As shown in FIG. 7, the support portion 52b is formed on the lower surface of the first tray 52 so as to extend in the Y-axis direction, and the supported portion 51e extends in the Y-axis direction on the upper surface of the second tray 51. The second tray 51 is supported on the first tray 52 by being formed and the supported portion 51e resting on the support portion 52b from above. Although FIG. 7 shows the structure of the end portion of the first tray 52 and the second tray 51 in the −X direction, the same configuration is provided at the end portion in the + X direction in a symmetrical structure.

A first rack portion 52a is formed along the Y-axis direction on the −X direction side surface of the first tray 52, and a second rack portion 51a is formed on the −X direction side surface of the second tray 51 in the Y-axis direction. Although they are formed along the same, these rack portions will be described later.

Supported portions 52c are formed along the Y-axis direction on the side surface in the −X direction and the side surface in the + X direction of the first tray 52. FIG. 7 shows a supported portion 52c formed on the side surface of the first tray 52 in the −X direction. The first tray 52 is supported by the rail 60a by inserting the rail 60a provided in the apparatus main body 2 into the lower side of the supported portion 52c as shown in FIG. The supported portion 52c shown in FIG. 7 is supported by a rail 60a (see FIG. 11) provided on the right side of the apparatus main body 2. The rail 60a shown in FIG. 5 supports a supported portion (not shown) provided on the side surface of the first tray 52 in the + X direction.

As shown in FIGS. 5 and 11, the frame 60 forming the accommodating area of the discharge tray 50 in the device main body 2 is provided with a guide slope 60d, and the discharge tray 50 removed from the device main body 2 is used as the device main body 2. The guide slope 60d guides the −Y direction end of the discharge tray 50 to the correct mounting position when the tray is mounted on the tray.
That is, the above-mentioned supported portion 52c is guided on the rail 60a by the guide slope 60d.
As shown in FIG. 6, the first tray 52 is provided with an operation unit 55 and a hook 56, and when the discharge tray 50 is mounted on the apparatus main body 2, the regulation unit 57 (see FIG. 13) is provided. On the other hand, the hook 56 is engaged so that the discharge tray 50 is held so as not to fall off from the apparatus main body 2. In other words, the discharge tray 50 is regulated so as not to be pulled out from the device main body 2.

More specifically, as shown in FIG. 13, the regulating means 58 is provided, and the regulating means 58 includes a hook 56 as a regulated portion, a regulating portion 57, and an operating portion 55 (see FIG. 6). The hook 56 can swing in the + a direction and the −a direction of FIG. 13 around a swing axis (not shown), and the elastic portion (not shown) shows the state shown by the solid line in FIG. 13, that is, the regulation portion 57. It is pressed in the direction (-a direction) in which it can be engaged. In this state, since the hook 56 is in a regulated state in which it can engage with the regulating portion 57, the ejection of the discharge tray 50 in the + Y direction is restricted.

When the operation unit 55 (see FIG. 6) is slid in the + Y direction from this state, the hook 56 swings in the + a direction of FIG. 3 due to the action of a link mechanism (not shown), which is indicated by the alternate long and short dash line and reference numeral 56-1. As described above, it becomes impossible to engage with the regulation unit 57, and the discharge tray 50 is allowed to be pulled out from the device main body 2.
By operating the operation unit 55 (see FIG. 6) as described above, the hook 56 moves, the state in which the withdrawal of the discharge tray 50 is restricted is released, and the discharge tray 50 can be removed from the device main body 2.

The path forming portion 27 is provided with a contact portion 27c as shown in FIG. 16, and in a state where the path forming portion 27 is displaced downward, the discharge tray 50 is configured as shown in FIG. The tip of the 1 tray 52 comes into contact with the contact portion 27c, which hinders the mounting of the first tray 52 and thus prevents the regulating means 58 from switching to the above-mentioned regulated state. With such a configuration, it is possible to prevent the discharge tray 50 from being mounted in an inappropriate state, that is, in a state where the path forming portion 27 is displaced downward, and forcibly mount the discharge tray 50 in an inappropriate state. It is possible to prevent damage due to the above.

Subsequently, as shown in FIG. 5, a support surface 60b is provided under the rail 60a. The support surface 60b supports the second tray 51 when the second tray 51 is housed in the apparatus main body 2. That is, the second tray 51 is supported by the support surface 60b until it protrudes from the device main body 2, and after it protrudes from the device main body 2, it is attached to the support portion 52b (see FIG. 7) of the first tray 52 as described above. Be supported.
In the present embodiment, the rail 60a and the support surface 60b have a predetermined angle with respect to the horizontal plane, and are formed so as to be inclined upward in the + Y direction. As a result, the discharge tray 50 protruding from the device main body 2 is inclined upward in the + Y direction.

A support member is provided in the projecting direction of the first tray 52, that is, in the + Y direction with respect to the + Y direction end of the rail 60a. The support member is provided at a position facing the left side surface of the second tray 51 and a position facing the right side surface of the second tray 51 in the device main body 2. 1 and 5, the support members provided at positions facing the left side surface of the second tray 51 are indicated by reference numerals 63B, and in FIGS. 1 and 8 to 11, they face the right side surface of the second tray 51. The support member provided at the position to be used is indicated by reference numeral 63A. That is, in the present embodiment, the support member includes the first support member 63A and the second support member 63B. In the following, when it is not necessary to distinguish between the first support member 63A and the second support member 63B, they are simply referred to as the support member 63.

As shown in FIG. 5, the support member 63 is provided so as to project from the opening 60c formed in the frame 60 toward the second tray 51, that is, is provided so as to be able to advance and retreat with respect to the second tray 51. ing. 5, FIG. 8, FIG. 9, and FIG. 11 show a state in which the support member 63 is in the retracted position, and FIG. 10 shows a state in which the support member 63 is in the protruding position. As will be described in detail later, the support member 63 is displaced to the advanced position when the second tray 51 protrudes from the device main body 2, but FIG. 11 shows a state in which the support member 63 is in the retracted position for convenience.

As shown in FIG. 12, the support member 63 is pressed toward the side surface of the second tray 51 by a coil spring 67, which is an example of the pressing means. In the drawings other than FIG. 12, the coil spring 67 is not shown.
When the discharge tray 50 is in the first state, that is, when the second tray 51 is housed in the apparatus main body 2, the support member 63 is in the retracted position and the second tray is due to the spring force of the coil spring 67. It is pressed against the side surface 51d of 51. This situation is shown in FIG.
When the discharge tray 50 switches from the first state to the second state from this state, the second tray 51 comes out of the region facing the support member 63 as shown in the change from FIG. 9 to FIG. 10, and the support member 63 Is switched from the retracted position to the advanced position by the pressing force of the coil spring 67. As shown in FIG. 12, a hook 63d is formed on the support member 63, and the hook 63d is hooked on the back side of the opening 60c (FIG. 5) of the frame 60 to define the advance position of the support member 63. To.

On the contrary, when the discharge tray 50 is switched from the second state to the first state, the second tray 51 pushes the support member 63 against the pressing force of the coil spring 67, so that the support member 63 moves from the advanced position. Switch to the retracted position.
With such a configuration, a configuration in which the support member 63 is displaced can be configured at low cost.
Further, as shown in FIG. 8, the support member 63 presses against the side surface 51d of the second tray 51 when the discharge tray is in the first state, so that the rattling of the discharge tray 50 in the first state is suppressed. it can.

The support member 63 is located in the + Y direction with respect to the end in the + Y direction of the rail 60a, and when the discharge tray 50 is in the second state as shown in FIG. 10, it takes an advance position and takes an advance position to the first tray 52. From below. As a result, the discharge tray 50 in the second state can be stably supported.
Further, since the length of extending the rail 60a shown in FIGS. 5 and 11 in the + Y direction can be suppressed, it is not necessary to form a relief shape in the first tray 52 or the second tray 51, and the cost increases due to the complicated structure. Can be suppressed.

In FIG. 8, the virtual line and the reference numeral M1 form a relief shape, more specifically, a groove, which is required on the side surface 51d of the second tray 51 when the rail 60a is further extended in the + Y direction from the length shown in FIG. Shown. The range Ya shown in FIG. 11 shows an example of the length of extending the rail 60a. If the rail 60a is further extended in the + Y direction from the length shown in FIG. 11, a relief shape as shown by reference numeral M1 in FIG. 8 is required, which may lead to cost increase due to the complication of the structure, and the appearance. Although the above is not preferable, such a problem can be avoided by providing the support member 63 as described above.

The support member 63 is formed with a slope 63c as shown in FIG. The slope 63c is a surface that is pushed by the −Y direction end of the second tray 51 when the discharge tray 50 switches from the second state to the first state. The slope 63c is formed by a surface that intersects the Y direction. With such a slope 63c, the possibility that the second tray 51 is caught on the support member 63 can be suppressed.

Further, since the support members 63 are provided on both sides of the second tray 51, the first tray 52 can be supported more reliably and appropriately. However, the support member 63 may be provided only on one side surface of the second tray 51.

Subsequently, a mechanism for displacing the discharge tray 50 will be described.
The discharge tray 50 is configured to be displaced between the first state and the second state by receiving the power of a motor (not shown), and the convenience of the user is improved. In the present embodiment, the mechanism for displacing the discharge tray 50 is provided at a position facing one side surface of the discharge tray 50, specifically, in the −X direction with respect to the discharge tray 50.
The drive body 64 shown in FIGS. 9 to 11 is driven by a motor (not shown) and constitutes a part of the drive means for driving the discharge tray 50.
The drive body 64 includes two pinion gear portions, and specifically engages with the first pinion portion 66 that meshes with the first rack portion 52a of the first tray 52 and the second rack portion 51a of the second tray 51. A second pinion portion 65 is provided.
Then, as the drive body 64 rotates, the first tray 52 and the second tray 51 are displaced.

More specifically, in FIG. 8 showing the first state of the discharge tray 50, the second pinion portion 65 meshes with the second rack portion 51a of the second tray 51, but the first pinion portion 66 is the first tray 52. It does not mesh with the first rack portion 52a. Therefore, when the drive body 64 starts rotating from the state of FIG. 8, only the second tray 51 starts the displacement operation in the + Y direction at first, and the first tray 52 remains stopped.

After that, when the second tray 51 protrudes by a predetermined amount, the contact portion (not shown) in the second tray 51 comes into contact with the first tray 52, and the first tray 52 is pulled in the + Y direction by the second tray 51, and FIG. As shown in the above, the first rack portion 52a of the first tray 52 meshes with the first pinion portion 66. As a result, the first tray 52 is subsequently driven together with the second tray 51.
After the first tray 52 is driven and displaced by a predetermined amount, the second pinion portion 65 disengages the second tray 51 from the second rack portion 51a as shown in FIG.

On the contrary, when the discharge tray 50 moves from the second state to the first state, the first tray 52 and the first tray are engaged with each other by the first rack portion 52a of the first tray 52 and the first pinion portion 66. The second tray 51 supported by the 52 is displaced in the −Y direction. Eventually, the second pinion portion 65 meshes with the second rack portion 51a of the second tray 51, and then the first pinion portion 66 disengages from the first rack portion 52a of the first tray 52. As a result, the second tray 51 is continuously displaced in the −Y direction, and returns to the first state of the discharge tray 50 shown in FIG.

In the present embodiment, the second state of the discharge tray 50 includes a first position shown in FIG. 3 and a second position further protruding from the first position as shown in FIG. The first position is, for example, a position when the A4 size paper is ejected so that the longitudinal direction is along the Y-axis direction, and the second position is, for example, the A3 size paper is ejected so as to be ejected along the Y-axis direction. The position of the case. The control unit (not shown) that controls the fourth motor (not shown), which is the power source of the discharge tray 50, positions the discharge tray 50 based on the paper size information obtained from the driver information.

As described above, the support member 63 is located on both sides of the second tray 51 on the side opposite to the side on which the drive body 64 is provided and the side on which the first support member 63A is provided. The second support member 63B and the like are included. In this configuration, the coil spring 67 (see FIG. 12) that presses each support member may be different between the coil spring that presses the first support member 63A and the coil spring that presses the second support member 63B. .. Specifically, a coil spring that presses the second support member 63B is used that exerts a stronger spring force than the coil spring that presses the first support member 63A, and when the discharge tray 50 is in the first state, the first state is adopted. The two trays 51 are configured to be pressed toward the drive body 64 (see FIG. 8). As a result, the engagement between the second rack portion 51a provided on the second tray 51 and the second pinion portion 65 can be appropriately maintained.

The present invention is not limited to the embodiments described above, and various modifications can be made within the scope of the invention described in the claims, and these are also included in the scope of the present invention. Needless to say.
For example, the support member 63 may be configured to move forward and backward by an actuator such as a motor or a solenoid. In that case, it is preferable to provide a sensor that detects the positions of the first tray 52 and the second tray 51.
