BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to a printing apparatus for use with portable terminals, measuring instruments, etc., and more particularly, to a printing apparatus equipped with a paper cutter having a function of cutting recording paper after printing.
BACKGROUND OF THE INVENTION
There has been an increased demand in recent years for printing apparatuses, used in conjunction with portable terminals, numerous kinds of measuring instruments, etc., that are equipped with a paper cutter capable of automatically cutting recording paper after printing, in addition to a demand for a reduction in their sizes, and weights, as well as in the thicknesses.
A printing apparatus equipped with a paper cutter of the kind as shown in FIGS. 18A, 18B and 18C is generally known. That is, FIG. 18A is a typical side view depicting an outline of a printing apparatus equipped with a paper cutter of the prior art, FIG. 18B is a plan view depicting an outline of a cutter unit, and FIG. 18C is a plan view depicting an outline of a printer unit.
In the drawings, a printer unit I is a portion that prints on a recording paper 2, and it comprises a platen roller 3 for feeding paper, a printer motor 5 for driving the platen roller 3 via a series of gears 4 and a printer head 6 for printing on the recording paper 2. A cutter unit 7 is a portion that cuts the recording paper 2 after printing, and it comprises a stationary blade 8, a movable blade 9 and a cutter motor 11 for moving the movable blade 9 toward the stationary blade 8 via a gear 10.
With the above structure, the recording paper 2 is transferred by the platen roller 3, guided to an exit port (not shown in the drawing) after being printed on by the printer head 6, and the recording paper 2 is cut by snipping the recording paper 2 with the stationary blade 8 and the movable blade 9.
However, since in a majority of the printing apparatuses known in the past, the recording papers have been cut by hand after printing, whether the cutter unit 7 is attached or not has depended on the request of the user in most cases. For this reason, the cutter unit 7 has merely been a device that is selected according to a width of the papers and is placed upon the printer unit 1, if one is to be attached.
Therefore, there is a limitation in reducing the size, weight and thickness of the printing apparatus equipped with a paper cutter. With regard to the reduction of thickness in particular, it is impossible to make it equal to or below the thickness of the printer motor 5 and the cutter motor 11.
SUMMARY OF THE INVENTION
The present invention resolves the above-cited problems, and aims at providing a printing apparatus equipped with a paper cutter which is small, light and thin, and with a considerably simple structure.
In order to achieve this object, a printing apparatus equipped with a paper cutter of the present invention is so constructed that a portion of a motor fits in a space provided adjacent to the other motor when a cutter unit and a printer unit are assembled in a stack. With this structure, either each of the motors or one of the motors are able to utilize efficiently the spaces or space available adjacent to each or the one of the motors, thereby providing a printing apparatus equipped with a paper cutter which is small, light and thin, and with a considerably simple structure.
