  The best mode for carrying out the key storage device according to the present invention will be described below based on the embodiments.

  An embodiment of the present invention will be described with reference to the drawings. First, FIG. 1 is a perspective view of a key storage device of the present invention, and FIG. 2 is a perspective view of a key identification unit of the key storage device. 3 is a side view of the key identification unit with one printed circuit board removed, FIG. 4 is a side view of the keyed holder, FIG. 5 is also a plan view, and FIG. FIG. 7 is a side view showing an enlarged part, FIG. 7 is a side view showing a plurality of examples of different patterns of identifying light transmitting holes in the keyed holder, and FIG. It is a perspective view which shows the relationship with the left and right printed circuit boards which have a transmissive photosensor.

  FIG. 1 is a perspective view showing a key storage device 1 of the present invention with a front door 2 opened. An LED display unit 4, a card reader unit 5, and a numeric keypad 6 are provided on a front panel 3 above the door. Yes. A key identification unit 9 is attached to a plurality of attachment holes 8 formed in the attachment panel 7 inside the key storage device 1. As shown in FIGS. 3 and 4, each key identification unit 9 includes a case main body 10 mounted in the mounting hole 8 and a holder housing portion 11 formed in the front plate 10 a of the case main body 10. A keyed holder 13 with a key 12 attached to the front end, removably inserted from the front, and printed circuit boards 14 and 14 attached to the central part of the case body 10 so as to oppose each other left and right; And a lock mechanism 15 of a holder 13 with a key provided at the rear end of the case body 10.

  The lock mechanism 15 is connected to a solenoid 17 with the telescopic rod 16 facing upward, a central portion is pivotally connected to the telescopic rod 16, and a front end is pivotally attached to the case body 10 so as to be pivotable up and down. The drive arm 18 includes a lock arm 19 which is linked to the front end of the drive arm 18 and whose front end is pivotally attached to the case body 10 so as to be swingable up and down.

  As shown in the side view of FIG. 4 and the plan view of FIG. 5, the keyed holder 13 includes a rectangular vertical plate-shaped identification plate 20 (identification portion) and a front-facing handle attached to the top of the front end. 21. Only the identification plate 20 is fitted in the case body 10 so that the handle portion 21 protrudes forward. The key 12 is attached to the handle portion 21 via a ring 22.

  On the upper surface of the rear end portion of the identification plate 20, a concave groove 23 is formed for engaging and disengaging the lock arm 19 of the lock mechanism 15. As shown in FIG. 3, when the solenoid 17 is not normally operated, the downward claw 19a of the rear end portion of the lock arm 19 is engaged with the concave groove 23, so that the keyed holder 13 is locked. When the solenoid 17 is actuated by a lock release signal and the telescopic rod 16 is pulled downward, the lock arm 19 is turned upward via the drive arm 18 to release the lock of the keyed holder 13.

  At the upper end portion of the identification plate 20 of the holder 13 with the key, four synchronization light transmitting holes 24 (synchronization markers) arranged at regular intervals in the insertion direction are bored in the left-right direction. ing. The translucent hole 24 at the end in the insertion direction is an elliptical hole that is slightly longer in the front-rear direction.

  A virtual lattice pattern 25 having an intersection at a position substantially corresponding to the center of each light transmission hole 24 is formed on the identification plate 20 below each light transmission hole 24, and at an arbitrary intersection, A plurality of identification light transmitting holes 26 (identification markers) are drilled in the left-right direction. As shown in the pattern examples (a) to (d) of FIG. 7, the number of the transparent holes 26 for identification is set so that the number of the transparent holes 26 is unique to each of the plurality of keyed holders 13. Formed differently.

  As shown in a partially enlarged view in FIG. 6, the diameter of each identifying light transmitting hole 26 is slightly larger than that of the synchronizing light transmitting hole 24, and the center of the identifying light transmitting hole 26 is centered. Are slightly shifted in the direction of insertion of the arrow. This is because when the light transmitting hole 24 and the light transmitting hole 26 of the inserted holder 13 with the key are detected by the photo sensor described later, the light transmitting hole 26 for identification is detected slightly earlier, and the identification of the holder 13 with the key is performed. The pattern can be recognized reliably.

  In the present embodiment, the identification light transmitting hole 26 is made slightly faster by configuring both the size of the diameter and the center position of the identification light transmitting hole 26 to be different from those of the synchronization light transmitting hole 24. However, the diameter of the identification light transmission hole 26 is made larger than the diameter of the synchronization light transmission hole 24, and the center of the identification light transmission hole 26 is set to the arrow insertion direction side. If there is any one of the configurations of shifting, the same effect as in the above embodiment can be obtained (see FIG. 6).

  As shown in FIG. 8, one of the opposing surfaces of the front end portions of the printed boards 14 and 14 (for convenience of explanation, they are illustrated to be separated from the left and right) is orthogonal to the insertion direction of the keyed holder 13. The upper and lower three light projectors 27 arranged in the vertical direction are provided on the other side, and the upper and lower three light receivers 28 (detecting means) are provided so as to face each other in pairs. The uppermost light projector 27 and the light receiver 28 facing each other are a transmission type photosensor for synchronization (hereinafter abbreviated as a synchronization photosensor (synchronization sensor)) S1, and are used for synchronization of the uppermost portion of the keyed holder 13. The light transmitting hole 24 is detected.

  The two light projectors 27 and light receivers 28 facing each other at the bottom are identification transmission photosensors (hereinafter abbreviated as identification photosensors (identification sensors)) S2, which are the lattices of the holder 13 with the key. The transparent hole 26 for identification provided in the pattern 25 is detected. Each light projector 27 uses a light emitting element such as an infrared light emitting diode, and each light receiver 28 uses a light receiving element such as a phototransistor.

  Further, a transmission type photosensor S3 including a light projector 27 and a light receiver 28 similar to those described above is provided on the opposing surfaces of the rear end portions of both printed circuit boards 14 and 14, and the photosensor S3 is provided with a key holder 13. The completion of the insertion is detected by detecting whether or not the tip of the wire has passed.

  Further, a transmission type photosensor S4 composed of the same light projector 27 and light receiver 28 is also provided on the opposite surfaces of the upper end portions slightly behind the three light projectors 27 and light receivers 28 on both printed circuit boards 14 and 14. Is provided. This photosensor S4 detects the start of insertion of the keyed holder 13 and the presence of the keyed holder 13 in the holder storage unit 11.

  In the key storage device 1 of the above-described embodiment, for example, a personal authentication card is put on the card reader unit 5, the front door 2 is unlocked and opened, and then the desired keyed holder 13 is held by the ten key 6. When the number is input, the solenoid 17 of the lock mechanism 15 is activated to release the lock, whereby the desired keyed holder 13 can be taken out.

  When returning the keyed holder 13, the personal authentication card is put on the card reader unit 5 to open the front door 2 and the keyed holder 13 is inserted into the holder storage unit 11 as described above. At this time, the synchronizing light transmitting holes 24 formed in the identification plate 20 of the keyed holder 13 and the drilling patterns of the identifying light transmitting holes 26 are respectively represented by the synchronizing photosensor S1 and the upper and lower two. By detecting the photosensors S <b> 2 for identification almost simultaneously, it is authenticated that the keyed holder 13 has been returned to the predetermined regular holder housing 11.

  At the same time, the insertion of the keyed holder 13 is completed by the transmission type photosensor S3, and the insertion start of the keyed holder 13 and the presence in the holder housing 11 are detected by the transmission type photosensor S4. The When these sensors S3 and S4 operate normally, the lock mechanism 15 operates and the keyed holder 13 is locked. As described above, the operation of the lock mechanism 15 can be synchronized with the completion of the return of the keyed holder 13. Even if the keyed holder 13 rattles in the front-rear direction after locking, since the foremost synchronizing transmission hole 24 has an elliptical shape, the inserted signal by the synchronizing photosensor S1 is not interrupted.

  If another holder 13 with a key is inserted into the wrong holder housing 11, an error is generated because the drilling pattern of the light transmitting holes 26 is different. More specifically, when the holder 13 with the key is returned, the solenoid 17 is not operated, and the lock mechanism 15 is operated only by the swinging of the lock arm 19, and a predetermined regular holder storage portion is provided. There is a possibility that it will be accidentally returned to the holder housing 11 which is not 11 (see FIG. 3).

  However, in this embodiment, since it is determined whether or not the keyed holder 13 has been returned to the regular holder storage unit 11, if the keyed holder 13 is returned to the wrong holder storage unit 11, The solenoid 17 is actuated to release the locked state, and an error is generated to notify that the wrong holder storage unit 11 has been inserted (see FIG. 3).

  Furthermore, by synchronizing with the operation of the lock mechanism 15 when the return of the keyed holder 13 is completed, the keyed holder 13 is pulled out immediately after being returned to the regular holder storage unit 11, and the keyed holder In spite of authenticating that the holder 13 has been returned to the holder storage unit 11, it is possible to prevent erroneous authentication that the holder storage unit 11 does not have the keyed holder 13.

  As described above, in the key storage device 1 of the present invention, the light receiver 28 includes the synchronization transmission photosensor S1 and the identification transmission photosensor S2 arranged in a direction orthogonal to the insertion direction of the keyed holder 13. And a plurality of synchronizing light transmitting holes 24 that are detected at regular intervals by the synchronizing transmission type photosensor S1 when the identification plate 20 is inserted into the holder accommodating portion 11, and the synchronizing light transmitting holes. It consists of identification translucent holes 26 having different patterns for each key, which are detected by the identifying transmission photosensor S2 almost simultaneously with any one of 24, and the synchronizing transmission photosensor S1 and the identifying transmission photosensor S2. By detecting the pattern of the synchronization light transmission hole 24 and the identification light transmission hole 26, the plurality of synchronization light transmission holes 24 arranged in the insertion direction in the plurality of key-attached holders 13 and the respective keys. Drilling A plurality of holders 13 with a key are provided with a simple configuration in which transmission holes 26 for identification with different turns are provided, and these light transmission holes 24 and 26 are detected by the synchronization photosensor S1 and the identification photosensor S2. It is possible to centrally manage the presence / absence and storage position.

  In particular, as in the previous embodiment, there are four synchronization light transmission holes 24 and a maximum of eight identification transmission holes 26 in a lattice shape. When detected by the individual identification photosensors S2, 256 types of keyed holders 13 can be managed.

  Further, the identification light transmitting hole 26 is provided at the intersection of the lattice pattern 25, and the pattern of the identification light transmitting hole 26 provided at the intersection is detected by the light receiver 28. Since a large number of patterns of identification translucent holes 26 that are different for each can be formed, a large number of holders with keys can be centrally managed by using a plurality of identification transmission photosensors S2.

  In addition, the synchronization marker and the identification marker are the light transmitting holes 24 and 26 formed in the plate-like keyed holder 13, and the synchronization transmission photosensor S1 and the identification transmission photosensor S2 are Since the transmission type photosensor including the light projector 27 and the light receiver 28 facing each other with the identification plate 20 of the keyed holder 13 interposed therebetween, a plurality of light transmitting holes 24 and 26 are formed in the keyed holder 13. Since the light holes 24 and 25 need only be detected by the general-purpose transmission type photosensor 28, the configuration is simple and the cost can be reduced. In addition, wear of the identification plate 20 can be prevented.

  Further, the synchronization light transmission hole 24 and the identification light transmission hole 26 detected almost simultaneously are detected at the same time after the identification transmission photosensor S2 is detected slightly in the insertion direction. When the identification transparent light sensor S1 and S2 detect the synchronization transparent hole 24 and the identification transparent hole 26 of the inserted holder 13 with the key, the identification transparent light is transmitted. Since the hole 26 can be detected slightly earlier, the pattern of the identification marker of the keyed holder can be reliably recognized. That is, when the synchronization transmission photosensor S1 detects the light that has passed through the synchronization light transmission hole 24, the light that has already passed through the identification light transmission hole 26 has detected the identification transmission photosensor S2. Thus, the undetected state or erroneous detection state of the identifying transmissive photosensor S2 can be prevented.

  In addition, the optical receiver 28 includes a transmission type photosensor S3 that detects whether or not the tip of the keyed holder 13 has passed, thereby detecting the completion of the insertion. Since detection is performed by the transmissive photosensor S3, the presence or absence of the keyed holder 13 is not erroneously recognized and synchronization with the operation of the lock mechanism for the keyed holder 13 can be achieved.

  In addition, the light receiver 28 includes the transmission type photosensor S4 that detects the start of insertion of the keyed holder 13 and the presence of the keyed holder 13 in the holder housing portion 11, so that the presence or absence of the keyed holder 13 is present. Will not be misrecognized.

  Further, the cost of the light receiver 28 can be reduced by using the transmissive photosensors S3 and S4.

  Although the embodiments of the present invention have been described with reference to the drawings, the specific configuration is not limited to these embodiments, and modifications and additions within the scope of the present invention are included in the present invention. It is.

  For example, in the above-described embodiment, a transmission type photosensor includes a sensor that detects the transmission light hole 24 for synchronization and a transmission hole 26 for identification, a sensor that detects the completion of insertion, and a sensor that detects the start and presence of insertion. Although S1 to S4 are used, it is also possible to use a reflective photosensor in which the light emitting element and the light receiving element face the direction of the identification plate 20 and read reflected light from the identification plate 20. When such a reflection type photosensor is used, one of the printed circuit boards 14 becomes unnecessary, so that the key identification unit 9 can be reduced in size.

  In the above embodiment, the number of the light transmitting holes 24 for synchronization is four, and the number of the light transmitting holes 16 for identification can be provided in a lattice shape correspondingly. It goes without saying that the number of holes may be increased or decreased depending on the number of management.

  In the above embodiment, when the desired number of the holder 13 with the key is input by the numeric keypad 6, the solenoid 17 of the lock mechanism 15 is activated and the lock is released. A configuration may be adopted in which the personal identification number of each individual is input and the lock of all the keyed holders 13 permitted to be taken out by each individual is unlocked.

  Moreover, in the said Example, when the holder 13 with a key is inserted in the holder accommodating part 11 different from the holder accommodating part 11 taken out accidentally, it becomes the structure which an error is emitted, but an error is not emitted. Since the holder 13 with the key can be identified by the identification plate 20, the setting may be made such that the holder 13 with the key is managed in a state in which it is inserted into the holder storage part 11 other than the holder storage part 11 taken out. .

It is a perspective view of the key storage apparatus of this invention. Similarly, it is a perspective view of the key identification unit of the key storage device. It is a side view of the key identification unit of the state which removed one printed circuit board. It is a side view of a holder with a key. Similarly, it is a plan view. Similarly, it is a side view which expands and shows a part. It is a side view which shows the example of several patterns from which the translucent hole for identification in a holder with a key differs. It is a perspective view which shows the relationship between the holder with a key, and the right and left printed circuit boards which have several transmissive photosensors.
