intersecting direction intersecting both the discharge direction (Y-axis direction) and the reciprocating direction (X-axis direction) of the carriage.

[0064] Therefore, it is preferable that the power switching mechanism 120 overlaps with the motor 6 in at least one of the reciprocating direction (X-axis direction) and the intersecting direction (Z-axis direction) of the carriage 3. By adopting such a structure, the power switching mechanism 120 can be efficiently arranged relative to the motor 6 in at least one of the reciprocating direction (X-axis direction) and the intersecting direction (Z-axis direction) of the carriage 3, and the recording device having the medium receiving tray 5 that can be displaced between the first state and the second state can be particularly miniaturized.

[0065] In addition, if Figure 2As shown, the power switching mechanism 120 of the present embodiment overlaps the occupied range L6 of the gear 113 of the last stage of the driving gear train of the power transmission unit 100 at position S1 in the intersecting direction (Z-axis direction). The power switching mechanism 120 of the present embodiment adopts such a structure, so that the power switching mechanism 120 can be efficiently arranged in the intersecting direction (Z-axis direction) relative to the driving gear train of the power transmission unit 100. Therefore, the recording device 1 of the present embodiment having the medium receiving tray 5 that can be displaced between the first state and the second state can be particularly miniaturized.

[0066] Hereinafter, the relationship between the operation of the power transmission unit 100, in particular the operation of the switching lever 121 of the power switching mechanism 120, the operation of the drive train accompanying the power transmission unit 100, and the operation of the carriage 3 will be described. Figure 8 as well as Fig. 9 As shown in FIG. 1 and FIG. 2 , the switching lever 121 is provided in the reciprocating range A1 of the carriage 3 in the X-axis direction. The reciprocating range A1 of the carriage 3 refers to the area where the carriage 3 exists as the carriage 3 reciprocates. Fig. 9 and Fig.13 As shown in the figure on the right side of the figure, the contact position where the front end portion 121a as a part of the switching lever portion 121 can contact the slide 3 with the reciprocating movement of the slide 3, and Figure 8 and Fig.13 As shown in the figure on the left side of the figure, the carriage 3 moves but any part of the switching lever 121 does not contact the carriage 3. Specifically, the conveying roller 7 is rotated in the forward direction, i.e., the rotation direction when the medium is conveyed, by rotating the motor 6 in the forward direction. Fig.13 The switching lever 121 rotates in the rotation direction R1, and the switching lever 121 changes from the initial state Fig.13 The non-contact position of the left state transitions to Fig.13 It should be noted that, in the initial state, the switching lever portion 121 is urged in the rotation direction R2.

[0067] like Fig.13As shown, the switching lever 121 has a front end 121a that moves forward and backward within the reciprocating range A1 of the carriage 3 by rotating, and an engaging portion 121b that does not engage with the engaged portion 123b of the holding portion 123 in the non-contact position but engages with the engaged portion 123b of the holding portion 123 in the contact position. Here, the switching lever 121 is urged toward the -X direction by the elastic member 125, and the holding portion 123 is urged toward the -X direction by the coil spring 124. However, when the switching lever 121 is in the contact position, it contacts the carriage 3 and slides toward the +X direction as the carriage 3 reciprocates, so that the holding portion 123 slides toward the +X direction together with the switching lever 121. Furthermore, the holding portion 123 slides toward the +X direction together with the switching lever 121, so that the power transmission unit 100 switches between the power non-transmission state and the power transmission state.

[0068] Below, refer to Figure 3 , Fig.15 , Fig.16 as well as Fig. 20 , a procedure for switching the power transmission unit 100 from the power non-transmitting state to the power transmitting state will be described. Fig.14 , Fig.15 and Fig.16 Both show a case where the power transmission unit 100 switches from the power non-transmitting state to the power transmitting state. Fig.14 , Fig.15 and Fig.16 The upper left picture is Fig.13 The left side figure corresponds to the state where the switching lever 121 is in the initial state, that is, the non-contact position. It should be noted that in this state, the position of the pin 123a of the holding portion 123 relative to the cam surface 122a of the cam 122 becomes Figure 3 The first position P1 in.

[0069] Next, by rotating the motor 6 forward, Fig.14 , Fig.15 as well as Fig.16 The state of the upper left figure transitions to Fig.14 , Fig.15 as well as Fig.16 This corresponds to the state of the upper right figure. Fig.13 The state corresponding to the left side of the figure is Fig.13 Specifically, the switching lever 121 rotates in the rotation direction R1, the front end 121a enters the reciprocating range A1 of the carriage 3, and the engaging portion 121b engages with the engaged portion 123b. It should be noted that in this state, the position of the pin 123a of the retaining portion 123 relative to the cam surface 122a of the cam 122 also becomes Figure 3 The first position P1 in the. Here, Fig.14 , Fig.15 and Fig.16 The status of the upper left picture, and Fig.14 , Fig.15 and Fig.16 The state of the upper right figure is that the gear 105 is engaged with the locking part 103 and the power transmission unit 100 is in a power non-transmitting state.

[0070] Next, from Fig.14 , Fig.15 and Fig.16 In the state of the upper right figure, the front end portion 121a contacts the carriage 3 and presses the switching lever portion 121 in the +X direction, thereby transitioning to Fig.14 , Fig.15 and Fig.16 The state of the lower left figure. It should be noted that Fig.14 , Fig.15 and Fig.16 It should be noted that in this state, the position of the pin 123a of the holding portion 123 relative to the cam surface 122a of the cam 122 is Figure 3 The second position P2 in the middle. Move along the moving path D1 from the first position P1 to the second position P2. Figure 3 The second position P2 is formed with a pin holding portion 122b, which is held by hanging the pin 123a on the cam surface 122a. Fig.14 , Fig.15 and Fig.16 The state of the lower left figure is that the gear 105 is engaged with the transmission part 104, and the power transmission unit 100 is in the power transmission state. Fig. 20 As shown, in Fig.14 , Fig.15 and Fig.16 When the position of the pin 123a of the holding portion 123 shown in the state of the lower left figure is at the second position P2, the engaging portion 121b and the engaged portion 123b become a structure supported by the upper surface 126a of the support frame 126 of the gear 101. Therefore, the engagement and disengagement of the engaging portion 121b and the engaged portion 123b are suppressed.

[0071] Next, from Fig.14 , Fig.15 and Fig.16 In the state of the lower left figure, the front end portion 121a contacts the carriage 3, and the switching lever portion 121 is further pressed in the +X direction. Fig.14 , Fig.15 and Fig.16 It should be noted that in this state, the position of the pin 123a of the retaining portion 123 relative to the cam surface 122a of the cam 122 is Figure 3The third position P3 in the slide 3 is moved from the second position P2 to the third position P3 along the moving path D2. It should be noted that, at the third position P3, there is no structure for holding the pin 123a such as the pin holding portion 122b, so that as the slide 3 moves in the -X direction, the position of the pin 123a of the holding portion 123 relative to the cam surface 122a of the cam 122 returns to the first position P1 due to the force of the elastic member 125 acting in the -X direction. The slide 3 moves from the third position P3 to the first position P1 along the moving path D3.

[0072] By adopting such a structure, the recording device 1 of this embodiment can appropriately configure the power switching mechanism 120 or the switching lever 121 for switching the power transmission unit 100 between the power non-transmission state and the power transmission state, and can make the mechanism for switching the medium receiving tray 5 between the first state and the second state smaller as a whole. In addition, the recording device 1 can be made smaller as a whole.

[0073] In addition, as described above, the switching lever portion 121 of the recording device 1 of this embodiment is as shown in Fig. 9 , Fig.13 As shown in the figure on the right side of FIG. , at least the front end portion 121a enters the reciprocating movement range A1 of the carriage 3 at the contact position. Figure 8 , Fig.13 As shown in the left figure of FIG. 1 , the front end portion 121a is withdrawn from the reciprocating range A1 of the carriage 3 at the non-contact position. Thus, in the power non-transmitting state, the front end portion 121a is withdrawn from the reciprocating range A1 of the carriage 3 at the non-contact position, thereby eliminating the need to provide the switching lever portion 121 outside the reciprocating range A1 of the carriage 3, and making the recording device 1 particularly compact.

[0074] In addition, as described above, in the recording device 1 of the present embodiment, the power transmission unit 100 has: a locking part 103, such as Fig.14 and Fig.16 As shown in the upper right figure of the figure, the rotation of the gear is hindered when the power is not transmitted; and the transmission part 104, such as Fig.14 and Fig.16 As shown in the lower left figure of FIG. , the power of the motor 6 is transmitted when in the power transmission state. Fig.14 and Fig.16 The upper right picture and Fig.14 and Fig.16As can be seen from the lower left figure, the switching lever 121 slides in the +X direction by contacting the carriage 3, thereby switching the connection between the locking part 103 and the transmission part 104 in the power transmission part 100 and the gear 105. By adopting such a structure, the recording device 1 of this embodiment can simply form a mechanism for blocking the rotation of the gear when in the power non-transmission state and a mechanism for transmitting the power of the motor 6 when in the power transmission state. In addition, in the recording device 1 of this embodiment, when the medium receiving tray 5 is manually operated, Fig.21 and Fig. 22 The friction gear shown generates a load. The purpose of generating this load is to prevent the medium receiving tray 5 from moving due to its own weight when the recording device 1 is tilted during storage, etc., or to generate a manual operation feel. It should be noted that when power is transmitted, the connection between the locking part 103 and the transmission part 104 is switched, the gear train is unlocked, and the medium receiving tray 5 is driven by the motor power.

[0075] Here, the power transmission unit 100 is configured so that the user can switch the connection with the gear 105 from the locking part 103 to the transmission part 104 by manually applying an external load, in addition to applying an external load in the direction in which the switching lever 121 contacts and slides with the carriage 3, that is, in the +X direction. The recording device 1 of this embodiment adopts such a structure, so that the user can manually switch the power transmission state and the power non-transmission state, for example, when the power of the recording device 1 is turned off. In addition, the parts of the mechanism that allows the user to manually switch the power transmission state and the power non-transmission state can be reduced.

[0076] Here, refer to Figures 16 to 19 , the structure of the switching mechanism for connecting the locking part 103 to the transmission part 104 and the gear 105 in the power transmission unit 100 will be described. Figures 17 to 19 express Fig.16 , that is, the position of the pin 123a of the holding portion 123 relative to the cam surface 122a of the cam 122 is located at Figure 3 In addition, Fig.17 In order to facilitate understanding of the shape of the rotating shaft 102a of the gear 102, a compression spring 127 described later is omitted.

[0077] like Fig.18 and Fig.19 As shown in FIG. 1 , the area closer to the −X direction side than the center of the rotation axis 102a of the gear 102 is a cross shape 102b. Fig.19 As shown in FIG. 1 , the transmission part 104 is configured to have a cross-shaped hole portion, which is engaged with the cross-shaped hole 102b of the rotating shaft 102a. As the rotating shaft 102a rotates, the transmission part 104 always rotates. Fig.16 and Fig.17 As shown, the locking part 103 is provided with a circular hole for the rotation shaft 102a to pass through. Moreover, the locking part 103 is configured such that: the area opposite to the cross-shaped 102b of the rotation shaft 102a is Fig.16 In the upper left state, Fig.16 In the upper right state and Fig.16 In the lower left state, and the cylindrical area 102c opposite to the cross-shaped area 102b of the rotation axis 102a Fig.16 In any of the lower left states, the rotation axis 102a will not follow the rotation even if it rotates. Fig.17 As shown, the locking part 103 is configured such that a flange portion 103b described later is substantially D-shaped, and even if the rotating shaft 102a rotates and moves, the abutted portion 123c of the holding portion 123 and the flange portion 103b will not abut and move.

[0078] It should be noted that if Fig.18 As shown in the figures, a compression spring 127 is provided between the gear 102 of the rotating shaft 102a and the locking part 103, and the locking part 103 is urged by the compression spring 127 in a direction away from the gear 102, i.e., in the -X direction. Furthermore, the locking part 103 is provided with a tooth portion 103a on the -X direction side and a flange portion 103b in a substantially D shape on the +X direction side. Since such a compression spring 127 is provided, the locking part 103 is of such a structure that the teeth of both parties can be easily engaged even if the locking part 103 is temporarily meshed with the gear 105, thereby being properly positioned. Furthermore, by providing such a compression spring 127, when the locking part 103 is moved from the gear 105, the teeth of the two parties can be easily engaged with each other, thereby being properly positioned. Furthermore, by providing such a compression spring 127, when the locking part 103 is moved from the gear 105, the teeth of the two parties can be easily engaged with each other, thereby being properly positioned. Fig.16 The upper right state transitions to Fig.16 In the lower left state, the transmission part 104 is constructed so that even if it is temporarily meshed with the gear 105, for example, the teeth of both parties are easily engaged.

[0079] It should be noted that if Figure 3 As shown, the power switching mechanism 120 of the power transmission unit 100 includes a cam 122 having a cam surface 122a, a holding portion 123 that holds the locking part 103 and the transmission part 104 and is provided with a pin 123a on the cam surface 122a, but as described above, the pin 123a moves between the power non-transmission state and the power transmission state by moving the cam surface 122a in the first position P1, the second position P2, and the third position P3. The recording device 1 of this embodiment can be configured to be small by forming such a structure, and the recording device 1 can be particularly small.

[0080] In addition, if Figure 3As shown, the cam surface 122a is provided with a flat surface portion 122c, which is the position where the pin 123a is located when the power transmission unit 100 is in a power non-transmission state, that is, when the pin 123a is located at a position other than the second position P2 of the cam surface 122a. In addition, the cam surface 122a is provided with a pin holding portion 122b, which holds the pin 123a when the power transmission unit 100 is in a power transmission state, that is, when the pin 123a is located at the second position P2 of the cam surface 122a. By adopting such a structure, it is possible to suppress the position deviation of the pin 123a when the power transmission unit 100 is in a power transmission state.

[0081] Next, refer to Fig.21 and Fig. 22 The structure of the gear 110, the gear 111 and the friction forming part 112, that is, the friction gear composed of these will be described. Fig.21 and Fig. 22 As shown in FIG. 1 , the gear 110 is formed with a hook portion 110a on the -X direction side. Fig. 22 As shown, the gear 111 has an abutting portion 111a on the +X direction side that abuts against the wall portion 110b of the gear 110. When the abutting force of the abutting portion 111a against the wall portion 110b is strong, the gear 111 is easy to rotate together with the gear 110, and when the abutting force of the abutting portion 111a against the wall portion 110b is weak, the gear 111 slides relative to the gear 110, making it difficult to rotate together with the gear 110. Fig.21 and Fig. 22 As shown, a friction forming portion 112 as a compression spring is formed between the hook portion 110a and the contact portion 111a, and the contact force of the contact portion 111a with respect to the wall portion 110b is set to an appropriate contact force.

[0082] Next, refer to Fig.23 as well as Fig.24 The structure of the head forming surface 3a, which is the surface facing the switching lever portion 121 in the carriage 3, will be described. Fig.23 and Fig.24 1 shows the state when the carriage 3 is located at the most +X direction side in its reciprocating range A1. Specifically, the recording device 1 of this embodiment can repeatedly transport the medium being transported in the transport direction and transport the medium in the direction opposite to the transport direction, thereby suppressing the oblique transport of the medium, so-called deflection elimination. However, when deflection elimination is performed, the carriage 3 is arranged at Fig.23 and Fig.24 Here, when eliminating the deflection, as the conveying roller 7 rotates, the switching lever 121 also rotates, so that Fig.23 As shown, the head forming surface 3 a is in contact with the switching lever portion 121 .

[0083] The carriage 3 of this embodiment has a recording head 4, a medium width sensor 21, and a hole shape 22 on the head forming surface 3a. These components are sensitive components that may cause performance changes by contacting other components, and therefore correspond to non-permitted parts that are not allowed to contact the switching lever part 121. It should be noted that in the carriage 3 of this embodiment, as shown in FIG. Fig.23 As shown in the figure, the front end portion 121a of the switching lever portion 121 is arranged at a position opposite to the medium width sensor 21. Therefore, the carriage 3 of this embodiment is provided with a protection portion 3b for protecting the medium width sensor 21 around the medium width sensor 21 as a non-permitted portion. Moreover, the front end portion 121a of the switching lever portion 121 is configured to have a planar facing surface provided at a portion opposite to the protection portion 3b. Therefore, the recording device 1 of this embodiment can prevent the front end portion 121a from contacting the medium width sensor 21 as a non-permitted portion, for example, even if the front end portion 121a contacts the protection portion 3b.

[0084] It should be noted that, in this embodiment, the front end portion 121a of the switching lever portion 121 is arranged at a position opposite to the medium width sensor 21 as the non-permissible portion. Therefore, a protection portion 3b for protecting the medium width sensor 21 is provided around the medium width sensor 21. However, if the front end portion 121a of the switching lever portion 121 is arranged at a position opposite to the recording head 4 as the non-permissible portion, it is preferable to provide the protection portion 3b around the recording head 4, and if the front end portion 121a of the switching lever portion 121 is arranged at a position opposite to the hole shape 22 as the non-permissible portion, it is preferable to provide the protection portion 3b around the hole shape 22.

[0085] Next, refer to Figure 25 to Figure 28 The installation structure of the power transmission unit 100 is described. Figure 25 to Figure 27 As shown, the power transmission unit 100 is sandwiched between a first frame 131 having a plurality of gear support portions 131a and a second frame 132 in the X-axis direction to form a unit 130. Then, the unit 130 is used Fig.28 It is shown that the discharge roller 8 is placed on the placement portion 141 of the main frame 140 to which the discharge roller 8 is attached and fixed.

[0086] That is, the recording device 1 of the present embodiment includes a main frame 140 on which the discharge roller 8 is mounted, and the power transmission unit 100 is separate from the main frame 140 and is provided in a unit 130 that can be attached to and detached from the main frame 140. By adopting such a structure, the recording device 1 of the present embodiment can easily install the power transmission unit 100 inside the recording device 1, and can easily perform replacement or cleaning of the power transmission unit 100.

[0087] The present invention is not limited to the above-mentioned embodiments, and can be implemented by various structures within the scope of its purpose. In order to solve part or all of the above-mentioned technical problems, or to achieve part or all of the above-mentioned effects, the technical features in the embodiments corresponding to the technical features in each mode recorded in the content of the invention can be appropriately replaced or combined.
