Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a copy paper cassette, more specifically, a copy paper cassette, which is loaded with a plurality of stacked sheets of copy paper, and which is detachably attached to a cassette receiver in a copy machine housing. The present invention relates to a copy paper cassette.

<Prior Art> Conventionally, copy paper cassettes have been widely used in transfer type electrostatic copying machines and the like to feed copy paper sheets one by one through a copy paper transport path defined in the electrostatic copying machine. has been done. This type of copy paper cassette generally consists of a box-shaped cassette container into which a plurality of stacked sheets of copy paper are loaded, and the copy paper cassette can be attached to and removed from a cassette receiver defined in the copier housing. It can be installed freely.

On the other hand, in a transfer type electrostatic copying machine, the moisture content of copy paper conveyed through a copy paper conveyance path has a great influence on the image quality of a copied image. That is, in the transfer process of transferring a toner image formed on the surface of a photoreceptor onto a sheet of copy paper, the toner image is normally transferred by applying a corona discharge to the back side of the copy paper. If the electrical resistance of the copy paper is small, the static charge applied to the back side of the copy paper during the transfer process will escape into the machine through the copy paper. Therefore, when the moisture content of the copy paper conveyed through the copy paper conveyance path is high, the electrical resistance of this copy paper decreases, and this causes corona discharge to have an effect on the back side of the copy paper during the transfer process. As a result, the transfer efficiency of the toner image on the photoreceptor decreases, and the image quality deteriorates.

Conventionally, in order to solve the above-mentioned inconvenience, unused copy paper cassettes are stored in a cassette storage box equipped with heating means, and the heating means is controlled during storage. A system designed to dry the copy paper in the cassette storage box, or
As disclosed in Japanese Patent No. 4639, a heating means is provided directly on the copy paper cassette, and when the copy paper cassette is installed in the copy machine main body, the operation of the heating means is controlled by the power supply on the copy machine main body side. The copy paper in the copy paper cassette is dried.

However, if a heating means is provided in the cassette storage box, the copy paper (copy paper that needs to be dried to reduce its moisture content) in the copy paper cassette installed in the copying machine cannot be dried. First, in order to dry such copy paper, it is necessary to remove the copy paper cassette from the copying machine main body and place it in the cassette storage box. It is time consuming and inefficient. In addition, if the copy paper cassette is provided with a direct heating means and the heating means is operated by the power supply on the copying machine main body, the copy paper will be dried when the copy paper cassette is attached to the copying machine main body. However, it cannot be dried at other times (for example, when the copy paper cassette is removed), and therefore, it is necessary to insert the removed copy paper cassette into the copier and start making copies immediately. When carrying out such operations, the copy paper in the copy paper cassette cannot be sufficiently dried, and copy paper containing a large amount of moisture is conveyed through the copy paper conveyance path.

<Object of the Invention> The present invention has been made in view of the above facts, and its main purpose is to provide an improved copy paper that can effectively dry copy paper loaded in a copy paper cassette. The purpose is to provide cassettes.

<Summary of the Invention> According to the present invention, the cassette container is composed of a box-shaped cassette container loaded with a plurality of sheets of copy paper in a stacked state, and is detachably attached to a cassette receiver defined in the copying machine housing. In the copy paper cassette, the cassette container includes a heating means for heating the sheet copy paper loaded therein, a control means for controlling the heating means, and a means for supplying current to the heating means. A copy paper cassette is provided which is operatively controlled by an electrical supply source.

<Preferred Specific Example of the Invention> A specific example of a copy paper cassette constructed according to the present invention will be described below with reference to the accompanying drawings.

Referring to FIGS. 1 and 2, the illustrated copy paper cassette is comprised of a box-shaped cassette container 2, and the cassette container 2 is comprised of a container body 4 and a lid 6. As shown in FIG.

The container body 4 , which may be of a form known per se, extends upright from a substantially rectangular bottom wall 8 , a left side wall 10 and a right side wall 12 that are upright on either side of the bottom wall 8 , and the leading and trailing edges of the quay 8 . It has a front side wall 14 and a rear side wall 16. Therefore, the illustrated container body 4 has a box shape with a bottom wall 8 and four side walls, and the entire top surface is open. In a specific example, the container body 4
is made of synthetic resin.

Inside the container body 4 described above, a pair of width regulating members 18 and 20 are spaced apart in the width direction (the direction from the lower right to the upper left in Figure 81, the direction perpendicular to the plane of the paper in Figure 2).
is installed. One width regulating member 18 is the left side wall 10
The base is fixed to the left green portion of the bottom wall 8.

Further, the other width regulating member 20 is disposed inside the inner surface of the right side wall 12, and its base is fixed to the right side edge of the bottom wall 8. Each of the width regulating members 18 and 20 has a longitudinal direction (a direction from the lower left to the upper right in FIG. 1),
Rectangular openings 22 and 24 are formed at the upper end of the approximately intermediate portion (in the left-right direction in FIG. 2). A copy paper mounting plate 26 is mounted between the pair of width regulating members 18 and 20. The illustrated copy paper loading plate 26 has a rectangular loading portion 28 and a rear regulating portion 30 that stands upright from the rear edge of the loading portion 28, and support regulating portions 32 and 34 are provided on both sides of the rear end. It is being Then, the upper end of one of the support regulating parts 32 is connected to the bin 3.
The upper end portion of the other support regulating portion 34 is rotatably attached to the inner surface of the width regulating member 20 via a pin 38. Therefore, the above-mentioned copy paper mounting plate 26 is mounted so as to be able to pivot vertically around its rear end. As shown in FIG. 2, a plurality of sheets of copy paper P in a stacked state are placed on this copy paper mounting plate 26. As shown in FIG. That is, as is clear from FIG. 2, a plurality of sheets of copy paper P are placed in a stacked state on the loading portion 28 of the copy paper loading plate 26 in a required manner, and a pair of width regulating members 18 and 20 are copy sheets P in a stacked state
Both edges of the rear end of the copy paper P are as follows:
The rear regulating section 30 of the copy paper loading plate 26 regulates the trailing edge of the copy paper P. In the specific example, a pair of width regulating members 18 and 2
0 and the copy paper mounting plate 26 are made of metal material.

A pair of coil springs 40 (as shown in FIG. (only one side is shown) is interposed. This coil spring 40 acts on the front portion of the copy paper mounting plate 26, and elastically biases the front portion upward in the vertical direction about the bins 36 and 38. Also,
Swing members 42 and 44 are attached to the width regulating members 18 and 20, respectively. One of the swinging members 42 is rotatably attached to the outer surface of the width regulating member 18, and a locking pawl 46 is integrally provided at the upper end of the inwardly bent portion. The other swinging member 44 is rotatably attached to the outer surface of the width regulating member 20, and a locking pawl 48 is integrally provided at the upper end of the inwardly bent portion. Locking claw 4
6 and 48 act on both corners of the leading edge of the uppermost copy paper among the stacked copy papers P placed on the copy paper mounting plate 26, and function to prevent double paper feeding.

Next, the configuration of the lid G will be explained. The illustrated lid 6 has a rear portion 50 that covers the rear side of the open upper surface of the container body 4.
and a front part 52 that covers the front side of the upper surface, and the rear part 5
0 and the front portion 52 are rotatably connected to each other.

That is, in the specific example, protrusions 54 (only one side is shown in FIG. 2) are provided on both sides of the front end of the upper surface of the rear part 50, and protrusions (
(not shown), and the protrusion 54 and the protrusion are pivotally connected via a pin 56 (only one is shown in FIG. 2). Further, bracket portions 58 (see FIGS. 1 and 2) are provided on both sides of the rear end of the lower surface of the rear portion 50.
(only one of which is shown in the figure) is provided, and each of the bracket portions 58 is pivotally attached to the inner end of the above-mentioned bins 36 and 38, respectively. Further, width regulating members 18 are provided on both sides of the front end of the lower surface of the rear portion 50 described above.
Engagement pieces 60 and 62 that can engage with openings 22 and 24 formed in and 20 are provided. Since this is the opening 9, the rear part 50 of the lid body 6 is turned in the direction shown by the arrow 64 (FIG. 2), so that one engagement piece 60 of the rear part 50 is engaged with the opening 22 of the width regulating member 18. At the same time, by engaging the other retaining piece 62 of the rear portion 50 with the opening 24 of the width regulating member 20, the upper rear side of the container body 4 is brought into contact with the rear portion 5 of the lid body 6.
It can be covered by 0. Then, by further rotating the front part 52 of the lid 6 in the direction shown by the arrow 66 (FIG. 2), the front part 52 of the lid 6 also rotates on the upper front side of the container body 4.
It can be covered by 2. In the specific example, the lid body 6
(The rear portion 50 and the front portion 52) are formed from a metal material. In connection with this, an elongated rectangular opening is formed in the rear part 50 of the lid 6, and the opening is covered with a plate member 68 made of a transparent or translucent material.

Therefore, even if the top surface of the container body 4 is covered by the lid 6, it can be confirmed through the plate member 68 whether copy paper is stored therein.

When making copies, the above-mentioned copy paper cassette is removably attached to a cassette receiver (not shown) defined in the copying machine housing of an electrostatic copying machine.

When installing the cassette receiver, the front part 52 of the lid body 6
66 (FIG. 2) to open the top front side of the container body 4, and insert the copy paper cassette in this state into the opening (not shown) formed in the copy machine housing. ) and attach it to the cassette receiver. In this way, the feeding means (not shown) disposed above the cassette receptacle in the copying machine housing passes through the upper front part of the container body 4 to the uppermost copy sheet loaded in the container body 4. and is thus ready for delivery.

The cassette container 2 consisting of the container body 4 and the lid 6 is further provided with heating means for heating and drying the stacked copy sheets P loaded therein. 83 in conjunction with FIGS. 1 and 2, the illustrated heating means 70
includes a first heater 72 and a @2 heater 74, and the first heater 72 and the second heater 74 are attached to the lower surface of the mounting portion 28 of the copy paper mounting plate 26.

The first heater 72 and the second heater 74 are placed on the width regulating member 1 in the specific example instead of on the lower surface of the mounting portion 28.
8 and 20, the rear surface of the rear regulating portion 30 of the copy paper loading plate 26, and the inner surface of the lid 6 (particularly the rear SO).

In the embodiment, the cassette container 2 is further provided with electrical supply and control means 76 (FIG. 3). The electrical supply source for supplying current to the heating means 70 (i.e., the first heater 72 and the second heater 74) is
As in the specific example, it is preferable that the storage battery 78 is configured to be rechargeable. It is located inside. In connection with the storage battery 78, a connector 80 such as a connector is provided on the front surface of the front side wall 14 of the container body 4. The connector 80 is connected to a connector (not shown) such as a connector provided on a cassette receiver (not shown) when the copy paper cassette is detachably attached to the cassette receiver (not shown). Therefore,
The storage battery 78 is electrically connected to the power supply of the main body of the copying machine via the connector 80 when the copy paper cassette is detachably attached to the cassette receiving portion. Although not shown, in the specific example, the control means 76 is arranged in the space existing between the bottom wall 8 of the container body 4 and the mounting portion 28 of the copy paper mounting plate 26, similarly to the storage battery 78. and controls the heating means based on a signal from a detection means to be described later.

Next, various detection means provided in the above-mentioned cassette container 2 will be explained.

Inside the cassette container 4, in the specific example, on the lower surface of the rear end of the loading portion 28 of the copy paper loading plate 26, a first detection means 82 for detecting the environmental condition inside the cassette container 4 is provided.

The first detection means 82 can be constituted by a temperature detection means for detecting temperature, which is known per se, or a humidity detection means for detecting humidity, which is known per se.

In addition, in relation to the copy paper mounting plate 26, the copy paper mounting plate 26
A second detection means 84 is provided for detecting the amount of stacked copy sheets P placed thereon. The illustrated second detection means 84 includes an L-shaped hanging piece 86 provided on the lower surface of the loading portion 28 of the copy paper loading plate 26, and a light-emitting element and a light-receiving element provided on the upper surface of the bottom wall 8. It is composed of a combination of attached reflective photosensors 88. As can be understood from FIG.
When the number of stacked copy sheets P placed on the photo sensor 88 is relatively large, the light from the light emitting element of the photosensor 88 is reflected by the hanging piece 86 and then projected onto the light receiving element. In this way, it is detected that the number of sheets of copy paper loaded is relatively large, and on the other hand, the copy paper loading plate 2
When the number of stacked copy papers P placed on the copy paper plate 6 is relatively small, the copy paper mounting plate 26 is pivoted upward in the vertical direction around its rear end by the action of the coil spring 40. Due to this, the light from the light emitting element of the photosensor 88 is no longer reflected by the hanging piece 86 (therefore, the light from the light emitting element is not projected onto the light receiving element), and thus the number of sheets of copy paper loaded is reduced. Detect relatively few things.

Further, the loading portion 28 of the copy paper loading plate 26 is provided with a copy paper detecting means 90 for detecting whether or not a sheet of copy paper is present on the loading plate 26. The illustrated copy paper detecting means 90 includes a microswitch 92 attached to the lower surface of the loading section 28, and an operating arm 96 (which is swingably attached to a support protrusion 94 provided on the lower surface of the loading section 28). The actuating arm 96 is elastically biased to pivot clockwise in FIG. 2 by spring means, not shown.
The operating portion 96m on the distal end side is configured so that it can protrude upward through a rectangular opening 98 formed in the mounting portion 28 (see FIG. 1).

As can be understood from FIG. 2, the copy paper detection means 90 having such a configuration prevents the operating arm 96 from rotating clockwise when a copy paper is present on the copy paper loading plate 26. Therefore, as shown in FIG. If there is no copy paper on the platen 26, the actuating arm 96 is pivoted clockwise in FIG. 2 by the action of spring means (not shown) so that its actuating portion 96 It projects upwardly through the opening 98 in the rest 28 and the rear end of the actuating arm 96 separates from the actuating piece of the microswitch 92, thus detecting that no copy paper is present on the rest plate 26. Note that the rectangular opening 100 formed in the loading portion 28 of the copy paper loading plate 26 is inserted into the copying machine main body when the copy paper cassette is removably attached to the cassette receiver (not shown). A detecting means (not shown) provided on the side is used to detect whether or not a copy paper is present on the copy paper loading plate 26.

Further, an attachment/detachment detection means 102 is provided in the opening of the connector 80 to detect whether or not a copy paper cassette is attached to a cassette receiver (not shown). The attachment/detachment detection means 102 can be constructed from a contact type switch which is known per se and has a pair of contacts. The attachment/detachment detection means 102 detects that when the copy paper cassette is attached to the cassette receiver, the pair of contacts are not in contact with each other.
In this way, it is detected that the copy paper cassette is installed, and on the other hand, when the copy paper cassette is removed from the cassette receiver, the pair of contacts come into contact with each other, and thus the copy paper cassette is removed. Detects that it is being left.

Signals from the first detection means 82, the $2 detection means 84, the copy paper detection means 90, and the attachment/detachment detection means 102 are sent to the control means 76, as shown in FIG. controls the operation of the heating means 70 based on the various signals mentioned above. Furthermore, the cassette container 2 is provided with a lamp 104 (FIG. 3) that indicates whether or not the entire control system including the heating means 70 is operating. It is housed in a protruding housing 106 (FIG. 2) provided in the.

Next, a control system by the control means 76 will be explained with reference to FIG. 4 showing a flowchart of a control system including the heating means 70.

First, in step n-1, the attachment/detachment detection means 102
Based on the signal from , it is determined whether the above-described copy paper cassette is removably attached to a cassette receiving portion (not shown) in the copying machine housing.

That is, when the copy paper cassette is attached to the cassette receiver and the attachment/detachment detection means 102 is open (OFF), the process proceeds to step n-2, where the copy paper cassette is detached from the cassette receiver and attachment/detachment is detected. If the means 102 is closed (ON), proceed to step n-3. Step n-2
, the power supply on the copying machine main body side, that is, the main switch (not shown) provided on the copying machine main body is closed (ON).
If the main switch is closed, the process proceeds to step n-4, while the main switch is open (O
FF), the process proceeds to step n-3. Therefore, when the copy paper cassette is installed in the cassette receiver (not shown) and the main switch (not shown) is closed,
Electricity is supplied to the copying machine main body side, and the copying machine becomes ready for copying.In step n-4, current is supplied from the power supply of the copying machine main body side to the control means 76, etc., and then in step n-4.
-5, the storage battery 78 is charged by the power supply on the copying machine main body side (therefore, in this case, no current is supplied from the storage battery 78 to the control means 76, etc.). Then, the process moves to step n-6, where the lamp 104 is turned on, indicating that the entire control system including the heating means 70 is in operation. The operation is controlled according to the following.

In the next step n-7, first, the copy paper detecting means 9
Based on the signal from 0, it is determined whether or not a sheet of copy paper is placed on the copy paper mounting board 26. If the microswitch 92 is closed (ON), copy paper is loaded in the cassette container 2, so step n-8 is executed.
Step 9. On the other hand, if there is no copy paper on the copy paper mounting plate 26 and the microswitch 92 is open (OFF), no copy paper is loaded in the cassette container 2, so step 9 is executed. Move to n-9. In the cassette container 2 (if copy paper is present, the first
It is determined whether the detected value of the detection means 82 is outside a predetermined range. That is, when temperature detection means is used as the first detection means 82, when the temperature inside the cassette container 2 is within a predetermined range of, for example, 45° C. or higher, the stored copy paper is sufficiently dried. If the temperature inside the cassette container 2 is outside the predetermined range of, for example, 45° C. or less, there is no need to further dry the copy paper, so the process moves to step n-9. Since the copy paper currently being used contains a large amount of water (that is, the water content is high) and it is necessary to dry the copy paper, the process moves to step n-10 and the heating means 70 is activated as described later. be done.

Further, when a humidity detection means is used as the first detection means 82, the humidity inside the cassette container 2 is, for example, 60 -
When the moisture content is within the following predetermined range, the contained copy paper has a low moisture content and has been sufficiently dried, so there is no need to further dry the copy paper, so step n-9 On the other hand, if the humidity inside the cassette container 2 is outside the predetermined range of, for example, 6° or more, the stored copy paper contains a large amount of moisture, and therefore the copy paper is dried. Since it is necessary to do so, the process moves to step n-1o. In step n-10, based on the signal from the second detection means 84, the copy paper mounting plate 26
It is determined whether a relatively large number of copies of paper are placed on the paper. If a relatively large number of sheets of copy paper are placed on the copy paper loading plate 26, then the process moves to step n-11 (9).
, the first heater 72 and the second heater 74 of the heating means 70 are activated, and thus the copy paper in the cassette container 2 is heated and dried with a relatively large amount of heat. on the other hand,
If a relatively small number of copies are placed on the copy paper mounting plate 26, the process moves to step n-12, where only the first heater 72 of the heating means 70 is activated. In this way, the copy paper in the cassette container 2 is heated and dried with a relatively small amount of heat. step n-11 or step n
During heating in step 12, since the width regulating members 18 and 20, the copy paper loading plate 26, and the lid 6 are made of a metal material with good thermal conductivity, the heat from the heating means 70 is It is well transmitted to the surroundings of the copied copy paper, and the copy paper is effectively heated and dried. Above step n-7
When X moves from step n-8 to step n-9, there is no need to heat the copy paper, so the heating means 70 (i.e.
The operation of the first heater 72 and the second heater 74) is stopped.

Because of this, when the copy paper cassette is installed in the cassette holder (not shown) and the main switch (not shown) on the copying machine main body is closed, the power supply on the copying machine main body is turned off. The operation of the heating means 70 and the like is controlled by this, and at this time the storage battery 78 is also charged as required by the power supply on the copying machine main body side.

On the other hand, in step n-I, it is determined that the copy paper cassette is not installed in the cassette receiver, so step n-
3, or if it is determined in step n-2 above that the main switch on the copying machine main body is not closed and the processing moves to step n-3, the storage battery 78 is switched off by the power supply on the copying machine main body in step n-3. It is determined whether or not the battery is sufficiently charged. When the storage battery 78 is sufficiently charged, the operation of the heating means 70 is controlled using the storage battery 78 as a power source.On the other hand, when the storage battery 78 is not sufficiently charged (discharged due to use). (including cases where the above heating control is stopped).

To explain further, if the storage battery 78 is sufficiently charged, the process moves to step n-13, where the lamp 104 is turned on and the entire control system including the heating means 70 is in the operating state as described above. . Thereafter, the operation of the heating means 70 is controlled using the storage battery 78t in the same manner as described above. That is, first,
In step n-14 following step n-13, it is determined whether or not a copy paper is placed on the copy paper loading plate 26 based on the signal from the copyist detection means 90, and the copy paper is step n-16K #')
, if there is no copy paper, the process moves to step n-17. In step n-16IC, the first detection means 82
It is determined whether it is necessary to operate the heating means 70 based on the detected value from If the detected value of the detection means 82 is within the predetermined range, the process proceeds to step n-17. In step n-18 following step n-16, it is determined based on the signal from the second detection means 84 whether a relatively large number of copies are placed on the copy paper loading plate 26. Ru. Copy paper loading board 26
If a relatively large number of sheets of copy paper are placed on top,
Next, the process moves to step n-19, where the first heater 72 and second heater 74 of the heating means 70 are activated, and thus the copy paper in the cassette container 2 is heated and dried with a relatively large amount of heat. . On the other hand, if a relatively small number of copies are placed on the copy paper mounting plate 26, the process moves to step n-20, and only the first heater 72 of the heating means 70 is turned on. The copy paper in the cassette container 2 is thus heated and dried with a relatively small amount of heat. Step n-15 or step n-16 to step n above
Moving on to -17, since there is no need to heat the copy paper,
The operation of the heating means 70 (first heater 72 and gz heater 74) is stopped.

On the other hand, if the storage battery 78 is not sufficiently charged,
Next, in step n-14, the operation of the first heater 72 and second heater 74 of the heating means 70 is stopped, and furthermore, in step n-21, the lamp 104 is turned off. Therefore, the lamp 104 is turned off to indicate that the storage battery 78 is discharged and the entire control system including the heating means 70 is inactive.

As shown above, if the copy paper cassette is not installed in the cassette receiver (not shown), or if the copy paper cassette is installed in the cassette receiver and the main switch (not shown) is Even when the copy paper cassette is open, the heating means 70 is activated using the storage battery 78 provided in the copy paper cassette.
The heating can be controlled and the stored copy paper can be dried as required.

Although a specific example of a copy paper cassette constructed according to the present invention has been described above, the present invention is not limited to such a specific arrangement, and various modifications and changes can be made without departing from the scope of the present invention. It is.

For example, in the specific example, the heating means 70t is composed of a first heater and a second heater 72;
It may be composed of three or more heaters, and in such a case, it is operated according to the number of copy sheets placed on the copy paper mounting plate 26 in the same manner as in the specific example. It is preferable to vary the number of heaters. In addition, for example, in a specific example, the number of heaters that are activated can be changed depending on the number of copies placed on the copy paper mounting plate 26. However, instead of changing this, the power supplied to the heater is changed according to the number of copies (for example, a part of the waveform of the supplied current is cut to change the power). You can do it like this.
