To 35a may be performed by an image sensor or a photosensor array that recognizes the pattern.

However, as in the case of the on-vehicle printer 1 of this embodiment, a single fixedly arranged pattern detecting sensor 17 is provided.
, The identification patterns 31a to 35a
This is advantageous because the receipt paper 31, the use paper 33, and the ticket paper 35 can be identified relatively inexpensively.

The identification patterns 31 a to 35 a of the receipt paper 31, the use paper 33, and the ticket paper 35 by the pattern detection sensor 17 are determined by the papers 31 to 35.
It may be performed at a position other than the cue position of 35.

However, if the identification patterns 31a to 35a are identified at the cue positions of the papers 31 to 35 as in the vehicle-mounted printer 1 of the present embodiment, the receipt paper 31 and the usage paper 33, it is not necessary to perform cueing of the sheets 31 to 35 separately after the ticket sheets 35 are identified, so that the feed control of the feeder 11 accompanying the printing operation is simplified and the printing operation is smoothly performed. So it is advantageous.

Further, the sheets 31 to 31 inserted in the sheet feeding port 5a are
The output of the error sound from the speaker 15 due to the pressing operation of the issue switches 7a to 7c which does not correspond to 35 may be omitted, but if the configuration is made to perform this as in the vehicle-mounted printer 1 of the present embodiment, Paper 31 to 31 inserted in paper feed port 5a
The pressing operation of the issue switches 7a to 7c not corresponding to 35 can be notified not only in the visually recognizable form of forced ejection of the sheets 31 to 35, but also in the auditory recognizable form. Is advantageous.

Further, in the vehicle-mounted printer 1 of the present embodiment, in order to identify the receipt paper 31, the utilization paper 33, and the ticket paper 35, the black edges 31b , 31d, 33b, 33d, 35b
In addition, the identification patterns 31a to 35a constituted by the combination of these and the white portions 31c and 33c are printed in advance as the type identification patterns.

However, the formation location of the type discrimination pattern is not limited to the left edge of the sheets 31 to 35, and is arbitrary. The type discrimination pattern is not limited to a dedicated mark or the like.
It is needless to say that characters, frames, lines, figures, and the like necessary for appearance of the papers 31 to 35 may be used, which are printed in different places depending on the papers 31 to 35.

In this embodiment, the taxi-mounted printer 1 connected to the taxi meter 21 has been described as an example. However, the present invention is not limited to the taxi-mounted vehicle-mounted printer 1 used by a driving agency. It goes without saying that the present invention can be widely applied to various in-vehicle printers used in vehicles such as printers.

As described above, according to the in-vehicle printer of the present invention, the charge is calculated by the charge calculation meter in accordance with the operation of the type designation switch for designating the type of the loaded paper. In the vehicle-mounted printer that prints the printing information corresponding to the type specified by operating the type specifying switch on the loaded paper based on the information such as the fee, the form is changed for each type of the paper. A pattern reading unit that reads a type determination pattern formed in advance on the sheet from the loaded sheet; and the type determination pattern read from the loaded sheet by the pattern reading unit is the type designation switch. A type correspondence determining unit for determining whether or not the type corresponds to the type specified by the operation; and When the type discrimination pattern read from the paper does not correspond to the type specified by the operation of the type specifying switch, when the type correspondence determination unit determines, the type specified by the operation of the type specifying switch is determined. Paper forcibly discharging means for discharging the loaded paper without printing the corresponding print information.

For this reason, even when the type designation switch corresponding to the type different from the type of the loaded paper is erroneously operated, the type corresponding to the type designation switch operated erroneously is determined. It is possible to prevent print information from being printed on paper of a different type, and to correctly print a receipt of a desired type on a paper corresponding to the type.

According to a second aspect of the present invention, in the in-vehicle printer according to the first aspect, the pattern reading means specifies the type of the loaded sheet by the type designation. A determination feeding means for feeding an amount corresponding to the type specified by the operation of the switch; and a fixedly disposed at a position facing the loaded sheet after being fed by the determination feeding means; Mark detection means for detecting a mark constituting the type discrimination pattern on the loaded paper portion facing the paper, and a type on the paper portion facing the mark detection means based on a detection result of the mark detection means. And a designation type pattern discriminating means for discriminating the discriminating pattern.

For this reason, the place where the mark constituting the type discrimination pattern is formed on the sheet in advance is made different for each sheet type in the sheet feeding direction by the judging feed means, or the mark is formed for each sheet type. By forming or not forming on the paper, it is determined whether the loaded paper corresponds to the type specified by operating the type specifying switch based on the mark detection result by the pattern reading unit. The determination can be made with certainty.

According to a third aspect of the present invention, in the in-vehicle printer according to the second aspect, the print position of the print information is located on the sheet by feeding. A cue position detection mark for performing the loading operation is formed in advance, and the loaded paper is fed by the determination feeding means in an amount corresponding to the type designated by operating the type designation switch. The print position of the print information on the printed sheet is searched for.

For this reason, in order for the type correspondence determining means to determine whether or not the loaded paper corresponds to the type specified by operating the type specifying switch, the type specifying means of the pattern reading means performs the type specification. By feeding the loaded paper in the amount corresponding to the type specified by the operation of the switch, the cueing of the paper to the printing position of the print information corresponding to the type specified by the operation of the type specifying switch is simultaneously executed, The time required until the start of printing the print information can be shortened, and the processing can be simplified.

According to the in-vehicle printer of the present invention described in claim 4, in the in-vehicle printer of the present invention described in claim 1, 2 or 3, the paper loaded by the pattern reading means is used. If the read type determination pattern does not correspond to the type specified by operating the type specifying switch, the type corresponding determination unit determines that the type of the loaded paper and the operation of the type specifying switch And a notifying unit for notifying that the type does not match the specified type.

For this reason, when the type designation switch corresponding to the type different from the type of the loaded paper is erroneously operated, the print information corresponding to the type corresponding to the erroneously operated type designation switch is transmitted. In addition to preventing printing on paper of a different type, the type of switch that specifies a type that does not correspond to the type of loaded paper has been operated, so that the notification means can reliably recognize that the type switch has been operated. Can be done.
