JPH1166521A - Cleaning sheet for magnetic head and transfer portion in magnetic card reader - Google Patents

Abstract

PROBLEM TO BE SOLVED: To easily and quickly eliminate adhered contamination and dust without damage on magnetic head and transfer member and disassembling a device by providing an weak adhesive layer consisting of urethane resin based adhesive agent having a particular adhesive force to both surfaces of a substrate in the same size as a magnetic card. SOLUTION: A weak adhesive layer 2 formed by coating of urethane resin based adhesive material having the width of 25 mm and an adhesive force of 50 to 600 g for the peeling in the 180 degree is provided in both surfaces of a substrate 1 in the same size and thickness as a magnetic card for automatic reader in order to form a cleaning sheet 3. For example, when the cleaning sheet 3 from which the stripping sheet 4 is stripped from both surfaces thereof is inserted to a ticket inserting port of an automatic ticket checker, the ticket is transferred by a roller and a belt conveyer, etc., provided at the entrance thereof, it passes through a magnetic head and it is then transferred to the exhausting port. During this process, contamination or dust adhered to the transferring means and magnetic head can be eliminated by a weak adhesive layer 2. The cleaning sheet 3 may be used repeatedly with lower maintenance cost.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnetic head portion in a device having a magnetic head for automatically reading a magnetic card, such as a public telephone, an automatic teller machine of a financial institution, a cash dispenser or an automatic ticket gate at a station. And rollers,
The present invention relates to a cleaning sheet capable of removing dirt and dust on a conveying portion such as a belt conveyor.

[0002]

2. Description of the Related Art Conventionally, in a device equipped with a magnetic head for automatically reading a magnetic card, such as a pay phone, an automatic teller machine at a financial institution, a cash dispenser, or an automatic ticket gate at a station, these devices are periodically removed. It was disassembled to remove dirt and dust from the magnetic head part, rollers, and conveyor parts such as a belt conveyor.

[0003]

As described above, if the equipment is periodically disassembled to remove dirt and dust from the magnetic head, rollers, and belt conveyors, it takes a long time to complete the work. Therefore, there is a problem that the maintenance fee becomes very expensive.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and is intended to provide a device having a magnetic head for automatically reading a magnetic card, such as a public telephone, an automatic teller machine, a cash dispenser, an automatic ticket gate, and the like. An object of the present invention is to provide a magnetic card reader and a cleaning sheet for a transporting part in a magnetic card reader that can remove dirt and dust on a transporting part such as the magnetic head part, rollers, and a belt conveyor very easily without disassembly. Is what you do.

[0005]

According to the present invention, two substrates are provided on the upper and lower surfaces of a substrate having the same size and thickness as a magnetic card.
The problem has been solved by adopting a means of providing a weak adhesive layer coated with a urethane resin-based adhesive having an adhesive force of about 50 to 600 g when peeled at a width of 5 mm and 180 degrees.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described in detail with reference to the drawings. A telephone card for a public telephone, an automatic teller machine of a financial institution, a cash card for a cash dispenser or an automatic ticket gate. 25m on the upper and lower surfaces of the board 1 of the same size and thickness as the ticket or commuter pass for use, and the magnetic card for other automatic readers
A cleaning sheet 3 is formed by providing a weak pressure-sensitive adhesive layer 2 coated with a urethane resin-based pressure-sensitive adhesive having an adhesive force of about 50 to 600 g when peeled at an m width of 180 degrees.

[0007] In the figure, reference numeral 4 denotes a release paper adhered and fixed to the weak adhesive layer 2 in a releasable manner.

[0008] Thus, the cleaning sheet 3 having the above configuration
When the cleaning sheet 3 is peeled off from the release paper 4 and inserted from, for example, a ticket insertion slot of an automatic ticket gate, the cleaning sheet 3 is sandwiched by rollers at the entrance, dragged and sent forward by a belt conveyor, and provided in the middle thereof. The magnetic head is fed to the take-out port through which the dirt or dust adhering to the transport portion such as a roller or a belt conveyor and the magnetic head portion adheres to the weak adhesive layers 2 on the upper and lower surfaces of the cleaning sheet 3. Remove at least. By preparing and inserting a plurality of cleaning sheets 3, dirt and dust can be sequentially removed from the entrance to the take-out opening.

The weak adhesive layer 2 to which the dirt and dust are adhered can be further used by wiping with a wet cloth or wet tissue or washing with water without impairing the adhesive strength.

The usage of a public telephone, an automatic teller machine, a cash dispenser, and other devices equipped with a magnetic card reader other than the automatic ticket gate is the same as that of the automatic ticket gate.

Since the weak adhesive layer 2 has a weak adhesive force, the adhesive does not adhere to a transport portion such as a roller or a belt conveyor or a magnetic head portion, and there is no fear of damaging them.

[0012]

Since the present invention is as described above, it is possible to disassemble a device having a magnetic head for reading a magnetic card, such as a public telephone, an automatic teller machine, a cash dispenser, an automatic ticket gate, etc. By using exactly the same operation as inserting a magnetic card, dirt and dust adhering to them can be removed very easily and quickly by attaching them to a weak adhesive layer without damaging the magnetic head portion and the transport portion of the device. As a result, there is little maintenance fee compared to the past, and the weakly adhesive layer can be used again without losing the adhesive strength by removing dirt or dust attached by wiping with a wet rag, wet tissue, etc. In addition, the cleaning sheet of the present invention can be manufactured at low cost.
