Hereinafter, the present invention comprises a handheld mobile printer (hereinafter referred to as "HMP") which is a portable image forming apparatus, and a jig for portable image forming apparatus (hereinafter simply referred to as "jig"). One embodiment applied to a portable image forming system will be described.
First, the basic configuration of the HMP according to this embodiment will be described.

FIG. 1 is an external perspective view showing the HMP 1 according to this embodiment from obliquely above.
The HMP 1 shown in the figure is mainly composed of an upper unit 2 and a lower unit 3. The HMP1 has a roughly rectangular parallelepiped shape as a whole, and its width in the scanning direction (=printing direction: arrow X direction in the drawing) is such that the user can grasp it with his/her palm.

The housing of the HMP1 includes a recording surface 30 that faces a recording portion (image forming portion) of an inkjet head, which will be described later, to a recording material such as paper, an upper surface 31 that is the opposite surface, a scanning direction (arrow X in the figure). It has a left side surface 32 and the like facing the direction). It also has a right side surface 33 facing the scanning direction, a back surface 34 facing the scanning orthogonal direction (the arrow Y direction in the drawing), a front surface 35 facing the scanning orthogonal direction, and the like. The scanning orthogonal direction is a direction orthogonal to the scanning direction of HMP1.

The HMP 1 shown in the figure is in a posture in which the recording surface 30 faces downward in the vertical direction and the upper surface 31 faces upward in the vertical direction. A print button 14 and a power button 15 are provided inside the outer edge (inside the frame) of the upper surface 31. A USB connection port 6 is provided on the left side surface 32 of the upper unit 2.

The USB connection port 6 is for connecting a USB cable. The rechargeable battery (reference numeral 51 in FIG. 3 described later) provided in the HMP1 can be charged by supplying power from an external power source via a USB cable connected to the USB connection port 6. it can.

The user can switch on/off (ON/OFF) the power of the HMP 1 by pressing the power button 15 for a long time. When the power is turned on, the control board provided in the upper unit 2 of the HMP 1 can be caused to acquire image information by short-range wireless communication with an external device such as a smartphone. Then, after placing the HMP1 on the surface of the recording material in a posture in which the recording surface 30 faces the surface of the recording material, the print button 14 is pressed once, and then the HMP1 is scanned in the scanning direction (arrow in the figure) as shown in FIG. An image can be formed on the surface of the recording material by moving it along the (X direction). When the HMP 1 is moved back and forth along the scanning direction (the arrow X direction in the drawing) by the user's moving operation (manual scanning), an image can be formed on the surface of the recording material in each of the forward path and the backward path. it can.

The recording material is not limited to papers such as papers, but includes OHP, cloth, cardboard, packaging containers, glass, substrates, and any other material capable of recording images.

FIG. 3 is a perspective view showing the HMP 1 in a state where the upper unit 2 is opened with respect to the lower unit 3.
As illustrated, the upper unit 2 is supported by the lower unit 3 so as to open and close with respect to the lower unit 3. A battery 51 for supplying power to each device of the HMP 1 is mounted in the internal space of the lower unit 3.

Further, inside the lower unit 3, an ink tank-integrated inkjet head 40 (ink cartridge) that integrally includes a recording unit and an ink tank is detachably mounted. At this time, the recording unit that ejects ink droplets is directed downward in the vertical direction. The inkjet head 40 discharges ink droplets from a recording unit to record an image.

A head pressing plate spring 37 for pressing and locking the inkjet head 40 mounted in the lower unit 3 is fixed to the inner surface of the upper unit 2.

In this HMP1, since the battery 51 is located laterally of the inkjet head 40 in the lower unit 3, the height of the HMP1 can be made lower than that in the configuration located above. As a result, the center of gravity of the HMP1 can be lowered, and it is possible to prevent the HMP1 from falling over during a moving operation (manual scanning).

FIG. 4 is a bottom view of the HMP1 when viewed from the recording surface side.
In the figure, the recording surface 30 of the HMP 1 is provided with an opening 30a for exposing the recording portion 41 of the inkjet head 40 mounted in the lower unit (reference numeral 3 in FIG. 3) to the outside. The recording unit 41 has a plurality of ejection holes 41a, and it is possible to eject ink droplets individually from each ejection hole 41a by driving an actuator (driving source).

In the inkjet head 40, as a drive source for ejecting ink, an electromechanical conversion element (piezoelectric actuator or the like) using a laminated piezoelectric element, a thin film piezoelectric element, or the like, an electrothermal conversion element such as a heating resistor, or vibration. An electrostatic actuator including a plate and a counter electrode can be used.

The ink (liquid) ejected from the ejection holes 41a of the recording unit 41 may be any liquid having a viscosity and surface tension that can be ejected from the ejection holes 41a, and is not particularly limited, but may be heated or cooled at room temperature and normal pressure. Therefore, the viscosity is preferably 30 mPa·s or less. Specifically, the ink (liquid) is a solvent such as water or an organic solvent, a coloring agent such as a dye or a pigment, a polymerizable compound, a resin, a function-imparting material such as a surfactant, DNA, an amino acid or protein, calcium. And the like, biocompatible materials such as, and edible materials such as natural pigments, and the like, solutions, suspensions, emulsions, and the like. These can be used in applications such as ink jet inks, surface treatment liquids, liquids for forming components of electronic devices and light emitting devices, liquids for forming electronic circuit resist patterns, and three-dimensional modeling liquid materials.

Within the outer edge of the recording surface 30, a position detection sensor 8 as a detection means for detecting the position of the HMP 1 on the recording material, a rotatable first left roller portion 17a, a left second roller portion 17b, and a right first roller portion. 18a, a right side second roller portion 18b and the like are provided.

The HMP 1 rotates the above-mentioned four roller portions that are in contact with the surface of the recording material when the user performs a moving operation (manual scanning) in the scanning direction. By providing such a roller portion, the user can easily move the HMP 1 straight along the scanning direction. At this time, only the four roller parts of the HMP 1 are in contact with the surface of the recording material, and the recording surface 30 is not in contact with the surface of the recording material. Therefore, it is possible to form a desired high-quality image while keeping the distance between the recording unit 41 of the inkjet head 40 and the surface of the recording material constant.

The position detection sensor 8 is a sensor that detects the distance to the surface of the recording material, the surface condition (for example, unevenness), and the movement distance of the HMP1, and is an optical mouse (pointing device) of a personal computer, for example. The same as that used is available. The position detection sensor 8 irradiates the place (recording material) where it is placed with light, and reads the state of that portion as a “pattern”. Then, the movement amount is calculated by continuously grasping how the “pattern” moves with respect to the movement of the position detection sensor 8.

FIG. 5 is a block diagram showing a part of the electric circuit of the HMP1.
The control board 57 includes a CPU 55 that performs various kinds of arithmetic processing and program execution, a Bt (Bluetooth (registered trademark)) board 52 for short-range wireless communication, a RAM 53 that temporarily stores data, a ROM 54, a recording control unit 56, and the like. ing. The control board 57 is fixed to a position behind the USB connection port (reference numeral 6 in FIG. 2) in the hollow of the upper unit (reference numeral 2 in FIG. 1).

The Bt substrate 52 performs data communication by short-range wireless communication (Bluetooth communication) with an external device such as a smartphone or a tablet terminal. The ROM 54 stores firmware that controls the hardware of the HMP 1, drive waveform data of the inkjet head 40, and the like. Further, the recording control unit 56 executes data processing for driving the inkjet head 40 and generates a drive waveform.

A gyro sensor 58, a position detection sensor 8, an LED lamp 59, an inkjet head 40, a print button 14, a power button 15, a battery 51, etc. are electrically connected to the control board 57.

The gyro sensor 58 detects the inclination and the rotation angle of the HMP 1 by a well-known technique and sends the result to the control board 57. The LED lamp 59 is provided inside the exterior cover of the print button 14 made of a light-transmissive material, and causes the print button 14 to emit light.

When the power of the HMP 1 is turned on by pressing the power button 15, the power is supplied to each module, and the CPU 55 starts the activation operation based on the program stored in the ROM 54 and expands the program and each data in the RAM 53. When the image data is received from the external device by the short-range wireless communication, the recording control unit 56 generates a drive waveform according to the received image data. Then, the ejection of ink from the inkjet head 40 is controlled so as to form an image corresponding to the position on the surface of the recording material detected by the position detection sensor 8.

When the control board 57 shown in FIG. 5 obtains the image data by the short-range wireless communication with the external device, it blinks the LED lamp 59 to blink the light-transmitting print button 14. The user who sees this knows that the image data acquisition of the HMP1 is completed. After that, the HMP1 is placed on the recording material and the print button 14 is pressed.

On the other hand, when the control board 57 starts blinking control of the LED lamp 59, it waits for the print button 14 to be pressed. Then, when the print button 14 is pressed, the LED lamp 59 is continuously turned on, so that the print button 14 continuously emits light. The user who sees this starts a moving operation (manual scanning) of the HMP 1 in the scanning direction.

The user who has completed the moving operation (manual scanning) of the HMP1 picks up the HMP1 from the recording material and places it on a table or the like. The position detection sensor 8 cannot detect the position when the HMP 1 is picked up from the recording material. The control board 57 turns off the LED lamp 59 and stops the light emission of the print button 14 at the timing when the position detection sensor 8 no longer detects the position. The user who sees this can know that the process for printing the HMP1 is completed.

It is not necessary to continue pressing the print button 14 during the moving operation (manual scanning). If the print button 14 is pressed and released before the moving operation, the image forming process based on the detection result of the position detection sensor 8 is continued until the end of image formation or until the position detection sensor 8 cannot detect the position.

Next, the configuration of the jig according to this embodiment will be described.
FIG. 6 is a plan view showing a basic use state of the jig 100 according to this embodiment.
The jig 100 according to the present embodiment includes a long flat plate-shaped scanning orthogonal direction positioning reference member 101 extending in the scanning direction (X direction) of the HMP1 and a long flat plate extending in the scanning orthogonal direction (Y direction) of the HMP1. And a base member 102. The base material of the jig 100 is preferably a light-transmissive material and is transparent so that even if the jig 100 is placed on a sheet of paper (recording material) described later, the sheet of paper that overlaps the jig 100 can be visually recognized. It is more preferable.

In the jig 100 of the present embodiment, the side surface (the surface facing the scanning orthogonal direction) 101a extending in the scanning direction (X direction) of the scanning orthogonal direction positioning reference member 101 serves as the positioning reference of the HMP1 in the scanning orthogonal direction (Y direction). It functions as a scanning orthogonal direction positioning reference portion. That is, the position of the HMP1 in the scanning orthogonal direction (Y direction) is determined by pressing the side surface (for example, the back surface 34) of the HMP1 against the side surface 101a of the scanning orthogonal direction positioning reference member 101.

In the present embodiment, an example of forming a horizontally written image as shown in FIG. 6 will be described, but the same applies to the case of forming a vertically written image as shown in FIG. 7. However, as shown in FIG. 7, in the case of forming a vertically-written image, the front surface 35 of the HMP1 is pressed against the side surface 101b opposite to the scanning orthogonal direction positioning reference member 101 so that the front surface 35 of the HMP1 is scanned orthogonally. The HMP 1 is positioned in the direction (Y direction). Of course, even when a horizontal writing image is formed, the front surface 35 of the HMP1 may be pressed against the opposite side surface 101b of the scanning orthogonal direction positioning reference member 101 to position the HMP1 in the scanning orthogonal direction (Y direction). Even when a vertically-written image is formed, the back surface 34 of the HMP1 may be pressed against the side surface 101a of the scanning orthogonal direction positioning reference member 101 to position the HMP1 in the scanning orthogonal direction (Y direction).

Further, the scanning orthogonal direction positioning reference portion of the present embodiment is configured to regulate the displacement of the HMP1 on only one side in the scanning orthogonal direction, but may be configured to regulate the displacement of the HMP1 to both sides in the scanning orthogonal direction. For example, a groove extending in the scanning direction (X direction) is formed in the scanning orthogonal direction positioning reference member 101, and a protrusion provided on the HMP1 is inserted into this groove so that the inner wall surface of the groove is formed from both sides of the protrusion in the scanning orthogonal direction. It abuts and thereby regulates the position of the HMP 1 in the scanning orthogonal direction.

Further, on the scanning orthogonal direction positioning reference member 101 of the jig 100 of the present embodiment, one or more paper reference lines 111 as recording material reference lines extending along the scanning orthogonal direction (Y direction) are formed. ing. The paper reference line 111 is printed on the base material. By providing such a sheet reference line 111, a reference line segment on the sheet extending in the scanning orthogonal direction (for example, a line segment drawn on the sheet in the scanning orthogonal direction, a sheet end portion extending in the scanning orthogonal direction (end By setting the jig 100 on the paper so that (the side) etc.) is parallel to the paper reference line 111 of the jig 100, an image formed on the paper may be obliquely formed. Easy to control.

Further, in the jig 100 of the present embodiment, the side surface (the surface facing the scanning direction downstream side) 102a extending in the scanning orthogonal direction (Y direction) of the base member 102 as the scanning direction positioning reference member is the scanning direction (X direction). In the scanning direction, which serves as a positioning reference for the HMP1. That is, the position of the HMP1 in the scanning direction (X direction) is determined by pressing the side surface (for example, the left side surface 32) of the HMP1 against the side surface 102a of the base member 102. This position is the scanning start position (home position) of the HMP1.

The scanning direction positioning reference portion may be an index (mark) indicating the position in the scanning direction of a predetermined reference point (for example, the left side surface 32) on the HMP1. As the index, those printed or engraved on the base material can be used.

Here, in order to accurately form an image at a target position on the paper in the scanning orthogonal direction (Y direction), the image forming position in the scanning orthogonal direction at which an image is to be formed is set before starting the scanning of the HMP1. It is necessary to accurately align with the target position on the paper. To this end, a scanning orthogonal direction image forming position index (image position index) indicating an image forming position in the scanning orthogonal direction is arranged as close as possible to the image forming position, and the image forming position in the scanning orthogonal direction by the HMP1 is provided to the user. It is desired to accurately convey.

However, when an image is formed by scanning the HMP1, the image forming position is on the moving path of the HMP1 at the time of scanning, as shown in FIGS. Therefore, if the image position index is to be arranged as close as possible to the image forming position, the index member having the image position index will be present on the moving path of the HMP1, which hinders the scanning of the HMP1.

8A is a perspective view showing a state in which the indicator member 130 as an index member provided in the jig 100 of the present embodiment is located at the retracted position, and FIG. 8B is a perspective view. FIG. 3 is a perspective view showing a state in which the is located at a use position.
As shown in FIG. 8B, the jig 100 in the present embodiment is an index member in which image position indicating lines 131a and 131b are formed as image position indexes indicating image forming positions in the scanning orthogonal direction (Y direction). As an indicator member 130. The indicator member 130 is provided at a use position located on the moving path at the time of scanning the HMP 1 as shown in FIG. 8B and at a retracted position retracted from the moving path as shown in FIG. 8A. It is movably held by the scanning orthogonal direction positioning reference member 101.

The indicator member 130 is formed of a transparent member that is a light-transmissive member so that the portion of the sheet that overlaps the indicator member 130 can be visually recognized even when placed on a sheet (recording material). When this indicator member 130 is moved to the use position as shown in FIG. 8B, the image position indicating line 131a on the indicator member 130 contacts the side surface 101a of the scanning orthogonal direction positioning reference member 101 of the jig 100. The HMP1 set as described above is overlapped with the reference position (reference line) of the image forming position when the image is formed by scanning. Therefore, as shown in FIG. 9, the jig 100 in which the indicator member 130 has been moved to the use position has the image position indicating line 131a on the indicator member 130 at the target position in the scanning orthogonal direction (Y direction) on the paper P. When an image is formed by scanning the HMP1 set so as to abut on the side surface 101a of the positioning reference member 101 in the scanning orthogonal direction of the jig 100 by setting it on the paper P so as to overlap with a1. The reference position (reference line) of the image forming position can be accurately aligned with the target position a1.

Further, in the jig 100 according to the present embodiment, the indicator member 130 at the use position can be moved to the retracted position retracted from the moving path of the HMP 1 during scanning. Therefore, if the indicator member 130 is moved from the use position to the retracted position after the jig 100 is set on the paper P in this way, the indicator member 130 does not get in the way when the HMP 1 is scanned. Therefore, by setting the HMP 1 so as to contact the side surface 101a of the positioning reference member 101 in the scanning orthogonal direction of the jig 100 set on the paper P and scanning in the scanning direction (X direction), the indicator member 130 is set. An image can be accurately formed in the target area A on the paper P without any hindrance.

FIG. 10 is an exploded perspective view of the scanning orthogonal direction positioning reference member 101 holding the indicator member 130.
The scanning orthogonal direction positioning reference member 101 is a member in which the upper member 101A and the lower member 101B are fastened together while the indicator member 130 is sandwiched and held between the upper member 101A and the lower member 101B. A housing space B capable of housing the indicator member 130 is formed between the upper member 101A and the lower member 101B, and the indicator member 130 at the retracted position is housed in the housing space B. That is, the retracted position in this embodiment is set so that the indicator member 130 overlaps the scanning orthogonal direction positioning reference member 101. As a result, the area occupied by the indicator member 130 and the scanning orthogonal direction positioning reference member 101 in the plate surface direction of the scanning orthogonal direction positioning reference member 101 can be reduced by moving the indicator member 130 to the retracted position, thus saving space. To be done.

Particularly, in the present embodiment, the length of the indicator member 130 in the scanning orthogonal direction (Y direction) is equal to or less than the length of the scanning orthogonal direction positioning reference member 101 in the scanning orthogonal direction (Y direction). The directional positioning reference member 101 can be accommodated in both ends in the scanning orthogonal direction. Therefore, when the indicator member 130 is moved to the retracted position, the indicator member 130 does not stick out from the scanning orthogonal direction positioning reference member 101 to the outside in the scanning orthogonal direction, which is advantageous for space saving.

FIG. 11 is a plan view showing the indicator member 130 (the retracted position indicator member 130) housed in the scanning orthogonal direction positioning reference member 101.
The indicator member 130 of this embodiment is configured to be slidable along the scanning orthogonal direction (Y direction) with respect to the scanning orthogonal direction positioning reference member 101. Specifically, the indicator member 130 is formed with guide grooves 133 and 134 extending in the scanning orthogonal direction (Y direction) on the surface facing the lower member 101B. The indicator member 130 is held by the scanning orthogonal direction positioning reference member 101 so that the guide ribs 101d and 101e on the lower member 101B fit into these guide grooves 133 and 134. When the indicator member 130 is moved between the use position and the retracted position, the guide ribs 101d and 101e are guided by the guide grooves 133 and 134, which enables smooth sliding movement.

Further, the indicator member 130 of the present embodiment is movably held on both sides in the scanning orthogonal direction (Y direction) with respect to the scanning orthogonal direction positioning reference member 101. Therefore, the indicator member 130 accommodated in the scanning orthogonal direction positioning reference member 101 can be pulled out from one end side of the scanning orthogonal direction positioning reference member 101 in the scanning orthogonal direction, or the indicator orthogonal direction of the scanning orthogonal direction positioning reference member 101. It can also be pulled out from the other end.

Further, as shown in FIG. 11, the indicator member 130 of the present embodiment includes two elastic protrusions 135a and 135b at one end in the scanning direction. When the indicator member 130 is housed in the scanning orthogonal direction positioning reference member 101 (in the retracted position), the two elastic protrusions 135a and 135b have the scanning orthogonal direction positioning reference member 101 as shown in FIG. It is arranged so as to sandwich the step portions 101f and 101g formed on the lower member 101B. As a result, no matter which direction the indicator member 130 is moved in the direction orthogonal to the scanning direction (Y direction), one of the elastic protrusions 135a and 135b comes into contact with the stepped portions 101f and 101g, thereby hindering the movement. .. That is, the elastic protrusions 135a and 135b and the step portions 101f and 101g function as movement restricting means. As a result, the movement of the indicator member 130 from the inside of the scanning orthogonal direction positioning reference member 101 (the retracted position) is restricted, and it is possible to prevent the indicator member 130 from unintentionally moving from the retracted position.

FIG. 12 is a plan view showing a state where the indicator member 130 is being pulled out from the retracted position shown in FIG. 11 to the use position on the one end side in the scanning orthogonal direction. FIG. 13 is a plan view showing a state in which the indicator member 130 is pulled out to the use position on the one end side in the scanning orthogonal direction.
When pulling out the indicator member 130 housed in the scanning orthogonal direction positioning reference member 101 (at the retracted position) from one end side in the scanning orthogonal direction (left side in FIG. 11) to the use position, the user needs to touch the one end of the indicator member 130. The finger or nail is hooked on the hooking portion 132a formed on the upper surface of the side, and the indicator member 130 in the scanning orthogonal direction positioning reference member 101 is pulled out to the one side in the scanning orthogonal direction. At this time, as shown in FIG. 10, a cutout portion 101c is formed in the upper member 101A of the scanning orthogonal direction positioning reference member 101 at a position corresponding to the hook portion 132a of the indicator member 130. Therefore, even when the indicator member 130 is housed in the scanning orthogonal direction positioning reference member 101, the user can pull out by hooking a finger or a nail on the hooking portion 132a.

When the indicator member 130 housed in the scanning orthogonal direction positioning reference member 101 is pulled out to one end side in the scanning orthogonal direction (left side in FIG. 11), the elastic protrusion 135b of the indicator member 130 causes the step difference of the scanning orthogonal direction positioning reference member 101. It abuts the portion 101g. However, when the user pulls out with a certain force or more, the elastic protrusion 135b of the indicator member 130 is elastically displaced and can ride on the step 101g. As a result, as shown in FIG. 12, the restriction of movement of the indicator member 130 by the elastic projection 135b and the step portion 101g is released, and the indicator member 130 can be pulled out to one end side in the scanning orthogonal direction (left side in FIG. 11). ..

Particularly, in the present embodiment, the wall portion 101h on which the elastic protrusion 135b slides while the indicator member 130 is pulled out to the one end side (the left side in FIG. 11) in the scanning orthogonal direction is located at the center position of the two step portions 101f and 101g. The curved surface is located farthest from the downstream end (the lower side in FIG. 11) of the indicator member 130 in the scanning direction. As a result, while the indicator member 130 is pulled out toward the one end side in the scanning orthogonal direction, the elastic projection 135b gradually moves toward the center position of the two step parts 101f and 101g immediately after the elastic projection 135b rides on the step part 101g. The amount of elastic displacement decreases, and the dynamic frictional force between the elastic protrusion 135b and the wall 101h gradually decreases. On the other hand, while the indicator member 130 is pulled out from the center position of the two step portions 101f and 101g to the use position, the elastic displacement amount of the elastic protrusion 135b gradually increases, and the dynamic friction force between the elastic protrusion 135b and the wall 101h. Gradually increases. Then, as the elastic protrusion 135b of the indicator member 130 reaches the stepped portion 101f and descends from the stepped portion 101f, the indicator member 130 is located at the use position as shown in FIG.

With such a configuration, when the indicator member 130 accommodated in the scanning orthogonal direction positioning reference member 101 (at the retracted position) is pulled out from the one end side in the scanning orthogonal direction (left side in FIG. 11) to the use position, the user is fixed. After the elastic protrusion 135b of the indicator member 130 rides on the step 101g by applying the above force, the indicator member 130 can be pulled out with a small force. Immediately before reaching the use position, the user strengthens the force above a certain level and lowers the elastic protrusion 135b from the step portion 101f, thereby transmitting a click feeling to the user and confirming that the indicator member 130 has reached the use position. You can feel it intuitively.

Further, when the indicator member 130 located at the use position moves to return to the retracted position, the elastic protrusion 135b comes into contact with the stepped portion 101f, which hinders the movement. That is, the elastic protrusion 135b and the step portion 101f function as movement restricting means, the movement of the indicator member 130 from the use position is restricted, and the indicator member 130 unintentionally moves from the use position to the retracted position. It is possible to avoid the situation.

Further, in the present embodiment, even if the indicator member 130 located at the use position is further moved in the pull-out direction, as shown in FIG. 13, the guide rib 101e of the scanning orthogonal direction reference member 101 has the end portion of the guide groove 134. And its movement is restricted. That is, the guide rib 101e and the guide groove 134 also function as movement restricting means, and the indicator member 130 is restricted from moving from the use position, and the indicator member 130 is prevented from being unintentionally further pulled out from the use position. can do.

Note that when the indicator member 130 is further pulled out from the use position, the indicator member 130 separates from the scanning orthogonal direction positioning reference member 101, but in the present embodiment, the guide rib 101e of the scanning orthogonal direction reference member 101 is formed. By coming into contact with the terminal end portion of the guide groove 134, the detachment thereof is prohibited. That is, the guide rib 101e and the guide groove 134 also function as a disengagement prohibition unit that prohibits the indicator member 130 from disengaging from the scanning orthogonal direction positioning reference member 101.

FIG. 14 is a plan view showing a state where the indicator member 130 is being pulled out from the retracted position shown in FIG. 11 to the use position on the other end side in the scanning orthogonal direction. FIG. 15 is a plan view showing a state in which the indicator member 130 is pulled out to the use position on the other end side in the scanning orthogonal direction.
When pulling out the indicator member 130 housed in the scanning orthogonal direction positioning reference member 101 (at the retracted position) from the other end side in the scanning orthogonal direction (right side in FIG. 11) to the use position, the user needs to touch the indicator member 130. A finger or a claw is hooked on the hook portion 132b formed on the upper surface of the other end side, and the indicator member 130 in the scanning orthogonal direction positioning reference member 101 is pulled out to the other end side in the orthogonal scanning direction. At this time, as shown in FIG. 10, a cutout 101c is formed in the upper member 101A of the scanning orthogonal direction positioning reference member 101 at a position corresponding to the hooking portion 132b of the indicator member 130. Therefore, even when the indicator member 130 is housed in the scanning orthogonal direction positioning reference member 101, the user can pull out by hooking a finger or a nail on the hooking portion 132b.

When pulling out the indicator member 130 housed in the scanning orthogonal direction positioning reference member 101 to the other side in the scanning orthogonal direction (the right side in FIG. 11), the elastic projection portion 135a of the indicator member 130 causes the scanning orthogonal direction positioning reference member 101 to move. It contacts the step portion 101f. However, when the user pulls out with a certain force or more, the elastic protrusion 135a of the indicator member 130 is elastically displaced and can ride on the step 101f. As a result, as shown in FIG. 14, the movement restriction of the indicator member 130 by the elastic protrusion 135a and the step portion 101f is released, and the indicator member 130 can be pulled out to the other end side (the right side in FIG. 11) in the scanning orthogonal direction. it can.

Particularly, in the present embodiment, the wall portion 101h on which the elastic protrusion 135a slides while the indicator member 130 is pulled out to the other end side (the right side in FIG. 11) in the scanning orthogonal direction is the two step portions 101f, 101f, as described above. The central position of 101g is a curved surface that is farthest from the downstream end (the lower side in FIG. 11) of the indicator member 130 in the scanning direction. As a result, when the indicator member 130 housed in the scanning reference direction positioning reference member 101 (at the retracted position) is pulled out from the other end side (the right side in FIG. 11) in the scanning orthogonal direction to the use position, the indicator member 130 is scanned. Similar to the case of pulling to the one end side in the orthogonal direction, after the user applies a certain force or more and the elastic protrusion 135a of the indicator member 130 rides on the step portion 101f, the indicator member 130 can be pulled out with a small force. Immediately before reaching the use position, the user strengthens the force above a certain level and lowers the elastic protrusion 135a from the step portion 101g, thereby transmitting a click feeling to the user and confirming that the indicator member 130 has reached the use position. You can feel it intuitively.

Further, when the indicator member 130 located at the use position moves to return to the retracted position, the elastic projection 135a abuts the step 101g, which hinders the movement. That is, the elastic protrusion 135a and the step portion 101g function as a movement restricting unit, the movement of the indicator member 130 from the use position is restricted, and the indicator member 130 unintentionally moves from the use position to the retracted position. It is possible to avoid the situation.

Further, in the present embodiment, even if the indicator member 130 located at the use position is further moved in the pull-out direction, as shown in FIG. 15, the guide rib 101d of the scanning orthogonal direction positioning reference member 101 has the end portion of the guide groove 133. And its movement is restricted. That is, the guide rib 101d and the guide groove 133 also function as movement restricting means, and the indicator member 130 is prevented from moving from the use position, and the indicator member 130 is prevented from being unintentionally further pulled out from the use position. can do.

Note that when the indicator member 130 is further pulled out from the use position, the indicator member 130 separates from the scanning orthogonal direction positioning reference member 101, but in the present embodiment, the guide rib 101d of the scanning orthogonal direction reference member 101 is removed. By coming into contact with the terminal end portion of the guide groove 133, its detachment is prohibited. That is, the guide rib 101d and the guide groove 133 also function as a disengagement prohibition unit that prohibits the indicator member 130 from disengaging from the scanning orthogonal direction positioning reference member 101.

Further, the indicator member 130 of the present embodiment is formed with image position indicating lines 136a and 136b as image position indexes indicating the image forming position in the scanning direction (X direction). Therefore, when the indicator member 130 is moved to the use position as shown in FIG. 8B, the image position indicating line 136a on the indicator member 130 contacts the side surface 102a of the base member 102 of the jig 100. The set HMP1 overlaps with the reference position (reference line) of the image forming position when the image is formed by scanning. Therefore, as shown in FIG. 9, the image position indicating line 136a on the indicator member 130 is moved to the target position b1 in the scanning direction (X direction) of the jig 100 with the indicator member 130 moved to the use position. By setting it on the sheet P so that it overlaps with the sheet P, the HMP1 set so as to contact the side surface 102a of the base member 102 of the jig 100 is scanned to form a reference of the image forming position when the image is formed. The location (reference line) can be accurately aligned with the target position b1. Then, the HMP 1 is set so as to come into contact with the side surface 102 a of the base member 102 of the jig 100 set on the paper P, and the HMP 1 is scanned in the scanning direction (X direction), so that the target area A on the paper P is reached. An image can be accurately formed.

Next, an example of a procedure in the case of horizontally forming an image on the sheet P by the HMP1 using the jig 100 of the present embodiment will be described.
First, as shown in FIG. 9, the user first moves the jig 100 in which the indicator member 130 at the retracted position is moved to the use position so that the image position indicating line 131a on the indicator member 130 is in the scanning orthogonal direction on the paper P. The sheet P is set so as to overlap the target position a1 in the (Y direction). As a result, the reference position of the image forming position when the image is formed by scanning the HMP1 set so as to contact the side surface 101a of the positioning reference member 101 in the scanning orthogonal direction of the jig 100 is accurately set to the target position a1. Is aligned with.

Further, the user sets on the paper P such that the image position indicating line 136a on the indicator member 130 overlaps the target position b1 in the scanning direction (X direction) on the paper P. As a result, the reference position (image forming start position) of the image forming position when the image is formed by scanning the HMP1 set so as to contact the side surface 102a of the base member 102 of the jig 100 is the target position b1. Be accurately aligned to.

The user holds the jig 100 with one hand so that the jig 100 set in this way does not shift with respect to the paper. Then, the HMP1 is gripped with the other hand, and as shown in FIG. 16, the back surface 34 of the HMP1 is brought into contact with the side surface 101a of the scanning orthogonal direction positioning reference member 101 of the jig 100 with respect to the jig 100. Set HMP1. At this time, since the indicator member 130 of the jig 100 is still in the use position, the indicator member 130 is present on the moving path of the HMP1 during scanning, which hinders the scanning of the HMP1. The member 130 is moved to the retracted position.

The user may push the indicator member 130 in the use position to the retracted position with the other hand that is not holding the jig 100. However, in the present embodiment, as described above, the indicator member 130 of the jig 100 is held so as to be slidable along the scanning orthogonal direction (Y direction) from the use position to the retracted position, and with a certain force or more. By pushing, the indicator member 130 at the use position can be housed in the scanning orthogonal direction positioning reference member 101 (retracted position).

With such a configuration, the user performs the work of holding the HMP1 with the other hand, pressing the back surface 34 of the HMP1 against the indicator member 130, and pushing the indicator member 130 in the use position to the retracted position. be able to. In this work, the work of moving the indicator member 130 to the retracted position and the positioning of the HMP1 in the scanning orthogonal direction (Y direction) by bringing the back surface 34 of the HMP1 into contact with the side surface 101a of the scanning orthogonal positioning reference member 101 are performed. The work to be done can be done at the same time.

In particular, in the present embodiment, the elastic protrusion 135b and the step 101f that restrict the movement of the indicator member 130 at the use position are the base portion that is the scanning direction positioning reference among the both ends in the scanning direction of the indicator member 130. It is arranged on the side farther from the side surface 102a of 102. When the user pushes the indicator member 130 at the use position against the back surface 34 of the HMP 1 and pushes it to the retracted position, the user usually faces the side surface 102a of the base portion 102, which is the scanning direction positioning reference, rather than pushing straight in the scanning orthogonal direction. Easy to push diagonally. Therefore, as described above, when the elastic protrusion 135b and the step portion 101f are arranged on the side far from the side surface 102a of the base portion 102 which is the positioning reference in the scanning direction, the force for pushing the indicator member 130 obliquely is the indicator member. The elastic protrusion 135b of 130 acts in a direction in which it easily rides on the step 101f, and the movement restriction by the elastic protrusion 135b and the step 101f is easily released.

After the user moves the indicator member 130 to the retracted position and brings the back surface 34 of the HMP1 into contact with the side surface 101a of the scanning orthogonal direction positioning reference member 101 to position the HMP1 in the scanning orthogonal direction (Y direction), The left side surface 32 of the HMP1 is pressed against the side surface 102a of the base member 102 to position the HMP1 in the scanning direction (X direction). After positioning the scanning direction position of the HMP1 at the scanning start position (home position) in this manner, the user presses the print button 14 so that the back surface 34 of the HMP1 is aligned with the side surface 101a of the scanning orthogonal direction positioning reference member 101. The HMP1 is moved (manual scanning) in the scanning direction (X direction) so that the HMP1 moves. As a result, ink droplets are ejected from the ejection holes 41a of the recording unit 41 of the HMP1 according to the drive waveform generated by the recording control unit 56 of the HMP1.

By thus forming the image by the HMP1 using the jig 100, the image can be accurately formed at the target position a1 on the paper P in the scanning orthogonal direction (Y direction) and the scanning direction (X direction). It is possible to accurately form an image at the target position b1 on the paper P in (1).

Next, an example of a procedure for forming an image in vertical writing on the paper P by the HMP1 using the jig 100 of the present embodiment will be described.
First, as shown in FIG. 17, the user pulls out the indicator member 130 in the retracted position to the use position on the other end side (the right side in the drawing) in the scanning orthogonal direction. Then, as shown in FIG. 18, the jig 100 is placed on the paper P so that the image position indicating line 131b on the indicator member 130 overlaps with the target position a2 in the scanning orthogonal direction (Y direction) on the paper P. set. Accordingly, the reference position of the image forming position when the image is formed by scanning the HMP1 set so as to contact the side surface 101b of the positioning reference member 101 in the scanning orthogonal direction of the jig 100 is accurately set to the target position a2. Is aligned with.

Further, the user sets on the paper P such that the image position indicating line 136b on the indicator member 130 overlaps the target position b2 in the scanning direction (X direction) on the paper P. As a result, the reference position (image forming start position) of the image forming position when the image is formed by scanning the HMP1 set so as to contact the side surface 102a of the base member 102 of the jig 100 is the target position b2. Be accurately aligned to.

The user holds the jig 100 with one hand so that the jig 100 set in this way does not shift with respect to the paper. Then, the HMP1 is grasped by the other hand, and as shown in FIG. 19, the back surface 34 of the HMP1 is brought into contact with the side surface 101b of the scanning orthogonal direction positioning reference member 101 of the jig 100 with respect to the jig 100. Set HMP1. At this time, the user presses the back surface 34 of the held HMP 1 against the indicator member 130 to push the indicator member 130 at the use position to the retracted position.

When the user moves the indicator member 130 to the retracted position and brings the back surface 34 of the HMP1 into contact with the side surface 101b of the scanning orthogonal direction positioning reference member 101 to position the HMP1 in the scanning orthogonal direction (Y direction), The right side surface 33 of the HMP1 is pressed against the side surface 102a of the base member 102 to position the HMP1 in the scanning direction (X direction). After positioning the scanning direction position of the HMP1 at the scanning start position (home position) in this way, the user presses the print button 14 so that the back surface 34 of the HMP1 is aligned with the side surface 101b of the scanning orthogonal direction positioning reference member 101. The HMP1 is moved (manual scanning) in the scanning direction (X direction) so that the HMP1 moves. As a result, ink droplets are ejected from the ejection holes 41a of the recording unit 41 of the HMP1 according to the drive waveform generated by the recording control unit 56 of the HMP1.

By thus forming the image by the HMP1 using the jig 100, the image can be accurately formed at the target position a2 on the paper P in the scanning orthogonal direction (Y direction) and the scanning direction (X direction). It is possible to accurately form an image at the target position b2 on the paper P in ).

When forming an image over a plurality of lines using the jig 100 of the present embodiment, that is, when performing a plurality of times of scanning by changing the scanning position in the scanning orthogonal direction (Y direction), a plurality of times of image formation are performed. It is necessary to move the scanning orthogonal direction positioning reference member 101 by one line in the scanning orthogonal direction with respect to the paper. The jig 100 of this embodiment is configured such that the scanning orthogonal direction positioning reference member 101 is held so as to be movable with respect to the base member 102 in the scanning orthogonal direction (Y direction). Therefore, the scanning orthogonal direction positioning reference portion can be moved in the scanning orthogonal direction without moving the base portion. Thus, according to the jig 100 of the present embodiment, when the scanning orthogonal direction positioning reference member 101 is aligned with the next row, the scanning orthogonal direction positioning reference member is set on the basis of a predetermined reference position on the base member 102. The member 101 can be moved and aligned. Therefore, the alignment of the scanning orthogonal direction positioning reference member 101 with respect to the next row can be easily realized with high accuracy, and the image of the next row can be easily formed at an appropriate position.

Particularly, in the present embodiment, a scale 113 is formed on the base member 102 as a moving distance index indicating a moving distance of the scanning orthogonal direction positioning reference member 101 with respect to the base member 102. The scale 113 is printed on the base material, but may be formed by engraving or the like. Such a scale 113 serves as a reference position when aligning the scanning orthogonal direction positioning reference member 101 with the next row, and by moving the scanning orthogonal direction positioning reference member 101 with reference to this, the scanning orthogonal direction positioning reference member 101 is moved. The positioning reference member 101 can be accurately aligned with the next row.

In the case of forming an image over a plurality of lines using the jig 100 of the present embodiment (here, an example of horizontal writing will be described), first, the user, the base member 102 (or the base member 102 and the scanning orthogonal direction positioning reference member). (Both 101) and hold HMP1 with the other hand. Then, the side surface (back surface 34) of the HMP1 is pressed against the side surface 101a of the scanning orthogonal direction positioning reference member 101, and the HMP1 is moved (manual scanning) while positioning the HMP1 in the scanning orthogonal direction (Y direction). An image for one line is formed. Next, the user holds the base member 102 with one hand, releases the other hand from the HMP 1, and holds the scanning orthogonal direction positioning reference member 101 with the other hand. Then, with reference to the scale 113 of the base member 102, only the positioning reference member 101 in the scanning orthogonal direction is moved with the base member 102 fixed to the paper, and the position is adjusted to the next row. Thereafter, the user holds the HMP1 with the other hand while pressing the base member 102 (or both the base member 102 and the scanning orthogonal direction positioning reference member 101) with one hand, and the side surface 101a of the scanning orthogonal direction reference member 101 is held. The side surface (back surface 34) of the HMP1 is pressed against and the HMP1 is positioned in the scanning orthogonal direction (Y direction), and the HMP1 is moved (manual scanning) to form an image of the next row.

By repeating the above work, an image of three or more lines can be formed at an appropriate position.

FIG. 20 is a perspective view showing a state where the base member 102 and the scanning orthogonal direction positioning reference member 101 in the jig 100 of this embodiment are separated.
In the jig 100 of this embodiment, the base member 102 holds the scanning orthogonal direction positioning reference member 101 in a separable manner, and the base member 102 and the scanning orthogonal direction positioning reference member 101 are shown in FIG. Can be separated as follows. As a result, the base member 102 and the scanning orthogonal direction positioning reference member 101 are overlapped with each other so that their longitudinal directions coincide with each other, whereby the scanning orthogonal direction positioning reference member 101 is held by the base member 102 (both longitudinal directions thereof). The occupied space can be kept smaller than that in a state in which the directions are orthogonal to each other, and it becomes possible to store and carry in a small space.

In the jig 100 of this embodiment, the non-holding state in which the positioning reference member 101 in the scanning orthogonal direction is movable in the scanning orthogonal direction (Y direction) with respect to the base member 102 and the scanning orthogonal direction with respect to the base member 102. A switching unit is provided that can switch the positioning reference member 101 to a holding state in which the positioning reference member 101 cannot move in the scanning orthogonal direction (Y direction). By providing such a switching means, when the image is formed by the HMP 1 using the jig 100, the user only presses the base member 102 by hand, and the scanning orthogonal direction positioning reference member 101 moves in the scanning orthogonal direction (Y Direction) is fixed instead of moving. Therefore, when forming an image of a plurality of lines, it is not necessary to move one hand of the user holding the base member 102 even at the time of line feed, and workability is improved.

The switching means of the present embodiment is brought into a holding state by engaging the fixed concave portion or fixed convex portion provided on the base member 102 with the fixed convex portion or fixed concave portion provided on the scanning orthogonal direction positioning reference member 101, and these are held. By releasing the engagement, the non-holding state is obtained. Hereinafter, an example thereof will be described.

21A is a perspective view showing the back surface of the base member 102, and FIG. 21B is an enlarged view in which one longitudinal end portion of the fixed tooth 121 provided on the base member 102 is enlarged.
FIG. 22 is a cross-sectional view showing a cross section orthogonal to the longitudinal direction of the base member 102.
As shown in FIG. 21A, a fixed tooth 121 as a fixed concave portion or a fixed convex portion extending in the scanning orthogonal direction (Y direction) is provided at the downstream end of the base member 102 in the scanning direction (X direction). ing. The fixed teeth 121 are formed near the back surface (the surface facing the paper) of the base member 102. Further, the rotation shaft portion 122 scans orthogonally to the surface (opposite to the surface facing the paper) of the fixed teeth 121 so as to project in the scanning direction (X direction) from the fixed teeth 121. It is provided so as to extend in the direction (Y direction).

23A is a perspective view showing the back surface of the scanning orthogonal direction positioning reference member 101, and FIG. 23B is an enlarged view of one longitudinal end portion of the scanning orthogonal direction positioning reference member 101.
On the other hand, as shown in FIG. 23A, a fixed concave portion or a fixed convex portion extending in the scanning orthogonal direction (Y direction) is provided on the upstream side end portion of the scanning orthogonal direction positioning reference member 101 in the scanning direction (X direction). Fixed teeth 123 are provided. The fixed teeth 123 are formed near the back surface (the surface facing the paper) of the scanning orthogonal direction positioning reference member 101. Further, the shaft fitting portion 124 scans orthogonally so as to project in the scanning direction (X direction) from the fixed teeth 123 closer to the surface (the surface opposite to the surface facing the paper) than the fixed teeth 123. It is provided so as to extend in the direction (Y direction).

The rotation shaft portion 122 of the base member 102 has a substantially cylindrical shape as shown in FIGS. 21B and 22, and the shaft fitting portion 124 of the scanning orthogonal direction positioning reference member 101 is shown in FIG. 23B. As shown, the rotary shaft 122 has an arcuate cross-section. By fitting the rotating shaft portion 122 of the base member 102 into the shaft fitting portion 124 of the scanning orthogonal direction positioning reference member 101, the base member 102 can hold the scanning orthogonal direction positioning reference member 101. As shown in FIGS. 20 and 22, a stopper portion 125 is formed on the base member 102 at one end side in the longitudinal direction of the rotating shaft portion 122, and the stopper fitted to the rotating shaft portion 122 of the base member 102 is scanned. The shaft fitting portion 124 of the orthogonal direction positioning reference member 101 comes into contact with the stopper portion 125 so that it cannot move further toward the stopper portion 125 side.

When the scanning orthogonal direction positioning reference member 101 is attached to the base member 102, the longitudinal other end side of the rotation shaft portion 122 of the base member 102 (the stopper portion 125) with respect to the shaft fitting portion 124 of the scanning orthogonal direction positioning reference member 101. Insert from the side opposite to the end where the is formed. When the scanning orthogonal direction positioning reference member 101 is removed from the base member 102, with respect to the shaft fitting portion 124 of the scanning orthogonal direction positioning reference member 101, the rotation shaft portion 122 of the base member 102 on the other end side in the longitudinal direction (stopper). (The side opposite to the end where the part 125 is formed).

Here, in the present embodiment, as shown in FIGS. 24A and 24B, the scanning orthogonal direction positioning reference member 101 is rotated about the rotation shaft portion 122 as a fulcrum with respect to the base member 102. By making the back surface of 102 and the back surface of the scanning orthogonal direction positioning reference member 101 inclined with respect to each other, the scanning orthogonal direction positioning reference member 101 is not held with respect to the base member 102 (movable in the scanning orthogonal direction). ) Can be switched to. Specifically, as shown in FIG. 24B, the scanning orthogonal direction positioning reference with respect to the base member 102 until the rotation restricting portion 126 provided in the scanning orthogonal direction positioning reference member 101 abuts the surface of the base member 102. The member 101 is rotated. As a result, the fixed tooth 123 of the scanning orthogonal direction positioning reference member 101 is separated from the fixed tooth 121 of the base member 102, and the engagement between the fixed teeth 121 and 123 is released. As a result, the shaft fitting portion 124 of the scanning orthogonal direction positioning reference member 101 is slid along the rotation shaft portion 122 of the base member 102 to move the scanning orthogonal direction positioning reference member 101 in the scanning orthogonal direction (Y direction). Can be made.

On the other hand, as shown in FIGS. 25A and 25B, the scanning orthogonal direction positioning reference member 101 is rotated around the rotation shaft portion 122 as a fulcrum with respect to the base member 102 to scan the back surface of the base member 102 and the scanning direction. By making the back surface of the orthogonal direction positioning reference member 101 parallel to the base member 102, the scanning orthogonal direction reference member 101 can be switched to a holding state (a state in which it cannot move in the scanning orthogonal direction). More specifically, when the back surface of the base member 102 and the back surface of the scanning orthogonal direction positioning reference member 101 are in a parallel state, as shown in FIG. 25B, the fixed teeth 121 of the base member 102 and the scanning orthogonal direction positioning reference member are provided. The fixed teeth 123 of 101 mesh and engage with each other. As a result, the shaft fitting portion 124 of the scanning orthogonal direction positioning reference member 101 cannot slide along the rotation shaft portion 122 of the base member 102, and the scanning orthogonal direction positioning reference member 101 is in the scanning orthogonal direction (Y direction). ) Becomes impossible to move.

According to the above configuration, the user only presses the base member 102 by hand, and the holding position of the scanning orthogonal direction positioning reference member 101 is fixed without moving in the scanning orthogonal direction (Y direction). Therefore, when forming an image of a plurality of rows, when moving the scanning orthogonal direction positioning reference member 101 to the next row, the user rotates the scanning orthogonal direction positioning reference member 101 in the held state to unhold it. Then, with the base member 102 fixed, the scanning orthogonal direction positioning reference member 101 is moved (slide) in the scanning orthogonal direction (Y direction). Then, after moving (sliding) to the position of the next row, the scanning orthogonal direction positioning reference member 101 is rotated so as to be in the holding state. Accordingly, the scanning orthogonal direction positioning reference member 101 is fixed without moving in the scanning orthogonal direction (Y direction), so that the image formation of the next row can be appropriately performed.

As described above, the switching means capable of switching between the holding state and the non-holding state is not limited to the configuration of this embodiment. For example, the configuration may be such that the back surface of the base member 102 and the scanning orthogonal direction positioning reference member 101 are kept parallel to each other, and the scanning orthogonal direction positioning reference member 101 is moved in a direction away from the base member 102. .. However, as in the present embodiment, if the scanning orthogonal direction positioning reference member 101 is rotated with respect to the base member 102, the holding state and the non-holding state can be easily and quickly switched, High convenience can be obtained.

The meshing pitch of the fixed teeth 121 and 123 of this embodiment is set to 1 mm, but can be set as appropriate. For example, if the meshing pitch is expanded to 5 mm, it becomes easy to align the scanning orthogonal direction positioning reference member 101 at the time of line feed with respect to the specified line spacing corresponding to this pitch. On the contrary, if the meshing pitch is narrowed, the degree of freedom of alignment of the scanning orthogonal direction positioning reference member 101 at the time of line feed is increased.

In addition, the jig 100 of the present embodiment is configured such that the coefficient of friction between the table surface on which the paper is placed or the contact surface (rear surface) that contacts the upper surface of the paper is the jig surface or the upper surface of the paper. A friction member 150 that is higher than the base material surface of 100 is provided. The friction member 150 functions as a slip stopper for the jig 100 with respect to the table surface or the sheet, and suppresses relative displacement between the sheet and the jig 100.

In addition, in the present embodiment, an initial position index 114 indicating the initial position (the initial position of the movement in the scanning orthogonal direction) of the scanning orthogonal direction positioning reference member 101 with respect to the base member 102 is provided on the base member 102. .. Thus, when forming a plurality of rows of images, the user can set the reference position of the scanning orthogonal direction positioning reference member 101 to the scanning orthogonal direction position indicated by the initial position index 114 on the base member 102 when forming the image of the first row. (In the example of FIG. 6, the central position in the scanning orthogonal direction of the scanning orthogonal direction positioning reference member 101) is aligned and brought into the holding state. Then, when forming the image of the next row, the non-holding state is set, and the scanning orthogonal direction positioning reference member 101 is aligned with the next row on the basis of the initial position index 114. Positioning is similarly performed on the third and subsequent lines. As a result, it is possible to form an image of another row at an appropriate position in accordance with the first row.

In particular, in the present embodiment, at the reference position of the scanning orthogonal direction positioning reference member 101 (center position of the scanning orthogonal direction positioning reference member 101 in the scanning orthogonal direction), a reference position indicating line 117 or a reference position indicating line 117 is used as a reference position index indicating the reference position. Protrusions 118 are provided. Therefore, at the time of image formation of the first row, the reference position indicating line 117 and the protrusion 118 of the scanning orthogonal direction positioning reference member 101 are aligned with the initial position index 114 of the base member 102, and the next row is the initial position of the base member 102. The position of the scanning orthogonal direction positioning reference member 101 may be aligned with the next row by the distance between the position index 114 and the reference position indicating line 117 of the scanning orthogonal direction positioning reference member 101 or the protrusion 118.

In addition, in the present embodiment, the jig including both the scanning orthogonal direction positioning reference portion and the scanning direction positioning reference portion has been described, but the jig may include only one of the positioning reference portions. ..
Further, in the present embodiment, the configuration in which the indicator member 130 that moves between the use position and the retracted position moves along the scanning orthogonal direction (Y direction) has been described, but along the scanning direction (X direction). It may be configured to move. In this case, for example, the indicator member 130 may be held by the base member 102.

Further, in the present embodiment, the example in which the portable image forming apparatus is the inkjet type HMP1 has been described, but the portable image forming apparatus may be a portable image forming apparatus using another image forming method. For example, it may be a portable image forming apparatus of an appropriate image forming system such as a thermal system or a thermal transfer system.
