Description

  The present invention relates to a crime prevention device for a gaming machine for detecting the unauthorized opening of a frame when a gaming machine such as a pachinko gaming machine is opened by an illegal act.

  A gaming machine such as a pachinko machine includes a control board configured by mounting electronic components such as a ROM, a RAM, and a CPU. In this ROM, information such as a game machine control program created by a game machine manufacturer is written. The gaming machine controls game characteristics such as the number of prize balls paid out and the occurrence frequency of jackpots based on information in the ROM. Generally, the control board is installed on the back side of the gaming machine, and is configured so that the control board cannot be touched from outside unless the middle frame is opened from the outer frame.

  In recent years, after entering the amusement store after closing the store, illegally opening the inner frame from the outer frame of the gaming machine, the regular ROM mounted on the control board is a ROM written with an illegal program (called back ROM Fraudulent activities such as exchanging them are increasing. In order to prevent such illegal acts, it is important to immediately find the back ROM exchanged in the gaming machine. Therefore, means for accurately detecting that the middle frame of the gaming machine has been illegally opened has been proposed (see Patent Document 1).

JP 2001-9137 A (FIGS. 2 and 3)

  The method described in Patent Document 1 is provided with a power supply different from the power supply for operating the internal components of the gaming machine to attach a sensor for detecting the opening and closing of the frame to the gaming machine and to operate the sensor. is there. After the amusement store is closed, all the gaming machines are turned off, but since another power source is provided, it is possible to detect that the frame has been opened by the sensor on the next day or the like.

  After the amusement store is closed, it is common to turn off all power on the island where the gaming machine is installed to save power. However, in the means described in Patent Document 1, it is necessary to prepare another power source dedicated to the sensor for detecting the opening of the frame even when the gaming machine is powered off. There is a problem that wiring is required for the sensor provided in the circuit. That is, wiring all the gaming machines separately from the wiring of the gaming machine main body makes the wiring inside the gaming machine installation island complicated.

  Each gaming machine is provided with a power switch. One island is managed by one breaker. In general, in a game store, when the power supply to the sensor provided in the frame and the power supply to each gaming machine are managed, the power supply is often turned on / off by one breaker. It is impossible to turn on / off the breaker to turn on only the sensor and turn off the power to each gaming machine.

  Therefore, when the power to the sensor is turned “on” and the power to the gaming machine is turned “off”, the power is turned off for each gaming machine one by one. There is a problem.

  The present invention has been made in view of the above disadvantages of the prior art, does not require a power source for the security device itself, and does not detect the opening when the frame is unlocked by legitimate means. An object of the present invention is to provide a crime prevention device for a gaming machine that can reliably detect only the opening of the machine.

Is the gist.

  A gaming machine crime prevention device according to the present invention includes a piezoelectric element, a power generation means including an impact generation unit that applies an impact to the piezoelectric element by an opening operation of the first frame, and a first frame using a voltage generated in the power generation means. Is provided with a transmitting means capable of transmitting an opening signal when it is released from the second frame, so that the piezoelectric element can be used even in a situation where no power is supplied to the gaming machine installation island as in a game shop after closing. An open signal can be generated using a voltage generated by. For example, if this open signal receiver is connected to a hall computer and the reception state of the open signal is recorded, an illegal act of entering after opening the amusement store and opening the first frame to exchange for the back ROM was performed. In this case, the fact that the frame is open can be confirmed, and the discovery of the back ROM can be easily performed.

  Since the gaming machine crime prevention device of the present invention does not require a power source, no wiring is required from the power source to the sensor provided in the frame of the gaming machine, and wiring inside the gaming machine installation island does not become complicated.

  In addition, since the gaming machine crime prevention device of the present invention does not require a power source to transmit an opening signal, even after the game store is closed, even if the power on the island where gaming machines are installed is collectively turned off by the breaker, the illegal act It is possible to confirm. Since it is not necessary to turn the power to the sensor “on” and the power to the gaming machine “off”, it is possible to save the trouble of powering off each gaming machine one by one.

  The gaming machine crime prevention apparatus further includes a collision preventing means for preventing the collision member from colliding with the piezoelectric element when the locking of the first frame is unlocked by a regular means. In the case where the member is prevented from colliding with the piezoelectric element and the piezoelectric element is configured not to generate power, it is possible to reliably detect only the opening signal of the illegal act.

  Further, in the crime prevention device of the gaming machine, the locking device includes a rotating body that rotates in conjunction with a keyhole, and a piezoelectric element protection plate that displaces in conjunction with the rotation of the rotating body, When the locking device is locked, it is displaced to a position other than between the piezoelectric element and the collision member. When the locking device is unlocked, it is displaced to a position between the piezoelectric element and the collision member. If the frame is opened using a key, the piezoelectric element protection plate is displaced to a position between the collision member and the piezoelectric element in conjunction with the key hole, so that the frame is opened. Even in this case, since the collision member does not collide with the piezoelectric element, no release signal is generated. Therefore, it is possible to reliably detect only the opening of the frame body in an unauthorized act.

  The gaming machine crime prevention device further includes a rotating body that rotates in conjunction with the keyhole of the locking device and that displaces the impact generating unit in conjunction with the rotation, and the rotating body locks the locking device. In this state, the impact generating portion is displaced to a position where the collision member collides with the piezoelectric element due to the vibration, and in a state where the locking device is unlocked, the collision member does not collide with the piezoelectric element due to the vibration. When the shock generating part is configured to be retracted, when the frame is opened using a key, the rotating member rotates to displace the elastic member, resulting in the generation of an impact fixed to the elastic member. Since the part retreats to a position where it does not collide with the piezoelectric element, no release signal is generated. Therefore, it is possible to reliably detect only the opening of the frame body in an unauthorized act.

Can be opened.

  4 (a) to 4 (d) show examples of a security device for a middle frame as a first embodiment of the present invention. 4A to 4D are views of the pachinko machine viewed from the back side. In the security device for the middle frame, the first frame is the middle frame and the second frame is the outer frame. The security device is attached to the back side of the middle frame 3. As shown in FIGS. 4 (a) and 5 (a), the security device has a piezoelectric element P that generates electric power by generating distortion caused by the impact, and an impact on the piezoelectric element P by the opening operation of the inner frame 3. Power generation means comprising an impact generating portion to be applied, and transmission means D capable of transmitting an open signal when the middle frame 3 is released from the outer frame 2 using a voltage generated in the power generation means.

  As shown in FIGS. 4A to 4D, the impact generating portion supports the iron ball 8 as a collision member for causing the piezoelectric element P to collide and applying distortion, and the iron ball 8 to support the inner frame 3. It is comprised from the leaf | plate spring 9 as an elastic member formed so that the iron ball 8 might collide with the piezoelectric element P by vibrating with opening operation | movement. The leaf spring 9 has an iron ball 8 attached near the top end and is bent downward. As shown in FIG. 4D, the lower part from the bent part of the leaf spring 9 is joined to the back surface of the base body 61 of the locking device. On the other hand, as shown in FIG. 5A, the leaf spring 9 is attached so as to be spaced from the piezoelectric element P from above the bent portion including the attaching portion and the tip end portion of the iron ball 8.

  Further, as a mechanism for vibrating the leaf spring by the middle frame opening operation in the impact generating portion, as shown in FIGS. 5A to 5D, the leaf spring is placed at a predetermined position on the inner surface of the right side wall of the outer frame 2. A locking piece 10 is attached. As shown in FIGS. 5 (a) to 5 (d), the leaf spring locking piece 10 is formed in the shape of a hook and can be locked to the tip of the leaf spring 9, and the middle frame is opened. As a result of the vibration of the leaf spring 9, the iron ball 8 gives an impact to the piezoelectric element P.

  As shown in FIG. 5A, when the middle frame 3 is closed with respect to the outer frame 2, the tip of the leaf spring 9 is locked by a leaf spring locking piece 10 fixed to the outer frame 2. ing. As shown in FIG. 5 (b), when the middle frame 3 is released from the outer frame 2 to a certain distance H1, the tip of the leaf spring 9 is locked by the leaf spring locking piece 10, so that it is flexed by elasticity. It becomes a state.

  When the middle frame 3 is further opened from the outer frame 2 to a predetermined distance H2 as shown in FIG. 5C, the tip of the leaf spring 9 is disengaged from the tip of the leaf spring locking piece 10, and the leaf spring. 9 vibrates in the front-rear direction (left-right direction in the figure) of the pachinko machine 1 due to the force of return of bending. When the leaf spring 9 vibrates back and forth, the iron ball 8 attached to the leaf spring 9 collides with the piezoelectric element P and gives an impact. Due to this impact, the piezoelectric element P is distorted to generate electricity. The generated voltage is supplied to the transmitting means D connected to the piezoelectric element P, and the transmitting means D transmits an open signal.

  When the middle frame 3 is closed to the outer frame 2, as shown in FIG. 5A, the tip of the leaf spring 9 returns to the state where it is locked to the hook-like portion at the tip of the leaf spring locking piece 10.

  The piezoelectric element P may be any element that can convert mechanical energy generated by the impact of an iron ball collision into electrical energy, and inorganic or organic elements can be used. For example, a piezoelectric ceramic element of PZT (piezoelectric ceramics) type can be mentioned. A piezoelectric ceramic element is an element that has a piezoelectric property by applying a DC high voltage to a polycrystalline body to generate remanent polarization.

  When the voltage is generated by the piezoelectric element P, the transmitting means D is formed with a circuit so as to transmit an open signal using the voltage. The transmitting means D is formed so that an open signal transmitted from the transmitting means D is received by a receiver connected to the hall computer.

  Further, in the crime prevention device shown in FIG. 4, when the locking device 6 is unlocked by the proper means (using the key 6d), the piezoelectric element P is prevented from generating power and the release signal is released. Is provided with a locking means for preventing the transmission of. As shown in FIGS. 4A to 4D, the locking means is attached to a rotating body 7 interlocked with the locking device 6 and is movable up and down, and a crank 11 for preventing vibration of the leaf spring 9; The guide member 12 guides the movement of the crank 11. The crank 11 is formed of a long plate-like body, and is provided with a guide portion 11a in the middle thereof. The lower end is formed as an L-shaped fixing portion 11b. Further, the guide member 12 is provided with a guide groove 12a with which the guide portion 11a of the crank is engaged.

  4A and 4C show a state where the locking device 6 is locked, and FIGS. 4B and 4D show a state where the locking device 6 is unlocked using a key 6d. As shown in FIGS. 4A and 4C, in a state where the locking device 6 is locked (a state in which the normal inner frame 3 and the outer frame 2 are closed), the crank fixing portion 11 b is attached to the leaf spring 9. It is displaced to the position to release the fixation. The fixed portion 11b at the tip of the crank 11 is located above the leaf spring 9 so as not to cover the leaf spring 9 at all.

  On the other hand, as shown in FIGS. 4B and 4D, in a state where the locking of the middle frame 3 of the locking device 6 is unlocked using a key (the state is unlocked by a regular means). The crank fixing portion 11b is displaced to a position on the leaf spring locking piece 10 side of the leaf spring 9 on the back side of the gaming machine. When the key 6d is inserted into the key hole of the cylinder lock 6c of the locking device 6 and rotated clockwise when viewed from the front surface of the pachinko machine 1, it is unlocked by locking the inner frame locking member 62a of the first locking mechanism, 62a moves downward and disengages from the locking pieces 64a and 64a provided on the outer frame 2 (see FIGS. 1 and 2). At the same time, the rotating body 7 that rotates in conjunction with the keyhole also rotates in the counterclockwise direction (in the direction of arrow R in the figure when viewed from the back of the gaming machine) in conjunction with the cylinder lock 6c. The crank 11 connected to the rotating body 7 engages with the guide groove 12a of the guide member 12, and the fixed portion 11b at the tip moves obliquely downward.

  As shown in FIGS. 4B and 4D, at this time, the fixed portion 11b at the lower end of the crank 11 is positioned so as to cover the upper side of the leaf spring 9, but the upper end of the leaf spring 9 is not covered. Is formed. Therefore, the crank 11 does not prevent the upper end of the leaf spring 9 from being locked by the leaf spring locking piece 10.

  FIG. 5 (d) shows a state where the key 6 d of the locking device is rotated and unlocked to release the middle frame 3 from the outer frame 2. As shown in the figure, when the key 6d is used for unlocking, the rotating body 7 rotates and the fixing portion 11b of the crank 11 covers the upper portion of the leaf spring 9, and the movement of the leaf spring 9 is restricted. When the middle frame 3 is opened in this state, the leaf spring locking piece 10 cannot pull the upper end of the leaf spring 9, and the leaf spring locking piece 10 is unlocked. That is, the plate spring 9 does not vibrate because the plate spring locking piece 10 is detached from the plate spring 9 without the plate spring 9 being bent. Even if the tip of the leaf spring 9 is slightly bent, the bending to such an extent that the leaf spring 9 itself vibrates does not occur. When the vibration of the leaf spring 9 is prevented, the iron ball 8 provided on the leaf spring 9 is prevented from colliding with the piezoelectric element P. Since the iron ball 8 does not collide with the piezoelectric element P and no power is generated, no opening signal is generated even if the middle frame 3 is opened.

  On the other hand, when the middle frame is opened without using the key 6d of the locking device, as described with reference to FIGS. 5A to 5C, the rotating body 7 does not rotate unless the key is used. In addition, since the leaf spring 9 is not fixed by the crank fixing portion 11b, it is possible to transmit an opening signal when the middle frame is opened. In order to open the middle frame 3 illegally without using a key, a special tool or the like is used, and the middle frame locking collar members 62a, 62a and the outer frame 2 locking pieces 64a, It is assumed that the engagement with 64a is released.

  6 (a), 6 (b), 7 (a), and 7 (b) show a second embodiment of the present invention and show an example of a security device for a front frame. 6A, 6B, 7A, and 7B are views of the pachinko machine viewed from the back side. In the security device for the front frame, the first frame is the front frame and the second frame is the middle frame. As shown in FIGS. 6 (a) and 7 (a), this crime prevention device has a power generating means and a transmitting means D, each comprising a piezoelectric element P, an iron ball 8, a leaf spring 9, etc., attached to the back side of the middle frame 3. ing. A plate spring locking piece 10 for locking the vicinity of the upper end of the plate spring 9 is attached to the back side of the front frame 4, and the plate spring 9 is pulled from the front side of the pachinko machine more than the middle frame 3 to add deflection. It is configured as follows.

  As shown in FIG. 7A, the leaf spring locking piece 10 is configured to lock the leaf spring 9 attached to the back side of the middle frame through the opening 13 of the middle frame 3. The leaf spring locking piece 10 has a hook shape at the tip, and is formed so as to hook the vicinity of the tip of the leaf spring 9 from the side surface direction.

  As shown in FIGS. 6A and 7A, the rotating body 7 has a protruding piece 14 extending so as to protrude from the side surface of the rotating body 7. The rotating body 7 is formed so that the projecting piece 14 can push down a slide member 15 attached so as to be slidable up and down. The slide member 15 is provided with an unlocking portion 15a for pushing down the front frame unlocking piece 67b and a fixing portion 15b for fixing the upper end of the leaf spring 9.

  In a state where the front frame is closed, the front frame locking collar members 62b and 62b are always pressed upward. The front frame unlocking piece 67b is pressed upward in conjunction with the front frame locking collar member 62b. As a result, when the front frame 4 is closed, the slide member 15 is pressed upward by a spring or the like.

  FIGS. 8A to 8D are explanatory views of the operation of the second embodiment of the security device shown in FIGS. First, as shown in FIG. 8A, when the middle frame 3 and the front frame 4 are closed, the tip of the leaf spring 9 is locked by a leaf spring locking piece 10 fixed to the front frame 4. Yes. FIG. 8A shows a state in which the locking device 6 is locked, and the slide member 15 that fixes the leaf spring 9 is displaced to a position above the leaf spring 9 so that the leaf spring 9 can freely vibrate. It is in.

  When the front frame 4 is released from the state in which the front frame 4 is locked to the middle frame 3 to a certain distance H3 without fixing the plate spring 9 as shown in FIG. Since it is locked by the leaf spring locking piece 10, it is bent due to elasticity. This state is a case where the front frame 4 is opened by unauthorized means by pressing down the front frame unlocking piece 67b with a special tool or the like without using a key.

  Next, as shown in FIG. 8C, when the front frame 4 is further opened from the middle frame 3 to a predetermined distance H4, the tip of the leaf spring 9 is disengaged from the tip of the leaf spring locking piece 10, The leaf spring 9 vibrates in the front-rear direction (left-right direction in the figure) of the pachinko machine 1 due to the force to return the deflection. When the leaf spring 9 vibrates in the front-rear direction of the pachinko machine 1, the iron ball 8 attached to the leaf spring 9 collides with the piezoelectric element P and gives an impact, the piezoelectric element P generates electric power, and the transmitting means D generates an open signal. To send. When the front frame 4 is pushed into the middle frame 3 and closed, the elasticity of the leaf spring 9 returns the state where the upper end of the leaf spring 9 is locked to the locking portion at the tip of the leaf spring locking piece 10.

  When the front frame is opened by unlocking (using regular means) using a key, as shown in FIGS. 6B, 7B, and 8D, the upper end of the leaf spring 9 is used. Is fixed to the fixing portion 15 b of the slide member 15, the front frame 4 is released from the middle frame 3. When the key 6d is inserted into the key hole of the cylinder lock 6c and turned counterclockwise when viewed from the front of the pachinko machine, the rotating body 7 rotates in conjunction with the cylinder lock 6c as shown in FIG. When viewed from the front of the pachinko machine, it rotates counterclockwise (FIGS. 6 and 7 show the state viewed from the back of the pachinko machine, so that the rotating body 7 rotates clockwise in the figure). The protruding piece 14 of the body 7 pushes down the slide member 15. The slide member 15 is provided on the rear side of the front frame 4 by pushing down the front frame unlocking piece 67b and moving the front frame locking collar member 62b connected to the front frame unlocking piece 67b downward. The front frame 4 is released from the middle frame 3 by detaching from the locking piece.

  At this time, the lowered slide member 15 is displaced to a position where the tip of the fixing portion 15b holds and fixes the tip of the leaf spring 9, and the movement of the leaf spring 9 is locked. Even if the front frame 4 is opened in this state, as shown in FIG. 8D, the leaf spring locking piece 10 is released from the locking state without pulling the upper end of the leaf spring 9. As a result, the leaf spring 9 does not vibrate because the leaf spring 9 is not deflected, and the iron ball 8 does not collide with the piezoelectric element P and cannot generate electric power. Therefore, the transmitting means D does not emit an opening signal.

  FIGS. 9-11 is a modification of a 1st embodiment, and is an Example of the crime prevention apparatus with respect to unauthorized opening of a middle frame. The difference from the first embodiment is that, in the first embodiment, as shown in FIG. 4, the fixing portion 11 b of the crank 11 is located on the outer frame 2 side behind the leaf spring 9 and is pulled by the leaf spring locking piece 10. 9 (b) and 10 (b), when the lock is unlocked using a key, the collision preventing portion 11d at the tip of the crank 11 is piezoelectric. The piezoelectric element is configured so as not to generate power by being displaced so as to be positioned between the element P and the iron ball 8 and preventing the iron ball 8 from colliding with the piezoelectric element P. When the locking device is locked, as shown in FIGS. 9 (a) and 10 (a), the crank 11 is displaced to an obliquely upper position so that the collision preventing portion 11d is connected to the piezoelectric element P, the iron ball 8, and the like. It is in a state of being evacuated from between.

  As shown in FIG. 11A, in a state where the locking device is locked and the middle frame 3 is closed, the collision preventing portion 11d of the crank 11 is in a position that does not prevent the iron ball 8 from colliding with the piezoelectric element P. When the inner frame is opened by unauthorized means without unlocking the locking device, the leaf spring 9 is bent by the leaf spring locking piece 10 as shown in FIG. The generated ball vibrates, the iron ball 8 collides with the piezoelectric element P, generates electric power, and an open signal is transmitted from the transmitting means D.

  On the other hand, when the middle frame is opened after unlocking using the key, as shown in FIGS. 9B, 10B and 11C, the key 6d is rotated. While the locking of the inner frame locking hook member 62a is released, the rotating body 7 rotates in conjunction with the key 6d and the crank 11 descends obliquely, so that the collision preventing portion 11d at the lower end of the crank 11 is moved to the iron ball 8 And the piezoelectric element P. When the middle frame 3 is opened, the leaf spring locking piece 10 fixed to the outer frame 2 bends the tip of the leaf spring 9 to generate vibration. However, the collision preventing portion 11d of the crank 11 is located between the iron ball 8 and the piezoelectric element P to prevent the iron ball 8 from colliding with the piezoelectric element P, and the piezoelectric element P does not generate power and no release signal is transmitted. Therefore, when unlocking with proper means using a key, the collision preventive means prevents the collision member from colliding with the piezoelectric element, the piezoelectric element does not generate electricity and no release signal is transmitted, and fraud Since the release signal is transmitted only when the middle frame is opened, it is possible to easily detect only the middle frame opening in the fraudulent act.

  FIGS. 12-14 is a modification of 2nd embodiment, and is an Example of the crime prevention apparatus with respect to unauthorized opening of a front frame. The difference from the second embodiment (FIGS. 6 to 8) is that, in the second embodiment, the fixed portion 15b of the slide member 15 holds the tip of the leaf spring 9 as shown in FIG. In the case where the movement of the leaf spring 9 is locked while being displaced to the fixing position, as shown in FIGS. 12 (b) and 13 (b), when the key is unlocked, The plate member 16 is displaced so as to be positioned between the iron ball 8 and the piezoelectric element P so that the iron ball 8 does not collide with the piezoelectric element P, so that the piezoelectric element does not generate power. It is configured.

  12 (a), 12 (b), 13 (a), and 13 (b), the plate member 16 is provided with an inclined surface 16a on the left side in the drawing, and the bottom surface has a slide groove 17 in the horizontal direction in the drawing. It is formed to move to. The slide member 15 interlocked with the protrusion 14 of the rotating body 7 has an unlocking portion 15a for pressing the front frame unlocking piece 67b downward, and a plate member abutting portion abutting on the inclined surface 16a of the plate member 16. 15e. When the slide member 15 slides downward by the projecting piece 14 of the rotating body 7, the plate member contact portion 15 e acts on the slope of the plate member 16, and the plate member 16 moves toward the iron ball 8 along the slide groove 17 ( Move to the right in the figure).

  In the state where the front frame 4 is locked, the plate member 16 is formed so as to be urged to the left side in the drawing by a spring or the like as shown in FIG.

  As shown in FIGS. 12A and 13A, the plate member 16 is retracted from between the iron ball 8 and the piezoelectric element P in a state where the locking device is locked and the middle frame 3 is closed. The iron ball 8 is displaced to a position that does not prevent the iron ball 8 from colliding with the piezoelectric element P. If an attempt is made to open the inner frame from this state by unauthorized means, the leaf spring 9 is deflected by the leaf spring locking piece 10 and vibrates, and the iron ball 8 collides with the piezoelectric element P to generate power, and the release signal is generated. It is transmitted from the transmission means D.

  As shown in FIGS. 12 (b), 13 (b), and 14, when the front frame is opened after being unlocked using the key, the front frame locking hook member is rotated by rotating the key. Is released, the rotating body 7 rotates in conjunction with the key, the slide member 15 descends, the plate member contact portion 15e contacts the inclined surface 16a of the plate member 16, and the plate member 16 is slid. It is moved along the groove 17 to be displaced between the iron ball 8 and the piezoelectric element P.

  When the front frame 4 is opened, as shown in FIG. 14, the leaf spring locking piece 10 fixed to the front frame 4 pulls the tip of the leaf spring 9 and opens the front frame 4 more than a predetermined amount, Even if the leaf spring locking piece 10 is released and the leaf spring 9 vibrates, the plate member 16 is positioned between the iron ball 8 and the piezoelectric element P, so that the collision of the iron ball 8 with the piezoelectric element P is prevented. No power generation occurs and no release signal is transmitted from the transmission means D. In this way, when the front frame 4 is opened by unlocking with regular means, the opening signal is not transmitted, and the opening signal is transmitted only when the front frame 4 is opened by fraud. The opening of the front frame 4 can be easily detected.

  15-17 is a modification of a 1st embodiment, and is an Example of the crime prevention apparatus with respect to unauthorized opening of a middle frame. The difference from the first embodiment is that, as shown in FIGS. 15 (b) and 16 (b), the portion below the bent portion of the leaf spring 9 is directly joined to the base body 61. When the plate spring support member 18 is joined and unlocked using a key, the plate spring support member 18 moves downward, and as shown in FIG. The plate spring locking piece 10 is disengaged, the plate spring 9 is not vibrated, and the piezoelectric element P is configured not to generate electricity. In the state where the locking device is locked, the leaf spring 9 is locked with the upper end of the leaf spring 9 as shown in FIG. In this case, the leaf spring 9 is configured to vibrate.

  As shown in FIGS. 15A and 16A, the leaf spring 9 is fixed to the support portion 18 a of the leaf spring support member 18 at a portion below the bent portion. The leaf spring support member 18 is biased upward using a spring or the like (not shown). A crank 11 is attached to the rotating body 7 so as to move up and down according to the rotation. The lower end of the crank 11 is in contact with the upper end of the leaf spring support member 18, and the leaf spring support member 18 is also lowered when the crank 11 is lowered.

  As shown in FIG. 17 (a), in a state where the middle frame 3 is closed, the leaf spring support member 18 is biased upward, and the iron ball 8 is displaced to a position where it collides with the piezoelectric element P. The leaf spring locking piece 10 locks the tip of the leaf spring 9. If an attempt is made to open the middle frame from this state by unauthorized means, as shown in FIG. 17 (b), the leaf spring 9 vibrates due to bending by the leaf spring locking piece 10, and the iron ball 8 is moved to the piezoelectric element. It collides with P and generates power, and an opening signal is transmitted from the transmitting means D.

  On the other hand, when the middle frame is opened after unlocking using the key, as shown in FIGS. 15 (b), 16 (b) and 17 (c), when the key 6d is rotated, the middle frame is opened. While the frame locking collar member 62a is unlocked, the rotating body 7 rotates in conjunction with the key 6d, the crank 11 descends, and the leaf spring support member 18 that contacts the lower end of the crank 11 is pushed downward. . Since the leaf spring 9 is fixed to the leaf spring support member 18, the leaf spring 9 is also lowered together. As a result, the leaf spring locking piece 10 is released from the leaf spring 9 and the iron ball 8 fixed to the leaf spring 9 is also retracted to a position where it does not collide with the piezoelectric element P.

  When the middle frame 3 is opened using the key in this manner, the leaf spring latching piece 10 fixed to the outer frame 2 is unlocked. Therefore, even if the middle frame 3 is opened, the tip of the leaf spring 9 is released. The leaf spring 9 does not vibrate and no open signal is generated. When unlocked by proper means, the plate spring support member 18 is displaced and the state in which the plate spring 9 is locked to the plate spring locking piece 10 is released to prevent the plate spring 9 from vibrating. The piezoelectric element P does not generate power and does not transmit an open signal, and is configured so that an open signal is transmitted only when the middle frame is opened by fraud. It can be constituted as follows.

  18-20 is a modification of 2nd embodiment, and is an Example of the crime prevention apparatus with respect to unauthorized opening of a front frame. The difference from the second embodiment (FIGS. 6 to 8) is that, as shown in FIGS. 18 (b) and 19 (b), the portion below the bent portion of the leaf spring 9 is directly on the base 61. Is attached to the leaf spring support member 18, and when unlocked using a key, the leaf spring support member 18 moves downward and is attached to the leaf spring support member 18. Since the plate spring 9 is also displaced downward, the plate spring 9 and the plate spring locking piece 10 are unlocked so that the plate spring 9 does not vibrate and the piezoelectric element P does not generate electricity. In the state in which the locking device is locked, the leaf spring 9 is locked by the leaf spring locking piece 10 by locking the upper portion of the leaf spring 9 and releasing the front frame 4 as shown in FIG. 9 is configured to vibrate.

  As shown in FIG. 18A, the leaf spring 9 is fixed to the leaf spring support member 18 at a portion below the bent portion. The leaf spring support member 18 is formed integrally with the slide member 15. The leaf spring support member 18 is biased upward using a spring or the like (not shown). As shown in FIGS. 18B and 19B, when the rotating body 7 rotates and the protruding piece 14 pushes down the slide member 15, the leaf spring support member 18 formed integrally with the slide member 15 is also formed. The leaf spring 9 is lowered together.

  In a state where the front frame 4 is closed, the leaf spring support member 18 is biased upward, the iron ball 8 is displaced to a position where it collides with the piezoelectric element P, and the leaf spring locking piece 10 is moved to the leaf spring 9. (See FIGS. 18 (a) and 19 (a)). If an attempt is made to open the front frame 4 by unauthorized means, the leaf spring 9 is locked by the leaf spring locking piece 10, so that it bends and vibrates, and the iron ball 8 collides with the piezoelectric element P to generate power. Then, an open signal is transmitted from the transmission means D.

  On the other hand, when the front frame 4 is opened after unlocking using the key, the key 6d is rotated as shown in FIGS. 18 (b), 19 (b) and 20 (b). The front frame locking hook member 62b is unlocked, and the rotating body 7 is rotated in conjunction with the key 6d so that the protruding piece 14 pushes the slide member 15 downward. Since the slide member 15 and the leaf spring support member 18 are integrated, the leaf spring support member 18 is also pushed downward. Since the leaf spring 9 is fixed to the leaf spring support member 18, the leaf spring 9 is also lowered together. Then, the plate spring locking piece 10 is released from the plate spring 9 and the iron ball 8 fixed to the plate spring 9 is also retracted to a position where it does not collide with the piezoelectric element P.

  When the front frame 4 is opened using the key in this way, the leaf spring 9 is lowered and the leaf spring locking piece 10 is unlocked. Therefore, even if the front frame 4 is opened, the leaf spring is released. Since the leaf spring 9 does not vibrate without bending at the tip of 9, no open signal is generated. In this way, when unlocked by proper means, the plate spring support member is displaced and the state where the plate spring is locked to the plate spring locking piece is released, so that the plate spring does not vibrate. Therefore, it is configured so that the opening signal is transmitted only when the front frame is opened by fraudulent acts so that the piezoelectric element does not generate power and the opening signal is not transmitted. it can.
