FIG. 1 is a perspective view of a drive section showing one embodiment of the present invention, and FIG.
The figure is a front view of the printer device.

First, the outline of the apparatus will be explained with reference to FIG.

A paper feed case 3 capable of storing a plurality of recording papers 2 is disposed at a portion of the lower part of the housing 1 that is offset to the right when viewed from the front panel 1a side. , a paper ejection case 4 into which the printed recording paper 2 is sent.
is installed. Further, a printing unit 5 is provided on one side of the housing 1 opposite to the side where the paper feed and paper ejection cases 3.4 are disposed, and the recording paper in the paper feed case 3 is provided with a printing unit 5. 2
is fed to this printing section 5 and is printed by the printing section 5.

That is, there is an opening 3a on the printing section 5 side of the upper part of the paper feed case 3.
A paper feed roller 6, which is an example of a conveying device, is disposed opposite the opening 3a, and a hole is formed in the bottom of the paper feed case 3, and a paper feed roller 6 is provided through the hole. A lever 31 that can be rotated is inserted into the paper feed case 3.

Then, by the rotation of this lever 31, the recording paper 2 stored in the paper feed case 3 is lifted toward the opening 3a, and is pressed against the paper feed roller 6 with a predetermined pressure so as to be able to come into contact with and separate from it. It looks like this. When the paper feed roller 6 is rotated, the recording paper 2 in contact with the paper feed roller 6 is fed to the printing section 5 through the opening 3a, and a platen disposed in the printing section 5 is fed to the printing section 5. It is located between the roller 7 and the ink ribbon 8, and is configured to perform printing by transferring the ink of the re-ink ribbon 8 by the heat of the thermal head 9.

Further, a guide 11 for guiding the recording paper 2 toward the paper ejection case 4 is provided in the printing section 5, and a paper ejection roller 12 is provided on the paper ejection case 4 side of this guide 11. The recording paper 2 on which printing has been completed is fed into the paper ejection case 4 by the action of the guide 11 and the paper ejection roller 2, and is placed on the bottom surface of the paper ejection case 4.

Further, the front panel 1a side of this paper ejection case 4 is released, and this released portion faces an opening 1b formed in the front panel 1a with a width equal to or greater than the length of the recording paper 2. . Further, a discharge member 13 is provided in the paper discharge case 4 and is configured to be able to slide along the bottom surface in the direction of the opening 1b, so that the recording paper 2 in the paper discharge case 4 is ejected. It is configured to be discharged through the opening 1b by being pressed toward the opening 1b by the member 13.

By the way, as shown in FIG. 1, the paper feed roller 6 is mounted on a shaft 6a. The shut 6a is supported by the housing 1 via a bearing (not shown), and a gear 14 is mounted on the end of the shaft 6a opposite to the front panel 1a. Further, a motor 15 as a drive source is disposed within the housing 1, and a drive gear 16 mounted on an output shaft 15a of the motor 15 is connected to the gear 14.
is engaged with. The motor 15 is configured as a DC motor, for example, and is capable of forward and reverse rotation, and the output shaft 15a rotates in the direction shown by the solid arrow in FIG.
Normal rotation), the paper feed row 56 is set to be rotated in a direction to feed the recording paper 2 toward the printing section 5.

Further, a gear 17 is engaged with the gear 14 and is rotatably mounted on a shaft (not shown).

A hevel gear 18a is integrally formed on the front panel 1a side of this gear 17, and this bevel gear 18a is connected to another bevel gear 18b disposed near the discharge member 13.
is engaged with. Further, the bevel gear 18b is connected to a gear 19 arranged to rotate in a plane parallel to the bottom surface of the paper ejection case 4 via a clutch device 20 such as a friction clutch. Therefore, when the rotation of the gear 19 is stopped by a predetermined force, the clutch device! 20 allows the gear 17 to idle.

On the other hand, a rack 13a is provided on the gear 19 side of the discharge member 13.
is formed, and this rack 13a and gear 19 are meshed. Therefore, when the motor 15 is rotated in the normal direction, the ejection member 13 is urged in a direction to separate from the front panel 1a, while when the motor 15 is rotated in the reverse direction, the ejection member 13 is pushed into the opening of the front panel 1a. It is moved to the 1b side.

A long hole 22 is formed in the discharge member 13 in the moving direction of the discharge section 013, and a pair of bins 23a and 23b protruding from the housing 1 are slidably inserted into the long hole 22. When the discharge member 13 is moved, it is guided by the bins 238, 23b.

Further, a pressing surface 24 is formed upright on the front panel 1a side of the ejecting member 13, and the recording paper 2 placed on the bottom surface of the paper ejecting case 4 is pressed by this pressing surface 24. , the recording paper 2 is ejected to the outside of the housing 1 through the opening 1b of the front panel 1a. Therefore, when the discharge member 13 is moved toward the front panel 1a and the bin 23a provided on the front panel 1a is brought into contact with one side of the elongated hole 22 and stopped, the pressing surface 24 is When the recording paper 2 is fed into the paper ejection case 4, it is set to be located further into the inner part of the housing 1 than one end of the recording paper 2.

Next, the operation of the embodiment having the above-mentioned configuration will be explained.

When the printer is in a standby state, the discharge member 13 is moved to the side away from the front panel 1a, and is stopped when the bin 23a on the front panel 1a side comes into contact with one end of the elongated hole 22.

When a print switch (not shown) is pressed in this state, the lever 31 is raised by a driving source (not shown), and the recording paper 2 housed in the paper feed case 3 is pressed against the paper feed roller 6 with a predetermined pressure. Pressed.

At about the same time, the output shaft 15a of the motor 5 is connected to the first output shaft 15a.
It is rotated forward in the direction shown by the solid arrow in the figure. Then, the rotation of the gear 16 is transmitted to the gear 14, and the shaft 6a
The paper feed roller 6 is rotated via. Then, the recording paper 2 that is in contact with the paper feed roller 6 is moved by friction and is fed to the printing section 5 through the opening 3a of the paper feed case 3.

The recording paper 2 is placed between the platen roller 7 and the ink ribbon 8 of the printing unit 5, and the ink of the ink ribbon 8 is transferred by the heat of the thermal head 9, thereby printing. Note that the contact between the paper feed roller 6 and the recording paper 2 in the paper supply case 3 is released by lowering the lever 31 by another driving source after one recording paper is supplied to the printing section 5. .

The recording paper 2 on which printing has been completed is guided by a guide 11, and fed into the paper ejection case 4 by a paper ejection roller 12 as shown in FIG. 3, and the paper is ejected as shown in FIG. case 4
, and one end thereof faces the pressing surface 24 of the ejection member 13 disposed inside the paper ejection case 4 .

The motor 15 is then reversely rotated in the direction indicated by the dashed arrow 0 in FIG. This reversal is caused by an ejection detection element 32 (for example, having a light receiving and emitting part) that detects the ejection (passage) of the recording paper 2, which is provided between the guide 11 and the paper ejection roller 12, and when the recording paper 2 passes, the reflection is reflected on the paper surface. This is based on the detection output from a light-receiving section that receives light from a light-emitting section. This rotation is transmitted to the gear 17 via the gear 14, and the rotation of the gear 17 is further transmitted to the gear 19 via the bevel gears 18a, 18b and the clutch device 20.
and the gear 19 is rotated in the direction of the dashed arrow. Since this gear 19 is meshed with a rack 13a formed on the ejection member 13, when this gear 19 is rotated, the ejection member 13 is moved toward the front panel 1a via the rack 13a.

Then, the pressing surface 24 of the ejection member 13 presses against the recording paper 2.
As the ejection member 13 slides, the recording paper 2 is moved toward the opening 1b of the front panel 1a, and as shown in FIG. 2 is discharged 1 from the housing 1. Further, the discharge member 13 is connected to the front panel 1.
The bottle 23b, which is provided on the side away from a, comes into contact with one end of the elongated hole 22, and is stopped. In this case, even if the motor 15 continues to rotate with the bin 22b and the long hole 22 in contact with each other, the discharge member 13 is stopped by the bin 23a, so the clutch device 20 acts to shift the gear 1.
The motor 15 will not be adversely affected by the idling of the motor 7.

When the ejection of the recording paper 2 is completed, the motor 15 starts to rotate normally, and the ejection member 13 is moved from the front panel until the bin 23a comes into contact with one side of the elongated hole 22 due to an action opposite to that described above. By being moved in the direction away from 1a, this discharge member 13 returns to the standby state. In this case as well, the action of the clutch device 20 does not have any adverse effect on the motor 15. Furthermore, as described above, since the recording paper 2 in the paper feed case 3 is separated from the paper feed roller 6, the recording paper 2 is not fed to the printing section 5 even if the motor 15 rotates forward. After the ejection member 13 returns to the holding state and the motor 15 is stopped, the recording paper 2 in the paper feed case 3 is pressed with a predetermined pressure against the paper feeding [I-ra 6] and returns to the standby state. .

In this embodiment, an example in which a DC motor is used as an example of the drive source has been described, but this drive source may also be configured as, for example, a pulse motor. Furthermore, the clutch device interposed between the gear 19 and the bevel gear 18b is not limited to a friction clutch, but may also be configured as a one-way clutch, for example.

[Effects of the Invention] As explained above, according to the printer device of the present invention,
Since a single drive source can perform both operations of supplying the recording paper to the printing section and discharging it from the housing, the configuration is simple and prevents the device from becoming larger and increasing in price. This makes maintenance easier.
