2. Description of the Related Art There is known a mail sorting device that sorts and stacks mails such as letters on the front, back, front and back. In general, this sorter has a main transport path for taking out letters one by one from a supply unit on which a large number of letters are placed and transporting the letters to the section stacking unit. A plurality of stamp detectors, a vertical reversing mechanism, and a stamping device are provided along the main transport path, and a direction reversing path that branches off from the main transport path and joins again is provided. The direction reversing path is provided with a direction reversing mechanism for switching between the forward and backward conveyance directions of the letter.

により切手上に押印される。A letter taken out of the supply unit and conveyed through the main conveyance path is first selectively sent to a vertical reversing mechanism based on the stamp information detected by the stamp detection unit, and the position of the stamp is either upper or lower. It is flipped upside down to unify. Subsequently, the letter is detected by another stamp detection unit to determine whether the position of the stamp is closer to the leading or trailing end of the letter with respect to the transport direction. It is stamped.

And a pressing mechanism that reverses the transport direction and guides the transport direction to the return-side transport belt. The pressing mechanism includes a pressing roller disposed to face the reversing belt with the return-side conveying belt interposed therebetween, and a solenoid connected to the pressing roller. And
By driving the solenoid at a predetermined timing to move the pressing roller toward the reversing belt, the conveying direction of the letter is reversed.

なる。[0008] Also, among the sorting devices, letter jams generated by the direction reversing mechanism are more common than other mechanisms.
This is an obstacle to speeding up the entire apparatus. Further, the transport belt constituting the main transport path, the direction reversing path, and the reversing belt of the direction reversing mechanism are normally driven at the same speed by a common driving mechanism. Therefore, in order to merge the letters distributed from the main transport path to the direction reversing path again to the main transport path at a predetermined timing, it is necessary to consider the reversing operation time of the direction reversing mechanism and to set the inside of the main transport path. The portion extending between both ends of the direction reversing path needs to be longer than the length of the direction reversing path. As a result, it is difficult to reduce the size of the device.
