JP2903273B

The present cartridge comprises, a casing wherein a plurality of the dry analytical flim chips having at least one reagent layer provided on a support are stacked, an exit for taking out the end dry analytical film chip of the stack one by one, an urging means for pushing the dry analytical film chip stack toward the exit, an engaging means for inhibiting the discharge of the end dry analytical film chip of the stack from the casing, and an opening for passing the conveying means of the dry analytical film chip to be taken out, wherein the exit and the engaging means for inhibiting the discharge of the end dry analytical film chip are provided at an end portion of a side wall of the casing, the opening is provided at a end of the casing, and the engaging means for inhibiting the discharge of the end dry analytical film chip is a flexible engaging means having a strength capable of releasing the end dry analytical film chip by the conveying means but capable of holding the second end dry analytical film chip, wherein the exit and the engaging means for inhibiting the discharge of the end dry analytical film chip are provided at an end portion of a side wall of the casing, the opening is provided at a end of the casing, and the engaging means for inhibiting the discharge of the end dry analytical film chip is a flexible engaging means for the end film chip having a strength capable of releasing the end dry analytical film chip by the conveying means, and an engaging means capable of holding the second end dry analytical film chip is further provided, or wherein the exit and the engaging means for inhibiting the discharge of the end dry analytical film chip are provided at an end portion of the casing, and the engaging means for inhibiting the discharge of the end dry analytical film chip is a non-flexible engaging means having a size capable of releasing the end dry analytical film chip by its deformation occurring by the pull of the conveying means but capable of holding the second end dry analytical film chip through the release of the end dry analytical film chip, and the exit also functions as the opening. The cartridge can eject surely one dry analytical film chip (preventing from simultaneous two chips ejection) with a simple structure keeping a compact size.
