Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to an image recording device, and more particularly to an image recording device configured to automatically determine a recording start position according to the size of recording paper. It is related to the device.

[Prior Art] For example, in order to use 34-size recording paper and A4-size recording paper in an image recording device using a thermal head, etc., the left edge must be cut as shown in FIG. Recording paper was set as a reference.

When such a recording paper setting method is adopted, the recording start position is always fixed at the same position, so many apparatuses employ this method.

However, this method of setting recording paper is not the only one; there is also a method of setting recording paper by aligning the centers of each of the 34-size and A4-size recording papers, as shown in Figure 1 (b). .

If such a setting method is adopted, the recording start position must be changed.

However, if the recording start position is made variable, a complicated control circuit must be installed, which results in a complicated control device, resulting in a significant increase in cost.

[Objective] The present invention has been made in order to eliminate the above-mentioned drawbacks of the conventional art, and it is an object of the present invention to provide an image recording device in which the recording start position can be freely changed using an extremely simple control circuit. It is an object.

[Example] Hereinafter, the present invention will be described in detail based on the example shown in the drawings.

FIG. 2 is a bookmark diagram explaining the basic configuration of the present invention. In the figure, what is indicated by the symbol l is an input means, and the signal inputted by this input means 1 is guided to the first stage 2 and recorded. The recording opening position is determined by controlling means 3. A storage means (memory) 4 is attached to the control means 2, in which processing programs 1i)'e are output and written.

Based on this circuit configuration, when the size of the recording paper changes, the operator inputs a key to determine in the storage means 4 whether or not the recording paper to be used from now on is the size 2 recording paper. A new recording start position can be automatically determined according to the stored recording start position j;Q'. The operation of the control means 2 is performed according to the flowchart shown in FIG.

In Figure 4, "rMODE setting" is used to determine the recording start position, and rMEMORY ADDRE
"SS Setting" sets the memory address pointer to the recording start position. FIG. 3 shows a specific configuration of the above-mentioned control means.

In Fig. 3, the reference numeral 11 indicates C, PU (central processing unit), and this CPU II has input port 12, ROM
A read only memory (read only memory) 13, a RAM (random access memory) 14, and an output capo I.15 are connected, and a printer 16 is driven and controlled via the output capo I.15.

In the circuit configuration as described above, image data input from the input port 12 is stored in the RAM 14. At this time, in the case of recording data of 34 size for the storage area for one line set in advance, storage starts from the start address of the RAM 14, and in the case of A4 size, the storage is started at a predetermined address, for example 20.
Storage starts from an address shifted by bytes.

When reading one line of data from the RAM 14, the printer 16 always reads it from the first address.

As a result, in the case of 34 size data, recording starts from the left edge of the recording paper, or in the case of A4 size data, recording starts from the left edge.
The byte-th becomes the recording start position.

However, in this embodiment, the recording head installed in the printer 16 is a 34-size thermal head, and has a 3-bit recording head.
/mm, that is, 2048 bits, corresponds to one line.

In this way, the recording start position can be automatically determined depending on the size of the recording paper used.

Note that although the two consecutive examples show the determination of the recording start position corresponding to the method of setting the centers of A4 size and 34 size together, the recording start position can be arbitrarily set in units of 1 byte.

In addition, in the above-mentioned embodiment, only the case of A4 size and 34 size recording paper was explained, but of course there are more than two types.
The present invention can also be applied to the case where many types of recording paper of different sizes are used.

This can be easily handled by simply changing the program.

In this way, it is possible to provide an image recording apparatus which can arbitrarily move to a recording start position at an extremely low cost with an extremely simple structure consisting of a CPU, ROM, and RAM.

[Effects] As is clear from the above description, the present invention includes an image data input means, an image data storage means, and an image recording means, and the image data storage means is provided with a recording start position corresponding to the size of the recording paper. By memorizing multiple M! with an extremely simple structure! Accordingly, it is possible to provide an image recording apparatus at a low cost that can arbitrarily determine a recording start position according to the size of recording paper of the same type.
