Moreover, the number of the engaging convex part 107 and the engaging concave part 111 is not restricted to the number mentioned above, It can change suitably.

[II] Configuration and usage of cover device (see FIGS. 9 to 12)
FIG. 9 is a plan view showing the ink jet printer with the cover device closed, and FIG. 10 is a plan view showing the ink jet printer with the cover device expanded. FIG. 11: is a perspective view (a) which shows the state before attaching a cover apparatus to a main body casing, and a sectional side view (b) which shows the state after attaching. FIG. 12 is a rear view showing the ink jet printer with the cover device opened.

  Next, the configuration and usage of the cover device 14 closely related to the handle 17 will be described. When the ink jet printer 100 is not used, the cover device 14 is provided with an operation button 15B, a liquid crystal monitor 15A, and a feeding opening 15C by closing the upper opening 213 of the main casing 10 as shown in FIGS. It functions as a cover member that covers the operation panel 15. On the other hand, when the ink jet printer 100 is used, the cover device 14 is expanded upward, and the paper that supports the upper part of the paper P set on the feeding tray 20 as shown in FIGS. 1 and 10. Act as support.

  The cover device 14 is a rectangular flat plate member having a rounded corner portion, and a rotation base end connected to the main body casing 10 (specifically, the rear side corner portion of the operation panel 15 attached to the upper portion of the main body casing 10). Part) is formed with a rectangular flat plate-shaped extension flap 141 that is narrower than the entire width of the cover device 14 and has a shorter depth. In addition, a short round bar-shaped rotation shaft 142 is provided at the left and right ends of the extension flap 141. Further, the center of the front edge of the cover device 14 is cut out in a rectangular shape, and serves as a finger hooking portion 143 for hooking a finger when the cover device 14 is expanded. In addition, leg portions 144 formed by elastic members installed on the upper surface of the operation panel 15 when the cover device 14 is closed are provided at the left and right corners on the back side of the front end portion of the cover device 14. .

  The rotating shaft 142 is rotatably held by a bearing member 146 attached to the rear corner portion of the operation panel 15. The bearing member 146 includes two elastic claws 147 provided so as to face each other and a base portion 148 integrated with the elastic claws 147. Accordingly, when the rotating shaft 142 is attached to or removed from the bearing member 146, the elastic shaft 142 is pushed in or pulled out toward the gap 259 between the elastic claws 147 in a direction perpendicular to the shaft, thereby removing two elastic members. The claw 147 is elastically deformed, and the cover device 14 can be attached and detached with one touch. Further, the base portion 148 has a shape bent in a “h” shape in a side view, and the elastic claw 147 is provided in each bent portion so as to protrude inward. An end piece on the outer side of the elastic claw 147 is an angle regulating surface 149 that abuts on the upper surface or the lower surface of the extension flap 141 in the vicinity of the rotation shaft 142 of the cover device 14 and regulates the rotation angle of the cover device 14. Yes. As an example of such a cover device 14, a visual recognition window 14 </ b> A that allows the liquid crystal monitor 15 </ b> A on the operation panel 15 to be visually recognized in the closed state is opened at the center. The viewing window 14A is a rectangular opening with rounded corners, and a shielding plate 145 formed of a synthetic resin material having visibility is fitted in the opening.

  Further, the viewing window 14A is formed in a size that allows the display information 150 displayed on the liquid crystal monitor 15A to be confirmed from the outside, and is specifically formed somewhat smaller than the liquid crystal monitor 15A. The display information 150 that can be visually recognized includes current status information 151 of the ink jet printer 100 such as power ON / OFF confirmation, maintenance information 152 such as the remaining amount of ink, and setting information 153 such as paper size and paper type. Alternatively, design information 154 for displaying a still image, a moving image, or the like for the purpose of design or decoration is included. The display information 150 includes images such as characters, symbols, figures, illustrations, and photographs.

  Next, how to use the cover device 14 is as follows: (1) When the viewing window is used as a display information confirmation window, and whether or not the paper P is set is confirmed from the rear side of the ink jet printer 100. A description will be given separately when the window is used as a rear confirmation window.

(1) When the viewing window is used as a display information confirmation window (see FIG. 9)
When the viewing window 14A is used as a display information confirmation window, the cover device 14 is closed as shown in FIG. In this state, since the liquid crystal monitor 15A can be visually recognized from the visual recognition window 14A as described above, various display information 150 displayed on the liquid crystal monitor 15A can be confirmed. Based on the displayed display information 150, the power of the inkjet printer 100 is turned off, or a new spare ink cartridge is prepared.

(2) When the viewing window is used as a rear confirmation window (see FIG. 12)
When checking the presence or absence of the paper P set on the feeding tray 20 when the user is located on the rear side of the ink jet printer 100, the user can visually recognize the paper P without moving to the front side of the ink jet printer 100. The presence or absence of the paper P can be confirmed by looking into the window 14A from the rear side. That is, since the viewing window 14A is set to a size and a position where the set paper P can be confirmed, a part of the set paper P can be viewed by looking into the viewing window 14A. If the paper P does not exist, the paper P can be replenished from the rear side of the inkjet printer 100.

  The cover device 14 may adopt the following modes in addition to the modes described above. For example, the shape of the viewing window 14A provided for the cover device 14 is formed in a rectangular hole shape in accordance with the shape of the liquid crystal monitor 15A as in the above-described embodiment, and is circular, elliptical, oval, or other polygonal shape. Various shapes of holes such as holes can be employed. The number of the viewing windows 14A is not limited to one, and a plurality of viewing windows can be provided. In this case, the viewing window 14A used as the display information confirmation window and the viewing window 14A used as the rear confirmation window are selectively used. It is also possible. In addition to the display information 150 that can be confirmed from the outside through the viewing window 14A, it is also possible to play audio information, melody, and the like related to the display information 150.

[III] Other configurations and operation modes of the cover device (see FIGS. 13 to 16)
FIG. 13 is a side sectional view (a) showing a state before a certain load or more is applied to the cover device, and a side sectional view (b) showing a state after a certain load or more is applied to the cover device. FIG. 14 is a view showing another aspect of the cover device, and is a side sectional view (a) showing a state before a certain load is applied, and a side sectional view (b) showing a state after being applied. FIG. 15 is a view showing still another aspect of the cover device, and is a side cross-sectional view (a) showing a state before a certain load is applied, and a side cross-sectional view (b) showing a state after being applied. FIG. 16 is a view showing another aspect of the bearing member, and is a side cross-sectional view (a) showing a state before a certain load is applied, and a side cross-sectional view (b) showing a state after being applied.

  Next, other configurations and operation modes centering on the attachment / detachment structure of the cover device 14 included in the cover device 14 will be described. In addition, the front side used in this specification is the side where the user faces the ink jet printer 100 when using the ink jet printer 100, and the back side means the side opposite to the front side. When expressing the direction more simply, the front side may be expressed as the front side and the back side may be expressed as the rear side.

  As shown in FIG. 2, the ink jet printer 100 has a substantially rectangular parallelepiped main body casing 10, and the main body casing 10 includes a front surface 205, a back surface 207, left and right side surfaces 209 and 211, a top surface 213, and a bottom surface 215. Has been. A cover device 14 is provided on the top surface 213 of the main casing 10 so that the top surface 213 can be opened by rotating to the back surface 207 side.

  As shown in FIG. 10, the operation panel 15 provided on the top surface 213 of the main casing 10 has a power switch 227, a power indicator 228, a liquid crystal monitor 15A, and a liquid crystal monitor 15A that are examples of the operation buttons 15B. Button 231, menu selection button 233 of liquid crystal monitor 15A, paper selection button 235, paper selection display section 237, recording execution button 239, all recording execution button 241, OK button 243 for executing selection on liquid crystal monitor 15A, cancel button 245, and A discharge stacker release button 247 is provided. The operation of the discharge stacker release button 247 will be described later.

  The cover device 14 is sized to cover almost the entire top surface 213 of the main body casing 10, and the entire operation panel 15 is covered by the cover device 14 when the cover device 14 is closed. Accordingly, it is possible to prevent dust from being accumulated on the liquid crystal monitor 15 </ b> A when it is not used and from entering the gap between the operation buttons 15 </ b> B on the operation panel 15 to cause a failure. Further, the operation panel 15 can be physically protected from an impact caused when an object falls on the operation panel 15. Further, when the target model of the inkjet printer 100 is a mobile type as in the present embodiment, it is used on various places by easily moving indoors or outdoors rather than being placed on a desk or table. It is assumed that In such a case, since the entire operation panel 15 is covered with the cover device 14, it is possible to prevent the switch from being inadvertently turned ON during movement.

  Further, the rotating shaft 142 of the cover device 14 is provided on the back side of the cover device 14 as described above. The rotating shaft 142 of the cover device 14 constitutes a rotating portion of the cover device 14 in combination with the above-described bearing member 146 formed on the back surface side of the top surface 213 of the main body casing 10.

  That is, as shown in FIG. 11, the rotation shaft 142 of the cover device 14 has a constant diameter, while the bearing member 146 has a C-shaped cross section, and its receiving portion 254 has a gap portion 259 smaller than the diameter of the rotation shaft 142. The receiving holding portion 261 has an inner diameter that is substantially the same as or slightly larger than the diameter of the rotating shaft 142. When the cover device 14 is attached to the main body casing 10, the rotation shaft 142 is moved from the gap portion 259 of the bearing member 146 to the receiving holding portion 261 with the rotation shaft 142 facing the gap portion 259 of the bearing member 146. Push in the direction. As a result, the C-shaped gap portion 259 temporarily expands elastically, and both the rotating shafts 142 can enter the bearing member 146. Once the rotation shaft 142 enters the bearing member 146, the rotation shaft 142 can rotate within the bearing member 146, so that the cover device 14 can rotate with respect to the main body casing 10 about the rotation shaft 142. It becomes.

  A part of the extension flap 141 in the vicinity of the rotation shaft 142 functions as a stopper, and this extension flap 141 is a gap 259 of the bearing member 146 when the cover device 14 is rotated to the position shown in FIG. The cover device 14 is in contact with an angle regulating surface 149 formed on the upper side of the cover device 14 so that the cover device 14 does not rotate any further. When the cover device 14 is rotated to such a position, the cover device 14 is held at an angle of approximately 120 degrees with respect to the top surface 213 as shown in FIG. 1, and the back side of the cover device 14 serves as a paper support. Function. That is, when recording on a relatively long sheet P such as 4 × 6 inches, the cover device 14 functions to support the substantially upper half side of the plurality of sheets P on the back side. Incidentally, since the cover device 14 itself also functions as a paper support in this way, it is not necessary to manage the paper support as a separate member from the ink jet printer 100 as in the prior art.

  A direction in which the cover device 14 is further opened, such as when the cover device 14 is suddenly opened or when a person collides with the cover device 14 in the opened state (see FIG. 13A). When a certain load or more is applied to the inside (shown by an arrow 272) (see FIG. 13B), a part of the extension flap 141 serves as a fulcrum, and the cover device 14 further rotates in the opening direction. As a result, the rotation shaft 142 enters the gap portion 259, and the gap portion 259 is temporarily expanded beyond the receiving length 254 against the elastic force of the gap portion 259, and the rotation shaft 142 is detached from the bearing member 146. It is possible. Thereby, when there exists an above impact, it can prevent that the rotating shaft 142 or the bearing member 146 itself is damaged.

  The receiving length 254 of the gap portion 259 and the elastic modulus in the opening / closing direction of the gap portion 259 are at least a load greater than the load applied to the back surface of the cover device 14 when the maximum number of sheets P are placed on the back surface of the cover device 14. Is set so that the rotating shaft 142 can be attached to and detached from the bearing member 146.

  Further, as another aspect in which the structure for attaching and detaching the cover device 14 is different, as shown in FIG. 14, when a load of a certain level or more is applied in a direction in which the cover device 14 is further opened in the opened state, the extension is performed. When the cover device 14 further rotates in the opening direction 272 with a part of the flap 141 as a fulcrum, the receiving holding portion 261 is moved in the direction (indicated by reference numeral 274 in the drawing) of the rotation shaft 142. It may be formed to extend to the gap portion 259. By defining the positions of the receiving and holding portion 261 and the gap portion 259 in this manner, the receiving and holding portion 261 and the gap portion 259 are formed in the tangential direction when the rotation shaft 142 is about to move. Therefore, the rotation shaft 142 is more easily detached from the bearing member 146.

  FIG. 15 shows still another aspect in which the attachment / detachment structure of the cover device 14 is varied. In this aspect, another fulcrum 317 is formed behind a part of the extended flap 141 as a fulcrum. In the opened state of the cover device 14, the angle regulating surface 149 comes into contact with a part of the extension flap 141 until the cover device 14 is loaded with a certain level or more, and the opened state of the cover device 14 is maintained. On the other hand, when a certain load or more is applied to the cover device 14, the cover device 14 is further rotated slightly in the opening direction 272 so that another portion 319 of the cover device 14 abuts another fulcrum 317. Become. Then, when the cover device 14 further rotates in the opening direction 272 around another fulcrum 317, the receiving holding portion 261 is a gap portion in the direction (indicated by reference numeral 321) in which the rotation shaft 142 is about to move. It extends to 259. With such a configuration, the rotating shaft 142 is unlikely to be accidentally detached from the bearing member 146 until a load of a certain level is applied to the cover device 14, but when the load of a certain level is applied to the cover device 14, the rotating shaft 142 is Since the receiving holding part 261 and the gap part 259 are formed in the tangential direction when moving, the rotating shaft 142 is more easily detached from the bearing member 146.

  Next, another aspect in which the configuration of the bearing member 146 is varied will be described with reference to FIG. In this embodiment, the receiving and holding portion 261 and the gap portion 259 are the same as those shown in FIG. 11, but a relatively large hollow portion 278 is formed on the opposite side of the receiving and holding portion 261 from the gap portion 259, and A difference is that a bearing connecting portion 280 that is elastically deformable is formed between the hollow portion 278 and the receiving and holding portion 261. When a force component of a certain level or more toward the gap portion 259 acts on the receiving holding portion 261, the bearing connection portion 280 can be elastically deformed so that the receiving length 254 of the gap portion 259 increases.

  In such an embodiment, a constant load (f1 shown in FIG. 16 (a)) is applied to the cover device 14 in the open state of the cover device 14, but the bearing connecting portion 280 is not deformed and is shown in FIG. 16 (a). Thus, the hollow portion 278 is maintained at the height h. At this time, the receiving length 254 of the gap portion 259 is smaller than the diameter of the rotary shaft 142, so that the rotary shaft 142 cannot come out of the gap portion 259. On the other hand, when a certain load or more is applied to the cover device 14, as the cover device 14 is further rotated slightly in the opening direction 272, f1 is f2 (f2> f1) as shown in FIG. The elastically deformable bearing connecting portion 280 is slightly deformed toward the gap portion 259, and the height of the hollow portion 278 is h ′ (h ′> h). As the bearing connecting portion 280 is deformed, the receiving length 254 of the gap portion 259 increases as indicated by an arrow 323 in FIG. 16B, and as a result, the rotating shaft 142 is more easily detached from the bearing member 146. .

  In addition, returning to FIGS. 1 and 10, a projecting power-off switch 268 is provided on the top surface 213 of the main body casing 10. The power-off switch 268 turns off the power of the inkjet printer 100 when the cover device 14 is closed while the power of the inkjet printer 100 is turned on, and the part on the back side of the cover device 14 pushes the power-off switch 268. Has the function of

[IV] Configuration and operation mode of automatic opening device for discharge stacker (see FIGS. 17 to 19)
FIG. 17 is an exploded perspective view showing the automatic opening device for the discharge stacker, and FIG. 18 is a left side view (a) and a plan view (b) showing the state before the automatic opening device for the discharge stacker. FIG. 19 is a left side view (a) and a plan view (b) showing a state during the opening operation of the automatic opening device for the discharge stacker.

  Next, the configuration and operation mode of the automatic opening device 271 for the discharge stacker will be described. As shown in FIG. 2, the discharge stacker 16 is stored so as to be flush with the front face 205 of the main casing 10 when not in use. In use, as shown in FIG. 1, it can be turned to a substantially horizontal state by turning around a turning shaft 269 provided at the lower end of the front face 205. Note that a damper structure (not shown) is applied to the rotating shaft 269, and the discharge stacker 16 can be opened relatively slowly with the opening speed controlled. As shown in FIG. 1, in a state where the discharge stacker 16 is opened, a surface on which the discharge port 266 for discharging the paper P after recording and the memory insertion port 13A are formed appears.

  As shown in FIG. 17, in order to open the discharge stacker 16, the discharge stacker release button 247 is provided on the top surface 213 of the main casing 10 as a component of the automatic discharge device 271 of the discharge stacker as described above. Yes. A discharge stacker automatic opening device 271 includes a main body frame 276 including a base portion 273 and an extension portion 275, and a button that is movable in the vertical direction within the base portion 273 and has a discharge stacker release button 247 formed on the upper portion. The component member 277, a sliding member 279 incorporated in the button component member 277 and movable in the front-rear direction (front and back directions), and rotated at one end of the sliding member 279 via a rotation connecting portion 281 An opening action arm 285 that is connected freely and has an arm portion 283 formed in the other end side extending in the direction of the extension portion 275 of the main body frame 276, and a permanent magnet 287 accommodated near the tip of the extension portion 275. Be prepared.

  On both side surfaces 289 of the button constituting member 277 facing each other, slits 291 formed obliquely from the upper back side to the lower front side are formed. A coil spring 293 is fixed inside the button constituent member 277 in a compressed state in the vertical direction, and the button constituent member 277 is always urged upward by the action of the coil spring 293.

  From the lower end of the front side of the sliding member 279, a button extending member 277 and a front extension 295 extending through the base 273 of the main body frame 276 are formed, while from the rear side of the sliding member 279, the button forming member 277 and the main body are formed. A rear extension 297 extending through the base 273 of the frame 276 is formed. In addition, a bar 301 passes through both side surfaces 299 of the sliding member 279, and the bar 301 passes through two slits 291 formed on both side surfaces 289 of the button component 277. Further, the bar 301 passes through notches 305 formed on both side surfaces 303 of the base 273 of the main body frame 276. As described above, since the button component 277 is constantly biased upward by the action of the coil spring 293, the bar 301 is always in contact with the upper sides 307 of both notches 305, and the bar 301 is moved in the front-rear direction. When moving, it is guided by the upper side 307 of the notch 305.

  An opening action arm 285 is connected to the front extension part 295 of the sliding member 279 via the above-described rotation connection part 281, and the opening action arm 285 is a boundary between the base part 273 of the main body frame 276 and the extension part 275. It can be rotated around a rotation fulcrum 309 located in the vicinity. The arm portion 283 of the opening action arm 285 is curved in a substantially arcuate shape, and an opening action end 311 is formed at the tip thereof. The arm portion 283 is movable in the front-rear direction within a notch 313 formed in the extension portion 275 of the main body frame 276, and when the arm portion 283 moves to the front side (front side), the opening action end 311 is an extension portion of the main body frame 276. It protrudes greatly from the front side of H.275.

  According to the above configuration, the discharge stacker release button 247 is provided on the top surface 213 of the main body casing 10 and is covered by the cover device 14 when not in use. It is possible to prevent the stacker 16 from being opened. Further, since it is not necessary to provide a handle for opening the discharge stacker 16 in the discharge stacker 16, the discharge stacker 16 and the front face 205 of the main body casing 10 can be flush with each other when the discharge stacker 16 is closed. This makes it possible to contribute to making the entire inkjet printer 100 a clean design.

  Next, an operation mode when the discharge stacker 16 is opened by such an automatic opening device 271 of the discharge stacker will be described. A magnetic member 315 such as iron is provided on the upper portion of the discharge stacker 16, and when the discharge stacker 16 is closed, the magnetic member 315 is attracted to the permanent magnet 287 of the extension 275 so that the discharge stacker 16 is closed. Is to be maintained. When the user presses the discharge stacker release button 247 in this state, the bar 301 moves to the back side along the slit 291 and the upper side 307 of the notch 305 formed obliquely. Along with this, the sliding member 279 also moves to the back side. Then, the release action arm 285 rotates clockwise in FIG. 19, so that the release action end 311 pushes the discharge stacker 16 forward, and overcomes the attractive force between the permanent magnet 287 and the magnetic member 315, thereby discharging the stacker 16. Can be opened forward. When closing the discharge stacker 16, the user rotates the discharge stacker 16 in the vertical direction so that the magnetic member 315 and the permanent magnet 287 are attracted to maintain the closed state. Become.

  Incidentally, in order to prevent the recording from being erroneously performed when the discharge stacker 16 is closed, the operation of pushing the discharge stacker release button 247 is used as a trigger to feed the paper P and execute the recording. You may be able to do it.
