Abstract

PURPOSE:To provide a printer which enables free setting of the number of printing characters per unit line length on the receiving side by arranging a changeover circuit for selecting and outputting several kinds of signals and a font control section for setting the number of printing characters per unit line length receiving the output thereof. CONSTITUTION:A changeover circuit 1 is composed of a changeover switch 2 having a plurality of terminals A-C and a resistance R connected between each of the terminals A-C and a power source P and the terminals A-C are connected to a CPU3 as font control section, to which an ROM4 and an RAM5 are connected. When signals transmitted from the changeover circuit 1 are selected by setting a dial 9 to 1-8, a corresponding signal is inputted into the CPU3 to set the number of print characters per 1 inch.

Description

[Detailed description of the invention] [Technical field of invention] The present invention relates to a receive printer.

[Technical background of the invention and its problems]

With conventional receive printers, the number of characters printed per inch in terms of line length can be changed to, for example, 10 characters, 12 characters, or 16 characters, but this can be changed depending on the type of command received from the sender. It is something.

Therefore, on the receiving side, there is a problem in that it is not known which font will be used for printing until the printing operation begins.

[Purpose of the invention]

The present invention has been made in view of the above points, and an object of the present invention is to provide a receiver printing system in which the number of printed characters per unit line length p can be freely set on the receiving side.

[Summary of the invention]

The present invention provides a receive printer having a plurality of fonts, which is provided with a switching circuit and a font control section, the switching circuit inputs a desired signal to the font control section, and the font control section is controlled according to the type of the input signal. is configured such that the number of characters to be printed per unit print line length sb can be set.

[Embodiments of the invention]

An embodiment of this invention will be described based on the drawings.

(1) is a switching circuit. This switching circuit (1) includes a switching switch (2) having a plurality of terminals (Al (Bl (c)).
), the terminal (At (Bl (C)) and the power supply (
P) and a resistor (R) connected between the two. In addition, terminals (A), (B), and (C) are connected to the CPU (3), which is the font control unit.
3) is connected to ROM (4) and RAM (5).

The changeover switch (2) has a dial (9) and a dial OQ on its surface, and is divided into three switches (Ss) (Sg) (Ss) as shown in FIG.

The first switch (S is a contact (1) (2)...
(8rito movable contact (al and yoshinashi, second switch (
The third switch (Ss) is the contact point (1 point (2 steps)...
(20)...(8o) and the movable contact (o). These movable contacts (-1(4)(o)) are held by the dial (9), move in conjunction with each other like the hands of a clock, and are fixed at arbitrary positions.

The movable contact (al is connected to the terminal (At), the movable contact (machi is connected to the terminal (Bl), and the movable contact (-1 is connected to the terminal (C1). Also, the contact of the first switch (Sl) (
1 (2) (3a) (4 is connected to each other and grounded, the contact (1) of the second switch (Sg) C24) and the contact (54) (6 is connected to each other and grounded,
Contact of the third switch (Ss) (1') (30) (
5") (7) are connected to each other and grounded.

In this configuration, the signals transmitted from the switching circuit (1) can be selected by turning the dial (9) according to the scale of 1 to 8.

In other words, the voltage to which the resistor (Tayosimi pressure) is set is applied to the movable terminal (al (C1) with a weight of 1, but the movable terminal In other words, the voltage applied to the movable terminal (4) (41 (Gl) is grounded and drops.

Table 1 Table 2 Table 1 shows the connection positions of the contacts of each switch and the movable contacts for each position of the dial (9). Table 2 corresponds to Table 1, and assumes that the voltage applied to the terminal is <0> when the movable contact contacts a grounded contact, and the voltage applied to the terminal when the movable contact contacts an ungrounded contact. It is a table showing applied voltages with <1>. Therefore, eight types of signals can be obtained depending on the position of the dial (9). The signals selected in this way are input to the CPU (3), and the CPU (3) sets the number of characters to be printed in 1 inch ab.

〔Effect of the invention〕

Since the present invention is constructed as described above, it has the effect that the number of characters printed per unit line length can be freely changed on the receiving side by changing the signal emitted from the switching circuit.
