Since it is received at one point, the load on the inspection object 41 is transmitted evenly in the width direction.

  Further, by configuring the inside of the through hole 19c with the curved surfaces 19m and 19n, the contact portion (bottom surface) with the inspection object 41 is configured with a curved surface, so that the inspection object 41 with the pusher 19 tilted. Even if it touches, it can pressurize in the direction near the perpendicular.

Between the through hole 19c and the first shaft 31 of the locking portion 19b, the first shaft 31 is curved 19m, other different curved surfaces 19m and parts in contact with the 19n, 19n portion and the first shaft that there is a clearance between the 31, as shown in FIGS. 14 and 15, the direction pusher 19 back and forth II, can movable flexible in the lateral direction III, to follow with respect to the inclination of the test object 41 Can be pressurized.

  Further, as shown in FIGS. 16 (A) and 16 (B), the inspection apparatus can cope with the structure of the inspection object 41 without changing the structure only by turning the inspection apparatus upside down. is there.

  FIG. 16A shows a state in which the inspection object 41 is connected to the inspection apparatus in a usage state according to the upper contact direction. FIG. 16B shows a state in which the inspection object 41 is connected to the inspection apparatus in a usage state according to the upper contact direction.

  Regarding the second guide member 29, even if the inspection apparatus is turned upside down depending on the contact direction, the second guide member 29 is always set to the first guide member 27 in the same direction without changing the parts.

  When the insertion depth cannot be secured due to the shape of the inspection object 41, the second guide member 29 is removed and used as shown in FIG. In this case, as shown in FIGS. 18 and 19, since the positioning portion 17b is formed in the inner frame 17, the width direction or insertion for positioning the inspection object 41 with only one part of the inner frame. The direction can be accurately positioned.

  A part for positioning the inspection object 41 of the inner frame 17 is manufactured in advance, and removal processing such as cutting is performed according to the width dimension L of the inspection object 41 to flexibly cope with the inspection object 41 of each dimension. To do.

  For the inner frame 17 that needs to be removed depending on the width of the inspection object 41, the common parts of the substrate 11, the base 13, the first guide member 27, the pusher 19, and the first and second shafts 31 and 32 are assembled in advance. Keep it. It becomes possible to change the shape of the board and the connector 15 according to each request.

  In addition, although the method of pushing down the operation member 23 in the way of pinching the laundry basket is adopted for opening and closing the inspection device, a method using a lever to push down the operation member 23 is conceivable.

  Accordingly, since the operation member 23 is lowered when the inspection object 41 is inserted or the lever is lowered, the first and second guide members 27 and 29 can be reliably inserted in the lifted state. It becomes.

  In this embodiment, the arrangement of the elastic bodies and contact portions of the connector 15 has been described in the case of two rows arranged in a staggered manner, but it can also be applied to two rows of parallel arrangement or one row arrangement.

  In the inspection apparatus of the present invention, the second guide member can be removed, and it is possible to cope with an inspection object in which the insertion depth cannot be secured.

  Further, since the pusher that pressurizes the inspection object is moved up and down in conjunction with the operation member by the first shaft, the first insertion port is displaced with respect to the load applied when the inspection object is inserted. There is no.

  Further, since the spring is not used to move the pusher, the loss of members is prevented and the assembly is facilitated.
