Abstract

PURPOSE:To easily and rapidly draw a memory card out of a card case by providing a card receptacle part having a slit-like opening through which cards are received and a supersonic motor for ejecting the received card through the opening. CONSTITUTION:A card cases (commutation ticket receptacle) is taken out of a pocket to allow an opening 12 of the card case to oppose to a commutation ticket inserting port of an automatic ticket examining machine. When a power source is then turned on by depressing a switch 16, high-frequency voltage is applied to a piezo-electric body 8 constituting a supersonic motor 2. The piezoelectric body 8 is excited by the application of the high-frequency voltage to excite bending vibrations on the surface of an elastic body 7 along with the excitation. The bending vibration progresses leftward on the surface of the elastic body 7. Under the condition of this movement, the commutation ticket 6 makes contact only with the wave head (the maximum point of longitudinal displacement) of the elastic body 7 to be transferred and ejected from the opening 12. The ejected commutation ticket is taken into the automatic ticket examining machine to be processed.

[0002]

2. Description of the Related Art In recent years, various memory cards as input / output means have become widespread with the development of small computer systems. These memory cards are called telephone cards, cash cards, credit cards, prepaid cards, customer cards, library use cards, etc., depending on the use and function. On the other hand, the memory card is also used as a commuter pass or a ticket in an automatic ticket gate system at a station. Nowadays, people carry various memory cards in their wallets, commuter pass cases, or special card cases. Then, various service departments have come to benefit from quick service by performing processing through a memory card.

[0003]

By the way, there is a situation in which the above-mentioned memory card, which is supposed to provide quickness of service, is a cause of annoyance. For example, under the conventional manned ticket system, it would have been good for passengers to show the clerk with the commuter pass stored in the commuter pass, but under the automatic ticket system described above, Before passing through the ticket gate, memory card (commuter pass)
Had to be removed from the commuter pass and inserted into the commuter pass slot of the automatic ticket gate, and after passing through the ticket gate, the memory from the commuter pass outlet of the automatic ticket gate I had to take out the card (commuter pass) and store it again in the commuter pass. To insert and remove the memory card (commuter pass) from the commuter pass, it has not been necessary to do such a task in the past,
It makes people feel more complicated. It is extremely difficult to insert and remove a memory card (commuter pass) while carrying heavy luggage in both hands.

For a left-handed person, the operation of inserting a memory card (commuter pass) into the commuter pass insertion slot of an automatic ticket gate is not an easy operation. Since the commuter pass insertion slot of the automatic ticket gate system is generally provided on the right side of the gate,
This is because left-handed passengers must bend their bodies, extend their left hands to the right, and insert a memory card (commuter pass). Such complexity is not limited to the commuter pass. For example, from a commuter pass that is full of banknotes and business cards, select the desired memory card (for example,
It is often experienced that it takes a lot of time to remove the telephone card). The present invention has been made in view of the above circumstances, and provides a card case capable of automatically and swiftly inserting and removing the card. It is an object.

[0005]

In order to solve the above-mentioned problems, the present invention according to claim 1 has a slit-shaped entrance and exit for storing a card, and a card storage portion for storing the card. It is characterized by comprising an ultrasonic motor for ejecting the card from the entrance.

Further, the invention according to claim 2 is provided with a card storage portion having a slit-shaped entrance for accommodating a card, and an ultrasonic motor capable of discharging and accommodating the card via the entrance. It is characterized by

Further, the invention according to claim 3 is characterized by comprising a plurality of the card storage portions and a plurality of the ultrasonic motors corresponding to the respective card storage portions.

According to a fourth aspect of the present invention, there is provided a card storage portion having a slit-shaped entrance and exit for accommodating a card, a first ultrasonic motor for ejecting the card through the entrance and exit, and the entrance and exit. And a second ultrasonic motor for storing the card.

According to a fifth aspect of the present invention, there is provided a plurality of the card storage sections and a plurality of the first and second ultrasonic motors corresponding to the respective card storage sections. I am trying.

Further, the invention according to claim 6 is characterized by comprising a photo sensor switch for driving the corresponding ultrasonic motor to eject the card when it is sensed by light.

Furthermore, the invention according to claim 7 is characterized in that the portable card case accommodates a commuter pass consisting of a magnetic card, a telephone card, a cash card, a credit card and the like.

[0012]

According to the above construction, it is unnecessary to take out the memory card (commuter pass) from the commuter pass case and insert it into the commuter pass insertion slot of the automatic ticket gate. Therefore, it is possible to easily and quickly pass through the ticket gate even while carrying heavy luggage in both hands. This also avoids confusion in the station yard during rush hours. Also,
Even under the current situation where the commuter pass insertion slot of the automatic ticket gate is provided on the right side, the disadvantage of the left-handed person is remarkably alleviated. Generally, it is possible to easily and quickly remove the memory card from the card case.

Embodiments of the present invention will be described below with reference to the drawings. (First Embodiment) FIG. 1 is a schematic sectional view showing the mechanical structure of a card case according to the first embodiment of the present invention. As shown in the figure, this card case is roughly composed of a substrate 1, an ultrasonic motor 2, a card storage unit 3, a power supply unit 4, and an upper plate 5.

The substrate 1 is a rectangular plate body made of, for example, plastic, metal, ceramics or the like, and its suitable dimensions are a length of 7 to 15 cm and a width of 4 to 10 cm. is there.

The ultrasonic motor 2 is a power unit for ejecting and driving a card (memory card or the like) 6, and is roughly composed of a plate-shaped elastic body 7, a piezoelectric body 8 and a vibration absorber 9. For the elastic body 7, for example, a stainless plate or an aluminum plate is used. The piezoelectric body 8 is firmly adhered to the right end of the lower surface of the elastic body 7, while the vibration absorber 9 is adhered to the left end of the lower surface. 2 is a sectional view taken along the line AA of FIG. 1, and as shown in this figure, the elastic body 7
Via the wings 10, 10 provided on both sides of the
It is attached and fixed to the side plates 11 of the card case.
The side plates 11 and 11 are formed of, for example, metal or hard plastic.

The piezoelectric body 8 is formed of a rectangular piezoelectric ceramics plate that has been subjected to a desired polarization treatment, and electrodes (not shown) are formed on both surfaces thereof. Further, the vibration absorber 9 absorbs the flexural vibration of the elastic body 7, and is preferably made of a highly elastic member or a soft member, and may be composed of a piezoelectric body.

The upper plate 5 is made of a transparent plate such as plastic or hard glass so that the card 6 can be seen from the outside. The preferred dimensions of the upper plate 5 are the same as those of the substrate 1.

The card storage section 3 includes an elastic body 7 and an upper plate 5.
And a gap about the thickness of the card 6 (slit-like gap)
And is arranged opposite to each other, so that a space for storing the card 6 is secured. The space is adjusted so that the back surface or the front surface of the card 6 is pressed against the elastic body 7 when the card 6 is stored in the card storage portion 3.

At the right end of the card storage portion 3, an opening portion 12 for inserting and discharging the card 6 is formed. The opening 12 is formed so that the outermost part is widest and the inner part is gradually narrowed so that the card 6 can be easily inserted.

The power supply unit 4 is an electric circuit for supplying driving power (high frequency voltage) to the ultrasonic motor 2, and is shown in FIG.
As shown in FIG. 3, the battery 13 is composed of a single battery or a plurality of small batteries, an ultrasonic oscillator 14, and a voltage amplifier 15. The power supply unit 4 is mainly integrated at the rear end of the card case (left side in FIG. 1).

The ultrasonic oscillator 14 outputs a high frequency voltage which oscillates at a frequency in the ultrasonic range, and the outputted high frequency voltage is applied to both electrodes of the piezoelectric body 8 via the amplifier 15. There is. Here, as will be described later, the frequency of the high-frequency voltage is the wavelength of the bending vibration generated on the surface of the elastic body 7 due to the application of the high-frequency voltage,
It is set to be sufficiently smaller than the length of.

The power supply from the power supply unit 4 to the ultrasonic motor 2 is turned on / off by the switch 16. The switch 16 is attached to a recess (not shown) of the upper plate 5, and the recess is covered with a flexible rubber film (not shown). Each time the switch is pressed down through the flexible rubber film, the switch is turned on and off repeatedly.

As the card case having the above structure, a pocket size is suitable, but a handbag size or a bag size is also suitable. On the contrary, it may be smaller than the pocket size. In short, any size may be used as long as it is portable according to common sense. Specifically, the card case of this example preferably has a thickness range of 0.3 to 3 cm, a length of 7 to 15 cm, and a width of 4 to 10 cm.

Next, the operation when the card case having the above-mentioned structure is used as a commuter pass will be described. When approaching the automatic ticket gate at the station, the passenger walks and puts his card case (commuter pass) in his pocket of clothes.
The card case is taken out and carried to the automatic ticket gate, and the commuter pass insertion slot of the automatic ticket gate and the opening 12 of the card case face each other, and at the same time, the switch 16 is pressed with a finger to turn on the power.

When the power is turned on, a high frequency voltage is applied to the piezoelectric body 8 forming the ultrasonic motor 2. The piezoelectric body 8 is excited by the application of the high-frequency voltage, and the bending vibration is excited on the surface of the elastic body 7 in accordance with the excitation. This bending vibration propagates (propagates) to the left side of the figure on the surface of the elastic body 7. The traveling wave of bending vibration (hereinafter referred to as bending traveling wave) is
When it reaches the left end of the elastic body 7, it is received by the vibration absorber 9. During the generation of the bending traveling wave, each mass point on the surface of the elastic body 7 moves along an elliptical orbit, and the mass point of the wave front moves in the direction opposite to the phase velocity of the bending traveling wave.

As described above, the wavelength of the bending traveling wave is set to be sufficiently shorter than the length of the commuter pass (card 6). Therefore, in this exercise state, the commuter pass has a wave front (longitudinal). The maximum point of directional displacement). Therefore, the commuter pass is conveyed in the direction opposite to the phase direction of the bending traveling wave and is discharged from the opening 12. The discharged commuter pass is taken into an automatic ticket gate and processed. In this case, after the commuter ticket has been discharged to some extent, it is possible to proceed with the commuter ticket discharge from the card case and the commuter ticket take-in of the automatic ticket gate at the same time.

According to the above construction, it is not necessary to take out the commuter pass from the commuter pass case and insert it into the commuter pass insertion slot of the automatic ticket gate. Therefore, even when carrying heavy luggage in both hands, it is possible to easily and quickly pass through the ticket gate. Further, even under the current situation where the commuter pass insertion slot of the automatic ticket gate is provided on the right side, the disadvantage and inconvenience of a left-handed person is remarkably alleviated.

At the manned ticket gate station, it is not necessary to take out the commuter pass, and it is sufficient to show the card case to the staff. The clerk can see the contents of the commuter pass through the upper board as in the case of the conventional commuter pass.

Further, in the above embodiment, the elastic body 7
The greater the contact friction between the card 6 and the card 6, the easier the card 6 is to be ejected. Therefore, as the material of the elastic body 7,
It is preferable that the card 6 has a large frictional force. Alternatively, the same effect as described above can be obtained by coating the surface of the card 6 with a material having a large frictional force with respect to the elastic body 7.

In addition to the above structure, a crimping member (for example, a spring plate or the like) for strongly crimping the elastic body 7 and the card 6 together.
Even with the above, a large frictional force can be obtained in the same manner as above. In this case, when the power supply to the ultrasonic motor is turned on, the pressure contact member may be activated to press the card and the elastic body against each other.

On the other hand, the smaller the contact friction between the upper plate 5 and the card 6, the easier the card 6 is to be ejected. Therefore,
As a material for the upper plate 5, a material having a small frictional force with respect to the card 6 is suitable. Alternatively, the same effect as described above can be obtained by coating the inner surface of the upper plate 5 with a material having a small frictional force. If a minute roller-shaped body is provided between the card 6 and the upper plate 5, the card 6
Can be discharged more smoothly.

Further, in the above-mentioned embodiment, the case where the power source is alternately turned on and off every time the switch 16 is pressed is described, but in addition to this, the card 6
When the switch 16 is not stored, the switch 16 may not be turned on even if the switch 16 is pressed.
In addition, when the card is ejected to a predetermined position, the power may be automatically turned off. Card 6
It is possible to determine whether or not is stored by adding a photo sensor.

In the above embodiment, the flexible switch 16 is used, but the switch 16 is accidentally pressed in a pocket or the like,
In order to prevent accidents such as ejection of the card 6, a lock switch having a strong holding force and safety may be separately provided. Then, the ultrasonic motor 2 may be operated only when both the lock switch and the switch 16 are turned on.

Further, in the above-mentioned embodiment, the case where the flexible switch 16 which is actuated by pressing is used has been described, but instead of or in addition to this, daytime light, fluorescent lights in the station yard, etc. A photosensor switch that is turned on when it is sensed by the light may be provided between the power supply unit 4 and the ultrasonic motor 2. If you do this, you can simply remove the card case from your pocket,
The ultrasonic motor operates and the card is automatically ejected, which is extremely convenient. Flexible switch 16
Instead of the above, in the configuration using the photo sensor switch, a stop switch for stopping the drive of the ultrasonic motor may be added separately. Also in the following embodiments, if the photosensor switch is used,
The same effect as described above can be obtained.

In the above embodiment, the power supply unit 4
Although the description has been given of the case where it is provided mainly at the rear end portion (FIG. 1) of the card case, it is needless to say that it is not limited to the rear end portion.

Further, in the above-mentioned embodiments, the case where the voltage is obtained by the battery 13 composed of one or a plurality of small batteries has been described. However, when a relatively high voltage is required, a booster device is appropriately used. You may do it. In addition, a rechargeable battery may be used. Further, the battery 13 may be configured to include a solar cell.

Further, in the above-mentioned embodiment, the case where the single piezoelectric body 8 is used has been described, but the present invention is not limited to this, and a plurality of piezoelectric bodies may be used.

Further, in the above embodiment, the card 6
Although the case where the card 6 is constituted by the elastic body 7 having substantially the same size as that of the card 6 has been described (FIG. 1), the above is an example. A plurality of elastic bodies may be used.

Further, in the above-mentioned embodiment, the case where the vibration absorber 9 is inserted between the substrate 1 and the elastic body 7 has been described, but the present invention is not limited to this, and the elastic body 7 and the upper plate 5 are combined. You may make it interpose.

In the above embodiment, the ultrasonic motor is composed of the elastic body 7, the piezoelectric body 8 and the vibration absorber 9, but the card 6 itself can be the vibration absorber. In this case, the vibration absorber 9 can be omitted.

Further, in the above embodiment, the piezoelectric body 8
Although the case of using the traveling wave type ultrasonic motor by the combination of and the vibration absorber 9 has been described, other traveling wave type ultrasonic motors may be used, and commercially available ultrasonic motors other than the above may be used. Is also good.

(Second Embodiment) FIG. 4 is a sectional view showing the structure of a card case according to the second embodiment of the present invention. The card case of this example is largely different from that of the first embodiment in place of the traveling wave type ultrasonic motor 2 (FIG. 1).
The point is that a standing wave type ultrasonic motor 17 is provided. The ultrasonic motor 17 of this example, as shown in FIG.
The piezoelectric body 18 and an elastic body 20 having sawtooth-shaped projections 19, 19, 19 on the surface are roughly configured. The protrusions 19, 19, 19 are arranged at predetermined positions on the elastic body 20 (positions shown in FIG. 5B described later), contact the card 6 to transmit driving force, and eject the card 6. It is supposed to do. Spacers 21, 21 are provided on the left and right sides of the ultrasonic motor 17 in the figure. These spacers 21,
A rubber member 21 is used so as not to affect the vibration mode of the ultrasonic motor 17. In FIG. 4, the same components as those of the card case (FIG. 1) of the first embodiment are designated by the same reference numerals and the description thereof will be omitted.

Next, the driving principle of the standing wave type ultrasonic motor 17 will be described. The ultrasonic motor 17 of this example is
Since the elastic body 20 does not have the vibration absorber 9, the vibration mode of the elastic body 20 is a standing wave (hereinafter referred to as a bending standing wave) due to a bending wave, as shown in FIG. By the excitation of the bending standing wave, each mass point on the surface of the elastic body undergoes displacement vibration in the vertical direction except for a portion corresponding to a node. In this state, each mass point moves in the direction toward the node as indicated by the arrow in FIG. 4A when it is displaced in the direction of increasing thickness. Therefore, as shown in (c) of the figure, the protrusions 19, 19, and only on the mass point that moves to the right in the figure.
By forming 19, the driving force for conveying (discharging) the card 6 to the right can be obtained.

As shown in FIG. 7B, if the projections 19, 19, 19 are formed only on the mass point that moves to the left in the figure, the drive for conveying the card 6 to the left. You can get power.

According to the above construction, the same effect as described above in the first embodiment can be obtained.

In the above embodiment, the piezoelectric body 1
8 and the case where the standing wave type ultrasonic motor composed of the elastic body having the three projections 19, 19, 19 is used, the number of the projections is not limited to three. Alternatively, it may have a single protrusion. Further, it is also possible to configure by using a woodpecking type standing wave type ultrasonic motor, and a commercially available standing wave type ultrasonic motor other than the above may be used.

(Third Embodiment) FIG. 6 is a sectional view showing the structure of a card case according to the third embodiment of the present invention. The card case of this example is greatly different from the first and second embodiments in that it has a function of automatically storing a card in addition to a function of automatically storing the card.

In order to have the above-mentioned automatic discharging / storing function, an ultrasonic motor capable of reversing drive is used in this example.

As shown in the figure, the ultrasonic motor 24 of this example is roughly composed of a plate-shaped elastic body 7 and two piezoelectric bodies 8a and 8b. These piezoelectric bodies 8a, 8b
Are adhered and fixed near the left end and the right end of the lower surface of the elastic body 7, respectively.

The piezoelectric body 8a is arranged to convey (discharge drive) the card 6 rightward in the drawing, and the piezoelectric body 8b is also provided.
Are arranged to convey (store and drive) the card 6 leftward in the drawing. Switching of the transport direction, that is, switching of card ejection / storing is performed by the key switches 25a and 25b attached to the upper plate 5.

The key switch 25a is a switch for ejecting a card. When the key switch 25a is pressed, the piezoelectric body 8a is powered on, and when it is pressed again, the power is cut off. The key switch 25b is a switch for storing a card. When the key switch 25b is pressed, the piezoelectric body 8b is powered on, and when it is pressed again, the power is cut off.

When power is applied to one of the piezoelectric bodies to form an exciting circuit, the other piezoelectric body or the like forms a wave receiving (vibrating) circuit. Also,
Since the ultrasonic motor 24 can be driven in reverse, it is not necessary to separately provide a discharge port and a storage port. Therefore, the opening 12
However, the opening 17 is not provided as in the second embodiment.

In the configuration of the third embodiment, the card 6
When discharging, the key switch 25a is pressed. When the key switch 25a is pressed, a high frequency voltage is applied to both electrodes of the piezoelectric body 8a. At this time, since the piezoelectric body 8b is set to the wave receiving mode, an elastic traveling wave whose phase propagates leftward in the drawing is generated on the surface of the elastic body 7. Since the mass point of the wave front of the elastic traveling wave moves in the direction opposite to the propagation direction of the traveling wave as described above, the card 6 is conveyed to the right in the figure and ejected from the opening 12.

Next, when storing the card, the key switch 25b is pressed. When the key switch 25b is pressed, a high frequency voltage is applied to both electrodes of the piezoelectric body 8b. At this time, since the piezoelectric body 8a is set to the wave receiving mode, an elastic traveling wave whose phase propagates rightward in the drawing is generated on the surface of the elastic body 7. Therefore, the card 6 is conveyed to the left in the drawing via the opening 12 and stored.

According to the configuration of the third embodiment, the card 6
The automatic ejection / storage of can be done via only a single opening. Therefore, it is possible to avoid the trouble of holding the card case 180 degrees between when it is discharged and when it is stored.

It should be noted that, in the drawing, the arrangement and the number of piezoelectric bodies on the elastic body are shown schematically, and are not limited to the illustrated examples.

Further, in the above-mentioned embodiment, the case where the key switch 25b is used as the card storing switch has been described, but instead of or in addition to this, a photo sensor or a pressure sensor is provided in the card storing section. It may be configured such that it is attached to the opening portion or in the vicinity thereof and the piezoelectric body 8b is powered on when these sensors detect the entry of the card. By doing so, the ultrasonic motor is activated by inserting the card into the opening a little and the card is automatically stored, which is extremely convenient. This also applies to the following examples.

(Fourth Embodiment) FIG. 7 is a plan sectional view showing the structure of a card case according to a fourth embodiment of the present invention. Similar to the third embodiment, the card case of this example also has an automatic card ejection / storing function. However, instead of the reversible traveling wave type ultrasonic motor (FIG. 1), the directions are opposite to each other. The third embodiment is different from the third embodiment in that two standing wave type ultrasonic motors 17a and 17b for generating the driving force are provided.

The ultrasonic motors 17a and 17b are arranged in parallel to each other in the left-right direction, and the piezoelectric bodies 18a and 1b are respectively arranged.

a is formed.

The ultrasonic motor 17b is a motor for storing the card 6, and the elastic body 20b has
Protrusions 19b, 19b, 19b are formed at the positions shown in FIG. 5 (b). Since the drive direction is determined by the arrangement position of the protrusion as described above in the second embodiment, the description thereof will be omitted. Note that, in FIG. 7, attaching members, spacers, and the like of the ultrasonic motors 17a and 17b are omitted for simplicity.

According to the above construction, the same effect as described above in the third embodiment can be obtained.

In the fourth embodiment described above, the case where two standing wave type ultrasonic motors 17a and 17b are arranged in parallel in the left-right direction has been described, but the present invention is not limited to this, and the front-back direction is not limited to this. You may make it arrange | position in parallel.

Further, in the above-mentioned fourth embodiment, the case where two standing wave type ultrasonic motors 17a, 17b for generating driving forces in mutually opposite directions are arranged on the same plane has been described. However, the present invention is not limited to this, and the ultrasonic motors 17a and 17b may be arranged to face each other with the card 6 interposed therebetween.

Further, in the above-mentioned fourth embodiment, the case where a pair of standing wave type ultrasonic motors 17a, 17b which generate driving forces in mutually opposite directions is used has been described, but the present invention is not limited to this. Instead, two or more pairs of ultrasonic motors may be appropriately used.

Further, in the above-mentioned fourth embodiment, the case where the elastic body and the projection are integrally formed has been described.
The elastic body and the protrusion may be formed separately. In this case, the protrusion is made relatively movable along the surface of the elastic body, and the changeover switch is used to properly move the

(Fifth Embodiment) FIG. 8 is a sectional view showing the structure of a card case according to the fifth embodiment of the present invention. The major difference between the card case of this example and the first embodiment described above is that the card case of this example is configured to accommodate a plurality of (two) cards.

As shown in the figure, the card case of this example includes a substrate 26 and a first substrate arranged on both sides of the substrate 26.
And second ultrasonic motors 27a and 27b, first and second card storages 28a and 28b adjacent to the ultrasonic motors 27a and 27b, and the card storage 2

The first and second ultrasonic motors 27a,
27b is composed of plate-shaped elastic bodies 31a and 31b, piezoelectric bodies 32a and 32b, and vibration absorbers 33a and 33b, respectively. The piezoelectric body 32a and the vibration absorber 33a
Is interposed between the upper surface of the substrate 26 and the elastic body 31a. The piezoelectric body 32b and the vibration absorber 33b are inserted between the lower surface of the substrate 26 and the elastic body 31b.

Since the above-mentioned constituent elements of this example are the same as the corresponding constituent elements of the first embodiment, the description thereof will be omitted. Also, the vibration absorbers 33a and 33b can be omitted as appropriate, as in the first embodiment.

The upper plates 29a, 29b have switches 34a, 3 for driving the ultrasonic motors 27a, 27b.

When the switch 34a is pressed down, the power supply unit 30 and the first ultrasonic motor 27a are electrically connected, and when the switch 34a is pressed down again, the power is cut off electrically, while the switch 34b is opened. When the button is pressed, the power supply unit 30 and the second ultrasonic motor 27b are electrically connected, and the switch 34 is turned on again.
When b is pressed, it is electrically cut off.

In the above structure, for example, at the automatic ticket gate of a station, when the key switch 34a is pressed, the commuter pass 35a in the card storage 28a is automatically discharged through the opening 36a, and in the public telephone box, When the key switch 34b is pressed, the telephone card 35b in the card storage 28b is automatically ejected through the opening 36b. Thus, according to the configuration of the fourth embodiment, it is possible to automatically store a plurality of cards.

In the fifth embodiment described above, the case where two card storages are provided has been described, but the present invention is not limited to this. For example, if five card storages are provided, commuter tickets, telephone cards, cash cards, credit cards, and customer cards can be stored together in a single card case.

Further, in the above-mentioned fifth embodiment, the case where the two card accommodating portions are laminated and fixed has been described, but instead of this, they may be formed so as to be a laminated spread.

In the above fifth embodiment, the first
Although the case where the configurations of the embodiments are stacked is described, the present invention is not limited to this case, and the configurations of the second to fourth embodiments may be stacked, and the first embodiment is also possible. Alternatively, a laminated structure formed by hybridizing the fourth embodiment may be used.

Further, in the above-described embodiment (the first to fifth embodiments, the same applies below), the case where all of the plurality of card storage units are provided with the automatic ejection function has been described, but the present invention is not limited to this. However, one card storage unit may not have the automatic ejection function.
For example, it may be a card case in which a conventional business card holder or bill holder that cannot be automatically discharged is added to a card storage unit having an automatic discharging function. In this case, the conventional business card holder and bill holder may be made of leather. Further, in the above-mentioned embodiment, the case where the memory card is stored is described, but the present invention is not limited to this, and a normal card such as a medical examination card may be used. It can also be stored.

Further, in the above-mentioned embodiment, the case where one card is stored in one card storage section has been described, but a plurality of cards can be stored simultaneously. In the case where a plurality of cards are stored at the same time, a card can be sequentially ejected by providing a crimping mechanism that constantly crimps the remaining cards to the elastic body at the same time.

The above memory card is not limited to a magnetic card, but may be an optical card or an IC card.

It is also possible to add a timepiece mechanism to the card case having the above structure. It may be a so-called card case with a clock. Similarly, a card case with a calculator,
It may be a card case with a radio, a card case with a tape recorder, a card case with an electronic notebook, a card case with a system notebook, a card case with a key holder, a card case with a ballpoint pen or a mechanical pencil. Further, it is conceivable to combine the card case with a portable cosmetic case for storing a mirror, a comb, lipstick, perfume and the like. Furthermore, a combination of a suitcase and a card case, a portable personal computer (or word processor) and a card case, and a mobile phone (or pager) and a card case are possible. In this way, by integrating the individual products, it is possible to provide consumers with a deeper sense of satisfaction and novelty, thereby increasing demand. The combination of two products is not limited, and a combination of three or more products, for example, a card case including a clock mechanism and a calculation mechanism may be used.

Further, in the above-mentioned embodiment, the case where, for example, a piezoelectric ceramic is used as the piezoelectric body is described, but the present invention is not limited to this, and other piezoelectric bodies can be used. For example, if a polymeric piezoelectric material is used, the card case can be made even thinner, and the number of card storage portions can be increased more easily. Further, it is possible to realize a flexible card case.

If a transparent piezoelectric body and a transparent elastic body are used, it will be much easier to view the card from the outside.

Further, in the above embodiment, the case where the upper plate and the substrate have substantially the same length dimension has been described, but instead of this, the length dimension of the upper plate is smaller than that of the substrate. You can make it shorter. In this way, in addition to the automatic card ejection function, it is easy to eject the card with a finger.
In order to make it easier to store and discharge the card with your fingers,
For example, as shown in FIG. 9, the upper plate 40 may be formed in a plane convex shape.

Further, in the above-mentioned embodiment, the case where the upper part of the opening is constituted by the upper plate has been described, but the present invention is not limited to this, and it is formed by a soft (flexible) synthetic resin film or sheet. You may do it. By doing so, it becomes easier to store the card.

Further, in the above-mentioned embodiment, the case where the card case is composed of the substrate, the upper plate and the elastic body has been described. However, the elastic body may also serve as the substrate. You may make it serve as a board.

Further, in the above-mentioned embodiments, the case of using the traveling wave type or standing wave type ultrasonic motor has been described, but the present invention is not limited to these, and other types of ultrasonic motors may be used. However, the same effect as described above can be obtained.

Further, in the above embodiment, the case where the ultrasonic motor is used only on one side of the card has been described, but the present invention is not limited to this, and the same kind of ultrasonic motor may be provided on both sides of the card. However, in this way, since the driving force in the same direction is applied to both surfaces of the card, a stronger driving force can be obtained.

In the above embodiment, the case where the card itself slides on the surface of the elastic body in association with the driving of the ultrasonic motor has been described, but instead of this, the surface of the elastic body slides. A slide table may be provided, and a card may be placed on this slide table to be ejected / stored. Alternatively, the card may be moved via a motion extractor such as a small roller or a protrusion.

Further, in the above-mentioned embodiments, the case where the single-phase power source is used has been described, but a two-phase power source may be appropriately used. If a two-phase power source is used, it is easy to generate a traveling wave and reverse.

Further, as a modification of the above-mentioned embodiment, a discharge amount adjusting mechanism for presetting the discharge amount of the card may be provided. Similarly, a discharging / accommodating speed adjusting mechanism for arbitrarily adjusting the discharging / accommodating speed of the card may be provided.

As another modification of the above-mentioned embodiment,
By covering the magnetic card with a protective plate for protecting the magnetic card, the reliability of storage of the magnetic card can be further improved. In this case, the upper plate and the substrate may be made of a material having a magnetic card protection function.

As described above, according to the configuration of the present invention, it is troublesome to remove the memory card (commuter pass) from the commuter pass case and insert it into the commuter pass insertion slot of the automatic ticket gate. It becomes unnecessary. Therefore, it is possible to easily and quickly pass through the ticket gate even while carrying heavy luggage in both hands. This also avoids confusion in the station yard during rush hours.

Further, even under the current situation where the commuter pass insertion slot of the automatic ticket gate is provided on the right side, the inconvenience of a left-handed person is remarkably alleviated. Generally, it is possible to easily and quickly remove the memory card from the card case.
