Abstract

PROBLEM TO BE SOLVED: To correct slack of a recording medium by controlling the printing operation depending on the rotational amount of a travel roller and disposing a recording medium retaining roller having same width as the print width of a recording means in front of the recording means in the printing direction. SOLUTION: A travel roller 20 and a paper retaining roller 21 are disposed rotatably about axes 20a, 21a, respectively. The travel roller 20 rotates to transmit the rotating force of a pulley 9 to an encoder 11. The paper retaining roller 21 is disposed in front of a recording head 5 in the printing direction thereof and wider than the print width of the recording head 5. The travel roller 20 touches a recording medium P on the outside of the print region of the recording head 5. When being operated manually in the direction shown by an arrow, the paper retaining roller 21 moves on the recording medium P while retaining the recording medium P. More specifically, when the recording medium P is slackened, the paper retaining roller 21 retains the recording medium P and corrects the slack.

The operation of the manual type printing apparatus 1 having the above-mentioned configuration will be described. When the apparatus 1 is manually operated in the direction of the arrow in FIG.
It moves on the recording medium P. Thus, even if the recording medium P is loose, the paper pressing roller 21 presses the recording medium P to correct the slack. Therefore, since the head gap is kept constant, a stable printing operation can be performed.

Next, another embodiment of the manual printing apparatus according to the present invention will be described with reference to FIG. FIG.
(A) is a side sectional view showing an internal configuration near a contact surface of a manual type printing device having a roller for holding a recording medium at a lower end of a body portion, and (b) is a printing direction near a contact surface of the device. FIG. Body part 2 of manual type printing device 25
At the lower end of 6 and in front of the recording head 5, a plurality of paper pressing rollers 28 divided at right angles to the printing direction by the recording head 5 are provided at regular intervals.

When the manual printing device 25 is moved in the direction of the arrow in FIG. 5A, the recording medium P is pressed by the paper pressing roller 28, and the slack is corrected. This allows
Since the head gap is kept constant, a stable printing operation can be performed.

The present embodiment is not limited to the configuration shown in FIG. 5, and various modifications are possible. For example, the manual printing device 25 has a paper pressing roller 28, which corrects the slack generated in the recording medium P.
The lower end of the body portion is configured to be in contact with the recording medium P, and the lower end of the body portion may correct slack generated in the recording medium P. In this case, the lower end of the body portion may be formed of a material such as a resin having good slidability.

Next, still another embodiment of the manual printing apparatus according to the present invention will be described with reference to FIGS. FIG. 6 is a side cross-sectional view showing the internal configuration near the contact surface of a manual type printing apparatus having two paper pressing rollers near the lower end of a recording head capable of bidirectional printing, FIG.
Is a sectional view of the vicinity of a contact surface when the apparatus is viewed from a printing direction, and FIG. 8 is a bottom view of the apparatus. Two running rollers 20 are provided on both sides of the lower end of the body portion 32 of the manual printing device 31.
33 is provided to maintain the posture of the body portion 32. Two paper pressing rollers (rollers for pressing a recording medium) located near the lower end of the recording head 5
A movable piece (inclined member) 34 having 35a and 35b is provided on the body 32 so as to be rotatable about a shaft 34a. The paper pressing rollers 35a and 35b are located on the front side and the rear side of the recording head 5, respectively, have a width equal to or larger than the printing width of the recording head 5, and according to the traveling direction of the apparatus 31, the recording head 5, the roller on the front side in the printing direction is in contact with the recording medium. As a mechanism therefor, in the vicinity of the lower end of the recording head 5, a sliding wheel (power transmission mechanism) 37 that slides and rotates by receiving a force in the rotational direction of the traveling roller 20 is rotatable about the shaft 37a on the body 32. The sliding wheel 37 is also in contact with the movable piece 34, and is configured to tilt one end of the movable piece 34 in accordance with the rotation of the sliding wheel 37.

Here, the traveling roller 20 of the slip wheel 37 is used.
A mechanism for transmitting the power from the movable piece 34 to the movable piece 34 will be described with reference to FIG. FIG. 9 shows the paper pressing rollers 35a, 35 when the manual printing device 31 is manually scanned on the recording medium P.
It is a figure for explaining a situation of 5b. As shown in FIG. 9A, when the device 31 is moved in the direction of the white arrow (rightward), the traveling roller 20 rotates clockwise. Receiving the rotational force of the traveling roller 20, the slide wheel 37 slides and rotates counterclockwise about the shaft 37a. The movable piece 34 is tilted about the shaft 34a by the frictional force generated between the slide wheel 37 and the movable piece 34, and the paper pressing roller 35b is pushed up. Thereby, the recording head 5
The paper pressing roller 35a located in front of the printing direction contacts the recording medium P. Further, as shown in FIG. 9B, when the device 31 is moved in the direction of the outline arrow (left direction), the traveling roller 20 rotates counterclockwise. Receiving the rotational force of the traveling roller 20, the sliding wheel 37 slides and rotates clockwise about the shaft 37a. As a result, the paper pressing roller 35b side of the movable piece 34 is pressed down, and the paper pressing roller 35b located in front of the recording head 5 in the printing direction.
Contacts the recording medium P.

As described above, the paper pressing rollers 35a and 35b positioned in front of the recording head 5 in the printing direction come into contact with the recording medium P, press the recording medium P, and correct the slack of the recording medium P. Even if the apparatus is manually scanned in any direction, a stable printing operation can be performed. Further, since the paper pressing rollers 35a and 35b positioned rearward of the recording head 5 in the printing direction do not come into contact with the recording medium P, the characters and the like printed on the recording medium P by the recording head 5 may be stained. Absent.

[0023]

As described above, according to the manual printing apparatus according to the first aspect of the present invention, the recording head has a width equal to the printing width of the recording head ahead of the recording head in the printing direction. Since the paper holding roller that runs on the medium is provided, even if the recording medium has become loose, it can be corrected. As a result, the head gap is kept constant, so that a stable printing operation can be performed.

According to a second aspect of the present invention, in addition to the above-described effects, the paper presser positioned forward of the recording head in the printing direction in accordance with the running direction of the apparatus. Since the printing roller contacts the recording medium and presses the recording medium, it is possible to correct the slack of the recording medium in any printing direction, maintain a constant head gap, and perform a stable printing operation. Further, since the paper pressing roller positioned rearward of the recording head in the printing direction does not contact the recording medium, characters printed on the recording medium by the recording head are not stained.

According to the manual printing apparatus of the third aspect of the present invention, in addition to the above-mentioned effects, since the ink-jet type recording means is used, the recording of the wire dot type using a printing ribbon or the like is possible. The configuration is simpler than the means, and the entire apparatus can be reduced in size.
