The levers 52 are provided at the tips of levers 52, 52, which are provided on both left and right sides of the main body case 41, respectively, so as to be able to swing up and down about support shafts 51, 51, respectively. The pair of left and right separating claws 50 correspond to the left and right corners of the leading edge side of the uppermost sheet of the sheet material S stacked and stored on the middle plate 45 in the cassette main body case 41, respectively. Reference numerals 53 and 53 designate lever extension portions that extend the tips of the levers 52-52 further forward than the positions of the separation claws 50 and 50. This lever extension 5
3 and 53 are located above the pressure shaft 47, and when the sheet material cassette 40 is removed from the sheet material feeder 20 as shown in FIG. The receiver is stopped by riding on the pressurizing shaft 47 which is pulled up and held at the upper end end position, and the lever 5 is stopped.
2.52 is held in a substantially horizontal rest position and is prevented from rotating downward.

Reference numeral 55 denotes a roller serving as a sheet material conveying member disposed on the upper side of the above-mentioned front upward sheet material guide plate 43, and is free to rotate about the shaft 54. This sheet material conveying roller 55 is a driven roller that is paired with the sheet material conveying roller 28 as a driving roller provided on the feeder 20 side, and as shown in FIG. When inserted and installed, the feeder 20
The sheet material is brought into contact with the front side of the sheet material conveying roller 28 by a corresponding amount.

The roller 55 receives a biasing force in the direction of the roller 28 by a biasing member (not shown), and is pressed into contact with the roller 28 with a predetermined pressure.

56 (Fig. 5) is the left side wall 41 of the cassette main body case 41.
The loaded sheet material side presser 57 provided inside b is a biasing spring plate that appropriately presses the side presser against the side surface of the loaded sheet material.

(3) Storing sheet materials in the cassette 40 Loading and storing sheet materials S in the sheet material cassette 40 is performed using the cassette 40
As will be described later, the cassette 40 is removed from the feeder 20 and removed from the top opening of the main body case 41.
In the state shown in FIG. 9 in which the cassette is removed from the cassette 0, the middle plate 45 inside the cassette main case 41 is at the lowest rotational position where it is collapsed onto the bottom plate 41e of the main cassette case 41, as described above. Further, the separation claws 50-50 are received by the extension portions 53, 53 of the levers 52, 52 provided thereon resting on the pressure shaft 47 which is pulled up and held at the upper end position of the diagonal vertical slot 48. is stopped and the levers 52 are held in a substantially horizontal resting position and are prevented from rotating downward, so they are held at an upper position near the top opening in the main body case 41. . Therefore, the distance between the front end side of the middle plate 45 and the separation claws 50 is kept large, and the operation of loading and storing the sheet materials S into the cassette main body case 41 can be carried out easily and quickly. Note that in the case of the conventional cassette 109 shown in FIG.
It is stable in a state where it is pushed up to the uppermost position on the leading edge side of the intermediate plate 109b, which is always rotationally biased upward at d, or on the leading edge side of the sheet material S on the intermediate plate. Therefore, the main case 10
The sheet materials S are loaded and replenished into the interior of the sheet material S by lifting the intermediate plate 109b and pushing it down against the biasing spring 109d, while dodging the leading edge of the supplied sheet material S from the separating claw 109e. The cassette 40 of the present example, which had the drawback of poor operability for replenishing the cassette, has been improved in this respect as described above.

(4) Attaching the cassette 40 The attachment of the sheet material cassette 40 to the feeder 20 is as follows:
The feeder 20 is connected to the sheet material cassette storage space 23 (FIG. 3), which is composed of the lower surface of the top plate 21 of the feeder 20, the upper surface of the pedestal C, and the inner surfaces of the left and right pedestals 21L to 21H.
From the front side of the cassette, with the rear wall 41d side of the cassette 40 first, and the outwardly projecting elongated flanges 44 on the left and right sides of the cassette.
L and 44R are provided along the longitudinal direction on the inner surfaces of the feeder left and right pedestals 21L and 21R, respectively.Anteroposterior guide grooves 32-3
2 and push it in (in the direction of arrow X in Figure 1).

When the cassette 40 is pushed in sufficiently, the back sides of the left and right protruding edges 42a, 42a of the handle portion 42 on the front side of the cassette will touch the tips 32 of the guide grooves 32, 32 on the feeder 20 side.
The cassette 40 collides with the fist 32a (FIGS. 2-4), and further pushing movement of the cassette 40 is prevented, and the cassette 40 is placed in the normal pushing position with respect to the feeder 20. In this installed state, the front surface of the cassette 40 is almost flush with the front surface of the printer B as shown in FIG.
There is no protrusion from the front of the cassette to the front, and there is no unsightly design caused by the protrusion p-p' of the rear end of the cassette toward the front of the printer as in the prior art shown in FIG. 12.

Insertable distance statement I of the cassette 40 with respect to the feeder 20
(Fig. 1) is larger than the cassette mounting direction dimension 2 of the feeder 20, and it is also possible to insert and use a cassette 46 whose length dimension in the front and rear direction is larger than 2. In this case, In this case, the cassette 40 is placed in the feeder 2.
0 when the cassette is properly installed)
The rear end side, which is the insertion tip side of 40', protrudes from the rear side of the feeder 20 as shown by the two-dot chain line in FIG.
However, as shown in the example in Fig. 11, the protrusions p - p' of the cassettes 109 and 109 are located on the front side of the printer B, which is the main unit. The appearance will be better than if it were formed on the side.

As described above, the sheet material feeding roller 26 disposed on the top plate 21 side of the feeder 20 is a cut-off circular roller (D-shaped cut roller), and is normally in a rotationally stopped state with the inner side 26a of the hole facing downward. Is there a feeder for cassette 40 as shown above? When the cassette main body case 41 is pushed and moved within θ, the upper side of the rear wall 41d of the cassette main body case 41 passes under the downward hole inner side 26a of the sheet material feeding roller 26 and does not interfere with the roller 26.

In addition, until just before the kayak 2 40 is sufficiently pushed into the feeder 20 and is properly mounted, the middle plate 45 is not subjected to the lifting and rotational force by the pressure lever 46 and the bottom plate of the cassette main case 41 4Le, as shown in FIG. 9, and a on the middle plate 45.
The t-sheet material S is also housed in the cassette body case 41 in a horizontal position. Therefore, during the process of pushing the cassette 40 into the feeder 20, the cassette body case 40
The upper surface of the uppermost sheet material of the stored and stacked sheet materials S in the cassette 40 side is sufficiently spaced downward from the downward occluded circle side 26a of the sheet material feeding roller 26. There is no interference between the upper surface of the upper sheet and the feeding roller 26 on the feeder 20 side.

In other words, the feed roller 26 on the feeder 20 side is made into a circular roller, and by keeping the rotation angle posture with the circular side 26a facing downward at all times and in a stopped state, the lower surface of the feeder top plate 21, the mounting base C, etc. Top surface, left and right pedestals 21L-2
Sheet material cassette storage space 2 consisting of the inner surface of 1H
3, the height dimension can be increased, and the sheet material aa storage capacity of the cassette 40 can be increased accordingly.

Immediately before the cassette 40 is sufficiently pushed into the feeder 20 and properly mounted, the pressurizing shaft 4 protrudes outward from the left and right side walls 41b and 41c of the cassette 40.
The left and right end portions 47L and 47R of the feeder 20 are connected to the cam grooves 33 and 47R provided on the inner surfaces of the left and right pedestals 21L and 21R of the feeder 20, respectively.
33, and the subsequent push-moving force of the cassette 40 causes both left and right ends 47L-47R of the pressure shaft 47 to move into the cam grooves 33 and 47R.
33, the pressurizing shaft 47 moves downward from the upper end end point to the lower end end point along the oblique vertical groove 48 with which it is engaged. Along with the downward movement, the pressure lever 46 is rotated clockwise about the support shaft 46a via the tension coil spring 49, and the horizontal arm 46b of the lever 46 is rotated in the upward direction.
By b, the middle plate 45 on which the sheet material S is loaded is lifted from the front end side using the rear side portion 45a as a fulcrum and rotated to a forward upward tilting position.

When the cassette 40 is fully pushed and moved and the cassette mounting is completed, the pressure shaft 47 engages it and reaches the lower end of the diagonal vertical slot 48, and both left and right ends 47L and 47R of the cassette 40 are connected to the cam tA33.・Lower terminal 33a of 33
- It is held and detented at 33a (Fig. 3).

On the other hand, the separation claw levers 52, 52 receive their extended portions 53, 53, and the pressure shafts 47 that receive the IF move downward along the slots 48 as described above. The corner of the leading edge of the aa sheet material S rotates downward in the clockwise direction around , but as the pressing shaft 47 lowers, the leading edge side of the middle plate 45 lifts and rotates, causing the corner of the leading edge of the aa sheet material S to rise in the opposite direction. Separation claws 50-50 are received at the corners to prevent further downward rotation, and the pressurizing shaft 57 is separated from the lever extensions 53, 53 by the subsequent downward movement.
When the lever extensions 53 and 53 are separated from the pressurizing shaft 47, the lever extensions 53 are placed on the corner of the leading edge of the 81 sheet material S by their own weight, and function as a separation claw for one sheet material. shall be.

The sheet material conveying roller 55 of the 40 cassettes is the cassette 4.
0 is in contact with the front surface of the sheet material conveying roller 28 on the feeder 20 side (FIG. 1) when the sheet material 0 is completely attached to the feeder 20.

The sheet material feeding device A in FIG. 1 shows the posture and position of each of the above-mentioned members at the time when the cassette 40 is completely attached to the feeder 20.

(5) Operation of feeder 20 In this state, a mode in which the sheet material feeding device 21A is used is selected in the console section of printer B as a main unit, and an image formation start signal is input to the control circuit of printer B. Then, the above-mentioned stepping motor 30 on the feeder 20 side is energized, and the motor is brought into a rotating driving state. Accordingly, gear trains G1-G5 rotate,
The sheet material conveying roller 28 is rotated in the counterclockwise direction in FIG. Further, the sheet material conveyance roller 55 on the cassette 40 side, which contacts the roller 28 and constitutes a roller pair, also enters a driven rotation state. Sheet material feed roller 26 is kept non-rotating by keeping single rotation spring clutch 31 in a clutch-off state. Thereafter, based on the sheet material feeding start signal, the electromagnetic solenoid plunger 31a on the feeder 20 side is temporarily energized from the control circuit on the printer side, so that the one-turn spring clutch 31 is turned on, and the sheet material is fed. The feed roller 26 is the first
It is driven one rotation counterclockwise in the figure.

During one rotation process of the feed roller 26, the arc side 26b of the roller 26 acts on the top surface of the uppermost sheet material of the a-loaded storage sheet material S on the intermediate plate 45, and the feeder 2
A feeding force is applied in the direction opposite to the mounting direction X of the cassette 40 relative to the cassette 40, and the uppermost sheet material is separated one by one by the separating claws 50 and fed out toward the front wall 41a of the cassette 40.

The leading edge of the fed sheet material is connected to the front upward guide plate 43.
The sheet material is introduced from below into the nip portion of the pair of sheet material feeding rollers 27 and 55, is gripped and conveyed upward, and is fed into the printer B from the feeding sheet material receiving hole 19 on the bottom of the printer. Ru. The sheet material fed into the printer passes through the guide plate 19a, is held in the nip between the feed roller 10 and the conveyance roller 12 on the printer B side, and is fed to the transfer section 13. The image forming operation on the printer B side is the same as in the sheet material feeding mode from the multi-feed tray 8 described above.

Thus, one of the sheet material feeding rollers 26 on the feeder 20 side
Each time the rotational drive is performed, the stored sheet materials in the kayak 40 attached to the feeder 20 are fed one by one to the printer B side, and image formation on the fed sheet materials is sequentially executed. be done.

As the consumption of the loaded storage sheet material S in the cassette 40 decreases, the pressure lever 46 of the middle plate 45 is pulled by the coil spring 49.
By sequentially rotating clockwise with the Charsika, it is lifted and rotated sequentially. As a result, the height level of the leading edge side of the uppermost sheet material of the stacked sheet materials S on the intermediate plate 45 is always maintained at a predetermined, almost constant level, and the sheet material S
Separation and feeding of single sheets is always performed stably.

(6) Taking out the cassette 40 To take out the cassette 40 from the feeder 20, hook your finger on the handle 42 on the front side of the cassette and pull it in the opposite direction to the cassette installation direction X as shown by arrow Y in Figure 1. and remove it from the feeder 20.

At the beginning of this cassette extraction movement process, the cams yt on the inner surfaces of the left and right pedestals 21L and 21R of the feeder 20
The left and right ends 47L and 47R of the pressure shaft 47 on the cassette 40 side are disengaged from the 33 and 33, and the pressure shaft 47 becomes free, so that the force that urges the pressure lever 46 to rotate clockwise is reduced. The lever 46 is rotated counterclockwise by the weight of the middle plate 45 and the stacked sheet material S on it, so that the middle plate 45 falls onto the bottom plate surface of the cassette main case 1 as shown in FIG. 9. return. Further, the pressure shaft 47 is also returned to the state where it is pulled up to the upper end position of the oblique vertical slot 48 with which it is engaged.

The separation claws L/bars 52, 52 are held at a rest position in a horizontal position with their extended portions 53, 53 resting on the pressurizing shaft 47 which has returned to the upper end position of the slot 48.

As described above, the sheet material feeding device A of this embodiment is designed so that the user can optionally purchase and install it in combination with the main unit 2iH of a printer, copier, etc. as necessary. It is configured so that it can be easily attached and detached. Further, the sheet material feeding roller 26 of the feeder 20 is made into a hollow circular roller to realize a long slide of the sheet material cassette 40 with respect to the feeder 20, and the sheet material feeding device B is entirely housed in the lower part of the main body device B. Also, the operation side for attaching and detaching the cassette 40 to the feeder 20 of the sheet material feeding device A is the main device B.
Therefore, according to the sheet material feeding device A, the cassette is placed on the front side of the main unit even though it is compatible with Aubuchon by simply increasing the height of the main unit mB a little. 40, the operability is the same as that of the main unit B, and the design provides a sense of unity with the main unit 2tB, making it the most excellent form in terms of operability and design.

Since the feeding direction of the loaded sheet material in the cassette 40 installed in the feeder 20 to the main body device B is the opposite direction to the mounting direction of the cassette 40 to the feeder 20, the cassette 40 is also fed to the main device B for jamming of sheet materials. B
This can be done easily by attaching and detaching from the front side of the
There is no inconvenience for the operator to go behind the main unit B to work.

Even though the sheet material feeding device A consisting of the feeder 20 and the cassette 40 is located at the bottom of the main device B using a long stroke, it is possible to clear sheet material jams and perform all operations from the front side of the device. The reason for this structure is that, despite the long loading stroke of the cassette 40, the sheet material in the cassette is fed in the opposite direction to the loading direction of the cassette 40 with respect to the feeder 20.

In addition, since the sheet material feeding device A consisting of the feeder 20 and the cassette 40 is all located at the bottom of the main unit MB, the height dimension may be slightly changed to accommodate the amount of sheet material S to be loaded and stored in the cassette 40. It only needs to be changed, and the main unit B is not affected at all, that is, it is easy to adapt to the design, and has extensibility in response to changes in specifications.

When inserting and mounting a cassette in the feeding and conveying direction of the sheet material inside the cassette as in the past, the shock of inserting and mounting the cassette may cause the leading end of the stored sheet material to jump out from the leading end of the cassette due to inertia, or In the case of separation claw type cassettes, problems such as strong force being applied to the separation claws may cause deformation or slow movement of the separation claws may occur. If the cassette is inserted and mounted in a direction opposite to the transport direction, the above-mentioned inertial force will be in the opposite direction, so that the above-mentioned trouble will not occur.

The sheet material conveying roller 55 on the side of the guide set 40 may also be a driving roller like the same roller 28 on the feeder 20 side.

■, Other Examples (1) Fig. 10 (A)-(B)/(C) In this example, the sheet material feeding device A is arranged above the printer B as the main device. be.

The sheet material feeding device A has a sheet material feeder 20 and a substantially long flange (44L/
44R) and guide grooves (32-32), the sheet material cassette 40 can be freely inserted and removed, and the cassette 40 is inserted and removed from the front side of the feeder 20. (A) shows the installed state, (B) shows the state in the middle of insertion or removal.

The sheet materials S are stacked on a middle plate 45 in the cassette 40, and the middle plate 45 is pushed up on the leading edge side by a spring 49a. It is located at the left and right corners of the side.

When the cassette 40 is attached to the feeder 20 as shown in Figure (A), the sheet material feeding roller 26 of the feeder 20 is driven one rotation counterclockwise, thereby removing the stacked sheet materials in the cassette 40. The uppermost sheet material S is conveyed one by one in the direction opposite to the mounting direction It is introduced into the contact nip portion of the same roller 55 on the side,
Sheet material 1a on the top side of printer B is guided downward by a downwardly curved guide 43b provided on the cassette side, and corresponds to the sheet material outlet 40a on the bottom of the cassette.
It is fed into printer B through. The sheet material fed into the printer moves from the registration roller 12a to the guide plate 12.
The image transfer section (corona charger) of the photosensitive drum 3 via b
13 to receive the image transfer, and a pair of fixing rollers 15a and 15.
b -> guide plate 16a -> discharge roller pair 16 and is output onto discharge tray 17.

The feeder 20 of the sheet material feeding device A may be built into the top plate of the printer B, which is the main device, or may be configured to be used in combination so that it can be attached and detached to support Aubuchon. In this case, by replacing the feeder 20, various types of Sheets can be fed.

In addition, since the sheet material is introduced from the cassette 40 to the printer B, which is the main unit, by being guided in a substantially vertical direction by the guide 43b, the sheet path can be made shorter than in the past, and the substantially vertical sheet path portion 43b Since the cassette 40 is installed on the side of the cassette 40 that can be freely inserted and removed from the feeder 20, the cassette 40 is not connected to the feeder 20 when handling sheet material jams.
Just by pulling it out, the sheet path section will be opened, making it easy to clear the jam.

Since the cassette 40 is inserted into the feeder 20 with the front side of the feeder part as a reference, when using a cassette containing sheet material that is long in the sheet material feeding direction, it is installed in the feeder 20. When (A
) As shown in the figure, the rear end side of the cassette 40 is the feeder 20.
Alternatively, the power cord H1 and interface cord H2 may extend outward from the rear end surface of printer B, which is the main device, but the power cord H1 and interface cord H2 are connected to the rear end surface of printer B, which is the main device.
Since the printer B cannot be attached to the wall surface J etc. because the printer B and the wall surface J etc. are originally on a business trip, there is a certain distance between the printer B and the wall surface J etc. The protrusion P does not reduce the installation area of the device; on the contrary, since there is no protrusion toward the front side of the device, the device configuration has good design and operability.

In addition, the protrusion P on the rear end side of the force cera) 40 is 1. For example, when the width direction is LTR (8 inches on the short side) and the maximum feed is L
The cassettes for TR (sheet material feeding direction 11 inches) and A4 size (sheet material feeding direction 297 inches recommended) do not protrude from the rear end side of the feeder 20, and are LGL (14 inches).
If the configuration is such that only inch) size cassettes protrude, since LTR/A4 size cassettes are usually used more often, the design will be more coherent without having to travel as shown in the figure (C). .

(2) FIG. 11 In this example, the sheet material conveying member provided on the cassette 40 side is a plate spring, instead of the roller 55 as in the previous example.
It is made of an elastic plate material or sheet material 55' such as a molded material or a sheet material such as Mylar. When the cassette 40 is fully inserted into the feeder 20, the elastic plate or sheet material 55, which serves as a sheet material transporting member on the cassette 40 side, comes into pressure contact with the sheet material transporting roller 28 on the feeder 20 side. Further, both or either one of the front and rear of the sheet material conveyance roller 28 is used as a sheet material guide member.

The sheet material S fed out from the cassette 40 by the rotation of the sheet material feeding roller 26 on the sheet material feeder 20 side is introduced into the suppressing contact portion between the conveying roller 28 and the elastic plate material or sheet material 55', and is guided by the member 55'. and is conveyed almost vertically upward.

The configuration of this example has the advantage that it is inexpensive and that the sheet material guide before and after the sheet material conveyance roller 28 is more reliable.

The feeding roller 26 may be a full-circumference roller type that is controlled to swing toward and away from the sheet material S, as in the present example, instead of being an occluded roller as in the example described above.

〔Effect of the invention〕

As described above, in the sheet material feeding device of the present invention, the sheet material storage section itself, which is attached to and detached from the sheet material feeder section, is provided with the sheet material conveying member, so that the sheet material feeding device of the feeder section can feed the sheet material. The continuous conveyance of the sheet material in the sheet material storage section is always ensured, and the occurrence of sheet material jam troubles immediately after the sheet material is fed out can be greatly reduced.

Furthermore, even if a jam occurs, by pulling out the sheet material storage section from the feeder section, the sheet material conveying member in which the sheet material jam has occurred is also pulled out, making the jam removal work much easier.
