The rotating shaft 5a is biased by a pinch roller spring 19, which is a biasing means described later, provided between the insertion port 3a and the pinch roller and below the conveyance path 18 of the recording sheet 1. The configuration is such that the pinch roller 5 is brought into pressure contact with the conveying roller 4.

In addition, in FIG. 2, 26 indicates a screw 2 on the side of the frame 3.

If the width of the recording sheet 1 is H, then there is a relationship of G≧F≧H.

Therefore, the bent piece 19b can guide the recording sheet 1 in the width direction when the recording sheet 1 is conveyed, and can also prevent the side wall of the frame 3 from being scraped by the edge portion of the recording sheet 1.

Next, the carriage 7 is used to mount the recording head 9 and move it back and forth in the width direction of the recording sheet 1.

As shown in FIG. 4, a screw groove 13d is bored in the outer peripheral surface of the lead screw 13, and a bottle 7a protruding from the carriage 7 is inserted into the screw groove 13d. Therefore, as the lead screw 13 rotates forward and backward, the pin 7a inserted into the screw groove 13d also moves along the screw groove 13d, and the carriage 7 moves toward the guide shaft 8 in the direction of the arrows ■ and J in the figure. is configured to move along the

Further, the protrusion 31 and the locking member 20 are provided not only on the left and right side surfaces of the frame 3, but also on the back side of the frame 3 (the side opposite to the carriage 7) shown in FIG. 1, close to the bottom surface. . As shown in FIG. 8, each of the locking members 20 fixes the recording apparatus C by being held by a pressing member 20a provided correspondingly to the main body of the apparatus.

Further, as shown in FIG. 5, a groove 7a is provided in a part of the carrier and shifter, and a wall 3j hanging vertically from the frame 3 engages with this groove 7a. Like the guide shaft 8, it guides the movement of the carriage 7.

Further, 21 is a switch for detecting the home position (recording standby position) of the carriage 7, which detects that the end 7b of the carriage 7 is at its home position by moving and pressing the switch 21. be.

The switch 21, like the step motor 10, is connected to a control circuit (not shown).

Next, as shown in FIG. 1, the recording head 9 is mounted on the carriage 7 and records an ink image on the recording sheet 1 conveyed by the conveyance roller 4 and the pinch roller 5 while moving in the width direction. It is. The recording head 9 is
It is connected to a flexible circuit board 22 for transmitting control signals corresponding to image information from a control circuit (not shown). Further, 23 is a set lever for electrically connecting the recording head 9 and the flexible circuit board 22.

As the recording head 9, an inkjet recording method is suitably used.

The inkjet recording method includes a liquid ejection port for ejecting recording ink liquid as flying droplets, a liquid flow path communicating with the ejection port, and a part of this liquid flow path. and ejection energy generating means for providing ejection energy for forming flying droplets in the ink liquid. The ejection energy generating means is then driven in accordance with the image signal to eject ink droplets to create an image.

Examples of the ejection energy generating means include a method using pressure energy generating means such as an electromechanical transducer such as a piezo element, and an electromagnetic energy generating means that generates flying droplets by irradiating and absorbing T4 magnetic waves such as a laser into the ink liquid. There are a method using a thermal energy generating means such as an electrothermal converter, and a method using a thermal energy generating means such as an electrothermal converter. Among these methods, a method using a thermal energy generating means such as an electrothermal converter is preferable because it allows the ejection ports to be arranged in a high density manner and also enables the recording head to be made compact.

In this embodiment, a bubble jet recording method, which is one of the inkjet recording methods, is used as the recording means.

FIG. 6 is an explanatory diagram of the configuration of the recording head 9 constituting the recording means, and FIGS. 7(a) to (6) are explanatory diagrams of the bubble jet recording method.

In FIG. 6, 9a is a heater board, and an electrothermal converter (discharge heater) 9b and an electrode 9c made of aluminum or the like for supplying power to this are formed and arranged on a silicon substrate. . A top plate 9e having a partition wall for partitioning a liquid path (nozzle) 9d for recording liquid is adhered to the heater board 9a. Further, the recording head 9 includes an ink storage chamber 9f for supplying ink to the nozzle 9e. That is, the recording head 9 is of a disposable type, and the recording head 9 is replaced when the ink in the ink storage chamber 9f runs out.

The ink supplied from the ink cartridge 9f is
It is guided into each nozzle 9d. Ink discharge ports 9dl are formed in these nozzles 9d, and the discharge ports 9dl are formed in these nozzles 9d.
dl are formed facing the recording sheet 1 of the recording head 9 at a predetermined pitch in the sheet conveyance direction (vertical direction in FIG. 6).

Here, the principle of ink flying in the bubble jet recording method will be explained with reference to FIGS. 7(a) to 7(a).

In a steady state, as shown in FIG. 7(a), the surface tension and external pressure of the ink 24 filled in the nozzle 9d are balanced at the ejection port. When the ink 24 is to be ejected in this state, the electrothermal converter 9b in the nozzle 9d is energized to cause the ink 24 in the nozzle 9d to undergo a rapid temperature rise beyond nucleate boiling. Then, as shown in FIG. 7(b), the ink 24 adjacent to the electrothermal converter 9b is heated to generate microbubbles, and the ink in the heated portion is vaporized to cause film boiling. As shown in FIG. 7 (C1), the bubbles 25 grow quickly.

When the bubbles 25 grow to the maximum as shown in FIG. 7(d), ink droplets are pushed out from the ejection opening in the nozzle 9d, and the ink droplets fly onto the recording sheet 1 at that speed to record an ink image. It is something to do.

When the electricity supply to the electrothermal converter 9b is finished, the state shown in FIG. 7 (el
As shown in Figure 7, the grown bubbles 25 are cooled and contracted by the ink 24 in the nozzle 9d, and further, as shown in Figure 7), the ink contacts the surface of the electrothermal converter 9b and is rapidly cooled. The bubble 25 disappears or shrinks to an almost negligible volume. Then, when the bubble 23 contracts,
As shown in FIG. 7(g), ink is supplied from the ink storage chamber 9f into the nozzle 9d by capillary action in preparation for the next energization.

Therefore, an ink image is recorded on the recording sheet 1 by energizing the electrothermal transducer 9b in synchronization with the movement of the carriage 7 in accordance with image information.

Next, the recording operation of the recording apparatus C configured as described above will be explained.

When a drive signal is input from a control circuit (not shown), the step motor 10 is rotationally driven in a predetermined direction. This causes the motor gear 11. The driving force is transmitted to the transmission gear 12 via the sheet conveyance transmission gear 13a, and the lead screw 13 rotates in the direction of the arrow in FIG. At this time, the carriage 7 is moved in the direction of arrow 1 in the figure by the pin 7a inserted into the screw groove 13d. Then, the carriage 7 moves a predetermined amount, and the end portion 7b turns the detection switch 21 into the
N and check the home position of the carriage 7.

When the home position of the carriage 7 is confirmed, the step motor 10 is driven to rotate in the reverse direction, and the lead screw 13 is rotated in the direction of the arrow in FIG. Move it in the direction of arrow J. At this time, recording is performed on the recording sheet 1 by selectively applying a signal corresponding to the image information to the recording head 9.

At this time, the rotation of the lead screw 13 in the direction of the arrow is transmitted to the clutch gear 15 via the sheet conveyance transmission gear 13b and the sheet conveyance intermediate gear 14, and the rotation of the lead screw 13 is transmitted to the clutch gear 15 in the direction of the arrow M in FIG. Rotate and drive.

However, since the clutch spring 17 wound around the rotating shaft 4a of the conveying roller 4 rotates in a loosening direction, the rotational force is not transmitted to the rotating shaft 4a, so the conveying roller 4 does not rotate and the recording sheet 1 is not conveyed.

Next, when a portion of recording is completed on recording sheet 1,
The step motor 10 is driven to rotate in the opposite direction again, and the lead screw 13 is rotated in the direction of the arrow through the gear train.
The carriage 7 is moved to the home position in the direction of arrow 1.

At this time, the rotation of the lead screw 13 in the direction of the arrow is caused by the sheet conveyance transmission gear 13b and the sheet a conveyance intermediate gear 1.
4 to the clutch gear 15, and drives the clutch gear 15 to rotate in the direction of arrow N in FIG. Therefore, the clutch spring 17 wound around the rotating shaft 4a of the conveying roller 4 rotates in the direction of tightening, so the rotational force is transmitted to the rotating shaft 4a, the conveying roller 4 is rotated, and the recording sheet 1 is conveyed by a predetermined amount. .

In the series of recording operations described above, arrow 1.
By keeping the amount of movement in the J direction constant, recording sheet 1
It becomes possible to convey a certain amount of

Next, the operation of the guide shaft 8 and the locking member 20 during the recording operation will be described with reference to FIGS. 12(a) and 12(b).

FIG. 12(a) shows the carriage 7 moving in the direction of the arrow ■, and FIG. 12(b) shows the carriage 7 moving in the direction of the arrow J.

When the carriage 7 moves in the {circle around (2)} direction or the J direction in FIGS. 12(a) and 12(b), the guide shaft 8 receives a force in the one direction or the J direction due to the frictional force with the carriage 7, respectively. As a result, the guide shaft 8 moves in the thrust direction within the through hole 3h, but the receiving member 20 whose end face is elastic prevents the guide shaft 8 from moving, thereby absorbing rattling.

Therefore, it is possible to reduce noise caused by rattling in the guide shaft 8 when the carriage 7 moves.

C Other Embodiments] Next, the pinch roller spring 19 applied to the recording device C
Another embodiment will be described with reference to FIGS. 13 and 14.

In FIG. 13, in this embodiment, the bent piece 19b of the pinch roller spring 19 is made narrower toward the downstream side in the conveying direction of the recording sheet 1. At this time, the bent piece 19b
The interval F' on the downstream side of is configured to be wider than at least the width H of the recording sheet 1.

Next, in FIG. 14, this embodiment shows the pinch roller spring 1.
The end portion 19d of the bent piece 19b of No. 9 is bent in the direction away from the recording sheet 1 (outward direction). The end portion 29d is bent so that the upstream edge portion 19e of the bent piece 19b is shortened.

According to each of the above configurations, when the recording sheet 1 is inserted, the folding piece 1
By preventing the recording sheet 1 from getting caught on the upstream edge 19e of the recording sheet 9b, smooth conveyance can be achieved.

Furthermore, the configuration of the recording means applied to the above embodiments is as follows:
In addition to the above-mentioned combination of the discharge port and the liquid path 7 electrothermal converter, U.S. Pat.
It is also possible to employ those disclosed in the specification of No. 58333, Japanese Unexamined Patent Publication No. 59-123670, and the like.

The recording means described above is a disposable type recording head in which an ink storage chamber 9f is provided in the recording head 9, and the recording head 9 is replaced when the ink in the ink storage chamber 9f runs out. However, ink may be supplied to the recording head from an ink cartridge separately installed in the recording apparatus.

Furthermore, the recording means of the present invention need not be limited to the bubble jet recording method described above. For example, there is a so-called thermal transfer recording method in which an ink sheet coated with heat-melting ink is heated in accordance with an image signal and the molten ink is transferred to the recording sheet 1, and a so-called thermal transfer recording method in which the recording sheet 1, which develops color by heat, is heated in accordance with the image signal. Various recording methods can be employed, such as a thermal recording method and a so-called wire don't recording method in which recording is performed by striking an ink ribbon with a wire according to an image signal.

Therefore, the recording head is not limited to the above-mentioned bubble agent head, and for example, a thermal head, a wire dot head, a daisy-wheel head, etc. can be used.

The recording device may be used as an image output terminal for information processing equipment such as a computer, and may also be applied to a copying device combined with a reader or the like, or even a facsimile device having a sending/receiving function. It is possible.

<Effects of the Invention> As described above, in the present invention, a part of the biasing member that presses the driven rotor against the transport rotor is made to protrude into the transport path of the recording medium at least wider than the recording medium. By guiding in the width direction during transportation, it is possible to prevent the frame side wall of the apparatus main body from being scraped at low cost and with good workability.
