Description

  In the present invention, for example, a case body in which a measuring instrument is integrally formed so that a probe can be housed is formed. This is a technique related to a casing structure that is attached with a structure that can be opened with a good closing performance.

  Various casing structures that can be safely stored without damaging or dissipating various articles have been proposed in the past.

  If such a casing structure is described in relation to a measuring instrument for measuring electrical characteristics, a first measuring instrument is housed in a case provided with an upper lid not having a probe accommodating portion. Integrated with the conventional type, the second conventional type in which the case body integrated with the measuring instrument and the upper lid not having the probe storage portion are detachably formed under a double hinge structure, and the measuring instrument There is a third conventional type in which an upper lid having a probe storage portion is detachably attached to a case body formed in the above.

  In this case, according to the first conventional type, since the measuring device is separate from the case, there is an advantage that the size can be reduced without being restricted by the size of the case. According to the second and third conventional types, There was an advantage that the upper lid could be removed.

  Of these, the third conventional type casing structure is common to the present invention in that the probe can be accommodated. For example, the upper lid having the probe accommodating portion can be attached to and detached from the case body formed integrally with the measuring instrument. It is attached and formed in its entirety.

  However, in the case of the above type of casing structure, since the probe storage portion is formed using the inner surface of the upper lid, the probe cord must always be fixed with a belt. There was an inconvenience that it was bad.

  In addition, although the upper lid can be removed from the case main body, it has to be placed beside the measuring operation as a separate body from the case main body, which hinders the operation.

  Further, the upper lid needs to be formed using a soft material different from that of the case body 1, and the structure is relatively complicated, which increases the product cost.

For this reason, as shown in the following Patent Document 1, the present applicant, unlike the conventional types described above, can obtain a preferable finish when the upper lid is opened, and can easily store various items such as probes, In addition, a versatile casing structure that can simplify the structure and effectively contribute to cost reduction has already been proposed.

  Further, on the peripheral plate portion 8 side of the upper lid 7, a support shaft portion 9 having a circular cross section guided and moved by the guide groove 5 is provided. For this reason, in order to open the upper lid 7 and lay it under the bottom plate 2 of the case body 1, first, the upper lid 7 is opened 90 degrees or more so as to be tilted backward via the support shaft portion 9. After dropping downward along the vertical groove portion 6a, and further opening from the state of the lid to 180 degrees, the upper lid 7 is moved along the horizontal groove portion 6b of the guide groove 6 via the support shaft portion 9. It was necessary to move it and lay it under the bottom plate 2 of the case body 1.

  However, in the case of the casing structure of Patent Document 1 shown in FIGS. 3 and 4, the vertical groove 5 a that opens the upper lid 7 90 degrees before the upper lid 7 is opened and laid under the bottom plate 2 of the case body 1. It is necessary to perform a moving operation with four actions: dropping along the top, opening the upper lid 7 up to 180 degrees, and moving along the horizontal groove 5b. There was an inconvenience that was not necessarily smooth.

  According to the present invention, while taking into account the convenience provided by the casing structure of Patent Document 1, the operation from the opening of the top cover to the laying under the bottom plate of the case body can be easily performed by a moving operation with two actions. An object of the present invention is to provide a casing structure that can be used.
