The product body is supported and placed on the top surface of the pallet by legs 204 (FIG. 3) provided at the bottom of the product.

  FIG. 6 is a side view showing a state in which the fixing means 94 is held on the unit mounting member 96 of the pallet. In this figure, the lock bush 115 is removed. FIG. 7 is a block diagram showing a part of the fixing means 94 held by the unit mounting member 96 together with the product-based attachment mounting portion 203 and the engagement attachment 202. FIG. 8 is a side view showing the hook subunit 120 to which a pair of hook-shaped fixing members 111 are connected. 6-8, the hook-shaped fixing members 111 are shown in an opened state. Further, FIG. 9 is a side view of the hook subunit 120 with the hook-shaped fixing members 111 closed, and FIG. 10 is a perspective view thereof. FIG. 11 is a side view showing a state in which the hook subunit 120 is mounted on the casing 114.

  As shown in these drawings, the fixing means 94 includes a pair of hook-shaped fixing members 111 and 111 and a lock bush 115, as well as connecting members 112 and 112, a sliding member 113, a casing 114, and the like. . As can be seen from FIGS. 8, 9, and 10, the hook subunit 120 is formed by connecting hook-shaped fixing members 111 and 111, connecting members 112 and 112, and a sliding member 113. That is, one end of the connecting members 112 and 112 is rotatably connected to the projecting portion provided on the side surface of the sliding member 113 by the shafts 116 and 116. The hook-shaped fixing members 111 and 111 are rotatably connected to the other end portions of the connecting members 112 and 112 by shafts 117 and 117. The swing pins 111a and 111a are formed so as to protrude on both sides of the lower side surface of the hook-shaped fixing member 111, and the swing pins 111a and 111a of the hook-shaped fixing members 111 and 111 are formed on the casing 114 (not shown). The hook subunit 120 is movably held with respect to the casing 114 by being inserted into the swing pin receiving portion.

  As shown in FIG. 7, the sliding member 113 is fitted in a sliding portion 114a provided in the casing 114, and can slide up and down in the sliding portion 114a. In addition, a hole into which a push-up bar 118 for pushing up the slide member 113 is inserted is provided at the center of the bottom of the slide part 114a, and the push-up bar 118 is slidably supported up and down. A disk member 119 is fixed to the lower end portion of the push-up bar 118 that has come out of the casing 114, and a compression spring 121 is disposed below the disk member 119. The disc member 119 and the compression spring 121 are disposed in a storage portion 96a formed in the unit mounting member 96 to which the fixing means 94 is mounted.

  In such a configuration, the sliding member 113 is biased upward via the push-up bar 118 by the biasing force of the compression spring 121, and when the sliding member 113 is positioned at the upper end of the sliding range, it is fixed in a hook shape. The members 111 and 111 are released and do not fix the product (does not engage with the product engagement attachment 202), and are in an unfixed state. When the product 200 is mounted on the pallet 91, the sliding member 113 is pushed downward by the engagement attachment 202 attached to the lower surface of the product base 201, the compression spring 121 is compressed, and the sliding member 113 is moved downward. Moving. The movement of the sliding member 113 is transmitted to the hook-shaped fixing members 111, 111 via the connecting members 112, 112, and the hook-shaped fixing members 111, 111 center on the swing pins 111 a, 111 a fitted to the casing 114. And the hooks are closed, and the hook-shaped fixing members 111 hold the engagement attachment 202 sandwiched from both sides.

  Here, the lock bush 115 is connected to the inside of the pallet with an operation lever 97 (FIGS. 1, 3 and 4) provided so as to protrude from the side surface of the pallet, and when the operation lever 97 is pulled forward, the lock bush 115 is attached to the outside of the pallet. The lock bush 115 is horizontally moved to the inside of the pallet by horizontally moving to the side and pushing the operating lever 97 to the back side. As shown in FIG. 12, the lock bush 115 has a shape in which two convex rod portions 115b and 115b on both sides are connected to each other by a bottom portion 115a, and the protrusion further protrudes from the tips of the convex rod portions 115b and 115b. Portions 115c and 115c are formed. The fitting portions 115c and 115c have a substantially rectangular cross-sectional shape, and are fitted into fitted portions 112a (FIGS. 8 and 9) provided on the connecting member 112 of the hook subunit. The casing 114 is provided with notches 114b and 114b (FIG. 11) through which the fitting portions 115c and 115c of the lock bush 115 can pass. Further, the unit mounting member 96 on the pallet side is also provided with openings 96b and 96b (FIG. 6) through which the convex bar portions 115b and 115b of the lock bush 115 can pass.

  When the sliding member 113 is lowered and the hook-shaped fixing members 111 are closed, as shown in FIG. 11, the fitted portion 112a of the connecting member 112 overlaps the notch 114b of the casing. When the connecting member 112 is in a substantially horizontal state, the rectangle of the fitted portion 112a is also in a substantially horizontal state, and the fitting portion 115c of the lock bush 115 can be fitted into the fitted portion 112a. Therefore, when the hook-shaped fixing members 111 are closed, the operating lever 97 is operated so that the fitting portion 115c of the lock bush 115 is fitted to the fitted portion 112a of the connecting member 112, thereby connecting the connecting members on both sides. 112 and 112 are fixed by the lock bush 115 via the casing 114, whereby the movement of the hook subunit 120 is restricted and the fixing means 94 is locked. That is, the product 200 is fixed on the pallet 91 via the product base 201 by locking the fixing means 94 in a state where the product engagement attachment 202 is sandwiched (see FIGS. 3 and 4). FIG. 13 shows a state in which the hook-shaped fixing members 111 and 111 are closed, the engagement attachment 202 is sandwiched, and the fixing means 94 is locked by the lock bush 115.

  As described above, in the pallet 91 of this example, when the operation lever 97 is operated (pulled toward the front side of the pallet) to release the lock of the fixing means 94, the hook-shaped fixing members 111 and 111 are moved by the urging force of the spring 121. It is automatically released. When the product 200 is mounted on the pallet 91 in this state, the sliding member 113 is lowered by the weight of the product, the hook-shaped fixing members 111 and 111 are closed, and the engagement attachment 202 is clamped. Then, the product 200 can be easily fixed on the pallet 91 by pressing the operation lever 97 to lock the fixing means 94. Since the hook-shaped fixing members 111 and 111 are engaged with the engagement attachment 202 simply by placing the product on the pallet, it is possible to fix the product by simply pressing the operation lever 97, which is extremely simple. The product can be fixed directly on the pallet. When unloading the product, it is only necessary to pull the operation lever 97 to unlock the fixing means 94 and unload the product 200 from the pallet. After the product is lowered, the sliding member 113 is lowered by hand (or foot) to close the hook-shaped fixing members 111 and 111, and the operation lever 97 is pushed to lock the fixing means 94.

  By the way, when the sliding member 113 is lowered and the hook-shaped fixing members 111 are closed, the lower portion 111b (FIG. 9) on the back surface of the hook-shaped fixing member 111 slides on the inner wall of the casing 114 and slides. The back surface of the hook-shaped fixing member 111 (the lower portion 111b) and the inner wall of the casing are back-to-back at the lowest point of the member 113, so that the pair of hook-shaped fixing members 111, 111 are in the pallet width direction (the left-right direction in FIG. 9). ) Is restricted. The direction perpendicular to the pallet (the longitudinal direction of the pallet) is regulated by the swing pin 111 a of the hook-shaped fixing member 111 being fitted to the casing 114.

  Further, as shown in FIG. 9, the sliding member 113 has leg portions 113a extending downward at the four corners, and the leg portions 113a contact the bottom surface of the sliding portion 114a (FIG. 7) of the casing 114. The range of downward movement is regulated by touching. Further, the lower end portion of the leg portion 113a has a shape that protrudes outward, and the protrusion portion comes into contact with a jaw portion (not shown) provided at the upper end portion of the sliding portion 114a, so that the upper portion of the sliding member 113 is The movement range is restricted, and at the same time, the sliding member 113 is configured not to come off the sliding portion 114a.

  Further, as shown in FIG. 10, the hook-shaped fixing member 111 has a linear portion 111c extending in the pallet front-rear direction and circular portions 111d and 111d that wrap around in the pallet width direction from both ends thereof. Yes. The straight portion 111c restricts the movement of the product (the engagement attachment 202) in the pallet width direction, and the circular portions 111d and 111d restrict the movement of the product (the engagement attachment 202) in the pallet front-rear direction. Thereby, when the product 200 is placed and fixed on the pallet 91, the product does not slide on the pallet surface, and the product is firmly fixed to the pallet 91. Note that the shape of the hook-shaped fixing member 111 is determined together with the shape of the fixed portion on the product side, and does not necessarily need to have a linear portion. For example, it may be a plane shape such as a substantially horseshoe shape or a parabola shape. In short, it is only necessary to be able to engage with the fixed part on the product side and to restrict the movement of the product on the plane (on the pallet placement surface).

  Further, as shown in FIG. 7 (cut portion), the hook-shaped fixing member 111 has a flange portion 111e in which the upper end portion on the inner side protrudes forward and overhangs. Since the hook-shaped fixing member 111 has the brim portion 111e, when the hook-shaped fixing member 111 is engaged with the engagement attachment 202 of the product, the engagement attachment 202 (that is, the product) is prevented from being pulled upward. The product 200 can be reliably fixed on the pallet 91.

  Further, the protrusion amount of the flange portion 111e is constant in the straight portion 111c, but the protrusion amount increases from the boundary portion (corner portion) between the straight portion 111c and the circular portion 111d to the tip of the circular portion 111d. It is getting smaller gradually. With this configuration, the hook-shaped fixing member 111 can be controlled in the shape of the hook-shaped fixing member 111 on the plane of the engagement attachment 202 (on the pallet mounting surface) and can be prevented from being pulled upward. When the 111 is closed, the engagement attachment 202 can be smoothly and reliably engaged. Therefore, it is difficult for the hook-shaped fixing member 111 to be poorly engaged when the product is fixed, and the product can be reliably fixed. In addition, when the hook-shaped fixing member is configured to have a curved planar shape that does not have a straight portion, the protrusion amount is gradually reduced from the center portion to both ends of the hook-shaped fixing member. Just do it. Or you may comprise so that the protrusion amount of the predetermined range of a center part may be made constant, and protrusion amount may become small gradually as it goes to a front-end | tip from there.

  Further, as shown in FIG. 12, two convex portions 115d and 115d are formed on the inner side (inside of the pallet) of the bottom side portion 115a of the lock bush 115. The convex portions 115d and 115d have an inverted U-shaped cross-sectional shape and are fitted into lock bush fitting portions 96c and 96c provided on the unit mounting member 96 on the pallet side. When the fixing means 94 is locked by the lock bush 115, the center portion (the portion between the convex portions 115d and 115d) of the bottom side portion 115a of the lock bush comes into contact with the contact portion 96d of the unit mounting member 96 and the convex portion. 115 d and 115 d are fitted into the fitting portions 96 c and 96 c of the unit mounting member 96, whereby the lock bush 115 is supported and fixed to the unit mounting member 96.

Next, a second embodiment of the present invention will be described.
FIG. 14 is a perspective view illustrating a pallet 1 that is a first example of the second embodiment and an example (in-body discharge type) of an image forming apparatus loaded on the pallet 1. As shown in this figure, the pallet 1 is provided with four fixing portions 2. Each fixing portion has a pair of hooks 3 and 3, respectively. In FIG. 14, the hooks 3 and 3 are attached to only one fixing portion 2 in order to avoid complexity. Reference numerals 6 and 6 denote lock members which will be described later.

  As shown in FIG. 15, the hooks 3 and 3 of the fixed portion 2 are rotatably supported by the base plate 4 via the shafts 3a and 3a, and the hooks are opened as shown in FIG. And (b) The hook can be closed as shown in FIG. The base plate 4 is set so as to be movable in the vertical direction within the fixed portion mounting space 7 provided in the pallet 1 and is urged upward by a biasing member (not shown). Therefore, in a non-stacked state in which no product is mounted on the pallet, the base plate 4 is positioned at the upper end in the mounting space 7 as shown in FIG. The tension springs 5 and 5 are installed between the hooks 3 and 3 and the base plate 4, and the hooks 3 and 3 are opened as shown in FIG. In FIG. 14, the hooks 3 and 3 are shown in a closed state.

  When loading the product 100 on the pallet 1, the product is mounted on the pallet by adjusting the position of the product so that the legs 101 provided on the bottom of the product are on the fixed portion 2. In this example, the positions of the respective fixing portions 2 of the pallet 1 are set so as to correspond to the leg portions 101 provided at the four corners of the bottom surface of the product 100.

  Then, when the product 100 is mounted on the pallet 1, the leg portion 101 provided on the bottom of the product comes into contact with the inner surfaces of the opened hooks 3 and 3 to push down the fixing portion 2. At this time, the outer corners of the hooks 3, 3 are brought into contact with the convex portions 8, 8 of the pallet 1, so that the hooks 3, 3 on both sides are rotated so that the product 100 is completely placed on the pallet 1. Then, the hooks 3 and 3 are closed so as to wrap the product legs 101 from both sides as shown in FIG. With the hooks 3 and 3 closed, the lock members 6a and 6a of the lock members are pushed into the fixed portion mounting space 7 by pushing the lock member 6 whose end is protruding from the side of the pallet into the pallet.
