Description

  The present invention relates to a light emitting clip for sandwiching an object.

  There is a clip as one of simple tools mainly for stacking a plurality of papers and fixing relatively small articles. In recent years, various types of clips have been marketed and distributed, and one of them is formed by bending a thin metal plate and using its elasticity to provide a clamping force (for example, Patent Document 1).

Utility Model Registration No. 3119064

  However, the relatively small number of documents, etc. are so thin that if they are sandwiched between clips as described above and stored between large books or file binders, the whole will not stand out. Often difficult to find later. Even if the clip itself is metallic and glossy, it is still difficult to find when there is no light and the surroundings are dark.

  An object of the present invention is to provide a light emitting clip capable of easily and reliably finding a document or the like and improving convenience.

  In order to achieve the above object, the first invention includes a clip body including a sandwiching part that sandwiches an object at open both ends that can be opened and closed, and a gripping part that can be gripped by a finger, and the sandwiching part includes: The light-emitting unit is configured to emit light in a direction substantially opposite to the direction in which the light can be opened and closed, and a power supply unit that is electrically connected to the light-emitting unit and supplies power to the light-emitting unit.

  The light emitting clip of the first invention of the present application includes a clip body. The clip main body includes a sandwiching portion and a gripping portion as in the case of a general clip. An object is sandwiched between open ends of the clamping unit that can be opened and closed. The grip portion can be gripped by a finger.

  And in this-application 1st invention, the light emission part is provided on the opposite side to the side which pinches | interposes the target object of the said clamping part so that it may light-emit in the direction substantially opposite to the direction which can be opened and closed. Power is supplied to the light emitting unit for light emission from the power supply unit. Thus, even when the operator inserts an object such as a document or file into the holding unit and then stores the document on a shelf or the like, the light emitting unit emits light on the side opposite to the holding side, On the other hand, visual notification can be performed. Thereby, the operator can find the document etc. easily and reliably, and the convenience is improved.

  In a second aspect based on the first aspect, the clamping part is formed of an elastic plate having a U-shaped cross section, and the gripping part is rotatably supported at both open ends of the clamping part. The light emitting part is provided at least on the U-shaped bottom part of the clamping part.

  In the second invention of the present application, the sandwiching portion is constituted by an elastic plate having a U-shaped cross section. When the object is sandwiched, the open ends of the clamping unit are opened by the force from the gripping unit that is rotatably supported.

  And even after the operator inserts an object such as a document or a file into the U-shaped interior from the open ends of the clamping unit opened as described above, the light emitting unit is formed at the U-shaped bottom of the clamping unit. By emitting light, it is possible to reliably perform visual notification to the operator.

  According to a third invention, in the first or second invention, according to the detection result of the switch means provided at the open both ends of the holding portion, and detecting whether or not the object is pinched, And control means for controlling power feeding to the light emitting part by the power feeding part.

  Accordingly, the light emitting unit does not emit light until the clip is used by the operator, and the light emitting unit emits light when the operator inserts the object into the holding unit and starts using the clip. Thereby, useless power consumption before use can be prevented.

  According to a fourth aspect of the present invention, in the third aspect of the present invention, the wireless tag circuit unit is provided in the clamping unit or the grip unit, and the control unit operates the wireless tag circuit unit according to a detection result of the switch unit. The power feeding unit feeds power to the light emitting unit and the RFID tag circuit unit.

  Thus, until the clip is used by the operator, the wireless tag circuit unit does not operate and the light emitting unit does not emit light. When the operator inserts the object into the holding unit and starts using the clip, the RFID circuit unit is activated and the light emitting unit can emit light. Thereby, useless power consumption before use can be more reliably prevented. Further, since the RFID circuit unit does not operate when the clip is not used, it is possible to prevent the RFID tag of the unused clip from malfunctioning and responding.

  A fifth invention is the above-mentioned fourth invention, wherein the switch means is two electrode means respectively provided at both open ends of the clamping part, and the state in which the object is not sandwiched is set between the two electrode means. While detecting as a short circuit, the state which pinched | interposed the said target object is detected as opening of the said two electrode means, It is characterized by the above-mentioned.

  In the fifth invention of the present application, the two electrodes are in contact with each other until the operator grips the grip portion in order to use the clip, and the switch means detects the non-holding state of the object by the short circuit state. When the operator grips the grip portion when using the clip and the force acts on both open ends of the gripping portion to separate the two electrodes, the switch means holds the object in the open state. The state can be detected.

  According to a sixth aspect of the present invention, in the fourth or fifth aspect of the invention, the RFID circuit unit includes an IC circuit unit and a tag antenna that is electrically connected to the IC circuit unit and transmits / receives information. The circuit unit includes a storage unit that stores information, a demodulation unit that demodulates information received by the tag antenna, a modulation unit that modulates information to be transmitted from the tag antenna, the storage unit, and the demodulation unit And the power supply unit for supplying power to the light emitting unit and supplying power to the entire IC circuit unit including the modulation unit, and the power supply unit of the IC circuit unit is received by the tag antenna. The stored radio wave energy is stored, and drive power is supplied to the entire IC circuit unit including the storage unit, the demodulation unit, and the modulation unit.

  As a result, even if the wireless tag circuit unit does not have a self-power source, the light emitting unit can be fed using the energy of the received radio waves to emit light.

  According to the present invention, documents and the like can be found easily and reliably, and convenience can be improved.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  1 to 3, the light emitting clip 100 according to the present embodiment includes a main body holding unit 1 as a holding unit that holds an object P such as a document or a clear file, and a holding unit that an operator can hold with a finger. As two antenna grips 2, 2, two inner covers 3, 4, a light emitting unit 6, and an IC circuit unit 7.

  The main body clamping unit 1 is constituted by an elastic plate obtained by bending a single elastically deformable metal thin plate, and its cross-sectional shape is generally U-shaped (see FIG. 2A) at normal times. . The base portions of the antenna grips 2 and 2 are rotatably attached to the roll portions 1b located at both ends of the elastic plate of the main body holding portion 1, and the operator grips the antenna grips 2 and 2, The said roll part 1b can be opened and closed elastically. At the time of use, as shown in FIG. 3A, the roll part 1b is opened to open the opening part 1a, and the object is sandwiched in the opening part 1a. Cutouts 1c are formed at two locations on the center side from the roll portion 1b.

  The antenna grip 2 is formed by bending a single metal wire, for example. Both end portions of the antenna grip 2 are bent at substantially right angles at two cutout positions of the roll portion 1b of the main body holding portion 1 and inserted into the roll portion 1b, and other exposed portions are rolls. It is formed in a semi-annular shape that opens toward the portion 1b. Since both end portions of the antenna grip 2 inserted in the roll portion 1b are arranged in a straight line, the entire antenna grip 2 can be rotated around these both end portions.

  When the two antenna grips 2 and 2 are respectively in the rotation positions adjacent to the substantially U-shaped side portions of the main body holding portion 1 (see FIGS. 2A and 2B), By sandwiching the two antenna grips 2 and 2 with fingers so as to be close to each other, the main body clamping unit 1 opens the opening 1a (see FIGS. 3A and 3B). The main body clamping unit 1 can clamp the object P by the opening 1a. In the present embodiment, as will be described later, these two antenna grips 2 are also electrically connected to the IC circuit unit 7 and function as a tag antenna for wireless communication (see FIG. 4 described later). The two antenna grips 2 and the main body clamping portion 1 constitute a clip main body according to each claim.

  The two inner covers 3 and 4 are thin plates each made of an insulating material, and are fixed to the inner sides of the U-shaped side of the main body holding portion 1. The IC circuit unit 7 is provided inside one inner cover 3. Further, the edges of the two inner covers 3 and 4 are in contact with each other on the side of the U-shaped opening 1a of the main body clamping unit 1. The edge portions of the inner covers 3 and 4 are provided with a first switch portion SW as a switch means for detecting the object sandwiched by the holding portion 1 using the contact of the edge portions.

  The first switch section SW1 has two contact terminals 5a and 5b as one electrode means and one connection bar 5c as the other electrode means. The two contact terminals 5a and 5b are provided side by side on the edge on the inner cover 3 (see FIGS. 2B and 3B). These two contact terminals 5a and 5b are connected to the IC circuit unit 7 in such a manner that they are spaced apart from each other so that they can be kept insulated from each other. The connection bar 5 c is provided at the edge on the inner cover 4. The connection bar 5c is arranged so that the two contact terminals 5a and 5b are electrically short-circuited in a normal state in which the open portion 1a is closed (see FIG. 2B). When the opening 1a is opened and the object P, which is an insulator like a document, is clamped by the main body clamping unit 1 in the use state shown in FIGS. 3A and 3B, two contact terminals are provided. 5a and 5b are separated from the connection bar 5c, and the electrical short circuit is opened.

  In this example, the light emitting portion 6 is formed in a rectangular shape, and as shown in FIG. 1B, FIG. 2A, and the like, an open portion 1a is formed at the bottom of the main body holding portion 1 in a substantially U shape. It is arranged to emit light toward the opposite side. In addition, you may provide in addition to places other than a bottom part among the clamping parts 1, and may provide a light emission part. For example, a known organic electroluminescence light emitting element (hereinafter referred to as an organic EL element) can be used for the light emitting unit 6. Although not shown in detail, the organic EL element includes a light emitting layer, a cathode layer provided on one side of the light emitting layer, and an anode layer provided on the other side of the light emitting layer.

  The light emitting layer is a layer containing organic EL, and emits light when a voltage is applied between the cathode layer and the anode layer. Examples of the organic EL include polymer light emitting materials such as polyparaphenylene vinylene derivatives, polyfluorene derivatives, polythiophene derivatives, tetraphenylbutadiene (TPB), perylene, coumarin, rubrene, Nile red, 4-dicyanomethylene-2- Methyl-6-dimethylaminostyryl-4-pyran (DCM), 4-dicyanomethylene-6-Cipidurolidinostyryl-2-tertiarybutyl-4H-pyran (DCJTB), squarylium, aluminum complex (eg, AlQ3), etc. The low molecular weight material can be used.

  Note that an electron injection layer (not shown) is provided on the surface of the light emitting layer in contact with the cathode layer. For the electron injection layer, any one of an oxadizole derivative, a triazole type, and an aluminum complex can be used.

  The cathode layer can be composed of, for example, aluminum (Al), lithium fluoride (LiF), a stack of Al and Ca, a stack of Al and LiF, a stack of Al and Ba, or the like. The cathode layer injects electrons into the light emitting layer through the electron injection layer when a voltage is applied between the cathode layer and the anode layer.

  The anode layer can be made of, for example, indium titanium oxide (ITO) or polyethylene dioxythiophene (PEDOT), which are materials for transparent electrodes. The anode layer injects holes into the light emitting layer by applying a voltage between the cathode layer and the anode layer.

  The cathode layer and the anode layer are electrically connected to the IC circuit portion 7 through wiring not shown.

  When the IC circuit unit 7 performs wireless communication with a reader (to be described later) via the two antenna grips 2 and 2 and receives a signal including tag identification information (hereinafter referred to as tag ID) stored in the IC circuit unit 7. The light emitting unit 6 emits light under the control of the control unit 14 described later.

  FIG. 4 is a block diagram showing a functional configuration of the IC circuit unit 7 and its peripheral circuits.

  The IC circuit unit 7 includes a power supply unit 11 as a power feeding unit, a demodulation unit 12, a modulation unit 13, and a control unit 14 as control means. In addition, a capacitor 16 (not shown in FIGS. 1 to 3), the first switch unit SW1, and the antenna grip 2 are connected to the IC circuit unit 7 in parallel. In FIG. 4, the antenna grip 2 is represented by a coil symbol. Moreover, the light emission part 6 is electrically connected with the control part 14, and the control part 14 switches light emission and quenching based on the control signal output from the control part 14 based on the detection result of 1st switch part SW. .

  In this example, the power supply unit 11 accumulates the energy of the interrogation wave received via the antenna grip 2 and performs wireless power feeding using the energy as a driving power source for the IC circuit unit 7 and the light emitting unit 6. That is, in this embodiment, the IC circuit unit 7 and the antenna grip 2 function as a so-called passive tag.

  The control unit 14 controls the operation of the IC circuit unit 7 via the demodulation unit 12 and the modulation unit 13 and the like, and controls switching of light emission and extinction of the light emitting unit 6 provided outside the IC circuit unit 7. To do.

  The demodulator 12 demodulates the interrogation wave received from the antenna grip 2 from the reader antenna of the reader described later (see FIG. 5 described later).

  The modulation unit 13 modulates the reply signal from the control unit 14 and transmits the response wave from the antenna grip 2 as a signal including a tag ID.

  The control unit 14 includes a storage unit 15 for storing a predetermined information signal therein, and an ID storage area 15a for storing a tag ID for identifying an individual of the IC circuit unit 7 is provided in the storage unit. Is provided. The control unit 14 interprets the reception signal demodulated by the demodulation unit 12 and generates a reply signal based on the information signal stored in the storage unit 15. Then, the modulation unit 13 transmits the reply signal via the antenna grip 2. Further, when receiving the interrogation wave reception signal including its own tag ID from the demodulation unit 12, the control unit 14 supplies power from the power supply unit 11 to the light emitting unit 6 to emit light. Take control.

  The capacitor 16 connected to the outside of the IC circuit unit 7 functions as a bypass capacitor for removing noise generated when the antenna grip 2 receives radio waves.

  As described above, the first switch portion SW1 is in a conductive state in which the two contact terminals 5a and 5b are electrically connected in the normal state in which the open portion 1a of the main body clamping portion 1 is closed (see FIG. 2). At this time, the antenna grip 2 is short-circuited by the first switch SW1 and loses the function of transmitting and receiving radio waves. As described above, since the IC circuit unit 7 functions as a passive tag, power is not supplied from the power supply unit 11 to the control unit 14 or the like unless radio waves are received, and the control unit 14 transmits power from the power supply unit 11 to the light emitting unit. Cannot lead to 6. On the other hand, when the open part 1a of the main body clamping part 1 is open, the two connection terminals 5a and 5b are in a disconnected state (see FIG. 3). At this time, the antenna grip 2 can transmit and receive radio waves. If a radio wave is received, power is supplied from the power supply unit 11 to the control unit 14 and the like, so that the control unit 14 can guide the power from the power supply unit 11 to the light emitting unit 6. As a result of the above, the control unit 14 uses the power obtained from the power feeding unit 11 when the main body clamping unit 1 sandwiches the object, depending on whether the first switch unit SW1 is in a conductive state or a cut-off state. 21 is controlled, and the power supply to the light emitting unit 6 is executed based on the control of the control unit 14. When the main body clamping unit 1 does not hold the object, the control of the RFID circuit unit 21 is stopped and the light emitting unit The tag control and the power supply control to stop the power supply to 6 are executed.

  The IC circuit unit 7 and the antenna grip 2 configured as described above constitute a wireless tag circuit unit 21. The light emitting clip 100 of the present embodiment configured as described above can assemble the object P composed of, for example, a plurality of documents by being sandwiched between the main body sandwiching portions 1, and at that time, the wireless tag circuit portion 21 performs wireless communication. In addition to being in a possible state, the light emission and extinction of the light emitting unit 6 can be controlled.

  Then, for example, when a plurality of sets of objects P arranged in this way are put up against each other, the state shown in FIG. 5 is obtained. In this state, in a normal case, it is difficult to distinguish which object P is seen from the front side in the figure. However, the interrogation wave including the tag ID corresponding to the target object P is transmitted from the reader antenna 201 using the reader 200 capable of wireless communication with the wireless tag circuit unit 21, thereby corresponding to the tag ID. Only the light emitting unit 6 of the light emitting clip 100 can be made to emit light and easily identified.

  Alternatively, although not particularly illustrated, even when the object P made of a single paper document with the light emitting clip 100 sandwiched between them is stored so as to be inserted into a gap between a large book, a file binder, etc., it can be stored easily. The place can be visually confirmed. That is, similarly, by simply transmitting a question wave including a tag ID corresponding to the target object P from the reader 200, the light emitting clip 100 can be easily visually recognized even when there is no illumination and the surrounding is dark. .

  As described above, according to the present embodiment, the operator can easily and reliably find the object P, so that convenience is improved. In particular, since the light emitting part 6 is provided at the bottom of the main body holding part 1, even after the object P is inserted into the U-shaped inside of the main body holding part 1, a visual notification is surely given to the operator. It can be carried out.

  In this embodiment, in particular, the control unit 14 performs light emission control according to the detection result of the first switch SW, and the light emitting unit 6 does not emit light until the light emitting clip 100 is used by the operator. When the object P is sandwiched between the main body holding part 1 and the use of the light emitting clip 100 is started, the light emitting part 6 emits light. Thereby, useless power consumption before use can be prevented. Further, since the RFID circuit unit 21 does not operate when the light emitting clip 100 is not used, it is possible to prevent the RFID circuit unit 21 of the unused light emitting clip 100 from malfunctioning and responding. In addition, when the RFID circuit unit 21 of the light emitting clip 100 sandwiching the object P can store information on the object P in the storage unit 15, the information is transmitted to and received from the reader 200, Information management is also possible.

  In this embodiment, in particular, the power supply unit 11 performs wireless power feeding that accumulates radio wave energy received by the antenna grip 2 and supplies driving power to the entire IC circuit unit 7 and the light emitting unit 6. As a result, even if the RFID circuit unit 21 does not have a self-power supply, the light emitting unit 6 can be fed using the energy of the received radio waves to emit light.

  The present invention is not limited to the above, and various modifications can be made without departing from the spirit and technical idea of the present invention. Hereinafter, such modifications will be described in order.

(1) When a tag antenna is provided separately from the gripping portion In the above embodiment, the antenna grip 2 functions as a tag antenna that connects to the IC circuit portion 7 and performs wireless communication. However, the present invention is not limited to this. I can't. For example, as shown in FIG. 6 corresponding to FIG. 1A, the contact edge portion of the inner cover 3 on which the IC circuit portion 7 is provided is formed by extension, and an appropriate portion is formed on the extension portion 3a. A tag antenna may be configured by providing a loop antenna 17 having a length and connecting it to the IC circuit unit 7. In this case, the two grips 2A corresponding to the two antenna grips 2 of the above embodiment correspond to the gripping portions described in the claims, and the two grips 2A and the main body clamping portion 1 constitute a grip body. . In the case of this light emitting clip 100A, even when the frequency of the radio wave transmitted and received by the RFID tag circuit unit 21 is relatively low, the length of the tag antenna can be sufficiently secured correspondingly.

(2) Other Configurations of Switch Unit In the above embodiment, the first switch unit SW1 is connected to the IC circuit unit 21 in parallel with the antenna grip 2. Then, the first switch part SW1 becomes conductive, the antenna grip 2 is short-circuited to lose its function as a wireless tag, and the first switch part SW1 is turned off to execute the function as a wireless tag, and Although power is supplied to the light emitting unit 6 and the IC circuit unit 7, the present invention is not limited to this.

  For example, as shown in FIG. 7 corresponding to FIG. 4, instead of the first switch part SW1, the second switch part SW2 connected in series with the antenna grip 2 with respect to the IC circuit part 21 is provided with switch means. May be provided on the light emitting clip 100.

  Although detailed illustration of the structure of the second switch unit SW2 is omitted, when the opening 1a of the main body clamping unit 1 is opened, the second switch unit SW2 becomes conductive through an appropriate mechanism. Thereby, the IC circuit part 21 and the antenna grip 2 are conducted. Moreover, when the opening part 1a of the main body clamping part 1 is closed, 2nd switch part SW2 will be in the interruption | blocking state via an appropriate mechanism. For example, as the second switch unit SW2, a known switching element can be used. Thereby, also in this modified example, as described above, the control unit 14 determines whether the power supply unit 11 holds the object in the main body clamping unit 1 depending on whether the second switch unit SW2 is in a conductive state or a cut-off state. The operation of the RFID tag circuit unit 21 is controlled by the power obtained from the power supply and the power supply to the light emitting unit 6 is executed. When the main body clamping unit 1 does not entrap the object, the control of the RFID circuit unit 21 is stopped and the light emission is performed. Tag control and power supply control of stopping power supply to the unit 6 are executed.

  Also by this modification, the same effect as the above-mentioned embodiment is acquired.

(3) In the case of providing a switch unit capable of directly switching power supply to the light emitting unit Further, as shown in FIG. 8, the second switch unit SW2 of the modified example of (2) is connected from the control unit 14 to the light emitting unit 6. You may provide in the electric power feeding path. Also in this case, although the detailed structure of the second switch unit SW2 is omitted, when the opening unit 1a of the main body clamping unit 1 is opened, the second switch unit SW2 becomes conductive through an appropriate mechanism. Thereby, the control part 14 and the light emission part 6 will conduct | electrically_connect, and it will become possible to supply electric power. Moreover, when the opening part 1a of the main body clamping part 1 is closed, 2nd switch part SW2 will be in the interruption | blocking state via an appropriate mechanism. Thereby, the continuity between the control unit 14 and the light emitting unit 6 is cut off, and power feeding is impossible. Therefore, in the present modification, as a result, the control unit 14 obtains from the power feeding unit 11 when the main body clamping unit 1 sandwiches the object, depending on whether the second switch unit SW2 is in a conductive state or a cutoff state. The power supply to the light emitting unit 6 is executed with the generated power, and the power supply control is performed such that the power supply to the light emitting unit 6 is stopped when the main body clamping unit 1 does not pick up the object.

  In the present modification, the wireless tag circuit unit 21 can always wirelessly communicate with the reader 200 regardless of whether the opening part 1a of the main body holding part 1 is closed or opened. On the other hand, as described above, the light emitting unit 6 is allowed to supply power only when the light emitting clip 100 is in a state of use. As a result, it is possible to separately control the switching of power feeding / power supply stopping to the light emitting unit 6 and the switching of operation / non-operation of the RFID tag circuit unit 21.

(4) When a power supply unit capable of self-power supply is provided In the above-described embodiment, a wireless power supply type power supply unit 11 that accumulates the energy of the received interrogation wave and serves as a driving power source for the IC circuit unit 7 and the light emitting unit 6 However, the present invention is not limited to this.

  For example, as shown in FIG. 9 corresponding to FIG. 4, the power supply unit 11 </ b> A provided in the IC circuit unit 7 may be configured by a self-powered built-in battery. In this case, the wireless tag circuit unit 21 functions as a so-called active tag in which the wireless tag circuit unit 21 can always operate regardless of the presence or absence of wireless communication with the reader 200.

  In the present modification, the light emitting unit 6 can be caused to emit light under the control of the control unit 14 described above, using the power supplied from the power supply unit 11A regardless of the presence or absence of wireless communication with the reader 200.

(5) Other,
In the above, the function of the antenna is turned on and off by the switch unit in the modified example of (2) described with reference to the above-described embodiment and FIG. 7, and the switch unit in the modified example of (3) described with reference to FIG. The power supply function to the light emitting unit is turned ON / OFF by the above, but is not limited thereto. That is, any function in the IC circuit unit 7 indicated by functional blocks in FIG. 4 or the like may be turned ON / OFF by an appropriate switch unit. Alternatively, the entire IC circuit unit 7 may be turned ON / OFF.

  In the above description, the arrows shown in FIGS. 4, 7, 8, 9 and the like indicate an example of the signal flow, and do not limit the signal flow direction.

  In addition to those already described above, the methods according to the above-described embodiments and modifications may be used in appropriate combination.

  In addition, although not illustrated one by one, the present invention is implemented with various modifications within a range not departing from the gist thereof.
