JP 2004-82455 A

  However, in a recording apparatus such as an ink jet printer, so-called ink mist is generated in which part of the ink ejected onto the recording material is mist and floats in the space inside the casing of the recording apparatus. Therefore, in a recording apparatus including a handle that is pivotally supported as described in Patent Document 1, ink mist generated inside the casing of the recording apparatus is provided in the casing of the recording apparatus. There is a possibility that the housing leaks out of the housing through a gap between the bearing hole and the rotating shaft of the handle, and ink mist adheres to the outer peripheral surface of the housing, thereby contaminating the housing.

  In this case, for example, if the fitting between the bearing hole provided in the housing and the rotation shaft of the handle is tight so that there is almost no gap between the bearing hole and the rotation shaft, the bearing hole The possibility that the ink mist leaks out of the housing through the gap between the rotating shaft and the rotating shaft can be reduced. However, if the bearing hole provided in the housing is tightly fitted to the rotating shaft of the handle, a strong frictional force acts between the bearing hole and the rotating shaft when the handle is rotated. Become. As a result, when the handle is turned, a large turning resistance is generated, the operability is lowered, and an irritating sliding sound is likely to be generated. In other words, tightening the fitting between the bearing hole provided in the housing and the rotation shaft of the handle can reduce the risk of ink mist leaking out of the housing, but may reduce the operability of the handle. The harmful effect of generating annoying sliding noise will occur.

  Further, the operability of the handle can be improved by adding a lubricant to a sliding contact engagement portion between the bearing hole and the rotating shaft, for example. However, the lubricant deteriorates due to aging, and in particular, deteriorates due to friction caused by turning of the handle and peels off. For this reason, conventionally, there has been a risk that the lubricant will be insufficient due to long-term use, and the turning resistance of the handle will increase, causing the above-mentioned adverse effects. On the other hand, for example, in order to maintain the effect of the lubricant for a long period of time, if the lubricant is excessively added to the sliding contact engagement portion between the bearing hole and the rotation shaft, the lubricant is accompanied with the rotation of the handle. May leak out of the printer casing and the outer peripheral surface of the casing may be contaminated with the lubricant.

  The present invention has been made in view of such a situation, and the problem is that in a recording apparatus in which a handle is pivotally supported in a bearing hole provided in a casing, the operability of the handle is improved. The object is to reduce the risk of ink mist adhering to the outer peripheral surface of the housing and causing the housing to become dirty without causing a drop or annoying sliding noise.

  Another object of the present invention is to add a lubricant to the sliding contact engagement portion between the bearing hole and the rotation shaft in a recording apparatus in which a handle is pivotally supported in a bearing hole provided in the housing. It is to realize the appropriate supply without shortage.

  In order to achieve the above object, according to a first aspect of the present invention, in a recording apparatus in which a handle is pivotally supported in a bearing hole provided in a housing, at least during execution of recording on a recording material. A recording apparatus comprising: a blocking device capable of blocking communication between the inside and the outside of the housing by a gap between the bearing hole and the rotation shaft of the handle.

  So-called ink mist is generated when ink is ejected from the recording head onto the recording surface of the recording material, that is, during recording on the recording material. The generated ink mist floats in the space inside the recording apparatus immediately after the occurrence, but eventually is absorbed by an ink absorber or the like inside the recording apparatus. Therefore, the ink mist floats in the space inside the casing of the recording apparatus during recording on the recording material. After recording on the recording material, the ink mist floats in the space inside the casing of the recording apparatus. Almost no ink mist is present.

  In general, during recording on a recording material, the recording device is not carried around using the handle. That is, in order to carry the recording apparatus using the handle, the user performs the turning operation of the handle in a normal usage mode, in which the recording on the recording material is not performed, particularly the recording apparatus. It is thought that it is in the state that is not used.

  In the recording apparatus according to the first aspect of the present invention, the recording apparatus between the bearing hole provided in the casing of the recording apparatus and the rotation shaft of the handle is at least during recording on the recording material by the shut-off device. Communication between the inside and outside of the housing due to the gap can be blocked. Accordingly, it is possible to reduce a possibility that ink mist generated in the casing of the recording apparatus during recording on the recording material leaks out of the casing through a gap between the bearing hole and the rotation shaft of the handle. it can.

  In addition, the recording apparatus according to the first aspect of the present invention is provided with such a blocking device, so that the fitting between the bearing hole provided in the housing and the rotation shaft of the handle is tight. The possibility that the ink mist leaks out of the housing through the gap between the bearing hole and the rotation shaft can be reduced. Therefore, it is possible to prevent a large turning resistance from occurring when the handle is turned. As a result, it is possible to prevent the operability of the handle from being deteriorated, and it is also possible to prevent an unpleasant sliding sound from being generated when the handle is operated.

  Furthermore, in the recording apparatus according to the first aspect of the present invention, when recording on the recording material is not being performed, the inside of the housing is formed by the gap between the bearing hole and the rotation shaft of the handle when the recording apparatus is not performing recording. It is possible to make a state in which the communication between the motor and the outside is not blocked, that is, a state in which the blocking device is not slidably engaged with the rotating shaft of the handle. Thereby, when recording on the recording material is not being performed, it is possible to prevent an increase in the rotational resistance of the handle due to the sliding engagement between the shut-off device and the rotational shaft of the handle. Therefore, it is possible to prevent the operability of the handle from being deteriorated in a state where recording on the recording material is not executed, that is, in a state where the user may carry the recording apparatus using the handle. In addition, it is possible to prevent an unpleasant sliding sound from being generated when the handle is operated.

  Thus, according to the recording apparatus described in the first aspect of the present invention, in the recording apparatus in which the handle is pivotally supported in the bearing hole provided in the housing, the operability of the handle is reduced. There is an effect that it is possible to reduce the possibility that ink mist adheres to the outer peripheral surface of the casing and the casing is soiled without causing annoying sliding noise.

  According to a second aspect of the present invention, in the recording apparatus according to the first aspect described above, the blocking device operates in conjunction with the rotation of the handle, and the rotation position of the handle is a predetermined rotation. In the recording apparatus, the communication between the inner side and the outer side of the housing due to the gap between the bearing hole and the rotation shaft of the handle is blocked.

  In a recording apparatus in which the handle is pivotally supported, when performing recording on the recording material, the user feeds the recording material into the recording apparatus, and discharges the recording material after execution of recording. Further, it is considered that the handle is rotated to a rotation position where the operation of the operation panel of the recording apparatus and the visual recognition of the liquid crystal display unit are not hindered. For example, when performing recording on a recording material, it is generally considered that the handle is rotated to a position hidden behind the recording apparatus.

  Therefore, depending on the configuration of the recording device, the bearing hole and the recording hole are in a state where the handle is rotated to a predetermined rotation position where the feeding and discharging of the recording material and the operation by the user are not hindered by the handle. Communication between the inside and outside of the housing by the gap between the rotation shaft of the handle is blocked. As a result, during recording on the recording material, communication between the inside and outside of the housing due to the gap between the bearing hole and the rotation shaft of the handle can be blocked.

  Further, when recording on the recording material is not executed, the operation of rotating the handle from the predetermined rotation position causes the housing to be opened by the clearance between the bearing hole and the rotation shaft of the handle by the blocking device. The state where the communication between the inside and the outside is not blocked, that is, the state where the blocking device is not slidably engaged with the rotation shaft of the handle can be achieved. Therefore, it is possible to prevent the operability of the handle from being deteriorated when recording on the recording material is not performed, and to prevent an unpleasant sliding sound from being generated when the handle is operated. can do.

  According to a third aspect of the present invention, in the recording apparatus according to the first aspect described above, the recording apparatus includes an opening / closing lid that is pivotally supported so as to be able to open and close a feeding port of the recording material. The communication between the inner side and the outer side of the housing by the gap between the bearing hole and the rotating shaft of the handle is blocked when the opening / closing lid is opened. Is a recording apparatus characterized by the above.

  The opening / closing lid that is pivotally supported so as to be able to open and close the feeding port of the recording material must be in an open state when recording on the recording material. In addition, when recording on the recording material is not performed, especially when the recording device is not used, the lid is closed to prevent dust or foreign matter from entering the recording material feeding port. It is desirable to make it.

  Therefore, in a state where the opening / closing lid is opened, communication between the inside and outside of the housing due to the gap between the bearing hole and the rotation shaft of the handle is blocked. As a result, during recording on the recording material, the inside of the housing is defined by the gap between the bearing hole and the rotating shaft of the handle without preventing the recording material from being fed through the feeding port. Communication with the outside can be blocked. Further, when the open / close lid is closed, the shut-off device does not block the communication between the inside and outside of the housing due to the gap between the bearing hole and the handle pivot shaft, that is, the shut-off device is connected to the handle pivot shaft. Can be brought into a state where they are not slidably engaged with each other. Therefore, it is possible to prevent the operability of the handle from being deteriorated when recording on the recording material is not performed, and to prevent an unpleasant sliding sound from being generated when the handle is operated. can do.

  According to a fourth aspect of the present invention, in the recording apparatus according to the first aspect described above, the recording apparatus includes a discharge tray that is pivotally supported so that a discharge port of a recording material can be opened and closed. Operates in conjunction with the opening and closing of the tray, and with the discharge tray open, the communication between the inside and outside of the housing is blocked by the gap between the bearing hole and the rotation shaft of the handle. This is a recording apparatus characterized by that.

  The discharge tray that is pivotally supported so that the discharge port of the recording material can be opened and closed must be opened when recording on the recording material. Also, when recording on the recording material is not performed, especially when the recording device is not used, the discharge tray is closed to prevent dust or foreign matter from entering the recording material discharge port. It is desirable to make it.

  Therefore, in a state where the discharge tray is opened, communication between the inside and outside of the housing due to the gap between the bearing hole and the rotation shaft of the handle is blocked. As a result, during recording on the recording material, the recording material after recording has been prevented from being discharged through the discharge port, and the housing is prevented by the gap between the bearing hole and the rotating shaft of the handle. Communication between the inside and outside can be blocked. Also, when the discharge tray is closed, the shut-off device does not block the communication between the inside and outside of the housing due to the gap between the bearing hole and the handle pivot shaft, that is, the shut-off device is rotated by the handle. The shaft can be brought into a state where it is not slidably engaged with the shaft. Therefore, it is possible to prevent the operability of the handle from being deteriorated when recording on the recording material is not performed, and to prevent an unpleasant sliding sound from being generated when the handle is operated. can do.

  According to a fifth aspect of the present invention, in the recording apparatus according to the first aspect described above, a recording head that ejects ink onto a recording surface of a recording material, an ink supply path that supplies ink to the recording head, An opening / closing valve for the ink supply path, and the shut-off device operates in conjunction with opening / closing of the opening / closing valve, with the opening / closing valve being open, between the bearing hole and the rotation shaft of the handle. The recording apparatus is characterized in that communication between the inside and outside of the housing by the gap is blocked.

  The opening / closing valve of the ink supply path for supplying ink to the recording head must be kept open when recording on the recording material. In addition, the opening / closing valve of the ink supply path causes bubbles generated in the ink supply path to flow into the ink tank or the like when recording on the recording material is not being performed, particularly when the recording apparatus is not used. In order to prevent clogging and the like, it is desirable that the closed state be provided.

  Therefore, in a state where the opening / closing valve of the ink supply path is opened, the communication between the inside and outside of the housing due to the gap between the bearing hole and the rotation shaft of the handle is blocked. As a result, during recording on the recording material, communication between the inside and outside of the housing due to the gap between the bearing hole and the rotation shaft of the handle can be blocked. When the on / off valve of the ink supply path is closed, the shutoff device does not block the communication between the inside and outside of the housing due to the gap between the bearing hole and the rotation shaft of the handle, that is, the shutoff device is It is possible to prevent the sliding shaft from slidingly engaging. Therefore, it is possible to prevent the operability of the handle from being deteriorated when recording on the recording material is not performed, and to prevent an unpleasant sliding sound from being generated when the handle is operated. can do.

  According to a sixth aspect of the present invention, in the recording apparatus according to the first aspect described above, the recording apparatus includes a driving force source that drives the blocking device, and a control device that controls the driving force source. This is a characteristic recording apparatus.

  Based on the operating state of each component of the recording device, the control device is located inside the housing due to the gap between the bearing hole and the rotating shaft of the handle at the shut-off device at least during recording on the recording material. Block communication with the outside. As a result, during recording on the recording material, communication between the inside and outside of the housing due to the gap between the bearing hole and the rotation shaft of the handle can be blocked. In addition, the control device does not block communication between the inside and outside of the housing due to the gap between the bearing hole and the rotation shaft of the handle when the recording device does not perform recording on the recording material. That is, the shut-off device is not brought into sliding contact with the rotating shaft of the handle. As a result, it is possible to prevent the operability of the handle from being deteriorated in a state where recording on the recording material is not performed, and an irritating sliding sound may be generated when the handle is operated. Can be prevented.

According to a seventh aspect of the present invention, in the recording apparatus according to the sixth aspect described above, the control device detects a recording execution operation by a user and controls the shut-off device. It is.
In this way, by detecting the recording execution operation by the user and controlling the shut-off device, at least during the execution of recording on the recording material, the housing by the gap between the bearing hole and the rotation shaft of the handle is used by the shut-off device. Communication between the inside and outside of the body can be blocked.

  According to an eighth aspect of the present invention, in the recording apparatus according to any one of the first to seventh aspects described above, the blocking device includes the gap formed between the bearing hole and the rotation shaft of the handle. In the recording apparatus, the lubricant is supplied to the rotation shaft of the handle in a state where communication between the inner side and the outer side of the housing is blocked.

  Thus, when the communication between the inner side and the outer side of the housing due to the gap between the bearing hole and the rotating shaft of the handle is blocked by the blocking device, by supplying the lubricant to the rotating shaft of the handle, The lubricant can be supplied to the rotating shaft of the handle each time recording on the recording material is executed. As a result, the lubricant can be periodically supplied to the rotating shaft of the handle, so that the lubricant can be appropriately supplied to the sliding contact engagement portion between the bearing hole and the rotating shaft. Become. As a result, the operability of the handle is reduced due to a lack of lubricant due to aging, etc., and an irritating sliding sound is generated when the handle is operated, and the lubricant leaks out of the housing due to excessive supply of the lubricant. Thus, the outer peripheral surface of the housing can be prevented from being contaminated with the lubricant.

Further, when recording on the recording paper P, the handle 20 is rotated in the direction indicated by the symbol D, and the handle 20 is rotated to the rear side of the inkjet printer 50 (FIG. 4). (B)). Accordingly, the opening / closing lid 5 can be opened, and the recording paper P can be placed on the opened opening / closing lid 5 (FIG. 2). Therefore, the automatic feeding device 70 can automatically feed the recording paper P and execute recording.

  The ink jet printer 50 includes a blocking device 30 that can block communication between the inside and the outside of the printer main body 1 (reference numeral E in FIG. 5) due to a gap between the bearing hole 9 of the printer main body 1 and the rotation shaft 21 of the handle 20. It has. The shut-off device 30 of this embodiment operates in conjunction with the rotation of the handle 20. The blocking device 30 includes a first blocking member 31, a second blocking member 41, a first rotating body 32, a second rotating body 42, a first arm portion 24, and a second arm portion 25.

  The first arm portion 24 and the second arm portion 25 are formed integrally with the rotation shaft 21 of the handle 20. Therefore, when the handle 20 pivotally supported by the bearing hole 8 is rotated by the rotation shaft 21, the first arm portion 24 and the second arm portion 25 are also rotated around the rotation shaft 21. A convex portion 241 is formed at the tip of the first arm portion 24. Similarly, a convex portion 251 is formed at the tip of the second arm portion 25.

  The first blocking member 31 and the second blocking member 41 are arranged symmetrically about the rotation shaft 21 of the handle 20 as shown in the drawing. The first blocking member 31 has a blocking portion 311, a slide portion 312, a guide groove 313 and a convex portion 314. Similarly, the second blocking member 41 includes a blocking portion 411, a slide portion 412, a guide groove 413, and a convex portion 414. The blocking portions 311 and 411 are formed in a semicircular arc shape as shown in the figure, and the inner peripheral surface shape substantially coincides with the outer peripheral surface shape of the rotating shaft 21 of the handle 20. A guide groove 313 is formed in the slide portion 312, and a guide groove 413 is formed in the slide portion 412.

  The first blocking member 31 is supported by the printer main body 1 so as to be slidable in a state where the guide groove 313 is engaged with the guide convex portion 12 formed on the inner wall surface of the printer main body 1. Similarly, the second blocking member 41 is supported by the printer main body 1 so as to be slidable in a state where the guide grooves 413 are engaged with the guide convex portions 14 formed on the inner wall surface of the printer main body 1.

  The first rotating body 32 is pivotally supported on the shaft portion 11 formed on the inner wall surface of the printer main body 1. The first rotating body 32 has a long hole 321 formed on one end side and a link hole 322 formed on the other end side. The long hole 321 is engaged with the convex portion 241 of the first arm portion 24. The projection 314 of the first blocking member 31 is engaged with the link hole 322. Similarly, the second rotating body 42 is pivotally supported by a shaft portion 13 formed on the inner wall surface of the printer main body 1. The second rotating body 42 has a long hole 421 formed on one end side and a link hole 422 formed on the other end side. The long hole 421 is engaged with the convex portion 251 of the second arm portion 25. The convex portion 414 of the second blocking member 41 is engaged with the link hole 422.

  The shut-off device 30 having such a configuration is a state in which the handle 20 is rotated to the rotation position in the standing posture (FIG. 4A), that is, the user holds the handle 20 and carries the inkjet printer 50. In such a state, the blocking portions 311 and 411 are separated from the rotation shaft 21 of the handle 20 (FIGS. 5 and 6). In this state, since the inner peripheral surfaces of the blocking portions 311 and 411 are not slidably engaged with the outer peripheral surface of the rotating shaft 21, it is possible to prevent the rotation resistance of the handle 20 from increasing.

  On the other hand, the handle 20 is rotated in the direction indicated by symbol D, and the handle 20 is rotated to the rear side of the inkjet printer 50 (FIG. 4B), that is, the user records on the recording paper P. In a state in which can be executed, the inner peripheral surfaces of the blocking portions 311 and 411 are in contact with the outer peripheral surface of the rotating shaft 21 of the handle 20 (FIGS. 7 and 8). More specifically, when the handle 20 is rotated in the direction indicated by the symbol D, the rotation shaft 21 of the handle 20 is also rotated in the direction indicated by the symbol D, and is integrally formed with the rotation shaft 21. The first arm portion 24 and the second arm portion 25 are rotated in the direction indicated by the symbol D. As a result, the first rotating body 32 and the second rotating body 42 rotate in the direction indicated by the symbol F, respectively. As a result, the first blocking member 31 and the second blocking member 41 slide in the direction indicated by symbol G, and the inner peripheral surfaces of the blocking portions 311 and 411 come into contact with the outer peripheral surface of the rotating shaft 21 of the handle 20.
