Unisonic Xl-110 Electronic Calculator

Description
This small, printing desktop electronic calculator has an array of nine digit keys with zero, decimal and equal keys below. On the right are for keys for arithmetic functions. Right of these are reverse sign, percentage, subtotal (diamond), and total (*) keys. Immediately to the left of the digit keys are memory total, memory subtotal, memory minus, and memory plus keys. Left of these are a paper feed (up arrow) key, a non-add printing and date printing key, a clear key, and a CE (clear entry?) key. Above the keys are a decimal point selector switch, a round-off selector switch, an item count print switch, a non-print switch, and a mark up, mark down key. The power switch is on the left side.
Behind the keyboard is a ten-digit display. Behind this is a paper tape and printing mechanism. The paper tape folds forward for carrying, and back to display the results. With the paper tape open, the dimensions are 9 cm. h. x 12 cm. w. x 27.3 cm. d.
A mark in back of the display reads: Unisonic XL-110. A mark on the back reads in part: Unisonic XL-110. In both of these marks, there is an indication that Unisonic is a registered trademark. It also reads in part: SERIAL NO. 90502020 MADE IN JAPAN. A case on the right side of the bottom holds four batteries. A jack for attaching to an “AC adaptor” is at the back.
The North American Foreign Trading Corporation of New York City, N.Y., first used the trademark Unisonic in 1968 for vacuum tubes, resistors and other electronic devices. In 1972 it extended the trademark to include calculators, receiving the registration in 1975.
