PURPOSE:To utilize a door to guide a case by providing two doors rotatably freely opposite each other at a case insertion opening, and guiding a case when the case is inserted with two doors. CONSTITUTION:As a case 2 shown by an alternate long and two-dot chain line is inserted into a case insertion opening 20, upper and lower doors 76 and 77 are pushed down, as shown by alternate long and two-dot chain lines, by an insertion force to meet the contact parts 86 and 87 of upper and lower opening bars 84 and 85, so that the doors 76 and 77 do not open any more. The extent of opening between the upper and lower doors 76 and 77 at this time is proper and the case 2 is inserted smoothly. At this time, a door 78 meets the case 2 and the case 2, when further inserted, is guided by a guide member 22. |
