おｍ■述したと四−カ所には同一符号が付しである。SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a paper transport unit including a paper transport unit holding plate spring disposed on a transport board, and a paper transport unit rotatably supported on a shaft and mounted on the paper transport unit holding plate spring. A leaf spring receiving member comprising a first abutting member that makes sliding contact and a second abutting member that makes contact with the conveyance board of the paper conveyance unit within the elastic deformation limit of the paper conveyance unit holding leaf spring. DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the drawings. It should be noted that the same reference numerals are given to the four places mentioned above.

基板７の折曲部２０と当接する寸法に形成されている。3, 4, and 5 show enlarged cross-sectional views of essential parts for detailed explanation of the present invention, and in the figures, reference numeral 20 indicates a bent portion formed on the conveying substrate 7 of the paper conveying unit 3. , 21 is a contact member formed integrally with the leaf spring receiving member 19, and whose tip is brought into contact with the above-mentioned bent portion 2o. This contact member 21 is a paper conveying unit holding plate spring 1o.
It is formed to have a dimension that is within the elastic deformation limit of , that is, before permanent deformation occurs, it comes into contact with the bending portion 20 of the transfer substrate 7.
