Device having cover

Abstract

To reduce a risk that a cover opening amount is small when a cover is opened, and thus a desired opening amount cannot be ensured.SOLUTION: A device having a cover includes a housing 2, a cover 4, and a moving portion 5 that can move between a first position and a second position. The cover 4 has a first pressing portion 8 and a first biasing member 9 that press the moving portion 5 located at a first position, and a second pressing portion 10 and a second biasing member 11. When the cover 4 is in a closed state, a pressing force P1 that presses the moving portion 5 due to the first pressing portion 8 being biased by the first biasing member 9 is the same as a pressing force P2 that presses the moving portion 5 due to the second pressing portion 10 being biased by the second biasing member 11. When the cover 4 is in an open state, the second pressing portion 10 protrudes beyond the first pressing portion 8.SELECTED DRAWING: Figure 18

[0007] The present invention will first be briefly described below. In order to solve the above problems, a device having a cover according to a first aspect of the present invention includes a housing, a cover that opens and closes by rotating relative to the housing via a rotation axis, and a moving part that is provided inside the housing and is located at a first position when the cover is in a closed state and is movable to a second position different from the first position when the cover is in an open state, wherein the cover has a base end on the side closer to the rotation axis and a tip end on the side farther from the rotation axis, and is provided at a position closer to the base end than the tip end, and a first pressing part that presses the moving part that is located at the first position, and a second pressing part that presses the first pressing part when the cover is in the closed state. The cover has a first biasing member that biases the movable portion toward the movable portion, a second pressing portion that is provided at a position closer to the tip portion than the base portion and presses the movable portion located at the first position, and a second biasing member that biases the second pressing portion toward the movable portion when the cover is in the closed state, wherein when the cover is in the closed state, a pressing force with which the first pressing portion is biased by the first biasing member to press the movable portion is equal to a pressing force with which the second pressing portion is biased by the second biasing member to press the movable portion, and when the cover is in the open state, the second pressing portion protrudes further than the first pressing portion. Here, the term "bias" is used to mean applying an elastic force to an object by utilizing an elastic force obtained by an elastic body such as a spring or rubber. Furthermore, the word "same" in "the pressing force is the same" does not necessarily mean that they are strictly the same, but is used in a positive sense as long as they are the same to the extent that they satisfy the specifications of the posture that the moving part should take when the pressing force is applied to the moving part.

[0008] According to this aspect, when the cover is in the open state, the second pressing portion protrudes more than the first pressing portion. In other words, when the cover rotates about the rotation shaft as a fulcrum to change from the closed state to the open state, the second pressing portion located on the tip end side of the cover protrudes more than the first pressing portion located on the base end side of the cover. This makes it possible to ensure the opening amount of the cover when opening the cover. At the same time, the first pressing portion can be reliably pressed in when closing the cover. Furthermore, when the cover is in the closed state, the pressing force with which the first pressing portion presses the moving portion as a result of being urged by the first urging member is the same as the pressing force with which the second pressing portion presses the moving portion as a result of being urged by the second urging member. This allows both sides of the moving portion to be pressed by the same pressing force of the first pressing portion and the second pressing portion when the cover is closed. That is, the first pressing portion and the second pressing portion can evenly press two points on the moving portion, one near the pivot shaft and the other far from the pivot shaft.

[0009] A device having a cover of a second aspect of the present invention is an aspect dependent on the first aspect, and comprises a first holder that holds the first pressing portion and the first biasing member, a second holder that holds the second pressing portion and the second biasing member, a first regulating portion provided on the first holder, a second regulating portion provided on the second holder, a first regulated portion provided on the first pressing portion, and a second regulated portion provided on the second pressing portion, wherein when the cover is in the open state, the first regulated portion comes into contact with the first regulating portion to regulate movement of the first pressing portion in the protruding direction, and when the cover is in the open state, the second regulated portion comes into contact with the second regulating portion to regulate movement of the second pressing portion in the protruding direction, a length from the first regulated portion to a tip of the first pressing portion and a length from the second regulated portion to the tip of the second pressing portion are the same, and a position of the second regulating portion is located downstream in the protruding direction from a position of the first regulating portion. Here, the term "same" in "the lengths are the same" does not mean that the two lengths are strictly the same, but is used in a positive sense as long as the lengths are the same within a range in which the desired effect can be obtained.

[0010] According to this aspect, the length from the first restricted portion provided on the first pressing portion to the tip of the first pressing portion is the same as the length from the second restricted portion provided on the second pressing portion to the tip of the second pressing portion. Furthermore, the position of the second restricting portion provided on the second holder is located downstream in the protruding direction from the position of the first restricting portion provided on the first holder. This makes it possible to easily achieve, with a simple structure, the "pressing force of the first pressing portion and the pressing force of the second pressing portion are the same" and "when the cover is in the open state, the second pressing portion protrudes further than the first pressing portion" in the first aspect. Thus, the same effect as in the first aspect can be obtained. Moreover, by changing the position of the first restricting portion, the amount of protrusion of the first pressing portion from the first holder can be easily adjusted. Similarly, by changing the position of the second restricting portion, the amount of protrusion of the second pressing portion from the second holder can be easily adjusted.

[0011] A device having a cover of a third aspect of the present invention is an aspect dependent on the second aspect, and is characterized in that the first pressing portion and the second pressing portion are configured from the same part, and the first biasing member and the second biasing member are configured from the same part. Here, the term "same part" refers not only to parts that have the same structure when viewed from the front, back, top, bottom, left and right, but also to parts that are symmetrical with respect to one plane.

[0012] According to this aspect, the first pressing portion and the second pressing portion are configured from the same part, and the first biasing member and the second biasing member are configured from the same part. By standardizing the parts, manufacturing becomes easier and costs can be reduced.

[0013] A device having a cover of a fourth aspect of the present invention is an aspect dependent on any one of the first to third aspects, and is characterized in that it comprises a positioning pin for positioning the cover, and an insertion port into which the positioning pin is inserted when the cover is in the closed state. Here, the positioning pin may be provided on either the cover or the housing, and the insertion opening is provided on the one of the cover and the housing on which the positioning pin is not provided.

[0014] In the case where a device having a cover has a structure using the positioning pin, frictional force may be generated between the cover and the insertion port when the cover is opened. According to this aspect, even in such a structure, the cover can be opened reliably.

[0015] A device having a cover of a fifth aspect of the present invention is an aspect dependent on the fourth aspect, and is characterized in that the positioning pin and the insertion port are provided at a position opposite the rotation axis.

[0016] In a structure in which the positioning pin and the insertion opening are located on opposite sides of the pivot shaft, the cover has a tendency to sag at the tip end (free end) due to its own weight. In such a structure, when the positioning pin is inserted into the insertion opening and positioned, approximately half of the weight of the cover is placed on the positioning pin. Therefore, friction is particularly likely to occur between the positioning pin and the insertion opening. According to this aspect, the cover can be reliably opened even in such a structure.

[0017] A device having a cover of a sixth aspect of the present invention is an aspect dependent on any one of the first to third aspects, and is provided with a locking mechanism that locks the cover from rotating from the closed state to the open state, and the locking mechanism has an engaged portion provided on the housing, an engaging portion provided on the cover, and an operating portion provided on the cover, and is displaceable by operating the operating portion between a locked state in which the engaging portion engages with the engaged portion to lock the rotation of the cover, and an unlocked state in which the engagement between the engaging portion and the engaged portion is released, and when in the unlocked state, the first pressing portion and the second pressing portion protrude, causing the cover to rotate from the closed state to the open state.

[0018] According to this aspect, when the lock mechanism is in the unlocked state, the first pressing portion and the second pressing portion are biased by the first biasing member and the second biasing member, respectively, and thus protrude. This protrusion causes the cover to rotate from the closed state to the open state. As a result, when the lock mechanism is in the unlocked state, the cover automatically opens, improving user operability.

[0019] A device having a cover of the seventh aspect of the present invention is an aspect dependent on the fifth aspect, and is characterized in that it comprises a detectable member provided on the cover and a detection unit that detects opening and closing of the cover by detecting the detectable member, and the size of the protrusion of the second pressing portion is set so that when the cover is in the unlocked state, the detectable member rotates to a position where it is not detected by the detection unit.

[0020] According to this aspect, the size of the protrusion of the second pressing portion is set so that, when the cover is in the unlocked state, the detected member rotates to a position where it is not detected by the detection portion. As a result, when the cover is in the unlocked state, the cover opens against the frictional force between the positioning pin and the insertion opening, and the open state can be detected by the detection portion.

[0021] An eighth aspect of the device with a cover according to the present invention is an aspect dependent on the first aspect, and is characterized in that the device includes a recording unit that records on a medium and a transport unit that transports the medium, the transport unit being the transport unit, and the transport unit facing the recording unit when located at the first position. In other words, the device with a cover of this aspect is a recording device that includes the recording unit and the transport unit that is the transport unit. This aspect may be subordinate to any one of the second to seventh aspects.

[0022] According to this aspect, it is possible to stabilize the distance between the recording unit and the transport unit when the cover is in the closed state, while ensuring the amount of opening of the cover when the unlocked state is reached.

[0023] [Embodiment] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of an apparatus having a cover according to the present invention will be specifically described with reference to the drawings. In the following explanation, the three mutually orthogonal axes are referred to as the X-axis, Y-axis, and Z-axis, as shown in each figure. The directions indicated by the arrows on the three axes (X, Y, Z) are the + directions of each direction, and the opposite directions are the - directions. The Z-axis direction corresponds to the vertical direction, i.e., the direction in which gravity acts, the +Z direction indicates a vertical upward direction, and the -Z direction indicates a vertical downward direction. The X-axis and Y-axis directions correspond to the horizontal direction. The +Y direction indicates the front direction of the device, and the -Y direction indicates the rear direction of the device. The +X direction indicates the right direction of the device, and the -X direction indicates the left direction of the device.

[0024] <Apparatus with cover, recording apparatus> In this embodiment, the device 1 having a cover will be described as a recording device 100 such as an inkjet printer. As shown in FIG. 1, the recording device 100 is a device 1 with a cover, which is equipped with a cover 4 that can be opened and closed relative to a housing 2 (FIG. 2), a recording unit 33 (FIGS. 1 and 18) provided within the housing 2 for performing recording on a medium such as paper, a medium transport device including a transport unit 34 for transporting the medium stored in the medium storage unit 36 ​​along a transport path, and an output tray 37 onto which the medium on which recording has been performed by the recording unit 33 is discharged. Here, the transport unit 34 faces the recording unit 33 and is the moving unit 5 described below. The transport unit 34 is designed to maintain a constant distance from the recording unit 33 in order to ensure recording accuracy on the medium. In addition, the transport unit 34 is configured so that its upper part can swing in a direction away from the recording unit 33, with its lower part as a fulcrum, so that the medium can be removed if it becomes clogged in the transport path in the area of ​​the recording unit 33.

[0025] The operation of the recording unit 33 to record on the medium and the operation of the medium transport device to transport the medium are performed by a control unit (not shown). Here, the control unit includes a CPU, a flash ROM, and a RAM. The CPU performs various arithmetic processing according to programs stored in the flash ROM and controls the operation of the entire recording device 100. The flash ROM, which is an example of a storage means, is a non-volatile memory that can be read and written. Various information is temporarily stored in the RAM, which is an example of a storage means.

[0026] <Cover locking mechanism> 2 to 8 and 18, in this embodiment, the cover 4 opens and closes by rotating about the rotation shaft 3 relative to the housing 2. A lock mechanism 25 is provided to lock the cover 4 from rotating from a closed state (FIG. 1) to an open state (FIG. 2). Specifically, as shown in Figures 3 and 4, the locking mechanism 25 has an engaged portion 26 provided on the housing 2, an engaging portion 27 (Figures 5 and 6) provided on the cover 4, and an operating portion 28 (Figures 1 and 2) provided on the cover 4.

[0027] As shown in FIG. 3, the engaged portion 26 is fixed to a frame of the housing 2 (not shown). The engaging portion 27 is attached to the shaft 29 so as to rotate integrally with the shaft 29. As shown in FIG. 5 and FIG. 6, the shaft 29 is attached to a frame of the cover 4 (not shown) so as to be rotatable around the axis, i.e., around the Z axis. The engaging portion 27 is attached to the upper end and the lower end of the shaft 29, respectively. FIG. 3 and FIG. 4 show the upper end of the shaft 29. The operating portion 28 is attached to the upper end of the shaft 29. When the user operates to press the operating portion 28 shown in FIG. 1, the shaft 29 rotates around the axis. When the shaft 29 rotates around the axis, the engaging portion 27 rotates in the direction of the arrow 30 shown in FIG. 4 from the position shown in FIG. 3. FIG. 3 shows a locked state in which the engaging portion 27 is engaged with the engaged portion 26 and locked. FIG. 4 shows an unlocked state in which the engaging portion 27 is released from the engagement with the engaged portion 26. That is, by operating operation portion 28, lock mechanism 25 can be displaced between a locked state (FIG. 3) in which rotation of cover 4 is locked by engagement between engaging portion 27 and engaged portion 26, and an unlocked state (FIG. 4) in which engagement between engaging portion 27 and engaged portion 26 is released. When in the unlocked state, first pressing portion 8 (FIG. 14) and second pressing portion 10 (FIG. 16), which will be described later, protrude, causing cover 4 to rotate from the closed state to the open state.

[0028] <Locating pin and insertion port> 2 and 5 to 8, in this embodiment, there are provided a positioning pin 23 for positioning the cover 4, and an insertion opening 24 into which the positioning pin 23 is inserted when the cover 4 is in the closed state. Here, the positioning pin 23 is provided in the cover 4, and the insertion opening 24 is provided in the housing 2. The positioning pin 23 may be provided in the housing 2, and the insertion opening 24 may be provided in the cover 4. The positioning pin 23 and the insertion opening 24 are provided for positioning the cover 4 with respect to the housing 2 when the cover 4 rotates from the open state to the closed state. Here, positioning pin 23 is a cylinder with a truncated cone-shaped tip. Insertion port 24 is a circular hole shape corresponding to the cylindrical shape of positioning pin 23. The inner diameter of insertion port 24 and the outer diameter of positioning pin 23 are formed to be the same dimension within a range in which the positioning effect can be obtained. The positioning pin 23 and the insertion port 24 are provided at a position opposite the rotation shaft 3. Here, as shown in Fig. 2, the positioning pin 23 is provided at the lower inside of the tip portion 7 of the cover 4. The insertion port 24 is provided at a position corresponding to the positioning pin 23 of the housing 2, i.e., at a position corresponding to the tip portion 7 of the cover 4.

[0029] <Detection of cover open / close status> 6 to 8, this embodiment includes a detectable member 31 provided on the cover 4, and a detector 32 that detects the opening and closing of the cover 4 by detecting the detectable member 31. The detectable member 31 is provided in the vicinity of the lower side of the positioning pin 23, at a height position overlapping with the engaging portion 27 in the Z-axis direction (FIGS. 5 and 6).

[0030] 6 shows a state immediately before the positioning pin 23 of the cover 4 enters the insertion opening 24 of the housing 2. The detected member 31 is located away from the detection unit 32. Fig. 7 shows a state in which the cover 4 has been further rotated and the positioning pin 23 has been inserted into the insertion opening 24. The detected member 31 is still separated from the detection unit 32. The arrow 35 in Fig. 7 indicates that the detection unit 32 swings. Fig. 8 shows that the cover 4 has been further rotated to the closed state (Fig. 1). The detectable member 31 is in a position where it can be detected by the detection unit 32. The detection unit 23 is pushed from above by the detectable member 31 and is in a state where it is swung in the direction of the arrow 35 (Fig. 7). In this state, the detection unit 32 detects that the cover 4 is in the closed state, and sends the detection result to the control unit. The device 1 having the cover recognizes that the cover 4 is in the closed state. Furthermore, in this closed state, the locking mechanism 25 is in the locked state.

[0031] When the operating portion 28 of the locking mechanism 25 is operated to change the locked state to the unlocked state, the first pressing portion 8 (FIG. 14) and the second pressing portion 10 (FIG. 16) described below protrude, causing the cover 4 to rotate from the closed state to the open state. Specifically, the state changes from that shown in Fig. 8 to that shown in Fig. 7. That is, the detected part 31 moves away from the position detected by the detection part 32. As a result, the detection part 32 detects that the cover 4 has changed from a closed state to an open state, and sends the detection result to the control part. The device 1 having the cover receives the detection result and recognizes that the cover 4 is in the open state.

[0032] <First pressing unit, second pressing unit, moving unit> 2 and 14 to 21, the device 1 with a cover of this embodiment includes a housing 2, a cover 4 that opens and closes by rotating about a rotation shaft 3 relative to the housing 2, and a moving section 5 provided inside the housing 2. As described above, in this embodiment, the moving section 5 is a transport unit 34 located opposite the recording section 33, and the upper part can swing around the lower part as a fulcrum. That is, the moving section 5 is located at a first position (FIG. 13) when the cover 4 is in a closed state, and is movable to a second position (FIGS. 11 and 12) different from the first position when the cover 4 is in an open state.

[0033] The cover 4 has a first pressing portion 8 and a first biasing member 9. The first pressing portion 8 is provided at a position closer to the base end 6 than the tip end 7, assuming that the side of the cover 4 closer to the rotation shaft 3 is the base end 6 and the side farther from the rotation shaft 3 is the tip end 7, and presses the moving portion 5 located at the first position (FIG. 13) toward the recording portion 33. The first biasing member 9 biases the first pressing portion 8 toward the moving portion 5 when the cover 4 is in the closed state. Here, the term "bias" is used to mean that an elastic force is applied to the first pressing portion 8, which is an object, by utilizing an elastic force obtained by an elastic body such as a spring or rubber. Here, a coil spring is used as the first biasing member 9. The cover 4 further has a second pressing portion 10 and a second biasing member 11. The second pressing portion 10 is provided at a position closer to the tip portion 7 than the base portion 6 of the cover 4, and presses the moving portion 5 located at the first position (FIG. 13) toward the recording portion 33. The second biasing member 11 biases the second pressing portion 10 toward the moving portion 5 when the cover 4 is in the closed state. Here, the meaning of "bias" is the same as described above.

[0034] Furthermore, when the cover 4 is in the closed state (FIG. 1), a pressing force P1 (FIG. 15) that presses the moving part 5 when the first pressing part 8 is biased by the first biasing member 9, and a pressing force P2 (FIG. 17) that presses the moving part 5 when the second pressing part 10 is biased by the second biasing member 11, are configured to be the same. Furthermore, when the cover 4 is in the open state, the second pressing part 10 is configured to protrude further than the first pressing part 8. Here, the pressing forces P1 and P2 being "the same" does not require that the pressing forces P1 and P2 are strictly the same, but may be the same within a range that satisfies the specifications of the posture that the moving part 5 should take when the pressing forces P1 and P2 are applied to the moving part 5.

[0035] 9 and 19 to 21, the moving part 5 is provided with a pressed part 41 against which the tip 18 of the first pressing part 8 comes into contact and receives a pressing force P1 when the cover 4 changes from the open state to the closed state. Furthermore, the moving part 5 is provided with a pressed part 42 against which the tip 19 of the second pressing part 10 comes into contact and receives a pressing force P2. 19 and 20, the tip 18 of the first pressing portion 8 and the pressed portion 41 are formed so as to be able to come into compact contact with each other when the cover 4 rotates about the rotation shaft 3 as a rotation fulcrum to reach the closed state. The chamfered portion 22 formed on the tip 18 is a specific structure for allowing the tip 18 to come into compact contact with the pressed portion 41. 21, the tip 19 of the second pressing portion 10 and the pressed portion 42 are also formed so as to be able to come into compact contact with each other when the cover 4 rotates about the rotation shaft 3 as a rotation fulcrum to reach the closed state. Although a chamfered portion 22 is formed on the tip 19, this chamfered portion 22 does not necessarily have to be provided.

[0036] In this embodiment, the device 1 having a cover includes a first holder 12 and a second holder 13. The first holder 12 holds a first pressing portion 8 and a first biasing member 9 inside 20. The second holder 13 holds a second pressing portion 10 and a second biasing member 11 inside 21. A first restricting portion 14 is provided on the first holder 12, and a second restricting portion 15 is provided on the second holder 13. Further, a first restricted portion 16 is provided on the first pressing portion 8, and a second restricted portion 17 is provided on the second pressing portion 10. As shown in FIG. 14, when the cover 4 is in the open state, the first restricted portion 16 comes into contact with the first restricting portion 14, thereby restricting the movement of the first pressing portion 8 in the protruding direction T. Similarly, when the cover 4 is in the open state, as shown in FIG. 16, the second restricted portion 17 comes into contact with the second restricting portion 15, thereby restricting the movement of the second pressing portion 10 in the protruding direction T.

[0037] The length L1 from the first restricted portion 16 shown in FIG. 15 to the tip 18 of the first pressing portion 8 and the length L2 from the second restricted portion 17 shown in FIG. 17 to the tip 19 of the second pressing portion 10 are the same, that is, L1 = L2. Here, the "same" in "the lengths are the same" does not require that the length L1 and the length L2 be exactly the same, and it is sufficient that both are the same within the range where the operating effects can be obtained. Furthermore, as shown in FIGS. 15 and 17, the position of the second restricting portion 15 is located downstream in the protruding direction T from the position of the first restricting portion 14. In FIG. 15, the reference sign S1 indicates the distance from the position where the first pressing portion 8 is pushed back by pressing the moving portion 5 to the first restricting portion 14. In FIG. 17, the reference sign S2 indicates the distance from the position where the second pressing portion 10 is pushed back by pressing the moving portion 5 to the second restricting portion 15. As shown in the figure, S1 < S2. That is, in this embodiment, by setting the relationship of S1 < S2, a structure is realized in which the position of the second restricting portion 15 (FIG. 17) is located downstream in the protruding direction T from the position of the first restricting portion 14 (FIG. 15). Moreover, by changing the position of the first restricting portion 14, the amount of protrusion of the first pressing portion 8 from the first holder 12 can be easily adjusted. Similarly, by changing the position of the second restricting portion 15, the amount of protrusion of the second pressing portion 10 from the second holder 13 can be easily adjusted. Note that, in this embodiment, the amount of protrusion of the second pressing portion 10 from the second holder 13 is set so that when the cover 4 is in the unlocked state, the detected member 31 rotates to a position (FIG. 4) where it is not detected by the detection portion 32.

[0038] 15 and 17 show a state in which the first pressing portion 8 and the second pressing portion 10 press the moving portion 5 to apply pressing forces P1 and P2 of the same magnitude. In other words, the first pressing portion 8 and the second pressing portion 10 are pushed back by the reaction force from the moving portion 5. By being pushed back, the first biasing member 9 and the second biasing member 11 are brought into a state in which they exert elastic forces of the same magnitude, and thus, they are configured to be able to exert pressing forces P1 and P2 of the same magnitude.

[0039] In this embodiment, the first pressing portion 8 and the second pressing portion 10 are configured from the same part. Furthermore, the first urging member 9 and the second urging member 11 are also configured from the same part. Here, "the same part" means that it includes parts that have the same structure when viewed from the front, back, top, bottom, left and right, as well as parts that are symmetrical with respect to one plane. In this embodiment, as shown in Figures 14 and 20 and Figures 15 and 21, the first pressing portion 8 and the second pressing portion 10 are the same part in the symmetrical relationship. The exact same parts are used for the first biasing member 9 and the second biasing member 11. This makes it easy to set the pressing forces P1 and P2 to be the same.

[0040] <Swing lock mechanism for moving parts> 10, the moving unit 5 is equipped with a swing lock mechanism 51. As shown in Fig. 10 and Fig. 11, in the swing lock state, the swing lock mechanism 51 is in a state in which the locking claw 52 of the moving unit 5 is locked to a locked portion 53 on the housing 2 side and does not swing. The swing lock mechanism 51 is configured such that, when the user operates the operation unit 55 in the direction of the arrow 58, the locking claw 51 swings against the spring force of the torsion coil spring 56 with the shaft 54 ​​as a fulcrum, and comes off the locked portion 53. 12 shows a state in which the swing lock mechanism 51 is released from the swing lock state. The upper part of the moving unit 5 swings around the lower part as a fulcrum, and the moving unit 5 is retracted from the position facing the recording unit 33. This makes it possible to remove the medium if it becomes clogged in the transport path in the area of ​​the recording unit 33.

[0041] 11 shows a state in which the cover 4 is open, but the swing lock mechanism 51 is in a locked state. When the cover 4 is open, the pressing forces P1 and P2 of the first pressing portion 8 and the second pressing portion 10 do not act on the moving portion 5, so that the moving portion 5 swings slightly due to its own weight and is in a position where the locking claw 52 is locked to the locked portion 53. At that time, the contact portion 57 of the moving portion 5 is slightly separated from the contacted portion 59 on the recording unit 33 side. Fig. 13 shows a state in which the cover 4 is in a closed state and the swing lock mechanism 51 is also in a locked state. In other words, from the state in Fig. 12, the moving unit 5 is pushed toward the recording unit 33 to swing the swing lock mechanism 51 to a position in which the mechanism is in a locked state, and in that state, the cover 4 is further changed from the open state to the closed state, which is the state in Fig. 13. In the state of Fig. 13, the pressing forces P1 and P2 of the first pressing unit 8 and the second pressing unit 10 act on the moving unit 5, so that the moving unit 5 further swings toward the recording unit 33 against its own weight. This swing causes the contacting portion 57 of the moving unit 5 to be pressed against the contacted portion 59 on the recording unit 33 side, bringing them into strong contact with each other. The locking claw 52 is slightly separated from the locked portion 53. This brings the moving unit 5 and the recording unit 33, which constitute the transport unit 34, to a distance sufficient for the recording unit 33 to record on the medium. In other words, the distance between the moving unit 5 and the recording unit 33 is such that the accuracy of recording on the medium can be ensured.

[0042] <Explanation of Effects of the Embodiment> (1) In this embodiment, when the cover 4 is in the open state, as shown in Figs. 14 and 16, the second pressing portion 10 protrudes from the first pressing portion 8. In other words, when the cover 4 rotates about the rotation shaft 3 as a fulcrum to change from the closed state to the open state, the second pressing portion 10 located on the tip end 7 side of the cover 4 protrudes from the first pressing portion 8 located on the base end 6 side of the cover 4. This makes it possible to ensure the opening amount of the cover 4 when opening it. At the same time, the tip of the first pressing portion 8 can be brought into contact with the cover 4 when closing the cover 4, and the first pressing portion 8 can be pressed in reliably. Furthermore, when the cover 4 is in the closed state, the pressing force P1 that presses the moving section 5 as the first pressing section 8 is biased by the first biasing member 9 and the pressing force P2 that presses the moving section 5 as the second pressing section 10 is biased by the second biasing member 11 are the same (P1=P2). As a result, when the cover 4 is closed, both sides of the moving section 5 can be pressed by the same pressing forces P1, P2 of the first pressing section 8 and the second pressing section 10. That is, the first pressing section 8 and the second pressing section 10 can evenly press two places on the moving section 5, the side closer to the rotation shaft 3 and the side farther from it.

[0043] (2) In addition, in this embodiment, the length L1 from the first restricted portion 16 provided on the first pressing portion 8 to the tip 18 of the first pressing portion 8 is the same as the length L2 from the second restricted portion 17 provided on the second pressing portion 10 to the tip 19 of the second pressing portion 10 (L1=L2). Furthermore, the position of the second restricting portion 15 provided on the second holder 13 is located downstream in the protruding direction T from the position of the first restricting portion 14 provided on the first holder 12. This makes it possible to easily achieve the above-mentioned "the pressing force P1 of the first pressing portion 8 and the pressing force P2 of the second pressing portion 10 are the same" and "when the cover 4 is in the open state, the second pressing portion 10 protrudes beyond the first pressing portion 8" with a simple structure. As a result, the same effect as above can be obtained. Moreover, by changing the position of the first restricting portion 14, the amount of protrusion of the first pressing portion 8 from the first holder 12 can be easily adjusted. Similarly, by changing the position of the second restricting portion 15, the amount of protrusion of the second pressing portion 10 from the second holder 13 can be easily adjusted.

[0044] (3) In the present embodiment, the first pressing portion 8 and the second pressing portion 10 are made of the same part, and the first biasing member 9 and the second biasing member 11 are also made of the same part. This makes it possible to standardize the parts, making manufacturing easier and reducing costs.

[0045] (4) If the device 1 having a cover has a structure using the positioning pin 23, frictional force may occur between the cover 4 and the insertion port 24 when the cover 4 is opened. However, in this embodiment, even in the case of such a structure, the cover 4 can be opened reliably. (5) In a structure in which the positioning pin 23 and the insertion opening 24 are located on the opposite side of the rotation shaft 3, the tip 7 side, i.e., the free end side, of the cover 4 tends to sag due to its own weight. In such a structure, when the positioning pin 23 is inserted into the insertion opening 24 and positioned, approximately half of the weight of the cover 4 is placed on the positioning pin 23. For this reason, friction is particularly likely to occur between the positioning pin 23 and the insertion opening 24. However, according to this embodiment, it is possible to reliably open the cover 4 even in such a structure.

[0046] (6) In addition, in this embodiment, when the lock mechanism 25 is in the unlocked state, the first pressing portion 8 and the second pressing portion 10 are biased by the first biasing member 9 and the second biasing member 11, respectively, and thus protrude. This protrusion causes the cover 4 to rotate from the closed state to the open state. As a result, when the lock mechanism 25 is in the unlocked state, the cover 4 automatically opens, improving operability for the user.

[0047] (7) In addition, in this embodiment, the amount of protrusion of the second pressing portion 10 from the second holder 13 is set so that, when the cover 4 is in the unlocked state, the detectable member 31 rotates to a position where it is not detected by the detection portion 32. As a result, when the cover 4 is in the unlocked state, the cover 4 opens against the frictional force between the positioning pin 23 and the insertion opening 24, and the open state can be detected by the detection portion 32. (8) Furthermore, in this embodiment, when the device 1 having a cover is the recording device 100, it is possible to simultaneously stabilize the distance between the recording unit 33 and the transport unit 34 when the cover 4 is in the closed state and ensure the amount of opening of the cover 4 when the cover is in the unlocked state.

[0048] Other Embodiments The device 1 with a cover according to the present invention is based on the configuration of the embodiment described above, but it is of course possible to modify or omit some of the configuration within the scope of the gist of the present invention. In the above embodiment, a recording device such as an inkjet printer has been described as the device 1 having a cover, but the device may be other than a printer. Moreover, the moving section 5 is not limited to the transport unit 34 in the embodiment, but may be, for example, a recording section having a recording head. The present invention can also be applied to a device that does not have a lock mechanism 25 or has a bar. [Explanation of symbols]
