In order to solve the above-mentioned problems, a vehicle-mounted printer according to the present invention has a roll paper storage section having an opening on the upper surface and storing a print roll paper therein, And a cover provided with a printing section for printing on the roll paper and a lever for operating when a paper jam occurs by inserting the leading end of the printing roll paper into the printing section and covering the opening of the housing. And a cover having a side plate that is provided to be openable and closable and overlaps an inner wall of the housing in a closed state.

In order to solve the above-mentioned problems, an in-vehicle printer device according to the present invention is provided with an operation projection provided inside a cover for setting a lever to a printing position by closing the cover.

With the above configuration, when the cover covering the opening of the housing is closed, both side plates of the cover overlap with the inside of the housing, so that dust or the like is formed between the peripheral edge of the cover and the inner peripheral surface of the opening. Since there is no gap in which dust enters, it is possible to reliably prevent dust and the like from entering the housing.

Further, after the leading end of the printing roll paper accommodated in the roll paper accommodating section is accommodated in the printing section, even if the user forgets to lower the lever to the printing position, the cover is provided inside the cover by closing the cover. Since the operating projection automatically resets the lever to the printing position, it is possible to eliminate problems such as printing failure due to an operation error.
