Abstract

PURPOSE:To make a card reader body small-sized, to simplify a card carrying mechanism, and to obtain high reliability by operating the motor casing itself of a geared motor as a card carrying roller. CONSTITUTION:An inserted card 63 is carried to the right in the figure by an elastic body 64 wound round a geared motor casing, and a roller 66 energized by a pressure spring 65. After the carrying-in of the card is ended, a solenoid 68 is turned on to rotate a power transfer switching member 59 connected by a pin 69 counterclockwise, and a pawl part 59b goes into the tooth part 62a of a gear 62 to detain a rotation of the geared motor casing, and simultaneously, to disengage the mesh of the pawl part 59a and a spur gear 52 and to rotate the output shaft 51 of a geared motor counterclockwise. By the constitution of the power transfer system, a pulley 55 is also rotated in the same direction as the output shaft 51, namely, counterclockwise, and a signal read/write head 57b is driven to the left in the figure on the card 63.

Description

[Detailed Description of the Invention] The mechanism of a card league used in industrial applications such as cash cards can be roughly classified as follows: A head that exchanges signals with the card is fixed to the card league body, and the card is transported. There are two types: a card moving type in which signal processing is performed while the card is being carried in, and a moving head type in which the card is fixed at a predetermined position after being carried in and the head is moved to process the signal. The present invention relates to a head moving type card league, and is applicable to a card league having a card transport means such as a magnetic card reader and a means for reading signals from the card or writing signals to the card.

Conventional Structure and Its Problems The general structure of a conventional card league is shown in FIGS. 1 and 2. The handle (3) is driven via the drive motor (a small pulley (2a) attached to the exit shaft) +4+. A coaxial Kmm feed roller 11 is attached to the feed roller (3). Further, the roller (3) is conveyor rollers (7) and (11).
is driven by belts (6) and (5). A pressing loaf (8) is provided in each conveyance loaf (++jl (yl) in order to ensure card conveyance by being biased toward each conveyance roller by a spring (not shown). The loaded card (1) is conveyed by the conveyance roller (7) and the pressing loaf (8), and is then transported to the next conveyance leaf (1).
Sent to α. This method has the drawback that the volume of the entire card league increases because the conveying leaf and the drive motor are configured separately. In contrast to the conventional card leagues as described above, a type of card league has also been proposed in which a card is fixed at a conveyance contact position and a sliding member having a card signal reading section or writing section is driven. Examples of the head moving type card league are shown in FIGS. 8 to 5. In the figure, the output shaft 123 of the drive motor ■
A worm gear (incorporated) is attached to 1, and the worm gear (for example, pinion gear (5)) is in contact with each other.
A support) and a punishment are attached, each transmitting rotation in the opposite direction. The one-way clutch (9A drives the belt pulley 3), and the belt transport is further driven. A card is inserted between the belt (support) and ■, and the card is transported. On the other hand, the sliding member having the reading part or writing part of the card signal is a one-way clutch, and the pair A/
The reading of signals from the card and the writing of signals to the card are carried out by a signal detecting head (driven through three wires). C1 is a belt. This method has disadvantages in that the space for the drive motor becomes large, the overall volume of the product becomes large, and the driving force transmission system is complicated, as in the conventional example shown in FIGS. 1 and 2.

OBJECTS OF THE INVENTION The present invention solves the above-mentioned conventional drawbacks, and aims to reduce the overall volume of the card league with a simple configuration.

Structure of the Invention In order to extract relatively large torque, a geared motor was developed in which the rotating shaft of the motor body is decelerated by a reduction gear train built in the same casing, and the output is output from an output shaft concentric with the rotating shaft of the motor. ing. Since the rotation speed of the output shaft of this geared motor is geared down and is not large, it is excellent in that there is no need to use a separate reduction gear train. In order to achieve the above object, the present invention makes it possible to downsize the card league main body and simplify the card transport mechanism by using the motor casing of such a geared motor as a card transport port. This card conveyor is designed with a focus on the ability of the drive motor to be rotated, with a cylindrical casing surrounding the drive motor that rotates around the output shaft of the drive motor, and a card being guided and conveyed by the rotation of the cylindrical casing. It has a mechanism.

DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of the present invention will be described based on the drawings. First, a first embodiment shown in FIGS. 6 and 7 will be described. In the figure, reference symbol ( ) is a drive geared motor, and this geared motor ring is wrapped with an elastic body (η) such as rubber or the like around the outside of its cylindrical casing so that the card can be transported more reliably. The output shaft (c) of the guard motor←l) is fixed to the card league main body with a fixing ring 144.

The other end shaft of the guard motor (40) is supported by a bearing (manufactured by Co., Ltd.) so that it can rotate on the card league body. (11 is a slip ring for supplying power to the guard motor (b), and the brush A stain source is supplied to 4'A. When a card is inserted from the insertion slot, a detection switch (not shown) detects the insertion of the card, and the casing of the geared motor (4η) starts rotating clockwise. .The card is pressed against the outer surface of the elastic body Ul by the loaf 4 biased by the pressing spring (insulator) and is transported reliably. - is the support part of the card. (Since 4η can also have the function of a transport leaf, the volume of the entire card league can also be reduced.

Next, an eighth embodiment shown in FIGS. 8 and 9 will be described. There is a spur gear and a cap on the geared output shaft.

The groan transports it to the right in the figure. (When the card slides on the card support part and is conveyed to the card stopper (67 m), a sensor (not shown) sends a card conveyance completion signal to the electric circuit section. After the card conveyance is completed, the solenoid I is turned on, the power transmission switching member (to) connected by the pin (@) rotates counterclockwise, the pawl (59b) enters the tooth (a2m) of the gear (@), and the At the same time that the rotation of the guarded motor casing is restrained, the claw portion (5oa) and the spur gear are disengaged, and the output shaft of the guarded motor 5η becomes rotatable. This state is shown in Fig. 9. Card Since the geared motor casing was rotated clockwise during transportation, the output shaft l[1g of the geared motor is rotated counterclockwise by switching the power transmission switching member l.

Due to the configuration of the power transmission system, the pulley (6@) also rotates in the same direction as the output axis, that is, counterclockwise, and the sliding member 15η drives the card-1 to the left in the figure. There is a pressure spring (5γ-), and a signal reading/writing head (57
b) is urged downward in the figure. When the sliding member is driven to the left in the figure, the signal read/write head (57b

The direction of rotation of the guard sweater is reversed. As a result, the sliding member is driven to the right in the figure. The sliding and moving member 15η reaches the right end, and the eighth
When the state shown in the figure is reached, the solenoid l is turned off, and the power transmission switching member rotates clockwise by the force of the spring el, and at the same time, the rotation of the output shaft 6η of the geared motor is restrained, and at the same time, the casing of the geared motor rotates counterclockwise. The card rotates, ejects the card, and completes the series of operations.

Effects of the Invention As described above, according to the present invention, the drive motor itself has the functions of the drive motor and conveyance roller in a conventional card conveyance mechanism, and the sliding member can read and write signals using the motor output. By driving the card reader, the power transmission system is simple, and the card reader can be made smaller, lighter, and more reliable.
