Abstract

PURPOSE:To enable to print on a multi-sheet slip or the like with a simple operation, by assigning the number of repeated operations for the same numerical value. CONSTITUTION:When each of keys on a keyboard KB is depressed, a corresponding key signal is fed to a calculating circuit part L, and a printer SPR is driven by a predetermined calculation output. Numerical value information and the number of repeated numbering operations are stored in an RAM provided in the circuit part L. Accordingly, the same numerical value can be repeatedly printed in a numbering printing process, and printing on the multi-sheet slip or the like can be easily conducted by assigning the number of repeated operations.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention prints consecutive numerical values on recording paper in sequence.
That is, the present invention relates to an electronic device with a printing device that performs numbering.

Conventionally, it has been necessary to print serial numbers, that is, consecutive numerical values, in tasks such as tabulation work, product code creation, and document sorting.

Conventionally, the method used for this purpose is that the user manually selects the numerical value placed on the type wheel, sets the initial value, applies an ink tube with the stamp pad, and presses the stamp against the paper surface. When the required number is printed on the paper, the type wheel is automatically rotated by one mechanically. Similarly,
Print the next value. From then on, this was repeated to complete the numbering process. This method not only bothers the user's hands but also takes time. In addition, the number to be printed is counted up by 1 on the printing back, so for example, when numbering a 3-page slip, 3 sheets 1 It is not possible to process a set of slips at once, and after performing numbering once and printing the last number, initial settings must be performed again and the second and sixth printing must be performed. Such operations are troublesome and troublesome.The present invention was developed in view of the shortcomings of printing, and by specifying the number of repetitions of the same numerical value, it is possible to print the aforementioned multi-page slips, etc. with a simple operation. An embodiment of the present invention will be described below with reference to the drawings.0 Figure 1 shows an embodiment of the present invention, which is an electronic numbering device that also functions as an electronic desktop calculator. This is a perspective view of the mode selector switch MSS, which also serves as a power switch and selects between the computer mode and the numbering mode, which currently indicates the numbering mode. PC is the printed wiring board inside the main body, KD is the printing section, IR is the ink roller, G
R indicates a non-slip grip during printing operations, W indicates a window made of transparent resin etc. for positioning the printing location, and the sheet paper printed by 5pFi numbering. After data is set from the keyboard part KBK, the numbering is done on the sheet paper SP. After placing the main body of the device and confirming the printing position through the window W, press the exit key and press 'FL' to print the numbering.

FIG. 2 is a schematic block diagram of the numbering device of FIG. 1.

In FIG. 2, 'B' is a keyboard section, and when each key is pressed, a corresponding key signal is sent to the arithmetic circuit section. The arithmetic circuit section is usually composed of a one-chip LSi, and the inside is composed of the following functional parts. ROMFi is a read-only memory that stores microinstruction information for performing sequential control, such as processing information necessary for d calculation, such as information on positioning numbers and four arithmetic operations, and numbering control when printing on sheet paper. This is an arithmetic unit that performs arithmetic processing according to the information from the OUFiROM that stores information, etc. It includes an adder for performing the arithmetic operations, and a key hoarding unit that outputs a KBK key scanning signal and uses λ to identify the key. It also includes a control section that controls the RAM section and 20 printer control sections. The RAM is a random access memory that stores numerical data etc. input from the keyboard section KB. Part 20 is a printing control part for driving the printing device SPR according to commands from the calculation part U. It stores the signal for driving the hammer solenoid SH, and stores the buffer register BR and the data to be printed in 4 bits. Moheterconte controls the print register PR for storing character codes, the timing counter TO corresponding to the characters on the type wheel, and the pulse motor! −
A matching circuit GO-? is used to match the data code stored in the error MG or printing register PR with the timing counter TO. --It consists of a Philips 70 tube SF% that detects whether it is in roll paper mode or sheet paper mode.

The SPR is a print control unit and is composed of the following parts. KL) is a hollow type wheel, and a type belt made of an elastic member is attached to the outside of this hollow type ring, and type belts are provided with type at a predetermined pitch in the circumferential direction. . Inside the type ring KD, a plurality of hammer solenoids SH are provided corresponding to the type belt, and each solenoid is equipped with a hammer.

SR and SW are O when the device is placed in a horizontal position.
This is a switch configured to be N.

This is a detector that outputs the home position of the type wheel to the print control circuit. This signal resets the timing counter TO to the initial value. ODl is a drive circuit for driving the hammer solenoid, and D2 is a drive circuit for driving the hammer solenoid. FIG. 6 shows an example of a key operation of an electronic device according to an embodiment of the present invention and an example of printing associated therewith. Figure 4 shows R in Figure 2.
This is a 74-chart of part of the microinstruction information that has been programmed into the OM. In the flowchart, NR and NextNO are registers in the RAM, the numbering register NR stores numerical information to be printed, the numbering number register NclK stores the number of repetitions of numbering, and the numbering number counter NG stores numbering information to be printed. This is a counter that is decremented each time it is printed, and when it is printed a predetermined number of times, the initial value stored in NC1 is set.

Next, the key operations and printing shown in FIG. 3 will be explained according to the flowchart. (2) When the key is pressed, numeric value data 2 is stored in NR. Next time you press the bad key, NG)
The contents of NR, ie, 2, are stored in NGI. Next (1)
When you press l1m[Q], the numerical value data 100 will be set to NR.
is stored in When the old key is pressed, the numerical data 100 in NR is transferred to the print register PR, and the print routine prints 100 on the recording paper.

To explain the printing routine in more detail, the clock pulse CPKr motor control MO and timing counter TO are operated to drive the pulse motor via the motor driver D2.

Character star B with a type wheel that rotates in conjunction with a pulse motor
The hammer driver D1 is used to energize the hammer and the renoid, and the hammer located inside the hollow type ring strikes the type ring from inside to print @0''.

Similarly, "b"1" is printed, and the first printing of "100" is completed.

Next, since N0 = 2 now, N (subtract 1 from 3 and
=i. Next, when the old key is pressed, the second "100" is printed on the recording paper in the same way as the previous printing, and since N0=1 at this time, only one N)1 is counted and amplified. 101” N G K NCI contents 2
Store.

Next, when the old key is pressed, since the current content of NR is "101", "@101" is printed, and by pressing the old key, "101"''102"@102" is printed.

As described above, according to the present invention, it is possible to repeatedly print the same numerical value for numbering, and it is possible to easily print multiple sheets of slips by simply specifying the number of repetitions using a key. Choose something that makes the application applicable.

Although an electronic desktop calculator capable of printing on sheet paper has been described as an electronic device, the present invention is not limited to this, and can be applied to a numbering-only machine, for example, and various other applications can be made without departing from the gist of the present invention. .
