Description

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

In general, it is necessary to print serial numbers and consecutive numerical values in tasks such as tabulation, product code creation, and document organization.

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 ink with a stamp pad, and presses the stamp onto the paper. As a result, when the required numerical value is printed on the paper, the type wheel rotates by one rotation. Print the next value in the same way.

This process was then repeated to complete the numbering process.

This method not only is cumbersome for the user, but also takes time.

The present invention has been made in view of the above-mentioned drawbacks, and relates to an electronic device that automatically performs numbering without bothering the user.

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows an embodiment of the present invention, which shows a perspective view of an electronic numbering device that also serves as a horizontal function of an electronic desktop calculator (calculator), and a mode that also serves as a power switch to select between a calculator mode and a numbering mode. Selector switch M88 now indicates the numbering mode. Also, KBq data input keyboard part, DP is display part, printed wiring board inside PCFi main body, KD is printing part, 1RFi ink claw 2, aaFi non-slip grip during printing operation, WF
i Window made of transparent resin etc. for positioning the printing place, SP indicates the sheet paper on which numbering is printed. After setting the data using the keyboard part KB, place the numbering device main body on the sheet paper 8P, and use the window W to set the printing position. After checking, press the l key to print the numbering.

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

In FIG. 2, KB is a keyboard section, and when each key is pressed, a corresponding key signal is sent to an arithmetic circuit section 1. Send to. The arithmetic circuit section LF1 is usually composed of one chip Lsi, and the inside thereof is composed of the following functional parts. R
OM is a read-only memory that stores microinstruction information for sequential control.
For example, processing information necessary for calculations, ie, information on numerical values and four arithmetic operations, processing information for controlling numbering when printing on sheet paper, etc. are stored. U is an arithmetic unit that performs arithmetic processing according to information from the ROM, and outputs a key scanning signal to the adder for performing arithmetic operations and the keyboard unit KB, and by inputting it, it distinguishes the key. It is composed of a control section that controls a RAM section and 20 printer control sections. RAMti is a random access memory that stores numerical data input from the keyboard gKB. The 20th part is a printing control part for driving the printing device SPR according to the command from the calculation part U, stores the signal for driving the hammer solenoid 8H, and stores the buffer register BR and the data to be printed in 4 bits. The data code and timing counter stored in the print register PR for storing character codes, the timing counter TC corresponding to the characters on the type wheel, the motor controller Me that controls the pulse motor, and the register PR for printing. It consists of a matching circuit CO for matching with TC, a filling frog 8F for detecting whether the mode is roll paper mode or sheet paper mode, and so on.

SPRq is a printing control device, which is composed of the following parts. KD is a hollow type ring, 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 letters at a predetermined pitch in the circumferential direction.

Inside the type ring KD, a plurality of hammer solenoids 8H are provided corresponding to the type belt, and each solenoid is provided with a hammer i-. sB-,
The axis switch is configured so that it turns ON when the swFi device is placed in the correct horizontal position.

M is a pulse motor, which is linked to the type wheel KD and rotates the type wheel. . HP is a home position detector that outputs the home position of the type wheel to the printing control circuit, and this signal is used to control the timing counter TC.
is reset to its initial value.

D1 is a drive circuit for driving the hammer solenoid, and D2 is a drive circuit for driving the pulse motor.

FIG. 3 shows a key operation diagram and a printing example for setting the initial value of numbering for an electronic device according to an embodiment of the present invention.

For example, a case is shown in which it is desired to number 4 digits with 1 as the initial value. By setting the initial value 1 by pressing the key 4 times, specify not only the initial value but also the number of digits to 4 digits, and by pressing the old key, the initial value reference #
Print 1 and press the key shown below to print 0002.
The count is sequentially increased from 0003 to 0004 and printing is performed.

Control for this purpose is programmed into the ROM shown in FIG.

When the group key is pressed, a key signal is sent from the keyboard to the calculation unit, and the calculation unit stores 10" data in the RAM and also writes @0" data to the print register PR as a 4-bit character code. Store as . Next, when the key is pressed again, the same process as described above is performed and data "0" is stored in the lower digit of the shift register P as a 4-bit character code. Next, by pressing Qo[], '''0''@1 is written in the print register PR in the same way.
``'' data is stored in PR, starting from the lowest digit ``''
A data code of 1"'"0"'0""0" is stored, and the high-order digit of the data code (7% 11) is stored.

Next, when the old key is pressed, a key signal is sent from the keyboard section to the calculation section U, and the following is executed according to the flowchart of FIG. First, the number of digits in PR is checked and 4-digit 1"4" data is stored as a 4 btt character code in the digit register KR in the RAM.

Then, by the print routine, the clock pulse CP
The timing counter TC corresponding to the characters on the type wheel rotates in conjunction with the pulse motor which operates the motor control MC and timing counter TC via the motor driver D2 and drives the pulse motor M via the motor driver D2.
The matching circuit CO checks the coincidence of the data of the lowest digit "1" of the print register PR, sends the data to the Bazza register, excites the hammer solenoid via the hammer driver D1, and presses the print wheel. is struck by the no/mar to print 11''. Similarly, "0"10""0
” and print it in order from the lower digits on the recording paper @0001'
" is printed. Next, add the numbering register NRK1 in RAM and transfer the contents of NR to PR. Now,
Here, the data for both NR and PR is "0002". Next, when the circle key is pressed, the same execution is performed and ``00Q2'' is printed on the completed paper. Similarly below, 0
003°0004 is printed. And 999
When it reaches 9, it returns to 0000, and printing continues thereafter.

In this way, the initial value and number of digits for numbering can be easily specified and printing can be performed sequentially by pressing the four keys, thereby improving the user's complicated work.

Although the #i electronic device has been described here as an electronic desktop calculator capable of printing on sheet paper, it is not limited to this, and may be used as a dedicated numbering machine, for example, and may be applied without departing from the gist of the present invention. be.
