Abstract

PURPOSE:To change over the states of printing of roll paper and sheet paper easily by changing over the direction of a hammer while being interlocked with a roll paper holder in the electronic apparatus enabling printing to both roll paper and sheet paper. CONSTITUTION:A holder 6 is extended under the state of printing to roll paper 7, and the hammer 16 is brought to a horizontal state. When printing is changed over to printing to sheet paper 8, however, roll paper 7 is removed from the holder 6, and the holder 6 is turned so as to be brought to a vertical state. Accordingly, a gear 28 formed to a holder bearing section is rotated, the revolution is transmitted to a gear 24 shaped to the shaft of a solenoid through gears 26, 25, and the hammer 16 is changed over to a vertical state, the state of printing to sheet paper 8.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electronic device with a printing device (2 types, more specifically, a roll-shaped printing paper and a sheet-shaped printing paper placed on a desk (; The present invention relates to an electronic device with a printing device configured.

Conventionally, electronic devices with printing devices, such as electronic desktop calculators (hereinafter referred to as calculators), have been known, which are configured to print on both roll-shaped printing paper and sheet-shaped printing paper placed on a desk bench. It is being Conventional electronic devices having such a structure are shown in FIGS. 1 to 4 (2).

That is, Fig. 1 explains the overall structure of a calculator with a printing device.The calculator shown by reference numeral 1 in the figure is provided with a keyboard section 2 on the upper surface of its right half for performing various key operations. An arithmetic circuit, a power supply device, and the like are housed inside the keyboard section 2 . A display 3 is provided on the upper surface of the keyboard section 2 and the left half of the calculator 1, which is one level higher than the other, to show input values, calculation results, and the like.

Further, an opening 4 is formed at the rear of the left half of the calculator 1, and a paper cutter 5 is installed in this opening 4 in an inclined state, and the rear end 1 of the calculator 1 is generally cut off. A roll paper 1 is mounted on a roll paper holder 6. The leading end of the roll paper 1 is drawn into the main body from the rear end of the calculator 1, passes between the opening 4 and the blade 5a of the paper cutter 5, and is led to the outside C2.

On the side of the opening 4, a switching lever 9 for switching printing between roll paper 7 and sheet paper 8 is provided.

The one indicated by the symbol 10 is the power switch 1. The symbol 11a is the power switch.
The mark indicated by llb is a mark for confirming the digit spacing and line position when printing on the sheet paper 8. The symbol 8a is the character printed on the sheet paper 8, and the symbol 8b is the putty mark for the printed line.

A printing device as shown in FIGS. 2 to 4 is accommodated within the calculator 1.

That is, the printing device 12 has a hollow type ring 13, and a type belt 14 made of an elastic member is attached to the outside of the type ring 13, and each type belt 14 carries type characters 14 at a predetermined pitch in the circumferential direction. It is set in. A plurality of solenoids 15 are provided inside the type wheel 13 in correspondence with each type belt 14, and each solenoid 15 is provided with a hammer 16, respectively.

Each solenoid 15 is operated as shown in FIG.
operation (gear 19 and solenoid 15 integrated with this from the second
By meshing with a gear 18 provided on a rotating shaft 17, the orientation of the hammer 16 can be switched between a horizontal state shown in FIG. 2 and a vertical state shown in FIG.

The reference numeral 20 is a platen, and the reference numeral 21 is an ink roller.

Reference numeral 22 indicates an insertion opening for the roll paper 1, and rollers 23, 23 for supplying the roll paper are provided inside the slot.

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 i 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 zero printing is performed on the roll paper 1 and the sheet paper 8. Adopting this structure has the following disadvantages:

□ That is, when the hammer 16 is rotated vertically downward from the operating port of the switching lever 9 to print on the sheet paper 8, the type ring 13 that performs printing slightly protrudes from the opening provided on the back side of the main body. (= Because it is arranged, sheet paper 8
When printing on a sheet of paper 8, if the calculator 1 is placed on the sheet paper 8, the printing position will become unclear in appearance, making it difficult to print at a predetermined printing position.

Therefore, on the side of the calculator 1 shown in FIG.

However, since the note mark lla is also provided with a side number on the side of the roll paper 7 of the calculator 1, if an attempt is made to determine the print position using this mark 11a, the field of view will be obstructed. For this reason, when printing on a sheet of paper 8 on a desk, the roll paper 7 is usually removed from the holder 6, and the holder 6 is often stored on the main body side of the calculator 1.

As a result, when switching from printing on roll paper 7 to printing on sheet paper 8, first remove roll paper 1 from holder 6, then store holder 6 into the main body, and operate switching lever 9. Therefore, the hammer 16 is rotated vertically, and the mark lla, 1lb is placed at a predetermined printing position on the sheet paper 8 (second position), and printing is performed by operating the keyboard 2, which makes the work extremely complicated. There are drawbacks.

The present invention has been made in order to eliminate the above-mentioned drawbacks of the conventional technology.The present invention has been made in order to eliminate the above-mentioned drawbacks of the conventional technology. ; The purpose is to provide an electronic device with a printing device configured.

In order to achieve the above objects, the present invention adopts a structure in which the direction of the hammer can be switched in conjunction with the roll paper holder.

FIG. 5 and subsequent figures illustrate one embodiment of the present invention. In each figure, the same parts as in FIGS. 1 to 4 are denoted by the same reference numerals, and the explanation thereof will be omitted.

In this embodiment, as shown in FIG.
6 is abolished, and the gear 2 is attached to the shaft 27 in the bearing part of the holder 6.
8 was established.

A gear 24 is fixed to the rotating shaft 17 of the solenoid li5, and intermediate gears 25 and 26 are provided between the gear 28 and the rotation of the gear 28 caused by the rotation of the holder 6.
It adopts a structure that is linked to the rotation of 5.

Therefore, in the printing state on the roll paper 7, the sixth
As shown in the figure, the holder 6 is extended, and the hammer 16
is in a horizontal state.

When you have finished printing on the roll paper and want to switch to printing on the sheet paper 8, remove the roll paper 1 from the holder 6 and rotate the holder 6 to the vertical position as shown in Figure 7. , gear 27 rotates, gear 2
The rotation is transmitted in the order of 6, 25, and 24, and the hammer 16 is in a vertical state, that is, the printing state for the sheet paper 8 (: switched).

If it is desired to print on the roll paper 7 again, the operation described above can be performed in the exact opposite manner.

As is clear from the above description, according to the present invention, the printing hammer can be switched in conjunction with the storage operation of the roll paper holder, and the printing state for a single sheet of paper can be switched extremely easily. This has the excellent effect of making the operation extremely simple and easy to use, without requiring an extra switching lever or the like.
