is provided.

The type wheel 13 is rotated by a pulse motor (not shown), and this pulse motor is controlled by a control circuit housed in the calculator 1 to position the desired type at a printing position.

Based on the structure described above, by operating the switching lever 9, the hammer 16 is switched between the horizontal state and the vertical state, and printing is performed on the roll paper 7 and the sheet paper 8. Adopting this has the following drawbacks.

That is, when the hammer 16 is rotated vertically downward by operating the switching lever 9 to print on the sheet paper 8, the type ring 13 that performs printing is so arranged that it slightly protrudes from the opening provided on the back side of the main body. Therefore, when printing on the sheet paper 8, when the calculator 1 is placed on the sheet paper 8, the printing position becomes unclear in appearance, making it difficult to print at a predetermined printing position.

Therefore, as shown in FIG. 1, marks 11a and 11b corresponding to the printing position are provided on the side surface of the calculator 1, and the printing position on the sheet paper 8 is determined by these marks.

However, such positioning marks 11a,
11b for positioning and printing, if the printing positions on the sheet paper 8 are at a certain interval, the positioning marks 11a and 11b are used again to print the next line after printing one line. This has the drawback that the speed of the printing operation is reduced when it is desired to print continuously over a large number of lines on the sheet paper 8.

Furthermore, the printing operation energizes the solenoid 15,
The hammer 16 is made to protrude to elastically deform the type belt made of an elastic material, and the type 14a is made to protrude, and printing is performed on roll-shaped printing paper or printing paper on a sheet, but not on sheet paper 8 on a desk. The distance between the printed characters 14a and the sheet paper 8 cannot be large. This is because the amount of protrusion of the type 14a when struck by the hammer 16 is extremely small.

Therefore, with the hammer 16 in a horizontal position, the roll paper 7
Even when printing on paper, the type 14a is located extremely close to the desk top, and there are disadvantages in that ink may fall and stain the desk top or sheet paper, and the type ring may be damaged by protrusions. .

The present invention has been made to eliminate the above-mentioned drawbacks of the conventional technology, and even when printing on a roll of printing paper, the printing paper and other objects placed on the desk are stained with ink. The purpose of the present invention is to provide an electronic device with a printing device configured so that the printing wheel is not damaged by protrusions on the desk, and furthermore, it is possible to print efficiently on a sheet of paper at regular intervals. There is.

In order to achieve the above object, in the present invention, in an electronic device equipped with a printing device that can switch to a printing state on sheet paper and print by operating a switching lever, the electronic device is provided with a printing device that prints in parallel along the side edge of the electronic device. a positioning member provided with a guide groove provided, an engaging portion formed in the guide groove, and a rising portion in which a plurality of fixed groove portions are formed at a predetermined pitch, the positioning member being removable when using the electronic device; A configuration is adopted in which the electronic device is moved by clicking at the predetermined pitch by changing the fitting position between the groove portion of the rising portion of the positioning member and the engaging portion in the guide groove.

Hereinafter, details of the present invention will be explained based on embodiments shown in the drawings.
