A tablet splitting apparatus includes a guide, a catcher, and a splitting mechanism. The splitting mechanism comprises a pair of blades and a pair of blade shifters. The guide, the catcher, and the splitting mechanism are accommodated in a housing. The housing includes an opening and a support. The support and the guide each include a sliding portion. The guide disposed at the supporting position is slid along the sliding portion of the support so as to be detachable from the supporting position through the opening. The blades and the blade shifters each comprise a sliding portion. The blades and the blade shifters are in a slidable contact with each other at the sliding portions. The blades attached to the respective predetermined positions of the blade shifters are slid along the sliding portions of the blade shifters so as to be detachable from the blade shifters through the opening.

A tablet splitting apparatus includes a plate defining a vertical groove-shaped tablet passage, a catcher for holding a tablet moving downward through the passage at a splitting position, and a mechanism for splitting the tablet at the splitting position. A movable groove-depth defining member faces and covers an upstream part of the tablet passage. A sensor detects a tablet passing through the upstream part of the passage. A controller is responsive to the sensor to activate a mechanism to adjust the distance between the groove bottom surface of the tablet passage and the facing surface of the groove-depth defining member depending on the thickness of the tablet. The apparatus is configured to detect the driving current required to move the cutting blades to automatically determine a time to vary the moving speed of the blades and to release the tablet temporarily held at the splitting position, depending on the thickness of the tablet.
