Particularly, in this test apparatus 1, each display unit 12
Since c to 15c are provided in the vicinity of the upper side of the doors 12b to 15b, it is easy for the operator to see and it is possible to call attention when the tray Tr is taken in and out. Therefore, there is a merit that it is possible to effectively prevent the occurrence of an erroneous operation such as a wrong insertion of the tray Tr.

In this embodiment, as shown in Table 1, the use state and the operating state of each tray accommodating section 12 to 15 are displayed based on the displayed color and its lighting state (lighting / blinking). However, it goes without saying that a display method other than this can also be adopted. For example, a plurality of lamps are provided for each tray storage section according to the usage status,
You may make it light these lamps selectively according to the use condition etc. Further, a liquid crystal display device may be provided for each tray storage unit to display the usage state in characters. In this case, since more detailed information can be displayed, for example, the number of remaining parts (trays) or the number of stored parts may be displayed.

Also, the display location is not always the door 12b.
It does not have to be above 15b, and may be provided on the door itself, for example. However, in order to call the operator's attention, it is preferable to provide the doors 12b to 15b or the vicinity thereof.

[0070]

As described above, the component testing apparatus of the present invention can be used in each component storage section to identify at least whether the stored component corresponds to a pre-test component or a post-test component. Since the display means for displaying the status is provided, even if the purpose of use of each component storage part is arbitrarily changed according to the type of the component to be tested, based on the content displayed on the display component. It is possible to easily recognize the usage state of each component storage unit from the outside. for that reason,
It is possible to prevent erroneous work and the like at the time of putting a component in and out of each component storage portion, and improve workability.
