The operation panel 10 and the cover body 20 are inclined so as to be positioned forward as going downward. That is, the operation panel 10 and the cover body 20 are inclined forward.

  As shown in FIG. 2, the operation panel 10 is provided with a plurality of operators 11 including push buttons and a display screen 12. The operation element 11 may be anything that is operated by the user's hand, and the type thereof is not limited at all. In the present embodiment, the operation panel 10 is formed in a circular shape. Some of the controls 11 are arranged obliquely forward and below the center 10 c of the operation panel 10.

  The cover body 20 is disposed so as to surround the operation panel 10. The cover body 20 has a protruding portion 21 and a front cover portion 22. As shown in FIG. 3, the protruding portion 21 protrudes to the front side from the operation panel 10. The operation panel 10 and the front cover portion 22 are preferably located on substantially the same plane. In this embodiment, the operation panel 10 and the front cover part 22 are located on the same virtual plane P1. However, the operation panel 10 and the front cover part 22 do not necessarily have to be located on the same plane.

  As shown in FIG. 2, the protruding portion 21 has a front side portion 21 a that is located on the diagonally lower front side of the operation panel 10. The size and range of the front portion 21a can be appropriately set according to the shape of the operation panel 10, but in this embodiment, there is a range within 45 degrees from the vertical line passing through the center 10c of the operation panel 10. It becomes the front side part 21a. In the present embodiment, the operation panel 10 is formed in a circular shape, but the shape of the operation panel 10 may be other than a circular shape. In this case, the position of the center 10c of the operation panel 10 may be a center position when it is assumed that the shape of the operation panel 10 is a circle having the same area. FIG. 3 is a view showing a vertical cross section of the operation panel 10 and the cover body 20 that passes through the center 10c of the operation panel 10 and extends in the front-rear direction. Here, the “vertical section” is a section including a vertical line. Reference numeral 13 represents a center line of the operation panel 10. Reference sign L1 represents the length of the front portion 21a in a direction parallel to the operation panel 10 (hereinafter referred to as a surface direction). Reference numeral L <b> 2 represents the length of the front cover portion 22 in the surface direction. The length L2 of the front cover portion 22 in the surface direction is longer than the length L1 of the front side portion 21a in the surface direction.

  As shown in FIG. 2, the front portion 21 a includes a rear end edge 24 that forms an arc centered on the center 10 c of the operation panel 10, and a front end edge 23 that forms an arc that is substantially concentric with the rear end edge 24. ing. Thus, since the rear end edge 24 and the front end edge 23 form a concentric arc, the length in the radial direction around the center 10c in the front portion 21a is constant. As a result, the front portion 21a is formed so that the length in the surface direction in the vertical section is substantially uniform from the left side to the right side. For example, the lengths L1, L12, and L13 in FIG. 2 are substantially equal.

  As described above, the outer shape of the operation panel 10, that is, the inner peripheral edge of the protruding portion 21, is formed in a perfect circle shape. However, the outer shape of the operation panel 10 may be other shapes, for example, a quadrangular shape, a hexagonal shape, an elliptical shape, or the like. The outer shape of the operation panel 10 is not particularly limited. For example, when the outer shape of the operation panel 10 is a square shape, the front end edge of the front side portion 21a is linear so that the length in the surface direction in the vertical section of the front side portion 21a of the protrusion 21 is substantially uniform. It may be formed.

  A symbol L4 in FIG. 2 represents the center line of the cover body 20 in the left-right direction. The distance between the left end 25L of the cover body 20 and the center line L4 is equal to the distance between the right end 25R of the cover body 20 and the center line L4. As shown in FIG. 2, when the ink head 3 is in the standby position, that is, the home position, at least a part of the ink head 3 is located on the right side of the center line L4. When the ink head 3 is located at the home position, the nozzle surface of the ink head 3 is covered with a capping device 35 to prevent drying.

  The front cover portion 22 has a front inclined surface 22 a located on the platen 4 side with respect to the operation panel 10. In other words, the front cover portion 22 is located on the left side of the operation panel 10 and has a front inclined surface 22 a that is inclined at substantially the same inclination as the operation panel 10. Here, the operation panel 10 is disposed on the right side of the center line L4, and the forward inclined surface 22a is disposed on the left side of the center line L4. The forward inclined surface 22a is located rearward and obliquely above the front obliquely lower end portion 10b of the operation panel 10. Since the protruding portion 21 protrudes to the front side, a step 30 is formed between the protruding portion 21 and the front cover portion 22 (see FIG. 3). As described above, the projecting portion 21 includes the arc-shaped front end edge 23, and the front cover portion 22 has the front inclined surface 22 a located on the platen 4 side with respect to the operation panel 10. Therefore, the step 30 has a shape that follows the shape of the operation panel 10 on the diagonally lower front side of the operation panel 10 and has a shape that extends diagonally upward on the platen 4 side of the operation panel 10. Yes. In the present embodiment, the left end portion of the step 30 extends in the left-right direction.

It has a front cover portion 22 that is formed to fit and is lower than the protruding portion 21. As a result, a step 30 is formed at least on the obliquely lower front side of the operation panel 10. Therefore, as shown in FIG. 2, the user can easily operate the operation panel 10 while placing the hand 40 on the step 30. Further, by searching for the position of the step 30 with the hand 40, the hand 40 can be easily moved to the operation position. Therefore, it becomes easy to operate the operation panel 10 while visually checking the printing state. In addition, in this embodiment, although the height of the protrusion part 21 in the front part 21a, ie, the level | step difference 30, was 1 cm, the height of the protrusion part 21 can be changed suitably.

  As shown in FIG. 3, the operation panel 10 and the front cover part 22 are located on the same virtual plane P1. Therefore, operation of the operation panel 10 becomes easier.

  As shown in FIG. 3, the length L2 in the surface direction of the front cover portion 22 is longer than the length L1 in the surface direction of the front portion 21a of the protrusion 21. Thereby, it becomes easier to apply the hand 40 to the step 30, and the operation panel 10 can be operated more easily.

  As shown in FIG. 2, the front portion 21 a of the protrusion 21 is formed so that the length in the surface direction is substantially uniform from the left side to the right side. Thereby, the operation of the operation panel 10 is further facilitated.

  As shown in FIG. 2, the front portion 21 a of the protruding portion 21 has a rear end edge 24 that forms an arc centered on the center 10 c of the operation panel 10, and a front end edge 23 that is substantially concentric with the rear end edge 24. Is formed. Thereby, the operation of the operation panel 10 is further facilitated.

  By the way, when the user operating the operation panel 10 moves to the platen 4 side in order to visually check the printing state of the recording paper 9, the hand 40 is released from the cover body 20 or on the cover body 20. The hand 40 must be shifted to the platen 4 side. According to the present embodiment, the front cover portion 22 has a forward inclined surface 22 a, and the step 30 extends not only to the front diagonally lower side of the operation panel 10 but also to the platen 4 side. Therefore, when visually checking the printing state, it is only necessary to move the hand 40 to the platen 4 side along the step 30, and when returning to the operation panel 10 side again for operation, the hand 40 is moved along the step 30. The hand 40 can be returned to the operation panel 10 simply by returning the hand 40. Therefore, the operation of the operation panel 10 and the visual inspection of the printing state can be easily repeated.

  In the present embodiment, the operation panel 10 is disposed on the right side of the center line L4, and the forward inclined surface 22a is disposed on the left side of the center line L4. Further, the forward inclined surface 22a is arranged obliquely above and rearward of the front obliquely lower end portion 10b of the operation panel 10. Thereby, a wide inclined surface is formed on the left side portion of the cover body 20. Therefore, the hand 40 can be easily moved along the step 30.

  In addition, the protrusion part 21 and the front cover part 22 of the cover body 20 may be formed separately, and may be assembled together. However, in this embodiment, the protrusion part 21 and the front cover part 22 are integrally molded. Therefore, it is possible to reduce the number of parts of the inkjet printer 1 and the number of assembly steps.

  In the embodiment, the operation panel 10 and the cover body 20 are disposed on the right side of the platen 4. However, the operation panel 10 and the cover body 20 may be disposed on the left side of the platen 4.
