It is easy to control in production and handling, and a common mold may be used for molding. Also, since the hopper cassettes 27 and 28 are interchangeable, even if one of the hopper cassettes or a part of the drive transmission system or the like breaks down, the hopper cassettes 27 and 28 can be used.
Can be dealt with by replacing each other.

In this embodiment, the number of hopper cassettes is two, but the number of hopper cassettes may be three or more if necessary. Further, in order to identify the hopper cassette according to the type of the built-in medium, an identification means (not shown) may be provided in the hopper cassette or the main body. Second Embodiment FIG. 2 is a simplified explanatory diagram of the present embodiment. FIG. 2A is a side view showing a case where the motor rotates counterclockwise,
(B) is a side view showing a case where the motor rotates clockwise.

In the figure, reference numeral 31 denotes a main body of the medium processing apparatus of the present embodiment. Reference numerals 32 and 33 denote hopper cassettes of the present embodiment, in which the media 4 and 5 are stored, respectively. Since the hopper cassettes 32 and 33 have the same type and the same function, they are interchangeable. Reference numeral 29 denotes a tray of the present embodiment, on which the hopper cassettes 32 and 33 can be placed side by side in the pull-out direction. Since the inner part of the tray 29 and the part on the drawing direction side are formed so as to be stepped, the hopper cassette 33 is arranged higher than the hopper cassette 32.

The tray 29 has a drawer structure. When replenishing the hopper cassettes 32 and 33 with the media 4 and 5, the tray 29 is pulled out in the direction of arrow A, and
To reload the hopper cassettes 32 and 33 into the main body 31, the tray 29 is pushed in the direction of arrow B. Reference numerals 34, 35, and 36 denote idle gears of the present embodiment, which sequentially transmit the driving force of a motor (not shown) as a driving source via a motor gear 9, and rotate the power transfer gear 12.

The rotation of a motor (not shown) is transmitted to a power transfer gear 11 via a motor gear 9. Power transfer gear 1
1 and 12 transmit power to hopper cassettes 32 and 33, respectively. The motor (not shown), the motor gear 9, the idle gears 34, 35 and 36, and the power transfer gears 11 and 12 are installed on the main body 31 side, and constitute a drive transmission system 37 of this embodiment.

The power from the drive transmission system 37 on the main body 31 side is transmitted to the hopper cassettes 32 and 33 to feed out the media 4 and 5. With the tray 29 stored in the main body 31, the power transfer gears 11 and 12 of the drive transmission system 37 and the power receiving gears 14 and 15 of the hopper cassettes 32 and 33 are engaged with each other.

Reference numerals 16 and 17 denote feed rollers.
When the media 4 and 5 are fed out, they are integrated with the power receiving gears 14 and 15, respectively, and come into pressure contact with the media 4 and 5. Reference numerals 18 and 19 denote idle gears which mesh with the power receiving gears 14 and 15, respectively. The idle gears 18 and 19 are engaged with gears 20 and 21 for pickup rollers, respectively.

Numerals 38 and 39 denote pickup rollers of this embodiment, which are gears 20 and 2 for pickup rollers.
The pickup rollers 38 and 39 are one-way mechanisms that rotate only in the counterclockwise direction. As shown in FIG. 2A, when the motor gear 9 rotates counterclockwise by a motor (not shown), the pickup roller gear 20 also rotates counterclockwise, so that the pickup roller 38 also rotates counterclockwise. However, since the pickup roller gear 21 rotates clockwise, the pickup roller 39 does not rotate due to the operation of the one-way mechanism. As a result, the medium 4 is fed, but the medium 5 is not fed.

Conversely, as shown in FIG. 2B, when the motor gear 9 rotates clockwise by a motor (not shown), the pickup roller gear 21 rotates counterclockwise, so that the pickup roller 39 also rotates. Although it rotates counterclockwise, the pickup roller gear 20 rotates clockwise, so that the pickup roller 38 does not rotate.
As a result, the medium 5 is fed, but the medium 4 is not fed.

Reference numerals 24 and 25 are reverse rollers.
This is to prevent the feed rollers 16 and 17 from feeding out two or more media at a time.
Although no power is supplied to the reverse rollers 24 and 25, the reverse rollers 24 and 25 have a one-way mechanism and rotate only in a counterclockwise direction. That is, media 4 and 5
Is rotated so as to return downward, but does not rotate so as to be extended upward. Therefore, when the feed rollers 16 and 17 send out the media 4 and 5, two or more sheets are prevented from being extended. Will work.

The portion of the drive transmission system 37 corresponding to the hopper cassette 33 is arranged higher than the portion corresponding to the hopper cassette 32, and when the tray 29 is pulled out, the operation of the hopper cassette 32 on the tray 29 is obstructed. It does not become. Since the drive transmission system 37 is displaced in the vertical direction, there is no need to displace it in the horizontal direction. Therefore, even if the hopper cassettes 32 and 33 are of the same type, the feed rollers 16 and 17 are arranged in a straight line,
The media 4 and 5 can be sent to a transport path (not shown).

The operation will be described below. The portion of the drive transmission system 37 corresponding to the hopper cassette 33 is the hopper cassette 3
Since the tray 29 is arranged higher than the portion corresponding to 2, the trays 29 can be pulled out in the direction of arrow A to replenish the media 4 and 5 to the hopper cassettes 32 and 33. Next, the tray 29 is loaded again in the direction of arrow B. Thereby, the power transfer gears 11 and 12 of the drive transmission system 37 are
And the power receiving gears 14 and 15 of the hopper cassettes 32 and 33 are meshed with each other and interlock.

When a motor (not shown) is rotated in a counterclockwise direction, the rotation is transmitted to the power transfer gear 11 via the motor gear 9 to rotate the power receiving gear 14. Since this rotation rotates the pickup roller gear 20 counterclockwise through the idle gear 18, the pickup roller 38 also rotates counterclockwise to feed out the medium 4.

The rotation of the motor (not shown) in the counterclockwise direction is sequentially transmitted to the idle gears 34, 35 and 36 via the motor gear 9 to rotate the power transfer gear 12. The rotation of the power transfer gear 12 is transmitted via the power receiving gear 15 and the idle gear 19 to rotate the pickup roller gear 21 clockwise, but this rotation is transmitted to the pickup roller 39 by the function of the one-way mechanism. Since there is no medium, the medium 5 is not fed out.

When a motor (not shown) is rotated clockwise, the rotation is sequentially transmitted to idle gears 34, 35 and 36 via motor gear 9 to rotate power transfer gear 12. The rotation of the power transfer gear 12 is transmitted via the power receiving gear 15 and the idle gear 19 and rotates the pickup roller gear 21 counterclockwise, so that the pickup roller 39 also rotates counterclockwise to feed out the medium 5. .

The clockwise rotation of the motor (not shown) is transmitted to the power transfer gear 11 via the motor gear 9 and the pickup roller gear 20 is rotated clockwise via the power receiving gear 14 and the idle gear 18. , The pickup roller 38 by the function of the one-way mechanism
Does not rotate, so that the medium 4 is not fed out. As the power receiving gears 14 and 15 rotate, the feed rollers 16 and 17 also rotate. The fed medium 4
Or 5 is sandwiched between the feed roller 16 or 17 and the reverse roller 24 or 25,
By rotation of 6 or 17, the sheet is sent to a not-shown conveyance path.

In this embodiment, the one-way mechanism is described as being provided on the pickup roller. However, the one-way mechanism may be provided on any part such as the gear for the pickup roller or the idle gear depending on the rotation direction of the motor. Can be selectively fed out. As described above, even if the hopper cassettes 32 and 33 have the same shape, the drive transmission system 37 is arranged so as not to interfere when the hopper cassette 32 is pulled out. Can be easily managed, and a common mold may be used for molding.

Since the hopper cassettes 32 and 33 are interchangeable, even if one of the hopper cassettes or a part of the drive transmission system or the like fails, the hopper cassettes 3 and 33 can be used.
This can be accommodated by replacing 2 and 33 with each other. Further, since the media 4 and 5 can be fed from the two hopper cassettes 32 and 33 per motor, the cost can be reduced.

In the present embodiment, the number of hopper cassettes is two, but the number of hopper cassettes may be three or more if necessary. Further, in order to identify the hopper cassette according to the type of the built-in medium, an identification means (not shown) may be provided in the hopper cassette, the main body, or the like.

[0042]

As described above in detail, even if the hopper cassettes have the same shape, the drive transmission system is arranged so as not to interfere when the hopper cassette is pulled out, so that the hopper cassette can be made compatible. This makes it easy to control the production and handling, and the use of a common mold during molding makes it possible to reduce the cost.

Also, in the event that one of the hopper cassettes or a part of the drive transmission system or the like breaks down, it is possible to respond by replacing the hopper cassettes. In addition, when the medium can be fed out from a plurality of hopper cassettes by one motor, the cost can be further reduced.
