3 has a horizontal portion 39 extending substantially horizontally,
A guide member 41 which is a resin molded product is rotatably connected to the horizontal portion 39. Both ends of the two paper feed driven rollers 17 are rotatably supported at the distal end 43 of the guide member 41. A central portion 49 of the torsion coil spring 47 is held by a spring locking portion 45 formed on the horizontal portion 39, and one end 5 located on the front side of the torsion coil spring 47.
1 is fixed to the upper surface of the distal end portion 43 of the guide member 41.

The locking action end 54 is locked on the support portion 57 located at the base end of the horizontal portion 39 while penetrating the notch portion 55 formed in the horizontal portion 39. Since both ends of the torsion coil spring 47 are supported by the upper surface of the distal end portion 43 and the support portion 57 in a state where the two ends of the torsion coil spring 47 are bent upward from the free state of the spring, one end 51 of the spring is returned by the return force of the torsion coil spring 47. The paper feed driven roller 17 is pressed against the paper feed drive roller 15 as a result. A plurality of paper feed driven rollers 17 having the same structure as described above are provided along the paper feed drive roller 15.

い。As shown in FIG. 4, the other end 53 of the torsion coil spring 47 extends rearward at an angle nearly horizontal, and as a result, the downward force component F 1 (of the main frame 33) A resultant force F of a force component in the extending direction) and a force component F 2 in the horizontal direction (a force component in a direction in which the main frame 33 is bent) acts. Although the direction of the resultant force F is are longer shown in order to clearly show the horizontal force component F 2 is substantially are parallel direction (i.e., vertical direction) (FIG. The direction of extension of the main frame 33, the actual is the horizontal force components F 2, small that the resultant force F is substantially perpendicular to). Thus, since the other end 53 is acting horizontal force component F 2 of the force and extremely small in the support portion 57, all of the torsion coil spring 47 to be more provided along the paper feed driving roller 15 the main frame 33 also align the horizontal force component F 2 does not flex rearward.

う従来の問題が解消される。By adopting such a configuration, the flap holding member 71 also moves up and down as the guide member 41 moves up and down as the paper thickness of the envelope P changes. The interval between the paper feed drive roller 15 and the paper feed drive roller 15 can be always maintained to such an extent that the flap Q of the envelope P can pass through. Therefore, the flap Q of the envelope P
Is clogged beneath the flap holding member 71.

That is, the flap holding member 71 is provided separately from the guide member 41, and the flap holding member 71 is provided with, for example, a rotation mechanism similar to that of the above-described guide member 41, and applies a downward biasing force that does not allow the flap to float. Alternatively, the member 71 may be provided alone. When such a structure is adopted, the downward urging force of the main body portion and the flap portion of the envelope can be individually adjusted according to the paper thickness and the lifting force.
