PURPOSE:To increase the using efficiency, by realizing both operations by one man and two men for an electronic cash register and automatically switching these two systems of operation each other in accordance with the time. CONSTITUTION:A register is operated by one man out of a specific time band. A discriminating means 20 delivers a low-level signal to shut off an AND gate 21. While the output signal of the means 20 is set at a high level via an inverter 22, and accordingly a gate 23 is made operable. The register is operated by two men within the specific time band. The means 20 delivers a high-level signal to turn on a gate 11. On the other hand, the output signal of the means 20 is set at a low level, and accordingly the gate 23 is made inactive. The transaction information is transferred to a buffer register 24 at an adjustment part B. At the same time, a key input 25 receives an adjustment process 27 via a key encoder 26 to be displayed 28 and printed 29. |
