First, the configuration of the printer 1 will be outlined with reference to FIGS. 1 and 2. The printer 1 is configured as a small size suitable for recording on a recording sheet such as a postcard having a relatively small size or an L size as an example of “recording medium” or “jetting medium”.
In the same way as an ink jet printer suitable for A4 size recording, this printer 1 reciprocates a feeding device (ASF) 2 capable of setting a plurality of recording sheets in an inclined posture at the rear of the device in the main scanning direction in the middle of the device. A carriage (not shown) having a recording head (not shown) provided movably is provided, and a stacker 13 for stacking recorded recording sheets is provided at the front of the apparatus. When not in use, the stacker 13 is in a stowed state in which it is erected substantially vertically as shown, and in use, the stacker 13 is opened to the front side of the printer and is in a use state in which recording sheets can be stacked (not shown).

  An operation unit 5 including a power button, a print setting button, and the like, and a display unit 4 for displaying print setting contents, current operation status, and the like are arranged at the center of the upper surface of the apparatus. Is provided with a card slot 16 (see FIG. 2) into which a semiconductor memory medium (memory card) storing the above can be inserted and removed, and a cover 14 that can be opened and closed. That is, the printer 1 not only connects to an external host computer and receives print data, but also reads image data directly from a memory card storing image data, generates print data, and executes printing by itself. It is configured to be possible.

  Next, the housing (housing) constituting the external appearance of the printer 1 is constituted by a plurality of members as shown in FIG. The apparatus body is mounted on the lower housing 8, and the upper housing 7 is attached to the upper part of the apparatus body. A side housing right 9 and a side housing left 11 that form a cap shape are mounted on the main body portion constituted by the lower housing 8 and the upper housing 7 so as to cap from the left and right, and these side surfaces are provided with the present embodiment. In the form, the plates 10 and 12 serving as a decorative plate are detachably attached.

  Further, a handle 6 is rotatably attached to the side housing right 9 and the side housing left 11 (details will be described later), whereby the printer 1 can be easily transported by grasping the handle 6 during carrying. Is possible. Even when the handle 6 is used to support the main body that is divided vertically by the lower housing 8 and the upper housing 7, the side housing right 9 and the side housing left 11 are capped from the left and right as described above. Therefore, the body portion does not separate vertically when the handle 6 is gripped and transported, and the safety during transport (that is, the mechanical strength of the housing) is improved. .

  Next, the mounting structure of the stacker 13 will be described. As shown in FIG. 3, guide plates 20 are formed on the front side of the lower housing 8 so as to rise substantially perpendicularly from the lower housing 8 and parallel to the front surface of the printer 1. Ribs 18 and 19 are formed at the ends so as to extend upward from the lower housing 8 so as to be substantially orthogonal to the guide plate 20 and to protrude to the front side of the printer 1.

  At the upper ends of the ribs 18 and 19, slits are formed in the direction in which the ribs 18 and 19 extend, and thereby elastic deformation portions 18a and 19a are formed, respectively, which are close to and away from the side surface of the stacker 13. Locking projections 18b and 19b are formed on the inner side (the side desired by the stacker 13) of the elastic deformation portions 18a and 19a.

  On the other hand, the stacker 13 is pivotally attached and pivoted by fitting a projection 13b (see FIG. 5) serving as a pivot shaft into bearings 18c and 19c formed under the ribs 18 and 19. As shown in FIG. 3, the state is switched between a use state opened to the near side and a storage state standing substantially vertically. Locking holes 13a are formed in both side walls of the stacker 13 (shown only on one side in FIGS. 3 to 5). When the stacker 13 is in the retracted state, the elastic deformation portion 18a is elastic as shown in FIG. Due to the deformation, the locking projection 18b is fitted into the locking hole 13a, whereby the stacker 13 is held in the stored state.

  Here, since the ribs 18 and 19 have a rib shape extending upward from the bearing portions 18c and 19c which are the rotation fulcrum (base end side) of the stacker 13, the slits forming the elastically deformable portions 18a and 19a are formed. The degree of freedom in length is improved, and this makes it easy to adjust the holding force for holding the stacker 13. In addition, the means for holding the stacker 13 can be installed in a small space.

  In the stacker 13, as shown in FIG. 5, a rib 13d extending in the discharge direction is formed at the tip of the stacker so as to be localized in the paper width direction. This is because the cavity 13c is formed at the tip of the stacker 13 to prevent sink marks during resin molding, so that the leading edge of the discharged recording paper is prevented from entering the cavity 13c. Therefore, the rib 13d is formed so that the recording paper is away from the paper support surface of the stacker 13 and is directed upward.

  Next, means for preventing an impact when the cover 14 is opened will be described. As shown in FIGS. 1 and 2, the cover 14 covering the card slot 16 has a vertically long shape and forms an appearance on the right side of the front surface of the printer 1. As shown in FIG. 6 (A), a rotating shaft 15 is pivotally supported by bearing portions 9e and 9f on the bottom of the front surface of the side housing right 9 to which the cover 14 is attached. The grip portions 14a and 14b formed in the above are fitted in a snap-fit manner, whereby the cover 14 is rotatably attached with the vicinity of the bottom of the printer 1 as a rotation fulcrum.

  Here, a protrusion 14c is formed on the side surface of the gripping portion 14a as shown in FIG. 6B, and the protrusion 14c is shown in FIGS. 7A and 7B when the cover 14 is attached. As shown, the bearing portion 9f enters the groove 17 formed in an arc shape, and the projection 14c is displaced inside the groove 17 as the cover 14 rotates. A convex portion 17 a is formed inside the groove 17, and the projection 14 c is moved to a position indicated by reference numeral 14 c ′ as the cover 14 rotates (the projection 14 c in the state where the cover 14 covers the card slot 16). Position) to move to the position indicated by reference numeral 14c ″ (the position of the protrusion 14c when the cover 14 opens the card slot 16) to engage with the protrusion 17a to reduce the rotational speed of the cover 14. It is like.

That is, the cover 14 has a shape that is long in the vertical direction, and rotates at the lower part thereof as a rotation fulcrum. Therefore, a large impact may be applied when opening the front of the apparatus. It is designed to prevent the occurrence of noise and damage.
The cover 14 is provided with a metal piece (not shown). On the other hand, on the side of the side housing right 9, a magnet (not shown) is placed at a position corresponding to the metal piece, using a mounting tongue piece (not shown). Therefore, it is firmly attached so as not to easily fall off. Accordingly, the cover 14 is held closed by the magnet attracting the metal piece.

  Subsequently, a coupling structure of the upper housing 7, the lower housing 8, the side housing right 9, and the side housing left 11 and a mounting structure of the handle 6 will be described.

  As described above, the housing constituting the external appearance of the printer 1 has a configuration in which the side housing right 9 and the side housing left 11 are capped to the main body portion constituted by the upper housing 7 and the lower housing 8. However, the side housing right 9 and the side housing left 11 are attached by a simple attachment structure such as a snap-fit structure.

  8 and 9 show a structure for attaching the side housing left 11 to the upper housing 7 and the lower housing 8, and holes 7a and 7b are formed on the upper surface of the upper housing 7 as shown in FIG. On the other hand, protrusions 11a and 11b are formed on the side of the side housing left 11 so as to correspond to the positions of the holes 7a and 7b, respectively, so that the protrusion 11a is inserted into the hole 7a and the protrusion 11b is inserted into the hole 7b. It has become. Further, as shown in FIG. 9, a hole 8b is formed on the bottom surface of the lower housing 8, while a protrusion 11c is formed on the side of the left side housing 11 so as to correspond to the position of the hole 8b. It fits into the hole 8b in a snap-fit manner. As described above, the housing can be easily assembled with a simple mounting structure.

  In addition, although the side housing left 11 side was demonstrated above, the attachment structure to the upper housing 7 and the lower housing 8 of the side housing right 9 is also the same. Further, as shown in FIG. 10, since the opening 9d is formed at the position of the card slot 16 in the side housing right 9, the user puts his / her finger on the peripheral edge 9g (free end side) of the opening 9d and moves upward. As a result, the peripheral edge 9g of the opening 9d may be damaged. Therefore, in the present embodiment, the fitting portion composed of the protrusion 9a and the hole 7c is disposed in the vicinity of the opening 9d, thereby preventing the peripheral edge 9g of the opening 9d from being damaged. Reference numeral 23 denotes a mounting screw that is screwed into the screw hole 7e through the hole 9h, and the side housing right 9 (same as the side housing left 11) is securely fixed to the upper housing 7 by the mounting screw. It is supposed to be done.

  Next, the attachment structure of the handle 6 will be described. As shown in FIG. 11, the handle 6 has a substantially U-shape, and shaft portions 6 a and 6 b projecting inward at both end portions are pivotable to the side housing right 9 and the side housing left 11. It has come to be supported. In addition, although the side housing left 11 side is demonstrated below, the side housing right 9 is also comprised similarly.

  In FIG. 11, a hole 12 a for inserting the shaft portion 6 b is formed in the plate 12 detachably attached to the side housing left 11 in a snap-fit manner, and the shaft portion 6 b is inserted into the side housing left 11. A hole 11e is formed, and a bearing portion 22 that pivotally supports the shaft portion 6b is formed. As shown in FIG. 12, the bearing portion 22 has a flange shape protruding outward so as to pass through the hole 12a formed in the plate 12, and the protruding flange shape is just fitted into the hole 12a. It has become.

  The shape of the shaft portion 6b and the hole 11e will be described in more detail. The shaft portion 6b is formed with locking projections 6c and 6d that protrude in a direction orthogonal to the axial direction as shown in FIG. The locking protrusion 6e is formed with a protrusion 6e that protrudes in the direction opposite to the extending direction of the shaft portion 6b. On the other hand, as shown in FIG. 13B, the hole 11e has a shape such that the shaft portion 6b having the shape as described above is fitted, and once the shaft portion 6b is inserted into the hole 11e, As shown in FIG. 14, except for the state in which the handle 6 is at a predetermined angle, the locking projections 6c and 6d are locked to the peripheral edge of the hole 11e, so that they do not fall out of the hole 11e. FIG. 13B is a view of the hole 11e as seen from the inside of the left side housing 11, and the shaft portion 6b is inserted from the back side to the front side.

  A recess 11f is formed in the vicinity of the hole 11e. The recess 11f is a hole into which the protrusion 6e formed in the shaft portion 6b is inserted. As shown in FIG. 14A, the protrusion 6e is inserted into the recess 11f, so that the rotation operation of the handle 6 is restricted. The handle 6 is fixed with respect to the main body of the printer 1 (in this embodiment, the handle 6 is fixed in a substantially vertical state). Accordingly, even when the printer 1 is lifted by holding the handle 6, the printer 1 can be stably transported without being unstablely swung, and the ink generated when the posture of the printer 1 is tilted. It is possible to prevent problems such as spillage. Reference numeral 11g denotes a guide groove that guides the protrusion 6e when the handle 6 is rotated. The guide groove 11g defines a range in which the handle 6 can be easily rotated. .

  The following effects can be obtained by the mounting structure of the handle 6 configured as described above. That is, when the printer 1 is lifted by holding the handle 6, the weight of the printer 1 is concentrated on the bearing portion 22, so that the bearing portion 22 is damaged during carrying or the shaft portion 6 b on the handle 6 side. May be damaged. However, according to the configuration as described above, the contact area between the handle 6 and the bearing portion 22 is increased by the flange shape, and therefore the load acting between the two is dispersed, so that stress concentration does not occur. The shaft portion 6b and the bearing portion 22 can be prevented from being damaged.

Further, a locking piece 12b formed in the plate 12 and a hole 11d formed in the side housing left 11 constituting a part of a snap fitting portion for attaching the plate 12 to the side housing left 11 in a snap-fitting manner, Since the plate 12 is configured to be attached to the side housing left 11 so as not to be displaced upward, when the printer 1 is lifted through the handle 6, the flange shape of the bearing portion 22 is the hole 12a, Since it is supported by the plate 12, even if a load is applied to the bearing portion 22, the plate 12 bears a part of the load, and the strength of the bearing portion 22 can be further improved to prevent the occurrence of breakage or the like. It becomes possible.
In the above-described embodiment, the plate 12 is attached by a snap-fit structure. However, the present invention is not limited to this, and it is needless to say that the above-described effects can be obtained even if the plate 12 is attached by various attachment means.

  By the way, on the back side of the left side housing 11, an interface section 26 having female connectors 24 and 25 for connecting to external devices is provided as shown in FIG. For example, as shown in FIG. 15B, when the male connector 27 is inserted into the female connector 25 in a state where the handle 6 is lowered, and the handle 6 is grasped and lifted upward in this state, the handle 6 There is a possibility that the male connector 27 interferes and the female connector 25 or its surrounding mounting portion may be damaged in some cases. However, in the present embodiment, the flange 11h is formed on the left side housing 11 so as to cover the upper part of the inserted male connector 27. Even when the handle 6 and the male connector 27 interfere with each other, the male connector 27 is formed. The upward displacement is regulated by the flange 11h. Accordingly, this prevents the female connectors 24 and 25 or the surrounding mounting portions from being damaged.
