This platen 100 with respect to the platen 100
A print head P is provided which is movable in the axial direction of the platen over substantially the entire effective width of the platen as shown by arrow _A1 and which is driven by a drive circuit. rollers 201 and 301 for feeding the paper by rotating the right end of the slip 10 inserted from the insertion port 7c in FIG. 1 from above and below;
and rollers 201' and 301' are provided.
The rollers 201 and 201' have the same shaft 200.
and the rollers 301 and 301'
and are provided on the same axis 300. Furthermore, rollers 202 and 302 and rollers 202' and 30 roll the rising portion of the slip 10 along a guide (to be described later) into contact with each other from the front and back to feed the paper.

FIG. 3 is a left side view of the main parts inside the printer main body 1. In FIG. 3, parts corresponding to those in FIGS. 1 and 2 are designated by the same reference numerals. The slip 10 inserted along the guide 70 from the aforementioned insertion port 7c first passes between the rollers 201 and 301 and comes into contact with the support plate 32 of the limiter 30 which is rotatably mounted around the support shaft 31. will be inserted until At this time, the cam lever 40 to which the roller 301 is attached is rotated clockwise around the support shaft 41, so that a distance between the roller 301 and the roller 201 is widened. This is a cam lever 5 which is rotatably attached to a support shaft 51 and has a pin 52 implanted therein.
0 is biased counterclockwise by a spring 53, and therefore the cam lever 40 is in contact with the pin 52.
This is because it is biased in the direction of rotating clockwise around the support shaft 41. Therefore, at this time, the upper end 54 of the cam lever 50 supports the aforementioned idler roller 400, which is attached to the cam lever 60 via the support piece 62, on the support shaft 6 of the cam lever 60.
1 in a clockwise direction. For this reason, the idler roller 400 also includes the aforementioned drive roller 30 on the pulley 102 that rotates together with the platen 100.
3, the rotational motion of the pulley 102 is not transmitted to the drive roller 303. When the slip selection key 21 of the keyboard 20 in FIG. 1 is pressed, the first solenoid 600 is energized and the plunger 601 is retracted. For this reason, the cam lever 50
is rotated clockwise by overcoming the tension of spring 53, and accordingly, cam lever 40 is rotated counterclockwise by the tension of spring 42, and roller 301 presses slip 10 against roller 201. At the same time, the cam lever 60 is moved to the support shaft 61 by the tension of the spring 63.
As a result, the idler roller 400 rolls into contact with the pulley 102 and the drive roller 303, and the rotational movement of the pulley 102 rotates counterclockwise around the drive roller 30.
3. Drive roller 303 and roller 30

13 and a timing belt 320, so both rotate synchronously. As a result, the slip 10 is rotated between the rotating roller 301 and the roller 20.
1 and the drive roller 30.
3 and the rollers 202 and 202 rotate together. the first solenoid 6
The excitation/de-excitation timing of 00 is appropriately controlled by a control circuit, which will be described later, to obtain a predetermined paper feed for the slip 10. In this way, the slip 10 is given a predetermined paper feed and is moved to the platen 10.
When the print head touches the predetermined position of 0, the print head P
Printed by. Reference numeral 80 denotes a rear opening for loading full-width recording paper (in this example, 80-digit recording paper), a receipt 11 or a journal 12, and there is a discharge port 7a on the upper surface 8 at the upper part of the rear face 90 of the printer main body 1. It is provided in the lateral direction of the printer main body 1, substantially corresponding to the .

FIG. 4 is a right side view of the main parts inside the printer main body 1. As shown in FIG. In FIG. 4, parts corresponding to those in FIGS. 1 and 2 are designated by the same reference numerals. The journal 12 inserted from the back opening 80 along the guide 71 passes between the rolling contact roller 503 and the platen 100, and further along the guide 71, the journal 12 is inserted into the platen 1.
It is transferred toward the upper discharge port 7a while substantially touching the outer circumference of No. 00 by about a quarter of the circumference. This transfer is performed when the cam lever 513 is moved to the support shaft 523 by the spring 533.
This is achieved by being biased clockwise relative to the cam lever 513, thereby causing the rolling contact roller 503 attached to the cam lever 513 to press the journal 12 against the platen 100. Third solenoid 800
When is excited, the plunger 801 is attracted, and the cam lever 513 rotates counterclockwise.
Since the pressure contact with 00 is released, the transfer of the journal 12 is stopped. The timing of energizing and de-energizing the third solenoid 800 is appropriately controlled by a control circuit, which will be described later, so that a predetermined paper feed can be obtained with respect to the journal 12. In this way, the journal 12 is given a predetermined paper feed and is moved to the platen 10.
When the print head touches the predetermined position of 0, the print head P
Printed by. In addition, the cam lever 513
is engaged with a release lever 563 (provided approximately vertically) via an L-shaped cam 550 in which a pin 552 is embedded. As can be seen from FIG. 4, when the release lever 563 is pushed down by pressing the manual release button R3 attached to its upper end, the L-shaped cam 550 rotates clockwise about its support shaft 551. It engages with the cam lever 513. Therefore, the cam lever 513 is
As a result, the journal 12 is released from being pressed against the platen 100 by the rotary contact roller 503, and the transfer of the journal 12 is stopped.

The transport mechanism, printing mechanism, and their operations regarding the journal have been described in detail above, but receipt 1
The transport mechanism and operation of No. 1 are also exactly the same.

Next, when printing on full-width recording paper, the slip 10, receipt 11, and journal 12 are removed from the printer body 1, and full-width recording paper is inserted from the rear opening 80 of the printer body 1 in their place. Full width recording paper selection key 2 on keyboard 2
4, the first rolling contact roller 501, the second rolling contact roller 502, and the third rolling contact roller 503 explained with reference to FIG. The paper is fed at a uniform speed throughout. Of course, printing is performed on the slip 10, the receipt 11, the journal 12, and the full-width recording paper by a common printing head P.

The drive circuit and the control circuit for the print head P can be constructed, for example, as shown in the block diagram of FIG. In Figure 5, CPU
is a microprocessor, which includes a reset signal indicating that the print head P is at the reference position (left end position), a timing signal indicating the amount of displacement of the print head P from the reference position, and a keyboard 2 as shown in the figure. A slip signal based on the pressing operation of the slip selection key 21, a receipt signal based on the pressing operation of the receipt selection key 22, a receipt signal based on the pressing operation of the journal selection key 22, a journal signal based on the pressing operation of the journal selection key 23, and a receipt signal based on the pressing operation of the journal selection key 22. A full-width recording signal based on the pressing operation of the width recording paper selection key 24 is respectively input. In addition, the microprocessor
The following circuits are connected to the output side of the CPU. That is, an amplifier A _h for driving the pulse motor PM which controls the position of the print head P;
An amplifier A _p for exciting a solenoid SL that selectively drives the printing pins of the printing head P, the above-mentioned first
an amplifier A ₆ for energizing the solenoid 600 of
an amplifier for exciting a second solenoid 700 provided regarding the second pressure roller 502;

An amplifier A ₉ and the like for exciting a fourth solenoid 900 for driving a mechanism (not shown) is 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 above with respect to the embodiments, according to the present invention, desired printing can be performed on any of slips, receipts, journals, and full-width recording paper using a single printer, and each paper feed operation All of this is performed by rotational motion transmitted from the platen, and the timing of press contact and release of pressure contact with the platen is controlled by a control circuit (CPU), so the configuration is extremely simple. It is possible and the price is low. Also,
Full-width recording paper (80 digits in this example) can be used, so for example, if you print on the narrow recording paper used in a regular small printer to tally daily sales, the length will be several meters. Large amounts of data, which are difficult to handle, can be printed horizontally and shortened in length, so printing can be completed in a short time, and it can also be printed in a predetermined tabulation format. . This is extremely effective when creating daily or monthly reports.
