Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to recording, and more particularly to a recording device that performs recording using a type assembly of a predetermined format.

[Prior Art] A daisy wheel printer is known as this type of recording device. This printer uses a type wheel with type formed on each tip of a predetermined number of spokes arranged radially at a predetermined pitch or made of an i-type material.The type wheel is rotated to select characters, and the desired type is applied to the printing hammer. After stopping at the striking position F, the type is struck by a printing hammer to perform printing. The struck type hits the printing paper on the platen 1- through the ink ribbon, whereby ink is transferred to the printing paper and printing is performed.

Such daisy-wheel printers are widely used in electronic typewriters and the like because they can perform high-quality printing.

[Problems to be solved by Part 1!11] By the way, in conventional daisy-wheel printers, the number of characters and the pitch between characters on the type wheel used in each printer are fixed to one type. The size of the typeface is determined within a predetermined range by the pitch between the typefaces.

For example, commonly used type wheels often have 96 or 100 characters, and the size of the type is 2.
It is about 4tm x 4 arms. In addition, the standard printing pitch is about 10 characters per inch for printing paper (-H) (different from the pitch between characters in -H). There is no particular problem in forming small type that corresponds to a smaller pitch, and electronic typewriters use type wheels with 12 or 15 characters per inch.

However, in recent years, with the diversification of printer specifications, there has been a demand for larger-than-normal print sizes, such as printing on business cards and headings, and as mentioned above, the number of characters on the type wheel and the pitch between the characters are fixed. Conventional daisy-wheel printers, in which the size of type is set within a predetermined range, have a problem in that they cannot meet this requirement.

This is a problem not only associated with daisy-wheel printers but also with other recording devices that perform recording using type assemblies of a predetermined type.

[Means for Solving the Problems] 1- In order to solve the above-mentioned problems, according to the present invention, in a recording device that performs recording using a type set of a predetermined format, the number and size of the type characters are different. a recording mechanism section that can selectively mount a plurality of types of type assemblies; a storage means that stores a plurality of types of recording mechanism section control information corresponding to each of said assemblies; A configuration is adopted that includes a control means that selects and uses the control information according to the type to control the mechanism section to perform recording.

[Function] According to such a configuration, a plurality of types of type assemblies having different numbers and sizes of type can be selectively mounted 71 in the recording mechanism section. Then, the recording mechanism section is controlled by the control means using the recording mechanism section control information according to the type of the attached assembly,
Recording is done. The user of the device can arbitrarily select the size of the type by selecting the type assembly to be attached.

[Embodiments] Hereinafter, details of embodiments of the present invention will be described with reference to the attached drawings.

FIG. 1 shows the external appearance of an electronic typewriter according to an embodiment of the present invention.

Reference numeral 1 denotes a keyboard, and character keys, numeric keys, symbol keys, and various function keys arranged here are used to input printing characters and various functions.

Reference numeral 3 denotes a platen, which winds the printing paper 4 and serves as a printing stand, and is rotatably driven by a drive means (not shown) to feed the printing paper 4.

On the other hand, a carriage 2 is slidably mounted near the platen 3.
It is driven by a carriage motor (not shown) and travels along the platen 3 in directions A and B. The carriage 21 is equipped with a type wheel 5, a print hammer 6, a wheel motor (not shown) for rotating the type wheel, and an ink ribbon cassette containing an ink ribbon as printing means. As mentioned above, the type wheel 5 is made of a predetermined number of spokes arranged radially at a predetermined pitch or made of a p-type material, each having a type molded at the tip thereof.

During printing, the carriage 2 is sequentially moved in the direction of arrow A at a predetermined printing pitch, and the type wheel 5 is rotated in accordance with the human-powered printing data from the keyboard 1.
Character selection is performed. When the target type is stopped at the striking position of the printing hammer 6, the printing hammer 6 hits it, and the struck type is transferred to the printing paper 4 via the ink ribbon.
The ink is transferred to the ink and printed.

By the way, in this embodiment, the type wheel 5 used is a conventional standard type wheel 5A shown in FIG. 2 and is different from the type wheel 5 shown in FIG. 3.
It is assumed that the two types B are alternatively configured so that they can be attached to the output rotation shaft of the wheel motor by means of a carriage 2''.

The type wheel 5B has the same distance at from the wheel center 7 to the center of the type 9 as the type wheel 5A, but the pitch between adjacent types 9 is twice, and the number of type characters 9 (spoke 8 ) has been halved. The vertical and horizontal sizes of the type characters 9 on the type wheel 5B are approximately twice those of the type characters 9 on the type wheel 5A.

In order to inform the CPU of the control system, which will be described next, as to which type wheel 5A or 5B is mounted on the carriage 2, an instruction for the type of type wheel mounted is inputted into the keyboard 1 shown in FIG. Wheel instruction key Kl
, 2 is set to 0, and for example, pressing the wheel instruction key Kl inputs an instruction for the type wheel 5A, and pressing the wheel instruction key 2 inputs an instruction for the type wheel 5B.

Next, the configuration of the control system of the recording mechanism section in the apparatus of this embodiment will be explained.

FIG. 4 shows an outline of its configuration. Reference numeral 10 indicates a type wheel 5A (5
The solenoid that is the drive source for the printing hammer 6 that strikes the type 9 in B), the wheel motor 11 mentioned earlier for rotationally driving the type wheel 5A (5B) to select characters, and the symbol 12 the carriage 2 It is a gear ridge motor that drives the.

Drive control of the drive sources of the solenoid 10, wheel motor 11, carriage motor 12, and other mechanisms (not shown) in the recording mechanism section are performed by a solenoid drive circuit 13, a wheel motor control circuit 14, a gear ridge motor control circuit 15, and the like, respectively. The processing is performed by a CPU (central processing unit 2ff) 16 that controls the entire apparatus via a dryer (not shown).

The CPU 16 has a well-known ROM (read-only memory)
A storage device 17 consisting of a RAM (Random Access Memory) and a RAM (Random Access Memory) is connected.

This storage device 17 includes a control program for the CPU 16 including a key manual processing routine corresponding to the human power of each key on the keyboard 1, as well as an arrangement of the print characters 9 on the print wheels 5A and 5B, and character selection control according to this arrangement. Control information for the recording mechanism section, such as a driving time table for the wheel motor 11, carriage feed pitch instruction information, and printing pressure information, is stored.

This control information is heat light depending on the difference between the type wheels 5A and 5B, and two types are prepared and stored in the storage device 17, one for the type wheel 5A and the other for the type wheel 5B.

With this configuration, the CPU 16 controls the solenoid 10, wheel motor 11, carriage motor 12, etc. of the recording mechanism section in accordance with the control program in the storage device 17 in response to input from the keyboard 1 to perform printing.

When operating the device of this embodiment, the operator first presses the type wheel designation key 1 or 2 to select the type wheel 5A or 5.
It is assumed that an instruction B is input.

Then, at the beginning of the key manual processing routine, the CPU 16 checks whether or not there is a key manual power of 1 on the wheel instruction key, as shown in step S1 of FIG. 5, which is a flowchart of the processing procedure. The type wheel 5A is selected as the control information for the recording mechanism used in the process, and the process proceeds to the following.

Also, if the wheel instruction key does not have the 1 sheep - manual power, then in step S3 it is checked whether the wheel instruction key has 2 key human power or not, and if so, in step S4 the control information of the type wheel 5B river is entered. Select and proceed to the following process. Also, error processing is performed when there is no 2 key manual input on the wheel instruction key or when there is no instruction for the print wheel.

The type wheel 5A mounted in this manner.

Control information for the recording mechanism section is selected according to the type of 5B,
Thereafter, the recording mechanism section corresponding to the attached type wheel is controlled, and printing is performed appropriately.

According to the apparatus of this embodiment as shown in J- below, in addition to the normal type wheel 5A, a type wheel 5B with approximately twice the size of the type is used, and in addition to printing of the normal size, it also prints twice the size of the type. Printing of various sizes can be performed, allowing for diversification of printing.

In the above explanation, the type of type wheel installed was input using the wheel instruction keys Kl and 2.
The type wheels 5A, 5B may be provided with an index for distinguishing their type, and a sensor for reading this index may be provided on the carriage, and information on the type of the type wheel may be input to the CPU 16 from this sensor.

Further, the selection process of control information corresponding to the type wheels 5A, 5B may be performed by other methods such as an interrupt.

In addition, the types of type wheels used are not limited to the two types mentioned above, but in addition to these, for example, types with a larger number of characters and approximately three times the size of the normal type wheel 5A, and those with a smaller number of characters and the size of the characters are also available. It is also possible to use one with four times as much. The reason why the number of printed characters is set to 1/integer of the number of printing wheels 5A and the pitch between printed characters is set to 1/integer/1/integer is to simplify the control of the recording mechanism section. Of course, it is also possible to use a type whose number of characters is not an integer fraction of the number of type wheels 5A. In this case, control information for the recording mechanism section corresponding to each type wheel is prepared, and the following information is provided. Of course, it is stored in the device 17.

Furthermore, it should be noted that it goes without saying that such a technique can also be applied to other recording devices that perform recording using a type assembly other than a type wheel.

[Effect] As is clear from the above description, according to the present invention, in a recording device that performs recording using a type assembly of a predetermined format, a plurality of types of type assembly having different numbers and sizes of characters can be recorded. a recording mechanism section that can be selectively mounted; a storage means that stores a plurality of types of recording mechanism section control information corresponding to each of the type assemblies; and a storage means that stores the control information according to the type of the attached type assembly; Since the configuration includes a control means that is selectively used to control the mechanical section and perform recording, an excellent effect can be obtained in that printing of different sizes can be performed and printing can be diversified.
