  By the way, depending on the use environment of the computer, the oil drainage 55 may adhere to the gap between the touch panel operation surface 50 and the frame-shaped member 51. When the computer is installed with the posture in which the touch panel operation surface 50 stands up, the attached amount of the oil 55 increases particularly in the region surrounded by the lower side of the frame-shaped member 51 and the touch panel operation surface 50 and the packing 52. In consideration of this, a type of packing that absorbs the waste oil 55 may be used as the packing 52.

  However, when the packing 52 is of a type that absorbs the drained oil 55, the amount of drained oil that the packing 52 holds has a limit. The packing 52 is pressed against the touch panel operation surface 50 by the frame-shaped member 51. For these reasons, there may occur a situation in which the drained oil oozes out from the packing 52 into the storage space 53 of the computer. The spilled oil can cause a computer failure.

(Second Embodiment)
The second embodiment according to the present invention will be described below.

  The case of 2nd Embodiment which concerns on this invention is a member which comprises the panel computer (apparatus with a case) which is a computer provided with the touch panel, and the said case accommodates the apparatus main body of a panel computer. The device body to be accommodated includes a protection target area protected by a case and a touch panel operation surface that is an outward surface that needs to be exposed to the outside. The panel computer including the case of the second embodiment is assumed to be installed with a posture in which the touch panel operation surface stands up. Specific examples of the panel computer include a computer device that accepts an order from a restaurant and a machine tool control device.

  The case of the second embodiment includes a frame-like member (bezel) 21 as shown in FIG. 4 in order to expose the touch panel operation surface to the outside. The frame-shaped member 21 has a form that surrounds the peripheral edge of the touch panel operation surface 22, and the touch panel operation surface 22 is exposed from the opening surrounded by the frame-shaped member 21. The frame-like member 21 in the case 20 of the second embodiment prevents the drained oil adhering to the touch panel operation surface 22 from gradually falling along the touch panel operation surface 22 and collecting on the lower side of the touch panel operation surface 22. It has a configuration to do. FIG. 3 is a diagram schematically showing a cross section of the component (a cross section taken along the line A-A shown in FIG. 4) of the frame-shaped member 21 that prevents the waste oil from accumulating. FIG. 5 is a perspective view schematically showing a state in which the constituent parts are viewed from the touch panel operation surface 22 side (case inner side). FIG. 6 is a perspective view schematically showing an example of the relationship between the frame-like member 21 and the elastic member 28 shown in FIG. In addition, the right end surface of the frame-shaped member 21 in FIGS. 5 and 6 represents a virtual cross section.

  The frame-like member 21 in the case 20 of the second embodiment has a protruding wall 24, a pressing wall 25, and an extending wall 26.

  The pressing wall 25 is a part that presses the peripheral edge of the touch panel operation surface 22 via the elastic member 28, and the elastic member 28 causes the protection target region 31 of the apparatus body 30 to be protected as shown in FIG. 3. The case internal space 33 to be accommodated is sealed.

  The protruding wall 24 is a part that protrudes from the pressing wall 25 toward the outside of the case internal space 33 along the touch panel operation surface 22. In the second embodiment, the protruding wall 24 protrudes toward the touch panel operation surface 22 from the pressing wall 25, and there is a step at the boundary between the protruding wall 24 and the pressing wall 25. As shown in FIG. 6, the step 36 is a part for positioning the elastic member 28 by locking the elastic member 28.

  The extending wall 26 is a part extending from the pressing wall 25 to the side covering the case internal space 33.

  In the second embodiment, a series of case parts having the protruding wall 24, the pressing wall 25, and the extending wall 26 will be referred to as a sealing wall 35. As shown in FIG. 5, the sealing wall 35 is formed with a recess 37 extending from the protruding wall 24 to the pressing wall 25 at a portion facing the touch panel operation surface 22 (case internal space 33). ing. The concave portion 37 has a continuous opening portion of an opening portion 38 formed in the protruding wall 24 and an opening portion 39 formed in the pressing wall 25.

  Further, as shown in FIG. 3, a discharge port 40 is formed on the outer wall surface of the sealing wall 35 (the pressing wall 25). The discharge port 40 is formed at a position below the introduction port 38 in the assumed usage state of the case 20 (a state where the touch panel operation surface 22 is raised). Furthermore, a through hole 41 extending from the concave surface of the concave portion 37 to the discharge port 40 is formed in the sealing wall 35. FIG. 7 is a schematic perspective view when the outer wall surface of the sealing wall 35 including the discharge port 40 is viewed from the outside.

  In the second embodiment, in the recess 37 of the sealing wall 35, the opening 38 formed in the protruding wall 24 functions as an inlet for draining oil or the like. Further, the opening 39 formed in the pressing wall 25 is closed by the elastic member 28. Thereby, the part of the recessed part 37 formed in the pressing wall 25 forms a passage, and the passage constitutes a discharge passage 42 connecting the introduction port 38 and the discharge port 40 together with the through hole 41. In the second embodiment, as described above, the discharge port 40 is formed at a position below the introduction port 38 in the use state. Therefore, the discharge passage 42 is a passage that tends to descend from the introduction port 38 toward the discharge port 40. As a result, the drained oil or the like that has entered from the introduction port 38 is discharged from the discharge port 40 to the outside through the discharge passage 42 due to gravity.

  In the second embodiment, one or a plurality of such discharge passages 42 are formed in the lower side portion of the frame-shaped member 21. The number of the discharge passages 42 is appropriately set in consideration of the size and shape of the frame-like member 21. The passage cross-sectional area of the discharge passage 42 is appropriately designed in consideration of the size and shape of the frame-shaped member 21, the viscosity of the drain oil, and the like.

  The case 20 in the second embodiment can discharge the oil discharged from the area surrounded by the touch panel operation surface 22, the elastic member 28, and the protruding wall 24 to the outside through the discharge passage 42 by gravity. Thereby, the case 20 can prevent the problem that the oil collected on the lower side of the touch panel operation surface 22 penetrates the case internal space 33 through the elastic member 28. That is, the case 20 can prevent a situation in which the apparatus main body 30 accommodated due to the drained oil that has entered breaks down. For this reason, the case 20 in this 2nd Embodiment can improve the reliability with respect to durability of an apparatus.

  In the second embodiment, the recess 37 formed in the sealing wall 35 is closed by the elastic member 28, so that many portions of the discharge passage 42 are configured. In such a configuration, as compared with the case where the buried discharge passage 42 is formed inside the sealing wall 35, it is not necessary to form a passage wall on the case inner space 33 side that forms the discharge passage 42. Can be made thinner.

  Further, in the second embodiment, the introduction port 38 faces the touch panel operation surface 22 (inside), so that the oil to be introduced can be introduced and dust and the like are difficult to enter. As a result, the introduction port 38 can be prevented from being clogged with dust.

(Other embodiments)
The present invention is not limited to the first and second embodiments, and various embodiments can be adopted. For example, in the first and second embodiments, a surface treatment that makes it difficult for oil to adhere to the passage inner wall surfaces of the discharge passages 9 and 42 (that facilitates oil flow) may be performed.
