[0078] 10 picture displayed in the deformation embodiment can replace side guiding element 100 image 5 side guiding element 110 is set on the tray of lead assembly 90 degrees on the replace tray 80 using an ila the tray of the 120. Other structures of the embodiments of the same. The image 10 in order to make the side guiding element 110 the structure is clear and it omits the upper guide piece 5 104 image the image display. Bidentata bo 11# middle of the image in the upper and lower direction 7 and left and right direction of the tray 9 is transmitted 120 130 posture of lower direction of.

[0079] picture 10 the side guiding element 110 has a: 111 side wall of the tray guiding element 91 90 degrees the bottom plate of the upper surface of the 92 of the left and right two end parts protrudes; And two projected from the side wall 112 111 91 to the bottom of the left and right direction 9 middle part of the protruding. Two protrusions 112 the front and back direction 8 is arranged. Through setting two convex 112 it can prevent the tray is 120 degrees on the bottom plate to rotate on 91. Protruded 112 is equal to the utility model claims a projection.

[0080] picture ila the tray is 120 degrees with the back part of the first width is 121 and the front part of the second width of 122. The first width 121 part of the left and right direction on width w2 of a ratio of the second width 122 part of the left and right direction of the width of the width w3 9. Tray is 120 degrees is formed the first width is 121 width w2 of a ratio of the left and right convex part of the 112 the protrusion of the front end of the separating between the distance image is a little narrow 10b l12. Separation distance l12 the utility model claims a first distance an embodiment of.

[0081] picture ioa the protruding 112 is set on following position on the front and back direction of the tray 8 is 120 the first width is 121 the length of the ratio l 9 from the back side of the protrusion the protrusion of the 112 the front end of the second transfer roller pair 54 of the holding position no 6 llo long distance less than the back side of the protrusion the protrusion of the 112 the front end of the first transmission roller to 50 of clamping position of the short distance lll 7. If ioc the display image from printing part 11 the opening of the i picture 19 the inserting of the tray is 120 degrees the back end of the located on the first transmission stick to 50 the second transmission stick to 54 when the tray 120 the first width 121 part of the front end of the through the back side of the protruding 112 between. S * the first part of the width of 121 along the direction towards back 47 the first direction of the direction of the position is: On the tray is 120 degrees the beginning of the second transfer roller pair 54 transmitting time the side guiding element of sliding contact 110 and 120 to start the tray is composed of the first transmission roller to 50 and a second transfer roller pair 54 two transmission time as the side guiding element and the contact position of 110.

[0082] so the deformation in the example embodiments also a pair of left and right side guiding element on the tray 110 120 to the second transfer roller pair 54 before it can prevent the tray is 120 degrees the inclined and the tray is 120 degrees it is composed of the first conveyance roller pair of 50 to be transmitted and it will not make the tray is 120 degrees the transmission resistance. Side guiding element 110 can not be reduced image the recording accuracy is to prevent the tray the inclination of 120. 121 part of the first width is equal to the utility model claims a first width of. 122 part of the second width is equal to the utility model claims a second width of an embodiment of.
