Description

  The present invention relates to an apparatus and a method for forming a drawn food in which a drawn pattern is formed on the surface of a food material.

  2. Description of the Related Art Various types of drawn foods represented by tea width drawing have been provided. A tea-brush squeezer is made by steaming or boiling ingredients such as azuki bean, sweet potato, yurine, and chestnut, then grinding and processing into a bowl-like shape, wrapping with a tea-bread (or rag) such as linen, etc. Is.

The process of forming the ingredients with such a tea width drawing is handmade one by one, which is time consuming and causes problems in that the finish tends to vary and the production efficiency is poor. In Patent Document 1, an attempt has been made to mechanize the formation of food by tea width drawing, and a rod-shaped food is guided into the surrounding film, and a plurality of shutter bodies are driven to expand and contract the forming and cutting region, thereby enclosing the surrounding film. The point of cutting the stick food is described. Japanese Patent Application Laid-Open No. H10-228561 describes that the outer sheet material and the central material are arranged in the center of the shutter sheet, wrapped with the shutter sheet, and the shutter sheet is drawn by twisting with a rotating means.
Japanese Patent No. 2537751 Japanese Utility Model Publication No. 60-10477

  According to the molding method described in Patent Document 1, a drawn pattern is formed by a surrounding film on the surface of the cut food material, but it is difficult to form a deeply squeezed drawn pattern like a hand-drawn brown bread drawn. Met. In other words, in the case of handmade, the food is wrapped and squeezed with a tea cloth, but in Patent Document 1, the food is not wrapped with a surrounding film, but only cut through the surrounding film, so only on the top of the top surface. Although a concavo-convex pattern is formed, a deeply carved drawing pattern cannot be formed on the entire surface like handmade.

  Further, in Patent Document 2, food is wrapped and twisted by a shutter sheet as in the case of handmade, but in the case of a sticky food, it cannot be easily separated from the shutter sheet, and the shape collapses when taken out. There is a case.

  In order to solve such problems, the present inventors have proposed a novel drawing-molded food molding apparatus (see Japanese Patent Application No. 2006-284371). Using such a new molding device, it has become possible to stably mass-produce foods with deeply squeezed drawn patterns, but drawn foods typified by tea-drawn drawing are drawn using a single ingredient. Therefore, it was a food with little variation. In the novel molding apparatus described above, it has become possible to mold a novel molded food such as a tea draw drawn using a plurality of ingredients, but the appearance is the same as the conventional one.

  Accordingly, the present invention provides a molding apparatus and method capable of efficiently forming a variety of drawn foods in which a deeply drawn pattern similar to handmade is formed on the entire surface and a plurality of ingredients are combined. It is for the purpose.

  An apparatus for forming a drawn food according to the present invention includes an outer nozzle means for discharging a first food, an inner nozzle means for discharging a second food disposed inside the outer nozzle means, and the inner nozzle means for the outer nozzle means. The first food material is cylindrical by a predetermined length so as to cover the periphery of the second food material continuously discharged from the inner nozzle means by reciprocating between the closed position and the open position of the opening of the nozzle means. A rod-shaped forming means for intermittently forming, a stretchable sheet body disposed so as to surround a passage region of the rod-shaped food, and a portion of the rod-shaped food that is not covered with the first food And drawing forming means for cutting the sheet by drawing with the sheet member. Further, the drawing means includes a first drawing means including a plurality of drawing members arranged so as to surround the sheet body, and a plurality of drawing members arranged so as to surround the sheet body. The second diaphragm means disposed above the first diaphragm means at a predetermined interval, and the passage member is closed by operating the diaphragm member of the first diaphragm means to squeeze the sheet body. And a throttle control means for operating the throttle member of the second squeezing means to cut the portion that is not covered with the first food material by squeezing with the sheet body. To do. Furthermore, a support member that supports the cut food material and a support control device that moves the support member up and down so as to contact the bottom surface of the cut food material are provided below the first squeezing device. It is characterized by being.

  In the method for forming a drawn food according to the present invention, an inner nozzle means for discharging the second food material is disposed inside the outer nozzle means for discharging the first food material, and the inner nozzle means is closed with the opening of the outer nozzle means. The first food is intermittently formed into a cylindrical shape by a predetermined length so as to cover the periphery of the second food continuously discharged from the inner nozzle means by reciprocating between the position and the open position. Supplying the molded food material to the inside of a stretchable sheet body disposed so as to surround the passage area, and closing the passage area by squeezing the sheet body, then the rod-shaped food material It cut | disconnects by restrict | squeezing the part which is not coat | covered with a 1st foodstuff with the said sheet | seat body.

  The present invention has the above-described configuration, so that the first food material is intermittently formed into a cylindrical shape by a predetermined length so as to cover the periphery of the second food material continuously discharged from the inner nozzle means. A portion of the rod-shaped food that is not covered with the first food is cut by squeezing with the sheet using a stretchable sheet that is disposed so as to surround the passage region of the prepared food. Therefore, it can be molded in a state where the periphery of the second food is partially covered by the first food. For example, if different colors are combined as the first food and the second food, compared to the conventional food This makes it possible to mold drawn foods that are rich in variations. As shown in FIG. 13, if the second food material is exposed on the upper part of the molded product and the other lower portion is formed so as to be covered with the first food material, it can be finished into a squeezed food with a floral pattern. it can.

  Also, the passage area is closed by squeezing the extendable sheet body with the first squeezing means, and the food material is cut by squeezing the sheet body with the second squeezing means disposed above the first squeezing means. The cut food is squeezed in a state of being wrapped by the sheet body between the first squeezing means and the second squeezing means, and the squeezed deeply carved on the entire upper surface, lower surface and side surfaces as in the case of handmade A pattern can be formed.

  That is, when the first squeezing means squeezes the sheet body, the passing region is closed with the wrinkles on the sheet body, and the tip of the food continuously formed in a rod shape is closed by the second squeezing means. Even when the sheet is cut by a predetermined amount, the sheet body is squeezed and wrinkled. Therefore, the whole of the sheet body squeezed by the first squeezing means and the second squeezing means is wrinkled. The state is realized. Since the first squeezing means and the second squeezing means are spaced apart from each other by a predetermined distance, the cut food is filled inside the sheet body closed by the first squeezing means and the second squeezing means. In this state, the wrinkled portion of the sheet body is pressed, and a deeply drawn drawing pattern is formed on the entire top, bottom and side surfaces of the cut food material.

  In that case, since the sheet | seat body can be expanded-contracted, it can also swell according to the quantity of the cut foodstuff, and the cut foodstuff is shape | molded by the rounded shape as a whole. Moreover, in the upper surface part of the foodstuff cut while being squeezed with the sheet body by the second squeezing means, the foodstuff has a shape protruding in a square shape, and can be finished in a shape unique to the tea width drawing. On the other hand, since the sheet body that has been previously squeezed by the first squeezing means comes into contact with the lower surface portion of the food material, it does not have a protruding shape.

  By releasing the squeezing operation of the first squeezing means, the molded product thus formed can be taken out downward with the sheet body open, and a series of operations from the forming of the food to the removal can be performed efficiently in a short time. Can do.

  In addition, the first diaphragm includes a support member that supports the cut food and a support control unit that moves the support member up and down so as to contact the lower surface of the cut food. When the squeezing operation of the means is released and the sheet body is opened, the support member can be raised to receive the food, and the molded product can be taken out in a stable state without losing its shape.

  Hereinafter, the present invention will be described in detail based on embodiments shown in the accompanying drawings. The embodiments described below are preferable specific examples for carrying out the present invention, and thus various technical limitations are made. However, the present invention is particularly limited in the following description. Unless otherwise specified, the present invention is not limited to these forms.

  FIG. 1 is an overall front view of a drawing-formed food forming apparatus 1. In the molding apparatus 1, a food supply mechanism 4 and a rod-shaped molding mechanism 7 are installed on the upper portion of the base 3, and a drawing mechanism 2 is attached below the food supply mechanism 4. Below the squeezing mechanism 2, a support mechanism 6 for supporting the molded product via a belt conveyor 5 and a conveyor belt 50 for conveying the molded product is attached.

  When the food material is fed into the hopper 40, the food material supply mechanism 4 is fed downward by a screw (not shown) in the hopper 40 and is pressure-fed from the vane pump 41 to the rod-shaped forming portion 42. As will be described later, the food material is continuously formed in a rod shape from the rod-shaped forming mechanism 7 and supplied to the drawing mechanism 2. In FIG. 1, two hoppers 40 and two vane pumps 41 are provided, and the first food material F1 and the second food material F2 of different colors are put into the hoppers 40, respectively.

  FIG. 2 is a schematic cross-sectional view regarding the rod-shaped forming mechanism 7 and the drawing mechanism 2. The rod-shaped forming mechanism 7 includes a double nozzle composed of an outer nozzle 70 and an inner nozzle 71 on the lower side. The inner nozzle 71 is disposed inside the outer nozzle 70, and the opening at the lower end thereof is the opening of the outer nozzle 70. On the other hand, it is set to be concentric.

  The inner nozzle 71 is fixedly attached to the lower end opening 72 a of the movable pipe member 72 so that the side opening 72 b of the movable pipe member 72 communicates with the supply pipe 42 connected to one vane pump 41. It is attached.

  The movable pipe member 72 is formed in a cylindrical shape, and no opening communicating with the inside other than the lower end opening 72a and the side opening 72b is formed, and a mounting base 72c is provided at the upper part. . The movable pipeline member 72 is inserted from above into a mounting opening 44 formed between the supply pipelines 42 and 43 and is slidably mounted in the vertical direction. A seal member is provided on the outer peripheral surface of the upper portion of the movable pipe member 72 between the mounting opening 44 and the food material does not leak.

  Above the movable duct member 72, a drive unit 75 made of an air cylinder is placed and fixed on an attachment base 74 provided on the upper part of the base 3. The lower end of the drive rod 76 extending below the drive unit 75 is fixed to the mounting base 72 c of the movable duct member 72. Therefore, the movable pipe member 72 can be moved up and down by driving the drive rod 76 by the drive unit 75. When the movable pipe member 72 moves up and down, the side opening 72b is displaced with respect to the supply pipe 42, but the supply pipe 42 is not communicated with the outside or the supply pipe 43. An opening shape of the side opening 72b is formed.

  The outer peripheral edge of the lower end opening of the inner nozzle 71 is set to have the same diameter as or slightly larger than the inner peripheral surface of the lower end opening of the outer nozzle 70, and the movable pipe member 72 is lowered to move the inner nozzle 71 to the outer nozzle.

  The outer nozzle 72 is connected to a lower end opening 73 a of a communication pipe 73 that communicates with the supply pipe 43 connected to the other vane pump 41.

  The second food material F2 is pumped from the supply pipeline 42 into the movable pipeline member 72 and is continuously discharged from the inner nozzle 71 to be formed into a continuous bar shape. The first food material F <b> 1 is pumped from the supply pipe 43 to the communication pipe 73 and discharged from the outer nozzle 70. When the movable pipe member 72 is raised and the inner nozzle 71 is positioned at an open position (see FIG. 2) separated from the outer nozzle 70, the first food material F1 is discharged from the outer nozzle 70 to form a rod shape. Is formed into a cylindrical shape so as to cover the outer peripheral surface of the second food material F2. When the movable pipe member 72 is lowered and positioned at the closed position (see FIG. 3) where the inner nozzle 71 is in contact with the outer nozzle 70, the discharge of the first food material F1 from the outer nozzle 70 is temporarily performed. When stopped, the second food F2 is continuously discharged without being covered with the first food F1.

  Therefore, if the movable pipeline member 72 is moved up and down repeatedly at a predetermined timing and alternately positioned at the closed position and the open position, the first food material F1 covers the outer peripheral surface of the second food material F2 formed into a rod shape. The cylinder is intermittently formed.

  The length of the portion covered with the first food material F1 on the outer peripheral surface of the second food material F2 is set so as to be substantially equal to or shorter than the interval set by the interval adjusting member 22 of the diaphragm mechanism 2 described later. In addition, the interval between the portions not covered with the first food material F1 is desirably set so as to be substantially equal to or wider than the thickness of the shutter piece 211 of the second diaphragm shutter 21 described later. What is necessary is just to set the length of the 1st foodstuff F1 coat | covered by the outer peripheral surface of the 2nd foodstuff F2, and the space | interval of the part which is not coat | covered by how much the 2nd foodstuff F2 is exposed to the foodstuff to shape | mold.

  The movement control of the movable pipe member 72 for controlling the discharge of the first food material F1 is driven and controlled by a control device (not shown).

  And the foodstuff rod-shaped by the rod-shaped molding mechanism 7 is supplied to the lower drawing mechanism 2. In addition, the lower end opening of the outer nozzle 70 and the inner nozzle 71 can be made into various shapes such as an ellipse in addition to a circle, for example, according to the shape of the food to be molded.

  The aperture mechanism 2 includes a first aperture shutter 20 and a second aperture shutter 21, and an interval adjusting member 22 is disposed between the two shutters. The first aperture shutter 20 includes six shutter pieces 201, and each shutter piece 201 is attached to the drive shaft 23 and reciprocally swings around the drive shaft 23. The second diaphragm shutter 21 includes six shutter pieces 211, and each shutter piece 211 is attached to a drive hollow shaft 24 provided concentrically with the drive shaft 23 and reciprocates around the drive hollow shaft 24. It swings.

  FIG. 5 is a plan view on the plane T in FIG. 2 and shows the shutter drive mechanism of the second aperture shutter 21. FIG. 5A shows a state where the six shutter pieces 211 are rotated and opened. Each drive hollow shaft 24 to which each shutter piece 211 is attached is fitted to the outer periphery of the drive shaft 23 so as to be concentrically rotatable. A circular flange 212 is provided on the upper portion of each drive hollow shaft 24 in the frame 25. Are fixed respectively. The flanges 212 are connected to each other with a link 213 pivoted, and one link 213 is extended to be pivotally connected to a rotating shaft 214 of a drive motor (not shown).

  By rotating the rotating shaft 214, the link 213 is linked and the flange 212 is rotated synchronously. Similar to the first aperture shutter 20, each shutter piece 211 in FIG. 5A is opened, and the rotation shaft 214 is rotated clockwise by a predetermined angle as shown in FIG. The pieces 211 are rotated and closed so that their tips are abutted against each other. Therefore, by rotating the rotary shaft 214 back and forth by a predetermined angle, each shutter piece 211 swings back and forth and opens and closes.

  As shown in FIG. 5C, one end surface 211A of each shutter piece 211 is formed in a convex shape and the other end surface 211B is formed in a concave shape, and one end surface 211A is one adjacent shutter piece 211. The other end surface 211B is set to be in contact with and the other end surface 211B is set to be in contact with one end surface 211A of the other adjacent shutter piece 211. Then, one end surface 211A and the other end surface 211B operate so as to open and close while sliding, as the shutter pieces 211 rotate.

  Between each shutter piece 211 and each shutter piece 201, a ring-shaped interval adjusting member 22 is inserted into the drive shaft 23, and the interval adjusting member 22 having a predetermined thickness is fitted to the food to be molded. If attached, the space | interval of the 1st aperture shutter 20 and the 2nd aperture shutter 21 can be adjusted.

  A through-hole 26 is formed in the central portion of the frame 25, and an outer nozzle 70 and an inner nozzle 71 are inserted into the through-hole 26 from above. An opening when the first diaphragm shutter 20 and the second diaphragm shutter 21 are opened is formed corresponding to the through hole 26.

By locking the upper end opening 9a to the locking hook 82, FIG. As shown in (b), the sheet body 9 is set so as to cover the ventilation duct 81. Therefore, the air jetted from the ventilation pipe 81 comes to circulate along the inner surface side of the sheet body 9. Then, the lower end opening 9b of the sheet body 9 that locks the upper end opening 9a is pulled and fitted into the fitting portion 27 on the lower surface of the first aperture shutter 20, as shown in FIG.

  As shown in FIG. 7, the lower end opening 9 b of the sheet body 9 is attached by fixing one end of an elastic attachment string 91 to the lower end opening 9 b and forming the other end in a ring shape to form a first aperture shutter 20. You may make it latch on the suitable latching | locking part of the lower surface of this, or the upper surface of the flame | frame 25. FIG.

  By attaching the sheet body 9 as described above, the sheet body 9 is disposed so as to surround the passage region of the rod-shaped food material continuously formed from the rod-shaped forming mechanism 7, and the first aperture shutter is disposed so as to surround the sheet body 9. 20 and the second aperture shutter 21 are arranged.

  A belt conveyor 5 is provided below the squeezing mechanism 2. The conveyor belt 50 of the belt conveyor 5 is disposed so as to pass below the opening of the first aperture shutter 20, and is transported in a predetermined direction by the rotational drive of the drive roller 51.

Thus, the support member 60 moves up and down. The conveyor belt 50 is lifted by the vertical movement of the support member 60 and rises to the inside of the aperture mechanism 2.

  FIG. 8 is a perspective view of the support member 60. The support member 60 is attached and fixed to a mounting portion provided between the conveyor belts 50 with the upper end of the support rod 61 bent horizontally. As shown in the cross-sectional view of FIG. 2, the support member 60 is formed in a curved shape in the concave portion so that the central portion 60 a of the concave portion is slightly raised.

  FIGS. 9 to 12 are plan views (FIGS. (A) and (b)) of the first diaphragm shutter 20 and the second diaphragm shutter 21 showing the molding process of the molding apparatus 1, and schematic sectional views of the diaphragm mechanism 2 (( c) FIG.

  In FIG. 9, with the first aperture shutter 20 and the second aperture shutter 21 opened, air is injected from the injection hole of the ventilation duct 81 and is applied to the inner surface of the sheet body 9 when the second aperture shutter 21 is cut. The adhered food material and the molded product H are easily separated. Further, the sheet body 9 with the squeezed swell is swelled by the jetted air, and staking is performed.

  First, the shutter piece 201 of the first aperture shutter 20 performs a closing operation. At that time, the closing operation of the shutter piece 201 is performed before the tip of the bar-shaped food material continuously formed from the bar-shaped forming mechanism 7 reaches the first aperture shutter 20. That is, the shutter piece 201 is closed on the downstream side in the supply direction of the front end portion of the food material (lower side in FIG. 9), and the food passage area is closed.

  In FIG. 10, the first diaphragm shutter 20 is closed and the food passage area is blocked in advance, and the sheet body 9 is gathered and squeezed in one place by closing the first diaphragm shutter 20, which causes wrinkles. It is in a state. Then, the closing operation of the second aperture shutter 21 is started while the entire aperture mechanism 2 is raised. For this reason, the portion of the sheet body 9 above the portion closed by the first aperture shutter 20 is loosened, and a predetermined length of food is introduced between the first aperture shutter 20 and the second aperture shutter 21. . In this case, the operation of introducing the food so that the portion not covered by the first food F1 intermittently formed on the outer peripheral surface of the second food F2 formed in a rod shape is substantially opposed to or located below the second aperture shutter 21. Is done.

  In FIG. 11, the second diaphragm shutter 21 is closed, and the sheet body 9 is gathered in one place and squeezed to cut the rod-shaped food material. At this time, the diaphragm mechanism 2 is lowered in accordance with the closing operation of the second diaphragm shutter 21 and cuts in accordance with the supply speed of the bar-shaped food material continuously formed from the bar-shaped molding mechanism 7. Therefore, the food supplied continuously is cut without being stopped, and the cut tip is prevented from being swollen.

  The cut and divided foods are filled in the sheet 9 closed up and down by the first diaphragm shutter 20 and the second diaphragm shutter 21, and the food is divided by the first diaphragm shutter 20 and the second diaphragm shutter 21. Ingredients are pressed against the sheet body that has been closed and the wrinkles are in its entirety, and the foodstuffs are pressed between the wrinkles. In that case, since the sheet | seat body 9 can expand-contract, the filled foodstuff is shape | molded by the rounded shape. In this way, a deeply drawn drawing pattern is formed on the entire top, bottom and side surfaces of the foodstuff. And the lower part is coat | covered with the 2nd foodstuff F2 on the outer surface of the cut | disconnected foodstuff, and the upper part is also coat | covered with the 2nd foodstuff F2 depending on the case. After the aperture pattern is formed, the first aperture shutter 20 starts to open and the support member 60 is raised.

  In FIG. 12, the first aperture shutter 20 is in an open state, the support member 60 is raised in the open space, and the concave portion of the support member 60 is in contact with the lower surface of the molded product H via the conveyor belt 50. Is done. At this time, since the central portion 60a of the concave portion of the support member 60 is raised, the bottom surface of the molded product H is formed in a recessed state. Then, the second aperture shutter 21 starts an opening operation and air injection is started from the injection hole of the ventilation pipe 81.

  The jetted air flows along the inner surface of the sheet body 9 to promote separation between the sheet body 9 and the food material, and the support member 60 that has received the molded product H descends. The molded product H descends in a state of being placed on the upper surface of the conveyor belt 50 and is conveyed by the belt conveyor 5 as it is.

  FIG. 13 is a perspective view (FIG. 13A) and a cross-sectional view (FIG. 13B) regarding the molded product H. The entire molded product H is formed into an elliptical shape in plan view, and a deeply drawn drawing pattern is formed on the entire upper surface, lower surface, and side surface. Such an overall shape can be formed into various shapes such as a circular shape in plan view and an elliptical shape by changing the shapes of the lower end openings of the outer nozzle 70 and the inner nozzle 71. The height of the molded product H can be adjusted by changing the thickness of the interval adjusting member 22. In addition, a square protrusion J is formed on the upper surface, and a central portion K on the lower surface is curved in a concave shape, so that it can be finished in a shape unique to a handmade tea width drawing. And from the middle to the lower part of the molded product H is covered with the first food F1, and the portion of the protrusion J is also slightly covered with the first food F1. The second ingredient F2 is exposed between the first ingredients F1, and by using the second ingredient F2 having a different color from the first ingredient F1, the first ingredient F1 expands in the shape of a petal from below and has a flower pattern. It comes to show the hue of.

  In this way, it becomes possible to form a novel draw-formed food in which various colors and patterns are exposed by combining various foods, and the variation of moldable food can be greatly expanded.

  In this example, the second food material F2 is molded so as to be partially covered with the first food material F1. However, the second food material is fed into the food material supply mechanism 4 with three kinds of food materials. It is possible to draw the packaged food by forming the food for inner material in the center of the food F2 and molding it. 13 (c) and 13 (d) show a perspective view and a cross-sectional view of the wrapping molded product H '. The wrapping molded product H' covers the foodstuff G for inner material that becomes a ridge and covers it. The first food material F1 and the second food material F2 are formed, and a deeply drawn drawing pattern is formed on the entire outer surface of the food material to be coated.

  In the above-described embodiment, the movable pipe member 72 is moved up and down to alternately move the inner nozzle 71 to the open position or the closed position to discharge or stop the first food material F1 from the outer nozzle 70. Alternatively, the ejection of the outer nozzle 70 may be controlled by moving the inner nozzle 71 up and down.

  FIG. 14 is a schematic cross-sectional view regarding the modified example. 14A shows a state where the inner nozzle 71 is positioned at the closed position, and FIG. 14B shows a state where the inner nozzle 71 is positioned at the open position.

  In the above embodiment, six shutter pieces are used as the first diaphragm shutter 20 and the second diaphragm shutter 21, but the number of shutter pieces is not particularly limited. The shutter drive means uses a drive mechanism that opens and closes when each shutter piece reciprocally swings around the drive shaft. However, the present invention is not limited to this, and for example, as shown in FIG. As shown in FIGS. 16A and 16B, each shutter piece 302 slides in the direction of the arrow and moves linearly to open and close, or as shown in FIGS. Various drive mechanisms such as a drive mechanism that opens and closes by swinging while linearly moving in accordance with the rotational motion of can be used.

  The example shown in FIGS. 17 and 18 is a case where the rotating shaft 305 continuously rotates in one direction to open and close the shutter, and in FIG. 17, the sliding surface with the shutter piece adjacent to the shutter piece 304 is shown. The shutter piece 304 can be opened and closed twice while the rotation shaft 305 is rotated once. In FIG. 18, the sliding surface of the shutter piece 304 adjacent to the shutter piece 304 is formed on one side, and the shutter piece 304 performs the opening / closing operation once while the rotation shaft 305 rotates once. Further, regarding the shape of each shutter piece, various shapes such as those having a linear side as shown in FIG. 15 or FIG. it can.

  In the above example, the diaphragm operation is performed by rotating a plurality of shutter pieces. However, the diaphragm operation other than the rotation operation can be used, and is not particularly limited. For example, as shown in FIG. 19, a squeezing operation may be performed using a rod-shaped slide member 306. The slide member 306 is slidably inserted into a through-hole formed in the donut-shaped base 307, and each slide member 306 advances toward the center of the base 307 and its tip is concentrated at the center. It is supposed to be. A spring is mounted in the through-hole, and this spring acts to urge the slide member 306 in the retracting direction. Around the base 307, a donut-shaped rotating body 308 is rotatably disposed so as to surround the base 307, and a tooth row 309 that meshes with the drive gear 311 is formed on the outer peripheral surface thereof. A cam surface 310 that contacts the rear end of the slide member 306 is formed on the peripheral surface. Accordingly, when the rotating body 308 is rotated by the drive gear 311, the cam surface 310 is rotated and presses the rear end of the slide member 306, whereby the slide member 306 moves forward and backward.
