Abstract

PURPOSE:To prevent the erasing of contents to be printed in a random access memory so far as the contents are printed on recording paper by detecting the completion of printing on recording paper of the whole contents to be printed in a store region. CONSTITUTION:Contents to be printed in a random access memory 10 are stored in store regions R1, R2, R3 separately corresponding to mobile stations 2, 3, 4. The contents stored in the store regions R1, R2, R3 are transmitted over a printer 5 through a line 11, and printed on recording paper 12 in succession. When recording paper 12 is used up completely, a detecting circuit 13 transmits a paper use-up detecting signal over a processing circuit 7 through a line 14. A console panel 15 is connected to the processing circuit 7. The console panel 15 includes a switch 16 for executing a printing command, a switch 17 for stopping printing and a key 18, etc. such as a ten key for selecting the mobile stations 2, 3, 4. The operation of the processing circuit 7 is displayed by a display means 19.

Description

TECHNICAL FIELD The present invention relates to a method for printing by a printer content to be printed that is stored in a random access memory.

BACKGROUND ART The memory capacity of the random access memory can be reduced by printing the content to be printed stored in the storage area of the random access memory using a printer and then erasing the content to be printed.

In typical prior art, when a printer is printing, the stored contents are sequentially erased as each character is printed.

Problems to be Solved by the Invention In such prior art, the printer continues to print even after the recording paper is consumed during the printing operation, and as a result, it is difficult to print on one recording paper. Even though this was not done, the content that should have been printed ended up being erased.

SUMMARY OF THE INVENTION An object of the present invention is to provide a printing method for a printer that is improved so that the content to be printed in a random access memory is not erased unless printing is performed on a recording sheet.

Means for Solving Problem 5V The present invention stores content to be printed in a storage area of a random access memory, prints the content to be printed by a printer, and prints all content to be printed in the storage area. This printing method for a printer is characterized in that it detects that printing on a recording paper is completed and then stores the content to be printed stored in the storage area.

Function According to the present invention, the content to be printed stored in the storage area is erased only when all the content to be printed on the recording paper has been printed. If the recording paper is erased and used up during the process, the printing operation can be stopped and the content to be printed can be printed again from the beginning on a new recording paper. In this way, write the paper
It becomes possible to reliably print all the contents of the random access memory that should be printed on the user.

Embodiment FIG. 1 is a block diagram of an embodiment of the present invention. The base station 1 provided at a fixed location and the mobile station 21314 mounted on a car or the like can selectively make wireless calls to each other. The number of calls per meter between the base station 1 and the mobile station 2.3.4 can be printed out by the printer 5.

A processing circuit 7 realized by a micro combinator or the like is connected to a transmitting/receiving circuit 6 that performs wireless communication with the mobile stations i3 and i4 in the base station 1.

This processing circuit 7 includes an input/output circuit 8 and a microprocessor 9.
and a random access memory 10. The contents to be printed in the random access memory 10 are stored in four areas R1 and R2 in stores individually corresponding to the mobile stations 2.3.4.
, R3.

The store contents of store areas R1, R2, and R3 are line 1.
1 to the printer 5, and are sequentially printed on the recording paper 12. When the recording paper 12 is used up, the detection circuit 13 provides a paper out detection signal to the processing circuit 7 via the line 14.

An operation fi15 is connected to the processing circuit 7. Operation panel 15
includes a switch 16 for issuing a print command, a switch 17 for stopping printing, and a key 18, such as a numeric keypad, for selecting the mobile station 2.3.4. The operation of the processing circuit 7 is displayed by one display means.

! The operation will be explained with reference to FIG. ff12. Step n1
At step n2, the power of the base station 1 is turned on, and at step n2, the switch 18 is operated to perform a wireless communication with the first mobile station 2.
, R2, and R3 are the first . 2nd and 3rd
Mobile stations 2.3.4 are individually supported. When a call is established with the first mobile station 2, a value [11] indicating the number of calls is stored in the storage area R1 corresponding to the mobile station 2, as shown in Table 1. At this time, the mobile stations 2 and 3 are not communicating with each other, and therefore the contents of the corresponding storage areas R2 and R3 are zero.

(Hereinafter referred to as "FJ") In step n3 of Table 1, when the key 18 is operated to make a call with the second mobile station 3, the value of the door area R2 corresponding to the mobile station 3 becomes NJ. step n 4
When a call is made again to the mobile station 2 of rjSl, the value of the store area R1 becomes "2". step n 5
When a call is initiated with the third mobile station 4, the stored content of the storage area R3 corresponding to that mobile station 4 becomes "1". The number of individual calls between the base station 1 and the mobile stations 2, 3, and 4 is counted and stored in the store head j or R1, R2, and R3, respectively. Immediately before operating the print command switch 16 in step n6, the stored contents of the storage areas R1, R2, and R3 are e + In.
+n, if no paper break is detected in the detection circuit 13 at step n7,
Moving to step port 8, it is determined whether the printing stop switch 17 has been operated.

Otherwise, printing is performed on the recording paper 12 in the Stella 7'n9. In step nlo, it is determined whether all the store contents of the store areas R1, R2, R3 have been printed on the recording paper 12, and if so, in step nll, the store contents of the store areas R, 1, R2,
The stored contents of R3 are reset to zero.

In step n8, when the printing stop switch 17 is operated during printing, the process moves to step n12 and printing is stopped. At this time, store areas R1, R2, R
, 3 are as shown in Table 1, and the stored contents are not deleted. Further, when the recording paper 12 is completely consumed by the detection circuit 13 and a paper out detection signal is obtained, printing is stopped at step n12. In this way, store areas R1, R
2. If the printing operation is stopped before all of the stored contents of R3 are printed, the storage areas R1, R2,
The stored contents of R3 are not deleted but are retained.

Therefore, by replenishing the recording paper 12 and operating the print command switch 16, the storage area R
, 1, R2, and R3 can all be printed.

Since the stored contents of the storage areas R1, R, 2, and R3 are erased after being printed on the recording paper 12, there is no need to unnecessarily increase the storage capacity of the storage areas R1, R, 2, and R3. , it is possible to downsize and the configuration is f.
15 becomes simple.

In other embodiments of the invention, the detection circuit 13 and therefore the line 14 may be omitted. In the embodiment described above, the print command switch 16 and the print stop switch 17 are provided separately, but in another embodiment of the present invention, a single switch is provided that serves both switches 16 and 17, and this It may be configured such that when a single switch is operated while not printing, the printing operation is started, and when operated during the printing operation, printing is stopped. It is possible to reduce the number of

The present invention is not only useful in connection with counting the number of calls, but can also be broadly implemented for storing and printing other information in random access memory.

Effects As described above, according to the present invention, the content is erased after all the content to be printed has been printed on the recording paper, so that unnecessary content to be printed is not inadvertently printed. This makes it possible to reliably prevent the situation from disappearing.
