Monitors and printers are used while individually connected to hosts, for example, computers. Monitors are generally used on desks.
To secure accessibility, desktop printers may be put on desks and used. General desktop printers have footprints that are greater than the maximum printable size of paper. Therefore, since general desktop printers occupy large spaces on desks, it is not easy to put general desktop printers on desks. Since a large desk is needed to put both a desktop printer and a monitor on a desk, it may not be easy to efficiently use a given space for home or small office/home office (SOHO). Although a desktop printer may be used by putting it on a separate desk near a desk on which a monitor is put, accessibility to the printer may deteriorate in this case.
The print medium P is transported from an upper portion 12 to a lower portion 13 of the main body 10. For example, a feeding slot 12-1 through which the print medium P is fed may be provided to the upper portion 12 of the main body 10. The outlet 18 through which the printing-completed print medium P is discharged may be provided to the lower portion 13 of the main body 10. Although not shown in the drawings, the outlet 18 does not necessarily have to be provided to the lower portion 13 and may be provided to a lower region of a front portion 11 of the main body 10.
The printing portion 100 of the example prints the image onto the print medium P in an electrophotographic manner. The printing portion 100 may include a developing device 110 (development cartridge) that is replaceable, an exposure device 120, a transfer unit 130, and a fuser 140. The developing device 110 includes a photosensitive drum 111 and develops an electrostatic latent image into a visual toner image by supplying a toner accommodated inside the developing device 110 to the electrostatic latent image formed on the photosensitive drum 111.
The photosensitive drum 111 is an example of a photoconductor having an electrostatic latent image formed on a surface thereof, and may include a conductive metal pipe and a photosensitive layer on an outer circumference of the conductive metal pipe. The developing device 110 may include a developing roller 112. The developing roller 112 supplies the toner inside the developing device 110 to the photosensitive drum 111. A developing bias voltage may be applied to the developing roller 112. A regulating member, which is not shown, regulates, an amount of the toner supplied by the developing roller 112 to a development region in which the photosensitive drum 111 and the developing roller 112 face each other. The developing device 110 of the example employs a one-component developing manner. The developing roller 112 may be rotated in contact with the photosensitive drum 111. The developing roller 112 may be rotated while located apart from the photosensitive drum 111 by tens to hundreds of micrometers. The developing device 110 may include a supplying roller 113 attaching the toner onto a surface of the developing roller 112. A supply bias voltage may be applied to the supplying roller 113. The developing device 110 may include an agitator (not shown). The agitator may triboelectrically charge the toner inside the developing device 110 by agitating the toner. The agitator may transport the toner toward the supplying roller 113. A charging roller 114 is an example of a charger charging the photosensitive drum 111 such that the photosensitive drum 111 has a uniform surface electric potential. A charging brush, a corona charger, or the like may be used instead of the charging roller 114. Although not shown in the drawings, the developing device 110 may include a cleaning member removing foreign substances remaining on the surface of the photosensitive drum 111 after a transfer process.
The developing device 110 is a consumable that is replaced when the toner accommodated inside the developing device 110 is exhausted. The developing device 110 may be provided in the form of a development cartridge including the components described above.
The exposure device 120 forms the electrostatic latent image on the photosensitive drum 111 by irradiating the photosensitive drum 111 with light modulated in correspondence with image information. As the exposure device 120, a laser scanning unit (LSU) using a laser diode as a light source, a light emitting diode (LED) exposure device using an LED as a light source, or the like may be used.
The transfer unit 130 transfers the toner image formed on the photosensitive drum 111 onto the print medium P. For example, the transfer unit 130 may include a transfer roller that is rotated while facing the photosensitive drum 111. A transfer bias voltage for transferring the toner image onto the print medium P is applied to the transfer roller. A corona transfer unit or a pin scorotron type transfer unit may be used instead of the transfer roller.
The fuser 140 applies heat and pressure to the toner image transferred onto the print medium P, thereby fusing the toner image on the print medium P. As an example, the fuser 140 may include a heating roller and a pressing roller, which are rotated while engaged with each other to form a fusing nip. The heating roller may be heated by a heat source.
According to the configuration described above, the exposure device 120 forms the electrostatic latent image by scanning the light modulated in correspondence with the image information onto the photosensitive drum 111. The developing device 110 forms the visual toner image on the surface of the photosensitive drum 111 by supplying the toner onto the electrostatic latent image formed on the photosensitive drum 111. The print medium P loaded in a loading portion 160 is fed, one by one, to the vertically extending printing path 19. The toner image maintained on the photosensitive drum 111 due to an electrostatic force is transferred onto the print medium P by the transfer unit 130. When the print medium P passes through the fuser 140, the toner image is fused on the print medium P by heat and pressure. The fusing-completed print medium P is discharged through the outlet 18.
Although an example of the printing portion 100 of an electrophotographic type has been described, the printing portion 100 may print the image onto the print medium P in another printing manner. For example, the printing portion 100 may print the image onto the print medium P in various printing manners such as an inkjet manner, a thermal transfer manner, and the like.
The print medium P drawn from the loading portion 160 by a pickup roller 150 is transported along the vertically extending printing path 19, and is supported by a platen 180 to maintain a predetermined gap from the inkjet cartridge 170. The inkjet cartridge 170 ejects the ink onto the print medium P, thereby printing the image. The printing-completed print medium P is discharged through the outlet 18.
Referring to
The printer 1 of the example may be useful when used together with a monitor.
Such a structure may be useful to provide a special use experience to the user. For example, in the case where there is a request to print an electronic document, when the electronic document is printed by the printer 1 and output as an actual document, a user experience, in which a preview image of the electronic document requested to be printed disappears from a screen of the monitor 2 in synchronization with the output of the actual document by the printer 1, may be provided.
Referring again to
The printer 1 may have a structure stably guiding the print medium P, which is discharged through the outlet 18, to the discharge guide 30 as the discharge guide 30 is rotated in the vertical direction.
According to this configuration, when the discharge guide 30 is rotated upward around the hinge 31, the first interfering portion 32 pushes the second interfering portion 193, and thus, the variable path member 190 is rotated upward around the hinge 192. When the discharge guide 30 is rotated downward around the hinge 31, the variable path member 190 is rotated downward around the hinge 192 due to the elastic force of the second elastic member 194 such that the second interfering portion 193 is maintained in contact with the first interfering portion 32. Therefore, even though a tilt angle of the discharge guide 30 with respect to the main body 10 is changed, the print medium P discharged through the outlet 18 may be stably guided to the discharge guide 30 along the transport path 191 provided by the variable path member 190.
The printer 1 may be rotated with respect to the stand 20 in conjunction with a change in a tilt angle of the monitor 2.
It may be optional to use the first combining structure 200. For this, the printer 1 may include a first cover 210 that is removable and covers the first combining structure 200 such that the first combining structure 200 is not exposed. The first cover 210 may be combined with the front portion 11 to cover the first combining structure 200. For example, the first cover 210 may be fixed to the front portion 11 such that the first cover 210 is combined with and thus covers the first combining structure 200. As another example, the first cover 210 may be fixed to the front portion 11 by a snap-fit structure to cover the first combining structure 200. According to this configuration, the first combining structure 200 may not be exposed outside thereof when not used, thereby improving appearance quality of the printer 1. After the first cover 210 is removed, the external device may be combined with the first combining structure 200.
In the printer 1 of the example, an interlocking member 230 is combined, as the external device, with the first combining structure 200 such that the main body 10 may be rotated with respect to the stand 20 in conjunction with the change in the tilt angle of the monitor 2 located in front of the printer 1. The interlocking member 230 may include: a bracket 231 having a structure combinable with the first combining structure 200; and at least one supporting arm protruding forward from the bracket 231 and elastically rotatable around a hinge 232 which is spaced apart from a rotation shaft 21 of the main body 10 in the vertical direction, that is, in a height direction. In the example, two supporting arms 233a and 233b are rotatably supported by the bracket 231. The two supporting arms 233a and 233b may be symmetrically located with reference to the rotation shaft 21 in the vertical direction, that is, in the height direction. A third elastic member 234 applies an elastic force to a supporting arm 233 such that the supporting arm 233 is rotated in a direction in which a leading end 233-1 of the supporting arm 233 faces forward. As an example, the third elastic member 234 may be a torsion coil spring including two arms respectively supported by the supporting arm 233 and the bracket 231. A roller 235 that is rotatable may be provided to the leading end 233-1 of the supporting arm 233. The bracket 231 may include, for example, mount holes 231-1 compliant with the VESA mount standards. By fastening screws to the screw fastening portions 201 of the first combining structure 200 through the mount holes 231-1, the bracket 231 may be combined with the first combining structure 200.
The monitor 2 may be tilted backward by a user. Then, the supporting arm 233a is pushed backward by the monitor 2, and the main body 10 is rotated backward around the rotation shaft 21 with respect to the stand 20. Here, the discharge guide 30 may be maintained in contact with the lower edge 2-1 of the monitor 2 due to the elastic force of the first elastic member 40. When the monitor 2 returns to an original state thereof, the supporting arm 233b is pushed backward by the monitor 2, and the main body 10 is rotated around the rotation shaft 21 with respect to the stand 20 and thus returns to an original state thereof. The supporting arms 233a and 233b may be maintained in contact with the rear surface 2-2 of the monitor 2 due to the elastic force of the third elastic member 234. In the case where the roller 235 that is rotatable is provided to the leading end 233-1 of each of the supporting arms 233a and 233b, since the rear surface 2-2 of the monitor 2 is in rolling contact with the roller 235, the main body 10 may be softly rotated in conjunction with the change in the tilt angle of the monitor 2.
As such, according to a structure in which the printer 1 has a tilt angle in conjunction with the tilt angle of the monitor 2, and in which the discharge guide 30 is maintained in contact with the lower edge 2-1 of the monitor 2, when the electronic document described with reference to
The external device may be the monitor 2. That is, the monitor 2 may be combined with the first combining structure 200. In this way, a monitor-integrated printer may be implemented.
In an example, the monitor 2 may be combined with the first combining structure 200 by an adaptor bracket. The adaptor bracket may include a first adaptor bracket 240, and a second adaptor bracket 250 that is combined with the monitor 2, for example, the rear surface 2-2 of the monitor 2. A first connecting portion 241 may be provided to the first adaptor bracket 240, and a second connecting portion 251 combined with the first connecting portion 241 in a male-female combining manner may be provided to the second adaptor bracket 250. The first connecting portion 241 may be detachably combined with the second connecting portion 251 in the vertical direction. As an example, the first connecting portion 241 may have a slot shape that is cut open in the vertical direction, and the second connecting portion 251 may have a clip shape that extends in the vertical direction to be insertable into the first connecting portion 241 of a slot shape in the vertical direction.
According to this configuration, since the stand 20 of the printer 1 may function as a stand 2-3 (
Since the monitor 2 is removable, the monitor 2 of various sizes may be combined with the printer 1, as needed. The discharge guide 30 may be naturally brought into contact with the lower edge 2-1 by the elastic force of the first elastic member 40 when the monitor 2 is combined with the main body 10. Therefore, when the electronic document described with reference to
In some cases, the printer 1 may be used as a stand-alone printer by removing the monitor 2 and combining the first cover 210 with the front portion 11.
The structure shown in
The stand 20 is combined with the rear portion 16 of the main body 10. The stand 20 includes the rotation shaft 21 supporting the main body 10 such that the main body 10 is rotatable in the front-rear direction. A second combining structure 260 may be provided to the rear portion 16 of the main body 10. The second combining structure 260 may include, for example, one or more screw fastening portions 261 (screw holes). The number of screw fastening portions 261 and an interval therebetween are not limited. For example, the number of screw fastening portions 261 and the interval therebetween may comply with the VESA mount standards. According to this configuration, the stand 20 satisfying the VESA mount standards may be directly combined with the second combining structure 260. In addition, the stand 20 may be combined with the second combining structure 260 via an adaptor satisfying the VESA mount standards.
It may be optional to use the second combining structure 260. For example, the stand 20 may be combined with the side portion 14 of the main body 10, as shown in
According to this configuration, since the stand 20 of the printer 1 may function as the stand 2-3 of the monitor 2, the separate stand 2-3 of the monitor 2 is not needed. When there is the stand 2-3 for the monitor 2, the printer 1 needs to be located at a position allowing no interference between the discharge guide 30 and the stand 2-3, that is, at a position biased toward one side in the width direction of the monitor 2 with respect to the stand 2-3. According to the example, since there is no interference between the print medium P output from the discharge guide 30 and the stand 2-3 of the monitor 2 due to the absence of the stand 2-3, the printer 1 may be mounted at various positions in the width direction of the monitor 2, for example, at a central position in the width direction of the monitor 2. Since the monitor 2 is removable, the monitor 2 of various sizes may be combined with the printer 1, as needed. The discharge guide 30 may be naturally brought into contact with the lower edge 2-1 by the elastic force of the first elastic member 40 when the monitor 2 is combined with the main body 10. Therefore, when the electronic document described with reference to
While examples have been described with reference to the drawings, it will be understood that these are examples, and that various changes and equivalent examples may be made therefrom without departing from the spirit and scope as defined by the following claims. Therefore, the scope of the disclosure should be defined by the accompanying claims.
