Abstract
The utility model relates to a memory module of an electronic cash register, which belongs to the technical field of electronic storage. The electronic cash register provided by the utility model comprises a memory chip, a PCB and an interface circuit. The memory chip is connected with the PCB through the interface circuit, and the side edge of the PCB is connected with an interface terminal. In the utility model, the electronic cash register is inserted into the main board of the fiscal cash register in a socket connector mode for use; and the utility model has the following beneficial effects: the memory chip containing vital data is independently kept and connected with the main board through a plug connector; when breakdown occurs, the memory chip containing vital data can be removed conveniently and rapidly so as to ensure the safety of vital data, data loss caused by adopting inappropriate removal mode can be avoided, an ordinary maintenance man can fulfill the maintenance, and the resource is saved while the maintenance efficiency is improved, thereby facilitating the use of consumer.
Description
Technical field
The utility model relates to a kind of memory module of electronics Cash collecting equipment, belongs to the electronics technical field of memory.
Background technology
At present, the inside of electronics Cash collecting equipments such as electronic cash register on the market, tax-control cash register, commercial POS machine has at least one pin-saving chip, writing down user's all kinds of significant datas such as business data, tax data in the storage chip, this storage chip is integrated in the mainboard, along with user's increase of service time, the Various types of data of storing in the storage chip day by day increases, these data to user's follow-up operation, advance paying of pin data query, tax and all play important effect.All inevitably can produce some faults as all electronic equipments, the electronics Cash collecting equipment is no exception, makes a big impact for user's normal use even loses.And when the electronics Cash collecting equipment, the tax control mainboard of tax-control cash register particularly, when promptly storing the fault of integrated circuit board generation more complicated of tax data, business data, the maintenance personal can't repair the fault machine immediately, the common operation of maintenance personal is that the fault machine is taken back producer in this case, and the user can only use guest machine or manual bill to continue business, and the user just can continue to use former machine billing after producer is original subscriber's machine reparation.For the machine of taking back maintenance, the research staff of producer is in the time also can't repairing fault through careful inspection and maintenance, especially under the situation that system can't start, in order to save the significant data of machine intimate, the pin-saving chip that is welded on the mainboard need take off with specific purpose tool or electric soldering iron in producer, be welded to new mainboard again and get on, change former fault mainboard, to reach the purpose of repairing machine with the new mainboard that welds the storage chip that stores original subscriber's data.Handle like this and have following drawback: the maintenance of machine needs the technician of producer to participate in debugging directly usually, and maintenance cycle is long, is not easy to user's use; The tax-control data, the business data that are stored in machine intimate have also increased in maintenance, transportation to be lost, damages, and the chance of destruction is brought irreparable damage to the user.
The utility model content
The purpose of this utility model is the defective that exists at above prior art, and a kind of memory module that is used for the electronics Cash collecting equipment is provided, and this memory module can be for convenience detach, can recover significant data within a short period of time.
The purpose of this utility model is achieved through the following technical solutions: the detachable memory module of electronics Cash collecting equipment, comprise storage chip, pcb board and interface circuit, described storage chip is connected with pcb board by interface circuit, and the side of described pcb board is connected with Interface Terminal.Described storage chip is welded on the pcb board.The equal connecting interface terminal in the both sides of described pcb board.Contain signal pins pipe and data pin pipe on the described storage chip, described signal pins pipe is connected with interface circuit.
The beneficial effects of the utility model are: the storage chip that will contain significant data is independently preserved and the mode by plug connector links to each other with mainboard, can make things convenient for the safety that promptly thereby its dismounting is guaranteed significant data when breaking down, the loss of data of having avoided dismantling mode improperly and being caused, common maintenance personal can finish maintenance, also improved maintenance efficiency when economizing on resources, be user-friendly to.

Embodiment
Embodiment one
As depicted in figs. 1 and 2, device of the present utility model comprises: a pcb board 3, weld storage chip 1 and storage chip 2, the equal connecting interface terminal 4 in the both sides of pcb board by interface circuit on the pcb board 3. Storage chip 1 and 2 adopts K9F5608 flash memory and FM24C256, and the signal pin on the chip is connected with interface circuit, and links to each other with CPU on the tax-control cash register mainboard by interface circuit, and realization CPU is to the controls such as read-write of storage chip; Data pins on the storage chip then directly goes up corresponding data pins with CPU and is connected, and realizes the transmission of tax-control data.Come down to control, reach the purpose of the data in the storage chip of reading and writing and control this memory module by the CPU interface circuit of tax-control cash register mainboard.Storage chip itself and interface circuit thereof all are arranged on the pcb board, whole form a tax control data storage card, and the form by connector is inserted on the mainboard of tax-control cash register and uses.
When catastrophic failure appears in the tax-control cash register mainboard, do not need directly to change tax-control cash register, and only need be extracted this significant data memory module by hand, and be plugged in the new mainboard and just can reuse, save time, save trouble, the reliable guarantee that provides convenience also to provide for maintenance for user's significant data.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
