JPS62273857A - Dot serial printer - Google Patents

Abstract

PURPOSE:To easily print inclined letters like italic letters by a method in which printing is made by inclining the print head of a dot serial printer toward the direction of printing. CONSTITUTION:In the case of usual letter printing, a print head 1 is attracted by a fixing spring 5 and fixed to the shaft 4 of a solenoid 3 in the contracted state. In the case of italic letters, when the head 1 is attracted by the spring 5 and fixed to the shaft 4 of the solenoid 3 in the extended state, the head 1 is turned toward the extended C' direction to become inclined. When printing usual letters, the vertical line 8 is matched with the row of head pins for printing, whereas when printing italic letters, the head pin row is inclined by an inclined amount 9 to the vertical line 8 and printing is made.

Description

[Detailed description of the invention] λ　Detailed description of the invention [Industrial application field] The present invention relates to a dot serial printer.

[Conventional technology]

Conventionally, when printing italic characters of the alphabet using this type of printer, the character pattern of normal characters was converted into a program within the printer, and a separate character pattern exclusively for italic characters was printed. Was.

[Problem that the invention seeks to solve]

When the above-mentioned conventional printer prints italic characters, the printing speed is slow because the printing is performed through a character pattern conversion program, which takes time.

Another drawback is that having a character pattern of italic characters requires a large amount of memory.

[Means for solving problems]

The printer of the present invention has a mechanism that allows printing by tilting the print head with respect to the printing direction.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a perspective view of a print head section according to an embodiment of the present invention. 1 is a print head, 2 is a base that supports the print head, 3 is a solenoid for rotating the head, 4 is a shaft of the solenoid, 5 is a spring for fixing the head position,
printhead 1 is printhead 1 for pace 2
It can freely rotate in the C or C' direction about the center of the axis.

FIG. 2 is a plan view taken in the direction from D to D' in FIG. Figure 2 (a) shows the print head 1 for normal character printing.
is attracted and fixed to the shaft 4 of the solenoid 3 in the contracted state by a fixing spring 5. Figure 2 (
b) is for printing italic characters and print head 1
is attracted and fixed by the fixing spring 5 to the shaft 4 of the solenoid 3 which is in an extended state, so that the print head rotates in the C' direction by the amount of extension of the solenoid shaft compared to when printing normal characters. This will put you in a state of leaning.

FIG. 3 is a perspective view of the print head pin tip 6 in direction A' from the person in FIG. 1, and the state in FIG. 2(a) is changed to FIG. It corresponds to b).

7 is the printing direction, 8 is a line perpendicular to the printing direction, and 9 is the amount of inclination. When printing normal characters, print by aligning the vertical line 8 with the row of pins, and when printing italic characters: Since the head is tilted, the head pin array is tilted by a tilt amount 9 with respect to the vertical direction line 8, and printing is performed.

Figure 4(a) shows the print result of the character "Hl" printed with the print head in the state of Figure 2(a), which has a normal character shape.
Figure 4(b) shows the print result of the character IH1 printed with the print head in the state of Figure 2(b), and the character is tilted by an amount of 9 with respect to the vertical line 8, and is printed as a shitalic character. It becomes possible.

〔Effect of the invention〕

As explained above, the present invention has the effect of easily printing slanted characters such as italic characters by tilting the print head of the dot serial printer with respect to the printing direction.
