Description:
[0001]    The disclosure of Japanese Patent Application No. 2006-288138 fled on Oct. 23, 2006 including specification, drawings and claims is incorporated herein by reference in its entirety. 
       BACKGROUND 
       [0002]    The present invention relates to a media processor capable of providing desired media by writing data on media such as CDs and DVDs and by conducting printing on label faces of the media. 
         [0003]    Conventional media processors, which write data on plate-shaped media such as CDs and DVDs and conduct label-printing, are utilized by supplying blank media accommodated in a blank media stacker to a media drive incorporated into the media processor and predetermined data is written on the media. Subsequently, label-printing is conducted on the media by a label-printer. Then, the media are stored in a media stacker or are taken out from the media processor. 
         [0004]    The above media processor includes a case into which the media drive or the label-printer for conducting label-printing are incorporated so that the equipment arranged inside the media processor can be protected from vibration and dust from the outside. Examples of such a media processor are described in Non-patent Documents 1 and 2.

         [0011]    When the media processor is used, various maintenance operations must be conducted. For example, when blank media are supplied from the blank media stacker to the media drive and data is written on the blank media or printing is conducted on label-faces of the media by the label printer, it is necessary to replenish the blank media stacker with new blank media. Further, in the case where ink has been consumed for label-printing, it is necessary to replace ink cartridges with new ones. The above maintenance operations must be conducted according to the user&#39;s own frequency of using the media processor. On the other hand, it is impossible for the user to conduct the inspection for preventing processor trouble, and it is also impossible for the user to repair the processor trouble. Therefore, it is necessary to ask a professional service man to do the work. In general, such maintenance is not frequently conducted. Accordingly, the user would like to avoid the troublesome process of moving the media processor or removing the case from the media processor. Even in the case where the service man conducts the maintenance operations, it is desirable to avoid a complicated operation such as an overhaul of the entire media processor. 
       SUMMARY 
       [0012]    It is therefore an object of the described embodiments to provide a media processor where maintenance operations are easy. 
         [0013]    In order to achieve the above objects, according to an aspect of the described embodiments, there is provided a media processor comprising: a media storage adapted to store a plate-shaped medium; a media drive operable to write data in the medium; a label printer operable to print on the medium; a media conveyer operable to convey the medium between the media storage, the media drive and the label printer; a casing defining an interior space of the media processor; and a plate-shaped frame dividing the interior space into a first space located in a rear upper portion of the interior space, a second space located in a rear lower portion of the interior space and a front space located in a front portion of the interior space, wherein: the media drive is disposed in the first space; the label printer is disposed in the second space; and the media storage and the media conveyer are disposed in the front space. 
         [0014]    With the above configuration, the interior space of the media processor is divided into a plurality of spaces. Therefore, when maintenance operations are conducted on any equipment incorporated into the media processor, a space in which the equipment is disposed is opened so that the equipment can be repaired or replaced. Since maintenance operations on the media drive and the label printer should be conducted by a professional service man (professional maintenance), the media drive and the label printer are disposed at the rear of the media processor. Since maintenance operations on the media storage portion can be performed by a user (user maintenance, the media storage portion is disposed in the front of the media processor. Accordingly, user maintenance, such as replacement of the media, can be easily conducted from the front side of the processor. That is, only when less frequent professional maintenance operations are needed, maintenance may be conducted from the rear side of the processor. Therefore, the maintenance properties of the entire media processor are improved. 
         [0015]    Trouble with the media drive tends to occur in the media processor. Since the media drive is disposed in the rear upper space of the media processor, professional maintenance can be easily conducted. In this context, a part of the casing in the rear face of the processor is detached, and the rear face of the processor is opened; or a part of the casing on the rear face of the processor and a part of the casing on the upper face of the processor are detached, and a rear face and an upper face of the processor are opened. In this state, the media drive can be easily replaced. 
         [0016]    Further, since the printer which is more complicated and delicate than the media drive is disposed in another space, even when maintenance operations are conducted on the media drive, the printer is seldom affected. 
         [0017]    As described above, when maintenance operations are conducted, it is necessary to pay attention to the other device components from the viewpoint of delicacy, precision and accuracy so that the other components will not be affected. Since the media processor is divided into a plurality of spaces for corresponding components, even when maintenance operations are conducted in one of the spaces, the components disposed in the other spaces are not affected. 
         [0018]    The media processor may further comprise an ink supplier operable to supply ink to the label printer. The front space may be divided into a third space and a fourth space adjacent the third space. The media storage and the media conveyer may be disposed in the third space. The ink supplier may be disposed in the fourth space. Further, the casing may include a first door for the third space and a second door for the fourth space. 
         [0019]    With the above configuration, the ink supplier and the media storage are disposed in different spaces in the front of the media processor. Therefore, the media processor can be maintained without affecting the ink supplier by the user maintenance operations such as replacement of media. Further, since the doors are respectively provided for the third space and the fourth space, the maintenance operations can be independently conducted for each component. When the second door for the ink supplier is opened, the ink cartridge can be easily replaced. When the first door for the media storage is opened, the blank media can be easily replenished, and the finished media can be easily taken out. 
         [0020]    The media processor may further comprise a power supply unit; and a fan operable to take outside air into the interior space. The power supply unit and the fan may be disposed in the first space. 
         [0021]    With the above configuration, the media drive and the power supply unit, from which heat is generated, are disposed in the same space, and the fan takes countermeasures against the generated heat. Therefore, the processor can be effectively cooled by the fan. Further, the first space is located in an upper portion of the processor. Accordingly, since it is difficult for high temperature air to flow downward, a high cooling efficiency can be obtained. In the described embodiments, the label printer, which is disposed in the second space lower than the first space, can be seldom affected by heat. In the case of an ink jet printer in which dogging of ink tends to occur due to dryness, the above arrangement of components can provide an advantageous effect. Further, the power supply unit and the fan are disposed in the same space as the media drive, the installation space of which is smaller than that of the label printer. Therefore, the interior space of the media processor can be effectively utilized, and the entire media processor can be downsized. 
         [0022]    At least one of a rear face and an upper face of the casing may be independently removable so that the first space is opened. 
         [0023]    With the above configuration, the rear face or the upper face of the casing can be independently removed. Therefore, in the case of maintaining the media drive disposed in the rear upper portion, the first space can be opened, and the media drive can be exposed by removing at least one of the rear face and the upper face of the casing. Therefore, at the time of maintaining the media drive, the number of parts to be removed can be reduced, and the maintenance property can be enhanced. 
         [0024]    The plate-shaped frame may be formed with an opening communicating between the first space and the second space, and the opening may be closed by a cover. 
         [0025]    With the above configuration, when the label-printer, which is disposed in the space in the rear lower portion of the media processor, is maintained, it is unnecessary to remove a plate-shaped frame defining the boundary between the rear upper space and the rear lower space. By removing only the cover closing the opening communicating between the rear upper space and the rear lower space, it is possible to have access to the rear lower space from the rear upper space. 
         [0026]    In another exemplary aspect, a media processor for processing a plate-shaped medium, such processing including medium storage, data writing and label printing, comprises a casing defining an interior space of the media processor and housing media processor components for performing the processing, the interior space being divided into a first professional maintenance access portion, a second professional maintenance access portion, and a user maintenance access portion, wherein the media processor components for data writing and label printing are disposed in the first professional maintenance access portion and the second professional maintenance access portion, respectively, and wherein the media processing components for medium storage are disposed in the user maintenance access portion. The media processor may additionally include an ink supply mechanism that supplies ink to the media processor component for label printing, where the ink supply mechanism is disposed in the user access maintenance portion.

     DETAILED DESCRIPTION OF THE EMBODIMENTS 
       [0038]    Hereinafter, an embodiment of the media processor will be described in detail with reference to the drawings. 
         [0039]    First, an overall arrangement of the media processor of the present embodiment will be described. 
         [0040]    As shown in  FIGS. 1 to 4 , the media processor  1  is a media processor (disk publisher) for writing data onto media such as CDs and DVDs and for conducting printing on label-faces of the media. The media processor  1  includes a case  2 , the shape of which is a substantially rectangular parallelepiped. Opening and closing doors  3 ,  4 , which can be opened and closed to the right and left, are attached to a front side of the case  2 . In a front face upper side right end portion of the case  2 , an operation panel  5 , on which indicating lamps and operation buttons are arranged, is provided. A media discharge port  6  is provided at a lower end portion of the case  2 . The opening and closing door  3  has a transparent window portion, through which the inside of the media processor can be viewed from the outside. An upper face, both sides and a rear face of the case  2  are respectively independent from one another. Therefore, the upper face, both sides and the rear face can be individually attached to and detached from the case  2 . 
         [0041]    The opening and closing door  3  arranged on the right in the front view (on the left of the media processor) is opened and closed when blank media MA which have not been used yet, are set or when media MB which have already been finished, are taken out. 
         [0042]    The opening and closing door  4  arranged on the left in the front view (on the right of the media processor) is opened and closed when an ink cartridge  12  of the label printer  11  is replaced. When this opening and closing door  4  is opened, a cartridge attaching portion  14  (shown in  FIG. 6 ) having a plurality of cartridge holders  13  arranged in the perpendicular direction is exposed. The cartridge attaching portion  14  is a portion of an ink supply mechanism  71  for supplying ink into an ink jet head  61  (shown in  FIG. 8 ) of the label-printer  11 . 
         [0043]    As shown in  FIGS. 2(A) and 2(B) , the inside of the media processor  1  is covered with a plurality of plate-shaped frames (as also shown in  FIG. 5 ). In this case, the plurality of plate-shaped frames include a base frame  72  ( FIG. 6 ), a left side frame  2   a , a right side frame  2   b , a front top frame  2   c , a rear top frame  2   d , a back frame  2   e , a rear upper, lower partitioning frame  2   f , and a front, rear partitioning frame  2   g . The inside of the media processor  1  is roughly divided into a first division A 1  in the rear upper portion, a second division A 2  in the rear lower portion, a third division A 3  in the front right portion, and a fourth division A 4  in the front left portion. In the first division A 1  in the rear upper portion, the media drive  51  for writing data onto media is arranged. In the second division A 2  in the rear lower portion, the label printer  11  for conducting printing on the label faces of the media is arranged. In the fourth division A 4  of the front left portion, the ink supply mechanism  71  having the cartridge attaching portion  14  is arranged. In the third division A 3  of the front right portion, the media storage portions  21 ,  22  for storing the media are arranged. 
         [0044]    As shown in  FIG. 3 , inside the case  2  of the media processor  1 , a blank media storage portion  21 , which is a media stacker capable of stacking a plurality of blank media MA which have not been used yet, and a finished media storage portion  22 , which is a media stacker for storing finished media MB, are coaxially arranged in the vertical direction in the third division A 3 . 
         [0045]    The blank media storage portion  21  includes a pair of right and left arcuate frame plates  24 ,  25 . By these arcuate frame plates  24 ,  25  forming a stacker, blank media MA are received from above and stacked on one another in the axial direction. When the opening and closing door  3  is opened and the stacker is taken out, the blank media MA can be easily accommodated or supplemented to the blank media storage portion  21 . 
         [0046]    The finished media storage portion  22 , which is arranged on the lower side, is composed in the same manner as that of the blank media storage portion  21 . The finished media storage portion  22  includes a pair of right and left arcuate frame plates  27 ,  28  forming a stacker. The finished media MB are received from above and are stacked on one another in the axial direction. 
         [0047]    In the case where media are discharged into a media discharge port  6 , the finished media MB, on which data has been written and label face printing has been finished, that is accommodated in the finished media storage portion  22  can be easily taken out under the condition that the opening and closing door  3  is kept closed. 
         [0048]    In this instance, the media stacker of the finished media storage portion  22  can be used as a blank media storage portion. In this case, the finished media may be discharged into the media discharge port  6 . 
         [0049]    As described above, the media storage portions  21 ,  22  are portions on which a user conducts the maintenance operations. For example, according to a state of use of the media, the blank media MA are supplemented into the storage portions, or the finished media MB are taken out from the storage portions by the user. This maintenance can be easily conducted when the opening and closing door  3  on the front face of the media processor is opened. 
         [0050]    With reference to  FIG. 6 , a stacker  52  for the media to be discarded is arranged in a lower portion of the media delivery position of the media tray  15  of the label printer  11  (described later). The media MD to be discarded and the finished media MB are temporarily stored in the stacker  52 . The media to be discarded, for example, about 30 media MD to be discarded can be stored. Under the condition that the media tray  15  is withdrawn from the media delivery position in the upper portion of the stacker  52  for the media to be discarded to the printing position, that is, in the state shown in  FIGS. 6 and 7 , the media MD to be discarded can be supplied to the stacker  52  by a conveyance arm  36  of the media conveyance mechanism  31 .

FIGS. 6 and 7  show a state in which the media tray  15  of the label printer  11  is located at a label printing position on the inner side. On the media tray  15 , a circular low protrusion  15   a  is provided which regulates a movement of each medium when the circular protrusion comes into contact with an outer circumferential end face of the medium. 
         [0060]    As shown in  FIG. 8 , the label printer  11  includes a carriage  62  having an ink jet head  61 . The carriage  62  is supported along the carriage guide shaft  63  (shown in  FIG. 7 ) so that the carriage  62  can be reciprocated in the horizontal direction. The carriage  62  includes: a timing belt  64  horizontally provided along the carriage guide shaft  63 ; and a carriage motor  65  for driving the timing belt  64 . 
         [0061]    The ink jet head  61  mounted on the carriage  62  is arranged in such a manner that the nozzle face is directed downward. At the lower side position of the ink jet head  61 , the media tray  15  can be horizontally reciprocated in the longitudinal direction. A right end of the media tray  15  is supported by the guide shaft  66  horizontally extending in the longitudinal direction. A left end of the media tray  15  is slidably supported by the guide rail  67  horizontally extending in the longitudinal direction. The drive mechanism of the media tray  15  includes: a timing belt (not shown) horizontally provided in the longitudinal direction; and a tray motor for driving the timing belt. 
         [0062]    On the lower side at the home position (shown in  FIG. 8 ) of the carriage  62 , an ink suction mechanism  81  is provided. The ink suction mechanism  81  includes: a cap  82  for covering nozzles of the ink Jet head  61  exposed on the lower face of the carriage  62  arranged at the home position; and a waste ink suction pump  83  for sucking waste ink discharged into the cap  82  by the head cleaning operation or the ink charging operation conducted by the ink jet head  62 . 
         [0063]    Waste ink sucked by the waste ink suction pump  83  of the ink suction mechanism  81  is sent into a waste ink absorption tank  85  through a tube  84 . The waste ink absorption tank  85  includes absorbing material (not shown) arranged in the case  86 . An upper face of the waste ink absorption tank  85  is covered with a cover  88  having a plurality of holes  87 .

         [0067]    The frequency of maintenance of the label printer  11  and the media drive  51  is so low that preventative maintenance of inspection and any repair work are conducted by a professional service man; that is, in general, a user seldom conducts these maintenance operations. As described above, the label printer  11  is arranged in the second division A 2  in the rear lower portion, and the media drive  51  is arranged in the first division A 1  in the rear upper portion. Therefore, in the case where professional maintenance is conducted, the back frame  2   e  on the rear face of the media processor is removed so as to open the rear face of the media processor. Alternatively, the back frame  2   e  and the rear top frame  2   d  are removed so as to open the rear and the upper face of the media processor. In this state, the media drive  51  can be easily replaced, and access for such maintenance is improved. Concerning the label printer  11 , the frequency of professional maintenance is the highest next to the media drive  51  because waste liquid processing is required for the label printer  11 . When the back frame  2   e  on the rear face of the media processor is removed, it is possible to replace the waste liquid absorption tank  85 . 
         [0068]    In the media processor  1  described above, on the base frame  72  which is horizontally placed, the left side frame  2   a , the right side frame  2   b  and the back frame  2   e  are vertically arranged and fixed with screws or the like. On the upper faces of the frames, the front top frame  2   c  and the rear top frame  2   d  are fixed with screws or the like. The media processor  1  further includes: a partition frame  2   f  for vertically partitioning the rear portion; and a partition frame  2   g  for longitudinally partitioning the upper portion. The partition frames  2   f  and  2   g  are preferably integrally formed. The frames can be individually attached to and detached from the media processor. The upper face, both the sides and the rear side of the processor can be individually attached and detached. The opening and closing doors  3 ,  4  are attached on the front face of the media processor. 
         [0069]    Due to the above frame structure, the inside of the media processor is divided into the first division A 1  in the rear upper portion, the second division A 2  in the rear lower portion, the third division A 3  in the front right portion and the fourth division A 4  in the front left portion. In the first division A 1  in the rear upper portion, the media drive  51  for writing data on the media is arranged. In the second division A 2  in the rear lower portion, the label printer  11  for conducting printing on the label faces of the media is arranged. In the fourth division A 4  in the front left portion, the ink supply mechanism  71  having the cartridge attaching portion  14  is arranged. In the third division A 3  in the front right portion, the media storage portions  21 ,  22  for storing the media are arranged. 
         [0070]    A plate-shaped frame, which covers the division in which the equipment is arranged, can be removed, and the equipment can be repaired or replaced. Since the media drive  51  and the label printer  11 , for which professional maintenance is required, are arranged at the rear of the media processor, and since the ink supply mechanism  71  and the media storage portions  21 ,  22 , on which user maintenance is conducted, are arranged in the front of the media processor, the usual user maintenance can be easily conducted from the front side of the media processor when the opening and closing doors  3 ,  4  are opened. Only when the less frequent professional maintenance is required, are the maintenance operations conducted from the rear side of the media processor. Accordingly, the maintenance properties of the entire media processor are improved. 
         [0071]    A size in the width direction of the media drive  51 , which is provided in the first division A 1  in the rear upper portion, is smaller than that of the label printer  11 . Accordingly, the electric power supply portion  55 , the cooling fan  54  for radiating heat and the control board  56  are arranged on the side of the media drive  51 . See  FIGS. 2(A) ,  2 (B) and  4 . The media drive  51  and the electric power supply portion  55 , from which heat is generated, can thus be arranged in the same division (the first division A 1 ), and the cooling fan  54  is also arranged therein for taking countermeasures against the generated heat. Since the first division A 1  is arranged in the upper portion of the media processor and air heated at high temperature is difficult to flow downward, the cooling efficiency inside of the media processor is improved. The label printer  11  in the second division A 2 , which is arranged at a lower position than the first division A 1 , is seldom affected by heat. Since the label printer  11  is provided with the ink jet head  61  which tends to be damaged by dryness, the above equipment arrangement provides a great advantage. Further, space in the media processor  1  can be effectively utilized, and the entire media processor  1  can be downsized. 
         [0072]    An opening hole  2   fb  is provided in the partition frame  2   f , which is an opening portion. Usually, this opening hole  2   fb  is closed by a cover frame  2   fa  which is a cover member. When the ink jet head  61 , which is located in the second division A 2  in the rear lower portion, is replaced, the media drive  51  and the electric power supply portion  55 , which are located in the first division A 1  in the rear upper portion, are removed. Then, the cover frame  2   fa  is detached so that the ink jet head unit  61   a  mounted on the carriage  62  can be exposed. Subsequently, the screw  61   b  is disengaged from above. In this way, the ink jet head unit  61   a  and the ink jet head  61  mounted on the head unit  61   a  can be easily replaced. 
         [0073]    In the above embodiment, the media storage portions  21 ,  22  are arranged on the left in the front of the case  2 , and the ink supply mechanism  71  is arranged on the right side in the front portion. However, the media storage portion  20  may be arranged on the right side in the front portion, and the ink supply mechanism  71  may be arranged on the left side in the front portion. 
         [0074]    While the invention has been described in connection with what is presently considered to be the most practical and preferred embodiments, it is to be understood that the invention is not to be limited to the disclosed embodiments, but on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
