2. Description of the Related Art When reading or transmitting information printed on a sheet by an image reading apparatus or a facsimile apparatus, it is sometimes difficult to determine whether the sheet has been read or transmitted. In a device that stacks multiple sheets of paper on a paper tray and automatically supplies and reads and sends them sequentially, when a double feed of paper occurs, some of the sheets are read or sent. The process is completed without being handled. If this happens,
In order to check whether the paper is being read or transmitted later, a stamping device that stamps the processed mark in the paper path of these papers is provided, and the processed mark is imprinted immediately before each paper is discharged. That is being done.

FIG. 11 shows an example of a conventional structure of a processed mark imprinting device. The second feeding roller 4 which feeds a sheet from a processing position (information reading position on the sheet) A is located in the immediate vicinity of the sheet entering side. A stamp 91 is fixedly arranged at one end of a seesaw lever 93 pivotally supported by a fulcrum pin 92, and a spring 94 for urging the stamp 91 in the retracting direction and a solenoid 95 for causing the stamp 91 to advance toward the sheet surface. Immediately before the processed paper is sent out by the second feed roller 4, the solenoid 95 is excited to imprint a read mark on the paper. Reference numeral 3 in FIG. 11 denotes a first feed roller for feeding a sheet to a processing position, and reference numeral 2 denotes a paper feed roller of an automatic paper feeder.

[0004]

A stamping device for a processed mark having a conventional structure as shown in FIG. 11 requires a solenoid 95 and its drive control device, so that the cost of the device is high, and the stamp is formed on paper. Due to the impact when it comes into contact with the surface, the stamp pressure becomes unstable, the unevenness of the density of the imprinted mark etc. is large, the quality of the imprint is poor, the mounting space is large, and it becomes an obstacle to the miniaturization of the device,
Further, there is a problem that the operation noise of the solenoid is loud.

The present invention does not require a new drive source for stamping a processed mark, has a simple structure, has a small device space, and has no impact or noise at the time of stamping. The task was to obtain

[0006]

According to the present invention, there is provided an apparatus for stamping a processed mark, comprising: a drive motor 1 capable of rotating forward and backward; and a paper feed roller 4 rotating in the sheet discharging direction when the drive motor 1 rotates forward. And a stamp drum 52 having a stamp surface 5 protruding at one or a plurality of positions on a peripheral surface is mounted on a roller shaft 44 of the paper feed roller or a stamp shaft 57 provided adjacent to and parallel to the roller shaft 44. A one-way clutch 55 for rotatingly connecting the motor and the stamp drum 52 when the motor 1 rotates in the reverse direction, and holding members 56, 53, 59 for holding the standby position of the stamp drum 52 when the motor 1 rotates forward. Is provided.

In a preferred embodiment of the present invention, the stamp drum 52 is mounted on the roller shaft 44 of the paper feed roller via a one-way clutch 55. In this case, the stamp drum 52 must have an outer periphery having a diameter smaller than the roller diameter of the paper feed roller 4 and a stamp surface 5 having a slightly larger diameter. This configuration can simplify the device structure. Another preferred embodiment in a different aspect of the present invention is that the stamp drum 52 is mounted on a stamp shaft 57 provided adjacent to the paper feed roller shaft 44, and the stamp drum 52 is provided between the drive motor 1 and the paper feed roller 4. Forward transmission 6
And a reverse rotation transmitting device 7 are disposed in parallel, and a forward rotation transmitting one-way clutch 65 that rotationally connects the motor 1 and the paper feed roller 4 via the forward rotation transmitting device 6 when the motor 1 rotates forward. A one-way clutch 75 for reverse rotation transmission that rotationally connects the motor 1 and the paper feed roller 4 via the reverse rotation transmission device 7 when the motor 1 reverses rotation is provided. And a one-way clutch 55 that locks the stamp drum 52 in the paper discharging direction.
This configuration does not reduce the paper throughput.

In the apparatus according to the present invention, a sensor 42 for detecting a sheet end is provided at a position on the sheet entering side immediately adjacent to the sheet holding position of the sheet feed roller 4.
By providing a cut-out portion 51 or a through hole 58 in the sensor and detecting the rotational position of the stamp drum 52 with the photoelectric sensor 54, the stamping position of the stamp on the paper can be accurately controlled.
Further, ink supply devices 81 and 84 for the stamp surface 5 can be provided. When a plurality of stamp surfaces 5 are provided on the stamp drum 52, a plurality of locking pieces 56 for defining the standby position of the stamp drum 52 are provided, and the stopper 59 is selectively advanced and retracted. Is controlled to select the stamp surface 5.

[0009]

In the apparatus according to the present invention, the stamping surface 5 is rolled on the sheet surface by rotating the sheet feeding motor 1 in the reverse direction, and the processed mark is stamped. When the motor 1 rotates forward, the paper feed roller 4 feeds the paper. At this time, the stamp drum 52 rotates to a standby position due to friction in the free direction of the one-way clutch 55, and is stopped by stoppers 53 and 59 provided at the standby position. Rotation due to the friction is prevented and the stopped state is maintained. Stamp drum 52

In addition, a sensor 42 is provided immediately adjacent to the paper entry side of the paper feed roller 4 for feeding the paper in the discharge direction to detect the end of the paper, and the stamped operation of the processed mark is started from this detected position to obtain the processed mark. Can accurately control the stamp position.

In the apparatus according to the present invention, the stamping of the processed mark is performed by the rolling of the stamp surface 5 on the upper surface of the sheet, so that no impact or noise is generated at the time of the stamping.
The quality of the imprinted mark is also improved. Further, by providing ink supply devices 81 and 84 for supplying ink to the stamp surface 5, drying of the ink on the stamp surface 5 is prevented,
The ink density on the stamp surface 5 can always be kept constant, and a high quality processed mark with a constant density can be imprinted.

A plurality of stamp surfaces 5 are provided on the stamp drum 52.
Is effective when a different processed mark is to be imprinted according to a difference in paper or a difference in processing.
In this case, the selection of the processed mark to be stamped is performed by selectively moving the stopper 59 to selectively lock the locking piece 56 with the stopper 59 and changing the standby position of the stamp drum 52. Done by That is, the standby position of the stamp drum 52 may be set so that the stamp surface corresponding to the mark to be stamped rolls on the sheet surface first when the motor 1 is rotated in the reverse direction. The problem of imprinting a plurality of marks on the paper surface can be prevented by limiting the reverse rotation amount of the motor 1 in accordance with the arrangement interval of the stamp surface 5.

The structure in which the stamp drum 52 is mounted on the roller shaft 44 of the paper feed roller 4 via the one-way clutch 55 has the simplest structure and requires no space. In this configuration, when the motor 1 rotates forward, the paper feed roller 4 rotates to feed the paper, and the stamp drum 52
Is stopped at its standby position. When the motor 1 is rotated in the reverse direction, the paper feed roller 4 rotates in the reverse direction to feed back the paper, and in synchronization with the reverse rotation of the paper feed roller 4, the stamp drum 52 rotates and feeds the paper in the reverse direction while the paper is processed. Make a seal. After the motor 1 is rotated in the reverse direction by an amount necessary for the stamping, the motor 1 is switched to the normal rotation, and the stamped sheet is discharged.
Immediately after the start of normal rotation of the motor 1, the stamp drum 52 rotates in the same direction as the paper feed roller 4 due to the friction in the free direction of the one-way clutch 55, and the stamp surface 5 is moved so that the stamping operation is performed again. After rolling at the same position, it rotates to the standby position locked by the stoppers 53 and 59 and stops.

A clutch 4 for preventing reverse rotation of the paper feed roller 4
In the configuration according to the third aspect of the present invention, when the motor 1 is rotated in the reverse direction, the paper stops while being held by the paper feed roller 4 in the free rotation state. During this time, the stamp drum 52
Starts rotating from the standby position, and when the stamp surface 5 comes into contact with the paper surface, the stamp surface 5 rolls on the paper surface to stamp the processed mark while dragging the paper by the frictional force. . After the mark is stamped,
It is the same as that of the second aspect.

The forward rotation transmitting device 6, the reverse rotation transmitting device 7, and their respective clutches 65 and 75 are provided between the motor 1 and the paper feed roller 4. The paper can continue to be fed, thus maximizing the paper throughput. In this structure, during normal rotation of the motor 1, the forward rotation transmission clutch 65 is locked, and the rotation of the motor 1 is transmitted to the paper feed roller 4, and the paper feed roller 4 feeds the paper. When the motor 1 is rotated in the reverse direction, the forward rotation side clutch 65 is free and the reverse rotation side clutch 75 is free.
Is the lock, the one-way clutch 5 of the stamp drum 52
5 is locked, and the reverse rotation of the motor 1 is converted by the reverse rotation transmission device 7 into the forward rotation direction of the paper feed roller 4 to rotate the paper feed roller 4. On the other hand, stamp drum 52
Is rotated by the reverse rotation of the motor 1 so that the stamp surface 5 rolls on the sheet in the sheet feeding direction. Therefore, the stamp surface 5 rolls in the same direction on the surface of the paper being fed in the feed direction by the paper feed roller 4, and the processed mark is stamped. After the imprinting is performed, the reverse rotation of the motor 1 is further continued for a while, so that the sheet comes out of the imprinting position. Thereafter, the motor 1 is returned to the normal rotation, so that the rotation of the paper feed roller 4 is continued. Then, the operation of returning the stamp drum 52 to the standby position is performed.
