摘要： The device has three conveyor belts (5a,5b,5c), a letter loosening section (9), a stopper (11) with a bending section (11a) and a distance sensor (2) which detects the distance of the forward end of a letter from it. If two letters (10,12) arrive together the sensor detects two letter contacts with the stopper, the time differential of the detector signal is compared with a threshold value, and if the threshold is exceeded a reject command is generated. The letters are bent over a roller (6e) and when the lower one hits the stopper it is bent over while the upper letter continues in a straight line before hitting the stopper and being likewise bent over.

摘要： An overlapped mail detection apparatus and method are disclosed. Since the postcard is shorter than the letter, the change in length is not sometimes detected even when the postcard is displaced. In the case where the exterior of the letter is deformed outward and an overlap is detected from the rise of the tail end of the letter after passing a guide, a thin letter or the like low in rigidity is hard to detect due to the slow rise after deformation in the guide. In view of this, a separator has a bent conveyance path for deforming the exterior of the letter outward. The conveyance surfaces constituting the inner and outer sides of the bent portion of the separator are spaced appropriately from each other. A detector detects the state of the letter surface in the neighborhood of the outer conveyance surface with which the forward end of the letter first comes into contact. An overlap of letters is judged from the result of detection by the detector.

摘要： PROBLEM TO BE SOLVED: To offset static electricity attaching to a paper sheet by a positive and a negative, and to prevent deceleration or stopping by static electricity attraction force between the paper sheet and a fixed guide by using a member lower in electrification than the paper sheet as a supply belt, and using a member higher in the electricifaction than the paper sheet as the fixed guide. SOLUTION: When the electrification of a supply belt 201 and a feed belt 207 is lower than a letter 214, when rubbing these belts, the supply belt 201 and the feed belt 207 are electrified to (-), and the letter 214 is electrified to (+). At this time, when the electrification of a fixed guide 213 is higher than the letter 214, the fixed guide 213 is electrified to (+) and the letter 214 is electrified to (-) by friction when the letter 214 slides on the fixed guide 213, so that static electricity of (+ and -) electrified to the letter 214 is offset and reduced, and attraction force is reduced so that the carrying letter 214 does not decelerate or stop on a guide surface. Therefor, a construction material of the feed belt 207 is formed of rubber, a construction material of the leter 214 is formed of paper, and a construction material of the fixed guide 213 is formed of plastic.

摘要： PROBLEM TO BE SOLVED: To prevent paper sheets from getting under a carrier belt and being broken by providing a guide means having a contact surface with paper sheets so as to be higher than the location of a rear side surface of the carrier belt and so as to be the location of the carrier surface of the carrier belt or below, between the carrier belt and a reference side belt. SOLUTION: Just under a carrier belt 101, a carrier guide 107 is provided. The surface of the carrier guide 107 is extremely smooth so as not to hinder the carrying of paper sheets. On the surface of the carrier guide 107 between the carrier belt 101 and a reference side belt 108, an auxiliary carrier guide 112 is provided. Thickness of the carrier guide 112 is fixed so that the location of the surface of the auxiliary carrier guide 112 may be slightly lower side of the location of the surface of the carrier belt 101. Because the location of the surface of the carrier guide 112 is on an upper side of the location of the surface of the carrier guide 107, a flap part in a letter to be a paper sheet to be carried becomes difficult to get in a lower side of the carrier belt 101 and the flap part can be prevented from being torn.

摘要： PROBLEM TO BE SOLVED: To reduce frequency with which a following document is entangled in a document having a window part, by providing a protrusion projecting to an accumulation space so as to contain a thickness direction of a paper sheet and in a range from a front frame member on a top side in a carrying direction to a half of a length in the transportation direction. SOLUTION: The cross section of a protrusion 111 is trapezoidal, two surfaces, a surface 111a parallel with a base member 18 and a surface 111b tilting so as to close to the base member 18 with closing the upstream side of the surface 111a, project to an accumulation space. The two surfaces share one edge, which is called a cross line K, and the cross line K is a position where a document that is inclined and accumulated such as a document 1C abuts to the protrusion 111. By providing a tilting surface such as the surface 111b, the tip of a document 1 passes at the cross line K smoothly. By projecting the protrusion 111 having a cross point K to the accumulation space, a document is accumulated diagonally to the transportation direction, and the entangling frequency in a window part can be reduced.

摘要： PROBLEM TO BE SOLVED: To stably deliver paper sheets by arranging a loading means on the base frame side from a feed belt only on the side opposite to a delivering means of the line segment connecting the retreat point of a fork means on the base frame to a point of a feed belt means nearest to the delivering means. SOLUTION: A loading bed 1 is formed into a shape not existing on the delivery belt 2 side from a line segment connecting a point of a feed belt 8 nearest to the delivery belt side to the retreat point of a fork 9 on a base frame to prevent a defective delivery. The feed belt 8 has projections like the toothed face of a timing belt, the feeding reliability of letters is improved, and the rotation of the letters by the retreating action of the fork 9 is prevented. Even if the letters are rotated and no feeding force is provided, the letters are easily inserted into a delivery port by a flexible auxiliary guide provided there, and the letters can be delivered without being kept in contact with the delivery belt 2 for a long time.

摘要： PROBLEM TO BE SOLVED: To stably collect paper sheets and to smoothly take them out by setting a part collided with the paper sheets separated from a delivery passage to high friction coefficient and a member in the direction for taking out the collected paper sheets outside the device to a low friction coefficient. SOLUTION: The rear end of a letter 1b is sometimes near a sectional gate 51 and a collecting guide 53 so that following letters 1c, 1b are collided with each other and apt to cause jam. Therefore, a high frictional material is used for a lock means 58 so as not to slip in an arrow (b) direction. A first lock member having high friction characteristics such as rubber is set to 101 and a second lock member having a friction coefficient same as or less than a partition board 57b is set to 102. The second lock member is in this side of the first lock member and has low friction coefficient so that the friction force does not increase. As a result, the letter 1 can be taken out without deformation. A low friction part is provided in this side of the lock means 58 so as to reduce the load in taking out.
