[Industrial applications]

 The present invention relates to a medium feeding device with a printing mechanism.

[0002]

[Prior Art]

 In an automatic transfer machine installed in a financial institution, a transfer card is used to simplify the button operation of the transfer operation. This transfer card displays information about the recipient and the user, and is issued at the request of the user.

An outline of the automatic transfer machine will be described with reference to FIGS. 5 and 6. The transfer card C inserted from the card insertion slot 1 is taken into the machine by the take-in roller pair 2 and its image information is read by the image scanner 3. The cash or deposit withdrawal card inserted into the cash slot is operated, and remittance is carried out based on this image information. In FIG. 5, reference numeral 4 indicates a magnetic head for reading and writing on the magnetic card, and reference numeral 5 indicates a medium feed roller pair for carrying the magnetic card to be read and written.

The transfer card issuing device 6 is arranged on the back side of the card passage O, and stores card paper (hereinafter referred to as “card”) Ca in a stacked manner and feeds the card to a standby position as needed. Card hopper mechanism 6a, a print head 6b that prints image information on this paper while sending the card Cb sent from this hopper to the standby position toward the card insertion slot 1 side, and a print head in the card transport direction. It is composed of a pair of rollers 6c and 6d which are arranged before and after 6b and which feeds the card paper to be printed. The print head 6b is in contact with the platen roller 6e or is opposed to the platen roller 6e with a gap less than the card thickness. The transfer card C sent to the card passage during the remittance operation is sent to the printing mechanism by the card feed roller pair 5 and the predetermined information such as date and amount is printed and recorded. It is sent by a platen roller 6e and roller pairs 6c and 6d which are rotationally driven in synchronization with each other. A card collection box for collecting and storing unnecessary cards is provided below the standby position (Ca). When the cards are collected, the print head 6b is separated from the platen roller 6e. Reverse the roller pair. The medium feed roller pair 5 is driven by a motor belonging to a read / write mechanism, which is separate from the drive source of the transfer card issuing device 6.

[0005]

[Problems to be solved by the device]

 There is no problem as long as the card sent during printing is held between the roller pair 6d and the platen roller 6e which are driven to rotate by a common drive motor. When the card is held by 5, the feeding speed of the card to the print head 6b varies, the accuracy of the printing pitch decreases, and the appearance of the recording surface of the transfer card deteriorates. Conventionally, the distance between the platen roller 6e and the feed roller pair 5 is set so that the card being printed is not held by the feed roller pair 5. In this case, there is a problem that the card transport path becomes long, which hinders downsizing of the medium feeding device. Also, if the printing operation is not performed after a part of the card is clamped by the feed roller pair 5, the printing pitch will not be disturbed, but the printing area will be reduced and the frequency of card issuance will be reduced. However, there is a problem that the running cost will increase as a result. This problem applies not only to cards but also to media such as passbooks.

Therefore, an object of the present invention is to maintain the accuracy of the printing pitch even if the distance between the platen roller and the medium feed roller pair not included in the printing mechanism is equal to or less than the medium length, and to reduce the printing area. Another object is to provide a medium feeding device with a printing mechanism.

[0007]

[Means for Solving the Problems]

 The medium feeding device with a printing mechanism of the present invention includes a printing mechanism having a print head that is provided so as to be able to come in contact with and separate from a platen roller that rotates at a fixed position, and a roller pair that feeds a medium to be printed, and A head contact / separation mechanism for separating the print head from the platen roller, and a pair of medium feed rollers for feeding / discharging a medium to / from the print mechanism. When the head contact / separation mechanism brings the print head into contact with the platen roller, the operating lever is interlocked with the print head to separate the pair of medium feed rollers from each other.

[0008]

[Action]

 When the medium is printed, the head contact / separation mechanism brings the print head into contact with the platen roller. In conjunction with this, the actuating lever separates the pair of medium feed rollers to interrupt the medium feeding action of the pair of feed rollers. When the print area of the medium separates from the print head, the head contact / separation mechanism operates to separate the print head from the platen roller, and in conjunction with this, the operating lever presses the media feed roller pairs against each other to move the media. send.

【Example】

 Hereinafter, the present invention will be described in detail with reference to an illustrated embodiment, using a card of an automatic transfer machine as a medium. In FIG. 1, reference numeral 60 generally indicates a medium feeding device with a printing mechanism. The medium feeding device 60 includes a platen roller 61a that rotates at a fixed position and a printing mechanism 61 including a print head 61b that is provided so as to be able to come in contact with and separate from the platen roller 61a. A mechanism 62, a medium feed roller pair 50 not included in the printing mechanism 61, and an operating lever 63 interposed between the roller pair 50 and the head contact / separation mechanism 62 are provided.

The print mechanism 61 supports the print head 61b in a fixed manner, and is provided with a head support plate 61d that is swingably supported by a pivot 61c, and an orientation that brings the print head 61b into contact with the platen roller 61a. The head support plate 61d is biased in a biasing direction, and a pair of feed rollers 61f and 61h are provided in the card passage O at the front and rear positions of the print head 61b. The pivot 61c is supported by a stationary frame (not shown). Each roller pair 61f, 61h is composed of drive rollers 61fa, 61ha and pad rollers 61fb, 61hb pressed against them. The drive rollers 61fa and 61ha are rotationally driven in synchronization with the platen roller 61a by a common drive motor.

The head contact / separation mechanism 62 includes a drive motor 62a that is controlled to rotate by a head contact / separation signal, a cam 62c fixed to an output shaft 62b of the motor, and a head support plate 61d. The cam contact portion 62d is formed and is brought into contact with the cam 62c. The cam 62c is rotated half a turn by the head contact / separation signal.

The medium feed roller pair 50 is composed of a drive roller 50a that is rotationally driven by a drive motor different from the drive motor of the printing mechanism 61, and a pad roller 50b that is pressed against this roller. The pad roller 50b is rotatably supported by a support plate 50c that is swingably provided about a swing fulcrum (not shown), and is driven by the drive roller 50a by the elastic force of a pressure spring 50d hung on the support plate. Pressed. The support plate 50c is pivotally attached to a frame (not shown). .

The actuating lever 63 is rotatably supported by a support shaft 63a fixed to a frame (not shown), and one end 63b of the actuating lever 63 is positioned so as to come into contact with the lower peripheral surface of the support shaft 50ba of the pad roller. ing. The other end of the actuating lever 63 extends to a lower position of the cam 62c and forms a cam contact portion 63c that engages with the cam 62c.

Sensors 64 and 65 are provided in the card passage O near the roller pairs 61f and 61h, respectively. The sensor 64 is sent from a standby position (see reference numeral Ca in FIG. 6). It detects the leading edge of the card and outputs a signal for operating the head contact / separation mechanism 62. The sensor 65 detects the front end of the card during printing when the card is issued, and outputs a signal for operating the head contact / separation mechanism 62 at the timing when the print area of this card passes the print head 61b. The detailed operation of these sensors will be described later.

The operation of the embodiment configured as described above will be described. When the transfer card as the medium is not issued, the head contact / separation mechanism 62 causes the head support plate 61 to move by engaging the large diameter portion of the cam 62c with the cam contact portion 62d as shown in FIG. The print head 61b is oscillated and lifted to separate from the peripheral surface of the platen roller 61a, and the rollers 50a and 50b of the medium feeding roller pair 50 are brought into contact with each other. In this case, the card C does not exist in FIG.

In FIG. 2, when the card C is sent through the card passage O in the direction of the arrow a and the sensor 54 detects the leading end of the card C, the drive motor 62a rotates based on the detection signal, and the cam 62c moves. A half rotation is made to engage the small diameter portion with the cam contact portion 62d. The head support plate 61d swings as the cam rotates, and the print head 61b supported by the head support plate 61d is brought into contact with the platen roller 61a. When the print head 61b approaches the platen roller, the tip of the card may be located between the two.

When the cam 62c is rotated, the actuating lever 63, which is in contact with the cam contact portion 63c, is swung counterclockwise about the support shaft 63a, and the pressing spring 50d is pressed. The pad roller 50b is lifted up against the urging force, and the peripheral surface of the pad roller 50b is separated from the drive roller 50a by at least the card thickness.

When the printing operation is executed on the printing area of the card C, the card feeding action of the medium feeding roller pair 50 is released, so that this card is driven by a common drive motor. Since the feed action is performed by the roller pair 61f and 61h and the platen roller 61a without speed fluctuation, the print pitch does not vary.

In FIG. 1, when the sensor 65 detects the front end of the card C sent while being printed, the drive motor 62a operates and the cam 62c operates when the print area of the card C separates from the print head 61b. A half rotation is made to engage the large diameter portion of the cam contact portion 62d, and as shown in FIG. 2, the head supporting plate 61d is rocked and raised. As a result, the print head 61b is separated from the platen roller 61a. Further, as the cam 62c rotates, the actuating lever 63 swings to allow the pad roller 50b urged by the pressure spring 50d to descend and press the card C against the drive roller 50a. This is conveyed.

When the print head is pressed against the platen roller as shown in FIG. 1 and when the print head is separated from the platen roller as shown in FIG. 2, the cam 62c has a biasing spring 61e. Although the force is applied by the pressure spring 50d, these forces are applied at symmetrical positions with respect to the shaft center of the cam and act in directions canceling each other, so that an unbalanced load is not applied to the output shaft 62b.

Next, another embodiment of the present invention will be described with reference to FIGS. 3 and 4. In this embodiment, the structure of the head contacting / separating mechanism is different from that of the above-described embodiment, so that the same reference numerals are allotted to the other components.

An engaging portion 620d forming a part of the head contacting / separating mechanism 620 is formed at the tip of the head support plate 61, and this has an arc-shaped engagement formed at one end of the operating lever 630. The mating portion 630c is engaged. The operating lever 630 is rotatably supported by a support shaft 630a, and its engaging end portion 630b is opposed to the lower peripheral surface of the support shaft 50ba of the pad roller 50b.

A movable portion 620b of a solenoid 620a as a drive source is connected to the head support plate 61d. As shown in FIG. 3, the solenoid 620a is turned off when printing is performed on the card C 1, that is, when the print head 61b is brought into contact with the platen roller 61a, and the solenoid 620a is actuated by the biasing spring 61e. It does not interfere with the movement of the print head. The actuating lever 630, which is interlocked with the swing of the head support plate 61d at this time, separates the pad roller 50b from the drive roller 50a and stops the feeding action of the medium feeding roller pair 50 on the card being printed.

On the other hand, when the sensor 65 detects the card front end and the solenoid 620a is turned on at an appropriate timing, as shown in FIG. 4, the movable portion 620b is attracted and the head supporting plate 61d is biased by the spring 61e. The printing head 61b supported by the rocking is rocked against the urging force of the platen roller 61a. Of course, at this time, the operating lever 630 swings in conjunction with the head supporting plate, the pad roller 50b biased by the pressure spring 50d moves toward the drive roller 50a, and holds the printed card. Allow it to be transported.

[Effect of the device]

 As described above, according to the present invention, when the printing operation is performed on the medium, the conveyance force by the medium feeding roller pair not included in the printing mechanism does not act, so that the print head and the medium feeding roller pair are not operated. Even if the distance between them is shortened, the print pitch does not vary. Also, since it is not necessary to consider the distance between the media feed roller pair and the print head, it is possible to realize a compact device and eliminate the need to reduce the print area of the card, thus increasing the cost of the medium. Will also be good.
