The axial direction thereof is substantially parallel to the ejection port of the printer main body l. This platen 100 is provided to the right of its main shaft 101 and is rotationally driven by a knitting lever movement means (not shown) such as a pulse motor. Further, on the left Ald side of the platen 100, a motion transmitting boo 9102 having the same diameter as the platen is coaxially provided. Corresponding to the platen 100, there is provided a print head P which is movable over substantially the entire length of the platen 100 in the axial direction of the platen as shown by the arrow A1 and is driven by a drive circuit. It is being Rollers 201 and 8011 and rollers 01' and 801' are provided to feed the paper by rolling the right end of the first slip inserted from the above-mentioned insert -7C from above and below. The aforementioned rollers 205 and 201
' are provided on the same shaft 800, and rollers 801 and 801' are provided on the same shaft 800. Further, rollers 202 and 802 and rollers 20 and 80 roll the rising edge of the slip 10 along a guide to be described later to convey the paper by rolling it into contact with it from after 00.
I'm being looked down upon. The rollers 202 and 202' are provided on the same strip 2101, and the rollers 202 and 202' are provided on the same number M81G as the p-rollers 802 and 802'.

Furthermore, there is an idler roller 400 on the left end side of @aio.
The pulley 102 can be connected to the pulley 102 through the fx'aEmo-
La aoa Kakonosuke 810Bm is fixedly installed. The first rolling contact roller 6 that is in rolling contact with the platen 1001

8 is provided.

The second rolling contact roller 602 is provided so as to roll in approximately the center of the width direction of the receipt 11, and the eighth rolling contact roller 508 is provided so as to roll into contact with approximately the center of the width direction of the journal 1g. It is provided so as to make contact with the center part.

Figure 8 shows the left hammer 1th1 inside the main body of the printer.
Figure 1. In the 8th factor, the same reference numerals are given to the corresponding parts in FIG. 1 and the salt 2 factor. The above-mentioned insertion lower c is inserted along the guide 70, and the slip 10 first passes through the junction of the rollers 201 and 801 to the shaft 1i11 of the support shaft 81.
The support plate 8 of the single limiter 30 is rotatably attached to the
It is inserted until it touches 2. At this time, the roller 801 is installed and one camlet t<-4o6; support #+4
The distance between the roller 201 and the roller 201 is wide because it is rotated clockwise in the first rotation. This is stupid, pivot 5
The cam lever 50, which is rotatably attached to the pin 52b; This is because it is biased in the clockwise direction. Therefore, this mechanism is attached via the supporting piece 62 of the cam lever 5F) upper end 5 ribs ≦ cam lever I (-601) and the above-mentioned idler roller 4.
00 is caused to shift clockwise by the rotation of the support 4i1i+61 of the cam lever 60. For this reason, idler roller 4
00 is a boo that rotates at the same time as the platen 100! J102
The pulley 10 does not roll into contact with the drive roller 808 mentioned above.
The rotational motion of No. 2 is not transmitted to the drive roller 8081. When the slip selection key 21 of the keyboard 20 in FIG. 1 is pressed, the first solenoid 600 is magnetized and the plunger 601 is retracted. This t-kome cam lever 50
The cam lever 40 overcomes the tension of the spring 58 and is rotated clockwise, so the cam lever 40 rotates counterclockwise and presses the roller 801 or the slip 10 against the roller 201. At the same time, cam lever 6 (b))
As a result of the rotation of the support shaft 61 in the counterclockwise direction due to the 6° tension of the spring, the idler roller 400 is turned! The rotational movement of the boot 1io2 is transmitted to the drive roller 808 by rolling contact with the J 102 and the drive roller 808. Drive roller 808 and roller 801 are coupled by respective timing pulleys 811 and 818 and timing belt 820, so that both rotate synchronously. As a result, slip 10i,
The paper is transported while being sandwiched between the rotating rollers 801 and 201, and is also driven;

The timing of energization and de-energization of the first solenoid 600 is appropriately controlled by a control circuit, which will be described later, so that a predetermined paper feed can be obtained using the slip 10. The slip 10 is thus given a predetermined paper feed and is moved to the platen 10.
When it touches the predetermined position of 0, it is printed by the above-mentioned print head P. 8o is Kanayama recording paper (80 in this example)
There is a back opening for loading a receipt 11 or journal 12 (digit recording paper), a receipt 11 or a journal 12, and there is a rear opening at the top of the back 9o of the printer main body 1, approximately corresponding to the discharge lower a of the upper surface 8. It is set in the direction.

Figure @4 is a right side view of the main parts inside the printer main body l. In FIG. 4, parts corresponding to @1 cause and @2 cause are denoted by the same reference numerals. Guide 71 from back opening BO
The journal 12 inserted along the contact roller 508
and the platen 100, and further along the kite 71, it is transferred upward toward the discharge lower a while touching the outer periphery of the platen 1θ0 about 1/4 of the way. This movement is supported by the cam lever 5Hl or the spring 688.
This is done by rotating the journal 12 against the platen 100, which is attached to the cam lever 518 by rotating the journal 12 in the N- direction. When the eighth solenoid 800 is energized, the plunger 801 is attracted, and the cam lever 518 rotates counterclockwise, so that the journal 12 is no longer pressed against the platen 100 by the rolling contact roller 508, so that the journal 12 cannot be transferred. Stop. The timing of excitation and non-FJjJ magnetization of the eighth solenoid 800 is appropriately controlled by a control circuit (to be described later), and a predetermined paper feed is obtained with respect to the journal 12. When the platen 1000 is fed, the platen contacts a predetermined position and prints (printed by the print head P mentioned above.The cam lever 518 is connected to a bottle 552, which is inserted through the L-shaped beam 550). It is engaged with a release lever 568 (provided approximately vertically).
As shown in the figure, when this release lever 568 is pushed down by pressing the manual release button R84 attached to its upper end, the L-shaped cam b50 or its support shaft 551
, it rotates clockwise and engages with the cam lever 518. Therefore, the cam lever 518 rotates counterclockwise as its support shaft 628 rotates, and as a result, the rolling contact roller 5G
The transfer of the L journal 12 is stopped until the journal 12 is pressed against the platen 100 by B.

The four transport mechanisms, printing mechanisms and their operations related to the journal have been described in detail above, and the transport mechanism and operation of the receipt 11 are also completely the same.

Next, when printing on Kanayama recording paper, slip 10,
cash register) 11 and journal 12 into one printer body 1
Insert Kanayama recording paper from the rear opening 80 of the printer main body 1 in place of J'L and the like.

When the recording paper selection key 24 is pressed on the keyboard 20, the control circuit operates to select the first contact row L601, which will be explained with reference to FIG. The second rotary contact roller 502 and the eighth rotary contact roller 508 all operate synchronously to feed the paper at a uniform speed over the pile of recording paper.

It goes without saying that the slip lO, the receipt 111, the journal 12, and the Kanayama recording paper are printed by the common print head P.

The drive circuit and the control circuit regarding the print head P are 5
! For example, as shown in the block diagram of the fifth ward, it can be configured as follows. In FIG. 5, CPLI is a microprocessor, which includes a reset signal that indicates that the print head P is at the reference position (left end position) as shown in the figure, and a reset signal that indicates that the print head P is at the reference position (left end position). Indicating timing signal, slip selection key 2 on key fob 2
1, a receipt signal based on the suppression operation of the receipt selection key 22, a journal signal based on the suppression operation of the journal selection key 28, and a Kanayama recording signal based on the depression operation of the key 24. The following circuits are connected to the output side of the microprocessor CPLJ. That is, the circuits CoC control the print head P. An amplifier Ah for driving the pulse motor PM, an amplifier for exciting the solenoid SL that passes through and drives the printing bin of the print head P, and an amplifier for exciting the first solenoid 600 mentioned above. Regarding the second pressure roller 602.

An amplifier A7 for energizing the second solenoid 700 provided as shown in FIG. an amplifier Ak for energizing a solenoid 900 @4 for driving a mechanism (not shown) that automatically releases the paper holding operation of a paper holding roller (not shown) when recording paper is loaded. etc. or connected. Control of signal output to each connected circuit based on each input signal described above is all executed by the microprocessor CPU.

As described in the embodiments above, according to the present invention, a single printer can perform desired printing on any number of slips, receipts, journals, and Kanayama recording paper, and each paper feeding operation can be performed easily. All of this is done by rotational motion transmitted from the platen, and the control circuit (CPU) controls the timing of pressing and releasing the pressure on the platen.
), the configuration is extremely simple and the price is low. For example, if you print on the narrow recording paper used in a small water-flowing printer to tally the sales of -day, you can print on the narrow recording paper (deposited in this color). Large data that is several meters long and difficult to handle can be printed horizontally and shortened in length, so printing can be completed in a short time. It can be printed. This is extremely effective when creating 8 sheets or monthly reports.
