■■■ 2. Details of the paper receiving tray 8 ■■■■■■■■■■■■■■■■■■■■■■■
The above is the overall configuration of the printer 1, and the paper discharge receiving tray 8 as a medium receiving tray will be described in further detail below.
In the present embodiment, the entire area of the sheet receiving surface 8a for receiving the sheet is formed by a single member, that is, the sheet discharge receiving tray 8 is configured as a single-stage tray instead of a multistage (drawer type). More specifically, in this embodiment, the entire paper discharge receiving tray 8 is integrally formed of a resin material. As a result, the overall rigidity of the paper discharge receiving tray is improved, and the cost is reduced by simplifying the structure.

  The discharge receiving tray 8 has an end portion (an end portion in the direction intersecting the paper discharge direction (paper width direction)) 8e slidable with respect to the frame 34 (FIG. 9) constituting the base of the apparatus main body 2. It is supported. Rack portions 8f are formed along the paper discharge direction at both ends of the paper discharge tray 8 (both ends in a direction crossing the paper discharge direction). The rack portion 8f is a rack constituting a rack and pinion mechanism, and a pinion gear (not shown) is engaged with the rack portion 8f. Then, the pinion gear is rotated by the power of a motor (not shown), so that the paper discharge receiving tray 8 is slid. In the present embodiment, the rack portion 8f is formed at both end portions, but may be formed only at one end side.

  An escape portion 8g that avoids the feeding means 9 is formed on the upstream side in the paper discharge direction (left side in FIGS. 4 to 6, left upper side in FIGS. 7 and 8) in the paper discharge receiving tray 8. The escape portion 8g is set so that its width (width in the paper width direction) h is slightly larger than the width of the swing member 11, that is, the swing member 11 can swing inside the escape portion 8g. Has been. In the present embodiment, the feeding reference position in the sheet width direction is set at the center of the sheet, and therefore the relief portion 8g is formed at the substantially center in the sheet width direction.

  The escape portion 8g has the following effects. That is, the paper discharge receiving tray 8 is provided so as to be housed inside the apparatus main body 2. However, when the feeding means 9 and the paper discharge receiving tray 8 are provided so as to overlap with each other in the state of being housed in the apparatus main body, It tends to cause an increase in size (especially an increase in dimension in the height direction).

  However, as described above, the discharge receiving tray 8 is provided with the escape portion 8g that avoids the feeding means 9, so that it is necessary to overlap the feeding means 9 and the discharge receiving tray 8 in the height direction of the apparatus. However, both can be overlapped in the height direction, and an increase in the height dimension of the apparatus can be suppressed.

  Next, on the downstream side of the paper receiving surface 8a in the paper discharge receiving tray 8, a raised portion 8d on which both ends of the paper ride is formed, and both ends of the paper (direction intersecting the paper discharge direction (paper crossing direction)) When both ends in the width direction) ride on, curls are formed on the paper. In FIG. 8, the sheet indicated by the reference symbol P ′ and the phantom line shows a state in which such a curl is formed. Both end portions on the downstream side ride on the raised portion 8d, and in addition to this, the central portion on the upstream side. Curls into the escape portion 8g, so that curl is formed on the paper.

  As a result, it is possible to prevent the leading end of the sheet from protruding from the sheet receiving surface 8a and drooping, and eventually falling. In order to form the curl of the paper as shown in FIG. 8, the escape portion 8g is preferably formed at the center portion in the paper width direction, but the escape portion 8g is formed at the end portion in the paper width direction. Even in such a case, if the raised portions 8d are formed at both ends on the downstream side, it is possible to promote the curl formation on the paper.

  In addition, the discharge receiving tray 8 has a slope 8b formed on the downstream side of the sheet receiving surface 8a for receiving the sheet, that is, the sheet to be supported is configured to be inclined upward. The paper does not easily fall down.

  In the present embodiment, the paper discharge receiving tray 8 is positioned between the lower tray 50 and the upper tray 60 and the recording head 30 in the apparatus height direction, and the paper discharge receiving tray 8 is in the storage position. In some cases (FIG. 4), a clearance L1 (FIG. 4) is formed so that the upstream end 8h does not block the paper feeding path. However, if this clearance L1 is further reduced and the upstream end 8h of the paper receiving tray 8 is formed so as to block the sheet feeding path (the upstream end 8h and the separation slope 16 are almost in contact with each other). State), the paper discharge receiving tray 8, that is, the paper receiving surface 8a can be secured further, and the paper can be received more reliably.

  4 to 6, reference numeral 34 a is a partition plate formed on the frame 34 for partitioning the storage area of the lower tray 50 and the upper tray 60 and the storage area of the paper receiving tray 8. By eliminating the partition plate 34a, the height direction dimension of the apparatus can be further reduced.
