(Prior art) Figure 4 shows the actual application proposed by the applicant
141482, a configuration diagram of a paper feeding device of a recorder that reliably feeds paper, A shows a side sectional view, and B shows a front sectional view.

In the figure, reference numeral 1 denotes a continuous sheet of paper in which holes are successively provided at regular intervals l in the direction in which the sheet is fed, and perforations are made at regular intervals S, and the sheet is folded at these intervals S to be stored. Note that when bent in this way, the thickness is initially H'. 2 is a paper stock of height H having two chambers, one of which is
In chamber a, unused continuous sheets are stored (hereinafter referred to as "cassette"), and in the other chamber 2b, recorded continuous sheets are stored (hereinafter referred to as "receiving cassette").
3 is a housing in which the paper stock 2 is housed, and 3a is a spacer provided along the bottom surface of the housing 3, and has a thickness of t. A side spacer 3c is provided along the side surface of the housing 3, and has a U-shaped cross section so as to surround the cassette 2 together with the spacer 3a.

Reference numeral 4 denotes a feeding roller that feeds out the continuous paper 1 from the cassette 2a, 5 a sliding roller that feeds the recorded continuous paper 1 to the receiving cassette 2b, and 6 a presser roller that feeds the continuous paper 1 by friction together with the sliding roller 5. Note that these rollers 4, 5, and 6 are pivotally supported by side spacers 3c and supported on the paper stock 2.

7 is the continuous paper 1 sent from the feed roller 4
A flat part for recording is provided at the tip of the runway near the sliding roller 5.
8 is a receiving cover that guides the recorded continuous paper 1 to the sliding roller 5; 9 is a ceiling plate fixed to the housing 3 with a slight gap from the runway 7;
The gap between the runway 7 and the runway 7 should not be larger than a predetermined value. Reference numeral 10 denotes a light detection sensor located in a through hole provided in a part of the runway 7, which emits an electric signal every time the continuous paper 1 passes through the hole.

11 is a pen for recording on the flat part of runway 7;
12 is a pen cartridge for moving the pen 11 in the axial direction of the sliding roller 5.

Reference numeral 13 denotes a guide plate rotatably provided at a portion of the paper stock 2 near the feed-out roller 4, and is long enough to come into contact with the feed-out roller 4. 14 is a block fixed to the paper stock 2 in line with the guide plate 13; 15 is a leaf spring pivotally supported by the housing 3; The guide plate 13 is held in a position where it comes into contact with the feeding roller 4. A magnet 16 is fixed to the housing 3 and magnetically attracts the paper stock 2 made of a magnetic material.
is held in place in the housing 3.

In the paper feeding device having such a configuration, the continuous paper 1 is stored in the cassette 2a, and the paper stock 2 is fixed to the housing 3 via the magnet 16. At this time, the leading end of the continuous paper 1 is set by the guide plate 13 so as to come into contact with the feed roller 4.

The present invention, which achieves this purpose, includes a cassette 2a that stores folded and unused paper, and a feed roller 4 that feeds the paper from the cassette.
A paper feeding device comprising a sliding roller 5 for discharging the paper fed from the feeding roller, and a receiving cassette 2b for storing the paper discharged from the sliding roller in a folded state, which has the following configuration. It is.

First, a double box structure is used in which the cassette is an inner box and the receiving cassette is an outer box, and when the paper is stored in the paper feeding device, the cassette is located at the back and the receiving cassette is located at the front.

A lever 17 that holds the bottom surface of this cassette substantially flush with the bottom surface of the receiving cassette, and a spacer 3a provided at a portion facing the bottom surface of the receiving cassette when the cassette and the receiving cassette are attached to the paper feeding device. , an engagement release means 15 is provided for disengaging the lever when the cassette and receiving cassette are mounted on the paper feeding device.

However, when the lever is released, the cassette sinks relative to the receiving cassette by an amount equivalent to the thickness of the spacer.

(Function) The cassette and receiving cassette have a double box structure, and are engaged with each other by a lever before being attached to the paper feeding device. When attached to the paper feeding device, the disengagement means acts on the lever, and when the engagement between the two is disengaged, the cassette sinks relative to the receiving cassette.
Here, since the paper feeding device is provided with a spacer having a thickness of t at the position of the receiving cassette, the amount of sinking of the cassette is equivalent to this thickness. As a result, the distance between the folded paper stored in the cassette and the feeding roller increases, so that the paper can be fed easily.

(Example) The present invention will be explained below using the drawings.

FIG. 1 is a sectional view showing an embodiment of the present invention;
FIG. 2 is an enlarged view of the main part of the apparatus shown in FIG. 1, where A is a cross-sectional view and B is a side view of A from the direction of arrow C.
Incidentally, in these figures, the same reference numerals are given to the parts having the same functions as those in FIG.

In the figure, 3a is the thickness t provided in the housing 3.
The spacer is located at a position corresponding to the receiving cassette 2b, and an oblique side 3b is formed on the side closer to the cassette 2a. This thickness t is determined so that the rigidity necessary to support the rollers 4, 5, and 6 with the side spacer 3c that is integral with the spacer 3a is obtained. The paper stock 2 is provided with a receiving cassette 2b and a side plate 2c made of a magnetically permeable material, and has a double box structure, and the cassette 2a, which is the inner box, moves in the direction of arrow D along the side plate 2c.

Reference numeral 17 denotes a lever that rotates around a shaft 17a, and is connected to the cassette 2a through a hole 2d formed in the side plate 2c.
It has a length that reaches the hole 2e formed in the side wall of. A spring member 18 has one end fixed to the block 14 and the other end fixed to the lever 17, and generates a torque that causes the lever 17 to rotate in the direction of arrow E about the shaft 17a.

FIG. 3 shows the state in which the paper stock 2 constructed as described above is mounted in the housing 3. As shown in FIG.

FIG. 3A shows the paper stock 2 being moved in the direction of arrow F. Since the cassette 2a is integrated with the receiving cassette 2b by the action of the lever 17, it can be inserted into the housing 3 even if the spacer 3a is present.

In FIG. 3B, the paper stock 2 is connected to the magnet 16.
It shows the state where it is sucked and fixed. Here, when the lever 17 comes into contact with the leaf spring 15 and pushes it up in the direction of arrow G, the receiving cassette 2b and the cassette 2a are separated, and the cassette 2a is lowered by a distance t. Then, the distance between the paper stored in the cassette 2a and the feed roller 4 increases by t from (HH') to (HH'+t).

Figure 3C shows that the recording on the paper is completed and the cassette 2a is
This figure shows a state in which the paper stock 2 is pulled out in the direction of arrow J when the paper stock 2 has all been moved from the paper to the receiving cassette 2b. The cassette 2a is moved upward by the oblique side 3b, and when it comes above the spacer 3a, the lever 17 is activated and the cassette 2a becomes integral with the receiving cassette 2b.

(Effect of the invention) As explained above, according to the invention, the distance from the feeding roller 4 increases by the height H of the cassette 2a and the thickness t of the spacer 3a. , 6, the area that satisfies equation (1) is expanded, allowing reliable and smooth paper feeding.
