  At the bottoms on both side surfaces of the apparatus main body 2a, there are provided first clue portions 13 that can be handled when carrying the apparatus main body 2a. In the present embodiment, the first hook portion 13 is formed by a dent, and the user carries the device main body 2a by placing a hand on the first hook portions 13 on both sides and lifting the device main body 2a.

  On the other hand, in the paper cassette 5B (more specifically, the unit main body 41) that can be attached to and detached from the bottom of the apparatus main body 2a, the second clue portion 15 formed by a recess is provided in the unit as in the first clue portion 13 described above. Provided at the bottom of both side surfaces of the main body 41. Then, in a state where the unit main body 41 (paper cassette 5B) is mounted on the bottom of the apparatus main body 2a, the user puts his hands on the second clue portions 15 on both sides and lifts the unit main body 41 (paper cassette 5B). The apparatus main body 2a is integrally lifted and transported.

  Here, when the unit main body 41 (paper cassette 5B) and the apparatus main body 2a are to be lifted together in a state where the unit main body 41 (paper cassette 5B) is mounted on the bottom of the apparatus main body 2a, the apparatus main body 2a. If the first clue part 13 on the side is lifted with a hand, the unit main body 41 (paper cassette 5B) may drop from the apparatus main body 2a and fall, causing damage. Such a problem may also occur, for example, when the user attempts to lift the right hand on the first clue part 13 and the left hand on the second clue part 15 (and vice versa).

  The unit main body 41 (paper cassette 5B) and the apparatus main body 2a are connected by connecting means (not shown), and when the unit main body 41 (paper cassette 5B) is removed from the apparatus main body 2a, The connection release lever provided in the connection means is operated to release the connection state. However, the unit main body 41 (paper cassette 5B) is heavy, and when the apparatus main body 2a is lifted, the connecting means cannot always bear the weight of the unit main body 41 (paper cassette 5B). If the paper cassette 5B) and the apparatus main body 2a are connected to each other and the user holds and lifts the first clue unit 13, the connected state may be released.

  As described above, in the state where the unit main body 41 (paper cassette 5B) is connected to the apparatus main body 2a, there is a risk of erroneous handling by the user. Therefore, the ink jet printer 1 according to the present invention shields the first clue unit 13 on the apparatus main body 2a side in the state where the unit main body 41 (paper cassette 5B) is connected to the apparatus main body 2a, so that the first clue unit 13 A shielding means (cover) 17 that makes it impossible to place a hand is provided.

  More specifically, a cover 17 that is rotatable about a shaft 17a is provided above a portion of the unit main body 41 (paper cassette 5B) where the second clue 15 is provided. In the opened state, the cover 17 opens the first clue part 13 as shown in FIG. 3, but when the user closes, the first clue part 13 is shielded as shown in FIG. The first clue unit 13 cannot be handled.

  Therefore, in this state, in the state in which the unit main body 41 (paper cassette 5B) is connected to the apparatus main body 2a, it is possible to effectively prevent a problem that the user puts his hand on the first clue portion 13 on the apparatus main body 2a side and lifts it. It is possible to prevent the unit main body 41 (paper cassette 5B) from dropping off from the apparatus main body 2a and causing damage.

  Protrusions 19 are formed on the inner side of the cover 17, and when the cover 17 is closed, the protrusions 19, 19 are fitted into holes 20, 20 provided on the apparatus body 2a side. Thus, the connection effect between the unit main body 41 (paper cassette 5B) and the apparatus main body 2a is obtained.

  That is, the cover 17 also serves as a connecting means for connecting the unit main body 41 (paper cassette 5B) and the apparatus main body 2a. In the present embodiment, since the connecting means is separately provided as described above, the cover 17 constitutes the second connecting means. However, the unit main body 41 (paper cassette 5B) and the apparatus main body 2a may be connected only by the cover 17.

  Since the cover 17 also serves as a connecting means for connecting the unit main body (paper cassette 5B) and the apparatus main body 2a in this way, there is little possibility that the cover 17 is left open, and the above-described operational effects by the cover 17, that is, The shielding effect of the 1st clue part 13 can be acquired more reliably. However, the connecting means is an arbitrary component, and the effect of the cover 17 (shielding means) can be obtained regardless of the presence or absence of the connecting means.

  In the present embodiment, the cover 17 is configured so that the user can perform the opening and closing operation. However, the present invention is not limited to this. For example, the cover 17 can be provided by attaching the unit main body 41 (paper cassette 5B) to the apparatus main body 2a. An opening / closing mechanism may be provided so as to close. Further, the cover 17 may be opened and closed using a power source such as a motor.

  In the present embodiment, the first clue part 13 functions as a clue part (an area occupied by the user's hand when carrying it) due to its size, and the cover 17 covers almost the entire area. This makes it impossible for the user to place a hand on the first clue unit 13, but it is impossible for the user to place a hand on the first clue unit 13 by shielding a part of the first clue unit 13. It can also be. In addition, even if a part of the first clue unit 13 is shielded and the user can substantially touch the first clue unit 13, a part of the first clue unit 13 is shielded. This makes it difficult for at least the user to hold the hand on the first clue part 13, and thus the operational effects of the present invention can be obtained even with such a shielding form.

  Further, for example, even when the concave portion forming the first clue portion 13 is formed large and only a part of the concave portion constitutes the clue portion, the region where the hand can be inserted when the hand is put is shielded. If this happens, it will be difficult for the user to handle. Therefore, the area to be shielded is not necessarily limited to the area occupied by the user's hand when carrying it, and if the area into which the hand is inserted when the hand is placed is shielded, the user becomes difficult to place the hand and the operational effects of the present invention can be obtained. Can do.

  Next, a second embodiment will be described with reference to FIG. The second embodiment shown in FIGS. 5A and 5B is characterized in that a shutter 21 is used instead of the cover 17 as a shielding means. More specifically, the unit main body 41 ′ (paper cassette 5 </ b> B) is provided with a shutter 21 that can be moved forward and backward with respect to the apparatus main body 2 a side by the shutter drive mechanism 22. When the unit main body 41 ′ (paper cassette 5B) is attached to the apparatus main body 2a, the shutter drive mechanism 22 advances the shutter 21 toward the apparatus main body 2a, and the first clue 13 is shielded. It has become.

  The shutter drive mechanism 22 includes a piston rod 24, a spring 25, a rotary rod 26, and a tension spring 27. The rotating rod 26 is provided so as to be rotatable about a shaft 26a, and by rotating, the shutter 21 is moved from the retracted position shown in FIG. 5 (A) to the advanced position shown in FIG. 5 (B). Advance.

  The piston rod 24 is provided so as to be displaceable in the vertical direction, and is rotated by the protrusion 23 provided on the apparatus main body 2 a side to rotate the rotating rod 26 via the spring 25. The tension spring 27 urges the shutter 21 in the retracting direction (with a weak urging force), and functions to reliably return the shutter 21 from the advanced position to the retracted position.

  The piston rod 24 is configured to rotate the rotating rod 26 via the spring 25 (that is, the shutter 21 is advanced). The user holds the device main body 2a by placing a hand on the first clue 13. This is because when the apparatus main body 2a is placed on the unit main body 41 (paper cassette 5B) and the two are connected, the shutter 21 may pinch the user's hand. Since the spring 25 is interposed between the piston rod 24 and the rotating rod 26, it is possible to prevent the user's hand from being pinched strongly even when the shutter 21 is raised.

  It goes without saying that the embodiment described above is an example and is not limited thereto. For example, in the above-described embodiment, the first clue part 13 formed by the depression is shielded so that the first clue part 13 cannot be hooked. However, the first clue part is not limited to the shield. Any means may be used as long as it does not allow 13 to be touched. That is, any invalidating means for invalidating the first clue unit 13 may be used. The cover 17 and the shutter 21 described above are also examples of such invalidating means.

  For example, when the 1st clue part 13 is comprised by protrusion and a handle instead of a dent, the structure which retracts | projects a protrusion and a handle inside an apparatus, for example can be employ | adopted as an invalidating means. Other than the form of the first clue unit 13, any means that invalidates the first clue unit 13 when the unit main body 41 (paper cassette 5 </ b> B) is mounted on the apparatus main body 2 a may be used. It may be.
