Description

[Detailed Description of the Invention] The present invention relates to a manually operated imprinter that can mechanically, quickly and clearly print required information in the entry fields of a form or slip.

In the past, necessary information such as customer name, code number, product name, amount, etc., was generally written by hand on forms or vouchers widely used for transactions.

However, in general, many types of ledgers incorporate contracts suitable for monthly installment sales, or have forms suitable for various transaction methods, and each of these photocopied ledgers, which make up a set of several sheets, Filling in the required information in the entry fields by hand is not only extremely troublesome, troublesome, and time-consuming;
When adapting this to the one-writing system, it is necessary to fill in the necessary information by hand with sufficient force, clarity, and care in order to ensure legibility.

In view of this situation, the present invention has been designed to make it possible to quickly and clearly fill in the entry fields of forms or slips by mechanical printing, without having to write by hand, thereby streamlining office work. Therefore, the gist of the present invention is that a rotary printing section is provided directly below a window provided on the imprinter base surface at a position corresponding to the entry field of a form or slip, and that the printing section is A carriage-type press section, in which a printing ribbon is attached to the upper surface side so that it can be freely fed out and the upper surface of the printing section is scanned, is mounted so as to be movable manually along a guide rail. A press roll is attached to the press roll, and a cam stopper that engages with the cam of the feed mechanism is attached to the rear of the press section, and a lever formed integrally with the cam is elastically supported so as to be rotatable around a fulcrum. A rod is connected to the lower end of this lever so that it can move back and forth in the front and rear directions, and a ratchet lever is attached to the front end of the rod with a claw for feeding the number ring of the rotary printing unit.The rod is moved back and forth using the pivot as a fulcrum. The lever is rotatably connected in the ratchet feeding direction as the ribbon winding reel is fed, and a lever that is integrally formed with the cam is provided with a ratchet engaging pawl for feeding the ribbon winding reel, which is supported by a spring. The imprinter has a configuration in which the ribbon can be wound without slack by ratchet feeding rotation of a winding reel.

Next, the present invention will be explained with reference to the embodiment shown in the drawings.
The base surface 1 of the imprinter A is designed so that the form B can be placed upside down so that the entry field to be printed faces the base surface 1.

A window 1' is provided at a predetermined position on this base surface 1, and this window 1
A rotary printing unit 2 is disposed directly below '.

A carriage type press section 3 is mounted so as to be manually movable along a guide rail 4 so that the upper surface side of the rotary printing section 2 can be scanned.

A printing ribbon 5 is attached to the upper surface side of the rotary printing unit 2 so as to be freely drawn out.

A press roll 3' is rotatably supported in the press part 3, and at a rear position of the press part 3, the feeding rotation operation of the rotary printing part 2 and the printing part are carried out as the press part 3 moves. A feeding mechanism section 6 is provided for feeding out the printing ribbon 5 attached to the printing ribbon 2.

That is, by manually moving the press section 3 along the guide rail 4, the form B set on the base surface 1 is moved to the press roll 3 against the upper surface side of the printing section 2.
A cam stopper 3a is attached to the rear of the press section 3, and is pressed by the press section 3 to print.

The feed mechanism section 6 is provided with a cam 6a that is pushed upward by engagement with the cam stopper 3a.
The lever 6b is integrally formed with the lever 6a.

As described above, the lever 6b is integral with the cam 6a, and is supported so as to be rotatable around the fulcrum 7.

As described above, when the cam 6a is pushed upward by the cam stopper 3a, the lever 6b is rotated in the direction of the arrow I in FIG. 2 against the force of the spring that elastically holds it.

Furthermore, a rod 6C is connected to the lower end of the lever 6b so as to be able to move back and forth in the front and back directions, and a number ring (including numbers, symbols, and combinations thereof) of the rotary printing unit 2 is attached to the front end of the rod 6C. The ratchet lever 8 with the attached ratchet lever 8 is rotatably connected around the pivot shaft 8' as a fulcrum, and as the lever 6b rotates in the direction of the arrow ■ as described above, the rod 6C moves forward. The ratchet lever 8 is rotated in the direction of arrow II in FIG. 2, so that the numbering feed pawl 9 is actuated to sequentially feed the prints on the print section 2.

Next, as shown in FIG. 2, the lever 6b is provided with a ratchet engaging pawl 11 for feeding the ribbon winding reel 10, which is resiliently supported via a spring, and as the lever 6b rotates, the engaging pawl 11 The feeding ratchet wheel of the reel 10 is rotated to wind up the printing ribbon 5.

A lever 6d is provided in the middle of the rod 6C using a long hole and a pin so as to be interlocked with the forward movement of the rod 6C. A ratchet engaging pawl for feeding is provided to be elastically supported, and the roller 12 is rotated in the feeding direction of the ribbon 5 by ratchet feeding by swinging of the lever 6d, so that the feeding operation of the ribbon 5 is performed at predetermined intervals.

At that time, the ribbon 5 sent by the roller 12 is
Reel 10 so that the amount of winding is greater than the amount of feed due to
The ribbon 5 is frictionally connected to the rotating shaft 10' so that the ribbon 5 can be wound around the knoll 10 without slack.

Furthermore, after being unwound and wound up, the tension of the ribbon 5 allows it to slip.

Note that 13 is a reel on which the ribbon 5 is wound.

Note that 14 is a guide for positioning the form of the dumpling set, and 15 is a stopper for regulating the slide range of the press section 3.
This allows the fixing position to be freely selected by means of a pushbutton provided at the rear (not shown).

When using the imprinter of the present invention, the press section 3 must be
is placed in a standby position on the left side of the guide rail 4 in the figure, and the copying form B that requires printing is turned over and set in a predetermined position on the base surface 1. From then on, press section 3
By simply manually moving the switch to the right side in the figure along the guide rail 4, the press roll 3' of the press section 3 can press the upper surface side of the printing section 2 and scan the printing section at that time. The symbol, number, or a combination thereof displayed by 2 can be printed in a predetermined entry field of form B, which is a photocopy type.

Printing is performed on the bottom surface (actually, the front side) of the form B turned over in this way via the ribbon 5.

After taking out the form B printed in this way from the setting position on the base surface 1, if the press part 3 is returned to the predetermined position on the left side in the figure along the guide rail 4, the press roll Since there is a gap between 3' and the printing part 2 so that they do not come into contact with each other, the press part 3 can smoothly return to the left position, and at the same time, the cam stopper 3a of the press part 3 By engaging and following the cam 6a of the feed mechanism section 6, the lever 6b and the rod 6
By the valve operation of C1 and the ratchet lever 8, the printing in the printing section 2 is sequentially fed and the ribbon 5 is fed out to a new ribbon surface automatically.

In this way, by sequentially repeating the next printing operation, all printing of rank prints can be performed automatically, accurately, and mechanically.

In the above embodiment, the case where the printing section 2 is placed in one place is explained, but the printing section 2 may be installed in a plurality of places corresponding to the press section 3, and in addition to the printing section 3, for example, A lithographic printing section for printing fixed items such as the above may also be installed. In this case, since the printing stroke becomes long, it is necessary to remove the stopper 15 or relocate it to an appropriate location.

In the above embodiment, the feed mechanism section 6 is operated by making one reciprocation of the press section 3, but this is in conjunction with the operation of sliding the press section 3 to the right side. It is also possible to operate the feed mechanism section 6 at the same time.
