【Example】

 Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows an embodiment of a recording paper feeding apparatus according to the present invention applied to a facsimile apparatus 1. In this embodiment, the paper feed cassette 2 as shown in FIG. 2 is used. As shown in FIG. 3, the paper feeding cassette 2 has a handle 204 formed of a concave portion at the center of the front side surface 201, the left side surface 202 and the right side surface 203 of the cassette body 200, and the recording shown in FIG. A cover 208 is detachably attached above the paper storage unit 207.

Further, as shown in FIG. 2, a push-up plate 210 biased upward by a spring 209 is arranged at the right end portion of the cassette main body 200, and as shown in FIG. A rectangular engaging hole 212 is formed through the central portion of the bottom plate 211 of the main body 200.

On the other hand, as shown in FIG. 4, cassette insertion ports 105, 106 and 107 are formed on the front side surface 102, the left side surface 103 and the right side surface 104 of the casing 101 of the facsimile apparatus 1, respectively. An engagement body 108 is arranged at the bottom of the casing 101.

As shown in FIG. 5, the engaging body 108 is vertically movably fitted to a guide frame 110 formed on the bottom plate 109 of the housing 101, and is upwardly moved by a spring 111 shown in FIG. Being energized. Therefore, it is normally pushed up to the position shown by the biasing force of the spring 111, and at this time, the floor plates 112 arranged in parallel above the bottom plate 109 are in contact with the overhanging portions 108a at the lower left and right sides thereof, and An upper portion of the floor plate 112 is exposed from an upper surface of the floor plate 112 through an opening 113 formed in the hole 112.

Next, the operation of this embodiment will be described. As shown in FIG. 4, the paper feed cassette 2 is inserted into the housing 101 through any of the cassette insertion ports 105, 106, and 107. It should be noted that the insertion attitude of the cassette 2 with respect to the housing 101 is the same regardless of which cassette insertion port is used.

The inserted paper feed cassette 2 has columnar parts 115 to 117 shown in FIG. 7 formed on the sides of the floor plate 112, the top plate 114 shown in FIG. 1 and the cassette insertion ports 105 to 107. It is moved toward the central portion of the housing 101 while being guided by.

While the paper feed cassette 2 is moving, the paper feed cassette 2 contacts the upper tapered surface 108 b of the engagement body 108 shown in FIG. 5, and thereafter, the cassette 2 moves the engagement body 108 against the spring 111. Move while lowering. Then, when the sheet feeding cassette 2 is moved to a predetermined sheet feeding position and the engaging hole 212 of the cassette 2 is positioned directly above the engaging member 108, the engaging member 108 is projected by the biasing force of the spring 111, The engaging body 108 is fitted in the engaging hole 212 of the cassette 2 as indicated by the one-dot chain line in FIG. As a result, the paper feed cassette 2 is positioned at the paper feed position and holds that position.

Here, when the facsimile device 1 is in the receiving state, the movable guide member 118 shown in FIG. 1 is rotated by an actuator such as a solenoid to a position indicated by a chain line, and thereafter, a feeding roller 119 having a semicircular cross section. Is rotated and the recording paper (not shown) in the paper feed cassette 2 is fed to the right.

The fed-out recording paper passes through the guide member 118, is then conveyed to the recording head 122 by the conveyance rollers 120 and 121, and then is superposed on the ink film 123. Then, it is conveyed while being pressed against the recording head 122 by the platen roller 124, during which the received information is recorded.

The recording paper for which recording has been completed is discharged onto the tray 126 through the passage 125. Further, when the reception is completed, the movable guide member 118 is retracted to the position shown by the solid line, and the feeding roller 119 is placed in the posture shown in the figure. Therefore, the movable guide member 118 and the roller 119 are moved to the sheet feeding cassette 2 It does not hinder the operation of taking in and out.

When the sheet feeding cassette 2 set at the sheet feeding position is pulled toward one of the cassette insertion ports, the edge of the engaging hole 212 of the cassette 2 is attached to the upper tapered surface 108 b of the engaging body 108. Abutment is made and the engaging body 108 is lowered. Therefore, the engagement between the engagement hole 212 and the engagement body 108 is released, whereby the sheet feeding cassette 2 can be moved to the desired cassette insertion port and taken out.

The handle 204 shown in FIG. 3 is used for the operation of taking in and out the paper feed cassette 2. Further, at the time of transmission by the facsimile apparatus 1, an original document (not shown) placed on the tray 127 is carried into the reading unit 128, and the recorded content of the original document is read there. Then, the read original is discharged onto the tray 129.

In the above-described embodiment, the cassette insertion opening is provided on the front side surface 102, the left side surface 103 and the right side surface 104 of the housing 101, but it is also possible to provide a cassette insertion opening on the back surface of the housing 101. is there. Further, although the above embodiment is applied to the facsimile machine, the present invention can be naturally applied to other devices such as a copying machine which requires the supply of recording paper.
