Abstract

PURPOSE:To eliminate the need to re-register character patterns peculiar to an individual user, by providing a storage device containing a memory circuit for registering the character patterns peculiar to the user and a backup power source for the memory circuit in a body, in a detachable manner. CONSTITUTION:A detachable-type storage device 2 is provided so that it can be fitted to and detached from a dot printer device 1. The storage device 2 is provided with a RAM8 and a battery 9. A CPU3 writes character pattern data outputted from an information processor 12 into the RAM8 of the storage device 2. The RAM8 is backed up in power source by the battery 9. Therefore, the character pattern data peculiar to a user which are registered in the RAM8 are maintained even when the storage device 2 is detached from the dot printer device 1 or a power source for the dot printer device 1 is cut off. Thus, there is no need for the user to re-register his own character patterns when the power source for the printer device is re-turned ON.

Description

DETAILED DESCRIPTION OF THE INVENTION (1) Field of Industrial Application The present invention relates to a dot printer device that prints characters, figures, etc. by combining dots.

(2) Conventional technology Conventionally, a general dot printer receives an output character code from an information processing device such as a computer, and uses the code to refer to a character pattern made up of dots registered in an internal ROM to print dots. Was. In addition, some printers allow character patterns to be registered from an external information processing device to the internal RAM of the dot printer. It was possible to print out characters by referring to character patterns.

(3) Problems to be Solved by the Invention In the conventional dot printer device described above, it was possible to temporarily register a user's unique character pattern, but the user's unique character pattern registered in the internal RAM is
The data will be lost when the printer device is turned off.
When the power of the printer device is turned on again, there is an inconvenience in that the user must re-register the user's unique character pattern.

In addition, if the registered content is changed by another user, the user must re-register their own character pattern, and if they use another printer even if it is the same model, the character pattern The drawback was that the pattern had to be reset to the printer.

(4) Means for Solving the Problems The present invention has been made in view of the above points, and eliminates the need for each user to re-register their own character patterns in the printer device they are about to use. In order to achieve this purpose, we have provided a memory device that integrates a memory circuit for registering a user's unique character pattern and a backup power source for the memory circuit, and that this memory device can be attached or removed. is configured to do so.

(5) Effect In this configuration, each individual owns only a storage device that integrates a memory circuit and a backup power source for the memory circuit, and attaches it to the printer device, thereby allowing each user to register their own character patterns. No need to fix it. This allows multiple users to treat one printer as if it were their own dedicated machine.

(6) Examples Hereinafter, the present invention will be explained based on the drawings.

The drawing is a block diagram showing an embodiment of a dot printer device according to the present invention.

In the drawing, the dot printer device 1 includes a CPU 3, a bus 4, a ROM 5, a RAM 6, a ROM 7.1/F buffer 10. A printer mechanical system fill is provided.

The ROM 5 stores a program for the CPU 3 that controls the printer device. RAM6 is CPU3
used as a work area. ROM7 stores standard character patterns such as kanji, hiragana, numbers, etc.
M8 stores a character pattern for user registration supplied from the information processing device 12 via the I/F buffer 10.

The character code printed out by the dot printer 1 is supplied from the information processing device 12, and the character code output by the information processing device 12 is sent to the bus 4 through the I/F buffer 10 of the dot printer 1. CPU3 is R
This character code is analyzed based on the program stored in OM5.

Based on this analysis result, the CPU 3 reads the corresponding character pattern data from the ROM 7 and sends it to the printer mechanical device 11 via the bus 4. The printer mechanical device 11 performs printing at a position corresponding to each dot of the sent character pattern. Print output is performed dot by dot using various methods such as wire impact, thermal, and inkjet.

In addition, the dot printer device 1 is provided with a removable storage device 2 that can be attached to and removed from the dot printer device 1 at will. This removable storage device 2 is provided with a RAM 8 and a battery 9.

When the removable storage device 2 is attached to the dot printer device 1, the RAM 8 is electrically connected to the bus 4.

This RAM 8 is used to register a user's unique character pattern supplied from the external information processing device 12. The battery 9 is a backup power source for the RAM 8. When the removable storage device 2 is attached to the dot printer device 1, the RAM 8 is connected to the bus 4, so that power to the RAM 8 is supplied via the bus 4. At this time, the backup power battery 9 can be charged.

Registration of character pattern data in the RAM 8 is performed by sending the character pattern data from the information processing device 12. . In this case, in order to distinguish it from a normal character code printing operation, the information processing device 12 sends a scavenge code indicating that the command is not a character code to be printed but a command to the dot printer l before sending out the actual character pattern data. and a command indicating that the next operation is to register character pattern data.

The CPU 3 analyzes the command sent by the information processing device 12 according to the program stored in the ROM 5,
Thereafter, the character pattern data sent from the information processing device 12 is written into the RAM 8 of the removable storage device 2.

The RAM 8 in which this writing has been completed is used for reading character pattern data by the CPtJ3 in the same manner as the RAM 7 in which standard character patterns such as kanji, hiragana, and numbers are stored.

The RAM 8 is backed up by a battery 9. Therefore, even if the removable storage device 2 is removed from the dot printer device 1 or the power to the dot printer device 1 is turned off, the user's unique character pattern data registered in the RAM 8 is retained. Therefore, even when the power of the printer device is turned on again, there is no need to register the user's unique character pattern again.

In addition, if each user owns a removable storage device 2, the registered contents will not be changed by other users, and if the user's removable storage device 2 is attached to the dot printer device 1, the user's unique Character patterns can be used. Furthermore, when using another printer of the same model, resetting the character pattern can be omitted by simply attaching the removable storage device 2 to the printer.

(7) Effects of the Invention As explained above, the present invention provides a storage device that integrally houses a memory circuit for registering a user's unique character pattern and a backup power source for the memory circuit.
Since this storage device is configured to be removable, it is possible to eliminate the need for re-registering each user's unique character pattern in the printer device to be used from now on.

In addition, by allowing each individual to own only a storage device that integrates a memory circuit and a backup power source for the memory circuit and attaching it to a printer, it is possible for multiple users to use one or more printers as their own dedicated printers. It is possible to handle it as follows.
