Biochemical reaction analyzing apparatus

Claim 2

A biochemical reaction measuring apparatus which performs biochemical reaction measuring processes, including a carrying plate carrying thereon at least one array of cups providing biochemical reaction cells, means for conveying said carrying plate substantially horizontally in the direction of the cup array, and a cup unloading mechanism at a position where the substantially horizontal transportation of said carrying plate terminates, said cup unloading mechanism comprising: means for forming open ended channels, each of said channels having two open ends and into which top parts of said cups on said carrying plate are fitted at said position where transportation terminates, and cup hanging means comprising bar members placed at both sides of said channels and having side edge parts to engage with and hang said arrays of cups fitted in said channels, whereby cups can be both moved into and out of said channels by movement in the same direction.

Claim 3

A biochemical reaction measuring apparatus according to claim 1, including driving means for moving said cup having means between a position where said arrays of cups are fitted into said channels and a position where said arrays of cups are lifted up and discharged out of said channels.

Claim 4

A biochemical reaction measuring apparatus according to claim 2, wherein said driving means comprises means for pivoting said cup hanging means around an axis transverse to the longitudinal direction of said channels.

Claim 5

A biochemical reaction measuring apparatus according to claim 1, including lowering mechanism for lowering said carrying plate installed at the position where the horizontal transportation of said carrying plate terminates and wherein said cup hanging means is fixed.

Claim 6

A biochemical reaction measuring apparatus according to claim 1 or 4, wherein said carrying plate holds a plurality of arrays of cups.

Claim 7

A biochemical reaction measuring apparatus according to claim 1, wherein said cups have peripheral flanges in their top parts which can be engaged with said side edge parts of said bar members which constitute said cup hanging means.

Claim 8

A biochemical reaction measuring apparatus according to claim 1, wherein said cup hanging means comprises a flat-plate type member provided with said channels formed in a lower face thereof.

Claim 9

A biochemical reaction measuring apparatus, comprising: (a) reaction cups having upper openings sealed for providing a space for a reaction, (b) a transfer block for carrying the reaction cups, (c) transporting means for transporting the transfer block, (d) means for breaking the seal sealing the upper openings of the reaction cups, (e) means for pouring a sample to be measured into the reaction cups, (f) means for pouring reagent to react with the sample into the reaction cups, (g) means for measuring a signal produced by the reaction between the sample and the reagent, (h) means for discharging the reaction cups from the transfer block after the measurement, wherein the discharging means has driving means for tilting the transfer block, (i) means for receiving the cups discharged from the transfer block, and (j) lifting-up or lifting-down means arranged on both ends of the transporting means, whereby the reaction cups carried by the transfer block are transported by the transporting means and are subjected to the operations of the seal breaking means, the sample pouring means, the reagent pouring means, the measuring means and finally discharged by the discharging means from the transfer block, and the empty block is lifted down and recycled for further measurement.

Claim 10

A biochemical reaction measuring apparatus, comprising: (a) reaction cups having upper openings sealed for providing a space for a reaction, (b) a transfer block for carrying the reaction cups, (c) transporting means for transporting the transfer block, (d) means for breaking the seal sealing the upper openings of the reaction cups, (e) means for pouring a sample to be measured into the reaction cups, (f) means for pouring reagent to react with the sample into the reaction cups, (g) means for measuring a signal produced by the reaction between the sample and the reagent, (h) means for discharging the reaction cups from the transfer block after the measurement, wherein the discharging means has driving means for tilting the transfer block, (i) means for receiving the cups discharged from the transfer block, and (j) lifting-up or lifting-down means arranged on both ends of the transporting means, whereby the reaction cups carried by the transfer block are transported by the transporting means and are subjected to the operations of the seal breaking means, the sample pouring means, the reagent pouring means, the measuring means and finally discharged by the discharging means from the transfer block, and the empty block is lifted down and recycled for further measurement.
