1 to 3 schematically show the construction of a business card reversing device according to an embodiment of the present invention. This business card reversing device is attached to a business card printer (not shown),
In order to print the predetermined items on the non-printing surface, the business card paper C having the predetermined items printed on its surface and conveyed in the predetermined direction is turned over and conveyed in the opposite direction with the non-printing surface facing the front side. What is used.

This business card reversing device includes a rotating disk 1 having a diameter substantially corresponding to the length of a side of the business card paper C along the conveying direction.
Card paper C between the driving roller 2 and the driving roller 2
Roller 3 capable of pressing and holding the paper, a pair of supply rollers 4 and 4 for feeding business card paper C between the driving roller 2 and the driven roller 3, and business card paper supplied by the supply rollers 4 and 4. C, a business card position sensor 5 for detecting the rear end, a motor 6 serving as a drive source for rotating the rotating disk 1 and the drive roller 2 simultaneously or only the drive roller 2 in the counterclockwise direction in FIG. Clutch 7 as a clutch means capable of intermittently transmitting the rotation of the motor to the rotating disk 1
And a rotation angle sensor 8 that detects the rotation position of the rotating disk 1 that enables the discharge of the business card paper C.

Reference numeral 9 (FIG. 2) denotes a spring for pressing the driven roller 3 against the rotating roller 2;
FIG. 1 shows a guide for feeding and discharging the business card paper C to and from the rotating disk 1. Further, a controller 11 is provided as control means for outputting a control signal S3 for turning on / off the electromagnetic clutch 7 in response to detection signals S1 and S2 from the sensors 5 and 8.

The operation of the business card reversing device constructed as described above will be described. The driving roller 2 is driven by the motor 6 at substantially the same surface speed as the supply rollers 4 and 4.
In the state shown in FIG. 1A, the electromagnetic clutch 7 is in the off state, and the rotation of the motor 6 is not transmitted to the rotating disk 1. Therefore, the rotating disk 1 stops at the position shown in FIG. I have.

In this state, the business card paper C is supplied to the supply rollers 4 and 4.
Is fed in the direction of arrow X, and the front end thereof is
When it reaches a position sandwiched between the roller and the driven roller 3,
The sheet is further transported while being pressed and held between these rollers. When the business card position sensor 5 detects that the rear end of the business card paper C has passed the predetermined position and that substantially the entire business card paper C is supported by the rotating disk 1, the controller 11 receives the detection signal S1 and the controller 11 A control signal S3 for turning on the electromagnetic clutch 7 is output. Thereby, the rotating disk 1 starts rotating together with the driving roller 2 by the motor 6 (FIG. 1).
(B)). In the illustrated configuration example, the business card position sensor 5 detects that the rear end of the business card C has passed a predetermined position, but detects that the front end of the business card C or any other location has reached the predetermined position. May be used.

When the rotating disk 1 is rotated by about 180 degrees, FIG.
When the rotation angle sensor 8 detects that the position shown in (C) has been reached, the controller 11 receives the detection signal S2 and outputs a control signal S3 for turning off the electromagnetic clutch 7. As a result, the rotating disk 1 stops rotating and stops at the position, but since the driving roller 2 continues rotating,
The business card paper C pressed and held between the driving roller 2 and the driven roller 3 is discharged in the arrow Y direction. At this time, since the supply rollers 4 and 4 are driven to rotate in the direction opposite to the state shown in FIG. 1A, the discharged business card paper C is turned over by the rotation of the rotary disk 1 so that the non-printing surface becomes the front surface. In this state, the paper is conveyed by the supply rollers 4 and 4 toward a printing unit (not shown) of the printer.

When the trailing end of the discharged business card paper C is detected by the business card position sensor 5, the controller 11 receives the detection signal S1 and the control signal S for turning on the electromagnetic clutch 7 is received.
3 and the rotating disk 1 is driven by the motor 6 to
It rotates toward the initial position of (A). The rotating disk 1 is shown in FIG.
When the rotation angle sensor 8 detects that the initial position (A) has been reached, the controller 11 receives the detection signal S2 and the control signal S3 for turning off the electromagnetic clutch 7 is received.
And the rotating disk 1 stops at the initial position and waits for the next business card paper C to be fed.

In the above embodiment, the motor 6 is used as a single drive source for the drive roller 2 and the rotary disk 1, and the rotation / stop of the rotary disk 1 and the rotation / stop of the rotary disk 1 are performed in cooperation with the sensors 5, 8 and the clutch 7. Although the rotation angle at the time of stop is controlled, separate driving sources may be used for the rotating disk 1 and the driving roller 2. In this case, as shown in FIG.
Is driven by a motor 6 at all times, but a controller 1 that controls a driving source (motor 12) for the rotating disk 1
1 is a motor 1 in response to a detection signal S1 from the sensor 5.
2 is turned on and the rotating disk 1 is rotated in the same direction as the driving roller 2 to invert the business card paper C, and the business card paper is inverted by turning off the motor 12 in response to the detection signal S2 from the sensor 8. A control signal S4 is output so that C is discharged by the driving roller 2 and the driven roller 3.

FIG. 5 shows the supply roller 4 in each state of paper feeding (FIG. 1A), reversing (FIG. 1B), paper discharging (FIG. 1C), and paper discharging to paper feeding. 4 is a table showing operating states of the rotating disk 1 and the driving roller 2. S shown below the table
1 and S2 are detection signals from the sensor 5 or 8 which trigger the transition from one state to the next state. As is clear from this table, according to the business card reversing device of the present invention, the driving roller 2 can always be rotated in one direction, and the rotating disk 1 simply stops and rotates in response to the sensor detection signals S1 and S2. Since it is only repeated intermittently on the basis of this, there is an advantage that control by the controller 11 is extremely simple.

The drive control means for rotating the supply rollers 4 and 4 in the normal and reverse directions can be shared by the controller 11 or may be provided as means separate from the controller 11.
