(Example 1)
With reference to FIG. 1, the schematic configuration of the multifunction device 1 as the recording device according to the first embodiment of the present invention will be described. FIG. 1 is a schematic perspective view of the multifunction device according to the present embodiment.
In FIG. 1, the multifunction device (recording device) 1 is mainly composed of an image recording device (image recording unit) 2 and a document reading device (image reading unit) 3. The image recording device 2 has a main body portion 4 and leg portions 5 that support the main body portion 4. The document reading device 3 is arranged on the upper part of the main body 4 via the document reading device moving means 80 shown in FIG. 6 provided in the image recording device 2. An operation panel 6 is provided on the appearance portion of the main body 4 of the image recording device 2 for the user to input various settings and commands and to confirm the information of the image recording device 2 and the document reading device 3. ing.
In the XYZ coordinate system shown in FIG. 1, the X-axis and the Y-axis are in the horizontal direction and the Z-axis is in the vertical direction (the Z-axis arrow direction is the vertically upward direction) in the normally assumed installation state of the compound machine 1.
Typically, the user faces the multifunction device 1 in the direction facing the Y-axis arrow and performs various operations.

Next, a schematic configuration of the image recording device 2 will be described with reference to FIG. FIG. 2 is a schematic cross-sectional view of the image recording apparatus according to the first embodiment of the present invention.
In FIG. 2, the image recording device 2 can record an image on both roll paper and cut paper as a recording medium (recording material). When roll paper 201 is used as the recording medium,
The roll paper 201 is rotatably held by the holding portion 71 via the roll holder 7. That is, the roll paper 201 is attached to the roll holder 7 in a manner such that it is wound around the outer circumference of the roll holder 7, and both ends of the roll holder 7 are provided on both sides of the housing of the main body 4 in the X-axis direction. It is rotatably locked and held by the holding portion 71. The roll paper held by the holding portion 71 is fed by the user along the lower guide 8 to the downstream side in the paper transport path. When the tip of the roll paper 201 reaches the nip portion between the transfer roller 9 and the driven roller 10, the transfer roller 9 is rotationally driven by the transfer motor 51 shown in FIG. 5, and is sandwiched between the transfer roller 9 and the driven roller 10. Will be done.

Further, by rotationally driving the transport roller 9 in that state, the roll paper 201 is transported onto the platen 11 arranged to face the recording head 13. The platen 11 guides and supports the roll paper 201 from the back surface in the image recording unit, and guarantees a gap between the recording head 13 and the roll paper 201. A plurality of intake holes are formed in the platen 11, and are connected to a suction fan 52 as a recording medium holding force generating means via a duct 15. By driving the suction fan 52, a suction negative pressure is generated in the intake hole of the platen 11, and the roll paper 201 can be sucked and held on the platen 11. The carriage 12 is equipped with a recording head 13 which is an image recording means, and is guided and supported so as to be reciprocally movable in the ± X direction (main scanning direction) along the carriage shaft 14 as a scanning guide extending in the X direction. .. A plurality of ejection ports (nozzles) for ejecting ink are arranged in the recording head 13 in the Y direction, and while the carriage 12 is moving, these plurality of ejection ports discharge ink in the −Z direction according to the image data. Discharge. When an image for one line is recorded by the ejection operation of the recording head 13 and the movement of the carriage 12, the roll paper 201 is again conveyed by the conveying roller 9 and the driven roller 10 by a predetermined pitch in the conveying direction Y, and the carriage 12 is conveyed. Move it again and record the image of the next line.

This is repeated and the image is recorded on the entire page. The cutter 16 is provided on the downstream side of the image recording unit in the transport direction Y, and can cut the roll paper 201 to a predetermined length. The image recording operation when the cut paper is used as the recording medium is the same as that of the roll paper except that the cutting operation by the cutter 16 is not required. Further, the upper part of the recording head 13 has an openable and closable upper cover 24.

The roll cover 100 shown in FIG. 3 is attached as a cover member for the purpose of preventing dust and dirt from adhering to the roll paper 201 held in the image recording device. The roll cover 100 also serves as a tray for setting the cut paper when recording an image on the cut paper as paper. Therefore, when the roll paper 201 is attached to the image recording device 2, or when recording on the cut paper, the roll cover 100 is used in the closed state. On the other hand, when the roll paper 201 is replaced, the roll cover 100 is opened, so that the roll cover 100 is attached to the image recording device 2 so as to be openable and closable. The roll cover 100 has a curved shape so as to cover the roll paper. The side of the image recording device near the lower guide 8 has a slope shape 105, and the cut paper 203 can be set on the slope.

Roll cover arms 101 having a rotation center are attached to both the left and right sides (both sides in the X-axis direction). The roll cover 100 rotates and opens and closes by fitting the holes of the roll cover arm 101 with the rotation center shafts 72 projecting in the directions facing the X-axis directions on both sides of the main body 4 in the X-axis direction. it can. A boss 102 used for an interlocking mechanism described later projects from the roll cover arm 101 on the left side. A step portion 104 is provided on the right side of the roll cover 100, which functions as a paper guide for guiding the end portion of the paper when the cut paper is set. A paper guide 103 is attached to the slope-shaped portion. It is movable in the width direction of the paper and guides the edge of the paper opposite to the step 104. The step portion 104 and the paper guide 103 are used as a paper guide when the cut paper is set.

Next, a schematic configuration of the document reading device 3 will be described with reference to FIG. FIG. 4 is a schematic cross-sectional view of the document reader in this embodiment.
In FIG. 4, the document reading device 3 can read an image while transporting the scanned document 202. The scanned document 202 is inserted by the user into a paper feed port provided on the downstream side of the document transport direction Y1 along the document setting unit 31 that guides and supports the scanning back surface side of the scanned document 202. When the scanned document 202 is inserted into the paper feed port, the upstream document sensor 41 detects that the scanned document 202 has been inserted into the paper feed port. When the tip of the scanning document 202 reaches the nip portion of the upstream document transporting means 34 including the upstream document transport roller 32 and the upstream driven roller 33, the upstream document transport roller 32 is rotationally driven by the document transport motor 53 shown in FIG. .. As a result, the scanned document 202 is sandwiched between the upstream document transporting means 34.

A delay time is provided from the time when the upstream document sensor 41 detects the tip of the scanned document 202 until the upstream document transport roller 32 is rotationally driven. This is because the tip of the scanned document 202 is oblique to the upstream document transport roller 32 by rotationally driving the scanned document 202 with the tip abutting against the nip portion of the upstream document transporting means 34 with respect to the entire width direction of the scanned document 202. It is reduced to be set to. A suitable delay time is about 0.5 to 2 seconds, but the optimum value changes depending on the distance between the upstream document sensor 41 and the upstream document transporting means 34 in the document transport direction Y1. Further, the upstream document transfer roller 32 is rotationally driven in this state, so that the scanning document 202 is transported to the reading means 38 made of a CIS (Contact Image Sensor).

After that, the scanned document 202 is sandwiched by the downstream document transporting means 37 including the downstream document transporting roller 35 and the downstream driven roller 36, which are rotationally driven by the document transporting motor 53 in the same manner as the upstream document transporting roller 32, and the downstream documentary sensor It is conveyed until 42 detects the scanned document 202. Meanwhile, the reading means 38 detects the width information and the tilt information by executing the document reading operation of the scanning document 202 conveyed at the reading position of the reading means 38 as a pre-detection operation. When the pre-detection operation is completed, the document transport motor 53 rotates the upstream document transfer roller 32 and the downstream document transfer roller 35 in opposite directions to return the scanned document 202 and put it in the standby state.
The tip position of the scanning document 202 in the standby state is controlled so as to be downstream of the nip portion of the upstream document transporting means 34 and upstream of the scanning position of the scanning means 38 with respect to the document transporting direction Y1. ing. Then, when there is an input for starting the reading operation from the operation panel 6 or the like provided in the image recording device 2, the upstream document conveying means 34 and the downstream document conveying means 37 read while executing the document reading operation by the reading means 38. The document 202 is transported in the document transport direction Y1.

When the upstream document sensor 41 detects the rear end of the scanned document 202, the rear end position of the scanned document 202 is on the downstream side of the scanning position of the scanning means 38 with respect to the document transport direction Y1, and the nip portion of the downstream document transport means 37. It is conveyed to a position on the upstream side, and the document reading operation is completed. After that, when there is an input from the operation panel 6 or the like to start the ejection operation, the scanned document 202 is transported again, so that the scanned document 202 is released from being pinched by the downstream document transporting means 37, and the scanned document 202 is taken out. It becomes possible. Here, the scanned document 202 guided by the document ejection section 39 is ejected in a posture in which the portion on the downstream side in the transport direction is inverted in the document transport direction Y2 with respect to the portion on the upstream side. As a result, the operation of inserting the scanned document 202 into the paper feed port and the operation of taking out the scanned document 202 after the document scanning operation is completed can be performed from the same direction, so that the operability is good.
After the document reading operation is completed, the scanned document 202 is once stopped in a state of being sandwiched by the downstream document transporting means 37, but it may be conveyed until it is released from the sandwiching of the downstream document transporting means 37.

Next, the control configuration according to the present invention will be outlined with reference to FIG. FIG. 5 is a schematic block diagram showing an embodiment of the control configuration according to the present invention.
In FIG. 5, the host device 401 connected to the outside transmits an image recording command generated by the host device 401 to the main control unit 403 of the multifunction device 1. The control unit 402 mainly includes a main control unit 403, an image recording control unit 404, a document reading control unit 405, and an operation panel unit 6. The main control unit 403 includes a CPU 406, a ROM 407, and a RAM 408 that serve as calculation means. In the main control unit 403, the CPU 406 controls the entire multifunction device 1 while using the RAM 408 as a work area according to various programs and parameters stored in the ROM 407. The image recording control unit 404 is for realizing control of the transfer motor 51, the suction fan 52, the carriage motor 54, the recording head 13, the cutter 16, and the like under the instruction of the main control unit 403. The document reading control unit 405 is for realizing control of the document transport motor 53, the reading means 38, and the like under the instruction of the main control unit 403.

Next, with reference to FIGS. 6, 7 and 8, the document reading device moving means according to the present embodiment will be outlined. FIG. 6 is a schematic perspective view showing an embodiment of a document reading device moving configuration according to the present embodiment. FIG. 7 is a schematic cross-sectional view showing an example of a state in which the document reading device according to the present embodiment is located at the retracted position. FIG. 8 is a schematic cross-sectional view showing an example of a state in which the document reading device according to the present embodiment is located at an operating position.

The document reading device 3 is located above the image recording device 2, and has an operating position when the document reading operation is executed and a retracted position which is outside the roll paper operation area when the roll paper 201 of the image recording device 2 is replaced. It is possible to move to. Here, the roll paper operation area is a movement locus (exchange path) of the roll paper 201 required to set the roll paper 201 attached to the roll holder 7 on the holding portion 71, and is shown by a dotted line in FIG. Area. The roll paper 201 attached to the roll holder 7 is rolled to the holding portion 71 along the inclined guide portion 72 formed from the operating position regulating member 73 for positioning the operating position of the image recording device 2 to the holding portion 71. Alternatively, it is pulled out from the holding portion 71 and replaced. This exchange path is open so that the roll paper 201 can be exchanged when the document reading device 3 is in the retracted position and the roll cover 100 is in the open position. That is, at least when the document reading device 3 is in the operating position or the roll cover 100 is in the closed position, the exchange path is blocked by either the document reading device 3 or the roll cover 100 (roll paper). 201 cannot be replaced).

FIG. 6 shows a state in which the document reading device 3 is located at an operating position when the document reading operation is executed. The document reading device mounting members 21 are provided on both sides of the image recording device 2 in the X-axis direction, and one end of each of the rotating arm member 81 and the urging member (for example, a spring) 82 is provided. It has rotating portions (rotating shafts 281, 282) that are individually rotatably attached. The rotating arm member 81 has a rotating portion to which the other end of the urging member 82 can be rotatably attached, and an attaching portion to which the document reading device 3 is attached. The document reading device 3 is provided with connecting members 83 above both ends in the X-axis direction of the document reading device 3, and the document reading device 3 has rotating arms at both ends in the X-axis direction via the connecting members 83. It is attached to the attachment portion of the member 81.

As a result, the document reading device 3 has R1 and R1 centered on the rotating portion 281 of the rotating arm member 81 provided on the document reading device mounting member 21 from the retracted position shown in FIG. 7 to the operating position shown in FIG. , It is possible to rotate in the R2 direction. Here, the moment at which the document reading device 3 rotates in the R2 direction due to its own weight is defined as MS, and the moment at which the document reading device 3 rotates in the R1 direction due to the urging force of the urging member 82 is defined as MF. The urging force of the urging member 82 is set so that the magnitude relationship between the MS and the MF is reversed in a predetermined phase between the operating position and the retracted position in the rotation phase of the rotating arm member 81.
When the document reading device 3 is in the operating position, the document reading device 3 tries to rotate in the R2 direction because the urging force of the urging member 82 is determined so that MS> MF. However, the position of the document reading device 3 at the operating position is fixed by the rotation restricting member 84 provided on the connecting member 83 abutting against the regulating recess 22 of the operating position regulating member 73 provided on the image recording device 2. Will be done. On the other hand, when the document reading device 3 is in the retracted position, the document reading device 3 tries to rotate in the R1 direction because the urging force of the urging member 82 is determined so that MS <MF. However, when the rotating arm member 81 abuts on the retracted position regulating member 23 provided in the image recording device 2, the position of the document reading device 3 at the retracted position is fixed.

Next, the interlocking mechanism between the rotation of the document reading device 3 and the rotation of the roll cover 100 will be described with reference to FIGS. 9 to 12 and 18. 9 to 12 are schematic views of the interlocking mechanism as viewed from the left side of the image recording device 2 main body. FIG. 9 is a schematic view showing a state in which the document reading device 3 is in the operating position and the roll cover 100 is in the closed position (the state in which the roll cover 100 is located in the closed position). FIG. 10 is a schematic view showing a state in which the document reading device 3 is being rotated from the operating position to the retracted position. FIG. 11 is a schematic view showing a state in which the document reading device 3 is located in the retracted position and the roll cover 100 is located in the open position. FIG. 12 is a schematic view showing the operation of the document reading device 3 from the retracted position to the operating position.
Although the interlocking mechanism is provided on one side in the X-axis direction, the same configuration may be provided symmetrically on the opposite side.

In FIG. 9, the interlocking mechanism is composed of an arm lever 501, a rotating lever 502, an open arm 505, and a closed arm 506. The rotation axes (rotation axes) of the members constituting the interlocking mechanism are arranged in parallel with each other. The arm lever 501 as a lever member is fixed to the end of the rotation center (rotation shaft 281 as the third rotation shaft) of the rotation arm member 81, and when the document reading device 3 is rotated, the arm lever 501 also becomes Rotate. The rotary lever 502 as the first movable member (rotary member) has two levers bent at approximately 90 °, and the A lever 503 and the B lever 504 have the same rotation center (rotation shaft 252 as the first rotation shaft). It is held and is composed of overlapping in the vertical direction of the paper in the figure. The A lever 503 has an arm portion (third lever portion) that can be engaged with the arm lever 501, and an arm portion (first lever portion) that can be engaged with the closed arm 506. It has an arm portion (second lever portion) that can be engaged with the open arm 505. The arms of the A lever 503 and the B lever 504 are arranged at different positions in the phase around the rotation axis. The second movable member (rotating member) or the open arm 505 as the first arm portion applies a force to move the roll cover 100 from the closed position to the open position, and has a V-shape and rotates. The arm on the lever 502 side is short, and the arm on the roll cover 100 side is long. The second movable member or the closed arm 506 as the second arm portion applies a force to move the roll cover 100 from the open position to the closed position, has an L shape, and is on the rotating lever 502 side. The arm is short, and the arm on the roll cover 100 side is long. The open arm 505 and the closed arm 506 have the same rotation center (rotation axis 256 as the second rotation axis), and are configured to overlap each other in the direction perpendicular to the paper surface in the drawing. The rotation lever 502, the open arm 505, and the shafts 252 and 256 that serve as the rotation centers of the close arm 506 are attached to the document reading device mounting member 21 that supports the document reading device 3, respectively.

The A lever 503 and the B lever 504 of the rotation lever 502 have an integral configuration that does not rotate relative to each other, and rotate integrally while maintaining their relative phase relationships. The open arm 505 and the closed arm 506 have the same rotation center, but are configured to be independently rotatable.

FIG. 18 (a) is a perspective view of the configuration around the interlocking mechanism, which clearly shows the positional relationship of each member constituting the interlocking mechanism in the direction of the rotation axis, and FIG. 18 (b) is a perspective view of FIG. 18 (a). The figure is enlarged and the viewing angle is changed to an angle that makes it easy to understand the positional relationship in the axial direction. As shown in FIG. 18, the positional relationship of each component of the interlocking mechanism in the rotation axis direction is such that the arm lever 501, the A lever 503 of the rotation lever 502, and the close arm 506 are at substantially the same position where they overlap each other and rotate. Sometimes contact engagement is possible. Further, the B lever 504 and the open arm 505 of the rotary lever 502 are at substantially the same position where they overlap each other at a position where they do not overlap with the arm lever 501, the A lever 503, and the close arm 506, and they can be contacted and engaged during rotation. ing.

FIG. 10 shows a state in which (i) the document reading device 3 is being rotated from the operating position to the retracted position. When the document reading device 3 is rotated, the arm lever 501 also rotates, the arm lever 501 hits the A lever 503 of the rotating lever 502, and the rotating lever 502 is moved in the counterclockwise direction (first direction) in the drawing. Rotate. When the rotation lever 502 is rotated by the force received from the arm lever 501, the B lever 504 comes into contact with the shorter arm of the open arm 505 and rotates the open arm 505. The open arm 505 pushes the boss 102 as a protrusion protruding from the end of the roll cover arm 101 to open the roll cover 100.

As shown in FIG. 11, when the document reading device 3 is set to the retracted position in which the document reading device 3 is completely rotated, the rotating lever 502 returns to the original position by its own weight. That is, the rotation lever 502 has the rotation phase shown in FIGS. 9 and 11 in a state where the rotation lever 502 does not come into contact with the arm lever 501, the open arm 505, the close arm 506, or the like and no external rotational force is applied. It is designed to be balanced and stationary at the home position (origin position). An urging member such as a spring may be attached so as to return to the rotation phase (home position) shown in FIGS. 9 and 11 when the external force is released.

Further, the arm lever 501 is not always in contact (engagement) with the rotary lever 502 during movement between the operating position and the retracted position of the document reading device 3. That is, the rotary lever 502 is disengaged from the arm lever 501 from the operating position to a position close to the retracted position by a predetermined distance, and from the retracted position to a position close to the operating position by a predetermined distance. .. Therefore, the rotary lever 502, which has been disengaged from the arm lever 501, is once in the rotation direction due to the reaction force received from the open arm 505 and the closed arm 506, which are engaged with the rotary lever 502, and the action of its own weight. It will be in a state where it does not come into contact with the members of. Then, after that, it returns to the home position described above.

On the other hand, the open arm 505 is maintained in the open rotation phase of the roll cover 100 even if the rotation lever 502 returns to the home position and the contact with the B lever 504 is released, unless another external force is applied. ..

FIG. 12 shows an operation of (ii) rotating the document reading device 3 from the retracted position to the operating position. When the document reading device 3 is rotated, the arm lever 501 rotates together and comes into contact with the A lever 503, so that the rotating lever 502 rotates in the clockwise direction (second direction) in the drawing. One end side of the L-shape of the A lever 503 is pushed by the arm lever 501, and the other end side of the A lever 503 hits the close arm 506 to rotate the close arm 506. When the close arm 506 is pushed by the A lever 503 and rotates, the boss 102 is pushed to rotate the roll cover 100 in the closing direction. The direction in which the boss 102 is pushed (engaged) by the closed arm 506 is opposite to the direction in which the boss 102 is pushed by the open arm 505. When the document reading device 3 is further rotated to reach the operating position, the rotating lever 502 and the close arm 506 return to their original positions (state in FIG. 9) under their own weight. That is, when the closed arm 506 does not come into contact with the A levers 503 and 102 and no external rotational force is applied, the closed arm 506 is balanced and stationary in the rotational phase (home position) shown in FIGS. 9 to 11. Designed to do. The close arm 506 pushes the boss 102 by being pushed by the A lever 503 to rotate 100 in the closing direction. When the roll cover 100 reaches the closed position, the rotary lever 502 is disengaged from the A lever 503 and the arm lever 501 (the state in which the A lever 503 is pushed by the arm lever 501), and the above-mentioned home position is released. At the same time, the closing arm 506 is also disengaged from the A lever 503 (the state of being pushed by the A lever 503), and the rotation operation of returning to the home position described above is started. As a result, the position finally returns to the position shown in FIG.
As with the rotating lever 502, the return of the closed arm 506 to the home position may be realized by applying an external force such as an urging member instead of its own weight.

In this way, the roll cover 100 also rotates in conjunction with the rotation of the document reading device 3 by the user operation, so that it is not necessary for the user to bother to open the document reading device and then open the roll cover. The turn when replacing the roll paper can be reduced.

FIG. 13 shows an operation of closing the roll cover 100 while the document reading device 3 is in the retracted position. When the roll cover 100 is closed (broken line → solid line), the boss 102 pushes the open arm 505, and the open arm 505 rotates. At this time, the shorter arm of the open arm 505 and the A lever 503 are not on the same surface in the vertical direction of the paper surface in the drawing (the positions in the rotation axis direction are displaced and do not contact each other), so that they are in contact with the A lever 503. No (see FIG. 18). Further, the B lever 504, which is on the same surface in the vertical direction of the paper in the drawing (the positions in the rotation axis direction overlap), does not come into contact with the open arm 505 when the rotation lever 502 is in the home position. It is retracted to (rotational phase). Therefore, the rotation lever 502 does not rotate even if the open arm 505 rotates. Therefore, only the roll cover 100 can be closed without rotating the document reading device 3. Similarly, when the roll cover 100 is opened while the document reading device 3 is in the retracted position, the open arm 505 rotates together with the roll cover 100 by its own weight, but does not come into contact with the A lever 503 and the B lever 504. The rotary lever 502 does not rotate because it does not come into contact with the lever 502. Therefore, only the roll cover 100 can be opened without the document reading device 3 rotating. This is the same even when the document reading device 3 is in the operating position. When the roll cover 100 is rotated, both the open arm 505 and the closing arm 506 rotate, but they do not come into contact with the rotating lever 502, so that the document reading device The drive is not transmitted to 3. That is, when the roll cover 100 is operated regardless of the position of the document reading device 3, only the roll cover 100 can be independently opened and closed without interlocking with the document reading device 3. With this configuration, although the exchange path is blocked by the document reading device 3, the attached roll paper 102 is exposed and the state can be confirmed. This makes it possible to perform necessary maintenance such as jam processing that can be performed without moving the document reading device 3.

When the document reading device 3 is rotated from the retracted position to the operating position while the roll cover 100 is closed at the document reading device 3 shown in FIG. 13, the arm lever 501 comes into contact with the A lever 503 and rotates. The moving lever 502 rotates. The opposite end of the A lever 503 hits the close arm 506, and the close arm 506 rotates. At this time, since the roll cover 100 is closed, the close arm 506 only rotates. When the document reading device 3 comes to the operating position, the rotating lever 502 and the closing arm 506 return to their original positions by their own weight. In this way, even when the document reading device 3 is rotated from the retracted position to the operating position while the roll cover 100 is closed, the document reading device 3 can rotate without a load.

Further, as shown in FIG. 14, when the document reading device 3 is rotated from the operating position to the retracted position while the roll cover 100 is open at the operating position, the arm lever 501 is also used.
Touches the A lever 503, and the rotary lever 502 rotates. Here, since the roll cover 100 is already open and the open arm 505 is also at the position shown in FIG. 14, it does not come into contact with the rotating lever 502. In this way, even when the document reading device 3 is rotated from the operating position to the retracted position with the roll cover 100 open, the document reading device 3 can rotate without a load.

As described above, in this embodiment, the interlocking mechanism between the document reading device and the roll cover is realized by the arm lever 501, the rotating lever 502, the open arm 505, and the closed arm 506. When the document reading device 3 is rotated from the operating position to the retracted position, the roll cover 100 is interlocked and opened, and the roll paper 201 is in a state where it can be replaced. When the document reading device 3 is rotated from the retracted position to the operating position, the roll cover 100 is interlocked and closed. In this way, since the roll cover 100 opens and closes in conjunction with the rotation operation of the document reading device 3, it is possible to reduce the number of turns when replacing the roll paper. Further, the roll cover 100 can be opened and closed independently regardless of the position of the document reading device 3, and the document reading device 3 can also be rotated regardless of the position of the roll cover 100.

(Example 2)
Next, a second mode of the interlocking mechanism between the rotation of the document reading device 3 and the rotation of the roll cover 100 will be described with reference to FIG. FIG. 15 is a schematic view of the interlocking mechanism according to the second embodiment as viewed from the left side of the image recording device 2. In the configuration of the second embodiment, the same configurations as those of the first embodiment are designated by the same reference numerals as those of the first embodiment, and the description thereof will be omitted again. Matters not particularly described here in the second embodiment are the same as those in the first embodiment.

FIG. 15A shows a state in which the document reading device 3 is in the operating position and the roll cover 100 is closed. The interlocking mechanism is composed of a gear 601, a pinion gear 602, and a roll cover arm gear 610. The gear 601 corresponds to the gear provided in the image reading unit in the present invention, and is fixed to the end of the rotation center of the rotating arm member 81. When the document reading device 3 is rotated, the gear 601 also rotates. To do. As shown in FIG. 16, the pinion gear 602 has a configuration in which the A gear 603 (first gear) and the B gear 604 (second gear) are connected by a torque limiter 605, and the shaft 262 of the pinion gear 602 is a document. It is attached to the document reading device mounting member 21 that supports the reading device 3. Note that FIG. 16 is a schematic view of the pinion gear 602 viewed from a direction orthogonal to the axis 262. The roll cover arm gear 610 as the second movable member is fixed to the roll cover arm 101 attached to the end of the roll cover 100, and like the roll cover arm 101, the rotation center axis of the main body 4 It has a shaft hole into which the 72 fits. Therefore, the roll cover 100 rotates in conjunction with the rotation of the roll cover arm gear 610.

FIG. 15B shows a state in which the document reading device 3 is being rotated from the operating position to the retracted position. When the document reading device 3 is rotated, the gear 601 also rotates, and when the document reading device 3 is rotated to a predetermined angle, the gear 601 meshes with the A gear 603 constituting the pinion gear 602. The rotation of the A gear 603 is transmitted to the B gear 604 via the torque limiter 605. When the B gear 604 rotates, the meshing roll cover arm gear 610 rotates, and the roll cover 100 also rotates in conjunction with the rotation. As shown in FIG. 15C, when the document reading device 3 is set to the retracted position in which the document reading device 3 is completely rotated, the gear 601 rotates to a position where it does not mesh with the pinion gear 602.
When the document reading device 3 is rotated from the retracted position to the operating position, the gear 601 meshes with the pinion gear 602 when the document reading device 3 is rotated to a predetermined angle. When the document reading device 3 is rotated as it is, the pinion gear 602 rotates the roll cover arm gear 610. In this way, the roll cover 100 closes in conjunction with the operation of rotating the document reading device 3 to the operating position.

FIG. 17 shows an operation of closing the roll cover 100 while the document reading device 3 is in the retracted position. As described above, when the document reading device 3 is completely rotated to the retracted position, the gear 601 rotates to a position where it does not mesh with the pinion gear 602. When the roll cover 100 is rotated in this state, the roll cover arm gear 610 rotates the pinion gear 602, but the pinion gear 602 does not mesh with the gear 601 so that the document reading device 3 does not rotate. Therefore, the roll cover 100 can be closed independently. Similarly, when the roll cover 100 is opened with the document reading device 3 in the retracted position, the roll cover 100 can be opened independently because the pinion gear 602 does not mesh with the gear 601. Further, even when the document reading device 3 is in the operating position, the pinion gear 602 does not mesh with the gear 601. Therefore, even if the roll cover 100 is opened and closed, the document reading device 3 does not interlock, so that the roll cover 100 is independent. Can be opened and closed with.

When the document reading device 3 is rotated from the retracted position to the operating position with the roll cover 100 closed as shown in FIG. 17, when the document reading device 3 rotates to a specified angle, the gear 601 is set to the pinion gear 602. Engage with. The pinion gear 602 rotates and tries to rotate the roll cover arm gear 610 in the closing direction, but since the roll cover 100 is already closed, the roll cover 100 does not rotate any more. When the specified torque is applied to the torque limiter 605 of the pinion gear 602, the rotation of the A gear 603 is not transmitted to the B gear 604, and the A gear 603 slips. Therefore, the document reading device 3 can be rotated to the operating position. Similarly, when the document reading device 3 is rotated from the operating position to the retracted position with the roll cover 100 open, the roll cover 100 does not rotate any more. Therefore, it is specified in the torque limiter 605 of the pinion gear 602. The above torque is applied. Therefore, since the A gear 603 idles, the document reading device 3 can be rotated to the retracted position.

Similarly, even when the document reading device 3 is rotated from the operating position to the retracted position with the roll cover 100 open, the torque limiter 605 operates, and the roll cover 100 and the roll cover arm gear 610 are excessive. It is possible to avoid applying torque.
As the torque limiter 605 described above, a torque limiter 605 having a known configuration can be used, and the details of the configuration will be omitted.

As described above, in this embodiment, the interlocking mechanism between the rotation of the document reading device 3 and the rotation of the roll cover 100 is realized by using a gear. Further, when the document reading device 3 is located at the operating position and the retracting position, the roll cover 100 can be opened and closed independently regardless of the position of the document reading device 3 by setting the gear 601 and the pinion gear 602 to be in a disengaged state. It is possible. Further, by using a torque limiter for the pinion gear 602, the image reading device 3 can be rotated without a load regardless of the open / closed state of the roll cover 100.

In this embodiment, the rotating arm member 81 and the roll cover arm 101 are assembled with the fan-shaped gear member gear 601 and the roll cover arm gear 610, respectively, but the gear portion of the fan-shaped gear member It may be configured that only the members are integrally provided on each member.

As described above, as a multifunction device (recording device) to which the present invention can be applied, a multifunction device using roll paper as a recording medium (recording material) has been described in Examples 1 and 2. However, the multifunction device to which the present invention can be applied is Not limited to this. That is, not only paper such as plain paper, glossy paper, adhesive paper, and label paper, but also vinyl, cloth, non-woven fabric, etc., or a composite machine that uses a roll sheet or a long sheet as a recording medium instead of roll paper. It is possible to apply the present invention.
