す。 Fig. 1 shows an overview of the reading section of a facsimile machine.
is a light receiving element. The medium guide and hold mechanism 3 includes a movable guide plate 6 and a fixed guide plate 7. The movable guide plate 6 is fixed between the rollers 1 and 2 to a support member (not shown) that supports the rollers 1 and 2 and is swingable about point O in FIG. 2 as a fulcrum. The fixed guide plate 7 is
It is fixedly provided between rollers 1' and 2', and has a slit 8 formed in its center. When the device is in operation, the movable guide plate 6 faces the fixed guide plate 7 with a gap t 1 in between, as shown in FIG. The original (medium) 30 sent to the reading unit in such a state is
It is sent to the right side in FIG. 1 by rollers 1 and 1', and is guided by guide portions 6a and 7a integrally formed at the ends of the medium entry side of each guide plate 6 and 7 with an outward slope. It enters between the guide plates 6 and 7, and information is read at the slit 8. Information reading is performed by emitting reflected light from a light source such as a fluorescent lamp (not shown) provided at the bottom of the fixed guide plate 7, passing through the slit 8, and illuminating the information on the document 30. The reflected light is passed through the lens 4 and received by the light receiving element 5. It is done as follows. The document 30 is fed between the guide plates 6 and 7 while reading information in this way, and when its front end reaches between the rollers 2 and 2', it is continued to be fed to the right by the rollers 2 and 2'. is discharged. The reason why the movable guide plate 6 is swingably provided as described above is so that when a document jam occurs between the guide plates 6 and 7, it can be easily removed. In such a case, the movable guide plate 6 is swung to the open position as shown in FIG. 2, and the jammed original is taken out.
このような読取部においては、読取られる媒体
の厚さは一般に一定ではなく、そのため両案内板
６，７間の間隙t1を最も厚い媒体を安定して送ら

媒体ジヤムが発生し易く、上述のように可動固定
６が開放可能に設けられてもジヤム紙取り出しは
面倒である。 In such a reading section, the thickness of the medium to be read is generally not constant, and therefore the gap t1 between the guide plates 6 and 7 must be set so that the thickest medium can be stably fed. In this case, a medium jam is likely to occur between the guide plates 6 and 7 when transporting a thin and weak medium, and even if the movable fixing 6 is releasably provided as described above, it is troublesome to take out the jammed paper. .

This invention is intended to solve the above problems.
It is an object of the present invention to provide a medium guiding and holding mechanism that can stably transport media of various thicknesses without causing jams.
次に第３図乃至第６図に関連して本考案の実施
例を説明する。 Next, embodiments of the present invention will be described with reference to FIGS. 3 to 6.

る。 FIG. 3 is a front view showing an outline of a reading section to which the present invention is applied, and FIG. 4 is a sectional view taken along the line AA in FIG.
図中、１１は媒体案内保持機構で、固定案内板
１２と、可動固定板１３とよりなる。 In the figure, reference numeral 11 denotes a medium guiding and holding mechanism, which is composed of a fixed guide plate 12 and a movable fixed plate 13.
固定案内板１２の内側の媒体通路より外側の両
端にはそれぞれ厚さt2のスペーサ１４，１４が取
付けられている。 Spacers 14, 14 each having a thickness of t2 are attached to both ends of the fixed guide plate 12 on the outside of the medium passage.
可動案内板１３は、固定案内板１２に向けて進
退自在に設けられ、支持部材１５との間に設けら

いる。 The movable guide plate 13 is provided so as to be able to move forward and backward toward the fixed guide plate 12, and is supported by springs 16, 16 provided between the movable guide plate 13 and the fixed guide plate 12.
It is urged toward and abuts on the spacers 14, 14.

である。 The thickness t 2 of the spacer 14 is selected to be larger than the thickness of the thin document by an appropriate amount. Therefore, when a thin document with weak stiffness is sent, the movable guide plate 13 remains in contact with the spacers 14, 14, as shown in FIG. It is guided and held without jamming. Further, when a thick document that is thicker than the spacer 14 is sent, the document 30 is first guided by the guide portions 12a and 13a of each guide plate, and the movable guide plate 13 is moved backward against the biasing force of the springs 16 and 16. As shown in Figure 6, both guide plates 1
It enters between 2 and 13 and is held. Therefore, it is possible to stably guide and hold documents of various thicknesses without jamming. In the figure, 17 is a slit.

案内板１３を開放することが可能で、保守、点検
に便利である。 Note that if the support member 15 is provided to be swingable and the rollers 1 and 2 are supported by the support member 15, the movable guide plate 13 can be opened by swinging the support member 15 as in the conventional case. It is convenient for maintenance and inspection.
上述の説明ではスペーサ１４を固定案内板１２
に取付ける例について述べたが、スペーサ１４を
可動案内板１３に取付けるようにしても良い。 In the above explanation, the spacer 14 is replaced by the fixed guide plate 12.
Although an example in which the spacer 14 is attached to the movable guide plate 13 has been described, it is also possible to attach the spacer 14 to the movable guide plate 13.

When a weak, thick medium is fed, the movable guide plate is moved backward by the medium, and the medium is fed and held in close contact with each guide plate, so that media of various thicknesses can be stably handled. It is possible to transport and hold the
