An objective of this invention is to realize a tablet dividing apparatus capable of easily and simply attaching and detaching a blade 41 of a cutting mechanism 40. The tablet dividing apparatus includes a falling tablet-guiding member 31 engraved with a tablet falling path 32, a cutting mechanism moving the blade 41 forward or backward at a cutting position in the middle of the path 32, and a main body 24 formed with an opening 54, wherein the falling tablet-guiding member 31 is slidably engaged with / detached from a supporting member 28, the blade 41 is also slidably engaged with / detached from a blade stroking member 43, and the sliding directions of these members are parallel with each other and faces to the opening 54. Moreover, when a plate-like tool body 61 of a remover 60 (blade switching tool) capable of being slidably engaged with / detached from the supporting member 28 is temporarily engaged with the supporting member 28 and inserted to the main body 24 from the opening 54 instead of the falling tablet-guiding member 31, the blade 41 which has been mounted onto the blade stroking member 43 is captured by a blade holder 64 and is removed from the main body 24 together with the remover 60.本發明之課題在實現可容易且輕鬆地安裝拆卸切斷機構40的刀刃41之錠劑分割裝置。本發明具備有凹入形成有錠劑落下路徑32之落下錠劑導引構件31、使刀刃41在路徑32的途中之切斷位置前進後退之切斷機構、及形成有開口54之本體部24,且落下錠劑導引構件31與支持構件28藉由滑動而相卡合/分離,刀刃41與刀刃進退構件43亦藉由滑動而相卡合/分離,且該等的滑動方向相平行且朝向開口54。另外,使可藉由滑動與支持構件28相卡合/分離之拆卸器60(刀刃更換工具)的板狀的工具本體部61代替落下錠劑導引構件31從開口54插入本體部24暫時與支持構件28卡合然後拔出時,裝設於刀刃進退構件43之刀刃41就會為刀刃保持部64所捕捉而與拆卸器60一起從本體部24中出來。20‧‧‧錠劑分割裝置21‧‧‧錠劑盒22‧‧‧操作部23‧‧‧控制裝置24‧‧‧本體部(框體)25‧‧‧承接器26‧‧‧中繼部27‧‧‧錠劑饋給器基部28‧‧‧支持構件28a‧‧‧凸部(滑動卡合部)30‧‧‧保持機構31‧‧‧落下錠劑導引構件32‧‧‧錠劑落下路徑62‧‧‧凹部(滑動卡合部)40‧‧‧切斷機構41‧‧‧前刃(相向刃)43‧‧‧前刃進退構件51‧‧‧蓋子52‧‧‧鎖扣53‧‧‧鉸鏈54‧‧‧開口60‧‧‧拆卸器(刀刃更換工具)61‧‧‧工具本體部64‧‧‧刀刃保持部
