Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a type printer, which has a function that allows the user to replace a set of type plates, and in particular, a type type printer that allows the user to easily check the arrangement order after replacing the set of type plates. Regarding printers.

Conventionally, to check whether or not the set type boards are stored in the correct order in the type storage, the task of pulling out the set type board and comparing the arrangement number attached to it with the storage number of the type storage is carried out using the storage number. The disadvantage was that it was very time-consuming because it had to be repeated in order.

Also, even if there is an error in the arrangement order of the set type plates and the printing result is incorrect, it is not easy to tell which number and storage number of the set type plate in the type storage is incorrectly stored. It was hot.

SUMMARY OF THE INVENTION An object of the present invention is to provide a type printer in which it is possible to easily check whether the set of type plates stored in a type storage are arranged in the correct order.

A feature of the present invention is that a test printing control means is provided for printing characters at predetermined positions on each typeface board in the order in which the typefaces are arranged, and it is possible to check whether the order of arrangement of the typefaces is correct based on the printed content. It is characterized by the following.

That is, when the set type boards are stored in the type storage in the correct arrangement order, when the set type boards are searched in the order of arrangement and the type at the designated address is typed, a series of sentences will be printed. After that, the user replaces the set type plate, performs the same printing operation as above, compares the print result with the series of sentences above, and if the two match, the set type plate has been stored correctly. I know that there is. If there is an error, by checking the printing order at that location, the storage number of the erroneously stored set type board can be determined.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 5. Figure 1 shows the type printer mechanism.
A series of printing operations will be explained with reference to the flowchart shown in FIG. The set type plate 1 is comb-shaped, and type characters are formed on the comb teeth. The hammer 3 is always in a fixed position and hits the comb teeth from the back side of the type to print on the paper 12 via the ink ribbon 13. The type storage 2 stores a plurality of set type boards 1 radially. A storage number is determined for each storage position, and the array number of the typeface board 1 to be stored is also determined corresponding to this number. Therefore, each type is stored in the storage device of the controller as the storage number of the type storage 2 and horizontal and vertical position information with respect to the hammer 3.

In order to select and print on the set type board 1, the set type board 1, which has been lifted from the type storage 2 by the motor 6, is stored in the type storage 2. Next, the motor 4 controls the rotation (θ) of the type storage 2 to select the set type board 1, and the motor 5 controls the position (x) of the hammer 3 to horizontally search for type to be printed. Next, the motor 6 lifts (y) the set type board 1 to search in the vertical direction. Thereafter, the hammer 3 is energized to perform a printing operation, and the ink ribbon 13 and platen 9 are fed by one character pitch by the motor 7, completing the series of operations. The paper is fed by rotating the platen 9 with the motor 8. If the type to be printed next is on the same set type board 1, the set type board 1 is not stored in the type storage 2, and the horizontal position of the type storage 2 is controlled.
The printer performs vertical direction control and begins printing operation.

In this way, printing is performed by controlling the rotation and position of the type storage 2 based on the storage number and position information of the storage device corresponding to the type, so the arrangement number of the set type board 1 and the storage number of the type storage 2 match. Otherwise, correct printing results will not be obtained.

FIG. 2 is an example of a controller block diagram for controlling the mechanism section 27. A processing unit (CPU) 21 controls the mechanism section 27 according to the information contents from the storage devices 22, 23 and the test switch 24. Note 25,
26 is an interface. FIG. 3 shows a flowchart of a test program read out from the storage device 22 and executed by the CPU 21 when the test switch 24 is pressed in this controller.

When the test switch 24 is pressed, the characters specified by the program are printed in the order of the storage numbers of the character storage 2. The test program ends when printing on all the stored set type plates 1 is completed. An example of a correct printing result at this time is shown in FIG.

In this embodiment, the number of sheets stored in the type storage 2 is 36, and the set type board 1 has array numbers 1 to 36, and the numbered characters and/or the type for creating phrases corresponding to each array number are attached to the set type board 1. is provided. Example A is an example in which characters that are easier to check are selected and printed one by one from the type letters arranged on each set type plate 1, and example B is an example in which letters with serial numbers for checking are printed when the set type plate 1 is manufactured. I prepared it and had it printed.

Therefore, when the set type board 1 containing serial number test characters is stored in the type storage 2, the test switch 24 is pressed, and the test print is performed. It turns out that array numbers 4 and 5 of 1 were incorrectly stored.

As described above, according to the present invention, after the work of storing the type board 1 into the type storage 2, it is possible to check whether the type board 1 has been stored correctly and, if there is a mistake, to know where the mistake is. There is an effect that can be done.

According to the present invention, since it is possible to know the arrangement state of the set type plates in the type storage, it is possible to easily know if the set type boards are incorrectly stored in the type storage and the location thereof, and to replace the set type plate. This has the effect of reducing printing time and at the same time ensuring printing accuracy.
