In a paper feed cassette 72 of a paper device 71, a plurality of recording sheets S as recording media are stacked and stored. At the upper front part of the paper feed cassette 72, a paper feed port/ruff 5 is arranged, which is pivotally supported by the free end of the support lever 73 and rotated by a drive source (not shown). The base is rotatably supported by a support shaft 73a.

One side of the paper feed cassette 72 is manually fed by the operator.
A manual paper feed path 76 into which the recording sheet Sa is inserted is provided, and a manual paper feed roller 77 is provided on the downstream side thereof. The recording sheet S in the paper feed cassette 72 is sent to a platen roller 79 in the recording device 70 by a paper feed roller 75 that contacts the topmost recording sheet S and rotates clockwise in the figure. Also, manual paper feed path 7
The manual recording sheet Sa inserted from 6 is fed to the platen roller 79 by a manual paper feed roller 77.

A pair of pinch rollers 80 are in contact with the platen roller 79 of the recording device 70, and the recording sheet S to be fed
(or S a, ) is wound around the roller 80 and conveyed. An ink ribbon]/83 that is supplied from an ink ribbon supply roll 81 and wound onto an ink ribbon take-up roll 82 is in contact with the circumferential surface of the pinch roller 80, and a thermal head 8 that extends along the width direction of the recording sheet S is in contact with the circumferential surface of the pinch roller 80.
5 is the above-mentioned image via the ink ribbon 83/Tyrola 8
It is designed to be attached and detached at 0.

A thermal head 85 that generates heat in response to an image signal transfers ink from an ink ribbon 83 onto a recording sheet 1-5 that is fed from a paper feeding device 71 and wound around a pinch roller 80, thereby recording an image. .

After recording, the recording sheet S is transferred to the driven paper ejection roller 86. The driven paper discharge roller 87 discharges the paper onto the discharge tray 89 .

(C) Problems to be Solved by the Invention However, in the conventional paper feeding device 71 described above, there is a dedicated manual paper feeding path 76 for manually feeding paper.
Since it is necessary to configure the following, there are some drawbacks.

(1) Manual paper feed roller 77 dedicated to manual paper feed path 76
It is also necessary to provide a driving means for driving the roller, which increases the number of parts and increases the cost of the apparatus.

(2) Separately from the cassette paper feed path, manually feed recording sheet S
The space of the device increases because of the provision of a path through which a.

(3) The operation of the drive mechanism differs depending on whether cassette paper feeding or manual paper feeding is used. It is necessary to change the control method, which increases the burden of software development.

Therefore, the present invention provides a paper feeding device that separates recording sheets using a separating claw and feeds them into a cassette, by attaching a separating claw cover that covers the partial separating claw to separate the manual paper feeding path and the stacked paper feeding path. By configuring the paper feed device so that a part of the paper feed device is shared, a dedicated manual paper feed path, a manual paper feed roller, and a drive source for the roller can be omitted. The purpose is to provide

(F) Example A first example of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view of a paper feeder 1 that best represents the features of the present invention.

In the figure, paper feeding device 1 is a paper feeding cassette (loading means).
3, and this paper feed cassette 3 stores several recording sheets S as recording media. A pair of separation claws 5 (separation means) housed in the paper feed cassette 3 either lightly press both corners of the recording sheet S or face each other with a small gap between them. 18 Separation claw 5 is the second
As shown in the figure, it has an I-shape and is supported by a support lever 5a, which is rotatably attached to a suitable position on the paper feed cassette 3 by a support shaft 6. Note that a pressure plate 7 rotatably attached to one end of the paper feed cassette 3 by a support shaft 7a is disposed at the bottom of the paper feed cassette 3, and a compression spring is disposed between the bottom plate of the paper feed cassette 3 and the pressure plate 7. 9
As a result, the leading end of the recording sheet S is urged toward the separating claw 5 side.

A paper feed cassette lid 10 is disposed above the paper feed cassette 3 so that the front part of the paper feed cassette 3 is open. At the top of both sides of the paper feed cassette lid 10, there is a paper feed cassette I.
A guide plate 11 is installed so that it can move according to the recording sheet width with an appropriate gap between the paper feed cassette lid 10 and the guide plate 11. There is. Therefore, the paper feed cassette lid 10 serves as a cover for the paper feed cassette 3, and also serves as a component for the manual paper feed path 12.

The front part of the paper feed cassette lid 10 has an opening 1 in a large part of the center.
The base of a separation claw cover (separation means cover) 15 having a thickness of 1 m +
It is made of a material with a small elasticity of less than o, and its tip covers the separation claw 5. A stopper 15a made of a bent piece facing upward is formed at the tip of the separation claw cover 15, and this stopper 15a serves as a reference against which the tip of the recording sheet Sa that is being manually inserted is abutted. In this embodiment, the separating claw cover 15 is made of an elastically deformable polyethylene film having a thickness of about 0.1!1111 mm and a length of about 50 us with low elasticity.

Above the opening 13 of the separation claw cover 15, a plurality of paper feed rollers (paper feeding means) 16 having a relatively high coefficient of friction, such as silicone rubber, are opposed, and the paper feed rollers 16 are fixed. Both ends of the shaft 16a are rotatably attached to the free ends of a pair of support levers 7, and are driven in the direction of arrow 19 by a power source (not shown). A support shaft 20 to which the base of the support lever 17 is fixed is rotatably installed in a recording device to be described later, and is rotated in the direction of an arrow 21 or the opposite direction by a drive source (not shown). .

The paper feeding device 11 configured in this way is detachably attached to the recording device [2] shown in FIG.

A stacked paper feeding path 8 is formed between the paper feeding cassette lid 10, separation claw cover 15, and the stacked recording sheets S.

Next, there is a cassette feeding system that feeds the recording sheets S one by one from the paper cassette 3 of the paper feeding device 1, and a manual paper feeding path 12.
The operation of manually feeding the recording sheet Sa will be explained using FIG. 2.

FIG. 2(a) shows the state at the time when the uppermost recording sheet S of a bundle of recording sheets S is separated during cassette feeding. Since the procedure of the sheet feeding operation is shown in the flowchart of FIG. 5, the operation will be explained below using FIG. 5 as well. First, when the support lever 7 in FIG. 1 is rotated to a predetermined position in the direction of arrow 21 by the action of an actuator (not shown), the paper feed roller 16 is pressed against the recording sheet S (Step 201...hereinafter referred to as S t e p is abbreviated as S). At this time, the force with which the recording sheet S comes into pressure contact with the paper feed roller 16 is obtained by the compression spring 9 provided in the paper feed cassette 3.

In this state, when the paper feed roller 16 is rotated in the direction of arrow 19 by a drive source (not shown), the frictional force between the paper feed roller 16 and the recording sheet S overcomes the frictional force between the recording sheets S, and the recording sheet S is rotated. In Figure 2, the vehicle tries to move to the left. At this time, since the leading edge of the recording sheet S is held down by the separation claw 5, a compressive force is generated between the separation claw 5 and the paper feed roller 16, and the recording sheet S forms a loop that protrudes upward. The sheet S comes off the separation claw 5 and is separated. Note that the separating claw 5 only has to have the effect of suppressing the advance of the recording sheet S to some extent, and the separating claw 5 is in a state in which it is in contact with the recording sheet S or in a state in which it is opposed to the recording sheet S with a small gap therebetween.

As shown in FIG. 2(a), when the recording sheet S is at its most deflected state, the separation claw cover 15, which can be flexibly and elastically deformed, deforms according to the deflection of the recording sheet S and applies almost no force to the recording sheet S. does not affect

In this state, by continuing to rotate the paper feed roller 16 in the direction of the arrow 19, the recording sheet S is separated into one sheet.
The recording sheet S is conveyed toward the later-described recording section of the recording apparatus 2 (see FIG. 3) (S202).0 and above are methods for separating and conveying the recording sheet S by cassette feeding.

Next, a method of feeding the manual recording sheet Sa by manual feeding will be described.

FIG. 2(b) shows how the recording sheet Sa is manually fed into the paper feeder 1.
The state shown is set to . In the initial state of the paper feeding device 1, the paper feeding roller 16 is moved in the direction opposite to the arrow 2 of the support lever 17.
It is in a lifted state due to rotation in one direction,
A sufficient space is formed between the recording sheet S in the paper feed cassette 3 and the paper feed roller 16 so that another manually fed recording sheet Sa can smoothly pass therethrough.

When manually feeding the recording sheet Sa in this state, the separation claw 5 is covered by the separation claw cover 15, so the recording sheet S does not get caught on the separation claw 5 and is pushed to the stopper 15.
When it reaches a point a and comes to rest against this point, the setting of the manual recording sheet Sa is completed. At this point, the paper feeding device 1 starts feeding the manually fed recording sheet Sa, which has been released from the operator's hand.

The operation of the paper feeding mechanism section is the same as in the case of cassette paper feeding, and will be explained again along the flowchart of FIG.
First, the support lever 17 is rotated to a predetermined position in the direction of arrow 21 by an actuator (not shown), and the paper feed roller 16 is pressed against the manually fed recording sheet Sa (S201). At this time, the pressing force of the manually fed recording sheet Sa to the paper feed roller 16 is applied by the compression spring 9 in the paper feed cassette 3.

In this state, when the paper feed roller 16 is rotated in the direction of arrow 19 by a drive source (not shown), a force is applied to the manually fed recording sheet Sa to send it to the left in FIG. 2. Furthermore, a force that tries to restrain the movement of the manual recording sheet Sa from the recording sheet S in the paper feed cassette 3 acts on the back side of the manual recording sheet Sa. Since the force is smaller than the force for sending it out from the paper cassette 3, the manually fed recording sheet Sa is conveyed toward the recording section of the recording device 2 in the left direction in FIG.
However, since the separation claw cover 15 is configured so that the manually fed recording sheet Sa has stronger rigidity, the separation claw cover 15 having the stopper 15a is transported as shown in FIG. 2(C). As shown in , the free end bends downward and escapes, and as a result, the manual recording sheet Sa is sent out from the paper feed cassette 3 in the same manner as in the case of cassette feeding described above.

At this time, a reaction force acts on the uppermost recording sheet S in the paper feed cassette 3 to cause it to be conveyed to the left in the figure, but this force is prevented from advancing by the separation claw 5. The top record sheet S
is never fed. The above is the separation and conveyance operation of the manual recording sheet Sa by manual paper feeding.

Next, a configuration in which the above-described paper feeding device 1 is applied to a line-type color recording device using a fused thermal transfer method will be described with reference to FIG. 3.

In FIG. 3, a paper feed path 25 consisting of a plurality of guide plates is formed in the recording device 2 on the downstream side of the paper feed device 1, and a platen roller 26 is rotatably disposed at the downstream end of the paper feed path 25. has been done. A switching pawl 29 whose base is pivoted by a support shaft 27 is disposed in the middle of the paper feed path 25, and this switching pawl 29 is urged to rotate in the direction of the hour hand in the figure by a torsion spring (not shown). It is held in the illustrated position by bringing its side part into contact with the stopper 30. A plurality of pinch rollers 31 and 32 for winding and holding the fed recording sheet S (or Sa) around the platen roller 26 are in contact with the circumferential surface of the platen roller 26, respectively, and are driven by the rotation of the platen roller 26. do.

The ink ribbon 35 is coated with yellow, magenta, cyan, and black colors one after the other, and is supplied from the ink ribbon supply roll 33 and taken up by the ink ribbon take-up roll 36. A long numbered head 37 along the axial direction of the platen roller 26 is attached to the ink ribbon 3.
5 and is fixed to the lower surface of the head shift bar 39. The shift lever 39 has its base connected to the support shaft 4.
The shift lever 3 is pivotally connected to the shift lever 3 and is biased in the counterclockwise direction in the figure by the elasticity of a torsion spring (not shown).
The rotation of the head cam 43 is restricted by bringing a roller 42, which is rotatably provided in the F section of 9, into contact with the circumferential surface of the head cam 43.

The head cam 43 is rotatably disposed by a support shaft 43a, and when it rotates in the direction of arrow 45 in response to a signal from the control section, the shift lever 39 swings as a result of the kneading and moves the ink ribbon 35 to the platen roller. 26 or separated from each other. Incidentally, on the upstream side of the paper feed cassette 3, there is formed a retraction path 46 through which the recording sheets S are to be retracted.

An edge sensor 47 for detecting the edge of the recording sheet S is disposed near the platen roller 26 and pinch roller 32.
A discharge path 49 through which the recorded recording sheet S is discharged is provided on the downstream side of the recording sheet S. A driven paper ejection roller 50 rotated by a drive source (not shown) is arranged downstream of the ejection path 49, and a passive paper ejection roller 51 is rotatably arranged below it.

The actuating lever 52, which is rotatably connected to the drive sheet discharge roller 50 at one end, is rotatably supported by a support shaft 53, and the actuating lever 52 has both ends connected to a fixing member 55 of the lever 52, respectively. engaged tension spring 5
It is urged clockwise in the figure by the elasticity 6.

The end of the actuating lever 52 on the driving paper ejection roller 50 side is warped;
It is engaged with the end of the nod 57, thereby restricting rotation of the operating lever 52 due to the elasticity of the tension spring 56. A paper discharge tray 59 is disposed downstream of both paper discharge rollers 50, 51.

FIG. 4 shows an electric circuit configuration for operating the recording apparatus 2 equipped with the above paper feeding device M1.

In the same figure, the prefix 100 is a control unit that receives recorded data, corrects it, and controls various actuators, sensors, etc.
1 is various actuators and sensor parts, 102 is a control part 1
Central processing unit f (CPU) that issues the 00 command
,, 103 is a host interface control unit 103 that exchanges signals with the host computer 106 and receives data; 04 is a ROM unit in which tables and control sequence blocks necessary for correction are written; 105 is a ROM unit that stores received recorded data; Information necessary for storage and correction =-
The RA and M sections 106 that are temporarily stored are a host computer 106 that controls the recording device 2 from the outside.

In the above configuration, the recording operation of the recording apparatus 2 will be explained based on the flowcharts of FIGS. 3 and 5. However, the operation of feeding the recording sheets S one by one from the paper feeder 1 (5
200 to 202) are similar to the operations described above, so the subsequent operations will be described.

First, the recording sheet S fed from the paper feeding device 1 is
The switching claw 29 is pushed away and the platen roller 26 is moved forward.
and the pinch roller 31. Here, the leading edge of the recording sheet S is aligned parallel to the platen roller 26 due to the rigidity of the recording sheet S itself. If this state is detected by a sensor (not shown) (8203
), the rotational operation of the paper feed roller 16 is temporarily stopped (S20
4) By rotating the head cam 43 in the direction of arrow 45, the shift lever 39 is rotated clockwise to bring the thermal head 37 into pressure contact with the platen roller 26 (S2
05).

Next, the platen roller 26 and paper feed roller 16 are rotated (S206), and at the same time, the ink ribbon take-up roll 36 is rotated to wind up the ink ribbon 35 that is conveyed simultaneously with the recording sheet S (S207). When it is detected that the leading edge of the sheet S has passed between the platen roller 26 and the pinch roller 32 and reached the edge sensor 47 (8208), the rotation of the paper feed roller 16 is stopped (S2
09) At the same time, by rotating the support lever 17 clockwise, the pressure contact state between the paper feed roller 16 and the recording sheet S is released (3210).

This state becomes the recording start position, and the recording signal sent from the host computer 106 shown in FIG.
Yellow, magenta,
The ink is transferred onto the recording sheet S by melting the ink ribbon portion of a designated color from among cyan and black. Do not record one screen at a time in this order (3211)
When printing for one screen is completed, the rotation of the platen roller 26 and the ink ribbon take-up roll 36 is stopped, and the thermal head 37 and the platen roller are rotated by rotating the head cam 43 and positioning the roller 41 in the small diameter part. 26 is released (S212). At this point, the data sent from the host computer 106 is completed, and it is determined whether it is OK to finish printing in the specified color (5213), and if it is OK to finish. If printing of the next color is required, the process advances to the next color printing sequence.

In the case of the next color printing sequence, the platen roller 26 is rotated in the opposite direction to the previous rotation direction (counterclockwise in Fig. 3).
By rotating, the recording sheet S is conveyed in the backward direction, and the leading edge of the recording sheet S is returned to the above-mentioned printing position. At this time, the rear end of the recording sheet S is guided by the slope formed at the top of the switching claw 29 and advances into the retraction path 46 in a direction different from that of the paper feeder 1. This operation allows the recording sheet S to move smoothly to the evacuation path 46.
It will not retreat inward and break.

When the leading edge is returned to the printing start position in this way, the thermal head 37 and the platen roller 26 are brought into pressure contact again (3215), and the platen roller 26 is moved in the forward direction (
(clockwise), and the ink ribbon take-up roll 36 is rotated to proceed to the next color one-screen printing process.<: (3211).

In the case of the end sequence, the solenoid 57 is de-energized while the platen roller 26 is rotated in the forward direction.
As a result, the driving paper ejecting roller 50 is brought into pressure contact with the passive paper ejecting roller 51 due to the elasticity of the tension spring 56, and the recording sheet S is ejected onto the paper ejecting tray 59 by rotating the driving paper ejecting roller 50 by a drive source (not shown). (3216).

Through such an operation sequence, the recording sheets S fed from the paper cassette 3 or manually fed one by one are sent from the paper feeding device 1 to the recording device 2.
When performing full color printing, the yellow screen, magenta screen, cyan screen, and black screen are sequentially recorded, or when performing monochrome printing, the specified color screen is recorded once and applied to the ink ribbon. The ink contained therein is transferred onto the recording sheet S, and a recording operation is performed.

FIG. 6 shows a second embodiment of the invention.

In the first embodiment, the base of the separation claw 5 is fixed to the paper feed cassette lid 10, and the movement of the separation claw 5 is controlled by the separation claw 5.
However, the separating claw 5 is not limited to this, and may be of any other type as long as it has a structure that does not affect the deformation of the recording sheet S in the state shown in FIG. 2(a). For example, as shown in FIG. 6, a thin plate having a base rotatably mounted on a support shaft 60 may be used.

FIG. 7 shows a third embodiment of the invention.

In the first embodiment, the paper feed roller 16 is of a type in which a perfectly round roller is moved up and down to press against the recording sheet S and feed the paper at a distance of w1, or the paper feed roller 16 is not limited to this, but for example, A half-moon-shaped paper feed roller 61 having a fixed rotatable support shaft may be used as shown in FIG.

FIG. 8 shows a fourth embodiment of the invention.

In the first embodiment, when the stopper 15a is bent, the leading edge of the manual recording sheet Sa is released, or as shown in FIG.
It is also possible to leave a in a fixed state and use the deflection of the manual recording sheet Sa to pass through the stopper 15a. In Figure 8, manual recording sheet S
After the tip of a bends as shown by the solid line, its elastic force causes the stopper 15.a to bend as shown by the broken line sb. It is designed to overcome a.

In the first embodiment, the separation claw cover 15 is made of polyethylene, but is not limited to this, and may be made of any other material as long as it can be flexibly and elastically deformed, for example, a material with a thickness of about 50 μm. Stainless steel foil may also be used.

In addition, in the first embodiment, a fused thermal transfer type line type color recording device was used as the recording method, but the recording device is not limited to this. If available, it may be another recording device, such as an electrophotographic recording device, an inkjet recording device, or a copying device.

Furthermore, when performing manual paper feeding in the first embodiment,
Although the stopper 15a is used to abut the leading edge of the manually inserted recording sheet Sa, the method of abutting the leading edge is not limited to the stopper 15a, and for example, an abutting roller or the like may be used.

(g) As described in detail, according to the present invention, a separation claw cover (separation means cover) is provided in a paper feeding device that separates recording sheets using a separation claw (separation means) and feeds the paper into a cassette. The following effects can be achieved by attaching the paper so that the downstream portion of the manual paper feed path and the cassette paper feed path are shared.

(1) Is it possible to manually feed paper even if the recording device does not have a dedicated paper feed path for manual paper feed? Since there is no need to provide a driving means for driving, the number of parts of the paper feeding device is reduced, and costs can be reduced.

(2) Since there is no need to provide a manual paper feed path exclusively for manual paper feed in the recording apparatus, this space can be omitted.

(3) Whether you are using cassette paper feeding or manual paper feeding, the operation of the paper feeding mechanism that feeds recording sheets is the same, so there is no need to change the control method for paper feeding operation, and software The burden of development can be reduced.
