Description

DETAILED DESCRIPTION OF THE INVENTION The present invention replaces the bead operation of solo pan with the on/off operation of switches arranged at each bead position, and keeps the light emitting elements arranged at each bead position blinking in accordance with the on/off of the switch. This paper relates to a Solopan-type electronic computer that can be used to

Conventionally, electronic computers that operate using a numeric keypad are advantageous for multiplication, division, and other complex calculations, whereas solopan, which calculates by raising and lowering beads, has a structure and calculation method that has not been refined over many years.
Although excellent effects can be obtained in practical applications where addition and subtraction are frequently used, there are the following drawbacks.

(1) The solo pan bead is easily misplaced due to its nimble up-and-down movement, making it easy to miscalculate.

(2) Holding a solo pan requires horizontal stability.

(3) "Gobankan" is for one movement of the calculator's clear key.
Two operations are required: upper and lower payments.

In addition, calculations for multiplication and division require a considerable amount of practice, so there is a tendency in recent years for electronic computers to be used for addition and subtraction as well, although they are still inconvenient.

The object of the present invention is to replace the bead of a solopan with a switch, and to create a solopan type that can turn on/off the switch corresponding to the bead operation (thereby causing the light emitting elements such as LIEDs and g! crystals arranged at the bead position to blink and hold. The object of the present invention is to eliminate the above-mentioned drawbacks of the prior art by providing an electronic computer.

Next, the configuration of a first embodiment of the present invention will be explained with reference to FIGS. 1 to 7.

For example, as shown in FIG.
On the board, solo pan type operation bead switches corresponding to beads, hereinafter simply referred to as bead switches 2, are arranged corresponding to the bead position 1 of the solo pan, as well as a clear key 6° for canceling operation errors and calculation results. A power switch 4 is formed on the right side of the board, and as shown in FIG. 2, the switch 2 is composed of 1st to 5th place beads, and
The operation result of the bead in Fig. 2 is 1 as shown in Fig. 3. For example, when the number 257 is set, the bead switch 2 is inside the sphere.
The internal light emitting element 5 can display the result by lighting up the 1st to 3rd digits, and the structure of the bead switch 2 for each bead is the same as the seesaw set shown in Fig. 4 and the slide shown in Fig. 5. It is structured like the formula.

Next, an electric circuit for controlling the mechanism will be explained with reference to FIGS. 6 and 7.

After turning on the power switch 4 installed on the right side of the solo pan body 1, the control circuit receives signals from the bead switch 2 and clear key 3 arranged in a V arrangement on the tabletop electronic solo pan body 1. Since the calculation result is displayed on the light emitting element 5 based on the calculation operation, the input information generated by the conduction of the contacts 6a and 6b incorporated in the bead switch 2 is taken in by the C-MOS logic 7, and the further processed result is output information. Send to the LBD driver 8 and the LE
The light emitting element 5 of D is driven to display the calculation result.

That is, as shown in FIG. 7, the input information of the bead switch 2, for example, as shown in this embodiment, for the bead switch block of maximum 7 digits, "2" is entered in the first digit (100th place) in decimal notation.

Since the base of C1815) 8 is set to high (H), the driver turns on and lights up the light emitting element 5 corresponding to the first-placed bead.

Therefore, the first digit (100th place) is in a state where "3" is written.

Next, in the second digit (10th place), in order to enter 1'5'', first place the 5th place bead, then press the bead switch 2 downwards (S side) and it will be J-K corresponding to the 5th place bead. Change the CP line of F/F1Q from high (H) to low (L) to connect the J-K F/F.
'Return the output Q of 1Q from low (L) to high (H) and connect it to the LED driver (2SC1815) 8 through the resistor R.
By setting the base to high (H), the driver 8 is turned on and lights up the light emitting element 5 corresponding to the fifth place bead.

Next, in the third digit (1st place), in order to place “7”, we start with 2.
Turn on the first place bead, then the fifth place bead, or turn on the second place bead and the fifth place bead at the same time.
When the bead is turned on, the operation of the second place bead is the same as for the first digit, when the bead switch 2 is pushed upwards (S side), the AND gate 9 (
By setting one gate of TC4073) to low (L), the CP line of J-K F'/PI Q corresponding to the switch 2 is changed from high (H) to low (L).
