1 to 7 show an embodiment of the present invention. The same components as those of the conventional example are denoted by the same reference numerals, and the same reference numerals are used for the members 1 to 21 described in the section of the related art. As shown in FIGS. 1 and 2, a cam 5 b is formed on a shaft 5 a of the feed roller 5. 31 is a crank, and this crank 31 rotates around a shaft 31a,
A protrusion 31c is provided at one end 31b, and the cam 5
b, and the other end 31d engages with a projection of a separating member described below.

Reference numeral 33 denotes a separating member.
A projection 33b is provided at one end 33a so as to be engaged with the other end 31d of the crank 31. The projection 33b slides on the guide 9 and linearly moves in the accommodation direction of the feeder C. It moves and is constantly urged toward the crank 31 by the tension of the spring 35.

FIGS. 3 to 5 are schematic views of a main part of a card printer in which a feeding device of a feeder C, a printing device and an alignment storage device according to the present invention are combined. The belt 17 is configured to rotate by transmitting a drive from a drive source (not shown) to the transport roller right 11. A platen 23 is disposed substantially at the center of the transport roller right 11 and transport roller left 13, and a thermal head 7 is disposed opposite to the platen 23, and the ink ribbon cassette 2 is engaged with the thermal head 7.
5 are arranged. The thermal head 7, the ink ribbon cassette 25, and the platen 17 constitute a printing device.

The transport section 29 of the card C is provided with a position fixing roller 41 and a moving roller 43. The moving roller 43 is opposed to the rotatable position fixing roller 41, and the card is higher than the position fixing roller 41. It is located on the downstream side of the feeding path P of C and is configured to be swingable, and is always urged by the position fixing roller 41 by the tension of a spring (not shown). In response to the rocking movement. The position fixing roller 41 and the moving roller 43 are connected to the transport roller left 13 by gears (not shown) and are rotated.

Reference numeral 45 denotes an alignment plate. The alignment plate 45 swings around a shaft 45a, and a regulating portion 45b for regulating the swing is formed at a tip end thereof. 3 (not shown). 47 is a stopper, and the stopper 47 has a substantially U-shaped cross section, and the restricting portion 45b abuts on the inside of the U-shape of the stopper 47 so that the swinging of the alignment plate 45 is restricted. ing.

Reference numeral 49 denotes a storage room for the card C, and reference numeral 51 denotes a biasing alignment plate. The biasing alignment plate 51 is formed with a slope 51a and is rotatable about a shaft 51b. The card C is positioned and oscillated, and is constantly urged in the direction of the alignment plate 45 by the tension of a spring (not shown) so that the discharged card C does not fall. The tension of the spring of the alignment plate 45 is set to be larger than the tension of the spring of the biasing alignment plate 51.

Reference numeral 53 denotes a regulating plate which is provided near the shaft 45a of the aligning plate 45 so as to swing substantially at right angles to the aligning plate 45, and is always counterclockwise by the tension of a spring (not shown). The card C is urged in the needle direction and regulates the leading end of the fed card C. When a long card C is manually placed and fed, the regulating plate 5
Reference numeral 3 is designed to open in the clockwise direction against the tension of the spring (not shown).

The operation of this embodiment will be described.
As shown in FIG. 5 to FIG. 5, first, a drive motor (not shown) is driven, and the transport roller right 11 rotates clockwise. The drive of the drive motor is transmitted to the feed roller 5 via a clutch (not shown), and the feed roller 5 rotates once to feed one of the frontmost cards C vertically housed in the housing chamber 2. Send.

At this time, when the feed roller 5 starts rotating, the crank 31 is rotated by the rotation of the cam 5b integral with the feed roller 5 before the feed roller 5 comes into contact with the card C.
When the crank 31 rotates clockwise through the engagement between the other end 31d and the projection 33b, the separating member 33 is pushed back by the overlap of the feed roller 5 and the card C, and only one card C is Move to a position where you can pass.

When the card C is fed between the conveyor belt 17 and the pinch roller 19 by the subsequent rotation of the cam 5b of the feeding roller 5, the separating member 33 returns to the original position by the tension of the spring 35. It has become. The time when the separating member 33 returns to the original position is not limited to the above time as long as the leading end Ca of the card C has passed through the separating member 33.

In the second embodiment shown in FIGS. 6 and 7,
As means for moving the position of the separating member 33, a solenoid 61 and a spring 63 are used. Solenoid 6
When the card C is fed between the conveyor belt 17 and the pinch roller 19, the solenoid 61 is turned off, and the spring 61 is turned on. The separation member 33 is returned to the original position by the tension of 63. The positional relationship of the separating member 33 is the same as in the first embodiment.

The printing and storage of the card C will be described. When the card C is fed between the belt 17 and the pinch roller right 19, the card C is positioned at a position suitable for printing by rotating the belt 17 in the clockwise direction. The character or image information is transferred to a predetermined position of the card C by the thermal head 7 controlled by a CPU (not shown), and when the transfer is completed, the card is moved by the belt 17, the pinch roller left 21, the position fixing roller 41 and the moving roller 43. C is stored in the storage room 49.

The first card C fed is brought into contact with the alignment plate 45 and the slope 51a of the biasing alignment plate 51, and swings the alignment plate 45 in the clockwise direction. The card C is swung in the counterclockwise direction, and finally the card C is pushed out in the direction of the biasing alignment plate 51 by the tension of the spring of the alignment plate 45, and is stored between the alignment plate 45 and the biasing alignment plate 51. The card C fed after the second is the alignment plate 45
And the flat surface of the card C ejected last time.
5 is swung in the clockwise direction, the biasing alignment plate 51 is swung in the counterclockwise direction, and the card C is pushed out toward the biasing alignment plate 51 by the tension of the spring of the alignment plate 45.
The card is stored between the alignment plate 45 and the card C ejected last time.

[0021]

According to the present invention, a plurality of vertically stored plate-like feeders are pressed against a half-moon feed roller by a pressing means, and fed by rotation of the half-moon feed roller. In the feeding device of (1), before the half-moon feeding roller starts rotating and comes into contact with the plate-like feeder, the separating member is pushed back by an overlap of the half-moon feed roller and the plate-like feeder. Since the plate-like feeder moves to a position where only one sheet can pass,
Following rotation of the half-moon feed roller, only one of the plate-shaped objects is fed, and after the leading end of the plate-shaped object has passed through the separating member, the separating member is Since it is configured so as to return to the original position where one sheet is not passed, there is no need to hook the next plate-like feeder with the burr at the end of the plate-like feeder and carry the double feed together.
