First, the upper case 11b of the web roll storage cassette 11 removed from the main body case 2 is opened with respect to the lower case 11a around a pivot 28 near the storage space 27 as shown by a two-dot chain line in FIG. Next, the web roll 20 with the left and right holder bodies 62 and 63 is placed on the left and right support portions 25 and 26 of the lower case 11a. At this time, as shown in FIG. 5, when the recording medium D2 is set so as to be pulled out from the lower peripheral surface of the web roll 20, the lower end sides of the restricting pieces 74, 75 in the left and right holder bodies 62, 63 are pulled out. The recorded medium D2 passes. Since the tip discharge portion side of the lower case 11a and the upper case 11b is largely open, the leading end of the drawn recording medium D2 is extended until it contacts the vertical piece 82a of the shutter 82. When the upper case 11b is closed with respect to the lower case 11a, the wide surface of the recording medium D2 is slightly pushed by the guide rotation shaft 76 on the lower surface of the upper case 11b. Even when the shutter 82 is separated from the vertical piece 82a, it does not largely retreat to the transport upstream side of the through hole 35 in the passage 80, and the pinch roller 23 and the driving roller 22 when set in the mounting portion as will be described later. It is not impossible to sandwich and convey the product.

  In this way, the recording medium D2 is pulled out to the tip discharge portion side of the web roll storage cassette 11, and the tip discharge portion side is guided from the insertion opening 12 in the main body case 2 to the left and right guide frames as shown in FIG. As shown in FIG. 4, when the web roll storage cassette 11 is inserted with the tip discharge portion side inclined slightly downward, the front and rear pairs projecting from the inner surfaces of both guide frames 44 and 44 are inserted. The rear guide projection 46 and the front guide projection 45 as the guide projection means sequentially enter from the front end open side of the guide groove 39. When the rear guide protrusion 46 comes into contact with the stopper portion 41 at the rear end of the guide groove 39, the upper surface of the rear guide protrusion 46 is elastically locked by the locking spring plate 42. The front guide protrusion 45 faces the position of the notch 40 at the position where the rear guide protrusion 46 is set on the stopper portion 41, and the tip discharge portion of the web roll storage cassette 11 faces the position above the drive roller 22.

The setting position (setting posture) of the storage cassette 11 is not operated by mistake. By providing the driving roller 22 in the rotation means for changing the posture of the web roll storage cassette 11, the holding and conveying operation of the recording medium D2 and the operation of changing the posture can be executed simultaneously, and the structure is also simple. The effect of becoming.

  By providing the platen 21 on the side of the web roll storage cassette 11 whose posture is to be changed, the platen 21 approaches the printing unit at the same time when the recording medium D2 is conveyed, and conversely, when the web roll storage cassette 11 is attached or detached, Since the platen 21 is separated from the printing unit, the jam processing of the recording medium D2 in the printing unit is simplified, and a separate contact / separation mechanism between the platen 21 and the printing unit is not required, and the configuration of the recording apparatus is simple. It also has the effect of becoming.

  Next, with reference to FIGS. 8 and 14, a configuration in which a single sheet 98 such as a postcard (see FIG. 16) can be selectively supplied using one web roll storage cassette 11 will be described. As shown in FIGS. 14 and 16, a supply port 90 through which the single sheet 98 can be inserted and supplied toward the lower side of the storage space 27 is formed in the rear part of the web roll storage cassette 11. On the other hand, in the conveyance space 91 between the lower case 11a and the upper case 11b and from the lower side in the storage space 27 where the web roll 20 can be stored to the opening 34 where the platen 21 is exposed, A tray 31 pivotally supported by a shaft 92 at a low position on the mouth 90 side is arranged with its urging spring 93 biased upward on its free end side. One side of the tray 31 is provided with a support portion 31a projecting sideways. On the other hand, as a biasing force restricting means, the free end side of the relay lever 94 that is rotatably fitted on the outer periphery of the inner diameter boss portion 63a in one holder body 63 for protecting the side surface of the web roll 20 is the support portion 31a. It is placed on the top surface. The pressing portion 95 projecting downward on the lower surface of the upper case 11b is a portion other than the crossing portion between the support portion 31a and the relay lever 94 (for example, a longitudinal middle portion of the relay lever 94). Only 94 is pressed downward (see FIGS. 8 and 14). Therefore, when the web roll 20 with the left and right holder bodies 62 and 63 is mounted on the support portions 25 and 26, the free end of the relay lever 94 is placed on the support portion 31a of the tray 31, and the upper case 11b is mounted. When closed, the pressing portion 95 pushes the intermediate portion of the relay lever 94 downward, the force is transmitted to the support portion 31a, and the tray 31 descends against the urging force of the urging spring 93 at its free end side. Thus, the recording medium D2 is smoothly drawn out from the web roll 20 without interference such as suppression of the lower surface of the recording medium D2 drawn out from the conveyance space 91 to the opening 34 by the tray 31.

  As shown in FIG. 15, the end of the recording medium D2 in the web roll 20 is bonded to a connecting piece 96 having a width H2 smaller than the width H1 via an adhesive or an adhesive tape. The other end is connected to the paper tube 61 via an adhesive and an adhesive tape. In this case, as shown in FIG. 15, at least one side edge 96a of the connecting piece 96 is connected such that it is located closer to the center in the width direction than the side edge D2 ′ of the recording medium D2, whereby the paper tube 61 is connected. When the recording medium D2 is rewound from the recording medium D2, the end detection sensor 77 such as a limit switch does not detect the connection piece 96 but can detect only the end of the recording medium D2. The end detection sensor 77 may be provided in the web roll storage cassette 11 or may be disposed on the recording apparatus 1 side.

Further, as shown in FIG. 16, the one side edge 90a of the supply port 90 of the web roll storage cassette 11 is disposed close to the side on which the tray 31 is disposed, and one side of the cut sheet 98 is disposed on the one side edge 90a. It supplies so that it may guide. With this configuration, when printing and recording on a single form 98 such as a postcard, the upper case 11b is once opened, and the web roll 20 is taken out from the storage space 27 together with the holder bodies 62 and 63. As a result, the relay lever 94 is also removed, so that even if the upper case 11b is closed thereafter, the pressing portion 95 does not push the tray 31 downward, and the free end side of the tray 31 is directed toward the opening 34. Energized as follows. If the cut sheet 98 is inserted from the supply port 90 in this state, the leading edge side of the cut sheet guided to the upper surface of the tray 31 is guided from the platen 21 to the passage 80. the rollers 2 3 and the driving roller 2 2, be conveyed in the X direction, because the end of the cut sheet 98 can be detected by the termination detecting sensor 77, and timing the end of the printing and recording, the drive motor of the transport driving means operating It is easy to set the end timing.

  On the other hand, when printing / recording is performed on the recording medium D2 that has been rewound from the web roll 20, the end of the winding end is detected by the narrow portion of the connecting piece 96 passing through the end detection sensor 97. This makes it easy to set the end timing of printing / recording and the end timing of operation of the drive motor of the transport driving means.

  The connecting piece 96 is omitted, the end of the recording medium D2 is cut into a narrow width, and the narrow portion is connected directly to a paper tube 61 as a core body via an adhesive or an adhesive tape. You may do it. As another embodiment of the urging force regulating means, a selection lever (not shown) is rotatably mounted on the side surface of the lower case 11a, the side surface or the upper surface of the upper case 11b, and depending on the rotation position of the selection lever, A state in which the support 31a and the like in the tray 31 are pressed to hold the tray 31 in the downward position against the force of the urging spring 93, and the free end side of the tray 31 is turned upward when it is detached from the tray 31. You may comprise so that it can select to the state to carry out.

  In the present invention, the printing unit is not limited to a thermal head, and may be an ink jet type printing head unit.
