On the front surface of the game board 13, an outer rail 62 formed by bending a belt-shaped metal plate into a substantially arc shape is planted, and inside the outer rail 62, a belt-shaped metal plate similar to the outer rail 62. The arc-shaped inner rail 61 formed in step 1 is planted. The inner rail 61 and the outer rail 62 surround the outer periphery of the front surface of the game board 13, and the front and rear are surrounded by the game board 13 and the glass unit 16 (see FIG. 1), so that the front surface of the game board 13 has a ball. A game area in which a game is played is formed by the behavior of. The game area is an area formed by being partitioned by the two rails 61 and 62 on the front surface of the game board 13 and a resin outer edge member 73 that connects the rails (the winning opening and the like are arranged and fired). The area where the sphere flows down).

The two rails 61 and 62 are provided to guide the ball fired from the ball firing unit 112a (see FIG. 4) to the upper part of the game board 13. A return ball prevention member 68 is attached to the tip portion (upper left portion of FIG. 2) of the inner rail 61 to prevent a situation in which the ball guided to the upper part of the game board 13 returns to the ball guide passage again. To be done. At the tip of the outer rail 62 (upper right part in FIG. 2), a return rubber 69 is attached at a position corresponding to the maximum flight part of the ball, and the ball launched with a predetermined or more momentum hits the return rubber 69 to generate momentum. Is attenuated and bounces back toward the center.

The first symbol display device 37A, 37B provided with a plurality of LEDs, which are light emitting means, and a 7-segment display is disposed on the lower left side of the game area in front view (lower left side of FIG. 2). The first symbol display devices 37A and 37B are displays according to each control performed by the main control device 110 (see FIG. 4), and mainly display the gaming state of the pachinko machine 10. In the present embodiment, the first symbol display devices 37A and 37B are configured to be used properly depending on whether the ball has won the first winning opening 64 or the second winning opening 640. Specifically, when the ball wins the first winning opening 64, the first symbol display device 37A operates, while when the ball wins the second winning opening 640, the first The symbol display device 37B is configured to operate.

Further, the first symbol display device 37A, 37B, by the LED, indicates whether the pachinko machine 10 is in the process of positive change, time saving, or normal by the lighting state, or by indicating whether it is changing or not by the lighting state. , The stop symbol indicates whether it is a symbol corresponding to the probability variation jackpot, a symbol corresponding to the normal jackpot or a symbol that is out of sync with the lighting state, and the number of reserved balls is indicated by the lighting state, and the 7-segment display device gives a round during the jackpot. Display numbers and errors. In addition, the plurality of LEDs are configured such that the respective LEDs have different emission colors (for example, red, green, and blue), and the combination of the emission colors may suggest various gaming states of the pachinko machine 10 with a small number of LEDs. it can.

In the pachinko machine 10, a lottery is performed when the first winning opening 64 and the second winning opening 640 are won. In the lottery, the pachinko machine 10 determines whether or not it is a big hit (big hit lottery), and when it is a big hit, also makes a determination of the big hit type. As the types of jackpots determined here, 15R certainty jackpots, 4R certainty jackpots, and 15R regular jackpots are prepared. The first symbol display devices 37A, 37B not only show whether or not the result of the lottery is a big hit as a stop symbol after the end of variation, but if it is a big hit, a symbol according to the big hit type is shown. ..

Here, the "15R probability variation jackpot" is a probability variation jackpot in which the maximum round number shifts to a high probability state after the 15 rounds jackpot, and the "4R probability variation jackpot" is a jackpot with a maximum round number of 4 rounds. It is a certainty jackpot that shifts to a high probability state after. In addition, "15R regular jackpot" is a jackpot that shifts to a low-probability state after the jackpot with a maximum round number of 15 rounds and becomes a short-time state for a predetermined number of fluctuations (for example, 100 fluctuations). is there.

Also, the "high probability state" is a state in which the jackpot probability increases after the jackpot as an added value, that is, when the probability is changing (probably changing), in other words, a game that easily transitions to a special game state. Is the state of. The high-probability state (probably changing) in the present embodiment includes a state of a game in which the probability of hitting a second symbol, which will be described later, increases and the ball easily wins in the second winning opening 640. The "low probability state" refers to a state where the probability of big jackpot is not occurring, and the jackpot probability is normal, that is, a state where the jackpot probability is lower than that during the probability variation. In addition, the short-time state (in the time-shortening state) of the “low probability state” is a state in which the jackpot probability is a normal state, and the jackpot probability remains the same, and only the hit probability of the second symbol is increased to the second winning opening 640. It is a game state in which the ball is easy to win. On the other hand, when the pachinko machine 10 is normal, it is a state of the game which is neither probable change nor short time (a state in which neither the jackpot probability nor the hit probability of the second symbol is improved).

During the probability change or time saving, not only the probability of hitting the second symbol is increased, but also the time for which the electric accessory 640a associated with the second winning opening 640 is opened is changed, which is a long time compared to the normal time. Is set. When the electric accessory 640a is in an open state (open state), a ball is won in the second winning opening 640 as compared to when the electric accessory 640a is in a closed state (closed state). It will be in an easy state. Therefore, during the probability change or shortening of time, it becomes easy for the ball to win the second winning opening 640, and the number of times of the jackpot lottery can be increased.

It should be noted that, during the probability change or shortening of time, the opening time of the electric accessory 640a associated with the second winning opening 640 is not changed, or in addition to changing the opening time, the electric power is changed by one hit. The number of times that the accessory 640a is opened may be changed to be larger than that in the normal state. Also, during the probability change or shortening time, the winning probability of the second symbol is not changed, and the electric accessory 640a is opened at the time and once when the electric accessory 640a associated with the second winning opening 640 is opened. At least one of the numbers of times may be changed. In addition, during the probability change or shortening of time, the time when the electric accessory 640a associated with the second winning opening 640 is opened, or the number of times the electric accessory 640a is opened in one hit is not adjusted, and the second symbol is hit. Only the probability may be changed so as to be higher than that in the normal state.

In the game area, a plurality of general winning openings 63 are provided in which 5 to 15 balls are paid out as prize balls when the balls are won. A variable display device unit 80 is arranged in the center of the game area. The variable display device unit 80 is triggered by the winning (starting winning) to the first winning opening 64 and the second winning opening 640, while synchronizing with the variable display in the first symbol displaying devices 37A and 37B, It is composed of a third symbol display device 81 which is composed of a liquid crystal display (hereinafter simply referred to as "display device") which performs variable display, and an LED which variably displays the second symbol triggered by passage of a ball of the through gate 67. A second symbol display device (not shown) is provided.

Further, the variable display device unit 80 is provided with a center frame 86 so as to surround the outer periphery of the third symbol display device 81. The third symbol display device 81 is visible through an opening formed in the center of the center frame 86. Further, when the projecting operation unit 400 and the combined operation unit 500, which will be described later, are operated, at least a part of the relative displacement member 450 and the driven member 560 overhangs into the opening of the center frame 86 and is visible through the opening. It is said that. For example, when the protruding operation unit 400 is placed in the rotation position by the first operation (see FIG. 14A), the tip end portion of the relative displacement member 450 is visible through the opening of the center frame 86, When it is placed in the projecting position by the second motion (see FIG. 15B), substantially the entire relative displacement member 450 is visible through the opening of the center frame 86.

The third symbol display device 81 is composed of a large 9-inch liquid crystal display, and the display contents are controlled by the display control device 114 (see FIG. 4 ), for example, upper, middle and lower 3 Two symbol columns are displayed. Each symbol row is composed of a plurality of symbols (third symbol), these third symbols are horizontally scrolled for each symbol column, and the third symbol is variably displayed on the display screen of the third symbol display device 81. It is like this. In the third symbol display device 81 of the present embodiment, the display of the game state accompanied by the control of the main controller 110 (see FIG. 4) is performed on the first symbol display devices 37A and 37B, whereas the first The decorative display is performed according to the display of the symbol display devices 37A and 37B. Instead of the display device, for example, a reel or the like may be used to configure the third symbol display device 81.

The second symbol display device alternately turns on the symbol "o" and the symbol "x" as a display symbol (second symbol (not shown)) every time the ball passes through the through gate 67 for a predetermined time. It is a variable display. In the pachinko machine 10, when it is detected that the ball has passed through the through gate 67, a winning lottery is performed. As a result of the winning lottery, if it is a win, the symbol “◯” is stopped and displayed after the variable display of the second symbol on the second symbol display device. As a result of the winning lottery, if the result is off, the symbol “x” is stopped and displayed after the variable display of the second symbol on the second symbol display device.

In the pachinko machine 10, when the variable display on the second symbol display device is stopped by a predetermined symbol (in the present embodiment, a symbol "○"), the electric accessory 640a attached to the second winning opening 640 is for a predetermined time. It is configured to be activated (opened).

The time required for the variable display of the second symbol is set to be shorter during the probability change or during the time saving than when the game state is normal. As a result, during the probability change and the time reduction, the variable display of the second symbol is performed in a short time, so that the winning lottery can be performed more than usual. Therefore, the chances of winning in the winning lottery increase, so that the player can be given many opportunities to open the electric auditors product 640a of the second winning opening 640. Therefore, the ball can easily enter the second winning opening 640 during the probability change and the shortened working hours.

In addition, during the probability change or the shortening, the winning probability is increased, and the opening time of the electric accessory 640a per hit is increased or the number of times of opening is increased by other methods. When the ball is in a state of easy winning, the time required for variable display of the second symbol may be constant regardless of the gaming state. On the other hand, when the time required for the variable display of the second symbol is set to be shorter than the normal time during the probability change or the shortened time, the hit probability may be constant regardless of the gaming state, or one hit. The opening time and the number of times of opening the electric accessory 640a may be constant regardless of the game state.

The through gate 67 is attached to the game board on the right side in the lower region of the variable display device unit 80, and among the balls emitted to the game board, a part of the ball flowing down on the right side of the game board can pass through. Is configured. When the ball passes through the through gate 67, a winning lottery for the second symbol is performed. After the winning lottery, a variable display is performed on the second symbol display device, and if the result of the winning lottery is a win, the symbol "○" is displayed as a stop symbol of the variable display, and the result of the winning lottery is out. For example, the symbol "x" is displayed as the variable display stop symbol.

The number of times the ball passes through the through gate 67 is held up to a maximum of four times in total, and the number of holding balls is displayed by the above-mentioned first symbol display devices 37A, 37B and at the second symbol holding lamp (not shown). Is also lit. Four second design holding lamps are provided for the maximum number of holdings, and are symmetrically arranged below the third design display device 81.

The variable display of the second symbol is performed by switching the lighting and non-lighting of a plurality of lamps in the second symbol display device as in the present embodiment, as well as the first symbol display devices 37A, 37B and the third. It may be performed by using a part of the symbol display device 81. Similarly, the second symbol holding lamp may be turned on by a part of the third symbol display device 81. Further, the maximum number of retained balls for the passage of the ball through the through gate 67 is not limited to four times, and may be set to three times or less, or five times or more (e.g., eight times). Further, the number of through gates 67 to be assembled is not limited to one, but may be plural (for example, two). Further, the mounting position of the through gate 67 is not limited to the right side of the variable display device unit 80, and may be, for example, the left side of the variable display device unit 80. Further, since the number of reserved balls is indicated by the first symbol display devices 37A and 37B, it is possible not to perform lighting display by the second symbol reservation lamp.

Below the variable display device unit 80, a first winning opening 64 through which a ball can be won is arranged. When a ball wins the first winning opening 64, a first winning opening switch (not shown) provided on the back side of the game board 13 is turned on, and the main controller 110 is caused by the turning on of the first winning opening switch. (Refer to FIG. 4) A big hit lottery is made, and a display corresponding to the lottery result is shown on the first symbol display device 37A.

On the other hand, below the first winning opening 64 in a front view, a second winning opening 640 in which a ball can win is arranged. When a ball wins the second winning opening 640, a second winning opening switch (not shown) provided on the back side of the game board 13 is turned on, and the main controller 110 is caused by the turning on of the second winning opening switch. (Refer to FIG. 4) A big hit lottery is made, and a display corresponding to the lottery result is shown on the first symbol display device 37B.

In addition, each of the first winning opening 64 and the second winning opening 640 is also one of the winning openings through which five balls are paid out as winning balls when a ball wins. In addition, in the present embodiment, the number of prize balls paid out when the balls enter the first winning opening 64 and the number of prize balls paid out when the balls enter the second winning opening 640 are the same. , The number of prize balls paid out when a ball is won in the first winning opening 64 and the number of prize balls paid out when a ball is winning in the second winning opening 640, for example, a ball to the first winning opening 64 The number of prize balls to be paid out when a prize is won may be set to 3, and the number of prize balls to be paid out when a ball is won to the second winning port 640 may be set to 5.

An electric accessory 640a is attached to the second winning opening 640. The electric accessory 640a is configured to be openable and closable, and normally, the electric accessory 640a is in a closed state (reduced state), which makes it difficult for a ball to enter the second winning opening 640. On the other hand, as a result of the variable display of the second symbol that is performed upon the passage of the ball to the through gate 67, when the symbol "○" is displayed on the second symbol display device, the electric accessory 640a is in the open state (enlarged). State), and the ball is in a state where it is easy to enter the second winning opening 640.

As described above, the probability of hitting the second symbol is higher than that in the normal state during the probability change and the shortening of the time, and the time required for the variable display of the second symbol is also short, so in the variable display of the second symbol, “○” is displayed. Is easily displayed, and the number of times the electric accessory 640a is in the open state (enlarged state) increases. Furthermore, the time during which the electric accessory 640a is opened during the probability change and the shortening of time is longer than that during the normal time. Therefore, during the probability change and the shortened working hours, it is possible to create a state in which the ball is more likely to win the second winning opening 640 than in the normal time.

Here, the probability of a jackpot is the same in the case where the ball wins the first winning opening 64 and the case where the ball wins the second winning opening 640 in the low probability state and the high probability state. However, when the jackpot is a big hit, the probability that the 15R probability variation jackpot is selected as a jackpot type is higher when the ball is won at the second winning port 640 than when the ball is won at the first winning port 64. It is set. On the other hand, the first winning opening 64 does not have an electric accessory like the second winning opening 640, and the ball is always ready for winning.

Therefore, during normal operation, the electric winning object attached to the second winning opening 640 is often in a closed state, and it is difficult to win the second winning opening 640. Then, the ball is fired so that the ball passes the left side of the variable display device unit 80 (so-called "left hitting"), and a lot of chances of the big hit lottery are obtained by winning the prize at the first winning a prize port 64, which is a big hit. It is advantageous for the player to aim for that.

On the other hand, during the probability change or shortening of time, by passing the ball through the through gate 67, the electric accessory 640a associated with the second winning port 640 is likely to be opened, and the second winning port 640 is easily won. Therefore, the ball is fired toward the second winning port 640 so that the ball passes the right side of the variable display device 80 (so-called “right hit”), and the electric accessory is opened by passing through the through gate 67. At the same time, it is more advantageous for the player to aim for the 15R certainty variation jackpot by winning the second winning opening 640.

In this way, the pachinko machine 10 of the present embodiment shoots a ball at the player according to the gaming state of the pachinko machine 10 (whether it is in a sudden change, during a shortening time, or during a normal time). Can be changed to "left-handed" and "right-handed". Therefore, the player can be changed in how to hit the ball, and the game can be enjoyed.

The ring-shaped divided bodies 440L1 to 440R2 are formed in a shape obtained by dividing the ring-shaped shape into four in the circumferential direction, and when these ring-shaped divided bodies 440L1 to 440R2 are displaced to the central position, the divided surfaces contact each other. Then, an annular shape is formed (see FIG. 41).

The decorative cover 500 is attached to the standing end surface of the outer wall portion 212 of the rear case 210, and is arranged on the front (front) side of the ring forming unit 400. That is, the decorative cover 500 is partially covered only on the portion along the outer wall portion 212 of the rear case 210 to shield the vertical slide unit 300 and the ring forming unit 400 from the player, while the opening 211a (that is, the first cover). The 3 symbol display device 81) is exposed so that it can be visually recognized by the player.

The detailed configurations of the vertical slide unit 300 and the ring forming unit 400 of the operation unit 200 configured as above will be described below. First, the detailed configuration of the vertical slide unit 300 will be described with reference to FIGS. 7 to 28.

It is a figure.

As shown in FIGS. 7 to 10, in the vertical slide unit 300, the first racks 315 are arranged on one side and the other side in the longitudinal direction of the displacement member 310 in a posture parallel to each other. The rack 315 meshes with each first pinion 351 arranged on each of the one-side member 320L and the other-side member 320R. Further, the displacement member 310 is slidably connected to the guide rod P on one side and the other side in the longitudinal direction, and in the assembled state, the guide rod P has the axial direction of the one side member 320L and the other side member 320R. It is arranged (fixed) on the one-side member 320L and the other-side member 320R in a posture matched with the longitudinal direction.

Therefore, in the vertical slide unit 300, when the first pinion 351 is rotated by the driving force of the drive motor 341 and the first rack 315 is linearly moved by the rotation, the displacement member 310 is guided by the linear motion. While being guided by the rod P, the one side member 320L and the other side member 320R are displaced along the longitudinal direction (see FIG. 21). Here, a detailed configuration of the displacement member 310 will be described with reference to FIGS. 11 to 14.

11A is a front view of the displacement member 310, and FIG. 11B is a rear view of the displacement member 310. 12A is a partially enlarged cross-sectional view of the displacement member 310 taken along line XIIa-XIIa in FIG. 11B, and FIG. 12B is a displacement member 310 taken along line XIIb-XIIb in FIG. 11B. FIG. 13 is an exploded front perspective view of the displacement member 310 when the disassembled displacement member 310 is viewed from the front, and FIG. 14 is an exploded rear perspective view of the displaced member 310 when the disassembled displacement member 310 is viewed from the rear side.

As shown in FIGS. 11 to 14, the displacement member 310 includes a main body portion 311 formed in a long shape of a horizontally long rectangle in a front view, and a cylinder protruding toward the front at the center of the main body portion 311 in the longitudinal direction. -Shaped rotary base 312, a rotary body 313 that is rotatably and concentrically supported by the rotary base 312 and has a circular shape in a front view, and an end side that is displaceably coupled to one side and the other side in the longitudinal direction of the main body 311. It mainly includes a portion 314 and a first rack 315 that is fastened and fixed to the back surface of the end portion 314.

The body portion 311 is provided with a pair of upper and lower projecting pins 311 a projecting from the back surface on one side and the other side in the longitudinal direction, respectively. The projecting pin 311 a is a portion for connecting the end side portion 314 to the main body portion 311 in a displaceable manner, is formed in a cylindrical shape having a circular cross section, and is inserted into the elongated hole 314 a of the end side portion 314.

The pair of upper and lower projecting pins 311a are arranged along a direction orthogonal to the longitudinal direction of the main body portion 311 (vertical direction in FIG. 11B), and the longitudinal direction of the projecting pin 311a on one side of the longitudinal direction of the main body portion 311 is different from that of the projecting pin 311a. The projecting pin 311a on the other side is arranged along the longitudinal direction of the body portion 311 (the left-right direction in FIG. 11B).

In addition, stopper surfaces 311b are formed on the end surfaces (the left side surface and the right side surface in FIG. 11A) on one side and the other side in the longitudinal direction of the main body section 311. The stopper surface 311b is a portion for restricting the relative displacement between the body portion 311 and the end side portion 314 within a prescribed range, and is formed as a flat surface perpendicular to the longitudinal direction of the body portion 311.

A drive motor and a gear mechanism (both not shown) are provided inside the rotation base 312, and the rotation driving force of the drive motor is transmitted to the rotation body 313 by the gear mechanism, whereby the rotation body 313 rotates. It is rotated relative to the base 312 (main body 311). The rotation base 312 is fixed to the main body 311. Therefore, as described later, the rotation base 312 is held by another member, so that the displacement of the main body portion 311 with respect to the end side portion 314 can be restricted (see, for example, FIG. 65 ).

An elongated hole 314a, a stopper surface 314b, and a slider holding portion 314c are formed in the end side portion 314. The oblong holes 314a are a pair of upper and lower through holes for receiving the protruding pins 311a of the main body portion 311 and are formed as oblong holes when viewed from the front. The oblong hole 314a is a direction orthogonal to the direction in which the end portion 314 slides along the guide rod P in the major axis direction of the oblong shape (that is, the longitudinal direction of the displacement member 310 and the one side member 320L). 11B and the other side member 320R are connected to each other, that is, the horizontal direction in FIG. 11B).

In this case, between the projecting pin 311a of the main body portion 311 and the elongated hole 314a of the end side portion 314, a cylindrical tubular portion and a flange protruding radially outward from the outer peripheral surface of the tubular portion. A color C, which is composed of parts, is provided. In the collar C, the inner diameter of the tubular portion is set to be equal to or slightly larger than the outer diameter of the protruding pin 311a of the main body portion 311, and the outer diameter of the tubular portion is equal to the short diameter of the long hole 314a of the end side portion 314 or The outer diameter of the flange portion is set to be slightly smaller than that of the elongated hole 314a of the end side portion 314 (see FIG. 12).

Thereby, as will be described later, the projecting pin 311a of the main body portion 311 passes through the collar C in the long hole 314a of the end side portion 314 in the long diameter direction of the long hole 314a (left and right direction in FIG. 12A). It is possible to displace along. That is, the body portion 311 can be displaced relative to the end portion 314 (see FIG. 27). Since the collar C rolls between the projecting pin 311a and the elongated hole 314a by interposing the collar C in this manner, relative displacement can be smoothly performed and wear can be suppressed. The durability can be improved.

The stopper surface 314b is a portion for restricting the relative displacement between the main body portion 311 and the end side portion 314 within a prescribed range, is formed as a flat surface, and is in an assembled state (the main body portion 311 and the end side). It is formed at a position facing the stopper surface 311b of the main body portion 311 at a predetermined interval in the state where the portion 314 is connected).

The stopper surfaces 311b and 314b of the main body portion 311 and the end side portion 314 are arranged in the case where the projecting pins 311a of the main body portion 311 are located at the centers of the long holes 314a of the end side portion 314 in the major axis direction (that is, 11(a), when the main body 311 is in a parallel posture with respect to the left and right end side portions 314, the main body 311 faces each other in a parallel posture.

Further, while maintaining this parallel posture, each protruding pin 311a (color C) is located at the end of one side (the left side in FIG. 11A) in the major axis direction of each elongated hole 314a or the other side in the major axis direction (FIG. 11(a)). ) On the right side), the stopper surfaces 311b and 314b are opposed to each other at a predetermined interval on both the one side and the other side in the longitudinal direction of the main body 311 (between the stopper surfaces 311b and 314b). Gap is formed in).

A rack portion 315a and a slider holding portion 315c are formed on the first rack 315. The rack portion 315a is a rack formed by cutting a side surface of a flat plate-shaped member and meshed with the first pinion 351 (see FIG. 9) of the one-side member 320L and the other-side member 320R. In the assembled state, the tooth surface is arranged in a posture parallel to the axis of the guide rod P.

The slider holding part 315c is a part for holding the slider S between the slider holding part 314c of the end side part 314. The slider holding portion 314c of the end side portion 314 and the slider holding portion 314c of the first rack 315 are each formed in a vertically divided shape of a cylinder, and are in an assembled state (the first rack is fastened and fixed to the end side portion 314). (State), the slider S is held between the opposing surfaces (between the inner peripheral surfaces of the cylinder).

The slider S is a cylindrical member that is fitted onto the guide rod P and slides along the axial direction of the guide rod P, and the outer diameter of the slider S corresponds to the inner diameters of the slider holding portions 314c and 315c. Is set. A pair of upper and lower engaging walls project inward from the inner peripheral surfaces of the slider holding portions 314c and 315c. In the assembled state, the pair of upper and lower engaging walls are on the axial end surfaces of the slider S. It abuts and prevents the slider S from coming off in the axial direction.

In this way, by adopting the structure in which the slider S is provided between the end side portion 314 and the first rack 315 and the guide rod P, the slider S is slidable with respect to the brass guide rod P. While it can be formed from a material having excellent wear resistance, the material of the end side portion 314 and the first rack 315 can be set independently of the brass guide rod P. That is, since the end portion 314 is a member that regulates the relative displacement of the main body portion 311 by the stopper surface 314c, it is effective to be able to select a material that can ensure rigidity during the regulation. On the other hand, the first rack 315 is a member that is meshed with the first pinion 351 and is linearly moved by receiving the rotational driving force thereof. Therefore, it is effective to select a material that can ensure rigidity for maintaining the meshed state. Becomes

It returns to FIG. 7 to FIG. 10 and demonstrates. As described above, the vertical slide unit 300 is arranged on one side and the other side in the longitudinal direction of the displacement member 310 by rotating the first pinions 351 arranged on the one side member 320L and the other side member 320R, respectively. The first racks 315 provided are linearly moved, respectively, whereby the displacement member 310 is guided by the guide rods P fixed to the one side member 320L and the other side member 320R, and is slid vertically. To be done. Here, detailed configurations of the one side member 320L and the other side member 320R will be described with reference to FIGS. 15 to 20.

FIG. 15 is an exploded front perspective view of the vertical slide unit 300 when the exploded vertical slide unit 300 is viewed from the front, and FIG. 16 is an exploded rear perspective view of the vertical slide unit 300 when the exploded vertical slide unit 300 is viewed from the rear. is there.

The one-side member 320L and the other-side member 320R have a slight difference in shape, but with respect to a portion exhibiting a technical function, left-right symmetry (a plane symmetry with respect to an imaginary plane located in the center between the two members facing each other). Since the other side member 320R is described as a representative example, the description of the one side member 320L will be omitted.

As shown in FIGS. 15 and 16, the other-side member 320R includes a rear surface base 331, an intermediate base 332 provided on the front surface (front surface) side of the rear surface base 331, and a front surface (front surface) of the intermediate base 332. The front base 333 provided on the side, the drive motor 341 attached to the intermediate base 332, the first pinion 351 rotated by the driving force of the drive motor 334, and the drive motor 334 to the first pinion 351. And a transmission mechanism for transmitting the driving force of. Here, detailed configurations of the back base 331, the intermediate base 332, and the front base 333 will be described with reference to FIGS. 17 and 18.

FIG. 17 is a front perspective view of the rear base 331, intermediate base 332, and front base 333, and FIG. 18 is a rear perspective view of the rear base 331, intermediate base 332, and front base 333.

As shown in FIGS. 17 and 18, the rear surface base 331 has a substantially L-shape in a front view from a vertically long body portion and a protruding portion laterally protruding from a lower end of the body portion. A transmission mechanism (see FIGS. 15 and 16) that is formed and transmits the driving force of the drive motor 341 to the first pinion is housed between the intermediate base member 332.

The rear base 331 is provided with a pinion shaft 331a and a rack shaft 331b projecting from the front surface of the main body portion (a surface facing the intermediate base 332), and the first opening 331c and the second opening are provided in the main body portion and the protruding portion. The openings 331d are formed.

The pinion shaft 331a is a shaft-shaped body having a circular cross section for rotatably supporting the first pinion 351 (see FIG. 19), and the rack shaft 331b is a guide groove 364a of the second rack 364 (see FIG. 19). It is a shaft-shaped body having a circular cross section for being inserted into the second rack 364 to regulate the posture of the second rack 364. A screw is fastened to the end surface of the pinion shaft 331a, and the head of the screw serves as a retainer for the first pinion 351. Further, the diameter of the rack shaft 331b is set to be equal to or slightly smaller than the groove width of the guide groove 364a of the second rack 364, and the second rack 364 is rotatable about the rack shaft 331b.

The rack shaft 331b is arranged at a position facing the gear shaft 332i of the intermediate base 332 in the assembled state of the back surface base 331 and the intermediate base 332. In detail, the arrangement position of the rack shaft 331b is set such that the direction connecting the shaft center of the rack shaft 331b and the shaft center of the gear shaft 332i is orthogonal to the linear movement direction of the second rack 364. .. Thereby, as will be described later, the second rack 364 whose guide groove 364a is guided by the rack shaft 331b can be displaced along the tooth surface of the second pinion 365a pivotally supported by the gear shaft 332i ( See FIG. 26).

Each of the first opening 331c and the second opening 331d is an opening extending linearly, and is a region (biased in a front view) corresponding to the biasing spring 366 (see FIG. 22) arranged in a bent posture. It is formed in a region overlapping the spring 366). Therefore, when the urging spring 366 is mounted, after the urging spring 366 is housed between the back surface base 331 and the intermediate base 332, the urging spring 366 is inserted through the first opening 331c or the second opening 331d. Since the work of locking the end portion to the mating member can be performed, the biasing spring 366 can be mounted in a bent posture while being restrained from being repelled (jumping by the elastic recovery force of itself). The mounting work of the biasing spring 366 will be described later (see FIG. 28).

Since the biasing spring 366 is a coil spring and the outer peripheral surface is curved in an arc shape, the opening width of the first opening 331c and the second opening 331d should be smaller than the diameter of the biasing spring 366. Is preferred. This is because the lowering of the rigidity of the back surface base 331 can be suppressed while enabling the locking of the end portion and the suppression of the sliding resistance.

The intermediate base 332 is formed in a shape corresponding to the back base 331. That is, the intermediate base 332 is formed in a substantially L shape in a front view from a vertically long body portion and a protruding portion that laterally extends from the lower end of the body portion. By being provided on the front (front) side, the transmission mechanism is housed in the space formed between the two facing each other.

A first pinion insertion window 332a and a motor shaft insertion window 332b are formed in the main body portion of the intermediate base 332, and a plurality of gear shafts 332c to 332i are formed from the rear surface of the main body portion (a surface facing the rear base 331). A roller shaft 332r is provided so as to project. The first pinion insertion window 332a is an opening for exposing the first pinion 351 pivotally supported by the pinion shaft 331a of the back base 331 to the front (front) side of the intermediate base 332, and thus the first pinion 351 can be meshed with the first rack 315 of the displacement member 310 (see FIG. 21).

The motor shaft insertion window 332b connects the drive shaft of the drive motor 341 attached to the front surface (front surface) of the intermediate base 332 to the gear 361 of the transmission mechanism housed between the rear base 331 and the intermediate base 332 facing each other. It is an opening for. The plurality of gear shafts 332c to 332i are shaft-shaped bodies having circular cross sections for rotatably supporting the gears 362a to 362e, the crank gear 363, and the transmission gear 365 of the transmission mechanism. Screws are fastened to the end surfaces of the gear shafts 332c to 332i, and the heads of the screws serve as retainers for the gears 362a to 362e, the crank gear 363, and the transmission gear 365 of the transmission mechanism.

The roller shaft 332r is a cylindrical body having a circular cross section for rotatably supporting the roller 367 (see FIG. 19) of the transmission mechanism. The roller 367 pivotally supported by the roller shaft 332r is held by the facing surfaces of the back base 331 and the intermediate base 332 (the facing surfaces are retained).

The intermediate base 332 has a pair of left and right restricting walls 332t projecting from the back surface of the body portion (a surface facing the back surface base 331) and the front surface of the body portion (a surface facing the front base 333). A pair of upper and lower holding recesses 332j and 332k are formed, and a connecting shaft 332m is projectingly provided on the front surface (a surface facing the front base 333) of the protruding portion.

The restriction wall 332t is a part for restricting the posture of the second rack 364, and a pair is formed with a predetermined interval. The facing distance between the pair of restriction walls 332t is larger than the width dimension of the second rack 364, and is formed so as to have a clearance between the side surface of the second rack 364. Therefore, the second rack 364 can be rotated about the rack shaft 331b by the amount of the gap (see FIG. 26).

The holding recesses 332j and 332k are portions for holding the upper end side and the lower end side of the guide rod P, respectively, and are separated from each other in the vertical direction (the vertical direction in FIG. 17) by a distance equivalent to the length dimension of the guide rod P. It is formed as a recess that is located and is open on the front base 333 side. The depth and width of the recess are set to be equal to or slightly larger than the diameter of the guide rod P. Therefore, by fitting the guide rod P into the holding recesses 332j and 332k and covering (fastening and fixing) the front base 333 to the intermediate base 332, the guide rods are provided between the back surface of the front base 333 and the holding recesses 332j and 332k. The guide rod P can be firmly held by sandwiching P.

Thereby, the other side member 320R is assembled in a state excluding the front base 333, the guide rod P is held by the displacement member 310, and the guide rod P held by the displacement member 310 is fitted into the holding recesses 332j, 332k. By mounting (fastening and fixing) the front base 333, the other side member 320R and the displacement member 310 can be connected. Therefore, the assembling work of the vertical slide unit 300 can be made efficient.

The connecting shaft 332m is a shaft-shaped body having a circular cross section that serves as a connecting portion with the interposing member 370, and is rotatably inserted into the connecting hole in the connecting plate 371 of the interposing member 370, so that the other side member 320R is connected. The interposition member 370 is connected. That is, the other-side member 320R and the interposition member 370 are connected in a state in which the relative position can be adjusted. Accordingly, as will be described later, when the vertical slide unit 300 is attached to the rear case 210, the attachment work can be performed while adjusting the attachment position, so that the workability can be improved.

Next, with reference to FIG. 19, detailed configurations of the transmission mechanism and the first pinion 351 will be described. 19A is a front perspective view of the transmission mechanism in a front view of the transmission mechanism in the assembled state, and FIG. 19B is a rear perspective view of the transmission mechanism in a rear view of the transmission mechanism in the assembled state.

Gears 362a to 362e as a gear train, a crank gear 363 meshed with a rear gear 362e of the gear train, a second rack 364 driven by a crank mechanism of the crank gear 363, and a second rack 364 thereof. A transmission gear 365 meshed with each other, an urging spring 366 for applying an urging force to the second rack 364, and a roller 367 for keeping the urging spring 366 in a bent posture. ..

Here, detailed configurations of the crank gear 363 and the second rack 364 will be described with reference to FIG. 20A is a front perspective view of the crank gear 363 and the second rack 364 in the disassembled state, and FIG. 20B is a rear perspective view of the crank gear 363 and the second rack 364 in the disassembled state.

As shown in FIGS. 20(a) and 20(b), the crank gear 363 is provided with an eccentric pin 363a at a position eccentric from the center of rotation and a side on which the eccentric pin 363a is provided. A detected portion 363b is provided so as to project from the opposite side. The eccentric pin 363a is formed in a cylindrical shape having a circular cross section, and is inserted into the rack groove 364b of the second rack 364 in the assembled state. The detected part 363b is a part detected by a sensor device (not shown), and the sensor device detects the detected position of the detected part 363b by the detection part and the rotational position (phase) of the crank gear 363 is detected. ) Is detected. Based on this detection result, main controller 110 can be made aware that displacement member 310 has been placed in the raised position (see FIG. 21A) or the lowered position (see FIG. 21C).

A guide groove 364a and a rack groove 364b are formed in the second rack 364. The guide groove 364a is an opening through which the rack shaft 331b (see FIG. 17) of the rear base 331 is inserted, and is linear in a direction parallel to the tooth surface of the rack (vertical direction in FIG. 20A and FIG. 20B). Is extended in a shape.

The rack groove 364b is a concave groove into which the eccentric pin 363a of the crank gear 363 is inserted, and is linearly extended in a direction perpendicular to the tooth surface of the rack. The groove width of the rack groove 364b is set to be equal to or slightly larger than the diameter of the eccentric pin 363a, and the eccentric pin 363a can slide along the rack groove 364b as the crank gear 363 rotates. ..

The rack groove 364b is linearly extended in a direction perpendicular to the tooth surface of the rack (that is, a direction orthogonal to the linear movement direction of the second rack 364), so that the eccentric pin of the crank gear 363 will be described later. It is possible to suppress the generation of a component other than the linear movement direction of the second rack 364 in the force component that acts on the rack groove 364b of the second rack 364 from 363a, and correspondingly, the resistance when the second rack 364 linearly moves. Can be suppressed.

It returns to FIG. 19(a) and FIG. 19(b), and demonstrates. The transmission gear 365 includes a second pinion 365a meshed with the rack of the second rack 364 and a speed increasing portion 365b meshed with the first pinion 351. The second pinion 365a and the speed increasing portion 365b are connected to each other. They are integrally formed in a concentric state.

The biasing spring 366 is a coil spring made of metal, and has one end locked to the lower end of the second rack 364 and the other end locked to the end of the projecting portion of the intermediate base 332. The biasing spring 366 is elastically stretched and deformed when the second rack 364 is located at the lower end of the movable range, and applies the elastic recovery force to the second rack 364 as a biasing force. When the second rack 364 is displaced from the lower end to the upper end of the movable range, the second rack 364 is further deformed in tension with the displacement, so that the biasing force applied to the second rack is gradually increased and the second rack 364 moves. When it reaches the upper end of the range, it is in the most tensilely deformed state, and applies the maximum biasing force to the second rack 364.

As will be described later, the biasing spring 36
