するのである。 7 and 8 both show a conventional paper feed cassette C. FIG. That is, the structure shown in FIG. 7 has a width guide 2 and a length guide 3 fixedly installed in the cassette body 1 to regulate and position the paper P in the vertical and horizontal directions. Therefore, detection protrusions 4 of different shapes are provided on the side surface of the main body 1. When the paper feed cassette C having such a structure is inserted into, for example, the copying machine main body 7 in the insertion direction shown by the arrow A, the detection protrusion 4 comes into contact with the detectors 5 and 6, such as micro switches, provided on the main body 7 side. Based on the detection signals generated by the operation of the detectors 5 and 6, the machine body 7 recognizes the type of paper feed cassette C, that is, the paper size.
したがつて、こうした給紙カセツトＣが用紙サ
イズの種類数だけ用意されるのであり、これら全
ての保管には大きなスペースを要して装置全体の
嵩容積が増大する原因となつている。 Therefore, such paper feed cassettes C are prepared for the number of paper sizes, and storing all of these cassettes requires a large space, which causes an increase in the bulk volume of the entire apparatus.
この解消手段として、縦横の巾ガイド２，３を

あるために、制御機構が複雑化する不具合があ
る。 As a means of solving this problem, there is a method in which the vertical and horizontal width guides 2 and 3 are movable in directions orthogonal to each other to accommodate changes in paper size, and the moving position of the width guides 2 and 3 is detected on the machine body 7 side. . However, in this case, since it is necessary to provide a number of detection means corresponding to each movement point of the width guides 2 and 3 on the body 7 side, there is a problem that the control mechanism becomes complicated.
即ち、第８図はかゝる巾ガイド２，３の移動構

切片２ａ，３ａが嵌入して外部に突出している。 That is, FIG. 8 shows a conventional example in which the width guides 2 and 3 are moved. According to this, vertical and horizontal width guides 2 and 3 are guided by guide grooves 1a and 1b provided on the side of the cassette main body 1 and are slidable in the width direction and the length direction of the paper P, respectively. Engagement pieces 2a and 3a of the width guides 2 and 3 are fitted into slits 1c and 1d formed on the main body 1 side in accordance with the sliding direction and protrude to the outside.

4 of ``Legal (8 1/2'' x 14'')''
When adapting to different paper widths, the detection of these paper width dimensions is carried out by three detectors 8, 9, and 10 that are activated by engaging with the engaging section 2a of the width guide 2, and also the paper length dimension. is detected by the engaging section 3 of the width guide 3.
This is done by one detector 11 which is activated by engaging a. Thus, at least four detectors 8, 9, 10, 11 are required.

実施例
以下、本発明の実施例である給紙カセツト構造
について第１図乃至第６図を参照しつつ述べる。
なお、従来例の説明で用いられた符号に共通する
ものは同一又は同種の部材を指すものとする。Embodiment Hereinafter, a paper feed cassette structure according to an embodiment of the present invention will be described with reference to FIGS. 1 to 6.
Note that common symbols used in the description of the conventional example refer to the same or similar members.
第１図において、用紙の巾方向及び長さ方向を
夫々規制する横ガイド２、縦ガイド３が、カセツ
ト本体１の底部に穿たれた案内溝１ａ，１ｂに案
内されて摺動自在である。 In FIG. 1, a horizontal guide 2 and a vertical guide 3, which regulate the width direction and length direction of the paper, respectively, are slidable while being guided by guide grooves 1a and 1b bored in the bottom of the cassette body 1.
縦横のガイド２，３は共に本体１側の案内溝１
ａ，１ｂに嵌合する縦横夫々の摺動片２ｂ，３ｂ
が直角に折曲成形されていて、これら摺動片２
ｂ，３ｂの一部は交差して重なり合つている。 The vertical and horizontal guides 2 and 3 are both in the guide groove 1 on the main body 1 side.
Vertical and horizontal sliding pieces 2b and 3b that fit into a and 1b
are bent at right angles, and these sliding pieces 2
Parts of b and 3b intersect and overlap.
又、摺動片２ｂ，３ｂの各々には、例えば一方
の摺動片２ｂに貫通した３個の検出孔H1，H2，
H3が設けられ、他方の摺動片３ｂにも貫通した
４個の検出孔H4，H5，H6，H7が設けられてい

つて、相対的に交差位置の変化する摺動片２ｂ，
３ｂ同士は、互いに相手の検出孔H1〜H3及びH4
〜H7の幾つかに重なり合い或いは隠蔽し合う仕
組みとなつている。 Further, each of the sliding pieces 2b and 3b has, for example, three detection holes H 1 , H 2 , which penetrate through one sliding piece 2b.
H 3 is provided, and the other sliding piece 3b is also provided with four penetrating detection holes H 4 , H 5 , H 6 , and H 7 . Therefore, as the guides 2 and 3 move vertically and horizontally, the sliding pieces 2b and 3 whose intersecting positions change relative to each other.
3b are the detection holes H 1 to H 3 and H 4 of each other.
~ H7 It is a mechanism that overlaps or hides each other.
一方、カセツト本体１には図中破線にて示され
るホツパプレート１２が設けられていて、この裏
面すなわち上記検出孔H1〜H7に対向する面には
図示せぬ反射板が備わつている。 On the other hand, the cassette body 1 is provided with a hopper plate 12 shown by a broken line in the figure, and a reflection plate (not shown) is provided on the back surface of the hopper plate 12, that is, the surface facing the detection holes H1 to H7 .

１３，１４が設置されている。 On the body 7 side of a copying machine or the like, detection holes H 1 to H 7 are hidden or exposed by the reflection plate of the hopper plate 12 at the intersection of the sliding pieces 2b and 3b.
Two detectors 13 and 14, such as reflective photo sensors, are installed to reflect the overlapping light and detect the reflected light.
したがつて、カセツト本体１側の７個の検出孔
H1〜H7と機体７側の２個の検出器１３，１４と
によつて、第２図乃至第５図で示される４種類の
用紙サイズが、例えば「レター」、「リーガル」、
「A4」および「B5」の如くに予め設定されている
ものが判別されるのである。 Therefore, the seven detection holes on the cassette body 1 side
By using H 1 to H 7 and the two detectors 13 and 14 on the machine body 7 side, the four types of paper sizes shown in FIGS. 2 to 5 are detected, for example, "letter", "legal",
Preset values such as “A 4 ” and “B 5 ” are determined.
即ち、第２図の「レター」サイズの場合は、摺

出孔H3のみではこれを検出しない場合において、
図表第６図の如くに、「レター」サイズの用紙で
あることを機体７側が認識する。 That is, in the case of the "letter" size shown in FIG. 2, by overlapping the sliding pieces 2b and 3b, the sliding piece 2b
If the detection hole H 2 on the side and the detection hole H 5 on the sliding piece 3b side are set to match, one detector 13 will reduce the reflected light from the matching detection holes H 2 and H 5 to 1. In the case where the other detector 14 does not detect this only with the detection hole H3 on the sliding piece 2b side,
As shown in FIG. 6, the machine 7 recognizes that the paper is a "letter" size paper.
同様な設定で、第３図の「リーガル」サイズに
おいては、検出孔H2とH6とを合致せしめ、検出
孔H3とH7とを合致せしめた場合、両検出器１
３，１４は共に対応孔の反射光を夫々検出して、
「リーガル」サイズの用紙であることが判別され
る。 With similar settings, in the "Legal" size shown in Figure 3, if detection holes H 2 and H 6 are matched and detection holes H 3 and H 7 are matched, both detectors 1
3 and 14 detect the reflected light of the corresponding hole, respectively,
It is determined that the paper is of "legal" size.
第４図の「A4」サイズにおいては、合致する
検出孔が全くない場合で、両検出器１３，１４に
よる検出がなされないときである。 In the case of size "A 4 " in FIG. 4, there is no matching detection hole at all, and there is no detection by both detectors 13 and 14.
第５図の「B5」サイズにおいては、検出孔H1
とH4とを合致せしめて、これらを一方の検出器
１４のみが検出する場合である。 For the size “B 5 ” in Fig. 5, the detection hole H 1
This is a case where only one of the detectors 14 detects these by making them coincide with H 4 .
なお、上記した実施例構造においては、用紙サ
イズの認識のみについて説明なされたが、これに
限らず用紙のカセツト本体１における位置の認識
も可能である。 In the structure of the above-described embodiment, only the recognition of the paper size has been described, but the present invention is not limited to this, and recognition of the position of the paper in the cassette body 1 is also possible.
