以下、本発明の発送書類区分けシステム200とシート冊子類送給装置100の一実施形態を、図1~図9、図21に基づいて説明する。図1及び図3に示すように、本実施形態のシート冊子類送給装置100は、ベースフレーム90に対して種々の部品を組み付けてなる。ベースフレーム90は装置台101の上面に固定されたベースプレート91と、ベースプレート91の両側部に備えられて水平方向(図1~図3の紙面と直交する方向)で対向したサイドプレート92,92と、サイドプレート92の後端部を連結したカバープレート93(図2参照)とを備える。カバープレート93はベースフレーム90の前方(図2の右側)に向かって下るように水平面に対して傾斜して取り付けられている。なお、図1~図3には一方のサイドプレート92のみが示されている。
本実施形態は図10に示されており、直動支持機構10Aの構造が第1実施形態とは異なる。この実施形態の直動支持機構10Aの固定ベース162は、第1実施形態の固定ベース11と同様に部品取付部80(図3参照)を介して積層載置部70の前面に固定されている(以下、第3~第9の実施形態における「固定ベース」も同様である)。その固定ベース162には、1対のシャフト挿通孔162A,162Aが上下方向に貫通形成され、それらシャフト挿通孔162A,162Aに1対の可動シャフト163,163が挿通されている。そして、1対の可動シャフト163,163の上端部間が上側バネ当接板160(本発明に係る「上側加圧部材」に相当する)によって連結される一方、下端部間が下側バネ当接板161(本発明に係る「下側加圧部材」に相当する)によって連結されている。
なお、本実施形態においては、例えば、固定ベース162のうち上側バネ当接板160との対向面に雌螺子孔を形成して、その雌螺子孔に本発明に係る「下端ストッパ部」兼「下端ストッパ移動操作部」としての下端ストッパ用ボルトを螺合してもよい。これにより、第1実施形態と同様に、可動ベース29Mが下方に移動したときに上側バネ当接板160が下端ストッパ用ボルトに当接して、その当接位置より下方に可動ベース29Mが移動することを禁止する構成としてもよい。また、例えば、固定ベース162のうち下側バネ当接板161との対向面に雌螺子孔を形成して、その雌螺子孔に本発明に係る「上端ストッパ部」兼「上端ストッパ移動操作部」としての上端ストッパ用ボルトを螺合してもよい。これにより、第1実施形態と同様に、可動ベース29Mが上方に移動したときに下側バネ当接板161が上端ストッパ用ボルトに当接して、その当接位置より上方に可動ベース29Mが移動することを禁止する構成としてもよい。
本実施形態は図11に示されており、直動支持機構10Bの構造が第1及び第2の実施形態とは異なる。この実施形態の直動支持機構10Bの固定ベース11Pには、上下方向で対向した上側シャフト支持壁150と下側シャフト支持壁151とが設けられている。上側シャフト支持壁150には、上下方向に雌螺旋孔151Bが上下方向に貫通形成されている。その雌螺旋孔151Bに螺合された調整ナット152によって上側シャフト支持壁150の一部が構成され、調整ナット152と雌螺旋孔151Bとによって本発明に係る変形量調節機構152Kが構成されている。
本実施形態は図12に示されており、直動支持機構10Cの構造が第1~第3の実施形態とは異なる。この実施形態の直動支持機構10Cの固定ベース11Sには、前方(部品取付部80(図3参照)から離れる側)に向かって突出した上端弾性体受け部153が備えられ、その上端弾性体受け部153には、上下方向に貫通孔153Aが貫通形成されている。また、固定ベース11Sの上面にはボルト支持プレート156が固定されており、そのボルト支持プレート156には、貫通孔153Aの同軸上に上端弾性体受け部153より小径の貫通孔156Aが形成されている。そのボルト支持プレート156に調整螺旋158が回転可能かつ上下動不能に支持されている。具体的には、調整螺旋158は上端部に摘み操作部158Sを備えると共に、上端寄り位置に係合溝を備えている。また、摘み操作部158Sをボルト支持プレート156の上面における貫通孔156Aの縁部に当接させた状態で係合溝にEリング158Rを係合してボルト支持プレート156の下面における貫通孔156Aの縁部に宛うことで、調整螺旋158がボルト支持プレート156に回転可能かつ上下動不能に支持されている。
本実施形態は図13に示されており、直動支持機構10Dの構造が第1~第4の実施形態とは異なる。この実施形態の直動支持機構10Dの固定ベース165には、上下方向に雌螺旋孔165Nが上下方向に貫通形成されている。そして、雌螺旋孔165Nに下方から調整ボルト166が螺合されて、その調整ボルト166が固定ベース165の一部を構成している。また、雌螺旋孔165Nと調整ボルト166とによって本発明に係る変形量調節機構165Kが構成されている。
本実施形態は図14に示されており、直動支持機構10Eは、第5実施形態の固定ベース165の雌螺旋孔165Nに対して上方から調整ボルト166を螺合した点が前記第5実施形態と異なる。そして、調整ボルト166と雌螺旋孔165Nとによって、本発明に係る変形量調節機構165Kが構成されている。また、可動シャフト169のうち固定ベース165より下側部分に可動当接部材171Vが溶接固定され、その可動当接部材171Vのフランジ部171Fと固定ベース165との間に本発明の「サブ弾性体」としての複数のサブ引張コイルバネ174が引張状態に取り付けられると共に、本発明の「メイン弾性体」としてのメイン圧縮コイルバネ173が圧縮状態になって可動シャフト169に挿通されている。
本実施形態は図15に示されており、直動支持機構10Fの構造が第1~第6の実施形態とは異なる。この実施形態の直動支持機構10Fの固定ベース11Pには、上下方向で対向した上側受圧壁179と下側受圧壁180とが設けられている。上側受圧壁179には、上下方向に雌螺旋孔179Nが上下方向に貫通形成されている。その雌螺旋孔179Nに螺合された調整ナット177によって上側受圧壁179の一部が構成され、調整ナット177と雌螺旋孔179Nとによって本発明に係る変形量調節機構177Kが構成されている。
本実施形態は図16に示されており、直動支持機構10Gは、第7実施形態のメイン圧縮コイルバネ25T、サブ圧縮コイルバネ26Tの代わりに、メイン引張コイルバネ25V、サブ引張コイルバネ26Vを備えた構造になっている。具体的には、メイン引張コイルバネ25Vは、回動レバー部178A及び下側支持壁185に両端部を係止された状態で引張状態に取り付けられている。一方、サブ引張コイルバネ26Vは、回動レバー部178A及び上側支持壁184に両端部を係止された状態で引張状態に取り付けられている。また、上側支持壁184を上下方向に貫通した雌螺旋孔184Nには、調整ナット181が螺合されている。調整ナット181は、中心部に貫通孔181Hを有し、そこに芯部材182が回転可能に収容されている。そして、サブ引張コイルバネ26Vは、芯部材182及び回動レバー部178Aに両端部を係止された状態で引張状態に取り付けられている。そして、調整ナット181と雌螺旋孔184Nとからなる変形量調節機構181Kの操作による書類S,Bの厚さに応じた調節が可能になっている。
なお、本実施形態においても第7の実施形態と同様に、例えば、下側支持壁185のうち回動レバー部178Aとの対向面に雌螺子孔を形成して、その雌螺子孔に本発明に係る「下端ストッパ部」兼「下端ストッパ移動操作部」としての下端ストッパ用ボルトを螺合してもよいし、上側支持壁184のうち回動レバー部178Aとの対向面に雌螺子孔を形成して、その雌螺子孔に本発明に係る「上端ストッパ部」兼「上端ストッパ移動操作部」としての下端ストッパ用ボルトを螺合してもよい。
本実施形態は図17及び図18に示されており、直動支持機構10Hの構造が第1~第8の実施形態とは異なる。図18に示すように、この実施形態の直動支持機構10Hにおける固定ベース199の両側面からは1対の回動支持ピン187A,187Bが同軸上に配置されて相反する方向に突出している。そして、それら1対の回動支持ピン187A,187Bに、可動ベース29Hに備えた1対の回動レバー部186A,186Bが回動可能に支持されて水平方向に延びている。また、1対の回動レバー部186A,186Bの先端部の間は水平連絡部材29Wによって連結され、その水平連絡部材29Wから垂下された連結部161Bの下端部に重送規制部材30が固定されている。

本発明の技術的範囲には属しないが、図19に示した直動支持機構10Jによって本発明の第1実施形態と同様の効果を奏する。即ち、図19に示した直動支持機構10Jは、サブ圧縮コイルバネ26を有さず、メイン圧縮コイルバネ25の弾発力によって押圧用ワッシャ23Bがヘッドキャップ14の上面に当接している。また、この直動支持機構10Jは、前記第1実施形態の固定ベース11の固定ベース本体11Hから結合突壁300を後方に突出させた構造の中間支持ベース11Wを備えている。そして、積層載置部70(図2参照)から固定突壁301が前方に延び、その固定突壁301の上方に結合突壁300が配置されている。また、結合突壁300には、上下方向に1対の螺旋挿通孔304,304が貫通形成される一方、固定突壁301には、1対の雌螺旋孔302,302が貫通形成され、1対の螺旋挿通孔304,304に上方から挿通したボルト306,306が雌螺旋孔302,302に螺合されている。また、結合突壁300には、1対の螺旋挿通孔304,304の間に雌螺旋孔305が貫通形成され、そこに上方から対抗ボルト307が螺合して結合突壁300を貫通し、その対抗ボルト307の下端部が雌螺旋孔302の上面に突き当てられている。この構造により、中間支持ベース11Wのうち可動シャフト20を直動可能に支持した部分全体が積層載置部70に対して上下動可能な構成になっている。
