The lid 3 is opened while the measuring instrument is housed, and measurement is possible. 1 and 3 show the housing case 1 with the lid 3 closed, and FIGS. 2 and 4 show the housing case 1 with the lid 3 open.

  As shown in FIG. 1, the storage case 1 in a closed state has a box shape as a whole. As an example, the case body 2 and the lid portion 3 can be opened and closed so that the opening 6 of the case body 2 can be opened and closed. A slide fastener 4 is attached across the bridge. It is preferable that the slide fastener 4 has two sliders 4a and 4a because the lid 3 can be easily opened and closed. In addition, the case body 2 may be provided with a strap 7 that becomes a handle when being carried.

  As shown in FIG. 2, the case main body 2 is formed so that a portable digital multimeter 51, which is an example of a portable measuring instrument, can be stored together with test leads 52, 52 which are examples of accessories. is there. The test lead 52 can be attached to and detached from the digital multimeter 51 with a connector. The case body 2 may be formed with a capacity (size) that can be stored with the test lead 52 attached to the digital multimeter 51, or may be formed with a size that can be stored together with the test lead 52 removed. .

  The case body 2 has an opening 6 opened so as to be measurable by a digital multimeter 51 accommodated therein. Specifically, the opening 6 of the case main body 2 is displayed so that the display unit 53 and the operation unit 54 of the digital multimeter 51 necessary for performing measurement can be viewed and operated from the outside, and the test leads 52 are provided. Openings are made on the front side of the digital multimeter 51 (the front side of the case body 2) and the top side of the digital multimeter 51 (the top side of the case body 2) so that it can be drawn out to the outside. The opening 6 is formed in a size that allows the digital multimeter 51 to be taken in and out of the case body 2.

  Inside the case body 2, a partition plate 10 that fixes the position of the digital multimeter 51 and separates the storage area for the digital multimeter 51 and accessories may be attached. Although not shown, the case main body 2 may be provided with a fixing tool such as a belt for fixing the position of the digital multimeter 51 and preventing it from falling off the opening 6 as necessary. And the cushioning material for protecting the digital multimeter 51 from an impact may be attached | subjected.

  The lid portion 3 is a strong and flexible material (an example of bendability) such as a resin cloth material, and is formed in a size that allows the opening 6 to be covered. As shown in FIG. 2, one end 3 a of the lid 3 is connected to the top side (upper side in the figure) of the digital multimeter 51 of the back plate 11 of the case body 2.

  The other end 3b of the lid 3 is provided with a permanent magnet 5 such as a neodymium magnet, a samarium cobalt magnet, an alnico magnet, or a ferrite magnet as an example of a magnet. The permanent magnet 5 has a magnetic force capable of supporting the entire weight of the storage case 1 that stores the digital multimeter 51 and the like when attracted to the iron plate. The permanent magnet 5 may be a single long plate or a plurality of rectangular or round plate permanent magnets. In place of the permanent magnet 5, a magnet having a relatively short period during which the magnetic field generation performance can be maintained may be used. Moreover, although electric power is required, an electromagnet may be used.

  As shown in FIG. 3, the back plate 11 of the case main body 2 can be attracted to the permanent magnet at a position where the permanent magnet 5 of the lid 3 in the opened state folded back in the direction opposite to the opening 6 can be attracted. Iron plates 9a, 9b, and 9c (which are also simply referred to as iron plates 9 when not distinguished) are attached at equal intervals. The position of the iron plate 9 is such that when the permanent magnet 5 is attracted, the lid 3 can be loosened without being in close contact with the case body 2. The iron plates 9a to 9c are formed in a surface shape that is substantially the same as or slightly larger than the permanent magnet 5. The iron plate 9 may be replaced with a magnetic member such as a resin plate or a rubber sheet in which a magnetic material such as iron is dispersed. Moreover, you may replace the iron plate 9 with the permanent magnet which is a magnetic member with magnetism.

As shown in FIG. 2, when the permanent magnet 5 of the lid 3 is attracted to an iron member 71 at the measurement site, the storage case 1 is supported in a suspended manner. In this suspended state, the digital multimeter 51 is upright.

  Therefore, even if the measurer is in a place where there is no appropriate base for placing the digital multimeter 51 (storage case 1), the measurer does not hold the digital multimeter 51 in his / her hand, but only holds the test leads 52 and 52. It can be performed.

  In addition, as shown in FIG. 4, the storage case 1 can be suspended and supported by a support body 72 in which the longitudinal direction of beams, handrails, ropes, branches, etc. at the measurement site extends in a substantially horizontal direction. Specifically, the lid portion 3 in the open state indicated by a two-dot chain line in the figure is folded back to the opposite side of the opening portion 6 so as to wind the support 72, and the permanent magnet 5 at the other end portion 3b is attached to the case. The main body 2 is adsorbed to any one of the iron plates 9a, 9b, 9c. Thereby, the support body 72 passes through the ring formed by the lid portion 3 and the case body 2, and the housing case 1 is suspended and supported by the support body 72.

  At this time, since the lid 3 has flexibility, the support 72 can be easily wound and the permanent magnet 5 can be easily attracted to the iron plate 9. Furthermore, when the other end portion 3 b is brought closer to the back side of the case body 2 that is difficult to visually recognize, the other end portion 3 b is made of an iron plate by the magnetic force of the permanent magnet 5 even if the permanent magnet 5 is not accurately aligned with the iron plate 9. 9, it is easy to fix the other end 3 b to the case body 2.

  If a plurality of locations where the permanent magnet 5 is attracted, such as the iron plates 9 a to 9 c, the position where the permanent magnet 5 is attracted is changed according to the thickness of the support 72, or the support 72 and the case body 2 However, if necessary, for example, an iron plate (for example, only the iron plate 9a) may be provided in only one place.

  As shown in FIG. 5, the back plate 11 may be provided with an iron plate 9 d larger than the permanent magnet 5, in this example, an iron plate 9 d having a size covering almost the entire surface of the back plate 11. When such a large iron plate 9d is attached, the weight increases, but the degree of freedom of the position where the permanent magnet 5 is attracted can be increased. Although not shown, for example, a plurality of (for example, two) iron plates having a surface larger than the permanent magnet 5 (approximately half the size of the iron plate 9d) are attached to the back plate 11 at intervals. May be.

  Further, the lid 3 is replaced with a flexible plate that is formed such that, for example, a plurality of hard plates can be bent so that the support 72 can be wound to fix the other end 3b to the case body 2. May be.

  If the measuring instrument is a measuring instrument that does not require accessories for measurement, such as a thermometer with a built-in temperature sensor, a noise meter with a built-in microphone, etc., the case body 2 contains only the measuring instrument. There may be.

  Moreover, although the example which opens the cover part 3 from the front side of the case main body 2 to the top direction side was shown, the cover part 3 opens only the front side of the case main body 2, and the case main body 2 which does not open is shown. You may make it the structure which connects the one end part of the cover part 3 to the opening edge of a top direction side. In this case, the support body 72 is positioned not on the back side of the case body 2 but on the top side, and the storage case 1 is suspended and supported. Since the lid 3 has bendability, the lid 3 can be adsorbed to the iron member 71.

  Further, the lid 3 may be opened and closed from the case main body 2 by attaching a button or a hook-and-loop fastener instead of the slide fastener 4. Accessories included in the storage case 1 include an instruction manual and a spare fuse in addition to those required for measurement such as the test lead 52.
