Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic transfer device, and in particular, the present invention relates to an automatic transfer device that transfers characters, etc. protruding from the surface of plastic medical examination cards used in hospitals, cash cards used in banks, etc. to paper. The present invention relates to an automatic transfer device for transferring images to a computer.

Although various types of automatic transfer devices such as plastic cards, so-called electric imprinters, have been provided, they generally have a drawback that the device configuration is complicated, and it is difficult to make the device compact.

Furthermore, in practice, the following automatic transfer devices have been proposed.

In other words, the sheet printing apparatus proposed in Japanese Patent Publication No. 53-38964 places a plastic card on a platen in the base part, further places a sheet material on top of the plastic card, and By lowering the frame to the frame and pushing a pressure roller formed in the frame to roll by a chain drive, raised characters of a plastic card are printed on the sheet material. be.

However, this device has the disadvantage that the mechanism itself tends to be large because the pressure roller is driven by a chain.

In addition, in this device, as a structure for bringing the pressure roller into contact with the sheet material with an appropriate pressure force, a diagonally upward arcuate cam slot is formed in the side plate of the base part, and a horizontal cam slot is formed at the upper end of this cam slot. A follower pin, which is provided on an operating arm that forms a cam slot extension that faces slightly upward at a slight angle and that is rotatably supported at approximately the middle part and that operates the head section by manual pressure, slides within the cam slot. When the follower pin is positioned at the cam slot extension part, the swinging of the operating arm stops, and at that time, the head part is held at a position where the appropriate pressing force is maintained. .

However, the most important thing in this type of device is the appropriate pressure applied by the pressure roller, and it can be said that the printing condition is influenced by the strength of this pressure. In order to move the follower pin to the cam slot extension part, if this extension part faces slightly diagonally upward, the stop position of the follower pin will vary slightly in the vertical direction. Therefore, even if a pressing force adjustment mechanism using elastic means such as a Berebyl washer stack is provided, a stable printing condition cannot always be ensured due to positional fluctuations due to manual adjustment.

On the other hand, the electric imprinter proposed in Japanese Patent Publication No. 55-12865 has a mechanism for sliding the pressure roller in the guide groove via a crank mechanism in order to simplify and compact the drive mechanism of the pressure roller. It has a structure that adopts. And in it,
A mechanism is disclosed in which a roller platen is pressed and rolled by an adsorption electromagnet.

However, with this mechanism, the pressure is set by the strength of the electromagnet, so if there are no fluctuations in voltage, the pressure can be kept constant and good printing conditions can be maintained, but since the electromagnet is activated every time printing is performed, In order to secure a certain degree of adsorption power, the power consumption may exceed the power consumption to operate the roller platen, and cards with magnetic tape etc. attached may be adversely affected by electromagnets. However, there were many defects that made it unusable.

Furthermore, the data recorder proposed in Japanese Patent Publication No. 48-18888 has a printing base plate, such as a credit card, placed at the printing position between the printing plate and the ribbon, and a roller platen and the printing base plate. This is a device in which a sheet of paper is placed between the rollers and a roller platen is rolled under pressure to print raised characters, etc. on a printing base plate on the sheet of paper.

Although the mechanism for operating the roller platen in this device is compact and uses a crank, no mechanism is used to always set the pressing force on the roller platen to an appropriate level. Therefore, it has not yet been possible to solve the above-mentioned drawback that variations in printing conditions tend to occur.

Therefore, in view of the above-mentioned drawbacks, the present invention simplifies the mechanism of an automatic transfer device, makes it compact, maintains the pressing force of the roller at an appropriate level, and reduces power consumption. It was created with the aim of making it easy to operate and to enable the use of cards with magnetic tape attached.The gist of this is that a base with a printing plate is provided, and a frame is The body is pivoted so as to be able to approach the printing plate against the elastic force in the direction of separating the body from the base, and the frame includes a drive mechanism, an ink roller moving mechanism, and a mechanism for connecting the frame to the base. The ink roller moving mechanism is provided with a frame holding mechanism that maintains a close contact state, the driving mechanism is composed of a motor and a clutch means that is linked to the motor and stops at a constant rotation, and the ink roller moving mechanism is arranged such that the ink roller moving mechanism holds the frame facing the printing plate. A horizontal groove is formed in the frame plate part of the body, and the ink roller is mounted on the axis of this horizontal groove.
On the other hand, a crankshaft that is connected to a drive mechanism and rotates half a rotation is mounted on a frame, and an ink roller shaft is connected to a crank pin of this crankshaft via a connecting rod.
The frame holding mechanism includes a locking lever having a locking claw pivotally attached to the frame, and a locking hole in which the locking claw of the locking lever locks formed in the base;
On the other hand, the crankshaft is provided with a cam plate that rotates with the rotation of the crankshaft and swings the locking lever, and the frame body is in close contact with the base to control the switch that operates the drive mechanism. when it oscillates to
When the switch is turned ON and the crankshaft begins to rotate, the cam plate locks the locking pawl and the locking hole to tightly connect the frame and the base. The locking lever is oscillated to maintain the state, and the locking lever is locked to release the locking between the locking pawl and the locking hole when the motor is stopped by the clutch means and the rotation of the crankshaft is also stopped. The reason lies in the fact that the lever is formed in a shape that allows it to swing.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

In the figure, reference numeral 1 denotes a rectangular plate-shaped base, and on this base 1 is disposed a card mounting base 3 on which a plastic card 2A, such as a cash card or a medical examination card, is placed as a printing plate 2. At the same time, on the edge opposite to the edge where the card placement stand 3 is disposed, there is a frame pivot having a U-shape as a whole, to which a lower end corner of a frame 10 (described later) is pivotally attached via a mounting shaft 4. Arrange the mounting plate 5. When the card 2A is placed on the card placement table 3, substantially L-shaped card guide pieces 6 that hold the four corners of the card 2A are elastically projected from the top surface of the placement table 3. A date stamp 7 is provided near the card placement position as required.

The frame body 10 has a pair of rectangular frame plates 11 mounted on stays 1 as appropriate.
2, and their lower end corners are attached to the pivot plate 5 of the base 1 via a mounting shaft 4. In addition, the portion facing the card placement stand 3 is cut out in the same shape as the side surface shape of the card placement stand 3, so that when the frame 10 is swung downward, the card placement stand 3
is adapted to fit into the notch.

A compression coil spring 13 is compressed and arranged between the base 1 and the frame 10 in order to always hold the frame 10, which is slidable upward on the base 1, in an upper position. In the figure, 14 is a frame cover, 15 is a base cover, and a paper receiving plate 1 is placed on the card placement table 3.
6 are arranged.

The frame body 10 has an ink roller 41 that rolls while pressing the printing plate 2 through the paper P, so that the printing plate 2 is placed on the paper P.
an ink roller moving mechanism 40 that transfers the content; a frame holding mechanism 50 that holds the frame 10 in close contact with the base 1 when the ink roller 41 moves;
A drive mechanism 20 for driving and controlling the ink roller moving mechanism 40 and the frame holding mechanism 50 is provided.

The drive mechanism 20 includes a motor 22 having a speed reducer 21 disposed within the frame 10, a drive shaft 23 of which protrudes outward from the frame plate 11, a drive sprocket 24 is fixed, and the drive sprocket 24 is connected to a chain. 2
5 to the clutch sprocket 32 of the clutch means 30.

As shown in FIG. 3, the clutch means 30 includes a clutch shaft 31 mounted between the frame plates 11, a clutch sprocket 32 fixed to the clutch shaft 31, an engaging disc 33, and a shaft near the engaging disc 33. A clutch arm 35 is pivotally connected to the frame plate 11, engages with the engagement disc 33, and is swung by a solenoid 34.
and a limit switch 36 which is turned on when the clutch arm 35 swings, closing the motor drive circuit 66 and driving the yawter 22.

An engaging portion 33A consisting of a notch is formed on the periphery of the engaging disk 33. Further, the tip of the clutch arm 35 is pulled in the direction of the engagement disk 33 by a coil spring 37 disposed on the frame plate 11, and the coil spring 37 causes the clutch arm 35 to protrude approximately at the center in the longitudinal direction. The engaging protrusion 35A is brought into elastic contact with the periphery of the engaging disc 33. The plunger 34A of the solenoid 34 is connected to the clutch arm 35 in order to release the engagement when the engagement protrusion 35A is fitted into the engagement portion 33A.
5 via a link 38. Therefore, when the solenoid 34 is energized, the clutch arm 35 is swung, and as a result, the engagement protrusion 35A of the clutch arm 35 is disengaged from the engagement portion 33A of the engagement disk 33, and the limit switch 36 is turned on. Start the motor 22. The rotation of the motor 22 is linked to the clutch shaft 31 via the reducer 21 and the chain 25, and the clutch shaft 31 starts rotating.

Due to this rotation, the engagement disc 33 rotates, and the engagement protrusion 55A of the clutch arm 35 moves to the engagement portion 33A.
Since the clutch arm 35 is completely disengaged from the clutch arm and comes into contact with the periphery of the engagement disc 33, even when the solenoid 34 is turned off, the clutch arm 35 maintains the swinging position when the solenoid 34 is energized, and therefore the limit switch 36 remains in the ON state. The engagement disk 33 will continue to rotate. Eventually, when the engagement disk 33 rotates until just before the engagement protrusion 35A matches the engagement portion 33A, the motor stop notch 3, which is a slightly shallow arc-shaped cutout on the periphery, is formed.
3B, the clutch arm 35 swings to the depth of this motor stop notch 33B, and the limit switch 36 is turned OFF. By turning off this limit switch 36, the motor 2
2 stops rotation. However, the engagement disc 33 continues to rotate due to inertia, and eventually the engagement protrusion 35A fits into the engagement portion 33A and engages with the clutch shaft 33.
1 will stop rotation.

The ink roller moving mechanism 40 is configured so that the ink roller 41 is mounted on a shaft at a position facing the printing plate 2 when the frame body 10 swings downward. That is, a horizontal groove 42 is formed at the position of the frame plate 11 facing the card mounting table 3, and the ink roller 41 is mounted in this horizontal groove 42 so that the ink roller 41 can move freely within this horizontal groove 42. The ink roller 41 is a well-known type having a comparatively hard synthetic resin cylindrical body impregnated with ink, and is of a type in which the ink is not applied even if it lightly contacts the peripheral surface.
A moving frame 43 is attached to the shaft 41A of this ink roller 41.
is rotatably attached to the back of the movable frame 43, and the other end of a connecting rod 45, one end of which is pivotally connected to a crank pin 44A of a crankshaft 44, which will be described later, is pivotally connected.

The crankshaft 44 is supported by a frame plate 11 on the opposite side of the frame plate 11 on which the clutch means 30 is disposed, and is reinforced with a support plate 46 in order to improve the stability of the shaft support. There is. Frame plate 1 of crankshaft 44
A driven sprocket 47 is fixed to the shaft end projecting outward from the clutch shaft 31, and the driven sprocket 47 is connected by a chain 49 to a driving sprocket 48 fixed to the shaft end of the clutch shaft 31. The diameters of these sprockets 47 and 48 are set so that the diameter of the driven sprocket 47 is twice that of the driving sprocket 48, so that the clutch shaft 31 is
When rotated, the crankshaft 44 rotates by half a rotation.

The frame holding mechanism 50 includes a locking lever 51 pivotally mounted within the frame 10, and a locking hole 53 formed in the base 1 so that a locking claw 52 at the tip of the locking lever 51 locks. , push the locking lever 51 to open the locking hole 53.
and a cam plate 54 that releases the lock from the locking pawl 52.

The cam plate 54 is fixed to the crankshaft 44 of the ink roller moving mechanism 40 and is adapted to interlock with the ink roller moving mechanism 40. Further, the locking lever 51 is located at a substantially central position in the length direction on the mounting shaft 55.
The upper end of this locking lever 51 is connected to the other end of a coil spring 56 whose one end is connected to the frame 10.
6 keeps the locking lever 51 in resilient contact with the cam plate 54 at all times.

The cam plate 54 has a locking lever pushing piece 54A.
Two pieces are formed at an interval of 180 degrees, and in the standby state before starting, the locking lever 51 is swung by the pushing piece 54A, and the position angle is such that the locking pawl 52 can always push into the locking hole 53. be.

In other words, when the starting limit switch 60 (described later) is turned on and the crankshaft 44 begins to rotate, the cam plate 54 locks the locking pawl 52 and the locking hole 53 to connect the frame 10 and the base 1. The locking lever 51 is swung to maintain the close contact state, and the locking pawl 52 and the locking hole 53 are locked when the motor is stopped by the clutch means 30 and the rotation of the crankshaft 44 is also stopped. The locking lever 51 is formed in such a shape that the locking lever 51 is swung in order to release the locking lever.

The solenoid 34 of the drive mechanism 20 is connected to the base 1
It is energized by a starting limit switch 60 disposed at. The starting limit switch 60 has its actuator 60A connected to the mounting shaft 5 of the locking lever 51.
5, and is turned on when the frame body 10 swings downward and the ink roller 41 comes into contact with the paper P placed on the printing plate 2.

As shown in FIG. 8, this starting limit switch 60 is connected to an electrolytic capacitor 61, a diode 62, etc., and constitutes a starting circuit 63 as a whole.

In other words, the 100V AC power supply is connected to the diode bridge 6.
4 and smoothed through a resistor 65 to obtain a direct current. On the other hand, the a contact 60A and the b contact 60B of the limit switch 60 are connected in series via a common terminal 60C, and the b contact 60B is connected to the positive side of the DC power supply via a resistor 65, and the a contact 60A is connected in series with the limit switch 60. One end of the solenoid 34 is connected to the solenoid 34, and the other end of the solenoid 34 is connected to the negative side of the DC power source. Furthermore, the common terminal 60C of the limit switch 60 and the negative side of the DC power supply are connected to charge the electrolytic capacitor 61.

Therefore, the electrolytic capacitor 61 is normally charged via the b contact 60B of the limit switch 60, and the limit switch 60 is turned on and the solenoid 3 is switched on by switching the contacts 60A and 60B.
4 is excited by the electric charge charged in the electrolytic capacitor 61. Such a starting circuit 63
By doing so, it is possible to form a starting circuit 63 that consumes no power even if the device is left plugged into an outlet or the like, and can stand by and be ready for use at any time. Furthermore, even if the frame body 10 is left lowered during operation,
Since the electrolytic capacitor 61 is not charged, the inconvenience caused when the ink roller 41 moves horizontally again disappears.

In use, a plastic card 2A such as a medical examination card or a cash card is placed on the card table 3, and the required paper P is placed on the card 2A, such as a medical record, prescription, etc. Also, if it is a cash card, a shopping statement etc. will be placed there. Next, by pushing the upper part of the frame 10 downward by hand, the frame 10 swings downward and the ink roller 41 is brought into contact with the paper P.

At this time, the starting limit switch 60 is actuated to energize the solenoid 34. This solenoid 34
The clutch shaft 31 rotates once due to the excitation. During this one revolution, the crankshaft 44 makes a half revolution,
By this half rotation, the locking lever 51 is initially moved to the cam plate 5.
The locking pawl 52 is swung by the rotation of the locking hole 53 and inserted into the locking hole 53.
Lock 2. At the same time, the crank arm 44B rotates by half a rotation due to the rotation of the crankshaft 44, and the ink roller 41 is moved horizontally by the connecting rod 45. Due to this horizontal movement of the ink roller 41, the ink roller 41 rolls on the paper P while pressing the paper P, and therefore, the paper P has the plastic card 2A.
The characters, etc. on the card 2A can be transferred to the paper P by applying ink only to the parts where the protruding symbols, characters, etc. are located. At this time, the clutch shaft 31 is rotated once by the clutch means 30 by the excitation signal of the solenoid 34 as described above and is locked, and the clutch shaft 31 and the crank shaft 44 are in a ratio of 2:1. Since they are connected by sprockets 48 and 47 having a diameter, the crankshaft 44 rotates half a turn to move the ink roller 41 into the horizontal groove 4.
It moves forward or backward within 2.

Note that the horizontal groove 4 of the ink roller moving mechanism 40
2 has a notch with the upper portion slightly bulging out, and this bulging notch 42A prevents the ink roller 41 from coming into strong pressure contact with the paper P when the frame 10 is swung downward. This is a relief portion, and this relief portion prevents ink from adhering to the paper P when the frame body 10 swings downward. In addition, since the card guide piece 6 is elastically protruded above the card placement stand 3, even if the ink roller 41 comes into contact with the card guide piece 6, the card guide piece 6 will not be able to reach the card placement stand 3. This can prevent the paper P from being damaged.

As described above, an example of a transfer machine using the card 2A, a so-called imprinter, has been described, but in addition to this, it can also be used as a stamping machine equipped with a flat printing plate (not shown) in place of the card 2A. Of course.

The present invention is constructed as described above, and a base 1 having a printing plate 2 is provided, and a frame 10 is attached to the base 1.
The drive mechanism 20, the ink roller moving mechanism 40, and the frame 10 are mounted on the frame 10 so that they can be freely approached.
a frame holding mechanism 5 that maintains the state of close contact with the base 1;
0, the device configuration becomes simple. Moreover, since the operation involves placing the paper P between the frame body 10 and the base 1 and pushing the frame body 10 downward, operability can be improved.

The ink roller moving mechanism 40 forms a horizontal groove 42 in the frame plate 11 portion of the frame body 10 facing the printing plate 2, and an ink roller 41 is mounted on the horizontal groove 42. A crankshaft 44 that is connected to the drive mechanism 20 and rotates half a rotation is mounted on the shaft, and the ink roller shaft 41A is connected to the crank pin 44A of the crankshaft 44 via the connecting rod 45. 44 is rotated at a constant rate, so that the ink roller 41 can be horizontally moved within the horizontal groove 42 via the connecting rod 45. In cooperation with the frame holding mechanism 50, the ink roller 41 rolls while pressing the paper P placed on the printing plate 2, and ink is applied only to the portion of the paper corresponding to the protruding portion of the printing plate 2. It can be transferred by coating.

Moreover, since the crankshaft 44 is connected to the drive mechanism 20 and rotates half a rotation, the ink roller 41 moves forward or backward within the horizontal groove 42, which speeds up ink application and reduces transfer time.

The frame holding mechanism 50 has a locking pawl 52 in a state in which the frame 10 is pivoted so as to be able to freely approach the printing plate 2 against the repulsive force in the direction of separating the frame 10 from the base 1. A locking lever 51 is pivotally attached to the frame 10, and a locking hole 53 is formed in the base 1 to lock the locking claw 52 of the locking lever 51. A cam plate 54 is provided that rotates with the rotation of the crankshaft 44 to swing the locking lever 51.
When the switch 60 that operates the switch 60 is turned on and the crankshaft 44 begins to rotate, the locking claw 52 and the locking hole 53 are locked to maintain the close contact between the frame 10 and the base 1. Swing the stop lever 51, and
When the motor 22 is stopped by the clutch means 30 and the rotation of the crankshaft 44 is also stopped, the locking pawl 52
In order to release the locking between the locking hole 53 and the locking lever 5
Since the frame 10 and the base 1 are formed in a swinging shape, the locking claws 52 and the locking holes 53 ensure that the frame 10 and the base 1 are in close contact with each other and that the close contact state is always maintained in the same state. By doing so, the frame body 10 can be securely latched to the base 1 in order to be fixed while maintaining the appropriate pressing force of the ink roller 41. The frame body holding mechanism 50 can be operated in conjunction with the ink roller moving mechanism 40, and the frame body 10 will not be disengaged while the ink roller 41 is moving, thereby enabling reliable transfer. Moreover, in the case of conventional ink rollers that use electromagnetic force to press the paper, there is a risk that the magnetic tape on the plastic card may be adversely affected, the device configuration becomes complicated, and power consumption increases. However, according to the present invention, the ink roller 41 is pressed against the paper P by the locking between the locking pawl 52 and the locking hole 53, so this problem can be solved.

Since the drive mechanism 20 consists of a motor 22 and a clutch means 30 that is connected to the motor 22 and stops after a constant rotation, the drive mechanism 20 can be operated for a certain period of time simply by applying a starting signal. Control of the ink roller moving mechanism 40 and the frame body holding mechanism 50, which are driven in conjunction with the drive mechanism 20, can be simplified.

In addition, since the switch 60 for operating the drive mechanism 20 is arranged to be turned on when the frame 10 swings into close contact with the base 1, there is no need to provide an external start switch or the like, and the printing plate 2 By placing paper on top and pushing the frame 10 downward to press it against the paper P, the apparatus can be started, making the operation extremely simple.

As explained above, according to the present invention, a device for transferring characters protruding from medical examination cards, cash cards, etc. onto paper has a simple and compact structure, and furthermore, the pressing force of the roller can always be kept at an appropriate level. In addition, it can be provided as a card that can be easily operated without any adverse effect even if it is a card with magnetic tape attached, and furthermore, it can be transferred at any time. It is possible to stand by in the standby state, and it provides various excellent effects such as no power consumption during the standby state.
