FIG. 3 is an overall side sectional view showing an outline of the feeding section when the hopper is down. FIG. 4 is an enlarged side sectional view of the main part of FIG.
As shown in FIGS. 3 and 4, the cassette unit 300 includes a cassette housing unit 310, a cassette hopper 320, and a leading end regulating unit 319. Among these, the cassette casing 310 is provided so as to cover the paper P. Further, the cassette hopper 320 is joined to the cassette housing part 310 at the first joining part 321. The cassette hopper 320 is configured to be able to swing around the first joint portion 321 as a fulcrum. Further, the leading edge restricting portion 319 is provided so as to restrict the position of the leading edge of the paper P stored in the cassette portion when the cassette portion 300 is attached to the recording apparatus main body 101.

When the cassette unit 300 is attached to the recording apparatus main body 101, the position and orientation of the cassette unit 300 are determined by the contact portion 212, the cassette guide unit 213, and the cassette regulating unit 214 provided on the base unit 210. It is regulated.
Specifically, the contact portion 212 is provided so as to regulate the position of the cassette portion 300 in the feeding direction Y.

  Further, the cassette guide part 213 is provided so as to regulate the position in the width direction X of the cassette part 300 and the position in the direction away from the feeding roller 190. Furthermore, the cassette restricting portion 214 is provided so as to restrict the position of the cassette portion 300 in the direction approaching the feeding roller 190. Further, the cassette guide part 213 and the cassette restricting part 214 are configured to restrict the posture of the cassette part 300 in cooperation.

  The feeding roller 190 has an arc part 192, a string part 191, and a support shaft 193. The feed roller 190 transmits the power of the feed motor 104 to the support shaft 193 by a gear wheel train 215 (see FIG. 17) and a known clutch device 216 (see FIG. 17). The fulcrum is provided so as to rotate clockwise in FIGS. 3 and 4.

  Further, the hopper cam portion 219 is configured to rotate counterclockwise in the drawing with the cam shaft 220 as a fulcrum by the power of the feeding motor 104. The pair of return levers 228 and 228 and the lifter unit 221 are configured to rotate as the hopper cam unit 219 rotates. Specifically, the lifter portion 221 is provided so as to be rotatable about the lifter shaft 222 as a fulcrum. The lifter 221 is biased by a hopper spring (not shown) in a direction in which the hopper 225 engaged with the tip of the lifter 221 approaches the feeding roller 190.

  Then, the lifter portion 221 is rotated by the hopper cam portion 219 so that the hopper 225 is separated from the feeding roller 190. This is so-called hopper down. At the tip of the lifter unit 221, a posture regulating unit 223 is provided. And the hopper 225 is urged | biased by the lifter spring 224 at the attitude | position control part side. Here, in the hopper down state, the hopper 225 comes into contact with the hopper restricting portion 227 provided in the base portion 210 and is slightly separated from the posture restricting portion 223.

  Accordingly, the position and orientation of the hopper 225 in the hopper down state can be accurately determined. As a result, when the cassette unit 300 is attached to or detached from the recording apparatus main body 101, the cassette unit 300 may come into contact with the cork material 226, which is an example of a known high-friction member provided on the hopper 225 and the hopper 225. There is no. That is, there is no possibility that the cassette unit 300 is caught by the hopper 225 and the cork material 226 when the attachment / detachment is performed.

Further, the base unit 210 is provided with a preliminary separation unit 217 and a separation pad 218 as a main separation unit. The preliminary separation unit 217 is provided so as to be movable toward and away from the feeding roller 190. Further, the preliminary separation unit 217 is urged toward the feeding roller by an urging means (not shown).
Note that the movement of the preliminary separation unit 217 toward the feeding roller is regulated by a regulation unit (not shown) from the position of the preliminary separation unit 217 shown in FIGS. 3 and 4.

The paper P that has been fed and passed through the preliminary separation unit 217 enters the separation pad 218 and is abutted against it. Here, when a plurality of sheets P pass through the preliminary separation unit 217, only the uppermost sheet P is separated from the excess sheet P by being abutted against the separation pad 218 and further sent downstream in the feeding direction. . This is so-called bank separation. Then, the uppermost sheet P is guided to the sheet guide surface 211 provided on the base unit 210 and sent to the recording unit 143. On the other hand, the excess paper P stopped at the separation pad 218 is returned to the cassette unit 300 by a pair of return levers 228 and 228.
A state where the string portion 191 faces the preliminary separation portion 217, the separation pad 218, and the paper guide surface portion 211 is a reset position of the feeding roller 190.

FIG. 5 is an overall side cross-sectional view showing an outline of the feeding unit when hopper up is performed on Max sheets in which the number of sheets in the cassette unit is the maximum number of sheets that can be placed. FIG. 6 is an enlarged side cross-sectional view of the main part of FIG.
As shown in FIGS. 5 and 6, when the feeding roller 190 rotates clockwise from the state shown in FIGS. 3 and 4, the hopper cam portion 219 rotates counterclockwise. At this time, the engagement between the hopper cam portion 219 and the lifter portion 221 is released, and the lifter portion 221 rotates counterclockwise by the urging force of a hopper spring (not shown).

  Accordingly, the hopper 225 moves in a direction approaching the feeding roller 190. This is so-called hopper up. The hopper 225 is engaged with the notch 324 of the cassette hopper 320 of the cassette unit 300 and moves the cassette hopper 320 and the paper P in a direction approaching the feeding roller 190. Accordingly, the uppermost sheet P comes into contact with the feeding roller 190. At this time, the rotational force of the feeding roller 190 is transmitted to the uppermost sheet P due to the friction between the feeding roller 190 and the uppermost sheet P. That is, the feeding force is generated on the uppermost sheet P by the frictional force with the feeding roller 190.

Further, when the paper P moves closer to the feeding roller side by the hopper up, the sheet P can pass through the feeding opening 330 provided on the feeding roller side of the leading end regulating portion 319 of the cassette unit 300.
Then, the paper P is fed to the outside of the cassette unit 300 by the feed roller 190 through the feed opening 330 and passes through the preliminary separation unit 217 and the separation pad 218 to the recording unit 143 as described above. Be fed. When the feeding roller 190 returns to the reset position again, the hopper goes down again.
As described above, the sheets P are sequentially fed.

FIG. 7 is an overall side cross-sectional view showing an outline of the feeding unit at the time of hopper up in Min sheets where the number of sheets in the cassette unit is one. FIG. 8 is an enlarged side cross-sectional view of the main part of FIG.
As shown in FIGS. 7 and 8, if the feeding of the paper P is repeated from the state shown in FIGS. 5 and 6, the number of the paper P gradually decreases and finally becomes one. At this time, since the cork material 226 provided in the hopper 225 is in contact with the back side of the paper P, it is possible to reduce the possibility that the paper P slides downstream in the feeding direction.

When the last sheet P is fed, the feeding roller 190 returns to the reset position. Accordingly, the hopper 225 enters a hopper down state.
At this time, since no sheet P remains in the cassette unit 300, it is necessary to replace the cassette unit 300 or to replenish the cassette unit 300 with the sheet P.
Hereinafter, the structure and assembly method of the cassette unit 300 will be described first, and then the attachment and removal of the cassette unit 300 will be described.

Among these, the pair of first housing side claw portions 311 and 311 are extended from the front to the rear of the cassette housing portion 310.
Further, the cassette hopper 320 is joined to the cassette casing 310 by a thin first joint 321 (see FIG. 12A). Here, the first joint portion 321 extends in the width direction X.
Furthermore, the shutter part 340 is joined to the cassette housing part 310 by the thin second joint part 341. Here, the shutter unit 340 is a member for regulating and releasing regulation of the paper P passing through the feeding opening 330.

When assembling, first, the paper P is stored in the cassette housing portion through the hopper side opening 315 at the rear of the cassette portion 300.
Next, the cassette hopper 320 is bent at the first joint portion 321 and rotated in the direction of the arrow.
Then, as shown in FIGS. 11 and 12B, the pair of first thin portions 322 and 322 are moved to the pair of first housings while the pair of first housing side claws 311 and 311 are bent outward in the width direction. Engage with the body side claws 311 and 311.
Accordingly, the plurality of second thin portions 323, 323... Are engaged with the plurality of second housing side claw portions 312, 312.

  At this time, the plurality of second housing side claw portions 312, 312... Bend slightly, but can be easily engaged by further bending the cassette hopper 320. That is, by pushing the central portion of the cassette hopper 320 into the cassette housing 310 in the Y-axis direction, the first thin portions 322, 322 and the second thin portions 323, 323,. 311 and the second housing side claw portions 312, 312... Can be engaged at a time.

  As described above, when the man-hour for storing the paper P is entered, the cassette unit 300 can be assembled in three simple steps. At this time, a tool is unnecessary, and it can be assembled very easily only by bending and engaging. That is, the assembly workability is very good. Moreover, since it is one member by integral molding, cost efficiency is also good. Furthermore, when disassembling, it can be easily disassembled by a procedure reverse to the procedure for assembling.

  In addition, since the first joint portion 321 is assembled by bending, a force for returning to the first joint portion 321 is generated. Accordingly, the cassette hopper 320 is urged in a hopper down direction, which is a direction away from the feeding roller 190. That is, in a state where no external force is applied to the cassette hopper 320, the cassette hopper 320 is lowered by the hopper restricted by the first housing side claw portions 311, 311 and the second housing side claw portions 312, 312,. It becomes a state.

  Furthermore, since the second joint portion 341 is assembled by bending, a force for returning to the second joint portion 341 is generated. Accordingly, the shutter unit 340 is biased in a direction to open toward the outside of the cassette housing unit 310. That is, in a state where no external force is applied to the shutter unit 340, the shutter unit 340 is in a shutter closed state regulated by the third housing side claw unit 313 and the fourth housing side claw unit 314.

Here, the shutter closed state refers to a state in which the paper P is restricted from passing through the feeding opening 330.
On the other hand, the shutter open state refers to a state in which the restriction is released so that the shutter 340 rotates toward the inside of the cassette housing 310 and the paper P can pass through the feeding opening 330. Say.

As will be described in detail later, the third housing side claw portion 313 restricts the shutter portion 340 in the shutter closed state from rotating outward. Further, the fourth housing side claw portion 314 locks the inward rotation of the shutter portion 340 in the shutter closed state. That is, the fourth housing side claw portion 314 stabilizes the shutter portion 340 in the shutter closed state.
The shutter action part opening 317 is provided so that the cassette housing part 310 does not interfere with the action of the shutter opening protrusion 230 and the shutter closing hook 240 described later on the shutter part 340.

Accordingly, the rotation of the shutter unit 340 in the clockwise direction in FIG. 32 stops. Thereafter, the outer surface 345 of the shutter unit 340 is separated from the shutter opening protrusion 230 on the recording apparatus main body side.
In this state, the shutter unit 340 is not completely closed. That is, the shutter unit 340 is in the middle of closing.

FIG. 35 is an enlarged front view showing a state in which the shutter portion closes when the cassette portion is removed, and shows a state in which the cassette portion is moved downstream in the removal direction from the state shown in FIGS. .
As shown in FIG. 35, when the user moves the cassette unit 300 to the downstream side in the removal direction from the state shown in FIGS. 32 to 34, the inner side surface 344 of the shutter unit 340 is connected to the shutter closing hook 240 on the recording apparatus main body side. The hook part 242 is approached.

  Then, the inner side surface 344 of the shutter portion 340 contacts the hook portion 242 and is pressed downward by the hook portion 242. At this time, the fourth thin portion 343 of the shutter portion 340 is strongly pressed against the fourth housing side claw portion 314 on the cassette housing portion side by the pressed force. And the 4th thin part 343 and the 4th housing | casing side nail | claw part 314 bend, and the 4th thin part 343 tries to get over the 4th housing | casing side claw part 314 below.

FIG. 36 is an enlarged front view showing a state in which the shutter portion is closed when the cassette portion is removed, and shows a state in which the cassette portion is moved downstream in the removal direction from the state shown in FIG.
As shown in FIG. 36, when the user moves the cassette unit 300 to the downstream side in the removal direction from the state shown in FIG. 35, the inner side surface 344 of the shutter unit 340 is more strongly pressed by the hook unit 242. At this time, the fourth thin portion 343 is more strongly pressed against the fourth housing side claw portion 314 by the pressed force. Accordingly, the fourth thin portion 343 and the fourth housing side claw portion 314 are further bent, and the fourth thin portion 343 gets over the fourth housing side claw portion 314 downward. That is, the shutter unit 340 is completely closed.

FIG. 37 is an enlarged front view showing a state in which the shutter portion is closed in the removal of the cassette portion, and shows a state in which the cassette portion is moved downstream in the removal direction from the state shown in FIG. . Also, FIG. 38 is a super enlarged front view of FIG. FIG. 39 is a plan view taken along the line QQ ′ of FIG.
In FIG. 38, the shutter portion is shown in a perspective view (indicated by a one-dot chain line) for easy understanding.

  As shown in FIGS. 37 to 39, when the user moves the cassette unit 300 to the downstream side in the removal direction from the state shown in FIG. 36, the shutter unit 340 is pressed by the hook unit 242 and bent. Specifically, when the shutter portion 340 is completely in the shutter closed state, the third thin portion 342 is in contact with the third housing side claw portion 313. And the 3rd housing | casing side nail | claw part 313 has controlled that the shutter part 340 rotates outside from the position of a shutter closed state.

Therefore, even if the shutter portion 340 is further strongly pressed by the hook portion 242, the shutter portion 340 can be rotated in the clockwise direction in FIG. 37 from the shutter closed position by the restriction of the third housing side claw portion 313. Can not.
Here, the shutter portion 340 is formed in an L shape, extends from the second joint portion 341 in the Z-axis direction, and is bent in the X-axis direction. And since the 2nd junction part 341 is extended in the Z-axis direction, the shutter part 340 is comprised so that it may rotate on a Z axis | shaft. Further, in the shutter part 340, the third thin part 342 that engages with the third housing side claw part 313 is provided between the second joint part 341 and the bent portion. Furthermore, the 4th thin part 343 engaged with the 4th housing | casing side nail | claw part 314 is provided in the front end side from the said bent part.

Specifically, the portion where the hook portion 242 presses the shutter portion 340 is configured to be shifted to a position different from the positions of the second joint portion 341 and the third thin portion 342 in the Z-axis direction. That is, in the shutter part 340, the part where the hook part 242 presses the shutter part 340 is configured to be on the tip side from the positions of the second joint part 341 and the third thin part 342.

  Therefore, when the shutter portion 340 is further strongly pressed by the hook portion 242, the contact point S between the third thin portion 342 and the third housing side claw portion 313, and the distal end side of the shutter portion 340 at the second joint portion 341. A rotation moment acts on the shutter unit 340 with an axis formed by two points T as a fulcrum. Further, the plate-like shutter portion 340 at this time extends in the X-axis and Z-axis directions. In other words, the shutter portion 340 is relatively thin in the Y-axis direction, and is easily bent by the force in the Y-axis direction concentrated on a specific location on the inner side surface 344 in a state where the shutter portion 340 is regulated by the third housing side claw portion 313.

As a result, the shutter unit 340 is bent so as to be inclined. More specifically, on the inner side surface 344 of the shutter portion 340, the portion where the hook portion 242 presses the shutter portion 340 is inclined while being bent so as to be lowered downward from the contact point S and the point T on the upstream side in the removal direction.
It is desirable that the position where the fourth thin portion 343 and the fourth housing side claw portion 314 are engaged is configured on the axis formed by the contact point S and the point T. In such a case, even if the shutter portion 340 is bent by the hook portion 242, the position of the fourth thin portion 343 is hardly displaced. Therefore, the said structure can stabilize the engagement with the 4th thin part 343 and the 4th housing | casing side nail | claw part 314. FIG.
