  FIG. 3 is an enlarged front view of the handle portion 35 and the fixing portion 36 of the heater unit 23. As shown in FIG. 3, the handle portion 35 is integrally formed with a rotating shaft portion 37 at both left and right end portions thereof, and is rotated around the upper surface 32 a of the unit main body 32 of the heater unit 23 via the rotating shaft portion 37. It is provided freely. Accordingly, the posture position of the handle portion 35 is changed by rotating about 90 degrees around the rotation shaft portion 37. The posture position where the handle portion 35 stands up in a direction (upward in each drawing) intersecting the upper surface 32a of the unit main body 32 (the state shown in FIG. 2) is set as the first posture position, while the upper surface 32a. The posture position that is in a laid-down state along is taken as the second posture position.

  A cylindrical cam 38 that rotates integrally with the rotation shaft portion 37 is provided on the outer periphery of the rotation shaft portion 37. More specifically, the cylindrical cam 38 is a cylindrical rib cam for converting a rotational motion into a linear motion using the rib 38a. The rib 38a meshes with a pair of left and right cam receiving portions 39a formed at the end on the handle portion 35 side of the slide member 39 that slides on the upper surface 32a of the unit main body 32 in the left-right direction. The rib 38a of the cylindrical cam 38 is formed so as to surround the rotating shaft portion 37 while being twisted in the rotating direction. Therefore, depending on the posture position state of the handle portion 35, the cam in the left-right direction that becomes the sliding direction of the slide member 39 is formed. The meshing position of the receiving portion 39a is different. Furthermore, a fixing pin 40 extending along the left-right direction as the sliding direction of the slide member 39 is fixed by a screw 41 at the end of the slide member 39 opposite to the side on which the cam receiving portion 39a is provided. . Then, the displacement of the posture position in the handle portion 35 is transmitted to the fixed pin 40 via the rotation shaft portion 37, the cylindrical cam 38, the cam receiving portion 39 a and the slide member 39. That is, the fixed portion 36 is constituted by the cylindrical cam 38, the slide member 39 provided with the cam receiving portion 39a, the fixing pin 40, and the screw 41. Among these, the cylindrical cam 38 is fixed to the unit main body 32 of the heater unit 23 so as to be rotatable as described above. On the other hand, the slide member 39 provided with the cam receiving portion 39 a and the fixing pin 40 are fixed to the unit main body 32 of the heater unit 23 so as to be movable in the axial direction of the rotating shaft portion 37.

  As shown in FIG. 3A, when the handle portion 35 is in the first posture position, a cam and a part of the rib 38a attached to the inner position in the axial direction of the rotating shaft portion 37. The receiving part 39a meshes. Here, the axial direction of the rotating shaft portion 37 is the same as the longitudinal direction (left-right direction) of the heater unit 23. On the other hand, as shown in FIG. 3B, when the handle portion 35 is in the second posture position, a part of the rib 38a attached to the outer position in the axial direction of the rotation shaft portion 37 and The cam receiving portion 39a meshes. Therefore, when the handle portion 35 is displaced from the first posture position to the second posture position, the cam receiving portion 39a meshed with a part of the rib 38a attached to the inner position in the axial direction In order to mesh with a part of the rib 38a attached to the outer position, the slide member 39 provided with the cam receiving portion 39a moves outward from the inner side on the handle portion 35 side in the axial direction. Accordingly, the fixing pin 40 fixed to the slide member 39 also moves outward in the axial direction. As a result, the tip of the fixing pin 40 is inserted into the fixing hole 27a of the fixing plate 27 provided in the mounting portion P of the main body case 12, so that the heater unit 23 is fixed by the fixing portion 36 in the mounting portion P. It has become so.

  On the other hand, when the handle portion 35 is changed from the second posture position to the first posture position, the slide member 39 provided with the cam receiving portion 39a meshing with the rib 38a of the cylindrical cam 38 is moved to the rotation shaft portion 37. It moves toward the inner side on the handle 35 side in the axial direction. Accordingly, the fixing pin 40 fixed to the slide member 39 also moves inward in the axial direction. As a result, the tip of the fixing pin 40 is removed from the fixing hole 27a of the fixing plate 27 provided in the mounting portion P of the main body case 12, and the heater unit 23 is released from the fixed state by the fixing portion 36 in the mounting portion P. (That is, it is in a non-fixed state).

  As shown in FIGS. 3 and 4, a projecting portion 37 a as a projecting member projecting in a direction intersecting the axial direction of the rotating shaft portion 37 is provided on the outer periphery of the rotating shaft portion 37 in the handle portion 35. It has been. The tip of the protrusion 37a is formed in a square shape.

  Furthermore, one end of the heater unit 23 is coupled to the upper surface 32a and the other end is the projecting portion of the handle portion 35 at the position corresponding to the projecting portion 37a of the handle portion 35 in the left-right direction. A leaf spring 42 is provided which can be brought into contact with 37a. The leaf spring 42 is mainly composed of a straight side portion 42a erected upward from the upper surface 32a of the heater unit 23, and an oblique side portion 42b formed to bend from the upper end of the straight side portion 42a downward to the rear side. Yes. That is, the other end of the leaf spring 42 is a free end formed by the oblique side portion 42b. The oblique side 42b abuts on the protrusion 37a of the handle 35, and the handle 35 is urged to rotate in an elastic contact with the protrusion 37a. The leaf spring 42 is arranged such that a part of the oblique side portion 42b is closer to the rotation shaft portion 37 than the locus drawn when the tip of the protruding portion 37a is rotated, and the handle portion 35 is rotated. The protrusion 37a slides on the oblique side 42b of the leaf spring 42 with the displacement. At this time, the plate at the intermediate position where the position of the handle portion 35 is intermediate between the first position and the second position (position where the heater unit 23 is about 45 degrees with respect to the upper surface 32a of the unit body 32). The pressing force based on the biasing force of the spring 42 against the protruding portion 37a is the highest.

  Then, a first posture position (a state shown in FIG. 4A) sandwiching the intermediate position by reversing the biasing force by the plate spring 42 with the handle portion 35 and the leaf spring 42 as a boundary at the intermediate position of the handle portion 35. ) Or the second posture position (the state shown in FIG. 4B), a toggle mechanism that presses and urges the handle portion 35 is configured. That is, when the handle portion 35 is located at the first posture position, the handle portion 35 is biased and held counterclockwise in FIG. 4A by the leaf spring 42. Then, the handle portion 35 is rotated clockwise from the first posture position, and when the intermediate position shown in FIG. Biased in the direction. When the handle portion 35 is positioned at the second posture position, the handle portion 35 is biased and held in the clockwise direction in FIG. Therefore, the handle portion 35 is suppressed from being displaced from the first posture position to the second posture position by its own weight, and is attached to one of the first posture position and the second posture position. It is supposed to be held. In this respect, the projecting portion 37a and the leaf spring 42 function as a biasing unit that biases and holds the handle portion 35 as a handle member at the first posture position and the second posture position.

Next, the operation of the recording apparatus 11 configured as described above will be described, particularly focusing on the relationship between the handle portion 35 of the heater unit 23 and the lid body 26 of the main body case 12.
For example, when a paper jam or the like occurs in the conveyance path of the recording apparatus 11, the user places the lid 26 provided on the upper surface 12a of the main body case 12 in the non-covering position to confirm the conveyance path in the main body case 12. The opening 25 is opened by displacing. Then, after the handle unit 35 of the heater unit 23 located at the second posture position is rotated to the first posture position to release the fixed state of the heater unit 23, the handle unit 35 is gripped. The heater unit 23 is taken out of the main body case 12 by lifting it up. Then, the user confirms the conveyance path from the mounting portion P from which the heater unit 23 has been removed, and performs maintenance such as removing the jammed paper as necessary.

  When the confirmation or maintenance of the transport path is completed, the user again grips the handle portion 35 of the heater unit 23 and mounts the removed heater unit 23 in the main body case 12. Then, the heater unit 23 is fixed in the main body case 12 by rotating the handle portion 35 located at the first posture position to the second posture position. At this time, when the heater unit 23 is accurately mounted in the mounting portion P, the fixing pin 40 of the heater unit 23 is inserted into the fixing hole 27a of the fixing plate 27 in the mounting portion P. The handle portion 35 can be rotationally displaced from the first posture position to the second posture position. Therefore, as shown in FIG. 5A, when the lid body 26 is returned to the cover lid position, the handle portion 35 in the second posture position is in a non-contact state separated from the lid body 26 of the main body case 12. Therefore, since the handle portion 35 in the second posture position does not come into contact with the indented portion 26c of the lid body 26, the opening portion 25 can be properly closed by the lid body 26.

  On the other hand, when the heater unit 23 is not accurately attached to the attachment portion P, the tip of the fixing pin 40 of the heater unit 23 abuts the fixing plate 27 without being inserted into the fixing hole 27a of the fixing plate 27. The portion 35 cannot be rotationally displaced from the first posture position to the second posture position. Therefore, as shown in FIG. 5B, when the lid 26 is returned to the cover position, the cover state is regulated by the handle portion 35 in the first posture position. That is, since the upper end of the handle portion 35 in the first posture position contacts the indented portion 26c of the lid body 26 from the inside of the opening portion 25, the opening portion 25 is opened without being closed by the lid body 26.

According to the above embodiment, the following effects can be obtained.
(1) When the heater unit 23 is fixed with respect to the main body case 12, the handle portion 35 is in the second lying down position and is not in contact with the lid body 26. The lid body 26 can be closed. On the other hand, when the heater unit 23 unit is not fixed with respect to the main body case 12, the handle portion 35 is in the first posture position in which the handle portion 35 stands up and the lid body 26 is contacted from the inside of the opening portion 25. Since it will be in the contact | abutting position state, the cover body 26 cannot be closed. Therefore, the user can easily recognize the state in which the heater unit 23 is not accurately attached to the attachment portion of the main body case 12 or is not fixed by the fixing portion 36.

  (2) Since the handle portion 35 suppresses the displacement of the posture position due to its own weight and is held at one of the first posture position and the second posture position by the protruding portion 37a and the leaf spring 42, The user can easily recognize the state where the heater unit 23 is not accurately attached to the main body case 12 or is not fixed by the fixing means.

  (3) Since the hot air outlet in the unit main body 32 is provided on a surface different from the upper surface 32 a of the unit main body 32 provided with the handle portion 35, the handle portion 35 is provided inside the unit main body 32. It is possible to prevent the heater 33 from becoming hot.

In addition, you may change the said embodiment as follows.

The recording medium is not limited to the continuous paper S but may be a continuous film or the like. Further, the continuous paper S may be cut into a predetermined length during the conveyance.
-The indentation part 26c which protrudes in the inner side of the main body case 12 in the lid body 26 may have a different shape such as a substantially rectangular shape. Further, the lid 26 may not be provided with the indented portion 26 c that protrudes inside the main body case 12. In this case, it is desirable to arrange the heater unit 23 so that the upper end of the handle portion 35 located at the first posture position is located above the upper surface 12a of the main body case 12.

  -You may provide the detection means which detects the cover state with respect to the opening part 25 of the cover body 26 in the opening part 25 or the cover body 26 of the main body case 12. FIG. And if comprised in this way, since the cover state of the cover body 26 can be detected correctly by a detection means, a user is not correctly mounted | worn with the heater unit 23 with respect to the main body case 12, or by the fixing | fixed part 36 An unfixed state can be recognized more easily and accurately.

A torsion coil spring or a coil spring may be used as the biasing means instead of the leaf spring 42. Further, the heater unit 23 may not be provided with an urging means.
The device unit is not limited to the heater unit 23, and may be a different member as long as it can be attached to and detached from the main body case 12, such as an ink cartridge.

The attachment / detachment device is not limited to the recording device 11 and may be a different device as long as the device unit can be attached / detached to / from the attachment portion in the main body case.
