JP 2004-345307 A

In the recording apparatus described in Patent Document 1, the inventors of the present applicant have examined that the tank mounting portion is provided in the second housing, and found that the following problems occur.
That is, when the second housing is rotated by a purpose other than the attachment / detachment of the tank (for example, internal maintenance work), the tank is mounted on the tank mounting part (although it exists in the tank mounting part, This is a problem that occurs when the tank is not mounted). As a result, the tank moves in the tank mounting portion in conjunction with the rotation of the second housing, and as a result, the tank and the tank mounting portion collide. The adverse effect of damaging the tank and the tank mounting part is expected. Furthermore, even when the user mounts the tank on the tank mounting portion with the second housing rotated to the separation position, it is expected that the tank and the tank mounting portion are similarly damaged.

  Accordingly, an object of the present invention is to provide a recording apparatus that suppresses an impact between a tank and a tank mounting portion.

  A recording apparatus according to the present invention is connected to a tank mounting portion in which a tank for storing a recording agent for recording an image on a recording medium is mounted, a first housing, and the first housing via a shaft. When the image is recorded on a recording medium in the vicinity of the first housing by the rotation, the position is close to the first housing. The tank mounting portion can be spaced apart from the first housing, and the tank mounting portion is arranged such that the mounting direction of the tank with respect to the tank mounting portion is a direction including a vertically downward direction at the spaced position. And a second housing provided. The tank mounting portion is a force different from the dynamic friction force that the tank receives from the inner surface of the tank mounting portion when the second housing is in the separated position, and is opposite to the mounting direction. There is provided a resistance applying mechanism that applies a direction resistance to the tank to be mounted.

  According to this, even when the tank is mounted on the tank mounting portion when the second housing is in the separated position, the tank has a resistance force in addition to the dynamic friction force between the tank and the inner surface of the tank mounting portion. Therefore, the impact between the tank and the tank mounting portion can be suppressed. Therefore, the tank and the tank mounting part are not easily damaged.

  In the present invention, a contact capable of detecting contact with the tank is provided at a downstream end of the tank mounting portion in the mounting direction, and the resistance applying mechanism is more than the contact with respect to the mounting direction. It is preferable to apply the resistance to the tank upstream. Thereby, it becomes possible to suppress the breakage of the contact.

  Moreover, in this invention, it is preferable that the said resistance-applying mechanism is arrange | positioned in the position adjacent to the said contact. Thereby, it becomes possible to suppress damage of the contact more reliably.

  Further, in the present invention, the resistance applying mechanism includes a protruding position that protrudes from the inner surface of the tank mounting portion when the second casing is in the separated position, and the second casing is in the proximity position. It is preferable to have a moving body that moves between the tank mounting portion and a retracted position that does not protrude from the inner surface. Thereby, since the moving body is in the protruding position when the second housing is in the separation position, it is possible to stop the movement of the tank in the mounting direction. In addition, since the moving body is in the retracted position when the second casing is in the proximity position, tank mounting is facilitated when the second casing is in the proximity position.

  Further, in the present invention, the resistance applying mechanism includes an urging portion that urges the moving body toward the protruding position, and when the second housing rotates from the separated position to the close position. It is preferable to have an engaging portion that engages with the moving body so as to move the moving body from the protruding position to the retracted position against the urging by the urging section. Accordingly, the moving body can be reliably moved to the protruding position and the retracted position in conjunction with the rotation of the second housing.

  In the present invention, the resistance applying mechanism may be configured such that the movable body is held at the protruding position against the urging by the urging portion when the second housing is in the separated position. Thus, it is preferable to have a restricting portion that restricts the movement of the moving body. This makes it possible to reliably stop the movement of the tank in the mounting direction when the second housing is at the separation position.

  In the present invention, the inclined surface that inclines from the top of the moving body toward the upstream side in the mounting direction at the protruding position is an inclined surface that inclines from the top of the mobile body toward the downstream side in the mounting direction. It is preferable that the angle with respect to the inner surface is larger than that. This makes it possible to more reliably stop the movement of the tank in the mounting direction when the second housing is at the separation position. In addition, the resistance when the tank is removed from the tank mounting portion is reduced.

  Moreover, in this invention, it is preferable that the said resistance-force provision mechanism is comprised from the elastic body. This simplifies the configuration of the resistance applying mechanism.

  The present invention further includes a support unit that supports the recording medium, and a recording unit that records an image using a recording agent on the recording medium supported by the support unit. The first casing supports the support section, and the second casing is arranged so that the recording section faces the support section when the second casing is in the proximity position. It is preferable to support the recording unit. As a result, when the second housing is in the separated position, the maintenance work for removing the jammed recording medium between the recording unit and the support unit, the maintenance operation for the recording unit, and the maintenance operation for the support unit are performed by the user. Can be made.

  According to the recording apparatus of the present invention, even if the tank is mounted on the tank mounting portion when the second housing is in the separated position, the tank is subjected to the dynamic frictional force between the tank and the inner surface of the tank mounting portion. Therefore, it is possible to suppress the impact between the tank and the tank mounting portion. Therefore, the tank and the tank mounting part are not easily damaged.

FIG.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

  First, an overall configuration of an inkjet printer 1 as an embodiment of a recording apparatus according to the present invention will be described with reference to FIGS.

  The printer 1 has an upper casing 1a and a lower casing 1b that are both rectangular parallelepiped shapes and substantially the same size. The upper housing (second housing) 1a has an open bottom surface, and the lower housing (first housing) 1b has an open top surface. The upper housing 1a overlaps the lower housing 1b and seals the opening surfaces of each other, thereby defining the space inside the printer 1 (see FIG. 2). A paper discharge unit 31 is provided on the top plate of the upper housing 1a. In a space defined by the upper and lower housings 1a and 1b, a paper transport path along which the paper P is transported along a thick arrow shown in FIG. Is formed.

  As shown in FIG. 2, the upper housing 1a is connected to the lower housing 1b via a shaft 1h extending in the main scanning direction on one side of the lower end thereof. And the upper housing | casing 1a can be rotated with respect to the lower housing | casing 1b centering on the said axis | shaft 1h. The upper housing 1a is rotated so as to be close to the lower housing 1b (the position shown in FIG. 2) and the separated position (shown in FIG. 1) farther from the lower housing 1b than the close position. Position). When the upper casing 1a is in the separated position, a part of the sheet transport path formed by the upper casing 1a and the lower casing 1b in the close position is exposed to the outside, and the user's work space is on the sheet transport path. Is secured. When the upper housing 1a is located at the separated position and a work space is secured, it becomes possible to perform jam processing and maintenance work of the recording unit 9 and the support unit 60. The jam processing is an operation in which the user removes the paper P jammed in the paper transport path during the recording operation. The maintenance work of the recording unit 9 includes a work for the user to remove foreign matters attached to the ejection surface 10a, a work for the user to adjust the mounting position of the head 10, and a work for the user to replace the head 10. The maintenance work of the support unit 60 includes a work for the user to remove foreign matter attached to the support surface 61a, a work for the user to adjust the mounting position of the support part 60, and a work for the user to replace the support part 60. . In addition to the maintenance work for the recording unit 9 and the support unit 60, the maintenance work includes components (feed roller 21, guide 29, feed roller pair 22) housed in the upper housing 1a and the lower housing 1b. To 28) cleaning work and replacement work are also included. The shaft 1h is provided with a spring (not shown) that urges the upper housing 1a in a direction to open the upper housing 1a (from the proximity position toward the separation position). In the present embodiment, the upper housing 1a can be opened to an inclination angle of approximately 35 degrees with respect to the horizontal plane.

  On the front surface of the upper housing 1a (the surface on the left front side in FIG. 1), there is provided a lock mechanism 70 that restricts the rotation of the upper housing 1a at the close position. On the front surface of the lower housing 1b, an openable / closable lid 1d that covers the front surface of the upper housing 1a is provided. The lid 1d rotates around a shaft 1g (see FIG. 2) provided at the lower end to open and close the front surface of the upper housing 1a. The lock mechanism 70 and the two cartridges 35 are exposed by opening the lid 1d. When rotating the upper casing 1a from the proximity position to the separation position, first, the user opens the lid 1d, releases the restriction by the lock mechanism 70, and then rotates the upper casing 1a. On the other hand, when returning to the original position, the user returns the upper casing 1a from the separated position to the close position, and then restricts the rotation of the upper casing 1a with the lock mechanism 70 and closes the lid 1d.

  The upper housing 1a includes two heads 10 (a precoat head 10 that discharges a pretreatment liquid and an inkjet head 10 that discharges black ink in order from the upstream side in the sheet conveyance direction indicated by a thick arrow in FIG. 2). 10 and the frame 3 that supports the upper roller of the feed roller pair 24, two cartridges 35 respectively mounted on two cartridge mounting portions (tank mounting portions) 80 formed on the upper housing 1a, and each portion of the printer 1 The control apparatus 1p (refer FIG. 2) which controls operation | movement of this is accommodated. In the present embodiment, the recording unit 9 that records an image on the paper P is configured by the two heads 10 and the frame 3. The two heads 10 are held on the upper housing 1 a via the frame 3.

  Further, the upper housing 1a is arranged along the upper roller of the feed roller pair 25, 26, the upper guide of the guide 29 between the roller pair 25, 26, the feed roller pair 27, 28, and the sheet conveying direction. Two sets of guides 29 between the feed roller pairs 26 and 28 are also accommodated. That is, when the upper housing 1a is rotated from the close position to the separated position, all of these housing components move together with the upper housing 1a. In FIG. 2, illustration of some components housed in the upper housing 1a is omitted.

  The lower housing 1b accommodates (holds) the support portion 60 and the paper feeding unit 1c. Further, the lower housing 1b accommodates a sheet sensor 32, feed roller pairs 22, 23, and two sets of guides 29 between the paper feed unit 1c and the feed roller pair 23 along the paper transport direction.

  Each cartridge (tank) 35 stores a pretreatment liquid or black ink (hereinafter, collectively referred to as “liquid”) as a recording agent supplied to the corresponding head 10. The pretreatment liquid is a liquid having a function of preventing ink bleeding and back-through and a function of improving ink color development and quick drying.

  The cartridge 35 has a substantially rectangular parallelepiped outer shape. As shown in FIG. 3C, the liquid supply unit 36 and the contact point 37 are provided on the front surface 35 a that is the downstream surface of the cartridge 35 in the mounting direction of the cartridge 35 with respect to the cartridge mounting unit 80. The liquid supply unit 36 and the contact point 37 are arranged side by side in the main scanning direction. The liquid supply part 36 is comprised from elastic members, such as rubber | gum, which seals the opening formed in the front surface 35a. When the cartridge 35 is attached to the cartridge attachment portion 80, a hollow needle 86 described later penetrates the liquid supply portion 36 (that is, an elastic member), and the head 10 corresponding to the cartridge 35 is connected to the hollow needle 86. They are connected via a tube (not shown) and a pump (not shown). Thus, the liquid in the cartridge 35 is supplied to the head 10. Each pump is driven by the control device 1p only when liquid is forcibly sent to the corresponding head 10 (that is, when purge operation or initial introduction of liquid is performed). Further, since a negative pressure is generated in the flow path in the head 10 during image recording, the liquid in the cartridge 35 is automatically supplied to the head 10. In this embodiment, the contact point 37 of the cartridge 35 is a contact point of an IC chip in which liquid information (for example, the type and amount of liquid) of the cartridge 35 is stored. It may be a contact point for supplying.

  Each head 10 is a line type long in the main scanning direction, and has a substantially rectangular parallelepiped outer shape. The two heads 10 are supported by the frame 3 so as to be separated from each other in the sub-scanning direction. Further, each head 10 is supported by the frame 3 so as to face the support portion 60 at an interval suitable for recording when the upper housing 1a is in the close position. A joint to which a tube connected to the hollow needle 86 is attached is provided on the upper surface of each head 10. In addition, a large number of discharge ports are opened in the discharge surface 10a on the lower surface of each head 10, and a flow path is formed in each head 10 until the liquid supplied from the cartridge 35 reaches the discharge port. Yes.

  The paper feed unit 1 c includes a paper feed tray 20 and a paper feed roller 21. Among these, the paper feed tray 20 can be attached to and detached from the lower housing 1b in the sub-scanning direction. The paper feed tray 20 is a box that opens upward, and can accommodate a plurality of types of paper P. The paper feed roller 21 is rotated under the control of the control device 1p, and feeds the paper P at the uppermost position of the paper feed tray 20. The paper P sent out by the paper feed roller 21 is guided by the guide 29 and sent to the support unit 60 while being sequentially sandwiched by the feed roller pairs 22 and 23.

  The support unit 60 is disposed to face the recording unit 9 in the vertical direction. The support unit 60 includes two platens 61 that face the head 10, and a frame 11 that supports the platens 61. The frame 11 rotatably supports the lower feed roller 24.

  The platen 61 has a size slightly larger than the ejection surface 10a in the main scanning direction and the sub-scanning direction, and is disposed to face each other in the vertical direction.

  The surface of the platen 61 is a support surface 61a that supports the paper P while facing the ejection surface 10a. The material and processing are devised so that the paper P can be held. For example, by forming a weakly adhesive silicon layer on the support surface 61a or by forming a large number of ribs along the sub-scanning direction, the sheet P placed on the support surface 61a is prevented from floating. The The platen 61 is made of resin.

  In the present embodiment, when the control device 1p receives a recording command from an external device, based on the recording command, a paper feed motor (not shown) for the paper feed roller 21 and a feed motor for each of the feed roller pairs 22-28. (Not shown) or the like is driven. The paper P sent out from the paper feed tray 20 is sent to the support unit 60 through the guide 29. The paper P sent to the support unit 60 is conveyed while being sandwiched between the pair of feed rollers 23, 24, and 25 supported by the support surface 61a and rotating. When the paper P sequentially passes directly under the two heads 10, each head 10 is driven under the control of the control device 1p, and liquid is ejected from the ejection port of each ejection surface 10a toward the surface of the paper P. Thus, an image is formed on the paper P. The liquid discharge operation from the discharge port is performed under the control of the control device 1p based on the detection signal from the paper sensor 32. The sheet P is then guided upward by the guide 29 and conveyed upward while being sandwiched by the pair of feed rollers 26, 27, 28, and is discharged from the opening 30 formed in the upper portion of the upper housing 1a to the paper discharge unit 31.

  During this recording operation, the control device 1p can detect the occurrence of a jam (the jam of the paper P in the paper transport path). Specifically, the occurrence of a jam is detected by the control device 1p based on signals from the paper sensor 32 and the drive motors of the feed roller pairs 22 to 28. When a jam occurs during the recording operation, the control device 1p controls the head 10, each motor, etc., and interrupts the recording operation itself. Then, the user opens the lid 1d and releases the restriction by the lock mechanism 70 to rotate the upper housing 1a in order to perform jam processing (operation to clear the jam of the paper P in the paper transport path). . The user removes the jammed paper P in the work space formed between the upper and lower casings 1a and 1b, and then returns the upper casing 1a to the close position. Thereafter, the lock mechanism 70 restricts the rotation of the upper casing 1a and closes the lid 1d. Thus, the jam handling operation is completed. Thereafter, the control operation 1p again receives a recording command from the external device, whereby the recording operation is started.

  Next, the cartridge mounting portion 80 will be described with reference to FIGS.

  As shown in FIGS. 1 and 2, two cartridge mounting portions 80 are provided on the upper portion of the upper housing 1a. These cartridge mounting portions 80 are arranged side by side in the main scanning direction, as shown in FIGS. As shown in FIG. 3A, the two cartridge mounting portions 80 are formed symmetrically with respect to a straight line L (two-dot chain line) in the vertical direction passing through the middle of both in the main scanning direction. Since each cartridge mounting unit 80 has the same configuration, one cartridge mounting unit 80 will be described below.

  As shown in FIG. 3, the cartridge mounting portion 80 has a concave portion 81 in which a substantially rectangular parallelepiped cartridge 35 can be mounted. The opening 81b of the recess 81 is an insertion port into which the cartridge 35 is inserted, and is formed on the front surface of the upper housing 1a. The recess 81 extends from the opening 81b toward the downstream side in the mounting direction of the cartridge 35 to the cartridge mounting portion 80. Thus, the mounting direction of the cartridge 35 to the cartridge mounting portion 80 is the horizontal direction (see FIG. 3B) when the upper housing 1a is in the close position, and is vertical when the upper housing 1a is in the separated position. The direction includes a downward component (see FIG. 3C). In the mounting direction of the cartridge 35 to the cartridge mounting portion 80, a contact 83 and a hollow needle 86 are provided on the bottom 82 which is a downstream surface of the recess 81. The contact 83 and the hollow needle 86 are arranged side by side in the main scanning direction. The contact 83 is electrically connected to the contact 37 (see FIG. 3C) when the cartridge 35 is completely mounted in the recess 81. Here, the state in which the cartridge 35 is completely attached to the recess 81 is a state in which the cartridge 35 is located at the arrangement position of the cartridge 35 when the liquid supply unit 36 is penetrated by the hollow needle 86. In the present embodiment, the contact 83 is made of an IC substrate. As a modification, the contact 83 may be a contact that is electrically connected to a contact that supplies power to a sensor or the like provided in the cartridge 35, for example. The hollow needle 86 is formed so as to protrude from the bottom 82 along the mounting direction of the cartridge 35. The hollow needle 86 is connected to a tube (not shown) connected to the head 10. The hollow needle 86 passes through the liquid supply unit 36, so that the head 10 facing the cartridge 35 is connected.

  As shown in FIG. 3, a penetrating portion 84 is formed in the cartridge mounting portion 80 at a position adjacent to the contact 83 and the hollow needle 86. The penetrating portion 84 opens on the lower inner surface 81 a of the recess 81. A resistance applying mechanism 90 is provided in the penetrating portion 84 of the cartridge mounting portion 80. The resistance applying mechanism 90 includes a swing member 91, an engaging portion 95, a spring 92, and the like. The penetrating portion 84 is arranged at a position overlapping the hollow needle 86 in the mounting direction of the cartridge 35 to the cartridge mounting portion 80. That is, the resistance applying mechanism 90 is arranged at a position overlapping the hollow needle 86 in the mounting direction of the cartridge 35 to the cartridge mounting portion 80.

  As a modification, the penetrating portion 84 may open on the left and right or upper inner surfaces other than the inner surface 81 a of the recess 81, and the resistance applying mechanism 90 may be provided there.

  The swing member 91 is swingably supported by a shaft 89 provided in the penetrating portion 84 and extending in the main scanning direction. The penetrating portion 84 is provided on the inner surface 81a upstream of the contact 83 and the tip of the hollow needle 86 in the mounting direction. That is, the swinging member 91 is arranged so that a resistance force can be applied to the cartridge 35 upstream of the contact 83 and the tip of the hollow needle 86 in the mounting direction. As shown in FIG. 3B, the swing member (moving body) 91 includes a horizontal portion 91a that extends horizontally along the sub-scanning direction when the upper housing 1a is in the close position, and a horizontal portion. An inclined portion 91b extending obliquely downward from one end of 91a has an “L” shape. The upper surface of the horizontal portion 91a constitutes a part of the inner surface of the recess 81 when the upper housing 1a is in the close position.

  One end of a coil spring (biasing portion) 92 is fixed to the lower end portion (end portion far from the shaft 89) of the inclined portion 91b. The other end of the spring 92 is fixed to a flange 93 formed on the lower surface of the cartridge mounting portion 80. As a result, the swing member 91 is urged clockwise by the spring 92 in FIG. In the present embodiment, a coil spring is employed as the urging portion, but any elastic member may be employed as long as it can be urged in the same direction. The spring 92 is also supported by the upper housing 1a.

  A protruding portion 97 is formed at the lower end of the inclined portion 91b. A stopper 94 is formed in the upper casing 1a in the vicinity of the inclined portion 91b. The protrusion 97 and the stopper 94 constitute a restricting portion 96 that restricts the swing range of the swing member 91. That is, when the upper housing 1a is rotated to the separated position, even if the swinging member 91 is rotated by the biasing force of the spring 92, the protruding portion 97 and the stopper 94 resist the biasing of the spring 92. Abut. By this contact, the rotation range of the swing member 91 is restricted, and the horizontal portion 91a is held at the protruding position (described later). As a result, the swing member 91 is positioned at the protruding position without being excessively rotated by the spring 92, and the cartridge 35 moves in the mounting direction at the cartridge mounting portion 80 when the upper housing 1a is at the separation position. It becomes possible to stop this reliably.

  As shown in FIG. 1, the engaging portions 95 are respectively formed at the upper ends of the two frames 1 e constituting the lower housing 1 b. As shown in FIG. 3B, the engaging portion 95 is formed so as to face the penetrating portion 84 when the upper housing 1a is in the close position. The engaging portion 95 has an inclined surface 95a that engages with the inclined portion 91b when the upper housing 1a is in the close position. Further, when the upper housing 1a rotates from the separated position to the close position, the engaging portion 95 engages with the inclined portion 91b to rotate the swinging member 91 counterclockwise in FIG. 3B. Move.

Next, the operation of the resistance applying mechanism 90 will be described.
The resistance applying mechanism 90 is interlocked with the rotation of the upper casing 1a. That is, when the upper housing 1a is in the close position, the swing member 91 of the resistance applying mechanism 90 is biased by the spring 92, but the inclined portion 91b and the engaging portion 95 are engaged. Therefore, the rotation of the swing member 91 is restricted. For this reason, the swing member 91 is disposed at a retracted position where the tip of the horizontal portion 91a does not protrude into the recess 81, that is, does not protrude from the inner side surface 81a.

  When the upper housing 1a is rotated from the close position to the separated position, the swinging member 91 supported by the upper housing 1a is separated from the engaging portion 95 as shown in FIG. And the inclined portion 91b are disengaged. Thereby, the swinging member 91 is rotated by the biasing force of the spring 92, and the horizontal portion 91a of the swinging member 91 is disposed at the protruding position protruding from the inner side surface 81a. At this time, since the protruding portion 97 and the stopper 94 abut as described above, the horizontal portion 91a is reliably positioned at the protruding position. At this time, the inclined surface 91d inclined from the top end 91c of the horizontal portion 91a toward the upstream side in the mounting direction is more inclined than the inclined surface 91e inclined from the top end portion 91c of the horizontal portion 91a toward the downstream side in the mounting direction. The angle with respect to the inner surface 81a is large. When the upper housing 1a is in the separated position, the movement of the cartridge 35 in the mounting direction can be more reliably stopped. In addition, when the cartridge 35 is extracted from the cartridge mounting portion 80, the surface facing the inner surface 81a of the cartridge 35 is not easily caught by the inclined surface 91e, and the extraction resistance of the cartridge 35 is reduced.

  When the upper housing 1a is rotated from the separation position toward the proximity position, the lower end of the inclined portion 91b first comes into contact with the inclined surface 95a of the engaging portion 95. Then, as the upper housing 1a approaches the proximity position, the inclined portion 91b is pushed by the inclined surface 95a. When the upper housing 1a reaches the close position, the swing member 91 is positioned at the retracted position by engaging with the engaging portion 95. That is, the engaging portion 95 engages with the inclined portion 91b against the bias of the spring 92 so as to move the swinging member 91 from the protruding position to the retracted position. Thus, the swing member 91 can selectively take the protruding position and the retracted position in accordance with the rotation of the upper housing 1a.

  Thus, in the present embodiment, the swing member 91 is positioned at the retracted position only when the upper housing 1a is at the close position. At this time, even if the cartridge 35 is mounted on the cartridge mounting portion 80, the cartridge 35 can be mounted on the cartridge mounting portion 80 without being caught by the swing member 91. When the upper housing 1a is in the proximity position, the mounting direction of the cartridge 35 to the cartridge mounting portion 80 is parallel to the horizontal direction (sub-scanning direction). For this reason, the cartridge 35 can be mounted on the cartridge mounting portion 80 by an arbitrary mounting force by the user. Accordingly, the cartridge 35 is mounted on the cartridge mounting portion 80 without damaging the cartridges 35 and the cartridge mounting portion 80 without causing a large impact on the contacts 37 and 83, the liquid supply portion 36 and the hollow needle 86. Is possible.

  On the other hand, in the state where the front end of the cartridge 35 in the mounting direction is inserted into the recess 81 of the cartridge mounting portion 80, when the upper casing 1a is rotated from the close position to the separated position, the upper casing 1a is rotated. In conjunction with this, the cartridge 35 moves obliquely downward, that is, in a direction including vertically downward with respect to the cartridge mounting portion 80. When the cartridge 35 is inserted into the recess 81 of the cartridge mounting portion 80 in a state where the upper housing 1a is in the separated position, the cartridge 35 is mounted on the cartridge mounting portion 80 as shown in FIG. The direction is an obliquely downward direction, that is, a direction including a vertically downward direction.

  At this time, in a state where the upper housing 1a is at the separation position, the swing member 91 is positioned at the protruding position. For this reason, even if the cartridge 35 moves vigorously along the mounting direction from the position indicated by the two-dot chain line, for example, as shown in FIG. That is, until the cartridge 35 is completely mounted, the tip of the swing member 91 disposed at the protruding position and the cartridge 35 come into contact with each other, and the swing force 91 stops the movement of the cartridge 35 (the cartridge 35). And a force other than kinetic friction caused by contact with the left and right and upper and lower inner surfaces of the recess 81 and a force in the direction opposite to the mounting direction) is applied. At this time, the impact force due to the contact between the cartridge 35 and the swing member 91 is smaller than the impact force when the cartridge 35 is moved to the position where the cartridge 35 is completely mounted. Therefore, the cartridge 35 and the swing member 91 are not damaged by contact. Since the movement of the cartridge 35 is stopped, it is possible to prevent the cartridges 35 and the cartridge mounting portion 80 from being damaged without applying a large impact to the contacts 37 and 83, the liquid supply unit 36, and the hollow needle 86. It becomes.

  As described above, according to the printer 1 according to the present embodiment, even when the upper housing 1a is rotated from the close position to the separated position when the cartridge 35 is in the middle of being mounted to the cartridge mounting portion 80, Even when the cartridge 35 is mounted on the cartridge mounting portion 80 when the upper housing 1a is in the separated position, the swing member 91 is applied to the cartridge 35 in addition to the dynamic frictional force between the cartridge 35 and the inner side surface 81a. The resistance by is given. For this reason, it is possible to suppress the impact between the cartridge mounting portion 80 and the cartridge 35. Therefore, the cartridge mounting portion 80 and the cartridge 35 are not easily damaged.

  Here, by rotating the upper housing 1a from the proximity position to the separation position, the work space for the user is secured as described above. When the upper housing 1a is located at the separated position and a work space is secured, it becomes possible to perform jam processing and maintenance work of the recording unit 9 and the support unit 60. That is, the user rotates the upper housing 1a from the close position to the separated position in order to perform jam processing and maintenance work of the recording unit 9 and the support unit 60. It does not rotate 1a. That is, the rotation of the upper housing 1a is performed for a purpose other than the insertion / extraction of the cartridge 35. Therefore, when the cartridge 35 is in the middle of being mounted on the cartridge mounting portion 80, when the user rotates the upper housing 1a from the close position to the separated position, or when the upper housing 1a is in the separated position, There may be a case where the user tries to mount the cartridge 35 on the cartridge mounting portion 80. In the present embodiment, since the impact between the cartridge mounting portion 80 and the cartridge 35 can be suppressed, the cartridge mounting portion 80 and the cartridge 35 are not easily damaged.

  The swing member 91 is disposed upstream of the contact 83 and the tip of the hollow needle 86 with respect to the mounting direction. For this reason, it is possible to apply a resistance force to the cartridge 35 upstream of the contact 83 and the tip of the hollow needle 86. Therefore, breakage of the contact 83 and the hollow needle 86 can be suppressed.

  Here, in the present embodiment, the contact 83 and the contact 37 of the cartridge 35 are electrically connected to each other. If deformation occurs in the contact 83 and the contact 37 that are electrically connected, there is a possibility that the connection cannot be made. However, since the impact between the cartridge 35 and the cartridge mounting portion 80 is mitigated by the resistance applying mechanism 90, the deformation of the contact 37 and the contact 38 can be suppressed, so that damage to the cartridge 35 and the cartridge mounting portion 80 can be suppressed. It becomes possible.

  Further, if the swing member is disposed at a position farther from the contact 83 and the hollow needle 86 than the center of the recess 81 in the main scanning direction, the cartridge 35 is located when the upper housing 1a is at the separated position. Is mounted in the recess 81, the cartridge 35 may rotate around the contact point between the cartridge 35 and the swinging member and contact the contact 83 and the hollow needle 86. However, in the present invention, the swing member 91 is disposed at a position adjacent to the contact 83 and the hollow needle 86 in the main scanning direction. For this reason, it becomes possible to suppress damage to the contact 83 and the hollow needle 86 more reliably.

  Since the resistance applying mechanism 90 includes the swing member 91 that can take the retracted position and the protruding position, the movement of the cartridge 35 in the mounting direction can be stopped. Since the swing member 91 is in the retracted position when the upper casing 1a is in the close position, the cartridge 35 can be easily mounted when the upper casing 1a is in the close position.

  Further, since the resistance applying mechanism 90 includes a spring 92 that biases the swing member 91 and an engaging portion 95 that engages with the swing member 91, the resistance applying mechanism 90 is interlocked with the rotation of the upper casing 1a. Thus, the swing member 91 can be reliably moved to the protruding position and the retracted position.

  In addition, since the recording unit 9 is supported by the upper casing 1a and the support unit 60 is supported by the lower casing 1b, the recording unit 9 and the supporting unit are rotated by rotating the upper casing 1a from the proximity position to the separation position. The maintenance work for removing the paper P jammed with the printer 60, the maintenance work for the recording unit 9, and the maintenance work for the support unit 60 can be performed by the user.

  As a modification, a resistance applying mechanism 290 as shown in FIG. 4 may be employed. As shown in FIG. 4A, the resistance applying mechanism 290 in the present modification is provided on the bottom 82 of the recess 81 of each cartridge mounting portion 80, respectively. Each resistance applying mechanism 290 has two elastic bodies 291 arranged along the main scanning direction.

  The elastic body 291 has a spring 292 disposed in a circular hole 82 b formed in the bottom portion 82, and a columnar portion 293 fixed to the spring 292. The diameter of the cylindrical portion 293 is slightly smaller than the diameter of the hole 82b. The cylindrical portion 293 is attached by a spring 292 so that a part of the cylindrical portion 293 protrudes from the hole 82b (the position shown in FIG. 4B) when the cartridge 35 is not attached to the cartridge attachment portion 80. It is energized. The distal end of the cylindrical portion 293 is disposed upstream of the distal end of the hollow needle 86 in the mounting position in the protruding position.

  In this configuration, even if the upper housing 1a is in the separated position and the cartridge 35 moves vigorously along the mounting direction in the recess 81 of the cartridge mounting portion 80, the front surface 35a of the cartridge 35 and the tip of the elastic body 291 Abut. At this time, the impact in the mounting direction of the cartridge 35 is absorbed by the spring 92. That is, the elastic body 291 provides a resistance force that stops the movement of the cartridge 35 while reducing the impact force. As a result, a large impact is not applied to the contacts 37 and 83, the liquid supply unit 36, and the hollow needle 86, and the cartridge 35 and the cartridge mounting unit 80 can be prevented from being damaged. Thereafter, the user can attach the cartridge 35 to the cartridge attachment portion 80 by pushing the cartridge 35 with a force larger than the urging force of the spring 292. In this modification, the cartridge 35 can be mounted on the cartridge mounting portion 80 while suppressing the impact between the cartridge mounting portion 80 and the cartridge 35 regardless of whether the upper housing 1a is in the separated position or the close position. Moreover, in this modification, since the two elastic bodies 291 constitute the resistance applying mechanism 290, the structure itself is simple. Note that the resistance applying mechanism 290 of the present modification may be composed of one elastic body 291. In this case, the elastic body 291 is preferably disposed at a position adjacent to the contact 83 and the hollow needle 86.
