Various operations of the image forming apparatus 100 are controlled by executing the stored control program. Specifically, the controller 130 controls the operations of the X-axis direction feed motor 103, the image forming carriage (ink head) 105, and the Y-axis direction scan motor 106, respectively. The external computer device 140 is a personal computer (so-called personal computer) including an input device 141 composed of a keyboard and a mouse and a display device 142 composed of a liquid crystal display.

(Operation of Image Forming Apparatus 100)
Next, the operation of the image forming apparatus 100 configured as described above will be described. First, the user arranges the recording medium support tables 112 on the front side and the rear side of the image forming apparatus 100 in the platen 101 and connects them to the connecting portions 111 arranged adjacent to the platen 101. In this case, the recording medium pressing mechanism 120 is stationary in a state where it is placed on the stopper 113c of the table portion 113 by the weight of the support arm 121, the roll body 122, and the weight body 123, that is, in a state where it is positioned at the lower limit position. doing.

  Next, the user connects the external computer apparatus 140 and the image forming apparatus 100 via the interface 131, and turns on the power supply of the external computer apparatus 140 and the image forming apparatus 100, respectively. As a result, the external computer device 140 enters a standby state in which it waits for an instruction from the user by executing a predetermined control program (not shown). Further, the image forming apparatus 100 executes a predetermined control program (not shown) stored in advance in the ROM in the controller 130 to return the origin of the image forming carriage 105, and then issues an instruction from the external computer device 140. It becomes a waiting state to wait. In this case, the origin of the image forming carriage 105 is one movable limit position (the rightmost end in the drawing) within the movable range of the image forming carriage 105 in the main scanning direction.

  Next, the user sets a recording medium WK made of a foam material on which an image is to be formed on the platen 101. Specifically, the user places one end of the recording medium WK on the platen 101 and places the other end on the recording medium support table 112 arranged on the rear side in the figure, By lowering the pinch roller 104, the same end is sandwiched between the pinch roller 104 and the grid roller 102.

  Next, the user operates the input device 141 of the external computer apparatus 140 to instruct the image forming apparatus 100 to form an image. In this case, the user creates in advance image data to be formed on the recording medium WK on the external computer device 140. In response to the instruction, the external computer device 140 generates processing image data corresponding to the image data to be formed stored in the external computer device 140 and outputs it to the image forming device 100 (controller 130). To do. In this case, the processing image data is image data for printing processing for forming an image by a set of ink droplets.

  As a result, the image forming apparatus 100, specifically, the controller 130 built in the image forming apparatus 100, determines whether the image forming carriage 105 and the recording medium WK are based on the processing image data output from the external computer device 140. While changing the relative positional relationship, the operation of the image forming carriage 105 is controlled to execute an image forming process by printing on the recording medium WK.

  Specifically, the controller 130 controls the operation of the X-axis direction feed motor 103 to rotationally drive the grid roller 102 to displace the recording medium WK held on the platen 101 in the X-axis direction in the sub-scanning direction shown in the figure. Let Further, the controller 130 controls the operation of the Y-axis direction scan motor 106 to rotationally drive a drive belt (not shown), thereby displacing the image forming carriage 105 in the Y-axis direction main scanning direction. Further, the controller 130 controls the operation of the image forming carriage 105 to eject ink droplets toward the recording medium WK to form an image.

  In the image printing process on the recording medium WK, the recording medium WK placed on the platen 101 is displaced along the X-axis direction by the grid roll 102 and the pinch roll 104. For this reason, a part of the recording medium WK conveyed to the outer sides of the front side and the rear side of the image forming apparatus 100 with respect to the platen 101 is respectively on the front side and the rear side of the image forming apparatus 100 with respect to the platen 101. It is guided onto the table portion 113 of the recording medium support table 112 arranged adjacent to and supported by the table portion 113.

It is pressed by a recording medium pressing mechanism 120 provided at 113. Specifically, the recording medium WK conveyed in the forward direction toward the recording medium pressing mechanism 120 further moves forward after colliding with the roll body 122, thereby pressing the roll body 122 in the forward direction. Therefore, in the recording medium pressing mechanism 120, the roll body 122 rotates in a direction corresponding to the forward direction of the recording medium WK, and the support arm 121 is rotationally displaced toward the upper side in the drawing. As a result, the roll body 122 is put on the recording medium WK and the recording medium WK is pressed. That is, the recording medium WK that is in the process of being conveyed in the forward direction rotates and displaces the roll body 122 upward in the figure against the weight of the weight body 123.

  While the roll body 122 is positioned on the recording medium WK, the roll body 122 continues to press the upper surface of the recording medium WK while rotating. Thereby, the warp of the portion between the pinch roller 104 and the roll body 122 is corrected and the recording medium WK becomes a flat state. As a result, image formation is performed with high accuracy on the recording medium WK on the platen 101. That is, the recording medium pressing mechanism 120 corresponds to the recording medium pressing means according to the present invention.

  On the other hand, in the process of printing an image on the recording medium WK, when the recording medium WK is conveyed in the backward direction, the roll body 122 rotates in the direction corresponding to the backward direction of the recording medium WK while rotating the recording medium WK. Press the top surface. Then, when the recording medium WK further moves backward, the roll body 122 is removed from the recording medium WK, so that the support arm body 121 that supports the roll body 122 moves toward the stopper 113c below the figure due to the weight of the weight body 123 or the like. Rotating displacement. As a result, the recording medium pressing mechanism 120 returns to the original stationary state by the support arm 121 being lowered together with the roll body 122 and the weight body 123 and being supported by the stopper 113c. That is, the recording medium pressing mechanism 120 repeatedly presses and stops the recording medium WK according to the position of the recording medium WK while an image is formed on the recording medium WK.

  When the image formation on the recording medium WK is completed, the user removes the recording medium WK held on the platen 101. Specifically, the user lifts the pinch roller 104 to separate the pinch roller 104 from the recording medium WK, and then removes the recording medium WK from the platen 101. Then, when forming an image on another recording medium WK, the user sets a new recording medium WK on the platen 101 in the same procedure as described above. In addition, when the user finishes image formation on the recording medium WK, the user turns off the power to the external computer device 140 and the image forming device 100, respectively. Thereby, the image forming operation for the recording medium WK is completed.

  As can be understood from the above description of the operation, according to the embodiment, the image forming apparatus 100 includes the recording medium pressing mechanism 120 that presses the portion of the recording medium WK that protrudes from the platen 101 on the recording medium support table 112. ing. As a result, the image forming apparatus 100 can perform image formation while maintaining the planar shape by pressing the portion of the recording medium WK that protrudes from the platen 101, so that the image formation accuracy can be improved.

  Furthermore, in carrying out the present invention, the present invention is not limited to the above embodiment, and various modifications can be made without departing from the object of the present invention.

  For example, in the above-described embodiment, the image forming carriage 105 is configured by an ink head that forms an image by ejecting ink droplets. However, the image forming carriage 105 is not necessarily limited to the ink head as long as it forms an image on a recording medium by printing or cutting. For example, the image forming carriage 105 can be configured by a cutting head that cuts out an image by cutting the recording medium WK with a blade instead of or in addition to the ink head.

  In the above embodiment, the recording medium pressing mechanism 120 is provided on the recording medium support table 112 arranged on the front side of the image forming apparatus 100 with respect to the platen 101. However, the recording medium pressing mechanism 120 is located on the upstream side and the downstream side in the conveyance direction (X-axis direction in the drawing) of the recording medium WK with respect to the platen 101, in other words, on the front side and the rear side of the image forming apparatus 100. As long as it is provided on at least one of the above. That is, the recording medium pressing mechanism 120 may be disposed on the rear side of the image forming apparatus 100 instead of or in addition to the front side of the image forming apparatus 100 with respect to the platen 101.

  In the above embodiment, the recording medium pressing mechanism 120 is provided in the table portion 113 of the recording medium support table 112. However, the recording medium pressing mechanism 120 can be provided at a place other than the table unit 113 as long as the recording medium WK supported on the table 112 of the recording medium support table 112 can be pressed. For example, the recording medium pressing mechanism 120 can be provided such that the roll body 122 projects to the table portion 113 side of the recording medium support table 112 when the support arm 121 is supported on the platen 101 side.

  Further, in the above embodiment, the recording medium pressing mechanism 120 has the roll body 122 that presses the recording medium WK configured as a cylindrical body. That is, the roll body 122 corresponds to the recording medium pressing body according to the present invention. The recording medium pressing body can be configured by a member other than the roll body 122 as long as the recording medium WK can be pressed. For example, the recording medium pressing body can be configured by a plate-like body having a rectangular cross-sectional shape.

  In the above embodiment, the recording medium pressing mechanism 120 includes the weight body 123. However, the roll body 122 may be configured to be pressed against the recording medium WK by increasing the mass of the roll body 122 or by urging force of an elastic body such as a spring instead of or in addition to the weight body 123. That is, the recording medium pressing mechanism 120 can be configured by omitting the weight body 123.

  In the above embodiment, the recording medium support table 112 is configured to be detachable from the platen 101. Thus, the image forming apparatus 100 connects the recording medium support table 112 to the platen 101 and corrects the flat state when the image is formed on the plate-shaped recording medium WK that needs to be corrected to the flat state. When forming an image on an unnecessary sheet-like recording medium WK, the recording medium support table 112 can be separated from the platen 101 and used separately. That is, the image forming apparatus 100 can form images on a wide variety of recording media WK by detachably configuring the recording media support table 112. However, the image forming apparatus 100 can also be configured by providing the recording medium support table 112 in a fixed state that is not detachable from the platen 101. According to this, the configuration of the image forming apparatus 100 can be simplified.
