Abstract

An apparatus for measuring the lifespan of a key input unit of an ATM(Automatic Teller Machine) is provided to measure the accurate limited life by making a reciprocating part repetitively come in contact with the key input unit and properly buff the power pressurized on the key input unit. A reciprocating part(300) repetitively comes in contact with a key input unit in order to measure the lifetime of the key input unit(2). The controller controls the driving of the reciprocating part, and receives a sensing signal of a contact detection sensor equipped in the key input unit to count the contact times. The reciprocating part comprises a piston(330), an elastic spring and a pressing member(350). The piston is elevated up and down by the compressed air. The pressing member is combined to a spring insertion portion together with the elastic spring. The holding member elastically comes in contact with the key input unit.

Description

Device for measuring the lifetime of key input of financial automation equipment {Device for measuring durability of keypad in A.T.M}

The present invention relates to an apparatus for measuring lifetime of a key input unit of an automated teller machine, and more particularly, to an apparatus for measuring lifetime of a key input unit of a teller machine capable of measuring a limit life by repeatedly pressing a key input unit provided in an automatic teller machine. It is about.

In general, financial automated devices, which are devices developed to provide services without consulting services without any time constraints, are included in banknote machines and bank machines. It is a device that is developed and used from the initial stage for business computerization, and it is a device that can automatically withdraw the stored bills, and a banknote deposit and withdrawal device is also equipped with a deposit function.

1 is a perspective view showing a general automatic teller machine.

Referring to FIG. 1, the mainframe 1 of the automated teller machine is provided with a key input unit 2 as an interface for receiving a user's financial transaction command or request.

The key input unit 2 includes a plurality of key buttons 2a related to each financial transaction. The key buttons 2a include, for example, deposits, withdrawals, balance inquiries, transfers, and 1 to 9 including 0. Arabic numerals may be provided.

The key input unit 2 is installed in an easy part of the main frame 1 so that a user who uses the device is easy to operate, and is composed of a mechanical or contact button. In this case, since the key input unit 2 is a component that is frequently contacted, the key input unit 2 may be manufactured to be suitable for the installation environment only when it is expected to be able to operate properly in accordance with its use environment.

2 and 3 is a block diagram showing the life measurement device of the key input unit of the conventional automatic teller machine filed by the applicant of the patent application No. 10-2005-0135832.

2 and 3, the conventional key input unit lifetime measuring apparatus 10 is installed in the variable jig 20 so as to measure the life of the key input unit 2 and repeatedly contacted with the key input unit 2. Reciprocating means 30 and the control unit 50 for driving control of the reciprocating means 30 and receiving the detection signal of the touch sensor 2b provided in the key input unit 2 to count the number of times of contact; Is done.

In this case, the reciprocating means 30 is a piston 33 reciprocated within a predetermined stroke range by the compressed air supplied through the two air supply ports (32a, 32b) formed in the cylinder body 31, The pressing member 35 is formed at the end of the piston 33 and repeatedly contacts the key button 2a.

The controller 50 sequentially supplies compressed air to the air supply port 32 of the cylinder body 31 so that the piston 33 linearly reciprocates in the cylinder body 31, and thus the specific key of the key input unit 2. Contact non-contact is repeatedly performed to the button 2a.

The conventional life-time measuring device 10 is such that the reciprocating means 30 repeatedly operates for a predetermined period of time and acquires a counted contact count when no more key values are transmitted to the control unit 50 to measure the limit life. do.

However, the pressing member 35 coupled to the reciprocating means 30 has no cushioning means at the end of the reciprocating piston 33, so that the force to operate the piston 33 remains at the key button 2a. It is delivered.

In this case, in the process of measuring the life span of the key input unit 2, the key button 2a is pushed beyond the force of a normal user, so that the life measuring device 10 or the key input unit 2 is broken and the correct limit is reached. There is a problem that it is difficult to obtain a lifetime measurement.

The present invention has been made to solve the above-described problems, the reciprocating means is repeatedly contacted with the key input unit of the automatic teller machine, the reciprocating means can be accurately measured by limiting the appropriate force to press the key input unit life The purpose of the present invention is to provide a lifetime measuring device for a key input unit of a financial automation device.

Key input unit life measurement device of the automatic teller machine of the present invention for achieving the above object,

A reciprocating means repeatedly contacted with the key input unit so as to measure the life of the key input unit, and a control unit for driving the reciprocating unit and counting the number of touches by receiving a detection signal from the touch sensor provided in the key input unit. An apparatus for measuring the lifetime of a key input unit of an automatic teller machine, the reciprocating means comprising: a piston which is reciprocated vertically by compressed air and has a spring insertion portion formed therein; An elastic spring inserted into the spring insertion unit; And a pressing member coupled to the spring insertion part together with the elastic spring and repeatedly pressed to elastically contact the key input part. Characterized in that comprises a.

In addition, the pressing member is characterized in that formed of a rubber material.

In addition, the variable jig is provided with a plurality of guide rails in the X, Y-axis direction, the guide rail is characterized in that a plurality of the reciprocating means is further installed.

In the apparatus for measuring the life of the key input unit of the automatic teller machine according to the present invention, the reciprocating means is repeatedly contacted with the key input unit of the automatic teller machine, and the accurate limit life is measured by appropriately buffering the force applied by the reciprocating means to the key input unit. There is an advantage to this.
