あり、装置が大きくなる等の不都合がある。<Prior Art> Conventionally, various devices for gripping and conveying sheet materials have been provided in devices such as copying machines and printing machines. It is difficult to grip the sheet material with uniform force over the entire gripping part,
There is a high risk that the gripped sheet material will fall during transportation or meander due to external resistance, and if the gripping force is increased to prevent this, the drive device must be larger and the gripping section must be larger. There are disadvantages such as a shortened lifespan. In addition, in a device in which an elastic member is provided in the gripping part in order to solve these problems, it is fine if the sheet material to be gripped is small, but if the sheet material is large, it is necessary to grip the sheet material uniformly over the entire gripping part. As a countermeasure to this problem, it is necessary to increase the thickness of the elastic member or increase the gripping force, which causes disadvantages such as an increase in the size of the device.

It is an object of the present invention to provide a small and highly reliable document conveying device that can evenly grip the entire end portion (gripping portion) of a sheet material with a weak driving force.

0-3 changes from the press-contact state to the separated state at the grip plate separation member 101 due to the action of the solenoid 23 (see FIGS. 1 and 2b). Then, when the entire document conveying device is moved by means not shown, the sensor (composed of 18 and 19) for detecting the edge of the document P detects the edge of the document P, and at the same time, the solenoid 23 is turned off.
The upper document gripping plate 9 and the plurality of lower gripping plates 10-1 , 10-2 , and 10-3 are closed by the action of a plurality of spring members 71 stretched between them. In this state, the edges of the document P are held by the document gripping plates 9 and 10-1 , 1
Since it is sandwiched between the elastic friction members 61 and 62 provided at the tips of the grippers 0-2 and 10-3 , it is gripped with uniform force over the entire gripping portion. That is, the lower gripping plates 10-1 , 10-2 , 10-3
Since the upper document holding plate 9 can be adjusted individually using the spring member 71, the document can be held uniformly across the entire width of the document. In particular, by dividing the documents into individual documents, the document can be held uniformly regardless of the width of the document. As described above, the original holding plates 9 and 10-1 , 10-2 , 10-
The document P, which is held between the grippers 3 and 3 with a uniform force over the entire gripping section, is conveyed to the target position. After the desired operation is completed, the document gripping plates 9 and 1
0-1 , 10-2 , and 10-3 are opened by the action of the solenoid 23, the original P is ejected, and the operation moves on to conveying the next original (not shown).

を行える。<Effects> As explained above, according to the document conveying device of the present invention, the leading edge of the document can be held between one gripping plate that is integrally formed and the other gripping plates that are individually divided. Because of this, the gripping portion can be held uniformly over the entire width of the document, and stable document conveyance can be achieved.
