Cash box inspection device and cash register system

Abstract

The invention provides a cash box inspection device and a cash register system, which are used for inspecting the opening state of the cash box. The device comprises an arithmetic logic circuit and a switching element, wherein the arithmetic logic circuit is provided with a first input end, a second input end and an output end, wherein the first input end and the second input end are respectivelycoupled with a micro-active switch, and high level voltage is respectively inputted into the first input end and the second input end. When the first input end and the second input end are provided with the same logic voltage level, the output end outputs a first logic level; and when the first input end and the second input end are provided with different logic voltage levels, the output end outputs a second logic level. The switching element is coupled between an electromagnetic switch and the first input end. The invention can remind a user of assuredly monitoring the actual state of the cash box.

Description

technical field [0001] The invention relates to a detection device, in particular to a detection device for detecting the opening and closing state of a cash box. Background technique [0002] For merchants, most of the current money collection is done electronically, for example, a cash register system (point-of-sale, POS) is a commonly used electronic product. Such as figure 1 Shown is a typical cash register system, which at least includes a control host 1 and a cash box 2, wherein the control host 1 mainly provides basic functions such as commodity price input, amount calculation, printing receipts, and amount display. The automatic opening of the cash box 2 is controlled electronically, so that money can be deposited or taken out from the cash box 2 . [0003] according to figure 1 The disclosed cash register system, its internal functional blocks are shown in Figure 2. In FIG. 2, the control host 1 controls the display unit 13, the operation unit 15, and the printi...
