is formed. Sprocket guide arm 1
One end of sub-arms 22L, 22R is fixed to the other ends of sub-arms 1L, 11R in a manner perpendicular to the longitudinal direction thereof, and these sprocket guide arms 11L, 1
1R and the sub-arms 22L, 22R are configured to be rotatable around the shaft 13, and the sub-arms 22L, 22R
Pins 25L and 25R are planted at the other end, and wire springs 24L and 2 are attached to these pins 25L and 25R.
One end of 4R is locked, and the other end is locked to pins 23L and 23R planted on the left and right side plates of the housing 2. Further, a cut-and-raised piece 21 is formed at a predetermined position on the recording paper presser plate 16, one end of the coil spring 19 is locked to this cut-and-raised piece 21, and the other end is attached to a predetermined fixing point, for example, a pin 20. The recording paper pressing plate 16 is always biased clockwise in FIG. 2 by being locked.

The operation of the recording apparatus having the above configuration will be explained below.

First, in order to record on the recording paper 4, the sprocket guide arms 11L, 11R are lifted upward, and the sprocket guide arms 11L, 11
Since the wire springs 24L and 24R move the sub-arms 22L and 22R to the positions indicated by the two-dot chain lines in FIG. It rotates clockwise due to the biasing force and moves upward to the position shown by the two-dot chain line. Therefore, the tip of the recording paper presser plate 16 and the feed roller 10 are separated from each other.

Next, the feed roller section 18 is rotated counterclockwise around the shaft 8 as shown by the two-dot chain line in FIG. , 9R1 into the sprocket hole 5 of the recording paper 4, and set the feed roller section 18 at a predetermined position. In this set state, the recording paper presser plate 16 is in an upward movement state, so it is not possible to shift the recording paper 4 or press the teeth 9L1 and 9 of the sprocket.
It is possible to set R1 without removing it from the sprocket hole 5. After setting, if the sprocket guide arms 11L and 11R are lowered in the counterclockwise direction as shown in FIG. By lowering the recording paper 4 to the solid line position, the recording paper 4 is brought into close contact with the feed roller 10, stabilizing paper feeding, and the distance between the surface of the recording paper 4 and the printer head 14 can be kept constant.

In the above embodiment, the sprocket guide arm 1
Although the case where the recording paper presser plate 16 is interlocked with 1L and 11R has been described, the recording paper presser plate 16 may be made to be able to move independently as shown in FIGS. 3 and 4. To explain FIG. 3, a boss portion 34 is formed at one end of the sub-arm 33, and a rotation shaft 35 is inserted into a through hole bored in the boss portion 34 and fixed with a set screw or the like. A motor is attached to the other end or it is linked to a predetermined movable part. A recording paper pressing plate 16 is fixed to the boss portion 34, a pin 32 is installed at the other end of the sub-arm 33, and one end of a wire spring 30 is locked to this pin 32. The other end of the wire spring 30 is locked to a pin 31 set at a fixed point. In this configuration, if the rotating shaft 35 is rotated so as to separate the recording paper presser plate 16 from the feed roller 10 before rotating the feed roller section 18, it will move upward as shown by the two-dot chain line. .

In the case of FIG. 4, the control is completely electrical, and the recording paper presser plate 16 is rotatably attached to a pin 44 set at a fixed point. Further, one end of a solenoid 43 is fixed to a cut-out piece 42 formed on the recording paper pressing plate 16, which is biased counterclockwise by a spring 41. When recording on the recording paper 4, for example, the solenoid 4 is activated in synchronization with the "on" state of the power supply.
