Description
【０００１】[0001]
本考案は、プリンタ、複写機、原稿読取装置等の事務機器に、印字用紙や原稿 等の紙葉を供給する給紙装置に関する。 The present invention relates to a paper feeding device that supplies paper sheets such as printing paper and originals to office equipment such as printers, copiers, and document reading devices.
【０００２】[0002]
この種の給紙装置においては、事務機器に供給する紙葉の斜行を防止するため に種々の考案がなされている。その一例を図３及び図４に基づいて説明する。１ は紙葉が載置される紙葉載置面で、この紙葉載置面１の両側には紙葉の両側を案 内するサイドガイド２，３が対向配置されている。右方のサイドガイド２は固定 されているが、左方のサイドガイド３は紙葉の幅方向Ｂに沿って変位自在に保持 されている。また、紙葉載置面１の左側には多数の係止歯４が紙葉の幅方向Ｂに 沿って鋸歯状に配列されて一体に形成されている。そして、左方のサイドガイド ３には弾性的に屈撓する弾性片５が形成されている。図４に示すように、この弾 性片５の先端には係止歯４に噛合される係止爪６が形成されている。 In this type of paper feeding device, various devices have been devised to prevent the skew of the paper sheet supplied to the office equipment. One example thereof will be described with reference to FIGS. 3 and 4. Reference numeral 1 denotes a paper sheet placement surface on which a paper sheet is placed. On both sides of the paper sheet placement surface 1, side guides 2 and 3 are provided so as to face both sides of the paper sheet. The right side guide 2 is fixed, but the left side guide 3 is displaceably held along the width direction B of the sheet. On the left side of the paper sheet stacking surface 1, a large number of locking teeth 4 are arranged integrally in a sawtooth shape along the width direction B of the paper sheet. The left side guide 3 is formed with an elastic piece 5 that elastically bends. As shown in FIG. 4, a locking claw 6 that meshes with the locking tooth 4 is formed at the tip of the elastic piece 5.
【０００３】 したがって、紙葉のサイズに応じてサイドガイド３を紙葉の幅方向Ｂに沿って 移動させたときに、係止爪６を任意の係止歯４に噛合させることによりサイドガ イド３の動きが固定される。Therefore, when the side guide 3 is moved along the width direction B of the paper sheet in accordance with the size of the paper sheet, the locking claw 6 is engaged with the arbitrary locking tooth 4 to cause the side guide 3 to move. The movement of is fixed.
【０００４】[0004]
サイドガイド３の動きを確実に固定するためには、係止歯４と係止爪６とを一 定の深さをもって噛合させる必要があるので、係止歯４の配列ピッチを１ｍｍ以 下にすることは望ましくない。したがって、紙葉の幅にはバラツキがあるため、 紙葉の幅にサイドガイド２，３の対向間隔を一致させることが困難な場合がある 。この結果、僅かのスキューについては防止することができない。 In order to securely fix the movement of the side guide 3, it is necessary to engage the locking teeth 4 and the locking claws 6 with a certain depth. Therefore, the arrangement pitch of the locking teeth 4 should be 1 mm or less. Is not desirable. Therefore, since the width of the paper sheet varies, it may be difficult to match the facing distance between the side guides 2 and 3 with the width of the paper sheet. As a result, a slight skew cannot be prevented.

【課題を解決するための手段】 本考案は、紙葉が載置される紙葉載置面と、この紙葉載置面の両側に対向配置 されて少なくとも一方が前記紙葉の幅方向に沿って変位自在に保持された左右一 対のサイドガイドと、前記紙葉載置面に前記紙葉の幅方向に沿って鋸歯状に配列 された多数の係止歯と、前記紙葉の幅方向に沿って変位される前記サイドガイド に前記係止歯の配列ピッチの複数分の１の配列ピッチをもって形成されて前記係 止歯に噛合される複数の係止爪とにより構成した。Means for Solving the Problems The present invention is directed to a paper sheet placing surface on which a paper sheet is placed, and at least one of the paper sheet placing surfaces facing each other on both sides of the paper sheet placing surface in the width direction of the paper sheet. A pair of left and right side guides that are displaceably held along the paper sheet, a plurality of locking teeth arranged on the paper sheet placement surface in a sawtooth shape along the width direction of the paper sheet, and the width of the paper sheet. The side guides are displaced along the direction, and the side guides are formed with a plurality of engaging claws that are formed with an arrangement pitch that is a multiple of the arrangement pitch of the engaging teeth and that are engaged with the engaging teeth.
【０００６】[0006]
サイドガイドを紙葉の幅方向に沿って変位させ、複数の係止爪の何れか一つを 任意の係止歯に噛合させることにより、係止歯の配列ピッチの複数分の１の間隔 でサイドガイドの対向間隔を微調整することが可能となる。 By displacing the side guide along the width direction of the paper sheet and engaging any one of the plurality of locking claws with an arbitrary locking tooth, at intervals of a multiple of the locking tooth arrangement pitch. It is possible to finely adjust the facing interval of the side guides.
【０００７】[0007]
本考案の一実施例を図１及び図２に基づいて説明する。図３及び図４を参照し て説明した従来例の構造と同一構造の部分については同一符号を用い説明も省略 する。紙葉載置面１の両側で対向するサイドガイド２，３のうち、左方のサイド ガイド３は紙葉の幅方向Ｂに沿って変位自在に保持されている。その保持手段と しては、例えば、サイドガイド３における紙葉載置面１に対する摺動面３ａの下 面に複数の鍔付きピンを立設し、これらの鍔付きピンが摺動自在に嵌合される長 孔を紙葉の幅方向Ｂに沿わせて紙葉載置面１に形成する構造が挙げられるが、他 の方法によりサイドガイド３を変位させてもよい。 An embodiment of the present invention will be described with reference to FIGS. Parts having the same structure as the structure of the conventional example described with reference to FIGS. 3 and 4 are denoted by the same reference numerals, and description thereof will be omitted. Among the side guides 2 and 3 facing each other on both sides of the paper sheet mounting surface 1, the left side guide 3 is displaceably held along the width direction B of the paper sheet. As the holding means, for example, a plurality of flanged pins are erected on the lower surface of the sliding surface 3a of the side guide 3 with respect to the paper sheet mounting surface 1, and these flanged pins are slidably fitted. There is a structure in which the combined long holes are formed on the paper sheet placement surface 1 along the width direction B of the paper sheet, but the side guide 3 may be displaced by another method.
【０００８】 そして、サイドガイド３の摺動面３ａには二つの弾性片５，７が一体に形成さ れ、これらの弾性片５，７の先端付近には係止歯４に噛合される係止爪６，８が 一体に形成されている。図２（ａ）は一方の係止爪６の位置を示し、図２（ｂ） は他方の係止爪８の位置を示すものであるが、これらの係止爪６，８の紙葉の幅 方向Ｂに沿う配列ピッチは、係止歯４の配列ピッチ（１ｍｍ）の２分の１の０． ５ｍｍに定められている。Two elastic pieces 5 and 7 are integrally formed on the sliding surface 3a of the side guide 3, and the engaging teeth 4 are engaged with the elastic teeth 5 and 7 near the tips thereof. The pawls 6 and 8 are integrally formed. FIG. 2A shows the position of one of the locking claws 6 and FIG. 2B shows the position of the other locking claw 8. The arrangement pitch along the width direction B is half the arrangement pitch (1 mm) of the locking teeth 4 and is 0. It is set to 5 mm.
【０００９】 このような構成において、サイドガイド３を紙葉の幅方向Ｂに沿って変位させ るが、係止爪６，８の配列ピッチが係止歯４の配列ピッチの２分の１の寸法をも ってずらされているため、図２（ａ）に示すように、一方の係止爪６を係止歯４ に噛合させたときは、図２（ｂ）に示すように、他方の係止爪８は係止歯４に噛 合しない。逆に、他方の係止爪８を係止歯４に噛合させたときは、一方の係止爪 ６は係止歯４に噛合しない。したがって、複数の係止爪６，８の何れか一つを任 意の係止歯４に噛合させることにより、０．５ｍｍ間隔でサイドガイド２，３の 対向間隔を微調整することができる。これにより、紙葉の幅方向Ｂの遊びを小さ くし、スキューの発生を良好に防止することができる。In such a configuration, the side guide 3 is displaced along the width direction B of the paper sheet, but the arrangement pitch of the locking claws 6 and 8 is half the arrangement pitch of the locking teeth 4. Since they are displaced with respect to each other, when one of the locking claws 6 is engaged with the locking tooth 4 as shown in FIG. 2 (a), the other as shown in FIG. 2 (b). The locking claw 8 of does not mesh with the locking tooth 4. Conversely, when the other locking claw 8 is engaged with the locking tooth 4, the one locking claw 6 does not mesh with the locking tooth 4. Therefore, by engaging any one of the plurality of locking claws 6 and 8 with the desired locking tooth 4, the facing distance between the side guides 2 and 3 can be finely adjusted at 0.5 mm intervals. As a result, the play in the width direction B of the paper sheet can be reduced, and the skew can be effectively prevented.
【００１０】 なお、係止爪の数を３個以上のｎとし、これらの係止爪の紙葉の幅方向Ｂに沿 う配列ピッチを係止歯４の配列ピッチのｎ分の１に定めることにより、さらにサ イドガイド２，３の対向間隔を微調整することができる。It should be noted that the number of the locking claws is 3 or more, and the array pitch of these locking claws along the width direction B of the paper sheet is set to 1 / n of the array pitch of the locking teeth 4. As a result, the facing distance between the side guides 2 and 3 can be further finely adjusted.
【００１１】[0011]
本考案は、上述のように、左右一対のサイドガイドが設けられた紙葉載置面に 多数の係止歯を紙葉の幅方向に沿って鋸歯状に形成し、紙葉の幅方向に沿って変 位されるサイドガイドに係止歯の配列ピッチの複数分の１の配列ピッチをもって 係止歯に噛合される複数の係止爪を形成したので、サイドガイドを紙葉の幅方向 に沿って変位させ、複数の係止爪の何れか一つを任意の係止歯に噛合させること により、係止歯の配列ピッチの複数分の１の間隔でサイドガイドの対向間隔を微 調整することができ、したがって、紙葉の幅方向の動きを規制してスキューの発 生を良好に防止することができる。 According to the present invention, as described above, a large number of locking teeth are formed in a serrated shape along the width direction of a paper sheet on the paper sheet mounting surface provided with a pair of left and right side guides, and Since the side guides displaced along the side guides are formed with a plurality of locking claws that mesh with the locking teeth at an arrangement pitch that is a multiple of the arrangement pitch of the locking teeth, the side guides are arranged in the width direction of the paper sheet. By displacing along one of the locking pawls and engaging one of the locking pawls with an arbitrary locking tooth, the facing interval of the side guides is finely adjusted at intervals of a multiple of the array pitch of the locking teeth. Therefore, the movement of the paper sheet in the width direction can be regulated, and the occurrence of skew can be favorably prevented.
