Description

  The present invention relates to a prize acquisition game machine and a prize acquisition game system provided with a catcher unit for holding a prize such as a crane game machine.

  In general, a crane game machine is widely known as a prize acquisition game. In the crane game machine, a plurality of prizes are piled up on a game field in a case, and a prize can be obtained by operating a gripping device (catcher unit) from the piled up game machines. Normally, in a crane game machine, after the gripping device is moved to a position above the target prize, it is lowered by the lifting device to grip the prize, and then raised again to the prize payout port. .

  In such a crane game machine, the catcher part is lowered by sending out a wire that suspends the gripping device. Then, by detecting the looseness of the wire when the gripping device is pressed against the prize or reaches the field floor, the rotation of the motor that sends out the wire is stopped to stop the lowering of the gripping device, and the prize is The operation for gripping is started.

  Moreover, in the crane game machine described in patent document 1, a rotating shaft is rotated with the stepping motor of a raising / lowering apparatus, a wire is unwound from a winding pulley, and a holding | grip apparatus is lowered. Then, the gripping device descends, the arm claw member comes into contact with either the floor or the prize, and the claw member moves upward relative to the arm. The operation shifts to holding.

Next, the detailed structure of the catcher part 14 in this embodiment is demonstrated.
FIG. 3 is an external view showing the structure of the catcher unit 14 in an exploded manner. The catcher unit 14 houses an arm opening / closing mechanism 14a inside a cover 14c. The arm opening / closing mechanism 14a is suspended by a wire 39 and connected to a cable (not shown) for inputting a control signal. The arm opening / closing mechanism 14a controls the opening / closing of the two arms 14b in response to a signal from the catcher driving unit 35. Further, the catcher portion 14 of the present embodiment is provided with a unit attachment 14d for attaching the weight attachment unit 14e. The unit fixture 14d is provided, for example, on both side surfaces of the arm opening / closing mechanism 14a on the same line as the opening / closing direction of the arm 14b. The unit attachment 14d is provided with an attachment rod 14f that can be penetrated through a hole provided in the weight 14g, so that the weight 14g can be attached and detached.

  FIG. 4 is a view showing a state in which the weight 14g is attached by the weight attaching unit 14e provided in the catcher portion 14. As shown in FIG. As shown in FIG. 4, the weight 14g is attached to the catcher portion 14 by passing the attachment rod 14f of the weight attachment unit 14e through the hole of the weight 14g. A weight 14g can be arbitrarily attached to and detached from the mounting rod 14f. Therefore, the weight of the catcher portion 14 as a whole can be adjusted by adjusting the number of weights 14g attached to the weight mounting unit 14e. Thereby, the pressing pressure with respect to the prize when the catcher part 14 is moved downward can be adjusted.

Next, a detailed configuration of the catcher up / down moving mechanism 40 that moves the catcher unit 14 in the up / down direction will be described.
5 and 6 are diagrams showing the configuration of the catcher up-and-down moving mechanism 40 in the present embodiment. The catcher up / down moving mechanism 40 shown in FIGS. 5 and 6 has the same mechanism for moving the catcher unit 14 in the vertical direction, but the configuration of the stress sensor 37 for detecting the stress level by the catcher unit 14 is different. .

  As shown in FIG. 5, the catcher up-and-down moving mechanism 40 is provided with a wire take-up pulley 41 for adjusting the length of the wire 39 that suspends the catcher portion 14. A wire 39 introduced through a roller 43 provided in the vicinity of one end of the tension arm 42 is wound around the wire take-up pulley 41. The tension arm 42 is provided with a roller 43 near one end in the longitudinal direction and a spring mounting member 46 near the other end. The tension arm 42 is provided with a rotation shaft 45 at the center in the longitudinal direction, and can rotate within a predetermined range.

  A spring 48 is attached as an elastic member between the spring attachment member 46 and a spring attachment member 47 attached at a fixed position. The spring 48 is biased in a direction to lower the end of the tension arm 42 on the side where the spring mounting member 46 is provided. In a state where the catcher unit 14 has not reached the prize (or the floor surface of the play field 11), the weight of the catcher unit 14 is applied to the roller 43 as shown in FIG. In balance, the tension arm 42 is substantially horizontal. On the other hand, when the catcher unit 14 reaches the premium (or the floor surface of the play field 11) and has a reaction force, the weight applied to the roller 43 is lighter than that of the catcher unit 14, and FIG. ), The side on which the spring attachment member 46 is attached is lowered by the urging force of the spring 48.

  In the configuration shown in FIG. 5, a plurality of photocouplers 50 a and 50 b are provided as the stress sensor 37. The photocoupler 50a is provided with a light emitting unit 50a1 and a light receiving unit 50a2. The light output from the light emitting unit 50a1 is received by the light receiving unit 50a2. A light shielding plate 49 is provided at the end of the tension arm 42 on the side where the spring mounting member 46 is provided, and the light shielding plate 49 is disposed so as to pass between the light emitting unit 50a1 and the light receiving unit 50a2. Yes.

  When the tension arm 42 is in a substantially horizontal state, the light shielding plate 49 is positioned between the light emitting unit 50a1 and the light receiving unit 50a2 of the photocoupler 50a disposed on the upper side, and the light output from the light emitting unit 50a1 is transmitted. Cut off.

  When the catcher unit 14 is lowered and pressed against a prize or the like, the light shielding plate 49 moves downward as shown in FIG. 7B. In this state, the light output from the light emitting unit 50a1 of the photocoupler 50a is received by the light receiving unit 50a2. On the other hand, in the photocoupler 50b disposed in the lower part, the light shielding plate 49 is positioned between the light emitting unit and the light receiving unit, so that the light output from the light emitting unit does not reach the light receiving unit.

  Further, when the wire 39 is loosened by the lowering of the catcher portion 14, the light shielding plate 49 further moves downward. In this state, in each of the photocouplers 50a and 50b, the light output from each light emitting unit is received by the corresponding light receiving unit.

  In this way, by forming the stress sensor 37 by the plurality of photocouplers 50a and 50b, the tension arm 42 of the tension arm 42 depends on which photocoupler 50a and 50b receives the light output from the light emitting unit. The amount of rotation can be detected in a plurality of stages.

  In the configuration shown in FIG. 6, a rotor switch 51 that detects the amount of rotation of the tension arm 42 is provided on the rotation shaft 45 of the tension arm 42. The rotor switch 51 outputs a signal corresponding to the amount of rotation of the tension arm 42. The other configuration is the same as that shown in FIG.

  Thus, by providing the rotor switch 51 on the rotation shaft 45, the rotation amount of the tension arm 42 can be detected at a plurality of stages that can be detected by the rotor switch 51.

  The configuration of the stress sensor 37 shown in FIGS. 5 and 6 is an example, and other configurations can be used as long as the rotation amount of the tension arm 42 can be detected.

Next, the operation of the prize acquisition game system (host device 6, crane game machine 10) in the present embodiment will be described.
In the crane game machine 10 according to the present embodiment, as a method for setting a threshold value of a stress level by the catcher unit 14, (1) a first method set by an operation of an administrator or the like, and (2) a lottery setting at the time of game execution (3) a third method that is set according to the game mode instructed by the player, and (4) a fourth method that is set according to the payout rate. The methods (1), (2), (3), and (4) will be described below with reference to flowcharts.

  (1) A first method of setting by an operation of an administrator or the like.

  In this method, an administrator (or an operator) who manages the crane game machine 10 can arbitrarily set how much pressure is applied to the prize by the catcher unit 14 in the crane game machine 10. Therefore, the pressure applied by the catcher unit 14 can be changed according to the type (size, shape, material, etc.) of the prize put in the play field 11 of the crane game machine 10. As a result, it is possible to adjust the payout rate (= total payout amount / total sales amount) of the crane game machine 10.

Hereinafter, a description will be given with reference to the flowchart shown in FIG.
First, in the host device 6, a stress level threshold setting request is input by the administrator (step A1). In response to the threshold setting request, the stress level setting unit 6a presents, for example, a plurality of settable thresholds to the administrator through the display device. The administrator selects one of the presented threshold values at a plurality of stages and inputs a threshold setting instruction for the crane game machine 10 (step A2).

  In response to the threshold setting instruction, the stress level setting unit 6a transmits threshold setting data indicating the selected threshold to the crane game machine 10 and requests setting of the threshold of the stress level. (Step A3).

  On the other hand, when the control unit 30 of the crane game machine 10 receives the threshold setting data through the communication unit 36 (step B1), the threshold of the stress level by the catcher unit 14 based on the threshold setting data. Is set (step B2) (the threshold value is stored in the storage device 34).

  The stress level threshold value can be set at an arbitrary timing. When the crane game machine 10 executes a crane game in response to a request from the player, the crane game machine 10 moves downward in accordance with the latest threshold value stored in the storage device 34 at that time. Execute control.

  Here, the threshold of the stress level is set by the administrator in the host device 6, but the threshold of the stress level may be individually set in the crane game machine 10. In this case, a threshold value for detecting the pressing force by the catcher unit 14 can be designated using the joystick 20 and the button 21 provided in the crane game machine 10 or a dedicated input device (not shown). (Step B0). The control unit 30 sets a threshold value for the designated stress level (step B2).

  The host device 6 (or crane game machine 10) can instruct not only the stress level threshold but also the gripping force by the arm opening / closing mechanism 14a (grip strength adjusting mechanism 14a1) of the catcher unit 14. The control unit 30 controls the catcher driving unit 35 so that the arm 14b of the catcher unit 14 is closed with the instructed gripping force. By adjusting the gripping force of the catcher unit 14 in this way, the prizes piled up in the play field 11 can be easily gripped by the catcher unit 14 or conversely difficult to grip. For example, the payout rate is adjusted. Can do.

  By the way, the crane game machine 10 is in a state of waiting for coin insertion in the initial state. When the control unit 30 detects that a coin is inserted by the coin detection sensor 32, the control unit 30 starts the crane game (step B3).

  Here, when the joystick 20 is operated by the player, the control unit 30 moves the catcher unit 14 in the X and Y directions in accordance with the operation direction with respect to the joystick 20 and moves above the prizes stacked in the play field 11. (Step B4).

  When the button 21 is operated after the catcher unit 14 is moved above the prize, the control unit 30 starts to move the catcher unit 14 downward by the catcher up / down moving mechanism 40 (step B5). While the catcher unit 14 does not reach the prize or the floor surface of the play field 11, the tension arm 42 is maintained almost horizontal as shown in FIG. That is, it is determined that the pressure applied to the prize etc. by the catcher unit 14 has not reached a preset threshold value (No in Step B6). The control unit 30 continues the lowering of the catcher unit 14 by the catcher vertical movement mechanism 40 until the catcher unit 14 reaches a prize or the like (steps B5 and B6).

  Then, when the catcher unit 14 reaches the prize etc. and pushes down the prize etc. by its own weight, the tension arm 42 starts to rotate gradually as shown in FIG. The control unit 30 inputs data from the stress sensor 37 through the input unit 31, and has the stress level detected by the stress sensor 37 (pressing pressure by the catcher unit 14) reached a preset threshold value? Determine.

  For example, as shown in FIG. 5, when the stress sensor 37 includes a plurality of photocouplers 50a and 50b, a threshold value corresponding to the stress level when the rotation of the tension arm 42 is detected by the photocoupler 50b. Is set. When there is a change in the detection by the photocoupler 50b (when the light shielding plate 49 reaches between the light emitting unit and the light receiving unit of the photocoupler 50b), the control unit 30 sets the pressing pressure on the prize by the catcher unit 14 in advance. It determines with having reached the threshold value (step B6, Yes), and stops the downward movement of the catcher part 14 by the catcher up-and-down moving mechanism 40 (step B7).

  As shown in FIG. 6, when the stress sensor 37 is constituted by the rotor switch 51, the change in the stress level by the catcher unit 14 is detected in multiple stages as compared with the configuration using the photocouplers 50a and 50b. be able to. Therefore, the threshold value can be set more finely than when the configuration shown in FIG. 5 is used. When the amount of rotation of the tension arm 42 detected by the rotor switch 51 reaches a position corresponding to a preset threshold value, the control unit 30 sets the threshold pressure for the prize by the catcher unit 14 in advance. It is determined that the value has reached the value (step B6, Yes), and the downward movement of the catcher unit 14 by the catcher vertical movement mechanism 40 is stopped (step B7).

  Then, the control part 30 operates the arm opening / closing mechanism 14a through the catcher drive part 35, and closes the arm 14b of the catcher part 14 so that a prize may be grasped (step B8). Here, the arm 14b is closed by the control of the grip strength adjusting mechanism 14a1 so as to grip the prize with a grip force specified in advance.

  After the arm 14b of the catcher unit 14 is closed, the control unit 30 moves the catcher unit 14 upward (step B9), and further moves it in the XY direction to move it above the prize payout port 16 (step B10). . The control unit 30 opens the arm 14b of the catcher unit 14 when the catcher unit 14 moves the prize up above the prize payout port 16. At this time, if the prize is gripped by the catcher section 14 (arm 14 b), the gripped prize is dropped to the prize payout outlet 16 and reaches the prize takeout outlet 17 through the prize payout passage 18.

  Thus, in the first method, the lowering operation of the catcher unit 14 is stopped when the stress level (pressing pressure) detected by the stress sensor 37 reaches a threshold value set in advance by an administrator or the like. Therefore, the administrator can adjust the pressing by the catcher unit 14 on the prize etc. by setting an arbitrary threshold value. Further, it is possible to set an optimum threshold value for the weight of the catcher unit 14 at that time according to the weight of the weight 14g attached to the catcher unit 14.

  (2) A second method that is set by lottery during game execution.

  In this method, a lottery is performed mechanically every time a crane game is executed, and a threshold value of a stress level is set according to the lottery result. Therefore, since the pressing pressure applied to the prize etc. by the catcher unit 14 changes every time the crane game is executed, it is possible to give changes such as making the prize easy to grasp or difficult to grasp. it can.

Hereinafter, a description will be given with reference to the flowchart shown in FIG.
The crane game machine 10 is in a state of waiting for coin insertion in the initial state. When the control unit 30 detects that a coin has been inserted by the coin detection sensor 32, the control unit 30 starts a crane game (step C1).

  Before starting the process of moving the catcher unit 14, the control unit 30 obtains a threshold value of a stress level for a prize or the like of the catcher unit 14 by lottery (step C2). For example, as a lottery method, a random number value is generated by processing by a program, and a threshold value can be selected according to the random value. Alternatively, the data may be read out in a predetermined order from a data table in which irregularly different threshold data are arranged. In addition, a lottery can be carried out by any method.

  The control unit 30 sets the threshold value of the stress level by the catcher unit 14 based on the threshold value data obtained by lottery (step C3) (stores the threshold value in the storage device 34).

  Hereinafter, steps C4 to C10 shown in FIG. 9 are not described because they are the same as steps B4 to B10 in FIG.

  As described above, in the second method, every time the crane game is executed, the pressing pressure applied to the prize etc. by the catcher unit 14 is changed, so that the game is changed to improve the player's willingness to play. Can do. For example, depending on the type (size, shape, material, etc.) of the prizes piled up on the play field 11, it is easy to grip when the pressing force by the catcher unit 14 is large, or conversely, it is easy to grip when the pressing pressure is small. There is a case. The player starts the crane game in the hope that a lottery will be performed in which the prize is easily held by the catcher unit 14. In addition, when trying to use a strategy such as destroying a pile of prizes or rolling a prize to a prize payout exit, a lottery is performed so that the pressing force by the catcher unit 14 is larger than usual. It can also be expected to achieve the purpose effectively.

  (3) A third method for setting according to the game mode instructed by the player.

  In the crane game machine 10 using this method, it is assumed that the player can select one of the premium waste mode and the premium grip mode. The prize scrapping mode is an operation mode for executing a strategy such as breaking a pile of prizes so that it can be easily gripped by the catcher unit 14 or rolling the prize down to the prize payout exit 16. The prize grabbing mode is a catcher mode. This is a normal operation mode in which a prize is gripped by the unit 14.

Hereinafter, a description will be given with reference to the flowchart shown in FIG.
First, the player operates the button 21 to instruct which game mode to execute, the premium waste mode or the premium grab mode.

  When the execution of the premium waste mode is instructed (step D2, Yes), the control unit 30 sets the threshold value of the stress level by the catcher unit 14 to the preset first threshold value for the premium waste mode. (Step D3). For example, the first threshold value for the free gift waste mode is used when the purpose is to destroy the mountain of the free gift. Therefore, the first threshold value for the free gift grabbing mode to be described later is set. It is assumed that the pressure by the catcher unit 14 is set to a large value.

  Here, when the joystick 20 is operated by the player, the control unit 30 moves the catcher unit 14 in the X and Y directions in accordance with the operation direction with respect to the joystick 20 and moves above the prizes stacked in the play field 11. (Step D4).

  And the control part 30 operates the arm opening / closing mechanism 14a by the catcher drive part 35, and makes the arm 14b the state for premium waste modes (step D5). For example, when breaking a pile of prizes, if it is more effective that the arm 14b is in a closed state, the arm 14b is operated to close before the catcher unit 14 is lowered. It is also possible to adopt other forms for the free gift waste mode.

  When the button 21 is operated after the catcher unit 14 is moved above the prize, the control unit 30 starts to move the catcher unit 14 downward by the catcher up / down moving mechanism 40 (step D6).

  When the catcher unit 14 reaches the prize etc. and pushes down the prize etc. by its own weight, the tension arm 42 starts to rotate gradually as shown in FIG. The control unit 30 inputs data from the stress sensor 37 through the input unit 31, and whether the stress level detected by the stress sensor 37 (pressing pressure by the catcher unit 14) has reached a preset first threshold value. Is determined (step D7).

  Here, if it is determined that the stress level has reached the first threshold value (step D7, Yes), the control unit 30 stops the downward movement of the catcher unit 14 by the catcher vertical movement mechanism 40 (step B8). . And the control part 30 operates the arm opening / closing mechanism 14a by the catcher drive part 35, and makes the arm 14b the state for premium waste modes (step D9). For example, when the catcher unit 14 is lowered with the arm 14b closed, the arm 14b is operated to open while being pressed with a pressing pressure adjusted based on the first threshold value. As a result, it is possible to easily execute such things as breaking the prize mountain or moving the prize position.

  In the premium waste mode, not only the arm 14b but also a member used in the premium waste mode operation, for example, an extendable rod, is provided on the catcher unit 14, and this member is moved (stretched) to increase the prize mountain. It may be possible to break down.

  After the arm 14b of the catcher unit 14 is operated, the control unit 30 moves the catcher unit 14 to the initial position by the method for the premium waste mode (step D10).

  For example, the catcher unit 14 may be moved upward in the same manner as in the normal operation (premium grab mode) and then moved to the initial position by moving in the XY directions. Alternatively, the catcher unit 14 may be moved up in a predetermined distance and then moved up in the XY direction while the catcher unit 14 is lowered. In this case, by moving the catcher portion 14 in the XY directions, the piled prizes can be further broken, or the prizes can be dropped to the prize payout exit 16 by moving in the direction of the prize payout exit 16.

  The operation of the crane game in the free gift waste mode is thus completed. In this way, by breaking up the piled prizes, the prize is easily gripped by the catcher unit 14 when the crane game is subsequently executed in the prize-grab mode.

  When the execution of the premium grip mode is instructed (step D11, Yes), the control unit 30 sets the threshold value of the stress level by the catcher unit 14 to a preset second threshold value for the premium grip mode. (Step D12).

  Here, when the joystick 20 is operated by the player, the control unit 30 moves the catcher unit 14 in the X and Y directions in accordance with the operation direction with respect to the joystick 20 and moves above the prizes stacked in the play field 11. (Step D13).

  And the control part 30 operates the arm opening / closing mechanism 14a by the catcher drive part 35, and makes the arm 14b the state for premium grip mode (step D14). For example, the arm 14b is opened before the catcher unit 14 is lowered.

  When the button 21 is operated after the catcher unit 14 is moved above the prize, the control unit 30 starts to move the catcher unit 14 downward by the catcher up-and-down moving mechanism 40 (step D15).

  When the catcher unit 14 reaches the prize etc. and pushes down the prize etc. by its own weight, the tension arm 42 starts to rotate gradually as shown in FIG. The control unit 30 inputs data from the stress sensor 37 through the input unit 31, and whether the stress level detected by the stress sensor 37 (pressing pressure by the catcher unit 14) has reached a preset second threshold value. Is determined (step D16).

  Here, when it is determined that the stress level has reached the second threshold value (step D16, Yes), the control unit 30 stops the downward movement of the catcher unit 14 by the catcher vertical movement mechanism 40 (step D17). . And the control part 30 operates the arm opening / closing mechanism 14a by the catcher drive part 35, and closes the arm 14b so that a prize can be hold | gripped (step D18).

  After the arm 14b of the catcher unit 14 is operated, the control unit 30 moves the catcher unit 14 to the initial position by the method for the premium grip mode (step D19). That is, the control unit 30 moves the catcher unit 14 upward and then moves the catcher unit 14 to above the prize payout port 16 to open the arm 14b of the catcher unit 14. At this time, if the prize is gripped by the catcher section 14 (arm 14 b), the gripped prize is dropped to the prize payout outlet 16 and reaches the prize takeout outlet 17 through the prize payout passage 18.

  As described above, in the third method, the threshold of the stress level by the catcher unit 14 can be set according to each of the different game modes. Can be adjusted to an appropriate level.

  In the above-described third method, there is an example in which there are two game modes, the premium waste mode and the premium grab mode, but when there are three or more game modes, the game mode differs depending on each mode. Of course, it is also possible to set a threshold value.

  (4) A fourth method of setting according to the payout rate.

  In the crane game machine 10 using this method, a threshold value of a stress level is set in accordance with a payout rate that changes when a prize is paid out, and the payout rate can be adjusted by changing the pressing pressure by the catcher unit 14.

  For example, the crane game machine 10 executes the processes of steps B3 to B10 in the first method described above. As a result, when the prize gripped by the catcher unit 14 is dropped from the prize payout outlet 16, it is detected by the prize payout sensor 15 while passing through the prize payout passage 18 (step E1). When the prize payout sensor 15 detects the payout of the prize, the control unit 30 transmits the payout detection data to the host device 6 (step E2).

  On the other hand, the host device 6 receives the payout detection data from the crane game machine 10 (step F1), and calculates the payout rate (= total payout payout / total sales) (step F2). It is assumed that the host device 6 has also received data on the number of game executions from the crane game machine 10 (total sales = one game fee × number of executions). In addition, it is assumed that the unit price of the prize stored in the play field 11 of the crane game machine 10 (average price when plural kinds of prizes are mixed) is also stored in the storage device 34 in advance.

  When the calculated payout rate is within the preset setting range (No in Step F3), the control unit 30 assumes that the target payout rate is maintained, and stress according to the payout rate. Do not set (change) level thresholds.

  On the other hand, when the payout rate is not within the preset setting range (step F3, Yes), the control unit 30 determines a stress level threshold according to the payout rate (step F4). That is, when the payout rate exceeds the set range, the stress level threshold value is determined so as to weaken the pressure applied to the prize by the catcher unit 14, for example, in order to suppress the payout of the prize. Further, when the payout rate is below the set range, the stress level threshold value is determined so that, for example, the pressure applied to the prize by the catcher unit 14 is increased so that the prize is easily paid out.

  The stress level setting unit 6a of the host device 6 transmits threshold setting data indicating a threshold determined according to the payout rate to the crane game machine 10 (step F5).

  When the control unit 30 of the crane game machine 10 receives the threshold setting data through the communication unit 36 (step E3), the control unit 30 sets the stress level threshold by the catcher unit 14 based on the threshold setting data. (Step E4) (a threshold value is stored in the storage device 34).

  In the above description, the payout rate is calculated in the host device 6, but the payout rate may be calculated in the crane game machine 10 (control unit 30). In this case, the crane game machine 10 sets a threshold value of a stress level by the catcher unit 14 according to the payout rate in the own machine, and executes drive control for the catcher unit 14.

  In this way, by using the fourth method, it is possible to adjust the payout rate by changing the pressing pressure on the prize by the catcher unit 14.

  It should be noted that the first, second, and third methods described above may be implemented individually or in combination. For example, by combining the first and third methods, the first threshold value for the prize scrapping mode and the second threshold for the prize catching mode in each of the game modes (premium scrapping mode and prize grabbing mode), respectively. For example, the administrator can arbitrarily set the value. Furthermore, the fourth method can be combined. Also, by combining the second and third methods, the first threshold value and the second threshold value are set by lottery, and the pressure applied to the prize by the catcher unit 14 is changed every time the crane game is executed. It is also possible to improve the game performance. In addition, the fourth method can be performed in combination with the first or third method described above, for example.

  Further, the present invention is not limited to the above-described embodiments as they are, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. In addition, various inventions can be formed by appropriately combining a plurality of components disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, constituent elements over different embodiments may be appropriately combined.
