A reversing unit 57 is installed following the first detecting unit 55. The reversing unit 57 reverses and conveys the postal matter P when the stamp attached to the postal matter P is not recognized by the first detection unit 55, and when the postage stamp is recognized, the postal matter P is rotated normally. Transport as it is.

A second detector 59 is installed in connection with the reversing unit 57. The second detection unit 59 has the same configuration as the first detection unit 55, and detects the stamp of the postal matter P similarly to the first detection unit 55. A stamp portion 61 is installed following the second detection portion 59. The imprinting part 61 imprints by contacting the postal matter P whose stamp has been detected by the second detection part 61. After that, the postal matter P is sent to the stacker unit 63, which is installed subsequent to the stamp unit 61, for example, for ordinary mail,
It is sorted and collected as postal items that are not expressly stamped or stamped. Automatic mail sorting and arranging and stamping machine 37 having the above configuration
Are controlled by the central operation panel 65.

In this automatic mail sorting / sorting and stamping machine 37, when the mail P is put into the supply table 43, the thickness sorting section 47 first performs thickness sorting. After that, the paper sheet transport mechanism 1 removes the foreign matter mixed in, and the sheet is transported while standing upright. Then, the postal matter P is sent to the first and second width sorting sections 49 and 51. The postal matter P whose width has been selected here is sent from the buffer unit 53 to the first detection unit 55 with its front end or rear end aligned. The first detection unit 55 detects the postal matter P by irradiating the postage stamp with light. If the postage stamp cannot be detected here, the postal matter P is reversed.
Turn over at 7. After that, the second detection unit 59 detects the stamp again, and the stamp P is stamped on the postal matter P detected here. After this, the stacker unit 63 sorts and collects.

The present invention is not limited to the above embodiment. For example, in the present embodiment, all the transport rollers are driven to rotate by the belt that is in close contact with the pulleys, but this rotation drive may be connected to gears or the like to drive all the transport rollers. Further, various modifications can be made to the extent not changing the gist including the dimensions, material, driving means, etc. of the conveying roller.
