Abstract

PURPOSE:To enable a rolled from recording paper with a roll diameter larger than the size of a casing to be used even where the casing is a portable-type thin form one, by a construction wherein a rolled from recording paper with a roll diameter larger then that of a rolled form recording paper to be contained in a casing cab be placed on a recording paper holder drawn out from the casing. CONSTITUTION:The recording paper holder 11 for containing the recording paper 12a or 12b is fitted to the casing 10, and can be slidden in the directions of arrows B. A bendable connecting part 18 is bent so that the calculator is easily portable. When using the recording paper 12a with a smaller roll diameter, a key inputting part 17 is extended flat, and keys are operated, and a printer 13 is actuated to record. When using the recording paper 12b having a larger roll diameter as supplement to the recording paper 12a, the recording paper holder 11 is drawn out in the direction of the arrow B, the paper 12b is fitted thereto, and is set to the printer 13, whereby the paper 12b can be used. When carrying the calculator after use thereof, the paper 12b is detached, the holder 11 is contained into the main body, and the inputting part 17 is bent onto the main body, whereby the calculator becomes portable.

Description

[Detailed description of the invention] Industrial applications The present invention relates to a recording type electronic desktop calculator.

Structure of the conventional example and its problems FIG. 1 is a front view of a conventional electronic desktop calculator, and FIG. 2 is a partially cutaway side view of the conventional electronic desk calculator.

1 and 2, 1 is an upper case, and this upper case 1 includes a keyboard 2. A display 3 and a print cover 4 that can be opened and closed are attached. This print cover 4 has a hole 5 formed therein for taking out the recording paper after printing. 6 is the lower case, and this lower case 6
includes a roll of recording paper 7 and a printer 8 for printing on this recording paper 7. and an electric circuit section (not shown) are attached, and the lower case 6 can be connected to the upper case 1 and its accessories.

However, in a recording-type electronic desktop calculator with such a configuration, the diameter of the roll of recording paper 7 is regulated by the lower case 6 and printer cover 4, so recording paper with a larger diameter cannot be used. There were drawbacks. In particular, the winding diameter of thin portable electronic desktop calculators is limited to an even smaller size, which has been a problem.

OBJECTS OF THE INVENTION The present invention eliminates the drawbacks of the above-mentioned conventional examples, and aims to provide an excellent electronic desktop calculator that can use recording paper with a larger diameter than the housing even if it has a thin portable housing. purpose.

Structure of the Invention In order to achieve the above-mentioned object, the present invention includes a housing in which a recording paper tray for placing recording paper for a printer is attached to the housing so as to be freely removable and removable.
When this recording paper tray is pulled out from the housing, recording paper with a diameter larger than that of the recording paper that can be stored in the housing can be placed. This has the advantage that recording paper with a larger diameter can be used.

DESCRIPTION OF THE EMBODIMENTS The configuration of an embodiment of the present invention will be described below with reference to the drawings. FIG. 3(a) is a top view of an electronic desk calculator according to an embodiment of the present invention, and FIG. 3(1)) is a top view of an electronic desktop calculator according to an embodiment of the present invention.
-A' sectional view, Fig. 4 is a partially cutaway side view of the case of recording paper with a small winding diameter in the same embodiment, and Fig. 5 is a side view with a partial cutaway showing the case of recording paper with a large winding diameter in the same embodiment. Partially cutaway side view, No. 6
The figure is a side view of the same embodiment when it is carried.

In FIGS. 3 to 6, 11 is the recording paper 12a folded or 1
21), and this recording paper tray 1
1 has a configuration as shown in FIG. 3 (1)) and is attached to the housing 10 of the electronic desktop calculator, and is slidable in the B direction. 1
3 is a printer that prints on recording paper 12ai or] 2b, 1
4 is a printer cover in which a hole 15 is formed, and this printer cover 14 is attached to the main body so that it can be opened and closed so that the recording paper 12a or 12b stored in the recording paper receiver 1 can be taken out. 16 is a display section, 17 is a key input section, and 18 is a bendable connecting section.
It is bent as shown in Figure 6, making it easier to carry.

Next, how to use the above embodiment will be explained. In Figs. 3 to 6, when carrying the electronic desk calculator, it is folded as shown in Fig. 6. Then, recording paper 12 with a small diameter
When using this electronic desk calculator according to a.
As shown in FIG. 4, the key input section 17 is unfolded and the keys are operated to operate the printer 13 to record.

To replenish the recording paper 12a, use the recording paper 12b with a large diameter roll.
When using the printer, as shown in Figures 3 and 5, pull out the recording paper receiver 1 in direction B, take the recording paper 12b of the winding diameter into the recording paper receiver 11, and attach it to the printer 13. By doing so, it becomes possible to use the recording paper [21] of the winding diameter dog.

After using this electronic desk calculator, when carrying it around again, remove the large-diameter recording paper 12b, store the recording paper receiver 11 in the main body as shown in FIG. 4, and then open the key input section 17 as shown in FIG. By folding it towards the main body, it becomes portable.

Effects of the Invention As is clear from the above-mentioned embodiments, the present invention has a recording paper tray for placing recording paper for a printer attached to a housing so as to be removable and removable, and when the recording paper tray is pulled out from the housing, Since it is configured so that recording paper with a diameter larger than the diameter of the recording paper that can be stored can be placed, even if it is a thin portable case,
This has the effect that recording paper having a larger diameter than the casing can be used.
