Abstract

PURPOSE:To narrow the width of a machine bed and to reduce the size thereof by constituting hoppers in such a manner that titration plates are housed in a vertical posture. CONSTITUTION:The hoppers 4, 6 are mounted to the machine bed 1 in such a manner that the titration plates 2 are housed therein in the vertical posture. The plate 2 taken out of the hopper 4 is supported by a stage 7 and is moved on a moving base 8 to the under side of a dispensing device 5. The stage 7 is turned 90 deg. as a gear provided to a revolving shaft 82 supporting the stage engages with a rack 91 positioned just before the position below the device 5 and is thereby rotated. The plate 2 is then brought to the horizontal posture so as to be located below the device 5. The gear engages with a 2nd rack 91 and is thereby rotated further 90 deg. when the stage is moved to the under side of the other hopper 6 upon ending of the dispensing operation in said position. The plate 2, therefore, restores the original vertical posture and is housed in the hopper 6. The width of the machine bed 1 is decreased and the size over the entire part of the device is reduced by housing the plates 2 in the vertical posture into the hoppers 4, 5.
